A power device for splitting a log into four pieces avoids the problems of sticking the log on the wedge by positioning the splitting assembly to permit the split portions of the log to separate as vertical is started prior to horizontal splitting.

A method of testing coating integrity of containers includes the steps of introducing a probe into an electrolytic solution into the container and applying a constantly-increasing voltage to the probe from a source and taking readings of the voltage when the current flow through the container reaches a predetermined level. The apparatus also includes a gripping mechanism for producing a positive contact between the metal in the container and the remainder of the circuit.

Shown is an apparatus for mounting an inductive transducer in position over an intermittently moved belt carrying easy open ends for a beverage container and designed to detect whether or not the tabs for easy opening are provided on the ends. The apparatus is designed to resiliently bias the detection transducer towards the ends with a predetermined gap therebetween such that an electrical signal will result that can be used to evaluate whether a tab is in place. The apparatus includes a camming ramp designed to trigger a limit switch to turn off the system should there be multiple ends positioned below the detector. The detector mounting on a resilient support is designed to back away from any obstruction therebeneath to protect the apparatus during the detection operation. The transducer face is protected by about 1/16 inch of the plastic material. Also shown is a process of monitoring easy open ends in order to determine whether there are tabs on the ends including the steps of positioning the ends below an inductive transducer at a preset position relative to the end, generating an output voltage which corresponds to the distance of the metal mass in the end relative to the inductive transducer and comparing the output of the transducer with a predetermined value to establish whether or not there is indeed a tab on the end.

A system for the reject of a single container from a row of multiple closely spaced containers on a moving conveyor. A circuit supplies a signal to a reject mechanism which is a solenoid actuated air blast to remove the container accurately. The circuit combines a shift register output with blanking signals in a first gate and a container position control sensing signal with the output of the first gate in a second gate to produce the appropriate reject signal. Mechanical fine tuning is provided to enable positioning the container signal within the appropriate time window.

To measure the relative power during a welding process, a position sensitive transducer is attached to a welding electrode to submit a signal in response to electrode motion. An accelerometer, carried on an axle of an electrode roll for a Soudronics pulse type resistance welder, will emit a signal indicative of the quality of the weld. The accelerometer measures the forging taking place during welding by means of its position sensitivity and the amount of forging has been found to be a function of the characteristics of the weld.

A temperature compensating circuit for taking into account operating temperature changes of a Hall effect transducer to compensate for Hall output DC offset changes using a resistance circuit including a thermistor for offset feedback control of an operational amplifier in accordance with varying temperature. The circuit also includes a load response input portion to power the Hall effect transducer to compensate for Hall gain change versus temperature.

A laboratory stand assembly includes a stand having a post, a sample holder bracket mounted on the post, a sample holder disengageably supported on the holder bracket, a probe mounting member adapted to support a probe, and a probe bracket mounted on the post which supports the probe member in both of two alternate positions. The stand assembly is especially suited for use in connection with the analysis of solder compositions, wherein a probe is inserted into a heated solder sample to monitor its cooling characteristics.

An inspection apparatus for inspecting and detecting flaws in serially fed substantially cylindrical objects. The inspection apparatus includes a notch-shaped inspection station formed by a pair of drive wheels mounted on a first shaft and a pair of discharge wheels fixedly mounted on a second shaft, parallel to the first shaft. A hook having a convex back surface is connected to and protrudes beyond the circumference of each discharge wheel. An L-shaped bracket whose body includes a sending surface and whose leg includes an infeed cradle, is mounted above the drive wheels and pivots in synchronism with the rotation of the discharge wheels. A first object in the infeed cradle is positively sent by the bracket sending surface toward the inspection station as the hook convex back surfaces are rotating up through the inspection station. The sent first object contacts the hook back surface which by its clockwise rotational motion imparts a counterclockwise rotational motion to the object while easing it into the inspection station where it is rotated and inspected for flaws by sensors mounted axially on an imaginary straight line drawn from the axial center line of the inspection station to the axial center of the first or second shaft.

A method and apparatus for orienting cylindrically shaped containers having a side seam in each which is parallel to the longitudinal axis of the container so that operations may be performed on the containers utilizing known and oriented reference points thereon. The method and apparatus for accomplishing this result includes feeding the containers seriatim at a first station to a means for conveying the containers to a second station whereat it is necessary that the containers be oriented in order for an operation to be performed thereon. conveying the containers seriatim from the first station to the second station, and introducing a fluid under pressure and at a volume sufficient to buoy the containers to thereby permit gravity to orient the side seams of the containers in preparation for delivery of the containers seriatim to said second station.

Flow control apparatus and method for controlling the flow of gravity fed substantially cylindrical objects through a gravity runway wherein a starwheel, a star-shaped ferrous pulse rotor and a ferrous rotor are each spaced from each other and axially fixed to a free wheeling shaft mounted in a frame connected to a gravity runway such that the starwheel lobes jut into and rotate through the gravity runway. Each starwheel lobe engages each of a successive line of gravity cans as the cans fall through the runway. A magnetic sensor is mounted on the frame near the star-shaped pulse rotor such that as cans free fall past the starwheels and rotate the free wheeling shaft star points on the pulse rotor rotate past the sensor and disturb the sensor's emitted magnetic field. For each disturbance, the sensor emits an electrical pulse signal. Each pulse signal is transmitted to stator coils which extend radially inward on a fixed stator housing concentrically surrounding the rotor such that each pulse signal is capable of magnetically attracting a rotor pole to a stator pole thereby retard rotation of the rotor for the duration of the pulse signal. If the voltage amplitude of the pulse signal exceeds a pre-set threshold voltage a signal of controlled duration is transmitted to energize all of the coils and stator poles to momentarily attract the rotor poles and retard the can flow through the runway.
