A protective firefighting vehicle comprising a chassis conceived for heavy loads, a driving gear for rough terrain and a tank mounted on the chassis for receiving liquids such as water or fire-extinguishing agents or the like. The tank is divided in at least two chambers via at least one bulkhead-like partition. Provision is made in this connection that at least one of the chambers of the tank can be sealed off in a liquid-tight manner against at least one other chamber of the tank in order to permit the transport of persons in the at least one sealable chamber.

An arrangement for measuring distortion in cylinders. A sensor projects straight out of the end of a motion-transmitting arm. The arm can be both translated and rotated. The sensor accommodates a probe that probes the geometry of the surface of the cylinder. The sensor has a distortion-measuring structure accommodated in the head of a surface-geometry probe and a check for axially secured and undeflected tensioning of the probe. The probe is an elongated geometry-probing pin. The structure is securely tensioned remote from the chuck in the vicinity of a structure-attachment section in the head. The structure includes at least one zone of attenuation between the chuck and the structure-attachment section and has a resilient section and a strain gauge.

Instrument for simultaneously measuring a succession of cylinder bores

An arrangement for measuring the distance between the axles or wheels of a vehicle. A roadway with at least one sensing sill. A sensing section along the roadway with one end a maximum length from the sill corresponding to the smallest spacing between axles to be measured and another end a minimum length from the sill corresponding to the largest spacing between axles to be measured. A first wheel on a first axle of the vehicle being located at the sensing sill and a second wheel on a second axle on the vehicle being located on the sensing section when measuring the distance between the two axles by using the distance measured between the second wheel and the sensing sill.

Method of measuring the distance between the axles or wheels of a

For the purposes of measuring the configuration of cylinder bores, at least one measuring probe with a plurality of measuring sensors each having respective radially projecting sensing pins is introduced into the cylinder bore, without the sensing pins touching the cylinder bore, and the sensing pins are then brought into contact with the cylinder wall by relative displacement of the workpiece and the measuring probe with respect to each other. Thereupon the measuring head is fixed with respect to the workpiece and that fixing is maintained by means of a biasing force, whereupon, with the workpiece resiliently seated and with the measuring head decoupled from members which produced the advance movement thereof, the configuration of the cylinder bores is measured by sensing by means of the sensing pins on adjacent parallel circles. The apparatus has at least one measuring probe but preferably a plurality of measuring probes which are arranged in terms of number and position in accordance with the cylinder bores to be measured, the measuring probe or probes being associated with a measuring head which can be decoupled in the measuring position.

A measuring arrangement for form measurement of cylinders, comprises a measuring arm insertable into a cylinder space, a measuring sensor which is guided by the measuring arm, movable translatorily in the direction of a longitudinal axis of the measuring arm and driveable independently of the measuring arm in a circumferential direction, a sensing pin which is displaceable radially and along an axis of the measuring sensor and arranged for sensing a geometry of walls of cylinders, a driving arm which is movable translatorily and rotatably and having an end, the measuring arm being formed as a thin sensing body which is in operative connection with the end of the driving arm, formed bending-resistant, and extends parallel to the driving arm, the sensing body having an end which is spaced from the driving arm and carries the measuring sensor, and the measuring sensor being provided with the sensing pin.

In a method of opto-electronic inspection of a two-dimensional pattern on an object, especially a printed board, a micro-inspection is carried out by subjecting line-by-line scanned picture elements in pixel-by-pixel fashion to a sequence of picture operations for inspection of dimensions and spacings, and the respective result is compared with the corresponding scanned pixel. At the same time a macro-inspection is carried out by combining the scanned pixels to frames and by respective reduction thereof to a single characteristic picture information, whereupon a comparison is again performed, but this time with the corresponding picture information of a reference picture. In this way it is possible to perform a quick and fully automatic real-time inspection of two-dimensional patterns, for instance printed boards, both for minute and hardly visible defects and for macro-defects.

A wheel load indicator comprises a rectangular flat plate (1) of a light material having measuring properties. A series of recesses (4) forming webs (5) are provided along two lateral edges (6) of the plate (1). Strain gauges (12) are adhesively bonded to walls of bores (10) in the area of the webs (5) to determine the shearing stress under the load of a wheel (100) which has driven on the bending portion (3).

A measuring device for hollow cylindrical surfaces, such as bores and the like, comprises a housing to be fixed in the bore by clamps, a measuring arm rotatable by a first step motor, a measuring head axially movable along the measuring arm substantially parallel to the axis of the bore surface by a second step motor and a sensor incorporated in the measuring head and radially movable relative to the measuring head against the force of a leaf spring in contact with the bore surface. The leaf spring supports strain gauges, the output signals of which are representative of the radial or transverse paths of the sensor and thereby for the shape of the bore surface to be measured.

System for positioning and maintaining position stabilization of a mass such as a barrelled gun supported on a base such as a tracked vehicle. The system employs oppositely rotating disks with fluid actuated clutches for moving the gun barrel mass in a single degree of freedom as determined by a deviation from a predetermined setting.
