A Bingo card support which includes a support frame provided with projecting card support members, which support members are, in one embodiment, capable of retraction in recessed configuration against the support frame surface to provide a substantially unobstructed plane which enables the support frame to be used as a table. Various leg configurations facilitate orientation of the support frame at an angle to display multiple Bingo cards resting on the support members in one variation and to orient the support frame in a horizontal position with respect to the supporting surface, in another variation.

A calipering tool for use in a pipe and having a body and feeler means mounted with the body for engaging the surfaces of the pipe being calipered and with feelers moving in response to variations in the surface of the pipe, the improvement residing in mechanisms with the body for permitting the body of the calipering tool to be pumped in response to fluid pressure thereon into and out of the pipe for operation of the calipering tool.

Calipering tool

A calipering tool for use in a pipe and having a body and feeler means mounted with the body for engaging the surfaces of the pipe being calipered and with feelers moving in response to variations in the surface of the pipe, improvements residing in pairs of stylus members, including active and base-line styli, each active stylus adapted to engage a chart and move relative thereto in response to movements of a feeler and with each base-line stylus adapted to engage the chart adjacent the active stylus for providing an individual base-line for the respective active stylus for providing accurate dimensional recording and continuing thermal calibration of the calipering tool in response to temperature variations encountered within the pipe and a new removable stylus assembly capable of being removed from the calipering tool as a unit for repair and/or replacement as is necessary without requiring replacement of the entire calipering tool.

A new and improved signal-producing pipe caliper adapted to be moved through a section of pipe to detect internal variations in the inside surface of the pipe, and to transmit analog signals corresponding to such variations for suitable recording at a location which is remote from the caliper; such caliper having individual caliper feelers which are separately removable and replaceable without disturbing the electrical signal system, whereby replacement, including size changes of the caliper feelers for accommodating different inside diameters of the pipe being calipered, and/or repair may be accomplished in the field rather than requiring the return of the caliper to the shop.

Signal-producing pipe caliper

An apparatus for generating a series of seismic acoustic pulses in a body of water. The series is characterized by having continuously-variable, non-repetitive time intervals between successive pulses during a continuous seismic recording. The preferred generator is an air gun comprising a variable-speed motor with a rotating cam for actuating a sleeve valve which alternately opens and closes exhaust ports in a high-pressure chamber. As the valve repeatedly opens, jets of high-pressure air are impulsively expelled into the surrounding water, thereby generating an underwater acoustic pulse train.

Marine acoustic pulse train signal generator

A motor driven machine, such as a machine capable of holding and imparting movement to a tool, for example, which may be an eraser strip that is brought to bear upon a surface, such as a paper surface, for erasure of undesirable markings therefrom. The machine includes an internal air supply mechanism having the capability of directing a flow of compressed air against the work surface in the area of contact between the tool and the surface for the purpose of cooling the surface and the tool as well as blowing particles from the immediate area of engagement between the tool and the surface. The machine may include a holding device for supporting the machine in proper position to be grasped when the machine is not in use.
