Abstract: ABSTRACT OF THE DISCLOSURE           An improved thermal switch permitting large tempera-ture excursions beyond the design closure temperature without stressing the switch material beyond its elastic limits.  It combines a bimetal portion with a spring portion through which movement is transmitted, the former providing sufficient de-formation for closure at design temperature, and the latter accommodating excess deformation beyond closure caused by high temperature.  It is particularly useful in metal halide lamps having gas filled outer envelopes and requiring shorting of an auxiliary starting electrode to the adjacent main elec-trode during operation.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a valve assembly adapted in conjunction with a valve actuator to provide positive control of the stroke of hydraulic cylinders.  The valve is attached to a pressure port on the cylinder and the actuator assembly is positioned on the side of the cylinder and held by means of clamps.  The stroke of the cylinder is limited when the actuator arm is clamped on the piston shaft at a distance shorter than the full stroke of the cylinder.  In this con-dition as the shaft moves into the cylinder, the actuator arm contacts closure means within the valve thereby closing off the valve and preventing further retraction of the cylin-der.  The apparatus of the invention is adapted to be sup-plied in the kit form and can be readily attached, exter-nally to any existing hydraulic actuator.

Abstract: ABSTRACT OF THE DISCLOSURE        A fish counter primarily for counting migrating salmon in streams includes a narrow beamwidth side-scanning sonar transducer which is directed to insonify a volume of water in the stream directly above a mechanical structure serving as an artificial bottom.  This structure consists of a lightweight, ladder-like frame with transverse support members of arcuate form over which is stretched a thin skin of sheet metal such as aluminum, thereby providing a structure of great stiffness to avoid sagging.  The transducer is supplied with transmitting pulses of short duration at regular intervals.  After a delay, a receiver is enabled to permit reception of echo signals returning from any fish crossing the artificial bottom.  During the period the receiver is enabled, a ring counter separates the return echoes on the basis of the return time from respective sectors of the bottom structure, and these returns are separately counted for each sector to permit each sector to be read out separately or printed out separately.  To separate debris from the fish returns, sampling rates are provided such that each fish is sampled five times but only three valid detections are required at the input to the storage registers to insure a count.  Other combinations of these numbers may be used.  The counts may be accumulated in total, may be printed out on a sector-by-sector basis, or individual sector counts per given time period may be displayed as requested by an operator.  To eliminate inordinately high counts from long term debris which may become fastened to the structure, a counter arrangement is provided which receives all the counts on a sector-by-sector basis and responds to an excessively large number in any sector by disabling that part of the ring counter so that no further counts are accumulated for that sector.  The disabled sector remains disabled until the passage of a preset time period of, for example, several minutes after which the counter is cleared.  If obstruction remains, the ring counter is again disabled.  This condition may be indicated on the print-out tape by means of a special character representing debris.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides for a cartridge for lubricant which is designed for use in an air line lubricator.  The cartridge comprises a rigid sleeve defining an outlet nozzle for lubricant at its one end, with the other end being open and directed in use into the stream of pressure air flowing through the lubricator.  A flexible sock with its   mouth region secured within the sleeve acts physically to separate lubricant in the sleeve from the pressure air, the body length of the sock being sufficient to permit exhaustion of lubricant from the sleeve.  The sock may be secured within the sleeve midway therealong, or at its open end.  In the latter case a method of charging the sleeve in accordance with a further aspect of the invention comprises locating a second sleeve within the cartridge sleeve so that during the charging process the sock is folded back on itself through the action of the secondary sleeve.  After charging the secondary sleeve is withdrawn.

Abstract: ABSTRACT OF THE DISCLOSURE           An automotive ceiling panel and a process for manu-facturing the same and more particularly, to a process which reduces the weight of the panel and the man-hours required for the manufacture thereof and yet results in an improvement in the quality of the panel.  The ceiling panel comprises a laminate of a first polyethylene foam layer having an aesthetically de-signed crimp-pattern in its layer surface, a second metal lath laid under the first polyethylene foam layer, and a third layer of polyethylene foam laid under the metal lath.  The metal lath is sandwiched between the polyethylene foam layers, with the crimp-pattern appearing on the top surface of the panel.  A process of manufacturing the automotive ceiling panel comprises the steps of forming a crimp-pattern in the surface of a first polyethylene foam layer by a crimp-pattern forming machine, placing a metal lath between the first and a second polyethylene foam layer, with the crimp-pattern carrying surface of the first polyethylene foam layer appearing on the top surface of the first layer, bodning the thus laid layers together using fusion-bonding and rolling techniques, and cold-pressing the laminate thus pre-pared into a desired shape for an automotive ceiling.
