Abstract: ABSTRACT         Apparatus for generating an acoustic pulse in a medium wherein an impact piston is driven downwardly along a cylindrical housing by compressed gas to strike a rigid target positioned in contact with the earth.  In its firing position, the tapered upper portion of the piston extends above the top of the housing within a container occupied by the compressed gas, the top of the piston being at the same time recessed within a gastight mating enclosure at the top of the container.  In this position, the tapered piston surface is constantly exposed to circum-ferential gas pressure so as to provide a positive breakaway force.  Upon release of suitable piston latch means, the piston is first urged downwardly by this breakaway force and thereafter accelerated more powerfully when the top of the piston separates from the enclosure and becomes exposed to gas flow uniformly from all directions.

Abstract: ABSTRACT          The bulkhead of a solid refuse transport vehicle of the type having a tilting bucket and a tilting packer plate the free end edge of which discharges the contents of the bucket is improved by providing the packer plate with a convex protrusion extending transversely of the packer plate and disposed near the discharge opening, to improve the pre-compacting of the refuse before its dis-charge from the bulkhead.  The improved arrangement can be combined with a further feature of the invention whereby a standard, rectangular refuse container is releasably held in abutment with the bulkhead.

Abstract: Abstract A method and apparatus for determining by measurement the temperature rise in an energized a.c. winding of a transformer using the principle of measuring resistance change is described.  A first measurement of the resistance of the a.c. winding is taken with the a.c. winding unenergized at a datum temperature  The corresponding electrical output signal is used to calibrate the apparatus, such that at any increased temperature the ratio of the resistance when hot (RH) of the resistance of the winding when cold (RC) is calculated and displayed on a ratiometer.  This is achieved by utilising a particular circuit arrangement in which the component values are selected such that the d.c. signal extracted from the energized a.c. winding is directly related to the resistance of that winding only.  The resistance measurement is substantially independent of the effect of the resistance of the connecting leads of the measuring circuit.  A permanent recording of the resistance change of the winding under test can be obtained.          The ratio of the resistances can be modified using a well known formula such that a direct windings temperature or temperature change in degree Celsius can be displayed.  The apparatus and circuitry of the present invention can be used to measure the temperature changes in an a.c. winding of a motor.

Abstract: ABSTRACT      A circular seal configuration is shown for sealing the annular clearance between an inner cylindrical member and an outer cylindrical member.  A center portion of the seal is made of a compliant elastomer material and is adapted to seal both against the internal diameter of the outer  cylindrical  member  and  against  the  external diameter of  the  inner cylindrical member.   A pair of external backup rings circumscribe the exterior surface of the elastomeric center portion and a pair of internal backup rings circumscribe the interior  surface of the elastomeric center portion.  The backup rings are of a relatively stiff material but expand independently upon the application of pressure to the elastomeric portion of the seal to provide a zero clearance fit with respect to the surrounding sealing surfaces and prevent extrusion of the elastomer which would cause a seal failure.

Abstract: Abstract Proving Safe Operation To ensure the safe operation of an electronic circuit, for example an amplitude modulated carrier signal generator, an output of the circuit is analysed to prove the presence of predetermined signal characteristics, for example the carrier signal, or a modulation frequency.  The predetermined signal alternatively may be superimposed on an input to the electronic signal and proved subsequently to be present in the output.  The output of the circuit is passed inhibited, according to whether or not the signal characteristics are proved present, by means of an output enable gate which is self-latching providing the output continuous to be proved correct.  A start-up circuit delays a possible inhibit for a limited period following initial power connection to the circuit in order that the output can become established.
