Abstract: Abstract of the disclosure An apparatus for a detecting the location of incident radiation cimprises at least one pair of assembly comprised of a scintillation crystal consisting of a plurality of crystal segments, a pair of photo-multiplier tubes optically coupled to the scintillation crystal so as to be able to detect a scintillation produced in any one of these crystal segments.  These plural crystal segments are coupled to each other in such manner that any scintillation produced in any single crystal segment will cause the photo-multiplier tubes to deliver substantially a same output irrespective of the illumi-nating position within this crystal segment, and also that scintillations produced in the respective crystal segments will cause the photo-multiplier tubes to deliver outputs which are different in level for the respective crystal segments.

Abstract: ABSTRACT:         A motion-transmitting device, e.g. a torque converter, for transmission of rotary motion makes use of a toothed wheel in which each recess between adjacent teeth is a portion of an ovoid hole.  A datum plate has ovoid holes equidistantly arranged about a centre eccentric with respect to the wheel.  Connector pins engage with rolling motion the holes in the datum plate and the recesses between the teeth, entering into and out of engagement with the wheel as the wheel is driven eccentrically with respect to the datum plate.  The number of pins and holes differs from, preferably by unity, the number of teeth.  Of the three integers, wheel, eccentric and datum, one forms the input, one the output and the third is the fixed reference.

Abstract: DRIVE MECHANISM                     ABSTRACT          A drive mechanism has a frame, a drum and a first element rotatable relative to the frame.  A driving element is mounted on and rotatable with the first element.  Apparatus, such as a hydraulic motor and pinion gear, engages and rotates the driving ele-ment.  Apparatus, such as a brake and pinion gear engages and controllably blocks the driving element from rotation.  Final drive apparatus transfers rota-tional motion from the first element to the drum, which can be, for example, the drum of a compactor inside of which the drive mechanism is located.  The orientation of the elements of the drive mechanism reduces its width which frees more area inside the space limited drum and eliminates the need to mount components exteriorly to the drum where they can be damaged.

Abstract: RETORT CRATE LOADER AND UNLOADER                          ABSTRACT           A semi-automatic retort crate loader and unloader is disclosed.  A standard retort crate is positioned adjacent the outer edge of a dead plate at one end of a conveyor by horizontal positioning assembly which includes a clamp and a pair of crate sensors.  A floor cylinder raises and lowers the bottom of the retort crate and the containers therein. Jar load and unload sensors control indexing the floor cylinder to the proper heights for loading and unloading layers of containers into and out of the retort crate. During loading, the horizontal positioning assembly positions the crate so that the inner surface lies underneath the dead plate and behind its outer edge.  A jar clamp, located above the dead plate and having a resilient lower surface, clamps jars to the outer edge of the dead plate after the retort crate is filled.  The horizontal positioning assembly then moves the carriage and retort crate therewith away from the dead plate a short distance providing seating space for imperfectly clamped jars.  The containers are then indexed down one level via the floor cylinder and jar loading sensor. The horizontal positioning assembly then moves the retort crate back under the dead plate.   A circular sweep ring having a downwardly and outwardly beveled interior surface is also disclosed.  During unloading, the horizontal position assembly, jar unload sensor, floor cylinder and sweep ring combine to position the crate, index the layers of containers and sweep the upper layer onto the conveyor.

Abstract: ABSTRACT OF THE DISCLOSURE      Several embodiments of reduced crosstalk ribbon cable (30, 60, 90) having alternating twisted (32, 62, 92) and straight (34, 64, 94) sections of indef-inite length are disclosed, crosstalk being reduced by differing starting positions of alternate twisted pairs, differing lay of alternate twisted pairs, and variation in lay along the length of alternate twisted pairs.  A preferred embodiment (30) uses offset starting positions (44, 48), and a lay in alternate twisted pairs substantially longer than that of adjacent pairs, becoming shorter to minimize the nontwisted portion resulting from the time to bring adjacent pairs into planar alignment.  An apparatus for making such cable is also disclosed, having several wire supply twisters (118, 120) and several second twisters (122, 124), removing the twist inserted by the wire supply twisters (118, 120), allowing indefinitely long twisted sections (32, 62, 92).  Twisters (118, 120, 122, 124) are pro-vided in two groups operating in opposite direc-tions, preventing curl of the cable.  The paired conductors are maintained in precisely laterally spaced relationship by heat bonding to thermoplastic film (130, 132).

Abstract: Torque Spring Adjustment Mechanism Abstract Governors for diesel enegines use a torque-spring to control the slope torque-rise curve as the rack actuator moves between the balance point and full load position.  At present, it is difficult to adjust the torque spring mechanism to obtain the correct amount of rack movement between these positions.  A first adjustment screw is engageable with the torque spring, a second adjustment screw is engageable with a fixed stop member, and a means concurrently moves the first screw in spring-deflecting engagement with the torque spring and moves the second screw towards engagement with the stop member in response to fuel-increasing movement of the rack actuator, with further fuel-increasing movement of the rack actuator being prevented by engagement of the second screw with the stop member.

The radiation receiver,  in the presence of smoke in the radiation region,  is impinged by scattered radiation and delivers output pulses.  There is provided an evaluation circuit which generates a blocking pulse, and which inputs a resetting signal to a counter device in consequence of the difference of the blocking pulse and output pulse of the radiation receiver.  The counter or counting device, in the absence of a resetting signal, is switched further and upon reaching a predetermined counter state triggers an alarm signal.  High-frequency electrical disturbances which arise, as long as the radiation source delivers radiation pulses, at most can generate an additional resetting signal for the counter, so that the integrity of the smoke detector against triggering of false alarms is enhanced.  If there is connected in parallel to the radiation receiver a NTC-resistor, then there is obtained a smoke detector which responds to a further combustion criterion (temperature).
