Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for determining the temperature of rail-road car wheel journals (i.e., "hotbox" detector) includes a sensor means including a pyroelectric cell responsive to infrared radiation signals, which are focused onto the cell, to output voltage signals as a function of the radiation signals inputted thereto.  The sensing means exhibits a nonlinear gain response to different frequencies of input signals and comprensation is provided by coupling the out-put of the sensor means to a differentiating circuit which has a similar but relatively negative gain response.  The output of the differentiating means is a substantial voltage replica of the infrared input signal and this voltage signal may be applied to a suitable utilization device such as one which records journal temperature and/or provides a suitable alarm when a sensed journal temperature exceeds a pre-determined  value.

Abstract: Abstract of the Disclosure A method for producing zircaloy tubes from hollows or workpieces which are in the form of tubes having greater wall thickness than the finished tubes.  The method is carried out upon a mill of the general type known as a McKay rocker which has a stationary tapered mandrel, but the mandrel is cylindrical and is moved with the workpiece.  The metal is worked in such a manner as to produce radial grain orientation and fine grain structure.  Close tolerances are maintained on the outside and inside diameters, and the tubes have high strength and ducti-lity.  The grain structure provides increased working life for the zircaloy tubes.

Abstract: IN THE CANADIAN PATENT OFFICE     Title:                        Country Ski Binding Inventers:     Abstract of the Disclosure A cross country ski binding of the type in which a forward-ly extended portion of the sole of a ski shoe is received by and fixed into a chamber fitted to the ski. In the present arrangement an over center linkage is arranged generally in front of the chamber and includes a clamp portion with a hooked end which fits over the top of the chamber and engages an abutment on the upper side of the extended sole portion so that on engaging the binding by actuation of the over center linkage the hook is pulled forwardly to secure the ski shoe within the binding. An especial feature of the arrangement is that the clamp is arranged as a resilient spring which obviates the need for resilience elsewhere in the binding. Actuating means are provided which allow the skier to open and close the binding from a standing position with a ski pole.  In a modification an auxiliary spring fastened to the clamp is used to assist disengagement of the hooked end of the clamp.

Abstract: Abstract A plurality of programming bits are placed into a parallel in-serially out register.  When the programmer is activated, a monostable resets a counter, and energizes an oscillator which clocks the counter.  Three subintervals from the counter are utilized for pulse width modulation of the programing signals.  Once for each bit, the output is energized and begins transmitting pulses at the lowest subinterval rate. Depending upon the logic state of each bit, the transmission pulse is terminated either at the second or the third sub-interval time.

Abstract: ABSTRACT OF THE DISCLOSURE         An open end slide fastener comprises a pair of string-er tapes each carrying along one longitudinal edge a row of coupling elements and a pair of end stop lugs, each of the coupling elements including a pair of spaced legs and a coupling head extending therebetween.  The coupling head has a pair of lateral projections extending longitudinally of the row of coupling elements beyond the width of the legs.          The lateral projections of the coupling heads of the opposed endmost coupling elements located next to the top end stop lugs are cut off to permit the endmost coupling elements to be disengaged from each other when the fastener is closed.  The legs of one endmost coupling element are partly cut off to define a slot extending transveresely of the rows of coupling elements.  The invention thus permits the endmost coupling elements to move unobstructedly toward and away from each other, to improve the smoothness of the movement of the slider within the region of the end stop lugs.

Abstract: Abstract of the Disclosure The device is primarily adapted for use in hospitals and comprises a housing having a front window through which a digital display of sensed temperature is observed. The housing may receive one of preferably two probe holsters one of which has associated therewith a probe for oral use and the other of which has a probe for rectal use. Each probe holster is elongated in shape and has a passage for receiving a probe with the probe being fixedly wired into the holster so that the probe cannot be swapped between  holsters. A holder is mounted on the top of the device and receives a cartridge of probe covers which are locked into the holder but are easily removed upon insertion of the probe into an individual cover. The holsters and associated probes are constructed to be autocalvable and gas sterilizable. The device is normally stored on a platform through which the batteries in the device are recharged between use of the device. The probe is of improved design and employs a thermistor sensor. The probe construction provides improved response time in sens-ing temperatures. The device of the present invention may be operated in essentially two different modes. For normal use the device is operable for a predetermined period of time to detect a peak temperature sensed at the end of the time period. In an alternate mode of operation the device can b operated continuously with continuous updating of the temperature sensed.

Abstract: ABSTRACT OF THE DISCLOSURE Instead of usual chains or belts with protrusions interlocking drive sprockets or gears of positive drive means such as a bucket conveyor, the invention utilizes cables or ropes,  one on each side of the buckets.  The drive is effected by drive pulleys, each pulley guiding   and  driving only a single cable and having a smooth peripheral groove engaging the surface of the respective cable so that the drive is solely frictional,  without any positive interlock between the drive pulley and the cables, while transverse guidance of each cable is also secured, thus rendering the conveyor lighter, less expensive and capable of operating at higher speed to increase operational capacity of the conveyor.  The securement of each bucket to the respective cable is effected by a loop formed by deflecting the cable away from the direction of its pull.
