Abstract: ABSTRACT OF THE DISCLOSURE     Priority interrupt apparatus includes a level priority network, a plurality of priority networks, and selector cir-cuits, each corresponding in number to the number of channel sources operative to generate interrupt requests.  Each pri-ority network receives request signals corresponding to dif-ferent types of possible event signals requiring attention and produces a type code designating the highest priority event from the channel associated therewith.  The priority is established in accordance with a preassigned event pri-ority approximating the priorities assignable by program.           Each of the selector circuits is connected to receive as a control input the type code signals generated by the pri-ority network associated therewith.  Additionally, each selector circuit receives a different set of interrupt level number signals representative of priorities assigned by pro-gram to the number of possible event signals.  In response to the request signals, the selector circuit of each channel source applies as an input to the level priority network the programmed designated set of interrupt level number signals specified by the type code signals.  The level priority net-work includes a number of compare circuits and output gating circuits.  Each compare circuits provides signal indications as to which one of a pair of channels has the higher priority event as defined by the selected interrupt level signals.          Signals indicating the results from each compare circuits are then applied to the output gating circuits which gener-ate a code for selecting the type code and interrupt level signals of the channel source receiving the highest priority event.

Abstract: MANUAL STARTER WITH LOW VOLTAGE RELEASE                   Abstract of the Disclosure A manually operated snap acting switch having contacts in a circuit connecting an electric source to an electric load.           The switch has contacts operated by a toggle mechanism and in-cludes elements and mechanisms for causing the levers of the toggle mechanism to move to a tripped position and the contacts of the switch to pen whenever the current in the circuit exceeds a predetermined value or in event of a power failure of the source.  The elements and mechanism causing the movement of the levers to the tripped position and an opening of the circuit in event the source has a power failure include a spring-biased lever, a solenoid, which is continuously energized by the source, and a latch which is moved to released position by the solenoid plunger when the solenoid is de-energized.           The lever which causes the toggle levers to move to the tripped position is held in an inactive position by the latch and moves to an active position when the solenoid is de-energized and the latch is moved to its released position.  The solenoid, latch and spring-biased lever are positioned in a cavity in the base of the switch and the toggle mechanism is arranged so its levers are in the OFF position and the power of the source fails.

Abstract: Abstract of the Disclosure Joint clearance control in brazing is accomplished by incorporating in the brazing composition certain size metal particles, preferably spherical in shape, which substantially maintain their shape at brazing temperature and which at brazing temperature are preferably wettable by the filler metal in the brazing composition.  The brazing composition can be further modified by the inclusion of similar particles of a ductile metal which is not entirely liquid at the brazing temperature, but which is sufficiently soluble in the filler metal at the brazing temperature to alloy incompletely with the filler metal.  This latter modification is useful in brazing together materials of dissimilar expansion and contraction characteristics particularly as a function of temperature.

Abstract: Application of Howard D.W. Hill and John R. Laudermilch for NUCLEAR MAGNETIC RESONANCE SPECTROMETER EMPLOYING AN IMPROVED RESONANCE SIGNAL GATING CIRCUIT              ABSTRACT OF THE DISCLOSURE     In a nuclear magnetic resonance spectrometer a gate is employed for time share multiplexing of the resonance and transmitter signals.  An improved gate circuit is connected in series between the receiver and the resonance detecting circuit employed for picking up resonance of the sample.  The improved gate circuit includes a pair  f parallel connected branches of PIN diodes connected between the input and output terminals of the gate.  The diodes in each parallel branch are poled toward an intermediate control node in such a manner so that a positive control potential applied to the control of one branch node turns that branch on and conversely a negative control potential applied to the other control node turns on the other branch.  Equal magnitude and opposite sign control pulses are applied to the control nodes so that tran-sient switching signals, tending to leak through the gate, cancel on the output line to the RF receiver.

Abstract: ROTARY SEAL             Abstract of the Invention.  The invention is an improved rotary seal which is particularly well suited for protecting the bearing area in a conveyor idler roll.  The seal has inner and outer annular members which normally rotate freely without contact relative to each other.  The members have cooperative means to form a labyrinth effective to restrict the ingress of contaminant or the egress of lubricant to or from the bearing area.  One of the members further includes an attached annular disc of resilient flexible material.  When the lubricant pressure in the bearing area increases, such as when the bearing is being regreased, it forces the free edge of the disc into contact with the other member to form a barrier against the leakage of lubrication.  When the lubricant pressure normalizes, the resilient disc recovers to its normal, noncontact position.                             -1a-

Abstract: DISPOSABLE HYPODERMIC SYRINGE   AND METHOD OF MANUFACTURE            ABSTRACT OF THE DISCLOSURE       The disclosure is of a disposable hypodermic syringe and the method of its manufacture.  The syringe comprises a barrel, a piston plunger slidably mounted in the barrel, a handle and shank connected to the piston-plunger, a needle hub welded to and closing one end of the barrel and supporting a hypodermic needle, a shield for the needle and a cap which closes the other end of the barrel.  A novel feature of the syringe of the invention is a weakened zone of the barrel in a line circumscribing the barrel at a point adjacent to the edge of the needle hub.  An advantage of the syringe of the invention is its disposability after use.  To dispose of the syringe, the operator first replaces the shield over the needle and hub.  The hub with the enclosed needle may then be broken off along the weakened zone of the barrel by bending, so that the barrel is destroyed and the needle is enclosed within the shield and hub in such a manner that it may not be re-used or misused without considerable and extraordinary effort.  The needle hub and barrel form a sealed annular chamber when assembled, which isolates the barrel-hub welding zone from the fluid path of the syringe.  This chamber will trap any flash which may be generated by the welding process.
