Abstract: Abstract An assembly for a pager having a main housing that is generic to a family of pagers having different outputs.  A subassembly housing contains the output circuitry for each member of the family of pagers.  A generic circuit is mounted on a circuit board that is slideable within the main housing between a first and second position.  The circuit board, in a first position, allows the subassembly housing to mate with the main housing.  The subassembly housing is locked into mated engagement with the main housing when the circuit board is slid from its first position to its second position. The locking engagement is provided by a tongue-like projection mounted on the circuit board which is received by a slot in the subassembly housing when the circuit board slides to its second position.  In conjunction with this a flange mounted on the subassembly housing engages a first end of the circuit board.

Abstract: ABSTRACT A device is disclosed for joining metal sheets by a rivetting-type method   The device has a female die and a male die which can be moved in the direction of the female die by means of a press, the sheets being superposed face-to-face between the dies.  The male die comprises a punch provided with cutting edges and the female die comprises counter-edges and an anvil which is set back behind the counter-edges and on which the material forced through the counter-edges by the punch is pressed to flow behind the incision rims, whilst the counter edges yield laterally and, after the joint has been lifted out of the female die, are returned again into their cutting position by means of spring tension.  The counter-edges are formed by the free end rims of leaf springs which are clamped on one side and extend parallel to the movement of the male die.

Abstract: SCHOTTKY SHUNT INTEGRATED INJECTION LOGIC CIRCUIT   James M. Early ABSTRACT      An improved integrated injection logic structure utilizes  a current mirror in conjunction with each switching transistor (M1, M2) of the integrated injection logic circuit of this invention by connecting one of a plurality of collectors (O0, P0) of the switching tran-sistor to the base of said switching transistor.  In this manner, the current flowing through conducting switching transistors is limited by the current mirror.  This limited current flow through conducting switching transistors, as well as the use of voltage pull up means (D1, D2) connected to the collectors of the switching transistors prevents the saturation of conducting switching transistors.  This results in an increase in the voltage on the collectors of conducting switching transistors and a decrease in the voltage swing between a logical one and a logical zero, thereby substantially increasing the speed of the integrated injection logic circuit of this invention as compared to prior art integrated injection logic circuits.  The voltage pull up means connected to the collectors of the switching transistors may comprise resistors or preferably forward biased Schottky diodes connected between a voltage source (Vdd) and the collectors of the switching transistors. This invention is also suitable for use in MOS circuit.

Abstract: ABSTRACT          Disclosed is a method for selectively deactivating catalytically active sites which occur only on the surface of a zeolite of boralite catalyst.  Active sites occurring on the interior of the pores are masked by saturating the catalyst with an organic compound which fills substantially the whole of the catalyst pore volume.  The catalyst so treated is then exposed to a deactivating agent, such as a solution of an alkali metal salt which is substantially immiscible with, substantially insoluble in, and which is otherwise unreactive to said pore-filling compound.  The catalyst is then treated to drive off the pore-filling compound, yielding a catalyst selectively deactivated only on the external surface, but which is not deactivated within the pores.  The treatment enables the catalyst to be used for e.g. hydrocarbon conversion for long time periods without carbon buildups around the pore entrances, which buildup would otherwise either restrict entry into the pores by reactants or exit therefrom by product.

Abstract: HYDROGEN LEAK MONITOR FOR A TURBINE-GENERATOR            Abstract of the Disclosure A device for monitoring the leakage of cooling gas for a turbogenerator stator into the stator water-cooling system is disclosed.  The device is located next to the generator so that the operative elements are at the generator storage tank operating water level.  As cooling gas accumulates in the storage tank together with cooling water, the gas displaces the water in the leak monitor until the water level rises to a predetermined, adjustable level.  When this level is reached, the gas is vented and the water level is restored to equilibrium.          Each cycle is recorded on a leak trip counter.  When the leakage rate exceeds a predetermined value, an alarm is triggered.

Abstract: ABSTRACT       A control system is disclosed for controlling dual-fluid Brayton/Rankine cycle engines over a wide operating range to maintain high efficiency under partial load conditions.          The overall system includes a first control system for the Brayton cycle part and a second control system for the Rankine cycle part of the engine.  The control system follows a control path defined by the locus of peak efficiency points at reduced loads, resulting in a declining inlet temperature of the turbine portion of the engine as the load decreases.          The invention is particularly useful when the engine is used for both work output and steam generation (co-generation).

Abstract: ABSTRACT OF THE DISCLOSURE:         The present invention relates to copolymers which can be employed as bonding agents between polymers and inorganically oxidic material.  They are distinguished by a reactive alkoxysilyl group and an acrylic or methacrylic acid residue.  Each of these two groupings is connected at a fundamental structural unit with two chain C-atoms respec-tively, with this fundamental structural unit being built up on a compound with an ethylenically unsaturated group as monomer.  The ratio of the alkoxysilyl groups to the acrylic or methacrylic acid residues in the new copolymers can assume any desired ratio, for example as a result of the copolymers being copolymerised with further compounds with ethylenically unsaturated groups which do not possess the desired residues. The present invention also relates to a process for the preparation of these new copolymers, as well as intermediate products which are obtained in this preparation as hitherto unknown products.
