Abstract: ABSTRACT There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of card-iac stimulating pulses.  The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis. The pulse generator further includes means for signaling the acceptance of a pro-gramming signal, and means to reset the program acceptance circuit if extran-eous signals are detected as programming signals.  The program signal accept-ance circuit performs several different checks on the detected programming signal including a parity check, an access code check and determining if the proper number of signals were transmitted within a given time.  The timing circuit of the pulse generator includes a crystal clock oscillator and count-er means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.

Abstract: A B S T R A C T           This invention deals with a retractable tonneau top which is suitable for use on the open-bed of a truck, trailer or wagon.  This tonneau top comprises a piece of covering material which is carried by a stationary bow structure, a movable bow structure and a plurality of intermediate bow structures which are located between the stationary and movable bow structures.  The movable and intermediate bow structures laterally move along a pair of tracks which are attached to the opposing side walls of the open-bed.  Movement of the top is controlled by means of a crank.  Rotational movement of this crank is simultaneously imparted to a drive chain associated with each track.  Each of these drive chains is in turn coupled with the movable bow structure such that the movable bow structure is capable of moving in combination therewith.  Movement of the drive chains in one direction causes the tonneau top to move from a retracted position to an extended position while movement of the drive chains in the opposite direction causes the top to move from the extended position to the retracted position.

Abstract: ABSTRACT of the disclosure The invention introduces an apparatus and a method whereby most of the enticing fragrances and aromas of foodstuffs, like coffe, for instance, which otherwise, by the methods employed heretofore, escaped during roasting and/or grinding, can be used and mixed or absorbed in the drink.  This object is achieved by roasting, grinding and infusing the coffee in the same container (basket), i.e. without transferring the roasted coffee beans to another work-station for grinding, and by the fact that the hot water and/or steam, while dropping down from the top of the vessel surrounding the basket, gets in touch with the fragrances and aromas developed during roasting and grinding, mixes with them and absorbs some or most of them.  This feat is achieved through the apparatus which features a heatable basket for hard and/or soft foodstuff and a rotating blade to ensure a uniform roast.  When the beans are roasted, the heating of the basket is switched off and the blade is rotated at higher speed whereby the roasted stuff is ground.  At the same time water is heated and the hot water and/or steam is lead to the top of the (practically ) closed unit from where, while dropping,  the water and/or steam mixes with and absorbs the aromas and fragrances, reaching the basket and its contents, leaches the grind and, through perforations on the basket, drips to the bottom of the vessel.

Abstract: Abstract of the Disclosure A box spring assembly which includes a generally rectangular frame, a plurality of upwardly extending wire springs mounted on the frame, and a wire grid supported on the upper ends of the springs so that the grid and springs cooperate to yieldably resist downwardly directed bedding loads.  Each of the springs has a body comprised of two side-by-side arcuate portions formed integral at their upper ends with torsion bars that are connected by a connecting bar located between the arcuate portions.  The arcuate body portions thus resist bedding loads with bending stresses and without any areas of stress concentration that would cause early spring failure.  The torsion bars in each spring divide the spring load and resist bedding loads principally with torsional stresses, the combination of both bending and torsional stresses in the springs enabling increased load-resisting capabilities in the springs with a resulting efficient use of spring wire material.
