Abstract: ABSTRACT      A relay drive and monitor circuit for selectively energiz-ing relay coils in response to input control signals and providing digitally coded output signals indicative of the operation of the relay drive circuit.  A pair of transistors are used in series in each relay coil current circuit and are separately turned on to establish a coil current circuit. The monitoring of the operation of the transistors is based on the comparing of a selected voltage for various transistor operating combination with each of a plurality of predetermined reference signal.  Each reference signal is compared by a corresponding switching comparator with the selected voltage to produce a combined pattern of digital signal levels at the comparator outputs.

Abstract: IMPROVED PROCESS FOR EXPANDING TOBACCO                 Abstract of the Disclosure This invention relates broadly to an improved process for expanding tobacco and involves certain modifica-tions of the basic process for expanding tobacco comprising the steps of (1) contacting the tobacco with liquid carbon dioxide to impregnate the tobacco with the liquid carbon dioxide, (2) subjecting the liquid carbon dioxide-impregnated tobacco to conditions such that the liquid carbon dioxide is converted to solid carbon dioxide and (3) thereafter subjecting the solid carbon dioxide-containing tobacco to conditions whereby the solid carbon dioxide is vaporized to cause expansion of the tobacco.  The present invention pertains, in one embodiment, to an improvement in the basic process which involves controlling the moisture content of the tobacco which is employed in the first step of the basic process.  A second embodiment of the present invention involves draining off excess liquid carbon dioxide, under controlled conditions, after the first step of the basic process and prior to the second step of the basic process.          The present invention pertains, in a third embodiment, to an improvement which involves controlling the output moisture of the product which is recovered from the third step of the basic process.  The present invention further relates to various combinations of the three embodiments set forth above and to an overall process which employs all three embodiments in a manner which permits exceptionally advan-tageous results.

Abstract: ABSTRACT         A protective refractory member which protects heat absorptive elements such as pipe in a furnace comprises two parts connected at their respective longitudinal edges to form a peripherally continuous hollow member.  Both parts include a reticulated metal structure solidly embedded with-in a castable refractory matrix.  In one of the parts the reticulated metal structure extends outward from each longi-tudinal edge to form two closed loops.  The other part has associated with it a clip connected to the reticulated metal structure.  The clip is partially embedded within the part and has hook-like projections, preferably two or more, ex-tending outward from the longitudinal edge which engage the closed loops of the other part to form the hollow protective member.  The hook-like connection can also be used to form protective members having discontinuous peripheries.

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: 6488      INVENTOR:  ERWIN TRESCH          CAN           INVENTION:   SMOKE DETECTOR     ABSTRACT OF THE DISCLOSURE     A smoke detector containing a radiation source operating in a pulsed mode and a scattered radiation re-ceiver connected in a coincidence circuit.  This circuit contains  a counter which counts both the radiation pulses and the incoming scattered radiation pulses.  With undis-turbed operation this counter, following each radiation pulse, has an even numbered counter state. The appearance of an uneven numbered counter state is indicative of the presence of spurious pulses and leads to resetting of the counter to null, so that there is prevented attainment of a counter state adequate for tripping an alarm signal.         On the other hand, with the presence of a predetermined even  numbered counter state there is triggered an alarm.         Such smoke detector is almost immune to spurious pulses and does not tend to trigger faulty alarm signals.  Its operational reliability is appreciably improved.  It is especially suitable for use as a fire alarm or detector.

In such apparatus, a grate and upstanding side plates form a channel for carrying the material along. Each side plate has along its inner face a bench for holding the material to be treated.  As the treatment of material effects changes in the volume of the material, the material tends to lose contact with the side wall, but, by resting on the bench, a seal is provided to prevent direct passage of gases through the bed in the sidewall sections.

Abstract: ABSTRACT OF THE DISCLOSURE      A joint for connecting a partial dental prosthesis to remaining natural teeth has a compression spring (1) acting on joint portions (1, 7) displaceable in a sagital direction, which spring relieves the prosthesis (13) connected to one of the joint portions (7) in the unstressed state.   The displacement of the joint portions when the prosthesis is stressed is delimited by the stop surfaces (14, 15) in such a manner that the spring (10) cannot be completely compressed.   This protects the spring and its functional capacity is permanently ensured and an optimal distribution of the biting and chewing pressure acting on the prosthesis over the anchor tooth (3) and the gums (6) is also attained.
