Abstract: MONITORING CIRCUIT               ABSTRACT OF THE DISCLOSURE         A monitoring circuit for digital circuits is dis-closed.  The monitor is primarily applicable to digital circuits which operate in a cyclic mode with the digital patterns generated during each cycle being repeated in a predictable manner.  A predetermined number of expected bit patterns are stored in a programmable memory.  The stored bit patterns correspond on a bit-by-bit basis to the bit patterns generated by the circuit being monitored when this circuit is operating normally.  In the self-scan mode each pattern generated by the circuit being monitored is compared to each of the patterns stored in the memory in a sequential manner.  Each time a pattern generated by the circuit being monitored is found to identically correspond to a pattern stored in the memory a valid pattern pulse is generated which steps a down counter one count.  If this pro-cess does not result in the down counter being stepped the expected number of times during the operating cycle, a flip-flop is set indicating that the circuit being monitored has malfunctioned.  Provisions are also included for counting the transitions of a digital signal during predetermined portions of the cycle of the circuit being monitored and for monitoring the polarity and amplitude of a predetermined number of analog voltages.  The result of all of these tests are com-bined to generate a signal indicating the operational status of the circuit being monitored.  The monitoring circuit may also be operated in a one-to-one correspondence mode.  In this mode each bit pattern generated by the circuit being monitored are compared to bit patterns  stored in a selected memory location.  If these bit patterns are not identical, a malfunction signal is generated.

Abstract: Abstract An exercising machine includes a pair of inclined guide tracks on each of which a foot-supporting member is arranged to slide frictionally, and the foot-supporting members are interconnected by an elongate flexible ten-sion-bearing element, specifically a flat strap, which slides frictionally over stationary guides.  The machine allows a user to simulate the exercise obtained while climbing stairs: the user stands with one foot on each foot-supporting member, and, by shifting his weight from one foot to the other, causes the foot-supporting  members to rise and fall alternately, with the work done by the user being dissipated by the friction between the strap and the stationary guides.  The use of a friction arrangement in which the rub-bing surfaces are biased together by the user's weight gives the novel re-sult that the frictional resistance is automatically increased for heavier users.

Abstract: ELEVATOR CONTROL APPARATUS            ABSTRACT OF THE DISCLOSURE          An elevator car control apparatus is disclosed in which a three-phase AC tachometer generator is coupled to a motor for driving an elevator car, and the AC output of the tachometer generator is full-wave rectified for use as a speed feedback voltage.  A waveform-shaping circuit generates one pulse for each cycle of the output of the AC tachometer generator.  A counter counts such pulses after the car has passed a deceleration-initiating point, thereby producing the number of counts proportional to a car running distance after the passage of the deceleration-initiating point.  From this number of counts, a decelera-tion command voltage decreasing progressively in accordance with car positions is obtained by a decoder and a digital-analog converter.  During deceleration, the car-drive motor is subjected to feedback control in accordance with the difference between the speed feedback voltage and the deceleration command voltage, thus effecting deceleration control of the elevator car.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosed process for making cast vegetable/mineral structural products having flame retardant properties utilise a major volume portion of ligneus plant fragments such as soft-and hardwoods, sugarcane, cereal and fiber plant stalks, and a minor volume proportion of a mineral binder deposit comprised of magnesium or calcium oxyphosphates and inert filler particles. Fragments having thicknesses ranging from 0.3 mm to 8mm including chips, shavings, strips, strands, fibre bundles, slivers, fibres and peeled and sawn veneer sheets, have applied to their surfaces an aqueous solution of ammonium p   phosphate or soluble acid phosphate salt supplying from 0.15 to 0.40 parts of P2O5 as phosphate ion per part of fragments by weight, and particulate cement solids comprised of MgO or CaO or Mg(OH)2 or Ca(OH)2 or MgCO3 or CaCO3 ranging from 0.25 to 1.0 part per part of fragment, and from 0.01 to 0.80 parts of inert filler particles and the mixture is molded and held under predetermined compaction pressure until the product has rigidified, in about 10 minutes' time.  Greater flame retardation results when the phosphate solution is mainly absorbed into the fragment surfaces before the cement solids are dusted onto the wet surfaces.  At low compaction pressures the product has low bulk density and an open structure.  Use of MgO of density 2.8 or higher of -100 to +250 mesh size and ammonium polyphosphates of analysis 10:34:00 or 11:37:00 with air-dry or oven-dry fragments in amount sufficient to retain on drying impregnated salt loads up to 65 milligrams per cc of ligneus material obtains strong, highly fire-retardant product.   The process is practically immune to cement poisoning sugars and polyphenolics which were found to be detrimental to other cement mixes.

Abstract: ABSTRACT OF THE DISCLOSURE A continuous process for making alkyl alclosides from poly-saccharides and more particularly mixed alkyl glycosides from starch by direct alcoholysis. A polysaccharide, such as starch, is slurried in an alcohol and passed through a heated, confined zone under pressure in the presence of an acid catalyst to form a mixed alkyl aldoside. The alcohols which may be used include methanol, ethanol, propanol and butanol, their isomers and mixtures thereof. Higher alkyl glycosides are surfactants and, in some instances, it is advantageous to use higher alcohols, such as decyl and dodecyl alcohols, to obtain particular sur-factant properties in the resulting alkyl glycosides. Mixed alkyl gly-cosides are useful in detergent applications, and as backbone polymers in polyurethane foams.
