Title: Improvements in or relating to pulse generating devices
Inventor: ROBINSON THOMAS EDWARD
IPC: H03K3/78
Filed: 1964-10-15
Abstract: 1,078,916. Pulse circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Oct. 15, 1964, No. 42210/64. Heading H3P. [Also in Division G4] In a system for generating a predetermined number of pulses, particularly for use as a strobe generator in an asynchronous computer, a delay line DPG, a gate G3 and an inverter 15 have regenerative feedback so that when gate G3 is enabled, a train of pulses is generated. Counters LC and BC are provided to inhibit G3 after the generation of the predetermined number of pulses. The Specification describes how predetermined numbers of pulses from 1 to 25 may be generated on line PTO, the number being predetermined by the initial settings of counters LC, BC and by the presence or absence of signals at OC, M. The first pulse may be generated by simultaneous application of voltage steps at ST and OC, initiating a step along delay line DOP. A toggle TOP is set by the first output from DOP and reset by the second output, feeding a pulse via gate GO to output line PTO, the duration of which is determined by the delay between the first and second outputs of DOP. Subsequent pulses are generated by the loop G3, I5, DPG continuously setting and resetting the toggle TPG. Each pulse steps counter BC until all its toggles TA, TB, TC are set, when the setting of counter LC is reduced by one. The counting continues as necessary, until the count in LC has been reduced to zero when a process finish toggle TPF is set, terminating the output of the pulse generating circuit PG. The first pulse generator is inhibited when generating trains of certain predetermined numbers. The OR gates employ diodes feeding a series capacitor.

Filed: 1974-09-30
Abstract: 1479176 Selective signalling MOTOROLA Inc 30 Sept 1974 [12 Oct 1973] 42397/74 Heading G4H A tone signal-detector, for use with a radio paging system receiving station, and which responds to a particular plurality of tone signal frequencies in sequence incorporates a switchable filter 19 incorporating FET switches, each operative in response to a particular control signal to determine the particular frequency which the filter couples through. The tone frequency sequence is applied to the filter from a receiver section 11. A tone detector 20 respohds to the filter output and provides a signal which is applied (via a counter 21) to a coding device 24, which generates a group of binary signals representing the next tone signal in the sequence appropriate to the particular receiving station. The binary group is applied to a decoder 26 to generate a control signal for the appropriate FET switch in the filter 19. The detector operates from a battery 34 and includes a voltage converter 35 such that a voltage in excess of the battery voltage is provided to decoder 26 in order to shift the voltage levels of the binary signals from the coding device 24 to a higher level appropriate to the FET switches. The calling tone signal sequences normally contain five tones. When the counter 21 has counted up to five, an alarm 33 is activated to warn the person called, and the audio amplifier 12 is switched on. The arrangement incorporates a timing circuit 22 which develops a signal a given time after the final count to reset the counter, filter 19 and tone detector.

Title: Method and apparatus for increasing the nutritive value of soybeans
IPC: A23L11/30
Filed: 1967-09-18
Abstract: 1,146,415. Improving the nutritive qualities of soybeans. H. TRUAX. 18 Sept. 1967 [19 Oct., 1966], No. 42411/67. Headings A2Q and A2B] In a method and apparatus for heating soybeans to destroy or deactivate bitter and deleterious constituents, such as anti-trypsins, urease and fat-oxidizing lipoxidase, and thus make the soybeans less susceptible to rancidity and more palatable and nutritious to human beings and livestock, including poultry, the soybeans are cascaded in close proximity to a source of infra-red rays, so that the soybeans are heated by these rays to a temperature at which their skins (teguments) are ruptured by the pressure of vapour generated within the skins, and the resulting soybeans are transferred, without substantial fall in temperature, to a storage bin, in which they are kept until substantially all bitter and deleterious constituents are destroyed or deactivated. In using the apparatus shown in Figs. 1, 2 and 5, soybeans are fed, from a hopper 40 through a shoot 41 and a control gate actuated by an arm 42, into one end of a tiltable trough 11, and are cascaded through the trough to a discharge opening 47, by vanes 32 on a rotating, longitudinally disposed shaft 31. As the soybeans move cascadingly along the trough, they are heated by infra-red rays radiated from a gas-heated, cylindrical, metal grid 26<SP>1</SP>. A reflector 28, and adjustable ventilators 29 and 30 hinged thereto, cover the trough. Each vane 32 is preferably in the form of a wire grid. Fresnel-diffraction and Cornuspiral pulsating effects in the infra-red rays passing through the wire grids produce peak pulses having, for example, an intensity of 40,000 B. Th. U. per hour, per square foot, when each square foot of the radiating surface of the grid 26<SP>1</SP> receives 25,000 B. Th. U. per hour from its associated gas-burner. The temperature of the grid 26<SP>1</SP> may be between 980 and 1,370C. The atmosphere in the trough is preferably maintained at 205C. The heated soybeans pass from the opening 47, through a shoot 48, Fig. 5, to an elevator 49 comprising a tubular casing 52, a rotating auger 51 and a discharge tube 53, through which the heated beans are fed into a storage bin 50, coated internally with heat-insulating, preferably heat-reflecting, plastics material. The bin has an overhanging roof 58, which is separated from the top of the bin by a ventilating space 60, so that any condensate forming on the undersurface of the roof can drip away outside the bin. The heated soybeans may be stored in the bin 50 for 1 to 12 hours, and may then be cooled, as by air from a blower, and discharged through an outlet shoot 56.
