Title: Improvements in or relating to clock frequency converters
IPC: H04J3/07
Filed: 1967-04-13
Abstract: 1,129,445. Multiplex pulse code signalling. NIPPON ELECTRIC CO. Ltd. 13 April, 1967 [13 April, 1966], No. 17009/67. Heading H4L. Means are provided for combining two time division multiplex systems having slightly different clock frequencies by controlling a variable delay introduced into the incoming signals. As described, incoming P.C.M. signals p are supplied via terminal 11 and control a clock pulse generator 12 providing pulses a at the bit frequency which are supplied to AND gates 221 and 222. The output clock pulses b are also supplied to AND gate 221 and via a half-bit delay 223 to AND gate 222 and AND gate 23 supplying the output signal p<SP>1</SP> to terminal 24. The input P.C.M. signal is also supplied to a tapped delay line 13 (or a shift register) for sequentially storing each bit of the incoming signal, the five outputs being connected to a rotary switch 14 driven by means 14D. In operation, and assuming that the movable contact of switch 14 is on contact 144, when the clock pulses a and b become in phase, the AND gate 221 provides an output c which sets a bi-stable device 224 to generate a pulse d. The driving means does not respond to pulse d but a switch 15 is changed over to contact 152 to insert a half-bit delay 16 into the output circuit for the retimed P.C.M. signal. Subsequently the clock pulses a and b<SP>1</SP> become in phase and AND gate 222 provides an output c<SP>1</SP> which resets the bi-stable circuit 224 and the movable contact of switch 14 is moved to contact 145 to reduce the delay and switch 15 is changed over to contact 151. The next time pulses a and b<SP>1</SP> become in phase the switch 14 is moved to contact 141 during the period occupied by five clock pulses. It is stated that this period may be utilized for the frame synchronization signal.

Title: A system for thermostatically controlling the delivery of heat to an enclosed space
IPC: G05D23/275
Filed: 1944-09-11
Abstract: 595,364. Automatic control systems. VAPOR CAR HEATING CO., Inc. Sept. 11, 1944, No. 17342. Convention date, Sept. 3, 1943. [Class 38 (iv)] Temperature.-In a system for thermostatically controlling the operation of an electrically energized device for controlling the delivery of heating medium to a means for supplying heat to an enclosed space, a plurality of thermostats are connected in series with each other and with the device, each being responsive to changes of temperature at a different location, whereby all of the thermostats cooperate to close this main circuit and any of the thermostats may operate directly to break said circuit and in a parallel circuit an auxiliary heater is provided for at least one of the thermostats, this thermostat being caused to " cycle " or close its contacts intermittently by a reactor connected between the main and parallel circuits at a point between the thermostat and the said device. As shown applied to the heating of a railway car, air is passed into a compartment through a heater 15 by means of a blower 14. A supply of heating medium to the heater 15 is controlled by a valve 18 which may be closed by a solenoid 22 connected in series with two thermostats 23, 24, the former responsive to the compartment temperature and the latter responsive to outside temperature. The thermostat 23 is provided with an auxiliary heater 33 which supplies the thermostat with extra heat as determined by a variable resistance 35 when both thermostats are closed. Four degrees of extra heat are added to thermostat 23, when any of the two thermostats are open, by a resistor connection 38. The outside thermostat 24 is also provided with an auxiliary heater 39 and resistor 40 which supplies 70 degrees of extra heat to the thermostat 24 when its contacts are open. The thermostat 23 opens when the temperature of the compartment drops below a desired temperature, causing the valve 18 to be opened and increasing the heat supply, the heater 33 causing the thermostat contact to be made or broken intermittently until the room reaches the required temperature. The outside thermostat cycles in a similar manner when its contacts are broken due to a drop in outside temperature, the heater 39 operating only when the inside thermostat is closed. In a modification, the outside thermostat is connected in series between the compartment 'thermostat and the valve-operating solenoid which may be substituted by any form of working resistance such as a heating coil. In a further modification, the outside thermostat is dispensed with and thermostats are mounted in separate compartments in conjunction with passenger-operated auxiliary heaters, a thermostat being provided adjacent to the heater 15 to prevent it freezing. In this case, the thermostat heaters are in series and are provided with a common cycle resistor.

Abstract: 928,331. Diversity systems. NIPPON ELECTRIC CO. Ltd. May 12, 1961 [May 16, 1960], No. 17486/61. Class 40 (5). Relates to a frequency or phase modulation diversity reception system of the type in which automatic phase control circuits enable the respective intermediate frequency channels to be combined before detection. As shown, the incoming signals after frequency-changing at 8 to 11, respectively, are supplied via respective I.F. amplifiers 16 to 19 and buffer amplifiers 29 to 32 to a common output circuit and demodulator 28. Each channel is provided with a phase detector 33 to 36 which receives as one input the common output signal and as the other input the output of its corresponding I.F. amplifier, the resulting control signal being utilized to control the phase of the local oscillator 12 to 15 appropriate to that channel. The common output signal is amplified at 41 to provide common A.G.C. for the I.F. amplifiers. Monitor units 37 to 40 connected to the respective phase detectors operate a relay when a strong beat frequency is produced indicating a faulty receiving unit and block the corresponding buffer amplifier. The system is compared with a known system in which the phase relation of pairs of diversity channels is corrected and after combination a further phase correction and combination is made of pairs of the combined channels and so on.
