Abstract: 1,047,442. Automatic temperature control systems. JOHNSON SERVICE CO. June 27, 1963 [June 29, 1962], No. 25558/63. Heading G3R. An automatic control system for say temperature giving a response on one selected side of a datum comprises a thermistor 18 connected in a bridge circuit 18 giving a reversible phase output which is amplified by transistors 28, 34 and applied to a transistor 38 connected through a rectifier 66 to a load such as an spring loaded normally open expansible fluid actuator. In the summer positions of switch 68 the valve will control the flow of cooling water or air and only below say 75‹F will the thermistor act to cause transistor 38 to conduct and the valve to close proportionately to temperature deviation. In winter the valve will control the flow of hot water or air and with the switch 68 in the W position only temperatures above say 75‹F will operate the valve. The arrangement is temperature stabilized by resistors 44, 60.

Abstract: 1,095,355. Continuous wave radar. DORNIER SYSTEM G.m.b.H. April 29, 1965 [May 22, 1964; Aug. 27, 1964], No. 18088/65. Heading H4D. The Specification describes a radar system whereby a hit or the miss-distance of a missile relative to a target may be detected. Two frequencies differing by for example 5 mc/s. are radiated omnidirectionally from the target and after reflection thereby are received back with corresponding doppler frequency shifts fd, and fd2 (a and b, Fig. 7). These are converted into corresponding square waves c and d by limiters B, Fig. 5, and passed to a digital phase discriminator P. This produces pulse train e, indicating the phase differences between corresponding pulses in trains c and d, which is passed through a gate T, controlled by amplitude threshold means AS, such that it is open only when signals above noise level are being received and by frequency threshold means FS which limits the width of pulses arising from the region of signals a and b, corresponding to the nearest approach of the missile and exhibiting an inaccurate phase reversal, to that shown in pulse train f. Pulse train f is passed through a low-pass filter TP, having a limiting frequency lower than the lowest pulse repetition frequency expected in train f, to produce a mean level output g, the final value of which represents the miss-distance of the missile. This value is stored at SP, the store being cleared at the beginning of the next missile passage. To extend the speed range of the system filter TP may be replaced by three low-pass filters in parallel (Fig. 6, not shown), having pass bands such that low speed, medium speed and high speed missiles are respectively allowed for. To allow fine and coarse miss distance measurements three frequencies may be transmitted, two having a large frequency difference and giving a fine but ambiguous measurement, and another two having a small frequency difference, giving a coarse measurement.

Abstract: 1,225,109. Feeding and delivering sheets. RICOH K.K. 11 Nov., 1969 [22 Nov., 1968], No. 55023/69. Heading B8R. In a machine such as a copying, printing or punching machine wherein sheets are fed into the machine one by one from a pile 23 on a table 27 and are delivered from the machine to a table 12, means are provided whereby adjustment of an end plate 1 on the table 27 to contain definite positions according to the sheet size, causes similar adjustment of an aligning plate 2 on the table 12. The plate 2 is attached to an endless chain 16 which can be driven by a motor 11, and the lower end 2a of the plate can actuate switches 6 ... 10 in a circuit controlling the motor 11 when the chain is driven. The plate 2 is initially situated near the right-hand end of the table 12, and if power is now supplied to the motor, the plate will move leftwardly until the part 2a engages the switch 9 which causes the motor 11 to be reversed and the plate 2 to be moved rightwardly. When the part 2a engages the switch 10, the motor is again reversed, i.e. the plate 2 reciprocates between extreme positions determined by the switches 9, 10. The intermediate switches 6, 7, 8 are in parallel with switches 3, 4, 5, one of the latter being opened by the lower end 1a of the plate 1 when the plate is moved manually rightwardly to a position corresponding to the size of the sheets. If, for example, plate 1 is set so that the switch 3 is opened, then when during movement of the plate 2, its end 2a opens the switch 6, the motor circuit is opened to stop the motor. The position of the plate 2 then corresponds to that of plate 1. Similarly, the operation of switches 4, 7 or 5, 8 causes setting of the plate 2 to positions corresponding to that of the plate 1 when the latter is positioned to open switch 4 or switch 5. A similar arrangement may be provided for aligning plates engaging the side edges of the sheet piles.

Abstract: 1,259,318. Distance measurement. CARL ZEISS JENA VEB. 17 June, 1969, No. 30668/69. Heading H4D. Specification describes an electromagnetic wave distance measuring apparatus including a modulator transmitter M for transmitting a modulated electromagnet wave and a detector/ receiver D which receives the modulated wave after reflection thereof at a distant reflector RE. The detector modulation signal is fed via a circuit of unity loop gain to the control input of the modulator M. The path of the wave and signal thus form a self-oscillating loop, oscillating at a frequency f E  depending on the total length of said path such that: when n is an integer. Part of the total path length is contained in the electronic circuitry and is generally unknown. To overcome this a variable phase shifter F is inserted in the modulation signal path and a short circuiting reflector R K  is provided at a position defining the near limit of the sought distance. With reflector R K  in place a new oscillating loop is produced, resulting in a modulation frequency f k , whereby: c Short circuit distance=n2 - 2fk Delay E is thus adjusted until f E  = f K  =f whereby: Sought distance 2s= Total path length - short circuit distance = (n 1  - n 2 )c/2f 2f A frequency meter Z determines frequencies f E  and f K  and may be calibrated in range.
