In a radio receiver or transmitter the frequency of an oscillator 1, Fig. 1, is indicated by applying an output from the oscillator to a frequency-to-voltage converter 3, the D.C. output of which is indicated by a meter 4. An amplifier/limiter 2 may be interposed in the output from the oscillator 1, which may comprise the local oscillator of a superheterodyne receiver, the meter 4 being calibrated in terms of the signal frequency. The frequency-tovoltage converter may comprise a differentiating circuit formed by capacitor C1 and diode D, Fig. 2, coupled to the emitter of transistor T, the collector circuit of which comprises an integrating circuit formed by resistor R1 and capacitor C2, followed by filter network R2, C3 feeding terminal 24 to which the meter is connected. The time-constants of the differentiating and integrating circuits may be varied by means of varactor diodes C25, C26 respectively, or by transistor T2 connected across resistor R1. To match the output voltage supplied by the frequency to voltage converter 33, Fig. 3 to a predetermined scale, it is supplied to a differential amplifier 37. The output of an auxiliary oscillator 35 is fed to a second frequency to voltage converter 36 to produce a D.C. reference signal which is a function of the frequency of oscillator 35, and is fed to the second input of differential amplifier 37. The output of this is a measure of the frequency difference between oscillators 31, 35 and it is supplied to the frequency-to-voltage converter 33 to vary one of its time-constants. In a further embodiment in which oscillator 41 feeds via limiter/amplifier 42, which is optional, into frequency-to-voltage converter 43, the output of the converter is compared in differential amplifier 44 with the voltage from a potentiometer comprising resistors R45, R46, R47, derived over switch 49. The output from differential amplifier 44 is applied to a varactor diode (Fig. 5, not shown) in the oscillator 41, so as to bring its frequency to a value selected by the switch 49.

Filed: 1973-05-08
Abstract: 1435720 Monitor circuit; temperature alarms L J M BILLION 8 May 1973 [10 May 1972] 21779/73 Headings G4H and G4N In a circuit for monitoring the positions of switches 14 . . . 20 (normally in positions 24-1 . . . 24-n) a lamp 48 lights to indicate the first switch which changes to position 26. The switches connect an A.C. source 8 to a process control 22: in the event of, e.g. a temperature rise, one of the switches (e.g. 14) changes position to complete a circuit which includes the gate 52-1 of an SCR 50-1 and a switch 56 in position 60. Since switch 56 connects a 5V tapping 64 on a transformer 30 into the circuit, SCR 50 is fired and a lamp 48-1 lights up. A relay 40 is caused to change switch 56 to position 66, thereby by-passing the 5V tapping 64: thus even if another switch subsequently changes position, the corresponding SCR 50 will not be fired and the corresponding lamp cannot be lit. The circuit is reset by means of a switch 38. In another embodiment (Fig. 2, not shown) with switches 14-20 in parallel, the lamp corresponding to an actuated switch is caused to flash on and off, and an alarm horn is sounded. Resetting this circuit causes a flashing lamp to be lit continuously.

Title: Improvements in or relating to the crimping of textile fibres
Inventor: PARKER JOHN
IPC: D02G1/12
Filed: 1962-06-06
Abstract: A tow or sliver of thermoplastic fibres of any cross-section e.g. trilobal, is subjected to the action of steam, preferably wet, at superatmospheric pressure immediately prior to stuffer-box crimping. The fibres may be of a polyamide such as polyhexamethylene adipamide, a polyester such as polyethylene terephthalate, or a crystalline polyolefin such as polypropylene. The tow &c. may be subjected to the steam for a period beyond that sufficient to raise its temperature to the equilibrium temperature of the steam and the steam pressure may be lower than that employed in any subsequent steam-setting process. Crimped tow may be cut into staple fibres.  As described, the fibres emerging from the stuffer-box are collected by coiling into a bag and the full crimp (more than fifteen crimps per inch) is allowed to develop over a period of five hours.  Specification 696,761 is referred to.

Filed: 1925-09-01
Abstract: 254,903. Tauma-Ges., Taubert, A., and Schwartz, J. Sept, 1, 1925. Spray producers; coin action, weight; coindischarging mechanism. - Perfume is delivered in a spray from one of several bottles 4, Fig. 2, through a corresponding nozzle 7, after setting an outside member to connect the particular bottle required to a pneumatic blower 13, by operating an actuating handle 27 of the blower which is released by the insertion of a coin. The handle 27 is locked by a catch 42, Fig. 4, projecting from and pivoted to an arm 30 depending from a counterbalanced coin lever 32. A coin inserted into a bucket 33 on the lever 32 tilts the lever to remove the catch 42 which is turnable in one direction only. The handle 27 is now depressed to actuate the blower and, during its downward movement, actuates the projecting end 40 of a bent wire hook 39 blocking the lower end of the coin bucket. The hook 39 rotates in lugs 41 and allows the coin to drop. In order to prevent a pumping action of the handle 27 to obtain more than the proper quantity of perfume, it travels between two arresting levers 51, 52, Fig. 6, provided with ratchet teeth 53, 54 for preventing upward and downward movement respectively of the arm 27. When a coin is inserted an arm 59 on the balance beam 32 moves the lever 52 out of the path of the handle 27 to allow this to be moved down, the lever 51 ensuring a complete stroke. At the end of its downward movement the handle 27 strikes a bent end 60 of the lever 51 to move this lever against the action of a spring 57 out of the path of the return movement of the handle 27. The lever 51 is held in this position by a pivoted catch 61 until the handle is returned when it lifts the catch and allows the lever 51 to be returned to normal position. Testing coins.-Small coins fall out through side slots in an inclined portion 37 of a shoot which leads the coins to the bucket 33. These small coins fall into a separate receptacle.
