Filed: 1963-06-25
Abstract: 982,169. Automatic frequency control. CANADIAN WESTINGHOUSE CO. Ltd. June 25, 1963 [June 29, 1962], No. 25286/63. Heading H3A. In an automatic frequency control circuit for a klystron oscillator 17 from which simulated target pulses are derived for testing a radar system, a frequency disricminator to which the radar transmitter signal and the oscillator signal are applied and comprising two waveguides 6, 9, both adjustable in length and a balanced mixer 12, is continuously automatically adjusted so that its centre frequency coincides with the frequency of the transmitter whilst simultaneously supplying an output signal for controlling the frequency of the oscillator. The transmitter output signal obtained via aerial 3 and cross-coupler 19 is applied via waveguide 4 and cross-coupler 5 to a first adjustable waveguide 6 which supplies one input I to the balanced mixer via crosscoupler 14 and is applied from waveguide 4 via cross-coupler 10 to a second adjustable waveguide 9 one end of which is directly connected to the mixer. The output from the klystron oscillator 17 is applied directly to the circuit via waveguide 4. The discriminator characteristic, Fig. 2, shows that for signals at frequencies below the centre frequency C a positive D.C. output is supplied and for signals above that frequency the D.C. output is negative. The outputs corresponding to the pulsed radar transmitter input and the C.W. klystron input are separated at the output of the mixer. The pulsed output is applied via amplifier 21 and detector 23 to control a servometer 25 which adjusts the length of the waveguides 6, 9 so that the discriminator centre frequency C corresponds to the frequency of the radar transmitter. The D.C. output of the mixer corresponding to the klystron input is applied via D.C. amplifier 22 to the klystron circuit and controls its frequency to the discriminator centre frequency which is the frequency of the radar transmitter.

Filed: 1937-09-18
Abstract: 502,669. Concentrating ores. JORGENSEN, M. VOGEL-. Sept. 18, 1937, No. 25402. [Class 82 (ii)] In the concentration by froth flotation of oxidized ores and particularly of alkaline earth minerals, for example calcium carbonate ores which are to be used in cement manufacture, there is used as a flotation reagent the residue left on distilling the acid oil produced by acidifying soap stock obtained by treating a raw vegetable, animal, or fish oil or fat with a base. The residue contains a certain amount of free acid together with fatty acid glyceride esters. Instead of using the residue itself as a reagent a derivative may be used, e.g. it may be treated, for example, by hydrolysis, saponification, sulphonation, or sulphonation followed by saponification, to convert the glyceride esters into free fatty acids or their derivatives, the treated product being used in the flotation process. The reagents act as collectors and in some cases also as frothers. Oils and fats from which the reagents may bo derived may for example be obtained from soya beans, copra, cotton seeds, peanuts or palm seeds, and whales, herrings, and other fishes. Examples are given of the concentration of limestones, marl, and chalk.

Abstract: 285,937. British Insulated Cables, Ltd., and Wilson, L. B. Oct. 22, 1926. Coin action, mechanical-connection.-In a pre. payment electric meter, the coin-receiving barrel has imparted to it a longitudinal as well as a rotary movement, the longitudinal movement causing the coin to act on another part and make a connection whereby the rotary movement of the barrel is transmitted to mechanism for setting the meter to supply current. The coin is inserted in a slot 4 in a barrel 1, Fig. 1, and, when the barrel is rotated by a handle or key 5, a cam on the barrel engages a stationary cam on a bearing 2 to move the barrel inwardly. The coin engages and moves a plug 7 fixed in a cylinder 8 and having a cross pin 10, which is moved to engage slots 11 in a cylinder 6 thereby coupling and transmitting the rotary motion of an extension 9 of the barrel 1 to the cylinder 6. After half a revolution of the barrel, the coin drops out to a money-box, and the barrel 1 and cylinder 8 are returned by springs 16, 17 respectively. Electricity, supplying by meter.-A toothed wheel 13 on the cylinder 6 actuates meter setting or quantity mechanism of any suitable known kind, such as epicyclic mechanism. The switch, which is closed as soon as the coin inserted is discharged, comprises a bell-crank lever 25, 27. Fig. 3, the arm 25 having a contact head 24 and the arm 27 being connected by a spring 31 to an arm 28, which is pressed by a spring 32 to open the switch, but is retained in switch closing position by a detent 34 pivoted at 35. The arm 28 is engaged by pins 41 on the cylinder 6 but the arm 27 cannot follow the arm 28 until the cylinder 6 has made half a resolution, when a notch 18x in the flange of a disc 18 . releases a pin 27<x> on the arm 27. The cylinder 6 is positioned after each operation, so that the pin 27<x> can pass through the notches 18<x>, by a spring- controlled arm 56 engaging a cam 55. When the quantity of electricity prepaid is consumed, the radial arm of the epicyclic quantity mechanism closes a switch to energize an electro-magnet 38. This attracts an armature 36 on the detent 34 and releases the arm 28. When the maximum number of coins have been inserted, a pin 49 on the radial arm 43<x>, Fig. 6, of the epicyclic mechanism engages an arm 50 and raises a sprag 51 about a pivot 52 into the path of longitudinal movement of the barrel 1. This prevents the barrel from being rotated until some of the electricity prepaid has been consumed.
