Title: Improvements in and relating to temperature control systems for continuous kilns
IPC: F27D19/00
Filed: 1952-11-01
Abstract: 747,553. Automatic temperature control systems. MEAKIN, Ltd., J. & G., and TAYLOR, L. Jan. 4, 1954 [Nov. 1, 1952], No. 27531/52. Drawings to Specification. Class 38 (4). In order to maintain constant temperature in a tunnel oven for pottery, a thermocouplecontrolled thermostatic switch responsive to temperature in the oven controls thermallyoperated relays to switch on and off a threephase motor driving cars carrying articles to be fired through the oven. In a modification the driving motor is supplied intermittently by virtue of a continuously operating bimetallic thermal switch below the desired oven temperature, and is supplied continuously by virtue of the thermostatic switch when the oven temperature is above the desired value. Use of a two-speed driving motor without the continuously operating thermal switch is referred to. In another modification one or other of two continuously operating thermal switches is selected by the thermostatic switch so that below the desired oven temperature the driving motor is operated at one average rate while above the desired oven temperature the driving motor operates at a higher average rate. In a final modification a pneumatic controller adjusts, in proportion to oven temperature, the setting of a continuously operating thermal switch interrupting the supply to the driving motor so that the average speed of the latter is dependent on oven temperature.

Abstract: 164,659. Gatwood, W., and Willans, G. H. Sept. 30, 1920. Draw-gear.-In draw-gear of the type described in Specifications 7271/01 and 1481/13, the drawbar cradles are manufactured from rolled metal sections, the webs of which have portions cut away so that when the sections are placed together the necessary working space for the drawspring is provided, the remaining web portions being so formed as to provide at the ends of the cradles the abutments to which the pull of the draw-bar is transmitted. The central portion of the web 1 enclosed between the lines 4, 5 is cut out and from it circular portions 9 each having a central hole 11, are obtained. The semicircular end pieces 6 which are left on are pressed up at right-angles during the process of forming the recess 8 for the draw-bar. The two channel sections are then placed back to back and riveted together at 3. Each of the circular plates 9 is then riveted to the plates 6 to form end abutments for the springs. In a modification, the channel sections are placed with their flanges 2 facing one another, the end pieces 6 being rectangular and projecting in the same direction as the flanges. In assembling, these end pieces overlap and are either riveted or welded to the end abutment plates. Instead of plates 6, 9 being used for the spring abutments, a flange having lugs may be riveted or welded to the webs.

Title: Improvements in or relating to apparatus for phase modulating electric oscillations
Inventor: BRYDEN JOSEPH EASTO
IPC: H03C3/40
Filed: 1952-11-07
Abstract: 745,908. Phase modulation. GENERAL ELECTRIC CO., Ltd. Nov. 9. 1953 [Nov. 7, 1952], No. 28125/52. Class 40 (5). Phase modulation is obtained by vectorially adding in adding means 1 a carrier input and a phase displaced carrier obtained from the output of the adding means through a 90 degrees phaseshifting network 5 and a balanced amplitude modulator 6 whose output is therefore a carrier with amplitude proportional to the modulating voltage. The output and added carrier being in phase quadrature, the phase deviation of the output is therefore sin<SP>-1</SP> x, where x is the ratio of modulation voltage to carrier input amplitude. The phase-modulated output, amplified and restored in a limiter 8 to the same amplitude of the carrier input, then further has vectorially added to it in adding means 3 a quadrature phase carrier from the balanced modulator attenuated to <SP>3</SP>#2 times the carrier input amplitude. The final phase deviation is therefore #=sin<SP>-1</SP> <SP>3</SP>#2.x+tan<SP>-1</SP> x and it is shown that # is linearly related to x except only for fifth and higher powers of it.

Abstract: 276,533. Benton & Stone, Ltd., and Milner, C. E. Nov. 17, 1926. Actuating by air pressure. - A lubricating pump is actuated, or pressure is applied to a piston in a lubricant reservoir, by means of a coaxially-arranged piston operating in a cylinder connected at one end to the induction pipe of a motor-vehicle engine and at the other end to the atmosphere. A p u m p plunger a drawing lubricant into a cylinder in through a pipe q and discharging it through a pipe n is connected by a rod b to a piston c arranged in a cylinder d, the outer end of which is in communication with the atmosphere through a vent s. At the inner end of the cylinder d, a valve f is connected by a hollow stem i to another valve j arranged within a perforated press-button g which is slidable on the stem i. Springs l, k normally maintain the valve j closed and the perforations in the button g open. On depressing the button, the perforations therein are first closed, cutting off communication between the cylinder and the atmosphere, and the valve f is then opened, providing communication through a connection e between the cylinder and the engine induction pipe, the suction in which effects the discharge stroke of the pump. On releasing the button, the valve f closes and communication with the atmosphere is restored, and a spring p effects the suction stroke of the pump. Alternatively, the arrangement may be such that the engine suction is caused to effect both the discharge and suction strokes.
