Title: Improvements in grinding and polishing machines
IPC: B24B17/02
Filed: 1925-07-28
Abstract: 238,533. Kelm & Daniel Ges. Aug. 16, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Disc and wheel apparatus. - In a machine for grinding and polishing metal articles, the blank is mounted on a rotary spindle in a headstock carried in a rocking frame, the headstock being axially reciprocated to carry the work past a stationary grinding-wheel and having also a transverse movement to bring the work up to the grinding-wheel and to withdraw it after the operation. The work spindle 40, provided with an automatic chuck carrying a work piece 45 is mounted in a headstock 42 adapted to rock about a shaft 38 and also to move axially on ways carried by a bed 3. A roller 41 is pressed by spring buffers 43 against a templet 44 so that the work which is reciprocated past a stationary grinding-wheel is given the required profile. In a modification, Fig. 4, for non-circular work, the templet 48 is carried on the work spindle and abuts a stationary roller 49. The work spindle is driven from the main driving-pulley 6 through a clutch operated from a pedal 52 and normally held in against spring pressure by a latch 8. The main shaft 4 drives through gearing 10, 12, a countershaft 11 which is connected through spur-gearing 21, 24, worm gearing 26<1>, vertical shaft 25', and bevel gearing 27. to a horizontal shaft 30 carrying a long pinion 28 from which rotation is transmitted to the work-spindle through gears 36, 39. The headstock is reciprocated axially by means of an adjustable crank-disc 33 driven from the shaft 30 through worm gearing 29 and pinion 31. The bed 3 also receives transverse movement to move the work towards and away from the tools by means of a cam drum 19 which is loose on a shaft 9 and may be driven either at high speed from a pinion 13 engaging a mutilated gear 14 or at low speed by a pin 17 engaging an elongated slot in the drum, and driven by worm gearing from the counter shaft. The chuck may be controlled either mechanically or magnetically so that the work piece 45 is automatically released when the crank disc reaches the end position shown in Fig. 1, the actuation of the chuck being effected by a lever 47 which may engage a suitable abutment or may control a magnetic circuit. In operation, on completion of the axial work traverse for the polishing operation, the gear 14 comes into engagement with the pinion 13 and is rapidly driven to withdraw the work from' the tool, and at the same time the chuck is opened. When the bed 3 is fully withdrawn an arm 50 trips the latch to disengage the clutch and stop the machine while a fresh work piece is positioned. On reengaging the clutch by the pedal 52 the cam drum is further rotated to bring the work piece up to the grinding-wheel. The pinion 13 then runs off the gear 14 and the cam drum remains stationary, until, at the end of the polishing operation, it is again engaged by the pin 17 and slowly rotated thereby until the gear 14 again engages the pinion for the withdrawal movement.

Abstract: 590,828. Speedometers. MAGNESIUM ELECTRON, Ltd., LASCH, L., and WHERRETT, F. D. C. Oct. 6, 1944, No. 19215. [Class 106 (iii)] [Also in Group XXIX] The linear speed of the ram of an extrusion press or other linearly moving part is measured by apparatus comprising a piston and cylinder, one of which is connected mechanically to the moving part, and liquid from one end of the cylinder is passed through a liquid flow meter which indicates the rate of flow of the liquid and hence the speed of the moving part. The piston 19, in its working stroke, Fig. 3, forces liquid up a pipe 27 through a non-return valve 25 and the flowmeter 30 to a tank 22 which feeds the other end of the cylinder. On the return stroke, the right-hand end of the cylinder draws fluid through pipe 27 and non-return valve 24, which is supplied partly from the left-hand end of the cylinder and, to make up for the size of the piston-rod, partly from the tank 22. The flowmeter, Fig. 2, comprises a float 35 which rides in an upflow of liquid in a tapered glass tube 36 at a variable height depending on the rate of flow. When there is no upflow, the float 35 engages a bevelled surface 37 to. act as a non-return valve. In the idle part of the working stroke, a blow-off valve 32 permits fluid to run to the tank without going through the flowmeter.

Abstract: 1420150 Automatic control of temperature GLAVERBEL-MECANIVER 24 April 1973 [28 April 1972] 19302/73 Heading G3R [Also in Divisions H3-5] In a control circuit for an electric heater employing as sensing device a thermistor having a negative temperature coefficient, when the temperature falls the resistance of the thermistor 16 increases reducing the current through the arm-of the circuit containing the thermistor so that transistors 13, 14 across that arm are rendered non-conducting thus causing current to flow to triac 12 and switch it on. With this triac conducting current is fed directly from supply 2 to heater 1. A capacitor 15 keeps the triac continuously conducting. If conversely the temperature rises transistors 13, 14 are rendered conducting by the decrease in resistance of the thermistor 16, and the triac circuit is shortcircuited, the triac is switched off and no current flows to the heater. The circuit is used to control a heated laminated window and may be integrated and encapsulated in resin, and located between the edges of the laminations.
