Patent GB-240425-A (GB)
IPC: H04R1/02
Filed: 1925-08-27
Abstract: 240,425. Bothe, O. Sept. 26, 1924, [Convention date]. Loud-speakers; magnetic instruments; diaphragms.-In a loud-speaker in which a diaphragm 19 arranged to move always parallel to itself carries a coil 21 in the field of a magnet,. the current variations supplied to the coil 21 are superposed upon direct current so that the diaphragm always experiences a pull in one direction, which pull is counterbalanced by the elasticity of the air beneath the diaphragm. The size of the air space and the strength of the direct current are chosen so that the reduction of amplitude due to the damping of the air space falls with increase of frequency in the same degree as the impedance of the coil rises. The central conical portion of the diaphragm is formed of two thicknesses of celluloid or bakelitized paper with a softer layer such as tissue paper between them. The natural frequency of the diaphragm is preferably below the audible range. The wires 22, 23 leading to the coil 21 are secured to the shoes 24, 25 on the underside of the diaphragm rim 17 so that the connections are not disturbed when the diaphragm is removed. Connections are led from the shoes, 24, 25 to terminals 32. The whole instrument may be placed in a casing 33, across the aperture in which is a perforated plate 35.

Abstract: 1,260,536. Freezing liquids. FMC CORP. 28 April, 1969 [6 May, 1968], No. 21506/69. Heading F4H. In a continuous freezing machine having a row of moulds moved by a conveyer through the machine a semi-circular extractor pin C is positioned at each end of each mould and when the pins and frozen product are raised from each mould the pins are rotated through 180 degrees to release the product which falls on to a further conveyer. Each pin has a semi-circular head at its lower end which retains the defrosted product during movement out of the mould, until the pins are rotated. The machine comprises an endless chain 28 carrying moulds B on intermittently driven sprockets 24, 26 the moulds passing beneath a mould filler 30, through an insulated brine tank 32, to a slab (i.e. frozen product) handling zone K and finally to washing and sterilizing stations H, J respectively. At zone K Fig. 6 a defrosting tank 69 of hot water is raised to surround each mould in succession. Gripping means engages the pins C and raises them together with the product clear of the mould. A pusher frame 160, moved horizontally by a rack 174a shifts the pins and product along a guide track (170, Fig. 9) where a twisting yoke (92, Fig. 10) grips the pins C and turns them through 180 degrees thereby releasing the product E which falls on to the further conveyer DC. The various movements of the machine are effected by pneumatic circuits operating piston and cylinder devices through valves, certain valves being arranged to be tripped at the end of the movement of one part of the machine to ensure that one movement cannot commence until the previous movement has been completed. An actuator 27 indexes the conveyer 28 by a ratchet 29. A pneumatically driven rack 140a raises the defrost tank. A pneumatic cylinder 120 drives a rack 106 to raise the product from the tank 69 and cylinder and piston means 190, 238, rotate a gear 180a and a further gear (232, Fig. 11) respectively to traverse the product horizontally and to rotate the pins.

Title: Calendar clock
IPC: G04B19/243
Filed: 1926-09-01
Abstract: 281,385. Reid, R. N. Sept. 1, 1926. Calendars.-In a clockcontrolled calendar an independent clockwork motor is employed to drive simultaneously one or more flexible strips bearing indications of the days of the month, days of the week, and the months, the indications being visible through an aperture or apertures in the face of the clock. As shown in Figs. 2 and 3, three separate strips 10, 11, 12 are provided; the strip 10 has the days of the months for a year printed and passes from a take-off spool 13 around guide rollers 15, 16, 17 and a sprocket roller 18 to a receiving spool 14. The strip 11 with the day names is in the form of an endless band passing around a roller 21, guide rollers 23, and sprocket roller 22, and the strip 12 with the month names repeated in accordance with the number of days in the various months is led from a take-off spool 24 around guide rollers 25, 26 and a sprocket roller 27 to a receiving spool 28. The sprocket rollers 18, 22, and 27 have teeth for engaging perforations in one or both edges of the strips, and they are mounted on a shaft 31 adapted to be driven by the shaft 33 of a spring motor 34. The motor 34 is under the control of the clock. and is released once per day by means of a pin 36 on a pinion 35 driven from the hour spindle of the clock. The pin 36 co-operates with an arm 37 of a bell crank lever 38, and in its movement raises the arm 38 which, at the same time, through a link 45 raises a drop arm 44 to free its end from a stop pin 40 on a flywheel 41 and its projection from a notched disc 43. The flywheel is rotated by a pinion 42 until arrested by a projection 39 on the arm 38, which upon further movement of the arm 37 frees the pin 40 and permits the flywheel 41 and notched disc 43 to rotate until the projection on the drop arm 44 enters the succeeding notch and the stop pin is arrested by the end of the drop arm. The sprocket rollers are frictionally driven from the spindle 31 by the intervention of compression springs 45 between the sprockets and collars 46 on the spindle, and bevel gears are connected to the sprockets 18, 27 through shafts 51, 52 to effect adjustment of the strips 10, 12. The receiving spools 14, 28 are secured to a shaft 20 driven by bevel gearing 55 from the spindle 31, and the rewinding of the strips at the end of a year is effected by crank handles 66, 67 operatively connected through clutch devices and bevel gear with the spindle of the take-off spools 13, 24. Instead of bevel gear 55 the receiving spools 14, 28 may be driven by chain gear from sprocket wheels secured to the resetting bevel wheels 47, 48. The spindle 31 may as a modification drive the sprocket wheels 38 through clutch members 69, Fig. 6, normally engaging but disengageable against the action of springs 71 to allow resetting. Pressure rollers may be fitted to keep the strips in engagement with the sprocket drums 18, 27.

Title: A method of and apparatus for the analogue measurement of the speed of rotation of a rotating body
IPC: G01P3/49
Filed: 1962-06-04
Abstract: 1,004,681. Measuring angular speed electrically. SIEMENS-SCHUCKERTWERKE A.G. June 4, 1962 [June 2, 1961], No.21568/62. Heading G1N. Apparatus for measuring the angular speed of a shaft comprises a disc rotating with the shaft in the field of a stationary magnet, whereby eddy currents are induced in the disc and measured by the secondary magnetic field they produce. In one embodiment (Figs. 1, 3), a metal disc 4 is driven by a shaft 5 to cut the field of a permanent magnet 1 whose magnetic circuit is completed by cores 6, 7 separated by a Hall plate generator 8. The change in flux, indicated by the change in output volts from generator 8, is indicative of the angular speed of the shaft 5. The basic flux produced by the magnet 1 is sensed by a further Hall plate generator 11 in separate shunt magnetic members 9,10, unaffected by the eddy current field, so that the difference between the outputs from generators 8,11 is indicative of shaft speed. Alternatively the second generator 11 may be subjected to an independent, controlled magnetic flux, or the output from generator 8 may be opposed by a preset voltage representing the output from generator 8 when shaft 5 is stationary. Automatic temperature compensation is achieved by a magnetic shunt whose permeability varies with temperature in a compensating manner, or by controlling the control current of the Hall plate generators appropriately. In another embodiment (Figs. 4, 5)the eddy currents induced in a rotating disc 15 by a magnet 12 produce auxiliary flux in perpendicularly located cores 18,19 separated by a Hall plate generator 20, whose output is indicative of the angular speed of disc 15 and shaft 16. The magnet 12 may be a permanent magnet or energized by windings 13, 14 carrying the control current of generator 20, which can be varied for different speed ranges. In a modification, a winding 21 on core 18 can be energized to neutralize the auxiliary flux, as shown by zero output from generator 20, the neutralizing current being a measurer of the angular velocity of disc 15. Further embodiments are shown utilising measurement of the auxiliary flux in balanced arrangements where the main flux is neutralized. The Hall plate generators may alternatively comprise magnetic resistive elements. The rotated disc may be shaped as a hollow cone, cylinder or sphere, and may be provided with special short-circuiting rings for the eddy currents. Specification 1,004,682 is referred to.
