Title: Improvements in or relating to planetary gear clutches
IPC: F16H1/28
Filed: 1959-01-02
Abstract: 897,432. Toothed gearing; gearing for stopping and starting machinery; securing flywheels on shafts; shaft couplings. U.S. INDUSTRIES Inc. Jan. 2, 1959 [July 7, 1958], No. 169/59. Classes 80 (1) and 80 (2). [Also in Group XXXIV] A disconnectible geared drive between a flywheel 8 and a driven shaft 7 connected to a press &c. comprises a multi-disc brake 82 normally engaged by the bias of springs 97 acting on a pressure-plate 87 so that a hub 59 integral with the driven shaft is held stationary, supplying compressed air to a cylinder 110 sliding a ring-shaped piston 111 therein leftwards of the Figure so that levers 118 are pivoted about their fulcra 101 to slide a pressurering 105 leftwards, pins 107 abutting the pressure-ring 105 thereby being slidden leftwards to move the pressure-plate 87 leftwards against the bias of the springs 97 to disengage the multidisc brake 82, the pressure-ring 105 simultaneously engaging a multi-disc brake 74 which stations a ring-gear 64 so that drive is transmitted from the flywheel through a shaft 6 formed integrally with a sun-gear 55, to planet pinions 56 rotating on the flange 59 and to the driven shaft 7. A ball 42 lies between the ends of the two shafts 6, 7. Cooling and lubricating oil for the discs of the two brakes is supplied through a pipe 129 by a force-feed system and drips down over the brakes &c. to a sump having an outlet 139. The flywheel 8 is secured to the shaft 6 by axial splines 31 and locking-bolts 33 passing through an end-plate 32. The driven shaft 7 is connected to the press through a shaft coupling comprising an internally-toothed sleeve 50 engaging axial splines 47 on a hub splined to the shaft and secured thereon by bolts 45 passing through an end-plate 44.

Title: Device for intensifying hydraulic pressure
IPC: B25B1/18
Filed: 1962-01-02
Abstract: 955,888. Machine tool details. E. M. TOROSSIAN. Jan. 2, 1962 [April 10, 1961], No. 187/62. Heading B3B. [Also in Division F1] A fluid-operated servomotor for moving the jaw 23, Fig. 2, of a machine tool vice, mandrel or clamp, comprises a low-pressure piston 30 in a low-pressure cylinder 27, and a highpressure piston 33 which is responsive to the movement of the low-pressure piston and through which a plunger or like member 32 carried by the low-pressure piston is adapted to extend into a high-pressure cylinder 34. The pistons 30, 33 are axially slidable in the cylinder 27 which is formed by the skirt of a piston 25 on which the jaw 23 is slidable against a spring 24. Low-pressure air supplied through an inlet 29 acts on the piston 30 to exert force on a spring 39 and move the piston 33 to the left, displacing hydraulic fluid from a chamber 34 through a passage 35 in piston 25 into a chamber 26 to move the jaw 23 until it engages a workpiece abutting a fixed jaw. Continued supply of air causes the piston 30 to compress the spring which acts on piston 33 to increase the pressure in the chambers 34, 26, the continued movement of piston 30 then causing the plunger 32 to extend from piston 33 and enter the passage 35 so that the plunger effects an intensified pressure in the chamber 26 to increase the force exerted by the jaw 23 on the workpiece. In an alternative embodiment, the piston 25, Fig. 6, is slidable in a cylinder 44 and attached by a sleeve 42 to a pull-rod 40, ports 46 in the sleeve connecting chamber 26 to the passage 35. Air supplied through the inlet 29 displaces piston 30 and, by way of spring 39, the piston 33 to discharge hydraulic fluid from chamber 34 through passage 35 into chamber 26 to move piston 25 and hence the pull-rod 40 to the right. As the rod engages a load, the movement of the piston 30 cause the spring 39 and piston 33 to apply increased pressure to the fluid in chamber 26 until the plunger 32 enters the passage 35 to provide an intensified pressure in chamber 26 to increase the force applied by the rod 40.

Title: Character recognition apparatus
IPC: G06K9/20
Filed: 1971-01-04
Abstract: 1277705 Character recognition NATIONAL CASH REGISTER CO 4 Jan 1971 [19 Jan 1970] 226/71 Heading G4R A character recognition system includes a tapped delay line fed with the character signal, the taps feeding a recognition unit. The system includes circuitry associated with additional taps on the line for determining when the character signal is correctly positioned in the line, the recognition unit then being triggered. This operation avoids the premature operation of the recognition unit in response to ink splatter or document edges that could result in incorrect recognition. As described the character is sensed magnetically, the character signal passing via a top cut filter to a tapped delay line. The line has taps T1-T8 with extra taps T7-1/3, T7-2/3 between T7 and T8. Taps T1-T8 are connected to a recognition unit. Taps T7, T7-1/3, and T7-2/3 feed diode unit 56, Fig. 2, which delivers a signal, e.g. A, Fig. 3A, equal to the instantaneous maximum of the three inputs. Tap T8 which delivers the most delayed signal B, Fig. 3B, feeds inverter 54. The currents i1, i2 in the resistors forming unit 68 depend on the voltages delivered by the diode unit 56 and inverter 54. Amplifier 70 gives a high output when i2>i1 ; by choice of the resistor values this occurs when the voltage B at tap 8 exceeds 0À65 of the instantaneous maximum A from unit 56. The output of amplifier 70 is inverted at 74 providing a signal, Fig. 3C, to NAND gate 76. This gate is also fed by a signal, Fig. 3B, from unit 87 which is low whenever the voltage 3B at tap 8 exceeds a certain level. The NAND gate output, Fig. 3D, triggers monostable 80 which enables the recognition unit for a short period, Fig. 3E, during which the recognition unit provides an output indicative of the character.

Filed: 1973-01-03
Abstract: 1415041 Burner control circuits KOEHRING CO 3 Jan 1973 [11 Jan 1972] 347/73 Heading F4T A control circuit for a burner comprises leads 1, 2 for connection to an electrical power source and to electrical power consuming components of the burner, e.g. ignition transformer 4 and fuel pump and air fan motor 3, a heat sensitive circuit breaker 7 having breaker contacts 8 in lead 1 and means 9 for opening contacts 8, a thyristor 12 (triac or SCR) connected to the tripping means 9 and operatively associated with a variable resistance type flame detector 15 so that contacts 8 remain closed during normal burner operation and are opened by the tripping means 9, actuated by the thyristor 12, which is triggered by a device 18 having a defined firing voltage, under predetermined abnormal burner conditions. On starting motor 3 and transformer 4 are energized initially but detector 15 has a high resistance so that thyristor 12 is triggered to energize a heating coil 9 which will open contacts 8 unless ignition is effected within a given period, e.g. 15 seconds, the decrease in resistance of detector 15 on ignition rendering thyristor non-conductive. The detector 15 may be a temperature sensitive resistor or a cadmium sulphide photo-conductive cell and the device 18 may be a neon tube, a diac or a Zener diode. The inclusion of device 18 renders the circuit insensitive to flame flicker. The circuit will open contacts 8 on non-ignition, flame shift due to improper burning, or flame extinction. The circuit may include a switch which opens in response to too high a temperature in a combustion chamber in which the burner is located.

Filed: 1919-01-06
Abstract: 126,940. Soc. L'Air Liquide, (Soc. Anon. pour l'Etude et l'Exploitation des procÚdÚs G. Claude). May 15, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Hot-gas engines.-In a closed-circuit engine, which may work with a mixture of nitrogen and carbon dioxide obtained by combustion, the gas is admitted at the ordinary temperature to a compression cylinder C, from which it passes at high pressure through a heater E and a superheater S to a power cylinder D. The exhaust from the cylinder D passes around the tubes of the heater E and through a water cooler R to the cylinder C. The tubes of the superheater S are heated by an external source, the hot gases from which also pass around the heater E before escaping. The compressor and power pistons are mounted on a single piston-rod, and are heavy in order to equalize the driving effort. The cylinders are double-acting, the power cylinder having valvegear similar to that of a steam-engine. The compression and expansion may take place in two or more stages with a water cooler between the compression stages and a superheater between the expansion stages. In order to make up for leakage, gas may be pumped into the circuit by a small compressor actuated from the driving-shaft.

Abstract: 1,067,701. Lamp failure alarms. BRAD. VILLE Ltd. April 4, 1966 [Jan. 5, 1966], No. 460/66. Heading G4N. The state of a set of lights connected in parallel, e.g. the side and rear lights of a vehicle, is checked by means of a bi-metallic strip 6 connected in series with the lights. Strip 6 is connected to a shutter 9. When current from the set of lights is normal bi-metallic strip 6 warms up and moves shutter 9 to prevent light from a lamp 4 passing through a window 2 but allowing it to be reflected from a mirror 5 through a window 3. When the current is below the normal value due to one or more of the lights being inoperative, shutter 9 will not be moved sufficiently to prevent light from passing through window 2. In a modification, Fig. 2 (not shown), a mirror (24) is pivotally connected to and movable with bimetallic strip (6) to reflect light from an indicating lamp and optical condenser (21) through a window (3) when current from the set of lights is at a normal value or through a window (2) when one or more of the lights is inoperative. A shorting switch 10 may be provided for isolating bi-metallic strip 6. Failure of a vehicle brake stop lights may be detected by an indicating lamp (14), Fig. 4 (not shown), which lights up only when both stop lights are operative.

Filed: 1928-01-06
Abstract: 283,181. I. G. Farbenindustrie Akt.- Ges. Jan. 6, 1927, [Convention date]. Cellulose carboxylates and processes of making solutions thereof.-Cellulose esters of the higher fatty acids, which are soluble in the ordinary organic solvents, are made by carrying out the reaction between untreated cellulose and a chloride of a higher fatty-acid in the presence of pyridine, quinoline, or like base, at a temperature above 100‹ C., generally at 100-140‹ or even higher. The temperature varies with the different acids; thus, with lauric acid, it is 110‹ C., and with stearic acid, 140‹ C. The reaction may be conducted in the presence of a solvent for the ester. The reaction mixture is preferably heated as rapidly as possible. For an example, into a mixture of xylene and stearyl chloride is introduced pyridine and cellulose, and the mixture heated to 135-140‹ C., while stirring; the cellulose goes into solution, and the ester is precipitated by alcohol; the product, a di-stearate, is soluble in aromatic hydrocarbons and in chlorinated hydrocarbons. Specification 201.510 is referred to.

Abstract: 562,108. Distilling metals. CHUBB, W. F., and CHUBB, E. P. Jan. 13, 1943, No. 663. [Class 82 (i)] In a process for condensing metallic vapour, the vapour is caused to mix with vapour from the same metal boiling at low pressure and is directed against a cooled surface upon which it condenses. The process may be employed for the separation, either wholly or in part, of vaporized metals of different boiling points. Apparatus for carrying out the process comprises a container a in which metal is vaporized at low pressure, above which is a condensing surface e provided with a jacket e<2> which may contain a refrigerating coil, or through which may flow a cooling medium. The jacket may also contain a coil through which flows a different cooling-medium, so that by adjusting the temperatures of the two cooling-media any desired temperature may be produced at the condensing surface e. Vapour from the metal boiling in the container a rises through a funnel g and is forced by an overhanging cap hand baffle g<1> into admixture with the vapour entering the apparatus through' a jacketed inlet tube i<1>. The metal condensing on the surface e runs down through holes g<2> into the container a and is drawn off through a jacketed outlet pipe b. If desired, an inert gas may be introduced into the vapour through an inlet k, and a pipe l may be provided leading to a vacuum pump. When a mixture of vaporized metals is treated, the metal of lower boiling point is condensed, the vapour of the metal of higher boiling point passes into a trap m. The jacket round the inlet tube i<1> may contain insulating-medium, or may be evacuated, or a cooling medium may flow therethrough; or it may contain electric heaters, or heating gases may flow therethrough.
