IPC: B23G1/16
Filed: 1930-11-21
Abstract: 361,117. Screwing ; tapping. SOC. INDUSTRIELLE D'APPAREILLAGES M•CANIQUES ET ELECTRIQUES, 74, Rue St-Maur, Paris. Nov. 21, 1930, No. 35130. Convention date, March 6. [Class 83 (iii).] In a portable machine for screwing or tapping, the tool-spindle is driven through a reversing bevelgear drive, controlled by axial pressure on the tool, and a yielding ball clutch from a worm wheel rotated by a flexible shaft. The hollow casing 1 is closed by end caps 2, 3, the former having a handle 17 adjustable on a screwed part 2a thereof and locked by a split 17a and a clamping screw 19. The flexible shaft is attached to a spindle 7 carrying a worm driving the wheel 5 loose on a shaft 4. A disc 8 secured to the worm wheel 5 has recesses 8a engaged by balls 10 located in cylindrical holes 9a in a collar 9 cottered to the shaft 4 at 11. A spring 13 normally maintains the balls 10 in contact with the disc 8 through a washer 12 but allows the drive to slip on overload, the compression of the spring 13 being varied by adjusting the handle 17 and causing a ball 16 therein to move the abutment sleeve 14 of the spring. A bevel gear 21 on the shaft 4 rotates a gear 23 loose on the tool-spindle 24 through idle gears 22 and a collar 25 secured to the spindle 24 is adapted to drive the tool in one direction or the other through dogs 29, 30 thereon engaging similar recesses in the bevel gears 21, 23 respectively. Spring pressed balls 27 normally maintain the collar 25 in the neutral position shown, but axial pressure on the handle 17 causes the tap to be rotated in the appropriate direction by tapping or withdrawal. The spindles and shafts in the machine are mounted in lubricated ball bearings.

Patent GB-192685-A (GB)
IPC: F01K1/04
Filed: 1922-12-28
Abstract: 192,685. Babcock & Wilcox, Ltd., (Assignees of Deutsche Babcock-&-Wilcox Dampfkessel-Werke Akt.-Ges.). Feb. 3, 1922, [Convention date]. Hot-water storage apparatus.-In a steam boiler plant comprising a hot-water storage tank connected to the boiler water and steam spaces, the connection with the boiler steam space is controlled by the boiler water level. The upper part of a storage tank 3, Fig. 1, is connected with a boiler 1 by a pipe 10 opening inside the boiler at the normal water level. When the demand of the consumer 2 falls, the boiler level rises, and water flows through the connection 8 from the boiler to the tank. When the demand rises, the pressure in the tank falls, and steam is supplied to the consumer from the tank, through a pipe 6 fitted with a non-return valve 7. At the same time, to prevent water from flowing from the boiler through the pipe 8 into the tank, a valve 16 in the pipe is adapted to be closed by a spring 15 acting on a piston against the pressure in the pipe 6. In a modification, the pipe 8 is fitted with a cock 24, Figs. 2 and 3, so separated by a float in the boiler that when the water level rises, water may pass from the boiler into the tank, the fresh feed supply being maintained through a port 23, but if the level rises above a certain height, both the feed supply and the supply from the tank are cut off. If the water level falls, the cock is so operated by the float as to cut off the feed supply through the port 23 and allow hot water to flow from the tank into the boiler.

Title: Actuators
IPC: F15B15/18
Filed: 1975-08-27
Abstract: 1524044 Fluid-pressure servomotor systems SPERRY RAND CORP 27 Aug 1975 [4 Oct 1974] 35301/75 Heading G3P A self-contained dual hydraulic actuator  assembly, e.g. for aircraft control surfaces, is formed by combining a pair of actuator assemblies, each generally as described in Specification 1523453, and providing means to divide the load equally between the actuators. The latter comprise a cylinder 12 slidably containing a piston 14 whose rod 16 extends into a second cylinder 12' to connect with second piston 14' whose rod 16' is attached at 22 to an aircraft control surface. Fig. 1 shows one half of the assembly, the other half being illustrated in Fig. 2 (not shown), each half having all the features described in Specification 1523453. In addition the half shown includes a spring centred valve 116 subject at its opposite ends to the pressures in the right-hand ends of the cylinders 12, 12' via lines 26a, b respectively. Should these pressures become unbalanced, valve 116 shifts rightwards to restrict the line 68 between the servovalve 66 and the swash-plate control piston 76, or leftwards to restrict the corresponding line 68' between the other servovalve (66') and control piston. The pressures in the right-hand ends of cylinders 12, 12' are thus maintained balanced. Similarly an identical valve (116') in the other half balances the pressures in the left-hand ends. A further valve 118 is subject at opposite ends to the output pressures of the auxiliary pumps 34, (34') and when either falls to a low value, the valve shifts to connect the righthand end of cylinder 12 or 12' to the other auxiliary pump. Simultaneously the corresponding valve (118') will do the same for the left-hand end. Thus a disabled cylinder is effectively by-passed through the auxiliary pump lines and does not impose a load on the remaining cylinder.

Abstract: 818,781. Automatic frequency and phase control systems. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. July 29, 1957 [Nov. 20, 1956], No. 35406/56. Class 38 (4). An automatic frequency or phase control system is arranged to have rapid " pull-in " time when out of synchronism but slow rate of follow once synchronism is reached. As shown, a diode bridge is gated open by pulses applied at C, D from an oscillation source to be controlled in frequency and phase so that pulses of amplitude dependent on the instantaneous amplitude of a reference source A, B, e.g. mains frequency, passes to an integrating circuit. This first comprises a capacitor C1 in series with a resistance R4 shunted by a pair of oppositely-poled unilaterally conducting devices V1, V2 so biased that they are non-conducting when near synchronism between the oscillation sources is reached. The effective value of the series resistor R1 of the smoothing circuit R1, R3, C2, C3 is therefore large, giving a long time constant, but during out of synchronism the devices V1, V2 are conductive during most of the duty cycle giving R1 to normal effective value and a rapid time constant. The, resistor, R4 may alternatively be connected to the midpoint of the resistor of a parallel R-C network connected between the diodes V1, V2 so that a single source may bias both the diodes. The system may stabilize the frequency and phase of a television synchronizing pulse generator of frequency of twice the line frequency followed by frequency division down to frame frequency to derive the pulses applied at C, D.

Title: Apparatus for clay-treating oils
IPC: C10M175/00
Filed: 1934-12-12
Abstract: <PICT:0447139/III/1> Used lubricating oils are reconditioned by mixing with decolorizing clay, heating, filtering, and submitting to reduced pressure to remove gasolene and other volatiles, in apparatus in which the vacuum and the flow of oil are broken unless the temperature is within certain limits.  For example, crank case oil and clay supplied through a funnel 1 are agitated together in a tank 2 by air from a pipe 6, pump 3, and pipe 5, and are drawn through a pipe 12, a pipe 9 enclosing an electric heater 8, pipes 13, chambers 14, filters 15, chambers 16 and pipes 16<a> to an annular chamber 17, from which the oil flows to a tank 18 and the vaporized substances pass by a pipe 19 to a condenser 20 and an annular tank 21 connected by a pipe 22 to the suction side of the pump 3.  When the apparatus is started by closing an electric switch 38 (1) a magnetic switch 26 closes and current passes through the heater 8 warming the air in the tube 9 and the bulb B of a thermostat 10 which controls an air-inlet solenoid valve 7 on the pipe 5 and immediately causes this valve to open; (2) current passes to the motor operating the pump 3 so that air is drawn through a hand-operated valve 4 and the pipe 5 to the pump and forced through the pipe 6 to agitate the oil-clay mixture in tank 2.  After a few minutes valve 4 is partially closed to a predetermined extent--or is closed completely if a spring-weighted vacuum relief valve is fitted to the pipe 5--and when the bulb B reaches a predetermined temperature the control contacts of the thermostat 10 are opened so that the valve 7 closes; the pump 3 then reduces the pressure in pipe 22, tank 21, and the system generally, causing oil-clay mixture to rise in the pipe 12 and flow through the apparatus.  Should the oil reduce the temperature of the bulb below the determined point valve 7 is opened, the vacuum broken, and the flow stopped until the desired temperature is again attained.  The supply of current to the heater 8 is controlled by a thermostat 23 according to the temperature of the oil about a bulb 28<a>.  The vacuum gauge 24 is provided with an adjustable electrical contacting point 25 so that should the vacuum become so high that the recording needle makes contact with this point the main current is broken and the apparatus ceases to function.  An ordinary thermometer 27 is provided to indicate the temperature about the bulbs B, 28<a> of the thermostats 10, 23.  The filtering is preferably effected through the porous plates described in U.S.A.
