Patent GB-1134419-A (GB)
Title: Apparatus for the synchronization of rotational speed
IPC: H02P5/50
Filed: 1966-06-27
Abstract: 1,134,419. Automatic control of speed. TOS KURIM. June 27, 1966 [June 29, 1965], No.28687/66. Heading G3R. To synchronize the speed of rotary members 2, 3,4 with that of a master 1, the output of selsyn transmitters 6, 7, 8 on each slave member is compared with that on the master 5 in differential selsyns 17, 18, 19 which each drive (through a slipping clutch) a control member (21, Fig. 2 not shown) which actuates contactless switches (22, 23) at either extreme of its travel by which speed correcting servomotors 10, 11, 12 are controlled. The switches actuate relays 20 controlling the servomotors and actuation for correction in one sense also charges a capacitor which, when the control member moves away from its end position upon correction taking effect, is discharged into a relay which causes brief operation of the servomotor in the opposite direction; this is to eliminate hunting. Each selsyn 6, 7, 8 may be driven through an adjustable friction drive unit such as 48 which smooths sharp variations in speed. The rotary members 1....4 may be "drive conversion units" driving mechanisms 13....16 in mill or chemical plant.

Title: Lifting apparatus
IPC: B66F7/02
Filed: 1974-06-28
Abstract: 1478512 Elevation-safety control GKN TRANSMISSIONS Ltd 27 June 1975 [28 June 1974] 28728/74 Heading B8L A vehicle lift comprises vehicle support arms secured to carriages vertically movable along pillars 1, 2 under the control of a screw and nut drive mechanism, a sensing means being provided responsive to obstruction to the lowering of the vehicle or carriages, to provide an output signal causing termination of the lowering of the carriages. The screw-threaded rod of one pillar is rotatable by a belt and pulley transmission from an electric motor and the remote end of this threaded rod is in chain and sprocket connection with the rod of the other pillar for simultaneous elevation of the two carriages. Each screw rod is mounted in upper and lower bearings permitting axial upward movement relative to the normal operating position, so that upon a nut being prevented from moving down the rod due to an obstruction to the passage of the vehicle, further rotation of the screw rod causes the rod to rise causing a collar adjustably secured to the rod to operate a micro-switch for de-energizing the electric motor. The motor drive circuit is further provided with bottom and top limit switches, a driving chain break safety switch and overrun safety switches.

IPC: B21D39/02
Filed: 1922-10-23
Abstract: 197,264. Bagley, C. H. F. Oct. 23, 1922. Angular bending.-An apparatus for folding sheets of steel, iron, &c., consists of a table comprising a pair of leaves hinged at their inner ends so as to be rotatable about parallel stationary axes to fold the sheet against a dividing member. The sheet w is placed on a table consisting of a pair of leaves a, b keyed on parallel shafts c, d which are geared together and driven by a rack k reciprocated by an hydraulic ram n so as to fold or double the sheet about a fixed or adjustable dividing plate p suspended from the frame q. A bar r, preferably T-shaped is used to bridge the space between the bosses a<1>, b<1> of the leaves, the bosses being recessed at t, v so as not to foul the bar. The finished sheets are palled off the dividing plate by tongs and may then be flattened.

Title: Improvements in temperature correction devices for gas meters
IPC: G01F3/22
Filed: 1955-10-10
Abstract: 815,906. Counting-apparatus. SANGAMO WESTON Ltd. Oct. 10, 1955 [Oct. 8, 1954], No. 28825/55. Class 106 (1). In a gas meter having a shaft rotated by volumetric measuring apparatus and driving indicating means temperature compensating means is located between the shaft and the indicating means. The shaft 10, Fig. 1, rotated from the meter mechanism 3 at a rate proportional to the rate of gas flow carries a pointer 14 and two pinions 12, 13. The pinion 13 meshes with a gear 21 fixed to the sun-wheel 16 of a differential gear 15. The pinion 12 drives through a gear train 36-42 the input disc of an infinitely-variable gear comprising a disc 46, a ball 47 and a roller 53 which through a worm and worm-gear 56, 57 drives a pinion 60 which meshes with a gear 22 fixed to the other sun-wheel 17 of the differential gear 15. The ball 47 is carried by a shaft 48 the foot 48a of which rides on a cam 52 carried by a shaft 62, the angular position of which is determined by a bi-metallic strip 64 attached thereto. In this way the rotation of the pointer 25 carried by the output shaft 20 of the differential gear 15 is corrected in accordance with temperature changes. The pointer 25 is connected through continuous gearing to the pointers 26, 27. In another example, Fig. 3, the pinion 12 drives a gear 71 having an eccentrically-disposed roller 74, Fig. 4, which effects oscillation of a pivoted gear segment 77, 78. Movement of the gear segment 77 in one direction is taken via a oneway clutch 92, 93, 94 to a gear 86 which through gearing 89, 91, 56, 57, 60 drives the sun-wheel 17 of the differential gear 15, Fig. 3. The gear 77, Fig. 4, has a pin 96 which co-operates with a cam 97 controlled by a bi-metallic strip 64a.

Abstract: 387,293. Starting. PEDROLI, S., Aulnay-la-Riviere, Loiret, France. Oct. 15, 1932, No. 28854. Convention date, Oct. 16, 1931. [Class 7 (v).] To facilitate starting of an internalcombustion engine, fuel, maintained at a constant level in a closed container 18 by a float 19 and valve, is sucked therefrom, together with air drawn in through bubbling tubes 20, along a conduit 21 to a cylinder 27, a piston 29, Fig. 2, which normally closes the orifice of the conduit 21, being withdrawn manually against spring action to expose that orifice and air inlet ports 34 ; the mixture then passes along a pipe 28 to the induction pipe of the engine. The piston 29 may be operated by a lever 33 on the dashboard or by a pin on the piston rod which is rotated to co-operate with notched inclines on the cylinder end. A check valve in a casing 22 in the conduit 21 is lifted by the engine suction and excessive lift is prevented by a gauze screen which also prevents backfiring. In a modified form of cylinder, a piston 42, Fig. 9, has cutaway flanges 46, 47 which compel the mixture, drawn through the conduit 21 past a channelled piston 52 seated on teeth 53, to follow a sinuous path, air being drawn through an aperture 54 between the end wall of the cylinder and a cut-away portion 50 of the piston 42.

Filed: 1922-10-24
Abstract: 201,462. Percival, S., (Wells. C. E., and Llewellyn, H. F.). Oct. 24, 1922. Holders.-In devices for locking lamp bulbs in holders of the kind wherein a shield A surrounds the socket of the holder and extends so that its open end lies in proximity to the glass of the bulb, a spring D being attached to the inside of the shield so as to engage the lamp pins F to prevent the removal of the lamp, the C-shaped spring D is provided with slots E adapted to embrace the pins F so that a lamp cap cannot be removed from the holder until the glass bulb is destroyed. When the bulb is destroyed, a tool G having converging ends provided with open-sided slots can be inserted beneath the springs, as shown in Fig. 6, to release the pins and to hold them while the cap is being removed.

Filed: 1963-07-26
Abstract: <PICT:1014271/C6-C7/1> A magnetic Ni-Co alloy film is deposited directly on to an Al or Al alloy substrate by depositing a layer of Zn on the Al and placing the Zn coated Al into contact with an aqueous Ni-Co-containing solution having a composition effective for depositing a Ni-Co alloy directly on to the Al with simultaneous dissolution of the Zn coating.  The Zn may be deposited from an alkali metal zincate bath which may also contain one of the hydrous oxides of Fe, Co and Ni to aid the deposition. In addition to zincate, one bath contains FeCl3.6H2O and tartrate ions and another contains potassium copper cyanide and sodium sulphite.  An example of a Ni-Co bath contains CoCl2.6H2O, NiCl2.6H2O, Rochelle Salt, NH4Cl and NaH2PO2.H2O.  Ni-Co baths are used at from room temperature to 180  DEG F.  Examples of alloys which may be deposited are 90% Co, 7% Ni, 3% P, and 40% Co, 56% Ni, 4% P depending on the relative concentrations of Ni and Co salts in the baths.  Reference is made to Al storage devices or memory units comprising Al discs or drums coated with a magnetic metal film.
