Title: Improvements in or relating to electrical power supply equipment
Inventor: BECK ARTHUR CECIL
IPC: G05F1/247
Filed: 1955-05-10
Abstract: 787,838. Supply systems for consumption apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 10, 1955, No. 11492/57. Divided out of 787,837. Drawings to Specification. Classes 38 (2) and 38 (4). Electrical power supply equipment for a complex load such as a broadcast radio transmitter comprises an alternating current regulating device of the moving coil type which incorporates driving means for moving the movable coils from a first position to a second position with a slow continuous movement; release means being provided so that the movable coils may move rapidly from the second position to the first; a switch for starting the driving means; direct connections from the regulator to the circuits comprising the load wherein each circuit is provided with an overload relay effective to control the release means. Closure of the starting switch energizes a clutch and an electric motor then slowly drives the movable coils from the first position in which, when a substantially constant voltage is applied to the device, the output voltage thereof is zero to the second position in which the output voltage is a maximum. At this position means such as an astatic relay function to keep the output voltage constant. Should a fault occur or one of the overload relays operate the clutch becomes de-energized, thereby allowing the movable coils to move rapidly from the second position to the first (zero voltage) position, this movement taking place due to the gravitational forces, or the magnetic forces, acting on the coils. Operation of a stop mechanism results in a similar movement of the coils to the zero voltage position. In the embodiment shown, one of the circuits of the complex load has a voltage injected therein by means of an injection transformer so that the voltage applied thereto begins at a value above zero. The regulating device is described and claimed in Specification 787,837 from which Application the present Application has been divided.

Filed: 1920-04-26
Abstract: 143,495. Henry, A. May 19, 1919, [Convention date]. Chair plates; sleepers, securing rails to.-For securing metallic constructional members to reinforced-concrete structures, such as railway rails to sleepers, a curved bolt, passing through a hole formed in the concrete during moulding, is employed in conjunction with clamps to grip the rail &c. The rail is secured to the sleeper by clamps b, d, and a curved bolt which passes through a hole of oval cross-section moulded in the sleeper. The surfaces of the clamps are machined to stand at right-angles to the stem of the bolt. A wooden packing is interposed between the rail and the sleeper. Instead of a headed bolt, nuts may be employed at each end of the bolt. The hole in the sleeper may be lined with a wire coil embedded in the concrete, and a sheet of lead or lubricant may be interposed between the bolt and the wall of the hole.

Title: Improvements in the manufacture of horse shoe nails
IPC: B21G3/28
Filed: 1928-04-25
Abstract: 289,404. Mustad, O., Mustad, C., Mustad, H., Mustad, W., and Mustad, C., (trading as Mustad & Son, 0.). April 26, 1927, [Convention date]. Forging nails.-Horseshoe nails are made by first pressing up the shank on the end of a rod &c. fed automatically to the machine, severing the blank from the rod, carrying the blank to another press in which the shank is subjected to a second pressing operation so as to shorten the tapered part between the shank and the head and finally carrying the blank to a third station where the head is upset. The rod W is fed by the feeding arm 11 to the four-die press 10, which presses up the shank. The blank is then severed and grasped at the position a, Fig. l , by an arm of a four-or-eight armed stepwise rotating carrier 1 and carried to the position h, where it is pressed a second time by four dies arranged in pairs on arms 2 forming parts of levers 3 mounted loosely on pivots 4. The levers 3 are knuckle-jointed to members 6 and are operated by cams 5. The lateral movement of the die carrying arms 2 allows the blank held by the carrier to enter the space between the dies in a lateral direction. During the pressing operation the blank is forced outwards by the dies but is forced back again when the dies move apart by a spring 7 so that it reaches the upsetting position c in correct position relative to the upsetting tool 12. The finished nail is ejected at the position d. Specifications 15096/13, 21657/13 and 113,804 are referred to.

Filed: 1917-08-25
Abstract: 116,612. Main, G. P., and Main, T. Aug. 25, 1917. Vibration-dampers.-A shock-absorber for use on automobiles and for other purposes consists of two parts, one attached to each of the relatively moving parts and having their interengaging faces provided with projections, undulations or cam surfaces held together by means of a spring so that any relative angular motion between the two parts causes a separating movement against the action of the spring, said spring acting to return the parts to their normal positions. Fig. 1 shows an example in which 1 and 2 are the two interengaging portions connected respectively to the chassis and axle shaft by arms 5 and 6. The spring 9 returns them to their normal positions after separation. Reference has been directed by the Comptroller to Specifications 20503/07, 11668/08, 5570/09, 3606/10, 19595/10, and' 4252/11.

Title: Improvements in Governing Internal Combustion Engines.
Inventor: CLARKE CHARLES WARRINGTON EARL
IPC: G05D13/00
Filed: 1918-07-30
Abstract: 118,408. Clarke, C. W. E. Aug. 13, 1917, [Convention date]. Regulating is effected in an engine having two or more inlet and two or more exhaust valves in each cylinder by a series of adjustable cams which control the valves independently either to put one or more of them out of action or to vary their lift in accordance with the power required. As shown in Fig. 2, inlet valves 2, 3 are actuated by cams 9, 10 respectively, mounted upon a shaft 8 which may be adjusted longitudinally. In the extreme left-hand position of the shaft, both valves receive their maximum lift. As the shaft is adjusted towards the right, the valve 3 continues to maintain its maximum opening whilst the opening of the valve 2 decreases progressively until the stem of the valve rests upon the concentric portion a, of the cam 9, when the valve closes. Further movement of the shaft to the right decreases the lift of the valve 3 until the closing position is reached, when the stem of the valve rests upon the concentric portion a of the cam 10. Similar mechanism may be used to actuate the exhaust valves. A throttle valve in the supply pipe may be connected to the mechanism for adjusting the cam-shafts which are located on opposite sides of the engine. A separate carburettor may supply each inlet pipe

Abstract: 755,137. Tyre treads. FIRESTONE TIRE & RUBBER CO. April 29, 1954 [Aug. 21, 1953], No. 12433/54. Class 144 (2). A tyre tread comprises a pair of circumferential parallel zig-zag crown ribs 13, 14, defining a zig-zag groove 17, which are flanked on each side by a series of circumferentially-spaced generally transverse bars 15 or 16 which are inclined to the central plane of the tyre and to the bars of the opposite series so that all the bars are directed in the same circumferential direction to provide a directional tyre. As shown, the ribs 13 and 14 are broken by narrow transverse grooves 18 at the apices nearest the centre line of the tread to form a relatively staggered mutually facing chevron arrangement, the ribs being interconnected at each bend by braces 20 which extend radially from the base of groove 17 to half the rib height, and transversely into the adjacent groove 18. The combined circumferential length of the braces 20 is twenty per cent of the total length of groove 17. The shoulder bars 15, 16 are arcuately inclined from the tread shoulders to adjacent the ribs 13, 14 to which they are attached, across narrow grooves 23, 24, by braces 25, 26 respectively rising from the bottom of the narrow grooves to half the rib and bar height. To provide for uniform vulcanization of the large shoulder-bars 15, 16, and to reduce shock transmission thereby, deep narrow grooves 28 extend into the bars from their axially outer ends to terminate just short of their axially inner ends. The bars 15, 16, which are high at the tyre shoulders, define between adjacent bars and the intervening rib portions valleys 27 that open to the side of the tyre. To reduce noise in use, the bars 15, 16 may be of different circumferential lengths and spacings transversely and circumferentially of the tyre. To avoid trapping of stones in the groove 17, the sides of the groove may each comprise two radially inclined surfaces, converging upon the opposite corresponding surfaces, as shown in Fig. 6.
