Title: Improvements in or relating to wheel forks for motor cycles, cycles and the like
IPC: B62K25/16
Filed: 1924-09-06
Abstract: 231,747. Campion Cycle Co., Ltd., and Markham, H. Sept. 6, 1924. Forks of the pivotally - mounted type for motor and other cycles consist of two main tubes or bars 1, each of which is provided with front and rear angularlyarranged strengthening stays 7, secured to the ends of the tubes 1 and spaced therefrom by struts 4. The stays 7 are passed through the bored ends 4<a> of the struts 4, and their lower ends are screwed into transverse plugs inserted in tubular bosses 6, the upper ends being secured in slotted lugs 5 by nuts 9. The stays 7 are clamped in the ends 4<a> of the struts by means of eye or hook bolts, the shanks of which receive nuts 11. The rear stays 7 may be brought closer together at the top to withstand lateral stresses. In the case of a link-mounted spring fork, lateral spacing-tubes 2, 3 accommodate the link spindles.

Abstract: 680,742. Removing dust in industrial processes. ABINGTON TEXTILE MACHINERY WORKS. Aug. 25, 1950 [Nov. 23, 1949], No. 21075/50. Class 8 (ii) [Also in Group XXX] An apparatus for selectively transferring material such as noils and short fibres from a plurality of stations e.g. five pairs of combing machines 1, 2 to 9, 10, Figs 1, 2, into corresponding receivers 20-24, equipped with air exhaust means e.g.. a motor driven pump 25 and a filter receiver 28, comprises conduits 14, 16-19 between each station and its corresponding receiver and a rotary value member e.g., a plate 35 interposed in said conduits and having ports whereby each station communicates with the corresponding receiver sequentially. The valve plate 35 is mounted between two spaced parallel ported plates 33, 34, Fig. 79, each having fine aligned ports receiving the conduits 14, 16-19, and being equally spaced about a central shaft 36 about which the rotary plate 35 having diametrically opposed ports 37, 37a is rotated by a motor 43 through gearing 38, 39. 41, 42. With the port 37 allowing full through flow in say conduit 14, the remaining conduits are blocked by the plate 35, and on moving the plate so as to open the adjacent conduit 17 the port 37a passes across the aligned ports in plates 33, 34 corresponding to the conduit 18, and thus serves to maintain constant the degree of vacuum in the receivers.

Title: Improvements relating to electrically driven clocks
IPC: G04C13/04
Filed: 1933-07-27
Abstract: 421,746. Electric clocks; electric switches. GENT & CO., Ltd., St. Saviour's Road (East), and SWIFT, R., 17, The Circle, Crown Hills, both in Leicester. July 27, 1933, Nos. 21153/33 and 16813/34. [Class 139] [See also Group XXXVII] A master clock controlling a number of secondary clocks is operated by a synchronous motor and the contacts controlling the circuit to the secondary clocks are operated through a pivotal lever coacting with a cam surface on a member carrying one of the contacts. A direct current motor is also provided to drive the master clock when the alternating current supply fails. The alternating and direct current motors and their control arrangements are similar to those described in Specification 421,744. Switch mechanism.-The contacts 34, 35, for closing the circuit to the secondary clocks 36, Fig. 2, are carried by pivotal members 37, 38, biassed by springs 42, 48, to abut normally against stops 41, 47, respectively. The member 37 carries a cam surface 46 having a metal insert of the material known under the Registered Trade Mark " Oilite," which coacts with a foldable latch 26 pivoted at 27 to the end of a lever 17 pivoted at 18. Periodically the lever 17 is lifted gradually by a snail cam 16 driven (through a " lost motion " connection) by the motor and then rocked downwardly to a stop 22 by a spring 23. During the downward movement of lever 17 the latch 26 engages the cam surface 46 to close contacts 34, 35. Also, a weighted bar 51, freely rotatable about the pivot 18 and which normally abuts against a pin 55 on an arm 20 rigid with lever 17, receives an impulse therefrom and is rocked to the position shown in Fig. 3. On its return, the bar 51 strikes the pin 55, causing the latch 26 to fold against the bias of a leaf spring 31, whereupon the spring 42 rapidly separates the contacts 34, 35. A condenser may be connected across the contacts and the period during which they are closed may be regulated by varying the loading of the bar 51. As described in Specification 421,744, when the alternating current supply fails, an armature 63 falls away from the A.C. magnet 5, Fig. 4, the pivotal lever 62 carrying the armature rocking to close at 57 the circuit of the D.C. motor, the average speed of which is made equal to that of the synchronous motor by adjusting the vibration period of the leaf spring contact 57 and adjusting a resistance 56. Should the A.C. supply become available again, then since the magnet 5 is not powerful enough to attract the armature 63, the master clock is driven by both motors until the lever 17 falls to close contacts 34, 35, when a pin 66 on the extension arm 20 rocks lever 62 through pin 65 to the normal position, where it is held by magnet 5. The change over is thus effected when the load on the D.C. motor is light. According to the first Provisional Specification the weighted arm 51 is assisted in its rebound by a leaf spring, and the synchronous motor may be as described in Specification 385,457.

Abstract: 1,066,223. Helicopters. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. May 21, 1965 [May 29, 1964], No.22347/64. Heading B7W. A helicopter rotor has circular section blades on which lift is induced by boundary layer blowing and two independent cyclic controls are provided which act by varying the air flow, using valves (22, Fig.1, not shown) in fixed ports (21) arranged regularly around the rotor shaft and over which sweep ports (17) leading to the blowing ducts of the rotor blades. The valves are actuated through push-rods (25) by a non-rotating swashplate (32) tiltable for the first cyclic control and containing tappets (31) movable relative to the swashplate to effect the second cyclic control. Each tappet is connected to a piston (30) which forms a telemotor with another piston (47, Fig.3 not shown) movable by a second swashplate (42) tilted manually by a spider (41) and handle (40). The second swashplate may be replaced by a cam, and the tappets by electrical actuators which, for example, adjust the lengths of the pushrods by a screw-thread adjustment. The valves may alternatively be individually adjusted under computer control. The blades may be hinged, as described in Specifications 944, 010 and 948, 947, so that they may be stopped and retracted in flight, and are driven by tip nozzles supplied through ducts (15, 12).
