IPC: A63B57/00
Filed: 1927-08-12
Abstract: 296,877. Hart, T. H. Aug. 12,1927. Golf cups for holes.-In a device for ejecting balls from the holes used in ball-putting games, the ball-receiving receptacle used for lining the hole is provided with a pivoted base so that a ball resting on one end of the base can be ejected by pressure applied to the other end of the base by a putting club, walking stick, or the like. A disc-like base c is pivoted on a spindle e within the liner b and the extent of the pivotal movement is limited by a cross-piece f. A hole may be formed in the base to permit the insertion into the ground of the usual flag post. The entrance of a ball depresses one side of the base as shown bv broken lines; to eject the ball the opposite side of the base is depressed sharply by means of a putting club or walking stick.

IPC: H02P9/30
Filed: 1956-07-10
Abstract: 832,066. Automatic voltage control systems. WARD, E. E., and SABAH, N. H. July 2, 1957 [July 10, 1956], No. 21281/56. Class 38 (4). The output voltage of a self-excited generator is controlled by a transistor in series with the field winding. The generator may be either an A.C. or a D.C. generator, and may form the exciter of a controlled alternator. The field winding of the exciter is connected across the armature through the transistor T1. The base of the transistor is connected to a potential divider R2, R3 across the armature. The values of R2 and R3 are chosen from criteria discussed in the Specification. The emitter/ base voltage is controlled by a second transistor T2 in turn controlled by an undisclosed voltage error detector responsive to the output voltage of the alternator. If the generator is used to supply an external load instead of as an exciter, the voltage error detector is connected across the load.

Abstract: 796,282. Moulds for concrete units. CONCRETE, Ltd., and WOOD, K. M. Aug. 4, 1954 [Aug. 4, 1953], No. 21461/53. Class 87(2). [Also in Group X] A mould for casting concrete units comprises smooth pressed steel plates smoothly joined together end to end and lateral partitions locatable within the mould to separate it into sections, the plates having in cross-section the shape desired for the cast units and having no sudden changes in contour or other irregularity in the parts corresponding to the normally visible parts of the cast units. The plates have a cross-section as shown for example in Fig. 2, and two or more moulds are arranged side by side on a floor or vibrating table and joined by wedge-shaped shutters 16. Similar shutters 17 are placed on the outside walls so that the upper edges of the moulds are defined by the shutters. The former shown in Fig. 2, with two U-shaped depressions 14 joined by a raised part 15, is for casting arched roofing units, but other shapes may be cast, e.g., plain flat planks with slightly bevelled edges. Reinforcing wires 18 are stretched along the lengths of the depressions 14, passing through the partitions. After the concrete has set the wires are released at one end and the tension in them causes the castings to slide along the moulds and makes their removal easy. Concrete is poured in to the level of the tops of the shutters 16, 17 which are afterwards removed to leave grouting grooves in the cast unit.

IPC: D01D5/08
Filed: 1957-07-16
Abstract: In a process for the manufacture of filamentary structures which comprises melt-spinning a macromolecular synthetic linear polymer into a plurality of filaments which are extruded through one or more spinnerets substantially vertically downwards and wound up by conventional means, the filaments are caused to glide tangentially or nearly so, through a convex aqueous surface or meniscus, whereat they become to a greater or lesser degree immersed and converge into and form one or more clusters and are quenched whereby they become united or are sintered together where they touch in the form of a composite cluster, or composite clusters.  The convex aqueous surface may be produced by causing water to exude from one or more narrow horizontal slits, the or each horizontal slit preferably having its concavity facing the filaments.  The filaments, as they pass downwards may be urged against the or each horizontal slit by an air blast, the or each horizontal slit being preferably offset from a position directly below the extrusion point towards the filaments and source of air. Specified polymers are polyamides e.g. polyhexamethylene adipamide and polyesters e.g. polyethylene terephthalate. Filaments of differing denier may be sintered together.  The clusters of filaments may take the form of ribbons or yarns. Examples are given.

Abstract: 738,590. Change-speed gear. HOBBS TRANSMISSION, Ltd. Aug. 20, 1953 [Sept. 9, 1952,] No. 22607/52. Class 80 (2). A planetary gear comprises input suns 56, 57, selectively or simultaneously driven by disc clutches A, B; three reaction disc brakes C, D, E for respectively the sun 57, a third sun 58 and either the planet-carrier 64, as shown, or an additional ring-gear (see below), and triple stepped planets,-two 65, 66 of which mesh directly the suns 58, 57, whilst the third 67 meshes the sun 56 through a planet, 68 on a separate spindle, the last-named planet 68 being operatively connected to a final output shaft 60. As shown, this last connection is by a smaller planet-step 69 meshing an output sun 61. In Fig. 4, not shown, the planet 67 directly meshes an output ring gear, whilst in Fig. 5, not shown, the planet-carrier is secured to the output shaft and a brakeable ring-gear meshes the planet 68, in both these cases the planet step 69 being omitted. As shown, in all four forward speeds the sun 56 is clutched to input 10 at A, the additional connections being as follows. First speed (ratio 3.42), carrier 64 braked at E; second (ratio 1.99), sun 59 braked at D; third (ratio 1.39), sun 57 braked at C; fourth, sun 57 clutched to input at B, which, with clutch A gives solid drive. Reverse is by clutch B to drive sun 57, and brake E for carrier 64, (ratio - 5.16). The brakes and clutches are of the usual disc-type (reverse and first brake E having two discs), engaged through insulator plates and flexible diaphragms by hydraulic pressure supplied by an inputdriven pump 71 under control of manual and automatic selector-valves as described in Specification 738,588. The clutch feeds have local exhaust valves 31. Upshift is torque-overlapped, and downshift torque-interrupted to allow time'for engine-speed increase. The Provisional Specification shows also input and output driven oil pumps supplying the pressure system and describes further modifications as follows. Two steps of a triple-stepped planet mesh directly an output sun and a sun clutchable to the input alternatively with a third sun meshed by the third step through a stepped planet on a separate spindle. This yields direct-drive third and overdrive fourth speeds. In another form both planet spindles have only two steps, and a reaction ring-gear is provided. The fluid system includes centrifugal starting valves, pressure-responsive local exhaust valves and restrictor valves in the brake-supply lines variably controlled mechanically by the ratio-selecting distributer-valve to give more rapid flow for upshift than for down, and through fluid pressure by means which increases the restriction at higher speeds and changes it with engine-throttle opening. The ducts used to fill the brakes may be separate from those used for emptying them and may have different flow-areas which may be dimensioned to give torque-overlap. Accumulators may be provided.
