IPC: D06F39/12
Abstract: 721,892. Washing-machines. HOOVER, Ltd., and HANDS, C. H. Jan. 22, 1953 [Jan. 30, 1952], No. 2541/52. Class 138 (2). [Also in Groups IV (a) and V] In a washing-machine including an outer easing or skirt joined at its upper edge to a washing liquid container, and extending downwardly towards or -beyond the region of the bottom of the container, the container and the skirt are formed integrally with each other from reinforced moulded thermosetting synthetic resin of a low pressure moulding type, viz. one that can be moulded at a pressure not exceeding 200 1bs. per square inch. The reinforcement may be glass fibre with or without additional fillers. In the example the container is of generally rectangular form having one lower corner edge cut off by a wall sloping from one side to the bottom. The skirt may extend to a level considerably below the bottom of the container to conceal a driving motor housed below the container. The motor drives a rotary disc-like impeller received in a shallow circular depression in a side wall of the container. The drive to the impeller is through a belt, access to which is gained through a removable panel in the skirt. Specifications 648,702 and 701,977 are referred to.

Title: Improvements in or Relating to a Sensor for a Braking System
IPC: G01P15/00
Filed: 1978-10-31
Abstract: A sensor for responding to the rate of deceleration of a rotating vehicle wheel includes a flyweight 110 coupleable for rotation in response to wheel rotation and decoupleable in response to a rate of deceleration of the wheel which exceeds a certain threshold rate. A brake device 126 is operatively connected with the flyweight 110 for constantly exerting on the flyweight a torque resisting rotation of the flyweight. Provision is made for signalling of any occurrence of an excessive rate of deceleration of the wheel continuously for the interval of time during which a threshold rate is exceeded, and the brake device 126 may be operable in response to such signalling for changing the level of torque exerted. Coupling of flyweight 110 to input shaft 111 is via planetary gear 134 (or a claw clutch) incorporating a switch 142 to signal overun of flyweight 110 due to shaft 11 deceleration above the threshold value, torque limiting coupling 121, freewheel 124, and brake device 126 which may be electrical, electro- magnetic, or mechanical. <IMAGE>

Title: A games racket
IPC: A63B49/02
Filed: 1978-11-24
Abstract: A games racket comprising a frame 2 and one or more interwoven strings 4 tensioned within the frame, characterised in that the frame includes an inwardly projecting rigid lip 3 to one side of the strings for contact by the strings when the latter are struck from the other side. When struck in this way, the effective length of the strings is reduced and their tension thereby increased as compared with being struck from said one side. Accordingly a user may compensate for differences in his power as between forehand and backhand shots. <IMAGE>

Title: Washing apparatus for vehicle
IPC: B60S3/06
Filed: 1979-06-06
Abstract: A washing apparatus for vehicles has a portal assembly 1 which is reciprocable over a vehicle 3. On the portal assembly 1 are mounted one or more brushes 8 mounted in carriages movable relative to the portal. Electric motors 4, 14 act through transmission means 5, 15 to drive the portal and the brush carriages respectively. Each combination of motor and transmission means can accommodate slippage. The motors for driving the portal and the brush carriage are controlled in response to the speed of movement of the brush carriages and the portal respectively. At the start of the washing cycle the brushes are stationary and the portal is moved until a brush engages the vehicle. The portal then stops moving and the brushes are driven across the engaged face of the vehicle. The slippage in the drive of the portal results in the brush being pressed against the vehicle throughout its movement. If the brush meets an obstruction 3a the portal is retracted (arrow B). <IMAGE>

Title: Connection of underwater lines
IPC: E21B43/013
Filed: 1979-12-04
Abstract: In connecting hubs 72 on underwater oil/gas pipe lines 13, control lines and electrical conduits (Fig. 3 not shown) to mating hubs 24 on an underwater manifold center or other production unit (see 79-41301 also), a connector tool 100 is used to draw and clamp the aligned hubs 24, 72 together. The tool 100 is lowered from the surface and comprises a seal plate 124 which is introduced between the spaced-apart hubs 24, 72. Forks 105, 106 on the tool 100 urge the hubs 24, 72 together and into engagement with the seal plate 124 (Fig. 18 not shown). Jaws 126, 128 which are then actuated by rotation of a socket 115 driven by a motor 113 and gearing 114, clamp the hubs 24, 72 together. The jaws 126, 128, sealing plate 124 and associated mounting plates 120, 122 are disengaged from the remainder of the tool 100 by applying hydraulic fluid to a sprung- loaded piston 13 in a pin 118 to urge a conical member 134 downwardly and allow retraction of latches 132 from plate 122 (Fig. 18, not shown). The tool 100 may be re-connected to the plate 122 to allow the hubs 24, 72 to be disconnected and the seal plate 124 replaced. <IMAGE>

Filed: 1979-12-04
Abstract: A cylinder (109) is first clamped in the apparatus (101) by clamp (111) with socket (108) in engagement with a damaged valve (110). The socket (108) is fixed to a shaft (106) which is provided with a first arm (114) which is mounted fast on the shaft (106). A hammer (115) is pivotably mounted on the shaft (106) via arms (116 and 117). When the apparatus (101) is rocked first arm (114) hits hammer (115) tending to turn damaged cylinder valve (110). Rocking is continued until the damaged cylinder valve (110) is loosened. Thereafter the damaged cylinder valve (110) can be removed by rolling the whole apparatus. Gas released from the cylinder is initially contained in the apparatus and is subsequently vented through line (112). The whole apparatus is then purged with nitrogen introduced through line (113) before the cylinder is removed by separating sections (102 and 103) and releasing clamp (111). <IMAGE>

Patent GB-2061673-A (GB)
Title: Transmitter-receiver synchronizer
IPC: H04L25/05
Filed: 1980-09-18
Abstract: A transmitter-receiver synchronizer is described for use in terminating T1 lines from a subscriber line switch at a central time division multiplexed switching system. A shared rate converter provides bidirectional data rate conversion between the 1.544 Mb/s T1 line and the 2.048 Mb/s switching system. This converter uses two buffer memories (1, 2) so controlled as to effect the above conversion. Thus during a first frame time interval a first data frame at the first rate is stored in the first buffer memory and a second data frame is stored at the second rate in the second buffer memory. During a second frame time interval, the frame in the first buffer memory is read at the second data rate, and the frame in the second buffer memory is read at the first data rate. Also during the second interval another frame at the second data rate is read into the first buffer memory and another frame at the first data rate is read into the second buffer memory. Thus the functions of the two buffer memories alternate on successive frame time intervals.

Title: Filling effect designs on a stitch-through fabric
IPC: D04B21/14
Filed: 1980-09-22
Abstract: A stitch-bonded fabric made on a stitch-through type machine involves the application of a textile pattern design element (e.g. a single yarn end) disposed along non-rectilinear pathways, with segments extending essentially perpendicular to the longitudinal direction of the fabric. A block pattern may be formed thereby. A single system of longitudinal knitting thread wales with loops on the rear surface of the fabric and laps on the front surface, binds and secures the design element into an integrated unitary textile structure. In addition the fabric may include a layer of non- woven fibrous batting and a layer of filling yarns. The textile element 107 is applied by a unitary mechanism 101 which moves transversely of the fabric wales and includes a feed tube 107 and rotary brushes 109a, 109b which place and hold down the element in the stitch-forming zone. <IMAGE>
