Title: Detachable tread for attachment to a tyre and wheel assembly of e.g. a golf buggy or trolley
Inventor: CAMERON EDWIN LINDSAY
IPC: B60C11/02
Filed: 1984-06-21
Abstract: The detachable tread (20) engages the radially outer surface (21) of either a solid or pneumatic tyre (13) of the buggy wheel (11, 12) and has a ground engaging portion (22) that is substantially axially wider than the tyre (13). The tread is preferably injection moulded in elastic plastics and can be stretched onto the solid tyre of the buggy wheel. The flanges 25, 26 of the tread (20) may be fastened to the tyre (13) e.g. by threaded fasteners. For a pneumatic tyre, the detachable tread (20) may be inextensible e.g. by reinforcements and is mounted by deflating the tyre, positioning the tread and reinflating the tyre. As the width of the portion (22) of the tread (20) substantially greater than that of the tyre the tread increases the area of contact of the wheel with the ground and thus decreases the pressure on the ground as is most desirable with gold trollies. The invention can also be applied to prams, supermarket trollies and wheel-barrows. <IMAGE>

Patent GB-2173055-A (GB)
Title: Circuit arrangement for starting discharge lamps
Inventor: HASLAM DAVID FRANK
IPC: H05B41/04
Filed: 1985-03-29
Abstract: During an initial part of a starting cycle, a semiconductor switching device 24 presents a low impedance path between electrodes 15, 16 which therefore heat up until a capacitor 37 has charged sufficiently to turn on SCR 32 causing device 24 to turn off and a high voltage ignition pulse to be generated with the aid of inductive ballast 12. Means are provided to effectively isolate the capacitor 37 from the A.C. supply voltage during running of the lamp 14 so that the capacitor 37 is prevented from being maintained charged and thus SCR 32 is prevented from being held conductive. The isolating means allows capacitor 37 to discharge via path 38, 39, 26, 27 when the lamp is running so that the lamp can be restarted if the A.C. supply is interrupted even for a relatively short period. The isolating means may be a bidirectional breakover device 40 located at the input to a rectifier bridge 18, 19, 20, 21 and having a breakover voltage greater than the operating voltage of the lamp 14. Alternatively, a unidirectional breakover device may be located at the output of the rectifier bridge, or bridge diodes 18, 19 may be breakover diodes, or a resistor 29 may be a voltage dependent resistor which presents a very high resistance when the lamp is running. <IMAGE>

Patent GB-2179404-A (GB)
Title: Peristaltic device
Inventor: ROBERTSON THOMAS JOHN MCNEEL
IPC: F04B43/08
Filed: 1986-08-15
Abstract: A peristaltic duct, e.g. in a peristaltic pump motor or valve, is such that in its relaxed or unstressed state the flow passage therethrough is occluded. In use, an opening force is applied so as to open said flow passage and allow flow of fluid therethrough, e.g. gas, liquid, or liquid containing suspended solid(s). The opening force may be applied to the duct by a number of spaced actuators (31, Fig. 4, not shown) sequentially operated by crank means or, alternatively, may be applied by spaced electromagnets and an associated series of permanent magnets (48, Fig. 5) or an associated permanent magnet flexible strip (64, Fig. 6). In another arrangement the duct passes through a torroidal chamber 71, Fig. 7, which is evacuated to cause the duct to open its flow passage. However, the chamber contains some liquid having a suspension of magnetically responsive particles so that when subjected to a magnetic field by energisation of an electromagnet 74 to 77, the liquid suspension between the associated pole pieces of the electromagnet will exert a pressure sufficient to close the adjacent region of the duct. <IMAGE>

Title: Spooled umbilical system
Inventor: SIVITER DAVID JOHN
IPC: B65H75/34
Filed: 1988-09-19
Abstract: An umbilical 30, Fig. 1A, e.g. for a submarine, is anchored at 34 to a winding drum, and continues through the drum spindle to the inside of auxiliary drum 24 to be wound thereon. The umbilical's end passes from drum 24 through basket 26 to fixed coupling 38. When the umbilical is unwound from the drum, it also unwinds from drum 24 to lie in folds in basket 26. The use of slip rings and rotary couplings is thus avoided. Alternatively (Fig. 2), the unwound umbilical runs radially inwardly between driven haul-off belts to run axially from the drums. This alternative may be used in a submarine launching cradle (100, Figs. 6 & 9), where four end doors (106) are pivoted open to release the submarine horizontally. The line about drum 24, and possibly umbilical 30 itself, comprises (Fig. 10) a flat, flexible ribbon where sheath (302) has bores forming or containing combinations of electric cable, optical fibre and hose. The sheath may contain hawsers, and glass fibre-resin stiffening rods. The umbilical ribbon may have vanes to turn it edge-on to water flow. In a further embodiment Fig. 11, the umbilical 404 extends to and through spindle 408, the umbilical being wound/ unwound about the drum and its spindle. The submarine may have a remotely operated vehicle (214, Fig. 9) where umbilical is simply drawn from folds in a box (Fig. 12). <IMAGE>
