Abstract: 978,245. Clasp knives; marline-spikes; screwdrivers; wrenches. W. G. IBBERSON, [trading as GEORGE IBBERSON & CO.]. Oct. 28, 1963 [Nov. 2, 1962], No. 41576/62. Headings B4B, B4C and B4W. A clasp knife comprises a blade 10 having a hollow ground cutting edge and a slotted shackle pin screwing and unscrewing member 12 both pivoted to the knife at 16 and a marline spike 14 pivoted to the knife at 24. The back edge of the blade is of substantially uniform thickness for a width less than half the width of the blade, the remaining width of the blade being the hollow ground part thereof. The marline-spike is pivoted between the outer scales 18, 22 of the knife. The blade is pivoted to the scale 18 and to an intermediate scale 20 and the slotted member 12 is pivoted to the scales 20, 22. One end of the scale 20 is extended for use as the blade of a screwdriver. A shackle 28 for attaching a lanyard is pivoted to the knife at opposite ends of a pivot pin 30, the pivot pin having an intermediate portion 32 of rectangular cross-section which is capable of abutting against back springs 26 which bear against the tang of the marlinespike whereby pivotal movement of the shackle will effect locking and unlocking of the marlinespike in either its closed or open position. Reference has been directed by the Comptroller to Specification 892,670.

IPC: H02K44/10
Filed: 1964-10-16
Abstract: 1,082,147. Generators operating by electromagnetic interaction with fluids. COMPAGNIE GENERALE D'ELECTRICITE. Oct. 16, 1964 [Oct. 24, 1963], No. 42427/64. Heading H2A. A magnetohydrodynamic generator has the segmented electrodes along each wall of the duct connected together so that the potential difference between them is sufficient to cause arcing in the direction of working fluid flow to ionize the boundary layer of plasma adjacent the electrodes. An alternating voltage may be applied between two electrodes by transformers supplied from a single or three-phase source. The transformers may be connected between two adjacent or spaced electrodes (Figs. 1 and 2) and in the latter case the pairs may overlap to eliminate eddy current losses. In a modification resistors are connected either between two adjacent or spaced electrodes (Figs. 3 and 4) so that the Hall voltage generated will create the necessary potential difference.

Filed: 1973-09-12
Abstract: 1449005 Travelling wave shedding looms MAQUINARIA TEXTIL DEL NORTE DE ESPANA SA 12 Sept 1973 [12 Sept 1972] 42928/73 Heading D1E A vertical travelling wave shedding loom passes the shuttles around a closed loop path embracing two shedding motions, two beat-up and shuttle picking motions and, at each side of the loom, a weft winding mechanism, so that two fabrics are woven side-by-side. Shedding: Groups of healds 16 are spaced apart by plates 5, 6 and held at different levels by rods 10. A chain 42, travelling around the closed path, has opposed cam units 55 with shafts 32 and pulleys 30, 31 with belts 29, 36, the pulleys 30, 31 being rotated as the chain traverses by a rack and pinion 40, 33. The belts 29, 36 of one cam unit 55 are at a different heald level to the corresponding cam unit 55 at the other end of the healds 16 so that, as the chain traverses, each pair of cam units sheds the healds in front of a shuttle. Picking: Under the healds 16 are picking reed blades 19, alternately arranged in mirror image so that nebs in the blades 19 act on rollers 47 on the shuttles 54 to traverse them when the blades 19 are transversely reciprocated by rollers 43, 44 on the cam units 55. The nebs 27 form a guiding groove for rollers 46 on the shuttle 54 whose weft spool 45 beats-up the previously laid weft as it is traversed and lays the new weft. Weft winding: As the shuttles 54 leave a shed they are engaged by a fork 64 on a spring loaded telescopic arm 62 which presses the shuttle against a track so that rotation of the arms carries round the shuttles to the entry of the other shed. The shuttle spool 45 is simultaneously engaged by a bellows 74 and weft 63, extending from a guide tube 71 to be held by suction in the arm 62, is hooked into a catch on the side of the spool 45. As the arms 62 rotate a pinion 69 on the arm engages a rack 70 so that the bellows 74 rotate and the weft is wound onto the spool 45. Shears sever the weft as the shuttles leave the winding mechanisms.

Six rotary switches, two 45a, 45b being shown are mounted on shaft 47 and through circuitry are connected to three rows of six lamps indicating which kegs are full, in use or empty. The circuitry includes a bar start switch and a bar switch where by the shaft 47 is rotated to select a required keg. Shaft 47 has a manual knob 73 whereby pressure may be applied to any keg to condition the contents. Conditioning pressure may also be applied manually by a lever catch released by the valve operating cam or manually by a bar switch operating a rotary switch, the valve arrangement having additional camoperative valves such that a keg is not available at the bar during conditioning. Gas bottles 83, 85 may also change over automatically via circuitry Rb acting on valves 83b, 85b. There may be a probe or float switch in each keg and the kegs may have pressurised plastic liners.
