Title: Electrical cable sheath cutting tool - has knife edges projecting into a cylinder to slit sheathing material
IPC: H02G1/12
Filed: 1973-05-15
Abstract: The slitting of the sheath to bare the cores of a telecommunication type cable can be carried out by using a hooked but pointed knife. This procedure can be dangerous and require a flat support surface. This cylindrical tool slides over the cable and can be sleeved to fit varying cable sizes. Levers, which are 'L' shaped are hinged at the lower end onto the cylinder, have a knife edge at the other end. These project into the cylinder through slots. The tool is drawn along the cable with pressure on the levers thus slitting the sheath. The penetration depth is controlled by an adjustable collar.

Title: Vitreous carbon structures - by carbonizing polyurethane strands soaked in furan resin
IPC: C04B35/524
Filed: 1975-03-11
Abstract: Carbon structures are made by (1) soaking at least one thin cross-sectioned strand of a flexible polyurethane resin with a liq. furan resin (precursor) to cause swelling of the strand by infusion of the resin through the strand; (2) removing substantially all the non-infused resin from the surface of the strand; (3) polymerising the resin (precursor) with a catalyst to form a thermoset resin to give a prod. weighing up to ca 6 times the wt. of the strand alone and (4) carbonising the strand under neutral or reducing gas or vacuum conditions in an oven which rapidly heats the strand to carbonisation temp. which allows crack-free carbonisation to occur in less than about 5 h. Prods. are carbonised strands in the vitreous or glassy carbon state, which are free from cracks due to the complete removal of the resin from the surface of the strands before carbonisation. Prods are useful for high temp. applications in neutral or reducing gas atmospheres or in vacuum.

Title: High fidelity loudspeaker enclosure - has two similar loudspeakers which are fitted in two separate compartments of equal volume and with adjustable coupling
IPC: H04R1/28
Filed: 1975-03-12
Abstract: An enclosure for a loudspeaker is designed to provide a flat frequency response from 50Hz upwards using two similar loudspeakers (3, 4). The basis fo the design relies on adjustable coupling between approximately equal compartments (1, 2) within the overall enclosure. The adjustment is made by varying the size of a circular hole (6) in the wall dividing the enclosure. Both loudspeakers are fed from the same source and are similar or identical. The actual placing of the speakers can vary as can the position and number of the coupling holes. A typical unit may have 21cm diameter speakers in a cylindrical enclosure 30cm in diameter and 60cm high.

Title: Seals for spindles of high pressure valves - combines chevron seals with O-rings for pressures above 1250 bars
IPC: F16J15/32
Filed: 1975-03-17
Abstract: The seal between the valve spindle (5) and valve body (1) is retained by the flange (9). The seal consists of a variety of chevron type rings (3, 4, 6) of suitable material to withstand the operating temperature. The outer sealing member consists of the sleeve (7) provided with two inner grooves and one outer groove for O-ring seals. This arrangement gives the advantages of the better sealing properties of O-rings but since there is a reduction in pressure along the spindle due to the effectiveness of the chevron seals the danger of the O-rings failing by extrusion is eliminated. For certain applications additional chevron rings may be fitted outside the O-rings.
