Patent GB-2154373-A (GB)
Title: Improvements in chip resistors
Inventor: REYNOLDS QUENTIN MICHAEL
IPC: H01C7/00
Filed: 1985-02-11
Abstract: A method of forming chip resistors in which a resistive coating is applied to an insulating substrate which is subsequently divided up into single chip components includes the step of providing end terminations for the individual chip resistors before the sheet is divided up. This is achieved by forming a hole 13 in the substrate 11 at the position of each end termination and then coating the holes with an electrically conductive material 14 which electrically connects with the adjacent region of the resistive coating 12. In order to improve the solderability and the reliability of the end terminations the holes 13 may be filled with solder 15. The electrical value of the resistive element coating may then be adjusted to a precise value by trimming away some of the resistive element material with a laser. Finally, the substrate is divided up into the single chip resistor components.

Title: Method of producing a flocked, flat-shaped textile structure, and a flexible, flat-shaped flock structure produced thereby
Inventor: LENARDS GERHARD
IPC: D04H11/00
Filed: 1985-04-12
Abstract: The invention relates to a method of producing a flexible, flat-shaped flock structure formed from a substrate, adhesive layer and flock, said method comprising calendering the flat-shaped structure after the flocking process. This method permits a fine surface to be achieved with a uniform nap. The calendered, flat-shaped flock structure may be additionally embossed. This enables any desirable surface texture to be obtained. Depending on the choice of substrate, adhesive and flock, improved properties in respect of appearance, resistance to wear by friction, bi-elasticity, air-permeability, insulating effect and feel, can be obtained.

Patent GB-2197406-A (GB)
Title: Pipe fitting tool
Inventor: POWELL DEREK
IPC: F16L55/00
Filed: 1986-10-30
Abstract: A tool body has two sections 1,2 hinged together at 3,4 to allow them to be assembled together around a length of piping 5 to define a fluid-tight chamber surrounding the piping. A cutting means 16 mounted upon body section 1 cuts through the piping 5 and forms a seal over one of the resulting cut piping ends. Section 2 has a part 2b which may be removed to expose the piping in the chamber while part 2a remains in place over the sealed cut piping end, thus allowing a new pipe fitting (not shown) to be secured to the left- hand cut end of pipe 5. Part 2b is then closed and cutting and sealing means 16 withdrawn to allow the right-hand cut end of pipe 5 to be secured to the new fitting within the fluid-tight chamber, after which the entire tool can be removed. Thus the new fitting can be installed in the system of which pipe 5 forms a part without the need for draining the system. <IMAGE>

Patent GB-2196051-A (GB)
Title: Fastening mechanism
Inventor: HOPPER HANS PAUL
IPC: F16L37/00
Filed: 1987-10-08
Abstract: The mechanism is suitable for releasably fastening two opposing faces by movement of the faces towards each other and has a stem 10 and a sleeve 15 surrounding it. The stem 10 and sleeve 15 are mounted on separate plates 10A, 11 capable of relative axial movement. The stem and sleeve each have projections and adjacent profiles as shown and the outside of the sleeve 15 has a shoulder 31; the mechanism also has a receptacle 32 into which the stem and sleeve are to be fastened. With the projections 23, 24 and 27, 28 on the stem and sleeve 15 abutting, the sleeve 15 cannot enter the receptacle 32. However, since the stem and sleeve can move axially relative to each other, the stem and sleeve can be fastened into the receptacle by pushing the stem relative to the lock sleeve to reduce the diameter of the sleeve and can be released by pulling the stem relative to the sleeve. Figs. 2A-2D illustrate the fastening sequence as drive plate 10A is moved e.g. manually by a diver. The mechanism may join parts to transmit hydraulic or electrical power and be used in subsea oil production. In Fig. 3 a spring 40 regulates movement between plate 10A and plate 11 -the separate stem spring 12 and sleeve spring 18 of Figs. 1-2D have been replaced by a single spring 39. <IMAGE>

Filed: 1989-04-26
Abstract: A marble-faced laminate includes a substantially rigid panel 3 having a core 4 of foamed polyisocyanurate (or polyisocyanurate-modified polyurethane) sandwiched between two reinforced skins 5 and 6. The facing is a thin marble sheet 1 which has a resin-bonded glass-fibre backing 2 that is bonded by an epoxy-resin layer 710 skin 5 of the panel 3, and an aluminium foil 9 is bonded to the other skin 6 via an epoxy-resin layer 8. The backing 2 is applied (as 11 or 12, Fig 2) to the marble before the sheet is cut from a larger block (10 Fig 2), and the skins 5 and 6 are formed during manufacture of the panel 3 by allowing the uncured plastics of the core 4 to soak into glass fibre, so that with foaming and curing of the core 4, dense skins of the resin reinforced with partially-exposed glass fibres are formed. Stone other than marble (eg granite) may be used for the facing, and instead of sheets the marble or other stone may be provided in blocks or other divided (eg chippings) form on the glass-fibre backing layer 2. Plaster of Paris, clays and earths may also be used as facings. <IMAGE>
