Patent GB-2158228-A (GB)
Title: Astigmatic non-contact optical probe
Inventor: DOTY JAMES L
IPC: G01B11/24
Filed: 1984-05-05
Abstract: An optical probe, having particular application in contour mapping and small distance gauging, includes a light generation and projection means 14, 17 which projects a light beam 16 through crossed cylindrical lenses 18, 20 to induce astigmatism in the beam. The astigmatic beam is then directed onto a target surface 30 to be mapped. The back-scattered radiation 32 reflected from the target surface is collected by a collection means 34 and focused onto a photodetector 36. The shape of the image projected onto the photodetector is dependent upon the distance between the probe and surface. By observing the output of the detector the distance between the probe end surface may be measured, or maintained constant, and a contour map generated using known mapping techniques. In an alternative embodiment, astigmatism is induced in the reflected beam, instead of in the incident beam. <IMAGE>
Patent GB-2140910-A (GB)
Title: Heating of enclosures
Inventor: BOOKER PAUL IAN
IPC: F23L15/02
Filed: 1984-05-21
Abstract: In the operation of an enclosure such as a glass tank, heat is supplied by firing one or more burners of a kind in which air is initially employed to atomise the fuel. Oxygen-rich gas, typically substantially pure oxygen, is subsequently substituted for the air. This substitution is carried out without decreasing the flame length. Typically, on making the substitution, the rates of supply of atomising agent, and secondary air are reduced. A burner head with a central passage 32 for oil, and outer passages 30 for atomising gas, projects atomized fuel from an orifice 48. The cross section of a passage 44, and the orifice size, may be reduced when oxygen-rich gas is used. <IMAGE>

Patent GB-2167230-A (GB)
Title: Semiconductor processing
Inventor: PLUMB RICHARD GORDON SAMUEL
IPC: H01L21/225
Filed: 1985-03-08
Abstract: Diffusion of a volatile dopant, for example zinc or cadmium, into a surface region of an InP based material (5), in particular GaInAsP, to which electrical contact (8) is to be made is carried out, for example, in a closed capsule with an overpressure of Zn, As and P, with the surface region in intimate contact with a surface of a GaAs wafer (9 - Fig. 2) which surface is doped with the volatile dopant. This has the effect that the InP based material sees a high concentration of the volatile dopant at all times as well as altering the surface alloy composition so that it is higher in GaAs following diffusion, resulting in a higher electrical doping density. <IMAGE>

Title: Hopper fed abrasive blast cleaning machine
Inventor: HAYES FRANCIS JOSEPH
IPC: B24C7/00
Filed: 1985-05-13
Abstract: An abrasive blast cleaning machine comprises a pressure vessel (12) for containing abrasive media under pressure and having first inlet (13) for enabling pressurisation of the pressure vessel, an outlet (15) including a valve (30) for controlling the flow rate of abrasive media under pressure out of the pressure vessel, and a second inlet (17) for enabling charging of the pressure vessel with abrasive media from a storage vessel (10) which may be located on top of the pressure vessel. The second inlet (17) is controlled by a valve (14) operated by a pneumatic double-acting cylinder (20) or by means of the pressure utilised to pressurise the vessel (12). When the pressure vessel is pressurised the valve (24) closes the second inlet (17) maintaining the pressure in the pressure vessel (12) but when the pressure is switched off the valve (24) opens inlet (17) allowing abrasive media to flow from said storage vessel (10) into said pressure vessel. Even for a large capacity abrasive blast cleaning machine only a small pressure vessel is required which reduces the cost of manufacturing as well as reducing the overall weight of the machine and improving its handling abilities. <IMAGE>

Title: A transport cart for one or two persons and or goods
Inventor: O'NEILL PETER DAMIEN
IPC: B62K5/00
Filed: 1986-08-26
Abstract: The cart is a twin skid or four or three-wheeled device, with fixed or steerable wheels to move by pushing off with the feet and riding the runners. It offers mobility and maximum security through the extended positioning of runners/wheels (ice blades/runners for ice and snow) and brakes for stopping. It can be propelled by non-human energy. Steering and part support is through cross bar handle, plus bodyweight acting on the flexibility of the frame or moveable steering crossbar. While the upright user can walk between the runners the primary purpose is to be carried along on them being a means of transport as well as support. A key element is a front seat to carry another person (often a child or elderly person) or for the placing of goods of any kind when required. A kneeling extension makes it usable by one unable to position a leg vertically on the foot rests. <IMAGE>
