Title: A vehicle entry system for invalids and a wheel chair suitable for use with the entry system
IPC: B60N2/02
Filed: 1981-03-16
Abstract: A vehicle entry system for invalids, comprises a platform (51) which may include a beam (52) and a carriage (53) slidable on the beam by power operated means (61, 62), and means for swivellably and non-tiltably mounting the platform in a motor vehicle for movement between a loading or unloading position in which the platform projects outwardly through an adjacent door opening (50) in the vehicle and a position in which the platform is housed entirely with the vehicle. The platform also has means for releasably retaining the platform in the latter position. A wheel chair is capable of straddling the platform with its ground engageable wheels (77, 78) on opposite sides of the platform. The wheel chair also has means, e.g. electrically or hvdraulically operated means (76) for raising the wheels relative to the seat (72) of the wheelchair so that when the seat is mounted on the platform of the entry system, the wheels can be raised to clear the sill of the door opening when the platform is swung into the motor vehicle. <IMAGE>

Title: PTC Conductive Polymers and Devices Comprising Them
IPC: B29C48/12
Filed: 1981-05-18
Abstract: PTC compositions comprise a conductive filler, e.g. carbon black, dispersed in a mixture of two crystalline polymers of different melting points, the higher melting of the two polymers having a melting point which is at least 160 DEG C and at least 25 DEG C higher than the melting point of the other polymer, and the compositions not increasing in resistivity by a factor more than 2 when maintained at 150 DEG C for 1000 hours. They are suitable for self- limiting heaters which can be used on apparatus which is periodically subjected to high temperature, e.g. during steam-cleaning thereof, preferred devices being rendered more flex-resistant by the presence of a layer of a relatively flexible composition which is melt-fused to a PTC element composed of the novel composition. The compositions are preferably annealed at a temperature between the melting points of the two polymers.

Title: Machining or measuring tapering surfaces
IPC: G01B5/20
Filed: 1981-05-20
Abstract: A workpiece 3 is formed with an internal or external surface 3a which tapers frusto-conically from one end of the workpiece to the other and has an arcuate axis of symmetry 5, by moving the workpiece along an arcuate path 4b relative to a rotary cutting tool 7a having an axis of rotation 8 which is tangential to the arcuate axis 4b at a point 5a constituted by the centre of rotation of the cutting edge of the tool. The tool is radially expanded or controlled by relative movement of a tapered shaft 10 or a tapered bore tool support. A planing tool may used to form a polygonal cross-section surface, again with a radial variation and having a curved axis. The already machined surface may be measured for divergences by a clock gauge constructing analogous to this tool. <IMAGE>
Patent GB-2100508-A (GB)
Title: Method of making semiconductor devices
IPC: H01L21/304
Filed: 1981-06-17
Abstract: A method of manufacturing semiconductor devices avoids the need to etch windows in a passivation layer which overlays a semiconductor surface to enable electrically conductive contacts to be made to the semiconductor material. The method uses a grinding machine 14 to remove the passivation material 9 from those regions of the semiconductor material 1 at which electrically conductive contacts are to be formed. A large number of semiconductor devices can be fabricated simultaneously from a slice of silicon and the individual devices are defined by a pattern of recesses 7 formed in one surface of the slice. The grinding operation which removes the passivation material from the surface of the individual devices leaves the passivation material in the recesses where it is needed to protect what would otherwise be exposed p-n junctions. <IMAGE>

Title: Spinning machine
Inventor: ALLEN WILLIAM DOUGLAS
IPC: D01H3/00
Filed: 1983-07-21
Abstract: A spinning machine comprises a base (1), a support (2) mounted on the base and a shaft (4) rotatably mounted on the support (2). The shaft is inclined to the base (1) and has an upper pointed end (5) to serve as a spindle. A wheel (11) is mounted on the shaft (4) adjacent to the lower end thereof and a foot pedal (14) is pivotally mounted on the base (1). The foot pedal is arranged to drive the shaft (4) by drive means comprising a cord (15) which is fastened at one end to the foot pedal (14), wound around the lower end of the shaft (4) and fastened at its other end to a spring (16) which is detachably attached to the base (1) by a hook (17). An end cap (13) prevents the cord (15) from slipping off the lower end of the shaft (4). Depression of the foot pedal (14) causes the cord (15) to tighten around the shaft (4) to rotate the same. If pressure on the pedal is then relieved, the spring (16) will return the pedal to its former raised position, the cord (15) slipping around the shaft (4) as the latter continues to rotate. The wheel (4) is desirably provided with weights to increase its inertia and to enhance the fly-wheel effect imparted to the shaft. A bobbin (8) is detachably fitted on the shaft (4) and yarn (9) can be spun on the bobbin when the shaft (4) is rotated in one direction. If the cord (15) is wound around the shaft (4) in the opposite direction, the shaft can be rotated in the opposite direction so that spun yarns can be plied onto a bobbin (8) fitted on the shaft. <IMAGE>

Title: Form-fill-seal wrapping apparatus
Inventor: WILSON PETER GORDON
IPC: B65B9/067
Filed: 1984-04-10
Abstract: Microprocessor 60 controlled form-fill-seal apparatus has an article infeed conveyor 13, web advance and longitudinal sealing unit 19 and transverse sealing jaws 20 and 21 each of which is driven by its own separate motor M1, M2 and M3 respectively.
