Title: Spacing Spiral for Coaxial Tube Systems
IPC: H01B12/02
Filed: 1979-06-08
Abstract: A spacing spiral for a coaxial tube system in which, in use, there is a temperature gradient between radially successive tubes of the coaxial system e.g. a coaxial tube system, constituted by an electric cable operated in a super-conductive state, or a pipeline for conveying a heated or cooled fluid medium, comprises individual cords (1, 2, 3 & 4) assembled in the form of a plait. Preferably the cords are of circular cross-section. The cords may for example be of metal and/or synthetic material. Furthermore, individual cords may be of composite construction, e.g. comprising synthetic and metal threads twisted together. A particularly useful specific construction employs four individual cords which follow an undulating course along the length of the spiral, two of the four cords (1 & 2) being disposed generally in one plane and the two other cords (3 & 4) being disposed generally in a plane at right angles to the first one. The plaited spiral enables heat transfer (in the radial direction of the coaxial tube system) to be kept down to a particularly low value without loss of flexibility. <IMAGE>

Title: A Toy, Electrically Driven, Racing Car
IPC: A63H18/12
Filed: 1980-01-25
Abstract: A toy racing car is steered by driving either one or the other of its rear wheels 11. An electric motor transmits drive to a pinion 17 which can rotate in either direction. When the pinion 17 rotates, the crown wheels 4 rotate in opposite directions, and a pawl 9 with a driving surface comes into driving engagement with a corresponding surface of a cam 14. This driving connection will be produced at the side of the vehicle where the pawl 9 is rotating in a clockwise direction. On the other side of the vehicle the pawl 9 will be rotating anticlockwise and will not engage the cam surface 14, and so that undriven wheel will be able to freewheel. The cam surfaces 14 are formed on the wheels themselves, so that they can present the largest possible area, and facilitate assembly. <IMAGE>

Title: Dialysing and ultra-filtering device
IPC: A61M1/22
Filed: 1980-08-04
Abstract: A dialysing and ultra-filtering device comprises hollow, i.e. capillary, fibres 3 of Cellophane (Registered Trade Mark) or the like, mounted for passage of hematic liquid within a chamber through which dialysing solution passes, wherein the chamber is defined by a container 1 having the shape of a parallelepipedic substantially crushed box; the fibres are disposed between two opposite ends (heads) 22, 24 of the box and on the two smaller sides at right angles to the heads provision is made for orifices 18, 20 for the inflow and outflow, respectively, of the dialysing solution, which thus passes through the container along paths perpendicular to the capillaries.

Title: An air-pressure regulating apparatus
IPC: B66F19/00
Filed: 1980-09-19
Abstract: An air-pressure regulating apparatus suitable for regulating the pressure of air supplied to a piston- type of air-balancer has a hollow body 1 divided into two chambers 1a and 1b by a diaphragm 2, chamber 1a being vented to atmosphere and chamber 1b having an outlet port 4, an inlet valve 5 communicating with an inlet port 3, and a pressure relieving valve 7. A first compression spring 12 mounted between discs 10a and 10b serves to urge the diaphragm 2 towards the chamber 1b, the spring force being adjustable by means of screw-threaded adjuster 11. A cylindrical cam 15 can be operated manually to hold the disc 10a at a position where the inlet valve 5 remains open and the pressure relieving valve remains closed, or at another position where the inlet valve 5 remains closed and the pressure relieving valve remains open. In the illustrated position of the cam 15, the disc 10a is free to move over a limited range, thereby allowing pressure regulation to take place. A second adjustable spring 20 also biasses the diaphragm, irrespective of the action of the cam 15 on the disc 10a. <IMAGE>

Patent GB-2090389-A (GB)
Title: Drying printed metal objects
IPC: F26B23/02
Filed: 1980-11-15
Abstract: An oven (10) for rapidly drying materials printed on small metal objects, such as flat metal sheets (50) for use in making metal cans, comprises a flame-heating section (30) into which such sheets are carried on a conveyor (48), and a 'hot air' heating section (32) into which said sheets are subsequently conveyed. Flames produced by gas- fired burners (73) in the flame heating section impinge directly on said sheets, and hot combustion gases are led off via a communicating duct (40) into the hot air heating section, where they emerge on to said sheets from nozzles (84). The flow of gases through said communicating duct is variable, by means of a fan (44), and their temperature can be increased, by operation of a gas-fired control burner (42). A controllable exhaust duct (34) controls the proportion of combustible solvent in the flame heating oven section. Recirculation of some hot gases from the hot air oven section is achieved via a recirculation aperture (87) in the roof of that oven section. <IMAGE>

Patent GB-2093359-A (GB)
Title: Carbonated drinks machine
IPC: A23L2/54
Filed: 1981-02-24
Abstract: An appliance for making carbonated beverage of the type in which carbon dioxide is introduced into a bottle (27) of water under pressure, a safety valve (33) being provided to release the pressure when it reaches a predetermined value. A separate vent valve (38) is provided to release the pressure above the water in the bottle so that the bottle can readily be removed at the termination of carbonation, the vent valve being positioned very close to this space above the water so that a minimum of carbon dioxide is wasted. The vent valve also vents the space (26) above the stopper to release pressure which forces the stopper into close engagement with the mouth of the bottle. <IMAGE>

Title: Magnetic clasps
IPC: E05C19/16
Filed: 1981-05-22
Abstract: A magnet clasp has a stationary part A and a movable part B.

Title: Trailer vehicle
Inventor: JONES FRED ALAN
IPC: B60P3/06
Filed: 1981-10-15
Abstract: A trailer vehicle has a platform 9 supported adjacent to the rear end 4 thereof by one or more pairs of road wheels (2 & 3) and a coupling at the front end 7 thereof whereby the vehicle may be coupled to a tractor vehicle. At least one supporting leg (8) is pivotally mounted beneath the platform, the or each leg carrying a wheel (10) at the lower end thereof. Drive means such as a hydraulic or pneumatic ram (11) is mounted between the platform and the leg or legs to pivot the legs relative to the platform whereby the platform may be tilted about the road wheels or one pair of the road wheels to lower the front end 7 of the platform on to the ground. Loading, for example of a tracked vehicle which cannot readily be driven on public roads, is thereby facilitated. The ram or rams can then be extended again to raise the platform for reconnection of the trailer vehicle to the tractor vehicle. <IMAGE>

Title: Pole ladder
Inventor: SMITH GEORGE
IPC: E06C1/383
Filed: 1981-11-30
Abstract: The invention comprises a climbing ladder capable of being collapsed into a single pole unit.

The method of the collapse is to bring the two side posts together by rotation of pin joints at the ends of the rungs. The two side posts are recessed to receive the rungs and conceal them from view once the ladder has been collapsed. In the collapsed position there exists only one single pole unit. The ladder is held in the open position by a suitable diagonal member fixed to both side posts. The ladder is held in the closed position by a suitable openable clip.

Title: An hydraulic damper
Inventor: NICHOLLS LAWRENCE GEORGE
IPC: F16F9/516
Filed: 1982-01-22
Abstract: An hydraulic damper for controlling movement between relatively movable parts of a hospital bed or the like comprises a piston 4, carried by a piston-rod 6, working in a sealed, liquid-filled chamber 13 within a cylinder 1. The piston 4 includes at least one axially extending passage 16 permitting an unrestricted flow of liquid through the piston 4. During movement of the piston 4 in the cylinder 1 in one direction a relatively movable valve plate 17 engages with the piston 4, and a restricted orifice in the plate 17 permits a restricted flow through the passage 16. During movement in the opposite direction the plate 17 is spaced from the piston 4, permitting a free flow. The chamber 13 is expansible to compensate for expansion and/or displacement of the liquid, one end of the chamber 13 comprising an axially movable annular seal 10 through which the rod 6 passes. A spring 14 urges the seal 10 towards the other end of the chamber 13 to pressurise the liquid. <IMAGE>
