Title: Air conditioner for lorry cab - with unit mounted in rear window opening and air scoop on roof
IPC: F24F1/04
Filed: 1974-09-27
Abstract: An air conditioning unit for a lorry cab is designed to be fitted to an existing vehicle without extensive modification of the vehicle being required. It is attached to a panel which is inserted in place of one of the rear windows of the driving cab, and uses the window seal (11) for fitting round its edge. A sloping plat (13) projects above the cab roof (1a) to act as an air scoop and directs it towards a condenser (16) to pass through the unit, so that a set of baffles guide cold air forwards towards a fan near the top to pass through distributors in the cab, and exhaust air passes out through a grid (15) at the botom at the rear.

Title: Latch system for two doors of a cubicle - has bar across cubicle interconnecting two opposite door latches
IPC: E05C1/12
Filed: 1974-12-09
Abstract: A dressing cubicle with two separate doors, one each side, has both door latches interconnected by a rod (10), between both doors, located e.g. under a seat across the cubicle.

Title: Rotary arm press for mfg. ceramic mouldings - located alongside extruder for mass prodn. of verge tiles
IPC: B28B3/20
Filed: 1975-01-17
Abstract: Press for mfg. ceramic mouldings consists of a rotary arm on a vertical axis carrying the upper half of a die, the arm travelling from a feeding and pressing station to a flash-removal station and then to an ejection station. A conveyor carries the clay blank to the feeding and pressing station where the lower half of the die is mounted on a punch which moves upwards. In the flas-removal station, a set of cutters move upwards to remove the flash. A the ejection station, the moulding is transferred to a second conveyor. Because a rotary arm is used (i.e. instead of a complete table), the accessibility of the press is very high. Used to mfr. building components, e.g. verge tiles starting from an extruded blank. Simpler press construction and cost; the high accessibility obtd. by use of a rotary arm, reduces the times required for die-changing, setting-up and repairs.

Title: Inter- or after-cooler formed by 3 coaxial tubes - for cooling gases liable to decompose on compression
IPC: F28D7/16
Filed: 1975-08-21
Abstract: A gas produced by a chemical process is cooled in one or several stages during compression by tubular coolers, the gas being passed through an annulus in the cooler packed with metal tubes to dissipate the heat in the gas through the inner and outer surface of the annulus. A cooling agent is split into streams each of which can be separately controlled and run either parallel to or counter-current to the gas flow, along the inside and outside surfacs of the annulus of the cooler. The cooler comprises 3 coaxial tubes, each of different dia. and length, the inner two of which are suitable for withstanding high press. and have flanges screwed on at both ends. In the annulus between the two inner tubes lots of filling tubes are inserted, running parallel to the axis, these filling tubes being welded to each other at one end and at points along the length. A seal is maintained at each end of the annulus by header blocks which comprise a stuffing box with packing to seal with the inner tube, an inlet ar right angles to the annulus packed with short filling tubes, and and stud holes to allow clamping to the flange on the end of the median tube. A compression joint provides the seal between the flange and header block. The third outer tube surrounds the median tube and has nozzles for inlet and outlet of cooling fluid. Used for cooling gases, e.g. acetylene, ethylene oxide, propylene, that tend to decompose even with the absence of oxygen when compressed. Coolers are cheaper and less cumbersome than previous designs and give bette overall heat transfer.

Inventor: REDL GERHARD
IPC: H02M3/337
Filed: 1976-07-29
Abstract: D. C. converter providing a high stability supply esp. for emergency services normally relying on public supplies. The converter has a high efficiency and has a reduced change of state time for the switching transistors. The convertor is based on a control circuit using a high turns ratio transformer (StTr) fed from the junction of two series connected current switching transistors (T3, T4). The transformer secondary controls the base of the power transistor, each such transistor having a separate transformer, the individual transistors feeding an orthodox split winding transformer (W1, W1') and smoothing circuit. The two current transistors are driven by a square wave input to the base of one, the potential of the second base being set by a resistor to the supply.

Title: Clear water collecting device for purificn. tank - with triangular enclosure having vertical intake and right-angled exit at top
IPC: C02F1/00
Filed: 1977-02-28
Abstract: Fresh water selecting device, for integration into the circuit of a purification tank, consists of a triangular enclosure with a vertical opening at its base and an evacuation branch pipe at its summit; it replaces the sepg. partitions used hitherto, with all their fixing arrangements. The device is fitted in the purification tank, and is made from a moulded synthetic material. It has a vent at its summit and a perpendicular outlet connected to the tank outlet; its base has a vertical inlet. In use, the water to be purified entes by the pipe; the solids fall to the bottom, where they ferment. The floating bodies, entrained by the fermentation bubbles rise to the surface. A zone of clear water is established between the bottom of the tank, and the zone which is traversed by the bubbles and the floaters. As thr orififice is parallel to the entrainment direction of the floating bodies, it is impossible for any sludge to penetrate and only clear water gains access. The base of the device is inclined to the general direction of flow; it acts as an obstacle to the rising floating matter, prevents it from accumulating in the enclosure and causes it to fall back to the base of the tank. The effluent obtd. is free from floating matter and a satisfactory degree of purification results.
