Title: Cover plate for window control rod groove - has serrated face on side which engages the plastic window frame
IPC: E05C9/18
Filed: 1974-03-11
Abstract: The plastic window frame (1) contains a groove (2) for control rods to pass through. It is necessary to close this groove by means of a metal cover plate (3). The cover plate is held in place by screws (4) which engage in a metal section (5) in the centre of the window frame. Owing to the unsupported length of screw in the groove (4') there is a tendency for the cover plate to slip. This is overcome by serrating the edges of the cover plate so that when it is tightened against the frame it embeds in the plastic and forms a tight fit.

Title: Programmable electronic signal controller - fully interlocked step-by-step controller with built-in jump facility when system malfunction occurs
IPC: G06F9/32
Filed: 1974-12-11
Abstract: A programmable step-by-step signal controller with output states fully interlocked with status signals, is based upon memory stages controlled by a clocked counter. The operation memory stage outputs decide if the next state required is to proceed. Impulse orders are generated and the pulses are stretched in conjunction with a latch. Stored outputs are called up from memory stage. The gating logic interprets the state of the operation memory as well as the output of a multiplexer and decides whether the relay is opened or closed to clock signals.

Title: Automatic control of vehicle steering - uses torque motor on steering control shaft controlled from programme unit
Inventor: BOSSER STEPHANE
IPC: B62D1/24
Filed: 1975-03-24
Abstract: Test equipments are available for testing such parts as vehicle tyres and suspension and for checking engine and clutch. Tests are required to take place on the road however the driver is unable to repeat exactly the previous test and conditions therefore automatic steering is indispensable. The steering control shaft (4) on a motor vehicle is driven in either direction by a torque motor in an electromagnetic unit (1) which is mounted on the shaft and connected to the vehicle body by a support bar (5). A potentiometer (6) provides feedback to a comparator (22) in a control unit (2) in order to compare steering position with the demanded position from a programming unit (21). The difference signal activates an amplifier (23) to drive the torque motor in the required direction. A power unit (3) supplies power to the control unit.

Title: Adjustable support frame for storage rack - has 'I' section arms cantilevering from 'I' section posts, using hooks and dowels
IPC: A47B57/52
Filed: 1975-06-23
Abstract: The adjustable and demountable support frame for a storage rack has vertical posts and horizontal arms (2) which can cantilever from either side. The members are all of metal 'I' section and the cantilever arms are fixed on the posts by a simple self-securing dowelling system. The cantilever arms (2) align transversely to the line of posts to support longitudinal shelf carriers. The posts are positioned with webs normal to the rack line and the cantilever arms fix to the flanges (5). The fixed end of each cantilever arm has two hooks (12) and two dowels (10). The hooks (12) are sited at the top of the arm (2) section and engage the post flanges (5). The dowels (10) are sited at the base of the arm (2) section and enter holes in the post flanges. The cantilever moment thus holds the dowels in the plate.

Inventor: CRUTSCH LOUIS
IPC: B61L5/10
Filed: 1976-01-23

Title: Lift acceleration control system - on short journeys continues acceleration beyond predetermined deceleration point to suit distance covered
Inventor: LEHNERT HELMUT
IPC: B66B1/44
Filed: 1976-04-14
Abstract: The system regulates the cessation of acceleration of a lift, partic. lfor journeys which are too short for it to reach full lrated speed. On such journeys acceleration continues beyond the predetermined deceleration point. The point at which acceleration ceases and easing-off takes place prior to braking is calculated from the distance covered and the increasing speed. From the starting point to commencement of deceleration lthe actual cage speed can be integrated with the time period, and a mean value determined from the distance covered and the predetermined fixed distance between deceleration point and stopping point. The deceleration analogue value is derived from the peak point represented by an electrical value. After equalisation of this resultant value with the analogue value of the time integral of the actual speed, the braking operation to the stopping point is effected by a predetermined desired-value function.

Title: Shaping the surface of plastic foam article during moulding - by passing air flow over the surface
Inventor: BEKEFI OTTO
IPC: B29C39/42
Filed: 1976-05-26
Abstract: A plastic foam article is moulded in an open mould and during foaming an air flow is forced across the surface of the foam in a direction transversely of the side walls of the mould. The air flow counteracts or compliments the other forces acting on the foam, e.g. expansion force, friction, gravity and can be adjusted or deviated as required to produce the desired shape of surface (e.g. flat, curved).

Title: Safer acetylene storage bottle - having layer of decomposable material above normal packing preventing gas decomposition
Inventor: BOLINGEN ERNST
IPC: F17C11/00
Filed: 1976-09-06
Abstract: Compressed gas container for potentially explosive gases contains a packing of porous material above which is a layer of a second material near the bottle outlet, this being distinct from the main packing. This consists of an organic or inorganic salt or salt mixt. which decomposes thermally. It can be a support with such a salt on it. The bulk of the packed space can be a conventional support with a known salt on it and only the top space need be filled with the salt described. The upper layer can consist of a light, porous, carrier material, esp. leaf mould into which the salt is impregnated. This material should have a lower density than the material filling the bulk of the container. Esp. for the storage of acetylene under press. The salt decomposes and removes the heat from the decomposing acetylene, thus quenching the reaction. With protracted used, settling and attrition of the packing occurs and an explosive condition can arise in the empty space which develops above the packing.

Title: Filtering gases contg. very fine particle e.g. of iron oxide - with precoat of coarse particles formed on external walls of filter sleeve to prevent silting up
IPC: B01D46/02
Filed: 1976-12-08
Abstract: Filtration of a gas contg. very small solid particles of microscopic and sub-microscopic size is described. The filter appts. comprises sleeve or pocket filters through which the gas passes, an inlet for the gas, an outlet for the purified gas and a hopper for the collection of the solid particles. Coarser particles are introduced in such a way that they form a layer on the external walls of the filter sleeves, preventing the silting up of the filter cloth by the small particles and the subsequent pressure loss across the filter. Used to filter the gas being emitted from a chamber in which such operations as the use of a blowpipe on steel ingots and the cutting a metal sheets with an oxygen flame are being carried out. These operations produce iron oxides of 0.01 to 5 mu particle size. The filter allows the evacuation of the gas into the atmos. The build-up of a precoat to prevent the silting up to the filter cloth reduces the loss of gas pressure across the filter.

Title: Practice-type 20mm cartridge - is empty of propellant with projectile lengthened and hollow to maintain weight and balance
Inventor: BERGES PIERRE
IPC: F42B8/08
Filed: 1976-12-17
Abstract: The dummy 20 mm bullet has a case (1) which is emptied of propellant. A stopper is used to replace the primer in the base (8). The case is crimped to the projectile (2) in the usual way (5), and can be steel or brass. The base is lengthened by 44 mm and is made of steel.
