Title: Glass or plastics article conveyor - has ascending auxiliary conveyor leading to railed level with storage belt
Inventor: BATHELLIER LOUIS
IPC: B65G47/51
Filed: 1974-08-02
Abstract: The main conveyor carries the objects from one station to the next. Should there by any hold up in the flow of objects, due to a breakdown at a subsequent station, the objects are diverted onto an ascending auxiliary conveyor which transports the objects onto a raised level where they are transferred onto a storage belt. The storage belt is made up of several parallel sections, so that each section may be filled to capacity before the next one starts taking objects. When the hold up is cleared, the conveyors may be reversed and the objects reintroduced into the main stream.

Title: Press. regulating valve for double circuit brakes - has double seats with control pistons responsive to press. in one line
IPC: B60T8/18
Filed: 1974-11-27
Abstract: A brake force regulator responsive to vehicle loading supplies compresses air to the lower face of the spring loaded control piston (20) via inlet (16) during braking. The piston raises a tubular extension (22) so an annular valve lip (23) is removed from a valve disc (25) which is spring loaded upwardly. The valve can then adjust the pressure in the line to the front brakes using the piston (26), which has a second seat (24) for the valve lip (23), and the force regulator pressure on the annular face of the piston (26) in chamber (48). The lip (43) of the valve disc (25) slides on the stem so the double seat valve (23, 24, 25) will be discharged of pressure.

Title: Carding device rotary element co-operating with non-rotary element - adjustably mounted on support by three fixing elements
IPC: D01G15/08
Filed: 1974-11-06
Abstract: A carding device includes a rotary element which cooperates with a non-rotary element to advance the fibre lap. The non-rotary element is mounted by a row of at least three fixing elements spaced equidistantly across the widths of the device on a support, and at least one of the fixing elements is adjustable to allow adjustment of the position of the non-rotary element relative to the rotary element. Flexing of the non-rotary element is reduced thereby ensuring a uniform nip between the rotary and non-rotary elements across the width of the device. The width of the nip can be accurately adjusted thereby eliminating the necessity of accurate machining of the rotary and non-rotary elements.

Title: Small-scale sewage treatment - by aeration through immersed splash wheel combined with radial air flow impeller
IPC: B01F3/04
Filed: 1974-12-23
Abstract: A small-scale sewage treatment plant of parent patent is based on aeration by spraying uses a splash wheel with blades dipping into the sewage which is arranged on a vertical drive shaft in a stack above the fluid level. A fan impeller above the splash wheel discharges the atomized fluid in a horizontal direction. The appts. is improved by combining the splash wheel with the fan impeller, the latter being a radial flow fan, with downward extensions which dip into the fluid level. An annular plate covers the top of the fan impeller except a central part. The design is thus simplified and the direction of the expelled air flow coincides with that of the fluid droplets, resulting in a more intensive mixing and aeration.

Title: Automatic parallax compensator for stereo map plotters - permits use of fixed raster sensors without needing a computer
IPC: H03K7/06
Filed: 1975-02-27
Abstract: Two images are scanned by sensors connected to a common correlator through separate storage devices to determine the relative time displacement of two image signals. The sensors and the correlation are connected to a discriminator to analyse the error voltage produced by the correlator, whereby both sensors are controlled by a generator and the correlator produces the parallax signal by comparing the two image signals. The sensors are light-sensitive solid-state detectors, and the discriminator is connected to each sensor through a scan control unit and the storage device. The control unit is pref. a voltage-dependent oscillator which corrects the scan signals from the storage device in each case.

Title: Data processing unit with programme modules - modules permit repeated cycle operation without increase in main memory capacity
IPC: G06F9/40
Filed: 1975-04-16
Abstract: A data processing unit employes a programming system based upon a number of small programming blocks that are linked together within a main routine. This enables the programme blocks to be recycled if necessary to return it to the start condition. Auxiliary memories associated with end programme module enable this facility to be realised without resulting in an undue increase in main memory storage capability. The main memory store operates together with the auxiliary memory modules and bit memory all of which communicate with the central control unit over data bus bars. The eight bit data words are transferred to six registers and a register selection block. The auxiliary memory provides intermediate data storage necessary for returning to the start of a programme block.

Title: Press tool for thick walled components - has two opposing rams to prevent cracks in component bore
IPC: B21J5/10
Filed: 1975-05-27
Abstract: The machine arrangement uses an additional ram which exerts axial and opposite force to the direction of emergence of the pressed component. Axial pressure against the bottom of the cylindrical component can be exerted by a hydraulic fluid. This axial opposing force can be increased over the pressing process or exerted only within the period in which the danger of the surface shear crack formation exists. The blank (3) is placed into the cylindrical die (2) and the working ram (4) and axial support ram (5) are brought into contact with. The metal of the blank is displaced by the ram and against the cylindrical die and the displaced material exerts pressure on the axial support.
