Title: Injection head for extrusion blowing of plas - tic tube
IPC: B29C48/10
Filed: 1969-03-14
Abstract: Injection head for extrusion blowing large diameter plastic tubes has a receptacle supplied with molten plastic along a central entry channel. An interior disc attached to the head is spaced from the rear wall of the receptacle by distance pieces distributed in uniform circular formation around the axis.

Title: Instant milk powder production
IPC: A23C1/04
Filed: 1969-12-22
Abstract: Thickened milk is thrown out of a first chamber into a second where it is spun into gaps between parallel rotating perforated discs. The product is thus separated into a light fatty low liquid fraction which is sprayed out into the drying chamber, and a second heavier non-fat and higher liquid content fraction which is also sprayed into the chamber in such a way that the two sprays collide, agglomerate and drop to the base of the chamber for removal as instant milk product. The separation into two fractions makes for a higher quality product, with assured agglomeration and grade.

Patent FR-2253885-A1 (FR)
Title: Method of forming concrete wall - involves using a lost shuttering panel able to be cut with hand tools
IPC: E06B1/60
Filed: 1973-12-05
Abstract: The walls of the shuttering are kept in position, by means of section which are encased in the concrete. One of the shuttering walls is made of rigid material possessing good thermal and sound insulation properties and is hard enough to retain the concrete yet thin enough for apertures or slits to be cut by hand tools. The windows and doors are formed by inserting sections into the aperture in the shuttering before the concrete is poured. The sections can be dismantled and are of about the same thickness as the width of the gap. The sections consist of two uprights kept in position by retractable jacks exerting horizontal forces, and a straight or curved horizontal piece on the uprights.

Title: Gantry for skip handling forklift truck - has columns action as tracks for roller mounted skip pivoting members
IPC: B66F9/02
Filed: 1974-01-23
Abstract: Two vertical columns act as tracks for intermediate pivoting members (8). These have pairs of rollers (11 - 14) running against opposite sides of the columns (16), and are joined to each other by the tipping axis of the skip and the stop bar against which it rests. At the top of the gantry there can be two motor driven winch drums (24, 25) from which ropes are reeved round pulleys near the bottom of the skip and between its tipping axis and the vertical plane of its centre of gravity and back to anchor points (28) at the top of the gantry. These hoist the skip until a stop prevents it rising further, whereupon they cause it to tip about its axis in relation to the pivoting members.

Title: Petrol economiser for vehicle engine - has spring attached to accelerator to increase resistance with throttle opening
IPC: B60K26/02
Filed: 1974-10-31
Abstract: A device for saving petrol and helping to maintain speed limits acts on the accelerator control to keep the driver informed of the position of the control, using the variation in resistance offered by the accelerator control throughout its travel. This variation is achieved by one or more springs (2) or a device giving the same effect, e.g. a rubber, pressure, vacuum or electric device. The spring can be fitted to the engine (1) and to the accelerator control (4), whether this is manually or foot controlled and directly or indirectly fitted to the carburettor.

Title: Automatic vehicle clutch with low and high speed clutches - has valve disconnecting low speed clutch above set clutch speed
Inventor: HATTORI TORAO
IPC: F16H61/16
Filed: 1974-12-13
Abstract: An automatic vehicle transmission has a clutch, operated by oil pressure, for high speed and another for low speed. These clutches are connected selectively by a switching valve to an oil pressure source. An automatic control valve (6) operates when the low speed clutch operates above a given speed. The valve immobilises the low speed clutch by putting the clutch interior oil pressure chamber in communication with its exterior and feeds oil under pressure to a pressure chamber in the high speed clutch to engage it. Sudden braking is a condition then catered for.

Title: Operational amplifier input circuit for disturbance suppression - attenuates effect of high frequency interference signals arriving at either inverting or noninverting input
IPC: H03K3/013
Filed: 1975-10-09
Abstract: An input circuit consisting of an arrangement of capacitances and resistances is for application to differential operational amplifiers, which attenuates the effect of interference or disturbance signals. The operational amplifier has two inputs, one inverting (3) and the other non inverting (2) and a disturbance pulse on one of these can lead to unbalanced conditions at the output (4). To avoid this the two inputs are coupled through a capacitance (7) of size determined by the amplifier and signal characteristics, so that any disturbance on one input, arising typically from power supply disturbance, is to a large extent offset by the application of almost the same signal to the other input. A network of resistances (8, 9, 10, 11, 13) completes the arrangement.
Patent FR-2330185-A1 (FR)
Title: Single phase multispeed asynchronous motor - has single capacitor and shared auxiliary phase subwindings to reduce costs
Inventor: DAUBAN HENRI
IPC: H02K17/08
Filed: 1975-10-28
Abstract: The single-phase multi-speed asynchronous motor has its winding divided into subwindings and a series capacitor that forms a common auxiliary phase for the main phases that give the various speeds. The subwindings are switched to the capacitor. The advantage of using a shared auxiliary phase in this way lies in avoiding the uneconomical use of separate windings and capacitors for each motor speed. The number of wires in the stator slots can be reduced and only one capacitor is needed.
