Title: Hydraulic flow rate control - for hydraulically operated elements in injection moulding machines
IPC: B29C37/00
Filed: 1974-07-31
Abstract: In an appts. for controlling at a value selected from a series of predetermined values, the rate of flow of a fluid to >=1 working element in the hydraulic circuit of a plastic injection moulding machine, in which the hydraulic circuit comprises several sources of fluid under pressure operating at constant delivery, each of which is interposed between a fluid collection reservoir and a manifold feeding the working element, the novel feature whereby (a) each source is provided with >=1 discharge valve capable of discharging the fluid delivered by the source into the collection reservoir for this, (b) each discharge valve has a mobile element designed to open or close the valve, operated by signal emitted by a control and operating unit, the predetermined values of the rate of delivering being combinations of the open or closed states of the various discharge valves. Provides greater flexibility of operation than the usual system of calibrated, but fixed area orifices. Changes in flow rate can be made during operation, and avoids the need for all the pumps to operate at considerably higher pressure than that used in the moulding machine.
Patent FR-2240357-A1 (FR)
IPC: F02D3/00
Filed: 1974-08-06
Abstract: A diaphragm-controlled pressure control valve assembly is provided, especially for fuel injection systems in internal combustion engines, in which a measuring member, disposed within the suction tube, is moved by aspirated air against a resetting force. The resetting force is supplied by a pressurized fluid, delivered through a pressure line, which continually acts upon the measuring member. The pressure, which is normally constant, can be arbitrarily changed by pressure control valves. At least one of the pressure-control valves is embodied as a flat-seat valve in which the pre-load of its movable valve member can be changed in dependence on parameters. The movable valve member is constituted by a first diaphragm on whose side pointing away from a fixed valve seat there is disposed a second diaphragm in positive contact with the first diaphragm. The second diaphragm is preferably provided with a relief bore. In a preferred embodiment, two pressure-control valves of similar construction are provided, each including two diaphragms.

Title: Precast permanent shuttering for columns and walls - has blocks capped by members of identical section to support plinth
IPC: E04B2/86
Filed: 1974-10-08
Abstract: The precast permanent shuttering for columns and enclosing walls can be used for both straight and curved walls. The shuttering consists of precast blocks resting on a precast at plinth. The upper part of the blocks is capped with an element of identical section to the plinth which reduces both manufacturing and storage costs. The plinths are longitudinal and L-shaped, with the blocks resting on the horizontal part of the L and butting against the vertical part, thus preventing the blocks from moving under pressure of the concrete. The inside faces of the blocks are corrugated to allow for better adhesion of the concrete.
Patent FR-2296700-A1 (FR)
Title: Metallic coating for ceramics made of pure alumina - using mixt. of niobium and yttrium oxide powders plus vacuum sintering
Inventor: DELVAL GERARD
IPC: C04B41/51
Filed: 1974-12-31
Abstract: Metallic coating for ceramics containing more than 99% alumina and which are virtually free from a vitreous phase, the novelty being that the coating consists of a mixt. of niobium and yttrium oxide Y2O3, using i-7 wt. % Y2O3 in the coating. Pref. Nb powder and Y2O3 powder are mixed and suspended in an organic binder, the substrate then being coated with the suspension, followed by heating the coated object in vacuum at 1650-1800 degrees C for 10-60 minutes. Used e.g. in mfg. electronic valves using ceramic and metal, esp. microwave tubes, and in thermo-electronic converters where the emitter is insulated from the collector. A good bond is obtd. between the metal coating and the alumina due to the use of the Y2O3 in the coating which diffuses into the alumina.
Patent FR-2263969-A1 (FR)
Title: Continuous changeover of paper feed rolls - involves adhesive bonding replacement feed roll to moving strip without reduction in feed rate
IPC: B31F5/00
Filed: 1975-02-24
Abstract: A high speed feed mechanism for paper from rolls provides interrupted motion while the rolls are bing changed. The feed rolls are mounted on shafts supported from the main machine body. The stationary roll has the leading edge of the paper inserted into a guide block that is mounted on a swinging arm pivoted at the top end. The guide is mounted on a guide pin and is free to move vertically. For change-over the swinging arm is moved horizontally by a cylinder bringing the paper end into contact with the moving strip. An adhesive strip is located between the paper surfaces. Immediately the bond is made the paper from the new roll moves with the same velocity as the existing feed. This is made possible by the guide block moving vertically for a short distance.

Title: Cover locking device for record player deck - operated in dependence on position of tone arm
IPC: G11B19/02
Filed: 1975-11-17
Abstract: The record player deck has a cover (11), which is automatically locked in the closed position, during reproduction of signals from a record disc placed on the turntable, by using the position of the tone arm (17), which is movable from a rest position at the side of the turntable horizontally across the surface of the record during play-back, to operate the locking device. The cover (11) is released by depressing a release button which is selectively coupled with the catch release for the cover, in dependence on the position of the tone arm so that the depression of the release button when the tone arm is in the play-back position does not cause the catch to release.
Patent FR-2334026-A1 (FR)
Title: Piston ring to reduce oil consumption - has outer concave surface forming sealing and scavenging edges (BR 10.8.76)
IPC: F02F5/00
Filed: 1975-11-24
Abstract: The advantages of this piston ring design are that it improves gas sealing and reduces oil consumption in any piston driven engine. These are ached by making the face (10) of the ring in contact with the cylinder wall (4) concave. The concavity may take the form of a shallow curve or may be derived from the intersection, on the ring median plane, of two shallow angled cones. In either case, the upper edge (7) of the ring provides a good gas seal when the piston is rising in the bore and the lower edge (8) scavenges the oil from the cylinder wall when the piston is falling. The ring is otherwise similar to a standard piston ring, having parallel sides (5, 6) fitting closely in a groove in the piston (3).

Title: Programme control of process cycles - has programmed memory containing processor instructions
IPC: G05B19/05
Filed: 1976-05-12
Abstract: The programme controlled system for process applications uses a bit processor for operation of peripherals requiring a single bit order and a word processor for peripherals requiring a coded word of information. A digital word processor (WP) is coupled over an interface bus (DS) with standard peripherals (STP) such as page memories, displays, tape etc., process peripherals (PRP) such as multiplexers, D/A converters etc. and also any associated processor (VER). A programme memory (PSP) couples over the bus with a co-ordinate (KOR) tied to the bit processor (BP). The bit processor (BP) connects with an interface bus and communicates with single bit output peripherals (BA), bit memory (BSP) and bit input peripherals (BE). The programme memory (PSP) holds both the instructions for the word and bit memories alternately and enables the fast operation of the bit processor to be fully utilised.

Title: Rapid text composition system - mounts modules containing data in stacks on surface folding back unwanted sheets
IPC: G03F1/90
Filed: 1976-07-01
Abstract: The rapid composition system is particularly for the production of generic texts with headings. Zones on a surface are selected to match the final presentation required of selected headings, and modules are mounted on these zones giving various information according to the headings, forming a folding stack of separate sheets. The required information is then selected from the different modules, and the individual sheets in the stack above that carrying the selected information are folded back. The mock-up thus prepared is then delivered to a reproducing unit. There may be a transportable support with zones accommodating the individual data modules, corresponding to a calibration along one or more of the support main sides.
