Title: Paste or liq. distributor pump - has hollow piston with button sliding in body at base of reservoir
IPC: F04B9/06
Filed: 1975-06-18
Abstract: The pump is for mounting in the lower part of a distributor unit dispensing metered quantities of pasty or liquid material. It has a main body fixed in the bottom opening of a reservoir containing the product, and a hollow piston sliding in a bore at its lower end. An actuating button is fixed to the lower end of the piston. A valve inside the piston comprises un upper plunger sliding in a bore in the latter, and a needle whose free lower end works against a seat in an ejection port at the lower end of the piston. The needle is spring-loaded against the seat. An annular discharge joint slides between the main body and the piston. A main return and support spring acts between an upper shoulder in the main body and a stop on the piston.

Title: Rehydration of dried vegetable and fruit prods. esp. mushrooms - by siphoning via controlled duration vacuum and soaking
IPC: A23B7/148
Filed: 1975-07-17
Abstract: Prod. is entrained in water which is siphoned from a feed tank level, via an intermediate higher level down to a lower delivery tank level. A vacuum pump is connected into the siphon passage. The vacuum chamber is fitted with means to control the rate of throughput of the solid product so that it is slowed down with respect to the unrestricted flow of water. The vacuum chamber is pref. a horizontal, cylindrical vessel with an axial screw conveyor to regulate prod. flow Delivery from the vacuum chamber outlet leg is pref. into reception tank which ensures that the prod. will be held in water for a controllable period, partic into a pocket of a mult-pocket submerged rotor which has to make a complete revolution to bring the loaded pocket to the outlet port of the reception tank. Introduction of a vacuum chamber permits the use of much more powerful vacuum forces, e.g. 10-20 torr. The vacuum chamber conveyor can retain the prod. under vacuum for any selected duration, e.g. 5 mins. The reception tank can likewise retain the prod. for a long soaking period, e.g.>=1 hour.

Title: Deaeration valve for plastics sack filling - has welded strips with gap communicating with sack interior and closed afterwards by welding
IPC: B65D77/22
Filed: 1976-01-16
Abstract: A plastics sack incorporates a valve which allows air to be sucked from the interior while it is being filled, so that there are no air pockets left, and which is easily sealed by welding afterwards. The wall (1) of the bag has a set of perforations through it which match a corresponding set of holes in a plastics sheet (14') forming part of the valve. This valve consists of two plastics layer (14, 14') which have been previously welded together along two lines (7, 8) one end. The first sheet (14') is welded over the perforations by a ring shaped weld (16), then the remaind of the two sheets are welded together at that end by a c V shaped (20), so that the only communication, which the interior of the bag through the perforations, is between the parallel welds and the open end (21) remote from the perforation.
Patent FR-2344935-A1 (FR)
Title: Rotary target-carrier for obtaining intense neutron flux - of simple construction, with simple cooling, admitting several particle beams
IPC: G21K5/08
Filed: 1976-03-15
Abstract: Appts. simultaneously bombards a target with several beams of accelerators and produces an intense flux of neutrons. In the prodn. of neutrons, a tritium-contg. target is bombarded with deuterons. The targets have a metallic support on which is deposited titanium alloyed with tritium by diffusion. The appts. incorporates a rotary target-carrier which allows several beams of particles to be used, so that the points of impact on the target are relatively close, giving a very intense flux of neutrons. The target is cooled by a liq. which wets the heat transfer metals well. The invention can be applied in all areas where intense neutron fluxes produced from particle accelerators are needed, e.g. neutron therapy, neutrongraphy, analysis by neutronic activity. The construction of the target-carrier and its method of cooling are simple.

Title: Hot pressing silicon carbide to obtain high density - using as additive a boride of silicon or aluminium, boron nitride or aluminium carbide
Inventor: BROUSSAUD DANIEL
IPC: C04B35/575
Filed: 1976-06-24
Abstract: SiC ceramic having a density of >=95% theoretical density is made with the aid of an additive selected from SiB4, SiB6, AlB2, AlB12, BN or Al4C3, used in amt. 0.5-5 wt.% w.r.t. the wt. of SiC. The SiC ceramic is prepared by forming a homogeneous dispersion of 3 mu dia particles of SiC and the chosen additive (10 mu particles) and heating the dispersion to bring the density to the desired value, pref. under a pressure >=250 kg/cm2. and in a neutral atmosphere, at 1900-2100 degrees C for 5-30 mins. Process is less expensive than prior art since particles larger than 1 mu may be used, with consequent saving of grinding energy.

Patent FR-2338600-A1 (FR)
Title: Selective remote control for loads in buildings - uses separate signal wire carrying switching information with unique signal for each load
IPC: H02B1/24
Filed: 1977-01-11
Abstract: A ring main comprising a phase conductor, neutral conductor, and signal wire connects loads and controls together throughout the building or sections of it. The controls each generate a unique signal to which loads tuned to that signal will respond. The information may be transmitted by impulses, voltage level, phase displacement, or similar. The advantage of the signal wire system is the ease with which alterations to circuits and controls can be made. Each unit, control or load, contains an exchangeable plug-in signal element, thus merely by altering these elements the switching point or selection of loads can be altered without the need for access to the wiring. The system is also well localised and does not need mains filters or signalling appts.

Title: Door displaceable by pivotal and translational movement - has hinge plate between vertical hinges on jamb and door quarter point
IPC: E05D15/30
Filed: 1977-04-01
Abstract: The door(5) moves between the open and closed positions by a combined rotational and translatory movement with a hinge-plate(1) extending between vertical hinges (3, 6) on the door(5) and a frame post(4). The door hinge(6) may attach to the adjacent quarter point in the door width. The unlatched edge of the door, thus, moves perpendicularly to the door-opening as the leaf pivots. The arrangement reduces the projection of the door into a room to a demi-width, and is primarily for industrial usage. In addn. a mechanism is provided to guide the movement of the leaf. A runner(7) may be provided on a vertical axle (10) which projects from the head(12) of the door(5) at mid-width. The runner(7) slides in a track(8) which is built longitudinally into the head(9) of the door frame. Two pulleys wheels may be positioned on the head of the door and on vertical axles through the hinges(3, 6), the post pulley(3) being of a greater dia. and the pulleys being traversed by an endless belt.
