Title: Multichamber filter plant - has fluidics flow switch over to clean filters in turn
IPC: B01D46/02
Filed: 1972-03-07
Abstract: A filter plant comprising a number of filter chambers possesses a fluidics valve on the inlet side, leading to a pair of ducts which each discharge into a separate filter chamber; when a switch over device is actuated, the incoming flow is diverted from one of these ducts to the other, so that the filter material in the chamber associated with the first duct is bent to clean it. Each filter chamber pref. contains a number of suspended tubular filters, and, in addition to bottom inlet and top discharge ducts, has a bottom hopper discharge for dirt. The use of the fluidic principle to change the medium flow simplifies the layout and minimises the number of moving parts.

Title: Wood protection - against insects and microorganisms
IPC: B27K3/10
Filed: 1972-03-13
Abstract: The treatment is effected by driving hollow pins into the wood to be protected; these pins have an internal cavity which is in communication with the external wall of the pin by small orifices. The cavities are filled with an insecticide or a fungicide which diffuses progressively into the wood. The pins may be driven into the wood by any known means, such as compressed air or by the energy produced from the explosion of a cartridge. More simple means can be used, such as by hammering after drilling a pilot hole. The head of the pin is connected to any device that will introduce the liq. under press. into the cavity and keep it there for a sufficient time to allow it to diffuse into the wood. The treatment is very simple, the pins can be placed in the wood so that the visible portion does not constitute any aesthetic drawback. The cavity in the pin is sealed with a rubber plug; the liq. is introduced through a hollow needle which is pushed through the plug. This seals itself when the needle is withdrawn, thus retaining the liq. inside the pin.

Title: Electronic information display and storage device - has an array of microchannels using secondary electron emission
IPC: H01J31/36
Filed: 1973-10-19
Abstract: The device has an array of microchannels (11) placed in an evacuated container. The entry faces (13, 14) are metallised (15, 16) and connected through switches (17, 18) to a voltage source. When the switches (17, 18) are closed a difference of potential is applied to the faces (13, 14) such that the potential on the exit face (14) is higher than on the entry face (13). Another electrode (19) situated opposite the exit face (14) is at a higher potential than the exit face. Due to the difference of potential between the two faces (13, 14) and because the electrons are subjected to secondary emission and multiplication before being attracted by collector electrode (19), positive charges give a spatial distribution corresponding to the spatial distribution of the electrons, and thus provide an electronic image.

Patent FR-2289749-A1 (FR)
Title: Starting device for IC engine carburettor - has solenoid holding auxiliary throttle control diaphragm in operating position
IPC: F02M1/10
Filed: 1974-10-31
Abstract: Auxiliary throttle is connected by a link to a lever on a spindle which also carries a lever. The end of this lever fits in the slot of a rod attached to a diaphragm loaded by a spring. A solenoid is energised through the engine ignition circuit but is unable to overcome the spring. On starting the engine the vacuum in the carburettor is transmitted to a chamber and overcomes the spring so that the rod moves and opens the auxiliary throttle. The solenoid can then retain the rod in its operating position and a bimetallic spiral controls the position of the auxiliary throttle.

Title: Cast metal tube with glass liner mfr. - by injecting glass powder into the hot freshly cast metal surface
Inventor: BARTON JAMES
IPC: C23D5/04
Filed: 1975-01-16
Abstract: Method of making a tube or tubular article in centrifugally cast metal esp. iron internally coated with glass comprises projecting glass powder onto the iron immediately after casting while the centrifuge is still rotating with the mould. The process combines two processes one one machine, viz. casting and glazing without the expense of tooling up for the glazing and subsequently fixing operation or the cost of heating for glazing, since it uses heat from the casting process before it is dissipated. The product is remarkably free from bubbles in the glass which adheres well to the metal and shows a smooth surface. It exhibits high mechanical strength and abrasion resistance.

Title: Sealing ring for hydraulic or pneumatic circuits - is made from band of pre-impregnated textile fibres
IPC: F16J15/56
Filed: 1975-02-04
Abstract: The method of making a sealing ring, consists of impregnating natural or synthetic textile fibres in an elastomeric or plastomeric solution, then making a band from these fibres, esp. by braiding, then forming the band to a ring and pressing it. Pref. the ring is formed by superimposing several layers of the band e.g. in helical form. The band itself may be impregnated with a substance compatible with the impregnating agent. The first impregnating soln. may be of such a concn. that the band material, when immersed in a liquid, possesses a specific swelling capability, or zero swelling capability. The process is simpler than cutting the ring from fabric.
