Title: Liquid sample collector device
IPC: B01L3/00
Filed: 1980-11-18
Abstract: A collector device for collecting, metering and holding a small sample of liquid, e.g. a drop of blood taken from a finger prick, comprises a vessel (10, 11 or 10A, 52A) provided with an opening (20 or 20A) closed by a plug (22 or 22A), and a screwthreaded cap (15 or 15A) having a protruding spigot (30 or 30A) which, when the cap is screwed fully onto the vessel, enters the opening and pushes the plug down into the interior of the vessel. The plug is formed at its outer end with an outwardly facing recess (24), e.g. part- spherical, and the spigot is formed at its end which enters the opening with a tapering conical formation (31) adapted to enter the recess (24). In use, with the cap (15 or 15A) removed the recess (24) is filled with a quantity of liquid, the cap is then partly replaced to cause the spigot (30 or 30A) to abut the end of the plug (22 or 22A) so that its conical formation (31) enters the recess (24) and displaces excess liquid therefrom, trapping a metered sample of liquid of predetermined volume, less than the volume of the recess, in the space defined between the abutted ends of the plug and spigot. The cap (15 or 15A) is then screwed fully home causing the spigot to push the plug down until it falls into the vessel, thus transferring the metered liquid sample into the vessel whose opening (20 or 20A) is now closed by the spigot (30 or 30A). The device enables a metered quantity of blood to be collected and transferred into the closed vessel for subsequent analysis, without contamination of the exterior of the device by the blood, and without the use of delicate metering devices such as capillary tubes to meter the blood sample. A latch connection (55A, 59A) may be provided between the cap (15A) and a removable lid (52A) of the collection vessel whereby when the cap is unscrewed it slowly withdraws the lid and opens the vessel.

Title: Procedure for manufacturing a plastics container
IPC: B29C43/56
Filed: 1981-02-27
Abstract: In the method a blank is formed and the blank shaped into a container by deep drawing or by another equivalent shaping process. The blank is formed between forming-surfaces (4, 5) movable relatively to one another, by introducing in the space (8) between the surfaces a sheet-like piece (1) of plastics, upon which a plastics material (13) is cast; the piece being cut from a sheet of the material. The blank thus produced comprises, depending on the structure of said sheet-like piece of plastics, two or more superimposed material plies. This optimizes the properties of the plastics container by combining different materials and, in relation to the prior method of forming the containers directly from a sheet of material, reduces the waste of material. <IMAGE>

Patent GB-2084916-A (GB)
Title: Improvements relating to percussive tools
IPC: B25D17/06
Filed: 1981-10-07
Abstract: A percussive tool incorporating a reciprocating driver piston and a striker 11 employs a pneumatic device for retaining the striker substantially immobile when it moves forward beyond its range of normal working movement. A vent passage 13 operates under working conditions to vent the forward end space of the cylinder but, when the striker moves forward under idling conditions, initially seals the vent passage to decelerate the striker, releasing the pressure in the cylinder end space through a recess 18 as the striker moves to allow communication between the recess and the vent passage. A small rearward movement of the striker causes this communication to be interrupted and a suction effect occurs, impeding further rearward movement of the striker. The suction effect is overcome when the tool is pressed against a work-piece. <IMAGE>
Patent GB-2087692-A (GB)
Title: A method and an apparatus for image processing
IPC: H04N1/415
Filed: 1981-10-07
Abstract: In a high speed image transmission system such as a facsimile system the redundancy of an image data source is reduced for transmission, and the error rate of an analog transmission system is improved by combining a synchronizing signal of a plurality of bits with a skip signal of a plurality of bits, the latter being substituted for an all white block. Errors in received images due to transmission line distortion are eliminated by first transmitting from a transmitter signals of high level for a predetermined number of bits and then signals of zero level, and by checking at a receiver the received signals every predetermined number of bits. When there is a picture signal immediately after a skip signal, a guard band signal is interposed between these signals but when one skip signal succeeds another, the guard band signal is not included, thus allowing high speed transmission without degradation in image quality. When the picture signals are sampled, the picture signals are first demodulated to be converted into binary signals having first and second levels which are stored and are then sampled to provide reproducing signals, so that black (or white) data is not dropped, irrespective of the sampling interval. <IMAGE>

Title: Metallized-film Dual Capacitor
IPC: H01G4/18
Filed: 1981-12-09
Abstract: A metallized-film dual capacitor comprises a convolute winding (10) of a plain dielectric film (20) and a metallized dielectric film (48) which has metallization over both of its surfaces. A first metal-free margin extends the length of one surface of the metallized film, and a second metal-free margin (42) extends the full length of the other surface and at the other edge to the first margin so as to provide a margin at each lateral-end edge of the winding. A metal-free region (46) extends across one surface of the metallized film (34) so as to divide the metallization on that one surface into a first electrode (36) and a second electrode (38). A first termination contacts the first electrode, a second termination contacts the second electrode, and a third termination contacts the metallization on the other surface of the metallized film. The winding further includes at least one full turn of a third dielectric film (18) which extends beyond one edge of the winding so as to ensure separation between the first termination and the second termination. Additional turns of the plain film (20) are utilized as the protective outer wrap, thereby eliminating the need for a separate outer wrap. <IMAGE>
