Filed: 1957-10-24
Abstract: 873,150. Valves. SWAIN, F. E. Oct. 22, 1958 [Oct. 24, 1957; Dec. 3, 1957], Nos. 33169/57 and 37579/57. Class 135. In a butterfly valve comprising a butterfly closure member mounted in a valve body for rotation about an axis inclined to the plane of a radially expansible seating ring mounted in a valve body recess for engagement with the periphery of the closure member in the closed position of the valve, the closure member which comprises a cylindrical boss 2 fixed to an operating shaft 3 and an integral circular valve plate 1 with a part-spherical sealing edge, angularly disposed in relation to the axis of the shaft, is transversely movable in the valve body by rotation of a lever 10 to move a screwthreaded rod 8 into and out of abutting relationship with the end of the shaft 3. On moving the rod away from the shaft when the valve is closed, the closure member and shaft are moved bodily towards the rod by a component of the fluid pressure acting on the upstream side X of the valve plate and owing to the floating nature of the seating ring 3 and the angle between the shaft axis and the valve plate the valve plate moves into tightsealing engagement with the seating ring. To open the valve the rod 8 is moved into abutment with the shaft 3 so that the centre of the valve plate 1 is moved to coincide with the centre of the ring 3. The lever 10 and rod 8 may be replaced by a fluid-operated ram or the shaft 3 may be screw-threaded so that on rotation of the single lever 7 the closure member is moved transversely besides being rotated. Specifications 753,860 and 843,845 are referred to.

Abstract: 1292168 Continuous filtration process H MULLER 9 July 1970 [9 July 1969] 33498/70 Addition to 1056321 Heading B1D Viscose solution is filtered through a filter medium formed from a regenerable granulate of polyvinyl chloride supported on a horizontal filter surface, the polyvinyl chloride being a mixture of particles of two separately produced emulsion or suspension polymerised vinyl chlorides, one of which consists of particles substantially all of which have sizes between 15 and 100 microns whilst the other consists of particles of between 80 and 200 microns. After filtration the polyvinyl chloride particles are passed to a wet classifier 1 for removal of coarser impurities, e.g. swelling materials, fibres and dirt. The particles are next withdrawn via screw pump 2 and led to flow classifier 3 for further cleaning. The cleaned particles are led to vessel 5 which acts as a hydro-cyclone, fine particles being led upwards and eventually outwards to container 6, whilst larger particles sink and are led off to vessel 8. Vessel 8 contains viscose solution awaiting filtration, and the added particles act on a filter aid. Vessel 6 forms the supply vessel for precoating tank 9 from which particles are drawn to coat the filter surface.

Title: Improvements in apparatus for separating sheet-like articles from a magazine
IPC: B65H3/08
Filed: 1963-08-28
Abstract: 1,100,021. Feeding sheets. STILEX PRINTING Ltd. and R. V. BAYLISS. 28 Aug., 1964 [28 Aug., 1963], No. 34081/63. Heading B6B. Pile tables and sheet separators.-Apparatus for feeding sheets or sheet-like articles of paper or metal to the working station of a printing or other machine comprises a magazine 274 for the sheets, pivoted about a shaft 262 and secured in a suitable position by the engagement of bolt 276 in slot 277, which is concentric with the shaft 262, in a fixed quadrant 278, and the sheets are extracted from the magazine by oscillating suction arms 264 which are pivotally secured to the shaft 262. The invention is described as applied to a screen printing machine disclosed in Specification 995,006. The magazine 274, which can be adjusted towards or away from the machine bed by means of the bolt 276, supports the sheets by feet 275 on the bottom of its frame members. If, however, the magazine is swung clockwise through about 180 degrees, the stack of sheets is urged upwardly against the feet 275, and the sheets will be separated from the top of the stack. An arm 257, oscillatable about a fixed shaft 256 by means of an hydraulic cylinder device 258, is fixed to a quadrant 259 having an arcuate surface 260 in frictional engagement with a roller 261 fixed on the shaft 262. Two arms 264 carrying suction heads for separating sheets from the magazine are secured to the shaft 262, and air passages in the arms are connected to flexible pipes 269 through rotary valves on the shaft 262. The pipes 269 are guided about pulleys 270 riding in a slot 272 in the machine frame. Thus, when the cylinder 258 is operative, the roller 261 and shaft 262 are rotated, first clockwise and then counterclockwise, by the quadrant 259, and the two suction arms 264 swing upwardly to seize a sheet, and then downwardly to deposit the sheet on a feed table. At the two extremities of the stroke of the suction arms, slip occurs between the roller 261 and the drive surface 260 when the arms meet resistance. Registering and forwarding sheets.-Each sheet is deposited on a support comprising a central narrow suction carriage Y, adapted to be recipocated to feed the sheet to the printing station as described in Specification 995,006, and two suction frames (251, not shown) disposed one on each side of the carriage. The carriage Y has suction established thereto, and moves backwards to register the sheet against a rear stop, and the two suction frames then grip the sheet, and are moved by an hydraulic cylinder device transversely to register the sheet against a side stop. The registered sheet is then fed forward by the suction carriage Y to the printing station.

Title: Digital data recorder with multiple input terminals
IPC: G06F11/00
Filed: 1970-07-14
Abstract: 1314204 Data transfer MOHAWK DATA SCIENCES CORP 14 July 1970 [15 Sept 1969] 34182/70 Heading G4A A digital data transfer system for transferring a message from any one of a plurality of message input terminals KB1-KB3 to a single message processing station TU comprises a transfer memory MUX including a polling means for periodically transferring polling requests to the terminals to initiate data transfer from terminal to memory, means for indicating the presence of a message in the memory, means for generating a message demand at station TU, means for transferring a message from the memory MUX to the station TU, means for blocking the polling means while the transferring means are operating, and means for actuating the transferring means only when there is a message in memory MUX and a message demand from TU. This is used in transferring keyboard entered data to a magnetic tape or disc. Operation.-An operator enters digital data at a keyboard with verification into its associated buffer memory KBL1-KBL3 which accumulates a message block of 80-100 characters. Apparatus for loading and verifying is disclosed in Specification 1,305,057. The polling means scans the buffers KBL1-KBL3 in sequence and, when it finds a completed message, causes it to be transferred to memory MUX in parallel. This continues until the tape unit TU requests a message when, if there is a message or messages stored in memory MUX, polling is ceased, the keyboards cannot enter new data, and messages are transferred to the tape unit on a first in first out basis a block at a time. When transfer to the tape unit ceases, polling resumes again. At the tape unit the messages are transferred to a tape unit memory whence they are immediately recorded by a record head. Error detection.-A read head is provided one message length down the tape so that, once the message has been recorded, it is read again and compared bit by bit for accuracy with the data still in the tape unit memory. If an error is detected a further message to the tape transfer is blocked, to the memoery MUX is filled up then polling is ceased until the error is removed. A supervising operator must do this. An erase head is available in case of error and a further erase head above the write head deletes old data. Keyboard to multiplexer accuracy is vertical and longitudinal parity checked and a terminal identifying character is added to the message so that the keyboard operator can be notified of error. If an error is detected, retransmission is initiated, and, if this fails, the operator is notified by an alarm and the message must be rekeyed. This is optional though. If an error is detected in transmission between the memory MUX and the tape unit memory, retransmission is effected and if this fails, the operator is informed. The multiplexer includes serial data transfer using a shift register, polling counter, and visual displays of the terminal origins of the messages stored in MUX. The tape unit is also described (Figs. 3f to 3i).

Title: Improvements in or relating to methods of manufacturing thermo-electric devices
IPC: H01L35/34
Filed: 1961-09-25
Abstract: 979,715. Thermocouples. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 25, 1961 [Sept. 28, 19601, No. 34237/61. Heading H1K. A series connected assembly of thermocouples is made by sandwiching spaced rods alternately of different thermoelectric materials between two electrically conductive members provided with a pattern of apertures or other non-conductive parts, and dividing the sandwich assembly along lines perpendicular to the rods to provide rows of interconnected slices of the rods. The pattern of non-conductive parts is such that after division alternate pairs in one row are interconnected via one member and the intervening pairs via the other, while in the adjacent rows the intervening pairs are interconnected via said one member and the alternate pairs via the other. Each member may be a copper or aluminium plate with a pattern of holes punched, sawn, milled or etched therein, an aluminium plate with a pattern of oxidized patches, or a member of insulating material with a conductive pattern formed on it through a mask or by attaching thin conductive sheets or strips to it. In certain cases the non-conductive pattern may be formed in the plates after attachment to the rods. The assembly may be subdivided by sawing or milling in one or more stages. Before, between the various stages of, and after subdivision any apertures remaining in the assembly are filled with hard setting resin. A typical assembly (Fig. 4) is made by soldering rods, alternately of N and P type bismuth telluride between two apertured plates, as shown in Fig. 3, the holes in the upper and lower plates being designated 17 and 19, respectively. The assembly is then subdivided by cuts 23 extending alternately from opposite edges to leave only the end rods and adjacent parts of the plates unsevered as shown. In this case the cross-sectional area of the end rods is half that of the others to equalise current density throughout the assembly. As an alternative the rods are of uniform size and the cuts completely sever the strips which are subsequently rejoined in the same relative positions by copper strips on the upper or lower face of the assembly. A cylindrical assembly is formed by essentially the same method but with the rods assembled between plates bent to form coaxial cylinders. The rods are either straight and parallel and the dividing cuts radial, or annular, in which case the cuts are perpendicular to the axis of the cylinders. The tellurides of bismuth, antimony and lead, and copper and constantan are mentioned as suitable materials for the rods.
