Title: Films of polytetrafluorethylene and process for making them
IPC: C08J5/18
Filed: 1968-10-14
Abstract: 1,240,883. Making polytetrafluoroethylene films. FARBWERKE HOECHST A.G. 14 Oct., 1968 [13 Oct., 1967; 12 Dec., 1967: 29 Dec., 1967], No. 48552/68. Heading B5B. Polytetrafluoroethylene film is manufactured by rolling pulverulent P.T.F.E. between rolls at a temperature within the range of from 100‹ to 325‹ C. to form a film and sintering the film at a temperature within the range of from 327‹ to 400‹ C., and preferably at a temperature of 350‹ C. The sintering step may be carried out continuously or discontinuously. In the former case the film is subjected to tension in the transverse direction. This tension may be applied at a moment at which sintering has reached such an extent that the tensile strength of the film in the transverse direction which has been increased by sintering are just sufficient to allow the film to be subjected to a transverse tension without the film tearing apart. The tension may be sufficient to stretch the film in the transverse direction. The film or sheet may be drawn in the longitudinal direction or in both the longitudinal and transverse directions. The film which has been preformed by the rolling step may be pressed by a travelling endless metal band with as large a wrapping angle as possible against a roll, the roll being maintained at the desired sintering temperature. The film may be in contact with the heated roll for about 20 seconds. As shown in the drawing, the unsintered preformed film of P.T.F.E. (1) may be conducted via a pressing roll (2) together with a travelling endless metal band (3) over a rotating roll 4 maintained at the sintering temperature and the film (1) thereby sintered is drawn off by the roll (5) and wound up. The endless metal band is kept under tension by the rolls 2, 5 and 6 and a fourth roll (unnumbered). When the sintering step is carried out discontinuously, the preformed film is coated on at least one side with an anti-blocking agent such as a powdered silicate, a liquid silicone or an inorganic carbonate), wound up to form a roll and then sintered.

Title: Automatic plastic sealed gate valve
IPC: F16K3/36
Filed: 1963-12-11
Abstract: 1,012,531. Valves. A. S. VOLPIN. Dec. 11, 1963 [Dec. 24, 1962], No. 48964/63. Heading F2V. A one-piece slide valve member or gate 19 movable between seats 18 by a rising stem 22 and having an opening 20 for fluid flow when in the open position is provided with reservoirs 43, 44 for a plastic sealant material. The reservoirs are charged from a point 56 or 66a, the sealant passing through a bore 51 in the stem to the space above a plunger 61 in the reservoir 44 and through non-return valves 63 to spaces above plungers 60 in the reservoirs 43. Welded to the stem is a yoke 35 which is attached to the gate by screws 40 in clearance holes so that the gate may move laterally in relation to the stem. When the valve is closed upstream pressure moves the gate slightly away from the upstream seat to gain access to the valve chamber 13 where it can act through holes 45 on the undersides of the plungers 60. The reservoirs 43 have holes 65 leading to opposite sides of the gate to register with an annular sealing groove 66 in each seat so that the pressure applied to the plungers 60 causes the downstream seat to be sealed. The seats have bores 70 for conveying sealant to rear grooves 67. The underside of the plunger 61 is also subject, through an opening at the bottom of the reservoir 44, to the pressure in the valve chamber 13 to supplement the action of the plungers 60 through the non- return valves 63. The sealant is also effective in a stuffing-box 27 and a housing groove 80. A ring 47 carried by the gate has packing 50 which allows the relative movement between the gate and stem without leakage of sealant. The gate slides in a shroud 72 comprising plates which serve as wipers for each side of the gate. A sealing collar 81 seats at 82 when the valve is open. In a modification, the stem 22 is bored to receive with clearance a relatively flexible sealant supply tube secured at its upper end to the stem and at its lower end to an element similar to the ring 47, and the reservoir 44 is omitted. The valve may be arranged-for flow in one direction only, in which case only one reservoir 43 is provided for sealing on one side only of the gate.

Abstract: 1535175 Fluid pressure servomotor MASSEY-FERGUSON SERVICES NV 17 Nov 1975 [18 Nov 1974] 49872/74 Heading G3P [Also in Division F2] A valve member (e.g. consisting of housing, cap and plunger 29, 30, 32) operates with a seat 27 to control communication between conduits 16, 17; fluid pressure in said conduits acting on the valve member urging it to open, there being a chamber 39, connected to one conduit by a restricted passage 45, fluid pressure therein acting to urge the valve member to close and a relief valve assembly 35, 36, 38 allowing flow from the chamber at a predetermined pressure so that reduced pressure in the chamber allows a housing 29 to move in the direction away from the seating 27 thus withdrawing plunger 32 and establishing communication between conduits 16, 17. Plunger 32 may also act as a non-return valve in conduit 16. The whole assembly of Fig. 2 may be installed in a pump/ motor system Fig. 1 at 20a 20b. Reversible pump 11 drives motor 19 and non-reversible pump 13 circulates fluid via pressure line 16, relief valve 24 and sump 14. Excess pressure in either of conduits 17, 18 may be released to conduit 16 via 20b or 20a in a pressure relief mode or, if pressure is excessively low in conduit 18, 17 respectively, be released via 20b in relief mode and 20a in non- return mode or vice-versa.

Title: Electronic picture display system
IPC: H04N7/12
Filed: 1965-11-24
Abstract: 1,107,360. Television. SOLID STATE ELECTRONICS PTY. Ltd. 24 Nov., 1965 [7 Dec., 1964], No. 50032/65. Heading H4F. The invention relates to a television system in which a broad band width television signal from a conventional television camera is transmitted over a narrow band width data link, e.g. a telephone line, and reproduction is effected by means of an ordinary television receiver having a long persistence phosphor adapted to receive conventional broad band width television signals. The broad band width signal is applied to a sampling gate which passes a short duration sample during each line, this sample being arranged to progress along the lines as each frame is transmitted so that different portions of each line of the broad band signal are passed in successive frame periods and substantially the whole of the image detail is transmitted by the end of a given number of frames. In effect only a vertical strip or preferably a horizontal strip (camera and receiver reorientated by 90 degrees) of the image is transmitted in each frame interval, successive adjacent strips being transmitted in successive intervals. Before transmission over the narrow band width data link the samples are quantized so that each sample has a black or white significance, i.e. the resultant signal indicates a presence (or absence) of an information bit at successive samples, and then integrated and filtered. At the receiver the transmitted signal is differentiated and re-sampled, the information bits corresponding with those originally sampled being progressively fed to the display tube of the receiver. The sampling gates at the camera and receiver are synchronized by means of a signal (frame sync.) comprising a pattern of consecutive black and white sample bits which is transmitted for a period of at least one active read time frame once every sampled time frame. In the camera the sampled information bits are converted into square waves having a duration of at least one line period by means of Schmitt trigger and multivibrator circuits before they are integrated. Similarly, at the receiver after differentiation the received signal is converted into square waves having durations of a line period by means of Schmitt trigger and multivibrator circuits before they are re-sampled. The quantized and integrated video signal and frame sync. are linearly combined with a modulated sync. carrier before transmission and separated at the receiver by means of a notch filter and a band pass filter. The camera may reverse the image black for white or white for black as desired and a switching circuit may be incorporated in the transmitter to limit transmission of the field of view of the camera to a portion only of the field.
