Patent GB-1380008-A (GB)
Title: Apparatus for monitoring the operation of a machine tool
IPC: B23B47/24
Filed: 1972-08-04
Abstract: 1380008 Machine tool control PRODUCTION ENG RESEARCH ASSOCIATION 13 July 1973 [4 Aug 1972] 36453/72 Headings B3B and B3C [Also in Division G1] An apparatus for monitoring the operation of a machine tool having an electrically conductive tool comprises means for detecting a thermal e.m.f. generated by operation of the machine tool, an electrical switching circuit, means for supplying a signal representative of said thermal e.m.f. from said detecting means to one input of the switching circuit, and machine function switching means for supplying a control signal to a second input of the switching circuit when the tool is required to be opreative, the switching circuit supplying an output signal only when the control signal is present at said second input in the absence of a detected signal. The cutting action may be turning, milling or a drill 6 held in a chuck 7 and operating on a workpiece 8, wherein a carbon brush 9 runs in contact with the chuck 7 and leads 11 connected respectively to the brush 9 and workpiece 8 carry the e.m.f. produced by the cutting action. The carbon brush 9 may alternatively be a slip ring or a spring loaded strip. The signal produced may be used to detect a broken tool, when the tool is cutting, or the load on the tool due to excessive feed, hard workpiece, or worm tool, and be used in a control apparatus accordingly. The signal may be used to give a visual display, e.g. by a voltmeter, or to stop the machine and ring a bell or flash a light. In a control apparatus (Fig. 1, not shown) a thermal e.m.f. probe (2) feeds an amplifying, filtering and rectifying unit 3 to produce a signal at (A) on a switching circuit (1) which produces the output control signal (C). To ensure that the apparatus is operative only when required in a machining programme, a direct current supply (4) operated by switches (5), e.g. by movements of tool slides &c., provides a second sginal (B) at the switching circuit (1) which is designed to produce an output (C) if input (B) is present without input (A). The inputs (A) and (B) may also be connected to a switching circuit (12) whose output (D) is received by a counter (13) for counting the operations performed or workpieces machined. The output (C) may also be connected to the switching circuit (12) to prevent a spurious or deliberately produced false count. To prevent overloading of a drill, the chuck 7 may have a torque slipping clutch, and the drill 6 may have a reduced section adjacent the chuck to ensure that if a tool breaks it breaks outside of the workpiece.

Title: Improvements in or relating to the production of slip-proof films
IPC: B29C48/10
Filed: 1963-09-18
Abstract: 989,323. Tubular films. SCHOLVENCHEMIE A.G. Sept. 18, 1963 [Oct. 3, 1962], No. 36806/63. Heading B5B. A tubular film made by the inflation process has a profile impressed thereon during the actual process, so as to render the finished film slip-proof. In the apparatus of Fig. 1, an inflated tubular film extruded from the annular nozzle 1 is flattened by the guides 2, heated if necessary by infra-red emitters 3, and then passed between the sealing and take-off rollers 4, at least one of which is profiled, e.g. in a honeycomb, chequered or grained pattern so that an embossed pattern is impressed on the film at a temperature lower than its softening point. The rollers 4 are adapted to be heated or cooled as necessary. Low-pressure polyethylene may be so embossed at temperatures of 50-125 C., especially 60-80 C. if a film of maximum strength is desired, or 110-115 C. for deep-drawn profiles. To prevent a notch effect along the folded edges of the film, the edge areas of the rolls are preferably free of profiling. In the apparatus of Figs. 2 and 3, the extrusion nozzle comprises an annular orifice 13 and an outer ring 12 rotatably disposed with respect to a circular array of bores thus sectioned. In operation, inflated tubular film extruded from the annular orifice is surrounded by an inner filament row extruded rectilinearly and an outer filament row extruded spirally, thus producing a meshwork 14 which bonds to the tubular film since both are in the thermoplastic range. The tubular film 15 is then flattened and withdrawn by the take-off rollers. Specified materials include low-pressure polyolefins, especially low-pressure polyethylene and poly propylene and polyvinyl chloride.

Title: Improvements in devices for switching transmission lines
IPC: H01P1/12
Filed: 1968-08-02
Abstract: 1,213,566. Mechanical switches. COMPAGNCE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 2 Aug., 1968 [2 Aug., 1967], No. 37096/68. Heading H1N. [Also in Division H4] A change-over switch for directly interconnecting (i.e., without any supplementary line section) both pairs of the four sections of two open-wire or coaxial H.F. transmission lines which cross at right angles in spaced parallel planes comprises at least two bridging conductors arranged in the form of an H with an insulating cross-bar, about the centre of which it is rotatable. The breaks in the lines and hence the lengths of conductors AB, A 1 B 1  and CD, C 1 D 1  (Pig. 3) are equal to the spacing d between the planes of the lines 1, 3 and 2, 4, so that rotaton through 90 degrees about axis 16 causes the conductors to interconnect line section 1 to section 2 and 3 to 4 (as in Fig. 4, not shown). To avoid parasitic coupling between lines a metal plate may be fixed to the cross-bar of the H, parallel to the bridging conductors. To avoid phase-correcting " twists " in the case of openwire lines, the sections are staggered, as shown, so that axis 16 lies at 45 degrees to each line. In the case of coaxial lines the inner conductors only are switched and one of these may be bent through 90 degrees as shown at 22, 23 in Fig. 6, the outer conductors preferably being of rectangular cross-section and arranged to enclose the whole assembly. In a practical embodiment for open-wire lines (Fig. 5, not shown) the wires terminate on insulators (17) supported on the horizontal members of an open rectangular frame while the axle (16) carrying the movable conductors (12a, 12b, 13a, 13b) is journalled in the vertical side members of the frame. In an embodiment using coaxial lines (Fig. 7, not shown) the H is rotated by a pneumatic piston and cylinder (25) and a metal screening plate (24) is provided with flexible contacts (not shown) to engage the outer rectangular conductors (19, 20, 21). A plurality of switches (Figs. 8 and 9, not shown) may be arranged to selectively interconnect a grid arrangement of crossing transmission lines (see Division H4).
Patent GB-785263-A (GB)
IPC: F16H61/02
Filed: 1955-12-28
Abstract: 785,263. Controlling change-speed gearing. DAIMLER-BENZ AKT.-GES. Dec. 28, 1955 [Dec. 27, 1954], No. 37137/55. Class 80(2). In a change-speed gear in which change of ratio is produced by the engagement of fluidpressure operated friction clutches, the lower speed clutch is partially engaged to cause slip of the engaged higher speed clutch until approximate synchronization of the lower speed clutch is achieved, then the lower speed clutch is fully engaged and the higher speed clutch disengaged. In a two-speed gear, Fig. 1, clutch K2 is engaged for direct or high ratio drive. The change to low ratio is effected by the partial engagement of the clutch K1 which causes slipping of the clutch K2 until the shafts b, c are approximately at equal speeds, then the clutch K1 is fully engaged and the clutch K2 released. In high ratio a pump 10, driven from the engine, supplies fluid to a main 12 leading to ports in a primary valve U, a control valve S3, two gear change valves W, S1 for the clutches K2, K1 respectively and a cut-off valve S2. The previous fluid is led to a space 22 in valve U which in conjunction with a spring 26 and pressure from a pump 32a on the output shaft hold the valve U in its full downwards position. This allows pressure to be transmitted to a space 39 in valve W and through space 40 to the clutch K2. A pipe 60 from the supply to K2 together with a spring 54 holds the valve S1 in the position to shut the port 59 to clutch K1 from pressure fluid. In this condition the clutch port 59, the space 41 and the accumulator R are vented through the throttling valve 45 and pipe 44. To engage the lower gear, further opening of the throttle 29a moves the valve S3 to pass pressure to the space 21 and move the valve U to its upward position, which allows the space 39 to be vented and pressure to pass through the valve 45, which acts as a throttling valve in this flow direction but provides a fuller flow in the reverse direction, to port 59, space 41 and the accumulator R. The pressure in pipes 47, 46 builds -up in accordance with the characteristics of the valve 45 and accumulator R until full pump pressure is attained. Under these conditions clutch K2 is still under full pressure and clutch K1 engages under partial pressure until the accumulator R is charged. When full pressure is obtained in pipe 46 the differential pressures and the spring 38 move valve W to vent the port 43 of clutch K2 and space 57 of valve S1 which moves under the action of pressure in chamber 55 to open port 59 of clutch K1 to pressure from pipe 61. This results in full disengagement of clutch K2 and full engagement of clutch K1.

Abstract: 1324521 Rotary dryers INTERNATIONAL PAPER CO 4 Aug 1970 [4 Aug 1969] 37569/70 Heading F4G In a Yankee dryer 10, the efficiency of removal of condensate from the shell 12 is enhanced by accelerating the steam along the surface of the condensate as the steam approaches exit orifices 52 disposed adjacent the inner surface 60 of the shell 12 and leading to exhaust manifolds 34 rotating with the shell 12, so that the steam shears condensate from the surface 60 and entrains the condensate. In an embodiment, Figs. 3 and 5, the orifices 52 are formed in a plate 50 which is secured to each exhaust manifold 34 and defines with inner surface 60 flow channels 56 each of which decreases in cross-sectional area towards the orifices 52. The total cross-sectional area of outlet tubes 64 is less than that of the inlet tubes 62 leading from the orifices 52, so as to accelerate the steam further. The manifolds 34 exhaust via outlet pipes 40 to a passageway 42 which passes through the steam inlet 28 and is coupled by a rotatable coupling 26 to an exhaust conduit 44. In another embodiment, Figs. 6 and 7 (not shown), the flow channels 56 are of constant cross-section and extend from one side of the plate 50 only, but the steam is accelerated by passing between the first part of the plate 50 and the surface 60. The outlet tubes 64 are dispensed with, the outlet pipes 40 being connected directly to the ends of each manifold 34.
