Title: Improvements in multiple spindle automatic turret lathes
IPC: B23B31/30
Filed: 1935-09-17
Abstract: 445,240. Lathes; chucks. PITTLER WERKZEUGMASCHINENFABRIK - AKT.- GES., Wahren, Leipsic, Germany. Sept. 17, 1935, No. 25803. Convention date, Sept. 17, 1934. [Class 83 (iii)] In an automatic work-spindle turret lathe or like machine, the chucks on all the spindles are operated by fluid pressure cylinders which are controlled by a single centrally arranged valve adapted to connect each cylinder in turn to a hand controlled valve for opening and closing the chuck at a particular turret station, the central valve being indexable so as to vary the turret station at which a chuck may be opened. The central valve comprises a body 12, 16 attached by screws to a plate 12a rotating with the turret in a frame 15a. A disc 11 co-operating with ports in the body 12 is secured to a normally stationary shaft 10 indexable by means of a hand wheel 19 and spring plunger 22 within a bracket 26a attached to the frame 15a. Fluid pressure, preferably air, is supplied from the pipe 1 and the hand-controlled valve 3 to pipes 5, 6 attached to a stationary casing 7 and thence by annular chambers 7b, 7c to passages o, l in the shaft 10 and radial passages b, f in the disc 11. The body 12, 16 rotates with the turret so that on indexing of the latter, passages c<1>, g<1> in the body, connected by pipes d<1>, i<1> to opposite ends of each of the chuck cylinders 14a, are brought in turn opposite the passages b, f in the stationary disc 11 whereby the chuck at that particular station may be opened or closed by operation of the valve 3. A pipe 25, in constant communication with the pressure supply 1, leads to a passage k in the shaft 10 and thence to a space l in the body 16. This constant pressure assists a spring 24 to maintain the disc 11 against the casing 12 and also passes through a port m and a part-circumferential groove n to the passages g<3> and pipes i<3>, connected to the chuck cylinders which are not at the opening station, thereby maintaining these chucks closed and making up leakage. The opening passages and pipes c<3>, d<3> at these stations are closed at x by the face of the disc 11. In order to change the turret station at which a chuck may be opened, the disc 11 is rotated by the hand wheel 19 and is locked in the indexed position by the spring plunger 22. Each chuck is operated by a draw-spindle 27a carrying two pistons 17, 17a working in a double cylinder 14a attached to the work spindle 18a, the closing pressure being admitted to the cylinders by passages 31 and the opening pressure by passages 30. The passages 30, 31 lead from distributing casings 13a attached to the cylinders 14a and connected by the pipes d<1>, il, &c. to the casing 12. A pressure ga,uge 2b is in communication with the supply pipe 1, and a main supply cock 2 is provided.

Title: Improvements in or relating to mixing faucet
Inventor: ADAMS ARTHUR HAIG
IPC: F16K11/087
Filed: 1962-07-05
Abstract: 996,454. Valves. J. E. MEAGLER. July 5, 1962, No. 25838/62. Heading F2V. A mixing tap comprises a spherical closure member 40, Fig. 2, having inlet passages 66, 68, for controlling flow of hot and cold water from supply passages 24, 26 and an outlet passage 70. The ball is moved about two perpendicular axes by a rod 42, connected to a handle 44 having a spherical portion 48 co-operating with a cap 50 of the housing. The rod 42 passes through an opening 65, Fig. 3, the shape of which determines the registry of the inlets 66, 68 with the inlet passages 24, 26. The passages 24, 26 converge towards the valve seat at an angle less than that between the passages 66, 68 in the ball and these latter passages are smaller in diameter than the inlet flow passages. When the rod 42 is in the position shown in full lines, both inlet passages are closed and when in position 42o both inlets are fully open. In moving the rod from position 42h or 42c towards 42o, one inlet is gradually opened prior to reaching position 42o. The inlet passages are provided with spring-loaded sealing members 34 which are also subjected to the inlet pressure to maintain sealing contact with the ball. The upper portion of the ball is sealed by an annular ring 60, the clamping of which is adjustable by a ring 52. The outlet passage 70 registers with passages in the valve body which lead to an annular space 16 between the body and cylindrical member 10 carrying an outlet spout. The member 10 is rotatable through 360 degrees. In a modification, Fig. 9, a second outlet 100 is provided to which a hose 102 is connected, the end of the hose carrying a stop valve. A diverter valve 104 controls the flow to the outlet 14 or 100. This valve comprises a first valve closure 120 and a resilient non-return valve closure 128 of larger diameter than a port 118 such that fluid-pressure in the space between the closures would cause the valve member 120 to seat. When the ball is operated and fluid flows through the passage 72, the closure 128 is deformed to allow flow to the hose. If the valve and the end of the hose is open, the valve member 120 remains seated. If the valve at the end of the hose is closed, the back pressure reaches the pressure in passage 72, thus equalizing the forces on the closure 128 whereby the fluid pressure in the passage 72 opens the valve member 120 to allow flow to the outlet 14. A ball valve 130 having a seat 132 is provided between the passage 72 and annular space 16 to prevent back syphoning.

Title: Power supply protection arrangement
IPC: H04N3/185
Filed: 1964-06-23
Abstract: 1,040,872. Sawtooth circuits. RADIO CORPORATION OF AMERICA. June 23, 1964 [July 17, 1963], No. 25928/64. Heading H3P. [Also in Division H2] A protection arrangement for a colour television receiver in which the E.H.T. supply is derived from flyback pulses in the horizontal line output transformer 60, is arranged to limit the E.H.T. voltage in the event of failure of the normal E.H.T. voltage regulator triode 90 and comprises applying negative feedback to the horizontal line output pentode 50. Positive - going flyback pulses are fed from a tapping D or transformer 60 via a capacitive potentiometer 106, 108 to the grid 113 of a blanker triode 110 (used to prevent lighting-up of the flyback trace lines) causing grid current to flow and thereby giving the grid 113 a negative bias. The bias for the control grid 53 of the horizontal line output pentode 50 is derived from a potentiometer network 47, 48, 126 connected between a positive supply and the grid 113. In normal operation regulator triode 90, which derives its grid bias from transformer 60, maintains a constant loading of the rectified E.H.T. supply and so stabilizes the amplitude of the flyback pulses and hence the value of the grid bias on the triode 110 and pentode 50. Should the normal regulation fail the E.H.T. voltage will tend to rise, thereby driving grid 113, and hence grid 53, more negative so that the output of pentode 50 will decrease and thus reduce the E.H.T. voltage. In a modification (not shown), resistor 47 may be taken to earth instead of to the positive supply and the value of resistor 126 may be increased to maintain the correct bias on grid 53. In a further modification (not shown), a bias potential may be developed across a voltage dependent resistor instead of on the blanker triode grid 113.

Title: Relaxation oscillation generator
IPC: H03K6/02
Filed: 1933-09-20
Abstract: 425,686. Valve generating circuits. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Sept. 20, 1933, No. 25943. Convention date, Sept. 24, 1932. [Classes 40 (iii) and 40 (v)] Curvature in the charging-curve of a condenser 3 in a relaxation-oscillation generator is corrected subsequently. For this purpose the oscillations are amplified by a pentode 4 working on the bottom bend of its characteristic curve. This valve is coupled to the deflecting plate of a Braun tube 10 by a resistance 8 of 20,000 ohms. This resistance is between the individual members of the pair of deflecting plates and is so small that the error, due to current between the cathode ray and the plates, is negligible. The size of a television image produced by the tube is adjusted by varying the grid bias 6 of the amplifier, and the position of the image is adjusted by varying the potential 9 of the deflecting plate which is at a steady potential.

Abstract: 504,332. Step - by - step conveyers. POPOV, V. D. Sept. 6, 1938, No. 26075. Convention date, Sept. 6, 1937. [Class 78 (i)] [Also in Group XVIII] In a machine for weighing out doses of material or for sorting articles according to weight, partial doses or the articles are passed in two streams on to a table 4 which is reciprocated vertically by cam mechanism. As the table rises to its highest position, it is met by a vertically reciprocating rake 36 which is then given an horizontal movement to push the partial doses or the articles 26 along the opposite sides of the table. The partial doses or the articles are thus given a step-by-step movement to the positions I-I... VI-VI, and the weights are checked after descent of the table, by weigh beams A<1> ..A<4> at the positions II-II and IV-IV. At the next positions, material is added to the partial doses if required, or the article if of appropriate weight is discharged through a controlled gap in the table. At the last position VI-VI the gap in the table is permanently open.

Abstract: 190,285. White, J. Oct. 8, 1921. Pulping-engines. -- Means are provided for detecting and measuring the wear of the knives of the bed plate. From time to time the beater roll and bed plate are moved relatively towards each other to maintain the required intensity of contact, and this movement is used by connecting a moving member such as a bearing-block 3, Fig. 1, by adjustable mechanism to a pointer 2 traversing a scale 1. The movement of a rod resting on the shaft 12 of a beater roll, or of a rod connected to the roll-adjusting lever may be used. Instead of a pointer and scale, a bulb 17, Fig. 4, containing liquid may be connected to a gauge 18, the rise of the liquid in the gauge, produced by the pressure of an arm 16 in the bulb indicating the wear. Where the bed plate 21, Fig. 5, is raised, the movement of a stud 22 attached to the bed plate, may be communicated to a pointer on a scale by a lever 23 pivoted at 24, a flexible diaphragm 25 serving to prevent leakage of the stuff.
