Title: Improvements in or relating to safety non-return devices for use with acetylene generators
IPC: A62C4/02
Filed: 1931-06-24
Abstract: 375,998. Safety non-return valves. HERBST, W. J., Ballinhaus, Hamburg, Germany. June 24, 1931, No. 18280. [Class 135.] A safety non-return device for use with acetylene generators comprises a casing a divided into two chambers c, d by a diaphragm b carrying a hollow valve member f operating in both chambers. In the event, of an abnormal rise of. pressure in the outlet h the diaphragm moves against the action of a spring k to press the member against a seat on the acetylene inlet e and at the same time open a vent aperture i. The aperture i is made of small dimensions say 1 mm. diameter, to retard the discharge of pressure and permit a powerful action on the diaphragm. A ball non-return valve g is housed in the hollow member f. The diaphragm may be of metal or covered with metal to protect it from back-firing.

Title: Improvements in or relating to chucks for automatic lathes or like machines
Inventor: TOMLINSON GEOFFREY ERNEST SECK
IPC: B23B31/175
Filed: 1951-08-02
Abstract: 706,572. Chucks. B.S.A. TOOLS, Ltd. Nov. 3, 1952 [Aug. 2, 1951], No. 18295/51. Class 83 (3) The thrust tube 13 of a hollow-spindle chuck for gripping work of slightly-varying diameters is operated by means comprising one or more pairs of levers 43, 51, an outer sleeve 15 moved axially by a yoke 21 under the control of a cam track 25, and an inner sleeve 29 acted on by spring-loaded plungers 33. On initial rearward movement of the outer sleeve, the inner sleeve follows it under the action of the plungers 33 and a cone surface 44 rocks the levers 43 so that, through a thrust sleeve 45, thrust pads 47, 61, a fulcrum ring 49 and an adjuster sleeve 59, the thrust tube 13 is moved forward to close the chuck on the work. Continued movement of the outer sleeve leaves the inner sleeve behind, in the position according to the diameter of the work in which it has stopped, and a cam face 71 on the outer sleeve depresses the levers 51 so that, through an adjustable ring 57 and the members 59, 61, a positive pressure is applied to the tube 13 to close the chuck firmly on the work and, as the levers 51 pass into a parallel portion of the sleeve, to lock it in this position. The reaction of the levers 51 on the ring 57 is taken back, through the abutting members, to the cone surface 44 but, as the angle of taper is small, no return movement is possible against the spring-loaded plungers 33. The amount of gripping :pressure given by the levers 51 can be varied by axial adjustment of the ring 57 and, when so adjusted, will remain constant for all work-pieces within diameter limits of plus or minus 1 mm. The thrust tube 13 abuts a coned sleeve 9 which has return springs 63 and operates either a collet 3 or, through spring-loaded levers 7, radially-movable jaws 5.

Abstract: 507,871. Coin-freed game apparatus. SCHOTTE, H. June 22, 1938, No. 18604. [Class 27] [Also in Group XV] A coin-freed game apparatus comprises a table sloping in all directions downwards from the centre towards the sides, a series of holes 7 in front of each side communicating with a central ball-lifting device, and cues 6 projecting through slots in the sides of the table. Rubber cushions 12 surround the playing area. In playing a game, the competing players endeavour to drive the ball with the cues into the holes in front of their opponents. After passing through a hole the ball runs to the ball-lifting device 5 consisting of a cup pressed upward by a spring. By manually depressing the ball-lifting device, the ball enters the cup and on releasing the pressure is raised again 'to the playing surface for replay. Coin-action, mechanical-connection.-The balllifting device is locked to prevent recovery of the ball for play, by a locking bar withdrawn for play by the operation of coin-freed mechanism which at the same time sets clockwork mechanism in operation so as to return the locking bar after the lapse of a predetermined time. After inserting a coin into a slot 29, Fig. 6, to make an operative connection between a manuallyoperated bar 16 and a rack 31, the bar 16 is pulled out thereby drawing back the rack 31 which similarly (by interconnecting lugs) draws back the locking bar 25 into engagement with a catch 34. The rack at the same time winds up the clockwork mechanism 33. On releasing the operating rod the coin falls into the cash till and the clockwork mechanism unwinds and slowly returns the rack until at the end of the predetermined time the rack displaces the catch 34 and a spring returns the locking bar 25 to its locking position. The ball-lifting device may be locked by the locking bar in either its upper or lower position.

Filed: 1975-05-05
Abstract: 1499409 Colour television receivers INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 5 May 1975 [8 May 1974] 18813/75 Heading H4F A circuit for separating the colour difference signals in a received PAL or ISA chroma signal includes means for forming the sum and difference between a first signal, which has colour difference components having the same phase relationships as the colour difference components of the chroma signal but a reference burst at 90 degrees to the burst in the chroma signal, and a second signal which is the chroma signal delayed relative to the first signal by n lines (n odd). The ISA signal is similar to the PAL signal but the burst occurs in alternate lines only and is of fixed phase. As illustrated the delay 12 receives the chroma signal C via an inverter 11 and delivers the signal in true and inverted form to a coil 13 connected across its output terminals. The coil has a centre tap to which is applied the received chroma signal which has had its burst shifted by + 90 degrees, this signal being derived by way of gates 15, 18, controlled by line frequency pulses H. The colour difference components B-Y and Œ(R-Y) appear at B and ŒR respectively. The signal on the output ŒR passes to gate 22, controlled by pulses H to pass only the reference burst to a crystal sub-carrier generator 24 which provides a reference subcarrier REF.R and, via 90 degree phase shifter, a sub-carrier REF.B. When a PAL signal is being received phase shifter 23 introduces a + 45 degree shift to the bursts passed by gate 22.
