Title: Improvements in or relating to waggon tipplers
IPC: B65G67/00
Filed: 1934-02-12
Abstract: 418,101. Wagon-tipping apparatus. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd.., and KAY, I., Victoria Station House, Victoria Street, London. Feb. 12, 1934, No. 4583. [Class 78 (iv).] Means for raising and tipping a wagoncarrying cradle 5, 6 comprises an elevated rotatable structure 19 which on initial rotation raises the cradle, and on further rotation engages the cradle so that the cradle turns bodily with the structure. As shown, the cradle 5, 6 carries a pivoted rail-platform 1 and a side support 30 for the wagon, and is provided with rollers 8, 9 moving in or on vertical channel guides 7. The elevated structure is pivoted at 10 and is operated by winding gear 21. The structure 19 comprises three arms 11, 12, 13. The arm 11 is connected with the cradle by a link 14, so that rotation of the structure 19 through about 180‹ brings the rollers 8 on the cradle to the top of the guides 7. The same movement brings the arm 12 into the path of the rollers 8 so that the shaft 16 of the rollers 8 engages in the hook-shaped end 15 of this arm. The third arm 13 engages with an abutment 18 on the cradle so that on further movement of the structure 19 the wagon is turned with the cradle about the axis 10, the rollers 8 leaving the guides 7. A top clamping-bar 22 for the wagon is carried on arms 23 pivoted on the cradle at 24 and connected by links 25 to levers 26 pivoted on or near the axis 10, and weighted at 17. During the movement of the structure 19 for raising the cradle the weights 27 bear against stops 29 on the structure 19 and assist in raising the cradle, and during the later part of the movement for tipping the cradle the weights pass beyond their lowest position and hold the wagon against the rails. The structure 19 may be operated by toothed gearing.

Title: Improvements in electrostatic printing
IPC: B41M1/12
Filed: 1964-02-04
Abstract: 1,024,682. Electrostatic printing apparatus. ELECTROSTATIC PRINTING CORPORATION OF AMERICA. Feb. 4, 1964 [Feb. 11, 1963], No. 4644/64. Heading B6C. In an electrostatic printing apparatus a mixture of pigment particles and conductive carrier particles are placed in a container 20 having a non-conductive bottom forming a screen stencil 22 and incorporating contacts 24. The pigment particles are of such a size that they may pass through the apertures, of the stencil whilst the carrier particles are prevented, through their size, from leaving the container. The container is placed above a conductive member 26 on which printing is to occur. A potential is applied to electrodes 30, 32 and the member 26 whilst the container is mounted to reciprocate vertically such movement deriving from electrical or mechanical means. Instead of printing directly upon the member 26 a copy sheet may be placed thereon. In operation the container moves downwardly until the contacts 24 connect with the electrodes 30, 32 whereupon an electric field is created between the stencil 22 and the member 26 such that pigment particles are forced through the apertures of the stencil to impinge upon the member 26 or a copy sheet thereabove. Vertical withdrawal of the container allows the removal of the printed matter and the substitution of fresh copy. In the modification shown in Fig. 3 the potential is applied between the interior of the container and the member 26, suitable electrodes 40 being arranged within the container. In a further embodiment the container is fixed, the screen stencil 54, Fig. 5, being uppermost. The carrier and pigment particles are drawn upwardly to the stencil through the application of a magnetic field arising from the step-by-step actuation of an elongated electromagnet 68. As the particles reach the stencil underface they complete an electrical circuit thereby creating an electric field between the container and a plate electrode 52. This field forces the pigment particles through the apertures of the screen on to a copy sheet placed thereabove.

Title: Valve mechanisms
IPC: F16K31/18
Filed: 1963-02-06
Abstract: 1,033,656. Springs; valves. LIQUID CONTROLS CORPORATION. Feb. 6, 1963 [May 4, 1962; Dec. 5, 1962], No. 4870/63. Headings F2S and F2V. A spring arrangement for an actuating shaft is applied to a float-actuated valve, the casing 20 of which is secured around an opening in a tank 23, and is formed with lateral chambers 47a, 47b that open into the casing via orifices 46a, 46b, respectively. The chambers, which may be isolated or in communication, each have an outlet 42a, 42b, one of which, as shown, may be plugged. Flow through the or each of the orifices 46a, 46b, is controlled by spring-steel strip 51a, 51b, having one end attached to the casing 20 and the other to a wedged-shaped tubular stop 70 fixed to the float 72, the stop defining the upper position of the float. The stop and float are slidable over a stem 74 but the strips 51a, 51b centralize the former so that they do not bear on the stem 74. In operation as an air eliminator, the float is raised to the dotted-line position when liquid fills the tank and stands in the casing at the required level, the strips then closing the orifices 61a, 61b. Should air or other gas enter the casing 20 from the tank, the liquid level and hence the float 72 falls and the strips 51a, 51b are progressively " peeled from the associated orifices whereby the air escapes through one or both of the outlets 42a, 42b. The apparatus may be used as means of segregating a gas and a fluid or two liquids of different densities, in which application the valves and float are secured in the bottom of the tank; the valves close when all the heavier liquid has been withdrawn since the float is only buoyant in the denser medium. To prevent foreign matter being drawn in between the spring strips and the orifices the stop 70 is made cylindrical and the orifices and coacting parts of the strips are curved so that the opening and closing of the orifices is first delayed and then proceeds rapidly in the manner of an overcentre toggle. The characteristics of the valves may be varied by providing stops of various configuration so effecting the action of the spring strips. Alternatively, the stop may be cylindrical and the walls around the orifices variously shaped. The strips may have various shapes and sections or a series of holes of the same or different sizes therethrough. The valves may be actuated by means other than floats and any number of spring strips may be used to control fluid flow. Some or all of the strips may be used simply as loading means e.g. for another float-actuated valve, not shown, and co-operate with imperforate walls to resist or aid the motion of the actuator depending upon the configuration of the walls and stops.

Abstract: 980,945. Machine tool details. RHEINMETALL G.m.b.H. Feb. 9, 1961 [Feb. 13, 1960], No. 4923/61. Heading B3B. An indexing table assembly includes a wedge 13 for clamping the table downwardly against the pressure of a spring 20. The wedge consists of an annular split ring which is compressed by a pin 16 moved axially by an eccentric 17 rotated by a handle 19. Movement of the handle in the opposite direction rotates the table through gearing 22, 23 and a one-way ratchet drive 24. Rotating with the table is a series of index plates 25 with one of which a plunger 33 is engaged by adjusting a slide 27 vertically by rack-and-pinion gearing actuated by a graduated hand-knob 32. When the table is unlocked, a projection 36 releases the plunger from a recess by means of a pawl 34. Further movement of the handle moves the pawl against a releasing pin 37 causing the plunger to be free to enter the next recess. Lost motion of the handle 19 is permitted relatively to the table by a spring drive 40 and a pin 39. The handle 19 may be pneumatically or hydraulically activated.

Abstract: 1280973 Vacuum deposition BALZERS PATENT-UND BETEILIGUNGS A G 2 Feb 1970 [6 Feb 1969] 4976/70 Heading C7F Vacuum-deposition apparatus comprises a vapour source 4, thermal radiation from 4 being separated owing to its high speed of propagation from the vapour beam by means of a rotary baffle system comprising a plurality of vapour passage channels 12 which are rigidly connected to each other and arranged around a common axis like the generatrices of a cylinder, and said axis is inclined relative to the direction of the vapour beam at such an angle α that the source-to-article optical path through the vapour passage channels is blocked, and driving means are used to rotate channels 12 about said axis. Thus, whilst thermal radiation is prevented from striking substrate 3, rotation of the baffle assembly 8 at an appropriate rate allows vapour from 4 to pass unimpeded to substrate 3. The vapour passage channels may be provided by milling a cylinder, attaching radial laminae inside or outside a hollow cylinder, or by boring channels through a cylinder.

Title: Improvements in Carbureters for Internal-combustion Engines.
Inventor: PAYTON ARTHUR LEROY
IPC: F02M37/02
Filed: 1916-04-05
Abstract: 100,273. Payton, A. L. April 14, 1915, [Convention date]. Vacuum apparatus.-Fuel is supplied to the float chamber of a carburettor from a tank at a lower level by maintaining in the float chamber a substantially constant reduction of pressure, this being effected by allowing the float chamber to communicate on the one hand through a restricted air passage or automatic valve with the mixing chamber, and on the other hand with the atmosphere, through an aperture controlled by an automatic valve. The carburettor comprises an air-inlet portion 35 with hand-actuated valve 45, and suction actuated valve 46, a mixing chamber 37 with a suction actuated auxiliary air valve 49, and a float chamber 56 containing an annular float 57, surrounding a choke tube 38, which is secured between the mixing and float chambers and surrounds a nozzle 39 which may be adjusted axially by a tool inserted through a passage 40. The fuel reservoir 31, which is open to the atmosphere at 64, communicates with the float chamber by a pipe 32, the inlet of fuel being controlled by the float valve 60. The inlet to the float chamber may be below the fuel level in which case a non- return valve is provided in the supply pipe. The constant reduction of pressure in the float chamber is obtained by the use of two adjustable spring loaded ball valves 66, 73, the former of which opens into the mixing chamber and the latter into the atmosphere. The valve 66 allows the suction in the mixing chamber to be transmitted to the float chamber, and the valve 73 opens and admits air when the suction becomes excessive. The valve 83 may be situated between the valve 66 and the mixing chamber, so as to prevent the formation in the float chamber of an ignitable mixture. In a further modification the two valves are in a common casing corresponding to the casing 65 and are loaded by a common spring, but the float chamber valve is opened before the atmospheric valve on account of its orifice being made larger. It is stated that 1 lb. pressure reduction in the float chamber is sufficient to raise the fuel through the distances met with in motor vehicles.
