Title: Suction holding-appliances for handling loads
IPC: B66C1/02
Filed: 1950-12-28
Abstract: 691,561. Suction appliances for handling loads. BILLNER, K. P. Dec. 28, 1950. [Feb. 1, 1950] No. 31467/50. Class 78 (iv). Valves 36 (Fig. 4) controlling the suction connections of a plurality of flexibly connected hollow sucker mats 12 for gripping a load are each opened when a corresponding feeler 38 projecting beyond the face of the work-engaging gasket 22 of the mat engages the work. Each of the three mats 12 shown in bottom plan in Fig. 2 is formed with a suction chamber 14 defined by deformable gaskets 16 (Fig. 4) adhesively secured between locating strips 18 and 20 to a common flexible lifting frame 10 and is provided with a limp sealing flap 22 for engaging the work. Each valve 36 is carried on a lever 32 pivoted between brackets 30 on the frame 10 and projecting at 38 beyond the face of the flap 22 ; thus as each lever 32 is brought into contact with the surface of the work the corresponding chamber 14 is exhausted. In one alternative construction the mats 12 are disposed radially on the frame, which is shaped for engagement with a curved surface, and are formed as trapeziums with radial sides separated by radial slots cut in the frame 10 between adjacent mats. In a construction for engaging the sides of a submarine vessel square mats are disposed in rows and columns on a vertical rectangular frame which is formed between each column with a tapering slot extending from the bottom of the frame to within a short distance from the top. In all these constructions the suction connections to the mats preferably include flexible portions permitting relative movement of the mats. The pivots of the levers 32 are preferably nearer to the valves than to the workengaging ends so that the valves are not opened fully until sealing is complete, and the valves may normally be biased towards their seats by the pressure difference across them.

Abstract: 536,036. Photographic copying-apparatus. HALL, J. V. Dec. 6, 1939, No. 31626. Convention date, Jan. 5. [Class 98 (i)] A photographic copying apparatus comprises a lens with means to support it in relation to the object to be copied, masking means of adjustable area in alignment with the lens, and a film carrier movably mounted on the masking means so that it may be moved over the opening in the mask to expose the film, or away from it to allow of focusing and adjustment of the opening in the mask. The apparatus shown comprises a base 10 with a recess 11 in which the matter to be copied is inserted and pressed against a transparent cover plate 13, the base carrying a pair of pillars 15 on which a crosshead 16 carrying the camera apparatus 18, is vertically adjustable. The apparatus 18 includes a housing 21 for the objective and a housing 19 for a lamp 20 used for adjusting and focusing purposes. In the space between the housings 19, 21 is an adjustable masking device shown in Fig. 4 with its cover plate removed. This comprises two pairs of slides 32, 33 adapted to be adjusted in slideways 31 so as to mask off a portion of the width or length of the exposure opening 40 in accordance with the proportions of the matter to be copied. The slides are operated by a rotary disc 28 with an operating lever 29, pins 34, 36 on the slides engaging cam grooves in the disc of such form that movement of the lever to the right of its central position moves the slides 33 inwardly to reduce the length of the opening, whilst movement to the left moves the slides 32 to reduce the width. During this adjustment, the film carrier 44 extending between the film spool compartments 47 is moved forwardly against stops 50, so that a frame 54 secured to it and carrying a transparency with a focusing spot 53 in the horizontal plane of the film coincides with the opening 40. Illumination of the lamp 20 causes the mask opening and the focusing spot to be projected on to the copy, so that the necessary masking and focusing adjustments may be made. The film carrier is then moved backwardly against stops 51, when an exposure window on its underside registers with the mask opening 40.

Patent GB-821563-A (GB)
Title: Improved diaphragm-operated master pulsator for milking machines
IPC: A01J5/12
Filed: 1956-10-22
Abstract: 821,563. Pulsators. SEABORNE, T. L. Oct. 22, 1956, No. 32109/56. Class 84. A master pulsator for a milking installation comprises an unbalanced diaphragm system operating a valve system which produces the pulsations, the pulsations controlling the diaphragm system. The vacuum is applied through a conduit 17 into a passage 18 and chamber 19. Atmospheric pressure is established in chamber 26 through passage 25 and air intake 20. Meanwhile air from chamber 30 is bleeding through a nozzle 34 into the vacuum line. The force on the lower diaphragm is thus downward and that on the larger, upper diaphragm 4 is initially downward also. However as the pressure in chamber 30 falls, the force on the diaphragm 4 gradually reverses till it overcomes the downward force on the lower diaphragm 5 and the coupled unit moves upward taking the valve 10 with it. Vacuum is now applied at 26 and air at 19. The forces on the combined diaphragm assembly gradually reverse as atmospheric air bleeds back into 30 and the diaphragms thus reverse. The alternations of pressure in chamber 19 are conducted to the relay pulsators coupled to line 29. Glass beads are added to the chamber 30 on a grid 31 to vary its volumetric capacity and thus the rate of pulsation which can be further modified by changing nozzle 34.
Patent GB-917648-A (GB)
Title: Pressure-medium controlled liquid valve
IPC: F16K31/122
Filed: 1960-09-20
Abstract: 917,648. Valves. HARTUNG, W. Sept. 20, 1960 [Sept. 21, 1959], No. 32244/60. Class 135. A main valve controlled by auxiliary valves which are under the control of a meter whereby a preselected quantity of fluid can be discharged is provided with pressure-responsive elements that allow closure of the main valve in two stages to prevent shocks in the fluid conduits. As shown, a main valve 3 is held open, against the loading of a spring 27 and the net upward force of pressure from a conduit 11 acting in a chamber 9 on a diaphragm 4 and a piston 7, by pressure admitted through an adjustable throttle 26 and an auxiliary valve 14 to a chamber 12 above the piston 7. When a predetermined portion of the preselected quantity of fluid has been passed by the main valve an electromagnet 25 under the control of the meter operates the auxiliary valve 14 to vent the chamber 12 through an adjustable throttle 29, whereupon the main valve will close to an extent determined by a stop 19 which carries an adjustable nut 21 and is urged downwardly by pressure in a chamber 18 above a piston 16. When the main valve has delivered the complete quantity of fluid an auxiliary valve 23 is actuated by an electromagnet 25 under the control of the meter to vent the chamber 18 and allow the main valve to close. The auxiliary valves 14, 23 may be operated mechanically instead of by electromagnets. The pressure chamber 9 may be dispensed with, or the supply of pressure fluid to it may be controlled by a further auxiliary valve which provides for venting during the opening movement of the main valve. In a modification, the stop 19, piston 16 and auxiliary valve 23 are omitted. In this case the main valve is fully open when the chamber 12 is pressurized and the chamber 9 vented, takes up its intermediate position when the chamber 9 is pressurized, and closes when the chamber 12 is vented.

Abstract: 740,300. Making electrodes for electroerosion. DEUTSCHE EDELSTAHLWERKE AKT.-GES. Nov. 20, 1953 [Nov. 22, 1952], No. 32329/53. Classes 83 (2) and 83 (4). Powder metallurgy.-An electrode for use in removing metal by electro-erosion is produced by pressing together metallic particles and then sintering if necessary. The particles may be of metal or alloy and may comprise chips. There may be added a binder, about 30 per cent of aluminium oxide which is consumed less rapidly than the metal and also a thermosetting resin or alternatively stearic acid or petroleum jelly. If a porous electrode is required there is added to the mixture a material such as a low melting-point alloy or sawdust which is melted out or burnt out during the sintering operation. Such an electrode may be impregnated with substances intended to influence the sparking. Similarly continuous cavities could be formed in the electrode by means of a lead wire or wooden rod embedded during moulding. In an example copper powder that will pass 100 mesh sieve is mixed with 30 per cent by weight of aluminium oxide powder and, if desired, with 5 per cent of a binder, the mixture pressed around a pattern or into a die at 425 lbs. per sq. inch and sintered at 900‹ C. If a porous electrode is required 5 per cent by weight of sawdust is also added to the mixture.
