Title: Improvements in sequence valves
IPC: F15B11/20
Filed: 1942-12-31
Abstract: 559,410. Valves. VINCO CORPORATION. Dec. 31, 1942, No. 18602. Convention date, Dec. 26, 1941. [Class 135] A three-way valve device for use in hydraulic circuits which are to be controlled according to a predetermined sequence of operation for example a hydraulic circuit operating a clamp on a machine having a hydraulic ram comprises a spool valve 4 normally held by a spring 8 against a resilient stop 10 to close the passage-way between two conduits, pressure in either of the conduits being effective to open the valve. In the system shown in Fig. 1, a pump 24 driven by a motor 25 is connected with a drain connection 29. Pipes 27, 28 lead from the valve 26 to two valves 1, 30 constructed according to the present invention and having pipes 18, 21 and 35, 36 leading to double-acting power-cylinders 31, 33. The three-way valves each comprise a two-landed piston of which the upper land has notches 20 and is adapted to control the connection between chambers 17, 19. The chamber 19 communicates with the conduit 21 while the chamber 17 communicates with the conduits 15, 18, the conduit 15 also being connected by a passage 16 with a chamber below the lower end of the valve. When the pipe 27 is under pressure, fluid passes through the conduit 15, chamber 17 and pipe 18 to the lower end of the cylinder 31. When the piston 32 reaches the end of its stroke pressure builds up beneath the valve to move it against the action of the spring 11 to connect the chambers 17, 19 and allow fluid to pass through the pipe 21 to the left-hand end of the cylinder 33. During both these movements fluid is exhausted from the other ends of both cylinders through the valve 30. A similar series of movements take place when the pipe 28 is under pressure. Specification 559,346 is referred to.

Abstract: 726,875. Removing leakage. WIIK, R. July 6, 1953 [July 14, 1952], No. 18665/53. Class 113 (1). [Also in Group XXIX] In an automatic valve for boats having an outwardly opening conical valve disc 4, the seat la of which is arranged in the boats' bottom, means are provided whereby the valve can be kept in open position while it closes automatically when water flows in through the valve opening. The cylindrical housing 1 has apertures 15 for the outward flow of water, two oppositely arranged slits housing catch levers 5 pivoted at 12 and pressed upwards by springs 8, and houses a piston 3 whose hollow stem 13 is attached to the valve disc 4 and has movable therein a small piston 19 with a rod 10 which carries discs 7a and 7b having a spring 6 between them. The lower disc 7b rests on a shoulder in the housing 1 and in the open position of the valve, as shown in Fig. 1, the upper disc 7a is held by hooks 17 on the catch levers 5. The valve may be closed manually by pulling the button 11 or automatically due to inwardly flowing water acting on the pistons 3 and 19, in either case the piston 3 moves up along projections 16 on the catch levers to force the latter outwards thereby releasing the hooks 17 out of engagement with the disc 7a so that the spring 6 urges rod 10 upwards. The valve is opened by pushing the button 11. The bore in the stem 13 and the piston 19 may be of square section so that the valve 4 may be rotated by the button 11 if the seating is fouled.

Title: Article handling and imprinting apparatus and method
Inventor: SCHUELER MARLIN ALIOS
IPC: B41M1/12
Filed: 1966-05-02
Abstract: 1,098,120. Printing process; electrostatic printing. UNIMARK CORPORATION May 2, 1966, No. 19309/66. Heading B6C. In a machine for marking articles, e.g. fruit, located in holders on a conveyer belt by electrostatic deposition of powdered ink through a stencil each moving article is contacted for a relatively short time by a printing head moving at the same rate. Each article is located in a holder 8 on a conveyer belt 11, Fig. 1, whilst each printing head forms the outer end of a telescopically constructed unit 32 carried above the conveyer 11 on an endless band arrangement. The drive to all the moving parts of the machine is by a single motor 42, movement of the printing units 32 deriving from a belt actuated structure 40, 36, 57 whilst actuation of the conveyer 11 is effected through the belt 40 and bevel gearing elements 47, 48, 49, 51 and 52. A clutch arrangement is disposed on the shift 34 such that the drive to the printing units may be isolated at will from the drive to the conveyer belt 11. This clutch is actuated whenever a handle 53, spanning parallel plates 25 which are pivoted about a shaft 20 to the machine and carry the endless band arrangement supporting the units 32, is manually moved in a vertical direction. The marking operation is stopped by downward movement of the handle which causes the paths of the units 32 and holders 8 to separate with simultaneous disengagement of the unit drive. Each article 130 is contacted for a time represented by the line 148 on Fig. 2, by a printing head, movement of each head being predetermined by a cam track 81 engaged by a roller 82 projecting from the telescopic body of the associated unit 32. Each unit has upper and lower cylindrical portions 84, 83, Fig. 8, spring-biased into an extended position and incorporates longitudinal rotary drive means whereby a mohair brush 123 is oscillated above a stencil 135 during the printing operation. A clutch is embodied in the drive means whereby the drive to the brush 123 may be isolated should no article be presented for printing. The drive means are actuated by a stationary rack 128, Fig. 2, fixed to inner side of one of the plates 25, which is engaged by a sprocket wheel 89 attached to the means when the article 130 moving on the conveyer 11 and the printing head are in operative contact. Should no article be present the spring biasing of the unit 32 extends the lower portion 83 thus actuating the clutch. Correct spacing of the stencil of each printing head from the article to be printed is ensured by foam rubber pads 132 depending from the lower surface of the head. The electrostatic field at the printing station is generated through the connection of a source of D.C. potential to a stationary conductor 13, which is contacted by conductors attached to the holders 8, and to the printing heads. The markings on the articles are fixed by a spray of a liquid fixing agent issuing from nozzles 153. These nozzles may be controlled through cam arrangements operated by the moving holders 8.

Abstract: 927,997. Fabrics composed of agglutinated threads. N. L. OLKEN. May 29, 1961 [May 31, 1960], No. 19329/61. Class 74 (2). Multistrand unwoven two-layer fabrics are made by winding an array of parallel strands into a tubular column of polygonal cross-section, wrapping around said column a second similar array of strands crossing the first at a predetermined angle, and securing the crossed strands together. As shown, strands 3<SP>1</SP> are drawn from spools 1 mounted on a rotating annular platform and are engaged frictionally by, and helically wound upon, four upwardly travelling belts 7 ... 7<SP>111</SP> to form the first tubular array, of square section. The strands 3<SP>1</SP> are coated with adhesive by rollers 27 associated with troughs 37 or may be otherwise rendered adhesive, e.g. applying heat or a solvent. The strands thereafter travel through a second annulus 2<SP>1</SP> rotating in the opposite sense to annulus 2 and carrying a second batttery of spools 1<SP>1</SP>. A second array of strands 3<SP>11</SP> is thus wound over the first, crossing the latter at a predetermined angle, preferably 90 degrees. The crossed strands are dried by heaters at II and pass through a third rotating ring C carrying two disc knives c which are set parallel to one array of strands and cut the tubular fabric into two flat sheets S. In a modification non- travelling disc knives slit the fabric across the strands which then have a diagonal formation in the flat sheets produced. The sheets are wound up on rollers 11 set at the angle of the cross-strands, the rollers being rotated by endless aprons bearing on the fabric being wound and passing around driven and idle rollers one on each side of each roller whereby the take-up of the rollers is maintained constant irrespective of the amount of fabric rolled on them. All parts of the apparatus are driven in synchronism by electric motors M, M<SP>1</SP>, M<SP>11</SP> and bevel gearing such as 15, 16, 19, 19<SP>1</SP>. Although four belt 7 ... 7<SP>111</SP> are shown three, or more than four, may be used. The strands may be of glass fibre or cotton. Specification 825,925 is referred to.
