IPC: B08B9/08
Filed: 1957-04-10
Abstract: 800,337. Cleaning barrels. WILD, H. VON, and RICHARDT, H. [trading as NEUBECKER C. A. [Firm of]]. April 10, 1957 [April 11, 1956], No. 11690/57. Class 138(1). An automatic barrel washing machine comprises a conveyer which transfers the barrels from one washing station to the next, the weight of a deposited barrel operating valve control members, for the internal cleaning of the barrels, to connect a control shaft, connected to the conveyer mechanism and arranged along one or both sides of the machine, to levers for operating the valves. The conveyer 1 moves through a rectangular path, the movement being effected by a motor-driven cam 2 acting on levers 3, 3a, lever 3 producing the vertical movement of the conveyer through four bellcrank levers 5 and connecting rods 4, 4a, and lever 3a producing the horizontal motion by means of driving members 8, cranks 6 and connecting rods 7. An oscillatory motion is imparted to the control shafts 11 by the rear bell-crank levers 5, rods 9 and levers 10 which terminate with toothed segments 10a meshing with a bevel wheel 11a keyed to the control shaft 11. The machine is provided with six internal cleaning stations the six valves 25, three on each side of the machine, each controlling nozzles 18 which are inserted into the bunghole to spray liquid against the inside surface of the barrel. On reception, the barrel is rotated on rollers 16, Fig. 6, and the outside is cleaned by the brushes 13 being moved downwards by the yoke and rollers 29 through levers 12a fixed to the control shafts 11 and by the brushes 14 which are moved into contact with the ends of the barrel by levers 12b and 30. The barrel is then orientated with the bung-hole at the lowest point by rollers 17 and a hook 15 which prevents further rotation of the barrel. The introduction of the cleaning liquid by the nozzles 18 is controlled by a lever 19, Fig. 4, being depressed by a barrel to operate Bowden cables 21 thereby moving bell-crank levers 22 pivoted at 22a interposing the bolts 20 between the plunger 28, which is oscillated continuously in a vertical direction by the shaft 11, and the top of the valve 25 which is opened by the plunger 28 to admit a spray of liquid into the barrel. When the barrel is removed, the bolts 20 move apart and the plunger 28 operates in free space.

Title: Improvements in or relating to control valve systems for fluid-pressure operated piston and cylinder machines
IPC: B30B15/16
Filed: 1954-04-28
Abstract: 787,989. Engine valve-gear. FLYNN, D. H. July 8, 1955 [April 28, 1954], No. 12272/54. Class 122 (2). [Also in Group XXIX] A control valve system for fluid-pressure operated piston and cylinder machines comprises inlet and exhaust valves 17, 17<SP>1</SP> and 16, 16<SP>1</SP> actuated by pressure fluid controlled by a shuttle valve 12 itself operated by pressure fluid controlled by a pair of pilot valves 5, 51. In the arrangement shown in Fig. 1 for a doubleacting steam engine 22, valve actuating fluid supplied at 4 passes through bores 6, 6<SP>1</SP> in the stems 7, 7<SP>1</SP> of pilot valves 5, 5<SP>1</SP> to passages 10, 101 leading to chambers 11, 11<SP>1</SP> at the ends of the shuttle valve 12. Tappet operated valves 8, 81 extending through exhaust openings 9, 91 control the bores 6, 6<SP>1</SP>. Passages 13, 13<SP>1</SP> connect chambers 11, 11<SP>1</SP> with the pistons 14, 141 and 15, 151 of the inlet and exhaust valves respectively, the exhaust valves being interconnected by a stem 23 and communicating with a steam exhaust port 24. Steam is supplied to the inlet valves 17, 171 through a port 19. In the position shown, the inlet valve 17 is opened and the exhaust valve 16 closed by the pressure of fluid in passage 13 and steam is supplied to the top of the engine cylinder via port 19, inlet valve 17, passage 20 and port 21 and exhausted from the bottom through port 21<SP>1</SP>, passage 201, exhaust valve 16<SP>1</SP> and port 24. The engine piston moves downwardly until the valve 8 is tappet operated by suitable means, such as a cam or solenoid, to first seal off the bore 6 and then operate the valve 5 to connect chamber 11 to exhaust opening 9. The pressure beneath shuttle valve 12 then moves it upwardly and passage 13<SP>1</SP> is pressurized so that valve 17<SP>1</SP> is opened and valve 16<SP>1</SP> closed; the valve 17 being closed by the steam pressure. The steam and exhaust connections to the engine cylinder are thereby reversed and the piston moves upwardly until the valve 81 is tappet operated to return the shuttle valve 12 to its original position and the cycle recommences. The valves 8, 81 are operated only momentarily at each end of the piston stroke. To facilitate starting the cross-sectional area of piston 151 is made appreciably greater than that of piston 15. In a modification for a single-acting steam engine the inlet valve 17<SP>1</SP> is omitted. The working fluid may also be used as the valve actuating fluid.

Class 73 [Also in Group XVI] Relates to a labelling-machine in which a rotatable delivery member 16, Fig. 1, is formed with suction openings at spaced positions round its outer face and is adapted by suction to extract a label from a reciprocating stack 19 and carry it to the labelling station. The delivery member 16 has interior compartments shown in positions 1-6 in Fig. 1 in communication with the suction openings, a suction passage 30, Fig. 2, leading into each compartment and a rotary plate valve 21 comprising an upper member 22 rotating with the member 16 with ports 29 connected to the suction passages 30 and a lower stationary member 23 having one port 28 which communicates with one port 29 of the rotary member 22 when a compartment associated with that port 29 is in position 1, Fig. 1, adjacent the label stack 19, the stationary member 23 also having an arcuate port 32 registering simultaneously with the ports 29 of the compartments when in positions 2-5, separate suction connection's from separate vacuum pumps to the two ports 28, 32 being provided. The arrangement is such that each compartment when in position 1 opposite the label stack is subjected to a high degree of suction to extract the label and then when the delivery member is moved through positions 2-5 to the labelling station a lower degree of suction is applied through the arcuate port 32 sufficient to retain the label until removed by adhesive contact with the article. No suction is provided at position 6. The delivery member may be cylindrical, e.g. if the member itself is used to produce or assist a rolling of a cylindrical article over the label or as shown, multi-faced, e.g. if the article is to be pressed against or rolled over the label, and driven intermittently to bring faces to rest at the label stack and labelling station. Cylindrical articles 11, such as bottles, as fed upright on a conveyer 12, a driving band 14 at the labelling station rotating each article over a label on the delivery member 16. Where thermoplastic labels are used, a heating element 20 is located opposite compartment position 3 and a heated stream of air is directed to the label, or alternatively with ordinary gummed labels, adhesive may be applied at position 3 in which case the high degree of suction may be retained up to and including this position.

A red colouring matter, such as cadmium selenide, and 0.5-2 per cent of a pigment such as lithopone, titanium oxide, zinc sulphide, or zinc oxide may also be present.  The admixture is preferably obtained by adding the other ingredients to a 30-60 per cent solution of the polymerized styrol in a solvent such as ethyl benzol, which is subsequently driven off.  The material is powdered and used as such, or cast into blanks at 120-160 DEG  C. under a pressure of 300-500 lbs. per sq. in.  A composition giving a mottled effect is obtained by producing two batches, one having more red colouring matter than the other, and mixing the two in powdered form prior to moulding. The less coloured may be rendered opaque rather than translucent.ALSO:A denture is formed by moulding an admixture of previously polymerized tough styrol, obtained, for instance, by the methods disclosed in Specifications 236,891 and 243,768, [both in Class 2 (iii), Dyes &c.], or any suitable polymer of styrol homologues with siliceous material, such as that known under the Registered Trade Mark "Asbestine," or aglaite, diatomaceous earth such as celite, or talc, a maximum of 15 per cent being specified. The mixture preferably also contains a red colouring matter, for example, cadmium selenide, and 0,5-2 per cent of a filler such as lithopone, titanium oxide, zinc sulphide, or zinc oxide.  The admixture is preferably obtained by adding the other ingredients to a 30-60 per cent solution of the polymerized styrol in a solvent such as ethyl benzol which is subsequently driven off. The material is powdered and converted into blanks at 120-160 DEG  C. under a pressure of 300-500 lbs. per sq. in.  A composition giving a natural mottled appearance is obtained by producing two batches, one having more red colouring-matter than the other, and mixing the two in powdered form prior to moulding.  The less coloured may be rendered opaque rather than translucent.  In preparing the denture, a wax model complete with porcelain teeth is set up in a two-part plaster of Paris mould.  The sections are backed with metal, the wax melted out, and the cavity filled with the admixture in the form of powder or blanks, sufficient being used to form a small amount of flash. The denture is moulded at from 300-350 DEG  F. under a pressure of 400-800 lbs., cooled slowly and finally in water.  When cold, the denture is finished in the usual manner.
