Filed: 1918-07-19
Abstract: 121,094. Slack, H. F. July 19, 1918. Contents, delivering etc.; apparatus for fixing sieve-bags in boxes. In a box for toilet powder, the powder is contained in'a bag or sieve, which is made of fabric and is secured to the side wall of the box. The bag may wholly enclose the powder and may be secured directly to the side wall a, Fig. 1, by adhesive g, a sliding ring x being secured to the upper part of the fabric, so that it remains flat as the powder is used. In another arrangement in which the bag has an open bottom, the box is inverted to secure the bag in place, the bag d, Fig. 5, with the enclosed powder, being placed in a tubular device k surrounding a plunger j. A securing-ring k<2> coated with adhesive is placed inside or outside of the mouth of the bag, and the parts j, k are then moved relatively to the box so as to bring the ring k<2> into its required position at the bottom of the box. The ring k<2> may be replaced by a disk l, Fig. 8, or may be dispensed with, a coating of adhesive being applied directly to the bottom portion of the side wall of the box. An inner member b<1> of the box may be caused to act in a similar manner to the tubular part k, Fig. 5, the mouth of the bag being, in this case, secured between the member b<1> and the body of the box. In another arrangement, the bag is inserted in an empty condition through a hole in the bottom of the box, the hole being closed by a disk after the bag has been filled.

Title: Improvements in or relating to diaphragm pumps
IPC: F04B43/067
Filed: 1964-03-20
Abstract: 1,017,228. Reciprocating pumps. W. SEBARDT. March 20, 1964 [April 9, 1963], No. 11897/64. Heading F1A. In a diaphragm pump, e.g. for liquids containing solid particles, comprising a diaphragm 18 reciprocated by a piston 12 acting through a liquid column, the volume of the liquid column is maintained constant by bleeding-off a quantity of the liquid column through a flowrestricting valve 27 during the delivery stroke, and passing it via pipe 29 to the crankcase chamber behind piston 12, the bled-off liquid and the leakage liquid in the crankcase then being passed back to the liquid column during the suction stroke via a spillway 31 and a float valve chamber 32. The quantity bled off is made larger than that leaking past piston 12. Chamber 32 encloses a float-controlled valve and a check valve. The float valve prevents air from being drawn into the liquid column. A magnetically-actuated valve 28 closes bleed-off pipe 29 when the pump is stopped. The bled-off liquid serves to lubricate the bearings of connecting rod 13. Pump ball valves 24 are rubber covered. Piston 12 is actuated by an electric motor 16.

Patent GB-902686-A (GB)
Title: Mobile track-packing machine
IPC: E01B27/16
Filed: 1959-04-09
Abstract: 902,686. Railway track packing machines. PLASSER, F., and THEURER, J. April 9, 1959 [April 14, 1958], No. 12045/59. Class 104 (2). A mobile track-packing machine has a verticallyadjustable packing-tool carrier, which, after the machine is stopped above a sleeper, is lowered, and after the sleeper has been packed, is lifted before the machine moves on to the next sleeper, the sequence of these operations being automatically controlled by the arbitrary operation of a brake which acts on the running gear of the machine. The apparatus operates as follows:-When a key 30 is depressed the current supply to a switch 36, from an accumulator 32 through lines 33, 35, and to electromagnetic valves 22, 24, through lines 39, 40, 41, is interrupted so that air cylinders 8 and 4 are vented to atmosphere to disengage a clutch 7 and apply a brake 3 to stop the machine. At the same time a circuit through line 60 to magnets 561, 57<SP>11</SP> of electromagnetic valves 56, 57 is closed to allow a pressure medium to pass to the upper part and to vent the lower part of a cylinder 20, thus allowing the tool carrier 11 to be moved downwards. As soon as the carrier 11 is moved downwards an abutment thereon disengages a member 37 of the switch 36 to break the circuit to valves 22, 24, thus enabling the switch 30 to be released. When the carrier 11 descends its lower edge operates a rapid break switch 44, through an arm 45, to permit an electrical impulse to be given to a magnet 48<SP>11</SP> through line 47. The valve 48 now operates to allow a pressure medium to pass into chambers 17<SP>11</SP> of cylinders 17 to move packing-tools 15 towards one another to consolidate ballast beneath the sleepers. When the desired consolidation pressure is reached a pressure-sensitive switch 52 operated by the pressure in the valve 48 emits an impulse through a line 51 to a magnet 481 to cause the valve 48 to supply pressure medium to chamber 17<SP>1</SP> from a pump 50 to move the tools 15 apart. The switch 52, through lines 53, 54, 55, also transmits an impulse to magnets 56<SP>11</SP>, 57<SP>1</SP> to change over valves 56, 57 to raise the carrier 11. The abutment 38 on reaching the member 38 operates the switch 36 to close a circuit to the valves 22, 24 to enable the clutch 7 to be engaged and the brake 3 to be disengaged.

Patent GB-1337837-A (GB)
Title: Valves for fluids
IPC: F15B13/04
Filed: 1971-04-30
Abstract: 1337837 Control circuits for hydraulic apparatus SPERRY RAND CORP 30 April 1971 [4 May 1970] 12367/71 Heading F1P [Also in Division F2] A spool valve 10 having a pressure inlet 18, an outlet 20, and motor ports A, B is actuated by pressure fluid under the control of pilot means 50 and communicated to either end of the spool. Movement of the spool in either direction is resisted initially by a high rate spring formed by discs 112 and later by a low rate spring 130. The pressure inlet 18 communicates with the chamber at each end of the spool via a common line 26, and branches 32, 34 which contain fixed restrictions 36, 38 and have arms 40, 42 each containing a paralleled variable restrictor and check valve 44. Arms 46, 48 of the branches communicate with a four-way pilot valve 52, which acts to connect one of these arms directly to exhaust at 56 and the other to a variable-loading relief valve 54. The two valves 52, 54 are actuated by a common lever 76 which during the first part of its movement in either direction moves the valve 52 to open position via a spring-loaded link 78, shaft 82 and links 88, 90. Further movement of lever 76 causes the spring-loading to be compressed and an abutment 102 or 104 on a shaft 92 on which lever 76 pivots to contact an abutment 106 or 108 on a lever 96 to gradually increase the loading of valve 54. The result of these movements of the lever 76 is to vent one end chamber of spool valve 10 and to gradually increase the pressure in the other chamber to move the spool. The latter during its movement first compresses the high-rate spring disc stack 112 through piston 136 which is maintained in its outer position by inlet fluid pressure communicated to chamber 132 via check valve 140. When the spring 112 has been fully compressed further increase in pilot pressure causes fluid pressure from chamber 132 to leak past piston 136 and allow further spool movement which is only opposed by the low rate spring 130. A bypass valve 144 actuated by excess flow from outlet 20 acts to connect the two arms 46, 48 together. A relief valve block 164 acts as overload protection for the motor ports A, B.

Abstract: 402,748. Wedges. FERRANTI, Ltd., and MILLER, J. L., Hollinwood, Lancashire. April 30, 1932, No. 12511. [Class 89 (ii).] In a device for adjusting the position of a body in an evacuated container, such as the cathode of a cathode-ray tube, two wedge-shaped discs or blocks d, e are interposed between a lower disc f secured to the container b, and an upper disc c in which a rod a, carrying the cathode, is screwed ; the surfaces of the discs are maintained in contact by atmospheric pressure. A pin g on the rod a engages with a longitudinal groove h in the disc d to prevent turning. The following adjustments are possible :-(a) rotation of the upper disc c alone moves the cathode longitudinally, (b) rotation of the disc d with the disc c tilts the cathode, and (c) a sliding movement of the disc e with the discs d, c causes the cathode to be moved sideways or rotated. Means may be provided for restricting the freedom of movement of the discs and for ensuring that they cannot fall apart. In modifications the surfaces of the discs may be surfaces of revolution, for example, the contacting surfaces of the discs c, d may be conical, and the tilting movement may be produced by the relative movement of two members with spherical contacting surfaces.
