Patent GB-814881-A (GB)
Title: Improvements in or relating to harvesting machines
Inventor: ROGERS HENRY BRYAN
IPC: A01F15/12
Filed: 1953-11-26
Abstract: 814,881. Baling-presses. MASSEY-HARRIS-FERGUSON (MANUFACTURING) Ltd. July 13, 1955 [Nov. 26, 1953], No. 32799/53. Clash 94(1). In a baling press in which the bales are automatically tied with twine, the twine leaves the supply device through an aperture which is smaller than any other aperture through which it passes prior to knotting and is engaged by a resilient device which normally retains it out of contact with a fixed knife positioned adjacent its path, the arrangement being such that a snarl or knot in the twine will jam in the aperture and the resulting overtensioning of the twine due to the operation of the tying needles will cause the resilient device to yield so that the twine is brought into contact with and severed by the knife. As shown, two lengths of twine 14 are fed from supply containers 15 to binding needles 35 of conventional construction, each length passing through an aperture 16, which is smaller than any other aperture through which the twine passes prior to knotting, an eye 24 in a resilient strip 21 mounted on a transverse rod 22, a tensioning-device 28-30, a resiliently-mounted eye 32, a fixed eye 34 and a guide 40 in the side of the bale chamber. The strip 21 is secured to a stud 27 passing through a cover plate 20 and encircled by a spring 26, whereby the twine is normally held clear of a fixed knife 25. If there is a snarl or knot 17 in the twine issuing from the container, it jams in the aperture 16 and the resulting increase in the tension of the twine when the needles are operated causes the strip 21 to yield so that the twine is severed by the knife and damage to the binding mechanism is prevented.

Title: Improvements relating to electron discharge devices such as television transmission tubes
Inventor: CASSMAN HARRY
IPC: H01J29/43
Filed: 1948-12-31
Abstract: 665,279. Electrode materials and processing. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 20, 1949 [Dec. 31, 1948], No. 33562/48. Class 39 (i). In sensitising the photo-electric mosaic in a sealed discharge tube, such as a television transmission tube, the screen is oxidized whilst it is exposed to a light image of different. intensity levels and is scanned to produce electrical signals, the oxidation being terminated when the signals indicate that a required degree of sensitization has been obtained. A pick-up tube, adapted to operate with cathode potential stabilization, has its mosaic support coated by the evaporation of antimony, or of bismuth and silver alternately through a mesh, the removal of which is followed by deposition of calcium. The tube is then evacuated and sealed, mounted in a camera and a light image of alternate black and white squares projected on to the screen. Oxygen may be released by heating a side tube or capsule containing potassium chlorate, barium oxide or silver oxide, which, alternatively, may form a coating on a platinum or tantalum heating ribbon. Oxidation is terminated when the difference in signal levels corresponding to the black and white squares in a television receiver is observed to be a maximum.

Patent GB-366602-A (GB)
Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T13/36
Filed: 1930-11-08
Abstract: 366,602. Fluid - pressure brakes. TOMLINSON, A. V., 65, Victoria Street, London.-(Westinghouse Brake Co. of Australasia, Ltd. ; George Street, Concord West, New South Wales, Australia.) Nov. 8, 1930, No. 33696. [Class 103 (i).] In fluid-pressure brake apparatus of the straight air type comprising a train pipe extending throughout a train of vehicles each having one or more driver's valves, communication between any driver's valve and the train pipe leading directly to the brake cylinders is established through a transfer valve which, when the driver's valve is in a position at which the operating handle can be removed, cuts off communication between the driver's brake valve and the brake cylinders. A driver's valve in the inoperative position when the handle can be removed, supplies fluid at full reservoir pressure to the transfer valve. The driver's valves 7, 8 at each end of a vehicle are in inoperative position and supply fluid from the reservoir 5 through pipes 25 .. 28 to the outer sides of pistons 14, 15 of the transfer valve 12, which are thus held in central position by spring abutments 31, 32, so that both driver's valves are cut off by a slide valve 19 from the connection 22 to the train pipe 9 and brake cylinders 6. The operating handle is placed on the driver's valve, for instance valve 7, from which it is desired to effect the control of the braking and the valve is moved to release position when the pipe 25 and the outer side of the piston 14 will be vented to atmosphere and the pistons 14, 15 will move to connect the passages 22, 25 by means of the cavity 34 in the slide valve 19. The brake can now be controlled through passages 25, 22. The pressure transmitted to the piston 14 through passage 27 on brake application is balanced by full reservoir pressure supplied to the other side of the piston through passage 26 until full reservoir pressure is supplied to the brakes and the passage 27 which with the pressure of the compressed spring 33 can overcome the pressure on the other side of the piston so that the pistons are not displaced until full reservoir pressure is supplied to the brakes. Leakage grooves 35 balance the pressure on the pistons in central position. In a modified form of transfer valve for vehicles having only a single driver's valve each, one piston is used which holds the valve in inoperative position against spring pressure.

Title: Wrapping device
IPC: B65B49/08
Filed: 1960-09-30
Abstract: 953,551. Wrapping-machines. H. GAMBLE. Sept. 30, 1960 [Oct. 1, 1959], No. 33703/60. Heading B8C. Apparatus for folding a projecting end of a wrap of sheet material applied around a generally rectangular package into end closure flaps over an end face of the package, including a folding shoe mounted on a support for pivotal movement over the end face of the package, the shoe having a curved operating face and a pair of coaxial rollers mounted on the shoe for movement therewith and located in front of a leading edge of face 6 and being axially spaced apart. The folding shoe 5 comprises a quadrant arm carrying cheek 6 and mounted on shaft 20 which oscillates. Pivoted at 27 on the arm 5 is a lever 26 having a roller 28 pressed by spring 29 on to a fixed cam edge 30 so that as the arm 5 oscillates, rollers 24, 25 on the lever 26 move along a linear path across the end face of the package 2. In operation the package 2 is moved by a ram along a platform past the shoes while they are in the position shown in Fig. 1, thus folding down the flaps 7 in Fig. 1a. The shoes are then swung out of the way of the package which is stationary while the longitudinal margins 1a of the wrapping are folded down on to the side of the package in any desired manner. The shoes then swing backwards so that the rollers 24, 25 and cheek 6 fold down the parts of the wrapper 1 which project beyond the end of the package 2, thus completing the package ready for sealing. The fixed cams 31 may be adjusted by a screw 32. For different heights of package, suitable spacing members may be used to separate the rollers 24, 25.

Abstract: 1363501 Boring earth &c SCHLUMBERGER INLAND SERVICES Inc 19 July 1971 [30 July 1970 (3)] 33742/71 Heading E1F [Also in Division Fl] Signals generated at the bottom of a drilling hole and representing measurements of drill weight, torque, borehole temperature and the like are transmitted to the borehole head by periodically closing a normally open obturating valve 41, 45, Figure 2, in the path 37, 38, 40 of down flowing drilling fluid in response to data signals; the valve portion 45 being moved towards its closed position by a solenoid 58 which when energised depresses a headed rod 43 against a spring 55 thereby placing the valve 45 in the flow path after which the rod 43 is further depressed into a bore 40 by drilling fluid pressure until a shoulder 48 of rod 43 depresses a head 49 of valve portion 41 thereby depressing the latter against a spring 56 to a position in which fluid port 38 is fully closed after which due to fluid pressure equalisation spring 50 lifts valve portion 45 and spring 56 lifts valve portion 41 thus allowing continued flow of drilling fluid through port 38. A turbine 30 upstream of the valve 41, 45 and driven by the drilling fluid continuously drives a generator 32 which provides electrical power for operating data-signalling means and hence the solenoid 58. In a modification, a valve 106, Figure 9, is held in the open position against a spring 124 by spring latch fingers 113 engaging lugs 114 on the valve stem 110 and when the latch is released on energising a solenoid 116 the valve 106 is depressed below a fluid inlet port 105 and then, due to the pressure rise in port 105,. the valve is further depressed into a slidable tube 107 which latter is then itself depressed by said fluid pressure rise to a position below the valve 106 thus equalising fluid pressure above and below valve 106 which latter is then returned by spring 112, to the latched position shown; solenoid 116 by this time being deenergised. In a further modification a sleeve valve (243) Figure 11C (not shown) is continuously rotated by a turbine driven generator shaft (250) Figure 11B (not shown) which is spliced to the valve stem (268). The valve is lowered to its closed position by a solenoid actuated rocking pawl 256 engaging a thread (254) on shaft (250) and is returned by spring means disengaging the pawl.
