Title: Agricultural implement
Inventor: JOLLY ARTHUR ARNOLD EDWIN
IPC: A01C3/04
Filed: 1947-08-06
Abstract: 644,056. Load-handling machines. BENTALL & CO., Ltd., E. H. Aug. 6, 1947, No. 21479. [Class 78 (iii)] An agricultural implement for use with a tractor comprises a wheeled chassis, a post on the chassis, a jib-boom supported at the lower end of the post for slewing movements, a telescopic head provided with a tool-attaching fitment carried by the jib-boom, which head is controlled by a hydraulic ram contained within the jib-boom, and a second hydraulic ram anchored to the post and connected at its other end to the jib-boom, for raising the latter. The post 7, secured to a rigid frame 1, is provided with a sleeve 8 which supports the jib 25 and second ram 11 at its lower and upper ends respectively. The upper portion 26 of the jib contains the ram for extending the telescopic head. The head comprises a box 40, Fig. 3, having a medial plate 50 on which is pivoted a catch lever 45, Fig. 4, releasably engaging a pin 48 on the tool, for tipping the latter. The tool is a fork pivotally attached by a rod and sleeve 39. A pair of chains 49 limit the tipping movement. The machine is operated by lowering the jib, extending the fork into material to be moved, raising the jib, tipping, and finally retracting the fork. The retraction of the fork causes it to be restored to its material-engaging position by providing an arm 51, secured to plate 50 and having a sprocket 53 at its end which runs on a rack 54 secured to the jib. The rotation of sprocket 53 rotates a pulley 52 winding in a short rope 56 passing to an anchorage 58 on the fork. The hydraulic cylinders are controlled from separate levers 33, 34, and a wheel 21 is coupled via its shaft 22 and sprocket connection 23 to a sprocket-wheel 24 secured to sleeve 8 so that the jib can be slued. A balancing weight 16 is placed in a triangular framework secured to sleeve 8. The hydraulic conduits pass through the centre of post 7 which is hollow.

Abstract: 597,560. Valve holders. JACKSON, D., and PYE, Ltd. Aug. 23, 1945, No. 21559, [Class 38 (i)] To improve screening, a valve holder comprises a one-piece moulded body 10 having contact apertures 16 and bosses 11 which enter corresponding apertures in a metal plate 13 to which the body is secured by a rivet 23 which is conductively connected to the plate. A slot 24 in the rivet is aligned with a key-recess 22 in the body for the guide-pin of a valve, and a flange 26 engages a shoulder 33 on the body 10. The rivet portion 27 is provided with resilient tongues 28 compressible by a C-spring 29 to ensure a good contact with the valve guide-pin. The contact elements are of the type described in Specification 595,220. The Provisional Specification describes a rivet shaped to conform with the guide-pin aperture, and an arrangement in which the flanged portion of the rivet houses a spring clip adapted to snap into a groove in the valve guide pin. The Provisional Specification also refers to Specification 595,186.

Abstract: 882,579. Making forming screens for pulp moulding dies. DIAMOND NATIONAL CORPORATION. June 20, 1960 [July 17, 1959], No. 21601/60. Class 83 (2). A method of preparing metallic cloth for use as screening on a pulp forming die comprising the steps of corrugating said cloth and forming it to make a screen for the die. The cloth C is passed between grooved rollers 11 and 12 to form corrugations and then turned through 90 degrees and passed through again. Before the second pass the gap between the rolls is increased by adjusting the screws 18, only one of which is shown. The corrugated cloth is then formed in two stages in a forming die, prior to each stage the cloth is heated to 1000‹ F. and cooled in still air. Fig 5 shows a typical forming screen produced by the method.

Abstract: 1428920 Sterilisation MORTON-NORWICH PRODUCTS INC 15 May 1974 21637/74 Heading A2D [Also in Divisions A5 and C7] A bactericidal solution is made by electrolysis of aq. NaCl at pH 6-7, whereby nascent Cl 2  is generated, at least 80% of which is in the form of HOCl, and the solution is immediately applied to a bacterialaden surface e.g. a meat carcass. The NaCl solution may be acidified with 85% HAc to give a Cl content in the product of 25-2000 ppm. Apparatus for preparing and distributing the solution includes a tank containing solid NaCl and in which a saturated solution is maintained, acid and water being automatically added in manually-adjustable amounts to give the pH required. The acidified solution, with up to 100 parts of additional water, is pumped to an electrolysis cell having an anode of Pt, an alloy thereof, C or Pbo 2  and a cathode of Ni or Ti, the electrodes being supported between PVC spacers. A baffle in the cell prevents pulsating fluid from the pump passing directly between the electrodes. A portable spray wand is connected to the cell output and has electric switches for operating the electrolysis process or providing a flush of pure water, suitable circuitry being described.

Patent GB-755068-A (GB)
Title: Improvements in or relating to method of making catalysts
IPC: B01J21/12
Filed: 1954-07-27
Abstract: Silica-alumina catalyst containing 20-50 per cent by weight of alumina is prepared by allowing partial polymerization of a silica hydrosol at a pH between 3.5 and 5.5, then adding an aqueous solution of an aluminium salt containing free acid, neutralizing the mixture, and drying, washing, and redrying the silica-alumina hydrogel formed. The silica hydrosol may be prepared by mixing a solution of sodium or potassium silicate with sulphuric, hydrochloric, or nitric acid; for example a sodium silicate solution having a concentration equivalent to 3-6 per cent by weight of SiO2 and a Na2O : SiO2 ratio of 1 : 1 to 1 : 4 is mixed with sulphuric acid of 10-60 per cent concentration. An alternative method of forming the silica hydrosol is to pass sodium silicate solution through a cation exchange resin.  The hydrosol may be allowed to polymerize for about half the setting time of the silica.  Suitable aluminium salts are the sulphate, nitrate, and chloride; the sulphate is preferred and may be used as a 20-25 per cent solution containing 1-4 per cent of free sulphuric acid. After addition of the aluminium salt solution, the mixture has a pH of 1-3 and is treated with aqueous ammonia to a pH of about 7, with vigorous agitation: the gel slurry is filtered, dried, washed with an alkaline liquid, and dried again.  In an example the washing of a portion is carried out with ammonia solution and of another portion with sodium carbonate solution followed by ammonium sulphate solution.  A comparative experiment in which ammonia was added to a pH of 8.5 yielded a poorer catalyst.  The catalyst is useful in the cracking of hydrocarbons and exhibits higher stability to steam and greater resistance to contamination than other high alumina catalysts.

Abstract: 987,111. Shock absorbers. BORGE G.m.b.H. June 21, 1961 [July 9, 1960; Feb. 13, 1961], No. 22508/61. Heading F2S. A telescopic shock absorber comprising a piston 4 which works in an oil-filled cylinder 1 and carries a cylindrical compensating chamber 9 consisting of an elastic bellows 11 within an air container 19 is characterized in that throttling bores 5 all have a restricted, high-velocity flow, area which is connected, e.g. by means of a channel 7, with the compensating chamber 9. The outward flow of oil from the compensating chamber 9 during a rebound stroke of the piston may be accelerated by providing at least one additional outlet 12 which is closed by a spring-loaded check valve 15 when the oil flow is reversed. The bore shape can be modified to give different suction and throttling effects in the compression and expansion directions. As shown in Fig. 3 an annular channel around the throttling bore 33 leads to a pipe 35 which is connected to the reservoir chamber 9. In a modification, Figs. 6, 7, the restriction in the throttling channel 105 is formed by the edge of a disc 136 which partially covers the upper outlet of the channel 105 and also covers the upper face of a duct 107 and an annular groove 135 leading to radial bores 123 in a hollow piston rod 103 the upper end of which is enlarged to form a compensating chamber 109 having a floating piston 111. The disc 136 has offset portions 140 which serve as abutments for valve springs 121 whichh are adjustable by set screws 122 and act upon valves 117 which control openings 120. In a further modification the valve discs of disc valves are used to provide the restrictions in the throttling bores. The air around the compensating chamber may be maintained under increased pressure in which case the shock absorber may be used e.g. as a compressed-air landing leg.
