Title: Improvements in or relating to equipment for sports and gymnastic exercises
IPC: A63B61/00
Filed: 1960-03-15
Abstract: 922,308. Gymnastic and exercising apparatus; goals and nets. J. F. PROST. March 15, 1960 [March 17, 1959; Jan. 29, 1960], No. 9187/60. Classes 132 (1) and 132 (2). A container 1 for sand, stones or the like has a lid 2 and arms 5 supporting an upright sleeve 6 in which is received a graduated mast 7 held by a screw 8 which mast is adjustably engageable with an upright telescopic element 9 which forms an assembly to co-operate with further elements to provide appliances for use in sports and gymnastics. As shown, the metal container 1 is secured to the ground by lugs 4. A goal for hand-ball or football, Fig. 2, comprises two assemblies whose elements 9 carry adjustable sleeves 13 carrying respectively telescoping elements 11, 12 locked together by screws. More than two telescoping elements may be used for the cross-bar. In a net carrier, Fig. 3, for tennis or volleyball, the net tensioning cord is connected at one end to a hook on one upright and at the other end is carried over a pulley 17 on the second upright 9 and secured to an adjustable ring 18 on this upright. The lower ends of the net are connected to sliding rings 18 on uprights 9. A net hooked on a ring connected to a sleeve attached to an upright 9 forms a baseball post (Fig. 4, not shown). A stabilizing plate 27 bearing on the ground may be provided at the foot of sleeve 6. Alternatively, Fig. 10, upright 9 carries a fitting including two nets 49, and a board 47. Props (broken lines, Fig. 10) may be provided. In a jumping stand 1, Fig. 7, two extra long uprights 9 each carry an adjustable ring 28 with a bearing plate 30 to support the bar and a cone pulley 32. For training, a flat rubber belt C with bands of colour carried on the pulleys 32, is used instead of the bar B. Parallel bars may be formed by using two of the hand-ball goals side-by-side and connected by struts. The bars may be removed and a horizontal ladder put in their place.

Title: Improvements in and relating to weighing apparatus
IPC: G01G23/20
Filed: 1929-03-22
Abstract: 326,034. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). March 22, 1929. Computing-apparatus; indicating-mechanism.- In a weighing apparatus, errors of parallax in reading the chart are avoided by mounting the reading wire, strip or other index number so as to be movable towards and from the chart by hand from outside the casing and/or automatically. As applied to a drum scale, Figs. 1 and 2, the reading wire or strip 5 is stretched between two pivoted arms 6 operated by buttons 8 to move the wire into contact with the drum 1. Springs 9 return the levers. In a modification, the piston of an air cylinder 14, Fig. 3, is connected to the drum rack or other part of the weighing mechanism, and during a movement of the mechanism displaces air through either a suction valve 15 or a pressure valve 16 communicating with bellows 18, 25. The movable panels of the bellows displace a lever 21 and withdraw the reading wire 5 from the drum. When the weighing mechanism and the piston come to rest, a spring 23 restores the bellows to the original position with the reading wire applied to the drum. In a modification, two suction valves are arranged at opposite ends of the cylinder and the bellows operate on opposite arms of the lever 21. In a further modification, Fig. 4, the movements of the piston displace a valve-like member 29 within a bye-pass 28 so as to rock a contact lever 31 and close the circuit of a solenoid 37. The solenoid removes the reading wire 5 from the drum until the movements of the weighing mechanism cease. In a modification, one end of the contact lever 31 is located in proximity to an outlet of the air cylinder and is moved by the suction and pressure of the air passing in and out. In further modifications, the lever 21 is operated to remove the reading wire from the drum, by currents of air, controlled by valves at opposite ends of the cylinder, and acting either directly by suction upon the lever 21 or indirectly by pressure upon spring contacts in circuit with the solenoid 37. In a further modification, the air from the ends of the cylinder distorts a flexible diaphragm acting upon the lever 21 either directly, or indirectly through a contact lever and solenoid. In a further modification, Fig. 11, a vertical rod 48 depending from the scale pan 47 engages frictionally an arc 49 carried by the contact lever 31, and during movement of the weighing mechanism closes the circuit of the solenoid 37 so as to withdraw the reading wire 5. In a modification, the contact lever 31 assumes the form of a blade spring and is carried by but insulated from a counterbalanced lever through which the circuit is completed when the blade spring is vibrated by a link connection from the weighbeam. The cylinder may be hydraulic instead of pneumatic-

Title: Process for treating clays
Inventor: JONES GORDON KENNETH
IPC: B01J20/12
Filed: 1955-03-30
Abstract: An acid-activated montmorillonite clay, e.g. fuller's earth, suitable for use as a catalyst or bleaching earth is produced by mixing the clay with an acid, e.g. sulphuric acid, in the presence of water, extruding the mixture and forming pellets or nodules thereof, heating to activate whilst preventing loss of water and removing acid, water-soluble salts and water.  The clay may be thus treated after drying and grinding to a powder containing 2-15 per cent of water or as mined.  Activation may take place at 60-125 DEG  C. at atmospheric pressure in a water-saturated atmosphere for 1-32 hours or may be carried out under pressure: the pellets may be passed downwardly through a heated tower or through a continuous oven.  The acid and salts may be removed by leaching the pellets with water with or without previous grinding. The methods of Specifications 688,976 or 632,535 may be used after leaching to dry the product; the method of Specification 696,943 may be used to remove water, acids and salts; the wash water should not be above 80 DEG  C. and the operation may be performed countercurrently.  The resultant pellets (or the product of dewatering a slurry) may then be passed to a rotary kiln to reduce the water content to e.g. 0.1 per cent. Alternatively the moist activated pellets may be ground with water or a water-miscible solvent and spray- or film-dried.  In the examples a calcium montmorillonite and fuller's earth are employed.

Title: Improvements in and relating to the application of sound record tracks to films for the cinematographic projection of coloured and stereoscopic pictures
IPC: G03B31/00
Filed: 1936-03-30
Abstract: 456,110. Combined sound and picture films. KOLB, O. K., 39, Beverley Court, Wellesley Road, Chiswick, London. March 30, 1936, No. 9335. [Class 40 (ii)] Consists in various methods of applying to the production of optically reproducible sound - records on kinematographic colour picture or stereoscopic picture films, a process of recording in which an opaque layer is cut away mechanically to form a sound-track. Fig. 1 shows a film having a colour-screen layer 3 upon the sensitized emulsion 2. Along a zone 4, for the sound-track, the layer 3 is removed, and after the emulsion layer in the zone 4 has been rendered transparent by fixing, an opaque layer 5 is applied. Thereafter, sound is recorded mechanically by means of a cutter acting upon the layers in the zone 4. The colour screen 3 may be on the opposite side of the film base 1 to the light-sensitive layer 2, and is removed along the part of the film in the sound-track zone. Fig. 3 shows a colour film of the kind having a number of selective sensitized layers 2, 2<a>, 2<b>, an opaque layer for the mechanical recording of sound being applied to a portion of the layer 2<b>; the emulsion layers in the sound-track zone are freed from silver salts by fixation. In Fig. 5, a lenticular film is shown, in which the lenticulations in the region 7 opposite to the sound-track area have been abraded and replaced by transparent plastic material. An opaque lacquer 5, for receiving a sound record, has then been applied to the emulsion 2 on that part 4 of the film opposite to the smoothed portion 7, after the emulsion in the zone 4 has been made transparent. Specification 411,144 is referred to.
