Title: Improvements in gramophones
IPC: G11B17/16
Filed: 1944-03-13
Abstract: 582,008. Magazine gramophones. AKTIEBOLAGET GYLLING & CO. March 13, 1944, No. 4679. Convention date, April 15, 1943. [Class 40 (ii)] In a magazine gramophone of the kind in which the records to be played are stacked on an offset shoulder on a post extending axially of the turntable, the stack has fixed and movable edge supports, the movable support being latched on the fixed support, but being released when a record of large diameter is lowermost to allow the record to fall The release of the latch serves to set the tone-armpositioning mechanism. In Fig. 1, plate 9 is the movable support pivoted at 10 on the fixed support 8. Support 9 is normally latched in record-supporting position by a latch 11 mounted on the fixed support and having a nose 13 engaging a projection 14 on the support 9, and a projection 15 extending into the path of a record of large diameter. Latch 11 is normally held in the position shown by gravity, but upon the latch being moved by pressure of a record on projection 15. support 9 drops. This allows a record to fall and operates through an extending rod 19 a bar 18 which extends below the motor board 1 and has a projection 18<1>, Fig. 5, engaging in one end of a lever 24, 25. connected to a further lever 26 formed with a flag 27 which is moved into the path of a two-position projection 28 on the cam disc 2 controlling the automatic operation of the machine. Projection 28 engages on arm 37, Fig. 3 (not shown), rigid with the tone-arm, to swirig that arm, and the position to which projection 28 is adjusted determines the loading position of the pick-up. Support 9, bar 18 and lever 24, 25 are reset by engagement of a cam 16 on disc 2 with bar 18. Projection 28 is also reset to position the pick-up for loading on a small record after a large record has been played by engagement with a fixed projection as disc 2 rotates.

Title: Improvements relating to automatic packing and weighing machines
IPC: B65B59/00
Filed: 1936-02-17
Abstract: 466,911. Automatic - feed weighers. SOUTHALL & SMITH, Ltd., PARTRIDGE, R. B., and WEAVER, F. W. Feb. 17, 1936, No. 4747. [Class 143] An automatic machine for charging receptacles with powdered &c. materials comprises a supply hopper having a discharge nozzle, a weighbeam mounted on a platform, vertical rotatable screws for carrying the platform and for enabling the platform to be vertically adjusted to raise or lower the weighbeam relatively to the nozzle for accommodating receptacles of different heights, and gearing whereby the screws may be rotated from a common operating handle or hand wheel. The weighbeam is fulcrumed on brackets on a platform c which may be raised or lowered by means of two intergeared screws d rotated by a hand wheel h so as to adjust the distance between the scale pan k and the feeding nozzle l. When an empty receptacle is placed on the pan k, and a pedal-operated rod r is depressed, a plate t on the rod actuates a bell-crank lever u and couples up a clutch q. The clutch drives a stirrer 10 and a worm n to feed the material to the receptacle. When the required weight has been supplied, the scale beam rocks and breaks the circuit of an electromagnet 3 thereby allowing its armature z to be moved away from the magnet by a spring 2. The spring at the same time rocks a lever w and disengages the clutch thereby stopping the feed of material. The pedal-operated rod r, during its descent is pushed laterally out of engagement with the lever u by means of roller 5 on the frame to permit disengagement of the clutch by the spring 2. A spring s returns the rod r to its upper position. A supplementary weighbeam 12 may be brought into action by removing a pin when heavy receptacles are being charged.

Title: Paper makers wet felts
IPC: B32B7/02
Filed: 1973-01-31
Abstract: 1455843 Laminates SCAPA-PORRITT Ltd 24 April 1974 [31 Jan 1973] 4780/73 Heading B5N [Also in Division D1] A paper-makers felt comprises one endless belt formed from a body of non-woven fibrous material having a hydrophobic surface layer having a surface energy of less than 33 dynes/cm., and a backing layer which is thicker and of greater water take-up capacity than the surface layer. The hydrophobic layer may consist of intrinsically hydrophobic fibres (polytetrafluoroethylene, fluorinated ethylene-propylene copolymers, polypropylene or blends thereof or with non-hydrophobic fibres (wool, nylon or polyester). Hydrophobic character can alternatively or additionally be produced by the application of hydrophobic material to the fibres before formation of the layer or in the layer. A polysiloxane or fluorine containing polymer may be adhered to the fibres. Alternatively a chemical bond is effected between the fibre and the hydrophobic agent. Polyamide fibres may be treated with a solution of triphenylmethane triisocyanate or 2,4 or 2,6 tolylenediisocyanate followed by vinyl fluoride, pentadecafluorooctylacrylate or polydimethylsiloxane prepolymer. Fibres may be treated with pentadecafluorooctylacrylate, vinyl fluoride or polymethylsiloxane prepolymer in the presence of a free radical former such as t-butyl peroxide, dibenzoylperoxide, hydrogen peroxide, peracetic acid, persulphates and cerium salts or proceeded by treatment with ozone. Polyamide polyester or polyolefin fibres may be treated with difluorocarbene generated by in situ pyrolysis of sodium chlorodifluoroacetate or chlorodifluoroacetic acid. Silicone oil or a compound containing 1 to 4 fluoroalkyl groups attached to an organic radical may be added to the melted polypropylene to produce fibres having a surface energy of 26 dynes/cm. rather than 32 dynes/cm. In Example 1 the belt comprises a base layer woven from polyester and polyamide yarns, an intermediate layer formed by carding 6 cm. polyamide fibres and a surface layer formed by carding 6 cm. polypropylene fibres. The layers are laminated together by needling a solution of an air-curing polydimethylsiloxan is applied to the polypropylene surface by a lick roller. In Example 2 the polydimethylsiloxan is applied to the polypropylene fibres before they are carded. In Example 3 the surface layer consists of polyamide fibres treated with pentadecylfluorooctylacrylate and t-butyl peroxide. In Example 4 the intermediate layer comprises 60% polypropylene and 40% wool, the polypropylene fibres used to form the face and intermediate layers being treated with ozone and then with polydimethylsiloxane.

Title: An improved method of producing cellular concrete and the product thereby produced
IPC: C04B28/26
Filed: 1945-02-26
Abstract: Cellular concrete is prepared by adding to the cement mix a foam which has been treated so that any chemical therein normally reactive to the ingredients of the cement mix has been rendered substantially inactive, so that the properties of the concrete are not affected. An ordinary concrete mix is prepared with sufficient water to produce a friable mass without rendering it flowable.  A resin soap is prepared by boiling rosin with an aqueous solution of sodium or potassium hydroxide; alternatively, the resin soap may be partially or wholly replaced by a soluble oleate, palmitate, or stearate.  To produce a firmer foam with smaller bubbles, there is added a mucilage prepared by soaking alkali-soluble casein in cold water and adding ammonia and stirring, about 3 per cent. of the weight of the casein of sodium penta-chlorophenate being added as a preservative if necessary.  A solution in hot water of the soap or soap-caseinate mixture is prepared, the concentration varying from 0.5-20 per cent. and is beaten to produce a foam of the desired consistency and is then treated, with gentle agitation, with an agent which forms water-insoluble bubble pellicles and renders inactive towards the cement-mix ingredients any chemicals in the foam.  Any soluble metal salts capable of replacing the basic constituents of the soap or caseinate compound may be employed, e.g., chromium salts, iron sulphate, lime water, or, preferably, aluminium sulphate or calcium chloride.  Solutions of up to 10 per cent. concentration may be used. To increase the water-repellent properties, foam containing a higher percentage of soap, or ammonium, calcium, or aluminium stearate may be added.  The foam is then allowed to drain; if necessary, it may first be sprayed or washed with warm water to remove any excess of the reaction products.  The liquid which drains off may be pumped back over the foam or applied to another batch.  Sufficient foam is added to the cement mix to produce the desired volume increase, e.g., from 2 to 6 times the original and the incorporation is effected slowly at first to prevent breaking-down of the bubbles, and, when they have become coated, more rapidly.  Hardening and quick-setting agents such as sodium or potassium silicates may be added to the mix, but preferably the set concrete is treated with a solution of the silicate, to which colouring matter may be added, as by spraying, brushing, or immersion.  To insure rapid impregnation, the concrete is immersed in the silicate solution in a chamber to which a vacuum is applied.  The concrete should then be washed with water to remove any caustic soda produced by the reaction or residual sodium silicate.
