Title: Phenolic resins and their use in moulding processes
Inventor: SMITH ERIC
IPC: C08L61/10
Filed: 1955-06-06
Abstract: Sand particles are coated with a phenolic resin prepared by condensing phenol and formaldehyde in a mol. ratio of from 1 : 1.3 to 1 : 1.5 in the presence of ammonia, by dissolving the resin in a solvent, e.g. methylated spirits, mixing with sand and evaporating off the solvent.  In Example 2, a resin prepared by condensing together phenol, aqueous formaldehyde, aqueous ammonia and caustic soda was dissolved in methylated spirits, sand being added and the solvent evaporated at 65 DEG  C.  The slightly aggregated product was slightly ground with pestle and mortar. The resulting product may be used in the preparation of shell moulds.ALSO:A composition for use in shell moulding processes comprises a mixture of a finely-divided refractory material and a phenolic resin, prepared by the condensation of phenol and formaldehyde in the proportion of 1 mol. phenol to from 1.3 to 1.5 mols. of formaldehyde in the presence of ammonia.  Specified refractory materials are sand, sillimanite or fireclay.  Resin of a sufficiently small particle size can be mixed directly with the refractory material or the resin can be dissolved in a solvent, e.g. methylated spirits and mixed with the refractory, the solvent being removed by evaporation.  In the examples: (1) phenol, aqueous formaldehyde, aqueous ammonia and sodium hydroxide were mixed and heated, the liquid resin being allowed to cool and solidify and then crushed.  The resin then being mixed with sand; (2) the resin of Example (1) was dissolved in methylated spirits, sand added and the solvent evaporated at 65 DEG  C.  The product was lightly ground.  Examples 4 and 5 describe the preparation of shell moulds from the compositions by conventional processes.ALSO:Finely divided refractory material, e.g., sand, sillimanite or fireclay is mixed with a phenolic resin prepared by the condensation of phenol and formaldehyde in a mol ratio of from 1 : 1,3 to 1 : 1,5 in the presence of ammonia to produce shell moulding compositions.

Filed: 1928-06-05
Abstract: 294,235. Henkel et Cie Ges. July 21, 1927, [Convention date]. Addition to 244,708. Starch.-The process of making dry &c. halogen-calcium starch preparations, soluble and without lumps, described in the parent Specification, and consisting in adding borax in amounts up to 2 per cent by weight of the starch used, to the preparation before or after setting has taken place, is modified by adding, in place of borax, calcium borates or boric acid compounds adapted to form in the calcium-halide starch masses, difficultly soluble calcium borates. In examples (1) Potato flour is stirred with a calcium chloride solution, and to the thickened mass is added up to 2 per cent of calcium borate. The mass is then allowed to solidify, and if subsequently mixed with cold water, forms a paste free from lumps. (2) Calcium chloride starch is made as in Example (1), but calcium hydroxide is present with the ,calcium chloride. Boric acid, up to 1.5 per cent, is added before solidification occurs, to produce calcium borate. (3) Calcium chloride starch is made as in Example (1), but up to 2 per cent of sodium meta-borate is added to the paste. The calcium borates or the additions from which they are formed may be ground with the solidified calcium halide starch.

IPC: G11B17/02
Filed: 1928-06-05
Abstract: 316,731. Gramophone Co., Ltd., and Clark, G. F. June 5, 1928. Brakes, arrangement of. - Automatic stop mechanism comprises a movable member such as an arm 8 moved bv the tonearm, and a second movable member such as an arm 13 in frictional engagement with the first, the second member being held stationary during movement of the tone-arm in one direction and moving, by virtue of its frictional contact with the first member, to operate a stop device when the movement of the tone-arm is reversed. In the form shown, a pin 7 moving with the tone-arm 3 is en gaged between spring jaws 11, 12 as described in Specification 249,452. Moving with the jaws 11, 12 about the axis 9 is the arm 8 and the forked end of the arm 13 engages over a pin 16 on a stop member 17. This member is movable about a pivot 18 between stops 19, 20 and engages projections 31 on a braking-sleeve 29 surrounding the turntable spindle. During tracking the arm 13 remains fixed but, when the movement of the tone-arm is reversed due to the stylus engaging an eccentric groove in the record, the arm 13 moves the stop-lever 17 to the position shown to stop the turntable. Further movement of the tone-arm in the same direction to the commencing groove of the record causes the arm 8 to ergage the end 21 of the lever 17 to remove the stop from the sleeve 29 to start the rotation of the turntable. Friction between the sleeve 29 and the hub 23, Fig. 4, on the turntable 2 is obtained by fibre pads 27 pressed outwards through recesses in the hub to engage a groove 30 on the inside of the sleeve 29.

The binder layer may also include a further thermoplastic heatactivatable adhesive methyl methacrylate/ ethyl acrylate/methacrylic acid copolymer or (as shown) the sheet 11 may be coated with a thermoplastic heat activatable acrylic acid/isooctyl acrylate copolymer layer 14. In a preferred method of making the sheet, a monolayer of microspheres of glass is partially impressed into the polyethylene of a heated polyethylene-coated paper temporary support. The protruding surfaces of the microspheres is then vacuum coated with ZnS. The coated microspheres on the temporary backing are then coated with binder composition. When the composition dries the temporary backing is stripped. The reflective sheet may be adhered to the back of a photograph, for example.

In the example shown, the shoot f leads to a testing shoot a of the kind described in Specification 305,161, [Class 27, Coin-freed apparatus &c.], into which the coins enter in single file. The superposed coins bear on one side wall of the shoot f, the friction between the innermost coin and the wall being comparatively large so that the outermost coin travels more quickly than one nearer the wall and the set is dissolved into a series of coins running after one another. If the coins stick together, the point of a screw g projecting from the bearing wall into the shoot jars the set of coins to separate them. Several screws g may be employed. Specification 309,705 is referred to.
