Inventor: WALSH FRANK FORD PEREGRINE
IPC: G01P1/12
Filed: 1917-06-21
Abstract: 116,375. Walsh, F. F. P. June 21, 1917. Accelerometers and retardometers.- Apparatus for indicating and determining in magnitude and direction, without reference to any fixed external points, such as those of the horizon, a change in the normal velocity, path, or position of a body in motion, or at rest, comprises two nozzles a, Fig. 6, adapted to deliver horizontal streams of liquid from the reservoir f. The streams fall through a grating h and are conducted to a tank i from which the liquid is forced back to the reservoir by a centrifugal pump j. When the body is at rest or moving with a constant velocity, the streams are seen in plan as shown in Fig. 1, but a change in velocity causes them to follow the paths shown in plan in Fig. 4. Rotational movements about horizontal and vertical axes produce the effects shown in Figs. 3 and 5, and thus afford an indication of inclination. By the provision of suitable calibration marks, the change in velocity &c. can be measured, and the device may be employed to detect earth tremors.

Abstract: 666,769. Moulding refrigerator doors &c. from resinous material. GENERAL MOTORS CORPORATION. March 31, 1948 [April 2, 1947], No. 9076/48. Class 87(ii) [Also in Group VIII] An article which may be dish-shaped. e.g. a refrigerator door, is made by pouring a liquid thermosetting resin into a mould cavity 32 to cover the bottom 34, placing a lamina of fibrous material over the cavity to float on the resin, partly closing heated mould sections 28, 22, and then fully closing the mould to cure the resin. One section, e.g. the lower one, is at a higher temperature than the other. This higher temperature causes a gellation of a thin film of resin, during the first mould closing step, which gives the article a smooth surface. In order that pressure may be maintained on the resin during curing, a peripheral seal is provided which may be either (a) an integral metal lip 20 which also acts to cut the lamina or (b) a rubber seal, Figs. 6 and 7 (not shown). Excess resin which is not absorbed by the lamina may bleed from the mould through grooves in the lip 20 at the corners of the mould. The resin may be a mixture of alkyd polyesters and polymerizable hydrocarbons or a phenolic condensation product or a urea resin. The lamina may be sheeted glass fibre or cotton fibre. A comminuted filler may be added to give a desired surface finish. Such a filler is of spherical shape so that only small portions thereof touch the mould surfaces. The Specification as open to inspection under Sect 91 comprises also the use of polyvinyl chloride and polymethyl methacrylate resins. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the production of artificial threads, films and other products by wet spinning processes from solutions of cellulose esters or ethers
IPC: D01F2/28
Filed: 1931-03-27
Abstract: <PICT:0375423/IV/1> <PICT:0375423/IV/2> Artificial filaments, threads, ribbons, films, and similar products are obtained by extruding a solution of an organic derivative of cellulose into a coagulating bath and then directly subjecting the plastic product to a stretching operation, only a portion, or none of the stretching force being allowed to act on the product immediately upon extrusion. The organic derivative of cellulose may be cellulose acetate or other ester or ether of cellulose.  The spinning solution may contain acetone, acetic acid, ethylene or methylene dichloride with ethyl or methyl alcohol, diacetone alcohol, ethyl lactate, diethyl tartrate, or mono- or diacetin.  Spinning may be carried out at normal or raised temperature.  The coagulating bath or the spinning solution is such that the material passes through a plastic state in which it is stretched.  Aqueous or alcoholic diacetone alcohol, diethyl tartrate, acetin, ethyl lactate, lactic acid, dioxane, tricresyl phosphate, diethyl phthalate, methyl or ethyl alcohol, hydrocarbons, castor oil, salts, sugars, and other carbohydrates or alcohols may be employed in the coagulating bath.  The restriction of the stretching force may be effected by means of rods, or rollers, or by the movement of the coagulating medium. As shown in Fig. 3, filaments extruded from nozzle 7 are coagulated in a bath 8 and while still plastic are stretched between rollers 12, 13 which rotate at different speeds. The roller 12 rotates so that little or no tension is applied to the filaments on issuing from the jet.  In a modification the filaments pass round a small pulley before passing to a stretching roller.  In another construction, the filaments pass through a wire or glass grid and then to a stretching roller.  As shown in Fig. 4, the filaments pass through a fork tensioning device 17 and thence to a stretching roller 9.  By varying the inclination of the fork 17, the ratio of the tensions applied to the filaments before and after passage through the fork may be varied. Specifications 177,868, 179,234, [Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,436, and 343,062, are referred to.  The Provisional Specification includes also the application of the process to products of cellulose nitrate, and a modification in which the products after coagulation are rendered plastic by a separate treatment.  Specifications 334,838, 334,853 [both in Class 2 (ii), Cellulose &c.], and 340,437, are also referred to.
