Abstract: 1282171 Bonded asbestos fabrics; lap forming apparatus TAC CONSTRUCTION MATERIALS Ltd 14 July 1970 [23 June 1969] 31651/69 Headings D1N and D1R A resin solution and asbestos fibres are sprayed simultaneously on to a backing sheet to form a mat. Small quantities of asbestos fibres are repeatedly added to hopper 22. Spiked creeper roll 24 conveys a constant quantity of fibres to where stripper roller 33 detaches them from roll 24 so that they fall into the inlet 34 of impeller 35. (Plate 27 and brush 28 remove excess fibres before they can reach the impeller). The fibres are blown by compressed air along tube 3 to the outlet of spray gun 1. Co-axially surrounding tube 2 is spray head 6, equipped with nozzles 7 which are angled slightly inwards towards the axis of tube 2, so that the streams of resin solution which they deliver mix with and impregnate the fibres before they impinge at an angle of 60‹ upon a hessian or wire mesh backing sheet (37, Figs. 4, 5, not shown). The spray gun is mounted on a carriage (36) which is moved transversely of sheet (37) by chain drive (38). Limit switches (39) halt the carriage at the extremity of its travel, move the backing sheet (37) a step forward and reverse the motion of the carriage. Alternatively the carriage may contain several spray guns, and the backing sheet may be moved continuously. Preferably a number of passes are made to build up the mat. The mat is rolled to consolidate and smooth it, removed from the backing sheet, then dried and precured in an air oven at 100‹C. The resin may be a polyester, silicone phenol formaldehyde or, cresol formaldehyde, but is preferably a 10 to 60% aqueous solution of a phenolic resin. Graphite or silicate fillers may be incorporated by mixing with the asbetos fibres.

Abstract: 466,212. Piezo - electric vibrators. SCOPHONY, Ltd., and JEFFREE, J. H. Nov. 21, 1935, No. 32258. [Class 40 (iv)] [Also in Group XL] In a device for generating mechanical waves of supersonic frequency in a body and comprising a piezo-electric crystal assembly having one face associated with the, body and adapted for excitation by electrical currents of the required frequencies, there is interposed between the face and the body an intermediate layer having an acoustic refractive index greater than that of the body and less than that of the crystal assembly, the layer having a thickness of one quarter wave length, or of an odd number of quarter wave lengths, at the frequency of resonance of the crystal element, and being in direct contact with the body. The acoustic refractive index of a material is defined as the product of its specific gravity and the velocity of propagation of sound in the material. The piezoelectric element may be a quartz crystal or the combination of a quartz crystal with steel plates. The intermediate layer may be of a single substance, such as that known under the Registered Trade Mark " Cellophane " or maybe constituted by interposed layers of Cellophane" and aluminium or by tin foil sandwiched between two layers of " Cellophane." The intermediate layer may be separated from the crystal assembly by an even number of layers, each having a thickness of one or of an odd number of quarter wave lengths, the material of the odd-numbered layers having an acoustic refractive index less than that of the even-numbered layers and of the crystal assembly, and the even-numbered layers having an acoustic refractive index greater than that of the substance forming the layer in contact with the body. For example, a combined quartz crystal and steel plate element may be separated from a layer of aluminium in contact with the body by layers of aluminium and steel. The piezoelectric device may be used in the light-modulating arrangement described in Specification 439,236, [Group XL].

Abstract: 819,946. Deodorizing &c., milk &c. CHERRY - BURRELL CORPORATION. Oct. 16, 1957 [Oct. 25, 1956], No. 32321/57. Class 49. Apparatus for the deodorizing of pasteurized milk or removal of peel oil from orange juice has a chamber 20, a chamber 21, a duct 51 communicating at its respective ends with the chambers, a liquid supply duct 37 for milk or juice controlled by a pressure-operated valve 36 and a withdrawal duct 63, a steam inlet 72, gas outlets 76, 88 from chambers 20, 21 respectively, and means for controlling the pressure in the chamber 21 independently of chamber 20. The liquid is preferably sprayed from a cone-shaped nozzle 40 into the chamber 20 which may incorporate a flow deflector 129 and baffle plates 127 (Fig. 12); after its treatment in chamber 20 the liquid flows by way of a throttling orifice (not shown) in pipe 51, enters chamber 21 through a tangential inlet and finally is discharged by a pump 71. Gas and vapour are withdrawn from chamber 20 into an exhaust header 83 through the outlet 76 which is connected to the side inlet of a tee 78 and a throttling disc 81 operable by a handle 86; similar connections are provided between chamber 21 and the exhaust header (Fig. 8, not shown) and include a vacuum relief valve 90 and petcock 92. The outlet port 93 of the header connects with the inlet 94 of a plate-type condenser 22 from which condensed vapour is withdrawn by a pump 112. Vacuum is maintained in the condenser, exhaust header and chambers by a pump 105 connected to the condenser by a pipe 103. In the deoderizing of milk, steam commingles and condenses with the milk whilst in the first chamber thus heating the milk to a temperature of 166-195‹ F. The lower pressure maintained in the second chamber causes evaporation of steam condensed in the milk and of volatile odour and flavour components, accompanied by a temperature decrease in the milk to 134-152‹ F. According to an example, in an apparatus adapted to handle 10,000 lbs. of liquid an hour, the chambers are 16 inches internal diameter and 36 inches in height. Specifications 413,460, 418,591, 485,241, [Group XIII], 525,488; 649,278, 674,032 [both in Group XIII], and 674,115 are referred to.

Title: A process for producing transparent effects on fabrics of regenerated cellulose
IPC: D06M11/38
Filed: 1945-11-30
Abstract: Transparent effects are produced on fabrics of regenerated cellulose by subjecting them first to a parchmentizing treatment with a swelling agent and then to a treatment with a solution of an alkali hydroxide at a temperature between 15-20 DEG  C., the alkali being removed as quickly as possible by, for example, washing with hot water.  Suitable parchmentizing agents are solutions of sulphuric acid, phosphoric acid, hydrochloric acid, zinc chloride and calcium thiocyanate.  Suitable alkali hydroxides are those of sodium and potassium.  Local transparent effects are obtained by first printing the fabric with a reserve which if desired may be dyed or pigmented. In the examples viscose muslin or regenerated cellulose staple-fibre is parchmentized with a solution of sulphuric acid containing, in one case urea, and, in another case, formaldehyde, at low temperatures. In one example a solution of phosphoric acid is employed as parchmentizing agent. The subsequent alkali treatment is effected with an aqueous solution of caustic potash and in one example, caustic soda.  In one example the fabric is primarily printed with a reserve comprising titanium dioxide, acetylcellulose, acetone, phenol and water.  Specification 577,233 is referred to.
