Abstract: 663,677. Regulating How of liquids. TR1GGS, W. W., (Wyandotte Chemicals Corporation). Aug. 19, 1949, No. 21588/49. Class 135 [Also in Group XXXV] In a device for controlling the amount of chemical in an electrically conducting solution (e.g. alkaline detergent) in dish-washing water (see Group XXXV), the solution is circulated for testing and if below strength is diverted by a chute to a compartment S, containing the solid chemical supply. Test and Flow Diversion (Compartment V) Solution is pumped from the dish-washing machine through pipe 4 into chamber 12 containing the test electrodes 26 (shown as a sparking plug), and overflows past the baffle 13 when it either returns directly to the machine through pipe 5 or is diverted through the solid chemical compartment, according to the position of a chute 19 hanging from a bracket 22 so that it is pulled beneath the overflow from chamber 12 when an electromagnet 25 in compartment V is energised, and swings back by gravity when released. Chemical Supply (Compartment S) The solid chemical is stored in a removable perforated container 30, with a detachable sludge pan 34 under. When the solution is diverted through compartment S it dissolves some of the chemical and returns to the dish-washing machine through pipe 6.

Title: Improvements in non-resinous condensation products
IPC: C08G8/28
Filed: 1945-08-23
Abstract: Thermosetting non-resinous liquid condensation products are prepared by heating phenol or an alkyl phenol with formaldehyde and an alkaline catalyst, neutralizing the mixture with a weak acid and removing excess formaldehyde by reacting the mixture with a salt containing a sulphite radical and separating the sulphiteformaldehyde addition product.  Phenols specified are phenol, m-cresol, p-ter-butyl phenol, 1 : 3 : 5-xylenol.  The phenol in each case is condensed with neutralized formaldehyde with sodium hydroxide as a catalyst, the mixture being then neutralized to methyl red (pH 5.5 to 7.5).  Sodium bisulphite is then added, the layers separated and in examples 1, 2, 5, 6 the product is dehydrated under reduced pressure, products from examples 3, 4, 7, 8 containing only small amounts of water.  From each phenol products of differing viscosity result by variation of the time of condensation.  Paraformaldehyde may be used in place of formaldehyde solution, other suitable acids for the neutralization are glycollic, acetic or benzoic, and suitable sulphites are the sulphite, bisulphite or metabisulphite of an alkali- or alkaline-earth metal.  The products may be used as pigment vehicles in coating compositions and in printing inks and as adhesives for veneered and other laminated products. Specification 599,835 is referred to.

Filed: 1967-05-10
Abstract: 1,131,373. Calenders. FARREL Corp. 10 May, 1967, No.21660167. Heading D2A. A doctor blade acting on a roll for calendering, e.g. paper is carried on a sleeve diposed about a rotatable shaft and supported thereon at its ends. The shaft also carries means defining with the shaft and sleeve a cavity into which fluid can be introduced under pressure to correct the bowing of the doctor blade that would otherwise occur. As shown, doctor blade 22 acting upon roll surface 11 is mounted on a carrier 24 mounted on sleeve 25 by means of ribs 26. The ends of the sleeve have caps 28 (fig. 4, not shown) receiving bearings on the rotatable shaft 27. Mounted on the shaft are strip members 38 and 39 bearing on lugs 40, so that when the shaft is turned in the direction of the arrow A, the tip of the blade 22 is moved towards the roll. Sleeve 25, shaft 27 and strip members 38 and 39 bound a cavity in which is an expansible bladder 43, with a fluid inlet 44. When fluid -is supplied under pressure, the sleeve 25 and therefore also the doctor blade 22 tend to bow with their centres closer to the surface 11 than their ends are. By adjustment of the pressure, this can be made to compensate partly or fully or overcompensate for the bowing in the opposite direction due to the support of the blade carrier at its ends. An hydraulic circuit is described (fig. 7, not shown) for the control of this pressure and also of hydraulic cylinders applying pressure to the blade by turning the shaft 25.

Title: Process for improving the whiteness of acrylic fibres and films
IPC: D06P3/76
Filed: 1959-06-26
Abstract: Acrylic fibres and films, i.e. fibres and films made from a homo-polymer of acrylonitrile or a copolymer or mixture of polymers containing from 85% to 100% of acrylonitrile in their molecule, the remainder being one or more copolymerizable ethylenic compounds, and fabrics or articles made from or containing such fibres, are whitened by impregnating them with a solution containing at least one salt of chloric acid and at least one acid compound capable of liberating chloric acid from a chlorate at room temperature or on warming, and then subjecting them to a steam treatment.  The fibres are preferably impregnated at room temperature or slightly higher temperatures, centrifuged or squeezed and then dried at temperatures of the order of 20 DEG -60 DEG C.  They are then steamed, preferably at temperatures above 100 DEG C.  Specified acid compounds are strong acids, e.g. sulphuric, phosphoric, sulphamic and sulphonic acids, their acid salts, e.g. sodium bisulphate, and derivatives thereof capable of hydrolysis, e.g. aluminium sulphate and ethyl sulphate. Specified chloric acid salts are the chlorates of the alkali and alkaline-earth metals and of aluminium, cadmium, cobalt, copper and zinc.  The process may be used to whiten unbleached acrylic fibres or to counteract the tendency of acrylic fibres to yellow in the course of steam treatments applied in operations such as printing and dyeing.  Examples describe the impregnation of fabrics with solutions containing chlorates and acid compounds which are subsequently centrifuged, dried, printed with basic dyestuffs and steamed to produce prints upon backgrounds which remain very white.  If dyes which are particularly sensitive to oxidation are employed, a reducing or anti-acid compound, e.g. sodium hyposulphite, may be added to the printing paste.  Fabrics or articles containing acrylic fibres in admixture with other fibres, e.g. polyesters or cellulose triacetate, may be treated.

Title: Improvements in and relating to radial flow elastic fluid turbines
IPC: F01D1/28
Filed: 1933-08-08
Abstract: 403,335. Steam turbines. FAIRWEATHER, H. G. C., 65, Chancery Lane, London.-(Allmõnna Svenska Elcktriska Aktiebolaget ; Vasteras, Sweden). Aug. 8, 1933, No. 22187. [Class 110 (iii).] Relates to the arrangement of the discs provided in radial flow turbines for packing and end-thrust balancing purposes, particularly in turbines to which steam is admitted at one side only. Fig. 1 shows a turbine having oppositely-running rotors 1 to which steam is supplied on one side by a pipe 5. In front of the labyrinth packing between the rotating disc 9 and the fixed disc 10 is arranged a packing between the disc 10 and a rotating disc 6. This latter disc may carry inward flow blades 7. Channels 11, 12 connect intermediate points in the labyrinth with the blade system 4. The arrangement is such that this rotor is substantially balanced for end thrust. The labyrinth packing carried by the discs 13, 14 for the other rotor is arranged so that a thrust bearing may be dispensed with. An intermediate space is connected by a channel 15 with the blade system. At the inner periphery the packing is connected by an injector-like channel 17 with a space 16 which is in communication with the condenser system. Leakage of air &c. inwards is thus prevented. A labyrinth shaft packing may be arranged at this point, where also steam may be introduced from the entrance to the blade system 4. At low loads fresh steam may be introduced into the packing by a channel 20 to maintain the balance. The turbine may have steam admission on both sides, and the invention may be applied to single rotation turbines.
