Abstract: 351,702. Hair-drying apparatus. FUCHS, C., 12, Schifflõnde, Zurich, Switzerland. May 28, 1930, No. 16460. Convention date, May 29, 1929. [Class 131.] An air douche for drying the hair comprises a gauze or like hood 9 mounted on an air-conducting pipe 8 and enclosed by a framework of pipes 12 having nozzles 13.

Title: Improved temperature responsive electric switch
IPC: H02H7/085
Filed: 1952-07-01
Abstract: 703,308. Protective cut-out arrangements; thermal switches. GENERAL MOTORS CORPORATION. July 1, 1952 [July 13, 1951], No. 16498/52. Addition to 591,634. Class 38(5) In a modification of the motor control device according to the parent Specification the thermoresponsive device which shunts part of the current to the control device during normal running of the motor is inoperative during starting and is rendered operative by the opening of the starting winding circuit. A rigid frame 20 carries leaf springs 22, 23, the former carrying opposed contacts 25, 26, cooperating with fixed contacts 27, 28 and the latter a contact 39 co-operating with a fixed contact 40. An actuator 35 biased counter-clockwise by a leaf spring 21 is also carried by the frame 20 and forms an abutment for dead-centre springs 47, 36 on the leaf springs 22, 23. A thermal expansion element 50 in the form of a wire is connected between actuator 35 and a terminal 51 on the frame and is so tensioned that when no current is flowing it retains actuator 35 against spring 21 in such a position that contacts 25, 27 and 39, 40 are closed, as shown. Contacts 26, 28 in circuit with a flexible, bimetallic plate 60 forming the shunting device, are open. When the motor is started, the heavy current flowing through the starting and running windings 30, 45, blades 22, 23, and element 50 causes the latter to expand and allow the actuator 35 to swing sufficiently to actuate blade 22 and open the starting winding, by which time the motor will have attained its normal operating speed. At the same time contacts 26, 28 are closed, shunting part of the current through plate 60. If an overload occurs, element 50 expands further and actuates blade 23 to open contacts 39, 40 and stop the motor. This further expansion of element 50 alternatively may be brought about or accelerated by flexing of plate 60 due to abnormal rise in the temperature of the motor, causing contacts 62, 63 to open and the whole of the current to flow through element 50.

Sheet materials composed of adhesivelybonded fibres are made by conveying a fibrous carded web from a carding machine in full width to a lapping machine which deposits the lapped sheet on a conveyer belt moving at an angle to the previous travel of the web, and introducing a rubber or synthetic resin bonding agent into the lapped sheets from one or more spraying jets located outside the area in which lapping takes place, operating in timed relation to the motion of the lapping machine so that the bonding agent is injected between the layers as a small cloud which is applied to the underside of each layer as it falls, and converting the lapped sheet into a consolidated product by pressure. Cresol- or phenol-aldehyde resins may be used as bonding agents, which may be applied in liquid or powdered solid form. Two or more lapping machines may be used, and the lapping machine or machines may be so operated that the fibres in successive sheets lie at right angles to one another. Additional jets may supply other materials such as weighting materials in granular, powder, or fibrous form, hard fibrous waste such as jute or hemp, colouring materials which may be applied to the outer layers only, insulating, electrically conducting, or magnetic particles. The material may be subjected to a water-spray or to water or solvent vapour, prior to consolidation. The edges of the layered material may be treated differently from the centre parts.

Abstract: 1481118 Treating clay ENGLISH CLAYS LOVERING POCHIN & CO Ltd 28 May 1976 [25 April 1975] 17376/75 Heading ClA The rheological properties of a clay are improved by forming a mixture of an aqueous suspension of the clay containing less than 30% by weight clay solids and less than 450 p.p.m. of dissolved silicate (expressed as SiO 2 ), at a pH of 5-9 and a weakly positively charged inorganic hydroxy polymer of aluminuim, there being 0À5-10 mg of Al per gram of clay (dry weight basis). The polymer may be of formula Al(OH) n  X 3-n  where n is 0À5-2À8 and X is Cl, NO 3  or SO 4 , and may be formed in situ by mixing a water-soluble aluminium salt with the clay at a suitable pH where polymer is not precipitated, and adjusting the pH to 5-9 to precipitate the polymer. The clay suspension may be treated as above before, but preferably concurrently with or after, a reductive bleaching process, e.g. as in 520,498. The clay, before or after mixing with the polymer, is preferably subjected to mechanical working to dissipate at least 50 horsepower-hours of energy per long ton of clay (1À3 x 10<SP>5</SP> J/kg) into the plastic mass. The product clay suspension can be dewatered, and the cake dried or reslurried in water. Casts may be made of the clay suspensions.

Title: A process for the purification of an alkali metal hypophosphite solution containing alkali metal phosphite
IPC: C01B25/16
Filed: 1958-06-02
Abstract: The phosphite impurity in aqueous alkali metal hypophosphite solutions is precipitated as an alkaline-earth metal phosphite by the addition of the stoichiometric quantity of an aqueous alkaline-earth metal hypophosphite solution.  Such a solution is prepared from a concentrated (i.e. at least 200 g.p.l.) alkali-metal hypophosphite solution by treatment with a cation exchanger containing alkaline-earth-metal ions, calcium or barium. The preferred cation exchanger is a sulphonated phenol-formaldehyde resin.  In an example such a resin is treated with dilute calcium chloride solution, washed to remove chloride ions, and a concentrated sodium hypophosphite solution is circulated through the column.  Up to 85% of the hypophosphite in the solution is converted to calcium hypophosphite. The column may be regenerated by passing calcium chloride solution through it.

Class 68(2) Water-tight structures for dams, canals &c. are formed by laying a bed of binding materials and then filling the bed by the addition of coarse stone applied layer by layer, each layer being shaken down, e.g. tamped or vibrated, into the binding material before the application of the next layer. The stones form a tightly-packed core resting on the base of binding material which also packs the interstices of the core, the stone carrying the load and the binding material having a sealing effect. This form of structure does not slide and may be used for steep slopes. The binding material may be the usual clays or materials such as a fine grain earthy substance with or without natural or artificial binders.
