Title: Improvements in or relating to waving and unwaving hair
Filed: 1956-06-19
Abstract: A hair-waving paste comprises a dispersion of a water-soluble alkaline borohydride in a water-soluble, easily fusible, synthetic wax which is inert to the borohydride, and a buffering agent. The composition may also include an agent which swells the fibre or assists the borohydride to penetrate the fibre.  The borohydride is one which gives an alkaline reaction in aqueous solution and may be sodium, potassium, lithium, ammonium or an organic borohydride.  The wax may be a condensate of an alkylene oxide, a polyoxyalkyl derivative of a higher fatty alcohol or a sulphate of a higher fatty alcohol.  The buffering compound may be boric acid, sodium carbonate, sodium bicarbonate, ammonium hydrogen phosphate, potassium hydrogen phosphate, glycine or alanine.  Swelling or other assistants specified are urea, thiourea, formamide, primary alcohols, glycols and polyglycols. In aqueous solution the composition may have a pH of 7 to 12. The hair may be moistened with the aqueous solution, wound in curlers and, after a period during which the hair may be heated, rinsed with a solution of lactic, citric or tartaric acid.  In examples, the aqueous treating compositions comprise: (1) sodium borohydride, a polyethylene glycol wax, sodium borate, thiourea and ethanol; (3) sodium borohydride, sodium hydrogen phosphate, caustic soda, thiourea and ethyl alcohol.  Specification 828,208 is referred to.

Abstract: 1,267,804. Steering industrial trucks; suspending single wheels. LANSING BAGNALL Ltd. 23 April, 1969 [23 April, 1968], No. 19030/68. Headings B7D and B7H. An industrial truck has two pairs of wheels 1, 3 and 2, 4, means 76 for adjusting each wheel individually about a vertical axis whereby the truck may be driven forwards or sideways or rotated and steering mechanism comprising a first linkage 19 connecting the wheels 1, 3 and a second linkage 28 connecting the wheels 2, 4 and a member 42 connectible between the linkages by two alternative connections 44, 45, the connection 44 causing all the wheels to be steered in the same sense and the connection 45 causing the wheels 1, 3 to be steered in the opposite sense to the wheels 2, 4. The steering is controlled through a steering box 13 connected by a link 12 to a bell crank lever 15, which is connected to the linkage 19 by a link 18 and to the linkage 28 by the member 42, a selected one of the connections 44, 45, which comprise pins each carried by the member 42 and spring-urged downwards into engagement with a hole in a centrally pivoted plate 37, and by the plate 37 and a link 27. Each pin is raised by the supply of hydraulic fluid through a passage (56) to act on a narrow annular shoulder (58) of the pin. Engagement of both pins together locks the steering mechanism as when the wheels are pivoted through 90 degrees to change from forward to sideways movement by a means 76. Each means 76 comprises a cylinder 77 containing a piston 78 with rack teeth 79 engaged by a pinion 80 on a vertical shaft which is splined to the support of the associated wheel. Microswitches are operated by the means to stop the wheels in the limit positions and when the wheels are stopped in their intermediate positions for rotation of the vehicle, the electric driving motor of wheel 2 only is reversed automatically. The mountings 64 of the wheels 1 and 2 only are suspended on parallel links 65, 66 and sprung by resilient blocks 69, the links 65 being interconnected by a load equalizing link 67.

Abstract: 632,730. Mixing-machines. MASTERS, E. July 21, 1947, No. 19466. [Class 86] [Also in Group XXX] Apparatus for mixing and bagging cattle food comprises a trough containing a driven shaft from which extend arms for mixing the food in the trough. A worm conveyer operates beneath the trough and is adapted to be shut off from the trough or put into communication with it by means of slidable doors. An elevator leads from the delivery end of the conveyer for elevating the material in a duct and discharging it through the mouth of a shoot. As shown the food within the trough 1 which is supported by a framework is mixed by arms 3 rotating on a shaft 2. The base of the trough has horizontal slidable doors 4 by displacing which food in the trough can pass into a compartment 6. The compartment contains a worm conveyer 7 which feeds the food to the lower end of an elevator 8 having lifting buckets 16 operating in an inclined duct 17. The upper end of the duct has a mouth portion 21 of a shoot divided into two separate outlets by fixed blades 23, which direct the food into bags according to the position of the pivoted plate 25. The worm conveyer 7 is driven from an extension of the shaft 2 through bevel gears 11, 12, belt 14 and electric motor 13. The shaft 2 and conveyer are coupled by a chain drive 15. The elevator 8 may be driven from the shaft 2 through gearing or by a belt 20 and pulleys 18 and 19.

[Class 103 (i)] In an internally expanding brake of the " non- servo type, the anchor 26 has adjusting members 24, 28 screwed into opposite sides thereof, the convexly curved ends of the shoes abutting on the members 24, 28 and on the spreader 56, 58 in such manner that they are free to slide to accommodate themselves to the drum. In this way, adjustment of the shoes to compensate for wear is effected by the members 24, 28 alone, the centring being allowed for by the sliding mounting. The release springs 34, 42 are deflected under lugs 46, 48 to keep the shoes frictionally engaged with ledges 44 whereby they are maintained in correct position relatively to the drum. The lug 48 is on a plate 50 secured to a stop member 40 on which the ends of the shoes rest when the brake is released. The spreader is a lever 54 which straddles the stop 40 and has lugs 56, 58 between the shoe ends. The lever is actuated by a cable 52. A construction modified for application to a vehicle propeller shaft, and used primarily as a parking brake, is described. The cable 52 is replaced by a bell crank and a spring-returned rod.

Title: Improvements in the production of coating materials and moulding masses
IPC: C04B28/00
Filed: 1937-07-14
Abstract: Rapidly drying, soap-free, coating or mouldable materials are prepared by mixing one or more acid-soluble metal oxides with an aqueous solution of one or more water-soluble fluosilicates, so as to react therewith, and allowing the reaction mixture to set hard. Suitable fluosilicates are those of aluminium and zinc. Sodium fluosilicate alone is unsuitable, on account of its comparatively low solubility in water, but it may be added together with the more readily soluble fluosilicates.  Fillers, acid salts, and colouring materials may be added.  According to examples: (1) magnesite and zinc oxide are mixed together, and the mixture treated with an aqueous solution of aluminium fluosilicate; (2) magnesite, zinc oxide, talc, quartz powder, feldspar and red iron oxide are mixed together and treated with an aqueous solution of potassium bioxalate, sodium bisulphate, sodium fluosilicate and zinc fluosilicate. According to the Specification as open to inspection under Sect. 91, fluosilicic acid itself may be used instead of an aqueous solution of a water-soluble fluosilicate, while cadmium oxide, magnesium oxide, the hydroxides of cadmium, magnesium, copper, iron, zinc and chromium, magnesium fluosilicate, sodium acid fluoride and fluorspar are specified as ingredients.  This subject-matter does not appear in the Specification as accepted.ALSO:Rapidly drying, soap-free, coating or mouldable materials are prepared by mixing one or more acid-soluble metal oxides with an aqueous solution of one or more water-soluble fluosilicates, so as to react therewith, and allowing the reaction mixture to set hard.
