IPC: A43D3/02
Filed: 1922-11-01
Abstract: 210,523. British United Shoe Machinery Co., (Fitz-Empire Double Pivot Last Co.). Nov. 1, 2922. Lasts.-In a last of the type comprising a fore part and heel part capable of relative movement to bring the last into extended or collapsed condition, and a bonding member connecting these parts, a yielding pin or fulcrum or a yielding hinge element co-operates with the bonding member to form an impositive lock, the yielding element being distorted as a change is made from one condition towards the other. The pivots 22, 24, Fig. 1, connected by the bonding plate 14 may comprise pins supported at their ends only and bent as the condition of the last is changed. The fulcrum between the two parts of the last may be a slotted tube 34, Fig. 4, or a coil spring. Or the bonding plate 44, Fig. 6, may have a slot with a cam surface 54 which co-operates with a transverse pin 56 supported only at its ends. The resilient pin may be formed as a one piece pin with a central longitudinal slot and protuberances at one end to hold it in position, or of two pieces, each hemispherical in cross-section and arched longitudinally.

Title: Process in the manufacture of composite materials
IPC: B23K20/00
Filed: 1973-06-25
Abstract: 1426476 Making reinforced metal composites UNITED AIRCRAFT CORP 25 June 1973 [10 July 1972] 30055/73 Heading B3A A method of making a plasma sprayed aluminium or aluminium alloy composites reinforced with a plurality of filaments comprises placing at least one composite tape having a plurality of unidirectional filaments embedded in a plasma sprayed matrix between heated platens, pressing the tape or tapes between the platens for 2-40 minutes in air at 7-700 kg./cm.<SP>2</SP> to densify the matrix, the temperature of the platens being below the solidus temperature of the matrix when the pressure is 140- 700 kg./cm.<SP>2</SP> and between solidus and liquidus when the pressure is 7-140 kg./cm.<SP>2</SP>, the temperature, pressure and pressing time being sufficiently high to cause bonding of the matrix to the filaments without degradation. The composite tape may have a foil backing for ease of handling and when a plurality of tapes are stacked together between the platens, the filaments may be uniaxial or laid as cross-plies at various angles. The filaments are selected from the group boron, silicon carbide, silicon carbide coated boron, boron carbide, alumina or carbon. Preferably a stack of aligned tapes is held between the closed platens at a low pressure to allow them to regain their original temperature and then a pressure of 35-140 kg./cm.<SP>2</SP> is applied for bonding to occur in 2-15 minutes. After bonding, the platens are opened, the tapes advanced and the process is repeated. Alternatively a higher bonding pressure of 140- 350 kg./cm.<SP>2</SP> may be used, in which case the platens are below the solidus temperature of the matrix and for economic reasons not more than 25‹ C. below. The tapes should be brought to temperature rapidly to obviate the need for a vacuum or an inert atmosphere and bonding is achieved in a short time at low pressure thereby avoiding fibre degradation and crushing in the case of cross plied composites.

Patent GB-844728-A (GB)
Title: Improvements in or relating to the production of mould-proof food products
IPC: A23B4/12
Filed: 1958-09-22
Abstract: In coating food such as cheese or table-ready meats to render it mould-proof, the food is placed at ground potential in an electrostatic field and antimycotic agent particles such as crystals of sorbic acid are sprayed on to the food through the field from the other end.  According to an example, slices of unoiled (cheddar) cheese and Swiss cheese were conveyed on a belt moving at 18,9 ft./sec. maintained at ground potential and positioned fifteen inches from the belt a charged ring was maintained at 25,000 volts.  Sorbic acid crystals were sprayed by air from a gun placed 21 inches from the belt, through the charged ring and on to the cheese; 960 p.p.m. of sorbic acid was uniformly deposited on the slices which were thereby rendered mould-proof. In a modification, the spray of particles was deflected on to the food.

Abstract: A continuous process for making petroleum cokes comprises contacting coke particles with a fluid petroleum residuum to form a combustion charge and concurrently passing the charge and a combustion-supporting gas into <PICT:0994953/C4-C5/1> a combustion zone 24 under conditions such that the zone remains stationary and only a minor portion of the charge, e.g. 2% to 15% by weight, is burnt, the remaining residuum being coked by heat from the zone.  As shown, coke particles are fed downwardly into a retort 12 and may be preheated by gases delivered to the retort at 17, 18, the residuum, which may be liquid but is preferably vaporized, being delivered to the retort at 20, 21, in amounts of 8% to 25%, preferably 12% to 20%, by weight of the coke. The combustion supporting gas, which may be preheated, is delivered at 22, 23, and may be fluorine, chlorine, or nitrogen dioxide, but is preferably oxygen alone or with an inert gas, e.g. air or an oxygen-superheated steam mixture.  Product coke is led off at 16, smaller coke recycled via lift 17a, and volatiles &c. led off at 27, non-condensibles, e.g. CO, C3H8, being separated at 28 for recycling, if desired, to the retort.  Temperatures of 400 DEG  to 1200 DEG  C., preferably 750 DEG  to 1200 DEG  C., are maintained in the zone 24 by regulating preheat temperatures and coke and gas throughput, and the zone is held stationary by making the pressure in the top of the retort higher than in the zone 24.  It is stated that the coke particles and the residuum may be fed to the retort in the form of a slurry.

Abstract: In a method of waving hair without the use of heat, the tresses of hair are each wrapped in a water-permeable pliable wrapping material carrying a substantially non-volatile water-soluble keratin-reducing composition containing essentially a mercaptan and an alkaline buffering material which is a hydroxy amine of the formula <FORM:0860978/IV(c)/1> in which X is hydrogen or an alkylol radical containing 1-3 carbon atoms, R1 and R11 are hydrogen, alkyl radicals containing 1-3 carbon atoms or alkylol radicals containing 1-3 carbon atoms and R111 is an alkylol radical containing 1-3 carbon atoms, excluding monoethanol amine; the tresses are then each wrapped about a curler and saturated with water so that the keratin-reducing composition is dissolved out of the wrapping material into the tress, the action of the composition on the hair subsequently being neutralized.  The mercaptan may be a mercapto alkanoic acid such as mercapto-acetic acid, mercapto propionic acid, mercapto butyric acid or mercapto caproic acid or a water-soluble salt thereof, e.g. sodium or potassium thioglycolate, monoethanolamine thioglycolate, b -mercapto iso butyric acid, thiohydracrylic acid, b mercapto-n-butyric acid, a -mercapto caproic acid or thiolactic acid, or mixtures thereof, and the sheets of wrapping material preferably carry an amount of mercaptan equivalent to from .003-.020 grams of thioglycolic acid per square inch of sheet.  The amount of alkaline buffering material used is preferably such that, when the composition is in solution and in contact with the hair, the pH value is 8,5-10,0.  The keratin-reducing composition may also contain a water-soluble disulphide of the mercaptan or a water-soluble salt thereof, lanolin, lanolin derivatives, perfumes, wetting agents, dyes, binders and plasticizers.  The water permeable pliable wrapping material may be cloth or paper, preferably cloth made from purified cotton or paper made from purified flax, provided if necessary with a plurality of perforations to increase its water permeability and is preferably 0,005-0,0005 inch thick before impregnation and long enough either to extend the entire length of the hair tresses or only to cover the ends of the hair tresses in the manner of "end wraps." The wrapping material may be impregnated with an aqueous solution of the keratin-reducing composition and dried to a moisture content between 2 and 10% by weight.  The action of the hair of the mercaptan in the keratin-reducing composition may be neutralized by bromates, perborates or hydrogen peroxide or by the action of air alone. U.S.A.
