Title: Improvements in or relating to heat generating composition and package, method of producing the same, and method of waving hair with the heat generating composition and package
IPC: C09K5/18
Filed: 1939-05-31
Abstract: 531,250. Heating by chemical action. BRUCE, Inc., L. R. May 31, 1939, No. 16032. Convention date, June 25, 1938. Drawings to Specification. [Class 64 (ii)] A chemical heating composition suitable for use in a hair-waving pad consists of a mercurous salt, a nitrate, and aluminium or a metal above aluminium in the electro-motive series. The composition is moistened preferably with a water-soluble ammonium compound. The heat is generated after an initial delay sufficient to enable the pad to be placed on the hair. The composition is placed in a container of paper, cloth or other permeable material. The mercurous salt may be water-soluble or insoluble, inorganic or organic, e.g. the nitrate, bromide, iodide, acetate, palmitate, or preferably the chloride. Magnesium or aluminium may be used as the metal, in sheet or powder form, or preferably as flakes, fragments or particles. The proportions may be metal 1-50 parts, mercurous salt 0.5-5 parts. The solution may contain ammonia or an ammonium compound liberating ammonia on hydrolysis, or an amine, or an organic or inorganic reducing compound. Heat is generated only slightly for 0.5-4 minutes, and then rapidly within a few seconds. The initial period is extended by adding ammonium, potassium, barium, or preferably sodium nitrate. Other substances having a similar, but also a diluting action, include sodium citrate, aniline sulphate, trimethyl ammonium sulphate, sodium chloride, sodium sulphate, and magnesium sulphate. Insoluble fillers such as silica, activated silica or alumina, or barium palmitate may also be added. The quantity of nitrate used may be 0.25-5 times the weight of the metal. Ammonia derivatives which may be used include ammonium carbonate and borate; aliphatic amines include diethyl amine, ethylene diamine, mono-, di-, and triethanol amine, mono-, di-, and tripropanol amine; aromatic amines include aniline and derivatives, naphthylamine, and derivatives; heterocyclic amines include morpholine, piperidine, quinoline and aminoquinoline. Reducing compounds which may be used include stannous chloride, sodium stannite, phosphorous acid and its salts, formic acid and its salts, hydroquinone, pyrogallol, and reducing sugars. The concentration of these compounds may be 1-30 per cent. The Specification as open to inspection under Sect 91 refers also to the use of a zinc-copper couple in place of the metals in the composition. This subject-matter does not appear in the Specification as accepted.

Title: Wiring harness disc player
IPC: H01B7/08
Filed: 1973-04-04
Abstract: 1458214 Wiring harness RISTS WIRES & CABLES Ltd 15 March 1974 [4 April 1973] 16065/73 Heading H2C A wiring harness comprises a number of leads 11, each having a conductive core and a thermoplastic sheath, a first flexible elongate thermoplastic backing strip 15, partly overlapping and at an angle to, a second flexible elongate thermoplastic backing strip 16, a first length 12 and a second length 13 of the said leads 11, being fused to the strips 15 and 16 respectively, the leads being bent to form curved portions 14 adjacent the overlapping portions 15a and 16a of the backing strips, so as to extend from the first backing strip 15 to the second one 16. The thermoplastic material is preferably PVC. In a method of manufacture the leads 11 are placed on a platform in the required configuration and the backing strip 15 is dispensed from a continuous reel of tape, the mutually presented surfaces being heated so that fusion takes place on contact. The tape is severed beyond the curved portion 14 of the leads, which are then relocated so that the second length 13 is on the platform. The second backing strip 16 is then fused to the second length 13, the strip 16 being allowed to overlap and fused to the region 15a of the first backing strip 15. In a modification the apparatus is capable of depositing the backing strips in two angularly spaced linear paths obviating the need for relocation of the leads. In a further modification the curved portion 14 of the leads are not fused to either backing strip but secured in the desired configuration by external means during manufacture of the harness. Radio frequency welding apparatus could also be used to fuse the sheaths of the leads to the backing strip but in this case other means such as adhesive or a separate fusing operation is used to join the backing strips.

Title: Improvements in and relating to concrete block buildings
IPC: E04B2/42
Filed: 1920-06-16
Abstract: 168,446. Griffiths, W., and Griffiths, W. W. R. F. June 16, 1920. Blocks, special shapes of.-A composite building-block having a body portion composed of wood chippings mixed with parian or like cement is formed with webs 8, Fig. 5, and spaces 9, the inside face 3 of the block being coated with smooth cement and the outside face 22 with rough weatherproof cement. The central web 8 is formed with a hole 12 and the ends of the block with recesses 14, thus enabling successive courses of a wall with broken joints to be firmly secured together by pouring in liquid cement so as to form continuous vertical columns. Recesses 20 are formed round all edges of the faces 3, 22, thus enabling the joints on the inside and outside of a wall to be finished by covering the faces of the joints with a board &c. and pouring in liquid cement. When used for corners of buildings, the blocks are shaped as shown in Fig. 9. In order to construct the block, a portion, Fig. 4, is first formed by means of a mould, Fig. 2, which is open at the top and the bottom and has laterally-removable cores 7, 11. The mould is placed on a sheet of glass &c. and a layer of fine cement is run in, and the portion of the block is then completed by adding a mixture of wood chippings and parian or like cement. The portion of the block thus formed is pressed downwards into a secondary mould 21, Fig. 5, into which has been poured a layer of weather-proof cement followed by a layer of very plastic concrete, which flows over projections 17 and thus causes the two separately moulded parts of the block to be firmly locked together. Specification 146,581 is referred to.

Abstract: 1,012,772. Aerials. BRITISH BROADCASTING CORPORATION. March 20, 1964 [April 26, 1963], No. 16551/63. Heading H4A. A high frequency aerial comprises a cylindrical shell 10 of electrically conducting material having on or adjacent to its outer surface a plurality of aerial elements 12 or groups of elements arranged in a number of tiers the individual elements or each group of elements being so constituted as to radiate tangentially with respect to the shell substantially in one direction only over a sector whose angular width is equal to the angle over which radiation is to take place divided by the number of elements in a tier. In the arrangement shown the cylindrical shell 10 is mounted round a lattice mast 11 with its axis vertical and the elements 12 are unipoles each insulated from the shell and each provided with a director 13 and a reflector 14 or reflecting screen so that each radiates in one direction only over a sector whose angular width (to half field strength points) is 90 degrees to give a uniform horizontal radiation pattern round the shell. Phase shift is introduced in the signals fed to the elements 12 and in order to maintain symmetry, identical phase differences are introduced between all the groups of elements in each tier. When the elements have an insufficient back to front ratio the groups of elements in alternate tiers may be displaced by #/4 measured circumferentially round the surface of the shell (Fig. 1, not shown), the tiers being driven in phase quadrature. The shell 10 may be ellipsoidal, rectangular or diamond shaped, it may also be continuous as shown or perforated, in which case such perforations may be designed to shape or modify the radiation pattern; such a perforated shell may constitute the slotted cylindrical aerial element of another aerial system.

Title: Improvements in or relating to pigments
Inventor: MUSGRAVE CLIFFORD
IPC: C09B67/20
Filed: 1960-05-11
Abstract: A method of making a pigment master-batch comprises mixing a stabilized dispersion of a polyolefine in water with an aqueous mass of pigment, coagulating the mixture, removing the aqueous phase from the coagulum and drying and preferably pulverizing the solid so obtained.  The polyolefine may be polyethylene or polypropylene, advantageously of low molecular weight, and may be stabilized by anionic, cationic or non-ionic surface-active agents.  The pigment may be organic or inorganic, should be insoluble in the polymer and should be finely subdivided. Coagulation may be carried out using free acid, or by adding salts such as sodium chloride, ammonium chloride, potassium hydrogen sulphate, di-sodium hydrogen phosphate, potassium hydrogen phthalate or potassium dihydrogen phosphate and then bringing the mixture to the boil.  If an acid or acid salt is used it is only necessary to add the salt in aqueous solution to pH 4,5, whereas if a neutral salt is used, preferably 100% w/w (calculated on pigment) is added.  At this stage materials such as finely-divided calcium carbonate, pale American rosin or cresol/formaldehyde resin may be added to improve the texture of the pigment.  The pigment powder may be added to a polyolefine such as polyethylene or polypropylene in an amount up to 10% at a temperature between 150 DEG  and 250 DEG C. on conventional equipment.

Abstract: 998,578. Disc brakes. LAMBERT BRAKE CORPORATION. May 1, 1962, No. 16664/62. Heading F2E. A multiple disc friction device, e.g. a brake, having axially aligned friction discs adapted to be urged together has means for circulating cooling fluid through passageways in the disc pack between a space surrounding the disc pack and an interior space, the passageways being formed by a set of radially-spaced annular grooves formed between lands on a first group of discs, the grooves being concentric to one another but eccentric to the axis of the discs, chordally arranged grooves in the same group of discs arranged to intersect all but the innermost lands and to connect the annular grooves to the outer periphery of the discs, and radially arranged slots in the same group of discs extending from their outer peripheries towards and terminating short of the innermost lands. As shown, the first group of discs are rotor discs 36, each comprising a plate 68 with linings 72 having annular grooves 78, the axis A of which is eccentric to the axis B of the discs and chordally arranged grooves 82 intersecting the grooves 78 and intermediate lands 80. Slots 74 pass through both the plate 68 and the linings 72 and extend towards but terminate short of the innermost land 80, intersecting the chordally arranged grooves 82 as shown. Additional grooves 84, 86 in the linings 72 extend between the outer and inner peripheries of the discs 36 and communicate with the grooves 82. The remaining discs forming a second group are stator discs and have sets of slots 64, 66 extending inwardly and outwardly from the outer and inner peripheries of the discs, respectively. The stator discs 34 have pairs of ears 38, 40 engaging guide pins 42 arranged in a two-part stator housing 20, 22 secured to a flange 18 on the axle casing 16 of a vehicle. The plates 68 of the rotor discs 36 are recessed at their inner peripheries for engagement with splines 46 of a rotor 26 which is secured to the vehicle wheel 12 by a flange 28. The disc pack is compressed to apply the brake by the admission of pressure fluid to an annular cylinder 56 in the casing 20, an annular piston 58 in the cylinder acting on an annular pressure plate 50 guided by ears 54 on the pins 42. Release is effected by springs 62. Seals 30, 32 are provided to close off the interior space 94 so that cooling fluid supplied by a pump can be circulated via inlet 88 to the exterior space 92 from which, when the brake is applied, it can only pass to the interior space 94 via the passageways in the brake discs. The cooling liquid is returned to the pump via outlet 90. Owing to the eccentricity of the lands 80 on the rotor discs a wiping action occurs during braking which is said to keep the discs clean and prevent uneven wear.
