Abstract: A foaming liquid comprising a polyol, a gas generator, an organic polyisocyanate and/or an isocyanate-terminated pre-polymer, and such a weight of polyfunctional organic compound as to be equivalent to 7% of the weight of the polyisocyanate component, is introduced into a mould, the surface of which is at such a temperature below 100 DEG C. (preferably the range 0-70 DEG C.) that the moulded foam produced is covered by a non-cellular surface layer. The polyfunctional compound has at least two active hydrogen atoms at least one of which belongs to an amine group, but does not include primary mono-amines. It may be a polyamine, e.g. methylene-bis-ortho-chloroaniline, or an amino alcohol or amino thiol, e.g. 2-amino-2-methyl-1-propanol. Polyether or polyester polyols may be used. Suitable isocyanate ingredients are toluylene diisocyanate or hexamethylene diisocyanate. The gas generator may be water, monofluorotrichloromethane or methylene chloride. Conventional foaming and cross-linking catalysts, surface-active agents, pigments, colouring agents, antioxidants or anti-UV agents may be incorporated. The mould is preferably made of a silicone elastomer which may be contained in a cradle of steel, aluminium or plastics it may comprise merely a surface on which sheet material may be formed.

Title: Improvements in or relating to Molded Tablets.
IPC: A61J3/06
Filed: 1967-05-29
Abstract: Tablets are prepared by triturating, in the presence of moisture, a powder containing two separate ingredients which react together in the presence of water to produce a gas, with a volatile organic solvent in which at least one constituent of the powder is soluble, moulding the resultant mass into tablet form, and then drying the tablet. Preferred gas-forming ingredients are carbonates or bicarbonates (e.g. of Na, K or Li) with a water-soluble carboxylic acid (e.g. citric, tartaric, maleic, fumaric, succinic, adipic, itaconic or tricarballylic acid). The organic solvent may be ethanol, 2-propanol, chloroform, 1-butanol or acetone, or mixtures of these. The proportion of solvent used is generally about 3 to 40 mls. per 100 gms. of mixed powdered ingredients, and it may contain up to 10%, preferably 0.05 to 3% by weight of water. A pharmaceutical tablet of the invention, containing aspirin and monocalcium phosphate, is prepared. Example 7 describes an effervescent disinfectant tablet containing cetyl pyridinium chloride.

Title: Method of and Apparatus for Making Slotted Strips
IPC: B21C37/26
Filed: 1967-07-06
Abstract: A blank 10 of indefinite length is periodically advanced beneath a reciprocating head 11 carrying cutters 13 which produce transverse slits 4 in at least one of the blank edges, and a stepped cutter 15 which with each cutting stroke of the head 11 (direction F 1 ) cuts a further length of a central slot 18 in the blank, this slot eventually severing the blank into two strips 3 at least one (both, as shown) of which is edge-slotted and intended for use as a heat exchanger tube fin. The stepped cutter 15 has two portions of unequal length, the longer portion 15a having an abutment face 15c. When the head 11 is in the raised position shown, after the cutting stroke, the blank is advanced (direction F) until the leading edge of the centre slot 18 abuts the face 15c of the cutter 15. Thereafter the head 11 descends to cut further slots 4 and a further portion of the slot 18. The blank rests upon a matrix 12 having openings 16, 17 therein to facilitate ejection of scrap.

Title: Magnetic Switch
IPC: H01H36/00
Filed: 1968-02-17
Abstract: A thermally responsive switch has blade contacts, one of which carries magnetic material influenced by two permanent magnets and one at least of the magnets is moved by a temperature-responsive member. The latter is shown in Fig. 1 as a bimetal spiral 11 having a permanent magnet 12 at its end adjacent a sealed contact unit 13 which has three contact blades 16, 17, 21 of which the blade 21 is provided with a magnetic armature body 23. A second permanent magnet 14 normally attracts the body 23 to hold contact points 19, 22 closed until the bimetal 11 moves the magnet 12 across a dash line shown in Fig. 1 so that the magnet 12 is snaped against the glass contact envelope 20 and contact points 19, 22 are opened at the same time as contact points 18, 22 are closed. The body 23 may extend along the blade 21 a greater distance on the side adjacent the first magnet 12 so as to permit a greater degree of bending in the other direction and ensure adequate contact pressure in the position shown. The lower ends of the contact blades (Fig. 4) are clamped together, with interleaved insulators 30, 31, by the bent over edges of the blade 17 and are located on an insulatng plug 33. The magnet 12 may have oppositely poled layers as shown in Fig. 5 and the bimetal layer 36 may be of ferromagnetic material. The second magnet may be movable with the first by means of an extension of the bimetal (Figs. 6 and 7, not shown).

Patent ES-421648-A1 (ES)
Title: High speed printing system with heated roll fuser
IPC: B65H37/04
Filed: 1973-12-20
Abstract: Thermoplastic powder images delivered in succession from the transfer station of a copy machine or the equivalent station of another electrostatic printer at a high rate of speed are fixed to a support sheet by heat and pressure in a substantially slower moving fusing roll couple. This differential speed enables the operation of the fusing roll couple at lower temperatures and pressures to make practical the use of an internally heated fusing roll having a deformable surface. The speed of the fusing roll couple is perferably selected to substantially eliminate the space between successively delivered copies such that the rolls of the roll couple need not be separated between successive copies. A conveyor that transports copies to the roll couple is preferably driven with a programmed speed to match the speed at which a copy is generated and to alternately match the slower speed of the fusing roll couple as the copy is introduced thereto.

Filed: 1974-06-28
Abstract: A hairdressing device comprises an elongate circular cross-section cylindrical body having a relatively small diameter adapted to the size of a hair curl, and a gripping handle extending from one end of the body. A first rectilinear row of comb teeth extends radially from the body, and second and third rectilinear rows of comb teeth extend from the body in opposite sides of the first row and spaced symmetrically relative to the first row. A relatively thin pliers or pressure member is articulated to the body adjacent the handle, and has an operating portion adjacent the handle and an active portion extending in alignment with the first row of comb teeth and movable toward the body to press the hair against the body. The active portion of the pliers or pressure member has an elongated slot therein through which the comb teeth of the first row extend when the active portion is substantially engaged with the body. The body is heated uniformly throughout its length, for example by electrical heating elements or by a stream of hot air and the comb teeth are also heatable. By virtue of the provision of the three rows of teeth, with the first row extending through the slot in the active portion of the pliers or pessure member, the device may be used equally as a heated hair curler or as a heated comb.

Title: Miniature solenoid valve
IPC: F16K31/08
Filed: 1976-01-05
Abstract: A solenoid valve is provided for controlling fluid communication in a passage defined between a first and a second orifices. A valve seat is defined in the passage and a valve member is adapted to be urged into contact with the valve seat to interrupt fluid communication between the first and second orifices. A coil and a fixed core control movement of the valve member in response to energization of the coil. The valve member is attached to a magnetized rod which is coaxial with the core.
