Title: Mat and process for its manufacture
IPC: B29C48/30
Filed: 1971-04-19
Abstract: 1308867 Coated sheet materials MITSUBISHI PETROCHEMICAL Co Ltd and U C SANGYO Co Ltd 19 April 1971 [16 March 1970] 24250/71 Heading B2E [Also in Divisions B5 and B6] A mat is produced by injecting a hardenable resin composition by means of a swinging nozzle 4 as shown in Fig. 1 towards and away from a moving sheet 7 so as to cause the composition to adhere to the sheet at successive points and hardening the resin to form loops between the points of adherence. Preferably molten thermoplastics compositions are used for the injection. Resin composition may be injected from a plurality of orifices in the swinging nozzle to provide filamentary loops or it may be injected from one or more slots to provide a corrugated layer of resin adhered to the sheet along parallel lines. The loops of the resin may be cut to provide a pile. The nozzle may be swung between two parallel sheets so that the loops of resin are adhered alternately to respective sheets. If the resin is injected from a slot a corrugated structure is provided. If a row of orifices is used, the product comprises a pair of parallel spaced sheets held together by generally sinusoidal filaments adhered alternately to respective sheets. The sheets may be separated continuously into two mats of the resin loops by means of cutting device 5. Preferably the nozzle is provided immediately upstream of a cooling means for hardening the resin composition e.g. a liquid bath 6 or alternatively cool air. The sheet may be formed of polyvinylchloride, polyethylene, polypropylene or polyurethane or a film, fabric or paper coated with a synthetic resin. The sheet may be prepared by extruding resin and injecting the fibre-forming resin before the extruded sheet has completely solidified. Preferred fibre-forming resins are polyethylene, polypropylene, polyvinylchloride, polyvinylacetate and polyurethane. The sheet or sheets may be made of a fabric coated with an extruded resin. (Fig. 2 not shown). In another embodiment injections are made between one sheet which is adhesive to the resin composition and an endless belt which is non- adhesive to the resin composition so that the free ends of the resulting loop fibres are flattened. (Figs. 4 and 5 not shown). The products may be used for packaging, cushioning or for artificial lawns.

Title: Improvements in and relating to the production of alcohols
Inventor: LEVY NORMAN
IPC: C07C29/04
Filed: 1946-08-16
Abstract: Isopropanol is prepared by reacting water and propylene at elevated pressure and at a temperature in the range of from 250 DEG  to 290 DEG  C., in the presence of an unsupported pelleted catalyst consisting of blue oxide of tungsten of a formula approximating W2O5, prepared by reducing a hydrated tungsten trioxide or ammonium tungstate at elevated temperature. Stoichiometrical quantities of water and propylene may be employed but the tendency to polymer formation is decreased by use of molecular ratios of water to olefine higher than 1 : 1, for example 2.5 : 1 or even up to 20 : 1.  The process is preferably operated as a continuous process, unreacted propylene being re-cycled.  A suitable operating pressure is 250 atmospheres. The catalyst may be prepared by pelleting hydrated tungsten trioxide containing 2 per cent graphite and reducing by means of hydrogen, carbon monoxide, mixtures containing these gases, or a lower aliphatic alcohol; if desired, the pellets may be placed in p  the reaction vessel and first reduced in situ by means of the reactants.  In reducing ammonium paratungstate it is preferred to reduce in a separate step.  In examples illustrating the hydration of propylene, the catalyst is prepared by reducing pelleted hydrated tungsten trioxide containing 2 per cent graphite by means of isopropanol at 250 DEG  C. for three hours.  Specification 622,937 is referred to.  According to the Provisional Specification the catalyst used is one containing the blue oxide of tungsten which has a formula approximating to W2O5 and it is stated that this may be prepared by reducing WO3.ALSO:Blue oxide of tungsten for use as catalyst in the hydration of propylene to isopropanol (see Group IV (b)) is prepared in unsupported pelletted form by reducing ammonium paratungstate or a hydrated tungsten trioxide or, according to the Provisional Specification, WO3, at elevated temperatures.  Hydrogen, carbon monoxide, mixtures containing these gases, lower aliphatic alcohols, or the reactants water and propylene, may be used for the reduction. In an example, powdered hydrated tungsten trioxide containing 2 per cent graphite is pelletted and treated at 250 DEG  C. with isopropanol for three hours and then with water for three hours.

Abstract: 190,539. Rolph, W. M. Sept. 23, 1921. Addition to 171,811. Road-traffic signals on vehicles.-For actuating the signalling apparatus claimed in the parent Specification, a block a, mounted slidably in a casing b, is attached by a wire c to the rack which operates the signalling apparatus. Tubes d, e of different length pass through the block a, and through the tubes pass plungers f, g, which are connected to the s'de brake lever and foot brake pedal respectively. When the plunger g is pulled, the collar e<1> on the tube e moves the block until the tube strikes the adjustable stop g<2>, with the result that the signalling apparatus is actuated; additional movement of the foot pedal merely causes the plunger to move through the tube e and compress the spring j. The plunger f operates the block in a similar manner, but the travel of the block is greater owing to the shorter tube d. A stud l in a slot k in the block is connected to a lever on the steering column by a wire m. When the block a is moved by eitber of the plungers. f, g, it slides past the stud l without affecting the wire m.
