Abstract: 1478576 Rolling thermoplastic sheet; pressure-rolling; laminates NIPPON PETROCHEMICALS CO Ltd 29 July 1975 [31 July 1974 2 July 1975] 31641/75 Headings B5B B5A and B5N [Also in Division C3] Films and sheets of thermoplastic resins are orientated by pressure rolling, the film or sheet being passed between a pair of rolls rotating in different directions and at different peripheral speeds. The material is at a temperature below the softening point or the crystalline melting point of the resin. In one embodiment the film or sheet may be taken up at a greater speed than the rollers deliver it; in another the material is maintained in contact with the faster roller for longer than required by passage through the nip. The material may be supplied as a flattened tubular film, which yields a 2-ply laminate, or as several films or sheets, which the pressure-rolling bonds together. In examples the tubular film is made of high density polyethylene, polyvinyl chloride and polypropylene. In other examples 2-ply tubular films comprised of polypropylene/h.d. polyethylene; h.d. polyethylene/ionomer; and polyamide/h.d. polyethylene are extruded, collapsed and pressure-rolled. Laminates exemplified are comprised of layers of h.d. polyethylene laminated to l.d. polyethylene, polypropylene, ionomer or polyamide and polyamide laminated to polypropylene. Single films or sheets exemplified are compression-moulded h.d. polyethylene, polyethylene admixed with glass fibre or calcium carbonate filler, foamed h.d. polyethylene and of h.d. polyethylene mixed with copolymers of styrene/butadiene, styrene/isoprene or ethylene/  propylene and with butyl rubber or polyisobutylene.

As shown in Fig. 2 an independent pump piston 26 is driven by a cam 33 on a half speed shaft, the piston rod being held up to the cam by a spring 34 between a fixed abutment 36 and a collar 35 on the rod. This piston works in a chamber 25 communicating with the power chamber through a port 27. At the end of the compression stroke the pump piston covers this port. A weight 39 is used to balance the weight of the cam. According to the Provisional Specification the supercharging piston may be placed in an extension of the power cylinder and driven from a cam rotated at half speed by sprocket gear. This piston is stationary during the power and exhaust strokes.

In one form, one pair of relatively rotatable prisms is mounted before each eye, form, one pair of relatively rotatable prisms is mounted before each eye, the apical edges of one pair of prisms being capable of being directed upwards and the edges of the other pair being simultaneously directed downwards. In another form, Fig. 1A, one prism 6 is mounted in one eye-piece of a spectacle or lorgnette frame and another 7 in the other eye-piece and the prisms are oppositely directed and coupled by piano wires 10 for contra-rotation. Other forms of wire coupling are described. The prisms 6, 7 may each be mounted in a gear ring and forms of gear coupling are described. As shown in Fig. 2B, the eye-pieces 3 of a pair of spectacle binoculars are mounted on a lever 4 pivoted at 5 so that they can be moved vertically in opposite directions. Alternatively, the objectives may be similarly mounted, or, rotating prisms may be incorporated into spectacle binoculars.

Abstract: 264,143. Canadian Electro Products Co., (Assignees of Matheson, H. W., and Blaikie, K. G.). Jan. 11, 1925, [Convention date]. Hydroxy acid esters are produced in substantially anhydrous condition by the interaction of alcohols on cyanhydrins of ketones or aldehydes in the presence of water and a mineral acid, the water and cyanhydrin being in substantially equimolecular proportions, and the mineral acid being sufficient to combine with the liberated ammonia. Examples are given of the preparation of (1) the ethyl ester of furfuryl glycollic acid by warming together furfuraldehyde cyanhydrin, a solution of hydrogen chloride in ethyl alcohol and the calculated quantity of water; (2) the ethyl ester of a-hydroxy-n-valeric acid, using butylaldehyde cyanhydrin and ethyl alcohol; (3) the ethyl ester of a-hydroxyisobutyric acid, using acetone cyanhydrin and ethyl alcohol; (4) the ethyl ester of mandelic acid, using benzaldehyde cyanhydrin and ethyl alcohol. In these examples water is used in equimolecular proportions with the cyanhydrin, and hydrogen chloride is used in from 1 to 10 per cent in excess of that required to combine with the ammonia formed. Specification 257,907 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the preparation of ethyl lactate using acetaldehyde cyanhydrin and ethyl alcohol.

Abstract: A sintered mass of aluminium nitride is prepared by moulding under superatmospheric pressure into the desired configuration, a mixture of alumina powder, carbon powder and aluminium powder and heating to an elevated temperature, e.g. 1750 DEG  C. in an atmosphere of nitrogen.  By this method, the aluminium powder firstly melts and fills the interstices between the alumina powder and the carbon powder and the reaction of the aluminium, alumina and carbon with nitrogen then takes place as the temperature rises. In the example, 5-30% by wt. of aluminium powder is incorporated into a mixture of alumina powder and carbon powder in a ratio 3:1 by weight.  The product has a small porosity, high density and great mechanical strength.
