Abstract: 1,171,767. Two-stroke engines. B. HOOPER and J.E. FAVILL. March 3, 1967 [Dec.4, 1965], No.51564/65. Heading F1B. The pump part 15 of a stepped-piston twostroke engine forces the charge on the upstroke through port 32, controlled by a recess in the piston, into a receiver 30. Near the bottom of the piston downstroke, the top of the working part 14 of the piston re-opens port 32 to allow the charge to flow from the receiver 30 into the cylinder for scavenging and charging. The inlet passage 21 of the pump portion 15 is connected to a carburetter and contains reed valves 22 or a cam-actuated valve. The receiver 30 may comprise more than one chamber and the total volume of the receiver is at least three times the pump swept volume. In a multi-cylinder engine one receiver space 30 may serve two adjacent cylinders.

When the die parts 13, 14 are in contact they present a continuous cutting edge 16 surrounding a square aperture 17 having an arcuate intrusion provided by a part spherical pocket (18) in each corner, Fig. 1 (not shown). A metal sheet is positioned on top of the die and a pierce-nut having a pilot portion corresponding in size to the cutting edge 16 is forced into the sheet so that the pilot portion punches through it and enters the die. The exterior of the die parts 13, 14 is frusto-conical, so that as the nut and sheet are raised after securing, the die parts are lifted thereby enabling them to be moved apart. On the next operation they are forced downwardly and brought together again.

Abstract: 1,243,355. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 Nov., 1968 [4 Nov., 1967 (2)], No. 51836/68. Heading H1K. The NPN transistor shown is produced with many others in a semi-conductor wafer. The P-type region 7 forms part of a grid produced simultaneously with the base region 3 by a common diffusion step. The peripheral N-type zone 6 forms part of a grid produced simultaneously with the emitter region 5 by a common diffusion step. The zone 6 is of higher conductivity than the collector region 1 and acts as a stopper for any inversion layer extending from +he base region towards the edge of the device. The transistor is separated from its parent wafer by division along the grid lines; these lines were used for process control during manufacture. The method of manufacture is varied in dependence on the use of positive or negative photo-resists during the various process steps.

Abstract: 1,225,078. Partitions. G. ARNAUD. 10 Nov., 1969 [8 Nov., 1968], No. 55003/69. Headings B5A and B5N. Partitions including a plurality of reinforcing elements are produced by a process comprising positioning the reinforcing elements in relative predetermined positions, interlacing a band of glass fibre material between the reinforcing elements, placing a shuttering about the reinforcing elements, providing an expandible resin foam, non-adherent to the shuttering, in the shuttering, allowing the resin to expand and envelop the reinforcing elements and removing the partition thus formed from the shuttering. In Fig. 4 a band of laminated or non-laminated unidirectional fabric 11 composed of longitudinal glass fibres joined together by transversal glass fibres sufficient only to ensure the transversal joint of the longitudinal fibres, is interlaced between reinforcing elements 10 and a shuttering of plastic sheets 12, e.g. of polyvinyl chloride, which may be reinforced by having glued thereto battens of wood which are situated outwardly of the partition and transversely of the reinforcing elements, is placed about the elements 10, by suitable fastening means starting at the lower part of the wall preferably to a height of 40 cm. The filling of the polyurethane P is then carried out up to the level of the highest part of the shuttering and then a further section of shuttering placed and further polyurethane added. Since the polyurethane is obtained by a mixture of two products, a mixing gun may be used to fill the partition. The shuttering may then be removed and the surface covered with a layer of an accelerator to increase the hardening rate of the resin. The reinforcing elements 10 may be produced by a process comprising indicating the desired shape of the reinforcing element on a flat surface, fixing laths on the surface according to the desired shape, providing an expandible resin foam, e.g. polyurethane, non-adherent to the surface, in the space between the laths, providing a surface non-adherent to the foam on the laths, allowing the resin to expand and removing the laths and expanded foam forming the reinforcing elements from the surface. In producing the reinforcing elements the walls of the frame may be covered with a glass fibre mat prior to pouring in the expandible resin foam, and after pouring in the expandible resin foam the frame may be covered with a glass fibre mat. The partitions may be used for construction units, sound-proof and heat-proof walls, packaging and shells for light boats.
