Abstract: 135,564. Smith, H., and Paine, M. H. Nov. 22, 1918. Two-stroke-cycle engines; driving- gear; cylinders, passages of; pumps.- Cylinders in which air charges are compressed in pump spaces remote from the combustion chambers are arranged parallel to a central driving- shaft carrying an actuating cam. The engine shown in Fig. 1 has eight cylinders on each side of a driving-cam 5 having a path constructed so that five complete cycles occur in each cylinder every revolution, and, preferably, so that the pistons dwell at the ends of their power strokes. The cylinders on the two sides of the cam are staggered. Fuel pumps 14, which may compress a rich mixture of air and liquid fuel, are arranged coaxially with the cylinders, each pump-rod 31<a> being connected to the piston-rod 8 of a co-axial main piston. The pumps have depending cylinder heads 29 over which reciprocate sleeves 30 carried by the pistons 31. Pistons 33 in each sleeve register with inlet ports 34, and afterwards with delivery ports 35, which open into the explosion cylinders through ports adjacent the heads 15. The pump spaces of the explosion cylinders 1, 2 have air admission ports 25 which are uncovered by the main pistons. After compression, the air is transferred to a combustion space through a passage 22 and a port 21 in a sleeve having a port 23, which registers, with an exhaust port 24, and a further port which coincides with a fuel admission orifice. Pipes 37 discharge exhaust gases tangentially into a common outlet pipe 38. The air and fuel inlet passages are arranged tangentially to their supply pipes. A modified construction of engine is described in which the sleeves on the working pistons are dispensed with.

Title: A method of producing a laminate packaging material
IPC: B29C65/00
Filed: 1966-03-28
Abstract: 1,101,472. Package seams. TETRA PAK A.B. 28 March, 1966 [15 April, 1965], No. 13604/66. Heading B8C. [Also in Divisions B4 and B5] A web suitable for forming into tubular packaging material is made by permanently bonding a coating layer, e.g. of plastics, to a carrier web, e.g. of paper, along two spaced longitudinal zones whilst leaving an unbonded continuous longitudinal zone therebetween and cutting through each of the layers along different continuous longitudinal lines laterally spaced apart in the intermediate unbonded zone, thus splitting the web into two and producing a strip of coating material overlapping the edge of the carrier web. The projecting strip so produced may be lapped over in various ways to produce a sealed seam when the web is formed into a tube (Figs. 5, 8a or 8b, not shown). The material may be produced by extruding a layer, e.g. of polyethylene or polypropylene on to the paper layer and passing them around a chilled roll and co-operating pressure roll, adhesion in a longitudinal zone being avoided either by prior application of a strip of parting agent, or by providing an annular groove in one of the rolls so that they do not press the two layers together in this zone. Preferably vacuum is applied to the grooved roller to ensure non- adhesion. The laminated web is then cut through in the unbonded zone by a double cutting wheel 10, one cutter 11 of which cuts through both layers 1 and 2 whilst the other 12 cuts only through the carrier 1, thus producing a projecting strip of the coating layer. Both. sides of the paper web may be coated, a separate cutter being used to cut through each coating layer at transversely spaced position, the unbonded strip of coating thus freed then being laid back, and a double cutting wheel used to remove the intervening zone of carrier web thus producing two webs coated on both sides and on single projecting strip of coating material along one edge (Figs. 6 and 7, not shown).

Abstract: 730,832. Generating arrangements; systems. depending on two or more sources. BENDIX AVIATION CORPORATION. May 18, 1953 [June 3, 1952], No. 13929/53. Class 38 (4). To ensure that a shunt generator 6, 7 builds up a voltage of correct polarity, the shunt field circuit includes the contacts of an electromagnetic switch 20 which, in its de-energized condition prepares the circuit for "flashing" by an appropriately poled D.C. source. This source may be a battery 39 which normally floats on the bus-bars 10, 11 to be fed by the generator, or may be independent. of the generator. The " flashing" circuit is completed upon closure of a manually controlled switch 33, which also completes the energizing circuit of the coil 34 of the electromagnetic switch. This switch then responds, with a delay which may be artificially increased, and establishes a normal shunt connection for the field 7., A protective resistor 31 limits the "flashing" current in event of failure of switch 20 to respond. The field circuit also includes the usual carbon-pile voltage regulator 17. Machine 6, 7 may be an exciter for, an alternator.
