Title: Improvements in or relating to the manufacture of elastic fabrics
Filed: 1937-01-28
Abstract: 482,683. Elastic fabrics; compound fabrics. SCHWARTZ, F. F., and CHAVANNES, M. A. Jan. 28, 1937, No. 2553. Convention date, Dec. 5, 1936. [Class 140] One surface of an extensible fabric is sprayed with rubber latex, without rendering it non- porous, and while the rubber is capable of being compacted, mechanical pressure is applied along continuous lines, which need not be straight, and may intersect. Two or more fabrics may be coated and united under light pressure before. the application of local pressure. The pressure may be applied by means of an embossed plate or cylinder or if the fabric is embossed in lines prior to the application of the latex, the pressure may be applied by a smooth plate or roller. The rubber deposit may be treated with a solvent, such as benzene, preferably in the form of vapour, before the application of local pressure. Specification 482,679 is referred to.

Title: Improvements in automatic loading firearms having a breechblock temporarily held in locked position by a sliding system
IPC: F41A3/70
Filed: 1951-02-01
Abstract: 678,425. Automatic firearms. BREVETS AERO-MECANIQUES SOC. ANON. Feb. 1, 1951. [Feb. 18, 1950] No. 2559/51. Class 92 (ii). Relates to automatic firearms of the kind in which the breech block is temporarily locked by a sliding system which itself carries at least one relatively sliding mass adapted to prevent rebound of the system, and is characterized in that the sliding mass is so arranged that it undergoes most of the friction exerted between the breech casing and the system during at least the end.of the frontward movement of the system. In the construction shown, the side bars 6 of a gun having a Hispano action, each receive a spring-controlled sliding mass 1 which is guided on its bar by a mortise and tenon arrangement as seen in Fig. 2. Both the side and the upper faces of each mass frictionally engage at 11a, 11b, with the inner wall of the breech casing 2. Such frictional contact may take place only during that part of the stroke when the bars and masses are moving forwards together, the frictional breaking action on the masses ceasing when they move forwards alone. A dovetail joint 13 keeps the mass 11 applied against the bar 6 when the bar is removed from the firearm. In modifications, elastic plates are used to bear against the breech casing or against the mass 6, or the mass 6 may be made, over a portion of its length, in two parts which are urged apart by springs so that one part is made to bear on the breech casing. Specification 598,227 is referred to.

Title: Improvements in or relating to rotary combustion engines
IPC: F01C21/08
Filed: 1935-01-26
Abstract: 430,715. Rotary internal-combustion engines. HANNOVERSCHE MOTOREN GES., 292, Podbielskistrasse, Hanover, Germany. Jan. 26, 1935, Nos. 2631 and 2632. Convention dates, Jan. 27, 1934. [Class 110 (ii)] The engine operates on a six-stroke cycle, being the four strokes of an Otto cycle and a suction and discharge of scavenging and cooling air. The invention is applicable to outwardly-sliding vane and axially-sliding vane engines. In Fig. 1 fuel enters a port 17, is fired at 21 by one of a number of plugs 16, and the gases are exhausted through a port 18. Scavenging air enters and leaves by way of ports 19, 20. Pairs of vanes are connected by rods 11 which slide in liquid-tight bushes in a centre section 5 which contains oil under pressure. The latter enters ports in the rods 11 and is fed outwards to the vanes which are built up of a number of plates arranged as shown in Fig. 5. The oil lubricates and seals the vanes. Segments 2, 3 of the rotor are attached to end plates. Air entering the port 19 may pass over the casing sections II-IV, prior or subsequent to, scavenging the working chambers. The casing wall between the parts A, B is shaped to provide adiabatic expansion of the gases between the bore and the rotor surface. In a modified arrangement, pairs of vanes are not connected, but extend into a central chamber containing fluid under pressure which presses the vanes outwards. Fig. 8 shows another construction in which a ring piston 22 has vanes 23 guided between inner and outer casing walls 1<a>, 1, thus forming working compartments inside and outside the piston. A further arrangement describes axially sliding vanes in a rotor, between walls curved as in the earlier examples. More than three compartments may be incorporated in an engine. The engine may be modified to operate on the Diesel cycle. If the number of working compartments is other than three, or a multiple of three, valves must be supplied between strokes.

Patent GB-657279-A (GB)
Title: Improvements in sheet delivery mechanism for printing and other machines
IPC: B41F21/10
Filed: 1949-02-04
Abstract: 657,279. Sheet-delivery apparatus. MIEHLE PRINTING PRESS & MANUFACTURING CO. Feb. 4, 1949, No. 3092. Convention date, March 5, 1948. [Class 100 (i)] In the transfer of sheets from a rotary carrier to delivery mechanism, each provided with a series of co-operating sheet-gripping elements and the elements of the two series being interspaced, a method of controlling the sheets during their transfer comprises the steps of partly releasing the sheet from the carrier gripping elements so that contact with the leading edge of the sheet is maintained while bringing the delivery mechanism gripping elements into contact with said edge so as to flex it between disaligned parts of the elements of the respective series contacting with it, maintaining this flared condition during the entire period of transfer, and causing the delivery mechanism gripping elements to co-operate for gripping said edge to deliver the sheet. A sheet is transferred from a printing cylinder 10, Figs. 2, 4 and 5, to a chain conveyer 16, the gripping elements consisting of grippers 13 and pads 39 on the cylinder and grippers 14 and pads 40 on the delivery mechanism. The trailing edge of the sheet is stripped from the cylinder and guided by a blade 24 and supported by a guard 25 which can be raised by a crank 29 to give access for inspection to the form rollers, forms and impression cylinders. The chain sprockets 18 are driven by a gear 35 on the cylinder through an anti-backlash gear 30 comprising a drive section 31 rigidly mounted on the sprocket shaft 19 and a floating section 32 rotatable on the shaft and movable relative to the section 31 to a small amount limited by pins 33 on the section 31 riding in slots 34 in the section 32. When the cylinder is in its lowered or printing position the gears are slightly separated and to ensure firm engagement thereof a spring 36 urges the section 32 anticlockwise so as to cause its teeth to project in front of those on the section 31, which in effect widens the teeth. A cam 23 on the shaft 19 acts on a roller 22 on an arm 21 carried by the gripper shaft 15 to operate the grippers 14, and the grippers 13 are operated by a cam on the cylinder. In the lower position of the cylinder, the edge of the sheet is flexed during transfer between the grippers 13, 14, and in the upper position between the pads 39, 40 until it is gripped, in both cases, between the grippers 14 and pads 40. As it becomes flexed, it is released from being gripped between the grippers 13 and pads 39 by slight opening of the grippers 13. The speed of the conveyer is constant and less than that of the cylinder, the grippers 14 and pads 40 being accelerated at the point of transfer. The above method of transfer can be used for a two-colour press having two impression cylinders and a transfer cylinder, the sheets being delivered from the second impression cylinder in printing position to the conveyer.
