Abstract: 1,102,469. Perforating. KHARKOVSKY AVIATSIONNY INSTITUT. 1 April, 1966, No. 14473/66. Heading B3W. A method of cutting blanks from moving sheet material comprises passing the material 2 adjacent the mouth of a cavity 3 formed in a housing 4, there being a plug 6 in the cavity to restrict the mouth to an annular opening. An explosive force is created which causes a fluid medium to issue from the gap as an annular jet which cuts the material. An apparatus for performing the method comprises the housing and plug, a barrel 5 having a cartridge chamber 7, a breech block 9, a spring-loaded firing pin 8 and a trigger pin 13. A cartridge is placed in the chamber 7 by removing the breech block 9 and when it is fired the gases produced pass into the cavity 3 and through the annular gap in a jet which cuts the material in 0À0001 secs. In a modification a liquid is pumped into the cavity 3 at a rate which equals the rate at which it escapes through the annular gap, and a piston 15 is inserted in the barrel 5. When the cartridge is fired, the piston moves down, and forces an annular jet of liquid through the gap between the housing and plug to cut the material.

Title: Air-operated guillotine
IPC: B23D15/12
Filed: 1963-04-16
Abstract: 959,270. Shearing. E. G. TELFER. April 16, 1963 [April 13, 1962], No. 14839/63. Heading B3W. A pneumatically operated guillotine in which the moving blade is secured to a frame pivoted on the main frame of the machine has a main air cylinder connecting the blade frame to the main frame, a servo-valve connected to the main air cylinder, an air clamp, and a two-stage pilot valve, the first stage operating the air clamp and the second stage operating the servovalve. The main frame comprises two end plates 11 connected by a front plate which carries the fixed blade 15. The moving blade 23 is mounted on a frame 20 supported in adjustable eccentric bearings 17 on the end plates, and connected by links 26 to crank arms 27 mounted on a rocker shaft 28. The rear edges of the end plates are connected by a pipe 32 which has four pairs of lugs 33, each pair supporting the trunnion of an air cylinder 34. The piston-rod of each cylinder is connected to the second arm 36 of the cranks 27. Each pair of lever arms 36 is connected by a plate which carries a rubber buffer 39 adapted to strike the rear face of the plate 12, whereby the energy released at the final stages of a cut is absorbed. The links 26 have lugs 44 which carry the lower end of heavy return springs 45, the upper ends of which are anchored on the end plates at 46. A treadle 51 operates a pilot air valve 55 which when moved to a first stage position admits air to a hose type clamp 63 and when moved to a second stage position also admits air to a selector valve 82. The selector valve 82 is manually operated and is moved to a position in which it admits air to two, three or four main air cylinders according to the thickness of material to be cut. Air passes through the selector valve 82 to the top of the spool type servo-valves 67 mounted one on each main cylinder and forces the spool 69 down against a spring 75 so that air passes from an inlet 71 to the cylinder 34. When the pilot valve is reversed, the spool 69 is returned by the spring 75 and the cylinder exhausts through a port 73. When the treadle 51 is operated to move the pilot valve to its first stage position, an arm 91 is raised so that a cam 92 on the main rocker shaft can move under a roller 93 and prevent return of the treadle. This ensures that the clamp is operative during a cutting operation. To operate the clamp only the treadle is depressed to the first stage position of the pilot valve and is locked in that position by a hook 97 operated by arm 95.

Abstract: 402,406. Bringing seaplanes on board aircraft carriers. BOUR, E. F., Forest-side, Mauritius. May 26, 1932, No. 14936. [Class 115.] In a device for bringing seaplanes on board aircraft carriers in which a trackway 14 trailed at the stern is tensioned by a resistance device 15, this tension is graduated by adjusting the inclination of a drag blade 36, Fig. 6, hinged at the rear of the resistance device. This is achieved by the hydraulic cylinders connected to the drag blade and mounted either directly on the resistance device or on the ship. In either case the inclination of the drag blade is determined by the setting of a spring controlled valve 41, Fig. 10, interposed in the feed-pipe of the pump operating the hydraulic cylinders, the setting of the valve thus determining the pressure in the cylinders and hence the position of the pistons and through the rope connection 14b the inclination of the drag blade. When mounted on board ship the hydraulic cylinders control the position of a sliding platform 7 carrying the winches on which the ropes connected to the drag blade are wound. A separate roller 4 is provided around which the trackway 13 is wound when inboard. The trackway comprises metal sheets 17, 17a, 17c connected to transverse cross-bars. Alternatively the overlapping ends of transverse sheets are rivetted together. The resistance device may carry buoyancy members.

Filed: 1929-05-13
Abstract: 333,564. Petters, Ltd., and Vaughan, J. M. May 13, 1929. Starting; stopping; turning-gear.- A control apparatus for starting and stopping Diesel and semi-Diesel engines having an air-admission control, a fuel control, an ignition control, and a starting motor comprises a power operated multiple-contact switch, having contacts connected to the controls and to the starting motor and brought into action in sequence and at the desired time intervals. As shown in Fig. 1, the shaft h of the switch is driven by an electric motor g controlled by a two-way switch f operated by hand, ball float, thermostat, clock, or other means. The shaft h carries cam contacts k for engagement with brushes m connected respectively to the switch f, a starting motor b for the engine a, a solenoid c controlling the air-admission valve of the engine and a heater e for ignition at starting. The cam contact k<1> breaks the circuit of the motor g when the switch has completed the cycle necessary to start the engine. The starting motor b may be connected to the contact brushes m directly or through a relay. For stopping the engine, the switch f is moved into its second position and the rotation of the shaft h closes a contact leading to a solenoid d arranged to lift the suction valve of the fuel pump. The multiple-contact switch is preferably turned intermittently by means of a cam wheel o, Fig. 2, having slots r engaged by pins 8 on the final gear wheel t of the reduction gear box. Notches o<1> in the cam wheel correspond to the several angular positions in which the switch is to be retained, and are engaged by a roller p on a lever p<1> controlled by a spring q. When the pin s engages the end of the slot r, the cam wheel o is carried round, the roller p being forced out of its notch, and the cam wheel is then moved forward by a spring u until the roller p engages the next notch.
