IPC: F41F1/08
Filed: 1937-01-20
Abstract: 484,235. Automatic guns. WIMMERSPERG, H. Jan. 20, 1937, No. 1673. Convention date, Jan. 22, 1936. [Class 92 (ii)] A double-barrel machine gun has a movable barrel 2, Fig. 1, which is fired at the end of its backward movement and another barrel 3 pre. ferably stationary which is fired when the barrel 2 reaches its forward position, means being also provided to feed the cartridges to the two barrels. Further, a long extension member 2a of the movable barrel 2 guides the cartridges to the moving barrel and engages the striker 8 to fire the cartridge in the other barrel 3. In the form shown in Fig. 1, after the fixed barrel 3 has fired, the tapped gases act on a piston 2g on the barrel 2 to move this barrel rearwards over the cartridge II against the action of a return spring 4. The extension 2a of the barrel 2 is furnished with a notch 2r to lock the tilting breech block 5 and a projection 2k which engages the tilting breech block 9 to unlock it from the notch 1r and move it rearwards to extract and eject the cartridge from the barrel 3. The barrel 2 in its rearward movement loads and locks the breech and fires when the firing pin 6 strikes the rear casing. The barrel 2 then moves forwards the projection 5k unlocking and retaining the breech block 5 and the projection 2k moving the breech block 9 forwards to lock the breech and fire the cartridge I in the barrel 3. The cartridges are fed to the barrels by ordinary box magazines feeding horizontally at the side of the gun. Figs. 3 and 5 show a modification in which the cartridge feed is from a double-row belt 26 formed of hinged metal links. The belt is advanced step by step by feed and retaining pawls on a feed slide 20 which is reciprocated vertically by the engagement of a pin 20z with a groove 2n in the barrel extension 2a. The cartridges II from one row are pushed laterally from the belt to feed the barrel 2 by a spring-controlled lever 17 pivoted at 18 and operated by a link 15 engaged by the barrel extension 2a when it starts to move rearwardly. The barrel 3 is fed by a projection on the breech block 9 which engages directly with the cartridge I in the other row of the belt. To take up recoil and store energy for the return of the barrel 2, a spring buffer 13 is provided in addition to the return spring 4.

Filed: 1940-01-29
Abstract: 557,965. Fuel-injection systems. HINCHCLIFFE, S. Jan. 29, 1940, No. 1749. [Class 7 (iii)] In order to build up fuel pressure at the injection valve before it opens, an accumulator cylinder 1 is provided having a piston 2 larger than the piston 4 attached to the injection valve, a spring 6 being arranged between the two pistons as shown, so that fuel supplied by a pump B and passages 13, 15 moves the piston 2 down until it reaches a stop 1a, after which the pressure of fuel builds up against the piston 4 and opens the valve for the injection. When the pump pressure is relieved, the injection valve is closed, and the accumulator piston 2 rises, expelling oil past a spill valve 14 in the pump. In a modification of the pump, the spill valve is arranged between the pump cylinder and the delivery valve, which has a piston stem displacing fuel back to the pump as the delivery valve closes. In another form of accumulator, a single piston acts both as the accumulator piston and as the valve-opening piston, a lost-motion connection being arranged between the piston and the injection valve. In the form with a closed circuit for the pump, the cut-off valve is positively operated in timed relation to the pump, and is preferably placed adjacent to the injection valve.

Title: Improvements in or relating to the absorption and dissemination of heat in cooling systems
IPC: F01P3/22
Filed: 1944-02-08
Abstract: <PICT:0620388/III/1> In a heat interchanging apparatus comprising a heat exchange unit in which a heat absorbing fluid is continuously fed at boiling temperature by circulating means through a passage or passages, the walls of which are continuously heated, a liquid film of the fluid is continuously maintained over the whole heated surface of the passage or passages by adjusting the relationship of the length and hydraulic radius of the passage or passages and the velocity of fluid flow to the physical properties of the fluid in a specified manner.  If the fluid has components of different p volatility, it is maintained at the boiling temperature of a more volatile component.  In the apparatus shown, for heating and vaporizing petroleum in a refinery topping operation at atmospheric pressure, the preheated crude oil is passed alternately through vapour separators 1, 2, 3 and vertical tube vaporizers 4, 5, 6.  The vapour from the separators 1, 2, 3 and the oil-vapour mixture from the vaporizer 6 are fed to a continuous fractionating column 11.  The bottom stream from column 11 is circulated by a pump 10 through the vaporizer 6 which acts as a boiler.  Pumps 7, 8, 9 circulate the oil through the vaporizers 4, 5, 6.  The oil flows through the tubes of the vaporizers 4, 5, 6 at such a rate that a thin liquid film is continuously maintained over their full heating surfaces. Examples of dimensions are given.  Heat may be transferred from the heat source to the vaporizers by circulation of a boiling fluid, e.g. mercury or a eutectic mixture of diphenyl and diphenyl oxide, preferably heated under conditions of continuous liquid film vaporization.  Continuous liquid film evaporation may also be used in the evaporation of milk, in crystallization, in concentrating dilute solutions, e.g. brines, caustic, acids, wash waters, and waste liquors, and in separating solvents from non-volatile or less volatile substances.
