Title: Improvements in or relating to fire extinguishing apparatus
IPC: A62C13/00
Filed: 1942-10-27
Abstract: 562,003. Fire-extinguishing. CHROBOK, P. Oct. 27, 1942, No. 15056. [Class 47 (ii)] In a fire extinguisher of the type comprising a container for a fire extinguishing powder, e.g. sand, and a container for a propellant pressure fluid such as carbon dioxide or nitrogen, the pressure fluid container 18 is separate but removably supported on the powder container 10 and the connecting tube 16 leads to an annular distributing tube 15 provided with tangential discharge nozzles 25, additional apertures 26 and downwardly extending tubes 20-23 of different length, the tube 20 extending to the bottom of the tapered container 10 near the spirally grooved discharge nozzle 24 which may be fitted with a discharge tube 28<1> and metal tube 28<2>, the whole arrangement effecting intimate mixture of the powder and fluid which issues from the nozzle as a spirally rotating jet.

Title: Improvements in trigger mechanisms for automatic firearms
IPC: F41A19/33
Filed: 1943-09-14
Abstract: 573,029. Automatic smallarms. LANCHESTER, G. H. Sept. 14, 1943, No. 15072. [Class 119] The operative-element of a change-fire device is a conical finger 18 mounted eccentrically on the rear end of a spindle 20, which is lockable in either one of three angular positions by a finger-lever 23 and a spring latch 25. In its highest position, as shown in Fig. 3, the cone 18 engages an inclined notch 14a leading into a central bore 15 in the end of the trigger-bar 10 by which the sear 12 (pivoted at 28) is actuated. When the trigger 1 is pulled, the bar 10 is pushed forwardly by the trigger nose 8 and the incline 14a rides on the point 17 of the cone 18 to the position shown in dotted lines and disconnects the bar from the trigger. The sear spring 29 then reacts to re-set the sear into cocking position, thus permitting single shots only to be fired. For automatic fire, the spindle 20 is rotated 180 degrees to bring the cone 18 to its lowest position in which it engages a second inclined notch 14b in the end of the trigger-bar. In this case, the cone holds the bar in engagement with the trigger, so that the sear 12 is depressed so long as the trigger is held pulled. For the " safe " setting, the spindle 20 is rotated to an intermediate position, indicated at 41 in the end elevation of the trigger-bar shown in Fig. 4, in which position the conical point 17 engages a cylindrically-curved surface 16 at one side of the notches 14a, 14b. Movement of the bar to fire the weapon is thus prevented.

Title: Improvements in receiving arrangements for radio direction finder systems

Filed: 1938-05-20
Abstract: 495,554. Directive wireless signalling. BERRY, R. J. (Lorenz Akt.-Ges., C.) May 20, 1938, No. 15101. [Class 40 (v)] Relates to direction finders of the kind described in Specification 447,707 in which the number of " dots " or " dashes " received from a rotating beacon is counted from a zero or starting signal. In order to provide a continuous, as distinct from an intermittent indication of direction, two counting-devices Z1, Z2 are controlled by a relay U, u1 so that one gives a position indication during the period when the other is being re-set. The reversing relay U may be operated by a specific signal from the transmitter, or by a mechanical make-and-break switch, Fig. 2 (not shown), which is energized locally. Lamps L1, L2 at the rear of the indicators Z1, Z2 are lit by a relay u2 preferably forming part of the relay U.
Patent GB-1589800-A (GB)
Title: Tissue paper-making machine
IPC: D21F9/00
Filed: 1978-04-18
Abstract: The tissue-paper machine contains, in a known way, a two-wire forming part with a run-on box (10a), a supporting cloth (11a), a covering cloth (12) and a forming roller (13) as well as, functioning as a drier, a glazing cylinder (50) which, together with a press-suction roller (40), forms a pressing point (N1). So that tissue paper with great softness, a high specific volume and high absorbency, at the same time with good strength, can be produced, a marking press cloth (32) is so arranged in the machine that it runs through the pressing point (N1), where it presses its marking into the paper web (W) and, in addition, also serves as an element further supporting the web (W), so that the web (W) is transferred on to the marking press cloth (32) by means of pick-up devices (30a, 30 alpha ). The supporting cloth (11a) can also itself be designed as a marking press cloth and be guided through the pressing point (N1). <IMAGE>

Title: Process and apparatus for the electrolytic reductive coupling of olefinic compounds
IPC: C25B9/17
Filed: 1963-04-19
Abstract: In the electrolytic hydrodimerisation of an olefinic compound or the electrolytic reductive coupling of different olefinic compounds in an electrolyte in contact with the cathode of an electrolysis cell, an olefinic compound is used as solvent to extract the hydrodimerised or reduction coupled product from the electrolyte, the olefinic compounds being in the liquid phase under the conditions of electrolysis and extraction.  Preferably the reactant olefinic compound or compounds should be used as the extracting solvent. Typically the electrolyte is an aqueous salt solution and should comprise cations which are not discharged at the voltages required for olefinic coupling. Suitable salts are amine and quaternary ammonium salts of a sulphonic or alkyl sulphuric acid which should be present in such concentration that they do not provide an electrolyte with which the olefinic compound is miscible.  The olefinic compound should be present in at least 10% by weight of the aqueous salt solution and should form a supernatant layer over the electrolyte. In the case of 1:3-butadienes in solution only small amounts of water should be present since otherwise simple reduction may occur.  In examples acrylonitrile is hydrodimerised to adiponitrile and the product is extracted with acrylonitrile either separately from or during the electrolysis.  The cathode employed is a metal with a hydrogen over-voltage greater than that of copper.  As shown the cell, e.g. of glass, contains a mercury cathode 5, electrolyte 6, supernatant layer of olefinic compound(s) up to level 15 of the overflow tube leading to a water wash vessel 16, from which a supernatant layer of olefinic compound and coupled product flows to a boiler 1 leading to a condeser 3 from which olefinic compounds is returned to the cell adjacent the cathode. The anode 10 is located in a chamber defined by a porous cup diaphragm, e.g. of unglazed porcelain, containing an aqueous acid or salt solution.  A stirrer 13 and thermometer 11 are provided.  <PICT:1041462/C6-C7/1>

A reversible pump-turbine i.e. a hydraulic machine which in one direction of flow and of rotation acts as a turbine and in the reverse direction of flow and of rotation acts as a pump is provided with adjustable guide vanes which are arranged when rotated to clear one another with their respective leading and trailing edges, the arrangement being such that the vanes may be turned from their normal position, which they assume for both turbine and pump operation, into a position inclined the opposite way to cause water to impinge on the runner in the sense of rotation for pump operation until a sufficient speed is reached when the driving of the rotor is taken over by a synchronous motor-alternator, the guide then being returned to their normal position. In normal operation either as a pump or turbine, the guide vanes 3 are in alignment with the fixed stay vanes 2. The leading and trailing edges of adjacent blades clear one another so that the vanes can be turned through a large angle so that the direction of fluid flow on to the blades is reversed. Accordingly, by turbine action, the blades 5 are driven in the reverse direction i.e. the pumping direction. The synchronous motor-alternator is then energized and pumping begins. The guide vanes 3 are then returned to their normal position.
