Title: Arrangement for practising firing by means of compressed air from machine guns and other light guns
IPC: F41B11/55
Filed: 1936-12-16
Abstract: 486,794. Adapting automatic guns for practice fire. OESTERREICHISCHE AGA-WERKE AKT.-GES. Dec. 16, 1936, No. 34547. Convention date, April 27. Addition to 485,205. [Classes 92 (ii) and 119] Relates to automatic guns adapted for practice fire with pneumatically propelled pellets and having means for simulating recoil as described and claimed in the parent Specification. According to the present invention, the compressed air passages 18, 19 in the pneumatic cylinder 12 which respectively effect discharge of the pellet and force the piston 8 rearwards are opened simultaneously at the end of the forward movement of the piston. As in the parent invention, the compressed air for discharge is supplied through a valve 16 the stem 15 of which engages a groove 9 in the piston 8 and the air passes through a hollow stem 7 on the piston which also serves to push the pellets into the practice barrel 25 from a spring-feed magazine 30. The piston 8 is connected to a cocking member 1 moved rearwards against the action of a recoil spring (not shown) and retained by a trigger. On release, the piston 8 moves forwards and raises the stem 15 to admit pressure to a chamber 17. At the end of the forward movement, the front part 8<1> of the piston opens the passage 18 to admit air to the discharge passage 10 and simultaneously a shoulder 13 on the part 8<1> moves a sleeve 11 to open passage 19 to admit air in front of the piston to cause recoil of the parts. On recoil, a shoulder 14 returns the sleeve 11 and opens the exhaust passage 20. The Specification as open to inspection under Sect. 91 describes also a pellet magazine in the form of a helical tube fed from a hopper with the assistance of air pressure derived from the gun. This subject-matter does not appear in the Specification as accepted.

Title: Manufacture of polyurethanes
Inventor: TWITCHETT HARRY JAMES
IPC: C08G18/16
Filed: 1961-09-27
Abstract: Polyurethanes are prepared by reacting organic polyisocyanates with hydroxyl group containing polymers containing at least two isocyanate reactive groups per molecule in the presence of a tertiary amine and a lead salt of a thio-acid of phosphorus of the formula <FORM:0990635/C3/1> or <FORM:0990635/C3/2> wherein X and X1 stand for the same or different organic radicals and Z stands for the hydroxyl or thiol radical.  The radicals X and X1 may be straight chain or branched alkyl, cycloalkyl, aryl, aralkyl and hetero-atom interrupted alkyl radicals or they may be substituted hydrocarbon radicals or diradicals joining two phosphorus thio-acid molecules or X and X1 may together be a diradical.  Many such radicals are specified as are many lead salts.  The hydroxyl-containing polymer may be a polyester, polyesteramide or polyether polyol or a mixture thereof and many starting materials for the preparation of such polymers are listed. Many tertiary amines and organic polyisocyanates are also listed. The tertiary amine may be present wholly or in part as a complex of the lead salt.  The reaction mixture may also contain surface-active agents, e.g. oxyethylated phenols, fatty alcohols such as oleyl alcohol, sulphated methyl oleate, polyalkylsiloxanes and block copolymers thereof with polyalkylene oxides; flame-retardants such as tri-b -chloroethyl phosphate and antimony oxide; plasticizers such as tricresylphosphate and dioctyl phthalate; pigments and fillers, such as carbon black and silica; antioxidants such as t-butylcatechol and other catalysts such as iron and manganese acetylacetonate, dibutyltin dilaurate, stannous octoate, lead acetate, basic lead acetate, lead 2ethylhexoate and a zinc salt of a sulphur containing phosphoric or phophini acid as defined in Specification 990,632.  The process of the invention may be used to prepare polyurethane lacquers or polyurethane foams.  In the latter case, water or a low boiling point liquid such as a halocarbon is used as the blowing agent. Examples are given of the preparation of lacquers and foams by the process of the invention: in comparative examples the catalyst is either omitted or it is a tertiary amine.  The Provisional Specification is not limited to the preparation of polyurethanes but relates to the preparation of any urethane group containing material from any hydroxyl containing compound.  Specification 990,636 also is referred to.

Title: Improvements in or relating to electric switches, particularly for electric irons
IPC: D06F75/26
Filed: 1935-12-13
Abstract: 467,206. Retractive switches for electric irons; two-part couplings combined with switches. PERL, A. H. F. Dec. 13, 1935, No. 34698. [Class 38 (v)] [Also in Group XXXVI] A switch,. adapted to be mounted in an electric iron or a connector therefor, has a handle 32 adapted to be pressed against the handle of the iron to close the circuit ; when the hand is removed, the handle 32 moves into the dotted position (Fig. 5) and if the iron is stood up on end the lever 32 assumes an intermediate position which is " on " or " off " according to whether the lever has been moved there from one or other of its extreme positions. This is made possible because of the lost motion involved in the actuation of the switch. The switch comprises a contact-carrier 16 pivoted at 18 and connected by a dead-centre spring arrangement 27 with a member 24 pivoted at 23 and provided with cam surfaces 50 which are engaged by a pin 20 on a crank 21. The crank 21 may have a key 22 engaging a slot in the hollow spindle 18 which is itself rotated by the handle 32 having ends which are slidably.keyed in a slot in the spindle. Thus operation of the handle 32 turns the spindle 18 and the pin 20 engages one or other side of the hole 50 causing the member 24 to pivot about 23 and operate the switch. Retractive springs acting on the spindle 18 tend to hold the switch off.

Title: Process for the conversion of bituminous substances or of bitumen and filler mixtures, in particular those having a high melting point, into protective coatings on constructions and the like by spraying
IPC: B05D1/02
Filed: 1935-12-16
Abstract: In the production of bituminous coatings, e.g. on buildings or in road-making, particularly from bituminous substances of high melting point or of high filler content, the hot bituminous mass is placed under pressure by means of a continuous delivery pump or by means of an inert gas, and is sprayed through a homogenizing nozzle with the avoidance of any sudden changes of velocity acting upon the material. Clogging of the apparatus, separation of the filler, and the danger of spontaneous ignition of the bitumen are thereby avoided.  Pipes through which the material passes should be without sudden alterations of cross-section, and byepasses or compensating spaces may be provided at bends, so that the material is carried to the nozzle with a constant and uniform movement. Steam, superheated if necessary, and nitrogen are mentioned as p  suitable pressure media, and a compressed inert gas may also be supplied at the nozzle exit, to improve atomization.  When a continuous acting pump is used, the container may be open, but the heated bituminous mass is preferably blanketed with an inert gas, such as nitrogen.

Abstract: 429,954. Pressure-regulating valves. WORKMAN, T. A., Gothic Lodge, Hayling Island, Hampshire. Dec. 13, 1933, No. 35042. [Class 135] A pressure regulator of the kind having a piston actuated main valve opening in the direction of flow controlled by an auxiliary valve has the auxiliary valve formed as a double beat valve housed in the same casing as the main valve. The main valve 1 has a guide spindle 41 co-operating with a socket in a detachable cap 28, and a spindle 4 connecting it to a leaky piston 2 of larger diameter than the valve. The leakage past the piston may be supplemented by a passage 19 controlled by a throttle 18 or by a supplemental spring loaded valve. The piston has an adjustable stop 20 to prevent the valve hammering on its seat. The auxiliary valve 3 is coupled to its actuating diaphragm 12, which is loaded by a spring 16, through a resilient member 22 such as a corrugated disc. In a modification a metallic diaphragm working between a pair of perforated cupped discs is used to operate the auxiliary valve. In this form the thrust of the loading spring is transmitted to the diaphragm through a bellows and a volume of liquid. The bellows may be used to actuate the auxiliary valve. A damping device may be associated with the main valve to prevent chatter.
