Title: Improvements in and relating to internal combustion ramming devices
IPC: E02D7/12
Filed: 1936-04-30
Abstract: 474,395. Power hammers. MECOBRENNKRAFT - MASCHINEN GES., April 30, 1936, Nos. 12322, 12323, and 12324. Convention dates, April 30, 1935, Nov. 21, 1935, and March 5, 1936. [Class 83 (iv)] An internal-combustion ram operates on the Diesel cycle. As the ram cylinder rises due to an explosion air is compressed below the piston 3 and is transferred by the passage 13 and spring non-return valve 6 to the space 11 to scavenge the products of combustion. This air passes through passages in a disc 9 to give it a helical motion. When the ram drops this air is compressed and fuel is injected by the pump 7 operated by its rod 16 engaging the casing 20. In a modification, Fig. 7, the pump is actuated by an eccentric 29 carried on a weighted arm 26. The commencement of the ram's decent causes the rod to move till it engages the adjustable stop 31 giving a small early injection of fuel but when the blow is struck the weight 27 descends injecting the main fuel charge. The ram may be started .by being dropped or by a small explosive charge inserted in the cylinder and fired by a trigger.

Title: Improvements in or relating to methods of separating plutonium
IPC: G21C19/46
Filed: 1947-05-08
Abstract: 831,862. Plutonium recovery. UNITED KINGDOM ATOMIC ENERGY AUTHTHORITY. May 8, 1947 [June 5, 1946], No. 12528/47. Class 39(4). Plutonium is recovered from a solution by adjusting the pH to from 3À0 to 6À0 and adding a ferric salt to produce a precipitate of a ferric compound which carries down plutonium. The solution treated may also contain uranium and fission products and may be a residual nitrate solution obtained from a uranium recovery process, for example as described in Specifications 805,000 and 805,001. Preferably ammonium acetate or acetic acid is added to the solution to form a soluble uranium complex and to produce a precipitate of ferric basic acetate on addition of ferric nitrate solution. The solution is then heated to 80‹-100‹C. for an hour or longer without stirring and the precipitate filtered off and washed with a solution containing ammonium acetate and ammonium nitrate to remove uranium. The precipitate is dissolved in nitric acid, the solution saturated with ammonium nitrate and extracted with nitro-methane, diethyl ether, methyl isobutyl ketone, or dipropyl ketone, the plutonium is returned to aqueous solution by extraction with 2N nitric acid and then precipitated by adding potassium iodate; alternatively the ferric precipitate may be treated with concentrated hydrofluoric acid which dissolves the iron, leaving a precipitate of plutonium tetrafluoride. When the uranium content of the original solution is low, the acetate may be omitted and a precipitate of ferric hydroxide formed which carries down the plutonium and is treated in the same way as the ferric basic acetate.

Title: Improvements relating to machines for cutting paper, cardboard and similar sheet material
IPC: B26D5/20
Filed: 1957-04-17
Abstract: 799,630. Guillotine cutting-machines. WERNER, H. H., and RUEDIGER, F. April 17, 1957 [April 18, 1956], No. 12557/57. Class 31 (1). A cutting machine in which the feed saddle is controlled by electrical switchgear connected to and driven in synchronism therewith is characterized in that the switchgear is mounted on a carriage and the switching action is obtained by means of switch cams adjustably mounted on bars along the path of the carriage to co-operate with the switchgear to open or close circuits of electromagnetic controls of couplings for the - saddle drive and the cutter drive, the impulses for operating the said controls being produced by current flowing through electronic valves. As shown, pairs of switch-over and stop contacts 23, 24 secured to a carriage 7 co-operate with pairs of contacts 28, 26 on switch cams 4 adjustably mounted on contact bars 2 exchangeably secured to a base-plate 1. The carriage is clamped by a spring-influenced coupling 10, Fig. 3, to a cable 9 which passes over pulleys 8 and is driven by the feed saddle. The contacts 23, 24 are connected in groups to contacts 29, 30 slidable against guide bars 31, 32 which are connected to the control grids of electronic valves 33, 34, Fig. 5. The valve 33 has in its anode circuit a switch-over relay 35, contacts 36, 37 and a change-speed gearing 38 for reducing the speed of the saddle from fast to slow speed. The saddle is brought to a stop by means of the contacts 24 operating a brake release magnet 39 in the anode circuit of the valve 34. If a switch 41 is turned to the position for automatic operation, a switch 40 causes the coupling 42 for the cutter drive to be engaged. If, however, the switch 41 is turned to the position for semiautomatic operation, the coupling 42 is caused to be engaged indirectly via the switch 40. The coupling 10 is released when an electromagnet 16 is energized and the carriage 7 is returned to ts initial position by means of the cam surface 18 of a movable lever 19, Fig. 2, when an electromagnet 20 is energized, the lever 19 having a notch 21 for engagement by a part of the carriage when the latter is in its neutral position. An indicator pointer 47 attached to the cable 9 and movable over a graduated scale 48 on the base plate 1 co-operates with adjustable contacts 49, 51 on a contact bar 3 secured to the base plate to determine the limits of movement of the saddle. The control bars 2 are connected to two groups of selector switches 5, 52, Fig. 5, and a change-over switch 53 is provided for connecting either group of switches into the control circuit. Signal lamps 54, 55 are provided in the circuits of the selector switches 5, 52 and are operated by the switch 53 to indicate the group of selector switches in circuit. The type of saddle feed is determined by means of preselector keys.

Title: A method of preparing organic pyrophosphates
IPC: C07H11/04
Filed: 1963-03-29
Abstract: Organic pyrophosphates, of formula: <FORM:0979282/C1/1> wherein R1 is hydrogen, alkyl, aralkyl, or substituted or unsubstituted aryl, and R2 is alkyl, aralkyl, or substituted or unsubstituted aryl, are prepared by reacting the corresponding acid organic phosphate with ketane dimer in the presence of an inert solvent.  The reaction is preferably performed under reflux in the presence of an organic base (e.g. tertiary aliphatic or aromatic amines), or an inorganic base (e.g. aqueous alkali metal hydroxide), suitable solvents being ether, dioxane, or acetonitrile.  Suitable R1 and R2 groups include methyl, ethyl, n- or iso-propyl, n- or iso-butyl, phenyl, benzyl, p-nitrophenyl, and p-chlorophenyl radicals.  Preferred proportions of reactants are 1 mole butane dimer:2 moles of phosphate, with about 2 moles of base.  The product may be purified in the free state or as a salt, (e.g. the barium salt). Examples are given for the preparation of (1) barium diphenyl pyrophosphate; (2) barium bis-p.chlorophenyl-pyrophosphate; (3) tetra-p.nitrophenyl pyrophosphate; (4) tetra-benzyl pyrophosphate; (5) tetraphenyl pyrophosphate; (6) tetra-ethyl pyrophosphate.  The pyrophosphates are useful phosphonylating agents for carbohydrates, nucleosides, and other naturally occurring compounds having a hydroxyl group.

Title: Improvements relating to the production of penicillin
IPC: A61K31/43
Filed: 1949-07-14
Abstract: Crystalline ammonium penicillin salts are manufactured by reacting penicillin acids, dissolved in a water-immiscible organic solvent, with ammonia in the presence of one or more water-miscible aliphatic ketones (e.g. acetone or butanone).  The reaction is advantageously effected by passing in gaseous ammonia until the pH reaches about 5-9 (preferably about 7 in the case of relatively crude solutions).  In an example, a crude solution of penicillin salts is acidified with sulphuric acid to pH 2 and extracted with chloroform, the chloroform extract is dried and filtered, acetone is added and gaseous ammonia passed through the agitated solution until the pH is 7.8.  The precipitate is separated, washed with acetone and ether and dried, and may be recrystallized from a water-miscible organic solvent, e.g. acetone or butanone.  Specification 578,590 is referred to.
