Title: Improvements in or relating to Explosively Actuated Tools
IPC: B25C1/08
Filed: 1966-08-16
Abstract: 1,158,484. Cartridge-actuated tools. UNITED SHOE MACHINERY CORP. 16 Aug., 1966 [16 Aug., 19651, No. 36520/66. Heading B4C. An explosively actuated tool adapted to drive fasteners, such as nails, into structures comprises a ram 38 slidable in a barrel 30, a magazine 45 for a plurality of explosive charges 46 which can be fed one by one into a combustion chamber 74a under the action of a transfer means 68, 70, a firing pin 80 being provided for igniting the explosive charges 46. The barrel 30 is connected to a breech block 20 which is slidably mounted in a housing 11, 12. The explosive charges are in the form of pellets and contained in a removable container 45 adapted to be located within a bore 27 formed in the breech block. The pellets are urged towards a transfer lever 68 by means of a follower 43 loaded by a spring 44 and mounted in a tube 42; the tube is connected by a bayonettype joint to a guide tube 40 secured to the breech block. In operation, after inserting the container of explosive pellets, the barrel is moved relative to the housing against the action of a spring 51 thereby causing a cam on a casing 60 movable with the barrel to actuate the transfer lever thereby moving the endmost pellet into a bore 74. Upon the return movement of the barrel a second cam on the casing actuates a bolt 70 which moves the pellet into the combustion chamber 74a; the latter cam is so shaped as to cause the bolt to be locked in the position shown in Fig. 7. A nail is now inserted into the front end of the barrel and the latter pressed against the workpiece so that the barrel moves rearwardly thereby causing a striker 50 to be loaded by the spring 51. Upon depressing a trigger 14, the striker is released and abuts the firing pin 80 causing the pellet to ignite and the explosive gases to drive the ram forward.

Title: Improvements in or relating to injection devices for internal combustion engines
IPC: F02M59/44
Filed: 1932-12-23
Abstract: 402,603. Fuel admission devices. BOUTEILLE, J. J., 3, Rue Leconte-de-Lisle, Paris. Dec. 23, 1932, No. 36523. Convention date, Dec. 24, 1931.

Title: Bridgetype condition sensing circuits
IPC: G01L1/22
Filed: 1971-08-04
Abstract: 1359049 Resistance bridge HONEYWELL Inc 4 Aug 1971 [11 Aug 1970] 36726/71 Heading G1U A strain-gauge resistance bridge 3, 4, 5, 6, receives current from a remote source via two terminals 1, 2 and is so arranged that the total current taken from the supply by the circuit of which the bridge forms part is proportional to the out-of-balance of the bridge resistances. Two independent automatic regulation circuits are used. In the first, the current distribution between the two legs of the bridge is varied to maintain the diagonal out-of-balance voltage substantially zero, and in the second the total current through the two legs of the bridge is maintained constant. The out-of-balance potential from the diagonal of the bridge is amplified 39 and causes current to flow through a transistor 42. This current has to flow from the common positive supply terminal 1, however, and therefore reduces the potential applied to the right-hand arm 5, 6 of the bridge, and as a consequence, also the total current passing through the bridge. However, the total current through the bridge is sensed by a resistor 34, and is compared in a differential amplifier 36 with a Zener-stabilized reference 37, to control the impedance of a Darlington pair 32, to maintain the total bridge current constant. Thus an out-of-balance potential from the bridge causes current to flow through a transistor 42 which tends to reduce the total bridge current but this is maintained constant, and therefore any variation in the current drawn from the remote supply is caused by current flow through transistor 42, which is directly proportional to the bridge out-of-balance. The bridge circuit includes thermistors 12, 19 and 35 and various shunt resistors such as 20, 21, all of which are said to reduce the effect of temperature variations. The bridge also includes a switch 38 and a potentiometer 16 to adjust its zero point, and a switch 29 and a potentiometer 25 to adjust its span. In a modification Fig. 2 (not shown) the total current through the bridge is regulated by adjusting the current through one only of its legs.

Title: Unsaturated aliphatic nitro-diols, their cyclic acetals and process for their manufacture
Filed: 1958-06-30
Abstract: The invention comprises unsaturated aminodiols of the formula CH3(CH2)n-A-CHOH-CHNO2-CH2OH wherein A is a -CH=CH- or -C#EC-radical and n is a whole number from 6 to 11 and cyclic acetals thereof such as the dioxanes of the formula <FORM:0888989/IV (b)/1> and the preparation of these compounds by condensing an aldehyde of the formula CH3(CH2)n-C#EC-CHO with b -nitro-ethanol to give a compound of the formula CH3(CH2)n-C#EC-CNOH-CHNO2-CH2OH which if desired may then be resolved into stereoisomers, reacted with an aldehyde (e.g. benzaldehyde), reduced at the triple bond to the corresponding ethylenic compound by hydrogenation with a Lindlar catalyst or a poisoned palladium catalyst, and where a cyclic acetal is obtained, may be isomerised by heating to an elevated temperature or by treatment with an alkaline agent. Specified products include 1 : 3-dihydroxy-2-nitro-, heptadec-4-yne, tridec-4-yne, pentadec-4-yne and heptadec-4-ene.  Alkyn-1-als of the formula (CH3(CH2)n-C#E C-CHO used as starting materials are made by condensing the appropriate alkyl bromides with sodium acetylide, converting the resulting alkynes into their metal compounds, e.g. with ethyl magnesium bromide, reacting with ortho-formic ester and hydrolysing the resulting acetals to the aldehydes.

Title: Improvements in method and apparatus for inserting coil turns into the slots of a core
Inventor: ARNOLD RICHARD B
IPC: H02K15/06
Filed: 1969-07-22
Abstract: 1,270,861. Inserting stator windings. GENERAL ELECTRIC CO. 22 July, 1969 [29 July, 1968], No. 36819/69. Heading B3A. Apparatus for inserting insulators 75 and side turn portions of a coil 100 into axial slots 97 of a stator core 21, comprises means for guiding the insulators into selected core slots, pusher means for forcing the insulators into the slots and a coil turn feeder assembly including divider blades 56-61 and coil turn feeder blades 41-45. The insulators 75 are initially loaded by inserting them into guide apertures 24 before the stator 21 is positioned over the head assembly 25, Fig. 4. After the insulators have been loaded, a number of coils 96 are wound in turn-receiving gaps of the assembly. Hydraulic cylinders (not shown) provided with push-rods (80), 81 are actuated to move a driver 68 upwardly away from a stationary plate 69, see also Fig. 6 (not shown). This movement is transmitted to insulator pushers 67 carried by the driver, which travel through an increment A until the leading edges 94 of the insulators 75 lag slightly behind turn pushing ledges 47, 51 on the feeder blades 41-45. The driver 68 then engages a stop-nut 22 and a shaft 64 and a feeder blade cylinder 73 move conjointly therewith through an increment B. The nut 22 is threaded on the cylinder 73 and its position determines the length of the increment B, during which the divider blades 56-61 and the coil turn feeder blades 41-45 are driven as as assembly into the stator bore and the coil turns partially enter the slots 97. A stop-nut 23 then abuts the stationary plate 69 thereby stopping further movement of the shaft 64 and of the divider blades. The driver 68 then moves through an increment C during which the cylinder 73 drives the feeder blades 41-45 through the slots to position the coil turns therein and the insulator pushers 67 drive the insulators over the inserted coils. The positions of the stop-nuts 22, 23 are adjusted to suit the stack height of the particular stator 21. The apparatus can be adapted for inserting coils and insulators into stators of four and six pole motors, Fig. 3 (not shown). In a modification a press back fin member (129) trails a coil feeder blade (131) to press back the coils in the slots and a slot entrance fin member (130) forces any displaced coil turns in the slot entrances further back into the slots, Fig. 12 (not shown).

Title: Electrolytic production of metal hydroxide
IPC: C25B1/00
Filed: 1958-11-17
Abstract: 903,426. Producing metal hydroxides by electrolysis. ROLLER, P. S. Nov. 17, 1958, No. 36969/58. Class 41. A method of producing insoluble metal hydroxide, e.g. of aluminium, iron, copper, silver, zinc or magnesium, comprises immersing metal electrodes in a suitable electrolyte, passing an electric current between the electrodes, and resiliently displacing the soft gel film which is formed on the electrodes before the film has set and during passage of the current. The film may be displaced by ultrasonic vibrations in the electrolyte. An apparatus comprises electrodes 11, 12, one face of each of which is contacted by a pliable, preferably flexible, e.g. rubber, wiper 17 secured to a member 16 mounted on a rotatable shaft 19. Direct current from a source 26 is delivered to the cell and the voltage is periodically reversed by a switch 30. Each period of electrolysis in one direction is followed by an equal period of depolarization during which a switch 29 is opened and a switch 38 closed to short-circuit the electrodes 11, 12. The switching operations may be automatically carried out. In a modification, the wiper comprises a gum rubber tube fitted over the member 16. The apparatus may include a plurality of alternating electrodes 11, 12, or two cells, each having one pair of electrodes 11, 12 may be employed, the switching operations being arranged so that one cell is depolarizing when the other is being subjected to electrolysis, and vice versa. It is stated that the wiper may be reciprocated over the electrode faces, but no details are given. Where the anode is liable to be anodized, the oxide film is removed at intervals by a solvent, e.g. a 1 to 5% HC1 solution containing an inhibitor of metal dissolution, e.g. 0.1% of hexamethylene tetramine.

Filed: 1954-12-31
Abstract: In the recovery of uranium from ores thereof by treatment with a mineral acid, the wet ore pulp obtained is treated with coarse pieces of an anion exchange resin to absorb the uranium from the pulp and thereafter the anion exchange resin lumps are separated from the wet ore pulp and the uranium eluted from the resin so recovered.  The preferred leaching acid is sulphuric acid and the leaching is preferably done in the presence of manganese dioxide and after the leaching the wet ore pulp pH is adjusted to about 3.5 with limestone. The ore pulp thus produced may be agitated with "Dowex" (Registered Trade Mark) resin having a mesh size from - 28 to + 35 (B.S.S.) and after agitating with the mixture, the resin may be separated from the pulp by screening.  The uranium absorbed on the resin may be eluted with 1 N nitric acid or hydrochloric acid, 0.9 N ammonium chloride with 0.1 N hydrochloric acid, 1 N sodium chloride, 1 N sulphuric acid, 1 N ammonium sulphate, or 0.9 N sodium chloride with 0.1 N hydrochloric acid.  The preferred anion exchange resins are those which contain quaternary ammonium substituent groups at the exchange positions.  The anion exchange resin particles may be confined to a container having perforated surfaces and the ore pulp agitated with respect to the resin particles in the container.  A three-step adsorption by the resin from three separate batches of wet or pulp may be employed and the resin subjected to a threestage elution. Specification 800,629 is referred to.
