Title: Power-operated tool
IPC: H01R43/045
Filed: 1959-11-18
Abstract: 881,668. Jointing by stamping. BURNBY CORPORATION. Nov. 18, 1959 [Nov. 24, 1958], No. 39089/59. Class 83 (4). A fluid-operated crimping tool comprises a fluid-operated piston, a frame having a plurality of movable means for operating a pair of die parts mounted therein, means for supporting an article on said frame, and means whereby said piston will cause both die parts to move in a straight line path towards each other and towards the article supported in a stationary position between said die parts. The tool comprises a cylindrical body 10 containing a spring-loaded fluid-operated piston 17 and a frame 11 bolted to the cylinder. The piston has an extension 19 of square cross-section provided with a cam surface 20 and a bearing surface 21. The extension is connected to the piston by means of a sealed hemi-spherical joint 23 and the piston return spring 28 enters a bore 26 in the extension to which it is attached by a pin 27. A crimping head is mounted on the frame 11 and houses upper and lower dies 30 and 31. The piston operates a rocker mechanism comprising a rocker 45 pivoted to the frame at 46. The rocker has rollers 48 and 49 for engaging the piston extension and a die-operating plunger 43 respectively. Roller bearings 56 and 57 on the frame maintain the piston extension in proper alignment. The plunger 43 operates the lower die 31 and also the upper die 30 through an adjustable link 40 and a pivoted lever 32. The power operation of the tool is controlled by a pivoted lever 59 operating a conventional valve unit 64 for supplying pressure fluid to the cylinder 10. The valve is spring-loaded at less than the operating pressure so that once the valve is opened by movement of the handle 59 the piston 17 must travel its full distance, i.e. producing a full crimp, before the pressure is released through an exhaust port 122 so enabling the spring-loaded valve to close and the dies to return to their fully open position. The tool includes a magazine feeding mechanism comprising a compartment 81 for storing a plurality of cartridge blocks 83. Spring-loading means 90 attached to the cover of the compartment urge the cartridge blocks to the bottom of the compartment where the lowermost block is engaged by a spring-loaded driver 98 which successively feeds each connector in the block into the crimping dies. Each cartridge block rectangular in shape and made of polyethylene or nylon plastic material is formed with a series of spaced bores, each provided with shoulders 108, 109 (Fig. 5), for receiving the connectors. The connector barrel 102 which is to be crimped to the bared end of a wire 103 (Fig. 5), extends beyond the edge of the cartridge block so that as the cartridge block passes into a feed slot 99 in the tool the connector barrel 102 is accommodated within the die grooves 104, 105 (Fig. 6). A stop 106 engages the connector barrel and positions each connector in the dies. After removal of the crimped connector and cable the cartridge block advances until the next connector engages the stop in readiness for the next crimping operation.

Filed: 1975-09-24
Abstract: 1517777 Steam irons HOOVER Ltd 24 Sept 1975 [7 Oct 1974] 39127/75 Heading D1A A steam/dry iron includes a manually movable knob 80 connected to a valve member 46 to provide three spaced positions with respect to a valve orifice 58 allowing no-flow, limited steady flow or maximum steady flow from a water reservoir 22 to a steam generating chamber (14) and then via steam passageways (16) to orifices (18) in an electrically heated soleplate (12). As shown piston 60 on member 46 prevents water flowing through orifice 58 and the iron operates dry. Lifting member 46 allows water to enter cylinder 56 through notches 54 and flow through orifice 58 (Figure 3, not shown). Moving member 46 from the latter position downwards causes piston 60 to eject water through orifice 58 giving a momentary pressurised steam pulse through orifices (18), (Figure 4, not shown). Moving member 46 to the uppermost position (Figure 5, not shown) removes metering pin 66 from the orifice giving maximum steady flow. Thumb knob 80 is pinned to member 46 for pivoting relative to handle 24 and may be latched in the no-flow position. A button (32) operates a pump to spray water from a nozzle (34).

Patent GB-1082060-A (GB)
Title: Aminopyrazinoic acids and their esters
Inventor: CRAGOE EDWARD JETHRO
IPC: C07D241/28
Filed: 1964-10-06
Abstract: The invention comprises compounds of the general formula <FORM:1082060/C2/1> in which R1 is a chlorine atom, a C1-C5 alkyl radical or a phenyl radical; R2 is a chlorine atom, a C1-C5 alkyl, or a cycloalkyl or phenyl radical; at least one of R1 and R2 being chlorine, and R3 is a hydrogen atom or a C1-C5 alkyl radical.  The esters of the above formula may be prepared by reacting a 3-amino-pyrazinoic acid compound of formula <FORM:1082060/C2/2> in which R4 is a hydrogen atom, a C1-C5 alkyl radical or a phenyl radical; R5 is a hydrogen, chlorine, bromine or iodine atom or a C1-C5 alkyl or a cycloalkyl or phenyl radical, at least one of R4 and R5 being hydrogen or halogen, and R6 is a C1-C5 alkyl radical, with sulphuryl chloride.  The esters may be hydrolysed to give the corresponding acids.  The starting 3-amino-pyrazinoic acid compounds having a hydrocarbon group in the 6-position may be prepared from the corresponding 6-substituted-3-amino pyrazinamides by heating with sodium hydroxide solution, acidifying the sodium salt so obtained to give the free acid and converting this to an ester e.g. by reacting with methanol. Starting materials having a halogen in the 6-position, for example methyl-3-amino-6-chloropyrazinoate and methyl-3-amino-6-iodopyrazinoate are made by the direct halogenation of methyl - 3 - aminopyrazinoate.  3 - Amino - 6-cyclohexylpyrazinamide which is used for producing the starting material 3-amino-6-cyclohexylpyrazinoic acid is obtained by reacting aminomalonamidamidine dihydrochloride with cyclohexyl glyoxal.  The new compounds may be used as intermediates in the formation of guanidine derivatives. For example, metallic sodium dissolved in propanol is treated with guanidine hydrochloride, methyl 1-3-amino-5,6-dichloropyrazinoate is added to the resulting guanidine solution and (3 - amino - 5,6 - dichloropyrazinoyl)-guanidine hydrochloride is separated; this compound may be further reacted with dimethylamine to give (3 - amino - 5 - dimethylamino - 6 - chloropyrazinoyl) guanidine.
