Title: Improvements relating to bis-quaternary ammonium compounds
Inventor: GAIMSTER KENNETH
Filed: 1953-09-03
Abstract: The invention comprises bis-quaternary compounds, the cation of which is of the formula <FORM:0750346/IV(a)/1> where R1, R2 and R3 each represent methyl or ethyl and A is an aliphatic hydrocarbon chain of 3-8 carbon atoms containing at least one unsaturated (ethylenic or acetylenic) linkage.  Preferably R1 and R2 are ethyl groups and R3 is methyl, preferred compounds being the but - 2 - ene - 1:4 - bis - (diethyl methyl ammonium) salts and but-2-yne-1:4-bis-(diethyl methyl ammonium) salts.  The anions of the compounds may, for example, be bromide, chloride, iodide, hydroxide, methyl sulphate, tartrate or citrate.  The products may be made by reacting a compound of the formula X-A-X with a compound R3Y wherein one of X and Y is the acid residue of an ester which is reactive to form quaternary salts, e.g. chlorine or bromine, and the other represents the group -N(R1R2). For example, a dibromide.  Br-A-Br is reacted with an amine N(R1R2R3), The products obtained by these processes which suitably will be in the form of bromides, may be converted into salts having other anions such as the bitartrate or phosphate.  An acetylenically-unsaturated compound may be converted into an ethylenically unsaturated compound by catalytic hydrogenation using, for example, a lead-poisoned palladium catalyst.  In examples: (1) 1:4-dibromo-but-2-yne is reacted with diethylmethylamine to give but-2-yne -1 : 4-bis-(diethyl methyl ammonium bromide); (2) trans-1 : 4-dibromo-but-2-ene is reacted with diethyldimethylamine to give transbut - 2 - ene - 1 : 4 - bis - (diethyl methyl ammonium bromide); (3) cis - 1 : 4 - dibromo - but - 2 - ene is treated by the method of (2) to prepare cis - but - 2 - ene - 1 : 4 - bis - (diethyl methyl ammonium bromide); and (4) 1 : 6-dibromohexa-2 : 4-diyne is reacted with trimethylamine to give hexa - 2 : 4 - diyne - 1 : 6 - bis - (trimethyl ammonium bromide).  The products are useful as ganglion-blocking agents.  Dibromoalkenes and alkynes such as the starting materials of the examples are made by brominating the corresponding diols, e.g. by treatment with phosphorus tribromide. But-2-ene-1 : 4-diol is made by catalytic hydrogenation of but-2-yne-1 : 4-diol.  Bis-quaternaryammonium alkanes are obtained by catalytic hydrogenation of the products of the invention.  For example butane-1 : 4-bis-(diethyl methyl ammonium bromide) is made by hydrogenating the products of Examples 1 and 2.  Specifications 714,867, 723,203 and 748,224 are referred to.

Title: Improvements in or relating to pulsators for milking machines
IPC: A01J5/10
Filed: 1927-09-16
Abstract: 278,687. Aktiebolaget Separator. Oct. 9, 1926, [Convention date]. Cow-milkers.-In milking-machines employing a secondary pulsator having a reciprocating piston which is operated by pressure impulses from a primary pulsator, in order to obtain smooth and complete motion of the piston, provision is made for the application thereto of auxiliary pneumatic pressure from the moment it passes a given intermediate position approaching one end of its stroke until the moment it passes a given intermediate position when receding from that end. The auxiliary pressure is obtained from air which is simultaneously being supplied to teat cups. As shown, the reciprocating piston B works in a casing A having connections G, H to the teat cups, and connections I, J, Q to vacuum, the primary pulsator, and the atmosphere, respectively. The piston has recesses C, D communicating with chambers E, F in the piston ends, and it also has spaced flanges S, R. T. In the position shown, the cups attached to the connections H, G are respectively under vacuum and atmospheric, pressure, and there is also atmospheric pressure on the left-hand side of the solid flange R. When a pressure impulse is received from the primary pulsator through the connection J the piston does not begin to move over to the left until the transmitted pressure overcomes the atmospheric pressure on the flange R. First closing the port L and the channel Q, the piston then opens the channel Q to the space on the right-hand side of the flange R, the port K to vacuum, and the recess C to the connection J, and atmospheric pressure coming in behind the flange assists in effecting the completion of the stroke.

Title: Electrochemical cell
IPC: G01N27/49
Filed: 1967-05-26
Abstract: 1,127,846. Electro-chemical analysis. BECKMAN INSTRUMENTS, Inc. May 26, 1967 [July 1, 1966], No. 24500/67. Heading G1N. In a polarographic or galvanic cell for determining the oxygen content of a sample medium in which two electrodes 22, 30, Fig. 1, are immersed in an electrolyte 20, and separated from the sample by a membrane 38, e.g. of PTFE or polyethylene, permeable to the oxygen only, the thin film of the electrolyte, between the membrane 38 and electrode 22 is purged of any oxygen which would interfere in the measurements on the sample by electro-chemical or chemical scavengers provided in the cell, The electro-chemical scavengers may comprise two electrodes, the cathode 42 having the form of a cylinder surrounding but spaced from a member 18 carrying the measuring cathode 22 and the anode being formed by a wire coil 43 wound round the member 18. Either a voltage is applied between the two electrodes or they are short circuited. If the former type of system is used in a polarographic cell or the short circuited electrodes are used in a galvanic cell, the electrode 43 may be omitted, the electrode 30 being common to both cathodes, Fig. 2 (not shown). In a modification of the scavenger having short circuited electrodes, the anode may be constituted by a coating (40), Fig. 3 (not shown), covering the upper part of the cylindrical cathode (52), or a wire (56), Fig. 4 (not shown), wound round it, the two being short circuited by contact with each other. In the embodiments, the cathodes of both the galvanic cell and the galvanic scavengers are made of a noble metal, e.g. gold or silver, the anodes of a base metal e.g. zinc, cadmium or lead and the electrolyte of potassium hydroxide. For the polarographic cell and equivalent scavenger the cathodes are made of a noble metal as before but the anodes are made of silver and the electrolyte of potassium chloride. The chemical scavenger, which effects the removal of dissolved oxygen by direct chemical action may take the form of a cylinder, e.g. like the cathode 42, the coil 43 and leads being omitted, or of a wire or cylinder around the bottom of the member 18. It may be made from an active metal, e.g. magnesium, thallum, cadmium or zinc. With this scavenger the electrodes of the cell and the electrolyte depend only in the manner of operation of the cell.

Title: Improvements in or relating to automatic winders for cables, flexible tubes and the like
IPC: H02G11/02
Filed: 1940-02-07
Abstract: 536,579. Tension limiting devices. CARLING, E. C. Feb. 7, 1940, No. 24604/39. [Class 78 (v)] A winding-in apparatus which imparts drive to the reservoir drum only when the cable, flexible tube &c. is slack comprises a flat or V-shaped friction drive train 21, 22, 23, of which the wheel 21 is on, or driven by, an electric motor or a road wheel of the apparatus and the ring 23 is attached to the winding drum D. The intermediate wheel 22 is carried by an extension 25 of a bell-crank pivoted on the drum axis 6, the upper arm 24 of the bellcrank carrying a pulley 18 over which the cable 12 is rove. The weight of the bell-crank members, or a spring or rubber block, biasses the wheel 22 into contact with both the wheel 21 and the ring 23, thus imparting drive to the drum D. Tension on the cable 12, however, pulls the wheel 22 away from the drive wheel 21 and allows the drum to stop. The wheel 22 may be mounted on a member 25<SP>1</SP> pivoted at 25<SP>2</SP> to the extension 25, a spring 25<SP>3</SP> serving to press the wheel 22 positively against the rim 23. The current may be led to the motor from the cable 12 by way of brushes 13, 14 and slip rings 8, 9 on the drum. Above the pulley 18 is another guide pulley which may swivel about a vertical axis. In modifications the pivoted arm 24 may control a motor switch or a magnetic driving clutch. The requisite tension in the cable for interrupting the drive to the drum may be variable, e.g. a clutch with adjustable slip may be employed. The payed out cable may be laid in hooks, troughs &c. suspended from a roof.

Title: Improvements in or relating to connectors for electric power cables
IPC: H01R4/62
Filed: 1956-08-10
Abstract: 816,635. Sleeve couplings cable couplings. TATE, A. E. Aug. 7, 1957 [Aug. 10, 1956], No. 24612/56. Class 38 (1). In a connector of the kind comprising a sleeve which is crimped on to a conductor, the sleeve is formed from a metal different from that of the conductor and has a liner either of the same metal as that of the conductor or of a metal which produces negligible electrolytic action between it and the conductor, means being provided for effecting a moisture-proof seal between at least the outer end of the sleeve and liner. In Fig. 1 an aluminium sleeve 12 forming part of a jumper connector has a copper liner 14 closed at its inner end and screwthreaded at its outer end which projects from the sleeve. A resilient sealing washer 16 placed over the projecting end of the liner is compressed to seal the joint between sleeve and liner by nuts 18, 19 screwing on to said projecting end. Fig. 3 shows a sleeve connector for connecting a copper conductor 23 and an aluminium or aluminium sheathed conductor 21. A copper liner 24 receives the copper conductor and is sealed at its outer end as in the previous embodiment whilst the aluminium sleeve 20 engages directly the conductor 21. In the case where two copper conductors are to be joined (Fig. 4, not shown), a copper liner which extends throughout the length of the bore of the sleeve is provided, said liner projecting from both ends of the sleeve and being sealed at each end as before. Fig. 5 shows a modification of the construction shown in Fig. 3 wherein the liner instead of being screwthreaded has an enlarged head 26. Prior to compressing the sleeve on to the conductors 21, 23, the centre portion of the sleeve 20 is compressed to grip the liner 24, such compression causing axial expansion of the sleeve which compresses the washer 16 between the end of the sleeve and the head 26. Such a construction may be used in a tapping connector as shown in Fig. 6, wherein the half of the sleeve 20 containing the liner 24 and sealing means is attached to a conventional conductor gripping device 34. Specifications 601,670, 601,690 and 693,367, [both in Group XXII], are referred to.

Abstract: 702,569. Drilling brush-stocks. CARLSON TOOL & MACHINE CO. Oct. 25, 1951 [Nov. 10, 1950], No. 24959/51. Class 83 (3). [Also in Groups XXIII and XXX] A drilling machine for use in brush making comprises a conveyer to which brush backs are automatically fed and moving in a closed path through a drilling station and a tufting station the conveyer being supported on a carrier mounted for movement relative to the drilling and tufting stations and the automatic feeder being mounted on the carrier to move therewith. In the machine shown, which is for making tooth brushes, conventional drilling and tufting mechanisms (not described), operate simultaneously and the conveyer is moved bodily after each operation of the drill and tufter to move the brush back so that three rows of holes are drilled in one back and the holes in another back are successively tufted. The conveyer, Figs. 1 and 3, comprises a frame 30 carrying two sprockets 37, 38 carrying an endless chain with projecting jaws 47a, 47c. The brush backs automatically drop, or are pneumatically inserted endwise, Fig. 6 (not shown), from a hopper 32 between the jaws which close when the line of travel of the conveyer straightens, resilient inserts 62 serving to grip the backs firmly. The jaws open when the chain passes over the second sprocket and the brush backs fall into a chute 33. The portions 40, Fig. 10, of the jaws are provided with tongues which slide in guides 45, 46 in the frame. To present new brush backs to the drill and tufter the conveyer belt is periodically moved rapidly forward by a pneumatic ram 70, Fig. 3, through a ratchet and pawl 72, 74, the amount of travel being determined by the length of the adjustable piston-rod 71 and limited by a second ratchet and pawl 81, 87. Compression springs 101, 102 cushion the blow. The conveyer frame is mounted on two lateral slides 115, 116 and a longitudinal slide 100, Fig. 10, and a nose 160 is provided which rides on a cam 161 and so determines the depth of penetration of the drill and tufters.
