Title: Manufacture of disazo dyestuffs
IPC: C09B35/227
Filed: 1935-04-05
Abstract: Disazo dyes are made by coupling a tetrazotized 4 : 4<1>-diaminodiphenylmonosulphide base with a p-substituted phenol capable of being coupled, neither component containing a carboxylic or a sulphonic group.  An example is given in which tetrazotized 4 : 4<1>-diaminodiphenylmonosulphide is coupled with p-cresol to yield a yellow dye.  The products are useful for colouring cellulose ester and spirit lacquers, and also oils and fats; they may be applied in the graphic arts, e.g. in copper-block printing.  Specification 301,726, [Class 2 (iii)], is referred to.  The Specification as open to inspection under Sect. 91 states that the tetrazo components are derived from diamines of the general formula NH2RSRNH2, where R is an aromatic residue. This subject-matter does not appear in the Specification as accepted.

Title: Means for ensuring safety in use of trackless electric road vehicles such as trolley buses, supplied by overhead conductors
IPC: B60L3/00
Filed: 1932-04-14
Abstract: 387,875. Protective arrangements. SOC. DES V•HICULES ET TRACTEURS ELECTRIQUES (VETRA), 38, Avenue KlÛber, Paris. April 14, 1932, No. 10724. Convention date, April 11, 1931. [Class 38 (iv).] To prevent electrification of trolley buses and other more or less insulated trackless road vehicles supplied by overhead conductors, the two supply lines are maintained at equal potentials of opposite sign with respect to earth, the vehicle body being thus normally at the mean thereof. The body may be connected to the mid-point of a resistance or series of resistances branched across the two supply wires on the vehicle, accidental flow of current therein acting through relays to bring into operation audible, visible, or other signals, or to cut out the main switch on the vehicle or effect other safety measures. The current is collected by contacts 1, 2, a two-pole switch 3 being closed as soon as there is current in the lines by a coil 4 in the line circuit, the direct-current driving-motor 6 being regulated through a controller 5. The vehicle chassis is connected as at 13 to the mid-points of two pairs of equal resistances 7, 8 and 9, 10 branched across the supply circuit, a coil 12 between the connections controlling a relay 11 whereby, in the event of accidental or stray passage of current, such as by an earthing at 14, a luminous or other signal 15 is actuated or a switch in the control circuit 4 may be opened causing the main switch 3 also to open. Alternatively, a low resistance galvanometer may be provided to indicate a drop in the potential of either line. Mechanical or magnetic looking means may be provided whereby, when the relay has been operated, manual resetting is necessary.

Title: Improved method of securing a fixing element in a hole
IPC: C04B40/06
Filed: 1960-03-30
Abstract: 953,056. Wall - plugs; anchoring bolts. BERGWERKSVERBAND G.m.b.H. March 30, 1960 [April 20, 1959 (2); July 7, 1959; Sept. 7, 1959], No. 11134/60. Heading F2H. In a method for securing a fixing element, e.g. an anchor bolt 7, in position in a hole 6 bored to receive it, with a diameter which is oversized relatively to the maximum diameter of the part of the bolt 7 extending in the hole 6, a filling mass is used including at least two constituents brought into contact in the hole to form a mixture which then hardens to secure the bolt 7 in position. At least one of the constituents is in a frangible capsule broken in the hole by the bolt 7 on introduction of the bolt 7 thereinto. The constituents may be each contained in respective frangible capsules and brought into contact on breaking the capsules in the hole 6. The capsules may be inserted into the hole 6 as a single cartridge 1, which may contain the constituents in separate compartments, to be brought into contact on the said breaking of the cartridge 1. The anchor bolt 7 preferably has a helical rib 8 where it extends in the hole 6, and is rotated therein, to exert a worm action on the filling mass to mix the constituents thereof and to pack it in the hole 6. With two capsules or compartments one may contain a synthetic resin in liquid form and the other may contain a hardening agent, e.g. between 8 and 10% of the synthetic resin, with or without an accelerating agent, e.g. between 1 and 2%, and a substance which evolves a gas upon increase in temperature may be incorporated with the synthetic resin and also a filler such as quartz sand, quartz powder or glass fibres. One capsule may contain dry cement mortar and the other may contain mixing water, with or without an accelerating agent. The cartridge 1 may have an outer wall formed with longitudinal lines of weakening, spaced around its periphery, and may have external peripheral ribs of resilient material at axially-spaced positions to bear resiliently against the walls of the hole 6. The outer wall of the cartridge 1 may be glass. The cartridge 1 may have a sealing element 5, at that end which is the outer end when it is inserted in the hole 6, which bears resiliently against the wall of the hole 6 to retain the cartridge 1 therein, having a central aperture for introducing a bolt 7 into the hole 6 and hence to destroy the cartridge 1.

Title: A process for copolymerising unsaturated monomers and the copolymers produced thereby
IPC: C08F2/46
Filed: 1950-05-05
Abstract: A vinyl-type monomer possessing a terminal methylene group joined through a double bond to an aliphatic carbon atom which is joined through a double bond to an aliphatic carbon atom which is joined through a single bond to an atom or group other than hydrogen and through the other single bond to a carbon atom of an organic radical, or a vinyl-type monomer having a terminal methylene group joined to an aliphatic carbon atom through an ethylenic linkage which is in conjugated relationship with another ethylenic linkage, is copolymerized with a dissimilar polymerizable olefinically unsaturated compound by a process which comprises initially polymerizing the vinyl-type monomer under conditions which promote the formation of active polymer nuclei, including polymerization in a liquid medium in which the polymer of the vinyl-type monomer is substantially insoluble, until there is substantially no unpolymerized monomer in the reaction mixture, and thereafter adding the dissimilar polymerizable olefinically unsaturated compound and continuing polymerization. Preferred vinyl-type monomers include methacrylonitrile, methyl methacrylate, methyl-alpha-chloracrylate, methyl isopropenyl ketone, isobutyl 4-ethyl-4-pentenoate, amyl 4-amyl-4-pentenoate, 4 - butyl - 4 - pentenenitrile, butyl 4 - chloro - 4 - pentenoate, 4 - isobutyl - 4 - pentenamide, 4 - amyl - 4 - pentenamide, 3 - chloro - 3 - buten - 2-one, and 4-isopropyl-4-penten-3-one, and preferred dissimilar compounds include acrylonitrile, methacrylonitrile, ethacrylonitrile, styrene, vinylidene chloride, vinyl chloride, bromide, fluoride and acetate, methyl methacrylate, butyl acrylate, acrylic acid, methacrylic acid, methyl isopropenyl ketone and allyl methallyl ether.  The Specification contains lists of other suitable monomers.  The polymerization may be conducted in aqueous emulsion or suspension or the liquid medium may be an organic liquid such as cyclohexane, butane, hexane or benzene, or the monomer itself.  Emulsifying agents employed may be soaps, alkali metal alkyl or alkylene sulphates or sulphonates or salts of higher amines.  The polymerization may be initiated by heat, light, particularly ultra-violet light, or a catalyst which may be benzoyl, acetyl, hydrogen or tertiary-butyl peroxide, persulphuric, peracetic or perphthalic acid, potassium persulphate or tertiary-butyl perbenzoate.  Mixtures of catalysts may be used, and polymerization preferably takes place in the absence of oxygen. Multiple component copolymers can be formed if the second and, if desired, subsequent polymerizations utilize vinyl compounds of the same type as the first monomer.  A mixture of two or more vinyl-type monomers may be initially polymerized and two or more dissimilar polymerizable olefinically unsaturated compounds may be added after the polymerization of the vinyl-type monomer or monomers.

Abstract: 653,339. Jointing; power hammers. GENERAL ELECTRIC CO., Ltd., and SOWTER, A. B. April 23, 1948, No. 11275. [Class 83 (iv)] Cold pressure welding of two metallic surfaces is effected by impact pressure obtained from the release of stored energy. A suitable tool comprises a body 1 closed by a screw-cap 3, a hammer 4 acted on by a spring 7, a striker 24 and an anvil 28. The hammer is raised, compressing the spring, by means of a hand lever 11 which is connected to a pair of slotted links 10 engaging two pins 9 on the stem of the hammer and the hammer is retained in the raised position by a spring-loaded latch 16. Each pair of strands of a cable to be joined are first flattened between surfaces 20, 21 on the body 1 and lever 11 respectively, the amount of flattening being controlled by an adjustable stop 22. After scratch-brushing, the two strands are placed between the striker and anvil; the striker is first raised manually against the action of a spring 26 within the bore of the hammer by pressing up a pin 27 and then allowed to fall again to maintain the strands in position. The latch 16 is then released to allow the hammer to descend on the striker and effect the cold welding. Holes 34, 35 are provided for tommy bars and shims 33 may be fitted under the anvil 28. The striker and anvil may be shouldered, as described in Specification 649,614. The spring may also be compressed by fluid-pressure obtained from an external supply or hand pump, or, instead of a spring, a raised weight, a compressed gas or an explosive charge may be used to supply the welding force. Spot welds on thin aluminium sheet may be made by an automatic centre punch having a suitably-shaped end co-operating with a flat anvil.

Filed: 1925-05-01
Abstract: 234,796. Sinclair, G. W. June 1, 1924, [Convention date]. Crank linkages.-Two shafts in the same or parallel planes and adjustable in respect of their angular relation, are coupled by a link universally jointed to a crank arm on one shaft and having either a simple hinged or a universally jointed connection direct to the other shaft. When the shafts are coaxial, uniform rotary motion is transmitted, but when relatively inclined, rotary motion of the crank shaft produces combined axial motion and cyclically varying rotary motion of the other shaft, which may be utilized for actuating mixers, or for water or vacuum pumps, air compressors, &c. in which the rotary motion may open and close valve ports. Conversely, the axially movable shaft may be reciprocated to produce rotary motion of the crank shaft as in the crank driving gear of a piston engine. The coupling link may be telescopic to enable cyclically varying rotary motion without axial displacement to be obtained for actuating electromagnetic ignition machines &c. As shown, a crank shaft a actuated by a handle d and a slidable shaft g lying in the same plane are connected by a twin coupling link k pivoted at its ends to cross members w, x, the member x being secured to the shaft g whilst the member w is rotatably mounted in the crank arm e thus forming a universal joint. The bearings b, c for the shaft a are carried by a plate n adjustable about a pivotal axis p passing through the intersection of the crank axis v and the shaft axis f, and secured in desired positions by a nut t. If the crank arm e is inclined instead of being at right-angles to the shaft a, the phase relations of the maxima and minima velocities of the shaft g are altered. A universal joint is necessary at each end of the coupling link k if the axes of the shafts a and g are in different parallel planes, but in this case the axis p need not pass through the intersection of the axes f and v.
