Abstract: 1,079,080. Producing metal articles etc.; power hammers &c. E. DURRWACHTER, and E. BOSCH, [trading as DR. EUGEN DURRWACHTER DODUCO]. May 16, 1966 [May 15, 1965 (2)], No. 21603/66. Headings B3A and B3H. In a machine formaking- bimetal contact rivets from wires 4, 5 and having a fixed die 10 with a counterbored bore 8 in which the contact is formed, a movable die 2 moves laterally from a first position (Fig. 1) under the wire 4 through an intermediate position under the wire 5 (Fig. 2) to a second position as shown. When in the first position (Fig. 1) a section of wire (4a) is fed into the bore of the movable die 2, and this section is sheared off during the transfer to the intermediate position (Fig. 2) where a section (5a) of the wire is fed into the bore in the die 2, abutting the section (4a). When the die 2 is moved to the second position under the bore 8 the section (5a, Fig. 3) is sheared off the wire 5. A pin 3 is then moved upwards by a stem (9, Fig. 3), driving the two sections (4a, 5a) into the bore 8 where they abut a pin 6 and are partially formed and welded by the force exerted by the pin 3. The die 2 is then returned to the first position and a heading tool (12, Fig. 5) brought under the partially formed contact. The contact is then finished by the heading tool (12) and ejected by the pin 6. The movement of the die 2 is provided by mounting it on an arm (13, Fig. 6) of a bell-crank lever which is moved by a cam (16). The wire may be a noble metal such as silver and the wire 5 of copper.

Patent GB-233649-A (GB)
Title: Improved manufacture of polymerized styrol and its homologues
IPC: C08F240/00
Filed: 1924-09-15
Abstract: A vitreous product which can be cut with a knife is prepared by polymerizing a mixture containing styrolene or its homologues to obtain the ordinary resinous polymerization product, depolymerizing this product by dry distillation, purifying the product and again polymerizing.  Mixtures containing styrolene &c. may be prepared as described in Specification 232,909 or by the cracking of petroleum oils or by collecting fractions boiling at 130-160 DEG  C. obtained in distilling drip oil or holder oil (waste products obtained in carburetting water gas), or crude solvent naphtha.  The polymerization is effected by heating in an autoclave or in a vessel with a reflux condenser for 14-48 hours at 140-180 DEG  C.  The resinous product is purified by steam or heat treatment and is depolymerized by being distilled at 350-500 DEG  C.  The distillate of styrolene and distyrolene is treated with steam.  Trinitrobenzene may be added to check polymerization.  The styrolene, which is carried over as vapour, may be diluted with a solvent such as xylene, and is polymerized, preferably in a solution containing more than 40 per cent styrolene by heating to 135-140 DEG  C. in a vessel fitted with a reflux condenser.  The vitreous product is obtained by evaporation of the solution or by precipitation with alcohol. Similar vitreous products may be obtained from o-methylstyrolene, p-methylstyrolene, symmetrical diomethylstryolene and ethylstryolene. The Specification as open to inspection under Sect. 91 (3) (a) describes also that a homogeneous mass of polymerized styrolene or its homologues is obtained by adding styrolene or its homologues to a mass of pieces or powder of the polymer, and polymerizing by heating to 180 DEG  C. for 3 hours, or for a shorter time under pressure.  A powdered polymerized product may be obtained by emulsifying styrolene or its homologues with ammonia solution and oleic, stearic, palmitic, &c. acids.  The emulsion is heated to 140 DEG  C. for 12-24 hours and may be mixed with gelatine, gum arabic, agar agar, starch, &c.  The polymerized product is precipitated by addition of methyl or ethyl alcohol, acetone, sulphuric or acetic acid, barium chloride, or any agent which coagulates rubber latex.  The product is dried and may be mixed with pigments such as zinc oxide, cadmium or mercury sulphide and compressed in a mould.  During purification of styrolene by distillation quinone may be added to retard polymerization. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the packaging of articles
IPC: B65B61/18
Filed: 1934-07-26
Abstract: 438,076. Wrapping-machines; packages. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Ivers-Lee Co. ; Newark, New Jersey, U.S.A.) July 26, 1934, No. 21817. [Class 94 (i)] In wrapping tablets, buttons, and other small articles in coated regenerated cellulosic sheet material, heat is applied to a portion of the wrapping to fuse the coating, and at the same time to oxidize and render brittle the cellulosic material to facilitate access to the contents by tearing. The articles may be packed in strip form as shown in Figs. 2 and 3, the strip being manufactured as shown in Fig. 6. A band 1 of cellulosic material, and an insert 14, which may bear suitable directions, with tablets 2 spaced thereon, is fed towards a heated sealing roller 3 and a platen 4, which form it into a tube with a longitudinal seam 6, Fig. 4. The tube then passes between rollers 8 having heated crimping or pressing dies which unite the walls of the tube between the tablets and form a closure or bond in which the material is rendered brittle. To further promote ease of separation of the packages, the adhering portions are weakened by cutting out portions of the edges as at 10, 11, Fig. 2, by dies 13 co-operating with recesses 12. U.S.A. Specification 1,925,509 is referred to.

Title: Improvements in or relating to the filling of cylindrical tubes with a powdered material
IPC: B65B1/24
Filed: 1954-07-28
Abstract: 760,176. Cables. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. July 28, 1954 [July 29, 1953], No. 22100/54. Class 36. Apparatus for filling a cable sheath 1 with powdered insulating material comprises a reciprocating tamper 3 having a channel therethrough and a reciprocating valve 6 which closes the channel during part of the movement of the tamper, the movements of the tamper and the valve being synchronized, and the channel being opened and closed at points of movement of the tamper equally disposed on either side of its withdrawn position. The tamper 3 may comprise a hollow cylinder carrying a seating 5 on its lower end against which the valve 6 may bear. The valve is connected to a control tube 4 and has wings 7 centring it in the tamper 3. These parts are located within a cable sheath 1 and about a conductor 2. A reciprocating motion is applied to the tamper by means of an eccentric 8 driven by motor 18. Tube 4 is associated with a cross-piece 9 which is pushed upwardly by spring 10 bearing on stop 11 carried by the tamper. The upward movement of the cross-piece 9 is limited by adjustable screws 12 contacting stop 13. Cable members 1, 2 rest on a base 15 through a plate 22 and springs 21. A percussion device 14 is provided on the base, which is suspended from cables 23 which are tensioned by counterweights 16, the mass of which is such that they tend to move the base upwardly. Ratchet-wheels 17 prevent this upward movement but permit the base to move downwards. As the tamper moves upwards the valve 6 remains against seating 5 until screws 12 contact stop 13, so that during further upward movement of the tamper the valve is stationary, permitting powder, fed to tube 20, to enter the sheath 1. As the tamper moves down it meets the valve and carries it down to tamp the powder, which is also compacted by the percussion device 14. When the stress on the tamper is sufficient to overcome the action of counterweights 16, the base 15 and cable members 1, 2 are pushed downwardly. The valve may be modified to permit the passage of more than one conductor, and the apparatus may be modified to permit the cable to be mounted horizontally or on an incline. Specification 669,780 is referred to.

Title: Improvements in or relating to magnetic members and material and to coating compositions for use therewith
IPC: C03C4/00
Filed: 1944-11-09
Abstract: A composition for application to ferrous members which are to be heat treated in contact with each other for the manufacture of magnetic cores, the composition serving to prevent the members welding together and to react during heating to form a tenacious insulating coating, comprises a minor proportion, e.g., 2-20 per cent., of barium, beryllium, zirconium, calcium, or magnesium meta-silicate and a major proportion of magnesia.  The ferrous material is preferably a silicon-iron material which is heated to 1,000-1,250 DEG C. to develop magnetic characteristics.  Ordinary magnesia may be used as a basis, but if it be particularly pure 2-5 per cent. of an alkaline earth oxidizing-agent such as calcium or barium oxide may be added. The magnesia and the silicate are finely powdered and are stirred into water, acetone, or ethyl alcohol, the mixture being then applied by roll coating or spraying.  The sheet material is dried at 200-300 DEG C. and is then placed in an annealing furnace at 700-1,250 DEG C. in an atmosphere of hydrogen.

Title: Improvements in and relating to apparatus for controlling the ratio of the flow of two fluids
IPC: G05D11/13
Filed: 1947-08-08
Abstract: 663,828. Fluid-pressure servomotor control system. ASKANIA REGULATOR CO. Aug. 8, 1947 [June 19, 1940], No. 22137/47. Class 135. Apparatus for maintaining constant the ratio by weight of the flow of a fluid or fluids in two conduits, comprising a flow regulator which is influenced both by changes in the ratio of the volumetric rate of flow and by the output of a device responsive to the temperature in the two conduits. As shown in Fig. 1, the ratio of rates of flow in conduits 1, 2 is kept constant by a known type of ratio regulator 6. Any variations in temperature causing density variations are detected by temperature sensitive devices 13, 14, which form two arms of a balanced Wheatstone bridge (Fig. 2) thereby unbalancing the bridge. Restoration of the balance is effected by manually rotating a knob 16 adjusting a slide on a potentiometer 22 which forms the other two arms.of the bridge. Rotation of the knob 16 causes, through gears 18, 19 and cam 12, a readjustment of the ratio regulator 6 to alter the ratio of rates of flow thereby, compensating for the density variation and thus maintaining a constant ratio of weight flow. Alternatively a pointer on the shaft which drives gear 19 may be adjusted to be kept in alignment with a pointer rotatably mounted on the shaft and giving the direct differential reading obtained from a differential temperature thermometer (Fig. 6, not shown). Specifications 224,655 [Class 135] and 502,820 are referred to. In the Specification as open to inspection under Sect. 91 the output of the bridge circuit may cause rotation of a motor rotating the gear 19 for automatic control. Fig. 7 (Cancelled) (not shown). This subject-matter does not appear in the Specification as accepted.

IPC: B41B5/02
Filed: 1920-07-27
Abstract: 168,754. Lanston Monotype' Corporation, Ltd., (Lanston. MonotypeMachine Co.). July 27, 1920. Matrices for singletype composing and casting machines. In the manufacture of cellular matrices having side grooves for engaging combs in a matrix case, the formation of burrs in the grooves is prevented by cutting at the side corners preparatory serrated bevels. As applied to a matrix having, as described in Specification 4726/05, wide grooves 5 and narrow grooves 6, the side corners are formed, before cutting the grooves, with deep serrated bevels 4 and shallower plain bevels 3. In cutting the grooves, the bevels 3 are reduced to small faces 3<1>, and the serrated bevels 4 are reduced finally to a series of pairs of small triangular faces 4' meeting in points 4<a>, the serrations thus reducing the area of attachment of the chips and causing them to break readily. Chips formed at the faces 3<1>, being accessible, can be readily removed by rubbing the matrix longitudinally on a file. The points 4<x> lie in the line of intersection of the grooves, the pointed parts thus prolonging the grooves and causing them to have the maximum bearing on the combs. Angular faces 10, 11 are cut at the ends of the grooves, to form guides for the combs and prevent the formation of burrs. The bevelling and grooving-machines described in Specifications 13478/09 and 8990/11, [both in Class 83 (iii), Metals, Cutting], respectively may beemployed for the above-described operations.

Patent GB-666206-A (GB)
Title: An improved process for neutralizing capillary active, sulphonated products
IPC: C11D1/00
Filed: 1947-08-12
Abstract: A process for neutralizing sulphonated mono-or diglycerides of higher fatty acids having at least 8 carbon atoms in the molecule, is characterized by adding the crude sulphonation product to an inert organic solvent for the sulphonation product in which solvent there is suspended a neutralizing agent slightly soluble or insoluble in the said solvent.  The crude sulphonation product is applied to the suspension of the neutralizing agent in the form of a thin jet.  Any organic solvent may be used which does not react in an undesirable way with the sulphonating agent under the neutralizing conditions, for example aliphatic alcohols such as methyl alcohol, ethyl alcohol, propyl alcohols, butyl alcohols and amyl alcohols, polyhydric aliphatic alcohols such as ethylene glycol and glycerols, ketones such as acetone and methyl ethyl ketone, ethers such as dimethyl ether, diethyl ether and diisopropyl ether, but ethyl and propyl alcohols are preferred. Hydrocarbons and halogenated hydrocarbons are suitable solvents but less satisfactory than the alcohols.  Mixtures of solvents may be used.  The organic solvents may contain water or water may be emulsified with water-immiscible organic solvents.  As neutralizing agents may be used any substance of alkaline reaction and only slightly soluble or insoluble in the organic solvent, examples of which are the hydroxides such as calcium and magnesium hydroxide, oxides such as calcium and magnesium oxides and salts having an alkaline reaction such as phosphates or sulphites and carbonates and/or bicarbonates such as sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, ammonium carbonate and ammonium bicarbonate.  Preferably the neutralized sulphonated product should be soluble in the organic solvent and the neutralized sulphonated product should be precipitated together with unused neutralizing agent.  The sulphonated product may be obtained from the solution by evaporation of the solvent after filtration though the latter is not essential.  In the example a mixture of sulphonated coconut oil monoglycerides is poured as a thin jet into a suspension of sodium bicarbonate in ethanol.  At approximately 25 DEG C. water formed by the neutralization will be absorbed by the sodium sulphate produced, which is insoluble in the alcohol.
