Patent GB-762090-A (GB)
Title: Improvements in or relating to mechanical loading apparatus employing grab forks
IPC: A01C3/04
Filed: 1953-05-19
Abstract: 762,090. Grabbing machines. BONNEL, H. A. May 19, 1953 [May 19, 1952; March 3, 1953], No. 14070/53. Classes 78 (3) and 78 (4). A grab fork which can be locked open or closed is mounted at the end of a luffing and slewing jib 1, Fig. 1. As illustrated the jib 1 is luffed by a double-acting hydraulic ram and is carried by a column 2 which slews on the chassis 4 of a semi-trailer. The grab comprises tines 8 carried by frames 7 pivoted to a rod 6 sliding in a tube 5 to which the frames 7 are connected by chains 9. When the grab, in its open condition, is pressed down upon the material a flat portion 15, Fig. 3, of the rod 6 rises in the tube 5 until a flange 10 abuts the tube; during this motion a roller 16 carried by the member 15 pushes aside a sector 13 pivoted to the tube 5 and extending through a slot in its wall. A spring 17 subsequently returns the sector 13, locking the roller 16 in its upper position so that when the jib 1 is raised the grab fork closes on its load. To release the load a cable secured to a lever 18 carried by the sector 13 is pulled to cause the sector to release the roller 16. A further roller such as 16 may be provided for locking the grab fork in a partially closed condition. In an alternative construction of grab each set of tines is pivoted at one end of a transverse head at the lower end of the column 6 and the chains 9 are replaced by arms on the jaws connected by links to the tube 5 so that the grab fork is opened and closed by movement of the member 15. The jib may be luffed by a cable (Fig. 2, not shown), wound on a drum carried by the mast and secured at its ends to points on the jib spaced on opposite sides of the luffing pivot.
Patent GB-567864-A (GB)
Title: Improvements in or relating to telecommunication exchange systems
IPC: H04Q3/00
Filed: 1943-08-31
Abstract: 567,864. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., BRAY, F. H., and BROWN, L. R. Aug. 31, 1943, No. 14181. [Class 40 (iv)] In a call finder system somewhat like that described in Specification 541,768, a cold-cathode tube TA coupled by a transformer TRA to the common start circuit responds to the initiation of a call, and a second common cold-cathode tube TB coupled by a transformer TRB to the test circuit of the finder responds when the calling line is found. The resistances R1, R2, R3 associated with each line are each 10,000 ohms, and the closure of the loop reduces the negative potential on the test wire from the nominal 50 volts to about 17 volts. On leaky lines, however, the normal potential may be as low as 25 volts, and, therefore, the test wiper is connected to a negative potential of 25 volts to avoid any current flow from such non-calling lines, while a rectifier MRB prevents the flow of current from non-calling lines having a greater negative potential on their test wires. This feature forms the subject-matter of Specification 567,874. When the finder switches through, a fresh idle finder is selected by the allotter AL, and the relapse of relay C initiates a search by this finder before relay STR falls back in case two or more calls were made concurrently, as the start relay ST is released by relay FR when the first calling line is found. A timing condenser C1 and cold-cathode tube TC provide for the operation of FR and release of ST if a calling line has not been found within a certain time. A single tube may be used in place of the tubes TA, TB with means for switching it from the start circuit to the test circuit, as in Specification 541,768. Specification 409,670 also is referred to.

Abstract: 849,733. Linear-dimension gauges. CURTIS, T. May 2, 1958 [May 3, 1957], No. 14182/57. Class 106 (2). A gauge comprises two coaxial plates 1, 2 mounted for relative angular adjustment, and having radial cut-outs 6, 7 formed with complemental measuring jaws 8, 9 and arcuate scales 14, 15 for reading the setting of the jaws. The jaws 8, 9 are each thickened axially so providing opposed gauging surfaces, and the back faces 10 of the jaws abut the other edges 11, 13 of the cut-outs 6, 7 in the fully opened position to act as stops. Holes 16, 17 are formed in the plates 1, 2 and by use of a locking pin passing through a pair of holes, the plates can be held in any adjusted position (to within <SP>1</SP>/ 64  inch in the embodiment shown). In a modification, the jaw 8 is provided with an auxiliary jaw which can be adjusted relatively to the jaw 8 by a cam mechanism, thus providing finer measurements than are possible from the scales 14, 15. In a further embodiment, the plates 1, 2 are replaced by C-shaped plates, thus allowing objects to be measured which reach past the centre of revolution. In this case one plate is guided for angular movement in guides mounted on the other.

Filed: 1960-04-22
Abstract: 895,606. Coated fabrics; waxed paper. SIEMENS & HALSKE A.G. April 22, 1960 [April 23, 1959], No. 14227/60. Classes 96 and 140. A carrier strip is coated by a method which includes the step of impregnating or coating the strip, which may be of paper, with wax to form a layer thereon, softening the wax layer by heating, transporting the softened layer past a smooth surface of a continuously cooled cylinder adapted to be rotated about its axis and maintaining the wax layer in contact with the smooth surface for a period long enough to cause the wax layer to solidify. The impregnated or coated carrier strip 4 may be wound from a first roll 3 in a housing 1 in which may also be mounted a heating element 2 which may heat the wax layer to a temperature above that at which it melts, transported past cylinder 5 which may be water- or air-cooled, prior to being wound into roll 9. The wax may be a mixture of paraffin wax and polyethylene together with polyisobutylene. A layer, which may be 6 microns thick, of an electrically insulating varnish may be deposited on to the solidified surface of the wax layer. A metallic coating may be vapour deposited on to the varnish surface and these two materials may together be readily peeled away from the wax coating.

Patent GB-385202-A (GB)
Title: Manufacture of dyestuffs of the anthraquinone series
IPC: C09B1/32
Filed: 1932-05-20
Abstract: Aminoanthraquinone derivatives which are dyes for cellulose esters are prepared by heating with a halogenhydrin an anthraquinone compound which contains an -NH2-group or an -NH-alkyl-group in the 1-position and an -NH-phenyl-NH2-group in 4-position, in the presence of an acid binding agent.  The process is advantageously carried out in the presence of a solvent or diluent or with an excess of halogenhydrin (which term does not include epichlorhydrin), which can act as a diluent.  In some cases both primary amino groups react whereas in others only the aminophenylamino group enters into reaction according to the duration of the reaction. The products are soluble in organic solvents and have good affinity for acetate silk, particularly those reaction products of ethylenechlorhydrin and 1-amino- or 1 - methylamino - 4 - aminophenylaminoanthraquinones.  In examples, (1) 1-amino-4-p<1>-aminophenylaminoanthraquinone is boiled with excess of ethylenechlorhydrin and sodium acetate for half an hour; the product dyes intense steel-blue tints on acetate silk; by boiling for 8 hours a product dyeing acetate silk more greenish-blue tints is obtained; (2)1-methylamino-4-p<1> aminophenylaminoanthraquinone in the form of a paste is boiled for half an hour with ethylenechlorhydrin and potassium acetate, or alternatively heating is conducted in an autoclave for five hours, to give a product dyeing intense green shades on acetate silk; (3) 1-amino - 2 - methyl - 4 - p<1> - aminophenylaminoanthraquinone is boiled for half an hour with ethylenechlorhydrin and sodium acetate to give a grey-blue dye for acetate silk.  Ethylene-chlorhydrin may be replaced by propylenechlorhydrin in the above examples. Specification 275,636, [Class 2 (iii), Dyes &c.], is referred to. The Specification as open to inspection under Sect. 91 relates to the treatment with a halogenhydrin of an anthraquinone compound which contains an -NH2-group or an -NH-alkyl-group in an a - position and an -NH-aryl-NH2-group in at least one other a - position, in presence of an acid-binding agent.  The following additional examples are also given: (4) 1-amino - 4 - (4<1>aminodiphenyl - 4<11> - amino)-anthraquinone is reacted with ethylenechlorhydrin in presence of potassium acetate to give a blue dye for acetate silk; (5) 1-methylamino - 4 - (4<1> - aminodiphenyl - 4<11> - amino)-anthraquinone reacted in the same way gives a blue-green dye for acetate silk; (6) 1 : 5-diamino - 4 : 8 - di - (p<1> - aminophenylamino)-anthraquinone is boiled with ethylenechlorhydrin and sodium acetate to give a greenish-blue dye for acetate silk.; (7) 1-amino-5-p<1>-aminophenylaminoanthraquinone is boiled for 5 hours with ethylenechlorhydrin and sodium acetate to give a brown-red dye for acetate silk.  This subject-matter does not appear in the Specification as accepted.
