Abstract: 1,014,126. Bending wire. STAPLING MACHINES CO. Aug. 17, 1964 [Aug. 16, 1963] No.33580/6,4. Heading B3E. A machine for forming an eye at each end of a wire binder on wirebound box components comprises supporting means for a box component on which component an intermediately positioned wire is secured with portions of the wire extending beyond the edges of the component, said extending portions of the wire being positioned by guide means and being bent into eyes by bending means. Box components W, e.g. end units comprising slats 31, Fig. 13, with a wire binder 33 stapled at 35 thereto having projecting ends 39, are fed from a conveyer 339 on to feed belts 16 which carry them into the bite between the belts 16 and cooperating upper belts 32. The components are held at the entry by a finger 86 which is covered to allow the component to be fed, the entry end of the belts 32 also being lowered. At the same time fingers 300 are raised to allow the completed work to be carried from the machine. Switch means 340, 342'operated by the incoming work W operates time-delay means to cause the fingers 300 to descend into the path of the work and the finger 86 to rise to stop the succeeding work and the entry end of belts 32 to rise out of engagement with the succeeding work W held by the finger 86. By the time the work reaches the fingers 300 a table 152, 146, 148, 150, carrying bending means for the wire ends 39, is raised by cam means 108 to the work W. Means 116 on the cam 108 then starts the operation of units U1, U2 positioned above the table, to cause cutters 264, 306 to descend to trim the wire ends 39 to the correct lengths, means 302, 314 holding the wire during cut-off. Prior to the severing operation the wire ends 39 are positioned by V-slotted members 202, Figs. 8, 9 (not shown), carried by the table, co-operating with V-slotted members 286 and 324 of the units U1, U2, in the end bending means. A spring pin 330 holds the work W during severing and bending. After severing the bending means is actuated to form eyes 87 on the wire ends 39. Each end 39 is bent by a tool 200, Figs. 10, 11, carried by a rotated sleeve 188, about a fixed pin 198 slightly offcentre of the axis of rotation of the sleeve 188. The sleeves 188 are rotated by gears 154, 178 turned by connecting rods 162 and 174 driven from a rocking drive member 160. The eyes 87 are formed against the same side of the wire 33. The right-hand bending means is adjustable towards the left-hand bending means.

Patent GB-491948-A (GB)
Title: Process for the production of hard resistant surfaces on metals
IPC: C23C16/32
Filed: 1936-12-09
Abstract: A hard resistant surface consisting of a carbide such as tungsten or boron carbide is formed on metals, e.g. iron, steel, or light metals, by a method involving the decomposition of the corresponding carbonyl.  The object to be coated may be placed in a vacuum or an indifferent atmosphere, the carbonyl introduced, and the object heated to a temperature considerably higher than the decomposition temperature of the carbonyl to cause deposition of the carbide. Alternatively the carbonyl can be introduced in solution in an organic solvent, e.g. benzene, which evaporates when the object is heated.  The carbonyl decomposes at a comparatively low temperature, e.g. 300 DEG  C. in the case of tungsten, and the tungsten is converted into carbide by the benzene vapour at above 800 DEG  C.  In another method a layer of tungsten is formed on the object by decomposition of the carbonyl, and this is then heated in a reducing carbon-containing atmosphere, e.g. carbon monoxide or a mixture of carbon monoxide and benzene vapour, to a temperature between 970 and 1300 DEG  C.

Title: Improvements in apparatus for stripping sprouts from brussels sprout plants
IPC: A23N15/01
Filed: 1966-07-28
Abstract: 1,148,606. Brussels sprouts stripping device. UNILEVER Ltd. 28 July, 1966 [30 July, 1965; 13 June, 1966], No. 33907/66. Heading A4C. Apparatus for removing sprouts from a Brussels sprouts plant comprises a cutting head which is rotatable about a central axis along which the stalk of the plant can be passed and which includes a plurality of cutting assemblies movable towards and away from said central axis, each cutting assembly comprising a rotary cutter arranged to rotate about an axis extending radially from said central axis. In the embodiment of Fig. 1, Three rotary cutters 22 are provided mounted on a rotating plate 8. The cutters 22 are driven by bevelled pinions 23 running on a fixed bevelled gear wheel (24) and are slidably journalled in a ring 15 mounted on plate 8. The outer ends of all the shafts 21 carrying cutters 22 are linked together by members 25 to 35 so that the cutters are maintained equidistant from the axis of rotation of plate 8 to centre the stem. The geometry of the linkage and the dimensions of springs 37 abutting stops 40 and of centrifugal weights 36 is such that, at the operating speed of rotation, the inward pressure exerted on the stalk by cutters 22 is independent of the diameter of the stalk. In operation, the head is first rotated at a higher speed than this to move the cutters to their outermost positions while the stalk is inserted and then reduced to a predetermined value for the cutting operation. As shown in Fig. 3, each cutter comprises a conical miller cutter 22 to trim the sprouts of their stalks carrying at its base a milled cutter rim 43 to strip the butts off the stalk and having a spherical cap 44 resting against the stalk. In second and third embodiments (Figs. 5 and 6, and 7 to 9, respectively, not shown) each of 2 or 3 rotary trimmer cutters has its own pneumatic motor mounted on the rotating head. Separate, non-rotary stripping cutters are provided and connected by linkages so that the radial distance between the stripping cutters and the central axis varies in proportion to the radial distance between the trimming cutters and the central axis. In the aforesaid second embodiment, the cutters are moved away from the axis of rotation by air-operated cylinders for insertion of the stalk and then pressed inwardly against the stalk by springs on release of the air pressure. In the third embodiment the rotary cutters are maintained in the cutting position by means of an air cylinder and tilted away from this by means of a spring to form a funnel shaped opening for insertion of the stalk on release of the air pressure.

Abstract: 472, 111. Directive wireless signalling. HOOVEN, F. J. Dec. 14, 1935, No. 34710. [Class 40 (v)] Signals received on a frame aerial 10, fixed in the homing position on an aeroplane, are combined with those picked up by a non- directive aerial 12, to give a visual indication in a balanced galvanometer 36 of the course being flown. The directive and non-directive aerials are coupled to separate amplifiers 16, 17, and the output from the valve 16 is fed across the coil 27 in phase-opposition to two rectifiers 37, 38, so that the galvanometer needle remains at zero so long as the craft is travelling directly towards the transmitter beacon. The output from the valve 17 is fed from a coil 33 to the centre tapping on the coil 27 so that it is applied to the rectifiers 37, 38 in phase. When the craft yaws to one side or other, the indicator reading is independent of the characteristics of the valves used in the separate amplifiers. The non-directive signals are also supplied to a pair of headphones 48 through a separate amplifier 47. The signals may be heterodyned by a local oscillator symmetrically coupled to each aerial input. Automatic volume control can be applied from the grid current of the detector 47, in which case an ammeter is inserted in the output circuit of the last non- directive amplifier-valve to give the pilot an approximate indication of his distance from the transmitting beacon.

Abstract: 1,129,554. Dinuclear bridged transition metal complexes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 2 Aug., 1966 [13 Aug., 1965], No. 34740/65. Heading C2C. [Also in Division C5] Novel dinuclear bridged transition metal organic complexes in which the transition metals are different and are selected from Groups VIA, VITA, VIII and IB of the Periodic Table and in which the bridging ligands are univalent with respect to one of the metal atoms and do not incorporate chelating ligands and in which other ligands are present as required to satisfy the co-ordinating numbers and valencies of the transition metals are prepared by reacting a compound or complex of one transition metal with a compound or complex of a different transition metal with or without additional ligand forming reactants. In one method a complex of one transition metal containing halide and substituted phosphine ligands is reacted with a halogen-containing complex of a second transition metal, alternatively the carbonyls of two different transition metals may be reacted with an organic phosphine e.g. diphenyl phosphine or tetramethyl diphosphine, to form a phosphido bridged compound, or two different metal salts of a single organic acid may be reacted with the same free organic acid which forms bridging ligands. The products so formed may also be reacted with further ligand forming reagents to bring about ligand exchange e.g. the halogen bridges of ÁÁ<SP>1</SP>-dihaloplatinum palladium complexes may be replaced by diphenylphosphido bridges by treatment with diphenylphosphine. Non- bridging ligands may also be replaced by such means. The reaction may be carried out in an inert solvent. An inert atmosphere and elevated temperatures and pressures may also be used. Specified transition metals are Pt, Pd, W, Cr, Mo, Fe and Cu. Specified bridging ligands are chloride, bromide, sulphide, thiocyanate, acetate, propionate, benzoate, phosphido and groups containing Se, As or Sb. The complexes are useful as catalysts, in hydrogenation, carbonylation and oxidation reactions, e.g. the hydrogenation of alkynes and alkenes (see Division C5).
