Abstract: 1,237,143. Electro-plating apparatus. BURROUGHS CORP. June 4, 1968, No. 26411/68. Heading C7B. A metallic film of uniform thickness and magnetic properties is electro-plated on each side of a disc 36 by mounting the disc within an opening 42 in a plateable holder 34, mounting the holder in an electrolyte solution containing metal ions and generating a uniform electric field normal to the flat surfaces formed by the disc and holder. As shown, a polyester reinforced fibre glass tank 10 has mounted therein anode assemblies 76, 106, porous diaphragms 68, 70 and the holder 34 and disc 36. The disc itself has a central opening 54 which is closed by a plug 56. Electrolyte flows upwardly from an inlet 136 and between the disc 36 and diaphragms 68, 70. Some passes through and some flows over the top of the diaphragms to contact the anode assemblies 76, 106. Electrolyte leaves the anode chambers through ports 24, 26. The holder 34 and disc 36 serve as a cathode. The anode assemblies 76, 106 are adjustably mounted on the tank side walls by screws 82, 111 (and 84, 112), Fig. 2 (not shown) passing through slots in metal cross-bar members 78, 108. The positions of the anode assemblies are adjusted until the current density on opposing plateable surfaces of the disc is everywhere equal. This is recorded by a zero reading on a voltmeter (166) Fig. 5 (not shown). A brass disc 36 may be coated with Ni/Co using anode members composed of 80% Co and 20% Ni and an electrolyte at 45-65‹ C. comprising cobalt sulphate, nickel sulphate, nickel chloride sodium sulphate, boric acid and sulphuric acid to give a pH of between 3À5 and 5À0. The brass disc may have a copper plug 56 and be mounted in a copper holder 34 by copper ring members 48, 50.

Title: Improvements in and relating to cooling beds for rolling mills
IPC: B21B43/02
Filed: 1958-08-19
Abstract: 922,174. Cooling beds. BRIGHTSIDE FOUNDRY & ENGINEERING CO. Ltd., and F. STARKEY. Aug. 18, 1959 [Aug. 19, 1958], No. 26696/58. Class 83 (4). In a cooling bed for a rolling mill having sets of racks 10 and 11, the individual racks of one set being located alternatively with those of the other set, the front ends of the two sets of racks are supported on carrier brackets movable in circular paths by eccentrics which are 180 degrees out of phase and the rear ends of the sets of racks are supported on the free ends of rocker arms which are pivotally connected to the carrier brackets and mounted for limited pivotal and horizontal movement intermediate their ends so that each rack describes a circular movement in the vertical plane. Hot bars received from the mill by rollers 40 are transferred to orificed ramps 41 by a rotating kicker 43 where they slide down to a stop 42 before being raised into the first notch of racks 10 by plungers 44. The racks 10 are supported by beams 12 and 22, the beam 12 being mounted on brackets 14 rotated by eccentrics 15 on a drive shaft 16. The racks 11 are similarly supported by means 13 and 21. The beam 13 being mounted in brackets 19 driven by eccentrics 20. Rocker arms 23, 24 freely supported on a pedestal 29 are pivoted to the brackets 14, 19 so that the vertical component movement of the eccentrics 15, 20 is transmitted to the beams 21, 22. In operation the beams 22 therefore rises and falls with the beam 12 while the beams 13, 21 also rise and fall together, the eccentrics 15, 20 being 180 degrees out of phase. The horizontal component of the eccentric motion is transmitted to beams moving laterally on rollers 25, 26. Batteries of such cooling racks may be joined by spigot and socket engagement at the ends of beams 12, 13, 21, 22 which maintain alignment while minimizing distortion due to expansion. An expansion coupling is also provided in the drive between the several crank-shaft in a battery-type bed. The bars are received from the racks on to a tiltable platform 45 and then pass on to rollers 46 which carry them away.

Abstract: 1,045,346. Percussive tools. H WACKER, and P. WACKER. July 5, 1963 [July 7, 1962], No. 26696/63. Heading B4C.  A ramming apparatus comprises a ramming plate 1 movable in a weight 6 and urged towards the latter by a spring 4, an hydraulic system 11, 12, 13 being provided for tensioning the spring and suddenly releasing the tensioned spring. The plate 1 is carried by a rod 2 forming a piston 2a which is slidable within a cylinder 3 formed in the weight 6, the spring 4 surrounding the cylinder and acting between the weight and a plate 7 adjustably mounted on an extension of the rod 2. The hydraulic system includes a pump 12 and valve 11 attached to the weight, a reservoir 13 for the oil being provided within the weight. In operation, upon actuation of the valve 11, oil is fed under pressure into the cylinder chamber 8 thereby lifting the weight in relation to the piston 2a and so compress the spring. The distance through which the weight is lifted is governed by the hydraulic pressure built up in the chamber 8 the pressure being set by a regulator 16. When the set pressure is reached, the valve is actuated, thereby releasing the pressure so that the plate 1 rapidly moves towards the weight and they both hit the ground together under gravity.

Abstract: 1,043,469. Automatic attitude control. ALBISWERK ZURICH A.G. June 29, 1964 [June 28, 1963], No. 26767/64. Heading G3R. In an error-actuated servo-system at least two error signals having uncorrelated random fluctuations are produced by partly independent measuring units and the smallest error signal is automatically selected for control when the error signals are of the same polarity. In Fig. 2 (not shown), a radar aerial 1, coupled to transmitters 6, 7 operating at different frequencies, makes a conical scan, and associated receivers 8, 9 each produce a pair of D.C. signals corresponding in magnitude and polarity to the magnitude and sense of horizontal and vertical displacement between the axis of the aerial and the direction of a target aircraft. The two horizontal displacement signals are applied to a diode rectifier network 10 which, if the two signals are of opposite polarities, produces no output, but which, if the signals are of the same polarity, applies the smaller of the two to control a follow-up motor 2 eliminating the displacement. A similar diode circuit II eliminates vertical displacement by selecting the smaller of the two vertical displacement signals, if they are of the same polarity, to control a follow-up motor 3. The diode networks, which are described in detail, include a valve amplifier to compensate for attenuation by network resistance.

Title: Improvements in or relating to the production of artificial textile yarns and threads
Filed: 1928-09-19
Abstract: 323,209. British Celanese, Ltd., and Taylor, W. I. Sept. 19, 1928. Yarns and threads.-In the production of yarns and threads, artificial silk or other artificial filaments are collected in masses the filaments of which are irregularly disposed throughout the whole mass, and, from the masses, staple fibres are obtained by a breaking, tearing, or cutting operation, the filaments being preferably first straightened by a teasing, combing or like operation. although the teasing or combing may follow stapling by cutting. The staple fibre so obtained is spun into yarns or threads by the usual wool or cotton spinning operations and the staple may be used alone or mixed with other fibres or doubled as yarn with other yarn composed of or containing different fibres such as wool, cotton, natural silk, or a different type of artificial filament, thus obtaining cross-dyed or differential effects when using dyestuffs for which the mixed filaments or fibres have different affinities. As suitable material for artificial silk and like filaments are mentioned cellulose acetate, formate, propionate, and butyrate, thiocarbamic or alkoxyalkacyl esters of cellulose, methyl, ethyl or benzyl cellulose, and the condensation products of cellulose with glycols or other polyhydric alcohols. Filament masses produced by the process described in Specification 323,221, [Class 2 (ii), Cellulose &c.], are particularly suitable.

Abstract: 835,732. Control of two D.C. motors. BRITISH THOMSON-HOUSTON CO. Ltd. Sept. 18, 1956 [Sept. 22, 1955], No. 27098/55. Class 38 (3). Motors 1, 2 which may drive the top and bottom rolls of a rolling mill, are supplied from Ward Leonard generators 3, 4, and 5, 6, having field windings 8 ... 11 respectively. The bridge circuit formed by the field windings is supplied from a main exciter 14 as well as from a loadbalance exciter 15 having opposing field windings 16, 16<SP>1</SP>, which are energized in accordance with the currents in the respective motor circuits. When the machine 15 is excited by a resultant field due to windings 16, 16<SP>1</SP>, the bridge circuit is unbalanced whereby the motor currents are restored to equality of other predetermined relationship. The machine 14 has a pilot exciter 19 with a control field winding 20, furnishing a basic excitation determined by the setting of master controller 22, and a field winding 21 which is energized in accordance with the difference of voltages respectively derived from the generators 5, 6, and from an exciter 23. A field winding 24 of the machine 23 has its excitation determined by the setting of the master controller. As the voltage in the circuit of motor 2 increases, the voltage obtained from resistor 75 overcomes that derived from exciter 23 until the current in the field winding 21 is reversed and the resultant excitation of the machine 19 provides for operation of the generators at a selected voltage. Field windings 25, 26 of the motors are energized by main exciters 27, 28, having series field windings 29<SP>1</SP>, 30<SP>1</SP>, which are cross-connected. A currentmeasuring reactor 31 is in circuit with a field winding 35 of a pilot exciter 36 for the machines 27, 28.
