Title: Improvements in or relating to grid pasting machines particularly for use in connection with storage battery plates
IPC: H01M4/20
Filed: 1932-08-03
Abstract: 398,328. Pasting accumulator &c. grids. TENNANT, W. J., 111, Hatton Garden, London.-(Monark Battery Co., Inc.; 4556, West Grand Avenue, Chicago, U.S.A.) Aug. 3, 1932, No. 21793. [Class 87 (ii).] A machine for pasting grids such as accumulator plates comprises a frame consisting of standards 10 supporting rods 11 joined by a cross-piece and provided with collars 18 which also support side-plates 16 carrying the bed 17. The sides 16, bed 17, and the apparatus carried by it can be moved bodily without moving the standards 10, for adjusting the tension of the conveyer belt 26, by moving the collars 18 along the rods 11. This can be done by rotating nuts 18a on the threaded ends of the rods. The belt 26 passes over drums 23, 25 rotated by a motor 21. The plate feeding mechanism consists of a platform 57 which supports a stack of plates 36 which are projected one at a time on to the belt 26 by a reciprocating plate 58. A roller 74 holds the plates firmly against the belt and guides them beneath the hopper C which contains the paste. The hopper is supported a short distance above the belt to allow the plate 36 to pass underneath, only the bottom plate of the pile being allowed to pass by reason of a vertically adjustable plate C<1>. Within the hopper C are shafts 37, 45 carrying blades 38, 46 which feed the paste downwardly into the plate below the hopper, the paste being pressed into the plate by rollers 47, 52, the latter rotating rapidly in the opposite direction to that of roller 47 and serving also to polish and finish the upper side of the plate. The plate is held firmly against the roller 52 by a tiltable platen 79 beneath the conveyer belt, a yieldable roller 83 being also situated beneath the belt and the roller 52. A knife 56 removes superfluous paste from the roller 52. To hold the plates in position on the belt a strip of paper is drawn along with the belt from a roll of paper 100. After having been pasted the plates pass beneath a wiper 92 which consists of a rubber strip placed obliquely across the machine and carried by a rod 88 which rocks in brackets 89 and carries an adjustable weight 94. The grids are then conveyed to tracks 97 which engage ears on the plates and cause the plates to swing into a vertical position as they slide on a chain conveyer 96 which removes the plates from the machine. Specification 398,450 is referred to.

Title: Gel fractionator
IPC: G01N1/28
Filed: 1971-04-19
Abstract: 1349482 Obtaining gel samples for analysis W E GILSON and R E GILSON 19 April 1971 [1 April 1970] 22363/71 Heading B1X [Also in Divisions B4-5] A column of gel which may comprise a protein dispersed by electrophoresis in polyacrylamide gel is cut axially and then radially into samples for subsequent analysis, for example by determination of radioactivity, by the intermittent extrusion thereof, by means of a piston 52, from a glass cylinder 12 through an outlet screen 92, e.g. of 80 mesh, which effects the axial cutting, and from the exterior face whereof, after cessation of movement of the piston, the radial cutting is effected by a wire 108 which rotates across the screen exterior face, when the individual samples may fall into containers on a fraction collector. The wire 108 is rotated by a member 102 across the funnel shaped opening of which it is mounted, the rotation being effected by a geared drive 118, 114 from a motor 118. The samples are washed from the face of the screen 92, to drop from an outlet 24 of member 102, by fluid supplied in sequential pulses, e.g. three or four, from a pump 119 and via an annular passage around, and a passage 26 through, the rotating member 102. During extrusion the conical configuration of the upper surface of piston 52 urges the seal 54 outwardly into contact with the cylinder 12 and against the lower end of the sleeve 50 thereby preventing backflow of the gel column. The member 92 may be rotated continuously throughout a pause between intermittent extrusions, permitting complete extrusion from the screen, or may be rotated only briefly for the terminal part of the pause.

Patent GB-424061-A (GB)
Title: Improvements in or relating to the manufacture of chlorinated rubber
IPC: C08C19/14
Filed: 1933-08-11
Abstract: A solution of chlorinated rubber containing about 65 per cent of combined chlorine calculated no the weight of the chlorinated rubber is aged in the presence of free chlorine under conditions approximating to ageing in glass-lined vessels in the dark and without introduction of fresh chlorine after ageing has commenced, and the consequent decrease in viscosity is arrested at a time predetermined in accordance with the logarithmic formula hereinafter stated.  The arrest may be performed (a) by treating the aged solution to isolate solid chlorinated rubber, as by injecting the solution into agitated boiling water, or (b) by removing the free chlorine from the aged solution, as by treatment with a basic substance such as soda ash.  The logarithmic formula is <FORM:0424061/V/1> where V0 and V1 are respectively the initial viscosity and viscosity after time t and k is a constant.  The value of k varies slightly with temperature, but is substantially unaffected by changes in the amount of dissolved chlorine.  Its value at 30 DEG  C. is about 0,017.  Preferably, the ageing is carried out immediately after the chlorination of a solution of the rubber, but may also be applied to a solution of chlorinated rubber, chlorine being passed into the solution for a short time prior to the ageing process.  An example is given in which it is shown that having taken preliminary viscosity readings of a solution ageing in the dark &c. a straight line graph can be drawn from which the ageing time necessary for a certain desired viscosity can be deduced, this time agreeing closely with the time actually found necessary.  Specifications 400,898 and 402,454 are referred to.

Title: Walking Beam Furnace
IPC: F27B9/20
Filed: 1967-05-15
Abstract: 1,156,273. Walking beam conveyers. SALEM.BROSIUS (CANADA) Ltd. 15 May, 1967 [30 Jan., 1967], No. 22515/67. Heading B8A. [Also in Divisions F4 and H1] A walking beam assembly is situated between pairs of stationary stock supporting piers 25 and comprises refractory supports 29, 30 secured through water-cooled housings 33, 34 and deck plate 35 to structural steel beams 39, 40. These beams are formed in sections interconnected by links 36 to facilitate their replacement. The beams 39, 40 are secured to wear plates 43, 44 and are provided with shield plates 46, 47 which cooperate with water - filled troughs 48, 49 into which further shield plates 52, 53 from the adjacent stationary piers 25 also dip, to seal off the interior of a furnace in which the assembly is located from the atmosphere. Movement of the walking beam is derived from a reciprocating rod 62 driven from hydraulic or pneumatic lift cylinder 67. Movement of rod 62 towards the entrance 12 of the furnace causes crank arms 54, 55 to pivot about blocks (58, 59, Fig. 7, not shown) secured to the furnace structural support beams 50, 51 to so cause rotation of rollers 56, 57 which engage the undersurface of wear plates 43, 44. On pivoting of the crank arms 54, 55 the supports 29, 30 are thereby lifted upwardly above the level of stationary support piers 25 to support the stock S. In the lifted position, the wear plates 43, 44 and beams 39, 40 and thus also the stock S are then advanced along the rollers 56, 57 one step by the action of hydraulic or pneumatic traverse cylinder 70 transmitted through piston 74. On the reverse stroke of rod 62 the stock is lowered back on to stationary piers 25, and then on the reverse stroke of the piston 74 the beams 39 40 are withdrawn back towards the entrance end of the furnace in preparation for the next walking step. This construction allows the beams to move the stock in either the forward or the reverse directions. The stroke of each walking step may be controlled either manually or in a programmed sequence by means of a variable limit switching controller 75 (see Division H1 and Figs. 12-14) which controls an electric motor (not shown), supplying fluid to the traverse cylinder 70.
Patent GB-698422-A (GB)
Title: An improved method of purifying raw phenols containing neutral oils
IPC: C07C37/86
Filed: 1950-09-14
Abstract: A method for the purification of raw phenols by extraction of neutral oils (hydrocarbons) which render them impure is characterized in that the raw phenols are hydrated to monohydrates by adding substantially one mol. of water per mol. of phenol in the mixture to be treated and the neutral oils are removed by extraction with petrol of aliphatic character which is free from aromatic hydrocarbons and boils between 50 and 100 DEG  C. In examples: (1) raw phenol containing 2 per cent neutral oils is converted to its monohydrate by adding 17 per cent of water and the oil then removed by five successive extractions with aliphatic hydrocarbons, boiling-point 50-100 DEG  C.; (2) a similar process is carried out continuously passing the phenol monohydrate and aliphatic hydrocarbons in counter-current through an extraction column, phenol monohydrate being introduced into the top of the column and the petrol into the bottom thereof.  The hydrocarbon extract is distilled and the aliphatic hydrocarbon returned to the extraction process.  From the residue after distillation the phenols are extracted and the phenolates obtained are returned to the phenol removal process.

Abstract: 600,959. Converting ; automatic-control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 3, 1945, No. 22615. Convention date, Sept. 2, 1944. [Classes 38 (ii) and 38 (iv)] A control system for a converting arrangement including at least one pair of alternately conducting valves of the make-alive type, comprises an impulsing circuit having a natural frequency of resonance less than the frequency of the current supplied to it. The ignition electrodes 17 of each pair of valves 13 receive impulses produced by a saturable inductance 26 from a circuit including reactance 21 and capacitor 20 which has a resonant frequency of less, preferably by about 25 per cent than the frequency of the supply to the circuit through phase-changer 30 and transformer 18 from the main supply 10 to the converters. The threelegged reactor 21 has a control winding 22, preferably D.C. used to vary the value of the reactance 21 and thus change the phase of the . impulses supplied to the ignition electrodes. The value of control current is altered by a variable resistance 27 operated by a coil 28 connected across the output circuit 11 of the converter. Resistance 29 provides manual setting of the control, and phase-changer 30 provides a wider range of phase-shift.
