Abstract: 621,739. Rotary offset machines. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Nov. 6, 1945, No. 29595. Convention date, Jan. 17. [Class 100 (ii)] A cylinder 20 carries a master sheet 22 transferring to an offset roller 30 coacting with an impression roller 40 carried by a shaft 41 eccentrically mounted in a carrier 42 spring-pressed towards the roller 30, a second spring 136 being provided for turning the shaft 41 in its carrier 42 to separate the roller 40 from the roller 30, rotation of the shaft being normally restrained by a latch 132 controlled by a paper-detector, and an adjustable stop 49 being provided which is set so as to limit the movement of the carrier, thereby controlling the printing pressure, and also to ensure that on release of the latch the rollers 40 and 30 are separated. The carrier 42 is in the form of a yoke, and two stops 49 are provided each consisting of a nut on a screw 48 anchored to the yoke at 45. The nuts are pressed towards a cross-bar 46 by springs 44, the tension of which is adjustable. The spring 136 acts on a rod 135 connected to a plate 130 which is fixed to the shaft 41 and has a shoulder 131 engaging the latch 132, whereby the plate and therefore the roller 40 are held in normal positions. A detector 141 tests for the presence of sheets between feed rollers 101, 102 and acts through a lever 142 and link 144 to release the latch 132 if no sheet is present. The plate 130 is returned to normal position after a release, by a pawl 148 carried by a rocking arm 72; the pawl also turns the plate slightly each cycle of operation of the machine to relieve the pressure on the latch 132. The Specification also describes mechanisms (a) for controlling the movement of the offset roller and the feed of sheets, and (b) for applying ink and ink-repellent, forming the subject-matter of Specifications 621,774 and 621,775 respectively. A master sheet may be attached to the cylinder 20 as in Specification 499,809, ink and ink-repellent ductor rollers may be actuated as in Specification 526,324, a hand-lever for controlling the application of ink, repellent, or both, may be provided as in Specification 499,810, and the offset roller may have a sheet-gripper to which sheets are guided, as in Specification 499,800. Inking-apparatus. To avoid applying fresh ink to the cylinder 20 when no sheet is fed, an arm 150, Fig. 3, which is slotted at 151 to receive a pin 79 on a pawl 77 normally rotating a duct roller and is connected to the arm 135, moves to the right when the roller 40 is tripped, whereby the pin 79 instead of riding freely in the slot 151 engages the end thereof, whereupon the pawl 77 is tripped and the duct-roller is no longer rotated.

Title: Improvements relating to the making of metal or other wool from a strip
IPC: B23P17/06
Filed: 1956-10-01
Abstract: 839,958. Making 'metal wool. FIELD, C. Oct. 1, 1956 [Oct. 4, 1955], No. 29904/56. Classes 83 (2) and 83 (3). A method of producing metal or other wool from a strip, comprises winding the strip into a coil 33 of overlapping wraps having a conical end surface and rotating the coil whilst advancing a tool 127 axially of the coil to cut wool-forming fibres. The coil 33 surrounds a mandrel 27 which is clamped to a flange 41 on a shaft 75 by plates 45 and dowels 43. A top bracket 13 carrying a winding cone 339 is lowered by a hook 25 on to a base 9, and clamped by levers 15 on posts 11. The coil 33 is positioned at its lower end in a grooved holder 35 supported on a ring 29. A roller 219 runs on the top of the coil and, as the coil is cut, a lever 226 is tilted until a switch 234 is actuated. A motor 274 is then energized to rotate planetary gearing which drives a nut on the shaft 75 to cause the ring 29 to be raised through rods 241. The coil is thus fed upwardly by a small amount. For returning the ring 29 when cutting is complete, one of the planetary gears can be unmeshed and locked, to cause fast travel of the ring downwardly until a lever is moved to switch off the motor 274. There are three similar tool stations, only one of which will be described. The tool bit 127, Fig. 6, has a serrated cutting edge and is gripped in a dovetail holder 129 by a screw 135 acting on a jaw 131. The holder is bolted to a shank 139 carried on a cylinder 186 mounted on a tapered shaft 188 on a slide 159. Weights 201 act upon the cylinder to hold the tool against the coil, whilst opposing weights 203 tend to turn the cylinder in the opposite direction. The weights prevent chatter of the tool, which can be held inoperative by engaging a pin 185 in a recess in the slide 159. The slide 159 is held on guides 161 by a weight 218 and is urged towards the coil 33 by springs 169 under the restraint of a follower 167 engaging a cam 168. The cam 168 causes the cutting edges of the tool to follow the helix of the coil and then to traverse slowly back again. Air is blown through a duct 336 to supply a cooling jet 331 near the tool. Cuttings and dust are sucked away through a pipe 280 depending from the mandrel 27, and connected to a chamber exhausted by a pipe 327. The wool is led from the cutting sections over guides 338 around the canvas-covered rotating cone 339, and then between discharge belts 341, 364. Lubricant is supplied to a cutting section by a pad 375, to which fluid is supplied by a conduit 374. Fibres of the sections illustrated in Figs. 25 and 26 are obtained with an unserrated tool, and may be used for soap pads (thickness 0.002- 0.004 inch), filters (0.004-0.006), camouflage (0.008-0.012) and abrasives (0.0002-0.020). The steel strip used may be 500-foot lengths of 12“ inches Î 0.037 inch cross-section. Alternatively, a brass, copper, bronze, nickel, plastic, soap, abrasive, or impregnated cloth strip may be used.

Title: Torsional vibration damper
IPC: F16F15/129
Filed: 1965-07-16
Abstract: 1,092,428. Vibration-dampers. B. E. O'CONNOR. July 16, 1965 [July 29, 1964], No. 30274/65. Heading F2S. A torsional vibration damper, e.g. for the crank-shaft of an I.C. engine, comprises a plurality of ring-shaped elements consisting of identical elements 10 which alternate with identical elements 12 each of the elements 10, 12 comprising a hub portion 24, and inner and outer rings 20, 16. Rigid spokes 18, 26, and 22, 28 connect respectively the outer rings 16 of the elements to the inner rings 20 and the inner rings 20 to the hubs 24, the spokes 18, 28 being diametrically opposed to the spokes 22, 26 and the outer spokes 18, 26 respectively of the elements 10, 12 being adjacent the inner spokes 28, 22 of the elements 12, 10. The spokes are axially aligned and in the same axial plane. Thin sheet metal shims (30), Fig. 2, not shown, are secured, e.g. by welding, between adjacent hub portions to form the hub of the inertia mass one of the elements having a flange (32) bolted to a crankshaft flange (36). Two, diametrically opposed, groups of four sets of small disc-shaped friction pads 44, 46 have their pads located between the pairs of adjacent surfaces of the elements 10, 12 each pad having one surface bonded to the surface of one of the elements 10, 12. Two sets of friction pads in each group are positioned between the outer, and two between the inner, rings of adjacent elements. Clamping pressure is applied to the elements 10, 12 and to each group of friction pads by means of a bolt 62, which extends through the spaces between the inner and outer rings of the elements 10, 12 and which has its head and a nut 64 located in annular washers 58, 58 carried by a pair of plates 48, 50 secured, by slidable rivet connections 52, 59, to the hub of the inertia mass. In operation, due to the location of the spokes 18, 22, and 26, 28, the outer and inner rings of the elements 10, 12 distort in opposite directions, the vibration energy being absorbed by the friction pads. In a modification, Fig. 7, not shown, the composite inertia mass is substantially the same as that described above and is enclosed by a casing, the spacing of the outer rings of the inertia elements being less than that between the inner rings and the easing being filled with viscous fluid. The housing is formed of two sheet metal stampings, with nested outer walls reinforced at their edges by a pair of metal rings brazed to the housing, and having outwardly-bowed side walls.
Patent GB-677150-A (GB)
Title: Improvements in or relating to the purification of gas mixtures
IPC: B01D53/04
Filed: 1949-11-25
Abstract: In a process for separating adsorbable constituents from gas mixtures by means of two adsorbers which are alternately charged and partially regenerated by washing gas free from adsorbate, the adsorbent is charged to below 50 per cent of its equilibrium charge and below 90 per cent of its break-through charge, and the time of charging and regenerating is substantially 5-30 minutes. Washing gas may pass through the adsorbers in the opposite direction to the gas reated; 3-4 volumes of washing gas per volume of feed gas may be used. Preferably the adsorbent is of 1-2 mm. grain size and is arranged so as to have a cross-sectional area of 0.5-1 square meter per 1,000 cubic meters of gas treated and a layer length of at least 1.5 meters.  The whole process may be carried out at or below room temperature, or the temperature of the washing gas may be increased by at least 3 DEG C for each halving of the ratio of the volumes of washing gas and feed gas.  The adsorbers may be built one inside the other to facilitate heat exchange, and the changeover may be effected automatically when the adsorbent reaches a predetermined temperature. In an example 99.5 per cent of the carbon dioxide present in air is removed using activated charcoal as the adsorbent, and nitrogen free from carbon dioxide as the washing gas.  Specification 633,137 is referred to.

Title: Colour television receivers
IPC: H04N9/68
Filed: 1951-12-28
Abstract: 702,627. Television. RADIO CORPORATION OF AMERICA. Dec. 28, 1951 [Jan. 3, 1951], No. 30314/51. Class 40 (3). [Also in Group XL(c)] In a colour television receiver the gain for the low video frequency portion of the video signal is controlled in dependence upon the scanning synchronizing signals and the high video frequency response is varied inversely with the amplitude of a colour synchronizing signal whose frequency lies in the upper portion of the video range. Changes in high frequency response of the channed may thus be automatically corrected. A video amplifier stage 24 of a receiver utilizing A.G.C. operated from the scanning synchronizing signals comprises a series circuit 26, 28 tuned to the sub-carrier frequency of the colour synchronizing signals and the tuned circuit is damped by a valve 20 connected across part of inductor 28. The amount of damping and thus the high frequency response is con trolled by the grid voltage of valve 20 which is derived from the colour synchronizing signal rectifier 18. The damping valve 20 may alternatively be connected across the resistive anode load of a video stage to vary the low frequency response, Fig. 3 (not shown), the receiver A.G.C. voltage being derived from a later stage so that effectively the high frequency response is varied. The frequency response control alternatively could be applied to a high frequency stage and could use a reactance valve.
