Title: Improvements in printing machines
Inventor: HANDLEY JOHN
IPC: H04L17/26
Filed: 1960-07-06
Abstract: 980,076. Typewriters &C. CREED & CO. Ltd. June 15, 1961 [July 6, 1960], No. 23567/60. Heading B6F. A teleprinter or like printing machine has a printing head 40 comprising a plurality of rotatable type-carriers 1, 2, 3, 4, each of which carries a plurality of individual characters, the printing head 40 itself being both rotatable to position a selected type-carrier in printing position, and axially positioned for the selection of a particular row of characters. Thus, to effect selection, three separate movements are necessary and these are derived from a six-element or binary code which operates a particular combination of relays. These relays have operating contacts arranged as a tree (see Fig. 6, not shown) so that an electromagnet 21 or 36 is operated in each of the three separate mechanisms effecting character selection. The type carriers 1, 2, 3, 4, as described, each carry four rows of four characters rotatably journalled in plates 77, Fig. 2, and geared to a wheel 6 pinned to a spindle 7 driven by a bevel-pinion 8, crownwheel 9, shaft 79 and a pulley wheel 10. Two Bowden cables 11, 12 are attached to the wheel and these are adjustably connected to plungers 15, Fig. 4, having shoulders 104 which are engaged either by a right-hand bail 32, oscillated one unit of movement by a follower 30 and cam 29, or engaged by a left-hand bail 35, oscillated three units of movement by a follower and cam 33. Which bail 32 or 35 is effective is determined by the leftward or rightward movement of the plungers 15 by plates 19, 105 attached to armatures 20 of the electromagnets 21 or 36. Arcuate rotation of the head 40 to position a particular type-carrier 1, 2, 3, or 4 is determined by the rotation of a sleeve 41 coaxial to the spindle 7 and driven by a similar mechanism. A further similar mechanism rotates a gear 58 engaging a rack 57 on the sleeve 41 to position axially the type-head 40. Each of the home positions is central of the four positions so that movements of one unit or three units in either direction achieve any of four different positions. In this embodiment described, 64 characters are provided but by the addition of a further cam, three position control electromagnets and five or six type-carriers each with five or six characters then 125 or 216 characters would be provided for. Letter-spacing arrangements.-The type-head 40 is mounted on a print-head 100 comprising a carrier frame 102 slidably supported on two horizontal rods 69, 70. The head 100 is moved in either direction for letter-spacing by a 45 degrees helically grooved lead-screw 68. A spring box and tape may return the head 100 when the stepping and retaining letter-space pawls are lifted. The spring box may be connected directly to the lead screw. Impression arrangements.-Printing is effected by swinging the print head 100 against the platen 101.

Title: Improvements in kilns
IPC: F27B9/02
Filed: 1919-09-29
Abstract: 140,740. Zwermann, C. H. March 27, 1919, [Convention date]. Tunnel kilns.-The invention is described in connexion with two adjacent tunnels operating in opposite directions, and relates mainly to (1) the heating of the firing zone and temperature control therein by control of the outlet of hot gases from different points thereof (left-hand half of Fig. VIII. and Fig. X.), (2) heating of the preheating zone, partly by hot gas flues (right-hand half of Fig. VIII.) and partly from the cooling zone of the adjacent tunnel (Fig. VI.), and (3) means for cooling parts of the tunnel and preheating the air for combustion (flues 26 and 31, Fig. VI.). The burners 10, Fig. VIII., supplied from an adjacent gas-producer, deliver at the top of the tunnel, and the hot gases, deflected downwardly through the goods, are drawn off at the bottom into flues 15, 16, 17 arranged below the burners. These flues open respectively from the three sections of the firing zone fired by the three burners 10 (see longitudinal section, Fig. X.), and then by controlling the draught therein (by dampers at the chimney end), localized temperature control is effected. The flues 15, 16, 17 on their way to the chimney are carried in a recess 18 in the preheating zone, where they are constructed of short sections mounted in transverse walls 19, Fig. X., and set up a hotair circulation through the goods. The initial preheating, or " water-smoking," zone is heated by air circulation from flues 32 in the division wall receiving heat from the cooling goods in the adjacent tunnel. To provide preheated air for combustion, and prevent overheating of the trucks &c., air admitted near the centre of the tunnel flows along bottom fluea 26 towards the ends, Fig. VI., and thence travels in the opposite direction through flues 31 in the tunnel crown to the burners, Fig. VIII. Oil or like firing may be employed a.s an alternative.

Title: Improvements in or relating to electric motors
IPC: H02K27/12
Filed: 1931-08-27
Abstract: 387,024. Alternating current commutator and induction motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hull, J. I. ; 1338, Dean Street, Schenectady, New York, U.S.A.) Aug. 27, 1931, No. 24140. Convention date, Aug. 28, 1930. [Class 35.] Exciting.-A multipolar motor which has been made to run at creeping speed by inserting a resistance in the armature circuit is stabilized at that speed by altering the distribution of flux so as to produce a generator torque which modifies the speed-torque curve in the required manner ; this is effected by injecting a constant or slowly-periodic voltage into selected windings. Fig. 1 shows the invention applied to a motor of the type described in Specification 25358/11, [Class 35, Dynamo-electric generators &c.]. The rotor carries a three-phase four-pole primary winding 15 .. 26 and drum-wound winding 34 connected to the commutator 35, opposite segments of which are connected by equalizing leads 36. On the commutator 35 bear brushes 37 .. 48 connected to the windings 51 . . 62 of a three-phase four-pole stator winding. Opposite brushes are connected by leads 49. To obtain a creeping speed the brushes 37 .. 48 are shifted to give a minimum speed as described in the above-mentioned Specification and the speed is further reduced by inserting resistances 63, 64, 65, 631, 641, 651 in the stator circuit. To stabilize this speed direct current or slowly-periodic current is injected into the stator circuit from a battery 68 or generator 69 by means of a switch 70. On moving this switch to the right current is injected into the stator windings at the points 73, 74 producing a flux which unbalances the potentials across the leads 36, thus producing a generator torque represented by the line T in the speed torque diagram, Fig. 2. This combines with the motor torque represented by the line 1 giving a resultant torque represented by the line P, and the slope of P being slight the creeping speed is stable. By moving the switch 70 to the left current is passed into windings 66, 67 producing a more concentrated flux and a stronger effect. Fig. 4 shows the application of the invention to an induction motor. The speed is reduced by adjustable resistances 148 in the rotor circuit. The phases of the stator circuit are connected in Y by switch blades 119 and a lead 131 during normal running and also when stabilizing voltage is injected into separate windings 125, 126 by moving a switch 121 to the right. On moving the switch to the left the stabilizing voltage is injected into the ordinary stator windings, which are then connected through resistance 130. Fig. 5 shows the invention applied to a four-pole continuous current motor. In addition to the ordinary windings 156 the poles carry windings 157, two of which oppose the windings 156 and two of which assist them, thus producing an unbalance in the drumwound rotor 160 and creating a stabilizing generator-torque.

Title: A forming or impacting machine
IPC: B21J7/24
Filed: 1961-07-05
Abstract: 923,716. Forging hammers. GENERAL DYNAMICS CORPORATION. July 5, 1961 [Oct. 31, 1960], No. 24256/61. Class 83 (4). A power hammer has its ram 126 connected with means 122 for compressing a gas in chamber 130 during the retraction stroke, the compressed gas being used to perform the subsequent working stroke. The ram is of rectangular plan shape, Fig. 2 (not shown), and is guided by segmental bushes 140 co-operating with four guide rods 36 extending between a bolster 50 and a cross-head 38. The latter carries an inner cylinder 120 which co-operates with outer cylinder 122 secured to the ram, to define the pressure chamber 130 which has a gas-filling pipe 138. Bolster 50 has depending therefrom a closed cylinder 58 containing a stationary piston 72 which divides the cylinder into chambers 74, 80 with filling ports 78, 84 respectively, for pressure gas. Ram 126 carries a top tool 142 co-operating with a die 112 on the bolster. The ram is raised mechanically by hooks 194 on endless chains 188 driven through toothed gearing and a flywheel by an electric motor 180, Fig. 2 (not shown). The speed of the motor or the gear ratio is variable for varying the impact rate of the hammer and the vertical position of the chain 188 is adjustable for varying the stroke. Guide rods 36 pass through bearing blocks 32 on frame members 10 of welded construction secured to a baseplate 12. In operation, the hooks 194 engage spring-loaded shock-absorbing plungers 210 of the ram 126 and raise it to its upper limit, thereby compressing the gas in chamber 130. Continued rotation of the chains 188 causes the hooks to release the ram which descends rapidly and presses the workpiece in die 112. Simultaneously the reaction in chamber 130 causes the bolster 50 to be raised slightly but upon impact and also due to the pressure in chamber 80, the bolster moves downwardly whereby a stationary ejector rod 114 removes the workpiece from the die. In another embodiment, Fig. 7 (not shown), the chains 188 are mounted on brackets carried by the bolster and the cylinder 58 is open at its lower end. In a further embodiment, Fig. 8, the ram 280 is raised by hydraulic or pneumatic pressure admitted to telescopic chambers 312 through large passages 316 which are subsequently opened by automatically controlled valves to cause a quick downstroke of the ram and simultaneous upstroke of the bolster 232.
