Abstract: 300,944. Taylor, C. W. July 21, 1927. Driving-gear and feeding-devices for endlesschain conveyers.-In apparatus for manufacturing moulded heat-treated articles a series of moulds filled. in an automatic or semi-automatic machine with the material to be heat treated are transferred automatically to a conveyer which carries them through the heat treatment apparatus, the filled moulds entering such apparatus and leaving it at different points. The apparatus is stated specially to be applicable to the manufacture of rubber articles. The moulds 10 are filled in an automatic machine, e.g. that described in Specification 224,948, [Class 87 (ii), Moulding plastic, &c. substances], in which they rest in sockets on a disc 3 and are transferred by a pusher 28 along a platform 5 to a cradle 9 of an endless conveyer 7 which carries them through the oven 6. If it is attempted to overload a cradle, the door 12a is pushed open and attracts attention. The pusher 28, Fig. 3, is mounted on one end of a rod 26, the other end of which is engaged by the forked end of an arm 21 pivoted at 25 to the frame cf the machine. A pin 20 on the arm 21 enters an arcuate slot 19 in a disc 18 which is connected by bevel gears 17, 16 to a gear 15 meshing with a toothed sector 14<b>. A spring 22 is attached to the arm and to the disc. The toothed sector 14b is actuated by a connecting rod 12 from the driving pulley 1 of the automatic machine. The rod 12 also is connected to a lug 31 on a member 30 mounted on the shaft carrying the sector 14b.

Patent GB-194703-A (GB)
Abstract: 194,703. National Cash Register Co., (Assignees of Pein, E. J. von). April 13, 1921, [Convention date]. Cash registers with item - printing and voucher-issuing mechanism.-In machines of the kind described in Specifications 10213/93 and 142,436 wherein the item is printed from type wheels 112 upon a record-strip 220 and upon a voucher strip 221, and in which the voucher issuing and impression mechanism may be disabled by setting a disc 300 in the " off " position, incomplete, setting of the disc locks the operating-mechanism of the machine and the disc cannot be turned during an operation. The voucher strip 221 passes between plates 252, 253 and under fixed type 281, 280, date and number type and the amount-printing type 112 to a feed roller 255 engaged by a pressure roller 256. When the disc is rotated clockwise, an eccentric slot engaging a pin 304 raises a vertically slidable bar 305 and consequently the pressure roller 256 so that the strip is no longer in contact with the feed roller but is held between the bar and the roller 256. The rotation of the disc 300 which is fixed to its shaft 301 also effects through a pin and slot 308, (Fig. 4) a bar 309 and crank arm 311, a counterclockwise rotation of a shaft 193, Fig. 2, carrying an eccentric collar 291 on which the platen-operating arm 289 is pivoted. Consequently, this arm is turned about its cam-actuated roller 292 so as to lower the platen support 284 out of effective position. The left-hand end of bar 309, Fig. 4, is connected to an arm 313 pivoted at 184 and depending into proximity to a pin 181 on the end of the lever 175 which is rocked at each operation of the machine as described in Specification 178,417. Unless the disc 300 occupies one or other of its extreme positions, therefore, the lower end of the arm 313 blocks the movement of this lever 175 and so prevents operation of the machine. Similarly during such operation the lever obstructs the arm and thus renders impossible anv movement of the disc 300. A lever 268 pivoted' at 269 is rocked during the printing-operation by means of cams driven from the electric motor which is controlled by a clutch and switch of the kind described in Specification 17534/08. The lever is toothed to drive the voucher-feed mechanism 263 and is provided with two cam slots 250, 320 for operating the type aligning device 245 and' the consecutive number printer 283 respectively. A link 336 serves also to rock arms on a shaft 327 and thus actuate the record-strip feed 225 and the ink-ribbon feed 331.

Title: Taper roll machine and method
IPC: B21H7/00
Filed: 1963-05-21
Abstract: 974,990. Rolling leaf-springs. ROCKWELLSTANDARD CORPORATION. May 21, 1963 [June 26, 1962], No. 20131/63. Heading B3M. Apparatus for roll tapering a blank to form a leaf-spring of predetermined longitudinal contour comprises means for supporting a metal blank to be rolled and for horizontally moving the blank, and a forming roll which is positively driven about a horizontal fixed axis at rightangles to the direction of movement of the blank and which is vertically adjustable to roll the blank to a desired contour. A carriage 36, Figs. 1 and 2, is slidably mounted by bearing surfaces 26 and 39 and adjustable blocks 30 on the bed 18 of the machine and is reciprocated by an hydraulic piston 48. Die blocks 60 and 62 and cam blocks 70 confine a block 68 within the carriage 36, the blocks being press fitted or adjustably clamped in the carriage. A roll 76 and two cam followers 73, all of the same diameter, are fixedly mounted on a driven shaft 81, the bearings 78 of the shaft being attached to an hydraulic piston 86 to allow vertical adjustment of the roll. The bearings 78 move in vertical guides on the machine frame, the guides on one side of the machine being adjustable. From the position shown in Fig. 1 the carriage is moved to the left and, as the cam followers are pressed against the cam blocks 70, the blank is tapered to the same profile as the blocks. The carriage is returned to its central position and the other half of the blank is similarly rolled. Alternatively, rolling can start at one end of the blank and be in one step. Spring- urged pressure rollers 91 which act on the blank, prevent one end of the blank from lifting as the other end is rolled. The die blocks 60 and 62 which confine the block can, if desired, be integral. In an alternative embodiment, Fig. 4, the cam followers and roll 76 are formed as a single roll and the cam blocks 70 form confining surfaces for the blank. The carriage is driven by gearwheels 118 and is supported by a roller 126, or, if desired, is reciprocated as before on bearing surfaces. The speeds of the roll 76 and carriage are synchronized to avoid slipping of the roll on the blank. U.S.A. Specification 2,775,152 is referred to.

Title: Improvements in or relating to voltage regulators
IPC: G05F1/52
Filed: 1947-07-25
Abstract: 642,673. Automatic voltage control systems. WESTERN ELECTRIC CO., Inc. July 25, 1947, No. 20132. Convention date, July 14, 1944. [Class 38 (iv)] In voltage regulators of the type comprising, in series with the load, a valve controlled by an amplifying valve, the amplifier control voltage is the resultant of a voltage proportional to the load voltage opposed by a voltage proportional to the load current and opposed by a stabilized reference voltage; further, the anode/cathode voltage of the amplifier valve'or the stabilized reference voltage may be made greater than the load voltage. The output voltage of rectifier 10 is stabilized by a series valve' 12 controlled by a pentode 11 connected, in series with a load 19, across the output. The screen grid of valve 11 is supplied at a reduced voltage by the output of a second stabilized rectifier 26. The control grid is subject to the voltage across resistance 25 (proportional to load voltage, opposed by a small voltage across resistance 17 (proportional to load current) and also opposed by a portion, tapped off potentiometer 23, of a reference voltage derived from rectifier 76 and stabilized by a discharge tube 21. A gas-filled tube 90 connected between anode and cathode of valve 11 prevents the load voltage rising to an excessive value. The output voltage of rectifier 26 is stabilized by a series valve 28 controlled by a valve 27 having its anode load connected to one side of the output and the cathode connected via potentiometer 39 and resistance 37 to the negative side of the auxiliary supply derived from rectifier 76. thereby increasing the anode/cathode voltage. The screen grid is supplied from the relatively positive side of the auxiliary supply. The control grid is subject to the voltage across resistance 36 having variations corresponding to load voltage changes, opposed by the voltage across resistance 33 (proportional to load current) and also opposed by a reference voltage derived from the auxiliary supply, applied across potentiometer 39 and resistance 40, and stabilized by a discharge tube 38. The output voltage of rectifier 51 is similarly controlled by a series valve 53 and amplifying valve 52 except that the cathode voltage of valve 52 is fixed whilst the control grid voltage is adjustable.

Title: Process for producing a high grade gas rich in hydrogen
IPC: C01B3/38
Filed: 1929-07-01
Abstract: 314,870. Vereinigte Stahlwerke Akt.- Ges., (Assignees of Schulz, E. H., and Eisenstecken, F.). July 3, 1928, [Convention date]. Gaseous mixtures rich in hydrogen are obtained by passing distillation gases and hydrocarbons in admixture with superheated steam over catalysts at temperatures not less than 1000‹ C. Catalysts specified are iron, cobalt, nickel, chromium, aluminium, manganese, copper, vanadium, tungsten, and the alloys or mixed crystals of these elements. The gaseous product is free from hydrocarbons such as methane, and may be used for reducing iron ores or for the production of pure hydrogen, or hydrogen containing mixtures for ammonia or methanol synthesis. The reaction may be carried out in a channel of refractory material such as carborundum, which in this case also acts as a catalyst, heat being supplied externally by combustion gases; or the reaction gases may be passed through similarly heated metallic tubes containing catalysts and embedded in a channel lined with refractory material. These tubes may be mounted on refractory supports so formed as to guide the combustion gases which heat them. The heating may be effected by electrical induction currents produced either in the catalyst itself, or in suitably shaped metallic bodies in the reaction space. The initial gases may be preheated by the waste gases generated in the process, and should also be freed, before treatment from sulphur compounds in known manner. In an example, coke oven gas is passed together with superheated steam over a catalyst consisting of chromium and aluminium. The resulting gas consists almost entirely of hydrogen, nitrogen and carbon monoxide. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of silicon, or carbon as catalysts. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 401/11, [Class 90, Non-metallic elements], 163,703, and 274,610.
