Abstract: 698,841. Drawing wire. VAUGHN MACHINERY CO. Sept. 3, 1951 [Nov. 21, 1950], No. 20761/51. Class 83 (iv). [Also in Group IX] In a wire drawing mechanism a rotatable wire drawing block comprises a riding stripper removably mounted thereon for rotation therewith and push-up means adjacent said block for engaging the lowermost turn of wire to force said turn upwardly as the block rotates. The block and stripper comprises a housing 1 seated in an opening 2 in a bench 3 and a gear-box 4. A spindle 5 is journalled in bearings 9, 6 and is driven from an electric motor through worm gear 11, 12. An apron 15 is carried by bearings 16, 17 on the gear-box extension 10, said bearings having an axis slightly inclined to the axis of the spindle 5 to cause said apron, when rotated, to rock relatively to a block 19 having a hub portion 20 keyed to the spindle 6. The block has four radial slots 21 for receiving the feet 41 of a riding stripper and corresponding slots 25 are provided in apron 15. The block and apron are interconnected by means of a wobble pin 31 on the apron, the ovoid end portion 32 of which is received within a sleeve 33 carried by a boss 29 on the block. A coilspring 34, Fig. 4, may be used instead of wobble pin 31. The spring is mounted in a sleeve 35 on the block and the lower end of the spring is received in a cup 36 in the apron 15. The spindle 5 has an upper extension 37 for receiving the tubular member 38 of the stripper. The four stripper feet 41 are pivotally mounted at 43 on adjustable studs carried by a collar 44 fixed to the lower end of the member 38. An upper collar 45 mounted to reciprocate along member 38 is connected to the stripper feet by links such as 46, 47. A collar 48 welded to the member 38 limits the downward movement of collar 45. When lifting the stripper and the wire coil from the block the collar 45 is locked in position by a yoke 50. As the block rotates the wire W is wound thereon while engaging the hardened insert 18 in apron 15 and as the block rotates the apron is canted from about 1-5 degrees so that the lowermost turn pushes up the preceding turns. Flat wire and the smaller sizes of tubing may be coiled as well as round wire.

Abstract: 388,299. Mowing-machines. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd., 259, City Road, London. -(International Harvester Co. ; 606, South Michigan Avenue, Chicago, U.S.A.) July 25, 1932, No. 20903. [Class 6 (iii).] A tractor-drawn mower comprising a wheelsupported frame pivotally connected at its front end to the tractor is provided with means connected between the pivoted frame and the tractor to prevent lagging of the cutting mechanism during work. The mower frame 16 is triangular in shape, the sides being connected at the rear by brackets 17 each provided with a collar 18 to take the vertical.spigot of a trailing wheel 46 bracket such spigot being yieldingly held against turning in normal circumstances by a spring-pressed looking device 49. The apex at the front of the frame carries an upright housing 19 fitted near its base with a pair of draw-bars 20 detachably connected by pins 21 at spaced points to draw-bars 15 on the tractor. The frame is stiffened by a cross brace 22 that carries a depending bracket 23 supporting a housing 24 pivotally connected with the housing 19 so as to be capable of swinging about the axis of that housing. Lugs 26 on the housing 24 pivotally carry a coupling rod 27 secured to a shoe 33 on a yoke 30 of the cutting mechanism. A second coupling bar 29 extends to this yoke from a pivot 28 on the rear bar of the frame in axial alignment with the housing 24. The shoe 33 carries the usual cutter mechanism 35 that may be tilted in the ordinary manner. The cutting mechanism is driven from a power take-off shaft 14 on the tractor through a universally jointed shaft 37, a shaft 40 driving a vertical shaft in the housing 19, such shaft in turn driving an horizontal shaft in the housing 24 which carries at its rear end a crank-pin 44 for the usual connecting- rod 45. To prevent rearward sagging of the cutter bar during the normal operation of the machine a bracket 50 forming a bell-crank lever is pivoted on the frame 16 ; one arm of this lever is connected by a pull-rod 53 and a flexible connection such as a chain 54 to a bracket 55 on one of the draw-bars 20 of the tractor, the point of attachment being forward of the turning pivot for the mover frame in the vertical housing 19. The other arm of the bell-crank lever is connected through one or more tension springs 56 to a rod 57 attached to a bracket on the stubbleward side of the mower frame. The tension of the springs may be adjusted by a nut on the rod 57. The springs are so arranged that they exert a force on the mower frame urging it in a grainward direction against its tendency to sag under a heavy cut but permitting the frame to yield rearwardly and the supporting wheels to caster should an obstruction be struck. Specifications 332,457 and 335,881, [both in Class 6 (iii), Harvesting- appliances], are referred to.

Title: Improvements in impulse transmitters for automatic telephone systems
IPC: H04M1/274
Filed: 1936-07-29
Abstract: 476,127. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and COLLYER, J. E. July 29, 1936, No. 20996. [Class 40 (iv)] In a substation or operator's circuit provided with keys for transmitting a limited number of multi - digit numbers corresponding to frequently-wanted subscribers, a step-by-step switch PS is set to a position corresponding to a depressed key to effect markings in a bank of a second step-by-step switch DS producing impulses under the control of a relay having a vibrating reed-type armature, the switch DS being stopped at each marked position to provide the inter-digital pauses. For example, to transmit the number 375, the third, tenth, and fifteenth contacts are marked. When key 1 is operated, relay S energizes connecting selfinterrupting magnet PS to wiper PS1, and the switch PS hunts until the contact from which earth has been removed by the operation of the key is reached. Relay K then operates and on the release of key 1 the vibrating armature MW of relay M transmits impulses to magnet DS and over the subscriber's line. When the first marked contact is'reached, relay P operates over wiper PS2, cross-connecting frame TP, and wiper DS2 to hold relay M and energize relay PA. Relay P releases relay C which in turn releases P and an inter-digital pause is provided by the time of relapse of relays C and P. Impulsing then continues, the second digit being terminated by operation of P over wiper PS3. After the third digit, relay T operates over wiper PS4, short-circuiting the impulse contacts and completing a homing circuit over wiper DS1 for switch DS. A lamp EL is lit during impulse transmission to warn the subscriber or operator not to press any further key.
Patent GB-358580-A (GB)
Title: Improvements in the production of sulphur
IPC: C01B17/04
Filed: 1930-07-11
Abstract: In the production of sulphur from gases containing sulphur dioxide by reduction with carbon, the gases, the oxygen content of which is insufficient to maintain the reaction temperature, are passed, e.g. downwardly, through a bed of coal at a temperature high enough to carbonize the coal, at least 400-500 DEG  C.  The gases and vapours produced then pass through a bed of highly heated coke, substantially free from volatile matter and produced by the carbonization of the coal, together with sufficient air to maintain a temperature of 1000-1200 DEG  C., where the reduction of the sulphur dioxide is completed and the tarry matters cracked. The air is preferably introduced at a point in the coke bed below that of the entry of the gases to be treated and the resultant gases are withdrawn at a still lower point, the outgoing gases being used to preheat the air and the initial gas; the outgoing gases may also be passed through an annular chamber surrounding the top of the fuel bed.  The resultant gases may contain some carbon oxysulphide and sulphuretted hydrogen which last may be reduced by the addition of sulphur dioxide in the presence of a catalyst, such as bauxite, if desired.  Any excess of reducing gas, e.g. carbon monoxide, in the outgoing gases may be utilized by adding sulphur dioxide to effect a secondary reaction in known manner.  The sulphur may be recovered in the manner described in Specifications 354,207 and 355,832.  Specification 357,178 also is referred to.

[Also in Group XL (b)] A stop motion for use in conjunction with textile machines comprises a source of light L, a light beam adapted to be influenced by breakage, lapping or displacement of a sliver or yarn passing through the machine, and a photo-electric cell P upon which the light beam is directed, the cell P being connected to the striker of a gas filled cold cathode discharge tube G which is' normally non-conductive. Due to the interruption of the light ray, the tube G discharges with the result that the current in a relay A falls below its release point so that it releases and opens its contact A1, thus disconnecting current from a winding T1 so that an alarm circuit is interrupted and the main circuit breaker is operated to stop the machine. In an alternative embodiment two light beams are directed on to the photocell and such beams are normally obstructed by vanes, one of which moves out of the beam, on the occurrence of a fault, thus allowing the photo cell to become conductive.

Title: Improvements in or relating to vacuum gauges
IPC: G01L9/00
Filed: 1929-07-11
Abstract: 315,325. General Electric Co., Ltd., (Assignees of CeskomoraoskÓ Kolben-Danek Akciova Spolecnost, Farbinger, F., and Cacheux, R.). July 11, 1928, [Convention date]. Liquid-level pressure gauges.-Comprises a mercury type vacuum gauge used for automatically starting and stopping a vacuum pump wherein the height of the mercury level is controlled by rotating the gauge around the axis of the inlet pipe therefor. The gauge comprises a glass tube s of annular form which is connected to the vacuum valve o by a part of the gauge which is at rightangles to the annular part. The groove d in the valve body establishes communication between the gauge and the vacuum tank. For adjusting the pressures at which the mercury in the gauge engages the contacts a, b the valve need be turned just a small amount. It is closed by rotating it through 90‹. The three contacts a, b, c are fused into the glass and serve for starting, stopping and supplying current to the motor driving the pump. When the vacuum is low, the mercury fills the tube s and the contacts a and b are connected with the contact c. The relay A is thus energized and the contacts k<1>, k<2> close, the contact k<1> completing the circuit for the contactor B and the pump starts. As the vacuum increases the mercury falls, and when the contact b is passed the pump stops. The meroury level has to reach the contact a before the relay A is energized to restart the pump. In the case of failure of the gauge, the latter is rotated until the stationary contacts come to position 4 when the motor is started by operating the hand switch v. By moving the gauge to the position 5, the contacts are disconnected and the gauge may be dismantled. The contacts m<1>, n' and p<1> are carried by the rotating part of the gauge. Normally the two upper pairs of stationary contacts engage the movable contacts m<1>, n<1> between positions 1 and 3.
