Title: Improvements in or relating to oxygen jet cutting machines
IPC: B23K7/00
Filed: 1935-03-19
Abstract: 451,616. Dividing by fusion; toothed gearing. HANCOCK, L. J., 85, Brighton Road, Sutton, Surrey. March 19, 1935, Nos. 8601/35 and 8141/36. [Class 83 (iv)] [See also Group XXIV] In a flame cutting-machine the worm wheel in the final drive of the tracer wheel or roller is prevented from overrunning the driving worm by means of a second worm normally driven in syn - chronism therewith and engaging the leading sides of the worm wheel teeth when the thrust receiving sides are in contact with the driving worm, wear being taken up by advancing the driving worm relatively to the second worm. The shaft 1 on the tracer head, which is driven by an electric or clockwork motor, carries a pinion 4, which meshes directly with a pinion 5 and through an idler 6 with a pinion 7. The pinions 5, 7 are carried by shafts 12, 10 mounted in a body 9 screwed into the handle 3 and having worms 14, 13 at their other ends engaging the opposite side sof a worm wheel 15 on a shaft carrying the tracer wheel 16. In order to adjust for back lash the body may be unscrewed from the handle and the pinion 4 withdrawn, whereupon the worm 14 may be independently rotated either through a milled knob on the end of the shaft of the idler pinion 6, or by turning pinion 6 or 7 direct. In a modification the second worm may engage with a second worm wheel on the other side of the tracer, the worm being mounted on either side of the worm wheel according as it is of the same or opposite hand to the driving worm, the idler being dispensed with. According to the first Provisional Specification, the adjustment may be effected by fixing one of the pinions to its worm shaft by a nut, which is released to allow one worm to be rotated relatively to the other to take up back lash.

Title: Combined intermittent and continuous feed gearing
IPC: G03B27/30
Filed: 1939-03-18
Abstract: 526,517. Feeding webs. WILLIAMSON. C. M. March 18, 1939. No. 8707. [Class 100 (i)] [Also in Group XX] In apparatus for feeding a strip intermittently at one part of its travel and continuously at another part, particularly for use in feeding a photographically sensitive strip past a printing position and then through developing &c. baths. the intermittent feed mechanism comprises two spur or ratchet wheels 11, 12, Fig. 2, loose upon a shaft 13 and driven continuously by gearing from a shaft 3 driven by a motor and worm gear 5. Between the wheels 11, 12 and fast to the shaft 13 is an arm 14 to which is pivoted a double ended pawl 15, Figs. 2 and 4, the ends of which co-operate respectively with the wheels 11, 12 and alternately so that the arm 14 and thus the shaft 13 receive an oscillating movement. The reversal of the pawl may be effected by the direct engagement of the pawl with a pair of stops adjustably spaced apart, but is preferably effected by means of a yoke 16, Fig. 4, pivoted on the pivot of the pawl and connected to the pawl by a spring rod 18. Fixed and adjustable stops 22, 23 are engaged by the yoke which is thereby turned until the spring rod 18 completes the reversal of the yoke and at the same time reverses the pawl. Stops 20, 21 limit the movements of the yoke. The shaft 3 drives the intermittent feed rollers through a friction clutch 34, free wheel device 32a, and sprocket wheel 32. The clutch 34 allows the shaft 3 to be given a movement rather greater than that required for the feed, the return movement of the wheel 32 being limited by the engagement of a pin 37  thereon with a pin 38 on a sprocket wheel 31 which drives the continuous feed rollers and is driven continuously by gears 30, 29 from the shaft 3. The shaft 13 also has secured to it a cam which during the rest movement of the strip actuates a plunger to hold the strip stationary in the printing position. A pin on the side of the cam also actuates a trigger to operate a lighting switch for the exposure of the strip.

Title: Electrical transmission, particularly for traction machines
IPC: H02P9/06
Filed: 1934-03-21
Abstract: 435,136. Systems for transmitting mechanical power. SOUSEDIK, J., Vsetin, Moravia, Czecho Slovakia. March 21, 1934, No. 8815. Convention date, April 12, 1933. [Class 38 (iv)] In electrical transmission means comprising two dynamo-electric machines, one element of each machine is fixed to the load element, the other element of one machine is fixed to the crank shaft of the prime mover, the other element of the second machine is held at rest, and the controller for the dynamo - electric machine brings into action a clutch to establish a wholly mechanical drive when the speeds of load and crank shaft are approximately equal. An internal-combustion engine 1 drives a shaft 2 which is connected to the rotor 4 of the dynamo-electric machine G. The stator 3 of the machine G is coupled to a second shaft 5 upon which is mounted the rotor 8 of a second machine M and which is connected to the load. The stator 7 of the machine M is fixed. The excitation of the machines is controlled by a lever 13 moving over a rheostat R to vary the current supplied from a D.C. source 20 to the field circuits and the slip rings of the machine. As the lever is moved to the right, exciting current is led through the circuit 11 to the winding of the stator 3 of the machine G, and its excitation is progressively increased whilst the excitation of machine M is progressively decreased. At the extreme right position the velocities of the shafts 2 and 5 almost correspond and as the lever is moved to the contact 16, the current supply to G, M is switched off and the current to the electromagnet of the clutch 9 also stopped so that a straight-through mechanical drive is obtained. Movement of the lever R in the reverse direction progressively reduces the speed of the shaft 5. A rheostat switch P may be used for braking purposes. Within the range of the angle alpha, movement of the lever 22 controls the throttle arm 21 of the prime mover 1 ; and within the range of angle Y, i.e. when the throttle is closed, the lever arm 22 switches resistance into the rotor of the machine M.

Filed: 1939-03-21
Abstract: 526,574. Signalling over power circuits. GENERAL ELECTRIC CO., Ltd., COLLYER, J. E.; and SMART, N. C. March 21, 1939, No. 8906. [Class 40 (iv)] In a system for controlling power consuming apparatus, a signalling current applied to the high tension network operates a relay at one or more distributing stations after passing through a step-down power transformer, thereby connecting up an amplifier to apply signalling current of the same frequency to the low tension network in a non-retroactive manner. As shown, three-phase signalling current from a generator 25 is applied through filters to the high tension supply wires 16-18, and passes through the step-down transformer 35 and filter 37 to operate a relay 40, which may be of the vibrating type described in Specification 491,980, [Group XXXVII]. An amplifier 38 is thus made effective to reapply the signalling current through a transformer 36 to the low tension network between the centre point of the transformer 35 and earth. Signalling currents of different frequencies are employed for switching on and off. The Provisional Specification mentions a modification in which the relay starts generator of signalling current of different frequency.

Filed: 1945-04-11
Abstract: Iron powder, suitable for agglomeration in the cold, is made by decomposing iron formate by heat in a neutral or reducing atmosphere and, simultaneously or subsequently, submitting the products of the decomposition to a very far-reaching reduction by means of a reducing gas at a temperature between 500 DEG C. and 750 DEG C.  The Specification states that a compression of 5-10 tons per sq. cm. produces goods with a density of about 7 gms. per c.c., with a Brinell figure of 130 and only about 10 per cent voids.  The reducing atmosphere for the decomposition may be nitrogen or a mixture of carbon monoxide, carbon dioxide and hydrogen resulting from the decomposition and used under a partial vacuum, whilst the reducing gas for the reduction may be hydrogen, carbon monoxide, or a mixture of hydrogen and nitrogen, obtained by decomposing ammonia, the reduction of the decomposition products being down to about 1 per cent of oxygen. The decomposition may be effected at 325 DEG C. when it precedes the reduction, and the Specification contains examples of the times and rates of flow of reducing gas necessary for the reduction. The powder may be used for making cores of induction coils, or it may be used alone or mixed with other metallic powders, with or without a binding and insulating agent, for the manufacture of articles such as gears or bearings.
