Abstract: 611,253. Motor vehicles. SIMMS MOTOR UNITS, Ltd., and LIARDET, G. E. April 24, 1946, No. 12416. [Class 79 (iii)] A steerable road vehicle is provided with a main internal-combustion engine or turbine and an auxiliary internal-combustion engine or turbine which drives means operable to produce fluid pressure or electrical energy or both, sufficient at least to ensure the effective operation of the starting and/or ignition equipment of the main engine independently of an accumulator. The auxiliary engine may be a single cylinder air-cooled engine of, say, 2¢ h.p., mounted in a sound-insulated box and connected to the main engine exhaust system, it may be started from a compressed air bottle, or by hand. The auxiliary engine drives a dynamo and supplies current for the major portion of the lighting and electric auxiliaries without the use of an accumulator. The dynamo may supply alternating current for fluorescent lighting, e.g. in a passenger-carrying vehicle, in which case a small accumulator may be provided for the vehicle driving lights. The auxiliary engine may also drive a compressor and the compressed air used for starting the main engine, for power steering, jacking, braking, door operation, windscreen wipers or inflating tyres. The auxiliary engine may also drive fans for cooling the main engine and for ventilating, heating or cooling the vehicle interior. In the case of a fan for cooling the main engine radiator, the fan may be driven directly from the auxiliary engine, or it may be driven by an electric motor from current supplied by the dynamo and may then be thermostatically controlled.

A film having a base of cellulose ethers or esters with a light-sensitive silver gelatinohalide layer on one side is immersed in a solution of a diazotizable amine such as o-anisidine, then immersed in an acidified sodium nitrite solution so as to form a diazonium salt in the base, exposed through a positive, treated in an alkaline bath of coupler such as 3-methyl-l-phenyl- 5-pyrazolone to form an elementary picture in the base itself, and at least one other picture is formed in the sensitive layer. In an example the silver gelatino-halide layer is first exposed, developed, fixed and washed; the azo dye picture is then formed in the base by the procedure indicated above, the silver in the gelatino layer is toned to prussian blue, and for the third picture the film is treated with ammonium bichromate solution, exposed under a positive and dyed as with cochineal, carmoisine or amaranth. If desired, the third picture may be obtained by superimposing a silver gelatino-halide layer on the blue picture, and exposing, developing and colouring this layer; or the third picture may be obtained by applying a gelatine layer either containing or subsequently impregnated with the reagents necessary for the hydrotype pinatype, diazo compound destruction or diazosulphonate processes ; or such processes may be effected in the layer already containing the blue picture. When the first formed picture is the one in the base itself, processing procedure may be such as to dry the film on the base side only, and allow the sensitive layer to remain moist. Specification 20433/14, [Class 98 (ii)], is referred to.

Filed: 1938-04-28
Abstract: 510,630. Coil-winding apparatus. TRIGGS, W. W. (Micafil Akt.-Ges.). April 28, 1938, No. 12687. [Class 35] A machine for winding slotted armatures has the mechanism controlled by a counter, the tripping action of which effects the stopping of the rotary face plate carrying the armature the carrier being disconnected from its drive and braked after which the brake is removed, the carrier is rotated by an auxiliary drive and a slot advancing movement is performed. In the form shown, the armature 1 is carried by a faceplate 10 driven by a pulley 17 from a winding motor (not shown) the counter 24 indicating the revolutions of the faceplate. Just before the required number of turns has been wound, the counter causes the winding motor to be switched off by a mechanism including link 39, lever 42 and cam 22 and simultaneously causes the application of a brake to the faceplate, followed by the removal of the brake. When the brake is released, a friction wheel driven by a second motor is brought into engagement with a groove in the periphery of the faceplate and rotates it until the slot 12 therein containing the slide 13 for producing angular movement of the armature is vertical. The lever 42 then permits the clutch 27 to drive a shaft 28 from the second motor (not shown) through gearing 26 and a cam 64 on shaft 28 actuates the slide 13 through link 65 and enables the armature to be moved one slot pitch about its axis by pawl 14. A predetermined movement of the clutch 27 resets the counter and lever 42 is enabled to cause the closing of the winding motor switch. The shaft 28 drives a gear 31 arranged to disconnect the motor driving this shaft after one revolution of the gear 31 which corresponds to one revolution of the armature about its axis, the gear 31 being readily interchangeable and having a number of teeth proportional to the number of slots in the armature.

Title: Improvements in or relating to methods and machines for the manufacture of bags having crossed ends
IPC: B31B170/20
Filed: 1931-04-30
Abstract: 377,972. Making paper bags. ANDREAS, A., 3, Engelstrasse, Munster, Westphalia, Germany. April 30, 1931, No. 12798. Convention date, April 30, 1930. Addition to 361,318. [Class 94 (ii).] A paper tube, which may comprise more than one layer of paper and display printed matter, is cut into sections whereof the ends of one wall of the section are folded over automatically preparatory to cross bottoms being formed as described in the parent Specification, the finished bags being then counted and bundled. Four layers of paper 2, gummed at 9 and the uppermost printed at 8, are brought together and secured by rolls 3, staples having been provided from a supply 10 to strengthen the web thus formed. While a former 4 converts the web into a tube, a rotary cutter 12 makes semicircular incisions in the upper wall of the tube and thereafter a rotary knife cuts it into bag sections which are deposited on a conveyer 7 moving transversely of the direction of movement of the web. A narrow belt 13, above the conveyer 7 guides each section between the halves 19, 19<1> of a prism which rotates about its longitudinal axis on a shaft 14 supported in bearings 15, 16. Associated with each half prism is a stationary drum 29 formed with cam-tracks 28 adapted to operate sets of levers 22, 23, 25 of which each side of the prism carries one set. A further camtrack 33 actuates a slide 30 movable parallel to the shaft 14. The tube section is seized at each end by a clamp 21 on one of the levers 22 and pressed into a stepped position 19a of the prism, the ends being thus bent upwards. Fingers 26 on the lever 25 pass through the semicircular cuts in the upper wall and press down the lower wall. The ends of the bag are thus opened and. the slides 30 pass into them to fold the upper wall over about the clamps 21. Plates 24 on the lever 22 then press the triangular end flaps formed by the folding operation. The prism moves in the opposite sense to the conveyer 7 and stops 40 remove the tube section on to another conveyer for transference to the bottom-forming machine described in the parent Specification. The finished bags drop on to an intermittently moving conveyer disposed transversely of the bottom-folding machine and are thereby counted and bundled. The prism-half 91<1> is slidably keyed to the shaft 14 to make it adjustable for different bag lengths, its drum 29 being likewise displaceable along the machine bed. The device may supply two bottom-folding mechanisms, feeding to them alternately, the bags, when finished, being collected on a single conveyer. Moreover, a single tube forming mechanism may supply two endfolding machines.
