Abstract: 751,232. Toys. ERNST. M. Jan. 25. 1954 [Feb. 12. 1953; May 23, 19531, No. 2116/54 Class 132(3) A toy, e.g. a vehicle, has two or more coupling wheels which, when driven. cause it to perform different actions, and are drivable selectively by transmission means comprising a core wire 26 within a hollow shaft 23 of which one part is rotatable and carries two or more corresponding coupling wheels which latter may be engaged selectively with the first coupling wheels by relative longitudinal movements of the wire and shaft. A toy tank comprises a rigid frame 1 carrying three crown wheels 2, 3, 4 mounted on shafts 5. 9, 16 respectively. Fig. 4. Shaft 5 drives through pinion 6 and toothed wheel 7 of a driving shaft 8 and shaft 9 drives, through a series of pinions and wheels, a driving shaft 15 so that when the crown wheels 2, 3 are rotated in opposite directions at the same speed they drive shafts 8, 15 in the same direction at the same speed. Shaft 16 carries a toothed wheel 17 and hence friction wheel 19 so that, when shaft 16 is driven, sparks are produced. Bearings 20, 21 are mounted on frame 1 to support a longitudinally slidable thin tube 22. This tube 22 is fixed to flexible hollow shaft 23 and carries pinions 24, 25. Wire 26 passes through tube 22 and is fixed to a plate 27 secured to a bracket 28 on frame 1. When the pinions 24, 25 are in the position shown in Fig. 2, only crown wheel 4 is driven to produce sparks whereas in the position shown in dotted lines only crown wheel 3 is driven thus turning the tank to the right. When the pinions are in the position shown in Fig. 3. both crown wheels 2, 3 are driven so that the tank goes straight forward whereas in the position shown in dotted lines the tank will turn to the left. To reverse all these drives the main drive must be reversed. A slide, which is displaced according to the position. of shaft 22, 4s provided on frame 1 and has painted bands which are visible one at a time through an opening 35 in the toy housing. Symbols indicating the various actions, e.g. arrows for turning, and corresponding in colour with the appropriate bands may be arranged near the opening 35 so that the action. performed when a particular colour is visible may be determined.

Title: Process for the production of combustible gas from methanol
Inventor: DENT FREDERICK JAMES
IPC: C10K3/02
Filed: 1958-01-22
Abstract: 894,582. Combustible gases. GAS COUNCIL. May 8, 1958 [Jan. 22, 1958], No. 2205/58. Class 55 (2). A combustible gas suitable for use as town gas is made from methanol by passing a mixture of methanol vapour and steam preheated to a temperature of about 350-400‹ C. and at a pressure of 10-25 atmospheres over a nickel catalyst in a heated reaction zone, and air, at least some of which is burned in the reaction zone to maintain the reaction temperature, is utilized to produce the required final gas after removal of carbon dioxide and water vapour. Some air may be added to the gas leaving the reaction zone to effect a limited combustion of the gas, the heat thus generated and the sensible heat of the gas being used to raise steam for the process. Alternatively all the air may be combusted in the reaction zone. Carbon monoxide may be removed from the gas by converting it with steam to carbon di-oxide and hydrogen, steam being added if complete removal is required, in the presence of a catalyst before the carbon dioxide is removed from the gas. In an example a gas having a calorific value of 500 B.Th.U., and a density of 0.45, had the following composition: CO 2  2.0%, CO 2.3%, H 2  42.1%, CH 4  36.1%, N 2  17.5%.

Abstract: 1,075,152. Photo-electric inspection apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 17, 1964 [Jan. 21, 1963], No. 2495/63. Heading G1A. Apparatus for inspecting transparent or translucent containers comprises a conveyer bringing the containers to an inspection station, means for rotating the containers, means passing at least one beam of light through the containers in a direction perpendicular to the axis of the container and a plurality of detectors for said light. Bottles 2, Fig. 2, on a conveyer 1 are carried by a pocket wheel 3 through inspection stations A, B, C and D and rotated by contact with a friction strip 4. At stations A and C the bottles are inspected by 16 vertically spaced light beams from an elongated source 17 to separate photo-resistors 21 or 62. At stations B and D the bottles are inspected by a beam of light passing upwards through their bottoms. If a defect in the bottle such as dirt or a flaw is detected at any of the stations A, B, C, or D a corresponding solenoid 35, 60, 63 or 64 Fig.4, is energized to pull out a rod 39 on a timing wheel rotating with wheel 3 corresponding to the defective bottle. When such a pulled out rod reaches the switch 65, a pin 41 operates the switch energizing a solenoid 5, Fig. 2, which retains the defective bottle on the pocket wheel to be delivered to a refect conveyer 9. If no fault is detected, 5 is not energized and the bottle returns to conveyer 1. A photo-electric synchronizing-pulse generator, Fig.3 (not shown) is coupled to the wheel 16 and emits pulses which are used to gate the output of the photo-resistors to ensure that defects are only recorded when the bottles are at the inspection stations.

Abstract: 162,380. Murray, J. Jan. 27, 1920. Bending and the like. - Book - covers, cases, &c. which have curled owing to the drying of the glue in them are straightened prior to use in bookbinding by a roller bending-machine which imparts to the covers a curvature in the opposite direction which is sufficient to neutralize the curl due to the drving effect. As shown, a File A of curved covers is placed in a hopper formed of base bars A<3>, side bars A', and vertically adjustable front bars A<2>, beneath which the bottom cover is fed by pusher blocks G on a slide G<1> which is reciprocated over longitudinal guides by means of an oscillating toothed quadrant H which engages a rack G<3> on the slide G<1>. The bottom sheet passes directly to the bending-rolls D, E, F, Figs. 1 and 4, of which the rolls D, F are geared together and are positively driven, and the roll E is mounted in bearings E<2> drawn towards the rolls D, F by springs E<1> which are adjustable for the purpose of varying the extent of the bending action, so that this may be made to conform to covers &c. of different curvature. The roll F is also mounted in spring bearings in the form of bell-crank levers F<1> fulcrummed in bushes on the driving-shaft D' and acted on by adjustablesprings F<4>. The rolls D, F are formed with intermeshing collars, or square screw-threads of the same hand, so as to make the distance of the line of contact of the rolls D, E as near as possible to the line of contact of the rolls F, E, thereby diminishing the extent of the marginal portion of each cover which is not effected by the bending action. The finished covers are stacked automatically in a hopper which slopes towards the front K<1>, and towards one side K<2>.
