Abstract: 322,164. Parry, F., and Molins Machine Co., Ltd. Aug. 22, 1928. Parallel rails and pushers on endless chains; pushers and abutments, means for projecting and retracting. - Conveyers, such as are used in wrapping-machines for moving an article through the machine while the initial folding operations take place, are arranged so that the pusher pieces are caused at certain points in the travel to move in the reverse direction, so as to be disengaged from the open end of the partially formed packet, and thereafter are again moved in the normal direction. The reversing movement is caused by rotatable means, such as sprocket wheels, axially fixed and arranged at intervals. As shown, pusher members 1 are mounted on carriages 2 over endless double roller chains 3 guided by sprockets 5 - - 9. During the horizontal run, rails 13, 15, 16 guide rollers 12, 14 on the carriage and, at the end of the run, when the member 1 is to be disengaged from the open end of the packet, a slot 11 on the forward end of the carriage embraces the shaft 18 carrying the sprocket 6. The rear roller 12 has meanwhile cleared the rail 13 and the carriage is rotated in a clockwise direction into the position shown in Fig. 5, and moves downwards until the rear slot 11 embraces the shaft 20. This causes the travel of the member 1 to be positively reversed in direction. The carriage is again rotated about the shaft 20 prior to moving along the return run.

Abstract: 259,223. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Smith, H. B.). Oct. 1, 1925, [Convention date]. Transformers.- Deterioration of the insulating medium in high tension transformers is avoided by the provision of shields and toroidal members so shaped and proportioned with regard to the potentials to which they are subjected as to prevent the accumulation of corona-forming or incipient-ionizing potentials. In a transformer in which the low tension winding 5 and high tension winding 3 are arranged concentrially on the middle limb of a core 4, the shields are in the form of annular members 7 connected to certain of the toroidal members 6 connected to or forming the outer turn of the high tension winding sections. The upper part of the high tension winding is formed of tubular conductors 8 arranged to present a curved contour and is connected to a terminal 9, Fig. 6, the other end being connected to the casing at earth potential. The potential gradient from the terminal 9 to the casing is determined by toroidal members 13 of successively decreasing cross sectional diameter in an outward direction and connected through concentric shields 11 to the shields 7. In a modification, Fig. 7, the terminal 9 passes through a larger opening 31 in the casing 2, and the shields 32 terminate in toroidal members 33 arranged and proportioned as shown. Fig. 8 shows the invention applied to a transformer having a rectangular core 31 carrying low tension winding sections 32 surrounded by high tension winding sections 36, the latter being connected to metallic shields 37, 35 separating the sections from each other and from the low

Abstract: 1299254 Electronic watches P VOGEL 19 May 1970 [29 May 1969] 24247/70 Heading G3T In the inoperative position (as shown Fig.1), of a time setting control member 7, for an electronic watch a main oscillator 5 for the watch drive is energized from a source 1 via a switch 8 and feeds a counter 2 and display device 3 via a frequency divider 6. When the member 7 is depressed against a spring bias 12 for time setting it causes the main oscillator and divider to be disconnected from the power source 1 by the switch 8 and a switch 9 to set the counting device 2 and display 3 to zero i.e. to a state corresponding for example to 12 o'clock. At the same time the switch 8 connects a uni-junction transistor time setting oscillator 4 (detailed in Fig.3 not shown) to the source 1. The oscillator 4 has an output frequency which is always higher than that of the main oscillator 5 and which is progressively increased as a wiper 10, attached to the control member 7, slides across a resistor 11. The setting oscillator output is delivered to the counting device 2 and the time setting speed is selectively and continuously variable as a function of the position of the control member 7.

Title: Improvements in or relating to charges for gas pressure operated blasting devices
IPC: C06B31/28
Filed: 1936-09-04
Abstract: 481,166. Blasting-charges. TAYLOR. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 4, 1936, No. 24266. Addition to 453,210. [Classes 9 (i) and 9 (ii)] Relates to a charge for blasting-devices as claimed in the parent Specification, in which the gas-evolving composition contains a proportion of combustible carbonaceous ingredient. According to the invention, a substantial proportion of this ingredient is segregated from the remainder of the gas-evolving composition in coherent form and is arranged at least partly in the neighbourhood of the igniter. Thus it may be in the form of a waterproofed paper or cardboard tube with the igniter located therein. The-igniter may consist of a 30 to 100 grain powder fuze, an electric powder fuze as used for igniting black powder pellets, a safety electric igniter as described in Specification 431,950 or a small smokeless powder or cordite charge ignited in turn by a fuzehead or percussion cap. An extended tube of the carbonaceous material suitably sealed may be employed wholly or in part as a container for the active charge in the igniting element or, when an electric fuze is employed, one or both of the lead-wires may be passed through the tube from the igniter to their terminals in the device. The proportion of combustible carbonaceous ingredient distributed throughout the gas-evolving composition should not exceed 4 per cent by weight of the ammonium nitrate and preferably does not exceed 3 per cent whilst the segregated ingredient and the igniting element together should require at least about 45 grams of ammonium nitrate for their oxidation. Specification 430,258 also is referred to.
