Filed: 1950-05-25
Abstract: 688,645. Mechanical make-and-break switches; gas blast circuit-breakers. SCHILLING, A. H. May 25, 1950 [May 27,1949; March 22, 1950; April 19, 1950; April 19, 1950; April 19, 1950; April 19, 1950], No. 13174/50. Class 38 (v) Apparatus for mechanically converting electric currents comprises at least one electrode which is rotated uniformly in one direction and is brought into rolling contact with at least one counter-electrode, periodic interruptions being made in the contact by cutaway portions of the electrodes coming into the contacting position, an intermittent current passage through the electrodes thereby being obtained. Fig. 1 shows a simple form in which the circuit is made at ignition electrodes 11, 12, which together with the main electrodes 1, 2, are rotated by a motor in the directions shown. The circuit is broken when the trailing portions 5, 6 of the electrodes separate, any arc caused thereby being extinguished by gas blasts through nozzles 7, 8. Several such electrodes may be arranged in series, Figs. 8, 9 (not shown), and the rolling electrode may co-operate with a stationary electrode, Figs. 11 and 12. In this form, the stationary electrode 50 is circular and the moving electrode 59 is pivoted at 54 to a plate 56 which rotates about an axis 57 concentric with the electrode 50. The electrode 59 is caused to rotate about pivot 54 by the engagement of a gear wheel 58, on said pivot, with teeth 53 arranged on the mounting 47 of electrode 50. In a further modification Figs. 13, 14 (not shown), the engaging electrode surfaces are bevelled, the planes of the two electrodes being at right-angles. The Specification also refers to the use of resilientlymounted contacts, adjustment of the electrodes for timing purposes, and the use of magnetic blow-out arrangements, together with many details of structural modifications of these and other items.

Title: Improvements in or relating to evaporators
IPC: B01D1/02
Filed: 1925-05-20
Abstract: 236,901. Griscom-Russell Co., (Assignees of Brown, S.). July 14, 1924, [Convention date]. Bulk evaporators.-An evaporator has a heating-element composed of a continuous tube wound into a single coil of flat convolute form, and the plane of the coil is disposed horizontally, and the tube is flattened verticallv in cross-section. The use of flattened tubing causes the distance B between adjacent tube-faces to be greater than in corresponding coils of tube of circular cross-section, thereby minimizing the risk of scale bridging the space B. Alternatively the inter-tube distance may be made the same as in a coil of tube of circular section, the number of convolutions being increased. The flattened tubes may be of elliptical, parallel-sided, diamond, or hollow-sided cross-section. Specification 138,870 (as open to inspection under Sect. 91 (3) (a)), [Class 64 (iii), Surface apparatus &c.], is referred to.

Abstract: 308,917. Wellman, C. P. May 8, 1928. Paper bags, making.-Relates to machines for making bags and linings therefore of the kind in which each of a series of mandrels circulating in a continuous path encounters one or more blanks which are folded about the mandrel by folder mechanism. According to the invention the folder mechanism is arranged to operate on the receptacles on the mandrels during the travel of such mechanism in the same direction, and at the same speed, as the mandrels. As shown, the mechanism is applied to the machine of Specification 270,443, [Class 18, Boxes &c.], and comprises sets of folder blades 181,190 carried by slides 175, 176 in blocks 145 connected to a chain 150 travelling in a horizontal plane with one run in proximity and parallel to the path of the end faces of the mandrels 5 on the chain 57 which travels in a vertical plane. The pairs of blades 181 are pivoted at 182 to the blocks 145 and carry rollers 183 held against cam faces 184 on the slide 175 by springs 185, the slide carrying a roller 188 adapted to engage a cam groove in a channel member 162 projecting from a channel member 160 guiding the blocks 145; the folder blade 190 is carried by the slide 176 connected to a spring and carrying a, roller 193 adapted to engage an adjustable cam 163. The chain 150 is carried by sprockets 153, 154, the sprocket 153 being geared to the driving sprocket of the mandrel chain 57 and being adjustable to enable the mandrels and folding blades to be properly aligned. As a mandrel carrying a blank folded around it arrives in alignment with a folder assembly, the cam 162 depresses the slide 175 and the cam faces 184 force the blades 181 towards one another to form the tucks f<1>, f<2> at the end of the folded blank and then the cam 163 depresses the slide 176 to force the blade 190 down and turn the fold f<3> over the blades 181 which still hold the tucks f<1>, f<2> in position against the end face of the mandrel. Further movement of the mandrel and folder mechanism causes the blades 181' to be withdrawn and the mandrel is then rotated and passes to a stationary folder 7 which folds in the fourth fold f<4>, the folder 190 being raised by its spring and the folded blank being then carried past the heater 155 which fuses the maxy or resinous material carried by the blank material; the receptacle is finally carried past a cooling and pressure plate which holds the parts until the sealed seams are set. The blades are slightly resilient and the edge 192 of the blade 190 is curvd so that it is concentric with the axis of the mandrel at its lowest position and so does not interfere with the turning movement of the mandrel.
