Abstract: 683,467. Making paper bags. PAPER SACKS Ltd., and ROBINSON, P. G. May 18, 1950 [May 20, 1949], No. 13563/49. Addition to 623,313. Class 94(ii) The invention described in the parent Specification is modified by assembling the multi-ply bag lengths with their ends flush and the tongue on the innermost or other ply projecting beyond the flush edges, and either infolding the valve in each multi-ply length so that the tongue extends inwardly beyond the other plies at the valve to form a flexible closing member, and closing both ends of the bag tube by stitching a reinforcing strip across them, or folding both ends of the tube to form a block bottom closure with a valve at one corner and securing by stapling or by adhesive. Fig. 1 shows part of the web providing the ply from which the valve extension tongue 4 is obtained from transverse lines of perforations 3a, 3b and short longitudinal slits 4a, a corresponding recess being obtained at the tail end of the preceding bag length. When this ply is used as the innermost ply of a bag the recess 4 at the bottom is exposed to the interior of the bag and, to avoid the sifting of the contents between the plies at the recess, the margins thereof are pasted in known manner. Similar interply pasting may be employed at the valve corner. Fig. 4 shows a bag tube length with the overlapping longitudinal margins 5 of the webs secured together adhesively in known manner, and the valve corner infolded so that the valve tongue 4 extends beyond the margin 6 of the other infolded plies. The bag is subsequently machine stitched across the flush ends through reinforcing strips 7. Gusseted bags are produced by passing the webs through tubing machines provided with gusset-forming means. Fig. 9 illustrates a stage in the forming of a block bottom bag, the subsequent folding of the margins 9a, 9b being along the.chain lines 10. The width of the tongue 4 should be not less than the distance between the lines 10. In a modification, Fig. 7, (not shown) the tongues 4, instead of being of rectangular form, are bevelled at the corners and provided with short slits along the lines of fold to facilitate folding.

Title: Improvements in switch operating mechanism for electric signalling circuits
IPC: B66B19/06
Filed: 1938-05-10
Abstract: 514,558. Snap-action switches. SPRAY, P. C. J. May 10, 1938, No. 13897. [Class 38 (v)] The handle A of a switch for mine signalling drives an anxle B on which is fixed a locking disc E, Fig. 3. Mounted on a spindle M is a lever L which carries loosely a locking roller G. The lever L carries a weight P just insufficient to counterbalance the lever L so that when handle A is turned clockwise, so that arm O releases lever L, the lever slowly turns to cause roller O to jam between disc E and surface H to lock the parts against further movement. This is to insure that handle A is moved quickly to the completion of its stroke. Also after one operation it is impossible to move the handle to the on position again until it has been moved back to the off position when arm O lifts the locking lever A second arm Q also lifts the lever L at the end of the operative stroke. Instead of the roller G a pawl may be used to engage teeth on disc E, and the delayed engagement of the locking means may be provided by a dashpot. The axle B carries a contact roller R, Fig. 4, which has a pin R<1> connected by springs S, S<1> to pivoted levers T, T<1>. Movement of handle A towards the on or off positions causes a cam U to move the corresponding lever T or T' to strain the appropriate spring S, or S' to move the roller to the on or off position. During the straining of the springs, the roller R is restrained by the engagement of one or other of pins R<2>, R', Fig. 5, with catches V, V' which are tripped on completion of the respective movements either by an arm W on an axle B or by a cam W<3> engaging an arm W<2>.

Title: Electrical musical instruments with thermionic valves
IPC: G10H5/02
Filed: 1936-05-16
Abstract: 474,838. Electrical musical instruments. SOC. HOLDING E.S.L.A.M., and POTENCIER, J. May 16, 1936, No. 13949. [Class 88 (ii)] An electrical musical instrument comprises continuously oscillating valves, one for each note of the scale, separate amplifiers for each stop-pitch (8-ft., 4-ft., &c.) on each keyboard, and intermediate coupling valves one for each note of each stop (of different pitch) on each keyboard. High tension is only applied to the anode of an amplifier on drawing the corresponding stop, and to the anode of a coupling valve only on depressing the corresponding key. The Figure shows three continuously oscillating valves V, V<1>, V<11>, corresponding to three scale-notes successively an octave apart. Coupling valves V1, V<1>1, V<11>1' correspond to the same notes at 8-foot pitch, and V<1>4, V<11>4, V1114 to the same notes at 4-foot pitch, on keyboard I. Coupling valves V2, V<1>2, V<11>2 correspond to the same notes at 8-foot pitch on keyboard II. The 4-foot coupling valve V<1>4 is connected to continuously oscillating valve V<1>, V<11>4 to V<11>, and so on. Depression of a key T1 of keyboard I applies high tension from a source B1 to the anodes of coupling valves V1, V<1>4 and sounds an 8-foot and a 4-foot note in loudspeaker means, respectively through amplifiers L1, L<1>1 when the high-tension stop switches J1 J<1>1 of these amplifiers are closed. Expression on this keyboard is controlled by potentiometer P1. Resistances R1 and condensers C1 connected to the coupling valves are selected to produce an attack similar to that in pipe organs. On releasing a key T1 after depression, condenser C1 discharges through a resistance R3 connected to the negative pole 'of heating source B, obviating ground noise.

Title: Process for the production of concentrated sulphur dioxide
IPC: C01B17/60
Filed: 1936-05-19
Abstract: In recovering sulphur dioxide by treating gases containing it with a mixture of water and organic bases and expelling the absorbed sulphur dioxide by heat, with the addition to the absorption mixture of an auxiliary substance as set forth in Specifications 435,116 and 443,314, the process is controlled by the addition of the auxiliary substance in an amount sufficient to prevent the mixture exceeding a degree of acidity corresponding to the acidity of the bisulphite or bisulphites of the particular organic base or bases employed, at least during the sulphur dioxide expulsion stage, so that the autoxidation of sulphur dioxide to sulphur is prevented.  Suitable auxiliary substances are oxides, hydroxides, carbonates, sulphites, or other salts of a weak acid and an alkali metal, including ammonium, or magnesium or an alkaline earth metal.  The auxiliary substance may be added initially in sufficient excess to operate during several cycles. Suitable organic bases are toluidines or xylidines, especially a mixture of crude xylidines.
