Abstract: 286,325. Martin, H. E. Sept. 29, 1926. Packeting by wrapping-up.- In machines, for wrapping caramels and the like, and of the type described in Specification 203,370, all the folding members are stationary, and complete the wrapping of the caramel except for the turning down of the top flap and the final closing tabs before ejection into the delivery channel takes place. The articles 1, Fig. 1, are fed along a channel 3 by a belt 2, and are thrust, with a wrapper 6, by a plunger 7 into a recess 4 in an oscillatable arm 5. The wrapper is thereby folded into the form shown in Fig. 3, stationary folders 8 causing the formation of lugs 9 and folding slots 11 accommodating lugs 9<a>. The extending portion 12 is temporarily supported on a folder 10. The arm 5 now swings downwards, the folder 10 turns up the portion 12 and the lower edges of the slots 11 turn up the lugs 9<a> to produce the formation shown in Fig. 4. During the further descent of the arm, inclined slots 15 turn in the flaps 14, the wrapper then being disposed as shown in Fig. 5. When opposite the delivery trough 16, the packet is thrust therein, the portion 17 being turned down by the lid 18 and the final flaps 19, Fig. 6, laid upon the top by stationary converging folders 20 to complete the wrapping. The folders 20 are formed integrally with the lid 18, which rests by means of pins 22 in slots 23 in the side frame. Springs 25, 26 cause the lid to exert slight pressure on the packets.

Patent GB-241772-A (GB)
Abstract: 241,772. Beaumont, J. H., (Naamlooze Vennootschap Instrumentfabriek en-Handel voorheen P. J. Kipp & Zonen). Jan. 22, 1925. Electromagnetic current meters; electrostatic meters.-In a galvanometer or other electrical measuring instrument of the vibrating string type, the vibrations of the string are measured by attaching thereto asymetrically a small mirror possesing inertia or damped by the medium in which it is situated, and observing the consequent rotary movement of the mirror. A stretched string 2 carrying the current is positioned between the poles 1 of a magnet. A small mirror 4 is fixed asymetrically to the string. By the action of the inertia the mirror rotates about an imaginary axis 6. This motion is used to reflect a beam of light and form a luminous band the length of which is proportional to the amplitude of movement of the string. To vary the damping the pressure of the medium surrounding the string may be varied, a little wing may be fixed to the string, the system may be immersed in a liquid, or the strength of the field may be varied. By suitably choosing the mass of the mirror and the length, tension and material of the string the whole system can be tuned up to a given frequency.

Abstract: 881,885. Ignition coils. ELECTRIC AUTOLITE CO. July 14, 1959, No. 24187/59. Drawings to Specification. Class 38 (2). A ignition coil for an engine ignition system (see also Group XXVII) is so arranged as to provide a very close coupling coefficient between the primary and secondary windings and the induced voltage in the primary winding is materially decreased so as to substantially reduce the duration of the objectionable arcing across the timing contacts when the energizing current is interrupted. The core of the coil may be of high-permeability steel or of material capable of carrying a very high magnetic flux per unit of cross-sectional area. A core produced by a multi-turn winding of grain-oriented high-percentage silicon steel ribbon coated to separate and hold in position its turns may be used. The primary and secondary windings are arranged in concentric relation and preferably positioned over the air gap provided in the substantially closed magnetic core. The coil should include a primary winding made for high input energizing current and have a relatively low inductance and utilize comparatively few turns with a very high turn ratio between its primary and secondary windings. The core is preferably C-shaped. Further details are given of the windings and voltages employed and dimensions of the core gap.

Patent GB-244781-A (GB)
Abstract: 244,781. National Cash Register Co., (Assignees of Arnold, C. H.). Dec. 17, 1924, [Convention date]. Cash registers.-In apparatus such as that described in Specification 227,852 (as published under the International Convention) wherein the insertion of a cashier's key enables the machine to be freed for operation and the key sets type for printing the cashier's characteristics, the type setting racks are directly engaged with the key so as to be moved positively thereby both outwardly and homewardly. The setting racks 33 slidable on studs 24 have turned-down ends 32 to be engaged by the differential characterizing lugs 31 of the cashier's key 30 and in the construction shown in Figs. 1 and 3, the guide slots 40 in the racks are shaped at one end to co-operate with one stud 34 in such a way as to lower the right hand ends of the racks as these are pushed to the left when the key is thrust in. The downturned endls 32 of the racks are thus caused to enter apertures 55 in the key and so form a positive connection ensuring the return of the racks upon withdrawal of the key. The racks tend to remain raised by the action of spring plungers 43 and are guided at their ends 32 by slots in a bracket 65. In another arrangement shown in Fig. 11, the racks are locked in home position by the bent end 89 of a spring-influenced lever 86 engaging notches 85 in the racks. The inward motion of the key causes through its bevelled end 95 the upward rocking of a lever 91 and consequently of the lever 86. In a further modification the racks are not capable of vertical movement but the key slides at an angle so as to effect the positive con. nection with the racks. When the key is in place plungers 77 enter notches 76 in the key and thus permit rotary movement to the tumbler barrel 74 connected by a link 72 with the release shaft of the machine.
