Patent GB-115657-A (GB)
IPC: G07F17/00
Abstract: 115,657. Wiingaard, A. G. P. April 11, 1917. Clocks combined with savings boxes; stop mechanism.-In a combined clock and savings' box of the type in which the clock stops after a predetermined interval unless a coin is inserted, a cover bearing a suitable inscription is moved in front of the dial at the expiration of the interval, and is automatically withdrawn if a coin is inserted or is already present in the coin shoot. A threearmed lever l having projections 10, 11 working in slots in the coin shoot 7, and a projection 18 co-operating with a notched disk 20 on a spindle 22 of the clock train, serves to control the balance 2 of the clock and the lever mechanism for operating pivoted cover plates 25, 26. Normally, the projection 10 of the lever l holds up the previously inserted coin, the projection 18 bears against the edge of the disk 20, and the arm 13 holds a spring-controlled lever 4 clear of the balance. As the disk 20 rotates, the projection 18 engages a spring-controlled plate 23 covering the notch in the disk, and then enters the notch, the lever l moving from the position shown in Fig. 1 into that shown in Fig. 2, so that its arm 14 is withdrawn from engagement with a hook 49 on a lever 35; the lever 35 thereupon turns under the action of a spring 51 and through linkage 33, 31, and 36, 32 moves the pivoted covers 25, 26 over the dial, giving warning to the owner that it is necessary to insert another coin. The lever l has by this time been restored to the normal position, Fig. 1, by the previously-inserted coin, which, owing to the withdrawal of the projection 10, passes down the shoot and strikes the projection 11. The insertion of another coin rocks a spring-controlled lever 53, which engages an arm 52 connected to the linkage 32, 36 and opens the pivoted cover plates. If another coin is not inserted, the cover plates are opened by a pin 46, Fig. 2, carried by a gear 21 and co-operating with a cam lever 43, which is connected to a bar 41 having a pin-and-slot connexion with an arm 38 of the lever 35; at the expiration of the next interval, however, the lever l will not be returned to the normal position, the cover plates will remain closed, and the lever 4 will engage the balance and stop the clock until another coin is inserted. The pivoted cover plates 25, 26 may be replaced by a disk having radial projections adapted to be moved over the figure of the dial, or by an arrangement similar to an " iris diaphragm." Specification 12585/12 is referred to.

Patent GB-1015217-A (GB)
Title: Self-extinguishing resins containing free radical initiators
IPC: C08L25/00
Filed: 1964-03-19
Abstract: An alkenyl aromatic polymer composition containing a halogen flameproofing agent also contains a free radical initiator which is a sulphenamide, a hydrazone, an organic disulphide, an azo compound, a quinone imine, or a -a 1-diphenyl-a -methoxybibenzyl as a flameproofing adjuvant.  In the examples 28 different free radical initiators and 10 different halogen flameproofing agents are used. Polymers exemplified are polystyrene, polyvinyl toluene, and copolymers of styrene with a -methyl styrene, acrylonitrile or butadiene.  Other polymers specified include polychlorostyrene. The adjuvants are incorporated in the polymer composition by dissolving the ingredients in a common solvent, e.g. methyl chloride, and then rapidly evaporating the solvent to give a foamed structure; by impregnation under pressure of polymer granules with the adjuvants in aqueous emulsion (and optionally with a blowing agent such as n-pentane if a foamable resin is required); or, in the case of those adjuvants that do not generally inhibit polymerization, by polymerization of the alkenyl aromatic monomers in the presence of the adjuvants.

Title: Improvements in or relating to tensioning devices for machines for forming tubes of paper or the like
IPC: B31C1/00
Filed: 1920-11-26
Abstract: 180,972. Wade, H., (National Paper Can Co.). Nov. 26, 1920. Feeding webs.-Relates to means for applying tension to paper strips fed into machines, such as are described in Specification 180,707, [Class 99 (ii), Pipes, tubes, &c.], for forming paper tubes by winding the strips on to a rotating mandrel. According to the invention, (1) the paper strip 6 in its passage to the mandrel 2, Fig. 2, passes between a driven roller 95, Fig. 7, and a free roller 96. The peripheral speed of the roller 95 is less than that of the mandrel, so that it exerts a drag on the strip. The roller 95 is connected to its driving shaft 101 by a regulatable friction clutch 100, whereby the amount of drag may be regulated by the slipping of the roller relatively to the shaft. (2) The paper strip is guided on to the mandrel by a spring-pressed plate 117 and a foot 125 on a pivoted arm 118. At the moment that the end of the strip passes from between the rollers 95, 96, the arm 118 is raised by a special cam device,. acting through a spindle 135, and the strip is nipped between the plate 117 and the foot 125. Tension is thus maintained on the strip right to the end of the feed.
