Title: Improvements in or relating to capping heads for bottle capping machines
IPC: B67B3/16
Filed: 1948-05-03
Abstract: 651,510. Bottle capping machines. SCOTTS ENGINEERING (NEWPORT), Ltd., and BURDIN, N. V. May 3, 1948, No. 17421/50. Divided out of 651,486. '[Class 125(ii)] A capping head of the type having a resilient member which is distorted to effect the crimping of a cap in capping bottles with aluminium foil, has a plunger member actuated by the insertion of a bottle into the capping head, the plunger actuating control means for the machine drive so that if a bottle is not fully inserted into the head, the drive is disconnected. In the form shown strip foil 12 is fed to a capping head, described in Specification 651,486 by a feeding head 18, described in Specification 637,064. The capping head has an outer sleeve 9 formed as a punch at its lower edge 11 to cut discs from foil fed into a slot 8, and an inner sleeve 17 which compresses a rubber ring 16 to crimp the disc, which is carried up into the head by a bottle top lifted therein. The capping head is operated by a lever 28 actuated at the currect moment by a spring mechanism, described in Specification 651,487. In order to clamp the disc on the bottle top a plunger 39, spring-loaded at 41, presses a rubber faced disc 43 at its lower end on to the foil as the bottle lifts towards the crimping position. This action lifts the plunger and a lever 64 bearing on its upper end, the lever 64 turning a shaft 45, this lifting a lever 48, to the end of which is attached a rod 49, which lifts and is held clear of a control pin 60 which actuates a clutch 50. If a bottle is not fully inserted into the head, the rod 49 is not lifted and trips the pin 60 so that the clutch is disengaged. The pin is located on the clutch so that after each capping stroke the machine continues to operate and prepares a cap disc for the next bottle, only stopping if a bottle is not then inserted into the head.

Title: A system of automatic train control for railways and the like
IPC: B61L3/12
Filed: 1935-06-24
Abstract: 459,133. Automatic train control apparatus. GREENLY, K. H., 31, Gledwood Drive, Hayes, and GREENLY, H., 56, Heston Road, Heston, Hounslow, both in Middlesex. June 24, 1935, No. 18045. [Class 105] Automatic train control is effected by the periodic operation of an inductor type relay on the train as the latter passes over magnetic plates spaced throughout the length of the track, such plates causing the inductor relay armature to drop by shunting the flux therefrom. Certain of the magnetic plates are moved away when the wayside signals are at danger. The periodic dropping of the armature and consequent closure of a back contact may periodically re-energize an energystorage device dissipating its energy at a certain rate ; thus with the wayside signals at danger the energy level will fall below a certain level, since the re-energization does not occur, and this fall will cause a braking of the train to ensue. The track magnetic plates are of the double form shown at M in Fig. 1 to drop the armature twice so giving two successive closures of a contact. The dynamically balanced inductor relay described in Specification 440,907, [Group XXXVII], may be used. Fig. 7 shows an energy-storage device comprising an electric condenser 20 which is periodically re-charged. and slowly discharges through a brake-valve solenoid S. If the re-charging is not effected within a certain time interval the valve V will open to apply the brakes. The brief dropping of the train relay armature effects a brief closure at the terminals 19. The first closure briefly energizes a relay A which in turn energizes a slow relay B which in its turn energizes a relay C (relay A having dropped). The immediately following second brief closure arising at the same track plate energizes a slow relay D over a front contact of the relay C (still energized over a front contact of the slow relay B). The relay A is not energized by the second closure on account of its circuit including a back contact of the relay C which relay is still energized. The slow relay D remains up for a time sufficient for a source at terminals 25 to charge the condenser 20 which thereafter discharges through a resistance and the brakevalve solenoid S in series. Instead of the re-charging of a condenser a thermal device may be re-heated while the relay D remains up, Fig. 5 (not shown), or pressure fluid may be re-admitted to a turbine driving a centrifugal governor device, Fig. 4 (not shown), and in all cases unless re-energization is effected within the required time a brake valve will open. The driver effects a starting energization by depressing a push P which is interlocked so that it can only be operated when the brakes are on. The spacing of the track plates may be determined by the gradient or other conditions of the track. The energy dissipation rate is adjusted to the class of train.
