Filed: 1937-11-18
Abstract: 505,914. Packeting - machines. COLEMAN, A. M., BATER, C. C., and LEE, G. A. Nov. 18, 1937, No. 31808. [Class 94 (i)] In a machine for closing packets, such as small bags of tea, the bags 'are fed from the closing mechanism on to a tray with a number of compartments, each compartment receiving a pre-determined number of bags. The tray is moved a step when each compartment is filled, and when the last compartment is filled, the machine is stopped. The filled bags are placed on a conveyer 7 between a vertical wall 5 and a retaining rib 6 and the upper part of each bag is flattened by a beater 10 comprising a reciprocating bent wire member. The upper parts of the bags are next engaged between pressure belts 14, 15, Figs. 1 and 4, while a folding guide 17 co-operates with a rib 16 to turn over the top. A wheel 20 applies adhesive to the underside of the fold, which is pressed on to the wheel by a spring 22 passing through a slot in the guide 17. Rollers 18, 19 effect closure by crimping or pressure, and a plunger 25 forces the packet into a compartment 26 in a tray. The packet may be forced into position in front of the plunger by a jet of air. A feeler 27 is arranged to be moved by each packet to allow the plunger 25 to operate after an interval long enough for the packet to be moved into the discharge chamber 24. The sliding rod 34 carrying the plunger 25 is coupled to an operative rod at the appropriate times by means of a trigger 36 adapted to engage with a recess. ,The number of packets to be fed into each compartment can be regulated by engaging one of a series of pawls 55 ... 59 with a corresponding toothed wheel 60...64. The pawls are actuated from the slide 34 by a crank 49, and by means of selecting the wheel with the requisite number of teeth, a shaft 65 is turned to actuate trip mechanism to allow the tray to move a step when the compartment is full. The shaft 50 carrying the crank 49 actuates a counter 53. When the last compartment has been filled, the machine is stopped by the tray engaging a switch at the end of its travel.

Title: Improvements relating to electron discharge devices
IPC: H01J21/06
Filed: 1936-11-27
Abstract: 473,579. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Nov. 27, 1936, No. 32554. Convention date, Feb. 4. [Class 39 (i)] An electron-discharge device comprises a containing vessel in the form of a tube closed at one end, a metal disc member sealed over the other end to form, either alone or together with a vitreous cap sealed over its outer face, a closure for the tube, a unitary electrode structure comprising a cathode and a plurality of grids coaxially disposed in the tube and carried by the metal disc or the vitreous cap, and a cylindrical plate electrode coaxial with the unitary structure and supported from the wall of the tube with a leading-in conductor passing through the wall of the tube. In the form shown in Fig. 3, a metal disc 11 covers the end of a glass cup 10 and carries the cathode and control, screen and suppressor grids. The leads to these electrodes pass through insulating beads 17 sealed into the disc 11, with the exception of those to the suppressor grid 28 which are welded to the disc and carry top and bottom screens 44 and 32 respectively. An annular backing ring 12 of glass is sealed to the outside of the disc 11 and makes the sealing point more rigid. The anode 15 is supported by the lead 13 which passes through the envelope at 14. The cathode heater surrounds and is connected at one end to a central support rod 40. In a modification, the disc 112, Fig. 9, is formed with an inwardly extending flange 144 acting as a shield and the electrode leads are carried by a dish-shaped glass member 111 sealed over the end of the tube. The mica spacer 115 fits into the flange 114, which is close to the anode 113 and of the same diameter. In another form, the disc 211, Fig. 13, is continuous except for apertures through which pass the electrode leads, and a mass 233 of glass covers the outside of the disc and carries the leads. The glass mass renders the disc rigid and prevents undesirable flexing of the disc under changes of external pressure. The suppressor grid is connected directly to the disc by metal eyelets 232 engaging its support rods 227. The mica spacer 220 touches the envelope and is supported by an annular metal shield 228 welded to the rods 227, as is also the upper shield 230. The anode 213 is spaced from the envelope by springs 218. In all constructions the disc member may seat upon an external screening member. The sealing may be effected by heating the disc by high-frequency induction, as described in Specification 474,706, [Group XXXVI].

Abstract: 816,667. Diaphragm vibrators. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 21, 1957 [Oct. 26, 1956], No. 32802/57. Class 13. [Also in Group XXXIX] In a vibrator actuated by alternating current an iron core 2 (Fig. 1), having a winding 3, is mounted in a soft iron pot 1, and a disc armature 4 secured by a screw 6 engaging in the tapped bore of the core 2 is urged away from the edge of the pot by a spring washer 5. Projections 8 (Fig. 2) on the periphery of the washer 5 engage in corresponding notches 9 in the wall of the pot, and the arms 10 project inwardly and upwardly so that their ends press against the armature 4. Varying the amount that the screw 6 is screwed into the core 2 varies the airgap and hence the amplitude of oscillation of the armature 4. To ensure maximum sound output it is arranged that when the arms 10 are depressed by the downward moving armature 4, the ends of the projections 8 are rocked upwards to engage the edge of the armature 4 and reset it to its initial position as quickly as possible.

Title: Improvements in or relating to binary counting circuits
Inventor: HALTON DONALD
IPC: H03K23/00
Filed: 1960-09-24
Abstract: 913,781. Counters. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 30, 1961 [Sept. 24, 1960], No. 32886/60. Class 106 (1). In a binary counting circuit in which each bistable element except the first is controlled by all the preceding elements the outputs from the set sides of an odd-numbered element and of the succeeding even-numbered element are combined in a coincidence gate, the output of which controls the next pair of elements through a lowimpedance device. Each element is made up of a pair of crossconnected transistors, Fig. 1, such that TXO or TX1 conducts, according to whether the element is set to 1 or 0, respectively. Input signals are applied to IL1 or IL0 followed closely by strobe pulses on SL1, SL0 Feed-back from the respective collectors ensures that an input to a particular side of the element will be ineffective if that side is already set.  The counter shown in Fig. 2 is a hybrid cascade and ring counter with driving pulses applied at DPL to all stages although the first element A controls all later stages. The counter operates in pure binary manner with the output of each odd-numbered follower circuit F1, F3, F5 providing a dive for the following pair of toggle circuits until the 7th and 8th circuits are reached. The even-numbered follower circuits F2, F4, F6 operate one strobe pulse earlier than the corresponding followers F1, F3, F5. When toggle H is first set, F6 aids in setting up toggle X but the delay in X prevents it producing an output until after the appropriate strobe pulse has ended. Toggle X includes a feed-back which restores it at the next strobe pulse. X thus acts to prevent misoperation of later toggles by the build-up of delays which might occur if more than three follower circuits were used in series. A single follower is used in respect of each subsequent pair of toggles.
