Title: Improvements in circuit arrangements comprising a mercury rectifier having an ignition electrode
IPC: H01J13/48
Filed: 1937-09-17
Abstract: 502,255. Converting. GENERAL ELECTRIC CO., Ltd., and PRINZ, D. G. Sept. 17, 1937, Nos. 25302/37 and 14689/38. [Class 38 (ii)] In a circuit arrangement, including a dis. charge device having an ignition electrode, in which the circuit constants are such that a short ignition impulse is insufficient to effect ignition, provision is made whereby control is obtained either by altering the circuit constants sufficiently to render the ignition impulse effective, or by lengthening the duration of the ignition impulse. Due to the inductance 7, 8, Fig. 1 (14689/38), and capacity 6 in the circuit, an oscillatory discharge commences when the ignition electrode 9 receives an impulse, and under certain conditions the discharge current reduces to zero after the ignition impulse has ceased, and effective ignition fails to take place. Various ways of adjusting the circuit constants are described. The inductance 8 may be varied by an adjustable air gap in its core, or by means of a presaturating winding or by varying the number of turns. Alternatively, damping resistances may be connected in circuit to reduce the oscillatory component. This may comprise a thermionic valve, the effective resistance of which is adjusted by means of grid bias. The capacity in circuit may be varied to increase the frequency of the oscillatory component. To increase the duration of the ignition impulse, a " back up " circuit may be provided comprising a D.C. source 10, Fig. 1 (25302/37), connected through a control switch 9 to an auxiliary electrode 7, to give a sustained discharge when an ignition impulse is given to electrode 4. Opening the switch 9 renders the discharge device inoperative. In a modification of this, a condenser, connected between the cathode and electrode 7 through the resistance 8, is charged from the battery 10 through the switch 9 and a further resistance. In a further modification, the switch 9 is replaced by a light-sensitive cell. The arrangement may be provided with a relay to operate under fault conditions.

Abstract: 730,892. Transistor mufti-stable-state circuits. STANDARD TELEPHONES & CABLES, Ltd. Oct. 9, 1952, No. 25326/52. Class 40 (6). [Also in Group XIX] A multi-stable-state circuit comprises two transistors, each of which has a currentamplification factor of such value and a resistor in its base circuit of such value that by virtue of positive feed-back it has only two stable states, in one of which it is conducting and in the other of which it is non-conducting, and an interconnection from one electrode of one transistor to a like electrode of the other transistor such that on applying a pulse to a transistor in its non-conducting state to cause it to assume its conducting state, the other transistor, if it is already conducting, is caused to assume its non-conducting state. In the circuit shown in Fig. 2, the collectors of the transistors are interconnected by condenser Cl, while the emitters are connected to bias sources through current limiting resistors R1, R2. Control pulses are applied through condensers C2, C3 to the bases of the transistors. The circuit is initially set so that one transistor is conducting while the other is not. On the application of a short negative pulse to the base of the non-conducting transistor it is caused to conduct, thus applying a positive pulse through Cl to the other transistor and switching it off. By applying a second negative pulse to the base of the other transistor, the original state of the circuit can be restored. The interconnection between collectors may also be achieved by using a common collector circuit resistor for the two transistors. In alternative circuits, Figs. 4 and 5 (not shown), the bases and the emitters are interconnected respectively. When short-duration triggering pulses are used so that the pulses produced at the collectors persist after the end of the triggering pulses, the bases may be pulsed together, the application of a negative pulse to the base electrodes in parallel causing a change of state independently of which transistor is conducting and which is non-conducting. Fig. 3 shows a circuit having a single triggering pulse input P but designed to operate with pulses of long duration. The negative-going edges of the input pulses are passed by the rectifiers. MR1, MR2 and differentiated by circuits C5, R5 and C6, R8 to produce short negative pulses at the transistor base electrodes. However, due to the large-valued resistors, R6, R7, the positive-going edges of the input pulses are prevented from producing corresponding positive pulses at the bases Fig. 6, (not shown), shows a seale-of-two counting chain, employing a plurality of circuits of the type shown in Fig. 3, an output taken from an emitter electrode of one transistor pair being connected through a wave-shaping circuit comprising a limiting transistor amplifier to the input P of the succeeding transistor pair.

Each of several grippers for engaging bottles or the like comprises a pair of vertically sliding rods 5, 6, Fig. 2, supported from plates 1, 20 so that they may be moved relatively to one another to cause a gripper to grip or release the article. Each gripper shown in Figs. 2 and 4 comprises an inverted cone 13 carried by the rod 6 to rest on the top of the bottle and a sector 8 carrying a fork 7 for engaging beneath the bottle neck and pivoted about trunnions 9 on the rod 6. When the apparatus is lifted by the support 1 links 10 on the rods 5 turn the forks 7 out of engagement.with the necks of the bottles; when instead the support 20 is raised the forks 7 lift the bottles. Each rod 5 is formed with a swell 17, Fig. 2, by which it is centred in holes 4 and carries a forked arm 14 which engages a guide 15 to prevent the sleeve 5 from turning. The rods 6 terminate in inertia blocks 18 formed with tapered lower ends for engaging feet 19 in the support 20. A flared skirt 2 depends from the support 1. In the construction of Fig. 5 the bottle neck is gripped by dogs 40 pivoted on a wire ring 39 in a disc 36 carried by a rod 31 and adapted to rest on the top of the bottle, and the dogs are moved inwardly to grip the bottle by upward movement of a cup 48 carried by a sleeve 32. In an alternative construction the dogs 40 are moved inwardly to grip the bottle by downward movement of a cup similar to the cup 48 but with its cam surfaces 49 oppositely inclined. In such a construction the dogs may be formed by slits dividing the wall of a cup formed of resilient material. The dogs 40, Fig. 5, may have forked portions for engaging beneath the neck of the bottle.

Filed: 1932-09-12
Abstract: 390,062. Diaphragm gas-pressure regulators. GAWA PATENT-VERWALTUNGS-AKT.-GES., Schaffhausen, Switzerland.-(Assignees of Deutsche Gasgerate Ges. ; 9, Kottbuser Strasse, Berlin.) Sept. 12, 1932, No. 25411. Convention date, Sept. 11, 1931. [Class 135.] A diaphragm gas-pressure regulator suitable for high pressures has a coupling device connecting the valve b in the inlet a<1> and the regulator diaphragm f, which device is automatically released by a predetermined pressure acting on the centre part of the diaphragm f, so that the movements of the diaphragm f thereafter have no influence on the valve. The coupling device comprises adjustable spring- pressed detents k normally preventing relative movement between a spindle g connected to the diaphragm f and a coaxial sleeve h coupled to the valve b by a three-arm lever d pivoted at d<1>. The detents k slide in cylindrical guides h<1> connected by brackets h<2> to rings h<3> clamped to the diaphragm f. A collar g<1> prevents downward movement of the spindle g with respect to the sleeve h. During normal pressure regulation when gas is being drawn off at the outlet a<2>, weights G and an adjustable spring m tend to open the valve in opposition to the gas pressure on the part of the diaphragm f outside the rings h<3>. If, when the discharge of gas ceases, the valve b fails to close on its seat b<1>, the excessive gas pressure on the centre part of the diaphragm f causes a conical part g2 of the spindle g to push back the detents k out of holes or recesses in the sleeve h so that their pointed ends k<1> alone remain in slots h<4>. The valve b then closes on a second seat b<2> under the influence of the weight G and spring m. An auxiliary diaphragm i of greater area than the centre part of diaphragm f is clamped in the walls of a chamber i<1> removable during the normal operation of the regulator and is connected to the spindle g rigidly or so as to have slight relative movement thereto. The greater area of this diaphragm i causes it to operate the coupling device immediately any leakage in the diaphragm f occurs. The rings h<3> support loading weights G<1> for the diaphragm f.

Abstract: 941,876. Feeding webs. AGFA A.G. July 3, 1962 [July 4, 1961], No. 25475/62. Heading B6B. [Also in Division G2] A web of material such as photographic paper is obtained in contact with a conveyer belt as it passes round a roller by providing a magnet in the said roller, and attaching magnetically responsive means to the leading edge of the web. Fig. 1 shows a drying machine for photographic paper, although the device is applicable to other photographic processing machines. As shown, the exposed and developed strip 11 is fed into the nip 11b between an endless belt 4 and a heated drum 1. It is carried round in contact with the drum, and leaves it at the top, where the belt traverses a roller 10. The strip or web 11 would tend here to fall away from the belt, but it is desired that it should remain in contact with the belt so as to be conveyed round roller 10 and on to a take-up reel 12. As shown in Fig. 2, two pairs of magnetic discs 14, each pair separated by a brass disc 15, are fitted on the shaft 13 of roller 10 (since in fact two webs 11 may be conveyed simultaneously). The leading edge of the web has attached thereto a strip 25 of iron or other magnetic material (Fig. 5). Thus the leading edge is retained in contact with the belt as it passes round roller 10. Co-operating with roller 10 is a pressure roller 18 having a soft iron core jacketed with soft rubber.
