Title: Circuit arrangement for supervising a plurality of signal circuits with respect to interruptions
IPC: G08G1/097
Filed: 1964-03-12
Abstract: 1,045,629. Transistor switching circuits. STANDARD TELEPHONES & CABLES Ltd. March 12, 1964 [March 14, 1963], No. 10468/64. Heading H3T. [Also in Division G4] An alarm circuit for monitoring a number of signalling devices, e.g. traffic lights H, connected to a common point E comprises a relay B which is normally held energized by the current following through its winding 1, 2 and the emitter collector path of transistors T1, T2. An A.C. supply is connected between P and N and during the half cycle when P is negative relay B is held in by the decay current flowing through diode G1. If a lamp H fails during the time that its associated switch s is closed, the potential at E tends towards that of P during the half cycle when P is positive, and the transistors are cut off releasing relay B to complete an alarm circuit. Any tendency for residual current to hold the relay in is counteracted by a small opposing winding 3, 4. Excessive voltage drop across the transistors when blocked is prevented by Zener diode G2. A further Zener diode prevents damage to the transistors should one of the diodes G1 or G3 fail. In the case of the latter failing a fuse Si is also tripped. If, however, one of the transistors should go short-circuit, the system will still function with the remaining one. A switch T p  is provided for testing the system. Transistor T2 and winding 3, 4 may be omitted, Fig. 1 (not shown).

Title: Process for the destructive hydrogenation of normally liquid or fusible carbonaceousmaterials
IPC: C10G1/06
Filed: 1937-04-15
Abstract: In the production of valuable hydrocarbons by subjecting liquid or fusible carbonaceous materials, e.g. olefinic oils poor in hydrogen and containing as impurities oxygen and nitrogen, to a refining hydrogenation followed by a destructive hydrogenation, both the hydrogenations are carried out in presence of catalysts supported on carriers consisting of substances comprising carbon, silicon and aluminium or their compounds.  The carriers are preferably pretreated to activate them, e.g. by treatment with hydrogen or steam or with acids, e.g. hydrofluoric acid.  Carriers specified include active carbon, active silica, bauxite, brown coal, small coke, clay shreds, bleaching earths &c. preferably pretreated to remove ash and basic constituents, or treated with fluorine or its compounds, or subjected to a swelling treatment. Catalysts for mounting on the carriers comprise metals and their compounds of Groups 5-8 of the periodic system particularly sulphides, e.g. tungsten sulphide.  The catalyst may be used in amounts up to 20 per cent by weight of the carrier. The catalyst and carriers may be mounted stationarily in the reaction vessel or dispersed in the material to be treated.  Conditions for the refining stage comprise temperatures from 300-480 DEG  C. and pressures of 50-500 atmos. while the temperatures used in the second stage may be higher or lower.  A mixture of brown-coal tar middle oil, benzine and a coal-tar residue from the sump phase of a destructive hydrogenation of brown coal is treated at 408 DEG  C. and 250 atmos. with a throughput of 1,2 kg. of initial material per litre catalyst space per hour in presence of a stationary catalyst comprising 90 parts Terrana bleaching earth treated with hydrofluoric acid and 10 parts tungsten sulphide.  38 per cent benzine is separated from the products which are then destructively hydrogenated in a second apparatus at 380 DEG  C., and 250 atmos. pressure with a throughput of 1,5 kg. per litre catalyst space per hour in the presence of the same catalyst combination.  By mixing the benzines obtained in both stages a product is obtained containing 38 per cent of constituents boiling up to 100 DEG  C. and having an octane number of 65,5.

Filed: 1921-04-19
Abstract: 163,291. Martiny, G. von, and Horvath, L. May 8, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches, q u i c k - action; contacts.-Relates to snap-action switches of the type in which a buckled spring blade or plate is first moved to an unstable position and then springs over into a position of reversed curvature. In the form shown in Figs. 1 and 2, the bowed elastic plate c has shoes d supported in recesses c of the two-part lensshaped casing a, b, its length being greater than the distance between its supporting axes. A screw h passes through the centre of the spring plate c, securing to it push buttons f, g and a contact plate i. Depression of either push button moves the plate c first to an unstable middle position, Fig. 6, from which the spring snaps over to its opposite position. In the switch-opening operation, the stationary contact springs k are in contact with the plate i until the intermediate unstable position is reached, effecting simultaneously the snap-action and circuit breaking operations. Figs. 7 and 8 show a further modification, the spring blade c being mounted between the angles r<1> of a spring r, its lower curve resting against an outer push button t mounted in the lower casing member n, and its upper ends abutting in a recess o<1> of the upper casing member a. At the centre of the spring plate c is secured a contact plate p and an inner push-button s reciprocating within the outer push-button t. Pressure of the push-button t with the switch closed, Fig. 7, causes the angles r' to move apart, and interaction between the springs r and s brings the latter to its intermediate position, from which it snaps over, thereby opening the switch, in which position the inner push button s projects through the outer push button l. Pressure on the push button s snaps the switch back to its closed position. This switch may be modified by making only one of the angles r' movable, and the place c may consist of a thin elastic diaphragm or a bundle of elastic metal wires.

Abstract: 565,267. Electromagnetic switches ; mercury switches. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd.. and RIDDLE, H. J. N. July 16, 1943, Nos, 11630 and 21407. [Class 38 (v)] In a frequency responsive relay wherein energization of an electromagnet by impulses of suitable frequency causes oscillation of mercury or other liquid having the same natural frequency of oscillation, the mercury is contained in three vertical limbs of a vessel 3, and the electromagnet imparts movement to the outer columns of mercury to cause the centre column to close a circuit at the electrode 6. In the form shown, steel balls 11 float on the two outer columns and are attracted upwards periodically by the poles of the electromagnet (not shown) which are arranged before and behind the vessel 3 and slightly above the balls 11. When the electromagnet is de-energized, the balls fall on the mercury assisted by the pull of an adjustable permanent magnet 13 and set the mercury oscillating. In a modification, Figs. 1, 2 (not shown), there is no permanent magnet and the electromagnet attracts the balls downwards. In another modification, Figs. 6-8 (not shown), one electromagnet controls three devices each having a different natural frequency. In yet other modifications, the mercury in the centre column engages a mercury contact. Also, instead of the electromagnet acting on steel balls, it may oscillate a piston or paddle or diaphragms. The intermittent engagement of the contact 6 of the relay may cause the permanent closing of another relay circuit, for example, by giving a positive bias to the grid of a thermionic valve, the anode circuit of which controls the other relay. A condenser between the grid and cathode maintains the grid positive between successive pulses.
