Title: Process for the recovery of sulphur
IPC: C01B17/04
Filed: 1934-06-12
Abstract: Sulphur is recovered from the gases evolved during the smelting of pyrites by bringing the gases while still hot into contact with an equivalent amount of a gaseous, liquid or powdered solid reducing agent and passing the resultant gases and vapours through a catalytic chamber filled with brick or other contact material coated with sodium carbonate or other alkali metal compound mixed or not with an iron compound, e.g. English Red.  Alternatively the alkali compound may be introduced into the shaft of the smelting furnace.  The admixture with reducing agent may take place in or away from the furnace.  Solid impurities may be removed from the gases, e.g. by a Cottrell apparatus, and the condensation of the sulphur may be similarly effected.  The Specification as open to inspection under Sect. 91 comprises also the use of iron or an iron compound as the catalyst, and any electrostatic process may be used to remove solid impurities and to condense the sulphur.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,144,577. Photo-electric position finding systems. SOC. ANON. DE TELECOMMUNICATIONS. 21 April, 1966 [22 April, 1965], No. 17408/66. Heading H4D. In a guidance system for aircraft fixed lines of infra-red radiation discontinuity relative to the surrounding medium are provided and on the craft an infra-red detecting device scans repetitively the area including such fixed lines in a plane normal to the longitudinal axis of the craft, the electric pulses ensuing at the output of the photo-cell of the detecting device are applied to one deflexion circuit of a cathoderay tube (C.R.T.) and another deflexion circuit of the C.R.T. affords a sweep in synchronism with the scanning by the detecting device. The invention is particularly described as applied to an aircraft approaching a runway. The fixed lines may be on or below the ground and may consist of wires heated by electric current, of tubes through which a heating or cooling fluid flows, or polished metallic surfaces. The positions of the pulses on the C.R.T. indicate (for a fixed flight aspect) the extent to which the aircraft is off a centre-line defined by the fixed lines and its height. The height may be computed utilizing a bi-stable multivibrator, to which the camera output pulses are supplied, and an integrator; the measurement is displayed on a dial instrument or as a spotdisplacement on the C.R.T. Camera scanning is by a rotating mirror; C.R.T. sweep synchronization is by photo-electric or magnetic " reading " of an indexed disc coupled to the driving motor of the mirror.

Title: Improvements in the selective protection of electric distributing networks having aninsulated neutral point
IPC: H02H1/00
Filed: 1930-06-06
Abstract: 358,541. Protective cut-out arrangements. JONNART, A., 74, Rue de l'EgalitÚ, Charleroi, Belgium. June 6, 1930, No. 17597. Convention date, June 14, 1929. [Class 38 (v).] Selective protective arrangements for distribution networks, particularly those with an insulated neutral, comprise directional relays and earth relays the actions of which are controlled by combinations of further relays, such as monophase wattmeter relays adapted to deflect in either direction, individually connected to the phases. A pair of feeders I, II is provided at each end with a circulating-current system G, across normally equipotential points of which are connected the current coils of a wattmeter-type directional relay D, the current coils being associated with coils energized by the respective voltages in quadrature at unity power-factor. An earth relay E has its current coil in series with those of relay D and its voltage coil energized by the neutral-to-earth voltage. Oppositely-acting wattmeter relays R‹ .. T‹ are energized by the neutral-to-earth voltage and also by the interphase voltage and actuate contacts in series with a solenoid R<ooo> arranged to pick up only when two-thirds of its winding is energized. In the event of a fault to earth on two lines, two relays, say R‹, S‹, deflect to the left and T‹ to the right, whereby the coil R‹‹‹ acts to close contacts A‹ and put the relay E out of action by shorting its current coil. If a single earth fault occurs, only one-third of coil R‹‹‹ is energized, and the earth relay E can operate. To prevent the relay D from operating also, further contacts could be provided for the solenoid R<000> such that relay D was cut out when relay E was in circuit. This system can be modified by providing further contacts on solenoid R<000>operating an indicator where the first section of a line has a single earth fault and the earth relay E would not operate as the sum of currents would still be zero. Instead of the relays D, E there could be used relays responsive, respectively, to the inverse power and residual power, the relays R‹ .. T‹ being then energized by the phase, instead of interphase, voltages. Further modifications are described to meet the condition of a simple earth on the first section with only a single line, or when one of a pair of parallel lines was out of service, such modifications involving additional relays energized by (current)<2> or (voltage)2. Arrangements are also described to meet cases where a double earth occurs on the first section and a single earth on the next section.

Title: Improvements in material reduction mills and the operation thereof
IPC: B02C17/04
Filed: 1951-07-25
Abstract: 696,166. Grinding mills. WESTON, D. July 25, 1951 [June 22, 1951], No. 17663/51. Class 59  In the operation of a rotary grinding drum 10 of the kind'in which the drum is charged through a feed port 11 and the product is withdrawn through an outlet port 12 by a current of air drawn through the feed and outlet ports by means on the outlet side of the drum, the air pressure within the drum is subjected to periodic sudden reductions followed by returns to normal conditions. The drum is charged by a conveyer 14 leading to a feed shoot 15, and an outlet duct 16 connected to the port 12 leads to the inlet of an impeller 22. When the air circulation is of the opencircuit type, as shown in Fig. 1, air is delivered through the mouth 26 of the shoot 15 and the impeller discharges to atmosphere; when the air circulation is of the closed-circuit type as shown in Fig. 2, the impeller discharges through a conduit 28 leading to the feed shoot. The means for controlling air pressure in the drum may consist of a valve 27, Fig. 1, disposed across the mouth 26 of the shoot 15, or a valve 37, Fig. 2, so disposed in the duct 16 that when the valve is open the duct is in communication with atmosphere, or a valve 38, Fig. 2, disposed at any, position in the return duct 28 and preferably at its connection with the shoot 15; to prevent the build-up of back pressure when the valve 38 is suddenly closed, a bypass 39 is fitted with a safety valve 40 and may be enclosed in a dust bag. A preferred form for the valves comprises three rubber diaphragms 52, 53, 54, Fig. 9, mounted on axles 57b and operable to open and closed positions by a solenoid 70 which actuates a chain passing over sprocket-wheels on the axles. The solenoid may be actuated by one timeoperated relay to open the diaphragms and a second such relay, which is energized upon actuation of the first relay, to close them after a predetermined time; in the case of the valve 37, for example, it may be opened for a period of one second at ten-second intervals. If desired, the control may be exercised in the closed circuit by both valves 37, 38, Fig. 2, operated in timed sequence, or, in the open circuit, the valve 27, Fig. 1, may be used in timed relation with a valve positioned similarly to the valve 37, Fig. 2. In all cases, the air current is maintained at least in part throughout the cycle, this being provided for in the case of the valve 27 by arranging for it never to be completely closed and in the case of the valve 38 by the air leakage at the entry of the conveyer 14 to the shoot 15. If desired, the drum may be used with a ball charge as described in Specification 696,164, which together with Specifications 632,532 and 695,137 is referred to.
