IPC: G01S3/787
Filed: 1964-02-06
Abstract: In the kind of photo-electric position finder having a reticle chopping the received radiation before it reaches the photo-cell, a known reticle pattern (Fig. 6, not shown) comprising zones 10, 11 is modified by the inclusion of a transition region 16 having an axis 9 oblique to the direction of pattern motion and incorporating alternate radiation-transparent and opaque strips those of which adjoin zone 10 having a width measured in the direction of motion equal to the width of " gaps " and " spokes " in zone 10 and those of which adjoin zone 11 having a width measured in the direction of motion equal to the width of gaps and spokes in zone 11. The reticle may be a disc or a loop. The pattern of the invention permits the instant of pulse-frequency change, from which the co-ordinates of the object are derived, to be determined more accurately.

Transverse exhaust apertures 10 are formed between the walls 10a, 10b and lead through apertures 12 into ducts 11 connected through apertures 13 to a discharge chamber 14. Each exhaust aperture is separated from an adjacent one by a pair of openings 5, 5a. Each hollow member 16 is formed with a duct 17 which may be connected by pipes 18 to a source of water, air or steam by which the surface of the support bed can be heated or cooled. In a modification, Fig. 5 (not shown), the support bed is formed as a single casting. The support bed may be inclined and may be curved to support a curved sheet or ribbon of glass. Alternatively, the bed may be flat at the starting end and become curved in the direction of travel for shaping a curved sheet or ribbon. The gas cushion may be produced with different gases at any desired temperature and successive parts of the cushion may be fed with gas at graduated temperatures. A further cushion apparatus may be provided above the sheet or ribbon so as to apply treatment simultaneously to both sides.

Title: Starter circuits for discharge lamps
IPC: H05B41/04
Filed: 1968-06-10
Abstract: A control system for a discharge lamp, such as a high pressure sodium or mercury vapour lamp, comprises means whereby the restarting of a hot lamp is enhanced. A discharge lamp 12 is connected to an A.C. supply OP by way of an inductor having a tapping 11, the lamp being shunted by a circuit connected to the tapping 11 and comprising a thyristor 18 and a condenser 16. The control electrode 20 of the thyristor is connected to a point in a circuit connected across the major part 10 of the inductor, the circuit including a resistor 22 and a contact 28 operated by a relay winding 26 which is energized by the minor part 13 of the inductor by way of a full-wave rectifier 24. When the system is initially switched on by a switch 14 the inductor carries little current, the relay winding 26 is thus not energized and the contact 28 remains open. A periodic signal is thus devised by way of the resistor 22 and applied to the control electrode 20 so making the thyristor conductive during alternate half-cycles of the supply OP. A pulsating current flows via the part 13 of the inductor to charge the capacitor 16. A high voltage is then induced across the whole inductor which causes the lamp 12 to ignite after one or, at the most, a few half-cycles of the supply. After the lamp has ignited the portion 13 of the inductor provides a voltage sufficient to energize the relay winding 26 to close the contact 28. The thyristor is thus rendered non-conductive during normal running of the lamp 12. Should the lamp be switched on when hot following a short interruption in the running thereof, the thyristor will continue to provide starting pulses for the lamp until it has cooled sufficiently to enable it to be re-ignited.

Title: System for the introduction of powdery material into an enclosure containing a gas
IPC: B01J8/00
Filed: 1969-02-03
Abstract: A system for feeding powdery materials into an ascending current of hot gases in a conduit 1 connecting two cyclones of a cement-works preheater consists of a supply duct 2 leading to a vertical tube 4 which is provided at its bottom end with a valve member 7 connected by a rod 8 to a counter balanced control system 10, Fig. 2 (not shown). In operation, when the tube 4 is empty, the counterweight closes the valve 7. When the duct 2 is supplied with powdery material, the material accumulates in the tube 4 until the weight of material overcomes the action of the counterweight, causing the valve to open and allowing a thin conical sheet of material to pour into the conduit 1 to be entrained by the rising gases. The control system 10 includes adjustable stops whereby the movement of the valve 7 is limited. The tube 4 is slidable within a sleeve 3 mounted on the end of the duct 2.

Title: Adsorption process
IPC: B01D53/047
Filed: 1969-05-06
Abstract: In a pressure swing adsorption process for continuously separating feed gas mixture using at least three adsorbent beds by the repeating cycle, steps of sequentially contacting the feed gas mixture with each bed in turn at a first, higher, pressure for selective adsorption of at least one component and discharge of one-component-depleted product gas, desorbing the bed by depressurization to a second, lower, pressure and at least partially repressurizing the desorbed bed by the product gas preparatory to recontacting the bed with the feed gas mixture, the flow rate of the repressurization gas is controlled in linear dependence on the relative adsorption rate so that the repressurization of each bed in turn can be spread uniformly over the adsorption period of the bed then in contact with the feed gas mixture, thereby avoiding rapid pressure fluctuations. Indications of relative adsorption rate may be obtained by measuring the flow rate, temperature, or pressure of the feed gas mixture, or the flow rate of the product gas, or detecting the arrival of the adsorption front at a particular point in the bed. The difference between the repressurization pressure and the feed gas pressure may be measured and the repressurization flow control valve may be automatically adjusted so as to tend to make simultaneous detection of the adsorption front and reduction of the difference between the repressurization pressure and the feed gas pressure to a given limit. The adsorbent material may be a crystalline zeolitic molecular seive, activated carbon, or silica gel. Three bed and four bed processes are described in detail (Figs. 4 to 7, not shown).

A cylindrical shroud peripherally encloses both legs of the tube bundle and the preheater's outlet discharges upwardly into this cylindrical shroud, the latter forming an annular feed-water descent space between it and the generator's housing and its lower end opening to the tube sheet for feed water flow thereover and ascent upwardly through the shroud. A steam-water separator is positioned in the housing above the shroud and has an inlet for receiving a steam-water mixture from the latter, and a steam outlet connecting with the housing's steam output outlet and a separated feed-water outlet connecting with the descent space. An enclosure encloses substantially the full length of the bundle's inlet or hot leg and is connected at its upper end with the separator's steam outlet and at its lower end with the housing's steam output outlet whereby to interconnect these outlets, the steam from the separator being superheated while flowing along the bundle's inlet leg. A second enclosure encloses the length of the tube bundle's outlet or cold leg and connects at its lower portion with the preheated feed-water outlet of the preheater and at its upper end with the steam-water mixture inlet of the water separator. Means are provided for force pumping into the preheater's feed-water inlet, a certain flow of feed-water from the descent space and which mixes with the feed-water fed to the preheater from the outside of the housing.
