Title: Improvements in and relating to pneumatic tube conveyor systems
IPC: B65G51/28
Filed: 1946-02-11
Abstract: 607,742. Pneumatic despatch apparatus. LAMSON ENGINEERING CO., Ltd., and BURL, J. Feb. 11, 1946, No. 4207. [Class 78 (i)] A despatch terminal comprises a housing 1 having an opening 2 into which the transmission tube 3 is fitted, an opening 4 opposite thereto for the introduction of a carrier, an opening 7 to atmosphere in a plane substantially at right angles to that of the opening 4, an opening 9 for the attachment of a control device 10 of known kind, and a lever 11 pivoted at 12 inside the housing and carrying at one end a disc 6 adapted to control the opening 4 and at the other end a disc 8 adapted to control the opening to atmosphere so that both discs are operated simultaneously when a carrier is inserted into the opening 4. The area of the opening 7 is considerably greater than the area of the opening 4 so that when the disc 8 closes the opening 7, the pressure is sufficient to hold the disc 6 in the closed position against the suction of the system. A buffer 16 is provided on the face of the disc 6.

Title: Improved fault detection means in servo control systems
Inventor: FLINDT CHARLES BARRY
IPC: G05D1/00
Filed: 1957-02-07
Abstract: 853,674. Controlling aircraft. SHORT BROS. & HARLAND Ltd. Jan. 21, 1958 [Feb. 7, 1957 ; Sept. 13, 1957], Nos. 4234/57 and 28906/57. Class 4. An electric control system on aircraft between an input control member and an output controlled member such as a control surface comprises three transmission channels supplied with input signals responsive to the movement of the input member, means for sampling the signal in each channel, and for comparing each sample with each of the other two, and warning means responsive to any disparity between the samples to indicate the identity of a defective channel. A control column 10 is connected to the pick-off arms of three ganged rheostats 11, 21 and 31 each energised from a common source, not shown, to provide identical input signals to three channels I, II and III, the input signals being amplified at 13, 23 and 33 to energise output members 15, 25 and 35 which each comprise a transducer driving the spindle of a valve in a hydraulic servo mechanism which operates control surface 50. Feedback circuits 16-17, 26-27 and 36-37 are provided to the respective amplifiers and a fault detector 14 is arranged to sample the amplifier output in each of the three channels and is connected at 54 to indicators respectively associated with each channel. The detector 14 comprises three similar relays A, B and C each comprising a pair of opposed coils 41, 42, an armature 44 pivotally mounted between the coils ; a warning switch 51 and a supply switch 52, the movable contacts of these switches being respectively attached to the ends of the armature. The movable contact of each warning switch 51 is connected to the fixed contacts of the supply switch of one of the other relays and the movable contact of each supply switch 52 is connected through lead 53 to a source of power, conveniently tapped from the channel which is not sampled by the relay. The fixed contacts of each warning switch 51 are connected to one of three warning circuits 54 connected to a warning lamp (not shown). Each channel is sampled two coils of different relays e.g. channel I is sampled by coil 41 in relay A and coil 52 in relay C, channel II by coil 42 in relay A and coil 41 in relay B, and channel III by the coil 42 in relay B and coil 41 in relay C. If a fault develops, for instance in channel I the disparity in the signals sampled from this channel actuates relays A and C and closes the switches in these relays. The warning switch 51 in relay A and supply switch 52 in relay C being closed, and interconnected, the warning circuit associated with channel 1 is energised. The warning circuit for channel III is not energised for it derives its power source from dejective channel I. A further embodiment is described incorporating additional feed-back circuits. It is stated in the first Provisional Specification that means may be provided for " holding " an indicator in warning condition and/or for automatically isolating a faulty channel.

Title: Improvements in or relating to the catalytic synthesis of hydrocarbons
IPC: B01J23/94
Filed: 1947-02-14
Abstract: <PICT:0626742/III/1> Hydrocarbons and oxygenated products are prepared by forcing carbon monoxide and hydrogen into a reaction zone containing a fluidized iron catalyst which is withdrawn continuously or intermittently, quenched, heated to at least incipient fusion in an oxidizing gas to agglomerate the particles and remove carbonacous contaminants, ground to the desired size, and returned to the reactor.  In a delayed settler, bottom draw-off reactor, the bulk of the catalyst has a particle size of 40-200m , with less than 20 per cent of 0-20m .  With an increase in fines through disintegration, coarse catalyst, for example 80-200m . is added.  Used catalyst may be withdrawn by pipe 4, quenched to atmospheric temperature in water 6 or other liquid, e.g. alcohol, to which wetting agents or catalyst promoters may be added, withdrawn by conveyer 8, drained to about 21 per cent water content on 10, and discharged to mixer 12 where fuel is added if necessary.  Coarse iron oxide, either unused or resintered from hopper 15, equivalent to 10-60 per cent of the catalyst to be resintered, is fed to a grate bar conveyer having a screen 14, the mixture from 12 forming an upper layer.

The joints may be supplemented with a jointing solution or covered with a jointing strip and again press cured, or may be made with air curing solution and not press cured. The textile material may consist of two rubbercoated plies laid face to face. The surface of a single ply which is to form the inner surface of the hose may be covered with rubber, for example by being friction or spreader coated with rubber and then faced with a rubber sheet or layer. In one method of forming the joint, Fig. 1, two plies after being coated are superposed in staggered arrangement to leave overlapping edges C, D and then press cured. The edges are brought together as shown in Fig. 1, with the edges A, B abutting and the edges C, D overlapping them, and the seam or joint consolidated by pressure and heat. Thin layers of rubber E, F may be interposed between the laps. Figs. 2 and 3 show alternative forms of joint.
