W., Ivydene, Ellesmere Road, and PEACOCK, H., 98, Manchester Road, both in Altrincham, Cheshire. July 31, 1934, No. 22324. Addition to 393,587. [Class 100 (iii)] Distributing matrices.-In means for holding the spacer transfer-finger out of contact with the spacers during its forward stroke over them, the pivoted tumbler described in the parent Specification, for holding the transfer-finger in raised position, is dispensed with. In one arrangement, the transferchannel 1, Fig. 1, carries a pivoted rail 7, the free end of which rests on a pin 9 and has a downwardly inclined portion 7<a>. During its forward stroke, the transfer-finger 5 rides up the incline 7<a> and rests on the rail 7, falling behind the end spacer on reaching the end of the rail. In another arrangement, the finger 5, Fig. 2, is raised during the forward stroke by contact with the elevator-bar 18. The finger is held in raised position by a spring plunger 15, which engages a notch in a pin 19, pivoted to the finger and guided in its actuating-lever 6. The plunger 15 is pushed in by contact with the line transferslide 2, so as to release the pin 19 and to allow the finger 5 to fall.

Abstract: 1430098 Photo-conductive layer RANK XEROX Ltd 10 May 1973 [10 May 1972] 22415/73 Heading G2C A photo-conductive layer is prepared by curing a layer of a photo-conductive composition on a support surface, the composition comprising a dispersion of photo-conductive particles in a curable silicone rubber stock comprising a compound of Formula wherein n is an integer such that the stock has a molecular weight of several ten thousands to several hundred thousands, R 1  and R2 are alkyl or aryl groups and OR and OR<SP>1</SP> are oxime or alkoxy groups. The curing process proceeds at room temperature or slightly above by means of atmospheric moisture. The photo-conductive particles may be S, Se, ZnO, TiO 2 +ZnO, ZnS, CdS or CdCO 3 +CdS and may be mixed with Rose benzal. Fillers such as silica, titania and calcium phosphate may be added. The support may be aluminium or conductively-coated paper and may be pre-coated with a silicone resin which is allowed to cure at room temperature before application of the photoconductive layer. Alternatively a mixture of ZnO in an epoxy ester or a styrene-alkyd resin optionally containing a polyisocyanate may be applied to the support and cured prior to coating with the photoconductive composition. An intermediate solventinsoluble layer of a styrene-alkyd resin may be interposed between the two photo-conductive layers. The layer may be used to prepare a lithographic plate.

Title: Thermal treatment of gases and vapours
IPC: C07C5/327
Filed: 1933-08-11
Abstract: <PICT:0425606/IV/1> In heating gases or vapours to effect chemical reactions, the gas or vapour is passed through a heated reaction vessel in which its flow along the wall of the vessel is unobstructed, but in which its rate of flow is repeatedly varied.  As shown, the gas or vapour is passed through a tube 1 in which baffles 10, not extending to the wall of the tube, are mounted on a rod 8 held by supports 9; the tube is heated electrically to a temperature ascertained by a thermocouple 5 connected to a millivoltmeter 6. Two such tubes may be used in series, one for preheating and the other for the reaction.  Modified forms of apparatus are described in which the rod 8 is hollow and serves either to introduce the gas or vapour into the tube or for the passage of water or steam which travels in counterflow to the gas or vapour.  Tubes heated by gaseous, liquid or solid fuel may be used instead of electrically heated tubes.  The process is particularly useful in cracking gaseous or vaporized hydrocarbons, and examples are given in which (1) ethane is treated at 940 DEG  C. to yield ethylene; (2) propane is treated at 947 DEG C. to yield ethylene and propylene; (3) n-butane is treated at 915 DEG  C. to yield ethylene, propylene and butylenes; (4) a hexane mixture is treated at 952 DEG  C. to yield ethylene, propylene, butylenes and butadiene; (5) dipentene vapour diluted with carbon dioxide is treated at 740 DEG  C. to yield isoprene; (6) a mixture of cyclohexane and water vapour is treated at 770 DEG  C. to yield butadiene.ALSO:<PICT:0425606/III/1> In heating gases or vapours to effect chemical reactions, the gas or vapour is passed through a heated reaction vessel in which its flow along the wall of the vessel is unobstructed but in which its rate of flow is repeatedly varied.

Abstract: 306,194. British Thomson-Houston Co., Ltd., and Mayo, C. G. Aug. 29, 1927. Currents at distant places, measuring.-In a method of feeding a wattmeter, ammeter or other current-responsive instrument 5 in which special accuracy is required, voltage drop in the pilot conductor 4 between the instrument and the current transformer 2 is eliminated or substantially reduced by including the pilot conductor in the circuit of a second current transformer 3 feeding an auxiliary load such as an instrument or relay in which special accuracy is not required. By using transformers having the same ratio, the difference current carried by the pilot conductor may be made practically zero. A similar arrangement is used for each line of a three-phase system.

The anodes 80 are connected to individual drivers 130. The cathode 100S of the first column is connected to an individual driver 161, while the remaining cathodes are connected in groups of three to drivers 160A, 160B and 160C. The cells 50S of the first column act as particle-supply or reset cells, and turn on with the aid of keep-alive cells 123. The panel is scanned by pulses applied to the cathode drivers 160A, 160B and 160C by counter 162 to cause the columns of cells to turn on sequentially with the aid of excited particles which diffuse along the channels 120. The glow in ON cells is modulated by signal information on the anodes 80. The system may be modified to drive a two-layer panel by including a second set of anode drivers for the second set of anodes. (Fig. 11, not shown). In an alternative system (Fig. 8, not shown) channels 126 are provided for each column and a row of particle supply cells in communication with a keep-alive cell is provided at the top and at the bottom of the panel. The anodes 80 are connected to a turn-on sequencer so that propagation of excited particles and the turn-on of cells in each column takes place vertically from the top and bottom of a column to the centre. The channels 120 are still provided but are not required in this system of operation.
