Patent GB-443879-A (GB)
Title: Improvements relating to the cracking of residual oils
Filed: 1935-11-20
Abstract: A process for cracking residual oil comprises cracking the oil under mild cracking conditions (800--850 DEG  F.), cracking a cycle gas-oil under severe conditions (975--1000 DEG  F.) uniting the two streams and allowing further cracking to proceed, fractionating the products into naphtha, tar, cycle oil, and liquid residues, separating the residues into a fraction containing light tar and gas oil and pitch, and then cracking the tar and gas oil fraction under temperatures lying between those applied to the residual oil and the cycle oil (900--950 DEG  F.)  Under these conditions the gas oil is cracked but the tar is not reduced to coke.  <PICT:0443879/III/1> The residual oil is cracked in a coil 1 and mixed with recycle gas oil, which has been cracked in a coil 2, in a line 10, the mixed stream passing to a soaking drum 5 where the cracking reaction is completed.  The cracked products are passed through a line 15 into a fractionating tower 7 from which light fractions and naphtha are removed through lines 21, 20 while a light oil is collected through a line 11 for recycling to the coil 2.  The tar collecting at the bottom of the tower 7 is flashed in a drum 4 from which pitchy residues are removed through a line 18 while the vapours evolved together with a fraction withdrawn through a line 19 from the tower 7 are cracked in a coil 3 and passed to a soaking drum 6.  The cracked products from this drum are fractionated in a tower 8 into light fractions and naphtha drawn off through lines 29, 30, a gas oil recycle stock which is returned through a line 12 to the coil 2, and a fraction which is withdrawn through a line 28 and mixed with the stock passing through the coil 3.  The tar residue from the bottom of the tower is removed from the system together with the residues from the drum 4 and passed to a feed storage drum 27.

Title: Improvements in fire preventing means for cinematograph projection apparatus combined with means for automatically switching on theatre lights
IPC: G03B21/18
Filed: 1929-10-24
Abstract: 336,114. Bechaz, A. Oct. 24, 1929. Kinematograph apparatus.-Electric contacts are normally held open both by the film in a projector and by a driving belt, so that breakage of either the film or the belt will cause at least one pair of contacts to be closed to actuate a main switch whereby the projecting lamp is extinguished, lights in the theatre switched on and the motor stopped. The switch 25 is held open by the driving belt 22 and the switches 12, 15 by the film 11. Closure of either of these switches energizes an electromagnet 17 which withdraws a detent 19 thus allowing the spring 32 to open switches 7, 33 in the lamp and power circuits respectively, and close a switch 8 in the theatre lighting circuit.
Patent GB-324658-A (GB)
Abstract: 324,658. Hamilton, R. M. Oct. 30, 1928. Totalizators; registering simultaneous actuations upon a single counter.-An impulse-responsive unit serving also to transmit movements due to impulses imposed on other similar units, comprises an actuator movable in one plane to drive an intermediate member that is also capable of receiving movements in another plane from the other units. As shown in Fig. 1, a magnet-winding 17 serves to reciprocate an armature 13 connected by a sleeve 46 with a thrust member 21 bearing on a boss 23. This boss constitutes the intermediate member, and is provided with arms 27 extending into slots in a block 26 fixed to the shaft 25. On the arms are pivoted spring-controlled pawls 29 adapted to engage a crown ratchet wheel 30 secured to the adjacent end of the shaft 25 belonging to the next unit. The block 26 carries pawls 32 constantly engaging the ratchet wheel to convey the rotations to the shaft 25. When the magnet is energized the sliding of the boss 23 thus produced causes a tangential thrust of the pawls 29 so that the ratchet-wheel and therefore the shaft 25 of the next unit are rotated one step irrespective of whether a rotation is being conveyed through the present unit by way of its shaft 25 and the pawls 32. In a modified construction, the armature is normally held by the magnet, and, when the circuit is broken, advances under spring pressure to drive the ratchet wheel. Instead of the retaining-pawls 32, the member 23 may carry two sets of pawls engaging opposite crowns of teeth on a double ratchetwheel 30, which is thus driven by a half-tooth at each movement to-and-fro of the member. Fig. 5 shows the electrical connections for a ticketissuing machine dealing with three horses. When a horse key 54 is depressed the corresponding impulse-receiving unit magnet 17 operates, and its armature also closes a pair of contacts 43, 44 to energize a magnet 56. A switch 58 is thereupon swung over to throw the pointing and issuing mechanism into action by means of a magnet 60 and at the same time to break the circuit through the key and magnet 17. The key and the switch 58 are restored to normal mechanically by the operation of the machine. Specifications 287,767. and (in the Provisional Specification) 307,816, 312,970, and 324,615 are referred to.

The dye may be acridine orange (3, 6-bisdimethyl-amino-acridinium-choride) in aqueous solution in a concentration between 10<SP>-7</SP> and 10<SP>-5</SP> gms per cc., and having a pH factor and an osmolality within the normal physiological ranges for human blood plasma. The pH factor may be obtained by addition of phosphates e.g. NaH 2 PO 4  and Na 2 HPO 4  and the osmolality adjusted by addition of sodium chloride e.g. to give a 0.85% solution. A method of producing a solution such as the latter is described. Instead of the phosphate buffer, HEPES (N-2-hydroxyethylpiperazine- N'-2-ethanesulfonic acid), or TRIS (2-amino- 2-(hydroxy-methyl)-1, 3-propanediol), may be used. Examples of various concentrations of acridine orange solution were given. The dye is characterised by a green fluorescence for white cells and red for granulocytic cells. Other dyes are mentioned which produce a fluorescent effect with cells:-phosphine (very mild-yellow for white cells) and (even more mild fluorescence) phenosafranine, neutral red, auromine O and acradine yellow.

Abstract: 410,787. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Spanner, H. J. ; 117, Chausseestrasse, Berlin.) Nov. 21, 1932, No. 52875. Convention date, Nov. 21, 1931. [Class 39 (i).] In lamps of the "high-pressure" type having thermionic cathodes and a filling of permanent gas and metal vapour arising from a body of metal not forming the anode or cathode but strongly heated by the discharge, to thermionic electrodes are placed so near the end walls. of the tubular envelope that the heat from the discharge and radiation from the electrode keep the end walls at substantially the same temperature as the side walls and undesirable condensation of metal behind the electrodes is thus avoided. The vapour may be mercury at not less than 100 mm., cadmium, zinc, lead or bismuth, the envelope being of quartz or refractory glass. Cadmium-amalgum lamps are also referred to. The electrodes may comprise a nickel helix 4 filled with alkaline earth oxides and mounted on a short-circuiting clip 4<1> as described in Specification 397,162 and may be heated by the discharge itself or by an external souce of energy. The ends of the envelope closely surround the electrodes as shown and the lead 5 between the seal and the electrode is very short. To promote uniformity of temperature and avoid local overheating, the thickness of the walls can be varied, for example, the wall is thinned at 1 above the electrode 4. The accidentally thinned part at the sealing-off pip 2 is covered by an asbestos cap. The amount of the vaporized metal 3 is limited to that required to produce sufficient vapour pressure, extinction of the discharge by an increase in voltage and so in temperature and vapour pressure being thus avoided. In introducing the metal during manufacture of the lamp, one small portion is cooled whilst the rest of the lamp is kept warm. All the metal then condenses on the cool portion and its amount can be estimated and compared with a standard lamp. Several metals can be successively introduced in this manner. Specification 398,799 also is referred to.
