Title: Display system
IPC: G09F13/00
Filed: 1961-04-07
Abstract: 954,999. Colour projection systems. STANDARD TELEPHONES & CABLES Ltd. April 7, 1961 [April 12, 1960], No.12625/61. Heading G2J. [Also in Division G4] Apparatus for visually displaying in colours on a screen information represented by symbols on two display areas of a medium (for example a film) comprises a white light source for projecting one display area and a coloured light source for projecting the other display area so that the two projections overlap and to the viewer there appears a coloured display including a colour other than that projected by the coloured light source. As shown in Fig. 1, information from a source 7, such as a computer, is fed to a character writing cathode ray tube 6 so as to expose a light sensitive film 4 which is processed to a negative at 10. Subsequently, a desired frame of the negative is positioned in front of a housing 2 containing a white light source 2c so that the area 4b of this frame, Fig. 3, receives white light from the lamp 2c whereas the area 4c receives coloured light from afilter 2d. These areas 4b, 4c contain opaque symbols on a transparent ground so that some areas on a display screen 1 will receive only the coloured light while other areas will receive a mixture of the coloured with the white light. Thus, each of the alphabetical characters, for instance, will appear as red letters on a soft-white background and all the symbols will be shown on screen 1 as a multicoloured display. The colour of the light which is received by the frame area 4c may be varied by providing, instead of a single filter 2d, a rotary member which carries several colour filters and the different colours may be made indicative of certain information. For instance, while the different symbols may be representative of altitude, range, speed, and position of an aircraft, red coloured light may signify a civil aircraft and a green coloured light military aircraft. In a second embodiment, Fig. 4, the light beams emerging from a lamp housing 20 are duplicated so that there are two white light beams 20b, 21b and two coloured light beams 20a, 21a, produced by filtering white light at 20d and 21d. Also provided on the housing 20 are two masks 20c and 21c which are formed by rotatable discs having opaque and transparent quadrants and so arranged that either the white and coloured light beams 20b and 20a or the white and coloured light beams 21b and 21a are operative. In this way, it is ensured that only one of the two frames 40a, 40b and 41a, 41b is displayed on the screen 1 at any single time. Frames 40a, 40b may carry information relating to the speed, position &c. of an aircraft over a particular territory while the frame 41a, 41b may relate later information about the same aircraft.

Abstract: 474,526. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., and SCOTT, W. J. May 5, 1936, No. 12696. [Class 39 (i)] [Also in Group XI] In an extra-high pressure lamp in which fluorescent material in proximity to the envelope is carried by means other than a reflector for the lamp and constitutes a light transmitting screen, the material is cooled by the cooling liquid for the lamp which flows rapidly over the surface of the lamp at a pressure higher than atmospheric. The material may be on the outer surface of the lamp itself or upon screens within the cooling jacket; alternatively, the fluorescent powder may be suspended in the cooling liquid, which has, in this case; a closed circulation. By using suspensions of powders having long afterglow, the apparent shape of the light source may be altered. The high pressure in the cooling sysem enables the thickness of the quartz walls to be reduced. Specifications 154,199, [Class 39 (i)], 403,208; and 443,549, [Group XI], are referred to. The Provisional Specification refers to cooling liquid pressures of 50-100 atmospheres or more.

Title: Method of and apparatus for evaluating lost circulation materials of drilling mud
IPC: E21B21/00
Filed: 1963-04-01
Abstract: 1,059,311. Boring earth &c. BRITISH PETROLEUM CO. Ltd., E. H. N. WATSON and G. H. SMITH. March 11, 1964 [April 1, 1963], No. 12784/63. Heading E1F. The suitability of materials for sealing fractures or fissures in a formation being drilled is evaluated in a cell comprising a body 11 having a wedge-shaped slot 19, the aperture of and the slope through the slot being adjustable to permit simulation of different sized fractures and fissures. One wall of the slot is formed by a bar 15 the ends of which may be moved inwardly by screws 9 and outwardly, following slackening of the screws, by springs 18.The suitability of material contained in drilling mud for plugging fractured formations is found by first removing caps 26, 41 and passing the mixture through the slot until, if the material is effective, a plug is formed. The reservoir 13 is topped up with the mixture, the cap 26 replaced and gas pressure applied through a port 29 in the cap 26. If after some time the plug is still effective a higher gas pressure is applied for a further period, and if the plug is still effective a higher hydraulic pressure is applied, the cap 41 being replaced. If the plug withstands this pressure, the pressure is removed and gas pressure is applied through a port 24 to compress the plug for a time after which the hydraulic pressure is reapplied. If the plug does not fail the material is suitable for sealing fractures of similar dimensions to those of the slot.

Title: 18-o-acyl-17-hydroxy-yohimbane derivatives
IPC: C07D459/00
Filed: 1964-03-26
Abstract: The invention comprises: (a) lactones of formula <FORM:1000528/C2/1> where R represents a hydrogen atom or a methoxy radical and Y is a tetrahydropyran or tetrahydrofuran group, and (b) a process for the preparation of yohimbane derivatives of formula <FORM:1000528/C2/2> in which Ac is the residue of an organic carboxylic or sulphonic acid, R is a hydrogen atom or methoxy radical and R1 is a C1-C3 alkyl radical, wherein an acid of Formula I where R1 and Ac represent H is either reacted with dicyclohexyl carbodiimide or is heated with acetic acid acetic anhydride and the intermediate 17-O-acetyl compound subsequently carefully saponified with a weak organic or inorganic base, or the corresponding 3-epi acid is heated with acetic acid-acetic anhydride, epimerization at the C3 atom occurring at the same time, and the intermediate 17-O-acetyl compound subsequently carefully saponified with a weak organic or inorganic base, to give the 17-hydroxy-g -lactone, the 17-hydroxyl group of which is then protected by acetal formation and the products transformed by alcoholysis with an alkali metal alcoholate in the corresponding C1-C3 alcohol into an 18-hydroxy ester, the latter converted to the appropriate acyl compound by esterification, and the acetal group split off by acid hydrolysis. Suitable weak inorganic and organic bases for the saponification of the 17-O-acetyl compound obtained as intermediate are alkali metal bicarbonates and triethylamine.  The protection of the hydroxyl group of the -lactone by an acetal group preferably takes place by reaction with dihydrofuran or dihydropyran with the addition of an acid such as p-toluene sulphonic acid or anhydrous hydrochloric acid, in an inert solvent, e.g. dimethylformamide.  The esterification of the 18-hydroxy ester may be performed by reaction with acid anhydrides in pyridine or by use of acid imidazolides.  The acids used as starting materials can be obtained by alkaline saponification of methyl pseudoreserpate or 3-epi-methyl pseudoreserpate obtainable from reserpine, rescinnamine or deserpidine. The reaction mixture obtained in the production of these acids may be used directly for the process according to the invention. Specifications 915,779 and 937,598 are referred to.

Title: Improvements in or relating to electronic frequency converting apparatus, particularly for resistance welding
IPC: H02M5/00
Filed: 1950-05-26
Abstract: 673,510. Frequency changing. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 26, 1950 [July 1, 1949], No. 13266/50. Class 38 (ii). In a frequency conversion system for electric resistance welding and comprising a plurality of electric discharge devices, e.g. ignitrons, fired in succession as is described in Specification 657,810, the system includes an electronic control device which causes late firing of the first ignitron immediately after firing of the last ignitron at the end of half-cycle of the output frequency so as to accelerate delay of the current flow maintained by the last firing ignitron and thereby avoid simultaneous conduction and overlap by the last ignitron of one half-wave output with the first ignitron of the opposite half-wave and so prevent a shortcircuit on the supply mains. In the arrangement described which comprises two groups each of three ignitrons 1TU, 3TU, 5TU and 2TU, 4TU, 6TU connected in inverse parallel relationship with the three phase supply mains L1, L2, L3, which groups provide respectively the half-waves of the single-phase output current to the transformer T, the ignitrons of one group are fired in succession upon application of a single pulse over lines 66 (or 80) to the control valve 1CT (or 2CT) of the first ignitron, the control circuit 107 (or 108) for the additional late firing of the first ignitron in either group comprises a valve 7CT (8CT) whose grid circuit is coupled with the output circuit of the control valve 5CT (6CT) for the last ignitron of the group so as to render conductive valve 7CT upon control valve 5CT conducting and thereby cause control-valve ICT to re-conduct through the coupling 117 between the output circuit of valve 7CT and the grid circuit of firing valve 1FT. The invention is applicable to systems in which the load requires pulsating current only and in which the supply mains are singlephase.
