Title: New Cyclic Ketones
IPC: C07D307/91
Filed: 1967-07-21
Abstract: 1,189,514. Ketones. SANDOZ Ltd. 21 July, 1967 [22 July, 1966], No. 33740/67. Heading C2C. [Also in Division C3] The invention comprises novel ketones of the general formula wherein R 1  is C1, Br, CN, R 3 , -OR 3 , -O-aryl, -CO-OR 3 , -O-COR 3 , -CO-alkyl, w-halogenoalkyl-CO-, -CO-aralkyl, -CO- cycloalkyl, -SO 3 H, or an optionally substituted carboxylic acid amide or sulphonic acid amide radical, R 2  is a carbocyclic or heterocyclic aromatic radical which may contain one or more substituents selected from Cl, Br, alkyl, cycloalkyl, -OR 3 , -COO-R 3  and -CO-N(R 3 )R 4 , X is -O-, -S-, -N(R 3 )-, -C(R 3 )(R 4 )-, -CH=CN- or -C(OR 3 ) = C(OR 4 )-, R 3  is H, alkyl, alkenyl, aralkyl, or cycloalkyl, R 4  is H, alkyl, aralkyl or cycloalkyl and each of n or m is 1 or 2, wherein at least one -OR 3  radical must be present. The compounds of Formula I, except wherein R 3  is alkenyl and R 1  is -SO 3 H or w-halogenoalkyl-CO- are prepared by reacting a compound of the general formula wherein R 5 =R 1  and -COOR 4 , -O-CO-R 4  but not -COOR 3  or -O-CO-R 3 , with a compound of the formula V-R 2 , wherein U and V represent H and a -CO- halogen radical or vice versa, and at least one of the starting materials contains an -OR 3  radical. The reaction is performed by Friedel-Crafts method, preferably using AlCl 3 . Examples include the preparation of hydroxy benzoyldibenzofurans, -carbazoles, -fluorenes and -phenanthreries e.g. dibenzofuran is reacted with 2-methoxybenzoyl chloride to yield 3- (21-hydroxybenzoyl)-dibenzofuran. Ketones having increased solubility in organic solvents are obtained by introducing halogen atoms into the molecule as in Example 39 where 3 - (2<SP>1 </SP>- hydroxy - 3<SP>1 </SP>- methylbenzoyl) - 9 - ethylcarbazole is treated with SO 2 Cl 2  to givethe 6-chloroderivative. The methoxy-, methyl- and chloro-substituted benzoic acid halides, used in the preparation, especially the acid chlorides are obtained from the corresponding carboxylic acids e.g. with SOCl 2  or a phosphorus chloride.

Title: Improvements in phototypesetting machines
IPC: B41B21/16
Filed: 1958-10-22
Abstract: 895,283. Phototypesetting machines; lens mountings. HARRIS - INTERTYPE CORPORATION. Oct. 22, 1958 [Oct. 23, 1957], No. 33797/58. Classes 97(1) and 98(1). A phototypesetting machine has a pair of lenses 20, 22 movable along the optical axis between the character matrix and the photosensitive record material, which are a fixed distance apart; the lenses can be adjusted to give a predetermined magnification of the character image on the record material, and a series of co-ordinated stops are provided for controlling the positioning of the lenses to produce a number of different magnifications. In the arrangement shown, light from a flash source 12 passes through the matrix disc 10 bearing the characters on to a film strip 16. Between them is the system of lenses 20, 22, mounted respectively on spring-biased carriers 25, 45, which slide on respective track members 28, 48. At one end of carrier 25 projects a stop 30. The action of spring 32 urges this stop against one of a series of stop pins 38a . . 38h arranged on spirally-disposed steps on a cylinder 35. Thus as cylinder 35 is turned, the lens 20 retracts step by step in a series of predetermined positions. Lens 22 can occupy a similar series of positions, determined by a similarly stepped cylinder 55. Cylinders 35 and 55 are connected together by a chain 60 passing over sprockets 40 and 57, so that by turning a crank 58, both cylinders are rotated simultaneously, giving a series of co-ordinated positions for the two lenses which provide one of a predetermined series of magnification values. The carrier 45 is initially moved out of contact with cylinder 55 by a chain 65 operated by a motor 72. During its traverse, lens holder 22<SP>1</SP> engages against the other lens holder 20<SP>1</SP> and moves it away from cylinder 35. While the lenses are drawn forwards, the cylinders 55, 35 are set to a predetermined value, and the lenses then released; under the action of springs 52, 32 they retract into the predetermined positions set by cylinders 55, 35, so giving the particular magnification required. Specifications 768,374 and 891,142 are referred to.

Filed: 1927-12-15
Abstract: 296,236. Pugh, Ltd., C. H., and Bull, G. r. Dec. 15, 1927. Operating clutches.-In order to cushion the engagement of clutches, the operating-lever, which is adapted to be moved laterally from its normal path into a retaining-notch &c. to hold the clutch open against its spring, comes into contact with a dashpot plunger on being restored into its normal path. As applied to a motor lawn-mower, the lever 2 is movable in a guide-frame 3 hung beneath the handle-bar 4, the guide having an offset recess 5 with a lip 6 for holding the lever out, and carrying in lugs 9, 11 the liquid or pneumatic dashpot-cylinder 8. The guide-frame 3 and handle-frame 19 are held in place on the central rod 12 of the handle-bar by nuts 18 and spacing-levers 13 - - 17, the sleeve 16 having a nose 20 to retain the cylinder 8. The pneumatic dashpot shown comprises a headed stem 22 carrying the piston 21, which is connected by a tension spring 23 to a disc 24 cupped between the cylinder and a shoulder 10 on the lug 9. A loosely-fitting screw 26, bedding on a washer 28 and having a springy loching-tongue 29 engaging serration 30 on the cylinder head, forms an adjustable vent. The Provisional Specification describes the invention as applicable also to a motor-vehicle clutch pedal, the dashpot plunger being " operatively connected " thereto.

Title: Joints for oil-insulated high-tension electric cables
IPC: H02G15/24
Filed: 1947-12-24
Abstract: 633,594. Cable joints. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE KABELFABRIEK. Dec. 24, 1947, Nos. 34146 and 34147. Convention dates, July 5, 1940 and May 7, 1941. [Class 38 (i)] A joint for hollow oilfilled cables 1 comprises a clamp 2 surrounded by insulation 11 built up to provide open spaces in which the cable conductors are bowed out at the ends of the clamp and provided with channels 6, 7, 8, 9 communicating with the space outside the joint insulation. The conductors are bent out between rings 3, 4, which retain them in position during the drawing-in process, thereby permitting the oil flow through the spaces into the cables and are surrounded by perforated equipotential screens 5. In a modification (Fig. 2, not shown), one space replaces the two spaces and extends across the clamp which then bisects it, and an insulating spacer may be provided around the joint in the vicinity of the clamp to centre the assembly in the cable sheath.

Title: Improvements in or relating to coded information analysing arrangements
Inventor: COOKE-YARBOROUGH EDMUND HARRY
IPC: G06F11/34
Filed: 1964-08-20
Abstract: 1,123,612. Circuits employing magnetic storage elements. ELECTRIC & MUSICAL INDUSTRIES Ltd. 17 Aug., 1965 [20 Aug., 1964], No. 34181/64. Heading H3B. [Also in Division G4] Three transfluxors are used to store each binary digit in a store (Fig. 11), for 256 words of 16 digits each. Two of the transfluxors in each group are for data storage and the third (dummy) for noise suppression. Binary 1 is stored by one of the data transfluxors being set whilst the other is blocked and binary 0 is stored by the reverse condition. The arrangement facilitates non-destructive simultaneous comparison of all the words stored with an incoming word in a register and thus functions as an associative store. One or other of the interrogate 1 and interrogate 0 pairs of wires 32 is selected for each digit position of the words according to whether the incoming word has a 0 or a 1 in that position. Accordingly pulses are generated in sense wires 28 (one for each word) in all cases except where there is an exact match. The sense wires 28 pass through the dummy transfluxors which are always blocked as well as the data transfluxors. Fig. 6 (not shown) gives the blocked condition (binary 0) and Fig. 7 the set condition (binary 1). Interrogation is by means of a prime pulse followed by a read pulse. The prime pulse produces the condition of Fig. 9 (not shown) in a blocked transfluxor and the read pulse then returns same to its original blocked condition. The flux in a set transfluxor is not affected by interrogation. To prevent an interrogation signal acting as a set pulse on a blocked transfluxor the major aperture is continuously subjected to a small bias ourrent.
