Title: Improvements relating to the manufacture of naphthyl ketones
IPC: C07C45/46
Filed: 1945-05-10
Abstract: Alkyl and aryl-1-naphthyl ketones are prepared by reacting in a liquid medium comprising a chloro- or bromo-paraffin of specific inductive capacity not less than 5 nor greater than 12 at 20 DEG  C., a separately made complex compound of a Friedel-Craft reagent and a carboxylic acid halide or anhydride, with naphthalene or 1-methylnaphthalene.  In examples (1), (3), (6), (7) and (8) methyl-1-naphthyl ketone is prepared by adding a solution of aluminium chloride and acetyl chloride or acetic anhydride in ethylene dichloride, 1 : 2 - dibromoethane, 1 : 1 : 2 : 2 - tetrachloroethane, ethyl bromide or dichloromethane, to a solution of naphthalene in the corresponding bromo- or chloro-paraffin; (2) and (4) phenyl-1-naphthyl ketone and 1-(b -naphthoyl)-naphthalene are obtained similarly using benzoyl chloride or 2-naphthoyl chloride and aluminium chloride in p  ethylene dichloride; and (5) 4-(b -naphthoyl)-1-methylnaphthalene is prepared by adding 1-methylnaphthalene to a solution formed by adding 2-naphthoyl chloride dissolved in ethylene dichloride to a suspension of aluminium chloride in ethylene dichloride.

Title: Apparatus for shifting digital data in a register
IPC: G06F5/01
Filed: 1971-04-29
Abstract: 1343643 Shift registers GOODYEAR AEROSPACE CORP 29 April 1971 [1 June 1970] 12056/71 Heading G4C A shift register comprises 2<SP>P</SP>-1 stages where 2<SP>P</SP>-1 is greater than 14 and a shift of any magnitude may be effected in p shift operations. The shift register comprises 15 one bitbi-stable stages (Fig. 1, not shown) R1-R15, i.e. n = P = 4, and a shift may be effected in four shift operations. Each one bit stage has an output Q and, when input C is pulsed, the stage is set or reset from a first or second input A or B depending on whether input SA or SB respectively is binary 1. The desired shift is entered in binary code in shift count register C0-C3, the highest stage of which is connected to lines XY connected in turn to inputs SA, SB. Clock pulses move the bits in the register C0-C3 to the stage C3 in succession which controls the settings of SA, SB in four shift cycles and, each cycle, the inputs C are pulsed. The interconnections of stages R1- R15 ensure the correct shifting result after four cycles (Fig. 3, not shown). The interconnections of R1-R15.-To achieve the desired result the following interconnections are made: (1) For the ith stage of R1-R15, if i is less than 2<SP>P-1</SP> (i.e. 7 or less) then the Q output of stage i is connected to the B input of stage R(2i) and the A input of stage R(2i + 1), i.e. the Q output at R3 is connected to the B input of R6 and the A input of R7. (2) If i is between 2<SP>P-1</SP> and (2<SP>P-1</SP>-1) (i.e. 8 to 14) then the Q output of stage i is connected to the B input of stage R(2i-2<SP>P</SP> + 1) and the A input of stage R(2i- 2<SP>P</SP> + 2). i.e. The Q output of R10 is connected to the B input of stage R5 and the A input of stage B6. (3) The Q output of stage R(2<SP>P</SP>-1) (i.e. R15) feeds the B input of stage R(2<SP>P</SP>-1) (i.e. R15) and the A input of stage R.  Situations (1), (2) and (3) can be mathematically expressed. For all positive integers i, less than 2<SP>P</SP>, the Q output of stage R(i) feeds the B input of stage R(j) and the A input of stage R(k) where J # 2i MOD (2<SP>P</SP>-1); (K # 2i + MOD (2<SP>P</SP>-1).

Title: Water-insoluble monoazo-dyestuffs and process for their manufacture
IPC: C09B29/20
Filed: 1962-03-29
Abstract: The invention comprises water-insoluble monoazo dyes of formula <FORM:1001706/C4-C5/1> wherein A is a radical of the benzene series which may be substituted by non-water-solubilizing groups.  The dyes are prepared by coupling a diazotized amino-benzene in substance or on a substratum (e.g. aluminium hydroxide) with 6-(21-hydroxy-31-naphthoylamino) - 2,4 - dioxo - 1,2,3,4 - tetrahydroquinazoline. The grain and tinctorial strength of the dyes is improved by coupling in the presence of anionic, cationic or non-ionic emulsifiers, by adding organic solvents to the aqueous suspension obtained after coupling and heating, or by after-treating the dry dyes or dye pastes by heating in a solvent such as nitrobenzene, o-dichlorobenzene, pyridine, formamide, dimethylformamide, N - methylacetamide or phosphoric acid tris-dimethylamide. The dyes are red to brown pigments used in printing colours and lacquers or to dye rubber, paper, polyvinylchloride and textiles.  The preparation of the dyes is described in examples.

Filed: 1936-05-01
Abstract: 474,397. Fluid - pressure brakes. BAKER, W. S. GRAFF-, STAFFORD, H. A., and LONDON PASSENGER TRANSPORT BOARD. May 1, 1936, No. 12389. [Class 103 (i)] In train deceleration control devices of the kind comprising a tube containing mercury which acts as an inertia mass and co-operates with electric contacts to control the braking action, the tube is carried by a support which is capable of initial adjustment to vary the mercury level for determining the maximum deceleration to be permitted. An annular tube 9 containing mercury 30 at its lower part is mounted in an annular recess in a support 2 which is pivotally secured by a bolt 3 to a plate having lugs or brackets 27, 28, 29 for attaching the device to the vehicle. Contacts 18, 19 arranged respectively to be normally immersed and above the level of the mercury are connected by leads 22, 23 to terminals 24 on the support 2. The degree of deceleraton at which the contact 19 becomes immersed to control the brake is determined by the angular position of the support 2 which is held in the adjusted position by a clamping bolt 6 and slot 8. A restriction 17 in the tube prevents undue oscillation of the mercury and the inclined recess or pocket provided by the protrusion 21 through which the contact 19 enters the tube ensures a quick break action. The forward part of the tube may, as shown, be of smaller bore than the rear part to give a quicker rise of the mercury. The upper part of the tube may be filled with inert gas to prevent action on the mercury or contacts if sparking occurs. A number of contacts may be arranged on the forward side of the tube. Two of the devices are shown mounted each on one side of a supporting plate so as to be capable of separate angular adjustment and the contacts 19 may be arranged at different levels in the two tubes so that the two circuits are completed at different degrees of deceleration, the one being arranged to cut off the pressure fluid supply to the brake cylinder, and the other to vent the cylinder.
