Patent GB-632821-A (GB)
Title: Process for the production of substituted thiophanes
Filed: 1947-05-21
Abstract: Substituted thiophanes are obtained from 1 - nitro - 2 - halogen - 2 - alkyl - ethanes, where the alkyl group may carry a hydroxyl, alkoxyl, halogen, formyl, carboxyl, carbalkoxyl, carbamido or cyano substituent, by condensation with mercapto-acetal and alkali to substituted diethyl sulphides; the acetal group is hydrolyzed to the aldehyde group with an acid and the product ring closed with a base to a 2-substituted-3-nitro-4-hydroxy-thiophane; the nitro group is finally reduced to an amino group.  The base used for ring-closure may be inorganic (other than ammonia), e.g. potassium hydroxide, or organic, e.g. sodium methoxide or a tertiary base such as trimethylamine.  The final reduction may be effected with aluminium amalgam and ether, or with iron or zinc with hydrochloric or acetic acid.  Examples show the process where the alkyl group is (1) methyl, and (2) o -carboxybutyl.  The products are useful for the preparation of compounds of the biotin type.  Mercapto-acetal may be obtained from bromo-acetal and potassium hydrosulphide in alcoholic solution. The Specification as open to inspection under Sect. 91 states that 2 - methyl - 3 - amino - 4-hydroxy-thiophane may be converted into a mixture of stereoisomeric hydrochlorides and similarly a mixture of picrates.  On treatment with phosphorus pentachloride it yields 2-methyl - 3 - amino - 4 - chloro - thiophane and this in turn is converted by ammonia into a mixture of stereoisomeric forms of 2-methyl-3 : 4-diamino-thiophane, which gives a hydrochloride. It is also stated that semi-ester acid chlorides of adipic acid are reduced with hydrogen and precious metal catalysts in toluene or xylene solution to the corresponding semi-ester aldehydes, which with nitromethane and phosphorus pentachloride give 7-nitro-6-chloro-heptane, 1-acid esters, and these may be used as starting materials.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in display-controlling means for cathode ray tubes
Inventor: LAWS CECIL ALFRED
IPC: G09G1/12
Filed: 1953-05-18
Abstract: 736,557. Photo-electric waveform generators. ELLIOTT BROS. (LONDON), Ltd. May 14, 1954 [May 18, 1953], No. 13954/53. Class 40 (3). [Also in Group XL (c)] In an arrangement for displaying predetermined patterns or symbols on the screen of a display cathode-ray tube by simultaneously varying the displacement voltages applied simultaneously to the X and Y plates of the tube, the X displacement voltage is generated by rotating a transparent disc 1 between an auxiliary C.R.T. 12 and a photo-cell 13, the disc having an opaque annular track 2 whose outer contour corresponds to the required variation of the displacement voltage and the output from the photo-cell 13 being applied through an amplifier 14 to control the deflection of the beam of C.R.T. 12 so that the luminous spot on the screen of C.R.T. 12 is maintained at the outer edge of the track 2 ; the output from amplifier 14 thus constitutes the required displacement voltage and is also applied to the X plates of the display C.R.T. (not shown). The Y displacement voltage is generated by a similar arrangement comprising a disc 1a, discs 1 and 1a being driven by a single motor 11. When a plurality of different patterns are to be displayed sequentially in displaced positions, the pattern contours 3 ... 8 are arranged end-toend along the track and disc 1a includes an additional track 15 comprising alternate opaque and transparent areas which in conjunction with lamp 16 and photo-cell 17 produces a control voltage which operates switches for applying the shift voltages to the plates of the display C.R.T. ; alternatively the switches may be controlled by a further contour-following C.R.T. Brightening pulses may be generated in a similar manner.

Boring or turning apparatus comprises a turn-table which is rotatably mounted on a base structure, and a separate machining unit to effect turning or boring operations on a workpiece mounted on the turn-table, the machining unit being adapted to be mounted in a number of positions relative to the turntable by securing the unit in selected ones of a number of supports on the base structure. The turn-table 2 is mounted on a seat 3 for rotation about a pivot 4. The pivot houses a piston 6 with a tapered centering portion 7 and carries a post 10 to which machine ports are attached. Hydraulic pressure applied to the bottom face 8 of the piston is regulated to counterbalance the weight of the post and machine ports. A carriage 11 attached to the post 10 receives a tool-holder 12 which is movable along the carriage transversely to the pivot axis 9. A carriage 13 is coupled to the carriage 11 and which moves along the axis of the post. The upper end of the post is centred and secured to a beam 22 which rests on and is secured to frames 24 and 25 which are movably supported on beds 28 and 29 to facilitate adjustment of the post and beam and allow the retraction of the frames to permit the removal of the workpiece. Access to the tool slides and holders is provided by ladders and walkways 34 to 37. The slides and feed screws for the carriages 11 and 13 are protected by expanding covers 17 and 18.

Filed: 1919-06-04
Abstract: 139,966. Wales, H. N., and Bennell, A. June 4, 1919. Cleaners for tobacco pipes and cigar and cigarette holders.-A boiler a, heated by a burner b, is supported by a vertical sliding rod a<1> resting on a balance lever c which is mounted on three knifeedges or pivots e', e<2>, e<3>, and is provided with a counterweight d and a rolling weight f, which are thrown into action when the boiler is pressed down, or the water in the boiler falls below a certain level. A tappet k<1> on a block on the rod a<1> acts on levers l, m to open and close a conical vave l<2> in the gas-supply nozzle b<2>. A conical plug o<1>, adapted to fit in the pipe bowl or holder, is pressed down against the force of a spring o<2> to allow steam to pass through radial holes o<4> to a central bore through the plunger o. Water is forced by a hand-pump h from a tank i through a flexible tube j past a ball valve k<3> and through a pipe p into the boiler. Excess steam passes through a safety-valve n<2> and pipe n<3> to the feedtank i. The ball f, in running along the lever c, operates a bell hammer g or the like to give an alarm. The pilot gas supply is regulated by the lever m, which is pressed against an adjustable nut m<3> by a spring m<1> and supports the bell-crank lever l, both levers being acted on by the tappet k<1>. The downward movement of the boiler, when the pipe is pressed on the nozzle, o<1>, opens the valve l<2> to admit more gas to the burner, and the upward movement of the boiler, when the waterlevel is lowered, tends to close the valve. The apparatus is mounted in a slotted casing, and a receptacle may be provided to catch the discharge from the tobacco pipe.
