Title: Improvements in variable pressure systems
Inventor: HUNT CLAUDE JOHN LANCELOT
IPC: G05B19/06
Filed: 1969-04-26
Abstract: 1,268,651. Stopping in predetermined positions. C. J. L. HUNT. 24 July, 1970 [26 April 1969; 28 Aug., 1969], Nos. 21396/69 and 43013/69. Heading F2L. [Also in Divisions F1 and G3] The cyclic operation of a vacuum metallizing plant is effected by a cam controller, or a plurality of interlocked cam controllers, stepped by a solenoid device connected in a circuit arrangement whereby the carrying out of certain cyclic steps is determined by the pressures attained in the chamber as sensed by a Pirani gauge and a Penning gauge. As shown, a controller, comprises a cam assembly 40, operating electric switches, mounted on a shaft 36 connected to a drum 41 in which is an axially slidable spring-loaded pin 31. Axially mounted, with respect to the drum 41, is an index plate 29 having holes, not shown, into which the free end of the pin 31 can enter. The plate 29 is mounted on a shaft 23, driven through a pulley 22, having an indexing star-wheel 30. A stationary block 39 is provided with equiangular bores in each of which an actuating pin is slidably mounted. One pin 43 is aligned with an end 44 of the pin 31, so that when pin 43 is displaced by a pivoted yoke 51, actuated through a linkage by a solenoid 45, the movement of the pin 31 frees the drum 41 from the block 39 and simultaneously causes it to rotate by engaging a hole in the plate 29. The drum then rotates until the pin is aligned with the next hole in the block 39. The cam-shaft 36 is thus rotated for an equi-angular displacement for each actuation of the solenoid 45. A plurality of controllers can be driven by a common drive and each control a specific part of the plant operating cycle.
Patent GB-430441-A (GB)
Abstract: 430,441. Switching systems for consuming devices. OUGHTON, W. E.,HYMAN, L., and HYMAN, B. E., 11, Portland Crescent, Leeds. Jan. 22, 1934, No. 2113. [Class 38 (iv)] In a time-clock controlled lighting system, the operation of the normal time-controlled switch is modified when desired to give earlier or later lighting by an auxiliary time-controlled switch. Lighting groups are switched on and off by motor relays 7 which rotate through 90‹ when the current is switched either on or off by the respective time-controlled switches 1, 2. In the left-hand system, the normal switch 2 is connected to an auxiliary switch 4 which may give different lighting times, but is only effective when the switch 6 is operated to connect the " on contact of the switch 4 to the " on " lead to the motor relay. The lights are switched on by the earliest set switch and off by the latest set switch. The light may be switched off entirely by switch 5. The auxiliary switch 4 may also be cut out by the switch 8.

Abstract: 1,086,691. Optical projection apparatus; programmed process control. M. C. BERGER. Oct.22, 1964 [Nov. 13, 1963], No. 43135/64. Headings G2J and G3N. A multi-coloured picture composition is provided by projectors M I , M II , M III , projecting from separate black and white transparencies through selected colour filters to form superposed coloured images on a common screen, the transparencies being prepared by photographing on to cine film strip a coloured original through separate colour analyzer filters of non-overlapping wavebands, the projection filters being different from the analyzer filters. Positive and negative transparencies are used and each projector comprises two lamps 12A, 12B, condensers 15 and negative and positive transparency holders 16a and 16b respectively. Either tranparency image may be projected through selected colour filters on rotatable disc 47 and objective lens 20 by means of tilting mirror 19. Alternatively, a filter strip may be used. Lens 20 has an iris diaphragm 23 and may be focused, and the projectors are pivotable on common mounting 45 to throw converging projection beams on to the screen. The colour and intensity of each coloured image may be varied on the screen until an acceptable composition is found which is then recorded by colour photography, a further photograph being made of the setting of a manual projector control panel. Automatic operation is possible by means of magnetic endless programming tapes on reels 66, 67, one for each of the three projectors used when the three primary colours are used for analyzing filters in preparing the master Images, Four signals are recorded on each tape: (a) a series of perforations which are photo-electrically sensed at 70 to energize solenoids which pivot mirrors 19. (b) a series of audio-frequency pulses which are detected at 75 to energize the one-step motors 52 to rotate discs 47 through gears 50, 51. (c) continuous or trapezoidal form signals at 1 kc/s frequency read by magnetic head 76 and used to actuate galvanometer devices 53 to set the iris diaphragms. (d) a spaced series of triangular signals, each at a different frequency and also sensed by head 76 are each passed by one of the filters 84 to 87 to energize either of lamps 12A or 12B through interlocking relays 88, 89.

Fluoroterephthali acid dichloride is prepared analogously.ALSO:The invention comprises anthraquinone dyes of formula A1-NH-CO-B-CO-NH-A2 wherein A1 and A2 are identical or different radicals of the anthraquinone series which contain substituents which do not dissociate acid in neutral water and B is a mono- or di-fluorophenylene radical bound to the carbonyl groups in m- or pposition.  They are prepared by condensing 1 mol. of a mono- or di-fluoro-iso- or -tere-phthalic acid or a bifunctional derivative thereof with 2 mols. of one or two aminoanthraquinones.  The dyes give yellow orange and brown shades on cotton.  In an example 1-aminoanthraquinone and 5-fluoroisophthalic acid dichloride are mixed and boiled in 1:2-dichlorobenzene and the dye is filtered off. Many similar examples are specified.

An inductor alternator or equivalent motor comprises a stator ring 222 of wound ferromagnetic members and a field-energizing winding 21, mounted between a pair of planar rotor members 12, 13 having ferromagnetic teeth 120, 130 arranged to be saturated by the field winding 21 and shaped so that the net flux in the rotor during operation is constant. As described, a fixed shaft 111 carries bearings 112, 113 supporting a rotor 10 of mild steel, pure iron or Fe Co. The members 12, 13 are flanged so as to carry a series of teeth 120, 130 formed by winding a narrow tape of silicon steel with a wider tape of pure iron. The tapes are cemented together by epoxy resin, after which the teeth are formed by cutting away parts of the projecting edges of the wider tape at an angle to the radius (Fig. Id, not shown) such that the area of overlap of teeth and stator members is always constant. The number of teeth on each rotor plate should be half the number of stator sections. Alternate stator windings are connected in series opposition, the resulting pairs being connected in series or parallel so as to form a single or threephase machine. The stator sections 222 are formed of packs of silicon steel laminations with the crystals oriented parallel to the machine axis.
