Title: A co-ordinate switch
IPC: H03K17/97
Filed: 1960-10-14
Abstract: 932,062. Electric selective-signalling systems. KIENZLE APPARATE G.m.b.H. Oct. 14, 1960 [Oct. 23, 1959], No. 35295/60. Class 40 (1). [Also in Group XXXIX] A co-ordinate switching array comprises n sets of m soft iron cores 10 having n members 11 ... 13 adjustable to saturate m-1 of the cores. As shown, the members 11 ... 13 are troughshaped permanent magnets, all m-1 cores lying in the trough, the remaining core however lying between notches in the sides of the trough so that it is not saturated and is therefore capable of transmitting by transformer action a pulse from (say) lead 1 to lead C. The troughs are slidable so that the notches may be opposite any of the m cores. In use in an arrangement for transmitting numbers the sliders 11 ... 13 are set in accordance with the values of successive denominations and the conductors 0 ... 9 are pulses successively. Conductors A ... C thus receive pulses in time positions denoting the value of the digits of the associated denominations. In a second embodiment, Fig. 5, the arrangement is used to allocate an incoming number of different decimal positions. Thus an incoming number, say 521, represented in this case by trains of pulses is applied to leads A, B, C, and with the slides positioned so that transformer action takes place at the ringed points, the respective digits are taken out in positions B, C, D. With such an arrangement, the three sliders may be unified into a single assembly.

As shown, head 86 is attached to endless conveyer chairs 96 (and 97), Fig. 7 (not shown) which also carry masking curtains 146, 147 into position adjacent the exposure station 109 which is formed by a vacuum holder 55. The film is exposed to an original in a holder (31),Fig.1 (not shown), using lamps (36) and a luminescent panel (37) for main, bump and flash exposures, a selected half-tone screen 252 being optionally used during exposure. After exposure the film may be advanced by rollers 57, severed by blades 161, 162 and transported by perforated vacuum belts 174, 177 and cam-operated grippers 194 to a processor 61. Head 86 may rewind the film so that a different roll can be used. The exposure programme is pre-set by the operator and controlled by magnetically actuated switches and counters and ultrasonic film detectors. Panel lights (309, 314, 318), Fig.3 (not shown), may indicate the progress of the operation. Cut film may be manually inserted in holder 55.

The gyro vertical 15 is pivoted about a transverse axis 14 in the ring 7 and is connected to the support 23 by a pair of links 38 which effect stabilisation of the magnetic compass about the transverse axis. Stabilization about the fore and aft axis is effected by the connection 18 between the frame 19 and the stabilized ring 7.

Title: Preparation of metal cyanates
Inventor: PREE DAVID OTTO DE
IPC: C01C3/20
Filed: 1955-12-13
Abstract: A metal cyanate (or thiocyanate) is produced by interacting the metal, in finely-divided form, and urea (or thiourea), preferably in stoichiometric proportions, in the presence of an inert dispersing medium.  Metals specified are those of Groups IA and IIA of the Periodic Table.  A substantial proportion of the particles may be below 20 microns in size.  The dispersing medium is a liquid which is inert with respect to the reactants and reaction products.  The liquid preferably has a boiling point, e.g. 110-160 DEG  C., such that it is not necessary to resort to pressure operation or reflux conditions but such that it may be readily driven off from the reaction mixture.  Liquids specified are octane to octadecane; octene and nonene; methyl cyclohexane; toluene, xylene, ethyl benzene, mesitylene, p-cymene and tetralin; heavy alkylates and mineral oils. The metal dispersion may be formed before or after incorporating the urea in the reaction mixture.  The reaction mixture may be heated to a temperature between 60 DEG  C. and the b.p. of the dispersing medium to initiate the reaction and then, when the reaction has subsided, further, heated first to drive off the solvent and secondly, at a temperature above the m.p. of the urea or thiourea, e.g. 140-200 DEG  C., to complete the reaction.  Hydrogen and a small proportion of ammonia is evolved in the first stage of the reaction, and ammonia in the second stage.

Title: Improvements relating to reproducing apparatus for colour television systems
Inventor: DARBYSHIRE JAMES ALBERT
IPC: H04N9/18
Filed: 1954-12-10
Abstract: 783,746. Colour television. FERRANTI, Ltd. March 12, 1956 [Dec. 10, 1954], No. 35740/54. Class 40 (3). A three-colour television image reproducer comprises two cathode-ray tubes 11, 12, the first receives two colour signals, e.g. the red and blue signals, alternately via commutator 21 and has a screen 15 with a uniform spectral distribution operated in conjunction with a colour filter 23 having red and blue areas 24, 25, Fig. 2, occulted alternately by the bars 28 of a transversely oscillating mask 26 driven in synchronism with commutator 21 by mechanism 29, whilst the second receives the third signal, i.e. the green signal, continuously and displays a green image by use of a suitable phosphor material for the screen 16 or a filter 17. Filter 23 and mask 26 are located in a non-focal position in relation to a suitable optical system (not shown) for imaging the screen of tube 11 on to a viewing screen 22 or the eye of a viewer. Mechanism 29 may comprise the drive element of a moving-coil loud-speaker. The oscillation frequency, which is of the order of 10 kc/s., is preferably synchronized with the line or frame timebase to prevent crawling colour patterns. In an alternative arrangement, Fig. 3 (not shown), the two cathode-ray tubes are disposed at right angles and their screen images are combined on a common optical axis by disposing the filter and mask system at 45 degree and forming the faces of the mask bars remote from the filter with reflecting surfaces. In this arrangement, the mask is preferably held stationary and the filter oscillated. Reference is made to the use of a mosaic filter. The invention may be used with sequentially received colour signals, the filter being operated in synchronism with the sequentially received signals and the cathode-ray tubes being blanked during unwanted colour signals.

The coating-composition is supplied through a passage 29 in the handle which divides into two passages 31, 32 extending to the two chambers 33, 34 forming cylindrical spaces on both sides of a partition 35 in the head 2. The chambers are closed by walls 36, 37 threaded on a hollow bolt 38 which in turn is threaded through partition 35 and locked by a screw 39. Each chamber is provided with a strainer 40, 41 threaded on the bolt 38. The strained composition escapes to the nozzle through a passage 12 which is connected to a bore 44 in the partition 35. The partition 35 also serves as an attachment for a needle valve 19.

Flow through a duct 10, Fig. 1, is controlled by linked flaps 11 which are operated by a lever 13 connected to the spindle 12 of one flap 11, which lever is both aligned with the lowermost flap 11 and actuated by a double-acting jack 15 through a link mechanism, the supply of fluid to the jack being controlled by a valve regulated by a signalling device e.g. pressure responsive bellows. The spindle 12, Fig. 2, has a brake drum 20 secured thereto, which drum supports a stub axle 21 that rotatably mounts a tubular member 22 connected to a torque rod 28 located between stops. The brake linings 27 are urged off the drum by a spring, not shown, which spring is overcome by a stronger one 36 around a diaphragm rod 34, the diaphragm 29 being supplied with fluid from the same source as that connected to the jack. Extension of the diaphragm compresses the spring 36 and releases the brake; in the event of a fluid failure the spring 36 applies the brake. In such circumstances the flaps may be manually moved by compressing the spring 36 through a lever and operating the spindle 12 by a handle 40. The handle 40 may be replaced by a chain operable by a spanner, preferably of the ratchet type. The spring 36 may be compressed by air, oil or electrically operated means and the brake may be of the expanding, contracting, disc or cone type. In another arrangement, not shown, an auxiliary air receiver, which is filled from a main supply, is connected to one side of a doubleacting cylinder for compressing the spring 36, the other side of the cylinder being open to the main supply; should the main supply fail the air in the auxiliary receiver will cause the brake to be applied.
