Title: Method and means for obtaining synchronism between cinematographic projections and radiotelephonic emissions
IPC: G03B31/02
Filed: 1924-03-22
Abstract: 213,282. Delacommune, C. E. E. March 24,1923, [Convention date]. Receiving systems and apparatus; controlling kinematographs. - Synchronism between projected kinematograph images and music, speech, &c., transmitted radio-telephonically to the projection hall, is maintained by means of an indicating band driven in conjunction with the projector; the projector operator, orchestra leader, or other person, listens to the transmitted music &c. and adjusts a control device such as a rheostat in the driving circuit of the projector and indicating band so as to vary their speed accordingly. As shown, a receiver A for radio-telephony is provided with an amplifier B, a loud speaker C, preferably placed at the bottom of the projection screen, and a telephone D which is worn by the control operator. The indicating band I, driven in conjunction with the projector F, passes from a drum r to a drum r<1> over a ground glass plate G having a transverse transparent line g which is situated above a lamp H and enables the indications on the band to be read. The speed of the projector is controlled by either or both of two rheostats K, K<1> so placed as to be operable respectively by the projector operator and the orchestra leader. The indications may be arranged obliquely across the band so as to reduce the length required. Signals such as numbers may be transmitted to the projection hall before the picture exhibition and during intervals in the music &c. so as to facilitate synchronization. To prevent such signals from being audible to the spectators, an electromagnetic circuit-breaker K is provided in the amplifier circuit and is operated automatically by means of contact levers controlled by slots in the band. A second band, observed by the orchestra leader, or lamps, bells, or other signals, may be similarly operated from the band I. The band I be dispensed with, notches, perforations, or images on the film itself, being then provided to facilitate synchronization. The transmitted music, e.g. a song, may be accompanied by orchestral or other music being performed at the hall. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of transmissions on a different wave-length for transmitting signals or for automatically controlling the projector. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric furnace arrangements
IPC: H05B3/00
Filed: 1951-04-04
Abstract: 700,251. Supply systems for consumption apparatus; transformer arrangements. SOC. DES ELECTRODES DE LA SAVOIE. April 4, 1951 [April 6, 1950], No. 7860/51. Class 38 (4). [Also in Group XI] In electric furnaces having heating resistor rods which age and have a resistance increasing with use, e.g. of silicon carbide, the voltage of the current supply to each element is separately adjustable through separate tappings on a transformer secondary. Current is supplied through a transformer which may be an autotransformer having as secondary a winding in at least two coils 10, 10a joined at a common point m. Taps 1-6 are similarly spaced on each coil 10, 10a and with the common point m are connected to a series of parallel bars 13, 13a, 13m extending perpendicularly to a second series of bars 14, 14a grouped by pairs, each pair being connected to opposite ends of a heating resistor rod 15. The first series of bars is insulated from the second series, but connection is made between them at the crossing points by connecting pins, which are so placed that the current supply to each resistor 15 is separately adjustable. The intervals between the voltages of successive taps 1-6 of the secondary and the common point m are in geometrical progression with a ratio of <SP>n</SP>#2 where n is the number of taps on each winding. The bars 14 of the second series extend wholly across the space occupied by the bars 13. The connecting pins are preferably placed so that the load on the two coils 10, 10a is equal. Thus the bars 14 of each pair may be connected to the coil 10, while the bars 14a are arranged for connection to the coil 10a. One end of the resistor rods may be connected through the bar 13m to the common point m. With single phase current, the bars may be arranged as in Fig. 3, the bars of the second series being arranged in two groups of pairs 14, 14a of equal or approximately equal number ; and the bars 13 of the first series are divided into two fractions each co-operating with the bars of one of said groups, the connections between the bar fractions being crossed so as to even the load on the two coils. With a three phase current, the three secondary coils are arranged in Y form, Fig. 9 (not shown) and the bars of the second series are divided into three approximately equal groups of pairs 14, 14a and the bars 13 of the first series are divided into two fractions, one co-operating with the bars of one of said groups, and the other fraction with the other groups ; and the connections between the fractions are so arranged that a bar fraction connected to a tap of the first secondary coil co-operates with bars of the first of said groups, a bar fraction connected to the second coil cooperates with the second group and a bar fraction connected to the third coil co-operates with bars of the third group.

Title: Improvements relating to thin film magnetic stores
Inventor: WELBY REGINALD SIDNEY
IPC: G11C5/08
Filed: 1968-02-17
Abstract: 1,262,862. Magnetic storage arrangement. EMI Ltd. 15 May., 1969 [17 Feb., 1968], No. 7876/68. Heading H3B. In a magnetic storage arrangement, thin film magnetic elements 18 are disposed in an array adjacent the crossing points of two sets of parallel insulated conductors 2, 3 printed on to a conductive substrate 1, the conductors 2, 3 being tapered along their lengths and terminated by resistive strips 9, 13 respectively. The conductors 2, 3 are preferably exponentially tapered, their widths increasing by 50% along their lengths to offset the effects of eddy current damping on pulses flowing in the conductors. The resistive strips form lossy transmission lines, and are as described in Specification 1,262,863 matching by strips 9 and 15 being completed by dummy conductors 10, 16 terminated at both ends by resistors 11, 17. The sets of conductors 2, 3 serve as digit drive/sense and address conductors respectively, input to the address conductors being to points 12 via terminals 14 and drive amplifiers 13, while input to the drive/sense conductors is to points 4 via terminals 6 and drive amplifiers 5. Sense amplifiers 7 are also connected to the drive/sense conductors at 4. The magnetic elements 18 may be between the substrate 1 and the conductors 2, 3, or as described in co-pending Application 7877/68. The arrangement may be produced by vapour deposition in vacuo, a mesh being interposed between the surface on which deposition is to occur and the source of deposited material. The mesh, which may have areas of different transmissive properties for the vapour, should have fine holes to prevent patterning, or may be vibrated. The store may include several planes, and the conductors may taper over these planes.

Abstract: 1,253,871. Transistor multi-stable state circuits. RESPONSE SYSTEMS CORP. 14 Feb., 1969 [16 Feb., 1968], No. 8088/69. Heading H3T. [Also in Divisions G4 and G5] In a machine-teaching system employing electric selective signalling (see Divisions G4- G6) a five-stage flip-flop circuit is used (a) to signal which one of five possible answers to a question has been selected by a student and (b) to signal five-bit numbers representing letters of the alphabet. Fig. 11 shows, at 230, one stage of this circuit. Normally a positive voltage on either one or neither of lines 250 and 252 will prevent one of the transistors 240 or 242 from conducting or, if both lines are energized, each transistor will cut off the other. In any case there will be no output to units 236 and 234 nor to line I 1 . If however contact 232 is made while both lines 250 and 252 are energized, both transistors will conduct and remain conducting even when contact 232 is broken, so long as lines 250 and 252 remain energized. This will provide an output signal to line I 1 . Four other identical stages, connected to further output lines I 2  and I 5  (Fig. 9, not shown) are connected in parallel with the one shown. However the presence of a constant-current circuit 220 in the line 250 ensures that only sufficient current can be supplied to energize the transistor 240 of one stage. Hence, once one stage has switched to its conducting state the others cannot. In use, the set of five contacts 232 (one for each stage) are employed by students to select an answer to a question. Means by which the same multi-stage flip-flop can be employed by students to signal alphabetical characters in succession and thus spell out their names for recording, along with their answers to a set of questions, is disclosed in the Specification and is abridged in Division G4-G6.
