Patent GB-1260871-A (GB)
Title: Still or cinematographic camera
IPC: G03B19/18
Filed: 1969-01-30
Abstract: 1,260,871. Cine cameras. AGFA GEVAERT AG. Jan. 30, 1969 [Jan.31, 1968], No.5207/69. Heading G2E. Electrically driven shutter and film transport mechanism is provided with a locking device which is released by means of an electromagnet actuated by the discharge current of a capacitor. For continuous operation, contacts 26a, 26b of a switch 26 are moved against contacts 26d, 26g and a battery 25 charges a capacitor 29. On camera release, a switch 30 closes allowing capacitor 29 to discharge through an electromagnet 1, which attracts an armature 6 fixed to a lever 10. A brake 13 on one end of lever 10 is thus moved out of engagement with a rotary shutter 20, while the other end of lever 10 disconnects contacts 22a, 22b and connects contacts 22b, 22c, which connects a drive motor 52 to the battery 25. The battery also keeps the electromagnet 1 energized for continuous operation through resistors 31, 32. On liberation of the camera release member, switch 30 opens, de-energizing the electromagnet. The brake 13 stops the shutter 20 while contacts 22a, 22b engage, switching off the motor 52 and connecting it to a resistor 28, so that the kinetic energy of the motor, is dissipated in the resistor 28. This ovictes the need for friction coupling between the motor and its drive-shaft. For single frame operation, contact 26b is moved against a contact 26 f so that only resistor 31 is in circuit with the electromagnet 1, and insufficient current is supplied thereto after the capacitor discharges. The mechanism thus operates briefly to wind on and expose a single frame. A switch 33 may be used for remote control. In an alternative embodiment Fig. 3 (not shown), the electromagnet is connected to the capacitor (41) via a transistor (36).

Each immersed battery may be completely discharged by connecting their poles. A voltage may be applied across the poles of each battery to force dissolution. Auxiliary anodes external to the batteries may be immersed in the electrolyte. Pb is electro-deposited on the cathodes and/or PbO 2  on the anodes.

Title: Improvements in or relating to subscription encoding system for color television
IPC: H04N7/169
Filed: 1955-02-22
Abstract: 766,620. Television. ZENITH RADIO CORPORATION. Feb. 22, 1955 [March 10, 1252], No. 5276/55. Drawings to Specification. Class 40 (3). Colour television signals are cooled by means of an arrangement which prevents satisfactory reception of colour pictures by unauthorized receivers (i.e. those not equipped with suitable decoding apparatus) but which allows such receivers to produce satisfactory monochrome pictures. The invention is applicable to any colour television system in which the colour intelligence information (as distinct from the luminance information) is transmitted by means of a separable carrier wave, e.g. the colour subcarrier of the N.T.S.C. system. In one embodiment applied to the latter system cooling is effected by periodically changing the frequency of the sub-carrier wave under the control of a " key " signal which is transmitted to authorized receivers and there employed to effect a corresponding change in the frequency of the subcarrier reference oscillator. In this arrangement (Fig. 1, not shown), the transmitter employs two sub-carrier oscillators, one of which may be the conventional sub-carrier wave oscillator (synchronizing " bursts " of which are transmitted in the usual manner) and the other of which operates at a frequency different from but bearing a predetermined relationship .to that of the first and synchronizing " bursts " of which are transmitted during vertical retrace periods. Coding is then effected by selectively applying the outputs of these oscillators to the I and Q modulators under the control of the key signal. At an authorized receiver (Fig. 2, not shown), the synchronizing " bursts " are employed to control the generation of similar colour reference frequencies and there are selectively applied to the I and Q demodulators under the control of received " key " signals. In this manner a satisfactory colour picture is reproduced by receivers equipped with the appropriate decoding apparatus and in receipt of the " key " signal. In the absence of the latter apparatus and/or of receipt of the " key " signal or with a non-colour receiver a satisfactory monochrome picture may be reproduced since the cooling arrangement does not affect the luminance component of the transmitted composite signal. In a second embodiment (Figs. 4 and 5, not shown), cooling is effected by periodically varying the phase of the colour sub-carrier now employed at the transmitter and decoding at the receiver is effected by producing a compensating variation in the phase of the local colour reference wave generators under the control of a " key " signal as in the arrangement described above. In each of the embodiments the " key " signal may be sent to selected receivers by any means, e.g. by telephone line or as part of the composite transmitted signal or, alternatively, instead of employing a " key " signal, co-ordination of the transmitter and receiver may be. achieved by means of punched-card code schedule devices or similar arrangements.

Sand moulds and cores are reinforced by introducing organic fibrous material impregnated with a solution of an intermediate condensation product and then hardening this into an insoluble resin, or the hardening may be effected before its introduction. The fibrous material may comprise string or rope of jute, &c., or a textile sheet of natural or artificial fibre which may be folded or rolled and the condensation product a solution in water of metholurea or a soluble phenolaldehyde condensation product. A hardening accelerator, e.g. boric acid, may be added. The impregnation may be effected by dipping and the material may be first wetted with the solvent. The flexible material may be threaded into a mould or core after attaching it to a piece of wire which acts as a needle. Hardening of the resin occurs in this case during stoving of the mould, &c., and some of the solution may percolate into the sand itself before it hardens. Whether the hardening is effected before or after inserting in the mould, a textile-covered wire, e.g. of steel, may be used in place of mere fibrous material.
