Title: Improvements in or relating to devices for breaking electrical current supply to a load
IPC: H01H37/66
Filed: 1959-10-02
Abstract: 906,992. Thermal switches. PECAZAUX, M., and KREUTLER, R. Oct. 2, 1959 [Oct. 2, 1958], No. 33519/59. Class 38 [5). [Also in Group XXXVIII] A switch, especially for controlling flashing vehicle indicators, comprises a movable contact carried by an elongated armature which is supported for angular movement in a plane through its longitudinal axis, the armature cooperating with permanent magnet poles in each of two operated positions to hold the contact in such positions until the magnetic force is overcome by an electrically actuated driving means. In one form, Fig. 1, a bimetal strip 1 carries the armature 3, which is arranged between poles 7, 8. Normally, the movable contact 4 engages a contact 5 and the load 6 (e.g. a vehicle signalling lamp) is energized. Current through the strip 1 causes it to deflect to separate contacts 4, 5 when the force of pole 7 is overcome, and when the strip recools, the force in the strip eventually overcomes pole 8 and the contacts reclose. The poles may be the North and South poles of a single magnet or may comprise two poles of two magnets, Figs. 2 to 5 (not shown). The bimetal strip may be replaced by a " hot wire," Fig. 6 (not shown). An indicator lamp may be arranged in parallel with the element 1 and the contacts so that it lights when the lamp 6 is extinguished, Fig. 7 (not shown), or a low power indicator lamp may be arranged in parallel with the lamp 6 so as to indicate failure of lamp 6, Fig. 8 (not thown). A stop 9 may be connected to the indicator lamp which then flashes alternately with lamp 6, failure of lamp 6 causing the indicator lamp to remain unlit, Fig. 9 (not shown). Two lamps 6 may be arranged in parallel, Fig. 10 (not shown). In any arrangement, the armature may be forked to embrace a bar magnet, Figs. 11, 12 (not shown).

[Also in Division G3] Apparatus for coiling spring wire includes a single, narrow, freely rotatable, axially-displaceable guide roller 6 which controls the pitch as the wire 1 is wound on to a pin 2. The guide roller 6 is moved axially by either an hydraulic cylinder 7 with control valves, or with a proportionating pump or by a lead screw and is braked by means of a coupled hydraulic pump 8 or an electric eddy-current brake to produce the required tension in the wire. In one embodiment the guide roller 6 is variably inclined using double pistons 9 which tilts the guide roller through a desired angle α. The guide roller 6 is controlled by electronic digital processing and measuring apparatus which comprises a data carrier containing data representative of the pitch of the spring, and an electronic store arranged to hold data specifying all parameters of the spring and controlled by timing signals from a pulse transmitter arranged to operate in dependence on the angle of the rotating pin to feed control signals to a control member for the guide roller via a translator and an amplifier.

Title: Image-reproducing system for a television receiver
IPC: H04N5/16
Filed: 1963-09-03
Abstract: 1,012,502. Television. HAZELTINE CORPORATION. Sept. 3, 1963 [Sept. 13, 1962], No. 34740/63.- Heading H4F. In a television image-reproducing system the video signal (from amplifier 15) is applied to the cathode-ray tube 17 via a capacitor 24, whereby only the alternating-current components are passed, the system including a circuit 26 connected in the beam current path of tube 17 which responds to the applied signal and functions to maintain correctly the black level in the reproduced image for scenes of low average brightness and to suppress correct black level reproduction to some degree for scenes of high average brightness. The circuit includes a triode 18 which is connected in the cathode circuit of tube 17 and receives the applied signal on its cathode by way of capacitor 35 and a connection which includes a diode 33. The cathode bias established by elements 27, 28, 34 and 33 is such as to cut off the triode in the absence of a signal. The circuit functions as an average detector of the negative (i.e. " white " direction) excursions of the video signal with respect to its mean or A.C. axis. The average beam current in the tube 17 varies correspondingly and it is demonstrated (with reference to Fig. 2, not shown) that the average current increases progressively from scenes of low to medium brightness and then falls for scenes of high brightness. As a consequence the black level is reproduced correctly only for scenes up to a medium level of brightness. In effect the system provides a form of signal coupling which changes from D.C. to A.C. transmission. Overloading of the C.R. tube E.H.T. supply is prevented on scenes of high brightness, and by virtue of the averaging operation the system is insensitive to noise. According to modifications the relative values of resistors 28 and 34 may be selected and diode 33 may be omitted so as to obtain a circuit operating with a degree of peak detection, whereby the characteristic of the system (i.e. the extent of correct D.C. reproduction) may be varied from that obtained with average detector operation.

A tubular combustion chamber of the kind constructed from flat-sided tubes sealingly secured together side-by-side throughout their lengths and through which coolant is passed, includes a pipe communicating with the interior of the combustion chamber through a transverse aperture formed through at least one of the tubes, the pipe being bounded by two part-annular non-communicating chambers extending throughout substantially the whole length of the pipe, one of these chambers communicating with the downstream end of the upstream portion of each tube interrupted by the pipe and the other chamber communicating with the upstream end of the downstream portion, coolant being extracted from the upstream portion through the one chamber and further coolant being introduced into the downstream portion through the other chamber at such pressure that the rate of heat transfer through the upstream and downstream portions is substantially the same as through corresponding portions of an uninterrupted tube. A combustion chamber for a MHD generator, constructed as described in Specification 1,195, 022 from flat-sided tubes 1 sealingly secured together throughout their lengths, comprises a pipe 5 communicating with the interior of the combustion chamber and interrupting several of the tubes. The pipe 5 may be used for passing a fluid into or out of the combustion chamber or may contain an inspection window of quartz &c. or a transverse wall apertured to receive a probe.

Coolant (e. g. water) flowing through the upstream portions 1a of the tubes 1 interrupted by the pipe 5 passes through the chamber 9 to an outlet connection 14. Fresh coolant is introduced via an inlet connection 15 and the chamber 10 to flow through the downstream portions 1b of the interrupted tubes 1. The rate of flow through the portions 1a, 1b is such that the rate of heat transfer is substantially the same as for the corresponding portions of the uninterrupted tubes 1.
