Patent GB-876792-A (GB)
Title: Improvements in and relating to multivibrators
IPC: H03K17/24
Filed: 1959-01-16
Abstract: 876,792. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 16, 1959 [Jan. 17, 1958], No. 1672/59. Class 40 (9). [Also in Group XL (c)] A multi-vibrator comprises two paths each including a gate and a bi-stable element each bi-stable element being biased to a predetermined stable state and coupled to the gate in the other path so that a temporary change in the state of one of the bi-stable elements causes current flow to alternate between the paths. The embodiment describes the application of such a multivibrator for producing an optical indication of the magnetic condition of a magnetic core, Fig. 1, shows a circuit in which the state of the square loop magnetic core 1 is indicated by the multivibrator comprising magnetic cores 2, 3 and transistors 4, 5. When core 1 is in the " 0 " state when either transistor 4 or 5 conducts the associated core 2, 3 is switched to the " 1 " state. If core 1 is changed to the " 1 " state transistor 4 conducts and core 3 is switched to the " 1 " condition. When the pulse from core 1 ceases, transistor 4 is cut off and core 3 returns to the " 0 " state a negative pulse is induced in winding 17 so that transistor 5 conducts. Core 2 is switched to " 1 " state at the end of the pulse so that core 2 reverts to the " 0 " state transistor 5 is cut off and transistor 4 conducts. Thus the multi-vibrator continues to oscillate and the lamp 10 indicates the oscillatory condition. The multivibrator may be cut off by operating the switch 30 to bias the core 2 so that it cannot be set up into the " 1 " state by the collector current flow from transistor 5 or a winding may be threaded through cores 2 and 3 to effect cut-off by a bias applied to this winding. The oscillation of the multi-vibrator may be initiated by a winding on core 2 or 3 which switch it to the " 1 " state or as shown in Fig. 3 current may be caused to flow in the collector circuit of transistor 5 by the application of a low-power pulse through diode 32. In the modification shown in Fig. 2 each transistor has a feedback between its collector and base by threading the conductors connected directly to the base electrode in Fig. 1 through the core connected to the collector of the same transistor. By this means the input signal impulse applied to core 1 may be short compared with the switching time of the magnetic cores.

Title: Improvements in or relating to control valves
IPC: F15B13/02
Filed: 1950-09-05
Abstract: 678,539. Valves. VANZO, M. Sept. 5, 1950 [Sept. 6, 1949], No. 21896/50. Class 135. In a valve structure of the kind provided with inlet, outlet, and exhaust connections and with the inletoutlet and outlet-exhaust passages controlled by separate but interconnected valve closure members, and wherein the exhaust valve closes before the inlet valve opens, the inlet valve comprises an elastic ring clamped at its centre to a carrier which moves axially with respect to the ring, and the latter co-operates with a seat adjacent its outer edge. In an embodiment 1, Fig. 1, indicates the inlet for a pressure fluid and the outlet 2 is connected to a receptacle. In the position shown, the receptacle is connected to an exhaust opening 36 through a chamber 3, passages 35 in an abutment ring 33 slidable on a spindle 22, the space surrounding the spindle where it passes through a resilient washer or seating 27, and then past a valve 21 ; and the inlet 1 is sealed off by a valve disc 9 of resilient material. When the handle 19 is raised, a cam 18 thereon depresses the valve 21 into contact with washer 27 and so cuts off outlet 2 from exhaust, and in the subsequent downward movement of the valve and its spindle 22, the washer becomes distorted and the ring 33 contacts the head of valve 9 and moves the latter away from its seating to put the inlet 1 into communication with outlet 2. In the downward movement of valve 21, a flange 37 thereon contacts two relatively slidable rings 24, 25 and moves them downwards to support washer 27. The cam 18 may be replaced by a link pivoted to the handle and to the upper end of the valve 21. In a modification, two valve mechanisms as shown in Fig. 1 are mounted side-by-side and the single operating handle 51, Fig. 3, is pivoted at 50 on the valve casing. The valves 21 are actuated alternately by a rocker arm 47 which is pivoted at 46 and has pin-and-slot engagements 56, 57 with links pivoted to the handle 51 at 52, 53. When the handle is swung to one side (the left, as shown) to operate the valves on that side, the pivots 53, 57, 50 will lie in a straight line and the handle will be locked in position.

Title: Improvements in or relating to high-frequency ovens
IPC: H03B7/10
Filed: 1958-07-11
Abstract: 894,917. Generating oscillations. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 11, 1958 [July 13, 1957], No. 22320/58. Class 40(5). In a high-frequency oven having an oscillatory circuit 3 which is excited by periodic ignition pulses which fire thyratron 1, the ignition pulses are derived from a relaxation oscillator 14, 15, 16, and a relay, which may be a thermionic valve 25 as shown, receives a control voltage from a coil 31 and rectifier 30 which is dependent on the load 8, the arrangement being such that when the load falls below a given value the relay operates to increase the time constant of the relaxation oscillator. Valve 25 is normally cut off by negative bias from source 26, and when the positive control voltage from rectifier 30 overcomes the negative bias valve 25 conducts and relaxation capacitor 16 is shunted by resistor 28 and valve 25. The frequency of the ignition pulses may thus be decreased by a factor of ten and the power consumed by the oven is decreased accordingly. In an alternative embodiment, Fig. 2 (not shown) valve 25 is replaced by a normally non-conducting thyratron which is shunted by a capacitor which is normally maintained charged through a rectifier connected in place of resistor 28. When the thyratron is fired by the control voltage, capacitor 16 and the additional capacitor are discharged in parallel through the thyratron to increase the time constant of the relaxation oscillator. The ignition pulses are produced at the most favourable instants in the oscillatory cycles of circuit 3 by the circuit disclosed in Specification 843,322.

Abstract: 638,523. Television transmitters. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 27, 1946, No. 22399. [Class 40 (iii)] In television transmitting apparatus for scanning a film moved continuously past a scanning gate, images of separate portions of the gate are projected by optical means on to two contiguous and non-overlapping portions of the photo-sensitive electrode of an image dissector, or on to the photo-sensitive electrodes of two separate image dissectors, in such a way that each complete frame of the film is scanned twice during its passage through the gate and the scannings of the frame are arranged to be interlaced. As shown in Fig. 1, the images of the film gate 2 are projected by separate lens systems 10, 11 so that on the photo-electrode 7 the effective portions of the image are B1, A1 and C2, A2 corresponding respectively to the portions AB and AC of the gate 2. In explanation of the operation, if the frame dividing line X of the film 1 is at the centre point A and the image of A is at A1, the line X will, in <1>/50 second (assuming that twenty-five frames pass the gate in one second) have moved to C and the dividing line Y will have moved to B. Also the scanning of the electrode 7 will have reached B1 which is the image of B so that the frame XY will have been scanned once. At the beginning of a further period of <1>/50 second the image of X at C will be at C2 and at the end of this period the dividing line Y will be at A and its range at A2 so that with the movement of the scanning operation from C2 to A2, the frame XY will have been scanned a second time by the movement 'of the scanning beam over the portion C2, A2 of the photo-electrode. In practice, the points B1, C2 will be contiguous, and if the scanning of the dissector comprises an odd number of lines the scans of the portions A1, B1 and C2, A2 can readily be interlaced. In a modification, Fig. 3 (not shown), the dissector 6 of Fig. 1 is replaced by a twochannel dissector comprising in effect two dissectors within a common envelope, and in a further modification, Fig. 4 (not shown), the images of the upper and lower halves of the film gate are projected on two separate dissectors with their axes arranged at an angle, preferably a right angle, to each other. In the arrangements comprising Figs. 3, 4 the outputs of the image dissectors are switched to obtain the outputs corresponding to the successive images of the film frame. Specification 475,032 is referred to.
