Inventor: BAILEY GERALD
IPC: H04N5/268
Filed: 1965-09-03
Abstract: 1,161,732. Intruder alarms. ELECTRIC & MUSICAL INDUSTRIES Ltd. 5 Sept., 1966 [3 Sept., 1965], No. 37690/65. Heading G4N. [Also in Division H4] In a system in which the signals from a plurality of television cameras are applied by commutating means successively to a monitor, means are provided for overriding (or selectively stopping the action of) the commutating means for selectively applying signals from a selected one only of the cameras to the monitor. As shown, six television cameras C1, C2 ... C6 are connected via conductors or radio links to a switch unit B which acts as an overriding switch and contains six similar switches each comprising a switch SA and a switch SB which may be actuated together by a manually operated mechanical switch shown as a dotted line. The commutating means E may comprise a rotating cam drum D connected as shown, or valve or transistor switches connected as a ring counter driven by a pulse generator, and unit B may be replaced by means switching off the motor driving drum D and the pulse generator. In normal operation the switches SA and SB are in the positions shown and excerpts of the video signals from the cameras are applied in turn via switches SB, amplifier A2 and combining network N to the monitor M. The line scans of the cameras are preferably synchronized with one another and the frame scans are preferably locked to the A.C. mains. To view the signal from camera C1 continuously switch 1 is actuated and the output of the camera is applied via amplifier A1 and network N to the monitor M, the outputs of the other cameras C2, C3 . . . C6 being prevented from reaching the monitor M because switch SB1 is open-circuited. Preferably only one switch may be actuated at any time. The overriding means may operate in response to a change in the video signal which represents the mean brightness of the scene sensed by a smoothing circuit e.g. due to the presence of an intruder. Alternatively a video signal representing an entire frame may be stored in a storage tube and subtracted from the video signal for subsequent frames, any change detected operating the overriding switch. When any change is detected an alarm as well as the overriding switch may be arranged to operate.
Patent GB-1305119-A (GB)
IPC: G11C11/41
Filed: 1970-08-05
Abstract: 1305119 Data storage INTERNATIONAL BUSINESS MACHINES CORP 5 Aug 1970 [26 Nov 1969] 37697/70 Heading G4C [Also in Division H3] A data registering system comprises at least one register stage for storing binary data and controlled by a cyclically-operable control circuit to be responsive to noisy binary data signals and to latch in signals present at its input at a predetermined time within each cycle, or to be responsive to substantially noiseless binary data signals and to be latched at the predetermined time to the condition of the signal presented at its input at an earlier time in the cycle. According as a signal M is up or down, 4 bits in parallel are sent in each bit time from a magnetic core memory 13 (noiseless data) to a data processor 12 via a data selector 31 and buffer register 10, or from the processor 12 (noisy data) to the memory 13 via the selector 31 and register 10. Selector 31 merely selects the data source, 12 or 13, and inverts each bit at 40 to compensate for the fact that the inverse 0 outputs of the register 10 feed the memory 13. However, the 1 outputs of the register 10 are used for feeding the processor 12, via gates 26, so the latter incorporates inverters (not shown) to compensate for inverters 40. The register 10 is controlled by signals D, S<SP>1</SP> produced from signals A, M, B, S. Signals A is up for the last three-quarters of each bit time, signal B is up throughout, and signal S is up for the first half of each bit time. For noisy data (M down), S<SP>1</SP> is up and D down for the first half of each bit time, during which the register outputs track the respective register inputs D1, D2, D3, D4, whereas during the last half of each bit time (by which time the noisy data levels will have reached the correct values) S<SP>1</SP> is down and D up so that the register outputs (fed back) are latched in. For noiseless data (M up), S<SP>1</SP> is up and D down for the first qarter of each bit time, giving tracking as above, but during the second quarter of each bit time S<SP>1</SP> and D are both up so that each input and its corresponding fed-back output are effectively ORed to set the respective stage, and during the last half of each bit time S<SP>1</SP> is down and D up to give latching in as before. Fig. 4 shows details of a register stage (compare Fig. 1), multi-emitter transistors 69, 70, 71 being ANDs 18, 19, 20 respectively, transistors 72, 73, 74 being OR 21, transistor 75 being inverter 22, and transistors 79, 80, 81 being inverter 23.

Title: Improvements in or relating to phase correcting networks
IPC: H04N11/14
Filed: 1957-12-06
Abstract: 847,850. Electric signal transmission systems. WESTERN ELECTRIC CO. Inc. Dec. 6, 1957 [Dec. 17, 1956], No. 38007/57. Class 40 (4). [Also in Groups XL (b) and XL (c)] A phase-corrector, e.g. for eliminating differential phase in the colour carrier of a television signal, comprises two paths connected in parallel, the paths being arranged to provide a difference in amplitude and a phase difference of either 90 or 270 degrees at the operating frequency between the respective signals, one of the paths including two or more controllable non-linear impedances. In the balanced corrector of Fig. 1 the main signal path includes an amplifier 12 and a 90 degree phase-shifting network 13. An auxiliary network 14, which may be combined with network 13, compensates for phase distortion in the amplifier 12. The second path comprises branches 15, 16 which include rectifiers 19, 20, 23, 24 arranged as shown. The two paths are connected at the output end through adjustable voltage dividers 18, 21, 25. It is stated that the branch 15 provides a positive and the branch 16 a negative phase-correction, the settings of the potentiometers 21, 25 determining the distribution of the correction between the positive and negative excursions of the signal. The setting of the potentiometer 18 and the gain of amplifier 12 determine the magnitude of the correction. In modifications of this circuit (Figs. 2, 6, not shown), the network 13 is inserted in the path comprising branches 15, 16 either at the input or output end of this path. The unbalanced circuit of Fig. 3 employs two amplifiers 29, 30 connected in the main transmission path. Each has a phase-shift of 180 degrees at the mid-band frequency. Network 33 has a phase-shift of 90 degrees and may be connected in either transmission path. The magnitude of the correction is determined by the setting of potentiometers 38, 39 and the gain of amplifiers 29, 30. Potentiometers 40, 41 determine the distribution of the correction between positive and negative excursions of the signal. The unbalanced circuit of Fig. 4 provides only positive phase correction and employs an adjustable attenuator 47 and a 90 degree phaseshifting network 42 connected in the main transmission path. In a modification of this circuit (Fig. 5, not shown), the attenuator is replaced by an amplifier connected in the control path 44. The non-linear devices may be rectifiers of various kinds or non-linear resistors, capacitors or inductors. Specification 847,849 is referred to.

Title: Pellet bed chlorinator and pellet bed chlorination process
IPC: B01J10/00
Filed: 1960-11-11
Abstract: <PICT:0971458/C1/1> Metal halides are prepared by forming a bed of pellets consisting of a mixture of particles of a metal oxide and of carbon in stoichiometric proportions in accordance with the equation MO2+2C+2X2=MX4+2CO where M represents a metal and X represents a halogen, the major proportion by weight of the pellets having a major dimension in the range of 1 mm. to 11 mm., maintaining a reaction zone in the bed at a halogenating temperature, passing a halogenating gas into the reaction zone under substantially static bed conditions, and withdrawing gaseous reaction products upwardly from the reaction zone to effect heat transfer between the reaction products and the pellets in the upper part of the bed.  The reaction is thermally autogeneous. The process is illustrated by reference to the chlorination of hafnium and zirconium but the production of the chlorides of titanium, chromium, aluminium, silicon, niobium, tantalum, beryllium, boron, tin and uranium is also referred to. Elemental chlorine is the preferred source of chlorine although other sources, for example, CCl4, COCl2, S2Cl2 and SOCl2, may be used.  As shown in Fig. 2, chlorine, admitted through line 22, passes upwardly through a cooled lower zone of pellets 38 to a preheated reaction zone 37. The chlorine reacts with the pellets in the reaction zone and the gaseous reaction products pass upwardly through the chlorinator in heat exchange with the pellets in zone 40.  As the pellets in the reaction zone are consumed they are replaced by the preheated pellets in zone 40.
