Title: Improvements in or relating to subscription television system
IPC: H04N7/167
Filed: 1955-09-29
Abstract: 784,108. Television. ZENITH RADIO CORPORATION. Sept. 29, 1955 [Oct. 21, 1954; Dec. 31, 1954], No. 27727/55. Class 40 (3). In subscription television systems in which a coding signal, which operates means to code the video signal at the transmitter and uncode it at the receiver, is transmitted in scrambled form and unscrambled at the receiver, a further signal is derived from the coding apparatus, in both the transmitter and receiver, and applied to effect further modification of the coding. As shown in Fig. 1, a signal from camera 10 is coded in unit 12 by signals from a multivibrator unit 57, 58, 59. The latter is driven by impulses from the synchronizing signal generator 19, which are stepped down in a blocking oscillator 30. Code signal bursts, produced by a generator 29, follow various paths chosen by a multiple switch arrangement 27 to control unit 57, 58, 59. The bursts are also connected through a different pattern of paths to a second multivibrator 57<SP>1</SP>, 58<SP>1</SP>, 59<SP>1</SP>, which operates a gating circuit 46 in a further path from switch bank 27. The further signal mentioned above is thus produced and led to oscillator 30 rendering it ineffective at certain of its normal operating conditions and thus superimposing a further pattern of operation on the coder 12. The receiver shown in Fig. 6 includes a decoding unit 140. The code signal bursts pass along conductor 191 to a gating circuit 159 operated by a unit 160 driven by the field sweep components. Unit 160 also transmits blanking signals via unit 161 to the cathode-ray tube. 141 to ensure complete blanking of the code signal bursts. The unit 159 is connected by a line C to switches 27 and multivibrators 57, 58, 59 and 57<SP>1</SP>, 58<SP>1</SP>, 59<SP>1</SP> similar to those in the transmitter and these are conected to the decoder 140. In modifications the gating circuit 46 may be operated from the output of multivibrator 57, 58, 59, or from the coder 12 itself, multivibrator 57, 58<SP>1</SP>, 59<SP>1</SP> being then omitted. In a further modification the gating circuit 46 is altered to a selector and either diverts a control pulse to the blocking oscillator 30 or turns it into the multivibrator 57, 58, 59.

A keyway 37 on the shaft 13 engages a key which locates in alternative slots 38, 38' in the toothed disc. One slot 38 aligns with a tooth while 38' is displaced by a half pitch, this allows the teeth to be staggered. Several key slots may be provided at fractional pitch displacements. The discs are retained by a nut on a threaded portion of shaft 13. The roller may alternatively be formed from the solid by any suitable method of manufacture.

Title: Improvements to hot water and/or central heating boilers for domestic and like purposes
IPC: F24H9/00
Filed: 1959-08-17
Abstract: 934,957. Hot plate stoves. M. E. NELSON. Aug. 17, 1960 [Aug. 17, 1959], No. 27981/59. Class 126. [Also in Group XIII] In a boiler suitable for use in hot water and central heating systems, water to be heated flows through a flat-sectioned heat-exchange chamber 1 provided with vertical fins 2 via inlet and outlet pipes 4, the chamber with its fins being surrounded by an inner casing 7, open at top and bottom, which is itself surrounded and supported by an outer casing 10 mounted on a suitable base and having a top cover 12. The unfinned side walls of the chamber 1 extend through the casing 7, said walls being thicker than the other walls and being bolted to the outer casing by studs 6. The inner casing 7 extends below the heat-exchanger to surround a space 9 in which a burner (not shown) is mounted. Heated gases rising from the latter pass up through the spaces 8 between the fins and out through a flue pipe 13. Convection currents in the space 11 between the two casings help to keep the outer casing cool and to dilute the combustion products passing out through the flue pipe. The top plate 12 is preferably detachable and has removable rings or plates on which kettles or the like may be placed.

Title: Apparatus for detecting arcs
IPC: B23H1/02
Filed: 1971-06-15
Abstract: 1334600 Spark-erosion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 June 1971 [18 June 1970] 28029/71 Heading B3V [Also in Division H2] The workpiece W and electrode tool E of a spark erosion machine are connected to a "noise" detection circuit, the output terminals of which are connected to a discriminator V which has a reference voltage supply V ref , the discriminator providing an output signal to operate an indicator M and/or a relay (not shown) to interrupt the supply to the machine on the absence of noise due to arcing between the workpieee and tool. The detection circuit may comprise a differentiating network R 1 , C 1 , a rectifying diode D 1  and a load resistor R 2 . The discriminator may be a transistor or an operational amplifier V. To detect the arc, it is necessary to determine that the noise is absent in the presence of current and voltage at the workpiece and electrode, so that a logic circuit L has an input u connected across the workpieee and electrode and an input i connected across a resistor R 3  in series with them. The logic circuit L only ceases to provide a positive output voltage when both current and voltage signals are present. This output voltage is applied to the same input terminal of the amplifier V as that to which the voltage across the resistor R 2  is applied, the amplifier providing an output when the sum of these voltages falls below a given value. To prevent failure to operate due to the summing of pulses in the stray capacitance C 2  of the circuits, a transistor T 1  shortcircuits the resistor R 2  and discharges the capacitance C 2  until the positive signal ceases on each pulse from the pulse generator G supplying the erosion machine. The output pulses from the amplifier V, when arcing occurs, may be counted or integrated, e.g. by a capacitor C 3 , and an amplifying transistor may be provided to operate a relay, Fig. 5 (not shown).

In the construction shown the levers 13, 14 are connected by an adjustable link 17, the lever 14 being connected by a rod 18 to the throttle of the internal-combustion engine (not shown) mounted on the bogie. The shafts of the levers 19, 22 are connected by universal joints 20a, 21a to telescopic shaft parts 20, 21 splined together, the lever 22 being connected by a link 23 to the change-speed gear. The locomotive or coach is provided with a control panel 1a, 1b at each end, these panels having handles 2a, 2b fixed thereto for operating pneumatic clutch valves, and removable handles 24, 25 for operating the change-speed gear and throttle respectively. The handles 24, 25 can be respectively placed on spindles 3a, 3b and 4a, 4b, the spindles 3a, 3b being connected together by the chain system 7, 8 and the spindles 4a, 4b by the system 9, 10. Each chain system comprises short lengths of chain near the spindles and idle pulleys 11, these lengths being connected together by rods 29 provided with adjustable turnbuckles 12. The handles 24, 25 are provided with lugs 24a, 25a which can pass through corresponding slots 27, 28 in the control panels only when the handles are in the zero or neutral position. The handle 24 has a collar on its boss which is adapted to be engaged by a flat sector 31 on the clutch valve handle 2a so that the handle 24 cannot be removed unless the handle 2a is in the clutch released position. A reversing valve spindle 5a has a slot 27 corresponding to the slot for the spindle 3a so that the handle 24 can be used to operate the reversing valve. The lug 25a on the handle 25 is longer than that on the handle 24 so that the handle 25 cannot be used for the reversing valve. Thus before the reversing valve can be operated the handle 25 must be moved from spindle 3a to 5a and therefore the gear must be in neutral and the clutch released.
