Filed: 1928-12-11
Abstract: 326,453. Readman, H. Dec. 11, 1928. Spinning tackle. - An eccentrically mounted spinner which imparts a wriggling motion to a bait comprises a propeller which may have one blade larger than the other and is carried in front of the bait on the end of a crank 7. The device is attached to the line and to the bait by swivels 10, 11 and to prevent rotation of the bait a weight 14, is inserted in or may form its body. The bait which may be of ichthyoid form and have a thin flexible tail, may be made of rubber. The hooks may be attached directly to the weight 14 or may he attached by a cord passing through a channel 17. With an artificial fly as bait the weight 14 may form the body to which the wings and hook are bound. With natural bait, such as a minnow, the weight 14 may be thrust along its breast and the hook bound to its body, while with prawn bait a spike is pushed through the tail of the prawn and the end engaged with the fish hook.

Abstract: 891,530. Colour television. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 18, 1958 [Nov. 20, 1957], No. 37071/58. Class 40(3). The invention relates to a receiver for use with the N.T.S.C. type of signal in which demodulation is effected along the R-Y and B-Y axes, and is concerned with correcting for the effect of the single sideband transmission of the I signal over the band 500- 1500 kc. which, in such a receiver, results in the 500-1500 kc. components of the I signal appearing in the R-Y and B-Y channels with incorrect amplitude and phase. In accordance with the invention, the outputs from the R-Y and B-Y demodulators 1 and 2, Fig. 2, which are preferably high-level demodulators, are applied through correcting networks 3 and 4 with appropriate amplitude and phase characteristics, Fig. 4, to bring the 500-1500 kc. portions of the signals in the correct relationship with the 0-500 kc. portions. A G-Y signal is produced in a conventional manner by combination of - (R-Y) and - (B-Y) signals from the demodulators, the signals either being passed through separate correcting networks 8 and 9 or combined first and passed through a common correcting network. The accompanying luminance signal passes through a delay network 10.

A galvanic cell for use in the determination of the oxygen content of a gas or vapour comprises a cathode 4 of metal chips or wool, e.g. of silver, copper or titanium, covered with a film of electrolyte and contained in a cylindrical porous diaphragm 3, e.g. of P.V.C., soaked in the electrolyte. This diaphragm also separates the cathode from a cylindrical nickel-cadmium anode 2. A further electrode 6, separated from the anode by a porous P.V.C. diaphragm 5, soaked in the electrolyte, serves as a charging electrode.

A lead 12 in the cathode provides connection between it and the cathode terminal 11. Before operation the cell is filled with the electrolyte, e.g. caustic soda or potash solution or aqueous sulphuric acid, most of which is then emptied out leaving the porous diaphragms soaked in it and a film of it on the cathode.

[Also in Division F4] The axial flow annular metallic matrix 10, Fig. 4, of a rotary regenerator is driven by and radially located on a drive shaft 31 by a sixsided coupling member or spider 34 non- rotatably mounted on the shaft by splines 35 and formed with three bosses 38, each supporting a roller 39 on a shaft 41 adapted to roll or slide axially of the matrix within tracks 47 formed in a coupling member or hub 46 secured by bolts 45 to a hub 18 of the matrix. Inclination of the matrix relative to the drive shaft is accommodated by relative motion of the rollers 39 in the tracks 47 and the rollers also centre the matrix with respect to the shaft while expansion of the hub 46 relative to the spider 34 is permitted by radial sliding of the rollers in the tracks. In a modification, a ceramic matrix 71, Fig. 6, is coupled to the drive shaft to accommodate axial movement, expansion of the coupling and misalignment of the hub relative to the drive shaft and also to centre the matrix relative to the shaft.

Filed: 1969-07-29
Abstract: 1,224,574. Selective signalling. DIGITRONICS CORP. 29 July, 1969, No. 38088/69. Heading G4H. A business, e.g. adding, machine having character and function keys is associated with a system for recording signals representing the characters entered and the functions performed in response to operation of the keys, and to ensure correct recording even in the event of incorrect key operation, a signal generator is connected to key-operated switches to produce corresponding signals for recording only when a key has been fully operated, and the generator removes its output in response to an acknowledgement signal from the recording system when the character signals have been recorded. As a key is depressed, it first actuates a mechanical interlock and sequentially opens and closes magnetic reed switches 110, 80 respectively, switch 80 only being closed when the machine is mechanically committed, i.e. when the operated key has set a mechanical memory element on a carriage and the carriage has been advanced to a position intermediate two successive character-storing positions. Closure of switch 80 connects the output of transistor 28 to switches 114 which are selectively operated by the character keys, and in response to the output on leads 118, the recording system produces and stores character code signals. The transistor bi-stable circuit is set over lead 93 in response to the acknowledgement signal to remove the output from transistor 82. The bi-stable cannot be reset until switch 110 has closed, which occurs when the key has been released and has passed beyond the point at which the carriage has completed its step to the next character-storing position, so that multiple machine entry and recording by a "dithering" keystroke is avoided. Signals representing the functions performed by the machine are generated by switches associated with the function keys, the signals only being produced on closure of a switch by a cam when the machine has been committed to the performance of the selected function.
