Abstract: 1475176 D.C.-D.C. converters PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 July 1974 [23 July 1973] 32117/74 Heading H2F [Also in Division H3] The invention relates to a line time base of the type in which deflection coils Ly are associated with a trace capacitor Ct, a retrace capacitor Cr, a diode D 1  passing deflection current during one part of the sweep and a switch Tr and a diode in series therewith passing deflection current dur. ing another part, a storage inductor T 1  being charged while the switch Tr is conductive and then discharged into the deflection circuit to restore lines. According to the invention the discharge energy is passed to the deflection circuit via a diode D 3  and a transformer L 3  connected to the deflection circuit via a capacitor C 1 . This arrangement reduces the voltage applied to Tr during the fly-back. Diode D 3  could alternatively be connected to a separate secondary winding of L 3  and L 3  may be a winding of T 1 . C 3  and capacitors connected across the two parts of L 3  (Fig. 4, not shown) prevent ringing. Ct may provide S connection. L 4  supplies a rectifier providing a D.C. supply, e.g. for the CR tube and stabilization of the circuit may be effected by controlling the "on" time of the transistor.

Title: Gamma-Correction Arrangement
IPC: H04N5/202
Filed: 1967-07-13
Abstract: 1,191,886. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 July, 1967 [16 July, 1966], No. 32219/67. Heading H4F. [Also in Division G4] A gamma-correction circuit arranged to provide a variable correction characteristic the various inclinations of which can be individually adjusted without influencing each other, whilst the black and the white level remain at constant values, comprises three current sources, i.e. transistors 12, 13, 14, Fig. 1, controlled by the signal to be corrected. With the signal to be corrected representing the black level and the grey varying linearly to the white level, Fig. 2a, applied to input terminal 1, transistor 12 produces across resistor 35, i.e. at output terminal 36, a voltage corresponding to a current varying throughout the signal range of the correction characteristic, Fig. 2c, the amplitude of which may be adjusted by means of resistor 27, transistor 13 produces a current varying through a first part of the signal range from a value fixed at the black level by a clamp circuit including transistor 9 to a second fixed value determined by adjustable resistor 28, Fig. 2d, and transistor 14 produces a current varying through a second part of the signal range from a third fixed value determined by adjustable resistor 29 to a value fixed at the white level by a clamp circuit including transistor 10, Fig. 2e. Line-scanning clamp pulses are applied to the bases of transistors 9 and 10 through blocking capacitors 15 and 16, the signal to be corrected being inverted by phase inverter 4 before being applied to the collector of transistor 10. The circuit is so arranged that the first and second part of the signal range of the correction characteristic do not overlap and that the currents in these parts vary in opposite senses. The three current sources are interconnected so that the corrected signal produced comprises a superimposition voltage at output 36, Fig. 2f. As shown in Fig. 1, a fourth current source, transistor 11, transfers the signal to be corrected in the non- corrected state and a selection switch 30 passes to output 36 either current from the three transistors 12, 13 and 14 or current from transistor 11. Switch 30 provides the possibility of comparing the signal range between the black and white levels of the unvaried signal with the signal range of the gamma-corrected signal so that a calibration may be obtained by means of variable resistor 27. Variable resistor 34 in the emitter circuit of transistor 31 comprises a peak white limiter. In the clamp circuits, diode 20 and Zener diode 24 are included for temperature stabilization in the direct-voltage emitter circuit. An additional current source may be provided, operative over a further part of the signal range which is adjacent to and overlapping one of the other parts, i.e. the first or second part, of the signal range, the overlapping portion being influenced by the two signal sources for the adjacent parts.

Title: Improvements in cigar enveloping machine
IPC: B65B19/26
Filed: 1927-12-02
Abstract: 310,982. Marks, E. C. R., (International Cigar Machinery Co.). Dec. 2, 1927. Packeting by wrapping-up.-In a machine for wrapping cigars, the cigars 54, Fig. 1, are placed on a feed table 55, and are advanced by pins 60- on conveyer chains 57 into contact with a finger- 71 which controls each forward step of the conveyer. A lifting member 74 pivoted at 31, raises ,the foremost cigar through a curved guide 75 and delivers it, with a wrapper, into a pocket in a rotary turret mounted on a shaft 26. The wrapping material 81 is fed from a reel 89, controlled by a strap 92 and weight 91, passes between feed rollers 82, 83, and is severed into wrappers by a knife 88. The receiving pockets comprise stationary sides 85, movable spring pressed sides 86, and yielding bases 87. A folder 121 turns up the depending edge of the wrapper, and, during the first intermittent movement of the turret, the upper edge 120 is turned down by a stationary folder 126, so that the wrapper is disposed about the cigar as a substantially cylindrical tube with projecting ends. On arrival at the folding station at the top of the turret, the projecting ends are subjected to the actions of dies 127, 128, Figs. 1, 4, and 5, causing channel folds 129, Fig. 10, to be formed. The dies, which are'mounted on arms 130, 131, swing into the open position shown in Fig. 1, and split cups 50, Fig. 11, close axially upon the end folds. The cups are so shaped that, during the engaging movement, one upstanding fold 129 at each end of the cigar is folded down and the other enters an axial slot 140. While the cigar is still held stationary, the cups are turned through one revolution to turn down the flaps in the slots 140. Tuckers 141, Fig. 13, are now pressed down through transverse slots 142 in the cups and form folds in the end flaps of the wrapper. Hangers 51 move inwards axially as shown in Fig. 15, and turn up the extreme ends of the wrapper, and the cups 50 are given another revolution, faces 143 thereon smoothing out the folds and completing the wrapping to form a package as shown in Fig. 16. The turret now advances to a discharging station, at which the movable side 86 is opened and releases the yielding base 87 so that it pushes the wrapped cigar 164 into a carrier 165, which turns downwards and deposits the cigar on a delivery table 172, along which they are advanced by a. finger 178.
