Title: Improvements in or relating to advertisement devices
IPC: G09F19/08
Filed: 1930-04-11
Abstract: 348,830. Leaf turners. BINGER, O. D., 15, Cecil Court, St. Martin's Lane, London. April 11, 1930, No. 11523. [Class 52 (iii).] A book or like device has its leaves turned by an automaton which with one limb or member raises a leaf and with another member turns it partly over. In one form a suction cup 7 is mounted on the hand 8 or on a rod 6 of an automaton 5 standing on a base 1 containing the operating mechanism. The suction is produced by a pump 11 driven. through reduction gearing by a motor 9 and connected through an equalizing chamber 12 and a valve 13 to the cup 7. The valve 13 comprises two superposed discs, perforations in which can be brought into or out of register by rotating one of the discs by a cam 16 mounted on a shaft 15 driven by the motor 9, and serves to close the connecting tube 14 or to open it to the atmosphere and so break the suction. Other cams 17-20 on the shaft 15 act through levers 21 and wires 22 to raise the hand 8 with the attached leaf, to insert a rod 27 in the hand 25 beneath the leaf and to turn it further over till it drops by gravity, and to bring the cup 7 down on the next leaf. When all the leaves have been turned a pin 31 under the first leaf is rotated, to replace the leaves at their starting position, by a cam 34 driven by reduction gearing from the shaft 15. The pin 31 is returned by a spring, by gravity, or by the pressure of the first leaf in turning. Additional cams and levers may be provided for actuating the mouth or other parts of the automaton.

IPC: B63H23/24
Filed: 1921-04-22
Abstract: 174,315. Soc. Anon. des Forges et Chantiers de la MÚditerranÚe, and Cacaud, M. J. B. Jan. 21, 1921, [Convention date]. Driving - arrangements. -Plant for ship propulsion comprises turbines geared to the propeller shaft for high-speed propulsion and electromotors coupled to the forward end of the turbine shaft for cruising speeds and reversing, at which times the turbines are idly revolved. The generator set for the electromotor may be that used for driving the auxiliary machinery of the main turbines or a separate generator may be provided. The turbine of the generator set may have reversing blades, or reversal is obtained by controls in the electrical portion of the plant. A separate plant is provided for the port and starboard installations. Turbines A drive shafts C through gearing B, and electromotors D are directly coupled to the turbines. Auxiliary turbines drive the electricgenerator groups E, and supply the motors D forcruising, whilst at high speeds they supply powerfor the auxiliaries of the main turbines. When changing from cruising to full speed, the main turbines are started, and as they pick up, themotors D are brought into synchronism and theirpower will diminish, thereby permitting the generators to be switched on to the auxiliaries and allowing the motors to be cut out. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement wherein the electromotors are geared to the turbine gears. This subject-matter does not appear in the Specification as accepted.

Abstract: 1518558 A/D and D/A converters GENERAL INSTRUMENT MICROELECTRONICS Ltd 18 March 1977 [24 March 1976] 11926/76 Heading H3H For A-to-D conversion, one of two capacitances Cl, C2 is charged by the analogue input I, the capacitance being selected according to the polarity of the input as determined by a comparator K, then the other capacitance is charged until a predetermined relationship between the voltages on the two capacitances is detected by the comparator, the time required for the latter charging being digitized. The latter charging is done from a constant-current source I1 or I2 according to the capacitor being charged, these sources having opposite polarities. The time is digitized by counting up a counter 7. For D-to-A conversion, the counter 7 is preset with the digital input, apart from the sign bit which selects one of the capacitors C1, C2 which is then charged from the respective source I1, I2 as the counter is counted down to zero at which the analogue output is gated from an operational amplifier K1 fed from the capacitors.

Abstract: 839,481. Frequency measurement; wavemeters. RUSSELL, F. M. April 18, 1958 [April 12, 1957], No. 12035/57. Class 37. In a high-frequency wavemeter, the signals are fed to a variable-length transmission line 2, 4 adjustable to resonance in accordance with an indication from resonance detection means connected to the input end of the line; the input signal frequency, as determined by the adjusted position of the line, being shown by an indicator. Conductive strips 4, 2 are spirally wound; the two sides of the strip 2 respectively constituting an outer conductor for two adjacent turns of the transmission line; the strip 2 being mounted edgewise on a circular metal base 1, and the strip 4 being mounted edgewise on spaced insulators 3. A circular metal carrier 7 lies adjacent the upper edge of strip 2, and is rotatable through a reduction drive by control knob 9 thereby causing a shorting member 6, connecting the strips 2, 4 to move along the spiral transmission line. An input signal is fed to one end of the line and the shorting member is moved to a “ wavelength or ¥ wavelength position along the line from the input end, this resonant position being indicated by a meter connected across a bridge rectifier which is fed from a broad-band transistor amplifier connected to the input end of the line, Fig. 4 (not shown), a switch 21 controlling the gain thereof. The position of the shorting strip provides an indication of the input frequency which may be read from a suitably graduated scale attached to the carrier 7.
