Title: Process and apparatus for high frequency telephony with or without wires
IPC: H03C1/10
Filed: 1921-12-03
Abstract: 194,362. Jones, H. Sefton-, (Lorenz Akt.- Ges., C.). Dec. 3, 1921. Madulating systems and apparatus.-Relates to wireless or line high-frequency transmitting systems comprising a thermionic amplifier g controlled by a microphone k, the normal plate current from the amplifier being utilized to mag. netize an iron core f which acts as a modulator. The invention consists in means for adjusting the magnetic flux of the iron core to the most favourable working value. In one form, this is effected independently of the normal or " no load " plate current of the amplifier, an auxiliary winding e fed from a separate battery through an adjustable resistance, being used to augment the flux due to the normal or " no load " plate current flowing through the winding d from the amplifier g. Instead of using a separate winding e, the auxiliary magnetizing-current may be fed through choke-coils direct to the high-frequency winding. In another form the plate current itself may be raised to increase the flux to the desired optimum value by imposing an adjustable positive voltage on the grid of the amplifier.

Title: A numbering mechanism for printing of numbers in letter form
IPC: B41K3/10
Filed: 1969-06-27
Abstract: 1,268,495. Number printing mechanism; selective printing. ESSELTE A.B. 27 June, 1969 [27 June, 1968], No. 32601/69. Headings B6C and B6F. A numbering mechanism for printing of serial numbers in word form comprises a plurality of number wheels 3, each with numerals expressed in words at its periphery, including a "units" wheel on which the numerals "one" to "nine" are interspersed with the numerals "ten" to "nineteen" and a "tens" wheel bearing the numerals from "twenty" to "ninety". Blank spaces, preferably filled with patterns to prevent counterfeiting, and joining words such as "and", appropriate to the language printed, make it possible to express any numeral. In a Swedish embodiment the counters are advanced by ratchet action of members 4a-4e, integral with plate 5, which is pivotally mounted on rocking member 6 and is spring-biased. The members 4a-4e are of differing lengths, and co-operate with notched gears 7, 8, 9 on the wheels 3 according to the distance of plate 5 from shaft 2. As each gear 7, 8, 9 rotates a deeper than normal notch encounters the co-operating member 4a- 4e once in each revolution so that the nexthighest wheel 3 is advanced by one position. The stroke of the rocking member is such that the tens and higher wheels 3 are advanced by one position each time they are advanced, and the units wheel by two positions. When member 4a encounters notch 11 after printing "nine" member 46 encounters tooth 12, so that a threespace movement to print "ten" is made and the "tens" wheel is not advanced. After printing of "nineteen", however, only a single-space movement of the "units" wheel takes place and the "tens" wheel is advanced to print "twenty". Multiply-advanced "tens" and higher wheels may similarly be employed when required by the language printed.

Title: Improvements in or relating to sound film systems and apparatus
IPC: G11B7/00
Filed: 1934-11-19
Abstract: 449,079. Optical sound-reproducing and re-recording processes. ROUND, H. J., Westfield, Muswell Hill, London. Nov. 19, 1934, Nos. 33272/34 and 3888/35. [Class 40 (ii)] Relates to a sound film play-off system for reducing ground noise in reproducing or rerecording sound from a sound film recorded by the variable area method. According to the invention, playing off is effected by forming on the film a slit-like image of light of substantially constant light quantity per unit length, the image being substantially narrower and of equivalently higher light intensity over the length thereof corresponding to the recorded portion of the film than over the rest of its length. Fig. 2 shows one method of carrying the invention into effect in which light from a source (not shown), is projected through the usual apertured diaphragm member D and lens system PL on to a film F, a small additional cylindrical lens CL carried by the armature A of a relay system RS being moved more or less into the light path in accordance with the envelope of the recorded sound. The system RS is preferably fed with rectified and smoothed currents derived from the record itself either at the reproducing point or at a point somewhat ahead thereof. According to a modification, the lens CL may be replaced by a sheet of transparent material, such as glass. Fig. 3 shows a further modification in which the member M carries a diaphragm member having a slot of two different widths over two different portions of its length, the slot being masked over its wider portion by a piece of film &c. 'whose transparency is such that the amount of light passed through by the widened length of slot is substantially the same as that which would have been passed by the same length of slot had it been unmasked and of the same width as the narrower length. Light from a source X passes through the condenser lens system CLS and diaphragm member and is projected by the oscillograph mirror OM operated by rectified speech currents on to the film F. Instead of employing an oscillograph mirror, the member M may itself be moved in accordance with the rectified signals.
