Title: Improvements relating to typewriters
Inventor: ROWE ALEXANDER MCDONALD
IPC: B41J11/51
Filed: 1962-11-29
Abstract: 1,044,158. Typewriters etc.; selective printing. PETTY & SONS Ltd. Dec. 2, 1963 [Nov. 29, 1962], No. 45104/62. Heading B6F. An attachment to a typewriter for use in making a condensed record on a copy sheet 13 of, e.g. names of payees and monetary amounts entered on an original 11 such as cheques separated by tear-off lines 12, comprises a pressure member 34 which frictionally holds the copy-sheet in contact with and stationary with the platen 20 whilst the original 11 is being pulled forward by hand to make an entry on the next cheque. The member 34 comprises rubber rollers rotatable about a spindle 35 carried at its ends by arms 33 pivoted about pins 37 eccentrically mounted on discs 30. Springs 38 may be provided to press the arms 33 downwardly. The discs 30 are adjustably secured by screws 31, Fig. 4, to the ends of a bar 22 carried by posts 19 mounted on the carriage 16 by bolt-and-slot connections 27, 28 and 29, 53, Fig. 3 (not shown), which permit adjustment of the posts both parallel to and at right-angles to the platen. Discs 23 on the bar 22 serve as side guides for the original 11, and are notched at their upper edges to accommodate a bar 21 also mounted on the posts 19 and serving to prevent the edges of the original from slipping over the discs. The copy sheet 13, which is divided into sections by perforated lines 15 and is associated with a carbon sheet 14, is laterally guided by the posts 19, passes over the top of the bar 21, between the member 34 and the platen 20, and around the platen where the original 11 is superposed on it, the combined sheets being pressed against the platen by the conventional feed rollers 47. Beyond the printing point 50, the sheets 11, 13 are separated by passing them respectively outside and under the usual paper lock scale 45; to prevent the sheet 11 falling outwardly a bar 42 is attached to the scale 45 so as to be slightly spaced therefrom. In operation, after an entry has been made on a cheque, the platen is linespaced and the rollers 47 moved away from the platen. The original can now be pulled through the machine until the printing line of the next cheque is at the printing position, the pressure member 34 preventing movement of the copy sheet 13 during this operation. This sequence of operations is continued as required. Any pull on the copy sheet tends to increase the frictional grip of the member 34. The levers 33 may be pivoted upwardly and over a deadcentre position when the member 34 is not required.

Title: Frequency-modulated subcarrier detector
IPC: H04H20/88
Filed: 1961-12-19
Abstract: 945,268. Frequency discriminators. HAZELTINE CORPORATION. Dec. 19, 1961 [Jan. 24, 1961], No. 45539/61. Heading H3A. Relates to apparatus for measuring the repetition rate of a repetitive signal which comprises a means for amplitude limiting the repetitive signal, a differentiating means including an inductor for developing from the limited signal a series of pulses which in comparison to differentiated pulses developed in the absence of the inductor have a faster terminal decay than such pulses and means for rectifying the said pulses developed by the differentiating means so as to retain a series of same polarity pulses whose average value is representative of the repetition rate of the repetitive signal. The invention is particularly described with reference to detecting the modulation of a frequency modulated subcarrier of a frequency modulated multiplex signal, wherein the subcarrier is used as one of the modulating signals of a main carrier. Such a technique may be used to provide background music to normal programme material, or in stereo broadcasting. The main carrier is received in a unit 10, where the main modulating signal is detected and reproduced at 12 while the detected subcarrier is fed via a buffer amplifier 13 and a filter 14 to an amplifier 15 and a limiter 16, after which the subcarrier is fed to a detector 17. The detector comprises in addition to the conventional differentiating components 22, 23 an inductor 21, which speeds the recovery period of the differentiated wave (see curve B of Fig. 2a). A diode 24 rectifies the differentiated pulses, which are then passed to an integrator 26, 27, arranged to produce an output voltage depending upon the repetition rate of the input pulses. This signal is fed to an amplifier 18 and thence to an output reproduction stage 19. The arrangement is said to minimize the degradation in linearity which occurs in a conventional detector due to the failure of the differentiated pulses to return to zero before the following pulse occurs.
