Title: Improvements in electric indicators and counters
IPC: H04M3/64
Filed: 1945-05-31
Abstract: 598,974. Counting-apparatus. DAVEY, W. C. May 31, 1945, No. 13700. [Class 106 (i)] [Also in Group XXXVIII] An electric counter comprises a plurality of digit selectors each operated by a step-by-step switch actuated electromagnetically and each having a plate bearing miniature numbers attached to the moving part of the switch and an optical projector arranged to throw an enlarged image of one number upon a screen. Each time an impulse is sent to an electromagnet 3, a pawl 5 engages a notched stem 1 carrying digits 13 and so brings the digits 0 to 9 successiv ly into position in an optical system comprising a diaphragm, lens, lamp and screen. The stem 1 is prevented from falling, when the circuit of the electromagnet 3 is broken, by a detent 7 controlled by a release magnet 8. When the stem is lifted, it allows a contact 9 to close. 'Fig. 5 shows the electric circuit for a counter comprising units', tens' and hundreds' digit selectors. A contact 30 is closed and an impulse sent to the electromagnet 3 of the units' digit selector for each unit to be counted. The tenth impulse lifts the stem momentarily and closes contact 31 to send an impulse to the electromagnet 3 of the tens' digit selector, while also completing a circuit through the units release magnet 8 and contact 9, thus setting up a digit on the tens' indicator while returning the units indicator to zero. Similarly, the hundredth impulse causes a unit to be set up on the hundreds indicator while zeroizing the tens and units. The digits may be reduced photographically from large models and formed inverted in a single column on a narrow strip of film or glass 13.

Abstract: 751,541. Radio direction-finding. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 17, 1954 [May 16, 1953], No. 14485/54. Class 40 (7). In a system for determining the direction of a received signal, e.g. a reflected radar signal or a signal from a remote transmitter, a directional receiving antenna having a directive pattern, such as that shown in Fig. 1, is rotated about a point at constant speed and the received signal differentiated to obtain a wave as shown in Fig. 2. A circuit effectively responsive to the minimum value is then arranged to reverse the direction of rotation whereby the antenna oscillates between the angles - α<SP>1</SP> and + α<SP>1</SP> and indicates the direction of the received signal by the bisectrix of the swept angle. In the particular embodiment, Fig. 3 (not shown), the received signal is a modulated U.H.F. wave, the modulation component of which is detected by a negatively-connected diode detector having a CR load arranged to produce the derivative of the detector output. This output is then applied to a pentode arranged to respond to the maximum value of the derived signal and having in its anode circuit a relay controlling the reversal of a motor rotating the receiving antenna.

Title: Improvements in carding machine attachment for controlling the web weight
IPC: D01G23/06
Filed: 1946-05-15
Abstract: 615,926. Automatic control systems for carding - machines. UNITED STATES RUBBER CO. May 15, 1946, No. 14651. Convention date, July 20, 1945. [Class 38 (iv)] [Also in Group XXXVII] The average thickness of a fibre web leaving a carding machine is controlled by scanning the web by high-frequency air waves and removing varying amounts of the fibre in accordance with the control imparted by the scanning mechanism. An over-thick web 19 is removed from a doffer cylinder 14 by a main doffer comb 20 and is passed between rollers 28, 29 to a coiling bin (not shown). The web passes between guides 47, 47<SP>1</SP>, where it is scanned by supersonic air waves sent out from a crystal transmitter 43, Fig. 5. The voltages generated by these waves in a crystal receiver 44 vary in proportion to the thickness of the web and are applied to rectifiers 50, 51 which supply a rectified signal to the grids of valves 52 and 53. When no signal is received, valve 52 is arranged to be biassed to twice plate current cut-off, and valve 53 has a minimum bias to permit maximum plate current. When the sound absorption by the web is at a minimum, i.e. when the web is thin, valve 52 conducts and valve 53 is blocked, and vice versa. When 52 conducts, the D.C. coil 67 of a saturable reactor 61 is energized, so as to reduce the A.C. impedance of coils 63, 64 in series with the field winding 69 of the motor 70 which, through gearing 35, 41, controls the extent of movement in one direction of an auxiliary comb 32 for removing fibres from the web 19. The motor is reversed when the valve 53 conducts, i.e. when the web is too thick and when reactor 62 is active. The auxiliary comb 32 is moved to the left or right, Fig. 3, by the motor 70 to remove a greater or lesser amount of fibre in accordance with the signal voltage generated in receiver 44. The fibres may alternatively be removed by a vacuum nozzle (Fig. 6, not shown).
