Title: Consistency measuring apparatus
Inventor: SAMSON JOSEPH EPHRAIM
IPC: G01N11/10
Filed: 1964-11-10
Abstract: 1060459 Measuring consistency of materials FISCHER & PORTER Ltd 10 Nov 1964 45832/64 Addition to 1056161 Headings D2A and A8B Consistency measuring apparatus as claimed in the parent Specification but modified in that the cantilever element directly actuates or is formed by the lever 26 of a pneumatic or electrical transducer, the lever 26 passing through and being sealed to the wall of the conduit and producing a charge in a pneumatic or electronic amplifier outside the conduit to provide an output signal which as well as constituting a measure of consistency, controls means to apply a restoring force to the lever and thus to the cantilever element, so that the transducer functions as a null-balance device. The lever 26 extends through the cantilever element 21, mounted by a collar 15 in an aperture of a conduit 11, into a damping chamber 24 filled with oil. A disc 28 is attached to the lever 26 to facilitate damping. Within a casing 25, the lever 26 carries a flap (not shown) located in front of an air nozzle, so that the resultant back pressure varies according to the position of lever 26. The resultant signal is  fed through an amplifier to a bellows which urges the lever 26 to the undepicted position. Alternatively, the pneumatic system may be replaced by an electro-mechanical transducer system.

Title: Pulse signal handling circuit arrangements
IPC: G01S13/78
Filed: 1972-10-05
Abstract: 1386183 Selective signalling ELLIOTT BROS (LONDON) Ltd 13 Sept 1973 [5 Oct 1972] 45920/72 Heading G4H [Also in Division H4] In a circuit arrangement for use in a transponder system for recognizing two or more pulses in a series by their mutual separation(s) and indicating the time of arrival of one of the pulses in the series in relation to a transmitted interrogation pulse, one of the pulses starts a first counter counting fast clock pulses, the count being frozen and transferred into a store (e.g. multiple shift register) at a known predetermined reference instant in time defined by slow clock pulses to indicate the time of arrival, a recognition shift register being shifted by the slow clock pulses and receiving signals derived from the pulses in the said series, gating means responsive to coincidence of pulses in two or more suitably-spaced stages of this shift register recognizing the said two or more pulses as having the required separation(s), a second counter counting the slow clock pulses between the transmission of the interrogation pulse and the appearance of an output from the gating means. The slow clock pulses also shift the multiple shift register and are generated under control of the fast clock pulses applied through a frequency-divider. Any of a plurality of stages of the recognition shift register may be selected to participate in the said coincidence detection, by control signals applied to AND gates, thus permitting a pulse separation to be recognized to be preselected. Pulse jitter can be allowed for by ORing several adjacent stages prior to the coincidence detection or by using a further shift register into which a sequence of puses is set in response to a single pulse. Other multiple shift registers may store the pulse amplitudes etc. The circuit arrangement is used in an interrogator/transponder in airborne distance measuring equipment, the series of pulses coming from a ground station in response to an interrogation, the separation(s) indicating which such interrogator/transponder the signal is intended for, and the time of arrival indicating the distance.

Title: Improvements in or relating to data transmission systems
IPC: H04L27/02
Filed: 1963-11-21
Abstract: 1,036,316. Data transmission; radio signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1963 [Dec. 18, 1962], No. 45924/63. Headings H4L and H4P. In a vestigial side-band data transmission system single frequency control signals are added to the transmitted signal, the receiver including means to derive from the added signals the correct phase of retrieved carrier. Means is also provided at the receiver for establishing the correct threshold in the detector-the system operating on multilevel signals-and to generate clock signals. Prior to transmission of data, carrier is generated which pulls the output toggle of the receiver carrier retrieval circuit to the correct phase. The retrieval circuit, Fig. 2 (not shown), is fed with the received signal and with the output of the demodulator. The output of filter 30 is at twice carrier frequency and inherently reverses phase when the modulation changes polarity. This is fed to carrier threshold detector 37 to enable AND gate 36. This gate provides an output which controls the phase of toggle 33 so that its output, at carrier frequency, is in the correct phase. The system described uses a multi-level signal, and since variation of attenuation in the line could cause errors the threshold levels in the receiver detector are varied correspondingly. The control is derived either by transmitting a continuous signal which has a frequency above the V.S.B. spectrum, variation in this signal level being used to control the threshold levels in the detector, or by using the attenuation of the carrier signal transmitted prior to data (referred to above). In this latter instance a servo loop sets the threshold levels during the reception of that signal. Clock signals introduced at a point following the V.S.B. filter at the transmitter are reconstituted at the receiver for use in the multilevel to binary code converter. Alternatively the clock is derived from the data transitions as described in Specification 1,031,596.

To bring a thread into operation member 4 is rotated and the corresponding cam N is brought into position beside the guide Fa so that the thread extends radially and is taken by the needles. The thread previously being knitted is held in slot 3a and severed, the cam N returning with member 4 to its normal position.
