Title: Method and device fordriving liquid crystal display matrix
IPC: G09G3/18
Filed: 1976-11-17
Abstract: A method of driving a liquid crystal display matrix, in which digit drive signals are applied to digit electrodes and segment drive signals are applied to segment electrodes. Each of the digit drive signals has first pulse components of a first pulse width varying at a plurality of voltage potentials in a first predetermined sequence during each cycle, and a second pulse component of a second pulse width having a selected one of the voltage potentials during each half cycle. Each of the segment drive signals has first pulse components of the first pulse width varying at at least two of the voltage potentials in a second predetermined sequence, and a second pulse component of the second pulse width having a voltage potential equal to that of the second pulse component of the digit drive signal. The second pulse components of the digit and segment drive signals are in synchronism with each other, whereby the potential difference across the electrodes will be zero to reduce the root-mean-square voltage applied to the liquid crystal display matrix. The duty cycles of the digit drive signals and the segment drive signals are varied in dependence on an ambient temperature.

Title: Facsimile receiver
IPC: H03L7/08
Filed: 1975-11-20
Abstract: 1512226 AFC systems XEROX CORP 20 Nov 1975 47891/75 Heading H3A A facsimile receiver for receiving carrier suppressed amplitude modulated incoming signals comprises a demodulator 17 and a phase lock circuit including a phase comparator 32, an oscillator 33 controlled by the error signal of 32 for deriving demodulating signals for 17 and a circuit 37 responsive to the incoming signals to restrict the application of the error signal to periods where there is a reliable carrier signal present. If the carrier drift due to variations in transmission lines or individual carrier generators is appreciable or if the carrier appears at instants of large noise, the oscillator may lock incorrectly to a lower sideband or a line transient. The circuit 37 prevents the application of the error signal, if the period of incoming signals (including carrier signals) is more than a predetermined period. Although spurious high frequency signals could be arranged to be eliminated by 37, they are in fact eliminated by the transmission line and line filters. Fig. 1 (not shown) relates to a facsimile receiver arrangement.

Title: System for processing synchronous digital information signals
IPC: H04L7/00
Filed: 1965-11-12
Abstract: 1,122,195. Data transmission systems. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 12 Nov., 1965 [13 Nov., 1964], No. 48258/65. Heading H4P. In a system for deriving a synchronizing signal from data accompanied by noise, means is provided for extrapolating the sync. signal derived in a relatively noise-free period to a previously occurring noisy period. The received data is recorded on one track of a magnetic tape. On a second track the actual time is recorded in m.sec. intervals. From this track a counter derives a number representing minutes, second and m.sec. From the recorded data a computing arrangement determines the time instant t 0  of the first sync. pulse of a series of sync. pulses derived during a noisefree period and the average time interval separating adjacent sync. pulses. It also determines an earlier instant t 8  at which, it is calculated, a sync. pulse should have occurred: t 8  is during a period of high noise level. The recorded data is then read again, and when the recorded time track indicates the same value as the calculated t 8  a pulse is recorded on a third track, this acting as a sync. pulse track. To the calculated value t 8  is now added a value approximately equal to the time difference between the first two sync. pulses, i.e. t 1 -t 0  (the method of determining this value is detailed in the Specification), and when this sum equals the recorded time a further pulse is recorded on the sync. track. This process continues until all the sync. pulses up to the first sync. pulse, at t 0  have been inserted on the sync. track, whereafter the sync. pulses derived from the data in known manner are recorded. The data on the first track is subsequently synchronously demodulated using the pulses on the sync. track.

Filed: 1975-12-03
Abstract: 1519799 Sensing movement &c CARBA SA 3 Dec 1975 [5 Dec 1974] 49673/75 Heading G1A In a device for sensing deliberate movement of a limb &c. of an invalid which may tremble or otherwise move involuntarily, the invalid may use his limb to interrupt or reflect radiation from a source to be received by a detector. The output of the detector is passed via a delay element to a switching device. The delay element is included to mitigate the effect of small involuntary movement. Light, infrared, or ultrasonic radiation may be used. In Fig. 1, infrared radiation from a source 5, connected to a power supply 6, passes via a lens 7 to form a beam path 8 which may be interrupted by the invalid. The resulting radiation is received by a photo-electric cell 11 positioned behind a lens 10. The photo-electric cell's output is fed via an amplifier 4 and a delay device to a relay 1 comprising a coil 3 and a contact set 2. A modification of the beam interruption system is described Fig. 2 (not shown) whereby the source and detector are side by side. The radiation beam from the source is reflected by a reflector (11) back on to the detector. Alternatively Fig. 3 (not shown) the invalid's hand &c. may itself by used as the reflector. The description also refers to an ultrasonic radiation system utilizing the Doppler Effect wherein a control signal is obtained from the patient's movement in the beam rather than from its presence in the beam.

Abstract: 1286665 Flaw detection BARRY-WEHMILLER CO 13 Oct 1969 [6 Nov 1968] 50236/69 Heading G1A An apparatus for detecting flaws in container crown rings comprises means to locate the containers for inspection, a housing containing a  plurality of lamps and corresponding blocking pins surrounding a position in the path of the container crown ring whereby the light beam from each said lamp is effective to illuminate portions of the crown ring at either side of the blocked beampath, light sensing means; and scanning means between said light sensing means and the crown ring to be inspected, said scanning means operating to expose sucessive sectors of the crown ring to said light sensing means, whereby the crown ring is inspected for light deflecting flaws. In one embodiment, Fig.1, the containers C, are moved on a conveyer 10 through a circular illumination unit 40 where the crown rings CR are illuminated by a number of circumferentially spaced lamps 42, arranged behind shields 43 and blocking pins 43a such that no light is reflected vertically upwards unless there is a flaw present. Light deflected upwards passes through a collimating lens 32, a rotating dove prism 27, and a second collimating lens 36 to be projected on to a mask 38 having an aperture 39, which allows light from sucessive sections of the crown ring to pass through to a photo-multiplier tube 37, thereby scanning the crown ring for any light deflected by flaws. A photo-cell 47 receives light from a lamp 51 after it has passed through one of several circumferentially spaced apertures 49 in star wheel 14, said lamp being positioned such that the photo-cell will generate a signal only when star wheels 13 and 14 have positioned a container within the illumination unit 40 and beneath the photo-multiplier 37. An associated electric circuit includes a coincidence gate which receives signals derived from the photo-multiplier 37 and the photo-cell 47. When both signals are simultaneously received a reject signal is generated to operate a reject solenoid (64), Fig.9A (not shown) which is part of a suction system associated with suction cups 18. A similar embodiment is described, Fig.7 (not shown), in which prism 27 is replaced by a rotary tube having a mask (38) with a slit (39a) therein.
