Title: Computer peripheral device
Inventor: PICKERING JOHN ADRIAN
IPC: G06F3/0354
Filed: 1984-10-15
Abstract: A computer peripheral device comprising a hand-sized mobile enclosure known as a "mouse", and having a plurality of finger- or hand-operated keys which may be actuated together with the motion of the enclosure to translate positional information into coordinates as input to a computer system, is characterised by the additional facility for inputting symbols such as alpha-numerics by suitably coded actuation of the same keys.

Title: Method of operating an ink jet apparatus to control dot size
Inventor: DEBONTE WILLIAM J
IPC: B41J2/045
Filed: 1985-04-16
Abstract: The volume of ink ejected from the nozzle 202 of an ink jet printing apparatus comprising a chamber 200 and transducer 204 during one cycle of operation for printing a dot upon a recording medium is controlled within that cycle of operation by operating the ink jet apparatus via the application of a pulse train T1 to T4 having a periodicity equivalent to the dominant resonant frequency of the ink jet apparatus. In this way each pulse of the pulse train causes an ink droplet of substantially predictable volume to be ejected at the nozzle 202. A given number of successive pulses during each printing cycle is applied to the ink jet apparatus for causing an equal number of ink droplets to be ejected for controlling the boldness of the dot being printed. <IMAGE>

Title: A method for the processing of waste paper
Inventor: KONECSNY HELMUT
IPC: D21C5/02
Filed: 1986-02-26
Abstract: In a method for processing waste paper, the waste paper is firstly pulped in a breaker and then subject to preliminary cleaning. Prior to flotation and subsequent washing and bleaching, the fibrous suspension is treated in a dispersion plant, comprising an inlet and preliminary heating coil followed by a dispersion device, at a temperature of at least 50 DEG C. As a result, paper of the highest purity can be produced even with a high NCR content in the waste paper, e.g. for paper of tissue quality.
Patent GB-2172400-A (GB)
Title: A method for lithology detection
Inventor: CLERKE EDWARD ALAN
IPC: G01V1/40
Filed: 1986-03-07
Abstract: Changes in the lithology of formations surrounding a borehole are detected by monitoring the automatic gain control (AGC) level of a borehole televiewer (BHTV). A signal whose amplitude is representative of the AGC level is transmitted to the surface where the BHTV signal is restored to its original level and displayed, or the AGC signal level pulse can be monitored and displayed directly. The borehole televiewer, comprising rotating acoustic transducer which is periodically energised to produce energy that is reflected back from the borehole wall, has an AGC circuit 21 similar to that described in GB 2133882. The circuit for supplying the gain signal representing the amplitude of the gain control signal includes amplifiers 30 and 31. The gain signal is supplied via mixer circuit 14 and line driver 15 to the logging cable 16. <IMAGE>

Patent GB-2197150-A (GB)
Title: Apparatus for splash spotting
Inventor: DAVIES NYALL
IPC: G01S13/64
Filed: 1987-07-02
Abstract: Apparatus for spotting an impact produced by a shell or missile includes using a radar to obtain signals reflected from the impact comparing them with signals received before the impact. In a marine radar for detecting the location of a splash, the velocity components of the splash are also obtained using fourier transformer and a range-velocity map obtained. A target echo will occupy one cell 19, i.e. at one range and one velocity whereas the signals from the splash will occupy a number of cells 27, each having the same range brackets but different velocity spreads. Since the characteristics are different the splash may be distinguished from the target even if it occurs very close to the target. Similar spread echoes from clutter will appear both before and after the splash and thus may be distinguished. <IMAGE>

Abstract: In a ventilation arrangement, a humidity sensor is provided to sense the relative humidity within a space to be ventilated. A ventilating fan has a control arrangement such that the volume of air moved by the fan is controlled in response to the sensed relative humidity. The ventilation fan may be brought into operation above a set point relative humidity (40%) and the fan speed controlled in increasing stepped operation as the humidity rises. A timer may delay switching off of the fan when the humidity falls below a set point and may be switched off after a delay initiated by the switching off of a light.   <IMAGE>

Title: Crop harvesting apparatus and methods
Inventor: KLINNER WILFRED ERWIN
IPC: A01D41/06
Filed: 1989-01-17
Abstract: Apparatus for harvesting crop comprises a rotor 11 mounted on a mobile frame 12 and carries a succession of transverse combs 14 each formed of an array of outwardly projecting teeth 15 transverse to the direction of movement of the apparatus through the crop. Each tooth 15 is pointed with side edges diverging away from the distal tip of the tooth. The rotor rotates in the overshot mode and the combs intrude into the crop and gather crop stems between adjacent pairs of teeth and detach grain and grain heads, or other required crop parts, by rubbing or breaking the parts free from the stems. The junction of adjacent teeth 15 perferably has an enlarged aperture 21 to assist stripping and to allow withdrawal of stripped stems. In other arrangements the teeth may be replaced by a brush-like structure or by rods or other crop engaging elements, backed by plain transverse ribs for collecting and conveying detached crop parts. <IMAGE>

Title: Electronic control circuit for garage door and gate operators
Inventor: ALLEY PATRICK HYDER
IPC: E05F15/16
Filed: 1989-05-03
Abstract: An electronic control system for an electric motor driven mechanism having two opposing extremes of travel, such as a garage door, where a signal to the motor to open the door is initiated and sustained in operation by a first circuit Q1 and to close the door is initiated by a second circuit Q3 but sustained in operation by a third circuit Q2. Since all circuit states are determined by an alternate-action switch 51a-51c common to all three circuits plus two normal limit switches 52, 53 and a set-reset flip-flop IC1c-IC1d, an opening door can be stopped and started at will or by unlimited types of override sensor switches, or when closing can be reversed to run open at will or by unlimited override switches. If stopped by an override switch the motor will not restart until commanded to. The motor may be a series type motor or an induction motor. <IMAGE>

Title: Compact audio disc autochanger
Inventor: KAWAKAMI HIROSHI
IPC: G11B17/22
Filed: 1989-07-05
Abstract: To select and play one of a number of optical discs carried on trays shelved in a cartridge, a transporting table 501 is elevated to be in register with a shelf and a rack and pinion system (Figs 6 to 8) pulls the tray and disc onto the table, the final part of the drive for this being obtained from a cam wheel 703 which on one side locks a follower into a peripheral circular track to hold the rack and pinion system fully extended while the cam wheel continues to rotate, the other side of the cam wheel 703 having as many contours (720a to 720g) as there are cartridge shelves so as to lower the table from the selected shelf onto the playing deck and to raise it back to the shelf for unloading. Connection between the rack and pinion system and a selected disc tray is through a telescopic strut 800 that allows for rise and fall of the table 501. A screw drive (Figs 1, 3, 4, 5) positions the transporting table to register with a selected shelf, the table being unlatched from an index member (306) of the screw drive to allow the table to be lowered and raised by the cam wheel, the table latching back to the index member when the table returns to replace the disc in the cartridge. <IMAGE>
