Title: Pipette of adjustable volume
IPC: B01L3/02
Filed: 1979-05-21
Abstract: A pipette with an adjustable volume has a stop bushing 19 provided with outside threading fitted into corresponding threading 10 formed inside the frame of the pipette. The upper part of the stop bushing and the piston shaft 3 are provided with jointly operative means 20 that prevent their turning in relation to each other but, nevertheless, permit movement of the piston shaft in relation to the stop bushing in the direction of the piston shaft. When the press button 2 is turned, the stop bushing constituting the upper stop of the piston can be moved by means of the threaded joint inside the pipette frame upwards or downwards so as to adjust the volume of the pipette. One or several grooves have been formed in the longitudinal direction of the stop bushing on the outer face of the bushing, and a locking tip or means is fastened to the pipette frame by means of a spring means to constitute a jointly operative means with said groove, which locking tip or means is arranged so that it is pressed by a spring against the outer face of the stop bushing. Hereby the groove is shifted periodically, when the bushing is being turned, over the locking tip into a position in which it locks the adjustment of the pipette at a certain volume value and in this way forms a periodically or stepwise adjustable pipettable volume in the pipette.   <IMAGE>

Title: Root crop harvester
IPC: A01D25/04
Filed: 1979-09-26
Abstract: In a root crop harvester, a header assembly 12 feeds beets from digger unit 42 to a conveyor 52 and thence to a transverse conveyor which converges the crop. The transverse conveyor comprises a flighted grab roll 56 and two short rolls 58 and 60 with a central space between them. The converged crop drops through this space on to an upwardly inclined fore-and-aft conveyor formed by pairs of contra- rotating grab rolls 98 and 100, 102 and 104, 106 and 108. The beets are tumbled up this conveyor and discharged sideways into an elevating wheel conveyor 92 which, with the fore-and-aft conveyor alongside, lies between the ground wheels 80 of the processing chassis. The sideways discharge is promoted by rotating rear parts 130, 132, 134 of the rolls 98, 102, 106 in opposite sense to the front parts 136, 138, 140 so that, at the rear, all six rolls urge the beets across to the wheel conveyor 92. In addition, the incline of the rolls increases from the roll 98 to the roll 108 so that the rear part of the fore-and-aft conveyor has a transverse slope down towards the wheel conveyor. <IMAGE>

Title: Connector assembly for a cable
IPC: H01R13/424
Filed: 1980-04-30
Abstract: A connector assembly includes an annular connector body (40) housing an insulator (46) which holds a plurality of terminal contacts (48) to which the cable conductors (22) are connected, in use. An annular adaptor fitting (28) surrounds the conductors and has one tubular end sized to telescopically receive the braided cable conduit (14, 18). The opposite end is provided with a conically tapered inner bore face (58) diverging in a direction away from the secured cable. An oversize resilient grommet (51) is fitted over the cable conductors and is compressed within the adaptor fitting bore. A conventional locking nut (60) cooperates with an exterior shoulder on the adaptor fitting in order to draw the adaptor fitting snug against the annular body thereby compressing the grommet between the adaptor fitting, the annular body, the insulator and the conductors. A coupling sleeve can cooperate with an exterior shoulder on the annular body to lock the connector assembly mechanically to another connector or terminal board. The cable conductors may be electrical conductors or light transmitting fibre rods. <IMAGE>

Title: Electrolytic Cells
IPC: C25C7/06
Filed: 1981-02-11
Abstract: The weight of the cathode in an electrolytic cell is monitored to determine the total and incremental weights of silver deposited, this information being used to control the electrolysis particularly the time of electrolysis. When used for a photographic development tank the area of the film being processed can be used to modify the control (GB 2033612). The weight of the cathode may be determined by the movement of the cathode or its support under gravity, e.g. by the expansion or contraction of mechanical, electrical electronic or optical devices, or by the force needed to be applied by any device to maintain the cathode in a given position.

Patent GB-2100904-A (GB)
Title: Character recognition systems and methods
Inventor: BURLEY MICHAEL
IPC: G06V10/34
Filed: 1981-07-03
Abstract: A character recognition system has a linear array of photocells which is moved across the character to produce an array of pixels arranged in columns and rows. These are noise- reduced by relating the grey-level of each pixel to a continuously up-dated reference level representing the current "whitest white" level and each pixel is converted into a "black" pixel or a "white" pixel. A velocity compensation unit then compensates for varying velocity of the wand by ensuring that each character is represented by only 16 columns of pixels (arranged side by side across its width). The result is a 16x16 matrix of pixels. Character recognition is carried out by "thinning", 564, each character representation so that it is, in general, only one pixel wide. Then directional vectors are assigned to pairs of adjacent black pixels at 506. These vectors are then processed to build up a total vector representation of the character in which it is represented by vectors each having one of eight predetermined directions. The resultant vector representation is compared, 508, with a set of reference vector representations. <IMAGE>

Title: Radar tracking system
Inventor: JOYNSON DAVID WILLIAM
IPC: G01S13/524
Filed: 1982-11-19
Abstract: A radar tracking system for an anti-aircraft missile, includes angle tracking, doppler tracking and range tracking feedback loops operating on sum and difference channels. Fast fourier transform digital filters are used to provide a frequency spectrum of the sum and difference I.F. channels and detection and confirmation algorithms are employed for selecting the F.F.T. target 'bin'. Adjacent F.F.T. bins are used to simulate a bin centred on the target frequency, shifts of the latter with target/ missile acceleration causing frequency errors which are detected by a discriminator and used to control the target I.F. Confirmation of target acquisition is achieved by successive summations of the target bin power the totals being accumulated and compared with upper and lower thresholds. Confirmation and rejection results from total levels outside the thresholds while further accumulation and comparison follow the intermediate condition. Multiple target discrimination is provided by comparison of two S/N ratios, one obtained from target bin power and average power, and the other obtained from coherent power in the target bin and overall power in the target bin.
