Filed: 1969-11-14
Abstract: 1294097 Focusing devices CANON K K 14 Nov 1969 55818/69 Heading G2J [Also in Division H4] An optical system comprises two photo-electric elements separated by an image splitting plane, an objective lens, image splitting means and a cylindrical lens the axis of which is perpendicular to the image splitting plane. The cylindrical lens 5 in conjunction with the objective lens 1 produces two images of the object. The first image is produced by the objective lens 1 and the cylindrical lens 2 in the horizontal direction. At the elements 4 1 , 4 2 , this image is defocused and therefore the intensity of the image varies only in the horizontal direction. The second image in the vertical direction is due only to the objective lens 1 and is focused on to the photo-electric elements 4 1 , 4 2 . In a first embodiment the image splitting means is a split prism 3 which deflects the upper and lower halves of the image in opposite directions. The images are only aligned when the image is properly focused on the photo-electric elements 4 1 , 4 2 . In this case the elements have equal outputs. In a second embodiment the image splitting means is provided by having the elements spaced at equal distances from and on opposite sides of the wanted focal point (F). When the outputs of the elements are equal the image will be focused at the correct point. The outputs from the photo-cell elements are used to control the automatic focusing arrangement.

Filed: 1970-11-25
Abstract: 1324266 Eddy current brakes ROBERT BOSCH GmbH 25 Nov 1970 [5 Feb 1970] 56063/70 Heading H2A In an eddy current brake, e.g. for a motor vehicle, comprising two members constituting the brake rotor and stator of which one member, the inducing member, is connected through a switch 50 to a current source to produce when the brake is operative eddy currents in the other, induced, member, the intake of cooling air impelled through the brake by ventilating vanes 27 on the rotor is controlled by a delay device so associated with the switch 50 that when the braking current is switched on the air is impelled through the brake and, so long as the rotor continues to rotate continues to be so impelled for a period after the said current has been switched off. As shown, the numbers 11, 20 form the inducing stator and the induced rotor respectively, and comprise an energizing coil 12 embraced by claw pole-pieces 13, 14 attachable to the vehicle gear or differential casing, and a drum having a cylindrical portion 21 surrounding the polepieces and a wall 22 attached to a flange 18 of a hub 16 rotatable in a ball bearing 15 and fixed to a transmission shaft butt 17. Apertures 23 in the wall 22 form the air intake, and lead via an annular space 25 and radial passages 26 defined by the vanes 27 to axial passages 30 defined by cooling fins 28 and a sheet metal jacket 29. Axially movable in the space 25, to open (as shown in full) or close the air intake, is a flat ring 35 actuated via rods 36 and levers 38 by three solenoids 42 whose armatures 40 are biased by springs 47 to close the intake. Thus closure of switch 50 both energizes the brake and opens the cooling air intake, and upon opening the switch 50 the brake is deenergized but an NCT resistor 51 attached to one pole-piece 14, together with a switching amplifier 52 maintain energization of the solenoids 42 until the brake has cooled sufficiently. A lamp 55 on the vehicle dashboard indicates when brake cooling is operative. In one other embodiment, Fig. 3, not shown, the solenoids are replaced by expansible thermo-responsive elements associated with resistance wire heating elements, whilst in another embodiment the delay device is a time-limit relay.

The dewatering of an aqueous cellulose fibre suspension can be improved by incorporating, into the pulp suspension a water-soluble homo- or co-polymer of monomer of formula:- were X partially stands for hydrogen, and may partially stand for HCO-, CH 3 CO-, or C 2 H 5 CO- groups. This polymer may be prepared by the partial or complete acid hydrolysis of a homo- or co-polymer of an N-vinyl, N-methyl carboxylic acid amide of formula where R represents H-, CH 3 - or C 2 H 5 -. 60-100 % of these radicals may be so removed. The co-monomer may amount to 50% by wt., and may be such as to be copolymerisable with the amide by free-radical polymerisation, e.g. vinyl alcohol, a vinyl ester, an open-chain N-vinyl carboxylic acid amide, an N-vinyl lactam, a vinyl sulphonic acid, acrylic acid, methacrylic acid or an acrylic or methacrylic acid amide. The polymer may be added at a concentration of 0.05-4.00% by wt. of the dry cellulose fibres. The suspension may also contain rosin size, aluminium sulphate, and/or fillers, e.g. kaolin, china clay, talcum, heavy spar and titanium dioxide. Prior art processes involving the use of polyethylene imines and condensation products of urea and 1,2 alkylene imines in the same way are described.

Abstract: 1,242,607. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 29 Nov., 1968 [3 Jan., 1968], No. 56892/68. Heading G4R. In pattern scanning apparatus, data signals from a raster scan are consolidated in a selected direction, and detection of predetermined combinations of features in the consolidated data signals causes adjustment of the raster position in a direction at right angles to the selected direction. A character in a line of characters is scanned by a raster of vertical parallel lines to obtain data bits (32 per scan line) which are shifted into a one column (scan line) shift register, each bit being ORed with the correspondinglypositioned bit already in the register to develop a horizontal projection of the character. In case the raster overlaps the next line of characters above or below, the number of black-towhite and white-to-black transitions in the projection is counted in a sequence counter (preset to one), the nature (black or white) of the lowest bit in the projection is stored in a flip-flop, and a black bit counter counts the number of black bits in a black bar (series of consecutive black bits) in the projection to determine if the number lies between 8 and 25, then decrements the count with each black bit in a second bar (if present) to determine which bar is the longer (result stored in a sign flip-flop) and whether the modulus of the difference of the lengths exceeds 3. Logic circuitry responds to these indications and to the shift register direct to cause the raster to move up or down to centre on the character, the shift register being ring-shifted down or up respectively correspondingly, its direct connections to the logic circuitry terminating the movement at the appropriate time.
