Abstract: 1390404 Optical scanner RCA CORPORATION 21 April 1972 [30 April 1971] 18576/72 Heading G4M The validity of optically recorded data, e.g. on a label (or printed) on an item of merchandise in a supermarket, is checked using a reader (Fig. 1, not shown) and the circuitry of Fig. 3. The data is recorded on a label, Fig. 2a, in bands of differing optical reflectivity, e.g. black and white, each band having a standard thickness, and the data portion 44 is arranged so that there are not more than four bands of any one colour together. The data is recorded in a BCD type format in which each digit can be converted to a standard binary code by substracting two therefrom if its 2<SP>3</SP> bit is 0 and by subtracting four therefrom if its 2<SP>3</SP> bit is 1. The data 44 is preceded by a preamble section 42 comprising four black bands and one white band (or vice versa) and succeeded by an end section 46 comprising succeeding white, black, and white bands followed by a bull's eye 58 of at least seven bands width. The item of merchanidise is carried on a conveyer belt over a viewing slit and a laser scanning beam 10 reads the data and passes it via a photo-multiplier and amplifier to black/ white, white/black transition detectors 62, 60. Signals pass via OR gate 68 to circuit 91 which generates clock and strobe signals and to AND gate 88 which checks that two transitions do not occur too close together, i.e. that a noise pulse has not occurred. The clock pulses are generated every time there is a transition and, also, when there are no transitions due to several 1's and 0's together, at the approximate positions between adjacent bits using units 92, 93, 95, 96. The transitions also set and reset flip-flop 66 to pass bits to a reversible shift register 70. AND gate 78 reads the first six bits to check whether the preamble 42 has been read and each successive group of four bits is checked to determine whether they are allowable combinations in AND gate 84. When a counter 100 reaches a count indicating that the scan beam should have reached the first band of the bulls eye 58, logic unit 86 checks to see if the preceding, white, black, white, black pattern has been received by the shift register. AND gate 120 determines that the scan beam is passing through, or nearly through, the bulls eye by determining that there are no colour transitions in this region. AND gates 72, 74 then ensure that the data read from outside to centre agrees with that from centre to outside. If any of these checks fail, flip-flop 79 is reset via OR gate 122 to reset flip-flop 105, to reverse counter 100 and shift register 70. AND gate 112 sends a valid read signal, e.g. to a computer. These checks are designed to eliminate errors caused by background noise or by faulty reading of the label.

Filed: 1943-11-10
Abstract: 571,861. Loom stop-motions. CARGILL, H. S., and GALLOWAY, J. A. Nov. 10, 1943, No. 18642. [Class 142 (i)] On actuation of the warp protector stopmotion when the shuttle is not properly boxed the warp beam is shifted in a direction to reduce the distance of the warp line between the last inserted pick and the point where the warp leaves the beam, thus reducing warp tension. If a shuttle fails to actuate a warp protector 17 and raise it clear of a frog 3 the protector 17 engages the frog 3, moves a rod 4, and, through a bracket 1, lifts the warp beam 13. Shift of the beam 13 reduces the distance between the anchorage points of the drag chains 6.

Title: Improvements in horizontal telemeters containing the base-line within itself
IPC: G01C3/12
Filed: 1920-07-07
Abstract: 147,106. Zeiss, C., [Firm of]. March 8, 1917, [Convention date]. Range-finders.-Relates to the type of range-finder described in Specification 12177/07 in which the base line is above the observer, and the separating-prism system is on the same level as the entrance apertures. According to the present invention the separating-prism system is at the level of the eyepiece, and the objectives and a necessary additional reflecting system together with the prism system are contained in a rigid tubular system. Several examples are described, one of which is of the stereoscopic type. In that shown in Figs. 1 and 2, the reflecting systems comprise two pentagonal prisms a<1>, a<2>, having ridge surfaces as shown, rotatable refracting prisms b<1>, b<2>, and an additional reflecting system consisting of two prisms d<1> d<2> situated in the centre of the base line. The axial rays are reflected through 90 degrees in a plane perpendicular to the base line to the separating-prism system, consisting of two reflecting prisms e' e<2> and of crossed reflecting prisms f<1> f<2>. The eyepiece comprises lenses g<1> g<2>. In this construction only a displacement of the separating-prism system in the direction of the axis of inspection, or a rotation about the base line, will effect a relative movement of the two images observed. Figs. 10 and 12 show an arrangement by which an erect image and an inverted image are observed, the reflecting system comprising additional reflecting prisms d<8>, d<9>. one of which is of ridge form. The objectives are carried in a flattened tubular body k<6>, and the rays are received by the eyepiece k<8> through the prisms f<5> f<6>. The upper half of the cemented surface is formed on both sides as a reflector. In a further example, the reflecting prisms are so arranged that the axial rays are reflected downward to a single prism f<7>, Fig. 15, and meet in the line f<12> separating the two surfaces f<10> f<11>, without having been previously reflected in the separating system.

Title: Improvements in and relating to reversing mechanism for machine tool tables
IPC: B23Q5/033
Filed: 1935-07-08
Abstract: 454,682. Grinding. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Norton Co. ; New Bond Street, Worcester, Massachusetts, U.S.A.) July 8, 1935, No. 19411. [Class 60] [See also Group XXIX] In a grinding or other machine having a table reciprocated by a fluidactuated motor, the movement of the table at each reversal is successively decelerated and accelerated by the operation of a throttle valve controlling the exhaust fluid from the motor, the throttle valve being controlled independently of the motor reversing valve. In the apparatus shown the table 11 is being reciprocated on a base 10 by the rod 18 of a piston 17 reciprocating in a cylinder 15. The piston 17 is operated by fluid supplied by a pump 32 through a throttle valve 27 and a reversing valve 22 to one side of the piston, the fluid on the other side of the piston being returned to the pump reservoir 33 through the throttle and reversing valves. The reversing valve 22 comprises two balanced pistons 24, 25 slidable in a ported sleeve 23 to reverse the direction of the fluid flowing through pipes 43 and 79 to the cylinder 15. The throttle valve 27 comprises three pistons 28, 29, 30 sliding within a ported sleeve 31 and adapted when moved to the right to throttle simultaneously both the supply and exhaust of fluid passing through the reversing valve 22. The reversing valve 22 is formed with an elongated slot 53 engaged by a pin 52 on a link 50 connected to a lever 48, which is formed with a V-shaped projection 58 engaged by the V-shaped end 57 of a spring-pressed lever 55. The lever 48 carries adjustable screws 74, 75 which are engaged when the table reaches the ends of its strokes by pins 72, 73 on dogs 65, 66 adjustably secured to the table. The lever 48 is then turned about its pivot 49 thereby lifting the lever 55. When the pin 52 reaches the end of the slot 53 the lever 48 is rapidly moved by the lever 55 to operate the valve 22 and reverse the direction of movement of the piston 17. Before each operation of the reversing valve 22 the throttle valve 27 is operated to reduce the speed of the table by a bell-crank lever 91 engaging cam plates 95, 96 on the dogs 65, 66. The normal speed of the table may be adjusted by means of a cam 98 which limits the movement of the throttle valve to the left by a spring 104. The cam 98 is mounted on a lever 100 carrying a spring- pressed plunger 101 adapted to engage notches in an arcuate member 103. An adjustable screw 94 on the lever 91 is provided to allow variation of the throttling at reversal. The lever 48 may be operated manually to reverse the movement of the table during its normal stroke, the lever 91 then being actuated by an arm 105 on the lever 55 to operate the throttle valve.
