Filed: 1971-02-05
Abstract: 1359883 Nuclear radiation detectors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 18 Jan 1972 [5 Feb 1971] 4078/71 Heading G1A [Also in Divison H3] Pulses from a nuclear detector are applied to a shaping circuit through a gate which blocks the pulses for a time greater than the longest collection time of the detector. The collection time depends upon the point of interaction of the particle and the blocking therefore decreases erros due to the initial part of the pulse. As shown, the output of the detector 12 is integrated at 14, 16 and applied to a discriminator 24 which, upon detection of the onset of a pulse, operates a monostable circuit 38 which opens a bipolar or F.E.T gate 10. The pulse is applied to the gate via a delay sufficient to allow the gate to open. The gate is closed after the monostable period and the remaining part of the pulse is fed to a shaper comprising an integrator and a differentiator. The detector may be of the semiconductor or proportional counter type.

Filed: 1949-02-18
Abstract: 663,053. Thermally-actuated valves. CANNON IRON FOUNDRIES, Ltd. Feb. 14, 1950 [Feb. 18, 1949] No. 4432/49. Class 135 A valve for controlling the supply of fuel to an oven is itself controlled by a thermal element, and means to adjust the control point of the device comprises a ball located in a wedge-shaped space between juxtaposed surfaces pertaining respectively to the thermal element and to the valve, the ball being so connected to the setting device that it is moved positively in both senses. In an embodiment, the valve housing is provided with an inlet 4 leading to a groove 2 and an outlet (not shown) leading from a groove 3, and communication between the two grooves is controlled by a valve 7. The valve is loaded by a spring 8 and carries a short spindle 13 which can slide in a bore also housing a slidable member 16 carried by the thermal element. The latter comprises an invar steel rod 7 connected at its lower end to a brass tube 18. Movement of member 16 is transmitted to the valve spindle 13 through a ball 28, and, as the upper surface of member 16 is obliquely shaped, adjustment of the position of the ball in the wedge-shaped space between the two members will adjust the datum control point. Ball 28 runs in grooves in the two abutting surfaces and is carried by a rod whose other end is ball-shaped and is housed in a socket in a screwed rod 21 carrying a setting knob 23. A screwed sleeve 20 interposed between the rod 21 and the housing enables the initial adjustment of the ball 28 to be made. Niting pins 25, 26 limit the rotation of the setting rod, and a pin 30 carried by the valve housing engages in a slot in valve disc 7 and prevents the latter from rotating. A gauze filter 5 is fitted in the inlet.

Title: Improvements in and relating to television and like arts
IPC: H04N5/202
Filed: 1933-02-13
Abstract: 420,065. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, BLYTHEN, F., Heathcote, Keith Road, both in Hayes, and HARDWICK, J., 66, Drayton Gardens, West Drayton, both in Middlesex. Feb. 13, 1933, No. 4437. [Classes 40 (iii) and 40 (v)] In a television system having a receiver of the cathode-ray type, curvature of the lightintensity, grid-voltage characteristic is neutralized by means of a thermionic valve which produces an equal and opposite distortion at the transmitter or receiver or both. When the characteristic is such that contrast is enhanced in the bright parts of a picture and depressed in the dark parts, modulated carrier current may be applied to a grid-leak rectifier 1 whose screen grid 3 carries a lower potential than usual while its anode resistance 5 is connected to the cathode-ray tube 2 in such manner that the brightness-distortion due to the valve 1 compensates that due to the tube 2. For use with a cathode-ray tube whose characteristic is curved in the opposite manner to that described above, the valve 1 is arranged to operate as an anode-bend detector. The amount of compensation can be adjusted by varying the grid bias. When low-frequency components have been eliminated from the signals they may be restored by a system controlled by the maximum and minimum values of the signals.

Title: Improvements in or relating to machinery for cutting out pieces of plastic material from a continuously moving sheet
IPC: A21C11/10
Filed: 1946-02-13
Abstract: 607,904. Cutting-out pieces from web material. VICARS, Ltd., T. & T., and CROSLAND, E. M. Feb. 13, 1946, No. 4457. [Class 31(i)] [Also in Group V] In a machine for cutting out pieces from a continuously moving sheet or web of material, in which a cutting head is reciprocated in two perpendicular directions so that the cutters describe a closed path in space, the reciprocation parallel to the web movement is effected by a lever of the first order, whose pivot is adjustable to control the length of horizontal travel. A web 2 such as dough carried on a conveyer 1 passes over a table 3, in end extensions of which are formed guides for rods 6 carrying a cutter head 5 and cutters 4. The rods 6 are pivoted to rotating crank pins 7 on a shaft 8, and are fulcrummed about blocks 10 carried on arms 11 slidable vertically on fixed guides 18 by the rotation of a wheel 17 and screwed rod 13, whereby the blocks 10 slide in slots 9 in the rods 6 to vary the horizontal throw of the cutters, the vertical movement being determined by the crank pins 7. The table 3 shares the horizontal reciprocation of the rods 6, being mounted on arms 20 bored to receive an eccentric bush 21 rotatably mounted about a boss 22 on the frame of the machine, the bush 21 having a worm segment 24 engaging a worm 25, whereby the height of the table is adjustable by the hand-wheel 28. During the cutting stroke, the cutters, web and table move at the same speed, to ensure a clean cut. The required adjustment of the blocks 10 depends on the size of the cutters and the required space betwen cut-out portions.

Title: Character recognition systems
IPC: G06V30/10
Filed: 1974-01-31
Abstract: 1442269 Character recognition systems INTERNATIONAL BUSINESS MACHINES CORP 31 Jan 1974 [19 March 1973] 04509/74 Heading G4R During an initial raster scan of one or more characters the number of character segments lying in each of several angular ranges is determined. A signal indicative of the range containing most segments controls the orientation of the raster so that the line scan is approximately parallel to those segments during a subsequent recognition scan. One or more characters, which may be handwritten, are raster scanned by a cathode ray tube flying spot scanner. A photo-cell receives the reflected light and passes the signal to a matrix store which stores a digital simulation of the character shape. During the initial scan the scan lines are vertical. The outputs of certain of the cells of the matrix are fed to three logic circuits. Each circuit detects the presence or absence of a line segment in a corresponding angular range by responding to the simultaneous presence of character bits in some of the cells and the absence of character bits in others of the cells (Figs. 3a-3c, not shown). At the end of each raster frame corresponding counters are incremented. The counter holding the highest count at the end of the initial scan, which may cover the whole document, adjusts the scan control circuit of the c.r.t. For example, in the case of the numerals shown in Fig. 2a the initial scan will show that the majority of the line segments lie at about 60 degrees. The scan lines are rotated to 60 degrees during the recognition scan so these segments appear in the matrix store approximately upright, Fig. 2b. Segments at other slopes, e.g. numeral 1, will be stored with a slope which differs from their actual slope. The characters now in the matrix store are recognized in known manner.
