Title: Improvements in extraction control devices on steam or gas turbines
IPC: F01K7/34
Filed: 1941-12-29
Abstract: 550,184. Fluid-pressure servomotor control systems. ESCHER WYSS MASCHINENFABRIKEN AKT.-GES. Dec. 29, 1941, No. 16730. Convention date, Dec. 24, 1940. [Class 135] [Also in Group XXVI] Admission and interstage valves of an extraction turbine are controlled by a speedgovernor and an extraction pressure governor. The speedgovernor 1 moves the beam 15 by means of the pistoned sleeve 27 under the control of a restoring arm 14 which makes contact with the beam at a point between the operative connections of the admission valve 36 and the interstage valve 39 with the beam. The sleeve 27, a piston 35, a restoring arm 23 and piston 28 form a servo-motor for the valve 36. A sleeve 30, a piston 38, a restoring arm 19 and piston 66 form a servo-motor for the valve 39. The sleeves 27, 30 are connected to the beam at points 24,. 18. The extraction pressure governor is connected to the beam at the point 9 and, when it operates, the beam moves about the point 24. Pressure fluid from a chamber 25 passes through a bore 60 in the piston 27 into a chamber 63. A leak from the chamber 63 by way of a nozzle 6 is controlled by the upper end of the speed-governor spindle 4. If the turbine speed rises, the leak is diminished, the pressure above the piston 27 rises and the piston moves. downward turning the beam clockwise. The restoring arm 14 follows the beam and raises a strut 11. This permits the pressure fluid to raise the nozzle 6 and restore the leak. Downward movement of the piston 27, with. the sleeve with which it is integral, moves a port away from a piston 28 and allows pressure fluid under the piston 35 to leak whereupon a spring 34 reduces the opening of the valve 36 until the restoring arm 23 lowers the piston 28 to cover the port and stop the leak. The sleeve 30 and piston 66 similarly operate the interstage valve 39 when the beam is moved. The bellows 46, responsive to the extraction' pressure, moves a deflector 50 to intercept a jet 51 and so vary the pressure reproduced by the jet in a chamber 57 and below. the piston 55. The restoring, arms 19, 23 are mounted on plates 12, 10 which can be turned to bring the arms into the directions desired for any particular assembly.

Title: Improvements relating to record cards for data processing devices
IPC: G06F3/06
Filed: 1964-04-23
Abstract: 993,113. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 23, 1964 [May 16, 1963], No. 16778/64. Heading G4M. A record card, Fig. 1, has zone 14a-14c in which the characters 0-9 are printed in red, and further zones 12a-12c in which groups of code marks corresponding to these characters are printed in black, the code illustrated being binarycoded decimal with an even parity check bit. Information is recorded on the card, e.g. by a meter reader, by making a black mark over the appropriate characters in zones 14a-14c.. The card is sensed by passing it beneath a group of ten photo-cells which are insensitive to red light. As the black line Z1 passes the photocells, AND gate 47, Fig. 5, produces a pulse to trigger a timing circuit 50, and a synchronizing pulse is transmitted to remote data-processing equipment through OR gate 69. Trigger SS1 enables the AND gates 61 in a set of latches 60-0 to 60-9 so that when the black mark in zone 14a is sensed the corresponding trigger 63 is set to enable AND gate 65, and immediately afterwards AND gates 67 are enabled by trigger SS3. Pulses derived from the code marks in zone 12a corresponding to selected character are then passed by AND gate 67 in the appropriate latch 60 and are transmitted to the data-processing equipment. Finally, trigger SS2 resets the set trigger 63 and the system is ready to start a fresh cycle when the next black line Z1 is sensed. The card shown in Fig. 2 is marked in zones 34 to indicate alphabetic or numeric characters. In sensing such a card, relay M-1, Fig. 5 is energized to enable gates 67 during the complete sensing cycle. When the mark in zone 34 is sensed the corresponding trigger 63 is set as before, but the pulse derived from this mark is now also passed through gates 65, 67 and forms part of the code group transmitted.

Abstract: 1500800 Automatic focusing systems in optical instruments GEOMETRIC DATA CORP 23 April 1975 [29 April 1974] 16881/75 Heading G1A [Also in Division G3] An automatic focusing system in an optical instrument comprises a flying spot scanner the beam from which, in use, is directed through the optical instrument, on to an object to be viewed, means responsive to the beam after it has fallen, in use, on the object for providing information concerning the focus of the beam on the object and focusing means driven according to said information to focus the optical instrument. As disclosed the beam is caused to pass through the object and the density of colour of the transmitted beam in several positions of the objective of the optical instrument is used to determine the optimum focus of the instrument. In this respect the transmitted beam falls on a light sensitive means e.g. photo-multipliers for generating a signal corresponding to the brightness of the light and a plurality of quentization means are provided each of which is responsive to the signal at a different threshold level and generates a binary quentization representative of the signal. The quentization means includes a plurality of quentizos each of which being enabled when the signal exceeds the threshold level for that quentizer. Means responsive to the quentization signal are provided for weighing the binary signals generated by the quentizers differently in accordance with the intensity of the threshold signal level for enabling the quentizers. The instrument e.g. a microscope is focused using the weighted binary signals in a series of steps. Firstly the objective of the instrument is moved 1 Á from its position of optimum focus of which a prior object had been inspected. Then at each line of scan of the spot the objective is moved ¢ Á towards the optimum focus. As the objective moves toward the optimum focus the colour density measurement increases and then after the optimum focus is passed the colour density measurement decreases again. At this point the ¢ Á movements are terminated and the objective moved back to its position of optimum focus. Should the objective, after its 1 Á shift be moved away from the position of optimum focus in the ¢ Á movements the circuits of the focusing means note this and reverse movement of the objective. The focusing scan comprises the intermediate of three scans in the described embodiment in which white cells in a blood sample are classified. The first scan comprises are for searching for the white cell and the third scan comprises the classification scan. The scanning system for location and classification of patterns used with the automatic focusing system of the present invention is disclosed fully in Specification 1473684, the color processor and quentizer is disclosed fully in Specification 1426311 and the mounting and fine focusing of the objective is fully disclosed in Specification 1476583.
