Title: Thickness gauge
Inventor: BROWNING SHANE CAIRNES
IPC: G01B7/06
Filed: 1962-08-08
Abstract: 1,070,591. Measuring thickness electrically. ENGLISH ELECTRIC CO. Ltd. Nov. 8, 1963 [Aug. 8, 1962], No. 30459/62. Heading G1N. [Also in Division G3] The thickness of a strip 10, Fig. 1, (e.g. in a rolling mill) is measured by passing it between two rollers 12a, 12b which are biased towards the strip, movement of each roller perpendicular to the strip being used to rotate the rotor of a synchro device 14a, 14b, the rollers and synchros being mounted on a floating unit (20, Fig. 2 not shown) so that random lateral displacements of the moving strip cause one roller to engage a stop (27) and thereby move the whole unit (20) so that the unit is prevented from exerting a lateral force on the strip. The stator windings of the two synchros are interconnected either directly, in which case the difference in magnitude between the A.C. applied to the rotor of 14a Fig. 1, and that supplied from the rotor of 14b indicates the actual strip thickness, or else they are interconnected via a differential transformer 15 which introduces an angular displacement between the two stator fields and thus sets a datum strip thickness, any output from a phase sensitive comparator 16 then representing deviations from the required thickness. These deviations may be indicated, or else amplified (17) and used to control a motor 18 which adjusts the gap between the main rollers 11. The sensing rollers, which may be of ceramic or vitreous material, are mounted in C-shaped members 22, Figs. 2-4 (not shown) on the floating unit (20) which is resiliently mounted by arms (21) on a fixed base member (19) attached to the mill. Rotational movement of the C-shaped roller-holders (22) is transmitted by precision gear-boxes (24) to the synchro.
Patent GB-1421945-A (GB)
Title: Data processing system
IPC: G06F12/1009
Filed: 1973-06-27
Abstract: 1421945 Virtual storage; page replacement INTERNATIONAL BUSINESS MACHINES CORP 27 June 1973 [24 July 1972] 30476/73 Heading G4A  In a virtual memory system a page in working storage is replaced by copying the page into backing storage and subsequently overwriting the page with a replacement, the replaced page being available to an associated processor during the copying and up until immediately prior to the commencement of overwriting. Overwriting is inhibited and a further page in the working store selected to accommodate the replacement page if the first page is modified following commencement of copying. Apart from features relating to page replacement the system is wholly conventional and includes a main (working) store, an associative store for virtual-to-real address translations, and a key store containing, for each page in the main store, a memory protection key and an " alter bit " which is set to one when the corresponding page is modified. An area of the main store reserved for operating system program data contains an " available queue " which (at least initially) indicates which page spaces in the main store are unoccupied and an " in-use " queue indicating pages being used in an order, e.g. least recently used, in which they are to be overwritten when this is necessitated by page transfers into the main store from backing (e.g. disc) storage. Steps are taken to maintain at least N entries in the " available queue " by transferring entries from the " in-use " queue in a manner similar to that described below when the " available queue " is empty. When a required page is not resident in the main memory the first entry in the " available queue" is selected, and the corresponding " alter bit " examined. If the corresponding page is unmodified it is overwritten by the required page, otherwise the page is transferred to the " in-use queue " and the procedure repeated. If the available queue is or becomes empty the first entry in the " in-use queue " is selected and the corresponding " alter bit " examined. If this bit indicates that the page has not been modified it is overwritten by the required page. If the page has been modified the " alter bit " is reset to zero, the page copied into backing storage, and a corresponding entry made in the available queue. The whole procedure is then repeated. However since an entry now exists in the " available queue " the copied page is selected for overwriting unless the examination of the " alter bit " indicates that the page has been modified during the copying process. If it has been so modified it is returned to the " in-use queue " and again the procedure is repeated. In all cases the page selected for overwriting is rendered invalid, i.e. inaccessible, immediately prior to overwriting.

Title: Improved film driving mechanism for film sound recording and reproducing apparatus
IPC: G11B15/50
Filed: 1932-10-31
Abstract: 390,452. Driving sound-films. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Elmer, L. A. ; 102, Riggs Place, West Orange, and MacDougall, H. W. ; 514, North Maple Avenue, East Orange, both in New Jersey, U.S.A.) Oct. 31, 1932, No. 30579. Convention date, Jan. 7. [Class 40 (ii).] A sound-film driving mechanism comprises a film-feeding roller driven through a floating or frictional coupling and a film-driving sprocket driven through a resilient member. As shown, separate shafts 37, 18 are extended from the gear-box of a combined motion picture and sound-reproducing apparatus to drive a friction roller 3 and a sprocket 4, respectively, which feed the film 1 past the sound-reproducing head 43. The drive to the roller 3 is transmitted through a fluid coupling 40 consisting of an outer member 34 driven from the shaft 37 and an inner member 33 driven through the medium of a fluid 39 which may be oil. A flywheel 5 is provided on the shaft 4 of the roller 3 and, in order that a strain may not be imposed upon the film at starting, the roller 3 is coupled to its shaft through a clutch comprising a friction disc 8 maintained against the roller 3 by a spring 9, washer 10 and nut 11. The sprocket 14 is driven from the shaft 18 through gears 16, 17 and is held against appreciable longitudinal displacement by bearings 23. The drive is transmitted through a spring 20 which allows the sprocket 14 to rotate somewhat on the shaft 19 depending upon the load and so prevents noise and irregularity of film movement due to any misalignment of the film perforations with the sprocket teeth. In place of the floating coupling 40, an electromagnetic coupling or a coupling acting on the principle of a turbine may be employed.

Abstract: 175,352. Harris, E. W. Nov. 3, 1920. Mineral and tar oils, purifying.-Small globules of water suspended in oil or other liquid are made to coalesce by passing the emulsion between charged electrodes in a, closed vessel; the water then settles. A potential of 10,000 to 50,000 volts may be used. In the apparatus shown, impure oil enters a tank 1 by a pipe 2 connected to a perforated ring 26, pure oil leaving by a pipe 3, and water by a pipe 4. The high potential electrode consists of a stationary cylinder 8 supported by a. rod 7 from an insulator 5. This is surrounded by a rotating electrode, in electrical connection with the tank, consisting of inclined angle iron bars 11 secured at the top to a ring 12 bearing against a plate 16 and at the bottom to a spider 13 secured to the hub 15. The hub 15 is driven by a pulley 23 through gearing 20 supported on a plate 25. Means are provided tointerrupt the electric circuit and also the supply of oil for a period in the event of short-circuiting by the formation of a chain of water globules between the electrodes. The electrodes are connected to the secondary 35 of a transformer in the primary circuit of which are included a reactance 53, electromagnets 38, 48, and a movable switch member 41. The switch member 41 is connected with lost motion to the armature 39 of the electromagnet 38 so as to be lifted suddenly when the current becomes excessive. Return of the switch member is retarded by a dash pot 46 having a check valve 47 which allows rapid rise of the switch member. When the current is broken the inlet 2 is closed by a valve 51 attached to the armature 50 of the electromagnet 48 by which it is normally held open. The water discharge pipe 4 comprises an ascending member 29 having a valve 28 at the bottom and a vent 30 at the top, and a descending member 31.
