Title: Improved Method of and Means for Building Reinforced Concrete Ships.
Inventor: TIRIFAHY LEON
IPC: B63B5/16
Filed: 1919-06-25
Abstract: 128,949. Tirifahy, L. June 25, 1918, [Convention date]. Concrete vessels.-Ships and other floating bodies of concrete are cast in one piece to form a monolithic structure containing the metal reinforcement or framing. To ensure the descent and penetration of the concrete into all the interstices of the mould and reinforcement vibrations are imparted during the casting process to the inner and outer shutterings which are made of a rigid but elastic material, e.g. metal sheets. The frames or members 1 of the structure are arranged so that the thickness of the walls 2 is the minimum that can be attained by concreting. To assist to this end, tie-bars are made of rectangular or similar section having the smaller diameter in the direction of the thickness of the walls. The various parts of the reinforcements are hooked together as at the corners 16, 17 so that the structure is selfsustaining without the concrete. All the corners of the ship and moulds are rounded with the object of reducing the tendency of the concrete to crack. Special reinforcements 18, 25, 23 are introduced at the gunwale, at the sides, and at the turn of the bilge, as shown, connected to the main structure by ties. The shutterings are of just sufficient rigidity to avoid permanent deformation, but have elasticity sufficient to receive, vibratory motion under mechanical shocks, and may be made of sheet metal provided with stiffeners. The outer shuttering is supported by trestles 40 situated at intervals along the ship's side; the side shuttering being directly supported from the trestles 40, and the shuttering for the bottom being carried by removable bars 30 secured to the trestles by wedges 31, 33. This construction enables the bottom shuttering to be in sections, thereby providing a ready means of completing the bottom of the vessel sectionally and replacing the shuttering for the purpose of support. The ship is built in a dock, and floated out when completed, the shutterings being used again for the construction of other vessels.

Title: Shift register
IPC: G11C19/04
Filed: 1959-05-11
Abstract: 921,907. Magnetic core data-storage apparatus. ATVIDABERGS INDUSTRIER A.B. May 11, 1959 [July 1, 1958], No. 16076/59. Class 106 (1). A shift register comprises, as shown, a matrix of magnetic cores having ten rows (1-10) and five columns for storing nine binary-coded decimal digits each in a row, upward shift being effected one row at a time (starting with row 2 into row 1, which is normally empty at the start of a shift cycle) by the successive outputs of pulse generators 11, 12 . . . A cycle is started by a pulse from 30 and the pulse generated by each of 11, 12 ... is longer than, and starts simultaneously with, a pulse from an auxiliary generator 21 providing a halfstrength reset pulse to all cores of the matrix by windings (not shown) on line 22. Each output of 11, 12 . . . is applied as a half-strength reset pulse to one row and a half-strength set pulse to the row above, so that all set cores in the former row are reset to provide output signals on respective lines 8, which signals are amplified, delayed beyond the end of the output of 21, and fed back to the columns on lines 9 as half-strength set pulses to re-enter the information in the row above. Thus in one cycle the decimal digits are each shifted upwards one row; the last output (from the lowest pulse generator) shifts the digit from row 1 into row 10, or alternatively row 1 may be emptied and a new digit previously entered on to cores 36 transferred into row 10. Since the signals in units 7 at successive pulse generator output times represent the successive decimal digits each in parallel binary coded form, the contents of the register may be printed out by electromagnets controlled by the outputs of units 7.

Title: Filter press
IPC: B01D25/127
Filed: 1972-04-07
Abstract: 1393372 Filter presses KURITA MACHINERY MFG CO LTD 7 April 1972 [3 June 1971] 16117/72 Heading B1D A filter press having alternate frames 2 and recessed plates 1 is provided with endless bands of filter cloth 3, each of which extends across a recessed side of a plate to form a two-ply filter when the plates and frames are pressed together, and the bands being wound around rollers 11 and 12 so that, when the plates and frames are separated at the end of a filtration cycle, each band can be made to travel whereby those portions which were on the filtrate side replace those portions on the side formerly facing the liquid-being filtered. With the plates and frames in pressing contact, the liquid-tobefiltered is introduced into the press through passage 4 and flows in parallel to chambers 5. After closing passage 4, liquid passes through the two layers of filter cloth into chambers 7 due to squeezing by flexible containers 10, which are supplied with pressure, fluid. The filtrate is discharged through passage 6. At the end of the filtration cycle, the end plate 18 is retracted by hydraulic cylinder 21 thereby separating the plates and frames which are supported on side bars 22 and are connected by bolts 24. The movement of end plate 18 operates a switch which starts drive means 8; and shafts 15, gears 16 and rollers 11 are rotated so that the portions 3a of the bands 3 formerly facing chambers 5 are replaced by those portions formely facing chambers 7. The amount of rotation to be given to the rollers 11 is governed by controlling the drive means by a timer or cam in operative relation to a limit switch which detects the movement of the endless filter bands within the desired range. The filter cake either drops out of the press or is removed from the filter bands by scrapers 25 and brushes 26. Wash liquid may be forced out of the brushes. At the beginning of each filtering cycle, the filtrate may be returned to the feed materials by an automatically operated valve.

Title: Improvements in or relating to electron multipliers
IPC: H01J43/08
Filed: 1939-06-06
Abstract: 530,260. Electron multipliers. BAIRD TELEVISION, Ltd., and GRAHAM, G. E. G. June 6, 1939, No. 16556. [Class 39 (i)] In an electron multiplier the primary electron beam is formed into a velocity spectrum which is subjected to selective acceleration, so that all the electrons in the beam acquire substantially the same velocity. Electrons from a cathode 1 are accelerated by an anode 2 and are acted on by a magnetic field in the space 3 and whose lines of force run perpendicular to the plane of the paper ; the electrons emerging from the space will have been formed into a velocity spectrum. This passes between the electrodes 4, 5 and is there subjected to selective acceleration, the electrons of lower velocity being accelerated more than the others. The varying accelerating field may be obtained by forming the electrode 5 as a zigzag grid of resistance wire along which a graded potential is applied as well as a steady bias in relation to the cathode ; alternatively it may be formed of a number of separate wires connected to a potentiometer. The grids may be inclined, the primary stream - may have a preliminary smoothing out of velocity, before being formed into a spectrum. The device can be used with a grid controlled or photo-electron cathode.
