Title: Magnetic and ferroelectric counting and registering devices
IPC: G11C19/04
Filed: 1956-04-17
Abstract: 817,764. Pattern-movement stepping registers; electronic counting-apparatus. RADIO CORPORATION OF AMERICA. April 17, 1956 [April 28, 1955], No. 11718/56. Class 106 (1). [Also in Group XXXIX] A stage of a counter or of a shift register comprises two binary storage elements linked by a transfer winding, one element being magnetic and the other ferro-electric. A series of magnetic elements 1M-5M, Fig. 1, and a series of ferro-electric elements 1E-4E are connected respectively to sources 24, 29 of shift pulses 32 (positive) and 34 (negative). Normally, the elements are all in a negative condition N into which the shift pulses tend to drive the elements. A binary one is written into magnetic element 1 by a pulse 36 from source 30 which changes the element to the P condition. The binary one is shifted from one element 1M to the next 2M in two steps by pulses 32, 34. The first pulse 32 transfers the P condition from 1M to 1E and the second pulse transfers it to 2M. The condition of each magnetic element can be indicated by a load L. The register returns to normal when the binary one is read out from the last magnetic element 5M. A ring counter may be formed by coupling magnetic elements 5M and 1M by output winding 16 and a fifth ferroelectric element. The ring counter is reset to normal by means of reset windings (not shown). If the elements are normally all in N condition (or all in P condition) the information can be shifted from left to right by shift pulses of opposite polarity 32, 34 (or 37, 38). If, normally, all the magnetic elements are in one condition N (or P) and the ferro-electric elements are in the opposite condition P (or N) the information can be shifted from right to left by pulses of the same polarity 32, 38 (or 37, 34). Certain patterns can be shifted unchanged in the register shown in Fig. 1. Any pattern can be shifted unchanged in the register shown in Fig. 5. The magnetic elements 1M-5M are linked as before but odd elements are connected to pulse sources 52, 56 and even elements to sources 54, 58, pulses being produced in the order 52, 56, 54, 58. The load L may be connected to the transfer links instead of to separate windings.

Title: Improvements in or relating to the electrolytic treatment of metals
Inventor: PULLEN ALFRED NORMAN DOUGLAS
IPC: C25D11/04
Filed: 1951-05-21
Abstract: 770,950. Electrolysis. BRITISH ALUMINIUM CO., Ltd. May 14, 1952 [May 21, 1951; July 4, 1951], Nos. 11849/51 and 15903/51. Class 41. A method for the continuous treatment of long, flexible metal articles 5, having current-conducting parts of small cross-section comprises advancing the article 5 through an electrolyte in which are at least partly immersed electrodes connected to the opposite poles of an electric current-supply source, the article passing in a path spaced from the electrodes, the electrolyte comprising a main volume. e.g. in a tank 10, and a volume in a chamber 19, the volumes being in communication with each other by at least two constricted passages 20 through which the article 5 is sequentially advanced from the main volume into the chamber 19, which contains an electrode 23 connected to the supply source, and back into the main volume. The invention is particularly applicable to the anodizing of sliding clasp fasteners wherein fastener elements of aluminium are clamped to the beaded edge of a textile braid having one or more fine wires therein for electric interconnection of the elements. In the apparatus shown the strip 5 before entering the main cell passes between carbon electrodes 14 in a chamber 8 supplied at 16 with electrolyte, which overflows into the main cell at 17. Guides for the strip are provided at 12a, 12b, the latter being constricted. The strip thereafter passes back and forth over pulleys 9a, 9b, 9c, 9d to an exit pulley 9e, passing midway in each stretch through the apertures 20 in the chamber 19 and between electrodes 23; the chamber 19 is supplied at 21 with electrolyte which overflows at 22. Current passes from the lengths of strip outside the chambers 8, 19 to a counter-electrode not shown. The electrodes in chamber 8 are connected to the supply terminal 27 through a resistance 25 to limit surge of current as the strip enters the electrolyte ; the electrodes in chamber 19 are directly connected to the terminal. The electrodes in chamber 8 may be dispensed with, the chamber then serving only for pre-wetting of the strip. Direct or alternating current may be used for anodization. A similar arrangement of parts to those described may be arranged parallel to the first in the same cell for passage of a second strip. In this case when using alternating current, separate counter-electrodes may be dispensed with the two strips being connected as opposite poles. By making the length of strip between successive passages through the supply device sufficiently short the effect of electrical discontinuities in the material is reduced. Provisional Specification 11849/57 describes an apparatus in which some of the pulleys round which the strip passes are located in the chamber, including the electrodes whereby electric contact is established. Specification 599,188 is referred to.

Patent GB-788404-A (GB)
Title: Gas recovery process
Inventor: COPPOCK PHILIP DALTON
IPC: C01B32/50
Filed: 1955-04-26
Abstract: Carbon dioxide is separated from a gaseous mixture by absorbing into an aqueous solution of an ethanolamine at atmospheric or higher pressure followed by desorption of the carbon dioxide from solution at a pressure below atmospheric.  The absorption pressure is preferably 1-6 atmospheres and the desorption pressure preferably 500-30 mm. mercury absolute.  The ethanolamine solution is preferably of 2-4 molar concentration and may also contain potassium carbonate. Gases which may be treated are flue gases and gases obtained from fermentation processes or lime kilns.  The gas mixture may be given a preliminary treatment with dilute alkali to remove dust and sulphur dioxide and to cool the gas.  Absorption and desorption may take place in towers packed with coke, the gas from the desorber being compressed and passed in heat exchange with the desorbed solution which is then recycled to the absorber. Examples describe the treatment of gases containing 10-60 per cent carbon dioxide with solutions of monoethanolamine, diethanolamine, and triethanolamine. The Provisional Specification refers to the removal of hydrogen sulphide from gas mixtures by a similar process.

Title: Improvements in or relating to positive clutches
IPC: F16D23/08
Filed: 1927-05-04
Abstract: 294,301. Carling, W. T. May 4, 1927. Clutches, claw.-In means for preventing inopportune engagement of positive clutches, comprising a locking- element having limited angular displacement in either direction relatively to one clutch member and continuous frictional engagement with the other clutch member or part rotated thereby, as described in Specification 282,121, the locking-element and second clutch member are thrown into slight intermittent torque-engagement on commencement of the clutch-engaging operation. In constantmesh variable speed gearing, the driving and driven members 3, 6, Fig. 1, have peripherallytoothed clutch parts 4, 5, and the displaceable locking-element 7, in slight frictional engagement with the member 3 and retained thereon by a flange 9, has fingers 10, passing through arcuate slots 11 in the member 6, and domes 12 adapted intermittently to engage depressions 13 under the engaging-pressure of the shifting-lever acting through member 6 on shoulders 14 of the fingers 10. As the originally-slower member begins to run relatively faster, the element 7 is displaced and the shoulders 14 slip through the slots 11, the parts 12, 13 being so located that the clutch teeth are then in register. Fig. 5 shows a modification, in which a cam 19 on the rod 20 carrying the clutch fork 21 acts through a spring 18, arm 15, and ring 9<a> slidably connected to the member 3, to apply independent pressure to the locking-element 7 before the member 6 contacts with the shoulders 14, a spring 22 withdrawing the arm when the clutch is engaged. The shift.- ing-lever (Fig. 7, not shown) may act on its shaft through buffer springs to absorb vibration due to engagement of the parts 12, 13. The domes 12 may be replaced by spring-pressed radial pins 12<a>, Fig. 8, adapted to be brought into intermittent engagement with recesses 13<a> in the member 3. The Provisional Specification describes the use of one or a few domes and recesses on the members 3, 6 respectively, which members are spring-pressed apart, and also forms in which a dome on the member 3 engages a small friction disc flush with the face of the element 7, and in which a rib on the free end of a spring carried by the element 7 is pressed radially into a notch in the member 3. In a form somewhat as shown in Fig. 5, the arm 15 contacts with a coned rear face of the element 7. The element 7 may normally rotate with the non-sliding member 3.
