Abstract: 1492181 Detecting faults in D.C. transmission systems; HVDC transmission systems HITACHI Ltd ELECTRIC POWER DEVELOPMENT CO Ltd and TOKYO SHIBAURA ELECTRIC CO Ltd 30 Oct 1974 [2 Nov 1973] 47017/74 Headings H2K and H2F A fault detecting arrangement in a H.V.D.C. transmission system comprises a first detector LD 1  providing a signal when the current at the rectifier-end BA of the transmission line TL rises above a reference level, a second detector LD<SP>1</SP> 2  providing a signal when the current at the inverter-end BB falls below a reference level, and a coincidence circuit AND 1  providing a fault indication when the two signals occur simultaneously. Since the D.C. line may normally be worked in either direction, it is preferable to provide both a current increase and a current decrease detector at each end, two coincidence circuits, e.g. AND 1 , AND 2 , then being necessary. These coincidence circuits may be duplicated, i.e. a pair at each end, and be coupled to the opposite end via a separate transmission link. The reference levels may be fixed values. Alternatively, if the normal line current varies, each detector compares the instantaneous line current with the value of the line current a short time previously, thereby detecting only sudden changes in value.

Title: Method of separating a gas mixture by adsorption
IPC: B01D53/047
Filed: 1962-12-14
Abstract: A process for the separation of a gas mixture by means of differential rates of adsorption on a solid adsorbent comprises, introduction of a gas mixture to a first chamber containing the adsorbent under vacuum, which chamber communicates with a receiving chamber, interrupting the introduction of gas as soon as the pressure is equal between the first chamber and the receiving vessel; and isolating the adsorbent-filled vessel from the receiving vessel. Fractions of the gas mixture are then separately withdrawn from the receiving chamber and the adsorbent-filled chamber by subjecting at least the latter to a vacuum.  Fig. 1 (not shown) illustrates an arrangement in which gas passes from a first vessel 1 into subsequent vessels 2 and 3. The three vessels are then isolated by valves 4 and 5 and vacuum connections 6 and 8 serve to extract the fraction enriched in the less rapidly adsorbable gas from vessel 3 and the fraction enriched in the more adsorbable gas in vessel 2.  In Fig. 3 (not shown), a non-return valve 10 separates a vessel 2 (corresponding to vessel 2 in Fig. 1) into two compartments 11 and 12 and after carrying out the method as above, the gas is extracted from 11 and 12 by pumps 15 and 16, whereby it is possible, by varying the volume of vessel 3, to vary the volume of the argon-enriched phase, this gas being more rapidly absorbed.  By varying the position of the non-return valve 10 it is possible to obtain in the second compartment a gas fraction with the argon content close to that of the initial mixture.  After extraction this gas fraction may be re-injected into the separating apparatus thereby reducing the number of separating stages for a given enrichment. Fig. 8 (not shown) illustrates several apparatus such as used in Fig. 1, connected in counter-current cascade arrangement, the gas mixture being fed initially to the central apparatus of the cascade.  Fig. 9 (not shown) illustrates the same principle except that the individual apparatus used are of the type used in Fig. 3. Gas mixtures to be separated are air, which may be separated in three stages into O2, N2 and argon; O2 and argon.  Adsorbents used are synthetic or natural molecular zeolites such as chabazite or mordenite.  The separation of the invention may be made upon a fraction obtained by separation according to Specification 860,311 or a fraction obtained from the process of the invention may be separated according to Specification 860,311.

Title: Improvements in tension lockup apparatus for printing apparatus

Filed: 1962-12-31
Abstract: 957,661. Printing surfaces. WOOD NEWSPAPER MACHINERY CORPORATION. Dec. 31, 1962 [March 19, 1962], No. 49125/62. Heading B6C. An apparatus for securing a stereotype printing plate to a printing cylinder by plate tensioning fingers, the fingers being operated by a member which is rotatable and movable along its longitudinal axis, includes Belleville springs for exerting a predetermined minimum of pressure of the fingers independent of rotation of the operating member beyond a predetermined position. The printing cylinder 1 shown has four pairs of longitudinally adjacent printing plates P each having underside recesses 9 for receiving plate engaging fingers 5 and 7. The fingers associated with the four plates on each side of the centre of the cylinder 1 as viewed in Fig. 1 are operated from the associated cylinder and, the apparatus at each end being identical although displaced relatively by 90 degrees. The fingers 7 for one edge of the plate P as viewed in Fig. 3 on the left are fixedly mounted on a shaft 8 which is positioned by adjustment of screws 50 and 51. Similar fingers 7 for the plate edge in axial alignment with the said plate of Fig. 3 are also mounted on a shaft 8 but this shaft is adjusted by screws 50 and 51 located in the central peripheral region of the cylinder. The fingers 5 for engaging one edge of the plate as viewed in Fig. 3 to the right are attached to a hollow shaft 13 on which is mounted a gear 17 which meshes with a worm gear 21 on a member 21<SP>1</SP> rotatably mounted in thrust bearings 25, 25<SP>1</SP>. A pre-stressed Belleville spring 26 acting between a member 29 and a collar 27 urges the member 211 to the right as viewed in Fig. 3. The member has a portion on which a handle may be fitted. Rotation of the member initially causes rotation of the fingers 5 to clamp the associated plate on the cylinder but after a predetermined pressure is exerted by the fingers 5 further rotation of member 21<SP>1</SP> causes compression of the spring. The spring thus serves to take up any wear in the plate recesses engaged by the fingers and to ensure a predetermined minimum pressure being exerted by the fingers on the plate. The pre-stressing of the spring may be adjusted through actuation of a spring setting plug 30 whilst an adjustable stop 32 limits axial movement of the member 21<SP>1</SP>. Similar fingers 5 are provided on a shaft 11 for engagement in the recesses on the plate edge in axial alignment with said right-hand viewed plate of Fig. 3. An extension of the shaft 11 passes through the shaft 13 and carries a gear 15 meshing with a worm gear 19. The apparatus associated with this gear is identical to that described above with reference to the gear 21. Specification 852,167 is referred to.
