Title: Highly porous active alumina
IPC: C01F7/02
Filed: 1964-11-09
Abstract: Active alumina, having not more than half the pores larger than 0.1 m is prepared from grains obtained by dehydrating alumina hydrates in a stream of hot gas.  The grains, substantially all of which have particle sizes between 1 m  and 25 m , are impregnated with water in an amount exceeding by not more than 8% the weight of water necessary to fill the pores of the alumina. They are then heated, shaped and reactivated. Alternatively a mixture of alumina with up to 30% of its weight of naphthalene or other material which decomposes on reactivation heating may be used in the initial step.  The grains may be obtained by dehydrating hydragillite. Granules, briquettes and conglomerates may be obtained by extrusion, pressing or in a groove and fillet.  A number of different pellets and briquettes of active alumina having size 2 to 5 mm., and of total porous volume 53 to 93 cc. per 100 g. including 15 to 38 c.c. of pores larger than 0.1 m are claimed per se.

Title: Superconductor strips
IPC: H01L39/14
Filed: 1966-10-17
Abstract: 1090869 Super-conductor devices SIEMENSSCHUCKERTWERKE AG 17 Oct 1966 [16 Oct 1965] 46405/66 Headings H1A A5 and A4D A composite super-conductor strip comprises a plurality of strips, each consisting of a hard superconductor coated with a normal metal, stacked parallel to one another and face to face so that the adjacent layers of normal metal are in good  electrical and thermal contact. The arrangement of a plurality of strips of super-conductor material in parallel reduces the electrical instabilities by ensuring that if part of one strip goes normal the current is diverted to the parallel strips thus reducing the current through the affected part which returns to the super-conducting state.  The hard super-conductor may be of niobiumzirconium or niobium-titanium alloy or may comprise a thin layer of niobium-tin alloy formed on the surface of a strip of niobium or between a pair of strips of niobium. The coating may be of copper, aluminium, gold or silver applied by electrolytic deposition or by rolling. The coated strips may be joined together by polishing the faces and placing in contact, which may be followed by rolling, or by coating the strips with indium and heating after stacking the strips to solder them together. Further normally conducing foils may be included between the coated strips and/or on the outside faces of the stack. A normally conductive coating may be applied to the stacked strips for example by electrolytic deposition or by winding a copper foil coated with indium round the stack and heating to solder the turns of the foil to each other and to the stack. An electrically insulating sheath, for example of polyethylene terephthalate, may be applied to the stack. The composite strip may be wound to form a coil which can be operated in the normal state at a temperature below the critical temperature of the hard super-conductor so that the superconductive state can be achieved merely by a reduction in the current.

Title: Apparatus for attaching end stops to fastener stringers
IPC: B21D55/00
Filed: 1975-11-12
Abstract: 1516859 Machinery safety devices YOSHIDA KOGYO KK 12 Nov 1975 [15 Nov 1974] 46682/75 Heading F2J [Also in Divisions B3 and E2] The full downward power stroke of a punch 10, for fitting end stops 17a to sliding (e.g. zip) fasteners 16 which have already been sewn on to articles such as trousers, is delayed until a sensor 14, which moves ahead of the punch 10, has completed a predetermined downward stroke and rests on the zip fasteners 16 on a die 12, said punch 10 being restrained from its full descent in the event that the sensor 14 fails to complete its downward stroke due to an obstruction such as the presence of an operators finger 19 &c. As shown, the punch 10 is pneumatically operated at 29, 30 via a 1st lever 23 intermediately fulcrumed at 25 on a fixed frame 20. The sensor 14 is operated by one end 33 of a 2nd lever 24 intermediately fulcrumed at 31 on the frame 20 and spring biased at 34 to maintain its other, i.e. free, end in contact with a pin 35 on the punch lever 23. The arrangement of the leverage arm ratios of the 1st and 2nd levers 23, 24 is such that downward movement of the power operated punch 10 allows the sensor 14 to move ahead of the punch 10 and descend towards the die 12 at a faster rate than the punch 10 due to the biasing spring 34 and the point of engagement of its lever 24 with the pin 35 on the punch lever 23. Only when the sensor 14 has completed its full predetermined downward movement, i.e. rests on the workpiece (zip 16), and operates a 1st limit switch 36 is the machine conditioned to allow the punch 10 to complete its working stroke, a 2nd limit switch 37 operated by the punch lever 23, subsequent to the operation of the 1st switch 36 by the sensor lever 24, permitting this full operation of the punch 10. However, if the sensor 14 is prevented from fully descending to the workpiece 16, on the die 12, by an obstruction such as the operators fingers 19 &c. its lever 24 fails to operate the 1st limit switch 36 which then conditions the 2nd limit switch 37 such that when it is engaged by the punch arm 23 it stops or reverses the pneumatic cylinder 29, 30 to stop or return the punch 10 to its upper starting point. In operation the punch 10, at the commencement of each stroke, forms each zip fastener end stop by blanking the stop 17a from a blank strip 17 fed to the punch 10 from an adjacent reel 38.

Good acoustic coupling is maintained at high rotation rates of the carrier, the coupling medium forming a stable layer of such thickness that multiple reflections between the layer and the pipe or tube do not hinder the flaw detection. To accommodate tubes of different diameter, interchangeable carriers 11 are provided. The carrier fits in a recess 14<SP>1</SP> in a rotary member 14 and is held therein by bolts or pins 18. Member 14 rotates, relative to a stator 17, on a water bearing or ball bearing.

Title: Seismic data event velocity analysis
IPC: G01V1/30
Filed: 1972-10-16
Abstract: 1399904 Seismic signal processing CONTINENTAL OIL CO 16 Oct 1972 47591/72 Heading H4D Common depth point seismic traces are processed to determine event velocities by a procedure which analyses individual events rather than fixed time windows of the traces and so avoids distortions inherent in the use of such windows. The resulting data, after editing, are displayed in an arrow head symbol format which enables event time, velocity, amplitude and polarity to be depicted. The following main steps are included in an embodiment for which a flow diagram is given (Figs. 6, 7, 10, 11, not shown): (a) The traces of one common depth point (CDP) set are given individual mutual time shifts which are each a function of the associated source-detector offset and a reference time shift (corresponding to an assumed velocity). (b) The shifted traces are composited to give a sum trace termed a 'scan". (c) Steps a and b are iterated for other CDP sets and other reference shifts. (d) The resulting scans for one CDP are reduced to "scan logs" by storing digital amplitude values relating only to the main lobes 152, 156 and their immediate side lobes (Fig. 8). (e) The tiein of events from one scan log to another is checked by comparing the scan logs in pairs. (f) The events are edited to reject those which are of low amplitude, are redundant, or do not tiein. (g) The edited scan logs are compared to determine the scan log of greatest amplitude for any given event and hence to compute the velocity of the event. (h) The scan logs are reedited to reject events for which, on the scan log of greatest amplitude, the side lobes outweigh what appears as the main lobe on other scan logs. (i) Steps d to h are iterated for other CDP's. (j) The residual events of several CDP's are tied together into horizons, using time search windows and scan search windows. (k) Average values of event time, velocity and amplitude are computed for each horizon and are assigned weights, the weighting depending on the degree of tie-in of the individual CDP data. (1) The horizons are edited to include those which lie within a given time and velocity difference from the highest-weighted horizon, or to reject certain horizons which share more than a given percentage of events with the highest-weighted horizon. (m) The residual horizons are plotted on a seismic section, in the Fig. 3A, arrow format where the vertical co-ordinate of line 32 represents event time, the horizontal co-ordinate of line 34 presents event velocity (indicated also numerically), the arrowhead size represents amplitude and the arrowhead direction indicates polarity.
