Abstract: 638,905. Sphygmographs. DEPOIT, E. J. L. Aug. 29, 1946, No. 26011. Convention date, Aug. 22, 1944. [Class 81(ii)] [Also in Groups XVIII, XIX and XXXVIII] Arterial pulsations in a chamber 1a, Fig. 1, of a pneumatic cuff 1c, are detected by a pneumatic cell 2a, converted to voltage variations by a moving coil or selenium cell device 190 and passed to a recorder 6 through a thermionic amplifier 5. The cuff preferably has a separate constricting chamber 1b and the constrictive pressure is registered by a mercury manometer 7 provided with a series of electric contacts producing signals on passage of the mercury meniscus which actuate a type wheel 8, step by step, to record the pressure opposite the corresponding part of the pulsation graph on a moving strip M marked in time intervals. By means of a uni-directional rotary control switch a motor 3a driving the air compressor 3 and strip feed is started and valves and switches operated to produce a graph 126 of pulsations under constrictive pressure rising rapidly and further rotation of the switch produces a record 127-130 of pulsations under a slowly falling constrictive pressure, and the strip is dated and severed as the switch is turned to the " stop " position. Adjustment is provided for varying the sensitivity of the pulse recording mechanism, and the apparatus can be mounted on a stand for coin-freed actuation, the cuff 1c, Fig. 3, being secured to the top of the stand and .tightened or released by a spring-loaded pull rod 15. The Specification as open to inspection under Sect. 91 comprises alternative pulsation detecting means such as variable resistances, piezo-electric crystals, variable condensers, moving armatures and hot-wire devices, and alternative magnetomotive operating arrangements for the recording device. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,270,188. Switchgear structures. S. & C. ELECTRIC CO. 29 May, 1970 [18 Sept., 1969], No. 26038/70. Heading H1W. One or more fuses 22 are mounted in a drawer 18 slidable within metallic housing 12 containing switches 35, 36, the manually operable handles 53, 54 for the switches being interlocked with a fuse drawer locking means, to prevent the withdrawal of the drawer from a switchclosed position. In the closed position of the drawer 18 the contact arms 29, 30 connected to one end of each of the three vertically stacked fuses, Fig. 4 (not shown), engage contact plates 31, 32 on which switch blades 33, 34 are mounted. The contact plates are vertically spaced along rotatable stacks of insulators (37), (38), to the upper end of which are connected operating arms 41, 42. Spring operators 47, 48 or overcentre spring operators 49, 50, see Fig. 6, provide a snap-action movement of the insulator stacks. Ground switch blades 69, 70 engage contacts 83, 84 when operated by handles 79, 80. Arc-chutes 63, 64 are provided on the stationary contact 55, 56, support plates. Handle locking links 89, 90 have longitudinally extending notches 91, 92 which if not in registry i.e. when both switches are open do not allow overlying vertically-extending drawer locking link 85 to release the drawer. Lost motion between the links 89, 90 and the handles 53, 54, enables the initial charging of the operating springs. Latch 101 is spring biased being held away from notches 91, 92 by the tip of link 85. With the drawer unlocked, the latch engages the notches so as to prevent the closing of the switches. With the switches closed the pins 113, 114 prevent, via links 109, 110, the closing of  grounding switch blades 69, 70. Further, links 121, 122 of the grounding switch prevent, in the grounded position, the closing of switches 35, 36.

Title: Improvements relating to the manufacture of composite metal products
Inventor: TURNER PHILIP GEORGE
IPC: B22D7/02
Filed: 1956-08-28
Abstract: 818,817. Making composite sheet, bar, strip and wire; casting composite ingots. WIGGIN & CO. Ltd., H. Aug. 16, 1957 [Aug. 28, 1956], No. 26290/56. Classes 83 (1) and 83 (2). In a method of making a composite metal product, e.g. sheet, strip, bar or wire, a cladding- metal is cast and allowed to stand long enough for a layer to solidify around the whole wall of the mould, the molten metal within this layer is then poured out and the cavity filled, while the cladding-layer is still plastic, by casting in a core metal, the resultant ingot being then shaped, prior to extrusion into sheet or other shape. A nickel-chromium stainless-steel is cast into a cylindrical cast-iron mould and allowed to stand for ten minutes before returning the metal which has not solidified to the furnace or ladle. Molten-iron or mild-steel is then immediately cast into the cavity defined by the layer of chilled cladding-metal. The ingot, after being fed with iron, is cropped and turned when cold to clean it and shape it to fit an extrusion container, from which it is extruded to sheet, strip, wire or bar. The coremetal may be exposed at the top of the ingot or may be totally clad by casting additional cladding-metal after completion of the core. Other cladding-metals used on an iron or mildsteel core are nickel-copper alloys, nickelchromium or nickel-chromium cobalt alloys, nickel and tool-steel. Further, a nickel-cladding may be used on a nickel-chromium-alloy core. Sheet products may be subsequently reduced by rolling, bar may be rolled to form strip, and wire may be reduced by drawing. Clad-sheet or strip may be formed into a tube, the longitudinal weld being made wholly in the cladding-metal.

The drum shaft is mounted in anti-friction bearings over a water trough 13 and is caused to rotate slowly by means of vanes 18, 19 on the spiders 5, 6 in the path of the air current from the fan. The remote end of the drum is closed, air being caused to pass outwardly through the wetted layers and thence through louvres 24 of a window opening. Means may be provided, as by hand operated gearing or by pulleys on a countershaft with a belt from the fan shaft and to the drum, to impart a positive drive at starting until the drum is completely wet.

Abstract: 151,020. Gruber, M. Sept. 15, 1919, [Convention date]. Coils and conductors.-In a slot-wound rotating field magnet for high-speed dynamo-electric machines a large cooling surface c, Fig. 2, of the conductors adjacent to the iron of the magnet is obtained by distributing the conductors over at least thirty slots per pole with from one to four conductors per slot, while the ends of the winding are embedded in metal either in the core itself or between metal segments attached thereto. The metal segments i, Fig. 4, may be of magnetic or non-magnetic metal and may be anchored in the core by dovetail enlargements. The armature core may extend beyond the field poles so that the end connexions contribute to the main field flux. The coil ends which contribute to the main field may be secured by magnetic metal segments and the remaining coil ends by non-magnetic metal segments.

Abstract: 1386729 Shift register storage INTERNATIONAL BUSINESS MACHINES CORP 4 June 1973 [3 July 1972] 26539/73 Heading G4C [Also in Division H1] One or more charge-coupled device (CCD) shift registers have first reversible sections for storing bulk data and a second, smaller, input/ output section, the first section being shiftable bi-directionally to change the order of data blocks stored therein, and the second section being shiftable at the same time for reading or writing data. Various recirculation loops 1-3 may be selectively enabled to transfer a desired block into the input/output section and to reorder the blocks in the bulk storage section, e.g. to maintain the most frequently accessed blocks nearest to the input/output section (the centre block in bulk storage may be regarded as the furthest from the input/output section). Shifting in the loops may be performed at different frequencies e.g. low frequency to conserve power, high-frequency for fast access. The devices described are 3-phase integrated semiconductor devices with regenerating FET amplifiers formed by diffusions between data block boundaries.
