Abstract: 528,401. Gas holders. ASHMORE, BENSON, PEASE & CO., Ltd., and HUNTER, C. F. May 5, 1939, No. 13522. [Class 54] In constructing a telescopic gas holder from welded metal plates the seams on either the outside or the inside of the lifts are first welded and the holder is then inflated to allow welding on the other side of the lifts to be effected. Fig. 7 shows a gas holder in which the outer lift is first built by welding together a ring element 2, a series of plates 1, 4, 6 and a ring 8 on their inner surfaces. The inner lift is then built by welding together a ring element 22, plates 9, 11, 21 and a roof 12 on their inner surfaces. The gas holder is then inflated gradually and the seams are successively welded on the outer surface of the lifts by operators on the ring 8 or the top of the holder tank 19. When a gas holder is built from plates welded at first at the outer edges the operators are supported on a raft floating inside the holder to weld the inner edges of the plates as the holder is inflated.

Abstract: 1500993 Semi-conductor amplifiers; gain control SONY CORP 3 April 1975 [10 April 1974] 13754/75 Headings H3T and H4R A multi-purpose semi-conductor circuit for use in manual or automatic gain control, or switching or in any application in which an output of the instantaneous product of two signals is required, comprises two chains each of two series connected transistors fed in parallel via a current sink, with one signal applied differentially to the out-of-chain electrodes of the first transistors of each chain; between the intermediate points of the chains is connected a device 10 comprising three regions (Fig. 1, not shown) of semi-conductor of alternating conductivity type, each region having a terminal, the first region including a potential barrier of energy higher than that of the minority carriers injected from the second region and within their diffusion distance from the junction; the first and third regions are connected to the respective chains, the second signal being applied either to the second region of the device or in common to the out-of-chain electrodes of the second transistor in each chain. The device may also have a similar potential barrier in the third region for symmetry with the first, the impurity levels being comparable and in both regions the barrier comprising a region of high impurity level; in the first region an additional isolated region (6, Fig. 2, not shown) of opposite type may be introduced within the diffusion distance from the junction. In Fig. 3 the device 10 with first, second and third regions (NPN) connected respectively to terminals 4E, 4B, 4C, is supplied with a controlled current I 2  forming the second signal, the differential applied voltage SA forming the first. The device passes steady currents I 2 /2 symmetrically outwards, controlling the impedance of the two junctions acting as independent forward diodes, so that signal currents ai s  are subtracted from the differential chain signal currents i s , allowing "in" and antiphase signal voltages at terminals 17, 18 proportional to (1-a). The terminal B of the device may alternatively be given a fixed bias if the bias 20 is replaced by a controlled current signal source. In a second embodiment (Fig. 4, not shown) two pairs of chains, each with a device across the pair, have a first differential signal voltage applied across the bases of first transistors of the two left chains in parallel against the two right chains, a second differential signal voltage being applied to the bases of the second transistors of the first pair of chains against the second pair. Balanced output is taken from load resistors in the two inward chains in parallel and the two outward chains in parallel, proportional to the pure product of the two signals. In both embodiments the conductivity types of the devices together with all transistors may be reversed; the device, which also can act as a transistor, may be substituted for the chain transistors, or FET's may be used.

Abstract: 484,635. Treating liquids with gases. AKTIEBOLACET ROSENBLADS PATENTER. May 21. 1937, No. 14191. Convention date, May 22, 1936. [Class (ii)] In absorbing or heat-exchanging apparatus, gas, e.g. steam or vapour entering at 17 flows up a tower between concentric cylindrical or truncated conical surfaces 3 all covered with liquid films and arranged within a hollow tower beneath and adjacent a liquid distributer feeding liquid from elements 11 in rows parallel to the walls so that each element delivers without splash to a single wall surface obliquely to the upper wall end.. The walls may be of stainless steel, may be perforated, e.g. made of fine netting, may have spacing members, and Slant at different angles or are parallel but are corrugated horizontally, the corrugations having a greater pitch at the bottom than the top, so that the cross-section of the gas passages decreases towards the top. The tops of the walls 3 have tongues 12 bent out alternately to opposite sides to catch liquid from nozzles or openings 11 in an annular horizontal distributing plate 7 of a liquid reservoir , or the plate 7 may be corrugated with apertures in the sloping sides of the corrugations to deliver water obliquely to the vertical top surfaces of the walls. The top edges of the tongues 12 may extend into slots in the plate 7, which may have circular grooves round each opening for water. The walls may be oval or elliptical in cross-section, and turbulence of gas between them may be increased by gas-guiding means. The Specification as open to inspection under Sect. 91. comprises also vertical flat parallel walls hanging by shoulders thereon at the top in. a tower and covered with films of water by inclined nozzles, the gas being led off at the top immediately below a water container carrying the nozzles. In another modification, water is distributed from horizontal pipes perforated at their lower sides and placed or welded on tongues bent out alternately in opposite directions from the tops of the walls. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to variable pitch propellers
IPC: B64C11/38
Filed: 1955-05-17
Abstract: 777,400. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. May 17, 1955 [May 28, 1954], No. 14199/55. Class 114. An adjustable pitch propeller comprises a hub, blades mounted thereon, means including a movable control member for varying the blade pitch, an element fixed relatively to the hub, an element movable into engagement with the fixed element and mechanical means operatively connecting the blades with the movable control member to move the movable element into engagement with the fixed element to lock the blades against pitch change in at least one direction upon failure of the pitch varying means. Each propeller blade 14 carries a gear 16 meshing with a co-ordinating gear 18 ensuring corresponding adjustment of the pitch of all the blades. The gear 18 is splined to an annular member 140 on an elongated nut 30 which secures the propeller hub 12 on the propeller shaft 22. As the propeller rotates, a gear 74 on the rear of the hub 12 drives a gear 72 which has internal teeth for engagement with a gear 76. This gear 76 is mounted on an eccentric 80 on a shaft 82 on which the gear 72 is rotatable. Integral with the gear 76 is a gear 78 engageable with a smaller gear 90 integral with a gear 94 meshing with a gear 96 on a sleeve 98 coaxial with the propeller hub. At its forward end the sleeve 98 is formed with gears 100 and 102. The shaft 82 is turned in either direction responsive to the blade pitch control lever and advances or retards the rotation of the gears 94, 96, 100 and 102 in relation to the gear 74 which rotates at propeller speed. The relative movement thus imparted to the gear 100, through a gear 130 and a quick threaded nut 132, moves a pitch-change control valve 136, while the gear 102 operates the pitch lock mechanism through a gear 170, shaft 172 and gear 174. The gear 174 rotates a toothed ring 176 integral with a helical gear ring 178 whose teeth engage corresponding teeth on the inside of a ring 180: external teeth on the ring mesh with teeth on the annular member 140 which rotates with the co-ordinating gear 18 of the propeller blades. If movement of the pitch-change control valve 136 does not effect a pitch change and the coordinating gear 18 does not move, the helical teeth on the ring 178 urge the ring 180 to the right so that locking teeth 184 thereon engage teeth 186 on a member 188 fast on the propeller hub. When the pitch change occurs, the ring 180 travels with the ring 178 and no axial displacement occurs. The locking teeth are shaped as shown in Fig. 3 to engage fully as soon as engagement commences, the ring 178 being resiliently mounted axially to permit this. The pitch-change control valve 136 is returned to its normal position by a follow-up mechanism comprising a gear 143 meshing the annular member 140, on a shaft 144 geared to the valve 136. Specifications 688,169 and 696,658 are referred to.
