Title: Floating structure stabilizers
Inventor: GOODRICH GEOFFREY JOHN
IPC: B63B39/03
Filed: 1965-01-29
Abstract: 1,125,961. Stabilizing ships. NATIONAL RESEARCH DEVELOPMENT CORP. 31 Jan., 1966 [29 Jan., 1965; 6 Aug., 1965], Nos. 4170/65 and 33791/65. Heading B7M. In a passive stabilizing system for a ship, floating drilling platform or floating aerodrome, a rectangular tank 1 partially filled with liquid 2 has a horizontal divider 3 located centrally below the static liquid level and extending completely across the tank in the direction parallel to the axis of roll the length of the horizontal divider 3 being 40 to 60% of the length of the tank. The free ends of the divider are shaped to facilitate flow and during oscillations about the axis of roll liquid flows beneath and over the divider at different mass rates. The system may be used to reduce pitching of any floating structure when the ratio of length to beam is such that a stabilizing system for pitching motion is feasible.

Title: Improvements in and relating to tap changing switches provided with bridging resistances for regulating transformers
IPC: H01F29/04
Filed: 1955-02-11
Abstract: 798,870. Transformers. SMIT & CO.'S TRANSFORMATORENFABRIEK N.V., W. Feb. 11, 1955 [Feb. 22, 1954], No. 4206/55. Class 38 (2). [Also in Group XXXVII] An on load tap changing switch for changing the connection of line 59 to taps 23-28 of transformer 22 comprises in concentric arrangement, fixed contacts 29-34 connected to the taps, a first rotatable cylinder carrying two groups of contacts 38-45 and 46-53 respectively to taps on resistors 55, 56, contacts 38, 46 being connected to selector contacts 36, 37; and an inner rotatable cylinder carrying contacts 54. To change the connection from tap 23 to tap 24 the cylinders are rotated in the directions shown by the arrows. Connection between contacts 54 and 36 is first broken, line 59 remaining connected to tapping 23 through 54, 46, 37, 29 and through 54, 45, resistance 55, 36, 29. Contact 36 then leaves 29, and line 59 is connected to tapping 23 only through 54, 47, resistance 56, 37 and 29. On further rotation contact 36 engages 30, when the resistances between 54 and 36 and between 54 and 37 have been respectively reduced and increased by about one-third. Thus the rotation decreases the amount of resistance 55 and increases the amount of resistance 56 connected across tappings 23, 24. Finally line 59 is directly connected to tapping 24 through contacts 54 and 36, 37 which engage segment 30. The arc lengths of 29-34, 38 and 46 may be altered so that the selector switch operates under no-load. In modifications the contacts may be divided into two coaxial, axially displaced groups, Fig. 3 (not shown), or the change-over switch contacts may be divided into two diametrically opposite pairs and the resistors 55, 56 with associated contacts may be arranged on opposite halves of the periphery, Fig. 4 (not shown).

Title: Method of manufacturing semiconductor devices in which a layer of semiconductor material is provided on a substrate apparatus for use in carrying out said method and semiconductor devices thus manufactured
IPC: C01B33/02
Filed: 1976-02-04
Abstract: 1498925 Semiconductor crystal growth on a substrate PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Feb 1976 [7 Feb 1975 26 Sept 1975] 04367/76 Heading B1 A layer of semiconductor material is grown on a main surface of a solid substrate by solidification of molten semiconductor material on the substrate surface. Suitable apparatus, as shown in Fig. I, comprises a metal chamber 1 containing a body 4 of polycrystalline silicon which forms a support for a liquid mass 5 of molten silicon formed at the upper end 6 of the support 4 by induction coil 7. Disposed on either side of the support 4 are substrates in the form of strips 10 and 11 which are guided by rollers 12 and moved in the direction of arrows F. As a result of the close proximity of the strips 10 and 11, made from a material which can be wetted by silicon e.g. carbon fibre, the silicon of the mass 5 will wet the strips. The liquid silicon retained by the substrate strips 10 and 11 is driven in the direction of arrows F by movement of the strips 10 and 11 and crystallises in the form of layers 17 and 18 as the silicon is moved away from the induction coil heater 7. Silicon layers are thus continuously obtained on the strips and collected outside the chamber 1. Silicon strips can be obtained by this method having a thickness of about 60 Ám, a width of 2 cms and a length of several centimetres. Inclination of the strip-shaped substrates, relative to a vertical direction so that the two strips approach each other, results in the growth of thicker layers.

C., 24, Elmhurst Avenue, Highland Park, Detroit, Michigan, HOPKINS, H. S., 96, Bradford Avenue, and HOVER, J. M., 1551, Cumberland Street, both in Crafton, Pennsylvania, both in U.S.A. Feb. 10, 1930, No. 4415. Convention date, Feb. 13, 1929. [Class 51 (ii).] Metal or other sheets 5 are fed from rollers 8 of a furnace on to a conveyer 16 comprising side chains 17 with spaced cross bars 18, the conveyer carrying each individual sheet until its leading edge comes against a stop 35, the conveyer continuing to move forward so that first the back edge of the sheet sags down between the cross bars of the conveyer and drops on to the pile of sheets on the truck 38 while on its continued movement the conveyer frees itself from the sheet and allows it to drop or is laid down gradually on the pile, the cross-bars 18 which are provided with loose rollers 19 also assisting positively by depressing the sheet on to the pile. When one pile is complete and the truck is being lowered on hydraulic jacks 40 to be wheeled away the first stops 35 are lifted out of the way but the sheets are still continuously fed until they come against other stops 35', where another pile is formed similarly. The two piling stations therefore allow continuous working and feed from the annealing furnaces. The stops 35 may be adjusted to suit sheets of different lengths. Two sets of sheets may be fed side by side from two piles on one truck.

Abstract: 843,521. Poultry batteries ; animal feeding and drinking appliances. GROSSMITH, N. Feb. 12, 1959 [Feb. 17, 1958], No. 5063/58. Class 5(2). The frame of each tier of a poultry battery, comprising cages arranged back-to-back, consists of central, horizontal members 10 and 18 spaced apart by vertical posts 11, inclined crossspars 12 secured to the posts 11 and to the member 10, and vertical struts 13 secured adjacent the outer ends of the cross-spars. Every alternate strut 13 extends below the cross-spars to form legs for supporting the tier. The upper ends of the members 11 and 13 support a framework 15 on which may be placed a wire netting roof, or the droppings board 17 of the tier above, the latter of which may be as described in Specification 843,522. The tier is separated into cages by wire mesh partitions, and mesh doors to each cage are hinged along their upper edges to the frame members 16. Gaps are left between the wire mesh and some of the frame members to facilitate cleaning the battery. Wire mesh is also extended beneath the cross-spars 12 to form the flooring of the tier, both the spars and netting being extended beyond the cage to form an egg-collecting trough, the eggs being collected against wires 19 fixed to the spars, and flaps 23 being provided for preventing the hens from gaining access to the eggs. Feeding troughs 20, (for example of the kind described in Specification 843,523), and drinking troughs 21 are supported across the exterior of the cage doors, thereby preventing the latter from swinging outwardly. The drinking troughs, which each extend for the full length of the tier, may be in communication at one end with a common supply tank, and at the other communicate with a common, vertical header pipe leading to a drain, the troughs entering the header pipe in staggered formation so that the overflow from one trough does not flow into another. Each feeding trough 20 is of sufficient length to serve two cages, and is held in place by lugs engaging behind rails 22, and by the engagement of its top edge in slots formed between blocks 24 and vertical struts 14 (not shown). The troughs can thereby be moved parallel with the fronts of the cages.
