Title: Method of and Means for Surface Measurement.
Inventor: BOTTOMLEY STAFFORD CYRIL
IPC: G01B11/06
Filed: 1966-06-01
Abstract: 1,190,564. Measuring position photo-electrically. HILGER & WATTS Ltd. May 31, 1967 [June 1, 1966], No.24379/66. Heading G1A. [Also in Division G2] Light from a lamp 2 is directed by a condenser 4 through a graticule 6 carrying, e. g. a pattern of lines, to a symmetrical double prism beam splitter, from which the split beams are reflected by parallel mirrors 10 through objectives 12 to interest at a point P lying in a datum plane R. If a reflecting surface is placed in the plane R, the split beams will be reflected back along each other's incident paths to the beam splitter 8 which then directs them along an exit path axis A to an objective 18 of an eye-piece and to a photo-electric detector. If the reflecting surface lies in the plane S, a distance d from the plane R, the return paths and the exit path will be laterally displaced a distance l, directly proportional to the distance d. If the surface 5 is inclined to the plane R, the reflected split beams will produced a pair of separate images of the graticule having their lateral spacing determined by the obliquity of all surfaces. Thus the apparatus can be used for determining the distance and/or the obliquity of the reflecting surface 5 relative to the datum plane R. A refraction block 22 is provided to align the image of the graticule 6 with a graticule 16 in the eye-piece, the block being adjusted by means of a lever 24 rotated by a micrometer drum 30. A fine setting may be derived from the photo-electric cell 20.

Abstract: 697,975. Stoppering bottles. GOEMANS, E. J. Jan. 1, 1952 [Oct. 5, 1950], No. 24394/50. Class 125(ii) [Also in Groups II and XXX] A device for feeding corks or stoppers of the type having a flanged head, comprises a pair of endless conveyer bands on which the corks are delivered, the bands being spaced apart from one another a distance sufficient to receive the narrow end of the cork, and deflector means being located in the path of the bands and adapted to engage the corks to deflect them into position with their heads supported by the bands. As shown the corks pass from the feed hopper H to a slow running sorting belt 1 arranged to deliver the corks suitably spaced to a funnel F opening into an inclined shoot 1<SP>1</SP>. The lower end of the shoot is provided with a rotary drum 10 on the periphery of which are brushes 11 arranged in diagonal strips which pass one cork at a time on to the endless conveyer bands 3, 4. The spacing between the bands may be adjustable to accommodate different sizes of corks. Guide plates, 13, 14 extend along each side of the conveyer and ensure that the corks roll into position on or between the conveyer bands. A deflector 16 straddles the bands 3, 4 in the path of the oncoming corks so that they are rolled over by the flange striking the deflector and drop into position in the gap between the bands with the flange supported by the bands. The deflector. consists of a bar freely carried in slots in brackets 20, or may be a spring blade or strip of resilient material. Alternatively projections may be provided on the guide plates 13, 14. A second deflector 21 is located at the discharge end to correctly position any cork getting past the first deflector. The, conveyer bands may discharge the corks into a guide formed of two bars by which they are delivered to the bottle stoppering position B. At the delivery end one conveyer band may be arranged in a plane slightly above the other, and they may be operated at slightly different speeds. The conveyer band may be of rubber or like' resilient material, or may consist of parallel wires, belts or chains.

Title: Improvements relating to the heat-treatment of metal articles
IPC: C21D1/48
Filed: 1944-07-05
Abstract: An article formed of a ferrous metal is immersed in a bath of molten aluminium or an alloy thereof, kept at a temperature above the critical temperature of said ferrous metal so that its surface at least is heated to a temperature above its solution heat-treating temperature, e.g. between 1525 DEG  F. and 1625 DEG  F., and then is quenched.  This may be effected by immersing in oil or in a bath of aluminium or an alloy thereof kept at a temperature below the critical temperature of said ferrous metal, e.g. between 1000 DEG  F. and 1250 DEG  F.  The article may then be quenched in oil, reheated to about 1000 DEG  F., and quenched in oil again or it may be placed in a draw furnace for a suitable time and then quenched in oil.  The method may be used in making an aeroplane engine cylinder with fins of aluminium as described in Specification 599,684.

The image of the light field is.formed by tiers of lenses, Fig. 4. The first tier 13 comprises one lens, which forms an image of the whole field, the second tier 14 comprises two lenses, each of which forms an enlarged coinciding image of one half of the field, the third tier 15 comprises three lenses, each of which forms an enlarged coinciding image of one third of the field, and so on. Alternatively, the field is projected on a lightsensitive surface, Fig 8, which comprises a number of portions which are so connected electrically that they form insulated groups 1, 2, 3, each of which is connected to one transmitting channel. The portions are connected in rows. The first comprises one set of portions from each of the groups, the second row comprises two such sets, the third row three, and so on. At the receiver, each of a number of juxtaposed light sources is controlled by signals from the corresponding channel to produce, by means of tiers of lenses, a moving light field corresponding to that at the transmitter. The light is projected on a screen through scanning apertures equal in number to those at the transmitter. The scanning- apparatus is similar to that described in Specification 379,303. Specification 403,395 also is referred to.

Abstract: 870,735. Water-tube steam boilers; superheaters. BABCOCK & WILCOX Ltd. July 29, 1959 [Aug. 1, 1958], No. 24949/58. Classes 123(2) and 123(3) In a forced flow steam boiler of the kind having circuits connected in parallel for the flow of the working medium and an upright furnace chamber space lined by tube lengths of the circuits, equal heating of the circuits is ensured by dividing the furnaces space into a number of zones one above the other each occupied by a lining tube section, each section comprising horizontal tube lengths of the different circuits. The arrangement of tubes is shown diagrammatically in Fig. 1 wherein a furnace chamber 1 is lined with horizontal tubes 2, the lining comprising two sections 5A, 5B. Four circuits constituted by two pairs of tubes 3, 3' and 4, 4<SP>1</SP> are shown extending from a distribution header 6. The tubes 3, 3<SP>1</SP> enter the furnace chamber through a wall 7 and then pass is one direction around one half of the chamber as part of the lining section 5A to leave the chamber through the opposite wall 10. The tubes 3, 3<SP>1</SP> are then continued upwardly as tubes 8, 9 and re-enter the chamber through the wall 10 wherein they pass around one half of the chamber as part of the lining section 5B to leave through the wall 7. The tubes 4. 4<SP>1</SP> line the opposite halves of the chamber in both the sections 5A, 5B. The complete lining of tubes arranged in this manner may have any suitable number of circuits and sections. For example, in Fig. 3, not shown, the lining has 128 circuits and 14 sections. The tubes 2 of each section of the wall lining are welded together so that each section is rigid unit of box girder like form. Each section of the wall lining is supported by suspension from vertical buckstays 50. Fig. 4, gas tight expansion joints, Fig. 6, being provided between adjacent sections. The buckstays 50 which are supported against outward movement by horizontal buckstays 51' present rows of hinge-like connectors 53 to which are welded the upper tubes of respective sections, the sections thus being able to expand and contract independently of one another. The setting has an external gastight casing of metal plates 60, 61, whilst the tube bundles passing upwardly from one section to the next are packed around with insulation 62. The expansion gap 48, Fig. 6, between adjacent sections 41, 42 is sealed by a gastight expansion bellows 100 which is built in between adjacent positions of the insulating wall 63A...63D of the unit. In a modification a natural circulation boiler having a furnace lined with vertical generating tubes has a superposed radiation space lined with horizontal superheater tubes arranged as described above.
