Title: Improvements in or relating to methods of and devices for measuring surface roughness
IPC: G01B11/30
Filed: 1966-04-05
Abstract: 1,109,034. Determining surface roughness optically. EDNALITE CORPORATION. April 5, 1966 [April 9, 1965 No. 15044/66. Heading G1M. [Also in Division G2] A method of measuring the roughness of a surface comprises viewing targets along a fixed line of sight by reflection at the surface under investigation, at an angle of incidence greater than 45, said targets being constituted by spaced lines of different size, thickness and spacing having correspondence to varying degrees of surface roughness, and selecting that target constituted by the smallest, thinnest and closest lines that can be clearly resolved as an image after reflection at said surface, which selected target indicates the surface roughness. A plurality of targets are provided on a single plate 10 which may be rectangular or circular. This plate 10 is slidably or rotatably mounted to bring a selected target into a beam of light incident on the surface S under investigation.

Title: Improvements relating to machines for filling vessels such as bottles with liquid
Inventor: FOX DOUGLAS PERCY SHOOLBRED
IPC: B67C3/12
Filed: 1952-06-16
Abstract: 732,240. Bottling. VICKERS-ARMSTRONGS, Ltd. May 19, 1953 [June 16, 1952], No. 15128/52. Class 125 (2). In counterpressure rotating-table filling machines wherein each filling head includes a liquid valve 23 at the bottom of the filling tube 13 and a counterpressure valve 37 within the filling head casing 12, these valves being moved vertically in appropriate sequence through push rods 27, 38 by a tappet plate 31 rotated about a vertical axis by a star wheel 51 engaged by stationary stops around the machine, vertical movement of the plate 31 being effected by screw threads 48, each valve has a safety ball valve in series with it to close automatically upon a surge of liquid or counterpressure. Alternatively, the plate 31 may have its operative surface 30 formed as a face cam. The machine may be of the annular tank type. As shown, however, a pipe 7 leads liquid from a central reservoir to each head into which the liquid enters through a chamber 32, port 35 and chamber 11 communicating with the filling tube 13. A rush of liquid due to e.g. a burst bottle causes a phosphor bronze ball 33 to close the port 35. Closing of liquid valve 23 at the end of a cycle causes a collar 36 on stem 27 to knock the ball 33 out of seating 35. Counterpressure from a central water-column levelling vessel is transmitted through pipes 10 to a chamber 43 in each head. Thence, it passes through a port 42, a valve chamber 14 and conduits 15, 16 and 22 to the bottle. Valve 37 is at the lower end of chamber 42 and a ball 44 closes the port 42 in the event of a rush of gas. A shoulder 46 is so disposed on the rod 38 that the ball is knocked out of the port when the valve 37 is in its half open position or as it is moved from fully open to closed position. The valves are closed by springs 25, 41. In operation, the bottle is raised to engage member 20 which rises to cause gasket 18<SP>1</SP> to seat against gasket 17<SP>1</SP>. Star-wheel 51 is actuated to move valve 37 to half-open position to supply counterpressure. On further actuation of star-wheel 51, valve 37 is fully opened and the liquid valve 23 is also opened. The star-wheel is then, after filling, restored to its original position to allow the valves to close and the filled bottle is lowered. Specifications 503,927, 600,359 and 722,358 are referred to.

Title: Preparation of electrically conducting boron nitride
IPC: C30B1/12
Filed: 1962-04-24
Abstract: N-type electrically conducting cubic boron nitride is made by heating at at least 1200 DEG  C. and at least 42000 atmos. in the presence of a catalyst and a minor amount of Si and/or Ge, a source of boron and a source of nitrogen. The source of boron can be B, hexagonal BN, or B compounds that decompose to elemental B under reaction conditions. The source of N can be hexagonal BN or a nitride of the catalyst metal.  The catalyst may be alkali metals, alkaline earth metals (including magnesium), Pb, Sb or Sn, or their nitrides.  0.001 to 10% or more by weight based on BN of the Si or Ge additive is used.  The electrical resistivity of the cubic BN is 1 x 103 to 6 x 105 ohm./cm. The catalyst may be as a powder, or as a tube into which hexagonal BN and additive are introduced.  Ti, Ta, pyrophyllite or carbon tubes may also be used.  Preferably 0.1 to 1 part catalyst, e.g. Li3N, is used per part hexagonal BN.  The matrix containing cubic BN is dissolved in hydrochloric acid or aqua regia...  The cubic BN is separated from the hexagonal form by hand or by flotation.  N-type BN is prepared by the above method; if p-type BN, similarly prepared but using Be as additive instead of Si or Ge, is mixed with the ingredients described above, rectifying cubic BN crystals containing a p-n junction are produced.  The n-type BN may be used as transistors, rectifiers, thermometers, electro-luminescent bodies, or high energy particle counters, or as catalyst for oxidation or recombination reactions.  A combination of n and p-type crystals may be used in computer memory systems. Specifications 830,210, 860,499 and 973,822 are referred to.

Title: A process for polymerizing an alpha olefin monomer
IPC: B01J19/18
Filed: 1965-04-13
Abstract: In the preparation of alpha-olefin polymers, e.g. block copolymers, contamination of unreacted monomer and, if present, any normally gaseous diluent, recovered from the polymerizate, by a volatile compound or compounds which are subsequently used to treat the polymer after the separation of the monomer and diluent, is prevented by passing the separated polymer through a transfer zone, and at the same time passing a sweep gas through the transfer zone in the direction of movement of the separated polymer.  The sweep gas is any normally gaseous material which is inert to the main polymerization system such as argon or nitrogen, a similar monomer, or propane or butane.  The alpha-olefin polymers are prepared using a Ziegler-Matta type catalyst, e.g. TiCl3 activated with (C2H5)3Al or (C2H5)2AlCl and the polymerization effected either in bulk, or in a gaseous diluent. Hydrogen may be present. Specified alpha olefins are ethylene, propylene, butene-1, pentene-1, 3-methyl-butene-1, and 4-methyl-pentene-1.  The volatiles which may contaminate may be an alcohol, or a gaseous monomer or diluent which may be used in a subsequent block polymerization step.  The Specification includes a flow diagram of a suitable arrangement of apparatus for carrying out a continuous polymerization process including means for avoiding contamination of flashed monomer and/or gaseous diluent.  In the example, propylene is bulk polymerized and the subsequent active polypropylene block polymerized with ethylene.

Abstract: 1470479 Data processing WALT DISNEY PRODUCTIONS 17 April 1975 15872/75 Heading G4A Selected data units are read from storage, by entry of identification signals which have also been stored in association with the data units, and written into a first storage area of a core store, from which they are transferred to a second storage area of the core store and stored in association with different identification signals. This may be used in a system for generating signals to control an animated figure, the identification signals for each data unit identifying the appropriate "show", one or more animation channels, and timing signals; data units may then be moved, relative to the timing signals, within a "show" to achieve correct synchronization with, for example, audio signals, or data units from a previous "show" may be used as part of a desired "show". To enter new animation data a console 2020 is used. Keys 2035 are used to enter an address identifying an animation channel and control signals are generated for this channel either by a switch 2030, for example to control lights, or by a potentiometer 2025 to control a part of the animated figure, timing signals being generated by clock circuit 2065 either in response to discrete signals from keys 2075 or by counting in response to an initial signal from keys 2075. The entered address, control and timing signals are stored in a disc storage unit 2200. When sufficient data has been stored in the disc storage unit 2200 it is read out and sorted, by computer 2100, together with data previously stored in a tape or disc unit 2500, in terms of the timing signals, and stored in the tape or disc unit 2500. When the data for a complete "show" has been stored in tape or dies unit 2500 it is read out to computer 2100 where it is compressed by the removal of constant data and stored, together with a directory track, on a disc storage unit 2600. The resulting disc controls the animated figure via a demultiplexer 2700 in synchronism with timing signals generated internally or externally from a tape carrying audio and synchronizing signals or in response to movement of a vehicle through an animated display area.

Abstract: 318,293. Coates, H. June 2, 1928. Systems for alternating-current motors only.- All phases of a supply to a motor are arranged to be cut-out upon failure of any phase. The supply is to terminals 11, and thence through main switch 14, overload coils 15, contactor 16 and relay coils 21 to the stator. Closure of selector 38 for manual control or through float switch 35 for automatic control, causes coil 20 to be energized over contacts 115, 117 and 48. As soon as relays 21 are energized, contacts 41 close in parallel to contact 117, so that when contact 117 opens due to operation of the rotor resistance 17 under the action of an operating coil 18 and restraining coil 19, the circuit of coil 20 is maintained. Failure of current in any phase causes corresponding relay contact 41 to open and con. tact 42 to close. Closure of anv contact 42 energizes relay 36 over contacts 53. Relay 36 then closes contacts 47 to maintain itself and open contacts 48 to de-energize coil 20 and open contactor 16. Contacts 53 have a time delay in closing so as to prevent inadvertent operation of the relay 36 on starting the motor.
