Title: Improvements in or relating to laminated board structures
IPC: D21H11/04
Filed: 1955-02-08
Abstract: 801,388. Laminates. KOPPERS CO., Inc. Feb. 8, 1955 [Feb. 17, 1954], No. 3773/55. Class 140. A laminated board structure consists of two flexible sheets having interposed therebetween and affixed thereto a cellular structure of a density in the range of 2 to 12 pounds per cubic foot, such structure having been produced by the expansion of polystyrene beads containing, for each 100 parts by weight, 5-30 parts by weight of an aliphatic hydrocarbon boiling in the temperature range 35‹ to 60‹ C. Specified flexible sheets are Kraft paper, sheets of regenerated cellulose, polyethylene or vinyl resins such as polyvinyl chloride or vinylidene chloride resin, aluminium foil, jute paper board, chip paper board, manila paper board, straw board or textile material. The opposed surfaces of the flexible sheets may be coated with adhesive or alternatively adhesive may be coated on or admixed with the expandable polystyrene beads before the latter are interposed between the sheets. Specified adhesives are starch adhesive, polyvinyl acetate, polyvinyl chloride, starch adhesive modified with urea-formaldehyde resin, sodium silicate, polyvinyl alcohol, asphalt or polystyrene latices. In an illustrated embodiment sheets of Kraft paper 10 and 11, drawn from rolls 12 and 13, pass over applicators 14 and 15, whereby starch adhesive is applied to the opposed surfaces thereof. The sheets then pass over rollers 16 and 17 and enter the heating zone 18. Expandable polystyrene beads 23 are disposed between the sheets by disposing means 19 and doctor blade 20. After leaving the heating zone the sheets, with the expanded cellular polystyrene 24 disposed between them may optionally pass between rollers 21 to compress the board structure to a desired thickness. Thereafter the board passes through a cooling zone 22. The board may be used for the construction of shipping containers.

Title: Improvements in or relating to the contacting of liquids with comminuted solid refining agents
IPC: C10G25/06
Filed: 1952-02-13
Abstract: <PICT:0728056/III/1> Liquids are contacted with comminuted solid refining agents by establishing a column of the refining agent, introducing a gaseous medium into the column to fluidize the refining agent so that it has a uniform apparent density, discharging refining agent from a lower part of the column to a transfer line and through the latter to a contact tank by the injection of a gaseous medium into the transfer line at a constant rate of flow, varying the rate of flow of refining agent into the transfer line in response to variation in the pressure drop in the transfer line so that the refining agent enters the contact tank at a constant rate of flow, and independently discharging into the contact tank a proportioned flow of the liquid.  The comminuted refining agent may be of natural or synthetic origin and the amount employed may depend on the absorptive, adsorptive, catalytic or chemical properties of the refining agent.  The refining agent may be aluminium chloride, a filtering agent, or a clay such as montmorillonite, Fullers earth or bauxite.  The process is particularly applicable to the treatment of fatty acids, petroleum waxes and mineral lubricating oils with clay in order to remove colour bodies, unstable or malodorous components, or other contaminants.  In the drawing, clay from storage bin 24 passes through discharge leg 26 and transfer line 30a to contact tank 10, while mineral lubricating oil enters tank 10 through line 12. The clay in discharge leg 26 is fluidized by air introduced through valves 44 and 46, while differential pressure indicator 50 is used to show any changes of density of the clay mass in discharge leg 26 and to aid in establishing the desired constant density.  A constant flow of steam is introduced into line 30a through line 30, but clay flow through valve 28 into line 30a is influenced by differential pressure controller 40 to ensure a constant flow of clay into tank 10.  The clay enters tank 10 through a beaded chamber formed by baffle 62, this chamber containing flow-interrupting baffles 64. Inert gas or steam may be introduced into tank 10 through line 17 to aid in agitating the mixture and, if necessary, to remove light ends of the oil.  Water vapour leaves tank 10 through line 56 while clay-oil slurry leaves through line 68.

Title: Improvements in or relating to microwave amplifying devices
IPC: H01J25/60
Filed: 1952-02-14
Abstract: 695,187. High-frequency discharge apparatus. PATELHOLD PATENTVERWERTUNGS & ELEKTRO-HOLDING AKT.-GES. Feb. 14, 1952 [Feb. 16, 1951], No. 3956/52. Class 39(i) An amplifier tube has a plurality of resonators Rl, R2, R3, of the general kind shown in Fig. 1, spaced opposite a guide electrode L. Electrons from one or more cathodes K are diverted cycloidally by transverse magnetic field N to move between the resonators and the guide to collector M. Each resonator has its wall facing the guide divided by a zig-zag slot into segments C1, C2 connected to the opposite walls between which the electric vector E is developed. The time of flight between segments being a half-cycle, the velocitymodulation effect on the beam is cumulative at each segment, and if the resonator is long enough may provide positive feedback and self-oscillation. Resonator R1 receives an input from lines P1 (to a loop for magnetic coupling, or to successive segments for electric coupling). Resonator R2 provides cascade amplification. Resonator R3 feeds output lines P2. In a modification, Fig. 6 (not shown), the whole may be bent into hoop form so that cathode and collector are adjacent. Guide electrode 2 may be a squashed helix to provide extra wave impedance. Band width may be increased by tuning successive resonators slightly above and below the mean frequency and coupling them electrically or magnetically.

Title: Method for forming layers of predetermined thickness
IPC: H01L23/29
Filed: 1972-01-28
Abstract: 1380165 Removal of material by sputtering INTERNATIONAL BUSINESS MACHINES CORP 28 Jan 1972 [19 March 1971] 4052/72 Heading B3V [Also in Division C7] A layer of predetermined thickness is produced on a substrate by simultaneously reacting a reactive constituent with the material of the substrate to produce a layer thereon and removing material of the layer from the substrate by sputtering, the rates at which the layer is produced and at which material is removed from the layer being such that an equilibrium condition exists at a predetermined thickness where said rates are eqaul. For example, in reactive sputtering a layer of oxide, nitride, or sulphide may be formed on a metal or semiconductor substrate, the layer being sputteretched as it forms so that when the diffusionlimited coating formation rate falls to become equal to the sputter etch rate (which is constant under constant conditions) the coating thickness becomes constant regardless of processing time. The substrates may be sputter-etched in Ar prior to processing; reactive gases mentioned are H 2 , N 3 , O 2 , H 2 S and CH 4 . In the fabrication of a Josephson tunnelling device, a 6000  coating of Nb is RF sputtered on to glass at 670 K. and this coating is oxidized by lowpower RF glow discharge in O 2 , parameters such as temperature, pressure, and ion energy being varied to give the desired etch-sputter rate and equilibrium coating thickness. A counter-electrode of Pb is then evaporated on to the Nb oxide barrier.

Abstract: 1,101,107. Blasting. WHEELABRATOR CORPORATION. 1 Feb., 1966 [1 Feb., 1965], No. 4480/66. Heading B3D. The edges 28, 29 of a throwing blade 25 are received in radial grooves 31 in parallel side plates 12 of a wheel. Abutments 34, 35, 36, 37 are provided on the back face 33 of the blade. A locking member 39 has its ends 40, 41 engaged in recesses 42 in the side plates. A central portion 38 is eccentric with respect to the ends 40, 41; when the member 39 is rotated to locking position (Fig. 4), the portion 38 lies between the abutments so preventing inward or outward movement of the blade; when the member 39 is rotated to release position (Fig. 5), the portion 38 is higher than the projections 35, 37 so permitting outward withdrawal of the blade. An actuating arm 43 is acted on by centrifugal force to maintain the locking member 39 in locking position. A spring 44 located in an axial hole in one end of the locking member restrains against actuation by gravity acting on the arm 43 when the wheel is stationary. Cylindrical or cam-shaped portions 46, 47 bear on the blade when the member 39 is in locking position, thus controlling the degree of looseness of the blades in the grooves. One of the abutments 35, 37 may be omitted. The height of the abutments 34, 36 is such that they co-operate with the portion 38 when the member 39 is in release position so limiting the inward movement of the blade when it is inserted. The abutments 34, 36 may be omitted, the inner abutments 35, 37 being disposed to contact the spacers between the side plates.
