Title: Improvements in or relating to semi-conductive devices
IPC: H01L23/42
Filed: 1958-02-28
Abstract: 874,801. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 28, 1958 [March 4, 1957], No. 6548/58. Class 37. A semi-conductor device comprises a semi-conductor body containing a rectifying junction and provided with at least two contacts which is embedded in a good heatconducting mixture of an insulating binder and crystalline silicon carbide. In the embodiment a transistor 1 attached to conductors 2 sealed through a glass lid 3 is placed in a viscous mixture, consisting of 40 c.c. of a polymerized methyl siloxane and 60 grams of crystalline silicon carbide, contained in glass tube 4. The lid is then sealed to the tube and the viscous mixture compacted by centrifuging. Since silicon carbide is not an insulator the transistor and associated conductors are coated with a thin layer of insulating lacquer prior to their insertion in the mixture. Conduction of heat to the transistor via the conductors 2 is prevented by the glass bead 6 which serves as a heat sink. A crystal diode may be incorporated in the above assembly instead of a transistor. In an alternative form of the invention the semi-conductor body is merely coated with a mixture of a hardenable insulating binder and crystalline silicon carbide.

Title: Improvements in or relating to a gas-turbine blade and method of making same
IPC: F01D5/28
Filed: 1945-04-27
Abstract: 646,636. Turbine blades. LOCKHEED AIRCRAFT CORPORATION. April 27, 1945. No 6632/46. Convention date, March 6, 1942. Divided out of 646,632. [Class 110(iii)] [Also in Group II] A high temperature turbine blade comprises a core of sintered powdered metal chosen from the group' consisting of tantalum, iridium, molybdenum and tungsten and mixtures thereof encased in a bonded coating of metal chosen from the group consisting of chromium, cobalt, iron nickel and manganese and mixtures thereof. A suitable quantity of the selected metal powder such as tantulum or tungsten powder with a small proportion of suitable binding metal or metals in powdered form is hydraulically moulded to a slightly oversized approximate shape of the bucket. The moulded core is then sintered in an induction furnace at a temperature of approximately 4000‹F. in an inert atmosphere such as nitrogen, helium or argon from which oxygen is carefully excluded or in a vacuum. During this process, the core shrinks to form an undersized blank. The core is then electroplated with a protective coating of chromium sufficient to build up the blank to oversize and then heated to the forging temperature of chromium. After being allowed to soak at that temperature for the time necessary to allow diffusion and alloying of the plating and the core material at their contacting surfaces the blade is sized in dies at this temperature to the exact size of the finished bracket. The blades 12 are attached to the shell 10 by being inserted through broached openings 11 in the shell. The buckets are a light press fit in the openings and have root flanges 13 which are held firmly in place by centrifugal force. A ring 14 engages in grooves 15 in the blade roots to hold the flanges in place. Specification 646,632 is referred to.

Title: Apparatus for handling materials in strand or rope form
IPC: D06B3/34
Filed: 1954-03-11
Abstract: Apparatus for treating textile material in strand or rope form comprises a tapered roller which is driven to advance the material in a given direction over the roller and a restraining member which is situated transversely of the direction of travel of the material, the rate of travel of the material being determined by the radius of the roller at the point of contact of the material which is automatically determined by the tension in the material between the roll and the restraining member.  Figs. 2 and 3 show the application to a washer comprising a liquid containing tank 14 partitioned at 15 through which the material M in rope form is passed in zig-zag fashion via driven tapered rollers 18 associated with tapered rollers 17 and lower restraining rollers 19.  The material is prevented from running-off the rollers by upper and lower limit rods 38 and the tension in the material may be regulated by angular adjustment of roller 19 by arm 27 and handle 28.  When roller 19 has been set to any given angle the material M moves towards the end of the roller 18 having the lesser or greater radius in dependence upon the tension in the material being greater or lesser respectively than that existing at an equilibrium condition.  The upper squeeze roller may be biased downwardly against roller 18 by the provision of compression springs, (Fig. 5, not shown) or the nip between them may be inclined at an angle to the horizontal (Fig. 9, not shown).
