Abstract: 258,897. Erste Bohmische Kunstseidefabrik Akt.-Ges. Sept. 25, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Alkali cellulose.-Alkali cellulose for use in the manufacture of artificial silk, particularly according to the viscose process, is prepared in the form of a well-opened downy mass by subjecting the cellulose moistened with lye to the action of high speed reduction machines having a breaking or impact action, such as impact cross mills or spiked roller mills.

Title: Improvements in bell ringing apparatus
IPC: G10K1/34
Filed: 1947-08-28
Abstract: 633,025. Control of motors. GILLETT & JOHNSTON, Ltd., and HOUSMAN, R. F. A. Aug. 28, 1947, No. 23867. [Class 38 (iii)] [Also in Group XXXVIII] A church or like bell is kept swinging at its natural rate by an electric motor controlled by the device illustrated. The motion of the bellshaft 10, Fig. 2, rocks a crank-arm 11 and a shaft 9 which extends into the interior of a housing 3 whose front is covered by a removable transparent disc 4. If the bell swings beyond a predetermined extreme position, a cam 15 mounted on the shaft 9 engages and rocks a lever 18 against the action of gravity to release a mercury switch 16 which swings against a stop 20, Fig. 1, opening the circuit of the motor driving the bell. The oscillation of the bell is started under manual control, and when it has attained a sufficient amplitude an automatic maintaining switch 23, of the mercury type, is put into circuit. A pin 22 on an arm 21 clamped to the shaft 9 then passes under a short detent 29 and engages a longer detent 28 during the counter-clockwise (Fig. 1) swing of the bell, both detents 28, 29 being clamped to an arm 26 freely pivoted on a lever 25. On the return (clockwise) movement the pin 22 engages the lower end of the short detent 29 and lifts the arm 26, thereby tilting the lever 25 and operating the maintaining switch 23 to close the motor circuit for a short time. If the amplitude of oscillation reaches the maximum required, the pin 22 passes under both detents and merely rotates the arm 26 without lifting it on the return movement. The position of the bell is shown by an indicator driven from a potentiometer 31 whose operating shaft 36 is rotated by means of a driving disc 35 having a notch which engages a projecting tooth on a spring strip 34 secured to the shaft 9. Movement of the potentiometer beyond its permissible limit is prevented by the engagement of a stop 38 with the ends of an arcuate plate 37 mounted on the driving disc 35, the tooth on the spring strip 34 slipping out of the notch in the disc 35 to re-enter it on the return swing.

Title: Method of strengthening alloy steel
Inventor: HILL MORSE
IPC: C21D8/00
Filed: 1964-10-28
Abstract: A method of strengthening an alloy steel, which quenches to martensite from the austenitic state, comprises austenitizing it, reducing the sectional dimensions thereof by at least 10% by plastic deformation conducted above the nose of the TTT curve thereof to impart a worked austenite structure and immediately rapidly cooling it so that no appreciable amount of higher temperature transformation products is formed.  The cooling may be sufficiently low to give a martensitic structure or it may be such as to give a bainitic structure which will require an isothermal treatment.  The body may be tempered at 400-1000 DEG F. The application of this method to the steel of Specification 1,089,934 is also disclosed.

Class 64(iii) In a heat exchanger comprising a bundle of finned tubes 14 extending between tube plates 2, 3 with headers secured thereto for the passage of a heat exchange medium through the tubes and wherein a second heat exchange medium under high pressure flows over the tubes, plain tubes 15 are provided at least some of which replace finned tubes within the tube bundle, the plain tubes 15 being made oi material having a relatively high tensile strength as compared with the finned tubes which consist of material of high thermal conductivity. Additional finned tubes 14 may be provided outside the tube bundle to compensate for the reduction in efficiency caused by replacing some of the finned tubes by plain tubes within the bundle. Additional plain tubes 15 also may be provided around the tube bundle and this it is stated results in a more balanced stress distribution in the tube plates. One end of each finned tube 15 is enlarged in diameter to permit these tubes to be withdrawn for cleaning purposes.

Title: Thermostatic electric switch
IPC: H01H37/48
Filed: 1956-08-07
Abstract: 799,971. Thermal switches. TRIGGS, W. W. (Kidde & Co., Inc., W.). Aug. 7, 1956, No. 24143/56. Class 38 (5). In a thermostatic switch that is sensitive to small departures from a normal high operating temperature (for example, 1000‹ F.) of the apparatus controlled, means are provided for preheating the thermostat to or near its operating temperature so that it may be ready for instant operation, if necessary. As shown, the expansible tube 14 of a differentiallyexpanding rod-and-tick thermostat has a heating coil 100, the ends 102, 104 of which are led out through hollow binding posts. The rod 20 is of ceramic or other very low expansion material and co-operates with an L-shaped member 50 pivoted on a pin 48 between lugs 42, 44 of the casing and biased clockwise (Fig. 1) by a wire spring 52. A movable contact 64 is pivoted on a pin 62 in a slot in member 50 and biased anticlockwise by a wire spring 68. At normal operating temperature, contact 64 lies out of contact with fixed contacts 82, 84, but at lower temperatures the rod 28 moves upwards and rotates member 50 so that contact 64 engages contact 82 and causes the heater 100 to be energized. At higher temperatures, the rod descends and spring 52 rotates member 50 so that contact 64 engages contact 84 to sound an alarm or disconnect the plant. As applied to a jet engine where the operating temperature is reached soon after starting up, the coil 100 is switched in in advance in case of malefunctioning of the engine.

The emitter of a controlled rectifier is made by alloying a perforated impurity containing foil to a body of silicon and subsequently applying a different contact material over the alloyed foil so that it makes ohmic contact with the adjacent region of the silicon body through the perforations in the foil. Typically the emitter foil is of gold-antimony and has from 30-100 uniformly spaced holes of about 0À01 inch diameter occupying from 7À5-17% of the area of the foil. The holes may be punched or drilled in the foil but are preferably formed by rolling the foil from a compaction of the alloy and particles of a soluble filler e.g. sodium chloride and then dissolving away the particles. After alloying, the emitter is vapour coated with gold or aluminium, with the rest of the silicon body masked. Following sintering at 450‹ C. in hydrogen a molybdenum contact is attached to the coating. Reference has been directed by the Comptroller to Specification 969,592.
