Patent GB-527331-A (GB)
Title: Improvements in apparatus and process for making infusions
IPC: A47J31/057
Filed: 1939-04-06
Abstract: 527,331. Infusion apparatus. NOWLAND, R. L. April 6, 1939, No. 10777. Convention date, April 9, 1938. [Class 129] The filling aperture of an electrically-heated boiling-chamber 2 is closed by a locked-down lid 8 having fixed thereto a depending tube 5 which, at its upper end and outside the chamber, supports a teapot 1 by engaging in the manner of a ball and socket joint the lower end of a rising tube 7 fixed in the teapot. A tea leaf basket 4 is supported on a shoulder 28 of the tube 7 and has a tubular core 31 which in effect extends the rising tube. A glass bell 3 is inverted over the basket and extends down into the teapot where it is formed with two holes 35 the upper one of which may be closed by a sliding spring leaf 39. In operation, when boiling point is reached, the water is forced up the tube to the top where it descends through the tea leaf basket 4 and the glass bell 3 into the teapot 1 ; the liquid rises in the teapot and covers the holes 35 in the side of the bell 3. The heating unit is cut out as soon as the water in the boiling chamber 2 falls below the bottom of the tube 5 since a bimetallic strip which is housed in a pocket 50 then uncovered by the water, experiences a substantial rise in temperature and a contact in the heater circuit is opened. On cooling, a partial vacuum arises whereby the liquid rises inside the bell 3 and covers the tea leaf basket 4. The liquid of course falls at the outside of the bell and when the topmost open hole 35 is uncovered some air flows into the bell to agitate the liquid, some liquid flowing out so that the hole is again covered. This action recurs as the cooling proceeds. When the infusion process is considered to have been sufficient a valve 25 on the boiling chamber is opened to destroy the partial vacuum whereby the liquid inside the bell 3 drops away from the tea leaf basket. The teapot is then lifted off the boiling chamber and used in the ordinary way. The usual small vent 26 in the rising tube 5 is located in recessed portion 27 of the lid 8 so as to be above the level of the filling aperture of the boiling chamber which has corrugations 44 to serve as gauge marks. The bell is held in position by spring fingers 36.

Title: Improvements in or relating to the formation of fibrous protein from solutions of collagen
IPC: D01F4/00
Filed: 1952-04-30
Abstract: Fibrous proteins whose fibres have axial periods several times that of normally occurring collagen is prepared by mixing mucoprotein with an acidic aqueous solution of collagen and causing precipitation of the fibres from the solution to take place by dialysis of the solution against water.  The product may be a mixture of long period fibres and normal period fibres (640  ) or may be almost wholly long period fibres depending on the amount of mucoprotein used.  The mucoprotein may be employed in pure form or in the crude state as in deproteinized blood serum or plasma.  The collagen solution may be obtained by extracting animal connective tissue with an aqueous acidic medium.  Thus, the tissue may be treated, if desired, with an alkaline buffer, e.g. 0.05 M disodium phosphate, and then extracted with an acid buffer of pH 3.0 to 4.0 and ionic strength of 0.1 to 0.2, e.g. a citrate buffer solution.  Suitable tissues are calf skin, steer hide, rat-skin and rat-tail tendon.  Examples describe the preparation of mucoprotein from beef cattle plasma or serum and its use in the formation of the desired long-period fibres from a collagen solution obtained by repeatedly treating embryonic calf skin with an alkaline disodium phosphate buffer and then extracting the treated skin with 0.05 M citrate buffer solution of pH 4.0 for 15 to 48 hours at 0-5 DEG  C., the mucoprotein being used in the proportion of 1 part per 100 parts of collagen.

Abstract: 980,716. Fluid-pressure servomotor systems. ROBERTSHAW CONTROLS CO. March 19, 1963 [March 22,1962], No. 10845/63. Heading G3P.  A pressure actuated control device comprises low limit, high limit and operating chambers 44, 46 and 48, respectively, an actuating member 172 responsive to expansion and contraction of the operating chamber, means 38 to connect the low limit chamber with the high limit chamber upon expansion of the low limit chamber at a preselected pressure value, and means 40 for connecting the operating chamber with the low and high limit chambers to expand the operating chamber upon expansion of the high limit chamber at a higher pressure value, the last means being operable for disconnecting only the high limit chamber upon subsequent contraction thereof at an intermediate pressure value. Signal pressure applied to port 98 flows through channels 96a, 96 and 96b to act on the underside of diaphragm 38 which is lifted at a pressure determined by the setting of an adjustable spring 132 to permit an exhaust valve 80 to close, isolating the low limit chamber from atmosphere, and to open a valve 56 connecting the low limit chamber and signal pressure conduit to the high limit chamber 46 through radial channels in its lower annular face and a channel 92. A channel 90 leading to a port 112 in the operating chamber 48 is also placed in communication with the chamber 44. When the signal pressure reaches a value determined by the setting of a second adjustable spring 146, it lifts a diaphragm and flows through channels 94a, 94, and 94b to lift the diaphragm 42 and the actuating member 172. The port 112, opened by the movement of the diaphragm, connects the operating and low limit chambers to each other so that the actuating member remains in its operative position until the signal pressure has fallen to the lower value at which the diaphragm 38 again opens the valve 80. The actuating member may be the plunger of a switch 168 or it may be an adjustable link 242 for operating a valve 200, Fig. 11, which in the position shown permits fluid to flow from a supply port 258 through an annular passage 228 to a port 226. When the link 242 is lifted by expansion of the operating chamber 48 a valve 230 closes the passage 228 and flow is diverted through a bore 256 to a port 260. A loading spring 250 and a balancing chamber 216, connected by a passage 222 with the supply port 258, are provided. Dials 136, 148 show the setting of the springs 132,146.

Abstract: 794,297. Speed indicators. GAYLORD PRODUCTS, Inc. April 10, 1956 [May 2, 1955], No. 10877/56. Class 106 (3). [Also in Groups XXXVII] A switch, arranged to give a signal or perform a control at a predetermined speed, comprises a rotatable body, a pair of driving plates secured to the body in spaced axial relation, a driven plate loosely embracing the body between the driving plates and in face-to-face relation with the driving plates, means adjacent the periphery of the driven plate to hold it in an eccentric position relative to the body when stationary, and means for coupling the opposed faces of the plates for rotating the driven plate and for radially moving said plate toward a concentric position when the body rotates at the predetermined speed. The rotatable body 1 may form part of or be attached to a speedometer cable and the driving plates 12, 14 are keyed thereto at 13, 15. The driven plate 16 has a large central aperture 17 and is coupled to the plates 12, 14 by a plastic material 18 having high viscosity and high shear strength, e.g. a silicone oil, grease or paste. When stationary, the plate 16 is urged into the eccentric position shown by a spring 25 of a normally-closed snap-action switch 22 acting through a lever 30 pivoted on a bracket 24. When the body 1 is rotated, the plate 16 is subjected to two opposing forces: (1) that due to the viscosity and shear strength of the material 18; and (2) that due to the spring 25, until at the predetermined speed the plate 16 becomes more concentric and the switch 22 is opened. Stops 38, 39 assist the plate to become concentric and maintain it so above the predetermined speed. In a modification, Fig. 6, force (2) above is provided by a spring 56 carrying a contact 58 engaging the plate 52 which normally also engages a fixed contact 60. At the predetermined speed, the contact 60 is disengaged. The plate 52 may be magnetic and coact with magnets 64 which helps to maintain its eccentricity until the desired speed is reached. In a further modification, Fig. 7, the eccentricity is provided solely by two magnetic contacts 66 which are normally bridged by the plate 65.

Title: Improvements in and relating to trunk communication electric cables comprising one or more screened core groups
IPC: H01B11/06
Filed: 1935-04-09
Abstract: 449,582. Cables. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. April 9, 1935, No. 10989. Convention date, July 17, 1934. [Class 36] In a trunk communication cable comprising one or more screened core groups, such as pairs or quads, and more particularly a high frequency cable, the screens are constituted by a plurality of good conducting metal strips or wires which are stranded around each core group in the same direction as, and with the same pitch as, the cores of the group. Fig. 2 shows a cable having a single core group consisting of conductors 10, 11 each having an air space insulation formed by a helically wound insulating cord 13 and an insulating sheath 14. The conductors 10, 11 are formed as thin metal tubes each supported by an insulating cord 12. Insulating fillers 15 are laid up with the two cores and the core group thus formed is surrounded by an insulating sheath 16 which supports a closed screen 17 consisting of thin overlapping copper strips stranded around the sheath 16 in the same direction as, and with the same pitch as, the conductors 10, 11. The screen is protected by an insulating sheath 18 and a lead jacket 19. The fillers 15 and insulating sheath 16 may be omitted and the screen supported by a member, such as a wire, which is wound under the screen as an open helix around the core group. Similar constructions of cables containing four core groups are described. In modified constructions the screens consist of two superposed layers of strips, the strips of the outer layer covering gaps between the edges of adjacent strips of the inner layer ; or the strips may be arranged in superposed pairs of which the edges of each pair at one side are spread apart to provide a recess into which the other side edges of the adjacent pair of strips are inserted. In another arrangement, Fig. 8, the screen consists of alternating single strips 62 and pairs of superposed strips 63, 64. According to the Specification as open to inspection under Sect 91. the screen may comprise thin wide strips 70, Fig. 11 (Cancelled), between which are disposed thick wires 71. A strip 72 may be wound over the screen to prevent displacement of the wires 71. This subject-matter does not appear in the Specification as accepted.
