Abstract: 1442144 Catheter ASTRA-SJUCO AB 23 Nov 1973 [24 Nov 1972] 54593/73 Heading A5R A catheter intended for the submucous administration of a local anaesthetic into the cervix during childbirth comprises a tube 1 provided with a collar 2 adjacent to one end. The collar, which encircles the whole circumference of the tube, is flared out into the form of a funnel the largest diameter of which 3 is nearest to the opposite end of the tube. The catheter is made of a flexible plastics material such as polyethylene or polytetrafluoroethylene, and the object of the flared collar is to retain the catheter in place after insertion. After the delivery is finished the catheter is removed by drawing it backwards, when the collar turns inside out, and thus does not cause any enlargement of the puncture. The flared part of the collar may form an angle of 30‹ to 45‹ with the axis of the tube, and the tube may have a diameter of 1.5mm., with the largest diameter of the collar from 3.5 to 4.5 mm. The catheter is placed in the mucous membrane of the cervix to a depth of 3-4mm. by the use of an introduction tube and a pointed mandrel inserted into the catheter. In another embodiment, Figure 2 (not shown), the collar has from three to six slits in its flared part parallel to the tube axis, to make it more readily conformable with the outer surface of the tube.

They may be prepared by reacting a dianhydride with a diamine in a solvent for at least one of the reactants at below 100‹C to give the corresponding polyamide- and which is then cyclized while still in solution either by heating at 100‹ to 240‹ C., or with a chemical dehydrating agent at about 120‹ C. Various solvents are specified. The solutions are useful for adhesives, laminating resins, fibres or decorative or insulating coatings or the polyimide may be precipitated and subsequently redissolved or used as a moulding powder, optionally with fillers, dyes, pigments or stabilizers. The polyimides cross-link to an insoluble state without eliminating volatiles on heating above 225‹ C. under atmospheric conditions. The dianhydride and diamine may be reacted in molar ratios from 2 : 1 to 1 : 2, excess of either reactant giving lower molecular weight polymers which may be reacted with chain extending agents to give polymers useful as adhesives or moulding a laminating resin. They may also be chain terminated with phthalic anhydride or aniline or wire reactive compounds such as maleic or olefinic endomethylenehydrophthalic anhydrides in which case they may be subsequently heated to induce cross-linking and chain extension. The preparation of the diamine reactant is described and claimed in Specification 1,420,310. Reference has been directed by the Comptroller to Specifications 1,241,445 and 1,255,935.

Three expansion engine stages M1, M2, M3 are provided, air being supplied to one in accordance with the position of the valve 5 controlled in conjunction with throttle valve 2 by the pedal 4. When the device to be driven by the expansion engine (e.g. a refrigerator compressor 22) is required to operate, button 10 is pressed in and button 12 withdrawn Fig. 2, so that throttle valve 2 remains closed and induction air flows through the expansion engine 3.

In another embodiment, Fig. 7 (not shown), a single stage expansion engine is provided; but the expansion ratio can be varied by changing the eccentricity of the rotor (86) relative to casing (87) by pivoting the casing about pivot (85). A button (77) operates a gate valve to connect or disconnect the expansion engine. The expansion engine may alternatively be a turbine whose performance can be varied by changing blade angles. The use of magnetic coupling 7 enables the whole of the refrigerator gas cycle to be hermetically sealed so that no leakage of refrigerant can occur.

Abstract: 1469850 Electroslag refining; moving-mould machines; continuous casting INST ELEKTROSVARKI IM E O PATONA AKAD NAUK UKRAIN SSR 30 Dec 1974 56040/74 Heading B3F An electroslag refining machine for producing curved ingots from curved consumable electrodes comprises a water cooled mould 1, on a frame 2, with curved walls 3, 4 to shape the refined ingot, with the radius of curvature being the same as the curved electrode 15 which is being milled. A drum 6, rotatably mounted on a shaft 5 at the common axis and driven by a drive 9 through a coupling 8, has attached through a bracket 10 an ingot base-plate 11 with dummy bar 12. An electrically insulated electrode holder 14 is mounted on the drum, and electrode 15 is attached by one end to holder 14. The electrode is supported by spring loaded rests 16 on drum 6, the rests being adapted to support the refined ingot 19 after casting. The other face of ingot 19 is supported from below by rollers 21. An electrical supply 20 is connected across holder 14 and base-plate 11. The operation is by rotating drum 6 to place base-plate 11 carrying the dummy bar 12 into engagement with the underside of mould 1, while electrode 15 is placed a short distance from base-plate 11. Slag is ladled into the mould and an electrical voltage applied between electrode 15 and base-plate 11. Due to the heat liberated in the slag, electrode 15 melts and forms a pool around bar 12 to form refined ingot 19. Drum 6 is then rotated at a controlled rate to withdraw the refined ingot 19, which rests on rests 16 and is supported by rollers 21. When the required length of ingot is obtained, the drum is halted and the current switched off. The stubs of electrodes 15 are removed, drum 6 further rotated to clear ingot 19 from mould 1, and the mould moved horizontally away from the drum. Drum 6 is then rotated to place ingot 19 in the " above drum " position, dummy bar 12 removed from base 11 and the ingot removed. Another embodiment (Figs. 3, 4, not shown) utilizes the surface of drum 6 as one of the mould walls, with passages (22) for supplying coolant. A flat (23) is made on drum 6 to permit removal of refined ingots 19, with a movable stop (24) mounted on frame 2 to prevent " twist " of the ingot during removal. A further embodiment replaces rests 16 by electrical insulating gaskets (28) which may be slag which are melted into the bath. A further embodiment (Figs. 5 and 6, not shown) permits the manufacture of ingots with toothed outer surfaces, by replacing mould wall 3 with a wall which extends around the periphery of drum 6 and rotates with it and contains recesses in the form of prefabricated elements (29) in the form of teeth, which fuse with the ingot during casting.

The apparatus, Fig. 1, may comprise struts 1, 2 carrying a bridge 5 having a plasticizing cylinder 3 with an open nozzle 12 and a bridge 7 carrying screw conveyer 6. Bridge 7 is reciprocated by hydraulic cylinder 8 and screw 6 is rotated by fluid motor. During plasticization, screw 6 is forced back until switch 28 is actuated by rod 27 mounted on bridge 7, stopping motor 10 and retracting piston 48 of cylinder 8, thereby relieving the pressure of the plasticized material. Bridge 5 is then moved with bridge 7 when abutment 25 on rod 23 which is mounted on bridge 7 engages extension 21 on bridge 5, which also ends the relative relaxation movement so that cylinder 3 is disengaged from the mould (not shown) without any material extruding from nozzle 12. After removal of the previous moulding, the injection stage is initiated by microswitch 34 and second stage injection when the mould is almost or completely full by microswitch 33. Cylinder 3 is prevented from moving with screw 6 during the plasticizing movement by friction rings 19 on struts 1, 2.

Differential 4-phase modulated signals, in which each phase represents a pair of bits, are demodulated in a circuit in which a reference carrier frequency signal is derived from the received signals for demodulating the signals, the demodulated signals passing to a logic circuit which reconstructs the binary data represented by the received signals. The received signals pass to two demodulators fed by the reference carrier respectively direct and via a 90 degrees phase shifter. The reference carrier is obtained by squaring the received signal twice and dividing the resulting signal by four, or by rectifying the received signal, filter. ing the fourth harmonic of the received signal and dividing by four, and consequently the carrier may have any of four phases relative to the received signals. The demodulator outputs consist of binary signals whose state depends on the relative phases of the received signals and reference carrier and pass via limiters both direct and via 1-bit delays to the logic circuit. Each input to the logic circuit consists of a pair of leads which are marked alternatively. The logic circuit develops a sequence of two-bit parallel signals, corresponding to the original bit pairs, the parallel signals then being serialized.
