Abstract: 584,308. Tubular heat-exchangers. SVENSKA CELLULOSA AKTIEBOLAGET. Jan. 11, 1944, No. 527. Convention date, Dec. 11, 1942. [Class 64 (iii)] In a heat-exchange apparatus in which one medium passes through a helically wound pipe structure whilst the other flows exteriorly of the structure and within an enclosing casing 1, the pipe structure consists of two or more pipes 6, 7, 8 of flattened crosssection which are wound edgewise to the form of helices, the turns of the helices being of such diameter as to define a cylindrical, a conical, or an oval or other non-circular cylindroid structure, and the helices being interengaged one within another to form a structure resembling a multi-start screw thread. The three helical tubes 6, 7, 8 in the form shown are found around a core 9, to which one of them is fixed, and are connected at their ends to headers 13, 19. The casing 1 may be spaced a short distance from the coils to allow impurities separated by centrifugal action to fall to the bottom. The casing may have helical corrugations, and be provided with cleaning shutters or blow-out pipes and windows for inspection. The convolutions of the coils may be of varying thickness axially, or varying pitch. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 581,374, a slight modification thereof in which the units forming a helix are held together by external bolts, and other forms of heat-exchange apparatus with one or more helical tubes. In one form, one or more helical tubes of flattened cross-section with ends of circular cross-section are twisted about its or their own longitudinal axis to form the helical passage or passages. In another form there is only a single helical tube without a core. The changes of thickness or pitch of the coils may correspond to the change in density of a fluid due to heating or cooling. The outside casing may be omitted, e.g., for heating or cooling air in a building. This subject-matter does not appear in the Specification as accepted.

Abstract: PCT No. PCT/GB90/00025 Sec. 371 Date Aug. 31, 1990 Sec. 102(e) Date Aug. 31, 1990 PCT Filed Jan. 9, 1990 PCT Pub. No. WO90/08024 PCT Pub. Date Jul. 26, 1990.In a method and apparatus for formation of an extruded product from material containing fibrous, molecules or other constituents succeptable to alignment, while the extrudate is still molten and moving through the die (5), in the direction of the extrusion axis (11), it is subjected to pulsating displacements in a direction transverse relative to that axis. These displacements give rise to a shearing action within the material, resulting in a degree of transverse orientation of the constituents. This orientation may be "locked in" to the extruded product when the melt solidifies (40), so improving the transverse strength of that product, and/or may correct an unwanted orientation (from 112, FIG. 16) that existed in the melt upstream of the point where the pulsating displacements were applied. The displacements may be applied by the synchronized operation of pistons (20-27), operating in chambers (17) which open into the die cavity (18) at separated locations all lying in the same transverse plane. The extrusion of products of rectangular, tubular and other sections is described, as are various methods (8a, 8b, 9, 10, 37) of applying forced cooling to the die to accelerate the solidification of the molten product.

Title: Improvements in or relating to electronic timepieces with stepping motor driven analog time displays
IPC: H02P8/02
Filed: 1984-03-01
Abstract: An electronic timepiece including a dividing circuit for developing different output pulse signals having different respective pulse repetition rates, a stepping motor and a drive circuit responsive to control signals for driving the stepping motor at a normal rate and for applying a correction pulse to the stepping motor according to the control signals. A pulse combining circuit combines the different output pulse signals from the dividing circuit for generating control signals and for applying the control signals to the drive circuit. The pulse combining circuit normally generates a control signal effective to drive the stepping motor at a normal rate, and the pulse combining circuit is responsive to a correction signal to control the drive circuit to apply a corrective pulse to the stepping motor. A detection circuit detects rotation and non-rotation of the stepping motor rotor and generates a detection voltage signal indicative of the state of rotation of the rotor. A voltage comparing circuit compares the detection voltage signal with a standard voltage value and applies a correction signal to the pulse combining circuit when non-rotation of the stepping rotor is detected after a drive pulse is applied to the stepping motor.
