Abstract: ABSTRACT OF THE DISCLOSURE            A thermostatic control having a housing in one wall of which is mounted a temperature responsive heat motor means which includes a movable member and in an opposed wall there is an abutment with a flat spring member mounted between the movable member and the abutment and having a length greater than the distance between the movable member and the abutment whereby the spring member is initially bowed.  Movement of the movable member changes the bow of the string to actuate a control device.  The coefficient of expansion of the spring and the housing are substantially the same whereby the control is temperature compensated.

Abstract: ABSTRACT     A preferred glassware forming machine has a neck ring carriage for transferring parisons from a blank station A, to a further station B.  The carriage is guided for horizontal reciprocatory motion on two spaced, parallel guide rails and carries two relatively movable neck ring parts which engage the necks of the parisons during the transfer of the parisons from station A to station B.  Relative movement of the neck ring parts is effected by piston and cylinder devices which are carried by the carriage and which are operated by compressed or suction fluid supplied to the carriage through one or both guide rails, the application of the compressed or suction fluid to one or both guide rails being in timed relationship with movement of the carriage.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for maneuvering a ship having Z-type propel-ler structure.  A maneuvering handle provides a proportional relationship of ship speed and ship direction with its inclina-tion angle and rotation direction respectively.  A generally cylindrical rotation frame is rotatably supported by a stationary frame, a rotation shaft is disposed along the diametrical direction of the rotation frame, and a maneuvering handle is positioned at the approximately central portion of the rotation shaft.  The lower end of the maneuvering handle is connected to the rotation shaft.  The rotation shaft is rotated about its axis by the pivotal movement of the handle.  Further-more, a hollow shaft is rotatably disposed coaxial with the rotation frame.  The hollow shaft is provided with first and second central gears.  A central shaft rotatably disposed in the hollow shaft has one end provided with an ahead-astern changing gear and the other end provided with an arm member. The central shaft further provides a loose gear and a bevel gear both being freely rotatable thereabout, and the arm member rotatably supports an intermediate shaft having one end provided with a first intermediate gear and the other end provided with a second intermediate gear.

Abstract: ABSTRACT OF THE DISCLOSURE     The type of conductor, its property, and if a metal, its type and cross-sectional area can be obtained from measurements made at different frequencies for the amount of unbalance created in a previously balanced stable coil detection system.          The true resistive component is accurately measured and thus reflects only the voltages loss attributable to eddy currents caused by intro-duction of the test sample to the coil system.          This voltage divided by corresponding applied frequency gives a curve which peaks at a frequency dependent upon type of conductor.  For a metal this peak frequency is proportional to the samples resistivity divided by its cross-sectional area.

Abstract: Abstract of the Disclosure An efficient, compact boiler system providing both heating water for heating an enclosed space, such as a home, and domestic hot water for washing and similar purposes, has a limited fluid capacity primary heating coil within a combustion chamber.  The coil supplies heated water to a larger capacity storage boiler located directly below the primary boiler and connected to it by header pipes which themselves form a manifold into which the primary coil is connected.  The storage boiler distributes the heated water through the heating system.  An elongated secondary heating coil within the boiler heats the domestic hot water supply by heat trans-fer from the boiler water.  The return header pipe discharges heated water directly into the interior loop of the secondary coil to quickly heat the domestic hot water when the burner is "on".

Abstract: ABSTRACT            "IMPROVEMENTS IN OR RELATING TO THE REMOTE CONTROL  OF ELECTRICAL DEVICES"             A remote control system for use e.g. in controlling the locomotives and ancillary devices of a model train layout comprises a transmitter and a number of receivers incorporated in the devices to be controlled.  A composite waveform is applied across the tracks, comprising a rectangular power supply waveform with intervals between positive and negative path cycles and control signals which occur in the latter parts of these intervals, the delay between the end of each half cycle and the control signals allowing time for reactive currents resulting from inductive loads to decay.   The composite waveform is synthesised by two switching amplifiers driven by a microprocessor and having associated with it slider controls and a keyboard for controlling the receivers.  The receivers are programmed to identify control signals addressed to them and to control an associated locomotive or an ancillary device appropriately.  The address to which each receiver responds can be programmed by selective breaking of a number of tabs on a circuit board on which the receiver IC is mounted.

Abstract: HIGH VERTICAL CONFORMANCE STEAM DRIVE OIL RECOVERY METHOD           (D#74,837-F) ABSTRACT OF THE DISCLOSURE The vertical  or both vertical  and horizontal conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with one or more infill wells in fluid communication with the bottom half or less of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well.  After the water cut of the fluids being produced from the infill well reaches 95 percent, the infill well is converted from a producer to an injector and steam is injected into the infill well and fluids are recovered from the production well.  When one infill well is employed in a more or less aligned arrangement between injection and production wells,  the vertical conformance is improved.  When one or more infill wells are positioned in an offset or nonaligned arrangement relative to each injector and producer, conformance in both the horizontal and vertical planes is improved.  By this multi-step process involving the infill wells, the amount of oil recovered from the portion of the formation in the recovery zone defined by the injection and production well is increased significantly.                             -I-

Abstract: APPLICANT: MORGARDSHAMMAR AKTIEBOLAG            TITLE:     METHOD FOR REGULATING THE THROW ANGLE OF A            VIBRATING SIEVE OR FEEDER         ABSTRACT OF THE DISCLOSURE     In a sieve or feeder there are two out-of-balance weights rotating in opposite directions, each driven by its own motor, preferably of asynchronic type. Together they achieve a shaking movement, in which the out-of-balance weights, by mechanical coupling, will normally force the motors to keep such a speed and phase that they will be synchronized. An elliptical stroke can be obtained thereby if the out-of-balance weights are different and if the center of gravity of the shaken mass is suitably placed. The direction of stroke can be altered by changing the ratio between the powers  supplied to the two motors.

Abstract: ABSTRACT OF THE DISCLOSURE To reduce the ohmic losses in a sheet-wound trans-former or reactor winding, edge regions of at least some of the turns of the conductor sheet forming the winding are located at a different distance from the geometric axis of the winding compared with the distance from said axis of a central conductor portion in a respective one of said turns.  Preferably the conductor sheet in each turn substantially follows the flux lines for the resultant magnetic leakage flux which corresponds to a constant current density in the sheet.  For example, the winding may be wound from a metallic foil whose edge regions are folded back on themselves, or end regions of the winding may be provided with inter-turn packings (e.g. of tape) to achieve the desired flared shape of the turns at the ends of the winding.
