The lugs are aligned with associated keys (14). in a modification the strip (30) is slid lengthwise around the shell Into a dovetail groove (40; Fig. 6) with overhanging edges (42) which trap the edges of the strip (30) the strip being fed in through a slot (50).  When fully in the groove the edges (42) of the groove can be spun over onto the edges of the strip.  The strip can be located in a thinwalled keyway section of the shell without the need for soldering or welding.

Abstract: CONTROL SYSTEM FOR BYPASS STEAM TURBINES          ABSTRACT OF THE DISCLOSURE                  A control system for s steam turbine operated with a steam bypass system.  In the control system, bypass valve control is according to setpoints generated as a function of a combined flow reference (CFR) signal.  The CFR signal is representative of boiler outlet flow under all turbine operating phases and is generated by multiply-ing the sum of the steam admission control valve flow demand and the high pressure bypass flow demand by boiler pressure.  An actual load demand (ALD) signal indicative of the turbine demand for steam is produced from the product of the steam admission control valve flow demand and boilder pressure, and is used for intercept valve control.  Excessive steam flow in the lower pressure bypass subsystem is prevented by providing an override for the normal control to prevent high heat impact to the condenser and latter stages of the turbine high pressure section.

Abstract: ABSTRACT OF THE DISCLOSURE      SELF RESTORING PIVOTING MEANS AND PRINT                    HAMMER USING SAME            A  pivoting means  for  pivoting back and  forth a mechanical load such as a print hammer about a given axis and within a low amplitude angle includes two elongated  leaf  springs.   The  leaf  springs  are located in planes at a given angle with respect to each other but both planes being perpendicular to the plane of pivotation of the mechanical load.  A frame  fixed relative  to the pivotable mechanical load is used for attaching the extremities of both elongated  leaf  springs.   The  mechanical  load  is attached to both leaf springs equidistant from their attached  extremities.   A power  source pivots the mechanical load from its rest position to its work or print position causing the two leaf springs to be flexed in torsion.  The torsion flexing generates a return torque for self restoring the mechanical load back to its original position.

Abstract: PAPER MACHINE PRESS WITH   A WIDE PRESSING ZONE     ABSTRACT OF THE DISCLOSURE     A dewatering press section for a paper or cardboard web includes a press roll having a wide pressing zone over which a belt is provided to run guided by guide rollers with the web being arranged to run in the pressing zone in compression between the press roll and the belt.  At least one fabric runs in the pressing zone and acts on a respective face of the web.  A pressure transmitting de-vice has a surface which overlies the belt substantially in the pressing zone.  According to the invention, ultrasonic field gener-ators are provided in association with the pressure transmitting device surface for applying an ultrasonic field substantially in the pressing zone such that the friction between the surface of the pressure transmitting device and the belt is substantially reduced.          The ultrasonic field generators can operate at a single frequency, at a plurality of discrete frequencies or may emit a continuous spectrum of frequencies and the intensity of the ultrasonic field is selected such that in addition to reducing the friction between the belt and the surface of the pressure transmitting device, the ultra-sonic field will also substantially promote the removal of water from the web within the pressing zone as well as the transfer of water removed from the web into the press fabric or fabrics.

Abstract: ABSTRACT OF THE DISCLOSURE           A gear has a housing which is formed by a housing box with an assembly orifice and with a housing cover closing the assembly orifice.  A gear shaft with a gear wheel in the housing has a bearing between the gear wheel and the housing cover.  The gear wheel interacts with a pinion which is supported by a cover shaft centered relative to the housing cover.  The cover shaft is, for example, the driven shaft of a flange motor attached to the housing cover.  Locating devices are provided for securing the exact position of the housing box and the housing cover relative to one another, which is necessary for a proper inter-action between the gear wheel and the pinion.  According to the invention, these locating devices are formed exclusively by surfaces of revolution concentric to the bearing.  They therefore require only a low production outlay.  Although they cannot fix the cover completely relative to the housing, nevertheless the existing freedom of movement of the cover relative to the housing has no effect on the quality of meshing of the gear wheels.

Abstract: APPARATUS FOR LOADING AND UNLOADING RAILWAY CARS Abstract of the Disclosure A crane is mounted on a platform having ground engag-ing legs adapted to support the platform in an elevated posi-tion straddling railroad tracks so that a railway car to be loaded or unloaded is adapted to be moved beneath the platform. The legs are adapted to be displaced between raised and lowered positions relative to the platform and are in the lowered posi-tions thereof when the platform is so ground supported.  When a railway car has been moved beneath the platform, the legs are displaced toward their raised positions whereby the plat-form is lowered onto the car to rest on the top edges of the side walls thereof.  Preferably, the legs are also adapted to be displaced laterally between extended and retracted positions relative to the platform and are retracted when the platform rests on the car to minimize lateral projection of the appara-tus relative to the car.  Clamping arrangements are provided for releasably interengaging the platform and the side walls of the car when the platform is supported thereon, and the crane is operable with the platform supported on the car to achieve the loading and/or unloading thereof.  The legs are also mounted on the platform for pivotal movement to hori-zontal positions parallel to the platform to facilitate transporting the apparatus on a flat bed railway car.  A grapple assembly is provided for the crane which enables use of the apparatus to achieve a unique method of loading rail-way ties in a gondola car.
