Abstract: CLUTCH-TO-CLUTCH POWER-ON DOWNSHIFTING IN A MOTOR VEHICLE AUTOMATIC TRANSMISSION            Abstract of the Disclosure A clutch-to-clutch power-on downshift in a motor vehicle automatic transmission is effected by reducing the torque capacity of the off-going clutching device to permit the transmission input speed to increase toward a target speed which it will finally attain subsequent to the shift; increasing the torque capacity of the off-going clutching device and preparing the on-coming clutching device when the input speed approaches its target speed so that the input speed is held near the target speed by the time the on-coming clutching device is prepared to transmit torque; and concurrently applying and releasing the on-coming and off-going clutching device to complete the shift.  Since the input speed is substantially at its target value when the exchange of clutching devices occurs, a high quality shift with minimal driveline torque disruption results.

Title: Roof drain assembly, and method of forming a roof  drain assembly

Abstract: ABSTRACT OF THE DISCLOSURE          In a roof drain assembly comprising an existing roof structure having an opening therethrough with a drainage duct extending downwardly through the opening, and a re-roofing structure which includes a layer of insulation and which is disposed over the existing roof structure with an opening through the re-roofing structure in alignment with the opening through the existing roof structure, a drain extension pipe extends through the opening in the re-roofing structure and into the upper end portion of the drainage duct.  The portion of the drain extension pipe within the drainage duct is of a non-resiliently deformable material such as lead, and this non-resiliently deformable portion of the drain extension pipe is outwardly mechanically deformed against the drainage duct to provide a substantially water-tight seal therebetween.  This back-up of rain-water between the drain extension pipe and the drainage duct and which could cause deterioration of the insula-tion of the re-roofing structure is substantially prevented in a manner which is less expensive and more effective than previously proposed and used arrangements for achieving this objective.  The outward mechanical deformation of the non-resiliently deformable portion of the drain extension pipe is achieved by means of a tool including an expansion assembly comprising an upper plate, a lower plate spaced below the upper plate, and a resili-ently deformable annulus disposed between the upper and lower plates.  In use an outer tube to which the upper plate is secured is prevented from turning, and an inner shaft which is screw-threadedly disposed through the upper plate and on the lower end of which the lower plate is mounted is turned in the appropriate direction to cause the lower plate to move towards the upper plate with resultant axial compression and outward expansion of the resiliently deformable annulus against the non-resiliently deformable portion of the drain extension pipe.

Abstract: HIGH SPEED LOAD TRANSFER SYSTEM          ABSTRACT OF THE DISCLOSURE:     A  high  speed load transfer system for  use  with critical loads,  e.g.  computers,  includes a high speed transfer  logic  circuit  which has  rapid  sensing  and rapid contactor energizing means;  so that in the  event of  power  failure,  power to the critical load  can  be switched instantaneously to an alternative power supply.          A  solid  state  sensor,  responsive to a  step  change, detects  instantaneous  power failure  and  operates  an output  to a contactor.  A voltage doubler circuit using an  AC  input  capacitor and a DC  output  capacitor  is provided  at  the  contactor,   with  the  DC  capacitor connected across the contactor;  so that when a transfer signal is received at the contactor, the DC capacitor is discharged  across  the contactor,  so as to  provide  a surge  of power through the switch means when the switch means closes and to minimize contactor response time  --as  well  as to ensure connection to the critical  load.          The power supply can be a commercial AC line,  or a  hot standby  inverter.  In  one embodiment,  a  differential voltage  sensor  is provided in parallel with  the  step sensor to sense voltage failure such as  brown-outs,  or failures within a set time interval e.g., 2-4 msec after the  event.  In another embodiment,  an inverter voltage sensing circuit is provided for switching power from the inverter to a bypass AC line in the event of overload.

Abstract: A blank of the type that has a plane, essentially rectangular base part 27 and side wall parts 28, 29 is raised in an apparatus to form a packaging by means of bending elements 12; 15; 18, 20, 22; 19, 21, 23 for bending side wall parts 28, 29 of the blank over along fold lines in relation to the base part 27 of the blank. The bending elements 12 for bending one of the side wall parts 29 of the blank over are connected to a support surface 10 in the apparatus by way of a hinge connection 8 and are designed to rotate between a first position and a second position, in which first position the bending elements 12 extend upwards from the support surface 10 and in which second position the bending elements 12 are swung down below the plane defined by the support surface 10. The hinge connection between the bending elements 12 and the support surface 10 is formed in such a way that the axis of rotation defined by the hinge connection in the first position passes through the bending elements 12 below their centre of gravity, which allows the bending elements, during a movement of the support surface 10 in relation to a second support surface 13, to rotate from the first position to the second position, so that it is possible to simply remove the raised packaging, filled with contents and possibly sealed, from the apparatus without lifting this packaging out of the apparatus, which affords a considerably work effort saving and at the same time makes the work much easier. <IMAGE>

Abstract: A method is disclosed forming a membrane over a standard diaphragm cell foraminous electrode and may comprise the steps of suspending a matting material in a liquid medium, inserting a foraminous electrode into the suspension, vacuum forming a layer of the suspended matting material over the surface of the foraminous electrode so as to substantially reduce the porosity of the foraminous electrode material, applying to the surface of the foraminous electrode with the matting material thereon; a layer of thermoplastic material which includes particles of perfluorosulfonic acid resin in the sulfonyl fluoride form, baking the foraminous electrode with the layers in place until the thermoplastic material is fused into a thin and uniform film on the surface of the matting material which is substantially permeable to hydraulic flow and hydrolyzing the perfluorosulfonic acid resin to change the sulfonyl fluoride form to the cation exchange sulfonic acid form. The forming of the membrane over a standard diaphragm cell electrode assembly eliminates substantial cathode costs involved currently for converting the diaphragm electrolytic cell to a membrane electrolytic cell.
