Title: U-bolt clamp saddle construction and method of  manufacture
Inventor: GOFORTH RONALD D
IPC: F16G11/14
Filed: 1984-10-04
Granted: 1988-04-19
Abstract: ABSTRACT           A U-bolt clamp saddle construction is disclosed particularly adapted for applications such as clamping catalytic converter pipe connec-tions requiring a rigid saddle.  The saddle clamp is of two-piece welded construction, each piece being formed of sheet steel with a square-sided channel on either side, each piece also having an intermediate web having a semicircular cutout adapted to engage the pipe diameter to be clamped.  The outer edges of each of the channels are abutted by positioning the pieces together, which pieces are then welded at weld projections located along the edges and on the web to form a high strength flangeless saddle construction for maximum clearance at installation of the clamp.  The square-sided chan-nel allows clearance for weld flash, while enabling standard sized nuts to be used.  A tab portion is formed on one of the pieces which is folded about the bottom edge and against the face of the other piece to create rigidity of the saddle during clamping adequate for good sealing pressure while affording sufficient yieldability for optimum interfitting with the pipe connection to be clamped.

Abstract: INVENTORS:  JOSEF SCHNEID and ANDREA STEIDELE INVENTION:  CALENDER        ABSTRACT OF THE DISCLOSURE     The calender comprises a predetermined number of rolls and at least one of the rolls, for example, the outer roll or the lowest roll of such predetermined number of rolls is structured as a tubular roll or controlled deflection roll comprising a stationary roll support member or beam and a roll shell which rotates about the stationary roll support member  and  is  supported thereat.   A position  sensor determines the position of the roll shell which is regulated with  respect  to predetermined reference values by  a regulating device.   A pre-selected number of different reference values for the position of the roll shell are provided and by selecting an appropriate one of these reference values there is achieved the result that different numbers of the predetermined number of rolls are operative while the remaining rolls of such predetermined number of rolls bear against related stops so that their related roll nips or gaps remain open.

Abstract: A B S T R A C T          A novel apparatus for forming depletion-free uniform thickness CVD thin-film on semiconductor wafers includes a dif-fusion furnace, a boat loader coupled to the furnace for loading and removing a batch of semiconductor wafers into and out of the furnace, and a semiconductor wafer support boat for removably retaining a plurality of vertically oriented semi-conductor wafers on the boat.  The boat includes supporting surfaces so arranged that depletion-free uniform thickness thin-film is provided on both sides of each of the vertically oriented wafers.  The semiconductor wafer support boat preferably includes two laterally spaced elongated rails each having an undulatory longitudinal section defining plural ridge portions spaced apart by plural valley portions.  The ridges on one of the rails are provided with transverse slots that cooperate with confronting transverse slots provided on the confronting ridge portions on the other one of the rails to define a plurality of wafer edge receiving channels.  The valley portions of the walls of the rails effectively shift the depletion zone away from each wafer edge receiving channel, thereby providing depletion-free uniform thickness CVD thin-film.  The system may advantageously be employed for low temperature photo chemical and photosensitized vacuum chemical vapor deposition processes.

Abstract: Abstract of the Disclosure A method for controlling a microwave oven with a micro-computer wherein a first time period corresponding to the time required to raise the temperature of a weighed food body from refrigerator temperature to room temperature and a second time period corresponding to the time required to cook the food body from an initial room temperature are calculated and stored,  The microcomputer then sequentially controls the magnetron through cycles in accordance with the first and second time periods, respectively.  Rather than being erased after completion of the first cycle, the first time period remains stored in the microcomputer and can be activated by the operator to provide a small incremental amount of heat to the food body after it has been cooked.          Also, the operator can adjust the number of heat units per weight units used in the calculation of the cooking cycle so as to provide a food body that is cooked less or more than medium doneness.

Abstract: ABSTRACT OF THE DISCLOSURE           A weighing indicator, especially for tare compensated balances, is described, by which the indicators, preferably light indicators, associated with the single weighing values are posi-tioned groupwise associated with each other.  A number of pos-sible configurations hereof are described.  In more detail thus an embodiment is described where the weight indication is pro-vided by means of a row or series of lamps, light emitting diodes or other sort of optical signalling means positioned in a Z-shaped configuration or array and whereby a preferably progres-sively sequence-coursed weight-size-indication is associated with the single signalling means.  In such case most advantageously the weight-size-indication, which corresponds to the weighing value being aimed at, is associated with the signalling means positioned nearmost to the midpoint of the stem of the Z-shape. Further embodiments hereof are described, just as also a group-wise arrangement of the signalling means within the Z-shape.  The Z-shape though is only one of many possible configurations.

Abstract: ABSTRACT OF THE DISCLOSURE            Free excess charge which is net unipolar is introduced, preferably by charge injection, into the continuous phase.  The charge transfers, through the continuous phase, to the dispersed phase and an induced electric field is thereby set up which drives the charged dispersed phase to one or more collector surfaces in contact with  the  continuous phase. According to different applications, the collector surfaces can take the form of the inside surface of a separation vessel and/or beads of low conductivity or porous material. An important application is to the dewaxing and dewatering of lube oil.

Abstract: ABSTRACT OF THE DISCLOSURE          A core structure for a dynamoelectric machine is formed of a stack of laminations and, at spaced intervals in the stack, air passages are provided by having one lamination with space blocks mounted on one side to separate adjacent laminations.  It is current practice to use space blocks of stainless steel, carbon steel and sometimes bronze, and to weld or braze the space blocks to a lamination.  This sometimes resulted in distortion due to differential expansion.  The space blocks of the invention may be of lighter material such as aluminum; they are preferably cylindrical in shape. A projection on the base of a space block extends through a hole in the lamination.  The region around the hole in the lamination is deformed into a recessed portion in the base of the space block surrounding the projection.  This leaves a depression in the lamination on the side opposite the space block.  The end of the projection is deformed, as by rivetting, and the end is received in the depression to leave a flush surface.

Abstract: BRANCH STREAM COPROCESSOR             ABSTRACT OF THE DISCLOSURE          A novel approach to reducing delays resulting  from resolution of conditional  branch instructions,  in which  such  instructions  are  pre-executed  in  a coprocessor which precedes a pipeline processor and prepares an  instruction stream  for input  to  the pipeline processor.  Because of this pre-execution, the input instruction stream has fewer  conditional branches for  the  pipeline processor  to  resolve. Also, the coprocessor may handle address generation interlock situations  which  also  cause  execution delays in the pipeline processor.
