Title: Transcendental function approximation apparatus and method
Inventor: HENRY MATTHEW R
IPC: G06F17/17
Filed: 1992-07-02
Abstract: TRANSCENDENTAL FUNCTION APPROXIMATION APPARATUS AND              METHOD                          ABSTRACT OF THE DISCLOSURE Transcendental function approximation using a regional approximation look-up table, offset lookup table, scaling shifter and interpolation adder/subtractor. Rapid fixed-point arithmetic calculations can be accomplished which approximate values of transcendental functions to a predetermined accuracy. The invention accepts an N bit argument and produces an N bit result allowing the placement of the radix point in the two numbers to be different. Different parts of the input argument are fed in parallel to the regional approximation look-up table and the offset lookup table. A scaling shifter converts the output of the offset lookup table and regional lookup table to a result usable by the interpolation adder/subtractor processor. The regional approximation lookup table also provides information to the interpolation processor which provides the N bit approximation.

Abstract: A high frequency welding system for tubular members applies high frequency current I to the gap for creating an alternating field.   According to magnetic flux of the alternating field, an opposed current i is generated  in a  conductive portion of the welding apparatus.  In close proximity, inductance is effected between the welding current I and the response current i. An output  circuit  is  provided  for  generating high frequency current for establishing a welding heat with suppression of ripple current at the output.  The welding processing is observed by a CCD camera which is  in communication with an  image processing portion for analyzing image data for determining welding conditions. A signal from the image processing portion is output to a monitoring portion which continuously monitors welding operation and activates an alarm  if welding conditions exceed predetermined values.   A correction processing portion also receives  the  signal  from the  image processing portion and effects adjustment of the power circuit for maintaining a welding heat at a desired level.

IPC: B30B9/12
Filed: 1992-08-07
Abstract: Abstract of the Disclosure Apparatus  for  removing  heating  or  cooling fluid from a rotary heat exchange device defining a shell chamber with a longitudinal axis.   The exchanger desirably includes an inlet means for admitting a heat exchange fluid such as steam into the shell, and a shaft extending along the longitudinal axis, the shaft being at  least  partially hollow  so  as  to define  a  shaft chamber.

Each set of collecting members includes  first  and  collecting  members,  mounted  for rotation in unison with one another about the axis.  The first collecting member extends radially inwardly from the  inner  surface  of  the  shell,  and  the  second collecting  member  is  spaced  apart  from  the  first collecting member in a first circumferential direction so that the first and second collecting members of each set  define  a  collection  space  therebetween.    Each collection space communicates with the shell chamber at the  second  collecting  member  adjacent  the  interior surface of the shell.

Abstract: ABSTRACT                 (Figure 1 refers) A cylindrical oil-filled casing (2,3,5) has an input shaft (12) on which are mounted a pair of braking rings (17,26) which are allowed limited axial and circumferential movement with respect to one another. The ring (26) is driven by the shaft and drives the  other  ring  (17)  through  a  circle  of  angularly-spaced, spring-biassed  balls  (28)  mounted  in tear-drop shaped recesses in  the  opposed  faces  of  the  rings  (17,26).  Each  ring  has  a frusto-conical braking rim extending parallel to a frusto-conical braking  surface  (8,9)  provided  on  the  casing  part  (5).   The rims of the rings (17,26) have angularly-spaced, shallow, chordal segments  removed  to  provide  recesses  which,  during  rotation of  the shaft  (12),  pump oil  between  the braking surfaces of the   rings   and   the   casing,   to   form  hydraulic  cushions therebetween.  Reversal  of  the  shaft  torque   causes the balls (28) to force the rings (17,26) apart and into braking engagement with  the  casing  to  check  rotation  of  the shaft.  The  pumping action  of  the  recesses  diminishes  during braking so  that  the cushions collapse and do not impair braking.

Title: High-speed packet switch
Inventor: KANAKIA HEMANT R
IPC: H04L12/56
Filed: 1993-04-13
Abstract: High-Speed Packet Switch Abstract A packet switch of the type in which packets received in the switch are stored in memory until they are output. In the switch fabric of the switch, packets are serially received in input shift registers wide enough to store an entire packet, output in parallel to memory which is as wide as the input shift register, moved in parallel in the memory, and output in parallel to an output shift register. The bus connecting the input shift registers, the output shift register, and the memory is as wide as the input shift register, but does not cross the boundaries of the semiconductor chips making up the switch fabric, thus avoiding the electrical problems of very wide buses. In the disclosed implementation, there are 14 input lines and 14 output lines. A switch memory is associated with each output line and receives packets from all 14 input lines, accepting only those destined for the output line associated with the input line. Each switch memory includes a controller, memory and a communications interface for the controller, and a set of switch memory VLSI devices. Each switch memory VLSI device includes a first shift register for receiving slices of the packet and a bus, a memory, and a second shift register for outputting the slices. The bus, the memory, and the second shift register are as wide as the first shift register.     FILE kanhr002us.1 kanhr002us.CL kanhr002us.ab

IPC: B41F13/12
Filed: 1993-04-23
Abstract: In a rotary printing machine with directly driven cylinders and at least one directly driven folding unit (12), those drives of the cylinders and their drive controllers which can be assigned to a paper web are combined to form printing-station groups (2). The printing-station groups (2a-d) are connected to one another, to the folding unit (12) and to the operating and data-processing unit (1) via a data bus (3). Within the printing-station group (2), the individual drives of the cylinders and their drive controllers are connected via a high-speed bus system. The printing-station groups (2a-d) acquire their position reference directly from the folding unit (12). The master control system (1) is now responsible only for the presetting of desired values and desired-value deviations and the processing of actual values. The division of the overall control system into a master control system and autonomous printing-station groups (2) achieves that simplicity, flexibility and robustness in respect of faults which is necessary for producing a directly driven rotary printing machine.

IPC: A61B17/22
Filed: 1991-11-04
Abstract: A urethral insertable applicator for prostate hyperthermia includes an energy applicator (14) in association with a multi-tube, balloon-type catheter (18). The energy applicator (14) may be a microwave applicator or an ultrasound applicator, either of which, when inserted in the prostate, will cause heating of the prostate tissue surrounding the applicator. The applicator (14), with a radiometer (11), may serve as a means to measure temperature by measuring the thermal energy radiated from the prostate tissue.  Provision may be made for circulating a cooling fluid through a cooling chamber (73) between the applicator (14) and the tissue to be heated. The difference in temperature of the inlet and outlet cooling fluid may also be used to indicate prostate tissue temperature. A measure of the temperature of the prostate tissue being heated is used to control application of energy to the applicator.
