Title: Disk-type decker
Inventor: KRIEGER UWE
IPC: B01D33/15
Filed: 1988-09-15
Granted: 1994-05-17
Abstract: Abstract In a disk-type decker that is employed to drain suspensions and that has axially distributed suspension chambers and filtrate chambers that are separated by rotating screen disks and open into a stationary tub, the filtrate chambers are evacuated to increase the throughput of the decker and improve and accelerate drainage.  The filtrate chambers are for this purpose divided by radial and axial transverse partitions into individual filtrate-chamber sections distributed along the circumference and sealed off from one another.  When the screen disks and hence the filtrate-chamber sections rotate and the sections enter into flow engagement with filtrate outlets at the bottom of the decker, they are simultaneously evacuated, accelerating drainage through the disks.  The results are a higher throughput, a lower material density in the filtrate, and lower specific investment costs at the same throughput or material density in the filtrate.  The filtrates can be separated because the filtrate outlets are divided along the circumference.

Abstract: ABSTRACT OF THE DISCLOSURE A  transmitter        for  use  in  a  process control  system has  externally  accessible  actuators for permitting external adjustment of the zero and span  (or  full  scale)  settings  of  the  transmitter .   the  transmitter       has  an explosion-proof housing        which  includes  an  interior  chamber in which  transmitter circuitry is  located. Each  of  the  actuators  includes  a  movable  magnet which  operates  a  magnetic  reed  switch located within the interior chamber      of the housing      through a wall      of the housing .   Each of the magnets           is mounted on a movable actuator           which extends into a blind hole            in a wall       of the housing    . By moving the magnet    within its hole ,  the  corresponding  reed  switch can be changed from a non-actuated to an actuated state.  When the zero reed switch       is actuated, the transmitter circuitry adjusts its output so that the  present  value of  the  parameter  represents  a process zero.  When the span  (or  full  scale)  reed switch        is actuated,  the transmitter circuitry adjusts its output so that the present value of the sensed parameter represents a process maximum.

Granted: 1993-08-03
Abstract: TITLE OF THE INVENTION         A Speech Signal Coding/Decoding System ABSTRACT OF THE DISCLOSURE   input  speech  signal  is  encoded by an adaptive quantizer  (16)  which quantizes  the predicted residual signal  between  the  digital  input  speech  signal,  and prediction signals provided by predictors (6,10) and a shaped quantization noise provided by a noise shaping filter (19). An inverse quantizer (18) which the encoded speech  signal  is  supplied  to,  is provided  for noise shaping and local decoding.  A noise shaping filter (19) around the adaptive quantizer makes the spectrum of the quantization noise  similar  to  that  of  the  original digital input speech signal by using the shaping factors.          The shaping factors (rn1, rns) set to the noise shaping filter  (19)  are  adaptively  switched  to  weight  it depending upon the prediction gain (ex. ratio of input speech  signal  to  predicted  residual  signal  or  the prediction coefficients).   In a decoding side there are an inverse quantizer (36), predictors (42,43), and a post noise shaping filter (44). The shaping factors set to the post noise shaping filter are similary switched to weight it depending upon the prediction gain.

Abstract: Abstract Of The Disclosure A fiber optic coupler is formed by providing a glass tube having a longitudinal aperture extending therethrough. Glass optical fibers, each having a core, cladding and coating are disposed within the longitudinal aperture, the fibers extending beyond each end thereof.  The coating is removed from that portion of the fibers in the midregion of the tube but remains on that portion of the fibers extending into the ends of the apertures.  The coating can be removed prior to inserting the fibers into the tube, or it can be removed from that portion of the fibers in the midregion of the tube by oxidation, depolymerization or the like.  The aperture is formed by a plurality of flattened walls, the dimensions and orientations of which are such that the cross-section of the aperture in the central region of the tube is symmetrical with respect to a plane passing through the longitudinal axis of the tube.  At any cross-section of the aperture that is adjacent the coated regions of the fibers, each fiber coating contacts two walls of the aperture. The fibers are held taut to effect a tension therein, and the midregion of the tube is heated, collapsed about the fibers, and drawn to reduce the diameter thereof over a predetermined length.

Abstract: ABSTRACT   This invention relates to an electrochemical cell having spirally wound electrodes and an electrolyte which enhances plating of the anode metal during voltage reversal.  The safety of such cells is improved by concentrating the current, during voltage reversal, between an outer segment of the anode and a metal sheet connected to the cathode whereby anode metal plates only onto the metal sheet.  Thus, the hazardous condition of plating anode metal onto the cathode is avoided.

Abstract: Optical interference structures incorporating porous films are disclosed.  These structures are capable of exhibiting a colour by interference effects caused by the interference of light reflected from various layers within the structure.  Basically, the structures comprise a reflective substrate, a porous transparent dielectric film on the substrate and at least one semi-transparent layer supported by the porous dielectric film.  The structure is such that there are at least two reflective surfaces separated by an optically thin porous layer of the dielectric film.  These structures can be formed by several methods, but the most convenient involves the porous anodization of a substrate metal (e.g. aluminum) to form the dielectric film and the deposition of a semi-transparent metal layer within the pores or on the film surface.  The structures can be made inexpensively and are capable of generating strong and, if desired, dichroic colours.  The porous nature of the film can also be exploited to create colour shifts.  The structures can be used for decorative purposes or to create a wide range of indicators, sensors, security devices and the like.
