Title: Device for dividing or separating fillets
Inventor: HOLZHUTER ANDREAS
IPC: A22C25/18
Filed: 1990-07-18
Abstract: ABSTRACT            In an apparatus for dividing fish fillets of the type as shown e.g. in German Patent 36 23 002 there is used a sorting device, the aim of which is to sort automatical-ly fillet pieces gained under the aspect of predetermin-ed geometric or volumetric properties.  To this end, a connecting conveyor is arranged downstream of a belt con-veyor of the dividing device leaving a space therewith, in which space is installed a set of flap elements which can be swivelled about a common axis by single activa-tion.  In their activated position these function as a transfer chute between the said conveyors, whereas, in their rest position, there remains a discharge shaft downstream of the belt conveyor of the dividing device. The selection of the flap elements to be activated occurs in accordance with a predetermined programme, which makes said selection in accordance with the respec-tive cutting position of the cutting elements of the di-viding device and, if necessary, controls these elements with respect to the time parameters.

Title: Method and system for continuously monitoring and controlling a process stream for dechlorination residual
Inventor: VAN GROUW ALBERT III
IPC: G01N33/18
Filed: 1991-04-09
Abstract: METHOD AND SYSTEM FOR CONTINUOUSLY MONITORING AND CONTROLLING A PROCESS  STREAM FOR DECHLORINATION RESIDUAL     Abstract of the Invention A method and system for directly monitoring and controlling a continuous process stream for dechlorination residual is provided.  A sample stream to which a dechlori-nation  agent  has  been  added to  completely  eliminate  a residual  disinfectant,  is  continuously  drawn  off.    An analyzing agent,  different from the disinfectant,  in an amount in excess of that needed to completely react with the dechlorination residual, is added to the sample stream to leave an unreacted amount of analyzing agent.   Suffi-cient time is provided for the analyzing agent to complete-ly react with the dechlorination residual.  Thereafter, the sample stream is continuously analyzed to determine the amount  of unreacted  analyzing  agent  remaining  in  the process sample.   Based on the amount of analyzing agent added to the process sample and the amount of unreacted analyzing agent remaining in the sample after reaction, the amount of dechlorination residual is continuously deter-mined.   The amount of dechlorination agent added upstream to the process stream is continuously selectively varied using  the  determined  amount  of  dechlorination  residual present in the process sample.     7833-3 (CIP)1

Title: Equalizer for radio receive signal
IPC: H04L25/03
Filed: 1991-07-05
Abstract: In  a  transversal  type  equalizer having a  series connected delay elements, multipliers coupled with each output of  each delay element and an adder for adding outputs  of  said  multipliers  to  provide  an  equalized output signal for equalizing time division radio receive signal for every burst in mobile communication, a receive memory  (11)  for  storing receive signal,  a transversal type  equalization  process  circuit  (77a)  coupled  with output of said memory (11), and an output memory (100) for  storing  equalized output  signal  are  provided.  In training tap coefficients of a transversal filter, a tap or a delay element is precluded when an absolute value of a tap coefficient is less than a predetermined value, so that calculation amount for updating tap coefficients is decreased and tracking characteristics are improved;  a multiplier  (15)  is inserted between an output of said receive memory  (11)  and an input of said equalization process circuit (77a) so that a signal which is subject to  equalization  is  phase-shifted  beforehand  so  that frequency  offset  between  transmit  frequency  in  a transmitter  and  local  frequency  in  a  receiver  is compensated. The phase adjustment by said multiplier (15) depends upon  residual  phase  error at output of  said equalization  process  circuit (77a);  an  output  memory (100) is used as a training signal to initialize the tap coefficients of said equalization process circuit (77a) during a burst when equalized output signal has error larger than a predetermined value.

Title: Colour-matching of coatings
Inventor: MCMINN KENNETH R
IPC: B05D7/24
Filed: 1991-09-25
Abstract: A process for the sequential coating of an object with at least one undercoat and then at least one pigmented topcoat is disclosed. The undercoat is formed by admixing at least two compositions to form the undercoat, the compositions having different reflectance values and having a colour selected from white, grey and black. The admixing is controlled so that the undercoat composition has a reflectance value of ~10, preferably ~5, units of the reflectance value of the topcoat. The process reduces the number of coatings or the amount of film build of topcoat in order to achieve efficient colour match of topcoat. The process is particularly useful in the automotive industry, especially the refinish portion of that industry.

Title: Adhesives and method for making same
Inventor: DORSEY GEORGE F
IPC: C09J175/04
Filed: 1990-06-27
Abstract: A thermosetting mixture for use as an adhesive, as well as other applications, that is substantially nonmutagenic. This mixture is based upon a thermosetting resin selected from polyurethane and epoxy resins, using an improved curing agent that does not contain mutagenic components. Specifically, the curing agent is a multi-mixture of substituted alkylanilines produced by an improved process. These alkylanilines are formed by condensation of at least two alkylanilines with a formaldehyde in an acid solution. Upon purification, at least three aromatic diamines are formed that are used for the curing agent with the polyurethane and epoxy resins. Pot life, green strength and ultimate strength are comparable to adhesives of the prior art that contain mutagenic constituents.  Although several dialines are described, the preferred curing agents are formed using 2,6-diethylaniline (DEA) and 2,6-diisopropylaniline (DIPA), where the mole % of DEA and DIPA is 38-48 and 62-52, respectively. Curing agents within the preferred range have been designated as "Asilamine 4852" and "Asilamine 4555".

Abstract: ABSTRACT       Disclosed is a keypad for use with compact and portable cellular telephone systems in which each key is backlit. A partially translucent overlay layer of flexible material includes a raised key. Under the key, in a preferred embodiment, is an actuation layer, which, during operation, is depressed downward by the key. Below the actuation layer, is a tactile feedback layer including a dome for each key, in which, after being depressed to a predetermined degree, the dome inverts causing a conductor located below the dome to short conductive traces on a substrate upon which the keypad is mounted. In a preferred embodiment, the keys are backlit by a light source extending through the substrate upon which the keypad is mounted.  The tactile feedback layer includes a structure for reducing pressure on the light source when the tactile layer is in the inverted condition, resulting in a thinner keypad with a brighter backlit key and a longer life light source.
