Title: Method and device for spraying on jelly
Inventor: COENMANS FRANK
IPC: A21D13/17
Filed: 1990-04-02
Abstract: ABSTRACT         There is disclosed a method and device for putting jelly on a pastry or the like.  Ready-mixed jelly is put in a container and kept there, at a temperature under about 60 °C; that from there, as much jelly as is needed for the intended purpose is led to a place where it is heated to a temperature at which it jellifies, and when that temperature is reached, the jelly is put on the pastry.  The device described for realizing the method consists of a unit, containing a hermetically sealable container for the ready-mixed jelly, which is provided with an opening for building up the pressure in the container and with an outlet through which a pipe is stuck which discharges into the jelly, and also containing a container for the warm water with an inlet opening which on the outside is connected with the outlet of the container, and which on the inside is connected via a heat-conductive tube of relatively great length, with an outlet and an instrument, cooperating with that outlet, which puts the jelly on the pastry.

Title: Method for data distribution in a disk array
Inventor: SCHULTZ STEPHEN M
IPC: G06F3/06
Filed: 1990-11-02
Abstract: Abstract For use with a computer system having an intelligent mass storage disk array subsystem, including a microprocessor controller, a method for the distribution of data within the disk array based upon logical commands issued by the computer system. The disk controller reads a logical command and translates the commands into multiple drive specific commands, including drive physical parameter information such as head, sector and cylinder selection. The calculation of these physical parameters is based upon a number of factors including the operating system installed in the computer system, the type of interleave scheme, if any, specified by the computer system configuration, and disk specific parameters. The physical drive requests are then placed in a queue and executed by the microprocessor controller. The method also encompasses a method for creating a disk array configuration to be loaded on all disks within the array based on existing valid disk array information and configuration information maintained by the computer system.

Title: Active muffler with dynamic tuning
Inventor: GEDDES EARL R
IPC: F01N1/06
Filed: 1991-03-26
Abstract: ABSTRACT      A method and apparatus for muffling motor vehicle engine noise comprises conventional noise attenuation apparatus and techniques as well as a tuning circuit for delivering separate signal outputs to at least two transducers separated along the length of the exhaust conduit.  A spacing between the trans-ducers corresponds to the range of tuned exhaust lengths required at various engine speeds within the operating range of the motor vehicle engine.  The tuning circuit varies the strength of the signal de-livered to each of the transducers to vary the cancel-lation point within the conduit so as to vary the effective length of the conduit in a manner that main-tains a minimum or negative pressure pulse at the valve exhaust port and aids in the exhaustion of com-bustion gases from the cylinder.  As a result, engine performance is improved throughout the operating range of the motor vehicle engine.

Title: Conjugate recovery binding assays and devices
Inventor: CHING SHANFUN
IPC: G01N33/543
Filed: 1991-05-03
Abstract: ABSTRACT   The novel analytical devices and methods of the present invention involve a solid phase material, such as a test strip, through which a test sample and a conjugate travel and sequentially contact at least two defined sites for the comparative display of immobilized conjugate. The two defined sites of the present invention include a capture site to which is attached a capture reagent and a conjugate recovery site to which is attached a conjugate recovery reagent. The immobilization of conjugate in these sites is relative to the amount of analyte in the test sample. As the amount of analyte in the sample increases, there is a decrease in the detectable conjugate at the capture site and a corresponding increase in detectable conjugate at the conjugate recovery site. The devices and methods can be used for detecting the presence or amount of an analyte in a test sample containing or suspected of containing the analyte of interest. Optionally, a polyvalent conjugate can be used.

Title: System and method for displaying trimmed surfaces using bitplane masking
Inventor: EINKAUF MARK A
IPC: G06T15/30
Filed: 1991-10-04
Abstract: SYSTEM AND METHOD FOR DISPLAYING TRIMMED    SURFACES USING BITPLANE MASKING                       ABSTRACT     A system and method is provided for displaying trimmed surfaces  on  a  computer  graphics  system.   The  present invention  tessellates  a  three-dimensional  surface  into triangles and determines whether a trimming curve intersects any  triangles.   If  an  intersection  occurs,  a  polygon trimming  mask  is  formed  by  performing  an  exclusive  OR operation and rendering the polygon into a mask plane.  The XOR operation sets the bits in the mask plane corresponding to the trimming mask to logical 1.  The rendering hardware then compares the bits in the mask plane with the bits in the frame buffer and draws those pixels which correspond to the bits set to 1 in the mask plane.  Since,  the trimming mask  is  a  polygon  the  rendering  hardware  can  perform shading,  or lighting calculations using values for points which are contained on the tessellated triangle.   In this manner,  consistent  lighting of a trimmed surface can be achieved. Additionally, the present invention provides for the  formation  of  multiple  trimming  masks  when  multiple trimming  curves  intersect  a  tessellated  triangle.   The multiple trimming masks are sequentially XORed into the mask plane and the corresponding pixels are then drawn.
