Title: Universal Toilet Fish with Inflatable Ending
Inventor: PLUDOWSKI ROBERT
IPC: E03D9/00
Filed: 1994-05-20
Abstract: The aim of this invention is to provide universal toilet fish which will be able to remove all the objects which might fall into the toilet. At present not all the objects may be removed from the toilet bowl by means of the flexible spring. Flexible spring has no means to attach itself to such an object like a small bottle or hockey puck. Therefore their removal becomes impossible. The only way of removing of such an object from the toilet bowl is to unscrew the toilet bowl, drain it from water, turn it upside down and shake hoping that the object will dislodge itself and fall off. With the old installations this often leads to damage to the tile file and damage to the lead connecting pipe increasing substantialy thecost of the repair. Universal toilet fish solves this problem. At the end of theflexible spring there is an inflatable baloon attached. This baloon is protected by the plastic cone which also facilitates its introduction into the toilet bowl. This baloon has a plastic pumping line which is lead in the center of the flexible spring to the crank of the flexible spring. On the crank this line is equipped with thebicycle valve. After the introduction of thus equipped flexible spring into the toilet bowl, the baloon must be inflated with the bicycle pump. The baloon expands closing the toilet bowl space chamber. By carefully withdrawing the flexible spring from the toilet bowl we remove all the objects trapped before the inflated baloon.

IPC: B01D3/38

Abstract: An apparatus and method for treating chemical production plant process condensate such that a contaminant-rich stream and a relatively pure aqueous stream is separately recoverable from the condensate, wherein the contaminants are substantially removed from the condensate by steam stripping and subsequent rectification in a relatively low pressure stripping/rectification tower. The tower overhead is then condensed with a portion of the condensed overhead being returned to the tap of the rectification section of the tower as reflux and the balance being withdrawn as a concentrated stream for reuse in the plant. In a second embodiment, separate stripping and rectification towers operate in series whereby the overhead of the stripping tower is delivered to the lower section of the rectification tower and the rectification bottoms are returned to the top of the stripping tower. The overhead from the rectification tower is then condensed with a portion returned at its top for reflux and the remainder being withdrawn as a highly concentrated stream for recycling to the ammonia plant. The mass flow to the ammonia plant is low enough because of high concentration that ammonia plant modifications are not needed nor is there significant thermal impact. The apparatus may be used in conjunction with existing low pressure equipment, avoiding costly major modifications.

IPC: H04N1/44
Filed: 1994-07-21
Abstract: Original source verifying data defining a first source verifying image are stored in memory. The first source verifying image can be produced by a human making marks by hand in a field of a form, which can then be provided by a scanner or a facsimile transmission through image input circuitry. If a second source verifying image is received that is the same as the first source verifying image, an operation is performed that would not be performed if the images were not the same, such as an operation accessing a related item of data. For example, the first source verifying image can be received with a document image, and data defining the document image and the original source verifying data can be stored so that a source verifying image that is the same as the first source verifying image must be received before an operation can access the document data and provide it to image output circuitry for printing or facsimile transmission. As a result, the marked form is analogous to a key: Only someone who possesses the marked form or a high quality copy can obtain access to the document data. If the marked form is lost or destroyed, the document data cannot be accessed.

Title: Novel oligonucleotide arrays and their use for sorting, isolating, sequencing, and manipulating nucleic acids
Inventor: CHETVERIN ALEXANDER B
IPC: C12Q1/68
Filed: 1993-02-19
Abstract: The present invention relates to new oligonucleotide arrays and methods of using oligonucleotide arrays. Binary oligonucleotide arrays, having binary oligonucleotides characterized by a constant nucleotide sequence adjacent to a variable nucleotide sequence, are used for sorting and surveying nucleic acid strands.  Oligonucleotide arrays are used for sorting mixtures of nucleic acid strands, making immobilized partial copies of nucleic strands, ligating strands, or introducing site directed mutations into strands.  Information is obtained for determining the sequence of a nucleic acid strand, alone or in a mixture, by generating partials of the strand and, for groups of partials having the same terminal variable oligonucleotide, separately determining the presence and sequence of all variable oligonucleotides. Arrays are also used to order previously sequenced nucleic acid fragments and to allocate ordered allelic fragments to chromosomal linkage groups.

Title: Method and apparatus for row-wise separation of rectilinear, plastic porous concrete bodies
Inventor: HARTMANN WILFRIED
IPC: B65G59/08
Filed: 1995-01-06
Abstract: In this method for row-wise separation of rectilinear, plastic porous concrete bodies these are formed by longitudinal and transverse cutting of a rectilinear,plastic porous concrete block preferably standing on edge. After turning back through 90° the cut block is so placed with its major side surface on a plurality of parallel laminae for the separation that its longest side edge runs parallel to the direction of the laminae and that reach row of porous concrete bodies is supported on at least one lamina. Before the separation a clamping force is exerted from above on the upper ends of all the porous concrete bodies of the row to be separated independently thereof from above on the upper ends of all the porous concrete bodies of the stationary row in contact with the row to be separated. This clamping force is maintained during the separation and during the displacement of the lamina in the separating direction, a like directed displacing force is exerted synchronously on the upper ends of the porous concrete bodies carried by the separating lamina.

Filed: 1995-11-10
Abstract: STM traffic, e.g. voice and video telephony (VT), as well as packet mode (e.g. ATM) traffic, e.g. broadcast digital video, interactive television, and data, are transmitted via a multiple access broadband fiber/coaxial cable network. Customer premises equipment (CPE) at stations, and a bandwidth controller, which may be at a head end or central office, with which all stations communicate, work together to adapt to the changing demands of the traffic mix, and efficiently allocate bandwidth to a variety of bursty and isochronous traffic sources. The bandwidth allocation defines two types of time slots, STM and ATM, and divides each frame into two corresponding STM and ATM regions. The boundary between the regions can be changed dynamically. A contention access signaling channel is provided in the STM region, for call control and set-up requests. Within the STM region, the time slots can be of variable length and be allocated on a per call basis; the length of the time slots is proportional to the bandwidth requirement of STM calls. Within the ATM region, the time slots are of fixed length, each capable of accommodating one ATM cell. Further, the fixed length ATM time slots may be reserved for a particular user for the duration of a call, or may be shared through a contention process. At least one contention ATM time slot is always made available for signaling messages related to ATM call control and set-up requests. The downstream time frame is structured in a similar manner, but includes an additional MAP (slot allocation mapping) field to transmit to the stations ATM time slot allocation and status information for time slots in the upstream channel.
