Title: Identifying, isolating and cloning messenger rnas
Inventor: LIANG PENG
IPC: C12N15/10
Filed: 1993-03-11
Abstract: A method for isolating mRNAs as cDNAs employs a polymerase amplification method using at least two oligodeoxynucleotide primers.  In one approach, the first primer contains sequence capable of hybridizing to a site immediately upstream of the first A  ribonucleotide of the mRNA's polyA tail and the second primer contains arbitrary sequence. In another approach, the first primer contains sequence capable of hybridizing to a site including the mRNA's polyA signal sequence and the second primer contains arbitrary sequence. In another approach, the first primer contains arbitrary sequence and the second primer contains sequence capable of hybridizing to a site including the Kozak sequence. In another approach, the first primer contains a sequence that is substantially complementary to the sequence of a mRNA having a known sequence and the second primer contains arbitrary sequence. In another approach, the first primer contains arbitrary sequence and the second primer contains sequence that is substantially identical to the sequence of a mRNA having a known sequence. The first primer is used as a primer for reverse transcription of the mRNA and the resultant cDNA is amplified with a polymerase using both the first and second primers as a primer set.

Title: Energy efficient insulation system for refrigerator/freezer
Inventor: CUR NIHAT O
IPC: F25B5/02
Filed: 1993-08-12
Abstract: A refrigeration appliance having at least two refrigeration compartments, each compartment having its own access door, is provided wherein there is a first evaporator for the first compartment, the first evaporator operating at a first pressure level and a second evaporator for the second compartment, the second evaporator operating at a pressure level higher than the first pressure level. There is a control device for directing refrigerant to a selected one of the evaporators from a condenser and for preventing a flow of refrigerant into the first evaporator when refrigerant is being directed into the second evaporator to cool the second compartment. Around the first compartment is placed insulation having a higher thermal resistance than that placed around the second compartment since the first compartment is kept at a lower temperature that the second compartment. A phase change material may be used in association with one or both of the evaporators.

Title: Form reader with linear ccd scanner and drum feed
Inventor: CANNON THOMAS
IPC: G06K19/00
Filed: 1992-05-28
Abstract: A form reader especially for lottery forms with handwritten marks or bar codes includes a drum transport (52) engaging the form, and a stepping motor advances the form circularly along a path around the drum, passing through a linear reading station elongated perpendicularly to the path. A light source (90) illuminates the form at the read station and reflected light is incident on an elongated array of charge coupled device (CCD) light sensors via a focusing lens arrangement (122). An analog comparator coupled to a serial output of the CCD sensors digitizes and encodes each pixel in the elongated array repetitively during transport, sampling the reflectance of the form and defining an X-Y array of pixels.  A digital processor coupled to an image memory analyzes the data for predetermined patterns such as handwritten marks, printed reference marks and/or printed bar code or OCR characters on the form. A throat sensor detects the form at an inlet to the reader for initiating operation of the stepping motor when the form is present. Form guides align the form generally to the transport path, and can be laterally movable for aligning one or both edges of the form to the transport path.

Abstract: An insulating unit (150) has a pair of glass sheets (12,14) about an edge assembly (152) to provide a compartment (18) between the sheets. The edge assembly has a U-shaped spacer (158) made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs (156) of the spacer (158) and the glass (12,14) provide a long diffusion path to limit the diffusion of argon gas out of the compartment (18). The edge assembly (152) has materials selected and sized to provide edge assembly having an RES-value of at least 75. A spacer (158) for use in insulating units includes a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit (150) and spacer (158). The unit (150) has a long diffusion path to increase the time period in which insulating glass e.g. Argon gas may be retained in the compartment (18). The increased RES-value provides a unit (150) that has a low thermal conducting edge (152). In this manner heat loss through the marginal edge (152) of the unit (150) is reduced. <IMAGE>
