Patent EP-0322115-A3 (EP)
Title: Genetic detoxification of pertussis toxin
IPC: C07K19/00
Filed: 1988-11-24
Abstract: A new method is described for the preparation of a safe, immunogenic and efficacious vaccine for protection against the disease pertussis. In development of this vaccine, specific functional sites of pertussis toxin have been identified, and using this information, defined mutant holotoxins have been produced by site directed mutagenesis of the toxin gene. A number of these toxin analogues are detoxified, retain an immunodominant S1 epitope, are immunogenic and are protective in the standard pertussis vaccine potency test in mice. Mutant strains of B. pertussis are described from which the native toxin operon has been deleted and replaced by a mutant gene which expresses the mutant holotoxins. The native TOX operon of a specific B. pertussis strain has been isolated, sequenced and cloned into plasmid DNA.

Title: Container and blank for, and method of, microwave heating
IPC: B65D81/34
Filed: 1989-10-16
Abstract: A susceptor bag (20) for microwave heating of food 
products, such as french fries, fish sticks, apple 
turnovers and burritos, is formed from a single flexible 
sheet comprising a layer (16, 28) of metal or other 
electroconductive material having microwave susceptor 
thickness, supported on a paper substrate material (12, 
24). The flexible sheet is folded on itself to form a 
sleeve (20) which houses and engages the food product.

Title: Method and apparatus for operating a refrigeration system
IPC: F25B47/02
Filed: 1989-10-20
Abstract: A refrigeration system (10), and method of 
operating same, in which an economizer heat exchanger 
(34), normally used in conjunction with an intermediate 
port (IP) of a refrigerant compressor (14) to cool the 
main refrigerant flow from a receiver (20) to an evapora­
tor (22) to enhance the refrigerant cooling cycle, is 
caused to function as an evaporator during a hot gas 
heating cycle. The economizer heat exchanger (34) is 
caused to function as an evaporator by adding heat thereto 
during a heating cycle, and by establishing an alternate 
liquid line (60), effective during a heating cycle, which 
includes the economizer heat exchanger. When the 
compressor (14) is driven by an internal combustion 
engine (15), engine coolant may be used to add the 
necessary heat to the economizer heat exchanger (34)

Patent EP-0376454-A3 (EP)
IPC: G01G11/04
Filed: 1989-11-09
Abstract: A mechanism for transporting flat articles (130), such as 
envelopes, onto and across the tray (36) of a scale (12). A belt (110) is 
trained about a combination of rollers (74) received within slots (38) of the 
tray (36) which, in combination with flaps (120) supported by the tray, are 
used to transport a flat onto the weighing scale. When a flat is to be 
weighed, it is transported onto the tray (36), the rollers (74) are 
withdrawn below the tray by an increase in tension in the belt (110) and 
the flaps (120) hold the flat (130) securely against the tray. The tray (36) 
is then oscillated by an electromagnet (37) and the weight of the flat is 
determined from the harmonic period of oscillation. Upon completion of 
weighing, the tension in the belt (110) is reduced to permit the rollers (74) 
to rise back above the tray (36) to remove the flat from the tray.

Title: Photographic image reproduction using digital halftoning
IPC: H04N1/405
Filed: 1991-02-06
Abstract: In the generation of screened halftones of photographic images for low resolution marking devices, conventional screen techniques are too coarse, and adaptive dither techniques are too fine.
