Title: A single step purification of recombinant human interleukin-5
Inventor: NICHOLSON DONALD
IPC: C07K14/54
Filed: 1995-03-14
Abstract: Disclosed is a method for purifying Human interleukin-5 (IL-5) a single chromatographic step. After removing cells from a cell culture expressing human interleukin-5, IL-5 is purified by first adjusting the culture supernatant to the calculated pI value of mature IL-5 (pI = 7.44) and then passing the conditioned supernatant through tandem linked anion- and cation-exchange columns. The resulting pass-through fraction contains the IL-5 and is devoid of all other contaminating proteins. An optional hydrophobic-interaction chromatography step is disclosed for positive selection of IL-5 and in order to concentrate the preparation. Pure IL-5 was recovered with a high overall yield (>90%), was N-glycosylated and was entirely homodimeric.

Abstract: A cooling system for an engine is disclosed. The engine has a plurality of cylinder bores which are arranged along a longitudinal axis thereof. First and second coolant passages continuously extend along the periphery of the bores on each side of the axis, from the bore located in one end of the engine to the bore located in the other end of the engine. The first and second passages are connected to each other by a connector at one end of the engine. A connecting passage is formed in each of a series of intermediate walls, which are formed between adjacent bores, for connecting the first and second passages. Water as a coolant flows from an inlet, which is formed at another end of the first passage, through, in turn, the first passage, the connector, and the second passage, and flows out from an outlet, which is formed at another end of the second passage. Also, water flows through the connecting passages.

Title: An inflatable resuscitation device
Inventor: GRAY THOMAS C
IPC: A61M16/20
Filed: 1993-09-23
Abstract: A pulmonary resuscitator is set forth of the type having a compressible bladder to be depressed to supply air to a mask. Both the compressible bladder and mask have integral therewith a network of inflatable tubes which when pressurized resiliently rigidify the bladder and mask to establish nominal erected bladder and mask shapes.  The bladder has an inlet check valve and the mask has an outlet check valve where the outlet check valve utilizes a flapper valve for permitting flow of fluid into the mask upon depression of the bladder. Exhaust ports are located adjacent the flapper valve and are closed by the flapper valve when the bladder is depressed.  The exhaust ports are opened when the flapper valve closes as the bladder returns to its nominal shape after being depressed.  An air spring contained within the bladder chamber is in fluid communication with the network of inflatable tubes and through limiting orifices controls the rate at which the bladder returns to its nominal shape after depression.

Title: Electronic vacuum cleaner control system
Inventor: HOEKSTRA PETER
IPC: G05F1/00
Filed: 1995-05-11
Abstract: An electronic control system for a vacuum cleaner is provided that supports two-way communications between a microcontroller in the handle of the vacuum cleaner and a suction motor and various sensors in the canister of the vacuum cleaner.  The vacuum cleaner may be placed in one of two user-selectable bag change modes.  In a maximum suction bag change mode, the electronic control system of vacuum cleaner will shut off the vacuum cleaner when the vacuum cleaner bag has filled and the suction power of the unit has been degraded as a result.  If the maximum fill bag change mode is selected, the electronic control system will shut off the vacuum cleaner only after the bag has filled to the maximum extent allowable.  The control system has indicator lights to display to the user whether the maximum suction or the maximum fill mode has been selected.  The control system also has an optical dust sensor based on one-piece lens units located in the vacuum cleaner handle for monitoring the frequency with which dust particles flow into the vacuum cleaner.  The control system can automatically adjust the power setting of the vacuum cleaner based on the measured frequency.

Title: Transgenic fructan accumulating crops and methods for their production
Inventor: CAIMI PERRY GIRARD
IPC: C12N15/54
Filed: 1994-11-07
Abstract: This invention concerns methods for synthesis and accumulation of fructose polymers in seed, tubers or leaves of transgenic plants by selective expression of a bacterial fructosyltransferase gene. Selective expression includes coordination of timing, tissue specific expression and especially subcellular location. Successful transformants utilize sucrose to synthesize and accumulate fructan in the vacuole of the cell, in established crops, without loss of co-products or concern for yield loss due to degradation during maturation, harvest or storage of the plant. Enhanced fructan production will benefit the fructose sweetener industry and add value to grain used for feed.
