Abstract: An umbrella comprising a central shaft having an upper end and a lower end with the lower end including a handle incorporates a plurality of pivotable members each having a first end pivotally coupled to an upper end of the shaft and being circumferentially spaced about the shaft and oriented generally parallel thereto when the umbrella is in a collapsed condition. A plurality of flexible members are operatively associated with corresponding ones of the pivotable members. The flexible members are each expandable into a generally hoop-shaped configuration adjacent another end of the pivotable members when the pivotable members are pivoted from a collapsed condition to an operative position. The open umbrella appears as a canopy stretched over a plurality of circumferentially spaced ribs with each rib terminating in a hoop-shaped member.

Abstract: A battery pack assembly is removably insertable into a receptacle on a housing of an electronic receiver carried by an animal to control the movement of the animal relative to a predetermined area. The battery pack assembly supplies power to the electronic receiver. The receptacle for the battery pack has internal guide grooves and detentes along the guide grooves. The battery pack has lugs which slide within the guide grooves to guide the battery pack into position within the receptacle. The detentes cooperate with the movement of the lugs to lock the battery pack in position within the receptacle housing. A spring contained within the battery pack biases the battery pack relative to the receptacle to prevent the battery pack from inadvertently disengaging from the housing.

Abstract: The invention relates to an apparatus for regulating the speed of an a.c. elevator motor (10) by means of a frequency converter (8) consisting of a rectifier bridge (4) and an inverter bridge (4). The frequency of the frequency converter is adjusted until it corresponds to a frequency reference (fref) corresponding to the speed reference (vref'vref') of the motor. The velocity of the motor (vreal) is measured to form a speed feedback signal. According to the invention, the apparatus comprises means (24,26) for correcting the speed reference (vref) on the basis of the change occurring in the voltage (Uc) of the intermediate circuit. <IMAGE>

Abstract: This invention relates to an improved process for the synthesis of 4-alkoxy-N-acetylneuraminic acids. According to the process of the invention, N-acetylneuraminic acid is first alkylated at C-1 and C-2 and then the vicinal hydroxyl groups at C-8 and C-9 are protected through the formation of a ketal. The resulting protected alkyl ester alkyl ketoside is then alkylated at the C-4 position whereby the hydrogen of the C-4 hydroxyl group is replaced with an alkyl group to form an alkoxy group. Deprotection is accomplished through the removal of the ketal group at C-8 and C-9 and removal of the alkyl groups at C-1 and C-2, thereby producing the 4-alkoxy-N-acetylneuraminic acid.

Abstract: A suspension of animal cells is incubated with supports to adhere the cells to the supports. Preferably, the supports have pores that provide pore volume, and the cells are grown during incubation until most of the available pore volume is filled with cells. An encapsulating layer is then formed around the supported cells by exposing the cells on the supports to a reactive gas composed of a carrier gas such as sterile air saturated with an inorganic alkoxide followed by treatment with steam to hydrolyze residual alkoxide groups. The encapsulated cells are stored by immersion in culture media. The cells may be in the form of cell aggregates, and the supports can be sterilized. The supports and encapsulating layer can have pores of a size that permit free exchange nutrients and metabolic products, and excludes the cells from contacting antibodies or immune cells when implanted. The encapsulated cells can used in an extracorporeal device or implanted directly.

Abstract: The converter includes a read amplifier which has a first amplification stage which converts voltage variations across the terminals of a read diode into current variations. The gate of a MOS transistor is connected to the read diode and the other terminal is connected to ground. A second amplification stage connected in common base configuration reads the current variations. The common base amplifier consists of a bipolar transistor with base connected to ground via a capacitor. The base is connected to a voltage which is controlled so the transistor operates in active mode. The emitter is connected to the source of the MOS transistor and a first terminal of a current generator. The second terminal is connected to ground. The collector is the output of the read amplifier and is connected to a supply voltage via a resistor.

Abstract: Rotary disc filtration devices and filtration processes using those devices are disclosed. The devices have one or more fluid filtration gaps into which fluid to be filtered into permeate and retentate is placed. Each fluid filtration gap is defined by a disc and a filter, one of which rotates with respect to the other. The filter is carried on a filter member. The discs and interleaved filter members may be suspended from the top of the device, the top may rest on a vessel containing the fluid to be filtered, the discs may be attached to a single shaft for rotation, and the filter members may be suspended from a sleeve around the shaft, which sleeve keeps the filters centered with respect to the discs. Removal of the device's top removes the discs and filter members together, facilitating maintenance. Each filter member may have a peripheral lip and the lips of adjacent filter members may be sufficiently close to one another to substantially restrict the flow of retentate out of the fluid filtration gap. Retentate flowing out of each fluid filtration gap may be directed into the vessel to counteract the tendency of the fluid in the vessel to rotate in the same direction as the discs are rotated, or the retentate may be recycled directly to the fluid filtration gaps. The liquid level in the vessel may be held constant using a dual-pipe system and three-head peristaltic pump.

Abstract: An ink cartridge for ink jet use is provided with an aperture for filling in the cartridge with ink. The circumference of the aperture and a part of a plug pressed in the aperture are fused and welded to be formed integrally to airtightly close the aperture, and obtain an integrated structure without any interface. Hence, it is made possible to reliably prevent ink from leaking therefrom, even if some scratches and cracks are present on both of them. This contributes to eliminating inspection steps to find ink leakage in the course of manufacture, and also, contributes to improving the yield of production. As a result, a significant reduction of costs is possible, while enhancing the reliability of the ink cartridge. <IMAGE>
