Abstract: CASE 2439 "METHOD FOR THE DETERMINATION OF ANTI-P. FALCIPARUM SPOROZOITE ANTIBODIES IN HUMAN BLOOD" Abstract An immunoenzimatic method is disclosed for the detection and the measurement of anti-P. falciparum sporozoite antibodies in human blood and/or in its derivatives, which operates with a synthetic antigen-enzyme conjugate capable of forming with the antisporozoite antibodies a stable antibody-synthetic antigen-enzyme complex, and one or more proteins adsorbed and/or covalently linked to a solid support, which eagerly bind the antisporozoite antibody of said complex. The method, thanks to its simpleness, specificity and rapidity, is particularly useful in epidemiologic investigations into malaria and into the efficacy of an antimalarial vaccine.

Abstract: ABSTRACT OF THE DISCLOSURE    A passenger vehicle polling system. The system is capable of polling one or more terminal units, where each terminal unit is provided at a different one of a plurality of passenger seats in a passenger vehicle, to obtain information indicative of the state of each terminal unit. The polling is accomplished by transmitting a polling command signal from a head end apparatus through a transmission line to the terminal units. Preferably, a sensor is mounted adjacent each passenger seat to sense the status of the passenger seat. The sensed information is transmitted as a polling answer signal through the transmission line to the head end apparatus so that the status of each passenger seat and the condition of each passenger can be checked from the head end apparatus. Further, a system according to the invention may transmit audio and video programs to the terminal units, and the polling answer signal may indicate which audio or video program has been selected at each terminal unit.

Title: Episomal vector for the expression of selected dna fragments coding for optional polypeptides in mammalian cells and methods for the production thereof
Inventor: ISMO JOHANNES U
IPC: C12N15/869
Filed: 1988-05-19
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is directed to an episomal expression vector with an efficient expression potential of cloned DNA sequences.  The single vector plasmid of this invention joins DNA-fragments, which allows extra chromosomal replication of the vector in a wide selec-tion  of  host  cells  and  fragments,  which  give  the transfected cells resistance for a selection drug and a mammalian  expression  cassette  comprising  one  of  the strongest eucaryotic enhancers known at present.   The vector also carries appropriate promoter and transcrip-tion processing signals.  This new combination provides this expression vector with  several  properties  that makes it optimal to be used in transfection of cell lines suitable for production and expression of foreign cDNAs joined into this vector with high efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention concerns a spin basket clutching device which includes a flotation device which locks the spin basket to an agitator in response to the level of wash liquid in the basket.  During a wash step, the basket will be full of liquid and the flotation device floats within an inverted pocket located on the agitator skirt.  During a spin step, the basket will be empty of liquid and the flotation device will drop partially out of the inverted pocket and rest partially within a pocket on the spin basket, thus locking the agitator to the spin basket for concurrent rotation.  Also disclosed is a device which responds oppositely to the level of wash liquid in the wash tub locking the spin basket to the wash tub to prevent rotation of the basket during agitation of the wash liquid by the agitator during the wash step and unlocking the basket from the tub in a low liquid level step such as spin.

Title: Image sensing apparatus having automatic focusing function for automatically matching focus in response to video signal
Inventor: KIKUCHI KENICHI
IPC: H04N5/232
Filed: 1989-05-10
Granted: 1993-05-11
Abstract: ABSTRACT OF THE DISCLOSURE     In a video camera having an automatic focusing function, a first sampling area in the center of an image sensed picture and a second sampling area around the first sampling area are set.  Considering a case in which an auto-focus operation is carried out selecting the first sampling area as a focusing area, when the difference between the newest focus evaluating value and the maximum focus evaluating value becomes one-eighth or more of the maximum focus evaluating value, the second sampling area is selected as the focusing area, to carry out an auto-focus operation.  Consequently, an auto-focus operation conforming to the state of an object is carried out.  In addition, a priority area for exposure control is selected following selection of the focusing area.  Thus, exposure relative to a main object is always maintained most suitably.  Furthermore, even if the focus evaluating value has no distinct peak, the erroneous detection of the in-focus position can be prevented since the sampling area having a larger maximum value per unit area is selected as a focusing area.
