Title: Procedure for obtaining pneumococcnic polysaccharide imunogenetic protein conjugate
Inventor: KNISKERN J PETER
IPC: C12P19/04
Filed: 1992-01-27
Abstract: A novel conjugate vaccine comprising partially hydrolyzed, highly purified, capsular polysaccharide (Ps) from Streptococcus pneumoniae bacteria (pneumococci, Pn) linked to an immunogenic carrier protein, is produced by a new process. The conjugate is useful in the prevention of pneumococcal infections. Vaccines comprising a mixture of from one to ten different pneumococcal polysaccharideimmunogenic protein (Pn-Ps-PRO) conjugates induce broadly protective recipient immune responses against the cognate pathogens from which the polysaccharide components are derived. Young children and infants younger than 2 years old, normally unable to mount a protective immune response to the Pn-Ps alone, exhibit protective immune responses upon vaccination with these Pn-Ps-PRO conjugates.

Title: Arrangement for protecting documents or objects closed into container provided with protection
Inventor: DEVAUX FRANKLIN
IPC: E05G1/00
Filed: 1990-07-17
Abstract: The invention concerns a system for protecting documents or valuables, particularly articles such as bank notes, cheques or bank cards enclosed in at least one physically tamper-proof container, i.e a small box (1) which, in the event of being attacked, destroys them using suitable means, the system being characterised by the fact that the operating cycle of the small box (1) comprises a limited number of logical states, called modes, the transition from a first to a second mode being the consequence of a specific event, the licit nature of which is ascertained by a suitable and autonomous method able to be communicated to the small box (1), the transition then being accompanied by the small box's loss of memory of its previous mode. The present invention is particularly for use in the protection of documents or valuables, especially bank notes, cheques, bank cards, or even dangerous medicines (drugs) or those with a considerable added value. Protection is guaranteed both inside a bank (or chemist's, etc.) and during the transportation from the bank to another branch.

Title: Packing construction for pneumatic and hydraulic control apparatuses
Inventor: FRISCH HERBERT
IPC: F16J15/32
Filed: 1982-03-17
Abstract: A sealing device for pneumatic and hydraulic control instruments consists of a sealing ring (3), which seals a closing member (2) displaceably mounted in a housing (1). Two stops (4, 5) are provided for the sealing ring (3), one (4) of which stops is disposed on the housing (1) and the other (5) on the closing member (2). When the sealing ring (3), which can be arranged between brace rings (6, 7), is acted upon on one side by a pressure medium at (9), it is supported by the stop (5) and moves with the member (2), the ring (3) sealing against the housing (1) at its outer circumference. When the stop (4) prevents further movement of the ring (3), the latter seals against the member (2) at its inner circumference. The pressure-loaded surface can therefore be altered without using other components. The device can be incorporated in a control valve (Fig. 6, not shown) where a valve member (26) is maintained seated whether pressure medium is admitted at (27) or at (23). <IMAGE>

Abstract: The invention relates to an apparatus for the automatic and electrical stunning of slaughter animals. It consists of a conveyor apparatus having two sequential groups of two endless belts 1, 2; 1', 2' which run synchronously and in the same direction and which form a conveying channel between their adjacent strands, the working surfaces of these belts being directed downwards toward one another and the two groups each lying in the same plane. At the exit of the conveying apparatus are situated electrodes 5, 6 which can be engaged with the head section of an animal to be stunned. The first group of endless belts 1', 2' has a base which descends downwards in the conveying direction. The speeds of the two groups of belts are different in such a manner that the speed of the second group 1, 2, in the conveying direction, is greater than that of the first group. <IMAGE>

Granted: 1989-12-27
Abstract: To reduce the discharge of dust from a cooling hopper for hot bulk materials, in particular for glowing coke, an asymmetrical annular gas collection space 1 between a pilot chamber 3 and the actual cooling chamber 6 is proposed and is designed in such a manner that the radial velocity of the emerging cooling gas which is discharged through the offtake 2 above the cone of bulk material 10 which has been tipped in to the cooling chamber 6 is kept constant over the periphery of the gas collection space 1. To reduce the quantity of cooling gas required, there is a cooling shield 15 which is thermally connected to the recooling heat take-off 17. In the region of the gas collection space 1, the cooling hopper is secured to an annular carrier 9, on which the pilot chamber 3 is supported, while the cooling chamber 6 hangs from it. This measure minimizes the thermal expansion, in particular in the region of the offtake 2. <IMAGE>

Abstract: An improved assay to determine sensitivity to activated protein C in assay samples has been developed in order to ensure rapid and accurate analyses. This assay is based on measurement of the conversion of added factor X into an activated form by activated factor VIII within an assay sample. The sensitivity of the assay sample to activated protein C is determined from the relative inhibition of the factor X conversion by comparison with a control. An assay sample with reduced sensitivity to activated protein C shows a relatively low inhibition and vice versa.
