Title: Modulatory proteins of human cns receptors
Inventor: FOLDES ROBERT
IPC: C12P21/08
Filed: 1995-03-27
Abstract: ABSTRACT        Neurotransmission by excitatory amino acids (EAAs) such as glutamate is mediated via membrane-bound surface receptors. This neurotransmission has been found to be modulated by certain modulatory proteins. DNA coding for a family ofsuch modulatory proteins has now been isolated and the modulatory proteins have been characterized. Herein described are recombinant cell lines which produce these modulatory proteins as heterologous membrane-bound products. Also described are related aspects of the invention, which are of commercial significance, including the use of cell lines which express the modulatory proteins either homomerically, orheteromerically in a complex with an NMDA receptor, as a tool for discovery of compounds which affect the function of the modulatory proteins.

Title: Roll screen with variable aperture
Inventor: JOHANSSON JONNY
IPC: B07B1/14
Filed: 1994-07-05
Abstract: The invention relates to a roll screen having variable screening apertures and comprising axle-fitted rolls which are spaced at adjustable distances apart, including means for adjusting this spacing. The roll spacing adjusting means functions to act on all rolls simultaneously, so that the spacing change will be the same for all rolls. The means includes two parallel running tracks (10, 11) and the distance between these tracks can be varied. A change in the distance between the running tracks causes the roll axle housings (6) to rotate and therewith move the axles (2). The roll screen also includes means for adjusting the individual distance between two consecutive rolls without affecting the distances between remaining rolls. This means includes a spacer (32) which is inserted between the housings of the two rolls in which the roll axles are journalled. The roll screen is also provided with a separate elastic sealing element between the roll axle and the roll drive arrangement.

Abstract: Stable, silicate-free, soft metal safe, alkaline cleaners are provided. The cleaners comprise calcium ions and surfactants containing hydroxyl and/or carboxylic acid groups or a combination thereof, wherein the total of the two functionalities in each surfactant is greater than or equal to 2, and alpha-hydroxy carboxylic acids. It has been surprisingly discovered that alpha-hydroxy carboxylic acids such as tartaric acid, are capable of keeping calcium ions in an alkali solution. The cleaners may also comprise non-ionic surfactants to provide wetting, detergency, and foamability where required, anionic surfactants as viscosity enhancers in the case of high retention cleaners, and solvents such as alcohols, glycol ethers, or hydrotropes to enhance solubility of the system. The alkaline cleaners are safe to use on soft metal surfaces and equipment commonly found in many industries, without the presence of silicate which is normally used as a corrosion inhibitor.
