Title: Pad including adhesively adhered sheets
Inventor: GRAVLEY LANE
IPC: B42D15/04
Filed: 1998-06-04
Abstract: A pad of paper sheets is constructed so that individual sheets may be removed from the pad without the individual sheets having any aggressively tacky or repositionably tacky coatings on exposed surfaces of the sheets after removal.  There is no need for padding compounds or coatings on exterior edges or sides of the pads. A process for forming such a pad of sheets which can be separated into individual sheets having no aggressively or repositionably tacky surfaces comprising the steps of: (a) applying a coating of adhesive to a surface of a first sheet of paper, causing a first bond strength between said adhesive and said surface, and leaving an unbonded surface of adhesive exposed away from said paper, (b) for a measurable period of time allowing said adhesive to alter its physical properties so that its tackiness on its unbonded surface decreases, (c) contacting a second sheet of paper to said unbonded surface to bond said unbonded surface to said second sheet of paper, the bond between said second sheet of paper and the adhesive having a bond strength which is at least 10 % lower than the bond strength between said adhesive and said first sheet of paper, (d) repeating steps (a), (b) and (c) on said second sheet of paper to create a stack of sheets which are individually separable from each other.

Title: Bearing element for upholstery support for a seat or bed system
Inventor: FROMME HEINRICH
IPC: F16F3/08
Filed: 1998-07-17
Abstract: The invention relates to a bearing element having a base plate fitted on a support, for a seat or bed system, with a bearing plate to hold upholstery. The invention seeks to produce a bearing element whose range of spring is approximately equal to the total height, and which is easy to produce. To this end, at least two spring elements serving as bearing arms (12, 22) are fitted between the base plate (11, 21) and the bearing plate (15, 25). These spring elements, configured like leaf springs, are directed outwards from the base plate (11, 21). Their outer ends join the bearing plate (15, 25). In another version of the invention, a spring body (35, 35') is fitted between the base and bearing plate. The spring body head (35.2) and foot (35.1), like the bearing plate and base plate, have corresponding locking parts, so that the bearing plate can also be removably placed on the spring body (15, 15') and on the base plate (21). The invention also seeks to provide a bed system that is fitted with the inventive bearing elements, and which is characterized by its versatility. To this effect, fixing means for bearing elements are fitted on the plate or laths, preferably as undercrosses (30) that can be connected by socket connectors, with fixing means for the bearing element (10, 20) in the crossing area. A second version of the invention is intended in particular for lath frames (2) with mountable frame part(s) (3, 5, 7). In this version, at least one row of bearing elements (30') belonging to the outer mountable frame part is fitted with bearing elements (35') having a foot support (31) and a bearing plate (20, 40, 50). The other rows have bearing elements (30), which comprise a foot support (31), spring body (35, 35') and bearing plate (20, 40, 50).

Title: Diagnostic test for alzheimer's disease
Inventor: SMALL DAVID HENRY
IPC: C12N9/16
Filed: 1998-09-24
Abstract: A method for the diagnosis of Alzheimer's disease (AD) in a patient, comprising the steps of: (1) providing a sample of an appropriate body fluid from said patient; (2) detecting the presence of acetylcholinesterase (AChE) with an altered glycosylation pattern in said sample. It has been established that approximately 75-95 % of the AChE in the CSF of AD patients binds to Concanavalin (Con A) or wheat germ agglutinin (WGA) but with different specificity to each. Accordingly, in order to identify the glycosylation pattern of AChE in the sample, the binding to Con A is determined, then the binding to WGA is determined, and a ratio calculated. The ratio is characteristic of the glycosylation pattern. In an alternative embodiment of the invention a monoclonal antibody specific for AChE with an altered glycosylation pattern is used to detect its presence.

Title: Method for variable block scheduling indication by an uplink state flag in a packet data communication system
Inventor: TURNIA DALIBOR
IPC: H04W74/04
Filed: 1999-01-29
Abstract: A packet data communications system uses a USF (Uplink State Flag) transmitted on the downlink and interleaved with downlink data, to schedule traffic on the uplink for one or several mobile users utilizing the same physical channel. The USF indication is made variable and defined in the control signaling at setup of a packet transmission. A USF indicates to a mobile that one or several consecutive radio blocks is reserved for uplink transmission from a specific mobile. The mobile does not have to receive the USF during the remaining period defined by the number of radio blocks scheduled. The solution is especially advantageous in combination with adaptive antennas when all radio blocks on the downlink transmissions do not have to be broadcast to all users on a certain channel.
