Title: Prodn. of syrups contg. glucose and fructose - by contacting poly:fructoside(s) with microorganisms
Inventor: GUIRAUD JOSEPH PIERRE
IPC: C13K11/00
Filed: 1980-06-25
Abstract: Prodn. of syrups contg. glucose and fructose is carried out by contacting polyfructosides with microorganisms in an aq. medium. The process is esp. useful for producing fructose-rich syrups from plant extracts, e.g. extracts of Jerusalem artichokes, dahlia tubers or chicory roots. The microorganism is pref. a non-fermenting yeast contg. a beta-fructosidase, e.g. Pichia polymorpha, Debaryomyces cantarelli or D.phafii (CBS 186, 4349 and 4346 respectively). The process is pref. carried out by (a) contacting the comminuted plant material with water in a battery of diffusers; (b) treating the juice with lime and CO2; (c) adjusting the pH to 3-5; (d) percolating the juice at 20-40 deg.C through a hydrolysis reactor contg. the microorganisms immobilised on a support (esp. wood chips and/or PVC turnings); (e) demineralising the hydrolysate with cation- and anion-exchange resins; (f) concentrating the hydrolysate to 700 g/l; and (g) decolourising the concentrate with animal charcoal.

Title: Bone saw has pivotally mounted support plate - biased by spring into position where saw remains concealed below plate
IPC: B27B5/22
Filed: 1981-05-05
Abstract: A bone saw comprises a (circular) saw blade engaging in a slit in the support plate. This support plate (6) is mounted pivotal about a horizontal axis (5) and is biased upward by a spring (7) so that, in the normal at-rest position, the top of the plate lies above the tips of the teeth of the saw blade (3), thus eliminating risk of injury when placing the bone on the plate. In a preferred arrangement (as shown) a holding down plate (11) is pivotally mounted (12) above the working table and has serrations (16) parallel to its axis to hold the bond in position; by pressing down on this holdinq-down plate, the bone is pressed onto the edge of the saw and the support table (6) is depressed.

Title: Anti:polio-virus mono:clonal antibodies for identification of virus ty - comprises antibodies of 3 serological sub-types, divided into 3 categories dependent on activity against natural, attenuated or both strains
Inventor: BOUE ANDRE
IPC: C07K16/10
Filed: 1981-08-24
Abstract: Monoclonal antibody collection for the diagnosis and identification of poliovirus contains three groups of poliovirus antibodies, related respectively to the serological sub-types (1), (2) or (3). The monoclonal antibodies of each group may be divided into (a) a first category of active antibodies, but which do not show intratypic differentiation; (b) a second category of antibodies active against the attenuated strains, but essentially devoid of activity against the corresponding natural strains and (c) a third category of antibodies active against the natural strain of the serological sub-type being considered, but essentially devoid of activity w.r.t. the corresponding attenuated strains. The antibodies of the first and second categories of each of the above three groups respectively are active against LSc 2ab strain (sero-group 1), P 712 CH 2ab strain (group 2), and Leon 12alb strain (group 3). The antibodies of first and third categories in each of the above three groups respectively are active against Mahoney strain (Group 1), MEF 1 strain (Group 2) and Saukett strain (Group 3). Diagnosis and identification of newly isolated unknown strains of poliovirus as being natural or attenuated types. In the first stage of seroneutralisation tests with sensitive cell cultures in the presence of the three-monoclonal antibodies of the first category of the three groups, the virus is presumed to belong to the first, second or third type according to whether it is inhibited by the antibodies of the first, second or third group. In the second stage, the seroneutralisation tests are repeated under similar conditions but using antibodies of the second category or the third category of the group corresponding to the serotype shown in the first stage tests; the virus being determined as attenuated or natural depending on whether it inhibits the antibodies of the second or third category.

Title: Absorbent or diffusing complex, e.g. for removing perspiration - or delivering drugs, comprising two bonded fibre layers
Inventor: CLAVAUD CHRISTIAN
IPC: B32B7/02
Filed: 1982-01-06
Abstract: Prodn. of absorbent complex and/or diffuser comprises placing a diffuser material (A), made of bonded short natural fibres and synthetic fibres, over a second material (B), which is more absorbant then (A) and functions as a reservoir.

IPC: F16F9/36
Filed: 1982-01-11
Abstract: In a hydropneumatic twin-tube oscillation damper, the inner cylinder (3), which is filled with damping fluid, is divided by the working piston (2), contained in it and provided with damping valves acting in the tension and in the compression stage, into an upper and a lower working chamber (6 and 7 respectively), the lower one (7) of which is connected via a bottom valve (8) provided with throughflow openings to that region (5) of the outer cylinder (4) which contains the damping fluid, while the upper working chamber (6) is connected via a bleeding device provided with a non-return valve (23) to the upper pressurised gas-containing region (5') of the outer cylinder (4). In order to achieve even more effective bleeding and to be able to operate the damper with an even lower gas pressure charge without foaming, all the compression-stage throughflow openings (34) in the bottom valve (8) are covered so stiffly by a valve spring disc (35) that the pressure build-up which can be achieved by them is larger than the pressure reduction which arises at the compression-stage valve of the working piston.
