Title: Control system for hydrocarbon hydroconversion processes - to monitor process parameters and regulate hydrogen hydrocarbon mole ratio
IPC: C10G49/26
Filed: 1976-07-28
Abstract: A technique for controlling the hydrogen/hydrocarbon mole ratio in continuous, catalytic, hydrogen-consuming or hydrogen-producing hydrocarbon conversion processes involves employing analysers to monitor composition characteristics of the charge stock and of the liquid reaction effluent and the hydrogen concentration of the vaporous phase introduced into the reaction zone, and transmitting representative output signals to comparator/computer means which generate additional comparator output signals which are utilised in the control system for regulating the H2/hydrocarbon ratio. The technique is applicable to processes in which the reaction zone effluent is separated into liquid and H2-rich vapour phases, a portion of the latter being recycled to the reaction zone.

The workpiece is clamped in the position as determined by the stop and the frame is pivoted into a horizontal position.
Patent NL-8503520-A (NL)
IPC: B26B19/14
Filed: 1985-12-20
Abstract: A dry-shaving apparatus comprises a housing having a holder for a shear plate with hair-entry apertures and a cutter which is rotatable about an axis of rotation and which comprises a carrier for cutting elements which are movable relative to the carrier, in which during rotation of the cutter, as part of a revolution, each point of a cutting edge at the end of a cutting element follows a constrained path which is defined by the shear plate and each point of a cutting edge follows a circular free path when the ends are clear of the shear plate. At the more advanced axial end of the first cutting element, viewed in the direction of rotation, the radius of a circular free path of the cutting edge is smaller than the distance from the axis of rotation of the corresponding portion of the shear plate at the location where at this end the free path changes into the constrained path, so that the cutter comes gradually into contact with the shear plate.

Title: Anti-idiotype antibodies that are reactive with shared idiotopes expressed by human lymphomas and auto- antibodies
Inventor: MILLER RICHARD ALAN
IPC: C12P21/08
Filed: 1990-02-14
Abstract: B-cell lymphomas express on their surface an immunoglobulin containing unique idiotypic determinants (idiotype) which can be used as specific tumour markers. The applicant produced monoclonal murine antibodies (MAbs) reactive with the idiotype marker derived from 67 patients with a low level of follicular, small cleaved cell lymphoma. Of 199 monoclonal antibodies, 47 (24%) reacted with a mixture of normal human serum immunoglobulin at concentrations ranging between 0.6 μg/ml and 160 μg/ml.  Of these 40 monoclonal antibodies, 90% give a cross reaction with idiotype present in normal serum at levels < 50 μg/ml.  Thirty- two of these anti-idiotypes were directed against a shared idiotope expressed in other cells from a patient with lymphoma.  The frequency of expression of the shared idiotope defined by each antibody varied between 0.26% and 3.9% of the B-cell lymphomas tested.  A panel of five anti-idiotype antibodies reacted with 80% of the lymphomas associated with AIDS. Based on the reactivity with these monoclonal antibodies, the tumours could be grouped in distinct families.  In aggregate, these 32 monoclonal antibodies reacted with a total of 108 of 332 cases of B-cell lymphomas (32.5%), including 35 of 1/6 follicular, small cleaved cell lymphomas (30%).  Many of these shared anti-idiotopes reacted with more than one histopathological subtype of lymphoma. The anti- idiotypes have been used in the diagnosis and treatment of B-cell lymphomas.  Furthermore, the applicant discovered at least seven anti-shared idiotype antibodies which give a cross reaction with auto-antibodies, e.g. 16.6 and RF.  The development of a library of anti- idiotypes that are reactive with shared idiotopes will make it possible for these clinical studies to obviate the need to develop a specific hybridoma for each patient.
Patent PT-93305-A (PT)
Inventor: THANISCH KLAUS
IPC: E05D1/02
Filed: 1990-03-01
Abstract: A one-piece plastic closure comprises a lower part (1), a lid (3) and a snap hinge (6). In order to connect the lower part directly to the lid (3), the snap hinge comprises one or more film hinges (8) aligned in the main axis of rotation (10). The snap hinge comprises at least one elastic element (14) which, in the closed position, does not project beyond the external profile of the adjacent sections of the lower part and of the lid, but is as flush as possible with them. The elastic element is connected to the lid and the lower part by linear articulations (16) parallel to the main axis of rotation, at a certain distance from the latter. At least one film hinge is located with the necessary play on the outer faces of the lower part and of the lid. The sections of the lower part and of the lid immediately adjacent to the film hinge have marginal surfaces (22, 24) inclined to their outer face (bevelled edges) which in the closed position are adjacent and in the open position swivel apart. In the closed position of such a closure, the film hinges do not project outward. Instead, they are located in the outer wall of the lower part and in one edge or outer wall of the lid. The lid and the lower part can also be connected by a small strip (30) or several aligned small strips. In this case, the small strip is fully retracted inside the outer profile when the closure is closed.

Title: Method for producing nonslip floor coverings
Inventor: SIEVERS THOMAS
IPC: B23K26/00
Filed: 1998-04-09
Abstract: The invention relates to a method for producing nonslip floor coverings (1) made from mineral materials such as natural stone, fine stoneware, artificial stone or ceramics. The inventive method is carried out in two stages. In the first stage, micro-craters which are invisible to the human eye are created and statistically distributed on the surface of the floor coverings or slabs by means of pulsed laser bombardment. According to the invention, the surface of the floor coverings or slabs thus obtained are subsequently subjected to hydromechanical post-treatment, wherein the surface of the laser-structured floor covering or slabs are sprayed at least twice with a liquid (3, 8) e.g. inorganic acid or halogen hydrogen acid. The final spray process (8) is used to clean and/or neutralize previous spray liquids from the surface of the floor covering (1) or slabs. After each spray process, at least one further process occurs wherein the spray liquid is distributed homogeneously on the surface of the floor coverings or slabs and excess spray liquid is removed (12) from this surface. Subsequently, at least one drying process (13) is carried out.
