Title: A method of securing first and second components against relative displacement and an assembly of first and second components produced thereby
IPC: F16B1/00
Filed: 1980-12-19
Abstract: First and second components, such as a housing 10 and a cover 11 of a gear machine, are secured against relative displacement by providing a bore 14 in the first component, fitting a centering member 13 in the bore, effecting mutual engagement of the components in a desired relative position, for example by bolting or screwing them together, and forcing the centering member into the second component. If desired, two such centering members may be used. The components need not be accurately aligned before securing them against relative displacement and only a single bore need be formed in one of the components thus providing an extremely cheap assembly. The centering member 13, a shouldered pointed pin, a ball, a blunt pin, or a sleeve with a cutting edge which is forced through the bore in the first component into a bore in the second component, which need not be accurately aligned with the first bore, whereupon the cutting edge removes material from the wall of the second bore. <IMAGE>

Title: Improvements in or relating to printing plates
IPC: G03F5/12
Filed: 1981-05-26
Abstract: Lithographic printing plates capable of providing improved tonal reproduction and tonal range are obtained by exposing radiation sensitive material to actinic radiation which has not only been modified by being passed through a continuous tone original but also by being passed through a tone control filter which is such as to transmit radiation in the form of a pattern which has areas of relatively high, low and intermediate intensities so as to exhibit a tonal range. The tone control filter may include areas of differing opacities to actinic radiation in which case the tone control filter has an integrated density of at least 0.2. Alternatively, the tone control filter may be in the form of a lenticular screen arranged to modify radiation passing therethrough so that it has the desired pattern. The filter having differing opacities is prepared by uniformly exposing and developing a coarse grained silver halide material, which is then used to expose a diazotype material which is developed to give the filter.

Title: Blood Clotting Factor Production
IPC: A61K38/00
Filed: 1981-07-01
Abstract: The 3-4% PEG precipitate of cryoprecipitate which is normally discarded during the process of obtaining high purity Factor VIII concentrate from human blood has been found to be usable as a starting material for the production of a Von Willebrand clotting factor concentrate which when intravenously administered to a Von Willebrand haemophiliac either as it is (when in liquid form) or else together with a pharmaceutically acceptable carrier in as an effective clotting amount is capable of bringing about blood clotting at the locus of bleeding in a Von Willebrands disease sufferer. A liquid concentrate of this invention may be prepared by solubilising a 3-4% PEG precipitate with a solubiliser which can take up most of the Von Willebrand factor present in the precipitate, preferentially precipitating fibrinogen from the thus obtained solution, treating the fibrinogen free supernatant with an adsorbent which will adsorb clotting factors II, VII, IX and X, subsequently treating the supernatant obtained with a precipitant which is capable of precipitating all of the protein present and then solubilising the thus obtained precipitate with a solubilizer capable of taking up most of the Von Willebrand factor present. The liquid concentrate of Von Willebrand factor obtained may, if desired, be lyophilised.

Title: Emitron: a microwave diode
Inventor: CRAIG GEORGE D
IPC: H01J25/00
Filed: 1983-04-18
Abstract: The invention comprises a new class of device, driven by electron or other charged particle flow, for producing coherent microwaves by utilizing the interaction of electromagnetic waves with electron flow in diodes not requiring an external magnetic field. Anode and cathode surface (14, 16,) are electrically charged with respect to one another, for example by a Marx bank voltage source (30, 58), or by a high energy charged particle beam (80, Fig. 3, not shown) incident through the tube envelope. This produces an electric field which stimulates an emitted electron beam to flow in the anode-cathode region. The emitted electrons are accelerated by the electric field and coherent microwaves are produced by the three dimensional spatial and temporal interaction of the accelerated electrons with geometrically allowed microwave modes which results in the bunching of the electrons and the pumping of at least one dominant microwave mode. <IMAGE>
