Title: Method of providing fixing means on members formed of refractory  material
IPC: F01D5/28
Filed: 1972-12-12
Abstract: 1432340 Manufacture of fixing members RUSTON GAS TURBINES Ltd 16 Nov 1973 [12 Dec 1972] 57267/72 Heading B3A A method of providing a turbomachine blade member made of refractory material with accurately positioned fixing, locating or connecting means, comprises securing a piece of workable material to the member and subsequently machining the piece to provide the fixing, locating or connecting means. A turbine stator blade segment of high temperature Ni-base alloy is cast with oversize holes for accommodating fixing pins or dowels. A machinable Ni-base alloy is inserted and welded or brazed into the holes in the segment. The blade segment is then mounted in a jig and drilled accurately through the inserts. Alternatively, a workable insert can be mounted in the casting mould and the refractory material cast around it with subsequent drilling of the insert. The blade segments can then be assembled in a housing. The refractory material may comprise creep and heat resistant N-base alloys, ceramics and cermets.

Filed: 1970-12-09
Abstract: 1309160 Test probes INTERNATIONAL BUSINESS MACHINES CORP 9 Dec 1970 [22 Dec 1969] 58402/70 Heading H2E An electrical test probe assembly comprises conductive guide tubes 15, fixed at one end in holes through a plane insulating plate 33, probe wires 11, each loosely positioned in a guide tube and extending out of the plate 33 to contact terminals 12 of components 13 to be tested, and conductors 38 for electrical connection to a test apparatus (not shown). The tubes 15 are of highly electrically conductive material (e.g. coin silver) and the wires 11 are of material (e.g, beryllium-copper) with lower electrical conductivity and higher resistance to abrasive wear than the tubes. The tubes are bent through an angle of up to 90 degrees and their ends remote from plate 33 abut and are attached to a pressure plate 34 on an insulating wall 35. Wires 11 act as longitudinal springs so that unevenness of the surface to be contacted is compensated for; also, since the tubes 15 are curved, contact between the wire and the tube is close to the extended tip of the wire. Plate 33 is formed from a thin plate of, for example, acrylic plastics stock. Guide tubes 15 pass through holes in and are soldered to conductors 38 on the sides of terminal board 39. Between the plate 33 and board 39 the tubes are fanned out. To manufacture the assembly the parts shown in broken lines in Fig. 2 are positioned in a mould which is then filled with encapsulating material, e.g. epoxy resin, which is then cured. Fig. 5 (not shown) depicts the assembly adjacent to a wafer on the stage (76) of a test stand. Observation of the contacts is made through a window in the housing by means of a microscope (53) and illumination is provided by a lamp (67).

Title: Process for Preparing Maltose- Containing Starch Hydrolyzate and Crystallization of Maltose therefrom
IPC: C13K7/00
Filed: 1979-01-11
Abstract: Crystalline maltose in good yields is obtained by subjecting a starch hydrolyzate having a maltose content of at least 75% and a viscosity of greater than 400 cps. to the action of glucoamylase, whereby the viscosity is reduced to below 400 cps. without any substantial reduction in the maltose content, and then subjecting the resulting hydrolyzate to a conventional crystallization operation. Crystallization is brought about by bringing the enzyme treated hydrolyzate to a state of supersaturation with respect to maltose by increasing the temperature and solids content, and inducing the start of crystallization in the super- saturated solution. The temperature is then lowered until at least 25% of the maltose has crystallized. Maltose crystals of a size of at least 120 microns x 50 microns are recovered from the massecuite.
