Abstract: 1,183,028. Hydraulic turbines. VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE A.G. Nov.4, 1968 [Nov.22, 1967], No.52103/68. Heading F1T. A hydraulic turbomachine which can be selectively operated as a turbine or as a pump has axially spaced guide vane rings 7, 8 for pump or turbine operation, respectively, and a rotor consisting of an annular bladed member 10 and an inner bladed member 12, the latter being axially movable from a position in which its blades 13 act as turbine blades to a position in which its blades co-operate with the blades 11 of member 10 to act as pump blades. Member 10 is fixed to the rotor shaft 9 and inner member 12 is fixed to an auxiliary shaft 14 mounted within shaft 9 for rotation therewith and axial movement relative thereto. The latter movement is effected by controlling the supply of oil to either side of a piston 16 slidable in a chamber 15 of shaft 9. In the right half of Fig. 2 the inner member 12 is shown in its lower position in alignment with guide vane ring 8 for turbine operation. A set of adjustable guide vanes 8a is also provided. The annular member 10 also has a lower set of rotor blades 19 in alignment with vanes 8, 8a for turbine operation. When pump operation is required, inner member 12 is moved to its upper position, shown in the left half of Fig. 2, in which its blades 13 co-operate with the blades 11 of member 10 to discharge past guide vane ring 7. The pump and turbine volutes 2, 3 are separated by a wall 1 having an inner hollow extension 21 forming a shroud for the guide vanes 8a and part of the rotor blades 11. The cavity within extension 21 may be used for draining the rotor area. The volutes 2, 3 communicate with separate pipes (4, 5, Fig. 3 not shown), each having a shut-off valve (6). Inner member 12 carries a cylindrical member 18 so that it connects with suction pipe 17 in both its upper and lower positions. In a modification, Fig. 1 (not shown), lower rotor blades 19 are eliminated. Member 10 may have a larger number of blades than inner member 12.

Abstract: 1362678 Automatic electric control of movement VARIAN ASSOCIATES 12 Nov 1971 [27 Nov 1970 (3)] 52585/71 Heading G3N [Also in Divisions G4-6 and H5] In a computer controlled radiation therapy machine the radiation head support and patients table are moved simultaneously to new positions by control signals derived from a comparison of their actual positions, as derived from position sensors, and their new positions. A magnetic tape cassette unit 28 contains in digital form the radiation treatment for a particular patient which comprises a sequence of steps, each step defining an angular position of the radiation head (12) support structure 8, the X, Y and Z positions of the table 2 plus its angular position about vertical axis 4, and information regarding the radiation dose to be given. Analogue position sensors provide the computer with position signals of the table and support structure in the above mentioned directions and orientations which are converted to digital form and compared with new position signals from the tape. An operator commands from a CRT/keyboard terminal 29 the initiation of each step and the computer in multiplex fashion derives digital position error signals which are converted to analogue form to control D. C. motors driving the elements in the above mentioned direction and orientation. The computer is programmed to determine from the actual position signals when any part of the table and support structure are on a collision course and causes the element to retreat to a zero position to begin again. Upon failure to reach the positions after a predetermined number of attempts a warning is given to the operator. Radiation doses are displayed to the operator who controls the setting of the radiation source to give that dosage. The operator may edit the data on the magnetic tape by means of his keyboard with the computer checking the input data to determine whether it is within the permissible limits.

Abstract: 1315230 Memory IGFETS NATIONAL CASH REGISTER CO 16 Nov 1971 [3 Dec 1970] 53084/71 Heading H1K In a memory IGFET in which the channel is defined between source and drain regions formed in the surface of a body of opposite conductivity type and the gate insulation comprises two superposed layers of different insulating materials exhibiting charge storage at their interface the lower layer has a portion adjacent the drain and optionally adjacent the source region which is so much thicker that no charge occurs above it. The lower layer which should have low charge-trapping capability is of alumina or preferably silica and is about 30  thick except adjacent the drain (and source) where its thickness is 400 . The upper layer having a high charge-trapping capacity is silicon nitride 750  thick and carries an aluminium gate electrode. Non-uniformity of the oxide is produced by etching through part of a grown layer and reforming the oxide there to a lesser thickness. The effect of the thicker oxide at the drain is to raise the drain-substrate breakdown voltage and to provide a negative value for the threshold voltage (when the substrate is N type) irrespective of the condition of the memory, which is a stored charge produced by a high-voltage gate pulse of at least 1 ms. duration.
