Abstract: 557,191. Screw propellers. CONSTANT SPEED AIRSCREWS, Ltd., McGLASSON, R., and MARSHALL, F. G. June 4, 1942, No. 7589. [Class 114] De-icing liquid is conveyed centrifugally to pipes 22, located within the hollow propellor blades 3 and extending along the leading edge of each blade, from a tank 8 rotating with the hub of the propeller. In the form shown the liquid proceeds from the tank 8 through a selected one of a number of different-sized passages in a valve 12 to a trough 20 flexibly connected to the tube 22. The particular passage is selected by rotating the valve by ratchet and pawl mechanism, the pawl 18 being carried by the blade root so as to be operated when the pitch of the blade is slightly varied. Alternatively the valve may be operated thermostatically. Specifications 523,332, 540,013, 548,272 and 556,494 are referred to.

Class 146(1) A holder for a pile of loose sheets 1 of paper or the like, each having at least two holes 7 to one side communicating through a narrow throat 16 within the adjacent edge 17, comprises a rigid backing member 4 having a cross-section in the shape of three sides of a rectangle and two covers 32, 33 attached to the backing, member at least one of the covers , being able to open bookwise, the two sides 2, 3 of the backing member being joined by at least two posts 6 which pass through the holes 7 and are rotatable about their centre lines, each post 6 being oblong in cross-section to be engaged by papers with the shorter side of the oblong short enough, but the longer side too long, to pass through the throat 16 so that in one angular position of the posts the sheets 1 are held in position but when the posts are turned through 90 degrees sheets can be inserted or removed from the pile at any desired position. Each post 6 has circular ends 8 and carries a circular flange 9 at each end which abut the sides 2, 3, the ends 8 projecting through holes in the sides 2, 3 to receive spring clips 10 'in grooves 11. To rotate the posts 6, each upper flange 9 carries an upstanding pin 12 which passes through an arcuate slot 13 in the side 3 and each upper end carries a projecting pin 14, either pin be-. ing usable to turn the post through about 90 degrees. The pins 14 may be interconnected by a rod so that both posts may be turned thereby. The posts 6 have parallel grooves 15 and only the width across such grooves is less than the width of the throats 16 so that adjacent sheets are not removed by friction accidentally. A plate 18 locks the sheets 1 against the side 2, the plate having keyhole slots 19 with a non-circular slot 21 to engage the grooves 15 and a circular part 20 in which the posts 16 may be turned. A knob 22 is provided for moving the plate 18 to which access is obtained through a hole 23 in the top cover. The length of the posts 6 may be adjustable by having the circular part 8 separate and screwing into a recess in the oblong part 6.

Abstract: 1,155,496. Memory matrix circuits. RADIO CORPORATION OF AMERICA. 20 Feb., 1968 [6 March, 1967], No. 8198/68. Heading H3B. A plurality of arrays a, b, c, d in a memory are arranged in pairs the arrays of each pair being energized by common bit drivers D 1 , D 2  and/or common switches S 1 , S 2  for reading and writing. In Fig. 1 only drivers D are common to the arrays of a pair. Magnetic cores M in arrays a and b of a pair are differently orientated with respect to the row and column conductors so that a read current in one array flows in the same direction as a write current in the other. For reading, one of the current switches D 11 , D 12  and one of the voltage switches S 11 , S 12  are closed to energize a bit conductor in array a, while one of the switches D 21 , D 22  and one of the switches S 23 , S 24  are closed to energize a corresponding conductor in array b. The reading operation is followed by a writing operation in which the switches are selectively closed to energize the same row conductors as were energized previously, but with the current flow reversed. An appropriate column conductor 10 is energized simultaneously with the row conductors during the reading and writing operations. Intsead of using two sets of current switches D and four sets of voltage switches S, it is possible to have four of the former and two of the latter, or three of each. Thus in Fig. 4 (not shown) the arrays ot the pair have common switches S, while in Fig. 5 (not shown) they have common drivers D for reading from one array and writing in the other, and common switches S for writing in the first array and reading from the other. The current switches may be transistors.

[Also in Division H3] In a method of manufacturing a printed circuit board the conductive material forming the printed circuit elements is held in contact with a temporary sheet by suction whilst a support member is attached to the conductive material by adhesive. A sheet of glass 1 is provided with a laminate of copper 2A, 2C and polytetrafluorethylene 2B and the edges of the laminate are sealed to the surface of the sheet 1 by plastic tape 3 along three edges. A pumping shoe connected to a vacuum pump, Fig. 1 (not shown), is placed over the fourth edge and the air in the space between laminate 2 and sheet 1 is exhausted to maintain the laminate and sheet in close proximity. After etching the desired circuit pattern in copper layer 2A a resin bonded fibre board 10 is affixed by resin 9 to the upper surface of the laminate 2 and pressure is applied to form a continuous pool of resin round the edges of board 10. A further layer 11 of resin is placed on top of the board and a sheet 12 of aluminium is placed on the layer and pressure applied thereto.

Abstract: 1,106,470. Producing neutrons. ATOMIC ENERGY OF CANADA Ltd. 22 Feb., 1967 [10 June, 1966], No. 8541/67. Heading G6P. In a neutron generator, a proton beam impinges on a liquid lead-bismuth alloy target. The alloy flows down a vertical tube at a controlled speed such that a free surface, the target, is maintained within the tube. A vacuum is maintained above the surface and the proton beam is incident vertically downwards on the target. A heavy water moderator surrounds the target tube and is provided with experimental neutron beam apertures. The alloy flows through a heat exchanger prior to entry into the tube and the target level is adjusted by nitrogen gas pressure applied to the alloy circuit.
