In the embodiment shown, the drum is frusto-conical and is supported on a base-plate 19 whose inclination is adjustable by means of a spindle 24. In other embodiments the impermeable part 11 of the drum is cylindrical and the perforate part is either cylindrical or frusto-conical and of smaller diameter than the impermeable part, Figs. 3 and 4 (not shown). Alternatively both parts 11 and 12 may be cylindrical and of the same diameter, the drum being rotated about an axis which is inclined to the horizontal. The interior surface of the drum may be provided with longitudinally extending ribs. In use the hot sand moulds and castings are fed into the rotating drum via a vibratory shoot 6 and are conveyed towards the outlet 8. The moulds are broken up and the sand discharged through the holes in the perforate portion 12 on to a conveyer 14 while the castings pass through the outlet 8 and on to a conveyer 10. Air is drawn through the drum by steam extraction means connected to the inlet 5 and water may be sprayed into the drum. The residence time of the material in the drum and the extent to which it is cooled may be adjusted by changing the inclination of the drum to the horizontal and by changing the speed of rotation of the drum.

Abstract: 997,228. Semi-conductor rectifiers. STANDARD TELEPHONES & CABLES Ltd. Dec. 21, 1961 [Dec. 22, 1960], No. 45852/61. Heading H1K. By forming a high doped semi-conductor body 1 and an electrode 4 with a coating 6 containing an impurity of opposite conductivity type to the body so that they have an area of contact small relative to the maximum cross-section of the body 1, and heating the assembly to melt the coating 6, a small PN junction is formed at the same time as the body 1 is attached to the electrode 4. By this means the capacitance of the junction and the series resistance provided by the body 1 are kept small and conditions necessary for a tunnel diode are fulfilled. At the same time as electrode 4 is attached a second electrode 5 may be attached, a coating 7 of the same conductivity type as the body 1 being used to effect an ohmic contact with the body. The electrodes 4 and 5 are of silver or copper, the coating 6 is an alloy of 95% tin and 5% arsenic, the coating 7 is of tin, and the body 1 is of P-type heavily doped germanium. Insulating spacing means may be placed between the electrodes and a ceramic annulus with metallized ends is preferably employed so that it bonds with the layers 6 and 7 during the heating process and provides a sealed housing. Alternatively the space between the electrodes and surrounding the pellet may be filled with a cold-setting resin. The semi-conductor body 1 is preferably a sphere of 20 to 30 microns in diameter produced by dipping or spraying the molten material or by heating the powdered material which contracts into globules on melting. The body 1 may also be conical with its small truncated end used to form the junction and the base the ohmic connection. Conically-shaped bodies may be produced by cyclically varying the rate at which a crystal is withdrawn from a melt, individual cones being sawn off the resulting crystal.

Abstract: 1,201,946. Resonant cavities. NORTH AMERICAN ROCKWELL CORP. 11 Oct., 1967 [20 Feb., 1967], No. 46442/67. Heading H1W. [Also in Division H3] The boundaries of a waveguide cavityresonator are provided by grooves in the waveguide wall having a depth of one quarterwavelength #/4 at the resonant frequency. In the " exploded " diagram of Fig. 1, a rectangular waveguide 20 of dimensions a, b is formed by the juxtaposition of three elements 10a, 10b, 10c, a fourth element 10d providing a termination for the waveguide. Element 10c is formed with longitudinal grooves 32a, 32b, 33a, 33b which determine the width w of a cavity 35. The length l of the cavity 35 is equal to the length of element 10c and is delimited by grooves 31a, 31b. The latter 4rooves are formed by the interposition of the thin element 10b having an aperture 31 cut as shown, with d = #/4. The cavity may house a diode 12 forming the active element of a parametric amplifier. Aperture 40 in element 10d forms a waveguide which is beyond cut-off for waves propagated in waveguide 20. The grooves have a width t ##/10 at the resonant frequency of the cavity and offer a small inductive reactance to waves of a low signal frequency propagating in waveguide 20. They offer sufficient impedance through guide 40, to confine these waves to the cavity and the cavity is dimensioned to resonate in the TE 303  at this frequency. The varactor diode 12 is positioned at a point of maximum electric field intensity. Modifications are described in which double grooves are used and in which two cavities operating at different frequencies are arranged in tandem in the waveguide.
