Title: Chrystalline members
IPC: C30B27/00
Filed: 1964-09-24
Abstract: Thin platelet crystals having one or more twin planes and (111)-parallel faces are grown from solution by the re-entrant edge crystallization mechanism.  Twinned crystal nuclei without re-entrant edges may first be formed by super-cooling the solution below the re-entrant edge crystallization temperature.  Hexagonal or othorhombic crystals have a minimum of one twin plane.  Face centred cubic, diamond cubic, and zinc blend crystals have a minimum of two twin planes.  The material crystallized may be aluminium, gallium, indium, thallium, silicon, or germanium; or a phosphide, arsenide, or antimonide of aluminium, gallium, indium, zinc, or thallium.  The solvent may be aluminium, gallium, antimony, indium, tin, silver, gold, zinc, mercury, bismuth, or lead.  The solution may be cooled at a rate of up to 3 DEG C. Alternate n-and p-doped layers may be produced.  An elongated crystal may be grown into a solution having a suitable temperature gradient (Figs. 8 and 11, not shown); or may be pulled from a solution whose concentration is maintained constant (Fig. 9, not shown).  In the latter case, solution depleted solvent is caused to overflow from the pulling crucible as pulling proceeds by decreasing the volume of the crucible.

Abstract: 995,091. Preventing overload of cranes. LICENTIA PATENT - VERWALTUNGS G.m.b.H. Nov. 2, 1961, No. 39280/61. Heading B8B. An overload prevention device for cranes comprises circuit elements producing electric signals which individually represent pay-load weight, tare weight and lever arm length, and a signal combining element producing a resulting signal which operates an alarm when a predetermined signal strength is reached. A signal proportional to load weight is fed to an amplifier 4 through terminals 8, 9 and the amplifier output is fed to an adding circuit 5. Here a signal proportional to the weight of the displaceable load supporting structure from a circuit 3 is combined with the first signal. In a multiplying circuit 2 the signal from circuit 5 is combined with a signal representing lever length from an amplifier 1. A potentiometer R 1  responds to luffing movements and a potentiometer R 2  compensates for movements of the crane base from a horizontal plane, e.g. in floating cranes. A first warning signal may be operated when 80% of safe load is reached.

Abstract: 848,772. Hopper discharge. KING. R. P. Dec. 12, 1958 [June 23, 1958], No. 40112/58. Class 78(1). [Also in Group XXIX] Alkali cellulose is discharged from hopper 1 by sets of rollers 3, 4 positioned at the bottom thereof. The sets rotate in different directions. Set 4 is rotated step-by-step by pawl-and-ratchet means which take the form of bar 14, the piston 13 of which is caused to reciprocate by fluid cylinder 12, the bar carrying pawls 15 which operate respective ratchets 16 secured to the respective rollers. Similarly set 3 is rotated step-by-step by pawl-and-ratchet means operated by bar 9 which is caused to reciprocate by piston 8 working in fluid cylinder 7. Bar 14, in its movement, operates valve 23 which by directing fluid from source 17 (via pipe 18) through pipe 22 or 35 operates valve 21 to control the flow of fluid from said source to either side of cylinder 7. Cylinder 7 then operates the piston 8 to move bar 9. Thus the movement of bar 14 initiates the movement of bar 9, and vice versa, to give a rotation of rollers 3 followed by a rotation of rollers 4, and so on.
