Title: Improvements in x-ray microscopes
IPC: H01J35/14
Filed: 1957-09-27
Abstract: 848,982. X-ray tubes. GENERAL ELECTRIC CO. Sept. 27, 1957 [Oct. 1, 1956], No. 30335/57. Class 39(1). An X-ray shadow microscope has an asymmetric electrostatic lens system for focusing the electron beam on to the target which is arranged to cause multiple cross-over of the beam, and whose principal plane is positioned between the lens mid-plane and the target. The microscope of Fig. 1 (not shown), is substantially identical with that shown and described in Specification 780,682, except for the objective or focusing lens assembly shown in more detail in Fig. 2, and which comprises three elements 17, 18, 19. The target window 20 is secured to the last element 19, flush with the inner surface. With the object of reducing the focal length, the lens is designed so that multiple crossing of the optical axis A by the electron rays occurs. This is achieved by suitably controlling the potentials in the centre of the element apertures, and also by the spacing and geometry. The spacing S between elements 18 and 19 must be less than the spacing Zo between elements 17 and 18, and the thickness t and aperture radius R 1  of element 18 are such that S / t/2 > 0À5 and t/2 /R 1  > 1. Equations are also given for deriving the potentials at the centres of the apertures, in terms of the applied voltages and the lens dimensions. The arrangement shown has three cross-over points, and it is stated that a focal length of as low as 1 mm. can be obtained.

Abstract: 396,962. Rubber cushions and mattresses. JOHNSON, J. H., 3723, Dundas Street, West, Toronto, Canada. Oct. 29, 1932, No. 30424. [Class 70.] An inflatable rubber structure for use as, or within, a mattress, cushion or the like, comprises extensible side walls with one or more strips of rubber connecting them and permanently vulcanized to them, so as to permit only a limited separation of the walls and to form a plurality of air compartments. Fig. 1 is an external view, and Fig. 3 a cross section, of a mattress in which the side walls 1, 2 are connected together by longitudinal partitions 5 to form three separate compartments each with a separate inflating nozzle 9. In manufacture the two sheets of rubber 1, 2 forming the side walls are superposed, with the partitions 5 folded longitudinally and placed between them. Sheets of paper 3 are inserted between the folds of the partition 5 and other paper sheets 6 are placed between the side walls 1, 2 and the outer side of the folds, leaving the partition 5 in contact with the walls 1 along narrow strips 8. The sheets of paper 3, 6 may be perforated to permit the walls to contact with each other around a series of holes 4 which are designed to permit the threading of tufting cords. When heat and pressure are applied, the partitions 5 are united with the walls 1, 2 along the strips 8, and the walls are united with each other around the holes 4. When the structure is inflated, the partitions 5 first straighten out and then restrain further separation of the walls 1, 2. The structure may be enclosed in fabric and inserted between felted or upholstered layers, Figs. 4 and 5 (not shown), the tufting cords of which pass through the holes 4. In a modification, Fig. 6 (not shown), four partition strips form an inner oblong compartment surrounded by an outer compartment, the strips being arranged so that when the structure is inflated they close together at the corners and permit only a slow displacement of air from one compartment to the other.

A barrel finishing media comprises preformed and sintered bodies consisting essentially of bauxite and finely divided fused alumina particles. The fused alumina comprises from 10 to 80% by weight of said bodies and the media is made by forming a mixture containing comminuted bauxite having an average particle size of 5 microns and finely divided fused alumina together with a small amount, e.g. between 2 and 8% of a suitable organic temporary binder such as for example starch, cellulose derivatives, waxes or an inorganic temporary binder such as bentonite, then adding water to the dry mixture to provide a plastic workable mass after which the plastic mass is formed into bodies by for example pressing moulding, slip casting or extruding; if extruded the extruded rod is cut into bodies of a suitable length by wires or blades and if a temporary binder is used the bodies are first heated in an oxidizing atmosphere at a temperature sufficient to burn out the temporary binder, the temperature not exceeding 1100‹ C. and preferably being between 750‹ and 1000‹ C. If an inorganic binder is used the oxidizing step is eliminated. The shaped bodies are then heated to a higher temperature in the range 1400‹ to 1750‹ C. to sinter them in a neutral, reducing or oxidizing atmosphere; the bodies are then allowed to cool and if desired they are tumbled with water for from 15 to 30 minutes in a rotating barrel to remove minor edge faults.
