[Also in Division F4] A horizontal table 2 is vibrated vertically, while being maintained parallel to its original plane by guide means 7, by vibration generating means comprising at least one flexible drive-rod 6 formed of two aligned parts 10, 13 connected together, the part 10 being rigid, with its outer end journalled on an eccentric crank-pin 11 of a drive-shaft 12, and the part 13 being flexible with its outer end embedded in structure 14 connected to the table 2. As shown, two spaced apart rods 6 lie in a plane of symmetry of the table 2. The member 14 of one is guided by parallel flexible blades 25, 26 rigidly secured to the member 14 and to a support beam 24. The member 14 of the other is guided by a flexible rod 27. To allow small adjustments to the slight tilt of the table 2, a rod 17 is clamped between the member 14 and a block 18 welded to the table at 22. In a modification (Fig. 3, not shown), the table is supported and vibrated by four rods 6 set at the corners of a rectangle, the members 14 being secured directly to the table. The vibrating table is used in cooling or drying apparatus as the base for a fluidized bed of particulate solid material (see Division F4).

Abstract: 438,842. Making bent plywood articles. HALILA, Ltd., 330, Bush House, Aldwych, London.-(Roemer, A. ; Malm, and Treistman, S. ; Halila, both in Finland). March 12, 1935, No. 7695. [Class 145 (ii)] Plywood sheets or articles, such as canoes &c. which are curved in more than one plane, are produced by bending a number of wood veneer sheets individually to the desired shape, assembling the bent sheets with interposed adhesive, and pressing the sheets together to effect adhesion. Apparatus for bending the sheets comprises a hollow former 1 which is heated, preferably electrically ; arms 3, 4 of inverted U-shape are pivotally mounted on a shaft 2. Each arm has crossbars 6, 8 in which are guided a number of rods 9, connected at their lower ends by a flexible strip 13 of wood or metal. In operation, a damped veneer sheet is placed on the former 1, and the arms 3, 4 swung outwardly and downwardly whereby the veneer is pressed on to the former by the flexible strips. The rods 9 are urged downwardly by springs 10 or rubber &c. resilient members, hydraulically or pneumatically. The upper cross bar 8 can be moved upwardly in the arm to relieve the pressure on the rods 9 for inserting the veneers. The bent sheets are placed one within the other with interposed adhesive in a hollow mould and subjected to pressure to unite them.

Abstract: 1,169,854. Endless conveyers. BARRYWEHMILLER CO. 16 Feb., 1968 [26 May, 1967], No. 7849/68. Heading B8A. Bottles C are fed into the pockets 20 of a conveyer 19 of a sterilizing machine by an endless conveyer 46 acting in conjunction with pairs of pocketed wheels 31, 34, and a control cam 40. Each of the wheels 34 are formed so that every third pocket is of wider pitch. This is to enable each third fed bottle to move forwards to a greater extent and dodge the oncoming wall 70 of the pocket 20. The cam 40 may have a single flat (as shown) or it may be of double-lobe formation (40a) (Fig. 11, not shown). Each wall 70 is slotted so as to engage longitudinal guides 62. On the upper run of the conveyer 19, the bottles become inverted and rest with their locks located in socket portions 72 of the conveyer 19. After passing around the conveyer and being subject to sterilization treatment (not shown), the bottles are removed by a conveyer 66. This may alternatively be disposed on the other side of the conveyer 19 (Fig. 12, not shown).

The sulphate present should exceed 10 per cent of weight of flux materials; the oxide should not exceed 5 per cent of the phosphor. Amount of sulphate present is controlled by firing in a reducing atmosphere or by controlling air or oxygen present, or by direct reduction with illuminating gas, carbon disulphide, nitrogen, hydrogen or hydrogen sulphide, or by including starch, sugar or other organic compounds in the firing charge. Calcium fluoride is instanced as a fluxing addition. The finished phosphor may include 20 per cent magnesium oxide as a filler after which it is reheated to a low temperature. It may also be mixed with methyl methacrylate and a solvent and sprayed or moulded into flat or curved sheets. Gadolinium and some of the other rare or very rare earths may be added as auxiliary activators. There are figures showing excitation, stimulation and emission spectra of certain phosphors.
