Abstract: 1,011,709. Fluid actuation of switches. CONTROLS COMPANY OF AMERICA. May 24, 1963, No. 20744/63. Heading H2B. In a switch of the type wherein the operating pressure is set by a cam 54 acting on a spring 46 loading the diaphragm 20 and in which the contacts are reset each time the adjustment is changed from one depression 52 to another, means are provided to prevent completion of resetting and operation of the switch if the cam is inadvertently left between settings. Diaphragm 20 acts through a stud 28 on tongue 32 of a snap-action change-over switch 34 and between settings of cam 54 one of the lobes 58 lifts the plunger 48 causing projection 49 thereon to return the stud 28. This would normally reset the switch but a U-shaped member 62 is also lifted by plunger 48 (via spring 66) so that its arms 72 engage the switch blade 34 and hold it in an intermediate condition (Fig. 3, not shown) until the plunger 48 reverts to a position determined by a depression 52. The spring 66 allows for overtravel of plunger 48.

Patent GB-627286-A (GB)
Title: Process for producing rare earth metals
IPC: C22B59/00
Filed: 1945-08-14
Abstract: In a process for producing metals or alloys of metals of the rare earth series, extending in the order of increasing atomic number from lanthanum to lutecium and including yttrium, which are substantially free from impurity other than magnesium, an alloy of the said metal or metals with magnesium is produced and said alloy is submitted to a distillation to separate practically all the magnesium.  The magnesium alloy may be obtained by melting magnesium in the presence of one or more salts of elements of the cerium or yttrium groups to which one or more halides such as alkali metal chlorides have been added.  This process may be modified by increasing the specific gravity of the rare earth metal alloy through previously alloying the magnesium with a heavy metal such as zinc or cadmium, which may subsequently be separated from the rare earth metal or alloy by distillation.  The magnesium may be distilled in vacuum or in the presence of an inert gas such as argon.  Alloys to which reference is made contain respectively 10.7 to 11 per cent or 8 per cent neodymium, 10.5 per cent or 8.6 per cent gadolinium, and 10 per cent cerium, the balance in each case being magnesium.

Title: Improvements in drawing and flattening sheet glass
IPC: C03B15/02
Filed: 1925-08-21
Abstract: 246,057. Tennant, W. J., (Empire Machine Co.). Aug. 21, 1925. Drawing. - In order to flatten sheet glass made by a continuous drawing process, it is drawn vertically upwards from a mass of molten glass and is deflected through a small angle, the draw then being continued in a vertical plane. In the construction shown in Fig. 1, the sheet 3 is drawn vertically upwards from a mass of glass 1, and after passing between edgegripping rolls 6, it is deflected through a small angle 7. It then passes over a roller 8 and continues upwards in a vertical plane into a lehr. The roller 8 flattens the sheet but it may be provided with a pattern to produce figured glass. In a modification, a flattening-roller 10, Fig. 3, is arranged above the edge rolls 6, and the sheet is deflected over this roller to a second flattening. roller 12 whence it proceeds in a vertical plane. Other rollers may be used to press the sheet against the rollers 10, 12. The edge rolls may be dispensed with, and the deflecting or flattening rollers may be reduced in diameter at their ends to permit the passage of the thickened edges of the sheet. In another modification, the flattening-roller may be replaced by stub rolls. Skew rolls co-operate with the stub rolls and exert a lateral stretching-action on the sheet. In a further modification, the edges of the sheet are gripped by endless chains 27, 28, Fig. 14, which cause the sheet to travel in the desired direction. The frames 25 by which each set of chains is carried are mounted on adjusting-screws so that they can be tilted to exert a lateral stretching-action on the sheet.

Abstract: 144,518. Mortier, G. A. Aug. 29, 1919. Oscillating-cylinder pumps; actuating pumps by hand and foot power.-In pumps especially applicable to the inflation of tyres and in which the operative stroke of the piston is obtained by the flattening of a toggle-joint which the piston-rod makes with a treadle or hand-lever, the pump barrel as it turns on its pivot is caused to advance to meet the advancing piston on the expulsion stroke. As shown in Fig. 7, on pressure being applied to the plate 9 the piston-rod 17 is caused to advance in the pump barrel 12 by reason of the cross bar 11 travelling in the slots 16. At the same time, the barrel in its descent comes for. ward to meet the piston connected to the rod 17, by reason of the eccentric pivoting 6 of the end of the pump barrel, the pivot 6 being contained within the slot 22, and in virtue of the connecting-link 23. A spring 19 returns the parts to their original positions. The air delivery pipe is connected at the end 18 of the barrel. In a simpler form, the slot 22 and the link 23 are omitted. A further modification is shown in Fig. 8 in which the eccentrically pivoted pump-barrel advances towards the piston by means of teeth engaging the rack 24.

[Class 49] [Also in Group XIII] In an oven for drying and /or smoking meat, fish, &c. of the kind comprising a tunnel 1 through which the food is carried on trucks 2 having cross-walls 3 to provide flues through which the drying air and/or smoke fumes pass transversely across the tunnel. the inlet and outlet openings for the gases are so arranged that the latter make at least two passes of the tunnel and that, in each of the opposite walls, an imperforate portion, of a length at least equal to the distance between successive crosswalls 3, exists between an inlet opening and the next following outlet opening in the direction of gas flow. The invention is described as applied to an oven in which drying, smoking, and cooling are carried out in succession by hot air, smoke fumes, and cooling air supplied respectively through inlets 7, 20 and 33 in the top wall of the oven. The drying air is divided by a plate 8 into two streams which pass downwardly through adjacent trucks 3 to flues 11, 15 and thence reenter the tunnel to pass upwardly therethrough to a divided outlet 13. In the next zone, a similar arrangement of flues 25, 26 is provided to permit two streams of smoke fumes to make a double pass of the oven from the inlet 20 to the outlet 29. The cooling air traverses the goods once only during its downward travel from the inlet 33 to the exit 35.
