A wagon-handling mule has a carriage 15 on a track 14 disposed between the rails 10 of a wagon track, and a beam 17 movable between a wagon engaging position and a retracted position wherein the mule can pass a wagon, the weight of the beam initially opposes and finally assists its movement from one position to the other and the reaction loads resulting from moving a wagon, hold the beam in the wagon engaging position. The beam 17 has rollers 18 running in slots 19 in the carriage 15 and is pivotally connected by a lever 20 to wheel axle 16. Two arms 21, Fig. 2 (not shown), carrying buffer heads 22 are pivoted at 23 to the beam and are connected by links 25 to lever 20 so that as the beam is moved upwards from the broken line position in Fig. 1, the arms are moved outwards to a wagon engaging position in which they engage abutments 24 on beam 17. Rollers 27 on two arms 26 of beam 17 co-operate with catches on the track which comprise for each roller 27, a pivoted lever 30 biased by a spring 35 to lower head 33 which is engaged by a spring-biased latch 34. In operation, with the beam 17 lowered, the carriage is moved to the right in Fig. 1 by a rope, Fig. 4 (not shown), and rollers 27 depress lever ends 32 and latches 34 engage below ends 33 to hold lever heads 31 raised. On reversal of travel of the carriage, the rollers 27 engage and are arrested by heads 31 so that beam 17 and rollers 18 are moved relative to carriage 15 so raising beam 17 and opening arms 21. A pivoted lug 36 on the carriage eventually engages part 34b of the latch to release lever 30 which disengages from rollers 27.

Abstract: 1,125,394. Printed circuits. WESTERN ELECTRIC CO. Inc. 19 Oct., 1965 [9 Nov., 1964], No. 44155/65. Heading H1R. A method of making a thin-film circuit comprises forming on a substrate in succession a resistor layer, a protective layer, and an electrode layer, and sequentially etching the layers to form the circuit, the protective layer serving to protect the resistor layer during etching of the electrode layer. As shown, Fig. 1B, a substrate 11 of glass, ceramic, glazed ceramic, &c., has the following layers deposited thereon in a continuous vacuum process: a sputtered resistor layer 12 of tantalum nitride; a protective layer 13 of sputtered tantalum pentoxide, or a mixture of tantalum, tantalum nitride, and tantalum oxide; an electrode layer 14 of tantalum; a highly conductive layer 15 of gold, copper, palladium, &c. When tantalum pentoxide is used for layer 13, tantalum layer 14 is sputtered on, so that high energy Ta atoms will perforate layer 13 and reduce its resistance to a negligible value. A first resist is applied to highly conductive layer 15 and the layer is treated with a first etchant, such as aqua regia or ferric chloride, to produce a pattern of contact and connection areas (Figs. 2A, 2B, not shown); induetors are formed at this stage if desired. The first resist is removed, and a second resist is applied to the conductive pattern and the areas of electrode layer 14 to be retained, followed by a second etching step, using e.g. an aqueous solution of nitric and hydrofluoric acids, (Figs. 3A, 3B, not shown). The second resist is removed, and a third resist applied in its place, and also to the areas of resistive layer 12 to be retained. Unwanted areas of layers 12, 13, are now removed, as with hot sodium hydroxide (Figs. 4A, 4B, not shown). After removal of the third resist, the exposed electrode area 14, which forms a lower capacitor electrode, is anodized at 32, Fig. 7B, to provide a dielectric layer; alternatively, a dielectric layer may be deposited. An upper electrode and lead layer 40, e.g. of gold, is applied, and the values of resistors are trimmed by anodization, as at 31a.

Abstract: 1,132,096. Synthetic zeolites. UNION CARBIDE CORP. 19 Oct., 1965 [19 Oct., 1964], No. 44157/65. Heading C1A. A crystalline zeolitic molecular sieve is produced by treating at 20-120 C., at least partly under autogenous pressure, an aqueous reaction mixture containing a kaolin-type clay which has been rendered amorphous to X-rays and then contacted with an aqueous mineral acid to increase its SiO 2 /Al 2 O 3  ratio to 6-270. The clay may be kaolinite, livesite, nacrite, dickite, endellite, or halloysite, of general formula Al 2 O 3 . 1À9-2À2 SiO 2 . 2-4H 2 O. It is rendered amorphous by calcining at 550- 850 C., e.g. for at least 45 mins, in air or moving N 2 , C0 2  or HCl, or by attrition (various mills listed). The clay preferably has an average particle diameter of 0À2-50Á. The acid may be HCl, H 2 S0 4 , HN0 3 , or H 3 P0 4 , and treatment may be continued until the SiO 2 / Al 2 O 3  ratio is that required in the reaction mixture. (Alternatively, the ratio may subsequently be adjusted by adding Al 2 O 3 , SiO 2 , or Na aluminate or silicate, together with the NaOH and H 2 O). The clay is then washed, dried at 100-120 C., and fired at 550-825 C. in air or N 2  for 1-24 hrs (this step is essential when the product SiO 2 /Al 2 O 3  ratio is greater than 3). The process may be used to prepare zeolites A, X or Y. For zeolite Y, the reaction mixture may have the composition: Na 2 O/SiO 2  0À75-1À0 0À4-0À6 siO 2 /Al 2 O 3  6-30 or 6-30 H 2 0/Na 2 O 40-60 20-60 It may be treated in two stages, viz. digestion at 20-55 C. and crystallization at 75-120 C., and the zeolite is then separated and dried. Reference has been directed by the-Comptroller to Specification 1,007,853.

Two types of filter structure are described. In Figures 2 and 3 the filter structure comprises an endless belt 2 mounted on guide rollers 12 and having an inner run providing a generally annular filter surface 2 and an outer return run. The rollers 12 may be fast with the belt and slidably engaged in guide slots 9, 10 in the crowns or they may be rotatably mounted in the crowns for passage of the belt over their surfaces. The belt is driven by rollers 7, 8 so that it moves relative to rotating structure 1. The result of this is that solids collected on the inner filtering surface, of the belt are thrown off onto casing 16 by centrifugal force on the return run of the belt. The embodiment of Figures 8 and 10 describe a filter structure formed by a plurality of contiguous arcuate filter - elements 24 each rotatably mounted by pivots 29 in the upper and lower crowns and each having an offset pawl 26 mounted for engagement with slots 27 in reciprocating annular plate 25. During filtering, the elements are maintained as shown in Figure 8 but, for discharge of solids, the plate 25 is angularly moved relative to the rotary structure so as to pivot the filter elements. Each filter element is formed as a sealed cell with an outlet for filtrate in its lower pivot and the baffle means 4 forming a back wall for the cell. The illustrated filter apparatus has a tangential material inlet 15 and a tangential filtrate outlet 17a.
