The catalyst may be in the form of hard particles made by grinding cylindrical shapes having an end-on crushing strength of 1500-10,000 p.s.i.g. The coated substrate may be made by making a mixture of oxidation catalyst particles and enamel particles, forming the mixture into porous aggregates smaller than the intended coating thickness, applying the aggregates to the substrate and heating to cause adhesion of the aggregates to each other and to the substrate. The porous aggregates may be applied to the surface to be coated by spreading them dry (pre-calcined), the surface preferably having been pre-treated with a viscous liquid to facilitate preliminary adhesion of the aggregates. The aggregate may also be made up into a slip and applied by flow-coating, brushing or spraying. Conveniently a viscous slurry of the particles of oxidation catalyst and vitreous enamel is sprayed from a spray-gun to form porous aggregate particles. Preferably the substrate is at 50-150‹ C. when the coating is applied.

IPC: H02K15/06
Filed: 1967-03-10
Abstract: 1,177,807. Inserting coils in stators. INDUSTRA PRODUCTS Inc. 10 March, 1967 March, 1966; 13 Dec., 1966], No. 11392/67. Heading B3A. A tool for transferring a plurality of coils, wound and positioned on respective formers, from the formers to a device for using the coils, comprises a body portion, an alignment element fastened to the body and adapted to engage a mating structure on the formers and on the coil using device for aligning the tool therewith, and a plurality of sets of pins, comprising at least two pins per set which are correspondingly and symmetrically positioned relative to the alignment element for supporting one of the wound coils. A first embodiment of the tool comprises the body 26 and two sets, each of-four pins 27, 28, 29, 30 arranged symmetrically in the body. A clamping lever 34 pivoted to the body has two coil-retaining -hooks 35, 36 and is biased by a spring 40 towards a clamping position. The body has a handle 39 and the lever 34 has an extension 38 by which it can be turned against the spring. The extension 38 can be locked adjacent the handle by a latch 41. The pins 27, 28, 29 are positioned to enter holes 22, 23, 24 in two coil formers 14, 16 on which coils 18, 20 have been wound. The formers each consist of two parts which are moved apart for winding and are subsequently brought closer to facilitate removal of the coils. To remove the coils the tool is applied by hand to the former, the pins 27 acting purely as guide pins, the smaller coil 20 being between the pins 28 and 29 and the larger coil 18 being between the pins 29 and 30. The latch 41 is then released so that the lever 34 swings down and rests on the coils and as the tool is withdrawn the hook 35 and 36 engage the coils and draw them off the formers. The coils are next transferred to a placing machine, Fig. 6, which comprises a series of fingers 55, one for each slot of a stator into which the coils are to be inserted. Each finger has a groove 56 which receives a radial rib defining the stator slots and protects the wire of the coils from the sharp edges of the ribs. The coils are inserted axially between the fingers and subsequently transferred to the stator by the axial movement of the pusher plate 58. A second embodiment of the tool, Fig. 7, comprises a body 75 and six sets of pins, each set consisting of three pairs of symmetrically arranged pins 78, 80, 82. Coils 68 and 70 are withdrawn from formers 64 and 66, a further pair of coils is wound and withdrawn and the process repeated until a complete set of coils for a six-pole motor has been assembled on the tool, Fig. 10. The coils are then transferred directly to a stator by pushing the plunger 85.

A calculating device comprises a rule 1 with separate portions, e.g. to the left and right of a centre line 3, marked with scales for two variable factors, and a sliding member 2 having a datum line 6 and scale markings 7 and 8 for a third factor so that, by alignment of the datum line 6 according to a first factor value, correlated values of the second and third factors will be aligned opposite each other. The rule has a plurality as shown, three scales for each of the two first factors. The rule shown is for apportioning the constituents of dairy-cattle feed to maintain a certain nutritive value. The scales to the left of the line 3 relate to a first type of fodder, those to the right to a second type of fodder, and the scale lines 7 and 8 to three breeds of cattle, at maintenance level and at maintenance level increased for a yield of one gallon of milk, respectively. The slide 2 is adjusted to position the datum line 6 over the available quantity of a first constituent represented by a lefthand scale on the rule 1. The required quantity of alternative constituent is then shown by the appropriate scale marking 7 or 8 on the corresponding right-hand scale of the rule. The reverse side of the rule is marked with six similar scales, and the slide 2 with a datum line and transverse scale lines for dry matter content of the ration in place of the lines 7 and 8. The datum line is again set to the available quantity of first constituent, whereupon the dry matter content is indicated on the slidescale against the quantity of alternative constituent as already determined.

Abstract: 752,011. Photographic image-transfer method. KODAK, Ltd. April 22, 1954 [April 22, 1953], No. 11675/54. Class 98 (2). A hardened colloidal binder-silver halide emulsion layer is exposed, developed and pressed into contact with a light-insensitive receiving support in the presence of an acid solution of a, silver halide solvent and a precipitating agent, the latter being in sufficient quantity to supply stoichiometric amounts for reduction or precipitation of silver ions diffusing into the receiving support and thereby produce a reversed image therein. Acid solution lowers background yellowing of the print due to alkaline developer. In an example a hardened gelatino-silver halide emulsion is exposed to a line image, treated in a hydroquinone developer, and pressed on a receiving sheet of paper having a gelatine layer containing zinc sulphide particles and which has been dipped in potassium metabisulphite solution, to give a brown positive image of minimum stain in the receiving sheet. Alternative methods of conducting the method include dipping the developed negative into an acid silver halide solvent solution instead of the receiving sheet; inclusion of the precipitating, agent in such acid solution; use of other silver halide solvents such as sodium sulphite, bisulphite or thiosulphate and acids such as citric, acetic, sulphuric or hydrochloric; use of sodium sulphide or selenide, amino guanidine salts, arsenious oxide or sodium stannite as precipitating agents; and use of hardened silver halide emulsion layers containing developing agents such as the layers of Specification 745,445 for developing in alkali only. Specification 746,174 also is referred to.
