Title: Improvements in or relating to capacitors
Inventor: HERBERT JOHN MARTIN
IPC: H01G4/008
Filed: 1959-05-26
Abstract: Electrodes for capacitors comprising ceramic dielectrics sintered or bound in organic plastic material are formed by spraying or printing thereon a composition containing zirconium metal, the dielectric material, tin, and nickel, iron, or cobalt; to obtain improved adhesion of electrode to dielectric, and of the soft solder for attachment of the electrode leads, and also to increase the diffusion of gases (e.g. oxygen) through the capacitor unit.  The component materials, with tin and nickel &c. in the form of the oxides, are ball-milled to a powder with an organic binder (e.g. cellulose aceto butyrate) and a solvent, and sintered so that the binder is destroyed and the oxides are reduced to metals which diffuse one into the other and bond to the dielectric particles.  Proportions of the ingredients are given.

Title: Improvements in stockings and socks for wear and in the method of manufacturing same
IPC: D04B9/46
Filed: 1943-11-06
Abstract: 576,662. Knitting. BERRIDGE & CO., Ltd., I. L., and COLTON, L. H. Nov. 6, 1943, No. 18457. [Class 74 (ii)] A full-fashioned stocking blank made upon a straight-bar machine has a heel portion at each side formed with a suture a f extending from the end of the instep to a position short of the selvedge. Knitting is discontinued on the instep needles and knitting proceeds on a gradually lessening number of needles, the inoperative needles holding their loops; subsequently the heel needles are gradually introduced and finally the heel and instep needles all knit. An additional suture may be formed by reducing the number of heel needles knitting from k to o, increasing the number from o to m, again decreasing from m to l, and finally increasing from l to k when the instep needles also are introduced. A toe having a suture p, q may be formed on the instep needles, by reducing and subsequently increasing the number of needles knitting, the heel needles holding their loops. The appearance of the suture may be varied by knitting two plain corners upon all the needles immediately following the course at which fewest instep needles knit. Alternatively the suture "holes" may be filled in by forming tuck stitches upon needles as they are brought into operation. Sole narrowings 2a may be provided. A divided needle bar or presser bar may be provided so that the instep needles can be withheld from knitting during the formation of the heel parts and the heel needles 10 are restrained from pressing by instruments 17 depending from brackets 18 which can be racked as desired parallel to the needle bed and can be moved downwards to bring the instruments into engagement with the needle heads to push the needles away from the presser bar 12. The thread carried is controlled to give the desired shape of heel parts.

Abstract: 796,103. Cycle frames. ATELIERS DE LA MOTOBECANE. June 29, 1955 [July 20, 1954], No. 18851/55. Classes 136(1) and 136(3) A shell frame for an auto cycle consists of three principal prepared components, namely: two side shell pieces 1, 2 joined on a central longitudinal plane x-x, and a front shield 3 joined to the two shell pieces on a transverse surface y-y. The shell pieces 1, 2 and the shield 3 are joined by means of connecting lips 4, 5 permitting electric seam welding. After assembly the lips 4, 5 form strengthening fins. The shell frame is completed by leg shields 6, 7 secured to the connecting lips 5. The front shield 3 includes at its upper part a deep depression 8, the parallel upper and lower bounding walls of which are used as fixing surfaces for bearing sleeves for the steering pillar. An opening 11 is formed in the shield 3 for the insertion into the interior of the frame of the fuel tank 12 having a filler cap 13. Alternatively, the tank 12 may be made of two sheet metal shell pieces joined in a central vertical plane coinciding with the connecting lips 4 of the shell pieces, 1, 2 of the frame. The connecting lip of one of the two shell pieces forming the tank may be wider than the lip of the other shell piece (Fig. 12) so as to come between the connecting lips 4 of the shell pieces 1, 2 and be joined in the course of the same seam welding operation. The frame has a rear extension 14 reinforced by an internal wall 15 which has substantially the shape of a normal mudguard and which converts this part of the shell frame into a closed tubular beam. The shell piece 1 has a recess 19 in which lies the chain wheel of the pedal assembly 18, the upper run 21 of the chain passing through an opening 20 formed in the wall of the recess 19. A bearing housing 23 for the pedal assembly 18 serves the additional purpose of strengthening the tie between the two shell pieces.

[Class 38 (v)] In a mercury switch in which energization of an electromagnet 10, causes the descent of a floating member 34 and the consequent raising of the level of mercury 33 to engage the bared end 32 of an insulated electrode, the end 32 is bent over to extend below the level of the insulation. The member 34 comprises a magnetic sleeve 37 and a tube 38 of refractory material, loosely fitting over each other and held in place by helical springs 39, 40 which grip the projecting end of the inner member and serve also as buffers. The tube 38 may be of glass, quartz, or ceramic material. The mercury container is evacuated or filled with helium, hydrogen, helium hydride or other gas. In a modification, Figs. 6, 7, (not shown); the tube 38 is closed at the top and made of porous ceramic material which only allows gas to escape slowly through it. This gives a time-delay action to the switch. Specification 433,773 is referred to.
