Abstract: 799,508. Disinfecting apparatus. COIGLEY, S. M. July 20, 1956 [July 22, 1955], No. 21224/55. Class 81 (1). [Also in Group XVII] A container 10 for disinfecting a feeding bottle 11 in a sterilizing liquid has a closure member 15 that can enter the container to reduce its volume and so cause the sterilizing liquid to rise and expel any air in the container through a closable vent. As shown, the closure member 15 has a frustoconical underside 17 rising to a central vent opening 22 provided with a closure cap 23 or a non-return valve. Liquid expelled through the vent 22 collects in a gutter 25 formed by the upper surface of the member 15.

Abstract: 846,081. Ladders. ROBERTS & CO. (ENGINEERS) Ltd., D., and LESTER, S. V. Oct. 26, 1956 [July 26, 1955], No. 21550/55. Class 20(2) A non-slip device for attachment to of each stile of a ladder near the foot comprises a member 6 to which there is-pivotally mounted for limited angular movement a sprag 7 which protrudes somewhat below the foot of the stile. The sprag 7 has a serrated lower edge 13. The pivotal movement of the sprag 7 is limited by a peg 15 in the member 6 engaging a slot 14 in the sprag. In use the foot of the stile 11 normally rests upon the ground and the sprag 7 rests with one corner on the ground as shown in Fig. 3. When the ladder starts to slip the sprag digs into the ground, rocks about its point of contact with the ground so that its pivot lifts the foot of the stile slightly thereby transferring all the weight to the sprag, as shown in Fig. 1. Two of the devices according to the invention of opposite hand to each other may be attached to the foot of each stile of a non-extending ladder so that it is immaterial which face of the ladder is in front.

Abstract: 801,363. Strip annealing furnaces. SURFACE COMBUSTION CORPORATION. Aug. 27, 1956 [Aug. 26, 1955], No. 21558/57. Divided out of 801,362. Class 51 (2). In the apparatus for continuously annealing strip metal disclosed in Specification 801,362, the design of the trough-shaped inlet member is varied. Fig. 10 shows, in a plenum chamber 96, an inlet member 95 formed with a series of ports 99, which may be continuous or may be interrupted peripherally. In a modification, Fig. 11 (not shown), the trough-shaped inlet member is retained, but the side openings are connected to conduits supplied with controllable quantities of pressure air. Another modification, Fig. 12 (not shown), has the trough-shaped inlet member, with its main inlet and auxiliary side openings disposed in separate plenum chambers. A further modification, Fig. 13, has an inlet member 117 formed with three frusto-conical coaxial funnels 122 leading to side apertures 123 in the chamber 121. Two funnels only are provided in another modification, Fig. 14 (not shown). In order to prevent the backward flow of cooling air from the cooling chamber into the heating chamber, the plenum chamber 69, Fig. 15, is provided with an upper baffle plate 141 carrying a conduit 136 and nozzles 137, supplied through a pipe 140 with air extracted from the plenum chamber 69 by a pipe 138 and a pump 139. Jets from the nozzles cause a localized air flow around the baffle plate, preventing backward movement of the cooling air.

Abstract: 238,716. Siemens Bros. & Co., Ltd., and Ferreira, L. de M. G. Sept. 16, 1924. Visual outdoor signals.-In an electricallyoperated signal the reduction gearing between the motor and signal is of sun-and-planet type and comprises two planet wheels 9, 10 of the same diameter and number of teeth, respectively gearing with sun wheels 7, 8 which have equal diameters but slightly different numbers of teeth. Wheel 7 is secured to a signal shaft 6. Wheel 8 is loose thereon and carries a notched disc 11. The wheels 9, 10 are secured to a common spindle carried on a wheel 5 driven by a pinion 4 on the shaft of a motor 3. The gear wheels are mounted in a casing compartment 1 partly filled with oil. The motor 3 is housed in a second compartment 2, containing other electrical equipment and into which shaft 6 extends. Pivoted at 12 in the partition wall is a lever, the short arm 13 of which carries a roller 14 engaging the notched disc 11, the long arm 15 carrying the armature 16 of an electromagnet 17. The notches in disc 11 are so formed that roller 14 is moved out of the way by anti-clockwise rotation of the disc, Fig. 2. if magnet 17 is disenergized, but is held in engagement to arrest the disc 11 and wheel 8 when the magnet is energized. The signal arm operated by shaft 6 is held in and returned to " danger " by a balance weight (not shown). If wheel 8 is free, motor 3 is ineffective to drive shaft 6, and the signal is under control of the balance-weight. When magnet 17 is energized so that wheel 8 is arrested, the motor serves to move the signal to " clear " with a differential reduced motion depending on the difference in numbers of teeth on wheels 7, 8. Return of the signal to " danger " is retarded by a dash-pot comprising a cylinder 21 at the bottom of compartment 1 to which the oil has access, and in which works a piston 22 with check-valve 27, connected by a rod 23 to a pin on wheel 7. A restricted passage 24 in the wall of the cylinder 21 communicates between the lower and upper sides of the piston. Contact arms 19 for control of the motor, detector circuits, &c. are carried on the signal shaft in compartment 2 and cooperate with fixed bent spring contacts 20. According to the Provisional Specification, a spring connection may be provided between the wheel 8 and disc 11.

Abstract: 484,983. Coating with metals. SCHREIBER, F., and METAMINE GES. Aug. 11, 1936, No. 22062. [Class 82 (ii)] Iron plates &c. treated with an aqueous solution of iron and acid-free chloride of zinc are introduced into a heating chamber to produce a crust of zinc chloride on the articles which pass automatically into a zinc-lead bath, the zinc layer of which is maintained free of oxides and hard zinc and is mechanically freed from slag. When in the lead the articles are turned into a vertical position and as they rise to the surface they are freed from the zinc chloride crust and, after coating by passage through the zinc layer, are conveyed to a cooling device. In the preferred apparatus vats are provided for the preliminary treatment, that holding the zinc chloride being made of or lined with lead or copper and the articles are carried through the heating chamber 20 by a chain conveyer 19 and passed by heated rollers 22, 25, 30 into a V -shaped guide 44 immersed in the lead. Teeth on the lower rollers swing the article 1 to the other side of the guide and it rises between rollers 48 and divergent plates 47 which remove the zinc chloride crust and guide it clear of the path of the article. Rolls 51, cleaned by brushes 91, and additional rollers 52, 53 all of which are internally cooled carry the articles to a conveyer 72 leading to a rotary cooling rack. The surface of the zinc between the upper ends of the plates 47 is freed from slag by paddles 58, 58a, Fig. 3, reciprocated by a rotary disc 68 and connecting rod 67, and also raised and lowered by cams 63, 63a. The zinc layer 27 is kept free from impurities by periodic deoxidation treatment and by the provision of a ceramic coating for the metalwork of the bath 29 and of a fireclay lining backed by heat-conducting material at the zinc-lead juncture. Specifications 426,868 and 450,690 are referred to.

Abstract: 1396814 Rolling mills WEAN UNITED Inc 9 May 1973 [5 June 1972] 22146/73 Heading B3M A rolling mill is provided with an adjustable spacer assembly between the chock 12 of a roll 11 and the adjacent housing 10, the assembly including two stepped spacers 17 and 18. The spacer 17 has relatively small steps 19, and the spacer 18 larger steps 21. By choosing a suitable combination of thickness of the two spacers, a desired distance between the chock and housing may be obtained. This is useful for maintaining a desired pass line when changing the mill rolls. Each spacer is axially movable to bring a desired step between the housing and chock. Bars 23 and 24 are coupled to the spacers for this reason and are engageable by retractable pins 54 and 55 (Fig. 2), coupled to cylinders 61 and 62. To move the spacer 17, for example, the pin 54 is engaged with bar 23, and the cylinder 61, together with the bar and spacer, is shifted by a ram 63, Fig. 1. Before the bars can be moved, however, the chock 12 is lowered to leave sufficient room for the spacers to move between a load cell 16 and a block 15. Protective housings 43 and 38 are coupled to the housing and block 15, the housing 38 also carrying longitudinal guides for the spacers. Similar spacers for the second housing of the mill may be connected to the same bars 23 and 24, such that both spacer assemblies are adjusted simultaneously.
