Title: Magnesium-based coatings for the sacrificial protection of metals
IPC: C23C12/02
Filed: 1972-04-14
Abstract: 1348201 Forming magnesium silicide CHROMALLOY AMERICAN CORP 14 April 1972 [17 May 1971] 17327/72 Heading C1A [Also in Division C7] A substrate is provided with a Si-containing coating and then subjected to pack diffusion coating in a Mg-containing pack containing a small amount of halide energizer whereby a coating containing Mg silicide is formed thereon. The substrate may be steel, Al, Al alloy, Ti, Ti alloy, or a ceramic such as Al 2 O 3 , and may be cleaned, e.g. by honing with powdered Al 2 O 3  prior to applying the Si-containing coating, which is typically applied from a solution of Na, K, Li or ethyl silicate by dipping or spraying followed by drying and curing, e.g. at 400 F; more than one coat may be applied. The pack may contain 5-100 wt. per cent Mg, up to 95% inert diluent (ZrO 2 , TiO 2 , HfO 2 , ThO 2 , rare earth oxide, SiC, TiC, WC, or preferably Al 2 O 3 ), and -5% halide energizer, e.g. an ammonium halide or metal halide, e.g. AlCl 3 , or halogen such as I 2 ; heating in the pack is for -60 hours at 700-1000 F.; a coating 0À2-1 mil. thick may be formed containing typically 20-60 wt. per cent Mg, Si, oxygen, and possibly substrate material. A Si-containing coating may be deposited on this coating and cured, as described above. The coatings so formed provide sacrificial protection for metals in marine environments.

Title: Improvements in or relating to machines for laying stripping on insole blanks
IPC: A43D43/06
Filed: 1957-05-31
Abstract: 846,296. Applying ribs to insoles. PRIME MANUFACTURING CO. May 31, 1957 [March 1, 1957], No. 17430/57. Class 17(1) A machine for laying rib stripping 14 around insole blanks 15 comprises insole supporting means 11, means for guiding the stripping and feeding the work so that the stripping is laid progressively around the insole, and means for severing the stripping on completion of the laying operation which comprises a movable knife, a source of power for driving the knife through the stripping, and a power release control movable for releasing driving power to the knife when required. As shown, the machine includes feed feet 12, and a stripping guide foot 13 which is lifted on a rocker member 16 rearwardly and outwardly at completion of a strip applying operation, and the supporting means comprises a freely rotatable roll 11. When treadle 33 is first depressed, it acts via rod 32, adjustable head 31, rod 30, lever arm 29, adjustable link 28, and lever arm 26, which is normally held in elevated position by spring operated rod 27, to rotate shaft 25. Hence via arm 24, rocker 23, and link 22, slide 19 with serrated knife blade 20 is advanced in guideway 18, the movement of the slide also causing the gripper jaws 21 to close, and via arm 40, link 41, and rocker member 16 the guide foot 13 is retracted. Continued movement of the treadle acts via rod 32, adjustable connection rod 34, and switch arm 35 to trip the switch 36 of solenoid 37, the core 38 of which is connected via yoke 39 to lever arm 29, so that the knife is then power operated. On release of the treadle the spring operated rod 27 returns arm 26, thus advancing guide foot 13 to operative position and retracting slide 19 with knife 20, the slide also acting by means of a pin and slot connection to open the jaws 21.

Abstract: 372,592. Clockwork-actuated valves. GUNNING, J., 100, Holdenhurst Road, Bournemouth. June 16, 1931, No. 17470. [Class 135.] An apparatus for automatically operating gas valves by clockwork has a readily detachable clock case 2, 2a provided with studs 12 adapted to be held in holes or slots in an arcuate strip 10 formed on the cock body, by a catch 13 pivoted at 14 to the clock case and provided at the other end with a hook adapted to engage a pin 16 on the cock body. The catch may be secured in position by a nut 17 screwed on the pin 16 and by a screw 19 in the clock case. When the clock case is formed with parts of different diameters the arcuate strip is arranged to fit the shoulder between these parts. The clock spindle 3 carries a 24-hour dial fitted with adjustable tappets adapted to co-operate with a star wheel 5 on the cock plug. To enable the timing dial to be set while the clockwork mechanism is detached a pointer 19 is secured to the clock casing which registers with the usual fiducial point 20 on the cock when the 'parts are put together. To further facilitate removal the hinge 21 of the outer casing cover is slotted so that the cover of the casing can be unhooked from the body part 1.

Title: Improvements in the method of gumming paper
IPC: B05C5/02
Filed: 1933-06-20
Abstract: 402,007. Liquid-distributing nozzles. CHAMBON, Ltd., Riverside Works, Standish Road, Hammersmith, London.-(Assignees of Anciens Etablissements L. Chambon; 64, Rue de CrimÚe, Paris.) June 20, 1933, No. 17570. Convention date, Feb. 17. [Class 69 (iii).] Apparatus for applying substances such as gum to a web of material such as paper or cardboard comprises a nozzle having an opening through which the gum emerges on to the paper and means for automatically shutting off the supply of gum when the nozzle is lifted from the paper. Gum in a container 4 descends through a neck portion 5 and exudes on to the web 1 through a nozzle 6 provided with a narrow slit 7. A needle valve 8 contacting with a seat 9, passes through a washer 10 and is jointed to a lever 12 pivoted at 13 which is adjustable by means of a screw 14 spring-pressed against an eccentric stop 15. The pressure of the nozzle on the paper is varied by means of a screw 20 which co-operates with a frame 18 pivoted at 22 and supporting the container 4 and an arm 19 which is keyed to a shaft 23 integral with an arm 24 carrying a roller 25 bearing on a cam 26 at the extremity of a lever system 27, 31 actuated by a bar 30. Movement of the bar 30 in the direction of the arrow causes rotation of the container 4 round the shaft 23 and movement of the nozzle 6 away from the web 1. Simultaneously the flow of gum is interrupted by the forward movement of the lever 12 and needle valve 8 under the influence of a spring 17 and is re-established by the reverse movement. In a modification the needle valve 8 is replaced by an inverted cone applied to its seat in the opposite direction to the flow of gum so that gum is sucked away from the outlet and ensures a clear finish to the line of gum on the web.

SAUNDERS. April 30, 1962 [May 17, 1961], No. 18020/61. Heading B8B. [Also in Division E1] Digging or material handling apparatus especially for use in dredging comprises a framework 1 and a jib 3 running on a circular track 2b and provided with a track 4 for a carriage 5 supporting a grab 6. The carriage 5 has wheels 8, 9 and pulleys 7 over which ropes 11, 13 pass from an attachment 12 on a grab extension 15 and from pulleys 14 of the grab opening mechanism respectively on their way to a crosshead 21 of a loop compensator and to winding drums 18a, 18b. On starting the motor with the grab in its uppermost position having emptied into a shoot 2a over a conveyer belt or receptacle the ropes 11, 13 pay out together the drums 18a, 18b being clutched together and the carriage 5 moves down the track 4 until the wheels 8 contact stops 4c causing it to pivot and the wheels 9 to enter a turnout 10 in which position the carriage becomes locked. Further winding out of the ropes lowers the grab into the digging position where the relieving of weight allows the compensator pulley 23 to descend and strike the arm 27 of a control mechanism thus de-energizing the motor, applying the brakes, and disengaging the clutch between winding drums 18a, 18b. The motor immediately starts in the opposite direction and the drum 18b draws the crosshead 21 upwards closing the grab through ropes 13 and slackening the ropes 11 until at a predetermined time the clutch is re-engaged and the grab rises until rollers 16 enter the mouth 17 of a slot 19 causing the carriage 5 to pivot back and then up the track 4 until an arm 29 of the control mechanism is struck. The motor is thus again de-energized, the brakes applied, the clutch disengaged and the motor re-started in the opposite direction which causes the drum 18b to open the grab and when it is fully open the clutch re-engages and a new cycle can start. In a modification a purchase is introduced into the closing rope between the drum 18b and the pulley 25 and this can be used in place of the clutch.
