Title: Improvements in or relating to glass feeding devices
IPC: C03B7/096
Filed: 1937-11-09
Abstract: 505,440. Glass manufacture; weighing- apparatus; antomatic control systems; switches. WOOD, J: T. Nov. 9, 1937, No. 30744. [Class 56] [Also in Groups XVIII, ' XXXV, and XXXVII] In a device for feeding glass in gobs to a machine from a forehearth &c. the temperature of the glass is controlled by apparatus for weighing the gobs or the articles made from them. In one arrangement, Fig. 3, the valves such as 4 for controlling the feeding plunger (not shown) in accordance with the weight of the gobs or articles as described in Specification 500,807, are provided with pawls or racks for driving threaded spindles such as 25 stepby-step. In due course a nut 26 on the spindle operates a switch 28 to drive motors 37, 38 controlling the burners or dampers in the appropriate direction. The nut also operates means whereby the spindle and nut are restored to normal by fluid pressure means. Alternatively the spindle may be driven by the solenoids controlled by the valves or by a motor. Similar apparatus is providedfor control by the other valve. In a modification, the switch 28 is actuated by a cam on a shaft driven by a valve such as 4 or by a solenoid. In a further modification, Fig. 6, the weighing device controls driving solenoids 68 of step-by-step switches which complete the heat-increasing and heat-decreasing circuits after a pre-determined number of steps.

[Class 35.] Exciting.-A single armature counter-compound wound welding generator has two field systems spaced along the armature, one series excited, and the excitation of the other depends partly on the generator voltage and partly on that of an independent source. In the form shown, the opposing series winding SM1, SM2, SM3 with the small winding HM2 is placed on the auxiliary field system whilst the main winding HM1 on the main system is energized through a potentiometer P1, P2 connected to the armature A1 and to an exciter A2. The number of series turns is variable and when a maximum, a counter compound winding SM5 on the main system is also effective, whilst a cumulative compound winding SM4 on the main system is effective when section SM2 is cut out. In a modified form the exciter with a resistance is connected in parallel with the generator and the main field winding is connected between the common terminal of the two machines and an intermediate point on the resistance.

Title: Improvements in or relating to pumphead valves
IPC: F04B53/10
Filed: 1935-11-08
Abstract: 462,921. Non-return valves. JONES, W. Nov. 8, 1935, No. 30957. Convention date, Nov. 8, 1934. [Class 135] In an arrangement of valves for a pumphead, each valve is in the form of a freely floating disc 12 resting when closed, directly on the deckplate 10 over an opening 11 therein and guided for limited free movement by a one piece cage 13 also resting directly on the deckplate, the cages being anchored by means 18 mounted on the deckplate. Fig. 1 shows an assembly of six valves. The cages 13 are anchored by a double spider 18 secured to the deckplate 10 by screw bolts 19 and nuts 20 beneath which are split washers 21. Where the valve seats are flush with the deckplate, as in Fig. 3, lateral movement of the cages is prevented by interengaging teats and recesses 23 on the heads of the cages and the spider arms. These teats and recesses are however dispensed with in another form in which each opening 11 has an integral upstanding valve seat portion surrounded by a step or shoulder for the cage ring 14. The bosses 17 on the cages are made thick enough to be machined down if it is desired to increase the valve lift. The Specification as open to inspection under Sect. 91 describes also a valve having a separate externally tapered seat member mounted in the deckplate. This subjectmatter does not appear in the Specification as accepted.

[Class 80 (ii).] The strikers b, c for the change-gear elements are slidably mounted on fixed guide-bars d, e and are normally locked thereto by spring pawls m, n. The locking parts o, p of the pawls and the notches s .. x in the bars with which they engage are rectangular in section to prevent disengagement by lateral pressure. The enlarged head i of a selector control lever a passes through a slot l in a fixed check strip k so as to engage between a pair of cheeks g on striker b, or between like cheeks h on striker c. The head i must strike pawl m or pawl n and positively disengage it from the bar before the striker can be moved away from neutral by pressure on one or other of its cheeks. A stop z is provided to prevent striker n from being moved from high-speed notch x beyond neutral notch w to reverse notch v. To move striker c to reverse, the pawl n must be purposely set to pass between stop z and a cut-away part y of bar e. The pawls instead of being pivoted, as shown, may be of the sliding type.

Filed: 1965-07-21
Abstract: A method of etching or dissolving an alkali-soluble glass coating (i.e. a glass coating having a silica content of from 20 to 100% by weight) from a glass-coated wire made of a base metal comprises preheating a bath of molten alkali, e.g. at about 350 DEG C. for at least 500 hours, in an extremely dry inert atmosphere of protective gas or in a vacuum to drive out the oxygen and water content of the melt and then drawing the glass-coated wire through the molten alkali while maintaining the inert atmosphere or vacuum. The residence time of the wire in the bath is from 0.5 to 5 mins.  The protective gas, e.g. nitrogen with a moisture content of below 0.1% by weight, may be continuously withdrawn from above the melt and recirculated through a drying chamber. The alkali may be sodium, potassium or lithium hydroxide or a mixture of two or more such compounds.
