Title: Improvements relating to the actuation of electronic yarn cleaners
IPC: G01N33/36
Filed: 1964-09-30
Abstract: 1,082,059. Yarn thickness monitoring; measuring electrically. ZELLWEGER Ltd. Sept.30, 1964 [Oct.1, 1963], No.39839/64. Headings G1A and G1N. In an electronic yarn-cleaning apparatus, an electrical quantity U 1 , corresponding to the crosssection or diameter of yarn passing through a measuring element 1, is supplied to two or more channels, each responsive to a signal-variation characteristic of a particular fault, to produce, when an adjustable threshold value for any channel is exceeded, a further signal to actuate a cutting device 3. Thus, threshold switch 2 in one channel responds to a thickening of the yarn above a set tolerance, while a lesser thickening, if prolonged beyond a set length, produces in an integrating device 4 in a parallel channel a signal which actuates a threshold switch 5 to operate the cutting device 3. Device 8, in another parallel channel, may be arranged to respond to the falling of the yarn thickness below a particular value. To prevent actuation of switch 5 when a yarn is inserted in the measuring element 1, a control element 6 closes a switch 7 to disable switch 5 while the signal U 1  is constant; switch 7 does not open until U 1  displays the normal variations of a running yarn. However, should a thickened end of the yarn be inserted in the measuring element 1, the signal output from 4 over-rides the disabling effect of switch 7 and actuates switch 5. The measuring device 1 may be of the optical, capacitative, or other type. The threshold values of the various channels are adjustable by a first control (count control) which acts on U 1  and influences all the channels, and by individual controls (percentage controls) which determine the sensitivity of each separate channel. Threshold switch 2 may be formed by a Schmitt trigger circuit and may be combined with threshold switch 5 and devices in other channels Fig.2 (not shown). Circuits for control element 6 and switch 7 are depicted in Figs.3 and 4 (not shown).

As the transport means advances, the arms 46 swing down so that the rollers 56 ride down the lower surfaces of legs 96. On the return movement, the rollers 56 ride up the upper surfaces of legs 96 and since the upward swinging of the arms 46 is limited, the lowering mechanism is forced downwards, together with the plate 18 and the members 104. When a sloping portion 116 of each member 104 contacts the top plate of a stack resting on the bottom wall 28 of the magazine, or contacts the wall 28 itself, the members 104 are moved outwards to deposit the plate 18 on the stack or on the wall 28.

Title: Refractory materials resistant to corrosive melts and a method of treating them
IPC: C04B41/85
Filed: 1957-12-24
Abstract: Shaped refractory articles obtained from magnesia, e.g. bricks for use in the walls of electrolytic cells, are made more impermeable and resistant to chemical attack by corrosive melts, e.g. cryolitic baths, by impregnating the articles with a substance capable of "wetting" the articles and containing a major proportion of cokifiable hydrocarbons, and subsequently heating the impregnated articles under coking conditions. Impregnation is preferably with hard pitch, i.e. one of softening point at least 70 Kramer Sarnow (KS) degrees, a temperature of 200 to 220 DEG C. being maintained until adequate penetration of the pitch is achieved, after which the pitch is coked at about 600 DEG C. in the absence of air, e.g. in a nitrogen atmosphere.  After cooling, removal of the coke layer formed on the surface of the articles facilitates further impregnation and coking if desired.  Three to five impregnations are said to be sufficient.  Soft pitch of 45 DEG KS can be used to impregnate at 180 DEG  to 200 DEG C., subsequent impregnations if desired being effected with hard pitch.  The coke content of the refractory may be 4 to 5% by weight.  Examples illustrate the effect of fused baths containing cryolite, alumina, and fused aluminium upon bowls made of magnesia bricks treated in accordance with the invention, or untreated.  Specifications 800,092 and 814,754 are referred to.
