Abstract: 218,127. Ohlsen, J. U. Ahlmann-. July 25, 1923. Pottery; making and waterproofing bricks.- Tubes, bricks, and other articles are made by moulding a mixture of diatomaceous earth, clay, and a low-fusing flux such as alkali silicate, then baking, and finally impregnating with melted asphalt, tar, pitch, bitumen, or paraffin. The plastic articles are: preferably moulded at a high pressure, for example 100 to 300 atmospheres. The impregnation may be effected in open or closed vessels; in the latter case, the articles may be first subjected to a vacuum and be impregnated under pressure. In one example, 5 parts of dried and ground diatomaceous earth, 1 part of clay, and 1 part of flux, such as mineral meal, are moulded wet ; the articles are then dried and burned at a temperature of 1400‹ to 1800‹ F., and while still hot are dipped into or otherwise impregnated with asphalt or like material. In another example, the articles are moulded from a mixture of 10 parts of raw dried diatomaceous earth, 5 parts of burnt diatomaceous earth, 4 parts of clay, and 1 part of alkali silicate. The products are acid proof and impermeable to air and fluids.

The annular chamber is sub-divided by radial walls 4, Fig. 1, into chambers 5-11 containing a fluid-seal 12 which may be a mass of fibres of the substance having the Registered Trade Mark " Perspex " soaked in a liquid of high viscosity. Alternatively it may be a U-tube partly filled with a liquid such as glycerine or oil. Each chamber communicates with the next by a capillary tube 6a-11a, some of which are bent to form liquid traps. The first chamber 5 communicates at 5a with the liquid chamber 3 and the last with the atmosphere. In another form, Fig. 4, the liquid chamber 14 communicates with the annular reservoir 15 through a restricted passageway 19, which is formed between the bottom 17 of the bubble chamber and the bottom 18 of the reservoir. The reservoir 15 is closed to the atmopshere and communicates with the bubble chamber through a small hole 20.

Needle butts 131 of needles 13 are guided by cam parts 15, 16, 17 at each station A, B, C, D, &c. Needle jack cam 11 has three tracks engaged by driving out butt 181, retraction butt 182 and tilting butt 183 of jacks 18. Each track for butts 183 includes a resiliently mounted cam 22. Selectors 27 also lie in the tracks 252 and have vertically staggered butts 273 at different positions corresponding to pattern slides 12. A selector 27 not influenced by a slide 12 remains in working position and the associated jack 18 also remains in working position with its butt 181 in reach of cam part 19 so that it is slid upwardly to engage the -corresponding needle 13 so that its butt 13 is guided by cam parts 14 to knit. Butt 183 engages came 167 which prevents tilting of the jack. If a selector 27 is engaged by a slide 12 and pivoted in about its end 272 its corresponding jack 18 is tilted and its butt 183 engages guide track 28 and butt 181 is disengaged from cam 19 so that the jack and hence its corresponding needle is not raised and the needle butt 131 remains in engagement with cam 16. Butt 183 is engaged by cam 22 to return it to its working position.

Filed: 1959-06-05
Abstract: 858,996. Electromagnetic relays. KUHNKE, H. June 5, 1959 [June 6, 1958], No. 19340/59. Class 38 (5). [Also in Group XXXV] An electromagnet particularly for a relay has members which roll on surfaces extending obliquely to the direction of attractive movement of the armature, so as to convert the movement into a translational movement substantially perpendicular to the attraction movement. In Figs. 1, 2 and 4 the armature 4 is urged towards an E-shaped core 1 and coil 2 by springs 18a which also urge the armature to the left. The armature is spaced from the core 1 by balls 15, 16, 17 in inclined grooves in steel parts 5 . . . 10 secured to non-magnetic rails 11 . . . 14, 19, 20. When the relay is energized the armature moves to the right on the balls, closing the gap between the core and armature and also closing contacts 22, 23. In an alternative arrangement employing a solenoid-type of coil surrounding the spaced poles of a C-shaped core, the armature extends within the coil and across the gap in the core, being pressed toward the gap by a bowed leaf-spring, Fig. 6 (not shown). In Fig. 7 the armature 40 is spaced from the core 39 by balls in grooves as described above and guided by biasing-springs 41, 42. The end of the armature 40 engages the bent end of a contact-spring 43 to actuate the spring-set 43 . . . 47. The groove-bottoms may be curved so as to change the conversion ratio as the armature moves. The grooves may be replaced by slots of varying widths so that the balls sink to a greater or lesser extent as they run or the balls may be replaced by rollers.

Title: Digital data stores

Abstract: 1379185 Digital matrix stores INTERNATIONAL BUSINESS MACHINES CORP 24 April 1973 [4 May 1972] 19402/73 Heading G4C A digital store comprises an array of cells arranged in columns and a number of groups of rows. Means is provided for partially selecting the cells of a certain group of rows, for partially selecting the cells of a certain column, and for partially selecting the cells in a certain row of the selected group, whereby to select a particular cell of the array. Each cell of the store comprises cross-coupled double-emitter transistors 1, 2, Fig. 1, forming a bi-stable circuit. To change the state of a cell during a Write operation, word top line 16 is raised to the " select " voltage 1À75 V and word bottom line 18 to 1À0 V. If transistor 1 is on, bit line 20 is maintained at the " standby " voltage 1À5 V. If bit line 22 is lowered to 0À25 V transistor 2 is turned on and transistor 1 turned off, these states being maintained when the top and bottom lines are returned to the standby voltages. To Read the state of a cell, the top and bottom line voltages are raised as before, and both bit lines 20, 22 are lowered to 0À25 V. If transistor 1 is on, the curernt formerly flowing through emitter 5 switches to emitter 6 and passes to a bit line sense amplifier connected to bit line 20. Since transistor 2 is off there will be no current in bit line 22. The cells are arranged in an array comprising m columns and n rows. The columns are divided into c groups of r rows. In one arrangement (Fig. 2, not shown), a row of cells is accessed by applying the select voltage to all the word top lines of the group containing the row, and to the word bottom line of the relevant row in the selected group (and of the corresponding row in each other group). The Read or Write operation is performed on a particular cell in the selected row by lowering both or one of the bit lines of the cells in the column containing the required cell. In another arrangement (Fig. 3, not shown), the functions of the word top and bottom lines are reversed.
