Title: An improved chuck or holder for use in turning or treating pottery ware
IPC: B28B1/02
Filed: 1929-12-18
Abstract: 345,240. Throwing and turning pottery. WOOD, H. F., Brampton Tree House, Newcastle-under-Lyme, and COULTER, W., 55, Newcastle Street, Burslem, Staffordshire. Dec. 18, 1929, No. 38720. [Class 87 (i).] A chuck or holder for use in turning or treating pottery ware comprises a rotary spring-influenced clamp e<\> c<2> adapted to grip the article to be treated at its base and a spring-influenced sleeve or ring d adapted to engage and locate the article at its mouth. The part c<2> of the clamp is rigidly fixed to a shaft c which may be rotated from a source of power. The part e<1> is mounted on a ball-bearing in the boss e<3> on the shaft e slidably keyed in the sleeve f, which may be moved to the left by lifting handle k and be retained by a detent i<1>. In operation the article is placed so that the member c<2> touches its bottom internally while the ring d locates its mouth. Handle k is then raised so as to move the sleeve f to the left, thereby causing the spring h incorporated between the sleeve f and the boss e<3> to press the member e<1> externally against the bottom of the article. To disengage the article the handle j is lifted, thus withdrawing the detent i<1> and allowing the weight k<6> to move the sleeve f to the right drawing the shaft e with it. The clamp member c<2> may be covered with leather, fibre or like material. A trimming tool (not shown) may be mounted on the base of the machine and operated by the handle l<4> and the spring l<7>. The hoppers m contain liquid colouring matter which is fed under air pressure through flexible tubes to the nozzles m<2>. The handle n raises the nozzles m<2> through the rod n<5> and simultaneously shuts off or turns on the supply of colouring material. Reference has been directed by the Comptroller to Specification 336,104, [Class 87 (i), Bricks &c.].

Title: New cellulose derivatives and their manufacture
IPC: C08B15/06
Filed: 1929-12-23
Abstract: Nitrogen-containing cellulose derivatives are produced by treating with organic bases, cellulosic material such as regenerated celluloses, incompletely etherified celluloses, celluloses incompletely esterified with carboxylic groups which are not saponified by the treatment, or celluloses which are incompletely or completely esterified with aliphatic acidyl groups.  In the latter case, the first action of the base is to saponify the ester groupings.  Suitable organic bases mentioned are primary and secondary alkylamines and the organic ammonium bases, such as methylamine, dimethylamine, ethylamine, diethylamine, tetramethylammonium iodide, methyltriethylammonium iodide; methylaniline and the hetercyclic bases are also referred to.  The starting material may be subjected to a pretreatment with acids or alkalies, wood pulps being preferably treated by the process of Specification 249,173, [Class 2 (ii), Cellulose &c.]. The invention may be applied to cellulosic material in the form of yarn or fabric, the effect being to impart thereto an affinity for acid wool dyestuffs.  In an example, the cellulosic material is heated in an autoclave with a concentrated solution of mono- or di-methylamine or ethylamine.  Specification 344,480 also is referred to.

Title: Improvements in or relating to magnetic core stores
IPC: G11C11/06
Filed: 1966-09-09
Abstract: 1,088,737. Magnetic matrix circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 9, 1966 [Oct. 5, 1965], No. 40359/66. Heading H3B. The row and column drive currents are derived solely from transformers, the secondary windings of which are connected to the drive lines by way of electronic switches. As shown, column lines are connected to transistor switches 100, 101, 150, 151 by way of diodes 102, 125, 152, 153, and to corresponding transistor switches (not shown) in circuits 90, 91. Each drive line extends from a circuit 90 to a circuit 91 and passes through two columns of cores in opposite directions. For writing, transistor switches 100, 150 are selected by coincident energization of transistors 116, 108 and 161, 160 while for reading, transistor switches 101, 151 are selected by energizing transistors 139, 108 and 162, 160. Since switches 100, 150 or 101, 151 are not under load when switched on the switching is rapid. About 25 nanoseconds after selection drive circuit 43 or 53 is energized for writing or reading and current is induced in the secondary winding of transformer 20 or 22 to flow through the selected switches and drive line. The row drive line circuitry is similar (Fig. 2c, not shown), except that the row drive lines thread only a single row of cores, and the transistor switches are again selected 25 nanoseconds before the drive circuit is energized. The row and column lines thread two cores in common but the drive currents are additive in only one core. To select the other core of the pair the read and write functions of the transformers and switches of the column circuit are reversed. The row and column drive currents are terminated by switching off the drive circuit 43 or 53 about 25 nanoseconds before de-energizing the transistor switches. Diodes 45, 55 in series with the transformer secondaries reverse bias, while diodes 46, 56 forward bias to complete the circuit for the fall of current in the drive lines. It is stated that a single transformer may be provided for both reading and writing, instead of separate transformers 20, 22, or a single transformer may provide both column and row read and write currents. The transformers or transformer must be capable of supplying bipolar pulses. In the embodiment described the cores of the matrix are divided into groups and a common inhibit-sense line arrangement is provided, two lines being supplied in parallel from an inhibit driver and being sensed differentially by a sense amplifier.
