Title: Improvements in or relating to record card
Filed: 1949-01-03
Abstract: 662,142. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. Jan. 3, 1949 [Jan. 13, 1948], No. 71/49. Class 106 (i). A sensing device for sensing a perforationreceiving position of a record card comprises two or more separately movable pins, means for moving the pins into engagement with the card, and means operative after the pins have been moved to detect whether any have passed through the card. In a first embodiment a conical tube 13, Fig. 1, contains a plurality of pins 18, held frictionally in a moulding so as to be movable longitudinally and individually. They converge at the lower end to form a compact circle of slightly spaced pins 18, Fig. 5, for sensing a perforation 20. Upon energization of a magnet 15 the pins are lowered into contact with the card, those in line with a perforation passing through. To sense whether any have passed through, a magnet 21 is energized to rock an armature lever 22 and contacts 23 which latter, if meeting a pin or pins which have passed through a perforation, close to complete an appropriate circuit. Alternatively a circuit may be completed by contact of a pin 18, Fig. 6, with a bed-plate 11a. In a second embodiment, two pins 40, Fig. 8, are employed, pivoted in a plate 41, and contacts 45 are closed if either or both pins find a hole. In both the first and second embodiments the pins are restored to their initial position by upward engagement with a stop member. In a third embodiment, three sensing pins 30, Fig. 10, in the form of pivoted levers biassed by blade-springs 32 and normally held by a bail 33, are employed. The pins are staggered in relation to the hole position.

Title: Process for the extraction of metal values from aqueous media
Inventor: SPITZER ERNST LEOPOLD THOMAS M
IPC: C01G49/10
Filed: 1967-01-02
Abstract: Metal values (i.e. compounds of metals other than alkali metals are extracted from an acidic aqueous medium containing halide ion and at least one metal value in solution or in suspension by contacting with an organic sulphide in liquid form, immiscible or only part miscible with the aqueous phase.  The sulphide is preferably used in undiluted form but may be diluted with e.g. halogenated solvents, ether, and hydrocarbons.  The sulphide preferably has two hydrocarbon chains attached to the sulphur atom.  The effective chain length (as defined) is preferably 6-16 and examples of the sulphides used are di-sec-butyl sulphide, di-n-butyl sulphide, di-isoamyl sulphide and secoctyl 2 hydroxyethyl sulphide.  The preferred halide ion is the chloride ion.  CuII may be extracted from a 3-6N HCl aqueous solution and FeIII may be extracted from a 5-10N HCl aqueous solution.  The extracted metal values can be recovered from the organic phase by treatment with water or a dilute mineral acid.  If the extraction is carried out at a controlled pH then copper (II) values can be selectively extracted from an aqueous solution which also contains iron (III) values; such a solution may be produced by leaching copper ores.

[Class 119] To damp the rate of firing of an automatic pistol or the like having an unlockable breech block, the latter is loaded by a freely-movable mass which acts by inertia to oppose the initial movement of the block in both directions. As shown, the breech-block comprises head portions 8, 10 connected by a rod 9 on which a weight 11 is slidably mounted. In the closing movement of the block under the reaction of the propelling- spring 12, the weight 11 hugs the head 10 up to the actual firing and then moves forward to strike the head 8 thereby impeding the return movement of the block. In the reverse movement, the weight 11 is thrown up to the head 10 to impede the reaction of the spring 12.

Title: Improvement in methods and apparatus for making glass structures by pressing and blowing operations
IPC: C03B9/33
Filed: 1942-01-09
Abstract: 556,582. Glass manufacture. MANTLE LAMP CO. OF AMERICA. Jan. 9, 1942, No. 355. Convention date, Jan. 13, 1941. [Class 56] A method of making a glass article, particularly an elongated article such as a lamp chimney, consists in placing a charge of molten glass in the upper part of the cavity of a parison mould, pressing the charge partly to shape by means of a plunger inserted in the mould, then blowing the charge until it fills the parison mould, and finally blowing the parison so formed in a finishing mould. The parison mould 10, Fig. 1, has a long tapering cavity 11 which is closed at its lower end by a plate 17 and has its upper part enlarged to co-operate with a ring mould 12. A plunger 13 slides through the ring mould and presses the glass until the upper portion fills the ring mould cavity and forms the open end of the parison. The bulk of the glass is forced to the position 18 which extends only part way down the cavity 11. Formation of the parison is completed, as shown in Fig. 2, by compressed air which is blown through small holes 15 in the plunger. The parison is then transferred to a finishing mould by means of the ring mould and is blown to shape in the usual way, the mould being rotated relatively to the parison to prevent the formation of mould marks. The ring mould preferably consists of a solid outer ring 12a and a sectional and expansible inner ring 12b. When the.blowing of the article is completed, the ring 12a may be lowered relatively to the ring 12b to enable the article to be removed. The method may be used for making tubular articles, or blanks 96, Fig. 12, for vacuum bottles. The Specification, as open to inspection under Sect. 91, describes also a modification in which the glass charge, when pressed, fills the whole of the mould cavity which is then increased in volume to allow for the first expansion of the charge, by lowering a plunger that forms the bottom of the mould cavity. This subjectmatter does not appear in the Specification as accepted.
