Title: Process for the continuous production of metallic magnesium by thermal reduction
IPC: D01B3/08
Filed: 1935-07-27
Abstract: In the continuous production of metallic magnesium by the thermal reduction of magnesiferous raw materials, such as dolomite, with the aid of silicon or ferrosilicon at temperatures substantially below the melting point of the reaction residue, followed by condensation of the magnesium vapour, up to 5 per cent of an alkaline or alkaline-earth fluoride or mixture of two or more of such compounds are added to the reaction mixture.  The fluoride &c. may be added in the form of dry salts or a solution, the mixture in the latter case being preferably briquetted and the solvent removed, preferably as completely as possible, by drying. Specification 413,606, is referred to.  The Specification as open to inspection under Sect. 91 states that up to 10 per cent of the fluoride may be used, and that chlorides of the same metals may be used instead of, or in addition to, the fluorides.  This subject-matter does not appear in the Specification as accepted.

Abstract: 723,753. Centrifugal spinning and twisting apparatus. PRINCE-SMITH & STELLS, Ltd. July 20, 1953 [Aug. 26, 1952], No. 21433/52. Class 120 (2). The end of a yarn mass withir a container of a centrifugal spin ning or twisting machine is re. covered after s spinning break and while the con tainer is rotating and the yarn is wound on to a bobbin by restrict. ing the reciproca. tion of the yarr guide and feeding into the guide a length of thread until its end portion is laid upon the yarn mass sc that, when a bob, bin is introduced into the container, the bobbin en. gages the thread between the guide and the yarn mass. A yarn guide 3 is normally reciprocated over the axial length of the interior of a container 1 by a bracket 4 on a rail 5 guided by lifter spindles 7 suspended from chains 15 attached to chain pulleys, such as 14. The chain pulleys 14 are mounted on a sleeve 13 freely journalled on a rock shaft 12 oscillated by a builder motion to bring about reciprocation of the guide 3. The sleeve 13 is driven in one sense only by a lost motion drive that comprises a collar 16 adjustably carried by the shaft 12 and having a pin 17 that in one direction of oscillation engages a pin 18 carried by a chain pulley 14. Secured to the sleeve 13 is a collar carrying a pin that is adapted to be held by a latch operated by a pedal 25 through a rod 19. Depression of the pedal 25 causes the sleeve 13 to be held against rotation for at least the greater part of its arc of movement so as to cause the yarn guide 3 to be temporarily stopped in an elevated position and its further reciprocation to be confined to a small portion of the axial length of the container. With the yarn guide so arranged, a span of thread may be inserted in the guide to initiate winding onto the bobbin.

Abstract: 1,208,033. Mixing gases. S. HORROCKS. 9 May, 1969 [9 May, 1968], No. 21979/68. Heading B1C. [Also in Divisions F4] In a method of mixing high temperature combustion product gas with a lower temperature gas containing solid particles, the high temperature gas is injected transversely into a duct along which the low temperature gas passes, there being no baffles in the duct in the mixing zone which could become radiant emitters and on which solid particles might fall and melt. As shown in Fig. 3 the duct 11 is surrounded by a combustion chamber 14 of annular cross-section which is supplied with fuel and air through tangential ducts as a mixture or separtely (see Figs. 4 and 5, not shown). Combustion takes place at one end of the chamber 14 and the gases swirl round it so that combustion is complete by the time the hot gases reach the other end where they are injected radially into the duct 11 through apertures 15. Flame is confined to the chamber 14 and the emerging high temperature gases confine the low temperature gas 3 to the axial region of duct 11 so that solid particles therein are not deposited in the hot walls of the duct in the mixing zone 12; the duct is also without baffles. The hot gases may be utilized in a drier (1) or other apparatus, and part recycled with fresh low temperature gas (see Fig. 6, not shown), or passed to a heat exchanger (20) to pre-heat incoming low-temperature gas (see Fig. 7, not shown).

Title: Card width sensing device
IPC: G06K21/08
Filed: 1958-07-10
Abstract: 836,504. 'Checking dimensions of record cards. CUMMINS-CHICAGO CORPORATION. July 10, 1958 [July 10, 1957], No. 22233/58. Class 106 (1). [Also in Groups XXXVI and XL (b)] In a machine adapted to sort out worn or under-size cards the cards are fed in turn through a measuring station consisting of a group of detectors 51, 52, Fig. 3, on each side to co-operate with the edges of the card, means for coupling together corresponding ones from each group to form pairs, each pair being spaced apart a distance differing slightly from the standard width of a card, and a circuit responding to simultaneous actuation of both detectors of a pair to indicate the presence of a substandard card. In the form of Fig. 3, the detectors 51, 52 are formed of a stack of conducting strips 61-70 and 81-90, Fig. 6, insulated one from the other and adjustable in position by bolts 72, 73. Corresponding strips of each group are connected by cable 96. Brushes 53, 54 bear down on the upper faces of the strips and make contact with any not covered by the card 50. Detecting under-sized cards.-In the form of Fig. 6 the pairs of detectors are spaced apart a distance slightly less than the standard card width so that a sub-standard width card allows the brushes to contact a coupled pair of strips, as shown in Fig. 6, to complete the circuit through relay 100, Fig. 3. A deflector controlled by the relay deflects sub-standard cards to a reject pocket. In high-speed operation a timing device is included to operate the deflector at the proper time. The brushes are energised only when the length of card is in the central position under the brushes, blade spring contact switches 110 disposed on either side of the detector position in the path of feed of the: card serving to short out the supply at other times. Photocell detectors.-In the form of Figs. 7 and 8 the paired detectors are light-conducting rods 96a in U-form, light from a lamp 53a being applied at one end and picked up by a photocell 54a at the other end if the card is narrow enough to expose both ends of any rod. Series connected card lever contacts allow the control circuit to be operated by the photo-cell only when the length of card is centrally disposed with respect to the detectors. The detectors also respond to notched or ragged edges to cards, a pulse stretcher being employed if necessary to increase the sensitivity. Detection of over-sized cards.-If the groups of detectors are paired so that each pair is spaced apart a distance slightly greater than the width of the card, a circuit will be completed when a normal card is present and no circuit when an over-width card is present. A relay energized by a normal card is effective to prevent operation of the deflector whereas an over-size card is deflected to the reject pocket. Groups of detectors for detecting both under and oversized cards may be provided. Specifications 812,753 and 830,590 are referred to.
