Title: Apparatus for continuous mining
IPC: E21C27/26
Filed: 1949-08-19
Abstract: 681,365. Mining-machines. JOY MANUFACTURING CO. Aug. 19, 1949 [Sept. 2, 1948; July 5, 1949], Nos. 21651/49 and 21652/49. Classes 68(i) and 85 [Also in Group XXX] In a mining-machine in which a vein disintegrating mechanism is mounted on a mobile carriage so as to have a horizontal turning movement and a radial movement in a lateral plane in respect to a vertical axis, a rearward moving conveyer and a loading scoop are associated with the disintegrating means to move laterally therewith. The loading scoop, which can be rotated about a horizontal axis, clears the floor and directs the cleanings either into the path of the disintegrating means to be carried upwards and rearwards thereby to be delivered on to the conveyer, or the cleanings may be delivered directly to said conveyer which is so designed that, no matter at what radial position it is with respect to the vertical axis, the disintegrated material is always delivered at this axis. Three embodiments of the machine are described. In two embodiments the front portion of the conveyer, in which the scraper bars are flexibly connected by chains, extends downwards beneath the disintegrating means and moves radially in step with said disintegrating means, and in one of these embodiments, io permit of this motion and. to maintain the chain at a suitable tension, the chain on the lower return run passes about a fixed idler sprocket 151 and thence upwards over an idler sprocket 154 before running forwards along telescopic troughing to the front idler sprocket 142. The sprocket 154 is carried by a shaft 156 rotatably supported in carriages which slide in slots 158 formed in the troughing and which are mounted on the piston rods 160 of piston-cylinder assemblies 161, 167 carried on a frame 163 extending through slots 164 in the conveyer troughing. The cylinders are connected by a closed circuit to a cylinder 220 the piston of which is secured to the front conveyer trunking and the proportions of the cylinders are such that the same movement in the longitudinal direction of the rear conveyer is given to the shaft 156 as to the front part of the conveyer during the radial movement thereof. To make small adjustments of the shaft 156 during lateral motion of the front portion of the conveyer, the frame 163 is adjusted longitudinally of the troughing by an arm 212 carrying a roller 211 that runs over a cam surface 210 formed on that part of the troughing which rotates about a vertical axis. In the second embodiment it is the rear idler sprocket which is longitudinally adjustable instead of an intermediate sprocket. The third embodiment is the same as that described in Specification 681,364. Specifications 660,207, [Group XXX], and 674,714 also are referred to.

Abstract: 655,691. Glass. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG. Aug. 17, 1948, No. 21692. Convention date, Feb. 5, 1942. Drawings to Specification. [Class 56] [Also in Group XLa] In the making of an airtight joint between the component parts of glass vessels, e.g. electronic tubes or glass bricks, by means of a glass "solder" melting at a temperature lower than the softening points' of the glass parts, the solder is first fused on to the glass parts and the glass parts are brought together after they have been reheated sufficiently to re-melt the " solder " whereupon the vessel is evacuated, the external pressure holding the parts together during the sealing operation. In the case of electronic tubes the electrode system is not mounted until after the " solder " has been initially fused on to the component glass parts. The " solder " may consists of 3 per cent SiO 2 , 84 per cent PbO, 13 per cent B 2 O 3  (melting point about 420‹C); ZnO, P 2 O 5 . As 2 O 3 , or Sb 2 O 3  may be added to reduce the coefficient of thermal expansion. This " solder may be pulverised and suspended in a medium, e.g. alcohol, and the suspension applied by dipping or spraying; after evaporation of the alcohol the residual glass powder is fused on.

Title: Processes and apparatus for producing stretch yarns
IPC: D02G1/10
Filed: 1956-07-16
Abstract: A drawn, thermoplastic e.g. nylon, polyacrylonitrile, polyethylene glycol-terephthalate, cellulose triacetate, mono- or multi-filament yarn "having a high degree of molecular orientation" is crimped to form a "non-torque" stretch yarn by subjection to successive treatments (which may be continuous) of hot stretching (3-20%) beyond its elastic limit at a temperature and tension such as to provide the yarn with maximum modulus of elasticity and minimum characteristic elongation to break and passing in an acutely angular path about a sharp edge at a temperature which may not be allowed to fall below the temperature at which the yarn was stretched.  The tension e.g. more than one gram per denier, under which the yarn is stretched may exceed the tension e.g. less than one gram per denier, under which it is passed around the edge; the former tension may be effected by a tension regulator or a positive feeding mechanism.  The edge may be provided by a blade, one or both faces of which are contacted by yarn approaching or leaving the edge.  Heating means may comprise a strip, plate or tube which the yarn traverses and/or contacts.  The yarn may be lubricated, as with mineral or vegetable oils or esters of fatty acids such as sorbitol tripalmitate applied by capillary or wick feed, at a point immediately preceding its contact with the edge. Examples detail optimum conditions of elongation, temperature, tension, radius of curvature of the edge and the angle of approach and departure of the yarn therewith and yarn velocity, and in relation to the nature and denier of the yarn.  Specification 558,297 is referred to.

Abstract: 1,114,594. Digital to analogue converters. GENERAL PRECISION Inc. 25 May, 1965 [25 May, 1964], No. 22253/65. Heading G4H. The lesser significant bits of a multi-bit word, e.g. the bits 01 of the word 1001, are fed to a " turn on " counter 16 (Fig. 3), which is then counted up to its maximum, that is 11, when it enables an output channel A to deliver a fixed output voltage during the remaining time intervals of the cycle of length 4t, in this case the fourth time interval t. The channel A continues to deliver an output until a " turn-off subtractor," which subtracts one from the more significant bits 1, 0 in each subsequent cycle of length 4t, gives out a "borrow" signal which switches a flip-flop 40 and so cuts off the voltage to output channel A. The output from the channel is thus a pulse of length proportional to the multi-bit word fed in. In the form shown, the apparatus simultaneously processes a plurality of multi-bit words fed into an input register 10. During the first cycle the lesser significant bits of the first word are used to switch on the output channel A whilst the lesser significant bits of the remaining words are circulated via the channel 17. During the second cycle, when the lesser significant bits of the second word are processed to control the switching on of channel B, the most significant bits of the first word are fed to the subtractor 20 where one is subtracted from them before they are recirculated. In the third cycle the process is repeated with one being subtracted from the most significant bits of the second word as well as the first word, the flip-flop 40 being connected in turn to each of the output channels A, B, C, D as the most significant bits of the first, second, third and fourth words are processed.
