Abstract: 1464281 Combustion of industrial waste L & C STEINMULLER GmbH 22 Jan 1974 [23 Jan 1973 13 Dec 1973] 02873/74 Heading F4B A process for the combustion of industrial waste in which waste in containers is delivered to a combustion plant where the containers are provided with outlet openings and compressed to discharge liquid or paste-like waste which is then deep-frozen and passed through a crusher to be reduced to a prescribed grain. Solid waste remaining in the containers and the containers themselves are also size-reduced and together with the crushed frozen waste are fed into the combustion chamber of the combustion plant. Air to the combustion plant is regulated in accordance with the admission rate of the waste so that the waste is burned up completely. In the process the contents of the containers may be exposed and the solid residue waste size reduced in an inert atmosphere. The solid waste may also be cooled after size reduction and mixed with the liquid or paste-like waste that is already frozen before being fed to the combustion chamber. The frozen waste from different containers may be mixed together before feeding to the combustion chamber. Reference is made to Specification 1,457,471 and Specification 1,464,282.

Automatic calculating apparatus comprises a set of electric conductors arranged on a surface to form a family of curves representing one or more relations involving one or more variables, a further set of conductors individually connected to the first mentioned conductors, a first contact capable of being moved by first driving means over the surface, a second contact capable of being moved by second driving means over the further set of conductors according to one or more relations involving one or more variables to be introduced into the calculation, a follow up circuit including one of the driving means which is energised by current supplied via the two sets of conductors for controlling the relative movement of the contacts. The described problem is to find the angle α subtended by a given line at a given point (x.y) spaced conductors 1a-1n represent arcs of circles having a common chord; a screw 3 carries a carriage 2 having a slider 6 in slideway 5 moved by a screw 7 rotated by screw 9 via gears 8, the slider 6 having a contact 11 which explores the conductors by the action of screws 3, 7, 9. Parallel extensions 12a-12n of conductors 1a-1n are traversed by a slider 13 on screw 14, the screws 9, 3, 14 being driven by reversible electric motors 10, 4, 15, respectively. The slider 13 has a contact 16 and two brushes 17, 18, Fig. 4, extending axially of the slider to contact at least one conductor in front of, and behind the conductor contacted by contact 16. Brushes 17, 18 are connected to the positive and negative poles, respectively, of a source 19 and motor 15 is connected to the neutral part of source 19 and to contact 11. In operation, screws 9, 3 represent x, y co-ordinates respectively and screw 14, having non-linear pitch represents α. With contacts 11, 16 on same conductor 12b, then movement of contact 11 across another conductor (to point x, y), closes a circuit for motor 15 through brush 17 or 18 and contact 11, the motor is driven to move slider 13 to a position corresponding to that of slider 6; the rotation of the motor shaft giving a representation of α. The slider 13 may engage a potentiometer to vary e.g. a resistance as a function of α. In a reversible apparatus. Fig. 5, not shown, the slider 6 is made similar to slider 13 and by use of a three position switch α can be determined as above, or either co-ordinate may be read as a function of α and the other co-ordinate.

Title: Improvements in or relating to pit props
IPC: E21D15/38
Filed: 1949-02-02
Abstract: 682,384. Mine props. WETZELS, H. J. Feb. 2, 1949 [Feb. 3, 1948], No. 2918/49. Class 20(ii) In a pit prop comprising an upper inner member sliding in a lower outer member, and a locking device including a wedging element adapted to be frictionally carried down with the inner prop member to increase the locking force, the number of frictionally engaged pairs of surfaces tending to cause such movement of the wedging element is greater than the number of frictionally engaged pairs of surfaces opposing the movement: The wedging element may be a plain wedge, a cam or eccentric, or a tumbler. In Fig 1 the wedge 5 is carried down by friction between'the wedge and one part 12 of a two-part upper prop-member and by a plate 6, coupled to the wedge by arms 8, subject to frictional forces from both parts 2, 12 of the upper member. The locking device also includes a transverse or setting wedge 4. A modification, Figs. 4-6 (not shown), is also described in which the prop parts and wedge are of channel section and the plate 6 is replaced by a hollow member shaped to fit in the channels of the two upper prop parts. In Fig. 7 the wedge 5 is dispensed with, the part 26 between the parts 32, 32<SP>1</SP> of the upper prop member being itself a wedge. Fig. 8 is simliar to Fig. 1 with the wedge 5 replaced by a shoe 34 and tumbler 35. In all embodiments stops, (7, Fig. 1; 27, Fig. 7; 37, Fig. 8), are provided which come up against a fixed part of the prop after a predetermined movement of the' wedging element to limit the force created by the element. The prop can then support, without further movement of the upper prop member, an increasing load up to that sufficient to force down the upper member against the frictional forces created by the wedging element and/or by the member between the two parts of the upper prop member, and by the contacting surfaces of the upper prop member and the locking device. After this yield point a further increase in load can be obtained by making the upper prop member slightly tapered. The wedge and/or the member coupled thereto in the embodiments of Figs. 1 and 4 may be of aluminium to obtain increased friction. The Specification as open to inspection under Sect. 91, also describes a prop, Fig. 1 (Cancelled), in which a wedge 5, carried down with the single part upper prop member 2 as the prop yields, is coupled to the member 2 by a strap 6. The strap 6 assists the frictional force carrying the wedge downwards and is eventually uncoupled from the member 2 by striking the top edge 3a of the locking device 3. The part 2 is tapered slightly. This subjectmatter does not appear in the Specification as accepted.

Filed: 1942-03-10
Abstract: 556,738. Coating surfaces ; insulators; resistances ; transformers; condensers. WHITE, J. March 10 1942, No. 3116. [Class 95] [Also in Groups XXXV and XXXVI] A method of forming a protective coating on an article comprises coating the article with a polyvinyl acetate resin or with a polyglyceryl phthalate resin, heating the coating to a temperature of about 180‹C., and thereafter slowly raising the coating to a higher temperature of 250‹ to 320‹C., so that the coating attains this temperature without becoming blistered, and maintaining said coating at said higher temperature for a sufficient time to cause the coating to become hard without being appreciably carbonized. The method may be used for the coating of electrical insulators, for the sealing of electrical condensers, for the coating of transformer laminations, and in the making of electrical resistances where a thin wire is wound upon a support, or a thin coating, e.g. of carbon, is applied to the support and the whole is covered by a protective coating. Resistances so coated are stabilized by the baking process. Specifications 506,117 and 548,560 are referred to

IPC: B23K1/16
Filed: 1923-02-06
Abstract: 215,432. Marks, E. C. R., (Motor Proditcts Corporation). Feb. 6, 1923. Tubes.-In a continuous process of making soldered seamed tubes for radiators &c. from strip metal, the strip is formed into a tube, the end closed, and the tube then passed through a solder bath. The strip may be formed progressively into a tube having a longitudinal interlocked seam. A metal strip A is first fed through bending rolls B - - B<3> and dies C - - C<2> for forming the strip into a U-section with hooked edges and closing them about a mandrel, then through seam closing rolls E, and then through rolls F, one of which has a cam projection for closing the forward end of the tube so as to avoid the entrance of solden into the tube. The tube is then passed through fluxing pads G, G' and then through a perforated curved tubular guide H in a solder bath. The tube is, heated by the solder so as to retain sufficient solder to seal the seam. Surplus solder is then scraped off by a die, the tube cooled by a water spray K, straightened by rolls M and automatically cut into predetermined lengths by a severing mechanism L. Power increments are applied at intervals so that the tube is drawn as well as pushed through the machine so as to place the tube under tension and thereby avoid buckling or clogging. This may be effected by progressively increasing the surface speeds of the rolls.
