Title: An electric heating system for embedment in cast concrete and plaster structures
IPC: F24D13/02
Filed: 1959-03-17
Abstract: 915,782. Electric heating grids. WILLIAMS, C. I. March 17, 1959 [March 21, 1958], No. 9169/59. Class 39 (3). [Also in Group X] Elongated reinforcing members embedded side-by-side in structures of cast concrete or plaster are connected by members 22 and couplings 23 also embedded in the cast material to form a grid through which heating current is passed. The reinforcing members are straight or crimped steel rods, or (as shown) expanded steel meshes 21<SP>1</SP> brazed to steel channel members 181, and may be sprayed with an alkalineproof lacquer or coated with a silicone insulating material by spraying or dipping. The members 22 may be of steel and the couplings 23 may be of non-ferrous material, e.g. copper or brass, or may be of ferrous material, in which case jumpers of copper cable are connected across them to prevent the formation of hot spots. Concrete slabs with the combined reinforcing and heating arrangement may be used in the construction of buildings, airplane runways and roads. If the slabs are laidon the ground, a layer of heat-reflecting material, e.g. felted paper covered with aluminium foil, is interposed. Two grids with the elongated reinforcing members mutually at right-angles may be superimposed in one floor structure and separated by insulators at selected points. Grids may be connected in series/parallel to provide different degrees of heat at different parts of a floor. A building construction is described in which grids embedded in concrete floors and plaster walls are provided with thermostats and connected in groups to control panels provided with timing devices for off-peak storage heating.

A centrifugal separator, for separating an air stream containing waste products into a relatively small portion containing a high percentage of waste products and a relatively large portion containing a low percentage of waste products, comprises a tubular bend member 12, Fig. 1 of rectangular or square cross-section extending over 45‹-180‹ and having at one end a bifurcating member 15 widening in the direction of the air stream and carrying at its outlet end a separating partition 17 for portioning off the air stream. The bend member 12 is connected to a spiral-shaped delivery channel 9 of a centrifugal pump for sucking off, with the aid of air as transparent medium, waste products from around wood working machines in a work room in order to separate these products from the air. Mounted upstream of the partition 17 is a member 22 fixed on a spindle 23 which is pivotably actuated by means outside the member 15 for adjusting the portioning off of the air stream. Due to centrifugal force the coarse products get separated against the outer wall of the members 12 and 15 and leave with 5-25% of the air stream through an outlet pipe 20 which is connected to a cyclone separator from which the air is discharged to the atmosphere and the coarse products are carried off to a wood waste room. The light products leave with the bulk of the air through a discharge pipe 21 which is connected to a filter from which the air is returned as clean air to the work room. In a modification, Fig. 2, the discharge channel 25 of the centrifugal pump may be of circular cross-section and may be connected via a connection portion 27 to-the bend 12a. The latter is integral with the bifurcating member 15a which in turn is integral with the partition member 17a and the discharge pipes 20a, 21a. In a further modification, the bend and bifcurcating member assembly and the pump 1 may be in different planes.

Title: Improvements in or relating to machines for use in forming heel seats on boot and shoe soles
IPC: A43D8/48
Filed: 1926-04-14
Abstract: 274,543. Gimson Shoe Machinery Co., Ltd., Bagshaw, C. M., and Wardle. W. April 14, 1926. Bevelling and splitting machines; traversing- cutter machines.-In a machine of the kind described in Specification 271,535, for forming shouldered heel seats on shoe soles, the marginal portion of the sole is yieldingly held against movement while its central part is being forced through a form plate and while the marginal portion is finally severed. The shouldering is effected by severing cutters moving in the plane of the sole and in opposite directions, and means are provided whereby the shouldering may be made to extend the full width of the sole. The form plate carries knives for severing stitches which may prevent the heel end of the sole being properly positioned in the machine. The form plate 8 has a U-shaped opening for supporting the rear end of the sole, the upper marginal portions 9 of which are tapered. The sole deforming plunger 60 has a stem 61 which is surrounded by a sleeve 64 provided at its lower end with presser feet 66, 68 with lower faces parallel to the taper 9. A collar on the stem 61 engages the upper end of a spring which normally depresses the presser feet to hold yieldingly the sole margin. Knives 80 are adjustably carried by the form plate to sever stitches too near the heel end of the sole. The plunger 60 is depressed by a treadle linked to rocking levers 15, 19. The skiving-knife 26 may be operated by hand or power. In the latter case, a driven pulley 85 is connected to a shaft 84 by a friction clutch. Normally, the shaft is prevented from turning by a tooth at the end of a hand lever 90. When this tooth is released, the shaft makes one revolution, and an eccentric 92 operates a rocking lever 95 linked to the knife 26, which thus performs the skiving cut and returns. Shouldering-cutters 50 are moved inwardly from opposite sides of the sole, these being operated by handles 45. The extent of the shoulder so formed is determined by a stop 22 on the lever 15, which can be so adjusted that the whole width of the sole is in the path of the shouldering- knives when the treadle operating the plunger 60 is fully depressed.
