Title: An improved process for covering rigid walls with facing plates made of resistant hard material
IPC: E04F13/14
Filed: 1932-09-15
Abstract: 406,069. Securing tiles &c. to walls. FISCHER, H. BORSARI-, and WELTI, E. BORSARI-, (trading as BORSARI & CO.), Zollikon, Zurich, Switzerland. Sept. 15, 1932, No. 25712. [Class 20 (iv).] Facing plates, for example of glass, for lining walls, particularly of ferro - concrete vats, are secured to the wall by mortar and are pointed with a bituminous material. The crevices between the plates are deepened and undercut by raking-out, and are filled with heated rods or strips of the bituminous material. The latter may comprise bitumen, asphalt, or pitch, with an inert filler such as tale powder, asbestos meal &c. The strips or rods are heated to the point of fusion before use and, when set, are waterproof, slightly elastic, and solid at normal temperatures. If desired, the strips may be heated in the presence of steam or water and then dry-heated before use, to render them tasteless and odourless. Preferably, the glass &c. plates are given a backing of bituminous material sprinkled with sand, before they are secured to the wall by mortar. Such backing will bond with the bituminous pointing strips. Specifications 13116/94, 22053/95, 2825/98, [all in Class 20], and 239,414, [Class 20 (iv)], are referred to.

Title: Improvements in or relating to pebble heater apparatus
Inventor: GOINS ROBERT RALPH
IPC: F28C3/14
Filed: 1950-10-23
Abstract: Pebble-heating chambers furnishing heat for the treatment of gases which are passed in direct contact through catalytic or other hot pebbles are provided with means for regulating the pebble flow through the chamber to equalize the pebble-gas contact time. According to the invention, a shell or chamber 11 lined with refractory material 12 is designed to promote the flow of pebbles from inlet 13 to outlet 19, without causing a central conical cavity, by providing an imperforate baffle 22 over the pebble outlet, the baffle being situated between inverted cones representing the angles of pebble-repose and pebble- <PICT:0688421/III/1> <PICT:0688421/III/2> slip which have their common apex at the pebble outlet.  Further, the diameter of the baffle is between 1/4 and 5/8 that of the pebble chamber and its outer periphery is situated inside and at least eight pebble diameters from the cone of pebble-repose and outside the cone of pebble-slip.  In the form shown in Fig. 1, the apparatus comprises a vertically-disposed closed shell 11 having an upper pebble-inlet zone with a perforated baffle 15 and conduit 16, an intermediate heat-exchange zone above a perforated pebble-supporting dome 17, and a lower zone 25 fed from a combustion gas inlet 24.  The gas after heating the pebbles passes to an outlet 14.  Disposed above a pebble-outlet conduit 19 extending through the centre of the dome is an imperforate baffle 22 supported above the dome by open bars 23 at such a distance that the baffle is within the inverted cone of pebble-repose (inclined at 30 degrees to 45 degrees to the horizontal plane) and outside the inverted cone of pebble-slip (inclined at 60 degrees to 75 degrees to the horizontal plane).  The vertical walls of the pebble chamber 11 are lined with common refractory material such as fire brick and superrefractory material such as silicon carbide, mullite, or alumina to withstand temperatures of 3000 DEG F. The pebbles from 1/8 to 1 inch in diameter are formed of solid refractory material such as silicon carbide, alumina, periclase, beryllia, stellite zirconia and mullite and they may either be inert or catalytic.  Two or more chambers 11, Fig. 3, may be superposed, an elevator 27 being provided for raising the pebbles from the outlet of the lowest to the inlet of the highest chamber.  In the lower chamber 11 the pebbles may contact with gaseous reactant materials and furnish heat for the treatment or conversion of the gases.  In a modification, Fig. 6 (not shown), the flow of pebbles through the centre of the chamber is prevented by a hollow core supported by the imperforate baffle 22.  In a further modification Fig. 7, (not shown), the perforate dome 17 is omitted, the imperforate baffle 22 being situated adjacent the gas chamber at the base of the shell.  The pebble-inlet in this case comprises a pipe with branches spread outwardly in place of the perforated conical baffle.  Specification 688,422, [Group XII], is referred to.

Abstract: 959,806. Telegraph pulse-shaping. SIEMENS & HALSKE A.G. July 18, 1961 [July 19 1960], No. 25993/61. Heading H4P. The centre of each telegraph pulse is sampled by pulses which are produced continuously and are supplied to a counter which, after receiving a specific number of pulses, marks a first means, which in turn on the next occurrence of stop polarity marks a second means, and the whole arrangement is restored to its initial state on the next occurrence of start polarity. Normally T3 conducts and holds cores K1, K3 in one state. On arrival of a start pulse at terminal E, T2 conducts and T3 is cut-off so that K1, K3 return to their remanence conditions. 1 kc/s. clock pulses at E<SP>1</SP> are used to product two antiphase trains α, #. The first # pulse after the start pulse resets K1 (winding 1) after which T7 conducts to reset cores K9, K10, K8, K13, K14, K16, K12. Cores K9, K10 divide train α by two, and K11 is switched between magnetic states by the α, # trains and provides input pulses to K12 which is magnetized in steps. After each fifth pulse applied to K12, T13 produces a pulse which resets K12 and is also supplied to divide-by-two circuit K13, K14. Pulses occurring at 10, 30, 50 ... m/sec. and at 20, 40, 60 ... m/sec. appear respectively on leads A<SP>1</SP>, B<SP>1</SP>. Cores K15, K16 make up the counter with a capacity of seven. After 130 m/sec., K16 is fully reversed, T16 conducts and K5, K6 are set if stop polarity is being received. K6 is reset one m/sec. later by the next A pulse on winding 2, and applies a pulse to K7, K11, the latter thus reducing the system cycle by 2 m/sec. The B<SP>1</SP> pulse occurring at 138 m/sec. resets K7 which in turn sets K2 representing the second marking means. The cycle is then repeated after the next pulse of start polarity arrives at E. The sampling pulses A<SP>1</SP> are applied to windings 2 of cores K3, K4, one or other of these cores providing an output pulse according to the polarity of the input at E.
