IPC: E04D3/362
Filed: 1944-03-07
Abstract: 599,793. Floors, walls, and roofs; building units. WYNMALEN, H., and POWELL, J. W. March 7, 1944, No. 4257. [Classes 20(ii), 20(iv) and 87(i)] Panels used in the construction of walls, floors, ceilings &c.. are provided with integral or attached top and bottom clips or flanges a, b so arranged that by movement of each panel in its own plane and perpendicularly to the edges carrying the clips, the said clips are engaged with clips of adjacent panels and with the flanges of joists, purlins or other structural members. Outside panels are provided on their vertical or rising edges with a lip c and a roll d so that the rolls d fit over the lips c, e.g., when the panels are used for roofing. Alternatively adjacent roofing panels may be plain overlapped, or joggled overlapped, or the side joints may be formed by flanges similar to the flanges a, b. In Fig. 6, panels t of metal, metal alloy, wood, plywood, asbestos-cement, plastic or laminated plastic, on which suitable clips a, b are attached or formed, are used for constructing cavity walls, the clips being of wood, or of metal formed in appropriate profiles, e.g., u and v at the bottom and top edges respectively of an outer panel, and wand x at the bottom and top edges of an internal panel. When the panels are to form the junctions between the walls and the roof, or to form the ridge cap or closing element of the roof lining, the panels are suitably curved. The panels s, forming the floor, may be surfaced with linoleum y, or a composition material, plywood or boards, and the ceiling panels z may have a surfacing z<1> of plywood, plaster board, fibre board, acoustic board &c. Fig. 7 shows interlocking clips a, b of modified form.

Title: Improvements in machines for making conical dishes
Filed: 1926-02-15
Abstract: 265,385. Rogers, F. H., (Vortex Mfg. Co.). Feb. 15, 1926. Pile tables and supports for sheet feeds; sheet separators; sheet-registering devices.-In a machine for making conical paper dishes, blanks are successively transferred by a continuous rotary mechanism to forming - devices which convert them into conical shape, the forming-devices operating simultaneously on different blanks and successively on the same blank. Several dish-forming units are mounted in a framing 1, Figs. 1 and 5, and driven by a main shaft 2, which is connected by a chain 4 and clutch 8 to a driving-shaft 5 on each unit, the clutch 8 being operated by a hand-lever mounted on a shaft 10 but being disengaged automatically by a throwout 14 on the shaft 5 if the machine jams. Through gears 16, 17 the shaft 5 drives a lay shaft having at one end a pinion 21 which drives the blank-feeding mechanism. the pinion 21 is connected through a shaft 23 and chain 26 to a shaft 28 geared to a shaft 32 carrying rollers 34 on which pads 35 are mounted. These pads withdraw the lowermost blank of a pile stacked between guides 39, 40 and feed it towards a table 55, the blank being guided and propelled first bv one pair of feed-rollers and then by a second pair of feed-rollers driven from the shafts of the first pair, which are driven by the shaft 32. the blank fed on to the table 55 is centred thereon so that the grippers of a rotary transfer device mav engage it in such a way as to ensure correct folding of the blank. The centring mechanism is mounted on the support of the transfer device. Above the shaft 74 is a sleeve 89 carrying the shaft 88, Fig. 8, of the rotary transfer. device and on this sleeve, between it and a stationary collar 91 is pivoted a table, 92 upon the outer end of which, in a sleeve 93, a plunger 94 is mounted. The plunger 94 carries a spider 99, Fig. 6, on which are pivoted fingers 100 provided with springs which tend to raise their outer ends and hold their inner ends against posts 102 on the table 92. A spring 103 presses the plunger 9a downwards and maintains a roller 96 secured beneath it in contact with a fixed platform 107 on the framing 1 or with a cam 106 adapted as hereafter described to raise the plunger and the spider 99 and thus permit the spring-pressed fingers 100 to rise into engagement with the blank on the table 55 and centre it thereon. The blank is taken hold of by the grippers of the transfer device as the grippers move from position B to position C, Fig. 1, the table 92 and the centring device moving with them. During this movement the roller 96, Fig. 8, on the plunger 94 rides up the cam 106, closing the fingers 100 on the blank and keeping it centred as the grippers grip it, a pawl which depends from the table 92 engaging the spindle of the roller 96 to keep it in the raised position.

[Also in Division C1] The content of alkalies, i.e. Na 2 O and K 2 O, in cement clinker is reduced and alkali-rich dusts are recovered in cement kilns operating with exhaust gas temperatures of 100-300‹C., e.g. Lepol travelling grate rotary kiln, by preheating the cement raw material by heat exchange with the hot exhaust gases, from the kiln which are withdrawn from the preheating at a point where their temperature is such that the sublimed alkalies in the gases begin to be deposited as a solid, the dust in the withdrawn gases are extracted, the dust-free gases returned to the preheating and the extracted dust is separated into an alkali-rich fraction used, e.g. as a fertilizer, and an alkali-poor fraction which is mixed with the raw material. The dusts may be separated by a wet method, e.g. by flotation in a solution saturated with alkali. Raw cement is fed via shoot 1 to travelling grate 2 and rotary kiln 5. Hot exhaust gases from 5 are fed to heating chamber 4 and through the cement on 2 to chamber 4<SP>1</SP> which contains dust collectors 6. Gases from 6 pass via trunk 7 to drying chamber 3 and through the cement on 2 to chamber 3<SP>1</SP> where fan 8 feeds a final dust separator 9. The dust collected is taken by conveyer belt 11 to be separated into the two fractions, the alkali poor fraction returning on to grate 2 via shoot 1. Specification 874,818 is referred to.

Filed: 1929-02-11
Abstract: 328,701. Croad, A. K., (Hanovia Chemical & Manufacturing Co.). Feb. 11, 1929. Coating. - The surface of copper plates for copper-oxide rectifiers is coated with oxide by heating to a high temperature in an oxidizing atmosphere and quenching by subjecting to the action of the vapour of an active substance in an inactive base. The inactive base may be paraffin and the active material hydrochinon or an alcohol. aldehyde, lietone, organic acid, or hydrocarbon. The quenching medium may be formed by adding hydrochinon crystals to liquid paraffin wax. The crystals sink to the bottom and remain solid provided the temperature is below 169‹ C. The usable bath temperature lies between 70‹ C., the melting point of paraffin wax, and 169‹ C., the melting point of hydrochinon. The copper plates are immersed in the bath when at a temperature of about 500‹ C.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 15, 1935.] Drawings to Specification. [Class 40 (iv)] In modulated carrier transmissions over adjacent circuits and using the same carrier frequency, cross-talk during silent intervals is due mainly to the carrier on the disturbed circuit picking up transmissions on adjacent circuits, and to avoid this, the carrier is suppressed at the transmitter during these intervals so that cross-talk comprises only the attenuated carrier and side-bands picked up from an adjacent circuit. Balancing of the circuits at the carrier frequency by known methods may be effected and if more than one carrier frequency is used on each circuit, the balancing condensers &c. are situated on the transmitter and receiver sides of the separating filters. Any known method of preventing the transmission of the carrier, when modulating signals are not applied, may be used. The balancers and the carrier suppressors may be adjustable for temperature variations &c. The Specification as open to inspection under Sect. 91 comprises also a system in which the carriers are suppressed even when modulated, the carrier being supplied to the receiving demodulator only when signals arrive. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 173,284, 246,808, and 308,172, [all in Class 40 (v)].
