Title: Improvements in or relating to walls, partitions or the like
IPC: E04B2/62
Filed: 1936-11-16
Abstract: 487,222. Walls ; metal framework. KING, D. M. Nov. 16, 1936, No. 31286. [Classes 20 (ii) and 20 (iv)] A wall, partition, or the like, comprises a main framework formed of a plurality of channel girders 17, one or more subsidiary frames which are constructed of angle-irons 11. and are mounted within the space defined by the members of the main framework in such a manner that they are maintained slightly apart from each other and from corresponding members of the main framework, and panels 10 which are of a size corresponding to that of the subsidiary frames and are clamped to one face of the structure formed by the main and subsidiary framework. The clamping means for the panels comprises a joint-cover plate 12, a co-operating strip 14 applied over the rearwardly-directed edges of the frame members, and bolts 13 passing through the plate 12 and strip 14 and disposed in the spaces provided between adjacent members of the built-up structure. Fig. 1 shows the bolts 13 disposed in the space between the angle-irons 11 of adjacent subsidiary frames, with the channel strip 14 applied over the edges of these angle-irons, and Fig. 3 shows bolt-receiving spaces provided between the main girder 17 and the subsidiary frames, with the strips 14 fitting over the adjacent edges of the girder 17 and angle-irons 11. The girders 17 may, as shown in Fig. 2, be constructed to form a rectangular frame, and the subsidiary frames are then also constructed of rectangular form with additional transverse stiffeners 11a, if desired. The subsidiary frames, which are spaced slightly apart and from the main girders 17, are secured together and to the girders 17 by transverse bolts 16, and these may, as shown in Fig. 1, also extend through the strips 14. The spaces provided between adjacent angle-irons 11, and between angle-irons 11 and adjacent girders 17, may be filled with a suitable packing, or, if desired, washers may be mounted between the angle-irons. If desired., the girder 17 may be set forward with respect to the angle-irons 11 in order to allow for the thickness of the panels, in which case packing material may be inserted in the space thus formed between the limb of the girder and the strips 14. The corner joint between adjacent angle-irons 11 of each subsidiary frame may be strengthened by strips welded across the joint. The subsidiary frames may be of rectangular shape as shown in Fig. 2, or of triangular or any other suitable shape.

Title: Barbecue briquettes and method of making the same
IPC: C10L5/14
Filed: 1961-08-31
Abstract: A process for making barbecue briquettes comprises drying a carbonaceous fuel, e.g. lignite, at 18, carbonizing the dried fuel at 20 to remove tar in gaseous form and a portion of the non-tar volatile matter, separating the tar from the gas leaving zone 20 and cooling the gas at 50, either recirculating the cooled gas via lines 52, 58 or bringing a cool, clean inert gas into contact with the char to cool char in a zone 22 as the char leaves the zone 20, reducing the char to fine particle size, e.g. at least minus 40 mesh, at 84, and mixing the char at 86 with a binding medium, e.g. precooked starch and water.  The zone 20 is maintained at 500 DEG  to 550 DEG C. by regulating the amount of cooled off-gas delivered through a line 60 and by regulating burners 34.  Cool inert gas may be mixed with the off-gas in all proportions and off-gas may be delivered by lines 62, 64 to burners 34, 26 respectively.  The temperature of the zone 20 is such as to ensure that the char comprises 10 to 20% by weight of non-tar volatile combustible matter.  The briquettes contain 3 to 10% by weight of binder.  In an example, lignite from the Dickinson seam, North Dakota, containing (by weight) 41% water, and on the dry basis consisting of 43% <PICT:0946358/C3/1> volatile matter and tars, 46% fixed carbon and 11% ash, was dried at 130 DEG C. and carbonized at 510 DEG  C. \sB 5 DEG  C., retaining 12 to 13% by weight non-tar volatiles.  After crushing to 60 mesh, the char was mixed with 3 to 4 parts 270 mesh starch and 12 to 15 parts water (both per 100 parts char) and pressed to form briquettes with 6% water content.

Abstract: 1,108,167. Continuous-casting processes. ERIK OLSSON A.G. 23 July, 1965 [23 July, 1964], No. 31471/65. Heading B3F. A continuously-cast strand is moved forwards by the forward movement of a longitudinallyoscillated and cooled mould 3 but is prevented from moving back with the mould by freshly solidified metal at the inlet of the mould forming between the earlier solidified metal and a nozzle 2 which projects from a feeder vessel 1 into the mould inlet. Either the mould or the strand, or both, may be vibrated to decrease sticking and improve grain structure. The strand path may be downwardly sloped to assist the forward movement and if the slope is small there may be rolls 5 or clamping jaws for moving the strand forward in steps in synchronism with the mould. If the slope is large, the rolls 5 beyond the mould exert a braking effect on the strand. The mould walls at the inlet may be inwardly curved to reduce the cross-sectional area and assist the strand movement. The strand may be cooled by water sprays or cooling jaws or by passing it through a sand bed.

Abstract: 1,132,713. Track brakes. DOWTY MINING EQUIPMENT Ltd. 20 July, 1966 [30 July, 1965], No. 32683/65. Heading F2E. A telescopic track retarder, comprising a piston 15, which is depressible in a cylinder 12 by a passing wheel of a track vehicle to pressurize an hydraulic chamber 31, and a valve 23, which has a pressure responsive valve member 25 that closes on depression of the piston when the passing vehicle exceeds a predetermined speed to prevent flow past said valve member through ports 29 and 35 to a low-pressure outlet 21 from the chamber 31, is characterized in that there is provided a two-stage relief valve comprising a pilot valve 49 which opens at a predetermined pressure and a main valve member 45 which is normally closed by the bias of fluid pressure in chamber 31 and spring 47 during contraction of the retarder but which is opened in response to flow through the pilot valve. On depression of the piston by a vehicle moving below a predetermined speed, valve member 25 remains in the open position, and hydraulic fluid is discharged from chamber 31 through ports 29, 28 and 35 to chamber 21 of two lowpressure chambers 19 and 21 formed in the piston by a second floating piston 22, chamber 19 being filled with nitrogen. Thus no appreciable retardation to the vehicle is effected. However, on depression of the piston by a vehicle moving above a predetermined speed, the pressure drop across said ports and valve member 25 is sufficient to move the said valve member to the closed position against the bias of spring 27. When subsequently the pressure differential between chambers 21 and 31 rises to a predetermined value, pilot valve 49 opens to allow continued flow through ports 52 and 53. This flow reduces the pressure acting in chamber 41 below the lower end of the main valve member 45 so that pressure acting on the annular area at the upper end moves the valve member from its seat 44. Hydraulic fluid is then discharged from chamber 31, through ports 46 and the now open valve. In a modification the housing 23 and associated valves may be mounted on the cylinder 12 for connection to an external low-pressure source. In a further embodiment, Fig. 3 (not shown), the pressureoperated valve 25 is omitted and discharge from chamber 31, on contraction of the retarder, takes place entirely through the two-stage relief valve which is secured to the fixed cylinder and which controls the discharge to a lowpressure outlet (56). A retarder having this latter construction would exert a braking action for all vehicle speeds.
