Abstract: 665,690. Distilling carbonaceous solids. PITTSBURGH CONSOLIDATION COAL CO. April 25, 1949 [May 15, 1948], No. 10889/49. Class 55 (i). Carbonaceous solids, e.g. coal, lignite, oil shale, are distilled by contact with reheated distillation residue of which a portion has been burnt to yield a hot flue gas serving to heat the remainder which alone is returned to the retort. A rotary retort 10 as described in Specification 665,681 is charged with coal from a hopper 12 and previously distilled material through a screw feeder 15 at a rate and temperature such that residue picked up by lifters 20 and discharged through a screw feeder 24 still contains volatile components. Vapours separated from the residue pass to a condenser 32 and solids in part to storage and the rest to a conduit 46 to which flue gas from a combustion zone 65 is introduced. The residue at 1400‹ F. or more passes through a separator 48 whence a portion is returned to the retort, flue gas and evolved volatiles being conducted to a second separator 56. The remainder of the residue from the separators is fed through a conduit 64 to the combustion conduit 65, air being admitted through a pipe 74. The flue gas obtained may be circulated in indirect heat exchange with the residue which may be conveyed by only a portion or by a readily movable gas such as superheated steam or carbon dioxide. A retort temperature of 800-1400‹ F. for the low temperature distillation of high volatile bituminous coal is obtained by adjustment of the amount and temperature of the residue returned to the retort.

Title: Improvements in hot water heating installations
IPC: F24D3/02
Filed: 1925-04-28
Abstract: 232,994. Pamart, L. E. April 28, 1925. Heating buildings. -Water is circulated through a heating system in pulsations by means of steam produced in the auxiliary boiler supplied intermittently with water. The boiler comprises a water space a and coil b. The space a is connected by pipes d, e to an expansion space c, and the coil b is connected by a pipe o to a " pulsator " g. Another pulsator f is connected to the pulsator g by a pipe! i, and to the pipe e through a non-return valve h. The pipe e and coil b are connected by a pipe k. Water is supplied to the radiators through a pipe r having a valve s which allows the passage of water in the direction of the arrow, but not of steam. When the apparatus is full of water to the level AB, steam is generated in the coil band passes into the upper end of the vessel g, forcing the water through the pipe r to the radiators and back through the pipe t to the chamber c. When the water in vessel g uncovers the pipe u, steam passes into the vessel f and forces some water into the vessel g, which condenses the steam. The reduced pressure draws water from the chamber c through valve h to refill the vessels f, g, and also coil b so that the cycle is repeated. In a modification, the coil b may be fed from the vessel g, and in another modification, Fig. 3, the supply and discharge of steam to and from the vessel g are controlled automatically by a float valve w. When the vessel is nearly empty, the float x closes the admision of steam through the pipe o and opens the outlet through the pipe z. so that the vessel can refill through the pipe i'.

Title: Improvements in and relating to package binding
IPC: B65B13/12
Filed: 1941-09-02
Abstract: 553,788. Bundling. CHEESEMAN, J. J. Sept. 2, 1941, No. 11191. [Class 94 (i)] A machine for binding packages with metal strip or wire comprises a member for training a strip around a package, means for rotating the member around the packages always in one direction, and a series of freely-rotatable coplanar-rollers which support around, but out of contact with the package, additional strip which is drawn from the supply during the movement of the member. The additional strip accumulates on the rollers to form a stock which is separated at intervals from the main supply and applied to successive packages. The member for training the strip comprises a ring 11 which is supported on rollers 26 within an opening in a vertical frame 10 and is rotated unidirectionally by a motor 40. The parcel B to be bound is supported within the ring by a table 23. The ring is provided at intervals with laterally-projecting pins on which flanged rollers 50 are freely rotatable. One of these rollers, 50a, serves as a take-off roller for the metal strip S and may have associated with it a set of adjustable rollers 53 to apply tension to the strip as it passes around the article B. Rollers 65 are provided for applying tension to the strip as it passes from the supply to the ring. In use, the strip S is drawn from the supply over the rollers 55. 50a, and 53, and its front end is clamped in a gripper 14 on the edge of the table 23, the rollers 50a being just below the level of the table. Rotation of the ring 11 in a counterclockwise direction trains the strip around the package B. At the end of one revolution, the ring stops and the overlapping ends of the strip S are connected to one another by a suitable sealing-mechanism 16, the strip being severed after sealing. During the rotation of the ring, the strip has not only been drawn from the supply, but a length of the strip has been laid over the rollers 50. With successive rotations of the ring, a stock of the strip is built up on the rollers 50, as shown in Fig. 7, and when the rollers are full, the supply strip from the rollers 55 is severed. To maintain the coils of strip in place on the rollers, a resilient clamping band is unwound from a roller 58 and passed over the rollers 50. The binding operation is then continued on successive packages until the stock of strip accumulated on the rollers is exhausted, when the clamping band is removed and strip is again drawn off the rollers 55.

Title: Improvements relating to apparatus for marking a record by means of electric discharge or spark
Inventor: BOYLE ARCHIBALD RAYMOND
IPC: B26F1/28
Filed: 1948-04-24
Abstract: 654,310. Recording-apparatus. DOBBIE McINNES, Ltd. April 24, 1948, No. 11331. [Classes 106 (ii) and 106 (iv)]  Recording apparatus of the type wherein a spark is employed to mark a record sheet, more particularly for recording engine indicator diagrams, comprises a drum 6 which constitutes one electrode and a rod electrode 5 having a bulbous end of diameter between 0.2 and 2 millimeters. A pressure - sensitive movable piston 13 is mounted in an insulating bush 22 and breaks and makes at 11 and 12 the primary circuit of an induction coil to produce the recording spark. The piston 13 is biassed to the left by a pressure applied via conduit 14, the left-hand side of the piston is influenced by the pressure in the cylinder 24 via a conduit 15. When the cylinder pressure exceeds the predetermined applied pressure, the piston is forced to the right and causes a spark to pass and mark the sheet. The predetermined fixed pressure applied to the piston 13 is obtained from a supply source 16 via a control valve 17. A piston 18 is also moved under the influence of the predetermined pressure against a spring to position the electrode 5 across the drum 6 in accordance with the pressure set. When the cylinder pressure 24 overcomes the predetermined pressure and the piston 13 breaks the primary circuit of the spark coil, the record sheet is marked and similarly when the pressure in the cylinder 24 decreases to the point where the predetermined pressure overcomes it. Thus two points on the indicator diagram are marked by the passage of a spark at each setting of the predetermined pressure. By working over a number of engine cycles and systematically varying the setting of the valve 17 controlling the predetermined pressure, the complete indicator diagram may be recorded.
