Abstract: 464,641. Moulding and wrapping explosives &c. by rolling-machines. IMPERIAL CHEMICAL INDUSTRIES, Ltd. (African Explosive & Industries, Ltd.) Oct. 21, 1935, No. 29043. [Class 87 (ii)] [Also in Group XVII] Cylinders of plastic material such as blasting explosive are formed to a predetermined length and diameter and preferably also wrapped by extruding a length, rolling the length to the required diameter between a drum and co-operating rollers, cutting it to the required length by cutters mounted on or near the periphery of the drum, and discharging the formed cylinder. The material is extruded from a nozzle 15 onto a shelf 17 and is severed by knives 2, 3 on the rotating drum 1 which co-operate with the nozzle 15 and a fixed knife 18 respectively. The severed length drops into a gap 10 in the drum and is carried forward to a stop or stops 12, situated in grooves 13, 14, and is thus raised into operative position between the periphery of the drum 1 and the rollers 8, 9. After the cylinder 23a has been rolled out by the rollers it is cut to the required length by knives 4, 5 fixed to the drum. A sheet of wrapping paper 22 is cut by rolls 20 to the required size, fed between the drum and the cylinder 23a and is wrapped round the same by the stop 12 and rolls 8, 9. The projecting portions of the wrapping paper are then crimped by members 6, 7 on the drum and finally folded by tampers 25, 26 which are operated by a cam 27, mounted on the shaft of the drum 1, and a projection 28 on the lever 29. The wrapped cylinder finally falls into the gap 11 and is discharged by gravity. Specifications 423,871, [Group VIII], and 446,286 are referred to.

Title: Curing of green briquettes
IPC: C10B53/08
Filed: 1965-07-08
Abstract: Green briquettes made of calcined char derived from coal and a bituminous binder are cured in a continuous (partial combustion) process at 400 DEG  to 550 DEG  F. (204 DEG  to 288 DEG  C.) by being passed downwardly through a reactor in countercurrent to an air stream which contains particulate heat transfer solids, e.g. calcined char, sand or other minerals.  The solids are recycled through a cooling device, and the flow rates of the solids and of the briquettes are controlled to ensure at least 10% by volume oxygen (on a solids free basis) in the top of the reactor where the hot briquettes enter.  The temperature difference between the inlet and exit ends of the reactor should not exceed 60 DEG  F. (in a specific example the inlet temperature was 430 DEG  F., the outlet 400 DEG F.), and preferred residence times in the reactor are 1 to 2 hours. The cooling device for the solids may employ direct cooling by air or water, or indirect cooling.  The cured briquettes may be subsequently coked.

Title: Improvements in or relating to electric circuit arrangements for varying the brightness of electric lamps
IPC: H05B41/392
Filed: 1950-11-29
Abstract: 726,654. Control systems for lamps. GENERAL ELECTRIC CO., Ltd., and WILLIAMS, C. E. Nov. 28, 1951 [Nov. 29, 1950], No. 29251/50. Class 38 (4). [Also in Group XXXIX] An electric circuit arrangement for operating and dimming one or more lamps, particularly, but not exclusively, low-pressure discharge lamps, 55 ... 57, comprises a transformer 4 whose primary winding 3 is connected in series with the A.C. winding 62 of a regulating transductor 61 to A.C. supply terminals 1, 2, and connections from the primary winding or a secondary winding 10 of the transformer 4 to supply operating current to the lamp(s), said connections including, in series with the lamp(s), the A.C. winding(s) of one or more dimming transductors 58 . . . 60 and rectifying means 16 which, responsive to the flow of lamp-operating current, feeds D.C. through the D.C. winding 78 of the regulating transductor 61; this arrangement is such that, e.g., when the dimming transductors 58 ... 60 are operated to increase the lamp current, the increased D.C. output from the rectifier 16 decreases, due to core saturation, the impedance of regulating transductor A.C. winding 62, whereby to increase the voltage across the transformer 4 and hence that across the lamp-operating circuit, thereby increasing the effectiveness of the dimming transductors. As shown, the lamp electrodes 69 ... 74 are supplied with heating current by secondary windings 63 ... 68 associated with the regulating transductor A.C. winding 62 whereby increasing lamp current results in decreasing output from such secondary windings. In other embodiments, the electrode heating windings are wound on the main transformer 4, or on a separate transformer whose primary winding is made lamp current responsive by a separate transductor, or on a separate transductor which is itself similarly responsive. The invention is also applicable to a plurality of series-connected lamps.

Title: Improvements in the construction of models representing molecular and other structures
Inventor: KENNARD OLGA
IPC: G09B23/26
Filed: 1962-07-30
Abstract: 1,034,391. Making wirework; welding; soldering. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 25, 1963 [July 30, 1962], No. 29263/62. Headings B3A and B3R. [Also in Division G5] A model comprising wire or tubular elements 6 joined to represent a molecular structure, architectural design &c., is constructed by holding the elements in their correct relative positions during the joining, e.g. welding or soldering, by clamping means secured magnetically to a base 1. In one arrangement, Fig. 1, a sheet of drawing paper showing the positions in plan of the points representing atom centres is secured to a base plate 1 of iron or steel. Ring magnets 2 are placed on the sheet over the indicated positions. Each magnet 2 is fitted with a vertical tubular holder 3 in which slides a pointer rod 4 which is adjusted until its tip indicates the vertical co-ordinate of an atom centre. A pair of wire elements 6 cut to the correct lengths and which represent valence bonds is now assembled so that adjacent ends of the elements abut at the tips of the rods 4. For this purpose universally-adjustable clamps such as 10, 14 are employed each carried by a block 7 resting on the base 1. When the wires are correctly assembled, the blocks 7 are magnetized, to lock them in position, by a switch or a plunger 8 according to whether they are electrically or magnetically operated. Alternatively, the base 1 may be magnetized. The parts 2 . . . 4 are now removed and the ends of the wires connected, e.g. by soldering. This operation is repeated until the entire framework has been constructed. To complete the model, spheres representing the atoms and moulded from a suitable plastics material such as cold setting polyurethane, are cut into parts which are subsequently re-united by adhesive around the frame-work. In a modified arrangement, the wires 6 are assembled using tabulated bond lengths angle data, and for this purpose a set of plate-like transparent members 22, Fig. 2 (not shown), are employed. The angles between the sides of the members range from 60 to 135 degrees, and each member has grooves along at least two of its sides to accommodate a wire 6. When correctly set by means of the plates, clamps such as 10, 14 are used to hold them whilst they are joined. A pendant clinometer 32, Fig. 3 (not shown), can be used to set a third wire in correct angular position relative to two wires already joined. To assist in the assembly, beams of light normal to the base 1 may be employed, so that a shadow of a wire 6 is projected on to the plan on the base and the wire can be moved until its shadow coincides with the corresponding part of the plan. A molecular model may be made in two parts, a tubular element being attached to the end of a terminal valence bond of one part to receive a terminal valence bond of the other part; in this way the rotation of parts of the molecule may be demonstrated.

Title: Improvements in or relating to printing telegraph receivers
IPC: H04L17/16
Filed: 1945-11-06
Abstract: 601,355. Printing telegraph receivers. CREED & CO., Ltd., and SALMON, R. D. Nov. 6, 1945, No. 29526. [Class 40 (iii)] A device for incorporation in a printing - telegraph receiver to adjust the timing of selector members with respect to the received impulses and which includes a cam released by the start element of a signal and operating to effect the connection of the selector member to a driving shaft by means of a ratchet clutch is described in its application to the telegraph receiver set forth in Specification 228,842, [Class 40 (iii)]. The cam 10 which is driven from the driving shaft by a friction clutch, is held in its stop position by the engagement of a lug 11 with one arm 13 of a pivoted detent lever 14 having a second arm 16 associated with a spring-biassed retaining lever 17 which assumes the position shown when the cam 10 is in the stop position. A latch member 20 which is held under a spring blade 27 secured to the arm 16 is moved to the right by pivoted levers 22, 24 when a lever 25 is actuated by the armature 26 of the receiving magnet in response to the start element of the signal. Lever 17 is rotated against the action of a spring 18 and the detent lever 14 rotates counter-clockwise under the action of a spring 19 to release the disc 10. Towards the end of a revolution, a roller 29 carried by the arm 16 is engaged by a second lug 12 and the lever 14 is rotated clockwise so that its end is again engaged by the lever 17. If the latch member 20 is in its right-hand position when the lever 16 is rotated, the end portion engages the top of the lever 17, the spring blade 27 being deflected. When the armature is moved to the left in response to the stop element of the signal, the end of the latch 20 drops into its normal position on the arm 16. Shortly after the commencement of the rotation of the cam 10, the lug 12 engages a roller 30, Fig. 4, mounted on the same shaft as a second roller engaging the inner curved surface of a lever 39 fixed on a shaft 40 carrying a lever 42, Fig. 7, operating a detent 44 which on release allows the pawls 7 to clutch the selector member 2 to the driving shaft. The roller 30 which is adjustable in a path concentric with the disc 10 is carried by an arm 31 pivoted in a frame 32 which is adjustably secured to a fixed arcuate frame member 33. The frame 32 carries an index mark for association with a scale on the frame 33, Fig. 5 (not shown). Specification 487,291 also is referred to.
