Title: Process and apparatus for charging and compressing loosely charged coal within oven chambers
IPC: C10B37/04
Filed: 1932-01-22
Abstract: 386,129. Coke ovens; charging- apparatus. STILL, C., Recklinghausen, Westphalia, Germany. Jan. 22, 1932, No. 2032. Convention date, Jan. 26, 1931. [Classes 51 (ii) and 55 (i).] Apparatus for charging coke ovens through a row of openings in the roof, and for compressing the charge by means inserted through the roof comprises supporting means mounted on the ovens and carrying vertical worm shafts which alternate with rods which on withdrawal leaves ducts in the charge. The means for the vertical movement of the worm shafts and of the forming rods may be independent of one another. In the oven roof are charging openings 5, and gas withdrawal openings 11, which lead by a collecting pipe 13 to a gas main 15, the space above the charge communicating by a pipe 7 with an hydraulic main 9. A charging car 19 is mounted on rails 18, and carries a coal container 20 provided with hoppers 21 for each of the openings 5, the coal being supplied through a feed roller 22, which may be divided into sections for each hopper. The charge compressing means consists of vertical shafts 33 each carrying a worm 44, and capable of rotation by a motor 38 through bevel wheels 34, 36, and horizontal shafts 35, the whole being mounted on a cross girder 25, which may be raised or lowered by chains 26 wound on a drum 29 rotated by a motor 30. The duct forming means consist of vertical rods 54 suspended by chains 53 from drums 50 on a shaft 49 mounted in bearings 48 on a girder 24, and caused to rotate by a motor 51 and gearing 52. In operation, the gas mains 9, 15 are closed, and the duct forming rods 54 are lowered through the openings 11 until they rest on the bottom of the oven in the position 54<1>. The feed roller then charges coal into the oven, and the screw shafts 33 are lowered and rotated in the manner described in Specification 385,038, the coal being forced both downwards and laterally. After compression and removal of the shafts 33, the rods 54 are withdrawn by the winding drums 50, the charging car is moved away, and gas withdrawal tubes 16 inserted in the ducts 17, the openings 11 and 5 being then closed by covers. The distillates are withdrawn by suction from the ducts 17 into the main 15, and gas from above the charge passes at approximately atmospheric pressure into the main 9. The compression of the charge may be increased, prior to heating, by use of a levelling rod as described in Specification 362,783, and any particles of coal blocking the ducts 17 may be cleared by lowering the rods 54 again into the ducts. In a modification the duct forming rods and the compressing worms are mounted on the same cross girder and operated together.

Title: Improvements in processes for the treatment of peat, distiller's wash or the like material
IPC: C10F5/00
Filed: 1920-01-22
Abstract: 162,738. Goldschmidt, R. B., and Migeon, M. Jan. 22, 1920. Manures.-By exposure to the air the water percentage of peat is brought to about 60, when the peat is placed in silos, treated with beetroot or molasses wash and allowed to ferment. During the process of fermentation the peat loses a great deal of its contained water, the amount of which is further reduced by compression. The product thus obtained may be used as a manure.

Title: Improvements in or relating to transistor sawtooth wave generators
Inventor: PARKYN DEREK JOHN
IPC: H03K4/54
Filed: 1962-01-22
Abstract: 975,836. Transistor saw-tooth wave-generating circuits. MARCONI CO. Ltd. Oct. 18, 1962 [Jan. 22, 1962], No. 2223/62. Heading H3T. A saw-tooth wave-generator comprises a first transistor of predetermined conductivity type, connected as the active element of a blocking oscillator and including a base blocking condenser, and a second transistor of opposite conductivity type which is included in the current discharge path of the condenser and arranged to cause the discharge of the condenser to take place at constant current. As shown, in Fig. 1, a blocking oscillator comprising PNP transistor TR1 with its collector and base electrodes coupled by transformer T has a base blocking capacitor K connected as shown to the collector of NPN transistor TR2 such that the discharge of the capacitor will be at constant current and the output sawtooth wave at terminal O/P will be linear. The slope of the saw-tooth may be adjusted by means of variable resistor R2 and better linearity may be obtained by inserting a further resistor (not shown) in the emitter lead of transistor TR2. In the circuit of Fig. 2 the generator is synchronized by differentiating negative going locking pulses by network DC, feeding the resultant pulses to the base of transistor TR3 and applying the positive-going pulses produced at the collector thereof to the circuit including transistor TR1. The circuit of Fig. 1 may be modified to act as a triggered generator, Fig. 3 (not shown), by connecting a catching diode to the junction of capacitor K and the collector lead of transistor TR2 so as to prevent operation of transistor TR1 until it receives a trigger pulse. The generators may be stabilized against temperature variations, Fig. 4 (not shown), by inserting a resistor in the emitter lead of transistor TR2 and connecting the base of the latter to the slider of a potentiometer connected across the supply.

Title: Automatic combustion control devices
IPC: F23N5/20
Filed: 1973-01-18
Abstract: 1393491 Burner controllers ELESTA AG ELEKTRONIK 18 Jan 1973 [26 Jan 1972] 2631/73 Heading F4T A combustion control device has a relay R, Fig. 1, for energization by a photo-electric flame sensor 47, Fig. 4, to operate a contact bank al in a first direction, and an electrically heated bimetal spring actuator 15 which moves a member 19 transverse to said first direction to operate a contact bank tr1, Fig. 3, actuator 15 also moving a locking plate 33 engageable with an armature spring 39 of changeover contactor a1, which are for fuel flow control, to prevent operation of contacts a1 if relay R is energized during a pre-start illumination test. On closure of a thermoswitch Th a combustion air motor M, an ignition device ZT and the heater TR of bimetal spring actuator 15 are energized. Spring 15 heats up to release plate 33 from spring 39 and to change over contacts tr1 by means of a snap spring 21. A fuel valve V1, Fig. 4, is thus opened and, following ignition and flame sensing, relay R is energized to move contacts a1, a2 from the position in Fig. 4 thereby deenergizing heater TR, but maintaining igniter ZT and valve V1 energized over contacts a1 and tr1, the igniter being de-energized when contacts tr1 resume their initial position (as in Fig. 4) on cooling of spring 15. In this position contacts tr1 may energize a second fuel valve V2 via contacts a1. If the flame fails relay R is deenergized whereby all the contacts are in the start position and a new start-up cycle is initiated. If sensor 47 on start up senses too high an ambient illumination relay R is energized but contacts a1 are prevented from changing over by locking plate 33, even when spring 15 heats up, thus continuing energization of heater TR and preventing fuel flow. Spring 15 can then heat up sufficiently to cause a part 23, Fig. 3, on a compensating spring 17 to engage one end of a slot 51 of a member 25 to thereby cause member 25 to allow operation of shut-down contacts tr2 to de-energize the controller and operate a signal lamp LP. A manual reset device 9 is provided for contacts tr2. Bimetal actuator 15 operates in the same way to cause shut-down if ignition is not effected within a predetermined time.

Filed: 1968-01-18
Abstract: 1,198,891. Photo-copying apparatus. HENRY SIMON Ltd. Jan.18, 1968 [Jan.27, 1967] No.2774/68. Heading G2A. [Also in Division B3] Apparatus for reproducing an original with selectively changed dimensions in one direction forms part of a machine for drilling holes (see Division B3) in part cylindrical plywood shells which are then used in rotary die cutting. A selected two of the original, the copy sheet and the light source are moved at predetermined linear speeds while the third remains substantially stationary to give the dimension change. One edge of an original, e.g. a tracing 192, Fig.36 is releasably stuck to a bar 62 of a compensator assembly 44 Fig.2 and drawn thereby past a narrow slot 156 illuminated by a light in the assembly 48. Photo-sensitive material 188 secured to a plywood shell 185 and carried by a cylinder 100 is also moved past the slot 156 at a different linear speed to obtain an image having its dimensions in one direction changed relative to the original. The compensator assembly is drawn across a table top 55 by means of spaced belts 83 attached to a bar 63 of the assembly, which belts pass round tracks 103 of the cylinder 100. The cylinder and belts are driven by the same motor. The speed differential of the original is obtained by altering the position of a setting bar 90 to vary the speed with which the bars 62-64 draw up. If desired, the speed differential can be varied for different parts of the same original.

Title: Improvements in or relating to telecommunication systems
IPC: H04B3/20
Filed: 1930-01-29
Abstract: 347,687. Two-way repeaters. VIARD, G., 254, Rue de Vaugirard, Paris. Jan. 29, 1930, No. 3083. Convention date, Feb. 15, 1929. [Class 40 (iv).] A uni-directional amplifier, employed in a twoway repeater, is arranged to amplify the speech transmitted in either direction, the connections to the amplifier, which has a bias in one direction, being reversed when necessary by the transmission over the circuit of a frequency outside the normal speech range. The amplifiers 3, Fig. 1, are normally connected to transmit in the direction 1-2. When transmission in the opposite direction takes place the speech currents pass into delay network 6 and also energize relay 10 which connects to the circuit a current of frequency outside the normal transmission range. This current is amplified by amplifiers 7 which are tuned to this frequency only and energizes slow-acting relay 4 which reverses the connections to amplifiers 3 and enable them to amplify the currents in the direction 2-1. The control frequency is rejected by the band-pass filters 5, 5<1>. To prevent the operation of relay 10 by current flowing in direction 1-2 the device 9 may be arranged either to reject all frequencies passed by the filter 5<1> or the arrangement shown in Fig. 3 may be used. Currents flowing from 2-1 energize relay 14 whilst those flowing from 1-2 energize relay 13, the operation of 13 by currents from 2-1 being prevented by the delay device 6 which enables 14 to pull up before the operating currents have passed through the delay network.
