Title: Solid fuel boilers
Inventor: AXMACHER MAX
IPC: F23N1/02
Filed: 1965-04-13
Abstract: 1,097,686. Solid fuel boilers. KOKSINSTITUTET. April 13, 1965, No. 15783/65. Heading F4W. A solid fuel boiler 2 for domestic water heating comprises a bottom discharge fuel container 4 of greater volume than a firebox 5 which has a door 11 and a plane shaking grate formed of a central section 12 and two lateral sections 13 separated below by partitions 16, situated over a withdrawable ash box 14 containing partitions 17 corresponding to said partitions (16), Fig. 3 (not shown). Combustion air entry is controlled by a damper 18, which has a flap 20 mounted thereon connected to a draught control 21 sensitive to the boiler water temperature in order to control the air to the central grate portion 12, while an automatic ash remover driven by a servomotor (24), connected by a shaft (25) to eccentrics (27), (28) abutting against spring-loaded rods (29), (30) connected to grate portion 12, 13 respectively acts to shake only that grate portion supplied with air. When the demand on the boiler is low, damper 18 is closed and only grate section 12 is supplied with air and simultaneously shaken. On increasing the demand, flap 20 opens to its limit 22 thereupon opening damper 18 to supply air to grate section 13, when a resilient arm 31 actuates a switch (32) to reverse the servomotor switch (23) and hence actuates eccentric (28) which is mounted on a slipping clutch (not shown) so that it operates only when shaft (25) rotates in one direction. The fire spreads to the whole grate which is now shaken completely to remove ash. The firebox flue 7 may contain radiation plates to promote heat transfer from the waste gases passing to chimney 8, while the draught control may be replaced by a room thermostat with servomotor.

Title: Improvements relating to null methods of electrical measurement
IPC: G01R17/10
Filed: 1949-06-14
Abstract: 675,969. Bridge circuits. HOLZER, D. M. DE, [Representative of HOLZER, R. C. DE]. Sept. 14, 1950 [June 14, 1949], No. 15861/49. Class 37. A bridge circuit has in one arm the resistance 1, Fig. 1, to be measured and in another arm a set of resistances 5 calibrated in one hundred steps in series with a second set of resistances 6 calibrated in one hundred steps, each equal to one hundredth part of those in the set 5, the galvanometer 15 being calibrated to read one hundred divisions for each one step of the second set 6 and having a switch 14 by which its sensitivity can be reduced to one hundredth or one ten thousandth of that indicated by the calibration. Resistances 2, 4 are of 50 ohms and resistances 3, 7 are of 100 ohms each. The variable resistance 5 comprises one bank 8, Fig. 2, of nine elements 10 of 1 ohm, each in series with a step switch 11. This bank is in series with a similar bank 9 having each element of 10 ohms resistance, so that the whole element 5 gives a range of from 0 to 99 ohms in steps of 1 ohm. The other variable resistance 6 is of the same construction as the unit 5 except that all the resistance values are one hundredth part of those in the unit 5 so that for each step of the resistance 5 a subdivision of 100 steps is provided by the unit 6. The instrument 15 is so calibrated that with the switch 14 short-circuiting both resistances 16, 17 the reading is the amount by which the resistance 1 exceeds the value of the resistances 5, 6, full scale reading corresponding to one step of the bank 8 of the unit 6, i.e. 0.01 ohm. If the resistance 17 alone is in series with the instrument 15 the sensitivity is reduced to <SP>1</SP>/ 100 th part of that of the instrument alone, while if both resistances 16, 17 are in series, the sensitivity is reduced to 1/ 10000 th part. Alternatively the sensitivity may be reduced by connecting the supply terminals 12 of the bridge to a potentiometer across the supply voltage. A thyratron may be arranged to permit current to pass from the bridge to the instrument 15 only when the voltage across the related diagonal of the bridge is not more than that equivalent to full scale reading of the instrument.

Title: Signal conversion system
IPC: H04N1/415
Filed: 1974-04-10
Abstract: 1471419 Data transmission; facsimile systems KOKUSAI DENSHIN DENWA KK 10 April 1974 [12 April 1973 25 July 1973] 15868/74 Heading H4P A method of reducing the number of bits transmitted, particularly in a facsimile system, comprises forming incoming bits into blocks and transmitting those having significant information, but run length encoding bits of like type into blocks of preferably similar or alternatively dissimilar length, flag bits being added to distinguish each type of block. When run length encoding leaves gaps in transmission, these may be filled with information from another source. A digital signal on terminal 101 is sampled at 2, the result being clocked into a 6 stage shift register 3 by pulses from generator 1 which are simultaneously counted in a scale of 6 counter 5 which at each reset enables detector 6 to examine the bits stored in register 3 and the last bit stored in succeeding register 4. If signal changes are detected AND gate G is opened, content of 3 is transferred to 4, and flag register F is set to 1; the latter is detected by 9 hence content of register 4 is transferred to memory 10 and transmitted together with a 0 marker bit. With no signal changes a counter 7 increments, which is recorded in 8 until a subsequent transition is detected when flag bit 8-F is set to 1 which is again detected by 9 hence content of register 8 plus a 1 marker bit is transmitted through memory 10. If counter 7 fills then content is transmitted as one block, e.g. of six or less bits and a new cycle commenced with subsequent blocks until a transition is detected. At the receiver a circuit (203) identifies marker bits and activates one of two gates (204, 205) the latter passing an incoming block into a counter (206) which is decremented for each shift pulse to correspond with a number of identical bits counted at the transmitter, these being placed in a shift register (209) which alternatively may receive through gate (204) blocks containing significant information.

Title: A method for the removal of carbonic oxide from combustible gases or mixtures of combustible gases containing organic sulphur compounds by a contact process with steam catalysis
IPC: C10K3/04
Filed: 1938-05-27
Abstract: 507,120. Gas - purifying processes. BRANDT, R. May 27, 1938, No. 15890. Addition to 490,920. [Class 55 (ii)] The method of removing carbon monoxide from combustible gases, such as coal or coke .oven gas, according to the parent Specification is modified by adding to the initial gas part of the main gas after its subjection to the steam catalysis, so as to allow for the variation of combustible gas produced, in the coke ovens for example. This enables the steam to gas ratio contacting with the catalysts to be kept more easily constant and the converter plant to be uniformly loaded. The addition is particularly necessary during charging and discharging of the ovens. The added gas may be freed of carbon dioxide before admixture and may be added to the initial gas before the latter is purified from hydrogen sulphide. An additional catalyst, differing from the two catalysts of the process of the parent Specification, may be interposed between them or arranged between the two layers of the main catalyst, in order to obtain a refining of benzol hydrocarbons in combustible gasÚs containing them in addition to carbon monoxide. For this purpose, catalysts known for the hydrogenation of tar and oil vapours may be used; molybdenum oxide deposited on active carbon, silica gel, &c. is specified.
