Abstract: 1,250,352. Digital transmission signal. SVENSKA HANDELSBANKEN. 18 Nov., 1968 [23 Nov., 1967; 15 May 1968], No. 54537/68. Heading H4P.  A data transmission system transmitting order-address and information-characters between a master unit and one or more groups of subordinated terminal units has a modulator and a demodulator at the master unit and at each group serially interconnected to form a loop, the modulator of the master unit feeding the demodulator of the first group, the modulator of the first group feeding the demodulator of the second group etc. and the modulator of the final group feeding the demodulator of the master unit the demodulator and modulator of each group being connected by a loop in which are serially connected a group of terminal units. A data terminal or computer 1 feeds a modulator 2a with a signal A which is transmitted around the loop containing demodulators 13a, 14a, 15a, 16a, 2b and modulators 13b, 14b, 15b, 16b to achieve and maintain synchronism in the units. Each group contains units 5, 7, 9, 11 coupled to a loop connecting the demodulators and modulator of each group by a switch 3 shown in more detail in Fig. 3. Normally the switch is such that a control circuit 26 enables AND gate 22 to pass data via OR gate 25 around the loop. A signal B follows the A signal to cause each unit having data to transmit to enable AND gate 23 and inhibit AND gate 22. The next succeeding character is checked and if it is a C character AND gate 24 is enabled to cause the unit to transmit data round the loop. When the unit has sent all its data it transmits B and C characters to enable the next unit. When the master unit 1 receives the B and C characters, all units will have transmitted their data and the master unit transmits a D character if the data has been received correctly. If the data was incorrect characters B and C are transmitted to cause retransmission of data. If data is to be received by the groups characters D and X are transmitted with X indicating the address of the unit to receive the data. In an alternative circuit AND gate 24 is eliminated  and the unit transmits its data via register 17. In the event of a fault switches 28a, 28b can be used to by-pass the switch.

Title: Furnaces for manufacturing ceramically bonded bodies of expanded clay
Inventor: WUNNING J
IPC: F27B15/00
Filed: 1971-11-30
Abstract: 1356682 Furnace for expanded clay bodies J AICHELIN 30 Nov 1971 [30 Nov 1970] 55615/71 Headings F4B and F4K A furnace for expanding and ceramically bonding clay granulate material 3 comprises a chamber 2 having a tray 4 for supporting a pile of clay granulate material 3, a heat accumulator 11 on each side of the tray, a combustion chamber 6 formed between each heat accumulator 11 and the tray, and means for moving a volume of gas to-and-fro in opposite directions through the chamber 2. The means for moving the gas may be a unidirectional fan 15 and reversing valve 16 or a reciprocating piston arrangement. With the reversing valve 16 set as in Fig. 1 relatively cool gas is blown by the fan 15 into the top of the chamber 2 and down through the upper heat accumulator 11 whereby it is heated to, for example, 1200‹ C. The gas then passes through the material 3 and is cooled by giving up heat thereto. The gas temperature is then increased to a suitable value by the combustion of fuel from conduit 7 in the lower combustion chamber 6 before the gas passes through the lower heat accumulator 11, heating the accumulator and itself becoming cool. Gas coolers 12 may be provided to cool the gas further before it is drawn into the fan 15. Flow direction is periodically reversed by means of valve 16. An exhaust duct 17 is provided adjacent the fan 15 to remove excess gas volume created by combustion of fuel. In an alternative arrangement combustion air is introduced into the gas flow outside the chamber 2 and fuel is introduced into the upstream combustion chamber. Because of the low oxygen concentration of the gas entering the upstream combustion chamber combustion of the fuel is not spontaneous but is delayed until the fuel/gas mixture passes through the material 3, the catalytic action of which initiates combustion.

Abstract: 1,213,125. Counters; indicating counter readings. UNITED GAS INDUSTRIES Ltd. 14 Dec., 1967 [16 Dec., 1966], No. 56403/66. Headings G4D and G4H. [Also in Division H1] An attachment for a meter enabling the value on the meter to be read at a remote point comprises a plurality of switches each of which forms a digit wheel driven from the meter mechanism and has a number of positions, there being a number of conductors connecting the switch contacts to the remote point and enabling the settings of the separate switches to be indicated. The digit wheel 1, Fig. 1, has driving teeth 8 on one side and a single transfer tooth 9 on the other. Wiper contacts 3 and 4 are carried on a bridge 2 located by pegs 5 and 6. The wheel coacts with contacts on a printed circuit board 11, Fig. 2, having ten contacts 13 and a contact ring 16. The contact ring is energized through connection 17 to cause the value of the wheel to be read out. The boards 11 are assembled on a base having openings to receive the fingers 14 and printed connections between the corresponding outputs of the several switches. There is a separate input to each switch leading to the uppermost finger. The circuits are completed by soldering when the boards 11 are assembled on the base. The wheels are advanced at the carry position by pinions mounted on an auxiliary spindle to engage teeth 8 having a toothed portion to be engaged and rotated by transfer tooth 9 of the adjacent wheel as it passes from 9 to 0. The switching wheels may be preceded by a mechanism, Fig. 5, which actuates the wheels with a snap action. The meter rotates a worm 46 revolving a pinion 33 carrying a cam 34. The cam bears on a pin 38 on lever 36 which is loaded by spring 45. When the pin slips off the nose of the cam the lever flies clockwise and pawl 41 engages ratchet 31 to advance the wheel 81 by one digit step. Pin 39 on lever 36 engages the teeth of stop gear 30 to prevent over-running and ratchet 40 prevents backward movement. The worm actuating mechanism 100 may be operated by pulses from the meter. The wheel 81 carries an advance tooth to transmit its movement to the lowest decade wheel. The indicating wheels may be directly coupled to a socketed driving shaft on the meter body. The wheel assembly is mounted in a separate housing. Instead of having ten leads for the outputs of the successive decode wheels, the ten switch contacts may be connected together by resistors so that a signal is transmitted indicating by its amplitude the value of the wheel. The resistors may be printed or deposited on the boards 11.
