Title: Electrical arrangement for analysing sums of money and the like according to species
IPC: H03M7/02
Filed: 1957-03-20
Abstract: 822,761. Digital electric calculating-apparatus. BRUNSVIGA MASCHINENWERKE A.G. March 20, 1957 [April 13, 1956], No. 9135/57. Class 106 (1). An electrical arrangement for analysing sums of money comprises selective circuits, switching relays, and counting mechanisms for each specie of currency. In a first embodiment for counting German specie a four-pole ten-way switch 11 can be set in any of ten positions 0-9 to represent a single-digit multiple of pfennigs, marks, or tens of marks. As there are " 1," " 2 " and " 5 "-unit species in each of these orders, counters 26, 27 and 28, respectively, are provided to count up these coins and/or notes. In switch position " 8," for example, circuits are completed for relays 20, 21 and 22 which, in turn, close switches 23, 24 and 25 to complete the circuits of the counters 26, 27 and 28 respectively. If " 9 " is set up on the switch 11 the relays 21 and 22 are energized to operate counters 27 and 28, and the change-over contacts 30 are transferred to cause the charging of a condenser 29. When the relays 21 and 22 are subsequently de-energized the contacts 30 return to connect the charged condenser to a further relay 31 which is now energized to close contacts 32 and operate the counter 27 a second time, thus registering the correct equivalent on the counters 27 and 28. In the range of ten to ninety pfennigs no twenty-pfennig specie exists and therefore in a further arrangement (Fig. 2- not shown) only two countersfor 10 and 50 pfennig pieces, respectively, are provided. In this case three storage condensers are provided which may be discharged in succession to operate the 10-pfennig counter up to four times in registering one amount (40 pfennigs or 90 pfennigs).

Title: Improvements relating to electric signalling systems for railways
IPC: B61L1/10
Filed: 1944-05-12
Abstract: 577,405. Apparatus for detecting passage of rail wheels along a track. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. N. May 12, 1944, No. 9154. [Class 105] The passage of a railway wheel along a track rail is detected by an arrangement of two inductances at least one of which has its characteristics modified by the presence of a wheel whereby either such inductance is brought into balance with the other inductance so that an associated relay energized when the inductances are out of balance (as by an inductance-bridge arrangement) becomes de-energized, or the modification of the flux from one inductance (energized by oscillating current) which in its normal distribution causes an e.m.f. in the other inductance, which other inductance in this case is situated at the same side of the track rail, is such that an e.m.f. is no longer induced in the said other inductance whereby a relay controlled from said other inductance becomes de-energized. As shown an inductance A is energized by oscillating current of audio frequency from an oscillator OSC and acts on an inductance B which has its axis arranged at right angles with its mid point offset from the axis of inductance A. The flux from inductance A being asymmetric relative to inductance B causes an e.m.f. in the latter which is applied to the control grid of a valve V1. The grid has a negative bias but the positive half-waves of applied voltage give a pulsating anode current which, amplified if necessary by a valve V<2>, energizes a transformer OT feeding an axle-counting relay TRA through a rectifier bridge MP. The anode circuits may include tuning condensers. Two such arrangements may be provided immediately adjacent to give a directional counting, for example a second inductance C and associated relay TRB may be provided for the other end of the energized inductance A. The two arrangements may be associated with the opposite rails of the track to avoid operation by stray iron such as a tool. One arrangement for the balancing inductance form of apparatus comprises a split transformer primary having the two inductances inserted in the split primary half-circuits and acting in opposition. Normally the inductances are unbalanced and an e.m.f. is induced in the secondary winding but the presence of a wheel brings the inductances into balance and thereby prevents an e.m.f. being induced in the secondary winding. Energizing current may be switched on only when a train is approaching.

Title: Process for separating alkyl-substituted benzenes from hydrocarbon mixtures containing the same
IPC: C07C7/152
Filed: 1953-04-07
Abstract: An alkylbenzene containing more than two alkyl substituents is separated from a hydrocarbon mixture as herein defined by extracting at a temperature not above atmospheric with an extraction agent comprising a compound of aluminium chloride or bromide with an alkylbenzene so chosen that said compound is at least as stable as the most stable compound which can be formed between any compound of the said mixture and the aluminium halide. The hydrocarbon mixture contains higher alkylbenzene(s), i.e. containing more than two alkyl substituents, with one or more mono- and/or dialkylbenzenes.  It may contain saturated hydrocarbons but substantially no unsaturated aliphatic hydrocarbons should be present.  The stability of compounds of aluminium chloride and alkylbenzenes increases in the sequence: mono-alkyl, p-dialkyl, o-dialkyl, m-dialkyl, 1,2,4- and 1,2,3-trialkyl, 1,2,4,5- and 1,2,3,4-tetra-alkyl, 1,3,5-trialkyl, 1,2,3,5-tetraalkyl, penta-alkyl, hexa-alkyl.  Thus extraction of durene from a mixture containing also o-diethylbenzene may be effected with a compound of aluminium chloride and durene or mesitylene.  If more than one higher alkylbenzene is present, that which is higher in the stability sequence is preferentially extracted.  By selecting the quantity of extraction agent, however, one or more other alkylbenzenes may also be extracted. The process is operated in analogous manner to that of Specification 732,476.

Abstract: 707,744. Drying furnace linings. BLANCHARD, P. April 24, 1951 [May 5, 1950], No. 9547/51. Class 34(2) The refractory lining of a furnace is dried by heating the inside and outside of the furnace simultaneously, a stream of gas, the temperature of which rises progressively being circulated within the lining and a stream of gas at constant temperature being circulated around the outside of the lining during the greater part of the operation. The furnace and lining 14 is placed in a drier 15 in communication with a furnace having a gas or oil burner 2 and fan 3 blowing air to the burner controlled by a baffle 4 operated by a regulator 5 influenced by a pyrometer rod 6 in the furnace 14. Hot gases escape to the upper part of furnace 14 and are diluted by air or gases supplied by fan 3 through duct 16 and after passing around the outside of furnace 14 escape through duct 17 and are used to dilute other hot gases from the burner. At the beginning of the drying the temperature inside furnace 14 is limited to about 100‹C and is retained outside the furnace 14 at 90‹C by cold air admitted by baffle 10 operated by a pyrometer 8 and regulator 9. By adjusting regulator 5 the temperature is allowed to increase slowly to complete the drying. In a modification a jacket is built around a fixed furnace instead of placing the furnace in a chamber.

Filed: 1948-04-06
Abstract: 651,011. Telephone transmission. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 6, 1948, No. 9635. Convention date, April 22, 1947. [Class 40 (iv)] [Also in Group XL (c)] When modulating a carrier with a wide signal band extending almost to zero frequency, it is difficult to select a single side-band to the exclusion of the other side-band. The invention provides a system of modulating and filtering in successive stages, allowing the desired separation to be effected with ordinary filters. The signal band a modulates a carrier of frequency f<SP>1</SP> producing the side-bands b, Fig. 2. Incomplete suppression of one sideband, shown at c in dotted lines as the upper side-band is effected by a filter A and the residue modulates a frequency f<SP>2</SP>, lying on the same side of f as the partially-suppressed side-band. Of the two widely-separated sidebands d, the upper is completely suppressed by a filter C and the lower has the unwanted portion suppressed by a filter B whose lower pass limit is f<SP>2</SP>-f<SP>1</SP>. The filters B, C can be combined in a single filter. The output e is the original signal band stepped up in frequency an amount f<SP>2</SP>-f<SP>1</SP>, and this may be modulated on a frequency f<SP>3</SP> (which may be the same as f<SP>2</SP>) to give the side-bands f. On account of the gap between these bands, either may be readily separated by a filter D to give the final band g.
