Filed: 1957-12-19
Abstract: 832,865. Electric selectors. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 19, 1957 [Dec. 29, 1956], No. 39480/57. Class 40 (4). A two-co-ordinate selector is arranged so that the first co-ordinate is selected by a combination of magnets moving appropriate code bars to free one of a number of bell-cranks controlled by each of a number of magnets, one of which is operated according to the second co-ordinate. The connection is maintained as long as the second co-ordinate magnet is energized. Opposite each second co-ordinate relay 2 is a number of spring sets 4. Energization of a combination of code magnets 15 moves the corresponding code bars 14. A bar 13 is then rocked by magnets 16. Only those bellcranks 10 which find their upper arms opposite slots in all the bars 14 can rock to the extent of engaging their lower arms with the upper edges of armatures 3. Operation then of one of the second co-ordinate magnets 2 completes the selection and operation. The connection is maintained as long as the magnet 3 is operated. The code magnets can meanwhile be used to make a further selection. Two spring sets can be operated at one cross-point, selection of one of the sets being made by a further set of two code magnets. As an alternative operation of a spring set is effected when the associated second co-ordinate magnet is released (Fig. 4, not shown).

Title: Improvements in or relating to apparatus for identifying movable objects
IPC: B61L25/04
Filed: 1964-09-29
Abstract: 1,023,902. Track apparatus. PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd. Sept. 29, 1964 [Oct. 2, 1963], No. 39615/64. Heading B7N. [Also in Division H4] In apparatus for identifying objects, e.g. rail vehicles moving past an interrogating device, wherein the responder includes a plurality of different frequency signal generators which are energized by a D.C. signal derived from an R.F. signal transmitted by the interrogator and a distributer which selectively cuts off in succession various combinations of generators to form a coded identification signal for transmission to the interrogator, means are provided for preventing operation of the distributer until a signal exceeding a predetermined level is received simultaneously at the interrogator from each responder signal generator. The interrogator, Fig. 1, includes an RF generator GR which transmits a signal via aerial TA to the passing responder aerial RA, Fig. 2, and the received signal is rectified to provide a D.C. signal -V across capacitor C 2  to energize the responder equipment. Signal generators G 1 - G 5  and GH, energized from the received supply, now radiate signals which are picked up by the interrogator aerial MA, amplified and passed separately via filters F 1 -F 5  and FH, tuned to the generator frequencies to detectors D 1 -D 5  and DH. The output of the detectors is applied to a coincidence circuit CC which when the level of each signal exceeds a predetermined value triggers a mono-stable circuit MS which passes a pulse to modulator MD to interrupt the RF transmission for a short period. This interruption is detected by detector DT which supplies an output signal to trigger the distributer VS into operation. The distributer includes a series of normally cut off transistor circuits equal in number to the number of code digits to be transmitted. The first transistor circuit T1 conducts for a short period on receipt of the detector pulse and during this period the potential on the line V1 increases in value and this increase passed by diodes R11, R13 of a matrix arrangement cuts off generators G1, G3 and signals the first digit. The drop back of transistor T1 to its non-conducting state, after a period determined by capacitor K1 and resistor N1, generates a pulse which triggers transistor T2 into operation and the second digit is signalled by cut off of generators G2, G3 via diodes R22, R23. In this manner the complete identification number is transmitted to the interrogator and applied via the diode detectors to the terminals V1-V5 of a utilization circuit. Generator GH which is cut off during the transmission of each odd digit provides a signal for synchronization purposes at the interrogator.

[Also in Division G3] An automatic level regulating system, particularly suitable for the control of motor vehicle suspension, comprises a differential transformer having a primary winding 1 carried by a piston 4 movable in a cylinder 8 at whose upper and ower ends are disposed the two secondary windings 9 of the transformer, the outputs of which are rectified and summed by a circuit including diodes 11, 12 and a potentiometer 13. The resultant signal is applied to a polarized relay 14 having a central de-energized position of its contact 15 and two extreme contact positions which respectively adjust the position of the winding 1 in one direction or the other to reduce the resultant signal to zero. In the described embodiment the piston 4 is coupled to the suspension system of the vehicle and represents its level, which is automatically maintained at a value corresponding to the setting of the potentiometer 13 by electromagnetic valves (not shown) respectively controlled through the circuits 15, 16 and 15, 17 to vary the gas pressure in the cylinder 8 supplied thereto through a pipe 18. Resistor 20 and capacitance 21 provide a delay to prevent oscillation of the system, and relay 14 has a relatively high hysteresis to prevent small oscillations of the vehicle from causing undesirable switching of the contact 15. Winding 1 is energized from the vehicle battery through an inverter 10.

Title: Improvements in or relating to fertilizers and process for their preparation
Inventor: KLAPPROTH HERBERT
IPC: C05F5/00
Filed: 1961-11-10
Abstract: Fertilizers are produced by adding oxides and/or salts of iron and/or manganese to a permentation waste liquor which has been subjected to partial or complete decomposition fermentation.  The metallic compounds are preferably added after concentration of the waste liquors, e.g. to 20 DEG  B<\>e, in a proportion of e.g. 0,5 to 2,5 g per litre of concentrated liquor.  The compositions are preferably further concentrated, with addition of fertilizer carriers such as peat litter.  A complete fertilizer may be obtained by addition of phosphate fertilizers to the composition. In an example, waste liquor from molasses fermentation, after further fermentation for 3 days, is concentrated to 20 DEG  B<\>e, and then further concentrated to 36 DEG  B<\>e after addition of bog iron ore or manganite.  The composition is then mixed with peat litter and dried.  Any phytotoxic substances in the fermentation waste liquors are rendered innocuous by this process.
