Title: Fuel injection systems
IPC: G05D13/00
Filed: 1971-09-09
Abstract: 1366172 Valves ROBERT BOSCH GmbH 9 Sept 1971 [10 Sept 1970] 42061/71 Heading F2V [Also in Division G3] A speed governor for a fuel injection system of an I.C. engine comprises a rotating shaft 2 carrying a valve spool 4 at one end thereof which is urged outwardly by centrifugal force, and a flyweight 29 acting against the outward movement of the spool after a predetermined speed of the shaft has been reached. Fluid is fed through passages 6 and 8 to the spool. As soon as the spool is displaced by centrifugal force fluid pressure is applied to chamber 13 via a passage 25 and further to a fuel regulating member 22 via a passage 18 and piston 21. When the pressure in chamber 13 is sufficient to overcome the centrifugal force on the spool, the spool is pushed back to its former position. As soon as the engine speed decreases the spool is displaced in the opposite direction and fluid passes from chambers 13 and 19 via port 25 and pipe 27 to the reservoir. At low engine speeds or when the engine is not running, the flyweight 29 is pressed against the spool by a spring 31. The spring 31 is compressed as the engine speed increases until the flyweight 29 abuts against the head 33 of the spool. In a second embodiment (Fig. 5, not shown) the flyweight (29<SP>1</SP>) acts indirectly on the spool by way of a spring (31<SP>1</SP>).

Title: Multiplexing connection between a key board an a circuit
IPC: G07G1/00
Filed: 1972-09-13
Abstract: 1402654 Keyboards SHARP KK 13 Sept 1972 [13 Sept 1971] 42519/72 Heading G4H In keyboard apparatus, the keys are scanned to produce a signal at a time respective to the actuated key, this signal causing a respective number of pulses to feed a counter, the count being fed to a register. In Fig. 1, which shows a calculator, the keys in a keyboard KB enable respective gates (e.g. AG6) to pass timing pulses T5-T14. The timing pulse corresponding to the operated key passes via an OR gate OG1 and by means of flip-flops Q1, Q2, Q3 gates timing pulses t1 through a gate AG3 until a time T16, flip-flop Q2 preventing repeated entry during a single key operation. The pulses passed through AG3 are added to a 4-bit register XF recirculating via a serial adder FA (or a counter or subtractor could be used). A flip-flop FN indicates whether the key entry was a numeral or a function command (add, subtract, multiply, divide). If a numeral, it is gated AG5 to a main register X. A function command is passed in parallel to be decoded at CD. The keyboard timing pulses may pass through the switches when closed, instead. Fig. 5 (not shown) shows a modification in which the numeral 0 uses the "function" input to the OR gate corresponding to OG1 instead of the "numeral" input, and the arrangements between this and the adder are somewhat different. The keyboard timing pulses can also be used to enable digit displays in turn, for the result of the calculation. Application to cash registers and price-computing scales is also mentioned.

Title: Improvements in the cold separation of gas mixtures
IPC: F25J5/00
Filed: 1961-12-01
Abstract: 946,009. Cold separation of gas mixtures. LINDES EISMASCHINEN A.G. GES. FUR. Dec. 1, 1961 [Dec. 1, 1960], No. 43065/61. Heading F4P. Simultaneous purging and cooling of cyclically switchable regenerators 1 . . . 7 thereby evaporating a high boiling point impurity having been condensed therein during the previous period e.g. carbon dioxide content of converter gas containing hydrogen, methane, carbon-monoxide and hydrogen sulphide is effected by a reverse flow of an alien gas e.g. nitrogen in quantity about equal to that of the feed gas and having been cooled by heat exchange with the purified converter gas in a second set of cyclically switchable regenerators 8 . . . 12 after the purified gas has been washed with a liquified portion of the alien nitrogen in a column 23. As shown converter gas is forced by a compressor 14 through regenerators 1 to 3 in parallel where it is joined by residual purified gas blown from regenerator 4 by the alien nitrogen, and the so purified mixture after being further cooled in countercurrent exchangers 20, 21 is fed through a duct 22 to a column 23 where it is washed with liquid nitrogen obtained, by expanding at a value 24<SP>1</SP> cold compressed nitrogen gas which in turn is obtained from compressors 16, 18, 26 in series, which discharge through countercurrent exchangers 27-29 and a duct 24. The cold content of the substantially pure hydrogen effluent from column 23 is recovered in exchanger 20, and also in exchangers 10, 11 of cyclically interchanged regeneration 8 . . . 12. The so-warmed hydrogen effluent passes to a duct 32 where it is joined by a portion of pure nitrogen leaving compressor 16 before being fed to an ammonia synthesis plant. Supply of cold nitrogen purging gas for the regenerators 5-7 being derived is obtained by passing cold pure nitrogen withdrawn from regenerators 8, 9 cooled by effluent during the previous period through exchanger 27 where it is warmed prior to expansion in a turbine 33 and passage through said regenerators 5-7 from which nitrogen loaded with carbon-dioxide is discharged through a duct 35. On switching over to the succeeding period of operation, regenerators 1, 2 and 7 are traversed by feed converter gas, regenerators 4, 5 and 6 are traversed by alien purging gas whilst regenerator 3 is traversed by compressed nitrogen from line 19. Also regenerators 8, 12 are traversed by pure nitrogen, regenerators 9, 10 by purified gas and regenerator 11 by a portion of the cooled nitrogen leaving regenerators 8, 12. In a modification the alien nitrogen contains 4% oxygen and after being cooled in regenerators 8, 9, Fig. 2 (not shown), is passed directly through regenerators 5 to 7 on purge. Washing nitrogen for column 23 is obtained by compressing pure nitrogen from a separate supply.

Screw adjusting shafts 436, 437 see also Figs. 7, 11 (not shown) are provided and the magnetizer has a ring 439, Fig.1, of aluminium so as not to distort the magnetic field into and out of the pipe. Control circuit pre-amplifiers for the pivoted detector shoes 416, 417 are contained within casings 420, 421 which rotate with the assembly. In operation, the whole detector including the shoes is adjusted to accommodate the diameter of pipe under test and rotates around the pipe which moves axially therethrough. If a flaw in the pipe is large enough to alter the flux pattern then this disturbance is picked up by the coils 521 in the rotating detector shoes and generates an electric signal, Fig. 19. The coils 521 are connected via pre-amplifiers 525 and variable attenuators 526 to amplifiers 527, OR gate 528 and indicator 529. Should the shoes 416, 417 strike projections from the pipe then they will bounce radially away as permitted by the lost motion shoe mounting arrangement of Fig.13 (not shown).

Title: Arrangement for the control of vehicles particularly of radio remote controlled model vehicles
IPC: G05D1/00
Filed: 1977-10-19
Abstract: The arrangement has a smaller transmission factor for small course corrections but a larger transmission factor for larger course corrections without switching over being necessary. Extreme positions of specific elements which are not normally considered can also normally be set very rapidly. A potentiometer (90) of the radio remote-control system is connected via resistors (91, 92) to terminals (93, 94) of a supply voltage. The resistors (91, 92) can be bypassed by short-circuit switches (95, 96). These short-circuit switches are constructed as limit switches which can be actuated by the slider of the potentiometer (90). In the limit positions of the slider of the potentiometer (90), the short-circuit switches (95, 96) are therefore closed and bypass the resistors (91, 92). As a result, the supply voltage of the terminals (93, 94) is applied directly to the terminals (97, 98) of the potentiometer (90). <IMAGE>

Abstract: 1,176,253. Telegraphy. SIEMENS A.G. 27 Sept., 1967 [28 Sept., 1966], No. 43887/67. Heading H4P. In a telegraph system in which transmitted characters can be checked for error, e.g. by parity, the receiver checks each character for error and if no error is found each bit is checked to detect error not revealed by the character check. In the embodiment described, transitions in the received character, which includes a parity bit, are passed to first and second bi-stables which are enabled for a time lying symmetrically about each theoretical mid-bit point. The first bi-stable changes state if a transition occurs while it is enabled, and it remains in this state. The second bi-stable changes state at each transition when enabled, thus making an odd/even count of these transitions. If, at the end of the character, there is an even count, i.e. it is possible that the character is faulty although the character parity check has revealed no error, and if the first bi-stable has changed state an error-indicating signal is generated. Reference is made to the use of constant ratio code, and codes with various Hamming distances. The bit checking arrangement may include a threshold unit.
