Title: Improvements in or relating to the production of colouring malt and caramelized malt
IPC: C12C1/18
Filed: 1929-12-30
Abstract: Colouring or caramelized malt is produced by roasting wheat malt or rye malt without crushing or flaking the grain.  As applied to wheat malt the roasting is started at not more than 40 DEG  C., the temperature then raised slowly within the first 15 minutes to about 60-70 DEG  C. and then raised finally to about 140-160 DEG  C. within the next 30 minutes.  The malt may be kept at 60-70 DEG  C. for about 30-40 minutes before being raised to 140-160 DEG  C.  For the rye malt the moisture content is partly reduced by treatment with air at 30 DEG  C.  The temperature is now raised in about 30 minutes to 50-55 DEG  C. with a further increase to 65 DEG  C. when it is kept for 50 minutes for saccharification.  The temperature is then raised rapidly to 130 DEG  C.ALSO:Colouring or caramelized malt is produced by roasting wheat malt or rye malt without crushing or flaking the grain.

[Also in Division H2] A transmitter, for use in a battery-operated rescue beacon in the UHF band, employs semiconductors throughout and comprises a crystalcontrolled oscillator and one or more amplifier stages, which operate at a sub-multiple of the UHF to be radiated, and deliver power to the aerial via a frequency multiplying circuit. For battery economy, the UHF output is in bursts of 0À65 sees. duration at 3À5 sees. intervals and the output is pulse modulated at 1 kc. Both modulations are effected by control of the power supplies to the transmitter. The transmitter circuit comprises an oscillator 10 tuned to operate at 60À75 Mc/s. delivering 60 mW to intermediate class C amplifier stage 20 which delivers 120 mW to class C power amplifier 30 providing 1W over a " pi " matching network C 3 L 2 C 4  to a frequency multiplier stage 40. Here the signal is fed over a variable capacitance diode C y  to a circuit L 4 C 5  tuned to the fourth harmonic and which delivers about 0À5W at 243 Mc/s. to aerial 50 via a rejector circuit L 5 C 6 C 7  tuned to the fundamental. The power supplies for the various stages of the transmitter are obtained from a transistor oscillator D.C.-D.C. converter 60 as described in Specification No. 1,025,101. The converter 60 provides an asymmetric rectangular waveform, Fig. 2 (not shown), at 1 kc. which is switched on for 0.65 sec. bursts at 3À5 sees. intervals by a transistor multivibrator switch 80. The power supply for stages 10, 20 of the transmitter is obtained by rectifying and smoothing the output of the converter at MR 1 , C8. Supplies for stages 30 and 40, however, are unsmoothed whereby each 0À65 sec. transmitted signal burst is pulse modulated at the audio frequency of 1 kc.

Title: Fuel enrichment control circuit for an internal combustion engine
IPC: F02D41/14
Filed: 1975-10-07
Abstract: 1492900 Automatic control systems FORD MOTOR CO Ltd 7 Oct 1975 [30 Oct 1974] 40938/75 Heading G3N The fuel supply to an I.C. engine is enriched if the measured engine acceleration is above a pre-set value and in a given frequency range. The enrichment is inversely proportional to the sensed engine temperature. As shown, a signal on input 110 having a frequency proportional to engine speed is integrated by amplifier 120 to form a voltage dependent upon the speed. This voltage is applied to a T-filter, differentiator and threshold circuit 18 which gives an output if the engine acceleration (or deceleration) is within a given frequency range indicative of engine roughness and is above a pre-set value. Provided the engine is running as sensed by circuit 20 from the input 110, and the above conditions are met, switch 46 is opened to open switch 44 and allow a signal inversely proportional to engine coolant temperature (as measured by thermistor 22) to pass via amplifiers 64 and 92 to form an output signal V that is used to enrich the engine fuel supply e.g. of a fuel injection system. The fuel is also enriched by opening switch 42 if the engine is being started, as sensed by circuit 20 from the engine ignition switch. The gain for the temperature dependent signal via switch 42 is different than via switch 44. In both cases the fuel enrichment is inversely proportional to engine temperature, and is multiplied by an engine fuel demand signal to form a fuel control signal. If the engine is not started and the acceleration is not  within the given frequency range and above the pre-set value, the fuel is enriched by a signal of fixed magnitude as set by potentiometer 70 in switching circuit 12.
