Title: Improvements in or relating to carbureters
IPC: F02M7/24
Filed: 1922-12-20
Abstract: 190,725. Nilsson, A. L. Dec. 24, 1921, [Convention date]. Spray carburettors. -The composition of the mixture is regulated by admitting variable quantities of air to a chamber communicating on the one hand with the top of the Boat chamber and on the other hand with the main air passage of t h e carburettor through a passage in front of the throttle valve, said passage receiving fuel from the nozzle. The nozzle 5, Fig. 1, discharges into passage 6 which communicates through holes 10 in choke tube 2 with the main air passage 1, and with a chamber 7 open to the atmosphere through valve 8 and to the top of the float chamber through duct 9. A slow running nozzle 14 delivers fuel into an air duct 11. The valve 8 controls also the inlet 12, Fig. 4, to duct 11 and also an air duct 13 the function of which is, in a certain position of the valve 8, to supply sufficient air to duct 11 to destroy the vacuum therein and stop the flow of fuel through nozzle 14 thus allowing air only to pass to the engine. The fuel issuing from nozzle 5 is intersected by air through chamber 7<1>, the resulting mixture is intersected by air through channel 6 and this diluted mixture is again intersected by an air current after passing through the holes 10, thus producing efficient atomization of the fuel. In the modification shown in Figs. 5 and 6, the throttle valve 15 is of the rotatable barrel type and carries a wedge shape piece 16 which, in the closing positions of the throttle valve, controls the outlet from the passage 6.

Title: An arrangement for checking the frequency sweep of electrical signals produced by a swept frequency transmitting system
Inventor: BRIGGS JOHN NIGEL
IPC: G01S7/40
Filed: 1966-08-04
Abstract: 1,205,392. Radio navigation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 14 Aug., 1967 [4 Aug., 1966], No. 34986/66. Heading H4D. [Also in Division G1] In order to check the " smoothness " of the frequency sweep of a repetitively swept signal a circuit is re-tuned by control signals when its tune frequency departs from the signal frequency and when control signals are not produced sufficiently frequently a fault condition is indicated. The invention is applied to check the re-current frequency sweep (F 1  to F 2 ; F 2 > F 1 ) which takes place over a period of many pulses of a pulsed magnetron radar beacon. The upper and lower limits of the frequency sweep are also checked. In the embodiment a motor-driven cam mechanism 2 controls the frequency of magnetron 1. With switch 4 operated a signal applied on line 5 (e.g. once per hour) initiates a frequency sweep checking operation via a latch circuit 6. A detector 9 is coupled to a cavity wavemeter 8; stepping motor 11 tunes the wavemeter and actuates switches 15, 16. Switch 15 is operated when the wavemeter is tuned just below the frequency F 2  whilst switch 16 is operated when the wavemeter is tuned just above F 1 . The pulse trains depicted are produced from a generator 13 and a control circuit 12; the outputs from flip-flops 24, 25 cause motor 11 to step in the direction for increasing the resonant frequency of the wavemeter which is initially at a frequency just above F 1 , having been returned thereto, after a checking operation by a signal causing motor 11 to step in the appropriate direction. Detailed operation.-On application of a signal to line 5, and operation of the switch 4 when magnetron 1 is at frequency F 1 , latch circuit 6 produces a signal to open gate 18 until magnetron 1 reaches frequency F 2 . As the magnetron frequency rises, pulses from detector 10 give a control signal to cause stepping of motor 11 to raise slightly the resonant frequency of wavemeter 8. The control signal then ceases until the new cavity resonant frequency is reached after which the motor steps on to raise that frequency once more. If the initial frequency of the frequency sweep is below the desired minimum by more than a predetermined amount there will be an undue delay before any pulses from unit 10 are produced; or if the frequency sweep does not rise smoothly there will be an undue pause in the production of the pulses: either fault is detected by a monostable circuit 14. If the initial magnetron frequency is above the " parking " frequency of the wavemeter, detection is also by circuit 14. If the magnetron does not reach the upper frequency limit, switch 15 fails to operate. And failure of switch 15 to operate within a predetermined time indicates that the rate of frequency sweep is too low.

Title: Improvements in or relating to adaptive model derived control systems
Inventor: FELLGETT PETER BERNERS
IPC: G06G7/66
Filed: 1967-07-31
Abstract: 1,240,825. Adaptive analogue models. NATIONAL RESEARCH DEVELOPMENT CORP. 31 Oct., 1968 [31 July, 1967], No. 35095/67. Heading G4G. An adaptive model derived control arrangement contains a model of a system to be controlled; comprising a filter having a minimum phase transfer function of output corresponding to the predicted system output with zero time delay; a time delay circuit in series with the filter; a feedback path from the filter to simulate closed loop operation, and a further feedback path from the difference between the system and time delay circuit output to effect closed loop operation of the arrangement. In Fig. 8 a command signal C is applied over filter D introducing a required response characteristic to produce a required output OP = CD; the filter output being applied to a comparator circuit together with a predicted output signal 5 to produce error signal 6 applied to control path filter 1/S<SP>1</SP>1. A control signal 1 is applied to system S introducing noise perturbation and supplying output OP while the control signal also feeds a system model circuit S 1  whose predicted output due to control action 2 is applied to a time delay circuit # energizing a comparator also receiving the output signal. The error is applied over a Wiener linear predictor (Fig. 11, not shown) to produce predicted output 4 in absence of control action, which is added to signal 2 to produce a predicted output 5 taking account of previous control action and noise, which is applied to the input comparator. A comparator of the output of delay # with the system output is applied to adaptively adjust 1/S<SP>1</SP> 1 , S 1 , # and the predictor, while the latter is also adjusted in response to the autocorrelation function of the predictor input waveform. Anticorrelation, Fourier transformation, and minimum phase angle computation may be effected digitally by programmed algorithms or alternatively by analogue methods (Fig. 9) wherein a nth order polynomial transfer function is obtainable utilizing n integrators e.g. realized on a single silicon chip. As shown, a transfer function is obtainable; the input V 2 <SP>1</SP> being applied directly to potentiometers α 0 , α 2  and inversely to potentiometer α 1 ; and the output energizing directly potentiometers # 0 , # 2  and inversely potentiometer # 1  The integrators are cascaded from potentiometer α 0  to output, and the first receives also a signal from # 0 ; the second receives also signals from α 1 , # 1  and the third signals from α 2 , # 2 . A mathematical analysis is given.

Title: Improvements in or relating to the preservation of green peas by canning
IPC: A23L1/275
Filed: 1928-12-08
Abstract: 325,622. Onofrio, G. d'. Dec. 8, 1928. Colourings; preserving green peas. - In canning green peas, the peas are treated with green dyestuffs consisting of light green SF, or of salts of sulphonated derivatives of dibenzyldiethyl-diamino-triphenyl-carbinol acid anhydride such as Guinea green B, together with a yellow or orange colour, to improve their appearance. The Yellow and Orange colours used include tartrazine, Yellow AB, Yellow OB. Orange I of tropaeolin and Naphthol yellow S. The process may be effected by first boiling and colouring the peas in enamelled or wood vessels which may be heated by steam coils of enamelled iron. The peas are placed in an osier or willow or perforated enamelled metal basket or crate which is inserted in the vat which contains water and the colouring materials, and are gradually heated up to about 80‹ C. The peas are withdrawn after about 20 minutes and immersed in a wood vat containing a fixing bath which may consist of a dilute solution of aluminium salts, e.g. 25 gm. of aluminium chloride dissolved in 100 litres of water, the peas being partially cooled therein. The peas are next washed for 5 minutes in running water to remove excess of colouring matter and broken peas, and are then ladled into the cans or other containers to which salt water rendered acid, for example with citric, tartaric or lactic acid has already been added. The cans are sealed, and sterilized in an autoclave at about 115‹ C. The cans used are varnished on the inside with a material which will not be affected during. the sterilization. A suitable colouring bath consists of 5 gm. of Guinea green B or 5 gm. of Light green SF, 15 gm. of Naphthol yellow S and 25 gm. of citric or other suitable acid, all dissolved in 100 litres of water. A decigram of colouring matter is needed for each kilogram of peas, the treated peas containing less than 5 centigrams of colouring matter per kilogram. Identification tests for the treated peas are given.
