Title: Improvements in and relating to internal combustion engines
IPC: F02D1/00
Filed: 1953-10-13
Abstract: 740,178. Regulating. REGIE NATIONALE DES USINES RENAULT. Oct. 13, 1953 [Nov. 7, 1952], No. 28224/53. Class 7(6) [Also in Group XXVIII] In a spark ignition engine with injection of fuel into the cylinders, the air supply to the cylinders is uncontrolled and the fuel supply circuit 9 to each fuel injector 8 comprises a by-pass orifice 17 controlled by a valve 18 which is opened periodically by means of an adjustable rotating cut-out distributer member 24 to cut out the fuel supply to the corresponding cylinder periodically and thus reduce the power output of the engine to a power output fraction p/q where p is equal to the number of fuel injectors which take place during a number q of cycles in the cylinder, the distributer 24 comprising a number of distributer units equal to the number of power output fractions to be obtained in the engine. In a two-stroke engine each injector 8 is supplied by a pump 11 actuated by a camshaft 12 driven at crankshaft speed w and the by-pass valve 18 is normally held closed by an electromagnet 20, the circuit of which includes the cut-out distributer 24. The distributer 24 comprises a drum, Fig. 3, of conducting material divided into a number of sections equal to the number of power output fractions, e.g. nine sections corresponding respecitvely to power outputs of 1/9th; 2/9ths; 3/9ths...9/9ths of the total power output, the drum being driven at a speed of w/9ths the drum being driven at a speed of w/9 and adjustable axially to bring a different section opposite a contact brush 1 in the circuit of electromagnet 20. Each section of the drum has insulating segments 28 corresponding to its respective power output fraction; for example the 2/9ths power section has circulating segments extending over 7/9ths of its circumference so that the circuit of the electromagnet 20 is only completed on two out of every nine cycles to allow injection to take place, the circuit being broken on the remaining seven cycles to allow the valve 18 to open the by-pass orifice 17 and prevent injection taking place. The drum 24 is movable axially through a resilient connection 29 by an accelerator pedal 30, Fig. 3, overspeeding being prevented by a centrifugal governor 31. Alternatively the accelerator control may be omitted or the governor 31 may cut off the current to the electromagnet when a predetermined speed is exceeded. In a multicylinder engine, e.g. a four-cylinder engine, additional contact brushes 2... 4, Fig. 1 are arranged around the distributer 24, each contact controlling a separate fuel injector.

Title: Improvements in or relating to electric generators
IPC: H02K23/40
Filed: 1952-11-12
Abstract: 757,316. Exciting dynamo-electric machines. MACFARLANE, J. C., MACFARLANE, W. I., and MACFARLANE, J. W. July 16, 1953 [Nov. 12, 1952], No. 28488/52. Class 35. The output of a generator is regulated by means of a stabilizing generator excited from the generator current or voltage to be controlled and having saturated field parts 17 and unsaturated field parts 19 excited in series but acting in opposition on the armature so that they are balanced at a set output current or voltage, and any deviation causes a correcting voltage to be generated by the exciter and fed to the generator field, the output being set by a main source of excitation, suitably compounded for load, outside the stabilising exciter which only operates when the controlled current or voltage deviates from its set value. The stabilizing winding, fed by the stabilizing exciter, may be mounted on the interpolar axis of the main generator or its exciter as described in Specification 593,817. As shown in Fig. 4, where the invention is applied to the voltage regulation of a D.C. generator 27, the main excitation is derived from shunt field winding 28, compounded by brush shifting or by means of a series winding 30. The opposing field windings 18, 20 of the stabilizing generator 22 is excited from the load voltage and its output fed to an additional field winding 29. The generator may be of the type described in Specification 519,538. By the use of suitable series compounding on the main generator, the invention may be applied to the control of a generator driven by an ungoverned water turbine. By the use of a resistance shunt, the stabilizer may be used on constant current generators ; and A.C. generators, excited from their rectified output, may also be similarly regulated, through an intermediate exciter if necessary for large machines. The speed of response may be improved by the use of an injector transformer whose primary is connected in parallel with the stabilizer fed field winding 29 and the secondary is connected to a winding on the main pole of the stabilizer. Fig. 11 shows how the invention may be applied to the speed regulation of a motor 44. A tachometer generator 45, driven by the motor, feeds the opposing windings 18, 20 of the stabilizer 22 which in turn controls the motor field 46. Specifications 713,633 and 757,304 also are referred to.

Patent GB-1009266-A (GB)
Title: Frequency-modulation receiver for stereophonic or monophonic signals
IPC: H03D1/22
Filed: 1962-07-25
Abstract: 1,009,266. Stereophonic radio receiving systems. ZENITH RADIO CORPORATION. July 25, 1962 [July 31, 1961], No. 28559/62. Heading H4L. Relates to a receiver for stereophonic signals of the type in which a carrier is frequencymodulated by the A + B audio signals, the A - B signals amplitude modulating a subcarrier which is suppressed and the resultant signal frequency-modulating the main carrier, and a further pilot signal for reconstituting the subcarrier at the receiver also frequency-modulates the main carrier. The receiver may be used for stereophonic or monophonic reception and adjusts itself automatically in accordance with the character of the received signal. As shown, the receiver comprises conventional circuitry as far as the ratio-detector 13 which is followed by a pair of push-pull arranged channels which respectively derive the A and B audio signals directly from the composite signal from the ratio detector. The composite signal is supplied via a cathode follower 31 to the centre tap of the secondary winding of a transformer 20 tuned by a capacitor 22 to the subcarrier frequency, and the subcarrier is regenerated at 40 from the pilot signal and supplied to the primary winding of the transformer. Considering channel A, a pair of peak detectors 26a, 27a are connected with the anode of diode 27a and the cathode of diode 26a to a sampling capacitor 25a, and the anode of diode 26a, and the cathode of diode 27a through a time-constantnetwork 28a, 29a, are connected to opposite terminals of the input circuit. The diodes 26b, 27b for the B channel are connected similarly. The time constant of network 28a, 29a is such that diode 27a only conduits during the peak portion of a demodulation signal but diode 26a is held conducting when there is no subcarrier signal by a bias derived from the cathodefollower 31 and potentiometer 33, 34, the B channel being arranged likewise. In operation, the demodulating signal from 40 which may be in the form of pulses at the sub-carrier frequency and alternating in polarity, keys the diodes. Negative portions cause diodes 26a, 27a to conduct simultaneously and the sampling capacitor 25a assumes a charge which represents the instantaneous potential of the peak portion of the sub-carrier appearing in the composite signal from the ratio detector, i.e. the potential across cathode-resistor 30. The deemphasis filter removes the step-like characteristic and the resulting A signal is supplied to the amplifier 45a. Similarly, the positive portions of the demodulating signal cause diodes 26b, 27b to conduct simultaneously and cause capacitor 25b to follow the opposite peaks of the sub-carrier in the combined signal this representing the B signal. A graphical explanation of the demodulation process is given. When a monophonic signal is received there is no demodulation signal from 40 and the conducting diodes 26a, 26b pass the demodulated signal from the ratio detector 13 without modification; each loud-speaker producing the same signal. Specification 1,009,265 is referred to.

Title: Improvements in grabs
IPC: B66C3/12
Filed: 1934-10-06
Abstract: 433,104. Grabs. VOORWINDE, W., 93B, Pretorialaan, Rotterdam, Holland. Oct. 6, 1934, No. 28678. [Class 78 (iv)] A grab is constructed with (1) alternative connections between the closing rope and lifting cable, (2) means for varying its capacity, (3) means for varying the power necessary to close the bucket sections, and (4) means for exerting a scraping action on the walls to remove adherent material. Fig. 2 shows a closing rope 9, either end of which can be attached to the hoisting rope while the uncoupled end 10 bears against the grab frame, or alternatively both ends of the rope can be connected to the hoisting rope. In addition Fig. 2 shows one means for varying the capacity. The extension or wing portions 14 can be extended fully, as shown, and fixed to the main sections by pins 15, or they can be swung round the pivots 13 to fold inside the main sections and the pins 15 then passed through the holes 16. Fig. 4 shows a means of varying the power required for closing, without varying the capacity. The links 18, interposed between the suspension rods 2 and the bucket sections, can be fixed by pins 21 in the positions shown, or the links may be moved outwards into register with the holes 20 and pinned thereto. In the latter case the force necessary for closing, acts with greater leverage and is correspondingly less than when the links are in the position shown. If the links are left unpinned, they rotate to some extent as the grab is opened and closed, and can be fitted with arms to contact with the interior of the buckets and act as scrapers to remove adherent material. Fig. 7 shows a construction in which both the power and capacity are varied. The links 23 can be fixed in an in-turned position as shown, or be rotated and fixed in a corresponding out-turned position, or they may hang freely in alignment with the links 2. In the in-turned position, plates 25 on the arms 2 limit the capacity of the grabs.

Title: A process for dyeing wool fast tints
Filed: 1930-09-26
Abstract: Acid wool dyes, dyeing with.--Wool is dyed fast tints by treatment first in a bath of an acidity substantially less than that corresponding to 3 per cent of sulphuric acid (calculated on the weight of the wool) and containing a chromium compound of an azo dyestuff derived from a substituted or unsubstituted 1-diazo-2-naphthol-4-sulphonic acid and a substituted or unsubstituted naphthol, and subsequent development of the dyeing on the fibre in a more strongly acid medium.  In an example 100 parts by weight of wool are first treated for \ba1/4\be hour in a bath at 190 DEG  C. containing in 2000 parts of water 5-6 parts of formic acid and 3-4 parts of the chromium compound of Example (1) of Specification 364,147, the temperature is then raised to boiling in \ba1/2\be hour, and the boiling is continued until the dyestuff is absorbed, whereupon 6-7 parts of conc. sulphuric acid are added and boiling is continued for \ba3/4\be-1 hour; the wool is dyed a deep black tint of very good fastness.  The formic acid may be replaced by sulphuric acid in amount corresponding to a similar acidity; alternatively mineral acid may be added to the bath very slowly or a formate may be added at the commencement. The dyeing of wool in baths containing both a chromium compound of an azo dyestuff and an azo dyestuff capable of reacting with the chromium compound to form a mixed azo dyestuff containing chromium is disclaimed.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the dyeing of animal fibres in general in a weak acid medium with a dyestuff containing metal and developing the dyeing with a stronger organic or inorganic acid and includes a further example in which 100 parts by weight of wool are first treated for \ba1/4\be hour in a bath at 60-70 DEG  C. containing in 2000 parts of water 5 parts of acetic acid and 4 parts of the chromium compound from nitrated 1-diazo-2-naphthol-4-sulphonic acid and 3-methyl-5-pyrazolone, raising to boiling temperature in \ba1/2\be hour, maintaining boiling for \ba1/4\be hour adding 6-8 parts of sulphuric acid and boiling until the tint and the fastness are fully developed.  This subject-matter does not appear in the Specification as accepted.
