Title: Process and apparatus for purifying heavy fuel oils
IPC: C10G31/10
Filed: 1954-04-09
Abstract: Solid impurities are removed from heavy fuel oils, and the oils are rendered suitable for use as fuels in internal combustion engines and gas turbines, by heating the oil to a temperature in excess of 100 DEG C. and then centrifuging the oil at this temperature in a centrifugal separator at the inlet of which normal pressure obtains and which is provided with means for substantially preventing the evaporating or escape of volatile constituents of the oil at the inlet and outlet.  Centrifuging temperatures up to 150 DEG C. are specified.  Heavy fuel oils mentioned are the residual oils remaining after fractional distillation or cracking of mineral oils, and mixtures of such residual oils with one another or with lighter oils. The oil may be centrifuged twice in succession, in the first stage at a temperature below 100 DEG C., in order to separate water and the coarser solid impurities from the oil, and in the second stage at a temperature above 100 DEG C., in order to free the oil from the remaining solids.  Thus, a temperature of 90-95 DEG C. in the first stage, and of 125 DEG C. in the second stage, may be employed. Constructions of centrifuges are described in which means are provided for substantially preventing the evaporation or escape of volatile constituents of the oil at the inlet and outlet (see Group II).

Title: Improvements in or relating to electronic counting circuits
Inventor: HOUGH GEORGE HUBERT
IPC: H03K23/82
Filed: 1951-05-07
Abstract: 700,201. Electronic counting-apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 2, 1952 [May 7, 1951], No. 10673/51. Class 106 (1). [Also in Groups XL(a) and XL(c)] A multi-stable state circuit comprises two coldcathode gaseous discharge tubes of the type described in Specification 686,317, [Group XL (a)], each comprising a main and a priming discharge gap. Input pulses are applied to the cathodes of the normally discharging priming gap and thus appear at the anode of the priming gap from whence they are applied to trigger the main gap of the tube which was previously not discharged and the other tube has its discharge extinguished. Fig. 1 shows a scale-of-two counting circuit in which if tube T1 is extinguished and tube T2 discharging then positive input pulses applied via transformer TF1 to the cathodes K1, K2 of the priming gaps are transferred to the respective priming gap anodes and thus via networks C1, R5 and C2, R7 to the respective trigger electrodes. The main gap of tube T1 is thus fired and the voltage drop across the common anode load resistor R1 causes the main gap of tube T2 to be extinguished. In a modification shown in Fig. 2 a gate comprising rectifiers MR1, MR2 is connected between the cathode load resistors of the first tube of a pair, the priming gap cathode of the second tube of a pair, and the input pulse source so that the second tube fires only when the first tube is discharging at the main gap and a pulse is present simultaneously at the input. The presence of a load resistor ensures that only one tube is discharging at its main gap at any given instant. In a further modification, Fig. 3 (not shown), each priming gap comprises two separate cathodes one of which is connected to the cathode resistor of the subsequent tube of the chain and the other of which is connected to the input pulse source. A tube will only fire to its main gap when positive pulses are applied to the two priming cathodes simultaneously.

Abstract: 1,254,543. Image signal production. PLESSEY CO. Ltd. 21 Feb., 1969 [6 March, 1968], No. 10832/68. Heading H4F. [Also in Division H1] At least one photo detector and its associated circuitry are situated in or on a substrate, the material of the photo detector and/or of the semi-conductor body containing the circuitry being different to that of the substrate. Thus in the arrangement shown a PN junction photovoltaic diode D is provided by sequential epitaxial deposition of P type and N type Ge layers on a Si substrate, an associated pair of IGFETs Q 1 , Q 2  being formsd of Si. An array of such combinations is provided on a common substrate, the transistors Q 1 , Q 2  being used as switches to sequentially connect the diodes such as D to output terminals O/P in response to pulses provided on co-ordinate conductors X, Y, so as to provide a video pulse train as output. Line and frame sync. pulses may also be provided. Alternatively, the circuitry may comprise a Si IGFET acting as an amplifier for the output from a respective Ge photo-voltaic diode. In this case the output from the amplifiers is sequentially sampled to provide the video pulse train. Various alternative combinations of materials are disclosed; viz. Si or PbS detectors with Si associated circuitry on a sapphire substrate, InAs or GaP detectors with GaAs circuitry on a GaAs or GaP substrate respectively, GaAs detectors with GaP circuitry on a GaP substrate, or detectors of a pyroelectric material such as triglycine sulphate, barium titanate or its derivatives, or wurtzite structure II-VI compounds such as CdS with Si circuitry on a Si substrate. Three methods of compensating for non- uniform sensitivity of the detectors are described. Firstly, the detector array is alternately illuminated with the image being viewed and with a uniform field of illumination, the output from each detector thus being standardized. Secondly, a photographic emulsion is applied over the array, and the emulsion immediately overlying each detector is darkened by illumination to such a degree that the detector output is adjusted to a predetermined level while each detector is equally illuminated. Thirdly, a layer of photographic emulsion is provided over a display surface, e.g. of a cathode ray tube, displaying the output from the detector array under uniform illumination, and the non-uniform sensitivity of the detectors is compensated by selective darkening of the various regions of the emulsion. In a further embodiment, the light input to the array is modulated, an amplifier associated with each detector acting as a phase-sensitive demodulator.

Title: Tractor hydraulic lift system
IPC: A01B63/10
Filed: 1973-03-07
Abstract: 1386576 Tractor hydraulic Systems FORD MOTOR CO LTD 7 March 1973 [8 March 1972] 11163/73 Heading A1P A control mechanism for a tractor hydraulic lift system has passages 15 and 16 in a lift cylinder body 10 supplying fluid to and from the lift cylinder through a lift control valve 46. A constant displacement pump supplier fluid via passage 12 to the valve assembly and fluid is returned to sump via passage 14. A control valve 17 shown in the neutral position in Fig. 1 moves to the left for raising and to the right for lowering the implement. In the lowering position Fig. 4 (not shown) port 26 is uncovered and fluid is fed to chamber 27 thus forcing the unload valve 19 to the right and permitting pump supply fluid in passage 12 to return to sump via passage 14. At the same time control valve 17 progressively uncovers axially spaced metering ports 31 connected with the lift covered as the control valve 17 moves to the left. (Fig. 3, not shown, being the full raise position.) Pressure in supply passage 15 is also fed to chamber 40 in bushing 34 of automatic flow control valve 20. Position of the valve 20 is determined by balance between spring 39 plus pressure in chamber 40 against pressure in chamber 42. Chamber 42 is fed with pump supply pressure from passage 12 via passage 44. The flow control valve 20 operates only when the unload valve 19 is not passing the output of the pump directly to passage 14 and sump. Pressure drop across passages 12 and 15 depends on number of ports 29 uncovered by land 30. In the slow raise position Fig. 2 (not shown) ports 29 are partially uncovered so that pressure drop across passages 12 and 15 is fairly high. In this condition full pump pressure in chamber 42 overcomes combined spring and passage 15 pressure in chamber 40 to move the automatic flow control valve 20 to the left Fig. 2 (not shown) so that the land 35 uncovers port 33 and pump pressure is released via passage 37 to sump. With control valve 17 in full raise position Fig. 3 (not shown) ports 29 are fully uncovered resulting in low pressure drop between passages 15 and 12. In this condition pressure in chamber 40 plus spring pressure overcomes pump pressure in chamber 42 so that valve 20 moves to the right preventing return of fluid via passage 37 and making maximum fluid available for ram operation. In order to prevent overheating by fluid being continually by-passed via passage 37, the valve system is designed so that when the control valve 17 is permitting only a small amount of fluid to pass to the inlet passage 15, the land 25 will uncover groove 26 so as to pressurize chamber 27 and unload the system via passage 14.

Abstract: 1499162 Data processing DIGITAL EQUIPMENT CORP 18 March 1975 [19 April 1974] 11222/75 Heading G4A A memory unit produces an attention signal in response to predetermined internally monitored conditions; when a controller receives the attention signal it causes the memory unit to transmit a signal identifying the memory unit by energizing a selected one of a plurality of control data lines. The attention signal is produced by a flip-flop 300 being set and is transmitted via an AND gate 305. The flip-flop 300 is set, for example, by detection of an error as indicated by an error register 142, or by the output of an AND gate 352 indicating that power is on and the memory unit can accept a command. The unit-identifying signal is produced by a decoder 351 when enabled by the output of an AND gate 350. When the controller receives the unit-identifying signal it causes the contents of a status register 141 in the identified memory unit to be read to indicate the reason for the attention signal being produced. If the status register 141 indicates that an error has occurred the contents of the error register 142 are then read to identify the type of error. A plurality of memory units may be connected to one controller either via separate fuses or a common bus. The flip-flop 300 in each memory unit may be reset, via an OR gate 362, by an INIT signal, which also resets error register 142. Flip-flop 300 is also reset, via AND gates 366, 367 and OR gate 362 when an active transfer command is written into a control register 140 in the respective memory unit. Alternatively flip-flop 300 may be reset in response to a signal which enables an AND gate 370 and hence a multiplexer 371 to reset the flip-flop 300 if the control data line identifying that memory unit carries a "1". Each memory unit may include a magnetic disc, drum or tape.
