Abstract: 1,199,575. Electron guns. ENGLISH ELECTRIC VALVE CO. Ltd. 26 Oct., 1967 [17 Dec., 1966], No. 56588/66. Heading H1D. In an electron beam tube, e.g. a klystron tube, the cathode 2 having a cathode coating 1 has a central hole 3 backed by a cylindrical cup-like structure 41, e.g. of molybdenum, for receiving positive ions returning to the cathode along the axis of the tube. The structure 41 completely closes off the hole 3 from the space behind the cathode, in which is situated the cathode heater, and so prevent molecules of material, released during processing of the tube, from passing from the rear of the cathode to the cathode coating.

Filed: 1968-12-05
Abstract: 1298551 Teaching machines TONESCRIPT PRODUCTIONS Ltd 5 Dec 1969 [5 Dec 1968] 57825/68 Heading G5G In a programmed question-and-answer teaching machine a medium such as a card has a number of questions and of answers visibly recorded on it and when the card is in position on the machine all the questions and answers are visible, the user being required to decide which answers belong to which questions. However, the machine determines the sequence in which the questions are to be tackled. Fig. 1 shows the housing of such a machine: L1 to L2 are question.indicating lamps and RS1 to RS12 are answer-selecting switches. In use, a card (not shown) bearing written questions and answers has an aperture adjacent each question and answer, the apertures being in a pattern corresponding to the lamps and switches of the machine. When the card is placed on the machine's top panel with its apertures in register with the lamps and switches, the machine presents questions by sequentially illuminating different lamps and the user responds by means of the switches. More than one question lamp may be lit simultaneously, in which case the correct response is the operation of all the switches of the corresponding answers, and no others. When a correct response has been made to a single or multiple question, the machine automatically proceeds to another in a predetermined programme controlled by a rotary stepping switch. In particular, the machine shown may present five of the twelve possible questions and the user presses five switches, all of which are held in if they correspond to correct answers (the question lights going out one by one as their corresponding answers are entered), but all the switches depressed are released as soon as one wrong answer is entered and all five questions are re-presented. If all five answers are correct, the switches unlock, the stepping switch advances and a different set of five questions is presented. In a full programme, individual questions are repeated several times but are grouped with different questions each time. When a programme has been completed, it may be automatically repeated. Eventually however, a new programme is called for, and for this a new card must be used. This will in general call for a different sequence of contacts to be made by the stepping switch: a switch SS on the panel is operated to make the necessary changes in internal circuitry of the machine. This circuitry is depicted in Fig. 2 (not shown). In alternative machine constructions, the question lamps and answer switches may be placed in parallel columns for use with a card to be located in the space between these columns. It is also possible to replace the separate lamps and switches by a single set of push-button switches with lamps built into them so that each is a combined question indicator and answer selector (though not in general relating to the same question and answer pair).

Title: Magnetic bubble domain devices
IPC: G11C19/08
Filed: 1972-12-14
Abstract: 1374722 Moving domain systems ROCKWELL INTERNATIONAL CORP 14 Dec 1972 [27 Sept 1972] 57847/72 Heading H3B A bubble domain generator comprises an overlay 10, Fig. 2, by which a seed domain is held captive, two bar overlays 12, 13, and a conductor 11 which passes over one or both the bars. As the in-plane field of the bubble device rotates, the seed domain 14 is stretched out by the poles induced on bars 12, 13 by the field, aided by the nose 10A on overlay 10. A current is then passed through the conductor 11 which tends to repel the domain from point B and attract it to point A. This severs the domain and part of it passes via Y bar 15 to a propagation path while the other part reforms the captive domain. The bars 12, 13 are at an angle so that the rotating field first attracts the captive domain along nose 10A to 12A and then to 13A. The nose portion is not essential. In Fig. 3 (not shown) the angle between the bars is greater and the conductor passes only over the first bar. Relative dimensions of the overlays are given.

Abstract: 1,211,950. Centrifugal separators. ETABS. ROUSSELET (SOC. A. RESPONSABILITE LIMITEE). 27 Nov., 1969 [4 Dec., 1968], No. 57990/69. Heading B2P. In a centrifuge for purifying contaminated liquid a pressure sensitive switch 16, Figs. 1 and 2, is positioned in an outlet pipe 10 connected to an evacuation nozzle 9 and, in use, controls the operation of opening and closing members 17, 18 of the circuit 12, 13, that conducts separated liquid 8 and/or sediment 7 away from the centrifuge, as a function of the pressure existing in the outlet pipe 10. The members 17, 18 may be constituted by electrovalves. In operation, when the nozzle 9 penetrates into the sediment 7, the resulting increase in pressure in the pipe 10 is detected by the pressure sensitive switch 16 which actuates the closing of the electrovalve 17 and the opening of the electrovalve 18. After removal of the components the switch 16 actuates the closing of the valve 18 and the opening of valve 17 for the next removal of liquid. In a modification, the valve 18 is replaced by a bypass valve opening automatically beyond a certain pressure. In Fig. 3, evacuation of stiff, pasty sediment is effected through openings 19 provided in the bottom of the centrifuge bowl 4 by means of a scraper knife 20 which is caused to penetrate the sediment by the pressure sensitive switch 16 as soon as the nozzle 9 comes into contact with the sediment 7. The switch then closes the valve 17, places the scraper knife 20 into motion and causes the nozzle 9 to retract. In a modification, Fig. 5 (not shown) the centrifuge bowl is mounted horizontally and the sediment removed by the scraper knife is evacuated through a pipe extending from one side of the centrifuge bowl.

Abstract: 1,203,705. Electron microscopes. SIEMENS A.G. 11 Dec., 1968 [28 June, 1968], No. 58790/68. Heading H1D. In an electron microscope or similar corpuscular beam instrument for studying the phase or amplitude characteristics of objects in which there is a phase-correcting foil having a phaseshifting characteristic that varies as a function of radius to allow for the phase-shifting aberrations of, e.g. the objective lens, as described in Specification 1,150,967, the thickness d of the foil is varied with radius r in the manner shown in order to avoid a reduction of the contrast in the image due to the increased thickness of the foil. The foil has sharp concentric discontinuities in thickness at 4 corresponding to a phase shifting decrease by a whole number multiple of # and intervening annular zones 3, 5, 6 where the thickness increases continuously. The innermost zone which surrounds the aperture 2 has a minimum thickness at 1. The foil may be associated with a fine beam lens in a scanning microscope. The foil may be made by irradiation with an electron beam in a hydrocarbon atmosphere so as to grow a carbon layer of desired distribution. Alternatively a previously applied carbon layer may be decomposed by irradiation with an electron beam in an oxygen atmosphere.

Patent GB-2007787-A (GB)
Title: Anti-skid fluid-pressure operated vehicle braking system
IPC: B60T8/50
Filed: 1978-10-23
Abstract: In a fluid-pressure operated anti- skid braking system operation of a brake applying relay valve 2 is controlled by application pressure in an application chamber 12. A memory chamber 25 is connected to the application chamber 12 through a one-way valve 26 and a restrictor 27 which permits pressure in the memory chamber 25 to decay into the application chamber 12 when the pressure in the application chamber 12 reduces at a skid point. Application pressure is supplied to the application chamber through a normally open latch valve 14 and a restrictor 18 in a by-pass passage 16, 17. Re-application of the brakes following a skid is controlled by closure of the latch valve 14 which permits only a restricted flow of application pressure through the restrictor 18 into the application chamber 12. This is sufficient to re-apply the brakes rapidly in a first stage until the pressure in the application chamber 12 becomes equal to that of the decayed pressure in the memory chamber 25 and the valve 26 opens. Brake-application then continues at a lower rate in a second stage since the restricted flow of control pressure has also to increase the pressure in the memory chamber 25. This continues until the latch valve 14 re- opens so that the brakes are re-applied in a third stage at an original application rate. The maximum pressure differential between the chambers 22 and 25 is limited by a valve spring 30 to advance the beginning of the third stage after a prolonged skid signal. <IMAGE>

Title: Apparatus for Measuring the Flow Rate of a Liquid
IPC: G01F1/00
Filed: 1979-06-12
Abstract: Apparatus for measuring the flow rate of a liquid, such as water, flowing in an open channel, such as an irrigation channel, comprises a gate 11 mounted transversely across the channel 10 and pivotable about a horizontal axis 12 less than about one third of the way up the gate. The base of the gate 11 has a counterweight 13, which tends to hold the gate in a vertical position in which it blocks the channel 10. Thus the liquid level upstream of the gate 11 rises, until the mean line of the force the liquid exerts on the gate is above the axis 12, whereupon the gate pivots open and releases the trapped liquid. The counterweight then returns the gate to its vertical position. The frequency of the pivoting movements of the gate 11 is a measure of the flow rate of the liquid. The spindle or shaft about which the gate 11 pivots is connected to a mechanical totalizator, which provides an indication of the total volume of the liquid flowing in the channel. The gate may be linked to a second gate upstream of gate 11 which is closed when gate 11 opens and is shut when gate 11 closes. Gate 11 may measure only a proportion of the flow, the remainder passing over weirs in parallel. <IMAGE>
