Abstract: 1,075,908. Liquid level indication. DEUTSCHE ERDOL A. G. March 18, 1966 [March 25, 1965], No. 12000/66. Heading G1H. [Also in Division F4] In a means for determining the level of the interface between a fluid and a displacement liquid in an underground reservoir a fluid, such as fuel oil, petrol, propane or butane, is delivered to or withdrawn from a cavity 1 through a flowmeter 7, pipe 8 valve 9 and an outer pipe 2 to displace a fluid such as salt water through a pipe 4 and a further pipe 5, disposed concentrically to pipe 4, allows the passage of a small quantity of fluid to displace any salt water therein through pipe 8, control device 14, flowmeter 12 and a valve 11. The entry of fluid to the cavity 1 can be accurately determined by the meter 12 since the volume of passage 6 is known. If the flow through pipe 1 is kept constant the flow through meter 12 will vary with the cavity cross-section and hence the instrument can be used as a displacement meter.

Filed: 1973-03-13
Abstract: 1429891 Decoding bar codes MONARCH MARKING SYSTEMS Inc 13 March 1973 [29 March 1972] 12088/73 Heading G4M Markings (Fig. 3) on a record are arranged to be black bars B or white spaces S each of two nominal widths with the smaller widths representing "0" and the larger widths "1". An optical reader, which may be hand-held, scans the record for a start code. Counts corresponding to the widths of the first three areas are stored in counters 28, 30, 32 and counters 34, 36 store a value representing the width of the bar stored in counter 32, i.e., the third area B2 multiplied or divided by a constant 1À6 respectively. The code shown in Fig. 3 is arranged to have only one "1" in the spaces S and only one "1" in the bars B and successive bars are compared with each other. The contents of store 28 are fed to adders 40, 42 and compared with the contents of counters 34. If B1 < (B3/K) then relation A is obtained. If B1 > K.B3 relation B is obtained. If K.B3 > B1 > (B3/K) then relation C is obtained. The remaining B and S marks are similarly compared and a word of A's, B's and C's is obtained. This word can be fed to a read-only store to decode the whole word into binary digits or each digit can be decoded as it is obtained. Fig. 3 would produce C A C B A. Certain combinations cannot exist, e.g. A-A for the code shown but would occur due to variations in area width. The decoder would correct such misreadings. A parity checker determines that there is only one S "1" and one B "1". Start and end characters determine which way round the record is being read. A further code (Fig. 2, not shown) is described in which adjacent areas are compared. A more detailed description of the circuit of Fig. 1 is provided.

Title: Improvements relating to roller bearings
IPC: B61F15/16
Filed: 1938-04-22
Abstract: 500,015. Bearings ; locking nuts. PERCIVAL, S. (Heinze Development Co.) April 22, 1938, No. 12114. [Class 12 (i)] [Also in Group XXV] In a roller bearing the rollers 23 make contact at one zone with one race and at spaced apart zones 22, 24a, with the other race so that they deflect upon loading and the load is distributed over more than one roller. Means are provided to limit the deflection of the rollers. The rollers may be of a single diameter or shaped as shown, and the race tracks 22, 24a may be convex. As shown in Fig. 2, the outer race ring 21 has an annular projection 17a seated in the housing 15, and tracks for ball thrust bearings 22a. These latter have initial radial clearance to permit predetermined deflection of the rollers; when this deflection is exceeded the ball bearings take some of the radial load and further roller deflection is impossible. End movement of the rollers is prevented by members 23a. The housing comprises a pair of members 16, 16, secured together by bolts 17, the upper portion having an oil well 18 and lubricating ducts 20 to the bearing.

Title: Improvements in the over-speed protection of power systems
IPC: H02P9/02
Filed: 1943-07-26
Abstract: 566,992. Electric control systems. GENERAL ELECTRIC CO., Ltd., ABBOTT, A., GARRARD, C. J. O., and FRIEDLANDER, E. July 26, 1943, Nos. 12116 and 15981. [Class 40 (i)] [Also in Groups XXVI and XXXVII] The load on a prime mover and the supply of working fluid thereto are caused to move a balancing means in opposite directions ; movement caused by relative excess of supply effects a reduction to prevent over-speeding and movement in the opposite direction may in some cases be caused to increase the supply. In the apparatus shown, a wattmeter 9 measuring the power dissipated in the (electrical) load drives a sun-wheel 1, while a second sun-wheel 2 is driven by a wattmeter fed from an independent supply, the current coil of which is fed through a rheostat 19 controlled by the fluid supply of the prime mover ; the independent electric supply may also serve the relay 14 operating the throttle. The two sun-wheels drive planetwheels 3 when the speeds of the sun-wheels are caused to differ by disparity between load and fluid supply, and so centrifugally close contacts 7, 8 to energize the relay which reduces the fluid supply both when the load is relatively too high and too low. In another form, two resistances of a Wheatstone bridge are varied in accordance with the load and the fluid supply, and the out-of-balance current operates a relay to increase or decrease the fluid supply. In a third form, a wattmeter relay is fed by a current decreasing with the load and a second current controlled by a variable resistance dependent on the fluid supply, the moving coil closing contacts to control the fluid supply. In a fourth form, the load and fluid supply act on two levers connected by a link the midpoint of which carries an electrical contact which can close a circuit to reduce the supply. Specification 501,969, [Group XXXVII], is referred to.

Filed: 1937-05-01
Abstract: 498,511. Cathode-ray tubes. KLEMPERER, O. May 1, 1937, No. 12480. [Class 39 (i)] To deflect an electron beam it is so directed towards an electrode or an electrode system that it is " effectively reflected," i.e. the electrons are first decelerated and then accelerated in the reverse direction, and the deflection is varied by altering the potential, or relative potentials, of the deflecting electrodes. The Figure shows an arrangement in which the beam projected from the "gun" 3 is reflected at an equipotential surface formed by electrodes 4, 5 and the angle of incidence, and therefore the deflection, is varied by altering the relative potentials of the electrodes. An arrangement similar to one described in Specification 465,144, in which the reflecting equipotential surfaces are cylinders surrounding a straight electrode is also described. Specifications 420,752, 444,471, 469,419, and 471,250 also are referred to. Reference has been directed by the Comptroller to Specification 465,144.
