Title: Arrangements for measuring distance between two objects particularly for depth sounding
IPC: G01S15/34
Filed: 1939-06-09
Abstract: 530,326. Echo-sounding apparatus. STANDARD TELEPHONES & CABLES, Ltd., and HINTON, L. T. June 9, 1939, No. 16973. [Class 118 (ii)] In apparatus particularly for measuring the depth of the sea, a sound wave is emitted of which the frequency is cyclically varied between limits, and the frequency of the wave received after reflection from the sea-bed is compared with that of the wave then being emitted, the difference being measured to indicate the depth. The sound emitter T which is suitably disposed within a directive horn H comprises a central magnet A having on either side pole pieces P1, P2 which operate on diaphragms D1, D2 and carry windings fed from an electric oscillator S. The latter includes a variable condenser which is constantly driven by a motor M. The sound receiver W is similar to the emitter and is similarly located within a horn, and feeds a frequency detector R which controls an indicator 1. The units T, W are preferably mounted on opposite sides of a ship so that the shadow effect of the hull attenuates the sound received directly by the receiver W. In any event, it may be arranged for the oscillator S to feed the detector R directly over wires. The frequency detector may take the form of a modulator from which the difference frequency is separated by a filter and taken through an amplitude-limiter to a resonant circuit, which has a linear impedance-frequency characteristic over the range to be measured. The output is rectified and applied to a meter which may be calibrated to give the depth directly. To obtain greater accuracy, the depths to be measured may be divided into ranges, and the period of the frequency cycle is then suitably chosen for each range by a 3-speed gear associated with the motor M. The operating lever of the gear may control a switch which causes the illumination of one of three meter scales. A recording meter may also be employed.

Title: Improvements in or relating to aircraft cameras for taking pictures bearing an image defining the position of the nadir point
IPC: G03B17/56
Filed: 1953-06-19
Abstract: 736,830. Photographic cameras. NISTRI, U. June 19, 1953 [June 20, 1952], No. 17031/53. Class 98 (1). A camera for use in planimetric air photography includes means whereby recordings are made on the photogram plane which can be used to evaluate the angular inclination of the camera axis at the time of exposure. As shown in Fig. 2, the camera has an objective b with principal axis PS which is perpendicular to the plane 4 of the photogram when the aircraft carrying the camera is in level flight. Gyroscopes O<SP>1</SP>   and O<SP>11</SP> are provided with their primary axes orthogonal; each axis is parallel to the plane 4 and in a common plane with the axis PS which common planes respectively intersect the plane 4 in lines X and Y meeting at the centre P of the photogram. A prism 21 (or 2<SP>11</SP>) is attached to each primary axis and reflects into a lens 6<SP>1</SP> (or 6<SP>11</SP>) light from a collimator 31 (or 3<SP>11</SP>) so that this lens images on the photogram a grid disposed in the light path in the collimator. Thus grid images N<SP>1</SP> and N<SP>11</SP> are formed on the photogram in positions dependent upon the degree of tilt of the camera axis PS at the time of exposure; the intersection N of lines drawn through these images parallel to the axes X and Y respectively represents the nadir point, the distance PN being the nadir distance. In a modification, a universal mounted pendulum is combined with the collimator and explores the gyroscopes. Another form is described in which the collimator is carried by a universal mounting which is eccentrically controlled by a gyroscope. Specification 669,959 is referred to.

Abstract: 204,680. Barnes, F. A. Sept. 29, 1922, [Convention date]. Washing-machines with plungers and dollies having both rotary and axially-reciprocating motion. - In a machine having plungers 101 reciprocated vertically and given a step-bystep rotary motion in the tub 94, the driving-mechanism for the plungers and for a vertical shaft 23, Fig. 1, to which a wringer may be coupled, is enclosed in a housing 10 formed integrally with legs 19, 82. The vertical reciprocation is derived from a cam plate 29, Fig. 1, and the step-by-step rotary motion from a Geneva-stop mechanism 37, 39, 47. The wringer shaft is driven from a worm 77, Fig. 3, on a shaft 74 connected to an electric motor 66 through a coupling 75 adapted to yield under excessive load, and the cam shaft 27 is driven from another worm 76 through a handoperated clutch 31, Fig. 1. Lubricant is circulated within the housing by a rotary impeller 118, Fig. 3, at the end of the motor-driven shaft. The camshaft 27 is hollow and supported by a post 26 screwed into a depending boss 25 of the housing. The sleeve 31 of the clutch is provided with pins 35 adapted to engage holes in the web of a worm wheel 33 gearing with the worm 76, and is shifted by means of a forked lever 107 operated by an inclined arm 110. This arm 110 has rack teeth engaging teeth on an upright pull rod 112, Fig. 2, passing through one of the hollow parts 91 of the tub, and may be retained in its set positions by a ball and socket catch 116, 114. The plunger-rod 51 is mounted in a part-cylindrical recess 40 of the housing, and is provided with collars 52, 58 between which is mounted a loose sleeve 54 carrying a roll 56 engaging the cam track. The sleeve 54 and the upper collars 58 have ribs engaging longitudinal grooves 42 in the recess, serving to prevent rotation of the plungers during their stroke. Attached to the Geneva wheel 47 is an internally ribbed hub 46, which imparts limited rotation to the collar 58 and therefore to the plungers when the collar enters the hub at the end of the up-stroke, the Geneva wheel being advanced at this moment. The plungers are carried by a rod screwed to the rod 51 and passing through a stuffing-box 102 in a tubular post 96. A washer 103 is mounted at the joint on the rod 51, and flanges of the stuffing-box 59 on the housing serve to deflect water leakage outside the housing. A cover-plate 84 is bolted to a flange 14 of the housing 19 and to radial arms 81 extending from the housing, and posts 90, 91 carried by the cover-plate support a top ring 93 of the tub. The rotary impeller 118 draws lubricant from the bottom of the housing through a pipe 121, Fig. 3, and discharges it through a pipe 122, which may have perforations along it to supply oil to the. worm 77. The packing ring 67 between the motor and the housing is of insulating material and is formed with an inwardly projecting part 67<a> serving to prevent access of oil to the motor.

Title: Process for the regeneration of double-skeleton catalyst electrodes
IPC: B01J23/94
Filed: 1958-05-30
Abstract: Double skeleton catalyst electrodes as described in Specification 806,644 and comprising a supporting skeleton of iron, nickel, or silver and, embedded therein, a skeleton of porous Raney metal comprising iron, cobalt, nickel or silver are regenerated, when exhausted, by a process involving three steps. In the first step the electrode is treated with a boiling alkaline solution, e.g. 6N potassium hydroxide, to remove silica and aluminium hydroxide, or alternatively the solution may be forced through the electrode pores. In the second step, oxides and hydroxides of iron, nickel, cobalt and copper are removed by treatment in alkaline solution, e.g. potassium hydroxide of pH9-12, at a temperature between 50 DEG C. and the boiling point of the solution, which may contain 5%-40% of citric or tartaric or their salts, e.g. potassium sodium tartrate, or ethylene diamine tetracetic acid or its salts, or nitrilotriacetic acid or its salts.  An alternating current of 200 ma. may be passed through the electrode during this step.  In the third step the electrode is made a cathode in a solution as in the first step, whereby silver chloride and oxides and sulphides of iron, nickel, copper and silver are reduced, a nickel or platinum plate serving as anode.  The regenerated electrode is kept in a reducing atmosphere.

Title: Improvements in electric excess supply meters
IPC: G01R11/60
Filed: 1928-06-14
Abstract: 292,166. Telefon-Aktiebolaget L. M. Ericsson, (Assignees of Jacobsson, F. M., and Ljungdahl, X. G.). June 16, 1927, [Convention date]. Integrating. - A meter in which one or more excess supply counters register the supply above predetermined limits is provided in addition with a total supply counter, all the counters being driven from the same source, of power. The meter 1 is provided with a contact which sends through an operating-magnet 8 a number of impulses during a predetermined time interval proportional to the energy used in that interval. The magnet 8 operates, through an armature 5, a counter registering the total supply, and also closes a contact 24 in the circuit operating- magnets 2, 3, 4 which actuate counters registering the excess supply above three corresponding limits. The magnet 8 also advances, in a clockwise direction, a ratchet-wheel 9 which is periodically returned to its starting position periodically by means of an electromagnet 15 controlled by a clockwork 16. The ratchet-wheel 9 carries a pin 13 which closes in succession switches 18, 19, 20 in the circuits of the magnets 2, 3, 4, which are thus brought into operation after three separate limits of consumption within the predetermined period. The switches 18, 19, 20 are adjustable along the periphery of the wheel 9 into different positions in relation to the starting position of the wheel in order to vary the supply limits. Alternatively the excess counter may be arranged to register supply between certain limits by causing the switch 18 to be opened on closing the switch 19, which is opened on closure of the switch 20. The wheel 9 may alternatively be driven by gearing from the meter 1. The counters may also be mechanically driven, for example, by means of gearing from the wheel 9.

Abstract: 845,948. Combing machines. RIETER & CIE A. G., J. J. May 30, 1958 [June 1, 1957], No. 17376/58. Class 120(1). -- In a rectilinear combing machine having a swinging upper mechanism, movement is imparted to the feed roller by the relative movement of the top and bottom nippers 13 and 3. Arms 12 carrying the top nipper 12 are pivoted to the bottom nipper by pins 15. A gear segment 61 is freely mounted on one pin 15 and is biassed by a spring 72 so that one end 75 of the segment abuts against the arm 12. The segment meshes with a gear 63 freely mounted on the end of the feed roller and driving the roller via a ratchet and-pawl mechanism, whereby the roller is rotated by the closing movement of the nippers. Manual feeding is effected by moving a protuberance 70 of segment 61 counter-clockwise against the action of spring 74. To remove the feed roller, the joint at a pin 73 between arm 12 and a link 21 is depressed past a dead centre position so that a pin 77 on arm 12 engages the hooked end of a spring 40 and pulls the spring away from a roller-retaining position; the roller can then be lifted clear of the bottom nipper 3, together with gear 63 and the ratchet mechanism.
