Title: Recording apparatus with automatic cancellation
IPC: G01P1/12
Filed: 1958-12-02
Abstract: 845,839. Recording-apparatus. AMSLER, M. Dec. 2, 1958 [Dec. 10, 1957], No. 38779/58. Class 106 (4). A temporary recorder comprises a rotating drum 18 with a number, e.g. 480, of resiliently flexible tongues 58 on one rim and a stationary cylinder 3 with a rib 59 extending along the path of the free tongue tips and having an interruption, with a pilot tongue 60 in the region thereof controlled by an electromagnet 64 to occupy one of two end positions and, when occupying one such position, deflecting the tongues which travel past the interruption and causing them to slide over the rib 59 until they reach the interruption again, and when occupying the other end position permitting the tongues to travel past undeflected beneath the rib 59. The tongues are integrally formed by stamping on an annular disc 54 less than <SP>1</SP>/ 10  mm. thick, e.g. of teraphthalate foil, clamped between rings 57 together with another disc 55 extending over the roots of the tongues 58 to reduce the bending stress there when deflected in that direction. For recording speed, the drum 18 receives a one-way drive from a flexible shaft 18<SP>1</SP> in accordance with the travel of a vehicle and a switching device, in circuit with the ignition, alternately energizes and de-energizes the electromagnet 64 every half-second causing the pilot tongue 60 to deflect and leave undeflected groups of tongues 58 alternately, e.g. groups of eleven at a speed of 50 kilometers per hour. The arc of the rib 59 corresponds to a distance travelled of 300 metres and, in addition to recording speed over the last 300 metres, the operation of the horn, the lights, left and right direction indicators and the brakes can also be temporarily recorded by arranging for appropriate electric circuits to control electromagnets 64 corresponding to other banks of tongues. The casing of the instrument is transparent and light from a lamp 78 within the drum 18 is reflected on to the tongues 58 differently on the bent and unbent ones so that if they are coloured they will appear to be of different shades. A reading of the speed is obtained by releasing a brake disc with lever 85 and turning a disc 82 until the tip 81b of a hand 81 lies over the slit between a group of bent and unbent tongues 58 and then, after applying the brake to lock this hand, operating a turn-table 94 to bring the tip 88b of a hand 88 over the next such slit. The speed is then indicated by the vernier scale 98 against the speed scale 97, which have moved with the hands 81, 88 respectively. The hand 88 carries a magnifying glass over the tip 88b which can also be brought over the tip 81b when setting the hand 81 first.

Abstract: 933,768. Treating ores. D. WESTON. Nov. 17, 1959 [Jan. 21, 1959], No. 38956/59. Class 82. A reagent is applied to a finely-divided solid material by forming a pulp of the material in a first liquid and contacting the pulp with the reagent under conditions characterized by a high degree of kinetic energy, while the reagent is in the form of a dispersion of droplets which are initially immiscible with the first liquid. The method may be used for the application of reagents prior to flotation, for the treatment of magnetite with sodium silicate prior to magnetic separation and for the treatment of a material with leach liquor. The high energy condition may be produced in the contacting zone by mechanical agitation, e.g. as shown in Fig. 1, in which a conditioning tank has a rotating impeller 11 and is provided with nozzles 16 to which reagent and air are supplied by lines 17 and 18 respectively. Contacting may also be effected in the throat of a Venturi tube, in a straight walled tube or in the launder and/or drum of a wet ball mill. Alternatively, or additionally, the high energy condition may be produced by heat, pressure, ultrasonic vibrations or high-frequency electrostatic and electromagnetic fields. Fig. 9 shows a unit suitable for the treatment of a pulp with a leach liquid. The pulp in the inlet duct 92 is agitated by ultrasonic generators 95 and a dispersion of leach liquor is supplied through nozzles 96.

IPC: H05B44/00
Filed: 1957-12-23
Abstract: 903,400. Television. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 19, 1958 [Dec. 23, 1957], No. 39909/57. Class 40 (3). [Also in Group XL (a)] In an arrangement in which the distribution of illumination in a light image is converted by means of a plurality of elements of a photoconductive device into a " voltage pattern " having a similar distribution and supplied over a plurality of conductors to individual elements of an electro-luminescent device which reproduces a similar light image, each element of the latter device is connected to an adjacent pair of elements of the photo-conductive device over separate paths which include oppositely poled rectifiers or oppositely poled D.C. voltage sources the electro-luminescent and photoconductive elements and the paths being connected across a source of A.C. voltage. With this arrangement a D.C. operating potential is effective during successive half-cycles of the A.C. supply on one or other of the adjacent photo-conductive elements and since these are subjected to substantially the same light stimulus the electro-luminescent element connected thereto reproduces this light value during each half cycle of the A.C. supply. Fig. 1 shows one of the above arrangements in which oppositely poled voltage sources 13, 14 are connected to electrodes 10, 11 associated with two adjacent elements of a photo-conductive device 9 on which the light image is directed. Each of the pairs of elements has a second common electrode 15 connected over individual conductors 5 to individual electrodes 3<SP>1</SP> associated with a plurality of elements in an electroluminescent device 1, the other common electrode 3 of which is connected to one side of an A.C. source, the other side of which is connected to the D.C. sources 13, 14. By making the voltage of the latter equal to the peak value of one half cycle of that of the A.C. source, the latter may have twice the normal value with a consequent increase in the light output of device 1. If, in the embodiment of Fig. 1, the plurality of conductors 5 are combined in a single cable " cross-talk " between the different circuits results due to capacity coupling effects. To eliminate this, the arrangement shown in Fig. 2 in which separate conductors A and B and separate D.C. sources (in this case provided by rectifiers 19) are provided for each element is employed the conductors A and B being formed in separate common cables which are kept at a considerable distance apart. Specification 726,406 is referred to.
