Title: Improvements in or relating to electric clocks
IPC: G04C3/06
Filed: 1928-03-17
Abstract: 300,992. Conrad, F. March 17, 1927, [Convention date]. Divided on 287,182. Electric clocks; balances and pendulums, regulating electrically; actuation by condensers; going trains.-In a clock in which the balance is electrically maintained in oscillation by electromagnets, the driving connection between the balance device and the motion work for the hands consists of right and left hand screw-threads on the balance staff which drive a wheel of the motionwork unidirectionally. An irreversible worm drive is also included so that the hands may be adjusted without interfering with the balance. The balance staff 1 carries a balance spring 2 anchored at 3, a balance wheel 5 having upright flanges 6, 7 and cut out portions 8, 9 and members 17, 18; these members 17, 18 are of opposite screwthread, extend partially round the staff 1, and drive the wheel 21 unidirectionally. The ends 48, 51, 52, 53 of the flanges 6, 7 co-act magnetically with the poles 13, 14 of the magnets 11, 12. Pins 40, 41, which also constitute the curb-pins, are adapted to close the electric circuit through the spring 2. As it expands this spring meets contact 40, energizing the magnets and charging the condenser 44. The magnets thereby assist the balance to oscillate in the direction in which it was travelling when electric contact was made. When the spring contracts it touches contact 41 and discharges the condenser through the magnets, again giving an impulse to the balance, but this time in the reverse direction. At the oscillations of the staff 1 the screw-threads 17, 18 alternately engage the wheel 21 and drive it always in the same direction. This wheel 21 drives shaft 22. worm 23, and gearing 24 - - 28, the end 31 of shaft 28 carrying the minute hand. The hour hand is on a sleeve 37 which carries a wheel 36 and is loose on shaft 28, a wheel 32 rigid with shaft 28 driving the gearing 33 - - 36. In the construction shown in Fig. 2, the members 17, 18 have grooves 90 and inclined faces 91, 92 which actuate alternately the teeth of the wheel 21. When either face 91 or 92 is actuating a tooth, the adjacent teeth pass freely through the circumferential gap in the other member. In a further construction, Fig. 4, the members have offset ends 95 and are pressed firmly upon the shaft; the operation being as in the previous construction. Specification 287,182 is referred to.

Filed: 1963-08-30
Abstract: 1,027,146. Photographic silver halide emulsions. AGFA A.G. Aug. 30, 1963 [Sept. 1,1962], No. 34423/63. Heading G2C. The invention relates to a process of preparing a photographic emulsion comprising grains composed of a silver halide core which either has its surface modified and is then coated with a shell of the same or a different silver halide, or is coated directly with a shell of a different silver halide. The emulsions are prepared by adding to an aqueous gelatine solution an aqueous solution of a water-soluble silver salt and an aqueous solution of a water-soluble alkali metal halide in such a manner that the silver ion concentration is kept between 1 x 10-6 and 1 x 10<SP>-10</SP> moles per litre in order to precipitate a maximum number of silver halide nuclei. The surface of the nuclei are then modified, if desired, and the outer shell of silver halide is formed by continuing the addition of the silver salt solution and the same or different alkali-metal halide solution. The surface of the silver halide core may be modified by one of the following treatments,- (i) Reduction of silver ions in the surface to silver atoms by means of a reducing agent such as hydrazine and its derivatives, polyhydroxy benzene compounds, ascorbic acid or formaldehyde. (ii) conversion of the surface silver halide to silver sulphide by means of sodium thiosulphate, sodium sulphide or thiourea. (iii) Incorporating gold, thallium, copper , palladium, iridium or platinum into the surface by treatment with aqueous solutions of their compounds. (iv) Exposing the emulsion in the liquid state to actinic light to form silver atoms in the surface of the core. (v) Treatment with an aqueous solution of a silver halide solvent such as a thiocyanate to cause etching of the surface.

Title: Improvements in or relating to apparatus for treatment by means of high frequency electromagnetic waves
IPC: A61N1/40
Filed: 1935-12-13
Abstract: <PICT:0467502/III/1> In high-frequency apparatus for killing bacteria in materials, two or more pairs of electrodes, each pair connected to a separate frequency-determining circuit, are disposed about the body, and means is provided for continuously changing the phase relation between the pairs of electrodes.  In one form of the invention, the frequency-determining circuits are connected to spark-gaps themselves connected in parallel through high-frequency chokes and energized from an oscillation circuit connected to the secondary of a mains transformer, the irregularity of the spark discharges producing the desired phase relation change.  In another form, two back-coupled thermionic valve oscillating circuits are connected in parallel to the secondary of a mains transformer and are coupled with the tuned electrode circuits, the oscillators being tuned to, or modulated by, different frequencies to produce the phase-relation change; the anode lead of one oscillator embodies a high-frequency choke preventing interchange of energy between the oscillators.  As shown, two or more valve oscillators such as 1, 2, coupled as at 5, 6 to tuned electrode circuits 7, 8, have their anodes connected in rapid succession to a source of positive potential such that only one oscillator is energized at any instant, with two oscillators the potential source may be the secondary of a mains transformer 3 to the opposite ends of which the oscillators are connected.  In all modifications the electrode and supply arrangements permit concentration of treatment energy at any desired point in the body or material whilst avoiding surface effects.  In addition, with the circuit shown the output circuits may be used independently, or simultaneously for low-power treatment of two independent bodies or materials, or in parallel for single high-power treatments.  The Provisional Specification illustrates four pairs of electrodes connected to separate generators, the electrode being arranged side by side on opposite sides of an elongated body to effect treatment over a large area.  Specification 315,367, [Class 1 (i)], is referred to.

Title: Process for the treatment of yarns and textile piece-goods
IPC: D06B21/02
Filed: 1957-11-07
Abstract: <PICT:0854221/IV (c)/1> In the wet-processing of yarns or textile piece goods, the material to be treated is tightly wound in a layer on a rotatable cylindrical hollow body the cylindrical wall of which is provided with a large number of openings for the passage of the treating liquid, and the said liquid is introduced into the interior of the cylindrical body while the latter is rotating on a horizontal axis and at a sufficient speed to expel the liquid by centrifugal force from the cylindrical body and through the layer of material to be treated.  Preferably, the cylindrical hollow body has closed end walls.  As shown, a cylindrical hollow body 1, rotatably supported, has a perforated cylindrical wall 12, and preferably has closed end walls 13.  Treating liquid from storage vessel 7 passes through conduit 8 and the perforated conduit 2, which is either rigidly connected to 1 or so supported as not to rotate, and hence through the layer of material wound on 1, which rotates within the stationary enclosing vessel 3.  Liquid running down the walls of the enclosing vessel is returned via collector 4, pump 5 and conduit 6 to storage vessel 7, or part of this liquid may be recycled directly to the cylindrical body via a collector. If an open-ended cylindrical body is used, and the quantity of treating liquid is sufficient to rise above the bottom wall of the perforated cylinder 12, the pump system may be omitted, since liquid will enter the cylinder by itself.  As shown in Fig. III, conduit 2 may be replaced by a distributer comprising 2-4 branch conduits 14 which may or may not rotate with cylinder 1. Materials of, e.g., wool, cotton, linen, silk, rayon and synthetic fibres may be subjected to successive treatments, e.g. washing, rinsing, dyeing and rinsing, while wound on the cylindrical body.

Title: Improvements relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1920-12-10
Abstract: 155,257. Sperry Gyroscope Co., (Assignees of Tanner, H. L.). Dec. 15, 1919, [Convention date]. Gyroscopic compasses.-The readings of a gyro-compass are corrected for latitude and velocity of the ship &c. by means which automatically displace the lubber ring to correct for the course, and which are adjusted to produce the further displacements required to correct for speed and latitude by a single actuation of a movable indicator. In the construction shown in Figs. 1, 2, and 3, the card 2 carries an inclined cosine ring 5 co-operating with a roller 8 at the end of an arm 10 secured to a spindle 11 mounted in a bracket 12 secured to the spider 1. Also secured to the spindle 11 is an arm 13 having a slot 14 through which passes a pin 18 which also passes through a slot 17 in an extension 15 of an arm 16. The arm 16 has bifurcations 19, 20 attached by vertical pivots 21, 22 to a member 23 secured to the lubber ring 3. The displacements of the roller 8 due to change of course are thus converted into displacements of the ring 3. The further corrections for latitude and speed are effected by adjusting the position of the pin 18. The pin 18 passes through a block 29 carried in the bifurcated end 28 of an arm 27 the other end of which is formed with a tongue passing through a slotted enlargement 30 on a spindle 31 carried by the member 23. Also secured to the spindle is an arm 32 which can be displaced by a screw 37 actuated by a milled head 38. The arm 32 has an extension 33 bearing a latitude scale, and speed curves 40 are provided on the top of the member 23. The head 38 is turned until the appropriate latitude graduation intersects the appropriate speed curve. In a modification the movements of the roller 8 impart motion to a lever, the outer end of which operates a device secured to the lubber ring, and the fulcrum of the lever is manually adjusted to correct for latitude and speed. In a further modification, the ring 5 is dispensed with and the usual gear ring carried by the card actuates, through tooth and worm gear, a shaft which is mounted in bearings carried by the spider and in which is pivoted a disk the edge of which engages in a fork member secured to the lubber ring. The inclination of the disk to the shaft is adjusted by connecting it to a collar which is mounted on the shaft and can be adiusted longitudinally thereon, bv means of a milled head, in accordance with latitude and speed. Specification 15679/11 is referred to.
