Title: Process for the manufacture of lactones of 3-keto-acids of the sugar series
IPC: C07D307/62
Filed: 1934-03-24
Abstract: Lactones of 3-keto acids of the sugar series are prepared by treating osones derived from the next lower sugar with hydrocyanic acid and saponifying the products.  The osones, obtained by oxidation of sugars in the usual way, or the hydrocyanic acid may be used in the form of salts or of decomposable addition products, whilst small amounts of basic substances may be used to accelerate the acid treatment.  The reaction must be effected in the absence of air and oxidizing agents.  According to the example, d-xylosone is dissolved in aqueous hydrocyanic acid, a little ammonia added, and allowed to stand for a day in an atmosphere of carbon dioxide; after evaporating to dryness, the product is heated with dilute hydrochloric acid in a carbon dioxide atmosphere and again evaporated to dryness; the resulting d-ascorbic acid is purified by means of its lead salt or acetone compound.  From l-xylosone, l-ascorbic acid is obtained in the same way.  The sample consists of the lactone of d-arabino-3-ketoheptonic acid prepared by interaction of d-glucosone and sodium cyanide, followed by saponification with hydrochloric acid and purification with barium carbonate.

Title: Process for coating vitreous surfaces with powdered luminescent materials
IPC: C09K11/02
Filed: 1948-04-02
Abstract: 669,392. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd., ANDERSON, J. T., and WARD, H. F. April 29, 1949 [April 2, 1948], No. 9356/48. Class 39 (i). Process for coating a vitreous surface, e.g. a fluorescent lamp tube, with powdered luminescent material comprises coating the surface with a suspension of the material in a water solution of an organic material (other than ammonium alginate) which is capable of giving at least moderately viscous solutions and which, when heated to a decomposition temperature, leaves only a small or no residual ash, and thereafter heating the coating so formed to a temperature at which decomposition takes place. The water-soluble organic material may consist of water-soluble starch or a watersoluble cellulose such as methyl cellulose or glycoll cellulose or the water-soluble variety of " Cellophas " or a salt of alginic acid (other than ammonium alginate) such as triethanolamine alginate. A wetting agent such as that known under the Registered Trade Mark " Teepol X " which leaves no deleterious residuum after the heating to the decomposition temperature may be added to the suspension of the luminescent material. In cases where the luminescent material is readily wet by water the material may either be previously wetted with water containing the wetting agent, the material being subsequently thoroughly washed with successive lots of distilled water to remove substantially the whole of the wetting agent,'or the material may be immersed, with or without agitating, in water. The wetted powder is then added to the binder without intermediate drying. The process is applicable both to luminescent materials which are not readily soluble in water and to luminescent materials which are readily soluble in, or attacked by, water, if the process is carried out sufficiently quickly to ensure that the period of contact of the material with water is restricted.

Title: Improvements in forming sheet glass
IPC: C03B17/06
Filed: 1925-04-08
Abstract: 242,167. Marks, E. C. R., (Libbey-Owens Sheet Glass Co.). April 8, 1925. Drawing.-A method of forming sheet glass consists in flowing glass downwardly from a container through a slot having restricted end portions, and providing for a freer flow of the glass above the restricted ends than of that above the wider central portion of the slot. The slot is formed in a refractory block 4 which is arranged in the bottom of a shallow flowing-tank or forehearth 3. Glass flows through the slot and forms a sheet 12 which passes between coolers 11 into an annealing chamber 14. The central portion 6, Fig. 3, of the slot is considerably wider than the thickness of the sheet to be produced and the walls 7 of the slot extend vertically upwards for several inches and then curve outwardly. The short end portions 9 of the slot are narrower than the central portion 6, and the part of the block above the narrow ends is hollowed out to form receptacles 10, Fig. 1. The receptacles 10 provide a large body of relatively hot glass above the narrow ends 9 of the slot. The vertical walls 7 above the wider portion 6 of the slot cause the glass to flow more slowly into the central portion of the sheet.

Title: Winding control mechanism
IPC: H01F41/08
Filed: 1952-04-15
Abstract: 704,229. Coiling. AUTOMATIC ELECTRIC LABORATORIES, Inc. April 15, 1952 [May 29, 1951], No. 9443/52. Class 83 (4). [Also in Group XXXVI] Machines for winding toroidal inductors are provided with means for continuously supervising the inductance of the coil as it is wound on the core in such a manner that as the final desired inductance is approached the effect of the wire remaining on the shuttle is minimized, and when the winding is complete a substantially exact value of inductance is attained. A rotating shuttle 1, Fig. 1, mounted on idlers 5 interlinks the toroidal core 3 to be wound and has a transverse joint 7 which is normally secured closed by means of an insulator. The wire 9 is first wound on the shuttle in a counterclockwise direction and is unwound on to the core 3 in a clockwise direction. The wire 9 is passed over a wire guide and tension device 11. Resilient arms 15 are biased by a spring 12 slidably movable along a slot 13 so as to control the tension applied to the shuttle periphery. One end 18 of the wire 9 is connected through a standard condenser 19 to a terminal 21, the other end of the wire being connected to the shuttle 1, contact with which is made by a spring contactor 27 connected to a terminal 29. A cathode ray oscilloscope 30, Fig. 2, has vertical and horizontal deflecting plates 31, 36 connected to amplifiers 43, 40, the opposite plates 33, 34 being earthed. A signal generator 37 is connected through a phase shifter 39 to the horizontal amplifier 40 and is also connected through ganged switches 23, 38 to the vertical amplifier 43. A variable calibrating resistor B is in series with the ganged switches 23, 38 and the signal generator 37 and a second variable calibrating resistor A is connected between terminals 41, 42 of these switches. The other switch terminals 29, 21 are connected by the winding circuit as shown in Fig. 1. The capacitance of the condenser 19 is so chosen that when the required number of turns has been wound on the core 3 resonance occurs and a straight line trace 44 appears on the oscilloscope 30. Fig. 3 is a slide elevation of a portion of the shuttle 1 containing the transverse joint 7 which is provided to permit lateral movement of the two ends of the shuttle ring so that it may be passed through the toroidal core. In order to insulate the gap and also to provide rigidity in the ring, an insulator 47, conforming to the curvature of the shuttle but having lobes at each end, is fitted into a conforming recess in one flange of the shuttle. In the periphery of the shuttle is a circular recess into which is fitted a disc insulator 51, Fig. 4. The two insulators 47, 51 prevent radial, tangential, or transverse movement of the ring in the vicinity of the joint 7.

Abstract: 760,977. Rotary spherical valves. ENGLISH ELECTRIC CO., Ltd. March 25, 1955 [April 1, 1954], No. 9559/54. Class 135. A hydraulic discharge regulator comprises a part spherical cap 3 attached by lateral cheeks 5 to trunnions 6 transverse to the axis of the discharge pipe 1 to form a gate which can be swung in front of the pipe or moved completely clear thereof, the cap being provided on that part of its edge which is the leading edge in the opening movement with a deflector 9 pointing back towards the discharge pipe in the closed position of the gate, the deflector together with the cheeks giving the gate a scoop-like shape. A concave machined seating face 4 co-operates with a seating ring 2 machined convex about a centre 0 on the axis of the pipe 1. The trunnions 6 however are offset from the axis of the pipe so that as the gate is opened by a rod 8 articulated to an arm 7 the seating face moves clear of the ring 2. The pipe 1 contains a stream-lined hub member 10 joined to the pipe by stream-lined vanes 11 inclined to the axis of the pipe. The vanes may be shortened and the hub member dispensed with. In another modification, the stream issuing from the pipe 1 is broken up and aerated by radial fins or teeth inside the exit of the pipe. In a further modification, the cheeks 5 are supported on crank pins 15, Fig. 5, supported by trunnions 16 offset from the axis of the pipe. The pins 15 are first moved from a point coincident with the centre of curvature of the face 4 by a separate lever 17 and the gate, having being lifted slightly from its seat, is subsequently turned by its operating link 18. In a similar arrangement, the crank-pins are replaced by eccentrics on which the cheeks are pivoted. The trunnions of the gate may be mounted in parallel slides shiftable in the direction of the axis of the pipe. The metal seating ring may be replaced by an inflatable ring. Fig. 1 (Comp), shows a further modification in which the gate 3 is provided with spaced valances 31 supported by ribs or webs 31, 32. These valances prevent the lateral spreading of the jet of water as the gate is closed..

Title: Process and device for adjusting radial and tangential angles of light beams
Inventor: FUELDNER FRIEDRICH
IPC: G11B7/095
Filed: 1995-06-29
Abstract: A process is disclosed for measuring or adjusting the radial and tangential angles of a light beam. In an optic reproduction device, such as a CD player, care must be taken that the data scanning light beam irradiates the disk as normal as possible. Because of the disk warp, however, the radial and tangential angles of the light beam change with each turn of the disk. Because of disk and device tolerances, the optical axis usually deviates from the normal. During reproduction, these deviations change. EP-PS 0 070 070 describes a costly optic measurement device to adjust the radial and tangential angles with respect to a fixed axis. In order to adjust the radial angle R and the tangential angle T of incidence of the light beam on the disk without additional measurement devices, the data signal (HF) is demodulated in an amplitude demodulator (DM). The adjustment signal UR = C * sin $g(f) * cos $g(a) for the radial angle R and the adjustment signal UT = - C * cos $g(f) * sin $(a) for the tangential angle T are derived from the amplitude C and the phase relation $g(f) of the demodulated data signal (M). The invention has applications in optic reproduction devices such as CD players, vido disk players and DRAW disk players, or in magneto-optic recording and reproduction devices.
