IPC: H05B41/24
Filed: 1933-03-14
Abstract: 417,855. Discharge lamps. PINTSCH AKT.-GES., J., 71, Andreasstrasse, Berlin. March 14, 1933, No. 7772. Convention date, May 6, 1932. [Class 39 (i).] A lamp is excited by a highfrequency field (above 10<6> Hertz) and the intensity of illumination is controlled by an auxiliary voltage of frequency at least one decimal order lower than that of the exciting voltage, and amplitude and frequency such that its application yields a diminution in luminosity. In one form, the high-frequency is applied to two electrodes inside or outside the tube, and the auxiliary circuit consists of two internal auxiliary electrodes supplied from a separate source of current, possibly a continuous or lowfrequency alternating-current source. In a modification, one of the auxiliary electrodes is dispensed with and a low-frequency controlling source is connected to the centre point of a high frequency choke which is connected across the high-frequency source. In another modification Fig. 3, the high frequency is supplied from a source 3 through condensers 7 to the electrodes 2, and the low-frequency control is supplied to the same electrodes from a source 5 through chokes 6. In another modification the highfrequency electrodes are dispensed with and high-frequency current is passed through a coil surrounding the tube. The electrodes may consist of a cylinder and a pin coaxial therewith. For television purposes, metal strips 12, Fig. 7, may be arranged to form a cellular structure and axial pins 11 in each cell may constitute the other electrodes. The high frequency may be applied between electrodes 11 and 12 and controlling voltages between each pin 11 and the electrode 12.

Title: Braking device
IPC: B60T7/12
Filed: 1944-04-27
Abstract: 579,214. Brakes. DERUNGS, E. A. April 27, 1944, No. 7910. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 27, 1944.] [Class 103 (i)] [Also in Group XXXVII] A brake is controlled electro-magnetically in such manner that the intensity of the application and its duration is,determined by the magnitude of power input to the machine to be braked at the moment of initiation of the braking action, and by the speed of the machine at the same moment. As shown, brakes 58, 59 are applied to the motor 57 by a weight 66, the action of which is opposed by a solenoid 67. A ring 73, carried on a shaft 69 coupled by a flexible shaft 56 to the motor 57, surrounds an electromagnet 74, 76 on a shaft 77 which is movable against the action of a spring 80, the shaft carrying a contact arm 81 which moves from the contact 86 to, or towards, the contact 82 to an extent determined by the force exerted by the rotating ring 73 on the magnet 74, 76. The magnet and a solenoid 102 in series therewith are shunted across a resistance 51 in the motor circuit, so that the pull of the ring on the magnet depends upon the speed of the motor and the current taken thereby, the arm 81 assuming a corresponding position. The solenoid 67 is excited, when the motor 57 is switched off, by a circuit including the contact 104, arm 81 and impedance 106, and as the magnet 74, 76 is disengaged when the motor circuit is broken, the spring 80 is able to restore the shaft 77 and arm to the position of rest. The time taken for this rotation is determined by an adjustable escapement 92, 93, a one-way connection between the shaft 77 and the escapement permitting the angular setting movement of the shaft 77 under the influence of the ring 73. As the arm 81 moves through its timed swing over the contacts 82-86, the impedance in circuit is progressively reduced, leading to a progressive increase in the excitation of the solenoid 67 and a consequent decrease in braking pressure. The regulating device may be used to control a fluid pressure brake cylinder,

Filed: 1959-03-06
Abstract: 859,103. Television. AMPEX CORPORATION. March 6, 1959 [March 19, 1958], No. 7928/59. Drawings to Specification. Class 40(3). "Editing" pulses of field recurrence frequency are recorded on a magnetic tape on which video and synchronising information are also recorded to facilitate cutting and splicing of the tape without introducing discontinuities in the synchronizing signals. The "editing" pulses, which are derived from the field synchronizing signals and recorded in a predetermined position with respect to (preferably adjacent to) the synchronizing signals, consist of regions of magnetic saturation which may be made visible by dusting the tape with magnetic powder. The tape may then be cut, accurately, between successive fields (for which purpose suitable apparatus is described) so that, when subsequently spliced, no discontinuities occur in the recorded synchronising signals. The invention is described in connection with a recording system generally of the kind disclosed in Specifications 798,927, 798,928, 798,929 and 798,930.

Patent GB-804197-A (GB)
Title: Method for preparing fatty acid esters of oligosaccharides
IPC: C07H13/06
Filed: 1957-03-13
Abstract: Fatty acid esters of non-reducing oligosaccharides (i.e. di-, tri- and tetra-saccharides, containing from 7-16 hydroxyl groups per molecule) are prepared by reacting a non-reducing oligosaccharide with a fatty acid ester of an aliphatic primary monohydric alcohol of from 1-16 carbon atoms or of a polyhydroxy compound (as defined below) in the presence of an interesterification catalyst at 20-150 DEG  C., preferably 80-150 DEG  C., in the presence of N-formyl-, acetyl- or propionyl-morpholine or piperidine.  The term "polyhydroxy compound" includes polyhydric alcohols having from 2-6 hydroxyl groups, glycosides, and oligosaccharides having from 7-16 hydroxyl groups; these may be fully or partially esterified, specific examples being glycol dipalmitate, glycerol mono-, di- and tri-palmitate, mannitol partial palmitates, erythritol tetrapalmitate, pentaerythritol tetrapalmitate and sorbitol hexapalmitate; methyl glucoside tetrapalmitate; and sucrose octapalmitate.  Specified starting oligosaccharides are sucrose, trehalose, glucoxylose, raffinose, melezitose, gentianose and stachyose.  Suitable fatty acid esters of monohydric alcohols are those of methanol, ethanol, hexanol, decanol, dodecanol and hexanedecanol, such as methyl, dodecyl and hexadecyl palmitates.  Esters derived from fatty acids of about 8-22 carbon atoms, such as mixtures of acids obtained from animal, vegetable and marine oils, and fats, are useful.  For the preparation of oligosaccharide esters of single fatty acids, fatty acid esters of relatively volatile alcohols, e.g. up to 3 carbon atoms, and of acids having about 12 to about 22 carbon atoms are preferred.  Any basic molecular rearrangement or interesterification catalyst may be employed, such as sodium methoxide, anhydrous potassium hydroxide, sodium hydroxide, metallic sodium, sodium/potassium alloy, and quaternary ammonium bases such as trimethyl benzyl ammonium hydroxide.  The proportion of catalyst is preferably 0.05-2.0 per cent by weight of fatty acid ester. Depending on the ratio of oligosaccharide to fatty acid ester taken, the oligosaccharide may be partially or completely esterified.  The process may be carried out under reduced pressure, so as to remove liberated free alcohol.  In examples, sucrose is reacted with a cottonseed oil and soyabean oil mixture, in the presence of formyl, acetyl and propionyl morpholine, and formyl and acetyl piperidine. U.S.A. Specification 2,442,532 is referred to.
