Title: Method of production of alginic acid esters from seaweed
Filed: 1934-01-22
Abstract: The jelly-like substance containing a large quantity of alginate, which may be obtained from seaweed by extracting laminaria with a sodium carbonate solution containing ammonia and other salts, filtering, acidifying with a mixed nitric and hydrochloric acid to precipitate re-dissolving in ammonia solution and drying in transparent sheets, is converted into nitric or acetic esters by treatment with mixed sulphuric and nitric acids or with mixed sulphuric acid and acetic anhydride.  Examples are given of the conversion of the gelatinous substance containing alginate obtained from brown alga into an "algin nitric ester" and an acetic ester, products which are comparable with nitro- and acetylcellulose, respectively; the former product is suitable for the manufacture of celluloid.

Title: Improvements in or relating to devices for generating high-frequency electrical oscillations
IPC: H05B6/04
Filed: 1948-01-27
Abstract: 643,909. Automatic power control systems. PHILIPS ELECTRICAL, Ltd. Jan. 27, 1948, No. 2460. Convention date, Jan. 30, 1947. Drawings to Specification. [Class 38 (iv)] [Also in Group XL (c)] In a generator of high-frequency radiation of high power comprising a.periodically ignited gas discharge tube which energizes an oscillatory circuit, a control voltage is derived dependent on the output power and reacts on the ignition frequency generator so that variations in the output are counteracted. The discharge tube is of the spark discharge or capacitively fired mercury vapour type and a resistor in its cathode circuit connected to a smoothing filter measures the average current and therefore power consumed by the tube as a voltage drop across the resistor which is applied to the control grid of a pentode valve acting to charge a condenser periodically to a negative voltage firing a thyratron. Negative variable frequency pulses are produced and applied momentarily to interrupt the anode current of a further valve with resonant anode coil, the high developed voltage across which fires the discharge tube. The mercury arc is extinguished as soon as the discharge tube anode voltage passes through zero during the oscillation initiated in the anode circuit.

Filed: 1975-01-21
Abstract: 1502642 Data collection AZURDATA Inc 21 Jan 1975 [22 Jan 1974] 2584/75 Heading G4A A portable data collection device includes a keyboard, a memory into which data is entered from the keyboard, and a display 1002. The data is arranged in blocks each block being identified by a header formed of a header symbol "L" and a plurality of characters forming one or more lines; each block includes one or more lines of source data characters. The memory is formed by a temporary memory and a main memory, each formed by recirculating shift registers, the characters of each line of header information or source data being entered into the temporary memory and being displayed, for verification, on the display 1002 by the double actuation of an "IND" key; if the line is correct it is transferred from the temporary memory to the main memory by actuation of an "ENTR" key whereas if the line is incorrect it is cleared from the temporary memory by a "CLR" key. Single actuation of the "IND" key causes display of the number of stored lines associated with a given header. If the main memory is nearly full a row of decimal points is displayed at 1002, the keyboard being locked when the main memory overflows. For transfer of the stored data to a computer, store, or printer, the portable device is connected to an interface unit (Figs. 7A, 7B, not shown), the read-out data being processed to provide a desired format of the grouping and spacing of the characters.

Title: Improvements in or relating to an assembly for a hypodermic injector
IPC: A61M5/30
Filed: 1955-01-31
Abstract: 764.259. Hypodermic injection devices. SCHERER CORPORATION, R. P. Jan. 31, 1955 [April 26, 1954], No. 2815/55. Class 81(2) A needleless injector has a plunger, having limited axial movement, mounted in an adjustable bearing member so that medicament can be ejected from an ampoule as a number of small injections, the plunger being advanced appropriately between doses. A bearing disc 50, Fig. 2 supports the plunger 40 by means of its stem 41, but the axial movement of the plunger is limited by its shoulder 44 and the face of a disc 43, secured to its inner end. The disc 50 cannot rotate relatively to the main body 10 but can be adjusted axially by turning an internally threaded sleeve 12 until the end of the plunger bears against the stopper 33 of the ampoule 31. When the striking member 66 is thrust against the disc 43 by release of the driving springs 64, the plunger 40 and stopper 33 are advanced a distance equal to the space 47. The disc 50 is then advanced a similar distance by the sleeve 12 prior to the subsequent use of the injector. Compression of the driving springs 64 is perfomed by rotating a screw 62 by means of a head 14, Fig. 1, and, since the screw engages threads 61 in a central extension of the head 66, Fig. 2, the latter is drawn towards the left. When the screw has been drawn back a sufficient distance a step 71, Fig. 1, is engaged by a rotatable latch 83 which is later released, for the injection, by a stud 80 bearing against a trip lever 25.

Abstract: Vinyl chloride is polymerized or copolymerized with one or more ethylenically unsaturated monomers in aqueous dispersion with the use of oil soluble activators in the presence of mixtures of water soluble colloids and partial esters of aliphatic polyalcohols with a higher fatty acid or mixed esters of aliphatic polycarboxylic acids with 2 to 12 carbon atoms in which one acid group is esterified with an aliphatic polyalcohol and the remaining acid groups are esterified with aliphatic monohydric alcohols with 1 to 20 carbon atoms as suspension agents wherein acetyl-cyclohexyl-sulphonyl peroxide, or a mixture thereof with one or more other oil-soluble activators such as azo-di-isobutyronitrile, is used as the activator.  If a second activator is used it is present in an amount between 5 and 90% by weight of total activators.  Polymerization is carried out in an autoclave at constant temperature until the pressure falls.  In the examples, the other monomers are octyl acrylate and dioctyl maleate, while the dispersing agent is a mixture of polyvinyl alcohol and triglycerin monostearate.
