Title: Improvements in shock absorbers
IPC: F16F7/06
Filed: 1926-09-28
Abstract: 282,881. Ludwig, H. Sept. 28, 1926. Vibration-dampers.- In apparatus for checking the rebound due tc vehicle springs, a flexible band is braked bv means of a block over which it passes, the block also resting on another part of the band. In the apparatus shown in Figs. 1 and 2 secured to the frame of a vehicle, one end of the band 7 is secured to the axle and the other end is led over a block 8 and round a drum 6, to which it is finally secured. The drum 6 is rotated on a sleeve 2 projecting from the bed plate 1, by means of a spring 3, so as to tighten the band. One end 5 of the spring engages the drum and the other passes over a pin 4 projecting from the base 1. The block 8 is pivoted on the pin 6 and bears upon an inner coil of the bard with a pressure depending upon the band tension A member 10 mounted in a slot in the block 8 is vertically adjustable so that the band may be partly lifted off the block. In the modification shown in Fig. 3 the block 8 is constructed as a two-armed lever pivoted at an intermediate point 9 and the longer arm bears upon an eccentric 11 which may be operated by an indicating arm outside the casing. In this way the pressure exerted by the block upon the inner coil of the band may be varied. In a further modification, the apparatus as a whole may be turned about the pivot 15 and clamped in position so as to vary the length of the arc of contact between the block 8 and the band. A notched coupling may be employed for this purpose.

Class 38(5) Dielectric heating equipment comprising electrodes 14, 15 supplied with high frequency A.C. by an oscillator 12 and power supply 11, is provided with means for cutting off the oscillator when the D.C. resistance between the electrodes drops below given value prior to arcing. A D.C. potential is applied to the electrodes by a battery 27 connected in series with a battery 24 and resistors 25, 26 providing a potential on the control grid-21 of a thyratron 18 slightly below the firing point thereof. On dropping of the resistance between the electrodes, the resulting increased D.C. current causes the potential on grid 21 to rise and thyratron 18 fires, connecting an arc-suppressor power supply 17, which is connected to the grid of oscillator 12, in series with power supply 11. A high negative potential sufficient to cut-off oscillator 12 is produced on the grid thereof and is maintained until the end of a period determined by a time control 10.

Filed: 1946-08-16
Abstract: 615,034. Magnetrons. M-O VALVE CO., Ltd., and MACRAE, W. Aug. 16, 1946, No. 24493. [Class 39 (i)] In a magnetron having two sets of interlaced anode segments a1, b1, c1, a2, b2, c2, Fig. 2, adjacent segments being connected alternately to two plates 1, 2, one set of anode segments is displaced slightly from the symmetrical interlaced position relatively to the other set in the sense of a slight rotation-approximately one degree-about the common axis of the two sets. The anode segments are formed by pressing out a cylindrical boss in a metal blank, cutting slots in the boss, cutting off its end, and trimming the segments by etching and grinding ; the plate 1 or 2 formed from the blank also has four locating holes 33, 34, 35, 36, Fig. 3, so positioned that the centre line of the slot between segments a1, b1 lies, say, 25 minutes of a degree off the diameter passing through the centres of the holes 33, 35. The other plate is similarly constructed except that the displacement of 25 minutes of a degree is to the other side of the corresponding diameter; thus, when the plates 1, 2 are assembled in a jig and located in position by the holes 33, 34, 35, 36, the relative rotational displacement from the symmetrical interlaced position is 50 minutes. The plates 1, 2 each have two tags 3, 4, which pass through a mica base-plate 5 and are welded to a metal collar 6 secured to the base-plate 5 by tags 7, and are provided at their upper ends with tags 10, 11 passing through a mica plate 12. Mica side plates 13, 14 and metal side plates 19, 20 secured thereto are held in place by tags 15, 16 and double tags 17, 18 welded to the plates 1 and 2. The heater 23 of the cathode 21 is connected to wires 28, 29, via tags 24, 25 and metal strips 26, 27, and the cathode 21 is connected to the tag 25 by a metal strip 30. Mica washers attached to the wires 28, 29 may be provided for locating the electrode assembly within the envelope.

Title: Curing oxidized synthetic oils with so
IPC: B05D3/10
Filed: 1957-08-02
Abstract: The hardness of films made from oxidized synthetic polymeric drying oils which comprise polymers of conjugated diolefines having 4 to 6 carbon atoms or copolymers thereof with minor proportions of ethylenically unsaturated monomers copolymerizable therewith, is improved by contacting with sulphur dioxide. Specified dienes are butadiene, isoprene, dimethyl butadiene, piperylene and methyl pentadiene.  Specified ethylenic monomers are styrene p-methyl styrene, dimethyl styrene, diethyl styrene, acrylonitrile, methacrylonitrile, methyl acrylate, methyl methacrylate, vinyl isobutyl ethers, methyl vinyl ketone and isopropyl methyl ketone. The fibres may be reacted with curing promoters or cross-linking agents, e.g. polyamines, urea- and phenolformaldehyde resins and diisocyanates prior to treatment with the sulphur dioxide.  The Specification describes the preparation of polymers from (A) butadiene-1,3 in the presence of mineral spirits, t-butyl hydroperoxide and diisopropyl xanthogen disulphide to form an oily polymer which is then fractionated; (B) and Example (1), butadiene-1,3 and styrene in the presence of mineral spirits, dioxane, isopropanol and sodium to form a polymer which is (B) purified by neutralization and distillation and in (1) blown with air at 230 DEG  F.  The oxidation is effected by blowing solutions of the oils optionally in the presence of a catalyst e.g. the naphthenates and octoates of cobalt, lead, iron and manganese, with air or oxygen, specified solvents being aliphatic and aromatic hydrocarbons boiling up to 250 DEG  C., e.g. benzene, toluene, hemimellitine pseudocumene, mesitylene, propyl benzene, cymene, ethyl toluene, methyl ethyl benzene and xylene. In Examples II to IV, films of the oxidized polymer oils coated on to metal plates are contacted with sulphur dioxide, the oxidized polymer oil of Example III having been reacted with a trimethylol propane-tolylene diisocyanate reaction product prior to being formed into a film.  Specifications 677,774 and 821,979 are referred to.

Inventor: KRIEGE ERNST
IPC: C07D401/12
Filed: 1958-08-01
Abstract: 4- (Pyridine carboxylic acid amido- or alkylamido)-2 : 3-dimethyl-1-phenyl-5-pyrazolons are prepared by reacting the reaction product of a metal salt of a pyridine mono- or di-carboxylic acid and a thionyl halide (this reaction product being free from hydrogen halide) with a 4-amino-1-phenyl-2 : 3-dimethyl pyrazolone or a 4-monoalkylamino-1-phenyl- 2 : 3-dimethyl pyrazolone.  In the first stage of the reaction thionyl chloride is preferably reacted with an alkali metal or copper salt of nicotinic, isonicotinic or quinolinic acid to give the acid chloride in the case of the monocarboxylic acids and the anhydride in the case of the dicarboxylic acid.  The second stage of the reaction may be conducted in the absence of acid binding agents to yield final products in the form of their hydrohalides.  The latter may be subsequently converted to the free bases by treatment with alkalis.  When pyridine dicarboxylic acid salts are used as starting materials, the final products, formed by way of the anhydrides, contain a free carboxyl group on the pyridine ring.  The examples describe the preparation of 4-(pyridine-3-and 4-carboxylic acid amido)-2 : 3-dimethyl-1-phenyl-5-pyrazolones, 4-(pyridine-3-carboxylic acid methylamido)-2 : 3-dimethyl-1-phenyl-5-pyrazolone and 4-(pyridine-2-carboxylic acid-3-carboxylic acid amido)-2 : 3-dimethyl-1-phenyl-5-pyrazolone.
