Title: Improvements in processes for applying paint by electrophoretic deposition on to ferrous surfaces
IPC: B05D1/04
Filed: 1971-01-06
Abstract: 1293883 Treating ferrous surfaces; electrodepositing paint AMCHEM PRODUCTS Inc 6 Jan 1971 [6 Jan 1970] 549/71 Headings C7B and C7U A ferrous metal surface is treated with a solution containing between 0À5 and 10 p.p. m. of copper in any soluble form, and is subsequently electro-coated with a light-coloured paint; the pre-treatment with the Cu eliminates irregularities in colour of the paint. The ferrous metal may be treated only with an aqueous solution of a Cu salt, such as the nitrate, acetate, or chloride, but is preferably phosphatized in which case the copper solution treatment is before, during, or after phosphating. Preferably the surface is contacted with a Cu-containing phosphate solution which is either (a) a "coating phosphate" solution of pH 1À8 to 3À5, free acidity 0À3 to 10, and total acidity 5 to 100, which contains an oxidant for ferrous ion or (b) a "non-coating" phosphate solution based on NaH 2 PO 4 , e.g. 2-20 g/l, and containing an accelerator, e.g. 0À05-0À5 g/l Na molybdate, either (a) or (b) being applied by spraying for 1-2 mins. at 60-70‹C., or immersion for 2-5 mins. at 65-76‹C., and desirably being followed by a rinse in a trivalent and/or hexavalent Cr solution. The electro-phoretic paint is a conventional paint containing methacrylic, acrylic, alkyd, melamine, or epoxy resin or a mixture thereof as anionic resins, and may have a solids content of 8-17 wt per cent, pH 7À5-9À5 and be deposited at 15-36‹C. for 30 sec - 5 min. at 50-450V and 1À08-108A/m<SP>2</SP>. Deposition is followed by mixing, e.g. with water and curing, e.g. at 148-205‹C, for 20-30 mins. The process eliminates blotches and stains from light-coloured, particularly white, paint, and where the Cu content of the solution is high, tends to impart a faint bluish tinge to the paint. Specific phosphating solutions (which may also contain Cu) contain (1) NaH 2 PO 4 , Na molybdate, wetting agent, aralic acid and NaF and (2) Zinc, H 2 PO 4 <SP>-</SP>, NaClO 4 , NaNO 2 , and Ni.

Title: Flash lamp igniter for photographic cameras
IPC: G03B15/04
Filed: 1947-01-07
Abstract: 639,544. Flashlight photography. WOOD CORPORATION, J. B. Jan. 7, 1947, No. 552. Convention date, Aug. 31, 1946. [Class 98 (i)] [Also in Groups XXIV and XXXV] In a flash-lamp igniter for photographic cameras, an electric generator mounted in a housing has a wire-wound stator and a permanent magnet rotor, the rotor being mounted on a drive shaft by means of an over-riding clutch which enables the shaft to drive the rotor, but permits the rotor to continue its rotation when the shaft is abruptly stopped. A spring which may be connected between the shaft and the housing may be tensioned by rotation of the shaft in one direction in order to turn the shaft rapidly in the opposite direction, an abutment being carried by the shaft to engage a stop on the housing when the shaft has been rotated approximately one revolution by the spring. The shaft may carry a cam which actuates the shutter of a photographic camera at the moment when a flash occurs, and the housing may be releasably attached to the camera. As shown, Fig. 3, a stator 16 having an even number of windings is mounted inside a central part 8b of a housing. A rotor 17, consisting of a magnetized disc with alternate poles equal in number to the number of stator windings, is carried within the stator by a sleeve 24 freely mounted on a driving shaft 25 journalled at 26, 27. The lower end of sleeve 24 is of enlarged to contain a disc 29, Fig. 5, cut away in part to house a ball 30 urged into contact with sleeve 24 and disc 30 by a spring 31, forming a clutch which operates when shaft 25 is driven anticlockwise in Fig. 5 to drive the rotor 17. If the shaft is suddenly stopped the clutch permits the rotor to continue its rotation until stopped by friction. The upper end of shaft 25 is connected to one end of a spiral spring 34, Fig. 3, the other end of which is fixed to the housing. When the spring is wound by a knob 43 on the lower end of the shaft, a projection on the shaft bears against the nose of atrigger 40 to prevent unwinding. The end 42 of the trigger is pressed to release the shaft, which turns through almost 360 degrees before it is arrested by its projection meeting a preferably cushioned stop on the housing. Rotation of the rotor induces a current in the stator windings connected to a flash-lamp 10 which is thereby ignited.' A cam 46 mounted below the rotor on shaft 25 operates a plunger 47 of a flexible shutter release 48, and is adjustable so that the shutter of an associated photographic camera may be fully open when the flash reaches peak intensity. Other flash lamps, remote from the camera if required, may be connected by a plug and socket in parallel with the lamp 10. The housing may have an attachment whereby it is readily fixed to the camera, or removed and operated at a distance therefrom, the cable 48 having extra length for this purpose.

Title: Improvements in combinations of a hpmv lamp with means for cooling it
IPC: H01J61/52
Filed: 1940-01-12
Abstract: 538,793. Metal-vapour lamps. GENERAL ELECTRIC CO., Ltd., DUNHAM, C. R., and FRANCIS, V. J. Jan. 12, 1940, No. 736. [Class 39 (i)] In artificially cooled high pressure metal vapour lamps of the type in which the cooling device is controlled by the current through the lamp or the voltage across it or both, the lamp is combined with two relays A, C and a switch or relay B. The relay A operates to set the cooling device in operation when the voltage across it has some value less than the normal running voltage but considerably greater than the voltage across the lamp just after it has been switched on from cold. The relay C operates only if current is passing through the lamp and puts the relay A in circuit. B is a relay or hand operated switch for setting the cooling device in operation after the lamp has been extinguished owing to some drop in the supply voltage in order to cool the lamp quickly to the point at which it can be started again as soon as possible. If it is a relay it functions only if the voltage across the lamp has a value greater than the normal running voltage but less than the normal supply voltage. The cooling device may be a current of air or other gas or liquid circulated by a blower &c.

Patent GB-799107-A (GB)
Title: Improvements relating to the production of threads by the viscose spinning process
IPC: D01F2/06
Filed: 1955-01-11
Abstract: Viscose is spun into a hot aqueous acid saline bath, and the threads so produced are stretched to the maximum extent possible without rupture in a second hot aqueous acid bath containing a lower concentration of acid than the first bath, the threads being allowed to shrink freely after passing through the second bath while still in the acid state, whereafter the threads are washed (while completely free from tension) in such a manner that they can absorb moisture to a maximum extent, and are then treated in an oil-in-water emulsion bath from which they are supplied to a collecting device; they are then passed, while subjected to predetermined tension, over a system of drying rollers heated to over 100 DEG  C. on which they are initially dried to a moisture content of not below 60 per cent (based on the dry thread), before being finally dried by passing them through a drying shaft in counter-current to a stream of hot air, at a tension less than that at which they left the drying rollers.  In the example, a viscose is spun into an aqueous bath having a temperature of 50 DEG  C. and containing 126 grams per litre of sulphuric acid and sodium, magnesium and zinc sulphates.  The threads are thereafter stretched by 100 per cent in a second aqueous bath containing 4 per cent of sulphuric acid at a temperature of 95 DEG C.  The threads are allowed to fall freely from the second bath delivery roller into a centrifugal spinning pot, in which they are covered by a cloth and sprayed with after-treatment liquids.  The threads are then fed from the pot in the form of a tow through a mangling device, passed through an oil-inwater emulsion finishing bath and then passed through a second mangling device to reduce their moisture content to about 145 per cent based on the dry weight of the thread.  The threads are then led at predetermined tension over drying rollers maintained at 140 DEG  C. and their moisture content is thereby reduced to 60 per cent (based on dry thread). Finally the threads are led from the rollers through a drying shaft in countercurrent to a stream of air at 100-120 DEG  C.

Title: Internal combustion piston engine with charging coefficient increased by means of fresh-gas resonance swings
Inventor: CSER GYULA
IPC: F02B75/18
Filed: 1987-02-12
Abstract: A reciprocating piston-type internal combustion engine includes an intake gas conduit assembly in which intake gas resonance oscillations are generated for increasing the charging efficiency of the cylinders. The intake gas conduit assembly has a feed resonance system including a feed resonator vessel connected with the intake ports of a group of cylinders whose suction strokes do not significantly overlap and a feed resonance pipe communicating with the feed resonator vessel. The intake gas conduit assembly further has an auxiliary resonance system including a closed auxiliary resonator vessel and an auxiliary resonance pipe opening into the auxiliary resonator vessel, an intermediate resonator vessel coupled with the auxiliary resonance pipe and the feed resonance pipe and an intake gas inlet pipe coupled with the intermediate resonator vessel. The feed resonance system and the auxiliary resonance system are tuned to one another by a dimensional selection such that at a predetermined first resonance rpm of the engine the intake gas oscillations generated in the feed resonance pipe and the auxiliary resonance pipe by intermittent suction strokes of the cylinders forming the group are in phase effecting an increase in the charging efficiency and the intermediate resonator vessel is dimensioned such that at a predetermined second resonance rpm of the engine in an operational rpm range the oscillations in the feed resonance pipe and the auxiliary resonance pipe are of opposite phase, effecting an increase in the charging efficiency.
