Title: Improvements in and in the manufacture of piston and like packing rings
IPC: B22F5/02
Filed: 1943-04-01
Abstract: 566,385. Making piston &c. rings. BRITISH PISTON RING CO., Ltd., TWIGGER, T. R., and JUDD, J. A. April 1, 1943, No. 5211. [Class 83 (ii)] [Also in Group II] Piston and like packing rings are made from porous material, the density of which is controlled according to the conditions required in service. The density ranges from 6.1 to 7.3. The rings may be made from a base of powdered ferrous metal by cold pressing and sintering, or by hot pressing with or without subsequent sintering. The material may be as described in Specifications 538,227, [Group II], and 560,483. Graphite may be added and any or all of the following alloying elements may be incorporated : nickel, copper, chromium, molybdenum, tungsten, vanadium, titanium, manganese and phosphorous. The special contour may be imparted to the rings during or prior to sintering as described in Specification 551,232 and in a reducing or neutral atmosphere as described in Specification 558,408, or the shape may be imparted during the pressing operation as described in Specification 538,679, or by a repressing operation at a non-oxidising temperature as described in Specification 552,532. Sintering at 1050‹ C. for 1¢ hours, 1075‹ C. for 1 hour and at 1100‹ C. for ¢ hour all yield the.same density, the other conditions being constant. In a given pressure an increase of 20‹ C. in the sintering temperature or of from 30 to 60 minutes in the time raises the density 0.2. Raising the pressure from 40 to 50 tons per square inch increases the density from 6.5 to 6.7 and a further increase of 10 tons yields a density of 6.9. Particles of dendritic shape result in a higher density than spheroidal particles.

Title: Improvements in plasticizers
Inventor: OSCHATZ FRITZ
IPC: C08K5/10
Filed: 1950-03-02
Abstract: Compounds R1OCOO(CH2)4OCOOR2, wherein R1 and R2 are saturated chlorine-containing aliphatic radicles with 6 to 18 carbon atoms in all, are plasticizers for synthetic resins.  Resins mentioned are vinyl polymerizates, e.g. polyvinyl chloride, polyvinylidene chloride, polystyrene, polyvinyl esters of organic acids, polyacrylic compounds or interpolymerizates of such vinyl compounds, aldehyde and ketone resins, cellulose esters, e.g. nitrocellulose and cellulose esters of organic acids, and phenol- or maleic acid-modified colophony esters.  Conventional plasticizers, fillers, stabilizers and dyestuffs may be present.  The incorporation of the ester with the resin may be effected in the usual way, e.g. by kneading or rolling or the ester may be added to an aqueous emulsion of the resin.  Generally 10-60 per cent of ester is present.  The compositions may be used in lacquers and worked in the usual way to yield lamin , films, foils or bands, for sticking surfaces together, for coating wood, metal, fabrics or paper and for the preparation of cable compositions, oilcloths, artificial leather and floor coverings.  In examples: (1) P.V.C. is plasticized with the bis-omega-chlorbutyl carbonate of butanediol-1,4 and in the remainder lacquers are made comprising together with conventional volatile solvents and the bis-omega-dichlorbutylcarbonate of butanediol-1.4 (2) pyroxylin; (3) a synthetic resin derived from cyclohexanone and methylcyclohexanone by caustic soda treatment, carbon black and pyroxylin; (4) crude castor oil and pyroxylin; (5) a U.-F. condensation product and pyroxylin; and (6) polystyrenes.ALSO:Compounds R1OCOO-(CH2)4OCOOR2 wherein R1 and R2 are saturated chlorine containing aliphatic radicles with 6 to 18 carbon atoms in all are obtainable by reaction of the bischlorcarbonic acid ester of butanediol-1,4 with monohydric saturated chlor-alcohols such as omega-chlorbutanol and its homologues or ethylene glycol mono-omega-chlorethyl ether, or by reacting chlor-carbonic acid esters of these chlor-alcohols with butanediol-1,4.  They are plasticizers (c.f. Group IV (a).  In an example (1) the bis-omega-chlor-butyl-carbonate of butanediol-1,4 is made by reacting butanediol-1,4 with chlor-butyl-chlor-carbonate.ALSO:Natural resins e.g. colophony and dammar, are plasticized with a compound R1OOCO(CH2)4 OCOOR2, where R1 and R2 are saturated chlorine-containing aliphatic radicles with 6 to 18 carbon atoms in all.

Convention date, Feb. 21, 1929. [Class 35.] To minimize noise and vibration in a vacuum cleaner having a motor and fan unit within an outer casing, a spring mounting is arranged between the unit and casing so as to allow yielding movement of the unit in all directions about its centre of gravity. These mountings are applicable to cleaners with horizontal or vertical axes and may be arranged to insulate the unit electrically from the casing. In the form shown in Fig. 1, the motor 27 and fan 28 are supported by pairs of conical springs 31 bearing on a ring 29 on the motor casing and two angle rings 32, 33 secured to the cleaner casing. Bolts 34 on the axes of the springs may be used to limit the movement of the unit during transport or in case of extreme mechanical shock. The ring may be of metal or oscillation-damping material, such as rubber, and it may, alternatively, be replaced by a number of lugs on the motor casing. Fig. 3 shows a form in which the unit is carried in a resilient ring 41 within the cleaner casing by the flexible bolts 38 which secure the endplates 36 of the motor casing. In an alternative arrangement, Fig. 5, the unit is suspended in a plane passing substantially through its centre of gravity by compression springs 44 bearing at one end in cups 45 on the motor casing and at the other in depressions 46 in the cleaner housing optionally provided with insulating inserts 48. Reference is made to the resilient mounting of a fan unit by means of one or more resilient members which are always under tensile stress, as described in Specification 341,241. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following:-(i) A Cardan suspension for the motor fan unit 1, Fig. 3 (Cancelled), comprising a ring 17 and pivots 16, 18. The suspension either wholly or in part may be of resilient material, the pivots, for example, being of rubber.

Abstract: 1,170,734. Gas analysis, electrical. W.A. WISEMAN. Jan. 27, 1967 [Feb. 10, 1966], No.5808/66. Heading G1N. In a method of determining the amount of a given component of a gas stream, a gas (e.g. oxygen) which is reactive with the component is produced in a first electrolytic generator Fig.2 and an amount thereof at least sufficient to react with the whole of said component is fed into the stream. The stream is then passed into a reactive gas detector which produces an electrical signal dependent upon the proportion of reactive gas in the stream which signal is amplified and fed back to control the first generator so as to maintain a constant proportion of reactive gas in the stream. The gas stream is then passed through a reactor (which may be a combustion chamber heated to 800 -1, 000 C) to effect reaction between the said reactive gas and said component. A further quantity of reactive gas is produced in a second electrolytic generator and is fed into the gas stream from the reactor. The stream is then passed through a second detector for reactive gas which detector produces a second electrical signal dependent upon the proportion of reactive gas, which signal is fed back to control the second generator and maintain constant the proportion of reactive gas entering the second detector. The coulombs taken by the second generator provides an indication of the presence of or a measure of the amount of said component. Known types of oxygen detectors may be used, e. g. a Herch cell or a paramagnetic oxygen detector. Alternatively the reactive gas may be hydrogen, or chlorine. Specification 1, 112, 771 is related.
