Filed: 1967-05-08
Abstract: 1,176,074. X-ray detectable surgical dressings. JOHNSON & JOHNSON. 7 May, 1968 [8 May, 1967], No. 21278/67. Heading A5R. A surgical dressing comprises a plurality of layers of an absorbent non-woven textile fabric contained in a textile fabric envelope, the dressing being rendered X-ray detectable. The dressing may be rendered X-ray detectable by impregnation with an X-ray opaque substance or by incorporating a detectable member, suitably attached to the inner wall of the envelope or to at least one layer of the non-woven fabric. The envelope may be woven or non- woven. The dressing may be sterilized by ethylene oxide or gamma rays. Suitable non-woven fabrics include those obtained by rearranging a bed of fibres into a mechanically interlocked fabric by passage of fluid through the bed. In the Example the X-ray detectable member comprises BaSO 4  embedded in polyvinyl chloride.

Materials for making gas, coke, and other products.-Residues obtained from the treatment of hydrocarbons such as mineral oils, tar oils, olefines, &c. with metal halides or with a metal such as iron or aluminium and halogen hydride, or the residues obtained directly by refining hydrocarbon oils such as mineral oils, tar oils, benzines, &c. with sulphuric acid, are subjected to dry distillation above 360‹ C. with an addition of substances having a neutralizing or refining action, such as calcium carbonate or other basic salts, fuller's earth, lead salts or oxides, iron oxide, powdered quicklime or calcined magnesia. .Extraneous gases or vapours such as steam, nitrogen, hydrogen, carbon dioxide may be introduced and reduced or elevated pressures employed. The first runnings from the distillation of residues from refining hydrocarbons with sulphuric acid may be. worked up into lubricating oils by polymerization and condensation, e.g. with the aid of metal halides and gaseous olefines, if desired in admixture with other hydrocarbons by the process according to Specification 299,086, [Class 2 (iii), Dyes &c.]. Mixtures of different kinds of residues including at least one containing metal halides or one acid resin may be utilized. In an example' 60 parts of a tar oil residue containing aluminium chloride. are mixed hot with 20 parts of a tar oil acid resin and 20 parts of a tar oil distillation residue together with 20 per cent of finely powdered limestone, the mixture when distilled at 520‹ C. yielding 55 parts of an oil comprising 60 per cent lubricating oil, 20 per cent fuel oil and 20 per cent low boiling point constituents.

Abstract: 784,356. Electric telemetering systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Aug. 2, 1955 [Aug. 9, 1954; Sept. 27, 1954], No. 22141/55. Class 40 (1). Apparatus for telemetering signals comprises means for phase modulating an audio frequency voltage in accordance with the signal, transmitting the modulated signal and the unmodulated audio voltage as amplitude or frequency modulated carrier frequency voltages, demodulating the carriers at the receiver and operating an indicator in accordance with the phase difference of the reconstituted audio frequency voltages. A plurality of measuring signals may be transmitted on different carriers with one unmodulated reference signal along a common transmission line or radio link. The phase modulation of a measuring signal may be obtained by the rotation of a control member 21 (Fig. 2) connected to the energized rotor 20 of a 2-phase selsyn-type transmitter, the stator windings 23, 24 being interconnected by a resistor R and capacitor C giving a voltage at terminals 27, 28 substantially constant in amplitude and with a phase angle equal to the angular rotation of rotor 20. At the receiver where the L.F. voltages are reconstituted, the reference voltage is fed to one winding 48 (Fig. 4) of a 2-phase motor 44 and the signal voltage to the rotor of a 2-phase selsyn 45 whose stator voltage is applied to the other winding 46 of the motor 44, which rotates to drive the rotor of the selsyn 45 until the phase difference between the voltages in windings 46, 48 is eliminated, an indicator 52 also being driven by the motor. 3-phase selsyns may alternatively be used (Figs. 3 and 5, not shown). In a telemetering system (Fig. 6) the individual phase modulation at 61<SP>1</SP>, 611<SP>1</SP> of an L.F. voltage from an oscillator 60 is used to modulate different carrier frequencies at 63<SP>1</SP>, 63<SP>11</SP> and amplified at 651, 65<SP>11</SP> for transmission, together with a reference signal comprising the output of oscillator 60 directly modulating another carrier frequency at 63. At the receiver the signals are amplified, separated by filters 69, 69<SP>1</SP>, 69<SP>11</SP> and demodulated at 70, 70<SP>1</SP>, 7011, the reconstituted, L.F., phase-modulated voltages being used to operate receiver motors 72<SP>1</SP>,72<SP>11</SP> coupled to indicators 731, 73<SP>11</SP>.

Abstract: 708,420. Mixing appliances. MASCHINENFABRIK STEINAU WOYTH & CO. Sept. 3, 1952 [Sept. 8, 1951], No. 22193/52. Class 86 [Also in Group XIII] An ice-cream freezer comprises a can 4 and agitating paddle 23 relatively rotatable, the paddle being given two additional oscillatory motions about axes at right angle to each other by an arm 15 bent in such a manner that the relatively movable parts of the drive are located outside the upper opening of the can, so that oil &c. cannot drop into the ice-cream. As shown, the can 4 is rotated within a fixed refrigerating receptacle 4a by gearing 3 which also drives two cams 9, 10. The cam 9 through a lever 5 rocks a tube 14 in which takes the downwardly bent end of the arm 15 so that the arm and the paddle 23 fixed thereto. are rocked through about 30 degrees on horizontal bearings 7, 8. The cam 10 through a lever 6 pivoted on the bearing 7 simultaneously swings the arm 15 about its bearing in the tube 14 so that the paddle has combined tilting and swinging oscillating motions within the rotating can. The arm 15 is bent in the form of an S and has a downwardly projecting pin 16 engaging a groove in the paddle relative rotation being prevented by a pin 26. The vertical edge and the bottom.of the paddle are provided with edges of plastic the vertical edge being slightly curved so as to contact the cam at one point with a rolling motion. A handle 24 is provided for removal of the paddle from the pin 16. To prevent bending. or fracture of the parts by lumps of ice the connection between the lever 6 and the arm 15 is yieldable against a spring in a tube 18. The can may be stationary and the paddle rotated in addition to its other movements.

Title: A jointing substance and processes for its preparation
IPC: C09J191/02
Filed: 1945-08-30
Abstract: <PICT:0620125/III/1> A jointing substance is prepared by adding an element of the sulphur group to a fatty oil, heating the mixture at a temperature greater than 220 DEG  C. to produce a vulcanized base, dissolving or dispersing the base in an organic solvent therefor and diluting the resultant solution or dispersion in an additional organic solvent which is more volatile than the first organic solvent, so as to produce a flowable jointing substance, subsequent evaporation of the volatile solvents leaving a jointing medium of a tacky nature.  Selenium and tellurium may be substituted for sulphur, and the fatty oils specified comprise castor, linseed, cottonseed, rape, cod-liver oil and lard oils. The sulphurized products are insoluble in the common organic solvents, but are rendered soluble in ordinary solvents by conversion into a jelly form by the treatment with the first organic solvent which may be toluene, xylene, or solvent naphtha, preferably by boiling under reflux and cooling the solution obtained.  The jelly is then soluble in or may be thinned by the usual solvents such as carbon tetrachloride, ethyl acetate and acetone.  When such jointing solutions are applied to the joint face, both thinners and toluene &c. evaporate and leave the jointing compound.  To prevent gelation of the stronger solution, the toluene &c. is added to the molten oil-sulphur product as soon as prepared, i.e. at 226 DEG  C. for the castor oil-sulphur product. Suitable apparatus for effecting this addition comprises a lagged flask 7, a condenser 9, and a funnel 10 communicating with the flask and condenser by pipes 11 and 13 respectively.  The above product is prepared in the flask and is held for a short time at 226 DEG  C. Toluene in the funnel is then run on to the hot mass, vaporizes, condenses in the condenser, the condensate is forced into the funnel by the increase in pressure developed in the flask and so returns to the latter, repeating the cycle until all the toluene is in the flask.  The mixture is then boiled, cooled and the thinner finally added thereto.
