Abstract: 1,253,478. Crease resistance. J. A. PINATEL. 8 June, 1970, No. 27660/70. Heading DIP.  A process for treating fabrics, e.g. cotton and synthetic fibres with an elastomeric organo siloxane composition capable of vulcanizing at room temperature in the presence of moisture. Suitable organo siloxanes are where Ac is a saturated aliphatic monoacyl radical of a carboxylic acid; R is selected from the group consisting of monovalent hydrocarbon radicals, halogenated monovalent hydrocarbon radicals and cyano alkyl radicals and n is >5 and generally 20-5000 for a convenient viscosity. The siloxane may be applied from a solution or emulsion by dipping, spraying or padding and the fabric contains 1-5 ounces of polysiloxane per sq. yd. For application to the fabric the siloxane can be diluted as required with an inert organic solvent and a 20% by wt. solution is satisfactory. After impregnation the fabric is passed through a drying oven at 140-150‹F., leaving 10-15% by wt. of solvent on the fabric. The fabric is then ready for finishing and can either be immediately made into end products or stored for future use in an air and moisture tight enclosure. The cut and sewn product is then finished in the vulcanizing step in which the fabric is either subjected to wet steam atmosphere for 15-20 minutes or placed in a hot steam and vacuum press. In such a press the product may be subjected to 20 secs. of steam, followed by 10 sees. of 5000 lbs./sq. in. pressure and 5 secs. of vacuum, these steps overlapping one another if desired. The product is then aged by hanging in a moist atmosphere for 2-3 hours to allow the curing process to be completed by expelling all of the solvent. A preferred siloxane is the reaction product of dimethylpolysiloxane and an acyl oxysilane of general formula R Si(OAc) 3 .

Title: Stamp dispenser
IPC: G07F11/68
Filed: 1965-06-30
Abstract: 1,038,760. Stamp dispensers. ROTOSTAMP CORPORATION. June 30, 1965 [July 6, 1964], No. 27798/65. Heading G4T. In a stamp dispenser in which a plurality of stamps are dispensed from a roll after guidance around a toothed drum on manual actuation of a continuous chain 66 (Fig. 8, not shown), the chain 66 drives a sprocket wheel 53 coaxial with the drum which drives by way of a tensioned spring 59 a toothed wheel 57 rigid with the dispensing drum to deliver the stamps, a detent 80 mounted on a yieldable member 69 engaging between the teeth of the wheel 53 prevents illicit removal of stamps except when released by engagement of a projection 76 with an extension 77 on the actuated chain 66. The machine is locked against use by a bar 82 which prevents the detent 80 disengaging from the toothed wheel 57. During use the bar is rotated by an external key such that the member 69 cooperates with a groove 84 therein. A further locking device comprising a closely fitting bolt held by a nut on the inside of the machine locks vertical plates between the dispensing mechanism and the roll of stamps, to the outer housing, thus preventing tampering with the mechanism. At the bottom of the finger aperture through which the chain elements 67 (Fig. 3, not shown) project, the finger co-operates with an abutment 183 which actuates a spring- biased lever 188 to coact with a further chain element preventing overrun of the dispenser. The chain 66 co-operates with a further sprocket 155 to actuate a counter. The dispensing drum is of a width to dispense one or five stamps and has one or two circumferential grooves with pins on either side to co-operate with the stamp perforations and retaining members disposed over the drums have tongues co-operating with the grooves to hold the stamps firmly on the drums. Several dispensers for different denominations may be placed side by side in the same housing. The stamps pass a serrated blade at the dispensing opening of the machine. A spring partition 126 protects the roll of stamps 5 from dust falling from above. The top and back central part of the machine may be removed after actuation of a lock 24 to load a fresh roll of stamps which rests on rollers in a carrier in the machine.

Title: Electrostatic generator
IPC: H02N1/08
Filed: 1951-11-29
Abstract: 702,421. Electrostatic generators. SOC. ANON. DE MACHINES ELECTROSTATIQUES S.A.M.E.S. Nov. 29, 1951 [Nov. 29, 1950; Feb. 20, 1951], No. 28019/51. Class 35 An electrostatic generator for producing ignition impulses comprises two groups of oppositely charged stationary plates arranged alternately and surrounding a rotor with charge-carrying plates connected to a distributer arm through which they are alternately discharged in opposite directions under the influence of the stator plates, to produce the ignition impulse. As shown diagrammatically in Fig. 1, for a generator providing four ignition impulses per revolution, the stationary charge inducing plates 1 are maintained at a negative potential by an external supply 3 while plates 2 are similarly charged positive from a source 4. The rotary charge-carrying plates c are connected to a distributer arm 7 which passes close to spark-over electrodes 8 to discharge alternate positive and negative charges from the plates c as these pass the alternately charged stationary plates 1, 2. Fig. 3 shows in a practical form a single-cylinder double-ignition generator enclosed in a pressure-filled casing 20, the driving shaft 36 being sealed by an oil-filled gland 28. A pair of stationary charge inducing plates 66 each subtending nearly 180 degrees are supported by insulating end-covers 46, 48, and the rotor carries a main generator part 72 and an exciting part 74. The main generating plates 76 are connected to electrodes 78 so that as they pass the stationary plates 76 they simultaneously deliver ignition impulses through electrodes 82 and terminals 92 to the engine. The exciting plates 100 are connected respectively to sliprings 102, 103 having conducting sectors which contact two pairs of brushes 108, 109 connected respectively to one of the inducing plates 66 and earth so that the plates 100 are alternately connected to earth and to the inducing plate to maintain these in an excited state. A modification is described which may be applied to machines as in Fig. 1 in which the number of chargecarriers is less than the number of inducing plates. The exciting plates are placed on the rotor between the main output plates and are divided into three mutually insulated smaller plates arranged in succession round the rotor periphery and each connected to a contact segment for alternate connection to earth and the inductor plate to be charged. The segments are arranged to pass within over-voltage spark-gap distance of a voltage limiting discharge electrode before contacting the brush connected to the inductor plate, so that if the voltage is excessive, the air-gap breaks down and so reduces the potential. Specification 671,033 is referred to.

Filed: 1960-08-16
Abstract: <PICT:0897584/IV (b)/1> In the recovery of isobutylene from C4 hydrocarbons by selective extraction with aqueous sulphuric acid to form tertiary butyl alcohol followed by regeneration of isobutylene from the acid solution, the acid used contains less than 2% by weight of non-aqueous impurities and the acid solution, prior to regeneration, is passed to a venting zone maintained at 57 DEG C.-66 DEG C.  Using a two stage process, C4 feed is fed via heater or cooler 11 where the temperature is adjusted to 23 DEG C.-35 DEG C., the pressure being 6.9-9.98 atmospheres, and mixed with circulating emulsion from the first stage and sulphuric acid from the second stage already containing some tertiary butyl alcohol.  The mixture is pumped via cooler 15 into reactor 14. Most of the emulsion is recycled, the remainder being bled off to settler 16 whence remaining hydrocarbons are removed from the final acid solution.  The hydrocarbons pass to the second stage where they are mixed with circulating emulsion and fresh sulphuric acid of 55%-65% by weight strength.  The second stage is maintained at 12 DEG C.-35 DEG C. and at a pressure 0.068-2.04 atmospheres higher than the first stage. The mixture is pumped to cooler 30 and reactor 22 whence most of the emulsion is recycled, some being bled off to settler 13 where acid is removed and passed to the first stage and remaining hydrocarbons are removed from the process.  Acid solution from settler 16 is heated, preferably by mixing with 10.5 kg./cm.2 steam and passed to venting zone 23 where a defoamant, e.g. a spray of tertiary butyl alcohol, may be added if desired.  Here undesired impurities are removed; these may be led to a n-butylene scrubber and then recycled to the first stage of the extraction.  Isobutylene is recovered conventionally in tower 25 by heating and diluting, e.g. with steam. The spent acid is reconcentrated, preferably by distillation at 5.08-25.4 cm. mercury pressure and an outlet temperature of 65 DEG C.-93 DEG C.
