Title: Improvements in upholstery pads
Inventor: HAND JOHN
IPC: D02G1/02
Filed: 1950-08-24
Abstract: Upholstery pads or sheets of animal hair, e.g. horse or pig's hair, are obtained by twisting or plaiting the fibres into a rope whereby a curl is imparted to them, treating the fibres with a liquid setting agent (which may be applied before or after the fibres have been twisted or plaited) or with a gaseous setting agent applied after twisting or plaiting, which chemically reacts with the fibres and sets the curl, fixing the curl with the removal or neutralization of any residual setting-agent remaining on the fibres, untwisting the fibres, working them into a loosely-intermingled expanded mass, applying an adhesive substance, in the liquid or liquid dispersion form, forming the mass into a pad or sheet of the desired shape and finally drying, the adhesive being applied before or after the fibres have been worked up into an expanded mass or before or after the mass has been formed into a shaped pad.  Specified setting agents are thioglycolic acid, alkali metal and ammonium thioglycolates, sulphides, e.g. ammonium sulphide, and alkali metal hydroxides, carbonates, sulphites and borates which are employed in aqueous solution, that of ammonium thioglycolate preferably having a pH of 9-10.  A gaseous setting agent, e.g. hydrogen sulphide, may be employed.  The fixing operation may be effected by washing, or if the setting agent is volatile, by evaporation.  Alternatively, chemical reaction or heat may arrest the action of the setting agent.  For example, if the setting agent is alkaline or a reducing agent, then the fixing agent may be acidic or an oxidizing agent respectively, suitable oxidizing agents being hydrogen peroxide, sodium hypochlorite and sodium bromate.  Air is preferably removed by suction from between the twisted fibres prior to or simultaneously with application of the setting agent, and also, if desired, the fixing agent, as described in Specification 738,566.  Suitable adhesive substances are natural or synthetic rubber, polyvinyl chloride and butadiene-styrene copolymers, which may be applied by spraying or dipping, a subsequent heat operation being necessary to vulcanize the rubber when an uncured latex is employed.  The fibrous mass is shaped into pads in a mould or formed into a sheet on a travelling belt. Specification 464,659, [Group VIII], is referred to. According to the second Provisional Specification the process is also applicable to vegetable fibres.  Specifications 341,936, [Group XIV], and 355,004, [Group VIII], are referred to in both Provisional Specifications.

Abstract: 866,947. Thermally-actuated valves. SERCK RADIATORS Ltd. July 6, 1959 [July 7, 1958], No. 21650/58. Class 135. A thermally-actuated valve for automatically maintaining by means of a heat-exchanger a substantially constant temperature in the cooling water jacket of an I.C. engine comprises a valve body 2, Fig. 1, including a removable hollow insert 16 formed with four coaxial annular seatings 6, 7, 8, 9 engageable with valve closure elements 12, 13, 14 interconnected by an axial stem 15. Connections 3, 4, 5 connect the valve body to the jacket water, a by-pass in the circulating system and a heatexchanger respectively. The stem 15 abuts a thrust piece 23 of a thermostatic unit comprising a cylindrical cage formed by a pair of end-plates 20 interconnected by tie-rods 21 and capsules 22, 24 filled with wax or other expansible substance and urged apart by a spring 27. An adjustable stop 26 carried by the cover-plate 18 abuts the capsule 24 and a spring 19 opposing the expansion of the capsules abuts the closure element 14 and a closure cap 18a. When the jacket water is cold the valve elements 12, 13 are seated on the seatings 6, 7 so that water flows from the connection 3, through passages 10, 11 around the insert 16, the seatings 8, 9 to the by-pass outlet connection 4. When the jacket water begins to hot up the capsules 22, 24 expand leftwardly to unseat the valve elements 12, 13 from their seatings 6, 7 to divert some of the jacket water to the heatexchanger through the connection 5, and in the event of the jacket water reaching an upper limit of temperature, the valve elements 13, 14 close on the seatings 8, 9 so that all the jacket water passes through the heat-exchanger. In a modification, Fig. 2, the connection 4 is formed in the end of the valve body and the insert 16 is extended to receive a cap 18b against which the spring 19 abuts. The adjustable stop 26 is replaced by a member 28 axially movable by a screw 29 and carried by a sleeve 30 so that in the event of failure of the capsules the valve elements can be moved manually to pass all the jacket water through the heat-exchanger. In other modiifications, the water is returned from the heatexchanger to the valve body 2 through a further connection and thence through the by-pass connection 4.

Electric and magnetic sound-boxes; soundboxes, arranging and supporting.-In sound-reproducing apparatus of the kind claimed in the parent Specification, a sound record is reproduced by means of a non-resonant electrodynamic generator actuated directly by a stylus attached to the armature of the generator, thereby deriving an electric potential which is the differential of the wave form of the vibration of the stylus. The potentials so obtained may operate valve circuits, of which the output frequency characteristic is under control, for working a loud-speaker. The generator may consist of a reed type telephone receiver, suitably modified as shown for example in Figs. I and II. The armature is a reed 120, provided with a fin 121 which carries the diamond or sapphire for engaging the record, the reed being mounted on a torsional elastic pivot 289. As described in Specification 190,759, the interior of the shell of the reproducer may be filled with grease or petroleum jelly. The reproducer is supported in a ring 288, swivelled on a bracket 284 which is secured to a standard 285, the record cylinder being fed under the reproducing-point. Figs. III and .IV show a generator of the moving-coil type. An E- shaped permanent magnet 7 has polar extensions 9 between which is located a stiff armature-coil 1 carrying a stylus 3 (or two styli, as shown, for use optionally with lateral-cut or hill-and-dale records). The coil is adapted to vibrate about an axis determined by a stiff spring 281, and may consist of a large number of turns of insulated wire. Wooden blocks are inserted in the coil at either end, the central pole of the magnet being surrounded by the coil.

Title: Process for producing gasoline of improved quality
IPC: C10L1/06
Filed: 1960-06-23
Abstract: Gasoline is upgraded by distilling to separate C5 and C6 hydrocarbons from the C7 +, catalytically reforming the latter and distilling to separate from the reformate C5 and C6 products from C7 + products, passing the C5 and C6 reformate with a recycle stream through a molecular sieve adsorbent to separate normal paraffins from other hydrocarbons which latter are blended with the C7 + reformate to form the product, recovering normal paraffins from the sieve and isomerising together with at least the normal paraffins in the C5 and C6 feed hydrocarbons and returning the isomerisate to the sieve as the recycle stream.  In a modification the C5 and C6 reformate may be isomerised before passing through the sieve.  The total C5 + C6 feed stream may be passed to the isomerisation or it may pass first through the sieve.  If desired the desorbed stream of normal paraffins from the sieve may be separated into C5 and C6 streams which are isomerised separately, the n-hexane being processed at a lower temperature.  The C7 + feed stream may have an end point of up to 232 DEG C. and is reformed over a platinum catalyst, preferably in 3 or 4 reaction zones, at 427-566 DEG C., 6.8-68 atmospheres, 0.5-10 vol./vol./hr., with 0.5-20 mols of hydrogen per mol of hydrocarbons.

Sorption on the molecular sieve, which may be a zeolite of pure size 4 or 5  , may be effected in the vapour or liquid phase, and desorption effected with a heated gas, e.g. nitrogen, steam or propane at 100-900 DEG C., or with liquid butane.
