Title: Improvements in and relating to the manufacture of sulpholenes and sulpholanes
Inventor: BLANCO JOHN RODRIGUEZ
IPC: C07D333/48
Filed: 1965-06-29
Abstract: Preparation of a sulpholene by reacting a 1,3-alkadiene, e.g an alkadiene containing 4 to 6 carbon atoms, with sulphur dioxide in a liquid reaction medium comprising a solvent for sulphur dioxide and the 1,3-alkadiene wherein the amount of unreacted 1,3-alkadiene and/or sulphur dioxide in the sulpholene-containing product is reduced by stripping the reaction product with the said solvent in vapour form, and the vapours resulting from the stripping are condensed and returned as a liquid condensate to the liquid reaction medium.  If desired the sulpholene-containing reaction product may be subjected to conditions of pressure and elevated temperature such that a proportion of the unreacted 1,3-alkadiene and/or sulphur dioxide contained in said reaction product is flashed off as vapour therefrom prior to the above stripping step.  The flashed-off vapour may be combined with the vapours resulting from the stripping. The process may be carried out in continuous or batchwise manner by reacting the sulphur dioxide and butadiene under pressure at a temperature in the range 70-120 DEG  C., optionally in the presence of an anti-oxidant, using an aliphatic alcohol, preferably iso-propanol, as solvent. The reaction product is preferably stripped, with or without prior flashing off of vapour therefrom, at a temperature between 80 DEG  and 90 DEG  C. under slightly elevated pressure by downward passage through a vertical column having internal packing or baffles wherein vaporized solvent is supplied to the base of the column and the vapours from the head of the column together with those from the optional prior flash evaporation step are condensed for re-use.  The resulting sulpholene may be catalytically hydrogenated, after an optional treatment thereof with a minor proportion of hydrogen peroxide and alkali, to give the corresponding sulpholane using, for example, Raney nickel catalyst which is added to the alcoholic solution of the sulpholene at or below the hydrogenation temperature.  The preparation of 3-sulpholene and sulpholane is described.

Patent GB-211530-A (GB)
Title: Improvements in or relating to the production of metallic coatings on refractory material
IPC: C04B41/51
Filed: 1922-10-16
Abstract: Relates to a process for obtaining catalytic surfaces in the form of metallic coatings on the surface of bodies of refractory materials, such as earthenware, clay, glass, porcelain, &c. which contain metallic oxides reducible by metals of the alkaline earth or light metal groups.  The refractory body is embedded in a mixture of a pulverized alkaline-earth metal, for example magnesium, and its oxide, or a mixture of a pulverized light metal, for example aluminium, and its oxide, or a mixture of the two pulverized metals and their oxides, and submitted, in a hydrogen atmosphere, to a temperature above the melting-point of the pulverized metal but below the melting-point of the refractory body.  The metal vapours generated reduce to metal the metallic oxides of the refractory material where these are accessible to the vapours.  The parts of the refractory material which are not to be submitted to the reducing action are protected by covering with the oxide of the alkaline earth or light metal employed for the reduction.  The catalytic surfaces may be formed on bricks which are made from a mixture of the refractory material and oxides, sulphides, or halogen compounds of the heavy metal which is to serve as the catalyst, these bricks being burnt and thereby made porous.  The porous bricks are subjected to the reducing process, whereby not only the outer surfaces but also the pores are coated with the reduced metal, the metals which are produced besides the catalyst being limited by appropriate selection of the refractory material.

Abstract: 1,007,939. Cables. FUJIKURA DENSEN KABUSHIKI KAISHA. July 20, 1962 [July 21, 1961; March 14, 1962], No. 28049/62. Heading H1A. In a coaxial cable the space between the concentric conductors is filled with an insulating layer of foamed synthetic resin having a film layer of synthetic resin of low melting point intimately cohering with its outer surface. The insulating separator material may be foamed polystyrene and the film layer may be of polyethylene. A process of manufacture is described (Fig. 4) in which a synthetic resin tape of low melting point 6 is coated with an adhesive 7 and is then covered with a layer of unfoamed or incompletely foamed synthetic resin chips 8, the assembly together with an inner conductor 9 and accompanied by part of an endless forming tape 14, e.g. of P.T.F.E., then proceeds through a forming die 11 in which the cable core is formed into a concentric construction prior to entry into a heater 13 in which the resin chips are foamed and the synthetic resin tape 6 is adhesively secured to the surface of the foamed resin. The tape 14 then separates off and the cable, core so formed may then proceed to a series of repeat operations (Fig. 5, not shown), wherein the core takes the place of the inner conductor in the assembly process and an outer concentric conductor which may be of copper tape is applied, to form a cable of larger diameter. Instead of synthetic resin chips in the unfoamed state, foamed synthetic resin sheet material may be employed (Figs 6 and 7, not shown), and it is also proposed that a copper tape, which ultimately is retained as the outer conductor, should take the place of the separate forming tape 14.

Title: Improvements in filled bag closing machines
IPC: D05B13/00
Filed: 1926-11-09
Abstract: 267,042. Armstrong, J. J. V., (Union Special Machine Co.). Nov. 9, 1926. Sach-sewing machines. - In a machine for closing filled bags in which the bag is conveyed to stitching mechanism by a carrier adapted to run back and forth on supports therefor, means, provided for returning the carrier to its starting or loading position, are operated by a control which also acts to render the return means inactive whilst the bag is being stitched. The return means operate at one point in the forward movement of the carrier and are held by manually controlled means in a displaced position where they are inactive during the forward movement of the carrier. The machine comprises a base 1, Fig. 1, and a column 3 carrying an adjustable collar 20 supporting a bracket 22. Mounted on the bracket 22 are angle irons 22<a> supporting longitudinal angle irons 24 fitted with horizontal rollers which constitute a track upon which a carrier is adapted to move to and fro. The carrier is formed with a lower plate which engages the rollers, and between this plate and an upper plate 25 vertical rollers are mounted to guide the carrier along the track. Adjustably mounted on the column 1 is a sewing head 5 adapted to draw the carrier along the track as it sews up; the end of a sack placed on the carrier. To return the carrier aiter the sewn sack has been removed, a bar 32, Fig. 3, disposed longitudinally of the track is pivoted near one of its ends to one of the angle irons 22<a>, the other end thereof being connected by a spring 38<1> to the outer longitudinal angle iron 24. The bar engages a roller 36 on a bell-crank lever 35 pivoted to the lower plate of the carrier and the roller is urged against the bar by a spring 37 which connects the free end of the bell-crank lever 35 to that plate. A link 41 connects the bar 32 to an arm 40 mounted on a spindle to which is secured a second arm 44 carrying a pulley wheel 45. Passing around this pulley is a flexible member 46 secured at one end to a fixed collar 17 on the column 3 and at its other end to a treadle 52, the member also passing around pulleys 48, 47 on the collar 20. When the treadle is depressed, the bar 32 is displacedto a position parallel to or slightly inclined towards the inner longitudinal angle iron 24, so that movement of the carrier by the sewing head 5 is either unaffected or slightly aided. When the treadle is released, the spring 38<1>, which is stronger than the spring 37, restores the bar to its initial position and thereby returns the carrier to its starting position. The treadle 52 is connected to the clutch 6 of the sewing head, which is thus controlled simultaneously with the return mechanism of the carrier. The arrangement of the pulleys 45, 47, 48 allows the collar 20 and bracket 22 to be adjusted on the column 3 without affecting the operation of the treadle, and similar means are employed in the connection between the treadle and the clutch 3 and between the sewing head and its motor, which is supported by. the collar 17.
