Abstract: 680,001. Vacuum pumps. EDWARDS & CO. (LONDON), Ltd., W., and BARRETT, A. S. D. Oct. 12, 1949 [Oct. 12. 1948], No. 26505/48. Classes 110 (i) and 110 (ii) [Also in Group XXVIII] A method of obtaining a high vacuum in a container consists in employing a large volume displacement mechanical pump 2 capable of a minimum displacement of 100 cu. ft./min. and operating at high speed without rubbing contact, together with a mechanical backing pump 1 or an ejector. The large volume displacement pump 2 may be a Northey compressor, a Rootes blower or a centrifugal blower or piston and cylinder pump and the pump 1 a rotary pump. The pump 2 may be immersed in a tank containing a low vapour pressure liquid which may be maintained at sub-atmospheric pressure e.g. by connecting it to the pump 1. The pump 2 may be sealed by a film of sealing liquid. A pressure relief valve 5 may be inserted in the line between the pumps 1, 2 and the line may have a cooled trap 25 and a pressure responsive switch 26 to switch off the motor driving pump 1. Pump shaft seals on the pump 2 may be connected to the pump 1 to prevent ingress of lubricant to pump 2. The system may be used to back a vapour steam pump.

Patent GB-463122-A (GB)
Title: Recovery of sulphur
IPC: C01B17/06
Filed: 1935-09-28
Abstract: <PICT:0463122/III/1> Sulphur is obtained by subjecting iron sulphide to high temperature oxidation to produce iron oxide and gases containing sulphur dioxide which are then passed through a porous charge of pyrites and solid carbonaceous material to effect removal of the labile sulphur from the pyrites and reduction of the sulphur dioxide to sulphur, preferably the iron sulphide remaining then being oxidized as above.  The iron sulphide may be oxidized in suspension or in the form of a molten bath, and the pyrites and carbonaceous material may be in the form of a solid bed or be treated in suspension.  In the arrangement shown, a mixture of finely divided pyrites and carbonaceous material is fed into distillation and reduction chamber 12 from a hopper 51 and is there treated in suspension with the hot gases from the oxidizing chambers introduced through tuyeres 55.  The gases containing sulphur pass through a dust collector 15, water-cooled condenser 16, preferably maintained at 115--150 DEG  C. and finally through an electrical precipitator 19. The solid product, mainly iron monosulphide, is passed via conveyer 20 to the molten bath oxidizing chambers 10 and 11.  Oxidation is effected by air blown in through tuyeres 30 and 31, such air preferably being preheated by the hot reaction gases in heat-exchangers 13 and 14.  The iron sulphide may be introduced into the chambers 10 and 11 over an extended period until they are full, and when the oxygen content of the gases leaving a chamber increases, such gases are passed in series through another chamber containing a charge of higher sulphur content, or preferably the operation of the chambers is staggered so that they are charged and tapped at different times, thus ensuring continuous operation.  The oxidation is carried out to produce gases at over 1000 DEG  C. and containing substantially no free oxygen.  When suspension roasting is used, the monosulphide is preferably ground to minus 40 mesh before oxidation.

Title: Fringe forming sewing machine
IPC: D05B35/06
Filed: 1960-08-08
Abstract: 888,305. Sewing machines. FEIGHERY CO. Inc., J. M. Aug. 8, 1960 [Aug. 31, 1959; July 28, 1960], No. 27374/60. Class 112 A method of forming fringing loops comprises continuously blowing thread transversely of the line of stitching in a sewing machine, stitching a strand of the thread by the sewing machine while a thread loop forms outwardly of the line of stitching and forwardly of the machine needle, and subsequently stitching the inner ends of the successive loops thus formed. The thread issues from a guide carried at the lower end of a lever which is oscillated to move the guide back and forth from a point just behind the needle to a point forwardly thereof. A pair of shafts 18, 19 are journalled in plates 23, 31 attached at 24 and 32 to the standard and head respectively of a sewing machine. Shaft 18 is driven by a chain 16 from the bed shaft 14 of the machine, and shaft 19 is driven by gearing from shaft 18. A crank pin 64, carried by shaft 18, is coupled by a link 66 to the upper end of a lever 55 pivoted at 56 to an arm 57 fixed adjustably at 58 to the presser bar 35 of the sewing machine. The lower end of lever 55 carries a tubular thread guide 62 disposed adjacent a pair of needles 46, 47 carried by the needle bar 44, and just above the presser foot 36 formed in one edge with a notch 41 for the passage of the needles. Shaft 19 carries a roughened, threadfeeding wheel 81. A wheel 82 is pivoted at 88 on an arm 89 rigid with a shaft 90 which is spring- biased to urge wheel 82 against wheel 81, a handle 96 on shaft 90 enabling the wheels to be moved apart. Thread 80 passes between the wheels on its way through the tubular guide 62. A nozzle 70, carried by a bar 72 rigid with the lever 55, is connected to a flexible, compressed air hose 73, and is aligned with the thread guide 62, whereby air issuing from the nozzle assists the passage of the thread 80 through the guide 62. The arrangement is such that, as shown in Fig. 5, guide 62 in its rearmost position is between the needles 46, 47, and both limbs of the last-formed loop 109 are thereby secured to a tape 108 by the last-formed stitches of the respective seams 105, 113. Guide 62 then moves forwardly and the work is fed rearwardly, whereby the rearward limit of a newly-formed loop and the forward limb of loop 109 are respectively secured by the next stitches. Both limbs of the newlyformed loop are secured when the guide 62 returns to its rearmost position.
