Title: Improvements in or relating to Syringes
Inventor: PITT PETER
IPC: G01N30/18
Filed: 1967-05-23
Abstract: 1,167,408. Injection syringe for chromatography. SHANDON SCIENTIFIC INDUSTRIES Ltd. 5 April, 1968 [23 May, 1967], No. 23955/67. Heading B1L [Also in Division F1] A metering device for use with a syringe in chromatography comprises a body member for attachment to the syringe barrel, a head member for attachment to the outer end of the syringe plunger and mounted for movement towards and away from the body member, and a pin on one of the members extending parallel to the direction of movement so that it can engage a movable abutment on the other member to maintain the members a predetermined distance apart, the abutment being movable into a position in which it is out of the path of the pin so as to permit the members to be moved together by means such as a spring or springs or pneumatic means so as to expel a predetermined amount of fluid from a syringe mounted in the device. The syringe barrel 12, Figs. 1 and 2, is secured to a block 18 constituting the body member by a clamping collar 28 and an O-ring 26, while the finger button 64 of the plunger 16 is secured to a block 60 constituting the head member by means of a pad 76 which is pressed by a leaf spring 70 against the button so as to hold it against a slotted disc 68 which is seated on an annular flange 66. Movement of the block 60 towards the block 18 is effected by a constant-tension coil spring 37 and guided by slider rods 42 on the block 60 passing through guide tubes 40 in the block 18. A screw-threaded pin 81 screwed into the block 60 and bearing against an abutment disc 46 carried by the block 18 is adjusted until the tip of the plough 16, as viewed through the transparent barrel 12, is at the required calibration, and locked by a nut 84. Switch contacts 98, 100 in a pistol-grip handle 56 are then adjusted by turning a boss 94, Figs. 1 and 3, carrying the contact 98 so that the contacts close at some predetermined point during injection, preferably at the end of injection, and a clamping screw 95 is then tightened. To load the syringe, the disc 46 is pivoted about its pivot screw 48 by means of a trigger 52 to bring an arcuate cut-out 50 in the path of the pin 81 so that the plunger 16 can be pulled into the syringe. The block 60 is then pulled away from the block 18 until the pin 81 is clear of the disc 46 which is then returned to its former position. The block 60 is then released so that the spring 37 expels surplus liquid from the syringe until the pin 81 again engages the disc 46. After introduction of the syringe needle into a carrier gas flowing towards a chromatograph separation column, trigger 52 is turned to free the disc 46 from beneath the pin 81, and the constanttension spring 37 discharges the liquid at a constant rate into the gas. Towards the end of the discharge, the contacts 98, 100 close (or, in a modification, a microswitch closes) to start a chromatograph recorder or provide an event mark on the recorder trace.

Title: Storage of produce
IPC: A23B7/148
Filed: 1966-05-27
Abstract: Fruit (other than green bananas) of the type having, during ripening, a climacteric rise in respiration rate which in normal air at room temperature reaches a peak leading to the onset of senescence within seven days of the onset of the climacteric rise, is preserved by sealing a portable weight of the fruit, subsequently to onset of the climacteric but prior to onset of senescence, in imperforate sheet material (e.g. low density polyethylene film) of such permeability to oxygen and carbon dioxide in the thickness used and of such area relative to the weight of the packed fruit, and with such restricted initial content of air in the package, that continued respiration of the sealed-in fruit will initially establish and thereafter maintain within the package a controlled atmosphere of less than normal oxygen content and greater than normal carbon dioxide content and so reduce the rate of respiration and delay complete senescence of the fruit. The thickness of the sheet material used varies according to the particular fruit being preserved.  Surplus air is removed from the packages before sealing by means of suction or by immersing the packages in an incompressible fluid such as water. Fruit exemplified are tomatoes, melons, cherries, blueberries, papayas, peaches, nectarines, plums, mangoes and ripe bananas.

Title: Improvements relating to the treatment of acid sludge or acid resin obtained from the refining of mineral oils
IPC: C01B17/92
Filed: 1926-10-04
Abstract: 279,613. Jubb, J., (Pickering, J.). Oct. 4, 1926. Liquid fuel; mineral and tar oils. - Sulphuric acid and neutral sludge are obtained from the sludges produced in refining mineral oils with sulphuric acid or oleum by dissolving the heated and stirred sludge by spraying thereon an organic solvent capable of mixing with water, with an aqueous solution, and with sulphuric acid, and treating the solution with water or an aqueous solution in which the sludge is not directly soluble. In an example 100 lb. of sludge containing 35 per cent of sulphuric acid is agitated in the steam-jacketed tank 1 until dissolved in 300 lb, of acetone sprayed through a perforated pipe 5 while the temperature is maintained at least 5‹ C. below the boiling point of acetone. The solution is run into a similar tank 9, treated therein with 350 lb. of water or aqueous solution of common salt or sodium carbonate, and the temperature raised to distil off the acetone to a condenser 30. After settling, the acid is run off through a valve 25, freed from any remaining acetone, and concentrated for reuse. The sludge in the tank 9 is then washed, at a temperature below 100‹ C. but above the boiling point of acetone, with dilute sodium chloride or carbonate, separated, and heated to about 125‹ C, to remove the last traces of acetone and water. The washing liquid is used repeatedly until sufficiently enriched with acetone as to be used in the tank 1 directly or after concentration. The neutral sludge can be used as a pitch, as an asphalt pitch when mixed with mineral oil, as a substitute for resinous or asphaltic bodies in lacquers, varnishes, insulating material, and printing inks, in impregnating and binding materials, e.g. for briquettes, as a liquid fuel when mixed with mazout, and as a rubber substitute when mixed with distillation residues of mineral oil or vegetable or animal products.
