Title: High-frequency dielectric heating apparatus
IPC: H05B6/62
Filed: 1949-10-05
Abstract: 673,549. Seaming non-metallic sheet material. COMMUNICATIONS PATENTS, Ltd., BAZIN, R. E., and DOWNING, R. K. Jan. 5, 1951 [Oct. 5, 1949], No. 25645/49. Class 42 (i). [Also in Group XI] A high-frequency dielectric heating apparatus for producing a number of welds simultaneously in the overlapping portions of a pre-folded traylike structure of sheet material, includes a number of relatively movable sections each having electrode means of a separate electrode system, and electronic valve means whereby the electrode means is energized. In the embodiment shown a pedestal 4 supports a work-table 5, and accommodates a power supply for separate oscillator sections 7, and the latter, which carry pairs of electrodes 12, 13 are adjustable along a slot 9 in a support 6 by screw-threaded rods 10. The latter engage nuts 8 secured to the sections and are rotated by wheels 11. The electrode pairs co-operate with a counter-electrode 17 which is moved towards them to clamp the work-piece between them, and to effect two welds simultaneously.

Title: Improvements in or relating to apparatus for degasifying liquids
IPC: B01D19/00
Filed: 1934-09-06
Abstract: <PICT:0422773/III/1> <PICT:0422773/III/2> The apparatus described in the parent Specification for degassing liquids while in the form of thin sheets with large areas, is subdivided into two or more sections placed vertically in casings, such as 1<1>, 1<11>, which form one body with a liquid collector 2 at its lower end.  The casings 1<1>, 1<11> contain cones 3 rotated by the spindle 5 and alternating with the fixed cones 4.  The U-shaped tube 7 allows liquid to pass from the upper section to the lower one, but does not allow gas to pass in the reverse direction.  Liquid is fed through the tubes 14, 15 to the first cone 3 of the upper section and is spread over the cones on its downward travel.  It then passes through the tube 7 and the lower section 1<11>.  Air pumps attached to the pipes 6<1>, 6<11> maintain low pressures to assist in the degassing process.  The liquid collects in the section 2 and eventually raises the float 12 to cut off the supply of liquid to the apparatus.  A collar 10 slipped on the spindle has a flange 11 resting on the base 9 of a cavity in the wall 8 between the sections 1<1>, 1<11>.  This cavity becomes filled with liquid which prevents gas from passing between the sections.

IPC: C07C45/33
Filed: 1960-07-25
Abstract: A mixture of cyclododecanone and cyclododecanol is prepared by oxidising cyclododecane in the liquid phase with molecular oxygen at a temperature of 90 DEG  to 150 DEG C.  An oxidation catalyst such as the heavy metal salt of a fatty acid or a naphthenic acid e.g. the stearate, 2-ethyl-hexanoate or napthenate of cobalt or manganese is preferably present, and oxygen or air is injected into the cyclododecane containing the catalyst in suspension, in a continuous or discontinuous process.  A conversion of from 5 to 20% is preferred and the mixture of ketone and alcohol may be separated from the other oxidation products by distillation, and the mixture separated by in vacuo distillation or by the separation of the ketone as oxime. Dodecanedioic acid may be prepared by the nitric acid oxidation of the separated cyclododecanol or of the oily residue from the process and the lactam of aminoundecanecarboxylic acid may be prepared from the cyclododecanone.

Filed: 1959-07-31
Abstract: 907,511. Mass spectrometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 4, 1960 [July 31, 1959], No. 26450/59. Class 39 (1). In a method of detecting ions, e.g. in mass spectrometry, the ions strike a thin foil of such thickness that only desired ions can penetrate to the back surface of the foil to liberate secondary electrons which pass to an electron detector such as a scintillometer. In this way it is possible to distinguish between ions of the same mass and charge but having different numbers of constituent nuclei, e.g. H 2 + and D+ ions, H 3 + and HD+ ions or He+ and " air " ions, or, according to the Provisional Specification, atomic and molecular potassium ions. In Fig. 1, a thin aluminium foil is supported on a nylon film 14 which is transparent to secondary electrons. The foil is mounted in a polished stainless steel holder 12 and receives ions passing from a mass spectrometer through the slit 4 in a plate 3. Holes 5 are pumping holes. The secondary electrons liberated at the back surface of the disc 14 pass through a slit 13 in the holder 12 to a scintillometer comprising an organic scintillator 8, e.g. polystyrene, and a photomultiplier tube 11. A layer of aluminium 0.05 Á thick is provided on the surface of the scintillator and a silicone oil provides good optical contact between the scintillator and the photo-multiplier. The holder 12 is held at a high negative potential to accelerate both the ions on to the disc 14 and the secondary electrons away from the disc. An anti-corona ball 21 is provided on top of the glass metal seal 16. In Fig. 2, the ions 27 are accelerated on to the disc 14, secondary electrons 28 liberated at the back surface are detected by scintillator 8 and photo-multiplier 11 while secondary electrons 29 liberated at the front surface are detected by scintillator 8<SP>1</SP> and photo-multiplier 11<SP>1</SP> to provide a measure of the total number of ions in the beam 27. An anti-breakdown polystyrene guard ring 25 is fixed on the insulator 26 containing the lead 22. An aluminium foil may be prepared by vacuum coating on glass and then floating off in water and lifting on a small ring which is push fitted in the holder. A carbon or gold foil may be used.

In a continuous cycle absorption refrigeration system employing a paraffin hydrocarbon having seven or more carbon atoms per molecule as the absorbent and a paraffin hydrocarbon having three or four carbon atoms per molecule as refrigerant, heat exchange in the generator 1, condenser 2, evaporator 3 and absorbent cooler 5 is effected by direct contact. The generator 1 is heated by hot water or steam supplied by a pump 9 and refrigerant vapour is condensed by water supplied to the condenser from a cooling tower 7 by pumps 8 and 10. The liquid refrigerant then passes through a throttle valve 12 to the evaporator 3 where it cools water supplied by pump 8. The absorber 4 is cooled by water supplied by pump 8 and is supplied with absorbent from the cooler 5 via a throttle valve 13, the cooler 5 being supplied with cooling water by pump 10. The water from components 2, 4 and 5 is freed from hydrocarbons in a column 6 by direct contact with methane before being returned to cooling tower 7. Examples of operating conditions are given. Propane hydrates which may form in the system are decomposed by electrolytic aqueous solutions supplied direct to the evaporator and throttle valve 12. The refrigerant and absorbent may each comprise a mixture of hydrocarbons.
