Title: Dosimeter charging apparatus
IPC: H01R13/646
Filed: 1963-10-08
Abstract: Apparatus into which a dosimeter can be plugged for charging purposes comprises two members engaged by the dosimeter, one in the form of a sleeve surrounding the other, and one being spring-loaded and arranged, when moved by the dosimeter against its spring, to cause a charging voltage to be connected across the members. The dosimeter has a central contact 38, which engages a fixed contact 22 of the charging apparatus and is surrounded by a tube 39 for co-operation with a spring-loaded sleeve 23 having two steps to fit different dosimeter tubes 39. When the dosimeter is pushed into the charging apparatus, the sleeve 23 is depressed and a rod 31 carried thereby closes a switch to energize the charging circuit and a light which shines through the transparent body in which the contact 22 is mounted. The socket for the dosimeter may be normally closed by a removable cap. The charging circuit is energized by a battery 12 when the switch 42 is closed by the rod 31. It comprises a transistor oscillator, the H.T. output of which cuts through a rectifier 47 to charge a reservoir condenser 48. A potentiometer 50 enables the effective charging voltage applied across the dosimeter contacts 22, 23 to be adjusted.

Title: Gear train assemblies
IPC: F16H57/02
Filed: 1967-05-23
Abstract: In a gear train comprising driving and driven gear-wheel units 4, 5 (Fig. 2), the distance between their axes of rotation being variable, connected by an idler gear unit 12, each unit comprising a gear-wheel 8, 10, 13, and at least one coaxial cylindrical spacer 9,11, 14, the spacer 14 of the idler unit being in rolling contact with those of the driving and driven units when the gear teeth are in correct mesh, the relative disposition of the units is such that the resultant of the forces applied to the idler gear teeth acts in a line passing between the axes of rotation of units 4, 5 to hold the idler teeth constantly in correct mesh with those of the driving and driven gears. This is so when the angle between a line through the axes of rotation of the units 4, 12 and a line through the axes of rotation of the units 5, 12 is greater than twice the pressure angle of the meshing gear teeth. The spacers have diameters equal to the pitch circle diameters of their respective gear-wheels and are integral therewith. To retain the idler unit when stationary, or on overrun, a spring 15 may be used, or a slipper block (22) (Fig. 6, not shown), or a fixed peg (19) within an annular idler unit (18) (Fig. 5, not shown). If the axes of the units 4, 5 lie substantially in the same horizontal plane and the idler is above them, gravity suffices. In Fig. 7, a belt 29 round pulleys 30, 31 forming axial extensions of the driving and driven units 25, 26 prevents relative rotation of the latter when they are unloaded, to prevent the idler unit 24 from falling out of mesh. In Fig. 8 (not shown) an idler (12) is carried on an arm (34) pivoted on the shaft (6) of the driving unit (4) for use in opposite directions of rotation, a friction coupling between the arm (34) and the shaft (6) moving the idler from one drive position to the other when the drive is reversed. In Fig. 11 the pitch circles of the driving and driven units 35, 40 overlap, the unit 35 having two gear-wheels 36 spaced apart and the spacers 43 of the unit 40 being axially spaced from the gear-wheel 41. Gears 36, 41 mesh a wide idler gear (46) (Fig. 10, not shown). In Fig. 13, a driving unit 52 lies within an internally toothed annular driven unit 49 and is connected thereto by an idler unit 53. The gears may be of metal, rubber, or plastics

Title: Process for crystallization,drying and solid-state polymerization of polyesters
IPC: B29B13/06
Filed: 1969-02-05
Abstract: Crystallised polyester pellets are simultaneously dried and solid-state polymerised by passing them continuously through a vessel 47 in countercurrent to a heated inert gas. Polyester which has been either pelletised and crystallised in a fluidised bed enters at the top of vessel 47 and falls as a bed under gravity, the pellets being removed at the base of the vessel by discharge rotary valve 58. The inert gas is first heated to a temperature of from 160 to 212 C in heater 43 and then enters vessel 47 via plenum chamber 46, leaving via chamber 51. The gas velocity is kept below fluidization rates (below 2.1 ft/sec.). A level controller 50 is provided for controlling the residence time of the polymer in the vessel. The vessel should preferably have a height of at least six times its diameter and a cross-sectional area of at least twice that of the fluidised crystalliser used in the preceding step. Specified dimensions for the vessel are given in Examples 7-10.

Patent ES-414157-A1 (ES)
Title: Method and apparatus for treating carbureted mixtures
IPC: B03C3/02
Filed: 1973-04-27
Abstract: A mixture of air, water vapor and droplets of fuel, such as a hydrocarbon type, is treated to assure complete combustion of the fuel to thereby minimize polluting emissions by passing the mixture through an electrostatic field in a heat exchange chamber having reduced pressure. Exposure to the field relaxes the surface tension of the fuel droplets to increase vaporization thereof, and physical contact of the mixture with heat exchange structure during fuel vaporization causes the water vapor of the mixture to condense for separation from the air and fuel vapor. One embodiment has concentric tubular electrodes which house the outlet for fuel vapor and air to prevent remixing of water condensation therewith, and a second embodiment has superimposed, plate-like electrodes which shield the fuel vapor and air outlet from water condensation and serve to break up fuel droplets by forcing the same to follow a tortuous, serpentine path through the field.

Title: Apparatus for producing vacuum skin packages in multiples
IPC: B65B11/52
Filed: 1974-01-22
Abstract: Thermoplastic film is drawn by differential air pressure against a multiplicity of concave interior surfaces of the upper portion of a vacuum chamber the film is then heated by surface contact then, after evacuation of the chamber in which has been placed a multiplicity of products spaced upon a backing board, differential air pressure is used to blow the film down over each of the products and against the backing board completely around each of the products thereby sealing the film to the board and, subsequently, the board and film are cut to provide a multiplicity of individually sealed, vacuum skin packages. By this method and apparatus the prior art problem of "draping" and "webbing", i.e., the failure of the film to contact the board or seal to itself between relatively tall, adjacent products, is eliminated.

Title: Process and apparatus for seasoning wood
IPC: F26B7/00
Filed: 1974-09-16
Abstract: A process and apparatus for accelerated drying of green lumber employs high voltage dielectric heating at subatmospheric pressure to effect a rapid removal of moisture from the wood without splitting, checking, case hardening, honeycombing or similar damage to the wood structure. The invention combines the advantages of both dielectric and vacuum drying techniques without inefficient and destructive corona, arcing, or ionization effects which have heretofore prevented combining such techniques. When desired, the use of subatmospheric pressures in the drying process also permits injection of suitable chemicals for fireproofing or other specialized treatments of the wood allowing the combination of such treatments with the drying of the wood in a single process.
