Abstract: 1474622 Making cylindrical plastics sleeve; searing OWENS ILLINOIS Inc 24 April 1974 [25 April 1973] 50892/76 Headings B5A and B5K A cylindrical sleeve of plastics material is made by wrapping a sheet around a mandrel with the ends of the sheet overlapping, directing hot air between the overlapped ends to soften their facing surfaces, diverting the air away from the ends after softening has occurred, and finally pressing the ends into engagement to form a longitudinally extending seam by means of a sealing bar. The sleeve thus formed may be used in a process and apparatus for the manufacture of containers as disclosed in Specification 1,474,621. In the above mentioned application rectangular blanks are cut from a continuous sheet, separated, and fed to an assembly for making sleeves. The sleeves are transferred to a series of mandrels which form a station at which discs are applied to the ends of the mandrels. The mandrels subsequently pass a heating station, a station at which the discs are sealed to the ends of the sleeves which have been heat shrunk on to the mandrels, a station at which the containers thus formed are removed from the mandrels and rimmed, a pre-heating station, before returning to the sleeve applying station for a new cycle (see Fig. 5, not shown). In the preferred embodiment, the leading end of a blank 18 (or 118) is held by a vacuum slot 35 on a rotating mandrel 31 (131), rotation of the mandrel through 540 degrees causing the blank to wrap around the mandrel with its ends overlapping as in Fig. 8. During the wrapping operation the blank is held firm against the mandrel by a roller 436 and at the end of the wrapping operation hot air is directed from an elongated nozzle 427a (427) between the overlapped ends. Finally the hot air is diverted and a cold sealing bar 429 forwarded to effect a seal. A series of mandrels are located on a rotating turret and after a sleeve has been formed on each mandrel the turret moves the mandrel to a path coinciding with the path of mandrels upon which the sleeves are shrunk to shape. The nozzle 427 associated with each mandrel 131 is located at the upper end of a vertical hot air duct 428 and has an air diverting opening 427b selectively opened and closed by a pivoted cover 428 actuated by a spring biased link system 428h actuated by a follower 428m which runs around a fixed cam 428n. Each roller 436 and sealing bar 429 is mounted in a carriage assembly 435 carried at the end of a forwardly spring biased piston rod 430 the rear end of which engages a fixed cam 430b through a cam follower 430a. The roller is biased forwardly of the bar relative to the carriage assembly by a spring 437 so that when the carriage assembly is first forwarded only the roller contacts the sleeve and when the assembly is further forwarded the pressure of the roller is increased and the sealing bar is brought into operative contact with the sleeve.

Abstract: A device for electronically controlling the intake air temperature of an internal combustion engine, featuring a temperature sensor in the clean air space of the filter, the signal from the sensor controlling an electromagnetically driven oscillator pump whose vacuum output adjusts the flapper of an air flow proportioning valve by means of a pneumatic actuator, until the correct ratio of cold and preheated raw air is admitted into the intake system for the establishment of an optimal combustion air temperature. An automatic lowering of this temperature under full-load operation is achieved by utilizing the negative pressure in the air intake manifold as a control means to shift the oscillating armature of the oscillator pump away from its maximum output position. In an air intake system for fuel-injected engines, a similar result is achieved by means of an air flow sensor whose output signal is superimposed on the control signal from the temperature sensor.

Abstract: The invention relates to a method and apparatus for measuring at least one of the parameters flow rate, flow velocity, concentration and quantity of radon and/or radon daughters in the ground. The method is characterized by collecting gas arriving from the ground in a first chamber which is gas-permeable at the bottom thereof, at least the downwardly extending boundaries of the chamber being in contact with the ground, so that atmospheric gas is prevented from passing into the chamber. At least one detector which measures alpha-radiation from the decomposition of radon and radon daughters is placed in a second chamber communicating with the first chamber. Positioning of the second chamber and the detector is selected so that the detector can continuously be observed and utilized for the measuring operation. The gas is allowed to pass continuously. through the chambers over a given period of time, to expose the detector to the gas. Subsequent to this exposure, the measuring result registered on the detector is evaluated. The method can be modified for measuring radon departure from the surface of the ground, the gas-permeable first chamber being arranged over the surface of the ground to be analyzed. The detector is placed in a second chamber communicating with the first chamber. For the purpose of measuring the flow rate and velocity of radon passing through the ground there is provided a first chamber beneath the level of the ground, at a desired depth. This first chamber is connected with a gas-impermeable passage to a second chamber which can be readily reached from the level of the ground and which is sealed against penetration of atmospheric air. The detector is placed in the second chamber.
