Title: Process for trimming the neck of hollow articles in plastic material and device for carrying out the process
IPC: B29C49/74
Filed: 1965-12-29
Abstract: 1,079,579. Deflashing of hollow bodies. SOLVAY & CIE. Dec. 29, 1965 [Dec. 30, 1964], No. 55057/65. Heading B5A. The necks of hollow bodies of plastics material are deflashed after removal from the mould and cooling, by cutting through the flash with a fixed cutting blade while moving the bodies continuously along the length thereof between a fixed guide and a movable guide gripping the bodies at the level of their necks, and rotating them simultaneously about their longitudinal axes. The apparatus, e.g. as shown in Fig. 1, comprises a device driving the bodies constituted by a fixed guide (8) and a movable guide (e.g. belt 3), which grip the bodies at the level of their necks, displacing them transversely with respect to their longitudinal axes and simultaneously rotating them about their longitudinal axes, and a fixed, but adjustable cutting blade (9, see also Fig. 3, not shown), disposed obliquely to the path described by the longitudinal axes of the bodies and perpendicularly to these axes, preferably fixed on the fixed guide. A feed corridor (11) may feed the bodies to the deflashing apparatus. The apparatus may be operated in either the vertical or the horizontal position.

Title: Improvements in or relating to Light Beam Communication Systems
IPC: H04B10/112
Filed: 1966-12-09
Abstract: 1,173,439. Optical communication system. NIPPON ELECTRIC CO. Ltd. Dec. 9, 1966 [Dec.15, 1965], No.55382/66. Heading G1A. In an optical communication system, a number of light beams, representing different communication channels, are received by a common optical receiver which focuses the beams on to the appropriate ones of an array of photo-electric detectors, the separation of neighbouring detectors such as to ensure that the corresponding beams which they receive may be distinctly separated from one another even when there is atmospheric turbulence which might cause spreading of the beams. Fig. 1 shows one arrangement of the optical receiver, in which a concave mirror 11 focuses light beams 13, 13' from different transmitters on to different units 14, 14' of an array of photoelectric detector units 20. Each of the units, illustrated in detail in Fig.2, comprises a box having an aperture 24 through which light reached a p-n, or p-i-n junction-type diode detector, mounted on the back, inside wall of the box. The boxes provide electrical and optical screening for the photo-diodes. In an alternative arrangement, the photo-diodes may be formed in a single wafer. The transmitting sources for producing light beams such as 13, 13' are lasers e.g. of the Helium- Neon or Argon type. Light from each laser is modulated with the information to be transmitted and collimated by a Galilean telescope optical transmitter, Fig. 5 (not shown) which may be directed as required. In a multi-channel communication system, each receiver is associated with an array of transmitters arranged around it and a number of arrangements such as this associated with one another in a coordinate array, Fig. 3. The two identical arrays are mounted on the roofs of respective buildings providing multi-channel communication between them. In such a system, a receiver of a particular transmitter-receiver arrangement of one array, receives beams from widely separated transmitters of different transmitter-receiver arrangements on the other array, thus providing distinct angular separation of the beams through the atmosphere. Examples of beam path configurations are illustrated in Figs.6 and 7 (not shown). Alternative optical receivers employing a polyhedral mirror, Fig. 8 (not shown), and a dichroic mirror Fig. 9 (not shown), to achieve spacial division of the beams, are described. Photo-multipliers may be used instead of photodiodes.

Title: Apparatus for adsorption m'surement

Filed: 1970-12-10
Abstract: 1315986 Adsorption measurements EUROPEAN ATOMIC ENERGY COMMUNITY 10 Dec 1970 [10 Dec 1969] 58656/70 Heading G1S The adsorption of a gas in a porous solid is measured by introducing equal quantities of the gas into contact with the solid in successive stages. During any particular stage valve 8 is open and valve 7 closed, and the equilibrium pressure attained over the sample in bulb 1, which is also the pressure in chamber 5, is transmitted via tube 4 to one arm 25 of a monostat. Adsorbate gas is introduced continuously at 19 to the other arm 6 of the monostat which includes a tube 22 connected at its upper end to a vacuum pump and covered at its lower end by a sintered glass disc 24. Consequently the monostat maintains the pressure of gas in arm 6 and in tubes 21 and 17 at a predetermined pressure P above that in the bulb land in the chamber 5. To introduce a further quantity of gas into contact with the solid valve 8 is closed, valve 7 opened then closed and valve 8 opened again. Thus while valve 7 is opened a further quantity of gas PV (V being the volume of chamber 5) is added into chamber 5 and hence into contact with the sample in bulb 1 when valve 8 is opened. The pressure in chamber 5 is measured during the adsorption by a pressure transducer 10 and recorded. Signals from transducer 10 may be passed to a computer which calculates the BET surface area and the pore size distribution. The temperature of the system is maintained constant, and the sample in bulb 1 may be cooled by a cooling liquid in a Dewar device. Valves 7 and 8 may be operated automatically by a pair of clocks which turn each other on and off. A counter may be provided to count the number of stages and may be arranged to connect the space between valves 15 and 7 to vacuum via valve 15 after a predetermined number of stages to measure the desorption of the gas.

Abstract: 1,235,207. Labelling machines. H. KRONSEDER. 12 Dec., 1968 [20 Dec., 1967], No. 59157/68. Heading B8F. Labels are removed from a stack by a transfer element which is circulated bodily around a hypotrochoidal path. In one preferred embodiment the path is generally triangular, in another it is elliptical. As shown, a transfer element 10 is rotatably mounted in an arm 8 fast with a planet gear 5 mounted in a driving carrier 3 and meshing an idler planet 7 which meshes a stationary sun gear 1. The ratio of the sun 1 to the planet 5 is 3 : 1 and the length of the arm 8 is a quarter of the spacing between the axes 2, 4 of the sun 1 and planet 5, to give a generally triangular path for the transfer element 10. In order to obtain the same position relative to a line through the axis 2 and the axis 9 of the transfer element for suction nozzles on the surface of the element at each corner of the triangular path, a gear 11 may be fast with the carrier 3 and mesh a gear 12 fast with the transfer element, a gear ratio being 4 : 3. Alternatively the gear 11 may be rotatable on the carrier and be fast with an arm of a cam follower engaging an appropriately shaped stationary cam. The transfer element may encounter a gluing band prior to picking up a label. Preferably the labelling cylinder, to which the labels are transferred by the element 10, is adjacent a corner or relatively curved section of the element's path and the label stack is adjacent a relatively straight section of the path.
