Patent EP-0000643-A2 (EP)
Inventor: BARTLETT JOHN REGINALD
IPC: B29C53/48
Filed: 1978-07-19
Abstract: A method of seaming together the edges of plastics sheet (10) by bringing them towards each other, leaving a small gap, and introducing a plastics strip (26) into the groove thus formed. The strip can be directly extruded into the groove so that it welds directly to the sheet edges. Alternatively, external heat may be applied, for example by a hot air jet just before the strip enters the groove, so that the strip welds to the sheet edges. The sheet, and possibly also the strip may comprise foamed plastics material. The seam thus formed can be rolled before the material has cooled so as to produce a flush joint. 
     This method can be used to produce tubular plastics bodies, for making into containers. Also disclosed is a method of fitting a metal end closure in which an outward flange on the closure is turned around the outside of the foamed plastics body and engages under an outward shoulder atthe rim ofthe body forming a circumferential seam, the material ofthe body being compressed between the flange and an upstanding annular wall of the end closure. An alternative method of producing a flush seam between plastics sheets comprises reducing the thickness of the edge portions of the sheets and then overlapping these portions and sealing them together. The reduced thickness areas preferably have complementary profiles.

Abstract: Apparatus for maintaining the velocity of a fluid constant, and in particular for maintaining an aspirator air velocity constant under varying atmospheric conditions. A precisely controlled air velocity is provided by a reference air source (134) whose frequency is derived from a crystal oscillator (136). The total air pressure from the aspirator tunnel (92) is compared with the total air pressure from the reference air source (134) using a matched thermistor pair (144, 146) to convert the pressure difference into an electrical error signal which is used to control the main air source (120) for the aspirator tunnel (92) such that the error signal is maintained at zero, thereby maintaining the air velocity in the aspirator tunnel (92) constant.

Abstract: A tabletting machine having a ring-shaped die table (25, 33, 27) rotatable about a generally upwardly extending axis (11) and having dies (40) arranged in bores in a die surface (38). Radially outer punches (16 - Fig. 7), supported in the die table (25) and reciprocably driven by a cam track (52 - Fig. 7) with respect to the dies (40), co-operate with radially inner punches (83) semi-rigidly mounted on a rotatable hub (23) to form and eject tablets from the dies. The hub (23) is rotated about an axis (10), parallel to the die table axis (11), and moves the radially inner punches (83) in a circular path to enter and exit the dies (40) in a predetermined sequence. A feed plate (102, 144, 146, 147), onto which tabletting material is supplied, directs the material onto distribution vanes (108) and thence into the dies (40). Individual pump means (50, 46 - Fig. 7) associated with the radially outer punches (16) and means (154, 155) for catching and extracting loose tabletting material failing from the dies serve to reduce contamination of the moving parts of the machine by the tabletting material.
