Abstract: The invertable confectionery mould (1) provided with a plurality of mould cavities (2) is shown in the inverted or confectionery item ejecting position, in Fig. 4. The base of each cavity (2) is penetrated by a passage 4 closable by an annular seal (22) around the head of a plunger (7). A head (64) of a seal housing (56) is used to depress the plunger (7) mechanically to the open position shown whereby compressed air can flow along a hose (61), a central bore (59), a laterally-extending slot (60), holes (28) in a disc (27), and the passage (4) to enter the cavity (2). The introduction of the air assists the mechanical force applied to the plunger. Use of the compressed air to assist mechanical ejection of the confectionery item is not essential but is preferred. Alternatively, by cutting back the heads (64), the plungers (7) can be opened by air pressure alone. The annular seal (18) may alternatively be effected Fig. 1, on the face of the mould cavity (31). <IMAGE>

Title: Warp sheet input and terminal thread high speed attachment - by using sizing installation for continuous changeover of warp following or changing type, with short runs, avoiding wastage
Inventor: GROTH WOLFGANG
IPC: D02H5/02
Filed: 1991-05-17
Abstract: Yarn sheet advances around the roller and is distributed over a series of rollers into the jointing unit. When the beam collection is coming to an end, the yarn is held in the unit and lifted by a separator. The rod held on the assembly, pushes the yarn distributed from the sheet assembled around the roller from the beam collection, forward into the jointing unit and lying alongside the yarn. The two are pressed together with a bonding material. The trailing ends of the yarn are cut away, and the yarn from the collection of beams, which may be a different style to the yarn, can travel forward through the installation. Jointing takes only a few minutes, and the compensating rollers convey the yarn through the size vat pre-dryer dryer and to the end beam without wastage. ADVANTAGE - Avoids wasted ends due to warp not passing through the chemical process in pref. time, by having to stop for long periods to join up.
