Title: Slubbing guide channel having number of applications - keeps slubbing at constant mean density on feed into spinner through structure of entry and outlet points
Inventor: REISING REINER
IPC: D01H5/38
Filed: 1990-08-02
Abstract: The guide channel, to carry the slubbing from its can to the slubbing feed of a spinning appts., has an outlet opening offset from the entry opening. Their shape and positioning ensures that the slubbing runs out of the channel at the same mean specific density independently of the changing take-off position within the can, and between the can and the entry opening, and without any drafting or compression to keep it always at the same outlet point of the channel. The surface of the channel in contact with the slubbing is polished and/or coated so that the slubbing has no friction or other mechanical effects acting on it above permissable levels. The sensor of a slubbing monitor is at the outlet point of the channel. The outlet opening is a gutter with two side walls flanking the base and with rounded edges for the slubbing to pass over the base. The channel can have side walls running straight from the entry opening to the outlet opening and the outlet point, so that the cross section tapers towards the outlet point. ADVANTAGE - The slubbing guide channel can have a number of applications, such as to settle the slubbing or provide a slubbing monitor, without any adverse effect of the slubbing material.

Title: Sound- and heat-insulated bus roof - has polyurethane foam perforated before compression to form inner ceiling
Inventor: HERZ RICHARD DR
IPC: F16L59/02
Filed: 1991-07-17
Abstract: A vehicle roof, partic. of a bus, is sound- and heat-insulated, using an inner ceiling of polyurethane foam.
