Title: Methods for manufacturing mineral-wool mats or slaps and equipment for carrying them out
Inventor: LIEBERT HORST
IPC: D04H1/645
Filed: 1980-10-15
Granted: 1984-05-24
Abstract: In the manufacture of mineral-wool mats or slabs, the raw materials are melted in a melting furnace and are spun to fibers in a spinner. The fibers, after admixture of a resin binder, are deposited so as to be formed to wool mats in a collecting chamber, then cured, trimmed at the sides and cut up into lengths. Both during spinning and during trimming, cutting up into lengths and a subsequent final inspection and check for defects, waste products arise. In order not to have to deliver these waste products, as hitherto, to a proper dump but, instead, to be able to recycle them direct to the production process, the waste products are broken up into smaller pieces and/or unravelled, heated and then briquetted while hot, whereupon the briquettes, possibly after cooling down and interim storage, are combined with the raw materials which are to be melted and thus returned via the melting furnace into the production process.

Title: Process for the treatment of the bottom product of extractive-distillation processes for obtaining pure hydrocarbons
Inventor: PREUSSER GERHARD DR DIPL CHEM
IPC: C07C1/00
Filed: 1981-07-23
Granted: 1984-01-05
Abstract: A method for working up residues of an extractive distilling process for obtaining pure hydrocarbons. The residue from an extractive distilling column is fed to the about middle part of a distilling column. The hydrocarbons are distilled and removed at the head of the distilling column and the solvent is removed at the bottom of the distilling column. A sidestream is removed from the distilling column at a position above the feed plate for the residue from the extractive distilling column via a so-called reflux evaporator plate having an elevated level of liquid. The sidestream is heated by indirect heat exchange with the solvent flowing from the distilling column. The heated-up sidestream is fed back into the distilling column at a level at or above the reflux evaporator plate. The concentration of the solvent at the reflux evaporator plate is controlled by the amount of reflux at the head of the distilling column. The heating of the side stream reduces the heat requirement of the bottom boiler of the distilling column by about 35 percent.

Title: Bobbin run-out detector, and a bobbin changing mechanism incorporating the detector
Inventor: KOSMAS NIKOLAOS
IPC: D05B59/00
Filed: 1984-02-21
Granted: 1987-12-23
Abstract: A bobbin run-out detector for a lockstitch sewing machine is responsive to thread tension for sensing when the bobbin is empty of thread. The thread tension is sensed by a hook member (168; 332) engageabie with the thread extending from the bobbin, the hook member (168; 332) being moved by a resilient bias as a result of loss of thread tension consequent on emptying of the bobbin. The hook member (168, 332) is linked to a shutter (174; 334) which moves with the hook member (168; 332) in order to influence a light beam, light receiving means (202) being responsive to such influence to produce a signal indicative of bobbin run-out. The signal may stop the machine and/or actuate an alarm. Alternatively, the signal may actuate a bobbin change device (2, 4, 14, 16) for removing the empty bobbin and for inserting a previously wound bobbin, to permit sewing to resume.
