Title: Eversion of animal pelts during processing - by withdrawing from over a shaped tube attached to a suction line
Inventor: KARASCHINSKI WILFRIED
IPC: C14B15/00
Filed: 1978-11-08
Abstract: A process for turning a pelt which is still in tubular form, comprises drawing it over a tube which matches the shape of the pelt, and which is connected to a vacuum-line by means of a mechanical, electrical, electro-mechanical or pneumatic valve. The tube is interchangeable with others of different form to suit different pelts. The pelt is drawn from the tail end on to the shaped tube for 30-70% of its length. Whilst maintaining a firm grasp on the tail end, the suction valve is opened, causing the head end of the pelt to be sucked inside out into the tube. The pelt can be turned rapidly and reliably, in half the time, or less, required by previous procedures, and at the same time loose hairs and foreign matter is removed by the suction.

Title: Welded pipe fitting - produced by upsetting pipe ends for flange allowing access for weld inspection
Inventor: WONSAK GUENTER DR ING
IPC: B23P15/00
Filed: 1979-06-16
Abstract: A steel pipe fitting for welding pipe ends to pressurised vessels for very strict safety regulations, e.g. to a large-bore gate valve housing in nuclear reactor systems, is prepd. by applying heat to a pipe end all around the area for the intended weld. Axial upsetting produces an annular bulge which is then formed by external grooved rolls and internal back-up rolls to a dia. of the desired height. The dia. must be adequate to allow the final weld to be inspected during later routine checks by an ultrasonic transducer or an X-ray test head. This is a simple method of making such critical welded seams accessible for routine safety inspection where extremely strict safety regulations apply.

Patent DE-2936938-A1 (DE)
Inventor: ZEITRAEG ROLF DIPL PHYS
IPC: H04J3/06
Filed: 1979-09-12
Abstract: A pulse coded time division multiplex (PCM) telecommunication system has two non-synchronous clock pulse trains for controlling information transfer and switching operations, respectively. In a circuit arrangement for compensating phase differences resulting from deviations between both clock pulse trains there is arranged an intermediate store for externally controlled buffering of PCM words for half of a pulse frame and connected thereto a buffer store for internally controlled buffering of PCM words for a full pulse frame. The intermediate store is designed for two modes of operation under control of the external clock pulse train. In an active mode during one cycle at first a stored PCM word is read out and is then replaced by a new PCM word. In the second mode the same PCM word first is temporarily buffered and immediately read out thereafter. Change of operation is controlled by a control unit monitoring addresses for alternate read operations and write operations of the buffer store of a minimum off-set of selected addresses to obtain by skipping of half of a pulse frame sufficient off-set without continuous uncontrolled slippage losses.
