Title: Process and device for the drying of running yarn sets
Inventor: VOSWINCKEL GERHARD DIPL ING
IPC: F26B13/00
Filed: 1981-09-29
Abstract: The running yarn sets (2, 3, 4) are brought into contact with preheated air in a channel (11). The air is guided transversely through the yarn sets (2, 3, 4) from one side in a plurality of flow strips, conveyed on the opposite side of the yarn sets (2, 3, 4) into a channel portion (22) widened according to the total air quantity, deflected there and guided once again through the yarn sets (2, 3, 4), and conveyed into a further channel portion (30) located on the blow-in side. The procedure continues over one or more subsequent channel portions (31, 32, 33), until, after the air has passed through the yarn sets (2, 3, 4) a plurality of times in wave form, the blow-out of the air now laden with moisture takes place. Air-deflecting surfaces (24, 25, 26, 27, 28) inserted into the channel (11) are used for air guidance. The aim is to achieve a careful effective drying in a compact device. <IMAGE>

Patent DE-3145354-A1 (DE)
Title: Process for demoulding containers of thermoplastic sheet and apparatus for carrying out the process
Inventor: KIEFER GUENTHER
IPC: B29C51/44
Filed: 1981-11-14
Abstract: The invention relates to a process for demoulding deep-drawn containers of thermoplastic sheet. In this case, the containers are moulded in a moulding station, punched out and demoulded. The latter is carried out by a relative displacement taking place between mould bottom and side wall of the mould. If the container has undercuts, there is the risk of the container being displaced on the mould bottom or falling off during demoulding. This is intended to be avoided by the invention. This is achieved by using a vacuum to suck the container bottom against the mould bottom during demoulding, at least until the undercuts are demoulded.

Patent DE-3204668-A1 (DE)
Title: Method and apparatus for the production of belt pulleys
Inventor: DORAKOVSKI VANCO
IPC: B21D53/26
Filed: 1982-02-10
Abstract: The invention proposes a method and an apparatus by means of which belt pulleys are manufactured from a blank inserted between the head stock and the tail stock. While a constant pressure is maintained between the head stock and the tail stock, the head stock is made to rotate and the belt pulley blank is formed into a belt pulley by pressing on the side walls of the blank. If a belt pulley with a plurality of grooves is to be created, this deformation is brought about by the combination of at least two external rotating rollers (1110, 1100) and at least one internal rotating roller (250), the latter deforming the blank, while it is positioned within the inner circumference of the blank and used on an inner-roller shaft rotatable in the drive shaft. If a belt pulley with only one groove is to be created, the outer roller can deform the blank. The method of internal deflection during the production process increases the quality and quantity of the belt pulleys produced by means of the apparatus and method according to the invention. The invention furthermore provides an automatic alignment device, an automatic blank feed device and an automatic delivery device in order to move the blank into the appropriate position between the head stock and the tail stock and remove the finished product from the arrangement. The overall installation and the related method provides a system for the automatic production of belt pulleys. <IMAGE>

Patent DE-3216429-A1 (DE)
Title: Method for handling the cashless clearing traffic without documents
Inventor: EICHEL DIETRICH
IPC: G06Q20/00
Filed: 1982-05-03
Abstract: The method makes it possible to generate, by manual data acquisition (for example by the client via videotex or a self-service terminal) or by automated document reading (for example at the first financial institution commissioned) of only a few numeric information items, undocumented data records which, due to the beneficial redundancy of the data (in matters of information theory) make it possible, with the reliability which is absolutely necessary in payment transactions, to supplement them by the name of the client in the computer centre of the first financial institution commissioned. After undocumented forwarding to the financial institution managing the account of the receiver of the payment, they are assembled in the computer centre there to form a complete undocumented remittance by being completed by the name of the receiver of the payment, due to the beneficial redundancy which exists. The redundancy is introduced by numeric individualisation of each payment process at the client and receiving end by issuing corresponding remittance order numbers to the (future) client and corresponding remittance slip numbers to the (future) payment receiver by the financial institution in each case managing the account. By strictly binding the remittance order and remittance slip numbers to the     - bank code of a particular financial institution, - account number of the client and payment receiver at this financial institution,   - identification of a particular payment process, it is ensured that the correct plain-text information is always set in the data record, and a visual account call check during the entering to the account of the client or, respectively, payment receiver is unnecessary. Moreover, the payment receiver only needs, in addition to the amount, the standardised abbreviated numeric information "remittance slip number" for identifying a payment process. The method utilises the fact that the financial institutions have reached a degree of automation in which the plain-text information for the client and, respectively, for the payment receiver are stored in the master file of the relevant institution managing the account.

Patent DE-3236806-A1 (DE)
Title: Disposal element for stoma patients
Inventor: RICHTER KURT
IPC: A61F5/445
Filed: 1982-10-05
Abstract: The element described at the outset, which is intended to be used for controlled disposal in stoma patients, lies compactly and unobtrusively at the abdominal wall level, and in terms of inventiveness is very significantly superior to the present state of the art in this field. The element is shown assembled, in part semi-diagrammatically, in the following drawing (Fig. 13). It consists of the screw (Fig. 1), the closure lid (Fig. 2), the intermediate ring (Fig. 5), the closure element (Fig. 7), the magnetic ring to be implanted (Fig. 9) and the closure element covering (Fig. 12). Since the invention is sufficiently characterised as such by means of the enclosed descriptions of the invention, the drawings and the cited patent claims, it is possible to dispense with further, numerical details in the drawings. It is recommended to produce three different sizes of the said disposal element, which must be considered necessary due to the very fact that the stomata will, for whatever reasons, be of different sizes. The distinctive feature of the invention is that, with the exception of the closure element covering intended for one-off use, all the other components are intended and suitable for long-term use, and as a result a cost-saving effect in terms of economy can be achieved. <IMAGE>

Title: Method for controlling an electromechanic program switching mechanism and program control for carrying out the method
Inventor: STEUDEL GOETZ DIPL ING
IPC: G05B19/048
Filed: 1983-02-25
Abstract: A program control exhibits an electromechanic program switching mechanism 1 which exhibits a number of switch positions corresponding to the programs to be processed. To make it possible in this arrangement to detect errors which have occurred in the program sequence or operating errors, the program switching mechanism 1 is set into a predetermined switch position in the error case and is electrically locked in this position. This predetermined switch position is skipped in the case of fault-free program sequence. The program switching mechanism 1 therefore exhibits, in addition to the switch positions required for normal program sequence, at least one additional switch position 20, 21. <IMAGE>
