Patent DE-4037778-A1 (DE)
Title: Machine for dressing frame corner welds - has first moving carriage carrying transversely moving second carriages which has two stop rollers to enable cutter to act along weld beads
Inventor: STUERTZ KARL-HEINZ
IPC: B23C3/12
Filed: 1990-11-28
Abstract: Equipment for dressing weld beads at the corners of (partic.) plastic extruded frames such as those for windows etc. has a sliding carriage to hold a vertically moving cutter for the outer corners and to move the corners concerned in a plane parallel to the frame. The carriage has a transverse carriage which moves in a parallel plane to itself but at 90 deg.; at least one stop acts against this latter carriage, moves against the outside surface of the frame and guides that carriage parallel to the frame section. More specifically the corner weld joint between two different plastic sections is dressed by the equipment with main carriage sliding on rods and carrying its own rods at right angles, so that the second carriage can be moved accordingly. This second carriage holds a motor-driven cutter. The carriage also has two arms with end rollers to serve as stops. The arms are suitably hinged and moved accordingly. When the first carriage advances to the frame the roller stops the section; the second carriage then moves at 45 deg. and the corner is dressed off accordingly.       ADVANTAGE - The cutter (or side-milling cutter) retains its axial position. A corner made by welding together different profiles can be dressed without tilting and turning a carrier arm for the cutting tool. (Dwg.0/1)
Patent DE-4037848-A1 (DE)
Inventor: SCHULZE ECKEHART
IPC: B30B15/24
Filed: 1990-11-28
Abstract: In a hydraulically driven machine with two vertical differential cylinders as drive cylinders arranged at a mutual lateral distance on side cheeks of the machine frame, the control components are two follow-up control valves with an electrically controlled predetermined reference position for an upper tool and a mechanical actual position indication which have a locking basic setting and two alternative through-flow settings which are allocated to the fast and load forward action directed downwards on the workpiece and the return action directed away from the workpiece. A piston area of the drive cylinder pistons limit an upper drive pressure chamber and a smaller piston area limits a lower drive pressure chamber of the drive cylinders through which axially passes the piston rod concerned to which the upper tool is connected. In fast forward action the weight of the upper tool and the piston is used as the driving power, whereby the pressure medium flows into the upper drive pressure chamber via inlet valves. In load forward action high pressure is applied to the upper drive pressure chambers. On return action the pressure in the upper drive pressure chambers is relieved via pressure-controlled outlet valves.

Title: Automatic yarn repair - uses controlled blown air intensity to detach broken yarn end with adjusted settings to improve the success rate
Inventor: NICKOLAY HELMUT DIPL ING
IPC: D01H15/00
Filed: 1990-12-11
Abstract: To give an automatic broken yarn repair at a spinner, esp. a ring spinner, the broken yarn end is detached from the winding cops (3) by a stream of blown air (21) with an intensity which is controlled according to the deg. of success in loosening the yarn end from the conical wound section (22) of the cop (3). Pref. the blown air stream (21) control is set by the yarn repair procedure for individual cops (3). In the event of a failure to detach the loose broken yarn end, the air stream intensity is increased on the second attempt, and then returned to the initial intensity on a third attempt. The success rate of the blowing actions is formed from a number of yarn repair procedures and, if it fails to achieve a nominal success rate, then the air blowing intensity is increased for subsequent yarn repairs. ADVANTAGE - The system matches the action of the blown air stream to actual conditions.

Patent DE-4117032-A1 (DE)
Inventor: WILMS ELMAR DR
IPC: C11D3/22
Filed: 1991-05-24
Abstract: The aim of the invention is to make it possible to manufacture, by a simple process which involves minimum expense, a highly effective free-flowing, phospate-free foam-inhibitor preparation which can withstand being mixed with the usual powder-form components of washing or cleaning agents without the granular structure being destroyed and without producing dust, and will nevertheless dissolve rapidly, without leaving any residue, under the conditions of use. This is achieved by carrying out a granulation process in a granulator-mixer, 80-200 parts by weight of a carrier-salt mixture, containing alkali-metal sulphate and alkali-metal carbonate, being mixed intensively with up to 8 parts by weight of a cellulose ether mixture. Up to 16 parts by weight of water are added, followed by 5-30 parts by weight of a liquid organopolysiloxane, granulation being continued until completion of the process.

Title: Fibre tip pen and closure cap - has sintered or foamed stopper inside cap with capillary rate matched to that of fibre tip
Inventor: HOHEISEL KLAUS
IPC: B43K23/08
Filed: 1991-07-18
Abstract: Fibre tipped pen has a sealing cap with an internal stopper. When the cap is positioned on the pen the fibre tip touches the stopper which is mfd. in a foamed or sintered polymer e.g. polyethylene, polypropylene or PVDF. The stopper material has a capillary action similar to that of the fibre tip. Equal capillary effect in both tip and stopper material ensures that the tip does not dry out during long periods of storage esp. in different positions. Ideally both the tip and stopper are mfd. in the same material. ADVANTAGE - The pen is stored in different positions without causing smearing and can be obtd. by machinging to high tolerances. The fibre tip pen (1) has a sealing cap (2) with an internal stopper (4) which contacts the fibre tip (3) when the cap (2) is located on the pen body (1). The stopper (4) is mfd. in a porous material e.g. various foamed or sintered polyolefins or PVDF. Both stopper (4) and fibre tip (1) are mfd. to close tolerances and the tip (1) can have a variety of profiles according to use.
Patent DE-4129465-A1 (DE)
Inventor: SERGEL HORST DIPL ING
IPC: G01B21/06
Filed: 1991-09-05
Abstract: The invention relates to a method for measuring a length, in particular for determining an overlap length on a spooled/reeled material strip. In order to be able to detect the overlap length automatically, it is proposed that the front end of the material strip is detected on the drum by means of a detector and at the same time the associated angular position of the drum is measured, that after the material strip has been spooled/reeled, its rear end is indicated by the detector and simultaneously the angular position, assigned to the rear end, of the drum is measured, and that, finally, the length of the strip is determined in an evaluation unit from the difference value of the angular positions of the drum. <IMAGE>

Title: Welding process - by heating parts to be joined at welding seam and forging together with force using preset welding process parameters
IPC: B23K20/12
Filed: 1991-10-31
Abstract: Welding process and equipment, where the parts to be joined are heated by electric, mechanical or other energy at the welding seam and subsequently forged together with forging force (F) and where the welding process parameters are set so that the ratio of heating energy (Ew) to forging force (F) is constant and equals the product of a process-specific constant (A) and the upset shortening (d). The product of constant (A) and upset shortening (d) gives a process-specific quality factor (K) constant for a given process. The process parameters for heating energy (Ew) and forging force (F) for a required upset shortening (d) are computed and set up by means of quality factor (K). For welding with magnetically moved electric arc, the quality factor (H) is related to the ratio of applied electrical energy (EE) to forging force (F). For supervision of a welding process, the process parameters and upset shortening (d) are entered, the actual value for constant (A) is computed and compared with a reference value of (A) which represents the optimum process parameters for the required upset shortening (d). Process equipment is also claimed. USE/ADVANTAGE - Provides an improved means of determining, setting and monitoring welding process parameters, without or with only very few test welds.
