Patent DE-4219306-A1 (DE)
Inventor: THOLANDER LARS HELGE GOTTFRID
IPC: B65H51/22
Filed: 1992-06-12
Abstract: The invention concerns a method for feeding weft yarn to a loom, each weft yarn being unwound overhead from a spool on a yarn-feed device, within a single stroke of the loom as a function of the operation of a yarn-retention element. The weft yarn is force-fed using the yarn-retention element which is driven to rotate and acts continuously upstream of the yarn take-off point. The yarn-retention element is accelerated and decelerated in accordance with a speed-time curve which determines the rate of feed of yarn to the loom. The invention also concerns a weft yarn feed device in which the yarn-retention element (R) is of lightweight design and is coupled to the rotary drive (A) in such a way that it cannot move radially with respect to the spool axis (11) and so that it continuously crosses the rotational trajectory (U) of the yarn take-off point upstream of the weft yarn (Y) in the direction of rotation (2') of the take-off point, the rotary drive (A) being connected to a control device (8) which produces a speed-time curve (I) which determines the rate of feed to the loom (W).

Abstract: The end (2) of the concertina shaped, elastomeric tubular roll (1) is clamped by a tension ring (4) so that the concertina wall protrudes out of the tensioning point towards the base of the fixture (3) to which the ends of the tubular roll are fixed. The concertina wall then encircles the tension ring (4), turning 180 deg. The fixture end facing the concertina has a part (5) of constricted dia. bordered by a protruding flange (7) matching the main dia. of the fixture. The constricted part contains a ridge (6) round. The tension ring ID is less than the OD of the flange. USE/ADVANTAGE - The air spring has a ridgeless concertina shaped tubular roll, reducing its unreliability as a result of it stretching when pressureless.

Title: Paper web coating back application - uses gap between two rollers to apply layer to one side of glue impregnated paper web
Inventor: SCHOEN HORST
IPC: D21H23/56
Filed: 1992-07-27
Abstract: To produce a paper web with a coated back layer, for pressure sensitive carbonless copy paper, the paper web (1) is glued to give a full mass glue. The coating back layer (4') is spread over the paper web (1) between two rollers (2,2'). A rotating spreader rod (3') with a profiled surface, at one roller applies a vol. dosage of coating material (4) to the roller surface, for transfer to the web (1) as a coating back layer (4'). A further spreader rod (3), with a surface profile, rotates through a drive to give a vol. dosage of a watery preparation (5) to the other side of the web (1). Pref., the gap between the rollers (2,2') is set so that it is not smaller than the uncoated web thickness. The coating for the coating back has a solids content of 15-45 wt%. The watery preparation is a starch solution or a coating front material. The opposite side of the web to the coating side is polished before coating. USE/ADVANTAGE - The technique is for mfg. carbonless copy paper, where the image is transferred by pressure through ink-filled microcapsules. An even layer structure is formed at the web, even with high speeds, using a coating with different solid contents and viscosities without space holders. The system can be incorporated in a papermaking machine, together with a coating on the other side of the web to be dried together.

Inventor: DANTLGRABER JOERG
IPC: G05D16/20
Filed: 1992-08-13
Abstract: An hydraulic pressure control system for high press-stop drive cycles, and for the closure system of an injection moulding machine or press in particular, has a piston whose active dia. is pressurised by an hydraulic flow medium under the pressure of a pump and through a control valve. The pump which pressurises the acting piston is an electronically regulated type; it has a regulating device whereby the pressure on the acting piston is determined by controlled/regulated return of the pump pressure, when relieving the pressure in the chamber. The figure shows an example, for controlling hydraulic pressure in the mould closure area of an injection moulding machine. The features include those referred to in the claim e.g. the pump (148) which loads the pressure transmitting piston (128), the controller (190), the pressure chamber (126) and the operating piston (112). ADVANTAGE - The system enables pressure release shocks to be avoided. It does so whilst also ensuring short cycle times. It has a simple construction.

Title: Sheet sepn. and orientation feeder for single-sheet printer - has independently rotated suction rollers at sides of machine for sheet alignment with linear imaging array
Inventor: FLADE GREGOR
IPC: B65H9/20
Filed: 1992-11-26
Abstract: The feeder takes sheets one by one from a stack by vertically and horizontally running suction belts which transfer them to suction rollers comprising several discs (3). The rollers on opposite sides of the machine are driven independently and at different speeds under the control of electrical pulses from intermediate rows of CCD imaging cells (18-20) on a fixture whose shape corresponds to that of the rollers. This ensures that the leading edge of each sheet is aligned with a row of cells. ADVANTAGE - Each sheet is oriented after sepn. without recourse to abutments for its leading edge and sides or to sheet stopper.

Title: Facsimile apparatus with information reporting - stores user codes and potential caller telephone numbers and sends caller number information back to user
Inventor: SEO SEOK-HWAN
IPC: H04N1/32
Filed: 1992-11-27
Abstract: The apparatus can report information about a caller at the receiver to a given user. User codes and the telephone numbers of potential callers are input and stored in the apparatus. When the facsimile receives data a detector determines the telephone number of the caller. The receiver determines whether the above-determined number corresponds to one of the stored numbers of potential callers. A predetermined data report is transmitted to the user according to the telephone number of the caller when the number matches a stored number. The data is reported via a loud speaker, the user's telephone or the user's computer terminal. ADVANTAGE - information about caller can be reported to user situated away from fax machine.

Title: Pneumatic yarn splicer - has scissor motions to trim loose ends to avoid thick places in yarn
IPC: B65H69/06
Filed: 1992-12-03
Abstract: In a process to splice a textile yarn pneumatically, the yarn is laid in the splicer with exposed ends, which are untwisted and arranged with fibres parallel. These are then drawn back in to the splicer chamber to be pneumatically spliced, and then released. The process is accompanied by extra trimming cuts at each stage. The appts. is also claimed. The splicer is constructed to work automatically when the two ends of yarn are laid opposite to each other in the splicing chamber (41). Each end is held, and there are scissor motions which cut the yarn in specified places at the appropriate time. ADVANTAGE - The splice is accomplished without the loose ends being wrapped in to form a thick place in the yarn.
