Abstract: Device and method for controlled supply of a bonding wire, in particular gold bonding wire (10), to the wedge or to the capillary (22) of a bonding head (21) which can be moved up and down (double arrow 30). The device is characterised by a bonding-wire guide duct (12, 18, 19, 20) which is arranged upstream of the bonding capillary (22) and into which a fluid connection (15) opens, which can be connected alternatively to a compressed-gas, in particular compressed-air (13), or subatmospheric-pressure source (14), and by a bonding wire slip-clamp (23) which is assigned to the bonding-wire guide duct (12, 18, 19, 20) and in particular arranged in front of or at the capillary-side end of the same and which is active, or closed, permanently or only during lowering of the bonding head (21) for touch-down. Furthermore, a stationary bonding-wire clamp (24) is preferably arranged downstream of the bonding-wire guide duct (12, 18, 19, 20), which clamp can be closed or opened depending upon the height of the bonding head (21), with retraction and corresponding removal of a bonding-wire section hanging downwards out of the capillary tip (26) immediately before the second touch-down. <IMAGE>

Title: Method and device for packaging of bags
Inventor: MUELLER WERNER
IPC: B65B5/10
Filed: 1989-03-02
Abstract: In a method for packaging of bags, with a flexible filling which can move inside the bags, the bags are deposited one after the other in pairs, with their thick ends pointing outwards and with their thin ends overlapping one another, on a formation surface which is inclined in the direction of forward travel and which can be driven in a stepped manner. The formation made up of several pairs of bags is taken up and introduced from above, in layers, into a packaging container. In this way it is ensured that, in the case of high packaging rates, the pack volume of the packaging containers is optimally utilised and an undesired shifting of the bags within the formations and the packaging container is avoided.

Inventor: MAHMUD SHABAZ
IPC: H04N9/64
Filed: 1989-08-12
Abstract: 2.1. To achieve effects in the processing of video images, it has previously been customary to work with frame buffers or produce the changes in the image by means of software. These methods are very complex and can therefore only be used in the field of professional electronics. It is therefore the object of the invention to specify a device by means of which video effects are achieved in a simple manner. 2.2. This object is achieved by the fact that during the processing of the colour signal in a video device with digital signal processing, a manipulation logic is inserted into the signal path, by means of which single or several bits of a data word, which specifies the colour content of a picture element, are selectively changed. 2.3.
