Title: Turn-in apparatus for a machine for producing book covers
Inventor: KAMPEN JAN-DIETER
IPC: B42C15/00
Filed: 1988-05-27
Abstract: In a turn-in apparatus for a machine for producing book covers, turn-in systems are used for turning in the front edge and turning in the rear edge, each consisting of a turn-in strip (13; 13') which extends transversely to the direction of passage, is tiltably mounted, is controlled as a function of travel and, together with an assigned supporting strip (14; 14'), forms a clamping tool. In this arrangement, the turn-in strips (13; 13') are so controlled that, in order to raise the cover material (1a), they move along upwards, respectively, the front and back lateral surface of the cover boards (1b) and, after supporting of the cover unit (1) by the supporting strips (14; 14'), they move counter to the direction of passage in order to turn over the cover material (1a) and press it onto the cover board (1b) for the turning-in of the front edge, or in the direction of passage for the turning-in of the rear edge, at a speed which is higher than the running speed of the cover unit (1), and the cover unit (1) is held clamped between the turn-in strip (13; 13') and the supporting strip (14; 14'). Moreover, depressor members (46; 47) are provided which act from above on the region of the cover unit (1) near to the front edge and to the rear edge. <IMAGE>

IPC: B21B43/06
Filed: 1988-05-30
Abstract: The invention relates to a working method for the prevention of deformations of rolled sections, especially asymmetrical sections, during the cooling process between deposition on the rake-type cooling bed and the cold shear or straightening machine. In order to provide a working method and an associated apparatus by means of which deformation of the sections during the cooling process is reliably prevented, at least in the region of the ends to be introduced into the straightening machine or cold shear after cooling on the rake-type cooling bed, and which can be employed particularly in the case of sections straightened in multiple strands, it is proposed that the sections (15) be prevented during the entire cooling process from deforming due to cooling, at least at the ends to be introduced into the cold shear or straightening machine (48), by the action of external forces until just before the cold shear or straightening machine (48). <IMAGE>

Inventor: ANDRASCEK ERNST
IPC: G03F7/42
Filed: 1988-06-23
Abstract: The invention relates to a stripper solution for cured positive photoresists and to a process for the use thereof. The solution contains     a) 20 to 80 per cent by volume of a lower water-soluble alcohol, b) 10 to 50 per cent by volume of one or more glycols or glycol ethers and c) deionised water in such a proportion that the total of the proportions a), b) and c) gives 100 per cent by volume,  and also d) an addition of a basic alkali-free component or an acidic component in a proportion of 1 to 4 parts per thousand.   In a bath filled with this stripper solution, even stressed positive photoresist layers can be detached, for example from semiconductor substrates, with ultrasonic assistance without problems and free of residue. Aluminium layers or polyimide layers located below the photoresist layer remain intact, and also there is no contamination.

Patent DE-3824048-A1 (DE)
Inventor: BEYER ECKHARD DR ING
IPC: B23K26/00
Filed: 1988-07-15
Abstract: In a process for machining workpieces using a laser beam, optical and/or acoustic signals generated in a machining region are recorded and used to obtain actual values which are compared with corresponding reference values of a processing diagram specific to the material and to the machining. The results of the comparison are used to control the machining process by influencing it in a predetermined manner. In order to influence the machining region with a process gas in an appropriate and cost-effective manner, process gas is supplied to the monitored machining region in which the optical and/or acoustic signals are recorded, and the type of process gas and/or at least one gas supply parameter are continuously adjusted.

Patent DE-3841307-A1 (DE)
Title: Vehicle hydraulic brake system
Inventor: FRIEDOW MICHAEL
IPC: B60T8/44
Filed: 1988-12-08
Abstract: The invention relates to a vehicle brake system with at least one brake pressure modulator for limiting the slip which might occur between at least one vehicle wheel and a carriageway on which the vehicle in question moves. In a known vehicle brake system a brake pressure modulator is assigned to each vehicle brake, which modulator must be capable of essentially fully reducing the highest possible brake pressure emanating from a brake master cylinder. Such brake pressure modulators must be very efficient. They are accordingly expensive and heavy. The invention therefore proposes to insert brake pressure modulators (26, 26a) of cheaper and lighter design and with reduced efficiency between the brake master cylinder (18) and the wheel brakes (3, 4, 7, 8) and to assign an actuator (21, 25) to the brake master cylinder (18), which actuator, for example, comprises a brake booster, already provided, and a valve arrangement (25), which controls the booster so as to reduce the brake pressure in the brake master cylinder (18) as necessary. <IMAGE>

IPC: F16H61/08
Filed: 1989-02-28
Abstract: The invention relates to a hydraulic control device for an automatic transmission. According to the invention, a non-return valve (9) and an opening (7) in an oil supply passage (b) to a collector (10) are provided, so that the influence of oil flowing out of the collector (10) is eliminated when a hydraulic servo device (C1) is relieved of pressure. The hydraulic pressure is supplied to the servo device (C1) via an opening (6) and to the collector (10) via the oil supply passage (b), which is separated from the oil passage (a) to the servo device (C1), the non-return valve (9) being open. In the event of pressure relief, the hydraulic pressure in the hydraulic servo device (C1) is quickly relieved, but the hydraulic pressure in the collector (10) is only gradually relieved (through opening 7) as a result of the non-return valve (9) which is now closed. <IMAGE>
