Patent DE-4134994-A1 (DE)
Title: Yarn folding frame - has a service robot to ensure continuity by automatic means
Inventor: MIMA HIROSHIMA
IPC: D01H9/00
Filed: 1991-10-23
Abstract: A two-for-one yarn folding frame with a service robot, producing twisted thread from two stacked reels. The robot travels along the frame, and in accordance with requirements changes the reels of yarn or thread, locates yarn ends, threads up, indicates broken ends and replace and thread up any one of the two supply reels. Pref. on the yarn folding frame (1) the winding creel fills the thread reel (7) and a sensor actuates a warning when the reel is full, so that the service robot (20) may commence a thread reel changeover. The full reel is passed to the conveyor (17) and an empty tube (4) is brought down from the reserve, and which is refilled automatically. To find the thread end (Y) a suction tube and roller is actuated by the robot, between the drive roller (6) and tube (4). The warning lamp is actuated when a broken end is sensed. The robot ensures the reel (7) will accept more thread, and begins a process to changeover the supply reels, or ensure the two yarns are available at the twist point. To change the supply reels, an arm (25) in the robot has a top grip which lift both reels (2a,2b) off the spindle (3). At the same time an airpressure jet on the end of the arm blows away dust and fluff from the spindle base. New yarn supply reels are lifted from a conveyor (16) at the front of the frame, and into position on the spindle (3). To bring ends of yarn through from the supply reels (2a,2b) a top arm is provided with a suction device, which can be held in position by a pneumatic cylinder, onto the top tubular adaptor for the reels. A sensor in the arm detects when the two yarns are present, and these are held in a clamp. ADVANTAGE - Changes the yarn supply reels in an efficient manner, avoiding loss of yarn.

Title: Vehicle fuel-injected IC engine design
Inventor: HELD VEIT DR ING
IPC: F02D37/02
Filed: 1993-02-03
Abstract: An IC engine with fuel injection uses an extremely lean mixture and has exhaust gas recirculation (EGR).

Patent DE-4317154-A1 (DE)
Title: Circuit for driving a switching transistor
Inventor: ELGERT ACHIM
IPC: H02M3/335
Filed: 1993-05-24
Abstract: It is known for the drive of a power switching transistor to be implemented by means of a driver transformer (isolating transformer). This isolating transformer is disadvantageous since, on the one hand, it must always be operated in saturation and, on the other hand, care must be taken in circuitry terms that the power switching transistor is not switched on when the supply voltage breaks down. The object is to create a circuit for driving a power switching transistor, which circuit is as cost-effective and efficient, in terms of power, as possible. This object is achieved in that the driver transformer is operated in the forwards mode with the windings having the same polarity, and a capacitor (C2) is arranged in series with the primary winding (Lp) of the driver transformer. <IMAGE>
