Title: Shredder for textiles esp. for pulling carpet rags - has chopped material fed by gravity to pinned cylinder rotating in pinned housing with free fibres drawn off separately in air stream
Inventor: GRADWOHL HEINER DIPL ING
IPC: D01G11/04
Filed: 1996-05-31
Abstract: A shredder for textiles is fed by gravity without any special feed devices. A rotating cylinder (1) is fitted with rows of pins which intermesh with pins fixed in the housing (5a,5b). Fibres and trash (non-fibre component and short fibres) are removed separately at different positions (8,12) of the machine. The cylinder and housing can be adjusted relative to each other. Pref. the pins are fitted to boards (2a,2b) attached to the cylinder (1) and housing (5a,5b). The cylinder is adjusted to run in a slightly eccentric position with increased intermeshing near the bottom. Chopped feed material is supplied by gravity through the feed inlet (3) and separated fibres are drawn off in an air stream by suction at an outlet (8) near the top. Heavier waste materials fall to a grid (11) and are removed at the bottom outlet (12). Provision is made for cooling the shredding region. Two or more machines can be placed in series with the bottom outlet of one machine connected to the inlet of the next one. An alternative design has two cylinders rotating side by side at different speeds to give a staged break-up which is advantageous for some materials.

Patent DE-19638619-A1 (DE)
Inventor: BRUCKMANN MANFRED
IPC: H03K17/687
Filed: 1996-09-20
Abstract: The invention concerns a device for reducing the short-circuit amplitude of a disconnectable, non-latching MOS-controlled power semiconductor (TL1) with a control unit presenting a driver stage (10) with two complementary transistors (T2, T3), a collector-emitter control (8) and a limiting circuit (6), that is placed between an input (12) and a reference potential ("-") of the driver stage (10). Said limiting circuit (6) is connected to an output (16) of the collector-emitter control (8) on the input side, which is interconnected with the collector connection (C) of the power semiconductor (TL1) on the input side by means of a decoupling diode (D1). The decoupling diode (D1) is connected by a resistance (R1) on the anode side with a positive terminal of a first control voltage source (UH1) of the driver stage. The invention foresees an additional transistor (T5) and a resistance (R5) . Said additional transistor (R5) and its collector-emitter section are connected electrically parallel to the base-emitter section of the switching transistor (T2) of the driver stage (10) and the resistance (R5) between the base and the emitter of said additional transistor (5). The control circuit resistance (RG) is bypassed by a diode. Thus, the known device for reducing a short-circuit amplitude of a disconnectable, non-latching, MOS-controlled power semiconductor (TL1) is improved in such a way, that its switching speed no longer changes.

The additional rollers are bending-compensating, working with flexible roller covering. Active supports are interconnected. Supports acting against flexibly-cased pressure rollers, induce plane extended nips. Additional pressure rollers have bending compensation rollers with radially moving covering. The nip (T) is held under control in a fixed spatial location during operation. The suction roller is hollow, with a core tube (32) around which the internally-supported covering (30) runs. The external suction box (34) extracts from its interior (36). A press felt (62) is carried by the additional rollers. To exchange felts (6, 15, 25, 62) an introduction tool is provided. Additional rollers are supported for this purpose by equipment fastened to the respective yoke. Through the nip (T) passes at least one endless dewatering felt, below and/or above the web (A). The nip is prolonged and has pressure application units.
