Patent DE-19504517-C1 (DE)
Inventor: KOPP LORENZ
IPC: C25D17/06
Filed: 1995-02-11
Granted: 1996-08-08
Abstract: The invention concerns a method and device for galvanizing plate-shaped products (4), in particular printed boards, in horizontal continuous plants through which the products pass in any order. Circulating contacting means are used to connect a bath current source electrically via slide rails to the product to be treated. Sensors detect the beginning and end of each individual product when it enters the galvanizing plant and determine the conveying speed of the product. The sensors (24) deliver sensor signals to a control system which establishes whether or not the contacting means find a product to be treated at the gripping point. The contacting means are connected to the bath current source electrically and with low impedance, in the galvanic sense, only when a product to be treated is in the contact region of the contacting means.

Filed: 1995-06-01
Granted: 1996-12-19
Abstract: The pivoting door or window comprises a fixed frame (10) and a hinged section with a mechanism which acts between the frame and the hinged section. The mechanism is constituted by movable locking pins (25) which are mounted on an activating rod located along bars (11 -14) forming the hinged section or frame. The mechanism also has stationary fastening parts (15) which are fixed in frame or hinged section bars. The activating rod can be displaced by means of a handle (30) by which the locking pins can be led (45) into two operating positions relative to the associated fasteners. One position (25) characterising the closed position and the other position (25') the pivoting position of the hinged section. Two horizontal and two vertical bars are connected in pairs to form the hinged section. After their connection they form two corners (31,33) located at the side of strap hinges and two corners (32,34) located on the opening side of the frame and the hinged section. The window fasteners are mounted at identical distances in the uprights and horizontal bars forming the frame or hinged section.

Title: Portable drilling rig with manual and automatic reversing switches
Inventor: SCHEID WINFRIED
IPC: E21B3/025
Filed: 1995-08-22
Granted: 1996-11-28
Abstract: A drilling apparatus, the drill head (16) of which can be connected either to a drill (10) or a casing string (28), is also fitted with an automatic direction reversing mechanism (64) which is designed so that the driven part (14) of the drill head executes backward and forward movements of less than 90{, but preferably 20{ to 30{. In this way the drill head can also strike the casing string when sinking it. Activation of the first direction change-over switch (60) corresponds to the normal drilling mode in which the operators control the drill under manual directional control. The second direction change-over switch (62) is activated when earth is ejected by the twist drill. The drill is accelerated to full speed and the earth is ejected by the rapid reversal of direction. Activating the third direction change-over switch (64) causes the hydraulic motor (26) to be set in motion for only short time intervals in clockwise and anticlockwise directions.

Title: Method for operatively treating difficult-to-remove duodenal ulcers
Inventor: SERGEEV IVAN V
IPC: A61B17/00
Filed: 1993-02-08
Granted: 1997-07-27
Abstract: FIELD: medicine; surgery. SUBSTANCE: in order to prevent incompetence of duodenal stump after Roux stomach resection, to treat complicated duodenal ulcer and also in case of chronic duodenal ileus, proposed method recommends to practise suprapyloric stomach resection, followed by formation of terminoterminal pylorojejuanastomosis with help of mobilized Roux segment. Same segment is also used for applying terminolateral gastrojejunanastomosis, but latter is positioned more distally in relation to pyporojejunanastomosis. Continuity of small intestine is restored by using enteroenterostomy practised at distance 30 cm from gastroenteroanastomosis. Excessive pressure in duodenum is eliminated by organizing its retrograde drainage. Latter fact is important for prophylaxis of afferent loop syndrome. Suprapyloric resection makes it possible to use tissues unaffected by inflammatory process for decompressive pylorojejunanastomosis. Stomach resection lower boundary is passed some 1-2 cm orally in relation to pylorus. EFFECT: proposed method was used to operate 4 patients with good proximate and remote results. 3 dwg
