Patent DE-3926287-A1 (DE)
Title: Use of omega-conotoxin GVIA or its analogues - as pre-synaptic calcium ion antagonists in sympatholytic treatment of circulation disorders of extremities, e.g. hypoxia
Inventor: CLASBRUMMEL BERNHARD
IPC: A61K38/17
Filed: 1989-08-09
Abstract: Use of omega-conotoxin GVIA (omega-CT); (I) or an omega-CT analogue (II) is claimed as sympatholytic agents. The sympathicolysis is pref. peripheral intravenous or intra-arterial.  (I) and (II) may be administered together with Na-EDTA or a local anaesthetic e.g. lidocaine. USE/ADVANTAGE - In the treatment of sympatholytic reflex dystrophy, prim. or sec. Raynaud's syndrome, prim. fibromyalgia, in the 3rd and 4th stages of arterial occlusion (FONTAINE) and to improve circulation after hand or foot surgery or skin transplants. (I) and (II) may also be used for diagnostic sympathicolysis. Unlike guanethidine, which is commonly used in intravenous sympathicolysis, (I) and (II) do not induce super-sensitivity to noradrenaline. They achieve a full N-calcium canal blockade and noradrenaline inhibition after 1.5 log-stages (Clasbrummel et al; 1989. Inhibition of noradrenaline release by omega-conotoxin GVIA in the rat tail artery. Br. J. Pharmacol, 96, 101-110).

Title: Secure hoist mountings on steel heat treatment unit - has segmented support ring to accommodate thermal stresses and various design for attaching mountings to mantle's tank top
Inventor: BAETZEL HANS
IPC: C21D9/00
Filed: 1989-08-16
Abstract: Externally heated protective stainless steel mantle esp. for annealing workpieces under a protective gas atmosphere is sealed by an upper tank top having the novelty of an attached carrier ring divided into ring segments. The segments are positioned radially on the tank top by mountings (6,7), separated form one another by a circumferential distance and by a distance "b" from the tank top in conjunction with an outflow (9) for cooling liquid fed from above. The mountings (6,7) are formed from elongated baffle deflector plates (12) connected at one to the tank top (3) of the mantle and at the other end to the ring segments. ADVANTAGE - The use of individual rings segments to accomodate expansison and contraction and the solidity of the support construction improves safety and thereby minimises the danger of damage to personnel arising from fracture of the support ring leading to the mantle falling from the hoist.

Title: Rotatable multispindle drill head - has outer locking sleeve enabling drill head to be rotated by programmed movement against stop
Inventor: HOLZ PETER
IPC: B23Q5/04
Filed: 1989-09-28
Abstract: Existing multi-spindle drill heads used on machining centres can be translated from point-to-point on the work but the drilling patterns cannot be rotated.  In a representative form of the invention the housing (19) of the drill head has a cylindrical extension (21) through which passes the input drive shaft (22).  Rotatable on the extension (21) is a sleeve (29) which has  next to it a friction disk (39) secured to the extension.  The sleeve and extension are normally locked against relative rotation by the pressure of a spring loaded bolt (36) bearing against the friction disk. When the drill head is inserted in the spindle nose a torque reaction pin (18) on the machine frame pushes back a spindle locking pin (33) and prevents rotation of the sleeve (29) and housing (19).  However, the housing can be released by bringing the bolt (36) against a stop (43) on the machine frame.  A toothed disk (42) also engages with the stop (43) and by programmed movements along the machine axes the drill head can be rotated a required amount. USE/ADVANTAGE - A computer drill head fitting into a conventional magazine can be used to produce a variety of complex hole patterns.

Title: Lockable differential device - has movable clutch half turning with planet carrier and fixed to output shaft
Inventor: PAUL MICHAEL DR
IPC: B60K23/04
Filed: 1989-09-30
Abstract: The lockable differential comprises a planet-carrier (1) fixed in position in the axial direction and driving two sunwheels (10,11) via planetary pinions (8).  Each sunwheel drives an output shaft (14,15) movable in the axial  direction.  A clutch (18) with halves (19,20) fixed and moving in the axial direction couples the carrier to an output shaft (15). The movable clutch half (20) turns with the carrier and the fixed one (19) with the output shaft. ADVANTAGE - The axial friction forces in the axial driving faces of the output shaft cannot be transmitted to the moving clutch half.

Title: Magnetic accessory attachment aid for spectacles
Inventor: STEMME OTTO DR
IPC: G02C9/00
Filed: 1989-10-05
Abstract: To enable extra lenses (30,32) to be secured to a pair of spectacles in front of the normal lenses (18,20) a magnetic connection (22) can be incorporated in the frame (2) e.g. in the bridge piece (16). One magnet (36) is housed inside a bridge piece connecting the extra lenses (e.g. for sunglasses) and the other magnet (34) is in the main bridge piece.  Permanent magnets having high characteristic values such as energy density and permanence are incorporated, using alloys contg. at least one rare earth element and/or cobalt and/or by making them magnetically anisotropic. Their volume and weight are low enough for incorporating in the frame.

Patent DE-4013411-A1 (DE)
Inventor: KERZ LUDO
IPC: H04N1/405
Filed: 1990-04-26
Abstract: A process is disclosed for digitally screening half-tone images, in particular a chromatic component (plan) for a recording device that scans a recording medium along scanning lines. Density threshold value signals (screen signals) are continuously read out of at least one data storage for the scanning direction, then in a perperdicular (advancement) direction thereto. In the data storage are recorded the density threshold values of a section of a screen turned in a direction opposite to the scanning direction. The limiting lines of the section extend in the scanning direction and in a perpendicular direction thereto. In the section are periodically arranged several adjacent and superposed screen points (spots) that form a multiple reference cell (supercell). The base period of this screen point structure is contained maximum once in each of the two above-mentioned directions. The density threshold value signals read out of the data storage are compared with tone value signals (image signals) and control depending on the result of the comparison the luminosity of the recording device. In order to store a greater number of screen parameters (screen angle and widths) in the data storage, only the density threshold values of a reduced section, used as reference area (23), are stored for each screen parameter in the data storage. In the reduced section, the base period of the screen point structure is continuously contained once in only one of the two above-mentioned directions and can be joined to the first with an offset in the other above-mentioned direction.

Title: Flywheel energy storage unit with transformerless frequency converter
Inventor: STUKENBROCK HEINER
IPC: H02K7/02
Filed: 1991-01-24
Abstract: The energy generated in short bursts by the heat engine is buffer-stored in the flywheel on which revolving and pref. permanent magnets constitute the rotor magnets of a synchronous machine in cooperating with stator coils.     When the flywheel is run-up to max. speed the heat engine is stopped and the electrical load is supplied with energy while the flywheel runs down.

Title: Acid-resistant flooring prodn., with ceramic tiles on mortar bed -  by pouring unfilled, liq., resin-based cement concentrate into the joints, then adding inert granular fillers
Inventor: RUNDMUND THEO DIPL ING
IPC: E04F15/02
Filed: 1991-04-06
Abstract: Prodn. of acid-resistant flooring comprises laying ceramic tiles in partic. on a mortar bed and filling the joints with acid-resistant cement. The novelty is that an unfilled, low-viscosity acid-resistant cement concentrate (I) is first poured into the joints, which are then packed with inert, granular fillers (II). More specifically (I) is an unmodified, unformulated acid-resistant cement based on a 2-component synthetic resin mixt., e.g. epoxy, polyester, furan, acrylic or vinyl resin etc., or on a 1-component resin such as polyurethane etc.; (II) are mineral fillers with particle size below the width of the closest joint; residues of (II) are removed from the tile surface; alternatively (I) is poured onto the surface and (II) is then sprinkled on, dispersed in the cement and introduced into the joints. USE/ADVANTAGE - The invention provides a simpler and less labour intensive process (w.r.t. prior-art methods) for the prodn. of acid-resistant floor coverings, which ensures not only that even very tight joints between the tiles are filled, but also fills any open pores, cracks and splits into which acids and other liqs. could penetrate.
