Patent DE-4023860-A1 (DE)
Title: New sterically hindered di:phenyl pyrazoline cpds. - are used as scintillator having large strokes shift, good quantum yield and decay time
Inventor: GUESTEN HANS DR
IPC: G01T1/204
Filed: 1990-07-27
Abstract: New sterically hindered 1-phenyl-3-(2',6'-dimethoxy)-phenyl -2-pyrazoline derivs. (I) are of the formula (I), where R1 = an electron donor substit.; and R2 = Me, OMe or H. The prepn. of (I) is also claimed whereby beta-dimethylamino-2,6-dimethoxypropiophenone (II) is reacted with a phenylhydrazine deriv. of formula (III). USE/ADVANTAGE - (I) are claimed for use as scintillators. They are useful in large chambers or in polymer scintillation fibres.  Their fluoroescence emission and absorption wavelengths are further apart than usual, so that overlap occurs only at very high (I) concns. in soln. The fluorescence quantum yield and decay time are in the favourable ranges of known derivs.

Title: Drawer slide with impact absorbing wedge inserts - has rubber wedge inserts in indented region of rail horizontal flange to absorb kinetic energy of drawer movement
Inventor: FULTERER MANFRED
IPC: A47B88/493
Filed: 1990-09-12
Abstract: The drawer slide comprises relatively sliding rails (1, 13, 24) with rollers (18, 27) between them and stops (8, 21, 22, 26) to limit their relative movement. In the rail section directly before the roller of the counter part rail reaches its ends position a rubber insert (9) is mounted to provide a tapering rail section and thus check the movement of the roller. The insert is formed from a flat surfaced wedge mounted entirely in an indented region of a horizontal flange of the rail. USE/ADVANTAGE - Drawer slide allows use of larger damping insert to absorb noise of impacts.

Title: Brake circuit for aBS and wheel-spin control - has two non-return valves and single servo pump
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T8/48
Filed: 1990-10-05
Abstract: The single servo pump (10) has two non-return valves (16,17) on a sliding mounting operated by the pressure from the master cylinder (1). The main valve (16) opens above atmospheric pressure while the second valve provides a path between the top-up reservoir (13) and the pump. The first non-return valve ensures that the pump does not receive such air. The master brake cylinder is isolated during wheelspin control by shut-off and of non-return (20) valves. ADVANTAGE - Only one servo pump required; fail-safe operation.
Patent DE-4031926-A1 (DE)
Inventor: HOERMANSDOERFER GERD
IPC: A61F2/34
Filed: 1990-10-09
Abstract: The invention relates to a screw-in acetabular prosthesis (1) of spherical geometry with a special thread for cementless implantation, and to a method for its manufacture. The special thread follows in its pattern the spherical circumference formed by the nominal diameter of the cup (1) and is almost completely adapted in its base to this spherical circumference by virtue of the fact that the layout of the thread base is adapted to a very great extent to the spherical outer contour of the acetabular prosthesis (1) by means of strip-shaped part surfaces which are divided into steps in terms of angle and which extend parallel to one another and obliquely relative to the layout of the thread base. The special thread is cut according to the invention by machining with a number of tools, with different cutting edge angles in relation to the thread base (6, 7, 8), and on different paths. Compared to conventional spherical screw-in cups, the thread configuration according to the invention, by means of the freely available thread tooth depth, affords a substantially better primary fixation upon implantation and at the same time considerably reduces the risk of loosening by virtue of the fact that, as a result of the complete contact between the surface of the cup and the bone over a large area, only low specific forces act on the bone bed. <IMAGE>

Inventor: LIEBICH MAX
IPC: A24C5/40
Filed: 1990-11-07
Abstract: The description relates to a system for the rolling of cigarettes by the consumer in which a semi-finished product (1) not smokable per se in the form of an encased plug of tobacco (2) (''cigarette tobacco cartridge'') is used. The semi-finished product contains a tobacco filling (2) corresponding in shape, size and quantity to a cigarette in a cylinder of cigarette paper (3) of the customary weight; the non-smokable property of the semi-finished product as such is ensured by a perforation (4). The final cigarette is made from this semi-finished product by the consumer in that the perforation on the semi-finished product is subsequently sealed by a separate adhesively coated cover strip (6). To make handling easier, the (narrow) cover strip (6) may be fitted with a wider gripping tab (7) which can be separated after sticking by means of a microperforation (8). The cigarette thus obtained has the structure, material composition and smoking properties of an ordinary industrially produced filter cigarette. The making of the cigarette by the system of the invention can be facilitated by a simple device or a simple aid (50) consisting of a lower section (51) with a trough (54) and a cover section (53) hinged thereto.

The bobbin carrier is a suspension path, with a vertically rotating frame (9) and an adaptor (13) to fit the conveyor. A locking unit (10) at the frame has locking units (3) at intervals matching the distribution of bobbin holders at the next processing station. Guides (4) are at intervals of less than half the gap between the workstations of the winder, where one guide is vertically displaced in relation to the other. USE/ADVANTAGE - For use when changing wound bobbins of man-made filaments of the winder, the assembly gives an effective bobbin handling action independently of the floor layout, to give an automatic bobbin change and transport operation.

Title: Electronic control system for vehicular braking or traction - reacts to detected wheel speed difference in periods free from steering, hill-climbing, wheel-slip or lock
Inventor: HOLST HANS DIPL ING
IPC: B60K28/16
Filed: 1991-04-29
Abstract: The brake cylinders of all four wheels are supplied via magnetic valves controlled by a microprocessor in which individual wheel speed signals are digitised (11). The percentage difference (12) of average speeds of front and rear axles allows for uneven tyre wear and deviation from the straight. At a lower threshold of difference the wheel speed signal is compared (22) with a road-speed reference. Warning is given (10) if the difference exceeds a higher threshold for a significant duration. ADVANTAGE - Quality of control is improved against insignificant but persistent speed variations among individual wheels.

Title: High sphericity ceramic ball mfr. - by two=stage fluidised bed granulation
Inventor: DOBRAS PETER DR
IPC: C04B35/111
Filed: 1992-01-22
Abstract: Prodn. involves: (a) doubling the particle size of a ceramic starting material, with a particle size of 25-50% of the desired ball dia. by fluidised bed treatment; (b) increasing the particle size of the resulting material to the final ball dia. by spraying with a thin ceramic suspension of max. 30 wt.% solids content for a long dwell time in a fluidised bed granulator, the suspension binder content and the fluidised bed density being controlled to achieve equilibrium between granulate accretion and wear in the target ball size range; and (c) sintering and opt. post-treating. USE/ADVANTAGE - The process is used to produce 0.5-2 mm dia. ceramic balls, e.g. for use as grinding bodies, surface blasting material or ballpen ball tips.

Patent DE-4206661-A1 (DE)
Inventor: STOCKHAUSEN HORST-DIETER DIPL
IPC: F16K17/38
Filed: 1992-03-03
Abstract: In a safety device against the failure of a nuclear reactor pressure vessel due to the overpressure that results from insufficient cooling of the core, a temperature-dependent pressure discharge is provided. A differential pressure-loaded pressure discharge fitting (22) set in a wall of the pressure vessel (1) exposed to the primary pressure or the immediately adjacent piping has a closure piece movably mounted in the longitudinal direction, in particular a differential pressure piston (23), retained in its closure position by a fusible soldered stop (24, 25). When an upper threshold temperature is reached in the inside of the reactor, that leads causes the soldered stop is caused to melt because of a heat flow that reaches it at the threshold temperature and the differential pressure piston (23) moves into its opening position. The pressure discharge line (28) may also be designed as a control line (28) for a separate blow-off valve (36), if the cross-section of the pressure discharge fitting and of the lines connected thereto is correspondingly reduced.
