Patent DE-4131486-A1 (DE)
Inventor: SCHNEIDER JOACHIM
IPC: F16H25/22
Filed: 1991-09-21
Abstract: The invention relates to a ball screw in which balls (13) are arranged between the thread (2) of the spindle (1) and the thread (4) of the nut (3). The thread (4) of the nut (3) extends approximately over a pitch and hence a spire. Both ends of the thread (4) are interconnected via a transfer channel (6). The thread (4) is constituted by a component (5) in the shape of a tin sleeve from which are stamped tabs (8) which are bent inwards and form the side surfaces for the transfer channel (6). The component (5) is shaped into the nut body (7) formed as an injection-moulded plastic part. This provides a particularly economical and free-moving ball screw. If the helical threads (2) and (4) of the nut (3) and spindle (1) at the core and inside or outside diameters are rounded, there are favourable transitions for the transfer of the balls to the end of the thread (4) or the transfer channel (6).

Variants include a container (5) in which there are 3-7 rollers (pref. of Al alloy) at two or three levels at or below the suspension surface, and which has a cooling system. Rollers may have turbulence-producing vanes. Steel strip goes from the feed stand (1) to a bitumen box (2) equipped with heating and with a worm conveyor and contg. coating nozzles (3) and a felt skimmer (4). Steel strip has been immersed in the bitumen, then taken to the open-top box (5) which contains 5 rollers (7) for taking, several times, the bitumen-coated steel strip along a large arc of contact at two or more levels. Surplus parting cpd. suspension is removed from the strip by the brush (6), after the strip has left the bath. After this, the strip is taken via a hot-air dryer (8) and guide rollers (9) to the winding stand (10). USE/ADVANTAGE - System applies, with simple equipment, the parting cpd. uniformly and dust free.

Patent DE-4140557-A1 (DE)
Inventor: RUDOLPH BERND
IPC: H05B41/295
Filed: 1991-12-09
Abstract: The invention relates to a circuit for operating one or more low-pressure discharge lamps. For each lamp (LP) there is a heating circuit consisting of the electrodes (E1, E2) of the lamp (LP) and a relay contact (K). During the preheating stage, the switch (S), preferably taking the form of a threshold switch, detects the rectified, smoothed voltage of the electrode coils (E1, E2) and, if the electrodes (E1, E2) have preheated sufficiently, opens the relay contact (K) via the relay coil (RL). In another preferred embodiment, the relay is replaced by a field effect transistor which is switched off at the end of the preheating stage by an electronic switch which assesses the voltage drop across the electrode coil (E1). The circuit arrangement of the invention permits the best possible preheating of the lamp electrodes in an economical manner.

Title: Coupling optical fibres to optical component for communications system - arranging bare fibre ends in unit over grooves then lowering into grooves for connection with component terminals
Inventor: WETZELS RALF DIPL PHYS
IPC: G02B6/42
Filed: 1992-05-27
Abstract: The method involves connecting the fibres (21) to a unit which comprises a polymer base (10) formed in one piece but having at least two sections, and a cover (31) for the base (10). The central section (11) of the base (10) has wave guides (17) forming individual components. The outer section (12) has grooves (14) to receive the fibres (21).

Then, the fibre ends (25) are all cut across. The set (22) is arranged with the fibre ends (25) over the grooves (14) in the base (10) and lowered into the base (10). The fibre ends (25) are precisely adjusted by the groove edges (47). Finally, the cover (31) is brought into place. This presses the fibre ends (25) into the grooves (14) and fixes them in place. The core (46) of the fibres (21) are aligned with the components inputs (18) and outputs (19). ADVANTAGE - Ensures quick coupling for low-cost assembly.
Patent DE-4219403-A1 (DE)
Inventor: VOGELSANG HORST
IPC: H02G9/06
Filed: 1992-06-13
Abstract: A cable guiding device having at least one cable guiding pipe (conduit) of thermoplastic synthetic material, which cable guiding pipe has a cable guiding duct with a duct inner wall (which is circular in cross-section and has the pipe internal radius r), and which has sliding ribs which are arranged on the duct inner wall and are formed out of the thermoplastic synthetic material of the synthetic material pipe. The sliding ribs run at a predetermined rotation angle a with respect to the internal circumference. Contact surfaces having the rib contact width b result in a cable guiding pipe, which is arranged in a straight line, with a cable (which is to be inserted) at the contact points between the sliding ribs and the cable sheath of the cable which is to be inserted. The sliding ribs run in a corrugated shape and form reversing regions between sections having a constant rotation angle a. The rib contact width b, the number of sliding ribs which are distributed equidistantly over the circumference of the duct inner wall, the pipe internal radius r and the length LK of the rib contact sections between the reversing regions satisfy the equation Ar = 0.16 b<2>z LK. A defines the contact area of the cable sheath at the intersections with the sliding ribs in the rib contact sections. The angle g, measured in radians, of the pitch of the sliding ribs, measured on the duct inner wall, satisfies the equation g = ra/LK.

Title: New cytosine analogues with lipophilic protected amino gps. - for treatment of cancer and virus diseases e.g. AIDS, are more protected against enzymatic des-amination and can be used in higher doses than unprotected cpds.
Inventor: SCHOTT HERBERT PROF DR
IPC: C07H19/06
Filed: 1992-07-27
Abstract: Cytosine nucleoside analogues of formula (I) are new; R1 = acylated or alkylated amino, the acyl or alkyl gp. of which contains 8-24C and 0-2 double bonds and is opt. branched; R2 = H, F, Cl, Br, I or opt. branched 1-24C alkyl which contains 0-2 double bonds; R3, R4 = each H, F, Cl, Br, I, N3, OH or phosphate. USE/ADVANTAGE - (I) can be used in the treatment of cancer and virus-dependent infections, e.g. AIDS. (I) can be used to treat malign diseases of blood forming cells, esp. acute leukaemia and chronic myeloid leukaemia. The N4-amino gp. is masked with a lipophilic protecting gp. so that (I) is more effectively protected against enzymatic deamination. Compared to unprotected cytosine nucleoside analogues e.g. AZT, the dose of (I) can be greatly increased, without leading to an increase in the toxic side effects. (I) are prodrugs, and the slow conversion into the pharmacologically active substance enables therapy to be applied at intervals. (I) are lipophilic and can be dispersed in liposomes, thus widening the scope of methods of application. (I) have better cytostatic activity than 1-beta- D-arabino- furanosyl cytosine, less severe side effects and therapy can be applied at intervals.

Title: Calibrating sensor for measurement of solid content of solid-liquid mixtures and determining mixture material properties
Inventor: GUENTHER WOLFGANG DR ING
IPC: G01N33/34
Filed: 1993-01-18
Abstract: In the calibration method, the current measurement value of a sensor (TMS), which continuously measures the solid-liquid ratio of the mixture, is temporarily stored at the time of extraction of the specimen for the drying balance (ATW). The filter dewatering and drying times are measured during dry weighing and are stored for measuring e.g. the ash content.A correction factor (K) derived from the difference between the two stored values is used over a repetition interval to correct the current sensor measurement value until measurement of the solid content of the next specimen.
Patent DE-4303133-A1 (DE)
Inventor: MUELLER-KIRSCHBAUM THOMAS DR
IPC: B23Q11/10
Filed: 1993-02-04
Abstract: The concentration of the emulsion is monitored. To measure the concentration of the emulsion and/or its surfactant content and/or its current cleansing action, a bubble tensiometer operated with sufficiently constant gas flows is used to measure a value correlated to the dynamic surface tension. The measured values are compared with a predetermined reference value derived from a calibration for the cooling-lubricant emulsion in use. Depending on the results of the comparison, measures may be taken to refurbish the emulsion. The concentration of the emulsion is monitored continuously in an on-line process. The results can be recorded continuously. The process can also detect a diminution in the cleansing action of the cooling-lubricant emulsion when soilage builds up.
