Title: Stabilisation of sterilised pharmaceutical solns. - by adding phosphinic acid or its salt or ester prior to sterilisation to protect components sensitive to oxidn.
Inventor: BUESING GERHARD DR
IPC: A61K47/02
Filed: 1990-09-14
Abstract: The stabilisation of sterilised pharmaceutical solns. with components sensitive to oxidation comprises adding phosphinic acid or one of its salts or esters to the soln. to be sterilised prior to sterilisation. The phosphonic acid/phosphinate concn. is 1-50 (esp. 15) mmol/l. The phosphinate is an alkali or alkaline earth metal salt, esp. sodium phosphinate. An additional antioxidant, esp. an organic S-cpd. ascorbic acid or Me of its derivs. or a riboflavin deriv. is added to the soln. prior to sterilisation. The organic S-cpd. is cystein, thiolactic acid, thioglycerine, dithioerythritol, thioglycolic acid, methyl(thiouracil, thiourea, thio malic acid or esp. N-ethanoylcystein. The second antioxidant is added in an amt. of 0.01-10 g/l. A chelate former is added to the soln. prior to sterilisation. A stabilising combination consists of 15-30 wt.% sodium phosphinate and 85-70 wt.% N-acetyl cystein. USE/ADVANTAGE - The phosphinic acid based stabilisers are effective and cheap replacements for sodium disulphite, which can cause allergies in some patients and even anaphylatic shock. Phosphinic acid and phosphinates are toxicologically acceptable and are not known to cause allergic reactions. The stabilisers can be used in pharmaceuticals solns. such as infusion solns.

Patent DE-4100103-A1 (DE)
Inventor: STOLTE JOHANNES
IPC: H04N3/22
Filed: 1991-01-04
Abstract: In connection with HDTV and 16:9 image transmission there are special operating modes in which the vertical scanning amplitude in the overscanning sense is so great that only a part of the vertical scanning time signal covers the full image height. Owing to the greatly increased deflection angle, the electron beam can strike the neck of the cathode-ray tube (CRT) and damage the CRT itself. The intention is to prevent such CRT damage and reduce the power loss in the vertical final stage and the vertical deflection coils. The control generator (2) is designed so that, in a special operating mode, the increase in the deflection current (ia) beyond the maximum (ian, iap) is reduced in relation to the increase between the maxima. Especially for television receivers with special operating modes with increased vertical scanning amplitude.

Title: Two=stage conversion of used oil for Diesel oil prodn. - comprises heating with light solvent and then heating in electrically heated metal container with heat distribution system
Inventor: OBERT HERRMANN EDUART
IPC: C10G9/24
Filed: 1991-08-24
Abstract: This is a system for the two-stage conversion of used oil or other residual oils for, predominantly, the prodn. of diesel oil. In the first stage, the oil is heated to about 120-250 deg.C, and the light prods.; such as water, petrol and solvent, evaporate. In the second stage, the preheated oil is heated in an electrically-heated metal container having a heat distribution system (e.g., chamotte or sand). Depending on the type of oil used, temps. of 350-500 deg.C are produced. Temps. of about 600-700 deg.C are regulated in the electrically heated heat- distribution bed. The container is insulated, and the oil in it, during the cracking process, becomes frothy with the froth occupying 40-60% of the container capacity. Cracking residue is removed from the container walls with a cracking worm and from the container by a conveyor worm. A number of variants are claimed for the method and the plant, and include the use of ultrasonic sensors. USE/ADVANTAGE - Optimum utilisation of used oils, and of residues such as polymerisates or residual tars, is provided for producing diesel or light fuel-oils with a minimum of other resultant prods. (earlier methods have environmental drawbacks). The arrangement is transportable.

Patent DE-4140607-A1 (DE)
IPC: E06B9/174
Filed: 1991-12-10
Abstract: The winding shaft (12) of an awning (4) is mounted at the ends in bearing brackets (11) which are designed in an identical manner. Each bearing bracket (11) has a plug-in opening into which a bearing carrier (35, 58) for the winding shaft (12) can be inserted from above. With respect to a plane of symmetry on the axis of the winding shaft (12), the bearing bracket (11) is provided in an essentially mirror-inverted manner and can thus be used as both a right and left bearing bracket (11). In order to retain the bearing carrier (35, 58) in the opening (19) of the bearing bracket (11), the side edges of the opening are provided with V-shaped grooves (27). In order, in the case of awnings with a positive return means, to avoid alignment errors between the respective drawing-band pulley and the guide tube, at least one of the drawing-band pulleys is mounted directly, and independently of the winding shaft (12), on the respective bearing bracket (11). <IMAGE>

Title: Noticeboard providing information for motorists - has metal sheet connected by cross members and having rows of holes in its surface to reduce wind resistance
Inventor: KING SIEGFRIED DR MED ING GRAD
IPC: G09F7/00
Filed: 1992-03-12
Abstract: The noticeboard consists of a rectangular sheet of metal (1) attached to vertical supports (4, 6) connected by cross-members (5) and (7). Rows of holes (3) are formed in the metal sheet but are of such a size and number that they do not affect the legibility of the information displayed on the noticeboard. The holes reduce the wind resistance of the structure. The holes may be distributed uniformly over the entire surface of the board or they may be restricted to those areas not covered by the inscription. USE/ADVANTAGE - For giving directional information to towns or to rest areas. Because of the reduced wind resistance, lighter and cheaper supports can be used.
Patent DE-4209784-A1 (DE)
IPC: B65D47/12
Filed: 1992-03-26
Abstract: The invention concerns a closure for a container, comprising a lower portion (20) and a screw cap (10). The lower portion can be connected to the container opening by a base unit (21) and has a pouring spout. The said spout is connected to the lower portion by elastic extensible bellows (22), and the screw cap with the cap base and the cap casing, which is provided with an inner screw thread (13), can be screwed on and off the pouring spout, which has an outer screw thread (24). As a simple child-proofing feature, the pouring spout of the lower portion is provided with at least one stop lug (26) outside the outer screw thread in the transitional area facing the bellows, the said lug has a flat leading edge (27) in the screw-on direction and becomes a steep detent edge (28), so that the cap casing is locked with the stop lug in the screw-on position and prevents the screw cap from being unscrewed. By depressing the bellows in the region of the stop lug, the engagement of the screw cap with the pouring spout can be broken and the screw cap can then be unscrewed.

Patent DE-4219364-A1 (DE)
Inventor: BAE TAE SUG
IPC: G11B27/19
Filed: 1992-06-12
Abstract: In order to ensure that the tape travel display 70 of a video cassette recorder remains accurate during repeated starting and stopping of the tape transport mechanism of the video cassette recorder, tape travel is monitored during threading and unthreading of the tape by counting pulses generated by a reel sensor 60 which outputs pulses as a function of the rotation of a tape reel. The number of pulses produced by the reel sensor 60 during unthreading is stored and is used during subsequent threading to ensure that counting of control pulses recorded on the tape starts when the tape is in the same condition as when unthreading began. <IMAGE>
