Title: Vacuum cleaner fan for hand tool waste exhaust - has additional opening ensuring adequate cooling of motor
Inventor: REIBETANZ WILBERT
IPC: F04D17/16
Filed: 1979-11-14
Abstract: In the fan for the vacuum cleaner the suction air is drawn through bores having a small diameter. In order to increase the amount of suction air, auxiliary air openings are provided. To prevent these openings from clogging a further auxiliary air opening (21) is provided, facing the fan casing (1) which houses the motor. This opening is pref. an oblong bore through a fan shaft (9) so that now even with a low air input sufficient cooling of the motor parts is ensured.

Title: Large slit row perforated building block - has concertina patterned cross arms and parallelogram slots in angled rows
Inventor: RANK HORST
IPC: E04B2/14
Filed: 1979-11-24
Abstract: Stem pieces running in the direction of heat flow are in the form of parallel partitioning walls, dividing individual rows of slits, in a perforated building block, esp. large folded brick (1). Slits (7...) in two adjacent rows (8...) in this direction (A) are inclined relative to each other, so that the dividing cross stems (11,12....) in the block's longitudinal direction (B) run in a concertina pattern, while the slits enclosed by them are parallelogram shape, cross stems are pref. at an angle of 10 deg to 20 deg. This reliably ensures that no fissures occur during cutting drying and/or firing, and there is no need to press cross stems with a cutting wire.

Title: Prepn. of purer calcium leucovorin - by treating anhydro-leucovorin with amine base in aq. solvent
Inventor: WISOWATY JAMES CHESTER
IPC: C07D475/04
Filed: 1980-01-25
Abstract: Calcium leucovorin (I) is prepd. by mixing anhydroleucovorin (II), an amine base and an aq. solvent. Then the mixt. is heated at pH 5-7 and an equimolar amt. of water-soluble Ca salt (III) (based on (II)) and isolating the (I). Because an amine is used for ring opening of (II), the (I) has lower impurity levels than when inorganic base is used. The (I) prod. meets U.S. Pharmacopeia specifications after being washed with water, and chromatographic purification etc. is not necessary. (I) is useful in dimininishing the toxicity and effects of overdoses of folic acid antagonists and for treating megaloblastic anaemias due to sprue, nutritional deficiency, pregnancy, infancy etc. and esp. for neutralising the toxic effects of methotrexate.

Title: Spectral analysis specimen table - is for small diameter steel and alloy specimens, and has table hole insert setting dia.
Inventor: TELSCHER FRIEDRICH
IPC: G01N21/67
Filed: 1980-02-25

The edge of the table opening facing the electrode has a peripheral shoulder (11) forming a stop and an entering surface for the hollow cylindrical insert.
Patent DE-3010469-A1 (DE)
Title: Hydraulic power pressure control for automatic gearbox - gives controlled pressure reduction during last stage of gear change
Inventor: STROH WALTER
IPC: F16H61/00
Filed: 1980-03-19
Abstract: The engine speed (10) and gear ratio weighted (12) output speed (11) are applied to a comparator (13) which feeds two level detectors (14,15) from its output. One detector (15) responds when the slip speed between the input speeds has reached a set value. At this point the pressure reduction commences. The point coincides with the speed at which friction is likely to increase rapidly. The second detector (14) responds when the slip is zero and restores normal working pressure to the drive. The degree of pressure reduction can be made load dependent by feeding a suitable signal (18) into a processing circuit (16) between the level detectors (14,15) and the hydraulic control valve (17). The modification to the hydraulic working fluid control system is intended to give a smoother gear change. By reducing the operating pressure towards the end of the gear change sequence the tendency for the friction clutch to transmit more torque and give a snatching action is reduced.

IPC: A61F9/06
Filed: 1980-05-19
Abstract: The safety visor used by welding gear operator, consists of two sections, each having parallel evenly spaced strips which are opaque to ultra-violet rays. As one section is moved across the other by the width of one strip, complete screening to ultra-violet rays is effected. Each of the two sections (2,4) have strips (3,5) of material which filters ultra-violet rays, applied to them. If one section (2) is moved vertically w.r.t the horizontal strips (3,5) or horizontally if the strips are vertical, an effective shield results.

Title: Dipped beam headlamp for motor vehicle - which offset upper and lower reflectors of different focal lengths in parabolic reflector
Inventor: PERTHUS PETER
IPC: F21V7/00
Filed: 1980-12-24
Abstract: The headlamp reflector is divided into upper (10) and lower (11) sections each of paraboloid form. The optical axis (31) of the lower section is directed downwards w.r.t. the corresponding axis (21) of the upper reflector. The light source is an incandescent lamp with filament coil (12) on the headlamp axis. The optical axes (21,31) cross at the centre of gravity (24) of the filament. The focal lengths of the two parabolic reflectors are such that their focal points (20,30) lie between the filament (12) and the rear of the reflector assembly (16). The resulting beam is one which is directed downwards (22,32;23,33), and then further modified by the headlamp lens (14). With the focal lengths and axes as stated the dimensional tolerances in filament and lamp manufacture become less important to beam positioning.

Title: Mounting for ski maintenance
Inventor: SCHWENK HANS
IPC: A63C11/02
Filed: 1981-03-13
Abstract: With such apparatuses, skis are secured on tabletops or similar supports for maintenance of the sliding surface (waxing or resharpening of the steel edges), so that they can be worked upon without impediment. This object is achieved by means of a suction cup whose suction side points upwards in the working position. The suction cup is secured on a support which can be attached to the fixed base by means of a releasable securing device. In a special alternative embodiment of the mounting, the support is formed by a block, through which a round rod passes. The round rod serves as a collet chuck at the lower end, and a clamping piece engaging round the round rod is arranged in a recess in the block and tilts an eccentric lever towards the round rod against the pressure of a spring. Attached to the support in front of the suction cup, transversely to the direction of the ski, is a strip of rubber/plastic which stabilises the ski laterally against tilting. Two mountings, arranged at a distance apart, are used to mount a ski. The skis are laid and pushed onto the suction cups, which hold them in a non-slip manner, with no danger of damage arising. It is unimportant whether the skis are narrow cross-country skis or wide downhill skis. <IMAGE>
