Patent DE-2556493-A1 (DE)
Title: Adhesively fixed wall anchor bolt - uses helical web to influence adhesive flow behind outer sealing ring
Inventor: HARKE ALFONS
IPC: F16B13/14
Filed: 1975-12-16
Abstract: The anchor bolt is for insertion into a bore, and has a channel with an opening, for application of an adhesive. After hardening, the adhesive connects the bore wall and the bolt, which has one or more sealing rings to limit the length of adhesion. The bolt surface (1) has a projection to influence the adhesive which flows between the bolt and the bore hole wall (3). The projection may consist of a helical web, extending opposite to a thread of the bolt outside the bore, and which forms the channel. The bolt may have an additional channel, which extends over only part of its length. The channel aperture may be sealed by a sealing ring.

Title: Key for fixing wheels to shafts - has rounded ends to prevent damage to components during fitting and has square centre portion
Inventor: ROETTEL FRANZ
IPC: F16D1/08
Filed: 1976-04-23
Abstract: The key (1) which is intended for fixing wheels or rotors to shafts is of square cross-section with hemi-spherical ends (3)(4). The ends (3)(4) are formed by turning with a chamfer (5)(6) between the corners of the square section and the spherical surfaces (3)(4). With this type of rounded end there is no danger of damage to either wheel or shaft during fitting, if the key should not be fully inserted into the keyway. The idea can be adapted to suit keys of rectangular cross-section by making the end of the key semi-circular and then rounding the edges formed by the faces of the key and the semi-circular end.

Title: Antimicrobial, antifungal aliphatic carboxylic acid compsns. - are partially neutralised to form complexes with ammonium and/or metal ions and avoid odour and corrosion problems
Inventor: HUITSON JOHN JACKSON
IPC: A61L9/01
Filed: 1976-11-25
Abstract: Liq. compsn. contains ammonium ions and/or metal ions of a Gp. I or II element, >=1 carboxylic acid chosen from formic, propionic, n-butyric, isobutyric, 2-methylbutyric, valeric, levulinic, acrylic and methacrylic acids and water. The ratio of acid to ammonium and/or metal ions is between 2-4:1 on the basis of chemical equivalents. Aliphatic carboxylic acids are used in industry and agriculture e.g. as preveservation agents for animals feeds and crops etc. to avoid growth of mildews, bacteria and cryptogames. They may be added to barley, wheat, oats, rye, maize, rice, hay, straw, silage, dried grass, dried beans, soya, bagasse, sunflower seed, cane sugar, colza, peanut, fish meal, bone meal waste, sawdust, animal excrement etc. They may be used to descale pipes and boilers, as buffers in photography and to treat cryptogamic infections such as Athletes foot. The solns. contg. Na and K ions may be used as anti-gelling agents and those contg. Cu ions for protection of wood and as fungicides in vineyards. The present compsn. reduces the obnoxious odour of the free acids to a minimum and avoids corrosion problems without loss of the desired, activity of the free acid. Complexes are formed between the acid and base which are stable in aq. soln. and reduce vapour loss w.r.t. to the free acid. When used as an antimicrobial pref. 0.1-5 wt % of the compsn. is used based on the substrate.

Title: Vehicle tyre with side studs and grooves - with studs joined by circumferential webs in shoulder zone
Inventor: HEIDEGGER HERBERT DIPL KFM
IPC: B60C11/01
Filed: 1977-05-17
Abstract: Vehicle tyre comprises side studs and side grooves, of which the former are connected to each other in the shoulder zone by circumferentially extending webs (1) in alignment with the studs. Each web pref. has an approx trapezoidal cross-section tapering away from the base. If the tread surface is worn away down the web, a greater width of adherence, and a gradual transition from the new studs to the stud base of the old tyre, are obtained. The unattractive appearance of a conventional renewed tyre is eliminated, and the impression of a new tyre is provided. The trapezoidal shape allows unobstructed exit of slush or water from the stud grooves, and the more flexible tip of the web allows mechanical stress to be stood more readily.
