Title: Alkylating highly disperse silicon dioxide - after steaming to desired degree of wetting
Inventor: TSCHUIKO ALEXEJ ALEXEJEVITSCH
IPC: C09C1/30
Filed: 1975-10-17
Abstract: Highly disperse SiO2-alkyl prods. (I) are prepd. by alkylating highly disperse SiO2 with alkyl chlorosilane vapours in a turbulent layer process. SiO2-alkyl prod. obtd. is then sepd. from the gaseous reaction prods. at 390-400 degrees C. The novelty is that the highly disperse SiO2 is steam treated at 110-120 degrees C before alkylation. Steaming is continued until degree of wetting of SiO2 is 2-40 mk mol. H2O/m2 SiO2. Subsequent alkylation takes place at 250-310 degrees C, e.g. for 5-15 min. (I) having alkyl gp. degree of grafting 8 mg mol./m2 SiO2 are used as fillers for silicone rubbers without use of stabilisers. Prods. having alkyl gp. degree of grafting 6.7 mk mol./m2 SiO2 can be used as thickeners for lubricating greases. With alkyl gp. degree of grafting of 4.7 mk. mol./m2 SiO2, prods. can be used as additives which prevent caking together of NH4NO3, and as fillers for lacquers and paints. The alkyl gp. degree of grafting on SiO2 surface can be controlled. Wetting forms a hydrate layer on SiO2 surface. On treatment with alkyl chlorosilane vapours, triple bond Si-CL are hydrolysed to triple bond Si-OH gps., which can then react with OH gps. of SiO2 surface under gentler conditions, e.g. 250 degrees C, 15 min., instead of 400 degrees C, 0.5 hrs.

Title: Hydrostatic bearing with load dependant oil pressure - has deformable elastomeric plug to adjust oil flow to suit load
Inventor: WALTER LOTHAR
IPC: F16C32/06
Filed: 1975-10-29
Abstract: The main patent describes a hydro-static bearing in which the oil pressure is controlled by an elastomeric plug with two parallel capillary bores. This addit to the patent uses an elastomeric plug (1) with two parallel longitudinal slits (5). The slits communicate with transverse holes (7). The slits are connected to the oil supply and the holes (7) to the opposite sides of the bearing. If the load on the bearing increases, the consequent rise in oil pressure enlarges the slit supplying the oil and reduces the slit supplying oil to the opposite side so keeping the bearing in equilibrium.

Title: Friction lock for car rear door telescopic strut - has pair of semi cylindrical friction members in slot movable by manual pressure
Inventor: FIALA ERNST PROF DR
IPC: E05F3/16
Filed: 1975-11-03
Abstract: The telescopic strut, for supporting an upward swinging rear door of a car, has a rod sliding inside a tube. The end of the rod has a slotted hole. A pin which passes through this slot forms a pivot for two semi-cylindrical friction members. A spring forces the friction members against the bore of the tube. When the rod is pushed into the tube, the friction between the members and the bore creates a moment about the pin which increases the friction still further. As the rod moves inwards the spring is compressed until the arms are pressed onto the members exerting an opposite moment and limiting the force.

Title: Metal utensils enamelling - with flanges kept free from enamel by sandblasting and ceramic or metal spraying
Inventor: PENNERSTORFER WALTER DIPL ING
IPC: C23D5/00
Filed: 1976-05-25
Abstract: Flanges of enamelled domestic utensils such as pots and pans which are to be kept free from enamel are first cleaned and roughened by a sandblast or pickling operation. The flanges are then metallized by flame spraying with a ceramic or metallic coating. The surface areas which are to be enamelled later are marked during this operation. Prior to the firing, any slip on the flanges is removed by wiping. This eliminates the unsightly fringes where the enamel has wasted away. It saved the grinding operation which requires extreme care to prevent the enamel from splintering off.
