Patent DE-2111887-A1 (DE)
Title: Paper web flame primer
Inventor: HAROLD FLYNN JOHN
IPC: B29C65/10
Filed: 1971-03-12
Abstract: In a process for coating a paper web with a polyolefin layer, the web is primed prior to passage through the coating device by directing the tip of a high intensity stiff flame against the surface to be coated. The flame causes a decrease inpolarity in the cellulose of the surface fibres thus rendering them more amenable to the polyolefine. Where speeds of web movement. =1200 ft/min is used only one burner is needed; but where speeds above this are used, then two burners in sequence are needed.

Title: Universal weather resistant concrete table for outdoor use - comprises upper part with central recess and supported on concrete frame
Inventor: TRETTER HEINZ
IPC: A47B37/04
Filed: 1973-09-19
Abstract: The upper part of the table consists of a concrete plate with a central recess (for grilling equipment etc.) whilst the lower part is formed from an H or U-shaped concrete part which is connected at its free arms to the underneath of the upper plate. The concrete table is thus both weather and heat resistant which is particularly expedient if the centre recess is to be used for the grill whereby sufficient draw for the grill is ensured by an uninterrupted supply of fresh air coming up from below. The edge of the concrete plate may be reinforced which cuts down the thickness and thus weight of the concrete plate. The central recess can also be used to house garden umbrella holders or games boards instead of grill equipment.

Title: Concrete anchor coupling - has end of oblong eye accommodating anchor curved through more than 180 deg.
Inventor: ERHART DIETER
IPC: B66C1/66
Filed: 1974-04-11
Abstract: A supporting member in the form of an oblong eye is linked to the half-eye of a supporting plate having hooks on the other side engaging behind the anchor head. The plate and half-eye are split centrally along a line at right angles to the eye axis to allow the hooks to be fitted to the anchor head. The inner radius of the oblong eye is approximately equal to that of the supporting face of the half-eye. The inner curve in the oblong eye extends for an angle greater than 180 deg., and in the outer periphery of the half-eye is a trough-shaped recess for one of the shanks of the oblong eye. This reduces the thickness of the half-eye rib at this point to less than that between the opposite shanks of the oblong eye.

Title: Wear and noise reducing gear profile - has central slot cut into inner section of tooth profile
Inventor: LAUE GUENTER PROF DIPL ING
IPC: F16H55/16
Filed: 1974-06-26
Abstract: The design provides high mechanical efficiency of transmission especially for fluctuating load factors. It is used on involute wheel faces on steel gears, for example in vehicle and machine tool gear boxes. The advantage claimed is that the maximum loading between the teeth faces on gear change is reduced, thereby decreasing stress corrosion (pitting). Oscillations in the system are reduced and hence the noise generated. The principal feature of the gear tooth is that there is a slot with near parallel sides in the cross sectional surface. The cut away section reduces the cross sectional area by up to one half. The slot only slightly reduces the stiffness of the tooth. The slot is cut symmetrically in the tooth centre.
