Title: Safety binding for foot loops on surfboards
Inventor: NORDMANN KLAUS
Filed: 1981-02-09
Abstract: The invention relates to a safety binding for foot loops on surfboards which serves to avoid injuries to the ankles and knee joints as well as the adjacent bones due to falling when windsurfing with foot loops. Compared with the usually firmly anchored foot loops, the foot loop fastened by means of the present invention to the windsurfing board is released from its anchorage at the side subjected to the higher load in each case before the surfer is injured by overloading of his lower extremities. The aim was to obtain a releasing behaviour functioning in all loading cases and the adjustability of the release force. To achieve this object, a device is provided which in principle consists of a lever (1) which is suspended in a spring catch (5) (see drawing, Figs. 1 & 2) and to which the foot loop (2) is fastened in turn. Elements shown in the drawing:     1 Lever   2 Foot loop   3 Retaining plate   4 Two nuts with screws   5 Spring catch   6 Housing   7 + 9 Adjusting and retaining screws   8 Adjusting nuts   10 Rows of holes in foot loop 2   <IMAGE>

Title: Ski brake
Inventor: KLUBITSCHKO GERD DIPL ING
IPC: A63C7/10
Filed: 1981-02-23
Abstract: A ski brake has the form of a two-armed lever whose pivot axis is arranged on the surface of the ski, at least approximately at a right angle to the longitudinal axis of the ski. One arm of the lever can be actuated by a pedal to be activated by the ski boot, and the other arm is divided and forms two brake wings arranged on the outside of the ski. The ski is spring loaded in such a manner that, when the ski boot is removed from the ski, it automatically adopts its braking position, whereas in its ineffective position the two brake wings lie parallel to and above the top of the ski and are drawn in towards each other. In order to improve and structurally simplify such a ski brake so that it is more economical to manufacture and also functions more safely, the actuation arm (5) of the lever, the two brake wings (9) and the connecting rod (19) are each formed from a piece of twisted wire. Each brake wing (9) bears a sheathing designed as a bearing. Two tension springs (22) are provided, suspended on the side of the ski, each of which engages directly on a brake wing (9). <IMAGE>

Title: Hop extracts and process for the production of the same
Inventor: GOLDSTEIN HENRY
IPC: C12C3/12
Filed: 1981-07-04
Abstract: A process for the production of a hop preparation. The process is characterised in that it succeeds without addition of organic solvents. In this process an aqueous reducing solution is added to a crude hop extract and the resulting mixture is heated. Acidifying the reaction mixture forms an aqueous phase and an organic phase. The temperature of the reaction mixture is then adjusted so that the separation of the aqueous phase from the organic phase is facilitated, after which the individual phases are isolated. The water-soluble fraction is suitable for the preparation of an anactinic malt beverage, while the water-insoluble fraction can be used as an anactinic brewing copper additive.
