Title: Ski brake with lever pivotal on ski - has locking mechanism preventing movement of brake when ski boot is removed
Inventor: SCHMIDT JOHANN
IPC: A63C7/10
Filed: 1976-07-21
Abstract: Theski brake has a brake lever, pivoted on the ski about an axis extending in longitudinal direction of the ski. The lever is locked in a stand-by and a locking position by engaging ratchet arrangements. It is spring-loaded, so that when the boot is removed from the ski, the lever pivots from stand-by into locking position. Insertion of the ski boot into the binding actuates a control element, which in turn actuates the ratchet arrangement for stand-by. The brake lever may be displaced by the control element, axially against spring pressure to a limited degree. The lever is positioned in the ski outside the boot area and the control element consists of a U-shaped wire clip.

Title: Automatic dishwasher system with continuously operated wash programs - has slow start of circulating pumps at each fresh loading to prevent pressure build-up
Inventor: HUETTEMANN WILFRIED DIPL ING
IPC: A47L15/42
Filed: 1976-10-29
Abstract: The dish-washing process for more particularly industrial dishwashers includes an additional step. After the load has been changed and at the beginning of a new washing cycle the circulating pump is activated by an electric smooth-start connection for the pump motor. This means that when starting up, the circulating pump can only develop a low output so that the atmospheric air which has entered the machine is heated up slowly so that there is no sudden build-up of pressure. After the fresh water has been supplied at the beginning of the new wash program the pump motor is momentarily connected to full voltage UN which is necessary to overcome the inertia of the pump. The voltage of the motor is then lowered to the starting value UA where the motor runs for a certain time t1 at low speed. After the high-speed time t2 it then reaches its nominal voltage UN.

Title: Current switching thyristor circuit - has series resistor shunted by capacitor connected to gate to facilitate switching=off
Inventor: HORBACH KURT
IPC: H03K17/73
Filed: 1977-02-14
Abstract: A positive potential is applied to the thyristor gate for its ignition, and after tripping a negative potential is applied to switch it off. A series resistor (11) with a parallel capacitor (12) is connected to the thyristor (5) gate (6) to make it suitable for operation in a DC system. The resistor resistance (R) and capacitor capacitance (C) are such that the R-C time constant is large enough to make the negative pulse peak appearing at the thyristor gate long enough to extinguish the thyristor (5). This peak appears when the thyristor is switched off at the resistor (11) terminal away from thyristor (5) when this point is connected to a more negative potential.

Title: Dry absorption centrifugal reactor for flue gases - with vortex chamber and guide vanes
Inventor: WINTERS HEINRICH
IPC: B01D53/18
Filed: 1977-09-02
Abstract: A centrifugal reactor for the dry absorption of toxic gases and the sepn. of contaminants, e.g. for the dry removal of SO2 from the emissions of coal fired power stations, has above the tangential inflow a vortex chamber.

Title: Rocket with pay load parachute and ejector - has retarder for pay load causing parachute to separate before opening
Inventor: SCHOEFFL RAINER ING GRAD
IPC: F42B12/62
Filed: 1977-12-16
Abstract: A projectile, esp. a rocket or shell, comprises a tubular casing, a pay load to the ejected from the casing an a folded parachute designed to open after separation of the pay load from the projectile. The ejection force is applied to the pay load at the opposite end to that at which the parachute is located. The tubular casing and the pay load are connected together by a folded, rolled up or similarly compressed connecting element; as the pay load separates from the casing, this element is extended until it finally exerts a retarding force on the pay load. Pref. the connecting element eventually is disconnected from the load and/or from the casing, more specifically when a specific force is reached causing it to rupture. By suddenly retarding the pay load after separation, the effect of the connecting element is to cause the parachute to continue ahead so that it is free to open without being obstructed by the payload.

Title: Salt meat massaging drum - closes injured tissue pores by gentle motion along drum with flights
Inventor: BACHERT ARTHUR
IPC: A23B4/02
Filed: 1978-04-06
Abstract: A machine to close the pores of salt meat injected with brine by massage, consists of a revolving drum inside a brine vat, with a loading and unloading opening at the ends. Inclined flights move the meat pieces along the drum as it revolves half immersed in brine. This requires no chemical additives to the injected brine to close the pores of tissue injured by the syringes and the high pressure brine passages in the meat. It activates the protein of the meat to close the torn fibres instead. A continuous mass prodn. is now possible. A drum rests with two toothed rims on pinions, attached to a drive shaft on pedestal bearings at the bottom of a brine vat. The drum has a charging and a discharging opening. Several flights are arranged, with a hinged bottom end and a top end which is adjustable in height by adjusting screws.
