Abstract: The invention relates to an arrangement for retro-actively cutting wiper blades, comprising a first guiding element (D) which engages in grooves which are arranged on both sides of the wiper blades, and a second guiding element (L) which is arranged in close proximity to the edge of the lip (M) of the wiper blade which is to be retro-actively cut. A blade (J) is arranged in close proximity to the second guiding element (L). The second guiding element (L) has a fixed width such that the lip (M) of the wiper blade is guided in a smooth-running manner.

Abstract: A pulse hydraulic system is disclosed comprising, in combination a hydraulic sump for supplying the system with hydraulic fluid, one or more hydraulic pumps taking suction on the sump for increasing the pressure of the hydraulic fluid exiting the sump, a pulse generator fed by the discharge from the pump(s) for creating pulsed pressure of the hydraulic fluid output therefrom, an actuator coupled to the pulse generator for doing work, and one or more accumulators coupled between at least one of the pump(s) and the pulse generator, between the pulse generator and the actuator, and between the pulse generator and the sump for storing and supplying pressurized hydraulic fluid to the system. The addition of one or more pulse intensifiers to a pulse hydraulic system increases the overall system efficiency.

Abstract: A chewing gum composition and process whereby the process comprises softening the base between a temperature range of about 40.degree. C. to about 60.degree. C.; admixing softening agents, sweetening agents and flavoring agents; extruding the composition prior to cooling; forming the composition into suitable chewing gum pieces without cooling; and immediately wrapping the pieces with a minimum of protective wrapping without prior conditioning. No moisture or moisture-containing ingredients are used and the chewing gum composition has a final moisture content of up to about 0.3% by weight.

Abstract: Process and apparatus for treating material by applying non-sinusoidal vibrations. In apparatus for separating solids from the liquid phase of a dispersion, non-sinusoidal vibration is applied by vibrating at least a portion of a wall of a receptacle for the dispersion or by a vibrating plate, a pair of vibrating plates or a hollow body in the receptacle. In a roller mill for crushing material one of the rollers is vibrated axially relative to the other. In a juice press a vibrating plate is provided at the bottom of the press cylinder. In a jaw crusher, one of the jaws is vibrated in a direction parallel to the face of the jaw. In a ball mill comprising a cylinder rotating on a horizontal axis, the cylinder is vibrated in an axial direction. Non-sinusoidal vibration is produced by a hydraulic servomotor fed with pulses of hydraulic pressure fluid by a rotary control valve.
