Sabbath elevator מעלית שבת

A drive system provides a displacement mechanism for driving motion of a device using energy stored in an energy accumulator in a non-electric form. A charge/discharge arrangement selectively charges the energy accumulator with energy derived from an energy source while isolated from the displacement mechanism, and the connects the energy accumulator to the displacement mechanism to provide energy...

Wheel with suspension system and centralizing unit with suspension system גלגל בעל מערכת שיכוך פנימית

A wheel with a suspension system being connectable to a vehicle, like a wheel chair, comprises a hub (38) and a rim (34) rotatable about the axle (42) of the hub (38). Between the hub (38) and the rim (34), a number of support members (40) is located. The support members (40) are adapted to retain the distance when stressed up to a threshold value and recoverly alter the distanced when stressed...

Energy absorber and method of absorbing energy מתקן ושיטות לספיגת אנרגיה

An energy absorber has first and second anchorages (18) and is adapted to absorb energy when and only when an applied load along a line of action extending generally through said anchorages exceeds a predetermined limit. The energy absorber comprises at least one leaf (10) extending between the anchorages, the or each leaf having corrugations (16) transverse to said line of action and being...

Methods and devices for reducing trembling מכשירים ושיטות להפחתת רעידות

The present invention is a method and device for reducing trembling of a limb of a human subject. The method comprises suspending a mass from the limb via a suspension configuration. The suspension configuration having an effective spring constant and/or a non-zero coefficient of damping in at least one direction such that the mass is driven to oscillate in the at least one direction out of phase...

Clamping assembly for injection molding apparatus מתקן נעילה למכונות הזרקה

A clamping assembly for an injection molding apparatus includes a first platen attached to a base and a second platen slidingly associated with the base. A number of tiebars are mechanically linked to each of the platens through a number of mechanical linkages. An actuation system associated with the plurality of tiebars and with at least one of the platens is configured to generate movement of...

Pump Apparatus and Methods for Using Same מתקן שאיבה ושיטות יישום

A pump apparatus for transporting at least one fluid, comprising a shaft, wherein the shaft has a longitudinal axis; a motor, wherein the motor is adapted to rotate the shaft about the longitudinal axis; and, a plurality of gerotors, wherein the gerotors are attached to the shaft along the longitudinal axis and wherein the shaft rotation actuates the plurality of gerotors rotation, causing pumping...

Scanning mechanism for high-speed high-resolution scanning מנגנון סריקה ברזולוציה ומהירות גבוהות

A scanning system for use in inspecting or writing on a substrate minimizes vibrations by applying movement-actuating forces directly between a carriage and a countermass which are both free to move along parallel tracks. Forces for decelerating and accelerating the scanning carriage are preferably applied along a minor part of a length of movement of the carriage. The carriage is then isolated...

Hinged and sliding door assembly for vehicles דלת כנף והזזה משולבת לרכב

A hinged and sliding door assembly for vehicles includes a door surround defining an opening, a door configured for mating with the door surround, and a hinge-and-slide mechanism for supporting, and defining movement of, the door relative to the surround. The hinge-and-slide mechanism has an intermediate element connected to the door by a hinge structure which defines an axis of rotation about...
