Variable pitch thread configuration תבריג בעל פסיעה משתנה

An apparatus for providing a variable pitch thread includes a hollow cylindrical element configured to provide a plurality of parallel, radially projecting ridges extending circumferentially around the cylindrical element and spaced apart with a given step as measured parallel to a central axis of the cylindrical element. The cylindrical element also featuring a slit extending substantially...

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...

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...

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...

Rear-door for vehicles דלת אחורית לכלי רכב

A rear door assembly for a vehicle includes a rear door surround and a door connected thereto by a mechanical linkage. The mechanical linkage is configured to selectively either retain the door in a closed state relative to the door surround, or to permit opening of the door in a pivoting motion about at least two, and preferably three, hinge axes selected from: a vertical axis adjacent to the...

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...

Cylinder lock with rotatable pins מנעול צילינדר עם פינים מסתובבים

A cylinder lock has a plug deployed within a bore in a cylinder housing. The plug defines a keyway which communicates with a number of pin channels. Disposed within the channels are a number of pins which are displaceable along, and rotatable about, their axis. Each pin has an engagement end, proximal to the keyway, formed with at least two engagement features projecting parallel to, but displaced...

"התורה על רגל אחת"

אגדה ידועה במסורת היהודית (תלמוד בבלי, מסכת שבת) מספרת על גוי שהגיע לשמאי וביקש ממנו שיגייר אותו על מנת שילמדו את כל התורה על רגל אחת,אך שמאי גער בו והוציאו בנזיפה. הגוי הגיע באותה בקשה להלל, וזה ענה לו: "מה ששנוא עליך אל תעשה לחבריך, והשאר -  רק פירוש." ושלחו ללמוד. ניתן לראות כי הלל הצליח בעצם לתמצת את כל התורה למשפט אחד. יכולת זו הינה חשובה ביותר. ברמה השיווקית היכולת לתמצת רעיונו של...
