Patent DE-2965121-D1 (DE)
Title: Apparatus for dynamically cooling and pumping molten thermoplastic material
Inventor: WINSTEAD THOMAS W
IPC: B29C48/92
Filed: 1979-12-21
Granted: 1983-05-05
Abstract: A dynamic cooler apparatus is provided for dynamically cooling molten plastic extrudate while pumping metered amounts of that extrudate to an extrusion die or the like. The dynamic cooler apparatus utilizes bi-helical gears in a gear pump configuration in a housing in which a heat exchange medium is circulated. The heat exchange medium is also circulated internally of the gears so that the gear teeth and the housing act to cool discrete volumes of extrudate from four sides defined by the gear teeth and the internal surface of the housing. The bi-helical gears are driven to minimize loading between the teeth thereof and to permit the teeth to be as small as practical to present more cooling surface for a given cross-section of extrudate and optimize the heat transfer capability of the dynamic cooler apparatus. Provision is also made to use the molten extrudate as a lubricant for the shafts and bearings of the bi-helical gears.

Title: Watch with a perpetual date mechanism
Inventor: GROOTHUIS MICHEL
IPC: G04B27/00
Filed: 1981-10-29
Granted: 1985-03-28
Abstract: The mechanism comprises a date-disc (8) actuated at midnight by a lever (1) supporting a rotary part (3) with catches (3a) gearing with the wheel (4) of 24 h. The mechanism is so designed that each transition from a date to the next is effected in less than one hour so that the calendar remains still in synchronism with the hours hand, even in the case of the changing of the indication of time-zones. The disc comprises pins (14) controlling at the end of each month through a star-wheel (13) the rotation of a first (17) and a second (20) cam. The cams bear finger-pieces (17a,17b,21) the ones (17a,17b) of the first cam having variable widths according to the different lengths of the months forming bankings for a catch (9) of the lever (1) for hindering the return motion of this lever thus prolonging the duration of the gearing of the rotary part (3) with the disc (8). At the end of February of the normal years a finger-piece (17b) of the first cam (17) juxtaposes itself with a finger-piece (21) of the second cam (20) for causing the transition between the 28th of February and the 1st of March. This finger-piece (21) is missing in the leap years. The mechanism operates in the two directions of rotation of the wheel of 24 h.

Abstract: The tube has a peg-shaped neck extension (3) at its upper end, which contains a predetermined breaking point (4). The neck extension (3) is generally positioned under the removable protective cap (7). A short socket (9) is formed on the upper side of the cap (7) in an axial direction, the interior diameter of which is slightly greater than the diameter of the neck extension (3). The inner surface of this socket (9) and the outer surface of the neck extension (3) are provided with corresponding notch flanges (5) or notch grooves (10), such that the cap (7) and the neck extension (3) are non-positively connected to each other when rotated about the longitudinal axis, when the cap (7) with the socket (9) is positioned on the peg-shaped neck extension (3). If the cap (7) is rotated in this position about the longitudinal axis with slight pressure simultaneously exerted then the peg-shaped neck extension (3) is sheared off at the predetermined breaking point (4) and the tube is thereby opened. The cap (7) thus acts as protective cap on the one hand and as a tool for opening the tube on the other hand.
