Patent DE-2965442-D1 (DE)
Title: Gas flow apparatus, especially for a ventilator for large buildings
Inventor: MARTIN STANLEY IRVIN
IPC: F24F7/06
Filed: 1979-09-10
Granted: 1983-07-07
Abstract: A ventilator for barns and the like, having a generally rectangular housing (12), containing duct work, adapted to fit through a wall or roof of the building. The housing (12) has an inside and an outside end and at its inside end, the housing (12) has an intake fan (28) for drawing air inwardly, and an outlet fan (30) for drawing air from the interior of the building. At its outside end, the housing comprises a transfer chamber (36) with air outlet openings (48) on one side of said chamber and air intake openings (46) on the other side of said chamber. A two part damper (50a, b) is movably mounted within the transfer chamber (36), the two parts being swingable towards and away from one another. A linkage arrangement (60a, b) interconnects the two parts of the damper so that they move in unison in opposite directions in response to operation of a drive motor (64). This enables the ventilator to operate in two modes, a first mode in which it draws in fresh air and expels stale air simultaneously and a second mode in which it recirculates the air within the building, according to the settings of the damper parts. In intermediate settings both modes of ventilation can take place at the same time. The two fans (28, 30) and associated motors are mounted on a mounting frame (22) which is hingedly connected to the housing (12) to facilitate servicing of the ventilator.

Title: Improved disposable diaper having refastenable tape system
Inventor: SARGE III HENRY DAVID
IPC: A61F13/49
Filed: 1979-09-06
Granted: 1984-05-30
Abstract: An improved disposable diaper of the type having a relatively high elongation to tensile force property, an absorbent pad, and tape-tab fasteners coated with a peelable adhesive. The backsheet is reinforced by coating the mother's bond region thereof with a material having high tensile strength and a low elongation to tensile force property relative to the backsheet material. The coating may be continuous or patterned and may be disposed on either the outwardly facing surface or the inwardly facing surface of the mother's bond region of the backsheet. When applied to the inwardly facing surface, the coating material may be adhesive material and may secure the backsheet to the pad assembly of the diaper. The reinforcement of the backsheet improves the resistance of the backsheet to stretching and tearing when subjected to tensile forces during fastening and wearing, and to peeling forces when the tape-tab fasteners are being peeled open. Thus, the fasteners are refastenable.

Filed: 1983-12-28
Granted: 1988-04-07
Abstract: The rank of a defective cell in a level-sensitive scan-design chain within the functional element (13) is found by a static (FLUSH mode) test, applying a square wave from a 20 kHz generator (15). This also triggers a digital storage oscilloscope (11) connected to a computer (12) by a IEEE 488 interface bus. The power supply (14) is connected via a small series resistor (R) with a large shunt capacitor (C) for noise redn. Master flip-flop clock inputs (A,C) are set at 1 and zero respectively, and a slave flip-flop clock input (B) at 1. Current variations are displayed as the input datum is propagated along the chain. In this signature a period of constant current indicates that the last cell to be loaded with the input datum is faulty.

Abstract: A reversible reel assembly including two rotatable reels for successively, continuously winding rolled strip. The two reels are mounted on a rotatable head plate and are rotatably driven independently from each other. In order to supply the positioning drives of the reels with drive media, rotatable media supplies which are trouble-prone and expensive are required. In order to provide a reversible reel assembly without trouble-prone media supplies, a reel is suggested in which the reel drums are continuously spread-apart by means of the force of a spring and the positioning drives are arranged stationary independently from the reels, so that the reels can be moved into the positioning drives in certain positions and the movement of the segments between a position of rest and a spread-apart position can be effected in these positions.

IPC: A61K9/50
Filed: 1986-10-06
Granted: 1990-03-15
Abstract: The invention relates to a completely novel type of micro-capsules, viz. such capsules where an encapsulated hydrophobic or lipophilic substance is surrounded by polar solid crystals of polar lipids which expose their hydrophilic face outwards and their hydrophobic face turned inwards towards the hydrophobic or lipophilic substance. These micro-capsules can be utilized to encapsulate for instance tacky substances or substances to be protected against oxidation or influence from light. Moreover, an especially interesting use according to the invention is the use of said micro-capsules in an ointment base, where the active ingredient is well protected within said capsules up to the use but which at the application on the skin directly comes into contact with the skin surface as a consequence of the crystalline structure of the shell. Furthermore, the invention relates to a special micro-capsule composition in the form of a dispersion of said micro-capsules in water or a polar liquid, where the crystals constitute 5-50 percent by weight and water or the polar liquid 50-95 percent by weight. Moreover, the invention relates to a process for the preparation of said micro-capsules, wherein a mixture of said polar lipid with water or polar liquid is formed, the mixture is heated above the transition temperature of the lipid and the mixture is then cooled to the desired temperature so as to obtain crystallization, the hydrophobic or lipophilic substance being added before or during the liposomic phase. Finally, the invention relates to a crystal dispersion of the polar lipid in a polar liquid, such as glycerol, ethylene- or propylene glycol.
