Title: Method of examining samples using nuclear magnetic resonance
Inventor: HINSHAW WALDO STEPHEN
IPC: A61B5/055
Filed: 1982-01-26
Abstract: Spatially discriminated information is obtained by appropriately processing data which are generated with the aid of a set of pulsed nuclear magnetic resonance operations carried out by means of a magnetic field having a linear gradient whose magnitude varies for each operation. In order to obtain a two-dimensional image of the spin density distribution, coil sets (5 and 6) are used to generate magnetic field components which yield X- and Y-gradients, the magnitude of the former being varied in steps while that of the latter remains unaltered. For each value of the X-gradient, the sample (1) is irradiated with pulsed high-frequency energy, the resultant nuclear magnetic resonance signals being detected with the aid of phase-sensitive detectors (19 and 20), whose output signals are regularly sampled by analog/digital converters (25 and 26). In processing the complete sampled data using a computer (12), both a Fourier transformation with respect to the magnitude of the X-gradient and a Fourier transformation with respect to time are carried out. If there is a requirement to obtain cross-sectional images, a third set of coils (7) is used in order to generate a component which yields an alternating Z-gradient and the irradiation is carried out with the aid of a train of pulses. <IMAGE>

Title: Underground tank for receiving and distributing liquids, in particular for water supply
Inventor: SCHULZ SIEGFRIED
IPC: E03B11/14
Filed: 1982-01-28
Abstract: The invention relates to an underground tank (1), in particular for water supply, having a water-storage tank (2) and a valve chamber (3), designed as a separate structural unit, for receiving a hydraulic installation. The water-storage tank (2) is composed of large, horizontal, prefabricated pipes (5) and is designed, between the supply and discharge (20 and 28, respectively) as a closed, tubular and flow-through body. Supply to the water-storage tank is effected tangentially with respect to the base and approximately perpendicularly to the longitudinal axis of the water-storage tank or the water chamber. Discharge from the water-storage tank is effected essentially parallel to the longitudinal axis of said storage tank, likewise at the bottom of the pipe tank. In this way, water flows through the water-storage tank (2) in a helical manner, with the result that excellent thorough mixing of the stored water is achieved, without any "dead" or insufficiently flowed-through areas occurring within the storage tank. <IMAGE>

Title: Device for applying retentions to a dental cast
Inventor: RUDY GERT
IPC: A61C13/12
Filed: 1982-02-10
Abstract: A device for applying retentions to a dental cast comprises a handle which is connected via a plug-in opening to a tubular receptacle serving to receive wax beads, so-called retentions. The handle has a duct extending over the entire length of the handle including a connection piece for a vacuum line of a vacuum pump and is aligned with the receptacle duct. A tapered end of the receptacle is provided with a duct section whose internal width is smaller than the diameter of the retentions. For receiving a retention the device is held by the handle and guided to the retention with its receptacle with the vacuum pump switched on until the retention is sucked in by the receptacle as a result of the suction effect. The retention is then pressed, by means of the device, with light pressure onto an adhesive layer of the cast. The receptacle is lifted from the retention by opening an air inlet at the handle, which causes the suction effect to diminish.

Title: Preheating device for oil and use of the preheating device in a heating installation
Inventor: KLINGER UWE
IPC: F23K5/20
Filed: 1982-02-23
Abstract: The invention relates to a preheating device for oil, in particular for heating the fuel oil to be supplied to the burner of a heating boiler. The preheating device consists essentially of an inner heating pipe (1), an oil chamber (2) surrounding the heating pipe (1) and an additional heating device (3). The heating pipe (1) is preferably inserted into the forward run line of the heating circuit of a heating installation. The heating device (3) is electrically operated, as a result of which the fuel oil situated in the oil chamber (2) can be heated to a favourable temperature already before the heating installation is set in operation. The heated fuel oil can burn better, as a result of which a greater degree of efficiency is achieved for the heating installation. <IMAGE>

Abstract: The invention relates to a pump (1) which can be used preferably as a water raising device for surface waters. The pump (1) comprises a pump pipe (2), the bottom end of which is immersed in a liquid (11). A pump shaft (3) with rotor blades (4) (ships screws) arranged at intervals on it is inserted in the roughly vertical pump pipe (2). The pump shaft (3) can be rotated by a drive unit (5).

Title: Elastic bearing having a stop element
Inventor: BUERGLER KARL-HEINZ
IPC: F16F1/373
Filed: 1983-05-07
Abstract: Elastic bearings which are installed for example in motor vehicles and have a flexible stop element are frequently subjected to the influence of dirt and water spray which can lead to a change in the bearing setting and to corrosion. In order to prevent the ingress of dirt and water spray into the bearing interior, it is proposed that a sealing collar, which is constructed integrally with the stop element, extend as far as the mating stop of the stop element and rest thereon with its free edge, subject to pretensioning, so that the bearing interior is hermetically sealed to the exterior.

Title: Heating device for ironing steam
Inventor: STEIN GUENTHER V
IPC: D06F75/12
Filed: 1984-01-27
Abstract: What is described is a heating device for the ironing steam of steam irons, with a heating system and a labyrinth iron steam-guide system, which heating device, in the simplest design, reliably prevents an overheating of the steam and in which no creep paths for the steam can open within the steam-guide system. The heating device consists of a core and of separating webs which are made in one piece with this core and which are fitted in a recess in a housing body. The part of the housing body surrounding the recess and the core together with the separating webs are produced from materials having coefficients of thermal expansion which differ only slightly from one another. The heating system is arranged outside the recess. In a preferred exemplary embodiment, the core and the separating webs are designed as an exchangeable cartridge and are inserted directly into the steam iron. At the same time, the separating webs are designed as annular flanges flattened on one side, the flattenings of two adjacent separating webs being offset at 180 DEG  relative to one another and thereby, in conjunction with the wall of the recess, forming the labyrinth for the steam.
