Title: Nmr measuring method for application to nmr tomography
Inventor: POST HANS DR
IPC: G01R33/48
Filed: 1983-03-05
Granted: 1986-03-20
Abstract: In NMR tomography, the nuclear spins of a selected type present in a selected area of a body are selectively excited by applying first a selection gradient field and exciting thereafter the nuclear spins by a HF signal which initially effects a rotation of the nuclear spins situated in a selected plane by an angle  alpha  of less than 90 DEG , then a rotation of all selected nuclear spins by 90 DEG  and finally again a rotation of the nuclear spins contained in the selected plane by an angle of 90 DEG - alpha . As a result thereof, the nuclear spins contained in the selected area have resumed at the end of this excitation their original orientation determined by a homogeneous magnetic field, while nuclear spins located outside this area lie within a plane extending almost vertically thereto. Thereafter, a measuring gradient field may be switched on without disturbing the orientation of the nuclear spins contained in the selected area. With the measuring gradient field switched on, the nuclear spins are now excited by a 90 DEG  pulse or usual pulse sequences to produce an induction signal. The measuring processes are carried out in pairs, with the selection gradient field applied, using different excitation signals so that the nuclear spins contained in the selected area are alternately oppositely directed which means that the induction signals generated by them are phase-shifted by 180 DEG , whereas the nuclear spins situated outside the selected area are shifted in the same sense so that they supply identical signals, if any.

Title: Door closer
Inventor: TILLMANN HORST
IPC: F16F9/00
Filed: 1984-09-11
Granted: 1989-06-29
Abstract: A door check wherein a housing is affixed to the pivotable panel and a guide rail is affixed to the frame of a door. The housing contains a shaft which is rigidly connected with one end of an arm the other end of which is slidably guided by the rail. The shaft carries a disc cam having two asymmetric sections one of which is tracked by a spring-biased follower surrounding an antifriction bearing and tending to return the panel to its closed position and the other of which is tracked by a roller on the piston of a damper which yieldably opposes the movement of the panel back to its closed position. The configuration of the two cam sections is selected with a view to allow for a reduction of the resistance which the follower offers to opening of the door shortly after the panel leaves its closed position as well as to ensure that the damper can operate independently of the follower and vice versa. The damper has a spring which urges the roller against the cam and whose bias is not more than 50 percent of the bias of one or more springs which urge the follower against the cam.

Abstract: Improved fiber resin matrix prepreg fabrics are disclosed which are comprised of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The discrete second layer is provided with a support comprising a gauze-like, lightweight fibrous mat or carrier of light-weight fibers that preserves the second "interleaf" layer during cure. Cured composites having the continuous interleaf layer intact exhibit high impact strength and resistance to impact damage. In addition, high-performance fiber resin matrix composites are disclosed which are comprised of a first layer comprising reinforcing filaments coated with a thermosetting resin composition and a discrete second layer of a thermoplastic resin. When the composite layers are matched to provide certain minimum strength and elongation properties, composites of unusually high impact strength and resistance to impact damage are achieved which retain their high performance properties over a range of temperatures and environmental exposures.

Abstract: Check valves used in the medical field usually consist of a closure body and a separate spring element. In the case of very small dimensions, problems arise upon assembly and disassembly. A particularly service-friendly and easily manufactured valve (15) can be obtained, if the closure body and spring element form one component. The spring element advantageously consists of a resiliently elastic section (15b), which is arranged between the closure body (15a) and an in contrast stationary end section (15c) and is connected to this. The valve is particularly suitable for installation in the fluid conduit (12) of a dental handpiece and can there be used as a germ-blocking valve. <IMAGE>

Abstract: A process for microfilming and determination and storage of document film position information and evaluation of the data for reproduction of the document from the microfiche. The document specific identification or search data of a document to be filmed is fed into a computer memory, which outputs the memory address location opened in the form of a code to identify the document and reserves additional data storage space under the address. During filming of the document, the position data determined by a coordinate slide of the camera, controlled by a stepping motor on the microfiche, is reproducibly stored in the reserved memory location of the computer under the document specific data. The code associated with the document to be filmed is read by the camera or fed into it and passed to a camera memory. The filming data determined by the camera during filming of the document is correlated with the memory, which contains the identification and search data of the document under the address code. The procedure is carried out by a device for automatic microfilming of documents of different formats and for development of exposed microfiche in a continuous process with a computer controlled combination of certain systems.

Abstract: A machine for the prepn. of ice cream, milk shakes or sorbet consists of a container for the basic mixture, e.g. ice mix for the preparation of ice cream, and a freezing cylinder with a stirring mechanism. To maintain an exact ratio of compressed air to ice mix, a pump for the injection of ice mix in the cylinder is controlled by a valve in the air supply line. This is kept open or closed as a function of the pressure in the cylinder. A pump driven by a motor, is used to pass the ice mix from the container to the freezing cylinder with the stirring/raking mechanism. The motor is controlled by a pressure monitor which also operates the solenoid valve for the compressed air from the compressor and air receiver.
