Title: Magnetic resonance imaging RF coil for imaging human head - has two null inclination solenoid coils on transparent substrate mounted in helmet
Inventor: DERBY KEVIN A
IPC: G01R33/36
Filed: 1993-09-01
Abstract: The quadrature MRI RF coil arrangement has a helmet shape to match the shape of the human head (102). A pair of null inclination solenoid coils (L10,L12) is mounted inside the helmet structure. One solenoid coil's (L12) longitudinal axis is parallel to a line from the apex of the helmet to the neck of a head inside the helmet. The longitudinal axis of the other solenoid coil (L10) is essentially parallel to a line from one side of the head to the other. Each coil contains printed conductors on a transparent substrate. USE/ADVANTAGE - For transferring quadrature MRI RF signals used to represent spatial contents of human head. Sensitivity to coupling effects is reduced and coil design simplified.

Filed: 1993-10-26
Abstract: The invention relates to a control device for the transport of workpieces in a machine of printing technology in which, with the aid of edge detectors, signals are obtained which influence the transport process. Workpieces should be understood to consist of thin materials which are fed to a printing machine, for example as sheets individually or in overlapped form, or which are transported as folded products in a stream from a folding apparatus. It is the object of the invention to develop an edge detector which is constructed using simple means and which is suitable for the detection of workpieces made of very different materials. The invention consists in providing, in the transport path of the workpieces, an electrification arrangement (5, 6) which is followed in the transport direction by an electrostatic measuring arrangement (7, 8, 9). The electrification arrangement (5, 6) applies electrical charges to the surface of the workpieces. The electrostatic measuring arrangement (7, 8, 9) detects the electric field which changes when the workpieces (3) are moved relative to the electrostatic measuring arrangement (7, 8, 9). According to the properties of an electric field, the greatest field strength changes occur at the edges of the workpieces (3), said changes being used as an indicator of the passage of the respective workpiece edge at the electrostatic measuring arrangement (7, 8, 9). The invention is ... in the transport of workpieces in a ... of printing technology... Original abstract incomplete. <IMAGE>

Title: Conductor track plug-in board for IC sockets
Inventor: BLUMENBERG DIRK DR
IPC: H05K3/36
Filed: 1994-07-14
Abstract: If, in the case of existing electronic circuits of so-called printed conductor tracks or printed circuit boards having a conductive perforated-strip grid, it is desired to modify the circuit of individual assemblies or functional units within a more complex overall circuit, or to insert such a circuit newly, in order, for example, to experiment, the conductor tracks frequently have to be modified as a makeshift measure and so much of the circuit has to be resoldered that complete reconstruction of the entire circuit is frequently made necessary just for visual reasons. Frequently, it is even totally impossible to carry out modifications within the overall circuit, so that time-consuming and expensive circuit redesign is unavoidable in any case.

Patent DE-4444170-A1 (DE)
Inventor: TENG ALEX C
IPC: B29C45/26
Filed: 1994-12-12
Abstract: Valve gated injection molding apparatus with a spring mounted on a central pin adjacent the head of a valve member in a spring chamber in each of the pistons. The spring is compressed between the base of the pin and the cap of the piston to preload it. When the valve member and piston are driven forwardly to the closed position, the head of the valve member retracts somewhat into the spring chamber against the force applied forwardly against the head of the valve member by the spring. This cushions the impact of the front end of the valve member in the gate and provides for tight seating of the front end of the valve member in the gate without requiring all of the components to be made to precise tolerances with exact allowance for thermal expansion. The spring is a number of selected disc springs stacked in sets facing in opposite directions, from which the force applied to the head of the valve member is predetermined.
