Title: System for detecting human presence in hazardous situations
Inventor: GHOSH KALYAN
IPC: G08B13/26
Filed: 1993-05-03
Granted: 2001-06-12
Abstract: The disclosure relates to a system for the detection of human presence in hazardous situations near moving machinery; appropriately shaped electrodes are placed in an area to be safeguarded and a radio-frequency signal of appropriate frequency and voltage is applied on the electrodes creating an alternating electric field around them. A bridge circuit is used to measure the capacitive impedance created by the electrodes and a dissipation factor is calculated from the real and imaginary parts of the impedance. If a foreign object is introduced into the electric field, the characteristics of the dielectric are modified creating a change of the value of the dissipation factor. The dissipation of energy in the high frequency region is much greater if this foreign object is a biological tissue as compared to other types of materials, such as conductors or insulators. Thus, the system detects human presence by noting the increase of the dissipation factor above a threshold value, and the movement of the appropriate machine part can then be stopped, thereby eliminating the danger of injury to the person.

Granted: 1999-04-27
Abstract: A crane and lift apparatus for controlling the lifting and lowering of large cargo containers.  A trolley assembly includes a hoist drum from which is suspended a system of cable or rope reevings connected to material securing assembly.  The apparatus is effective to unload containers stacked one above another from one location to an alternate location,  The system of cable reevings permits the raising and lowering of containers in planes defined by X, Y, and Z axes.  The cables are deployed from the hoist drum on the trolley assembly to sheaves disposed at the four corners of the material securing assembly and then returned to anchor assemblies secured to an undercarriage of the trolley assembly.  The sheaves are selectively angled and located in headblock assemblies positioned on the material securing assembly.  A system of brakes controls movement of the cables through the sheaves.  By selectively combining the angling of the sheaves with selective application of the sheave brakes, it is possible to resolve moment forces acting at each corner of a container so as to abosrb the constantly changing inertial. movements that occur when the container is raised, lowered or moved horizontally.  As a result, the apparatus is effective to dampen or retard the container from swaying, rolling, or pitching, from pendulous movement; and can thereby control the deployment of the container within precise vertical, horizontal, or skewed planes of orientation.

Title: Injection molding nozzle
Inventor: KRUMMENACHER JOSEF
IPC: B29C45/28
Filed: 1994-08-12
Granted: 2001-04-24
Abstract: The injection nozzle comprises a thin-walled centering bushing inserted between the tip insert and the mold insert. The centering bushing engages a shoulder of the mold insert and thus achieves a mutual centering and sealing of the tip insert and the mold insert. This avoids the inflow of molding material into the cavity between the tip insert and the mold insert which would impair or delay the changing of colors of the material, and the injection needle is effectively centered so that a cylindrical tip portion can close a very short cylindrical portion of a gate bore. The heat transfer between the heated nozzle parts and the mold insert is nevertheless maintained at a low level since the mutual centering is obtained by narrow contact sites.

Title: Addressing ferroelectric liquid crystal displays
Inventor: HUGHES JONATHAN RENNIE
IPC: G09G3/36
Filed: 1994-04-08
Granted: 2004-03-30
Abstract: The invention concerns a surface stabilised ferroelectric liquid crystal (SSFLC) display devices. Displays are formed by cells containing a thin layer, e.g. 2 µm thick, of smectic liquid crystal material. The cell walls are surface treated and carry e.g. row and column electrodes forming an x,y matrix of addressable display elements or pixels.  These devices can show bistability and switch between their two stable state on application of a dc pulse of appropriate polarity, amplitude and width. In this invention the device is addressed by first preconditioning the liquid crystal material at each pixel by applying one of two different levels of ac bias, thereby changing the switching characteristics of the material, and second by switching with application of a switching pulse. This results in pixels that have received the first of the ac bias levels switching whilst the other pixels do not switch.  The two levels of ac bias may be applied e.g. by a combination of bipolar strobe pulses and two bipolar data waveforms applied in a multiplex addressing manner to the row and column electrodes. The subsequent switching pulse may be shared between row and column electrodes to give a resultant pulse of appropriate polarity, amplitude and width.

Abstract: A nuclear magnetic resonance (NMR) logging technique reveals the volume of hydrocarbons in an earth formation. The differences in viscosity among gas, oil and water are used to distinguish among these three fluids. During NMR logging, a parameter of a sequence of magnetic field pulses is altered, causing echo signal strengths to vary due to the diffusion of the fluids in the formation. The volume of hydrocarbons in the formation is determined from detected spin echo strengths. The invention applies to wireline NMR logging and NMR logging-while-drilling techniques.
