Abstract: A medical syringe has a needle shoot back mechanism which can be triggered to shoot the used needle back into the safety of the syringe body and is of a special design to allow the needle to be replaced without affecting the efficiency of the shoot back mechanism. A rotatable cover member is also available which is relatively large and which can be more easily gripped and turned to remove the needle from the syringe.

Abstract: Disclosed is a metal-ceramic substrate made up of at least one ceramic layer which is provided with metallizations on both faces. In order to obtain a partial discharge resistance of less than 10 pC at a predefined measuring voltage, the thickness of the ceramic layer amounts to about one sixth of the measuring voltage.

Abstract: The invention relates to a novel device made up of a heat source that is formed by at least one electrical or electronic component or is provided with such a component, a heat sink, and an intermediate layer which is located between the heat source and the heat sink and is made of a thermally conducting material. The thermally conducting material is made up of an organic matrix with incorporated nanofibers.

Abstract: The fluid control device is attached to tubes carrying irrigation solution to form the system. The control device splits the flow through a fiber optic scope and a fluid control unit. The fluid control unit controls rate of flow and direction. The flow of fluid into the joint, out of the joint, or no flow is easily controlled by the operator. The device also allows more than one inflow, useful when using suction or suction shaving devices. The increased flow prevents collapse of a joint space and maintains clear visualization. The fluid flow relies on gravity by having a fluid reservoir positioned at a high point in the system.

Abstract: A marking template comprising a planar body portion having a central aperture, and a plurality of sets of apertures in the body portion, each set of apertures located a predetermined distance from the central aperture which enable rectangular patterns to be marked on a workpiece.

Abstract: A door stay having a first part adapted to be supported by door handle on one side of the door, a second part adapted to be supported by the door handle on the other side of the door, and an intermediate part that is adapted to extend over the edge of the door to prevent the latch tongue from engaging with the keeper.

Abstract: A drive apparatus for a vehicle, the apparatus comprising a hydraulic pump, two control valve assemblies, and two pairs of hydraulic drive assemblies. The control valve assemblies are hydraulically connected in parallel, and in an operational condition hydraulic fluid is pumped through the control valve assemblies by the pump to drive the hydraulic drive assemblies, and wherein each control valve assembly proportionately distributes hydraulic fluid to a respective pair of the hydraulic drive assemblies in response to the hydraulic loads of the respective hydraulic drive assemblies of the respective pairs of hydraulic drive assemblies.

Abstract: A computer-implemented method is provided, which includes receiving a plurality of first search queries, each of which comprises one or more first query terms. At least one association graph is constructed that includes at least a portion of the first query terms as vertices. A second search query is received from a user, which comprises a plurality of second query terms. One or more suggested replacement terms for one or more of the second query terms are identified, using the at least one association graph. The suggested replacement terms are presented to the user. Responsively to a selection of one of the suggested replacement terms by the user, the selected suggested replacement term is substituted for the corresponding one of the second query terms, to generate a refined search query. Search results are presented to the user responsively to the refined search query. Other embodiments are also described.

Abstract: A method for testing poles (1) including the steps of applying a first load to a pole (1), measuring the movement of the pole (1), at least partially de-loading the pole (1) to a second load, measuring the movement of the pole (1), and using the change in the movement measurements under the respective loads to calculate the pole (1) stiffness.

Abstract: A method for displaying information includes identifying computer-readable service code at a service site, which code, when read by a client computer via a network, causes the computer to display at least one service page containing service information. At least a portion of the service code is selected for inclusion in a service component containing at least a portion of the service information that corresponds to the selected code. A pointer is generated, indicating a location at which the service component is accessible, for inclusion of the pointer in host code accessible to the client computer from a host site, which is separate from the service site and is accessible via the network, the host code, when read by the client computer, causing the computer to display a host page containing host information. An invocation of the pointer by the client computer is received at the location when the client computer accesses the host page.

Abstract: An engine after-cooling system (10) comprises an after-cooler (11) for cooling compressed air which is output from a compressor for combustion by an internal-combustion engine, a heat exchanger (19) for cooling a coolant which is output from the after-cooler (11), a pump (21) for continuously pumping the coolant through the system (10), an outlet air temperature sensor (27) for sensing the temperature of the compressed air after being cooled by the after-cooler (11), a coolant temperature sensor (17) for sensing the temperature of the coolant output from the after-cooler (11), and a controller (26) for controlling the flow-rate of coolant through the system (10) in response to the sensed air and coolant temperatures.

Abstract: A device used in conjunction with a grave marker or headstone for illuminating a grave site during the night. An enclosure unit is directly affixed to the grave marker or provided in a stand alone unit associated with the grave marker. The enclosure also includes audio material, such as an obituary which can be played by depressing or engaging a switch associated with the enclosure. Both the illumination device as well as the audio material are powered by a rechargeable battery connected to a solar panel provided directly on the enclosure.

Abstract: A light switch is disclosed to turn on or off the light signal in a light channel by means of the response of piezoelectric material to the electric field of light in the light channel. The LIGHT TRIGGERED LIGHT SWITCH is a light switch that is actuated by light of sufficient power. Light of different frequencies may travel in a light channel together without hindering each other, as long as the channel is the right size for both frequencies of light. The light that actuates the switch may be a different frequency than the light signal that is switched on or off. Fiber optic communication channels are among the channels that these switches may be used for.
