Abstract: A switching assembly having an on switch with a separate off release actuator. The switching assembly has a switch which has both an on position and an off position. Connected on the switch is an on button which has both a released position and a depressed position. The moving of the on button into the depressed position causes the switch to toggle into the on position. Also connected to the switch is an actuator rod which provides for the locking and releasing of the switch from the on position. The actuator rod is connected to an off button which has both a depressed position and a released position. Moving the off button into the depressed position causes the switch to toggle into the off position. Furthermore, a spring is connected to the actuator rod for maintaining the on switch in the on position until the actuator is forced to release the on switch from the on position.

The shield is electrically connected to the stationary contact terminal. The movable contact ring and coaxial shield at the upstream end of the nozzle define a well shielded open gap when the interrupter gap opens.

Abstract: Double pancake coils include a pair of pancake coils of different outer dimensions, and are wound from the same continuous length of superconducting wire. The double pancake coils are coaxially positioned and electrically interconnected along a longitudinal axis to provide a multi-coil superconducting magnetic coil assembly. Each of the double pancakes has at least one of its pancake coils electrically connected to at least another pancake coil of an adjacent double pancake coil having substantially the same outer dimension. The electrical connections between adjacent pancake coils are provided with relatively straight or "unbent" segments of superconducting wire even though the outer dimension profile of the superconducting magnetic coil assembly along its longitudinal axis varies.

Abstract: A weight-sensing member is made from material with good toughness and elastic deformability characteristics and has a top end, a bottom end and a broadened portion located between and integral with the first and second ends. The broadened portion has a pair of opposed peripheries between the top and bottom ends, a horizontally extending through-hole, and a pair of S-shaped slots formed symmetrically on both sides of the through-hole. Each of the slots begins with an open end at a respective one of the opposed peripheries adjacent to a corresponding one of the top and bottom ends and terminates with a closed end near the through-hole. Each S-shaped slot divides partially the weight-sensing member into two separated parts, namely a higher part near the top end and a lower part near the bottom end. The lower part has a higher portion with a protrusion that extends into an opening that is formed in the higher part.

The compression space is connected to a low-pressure space via a pressure relief valve and a refill valve.

Abstract: A safety switch assembly for fitting to a safety enclosure. The switch includes a rotatable cam which operates electrical contacts. An actuator is insertable into the switch housing through either of two apertures to engage locking members. The locking members move in a rectilinear direction perpendicular to the cam axis away from the actuator and our of locking engagement with the cam. Ears on the actuator then engage in pockets in the cam and rotate the cam which causes movement of the electrical contacts to the ON position. Each locking member comprises a pair of locking components one of which is slidable on the other and both of which define elongate slots through which a cam shaft extends. The slots are inclined such that when the actuator pushes either one of the components away from a first aperture the other component is forced to move away from the other aperture.

Abstract: An interlock switch for electrically coupling opposing surfaces of a circuit card assembly, wherein each of the surfaces includes a contact pattern defining circuit and switch functions. The interlock switch comprises a pair of contacts which engage the contact patterns on the circuit card assembly to electrically couple the circuits located on the oppositely facing surfaces thereof and a switch body for housing the contacts. The switch body includes a slot for solder-free coupling the switch to an edge of the circuit card assembly. The slot enables the switch to selectively reciprocate among three switch positions on the edge of the circuit card assembly to provide either an open circuit or a closed circuit on the circuit card assembly in any one of three switch positions for each contact. A spring is housed within the switch body for biasing the switch from one of the three positions making it a momentary position.

Abstract: A method of determining a load measurement value in dynamic weighing of an object passing over a weighing platform supported by load-sensing means generating a load-dependent weighing signal (S) which rises from a basic level to a peak level, to subsequently fall to the basic level. An at least approximative signal peak value (S.sub.peak) is determined as representing the weighed load. The weighing signal is integrated at least during a time interval (t.sub.1 -t.sub.5) about the point where the signal peak value is determined in order to produce a summation result, the time interval being recorded as a measurement time factor (M). Further, a form factor (F) for the weighing signal is calculated in the form of the ratio of the summation result, i.e., the integrated area under the weighing signal (S) for the time interval (t.sub.1 -t.sub.5), to a corresponding rectangular area that would be obtained in static weighing, i.e., the product of a peak value and the above time interval.

Abstract: A method and system for weighing an object as it is carried on a conveyor past an x-ray source. X-rays from the x-ray source pass through the object, are attenuated in proportion to the mass of the object through which they pass, and impinge upon an x-ray detector array. X-ray detector array includes a layer of scintillating material that produces light in response to the intensity of the x-rays and a plurality of photodiodes to detect the light. The intensity of the x-rays received at the x-ray detector array is indicated by signals produced by the photodiodes, which are periodically scanned by a processor. The photodiode signals are each converted to a value representing the average areal density for a volume element extending above the photodiode into the object. Using the average areal density for each volume element and the size of each volume element, the processor determines the mass of the volume element.

Abstract: A shock sensor capable of detecting a shock in a number of directions includes a reed switch, which is fixed inside a body and has a reed contact part with is magnetically changed from a first to a second state by way of a magnet, which is fixed inside the body at a specified distance from the reed switch. A shield member, having a sufficiently large area, prevents the magnetic force of the magnet from affecting the reed contact part when the shield member is in its regular position. A resilient member, in a normal state, keeps the shield member at its regular position between the reed contact part and the magnet, at which the reed contact part is kept in the first state. When a shock is applied to the shock sensor, the resilient member allows the shield member to move to a position where the reed contact part changes over to the second state.In a second embodiment, the magnet is movably held in the main casing at a specified distance from the reed switch.

A shading ring is connected with the core to provide magnetic flux which is out of phase with magnetic flux from the core. The shading ring includes a base formed a first metal and a layer of a second metal clad to the base. The first metal forming the base work hardens and has a greater resistance to fatigue failure induced by vibration than the second metal of the layer which is clad to the base.
