The inputs of an operational amplifier are connected across a telephone line and bridged by a capacitor. The output of the operational amplifier drives the coil of a relay via an intermediate amplifier. The relay is of the make-before-break type, and is interposed between an audio source, audio speakers, and dummy load resistors. When the voltage across the telephone line indicates an on-hook condition for a telephone, the audio source is connected to the speakers through the relay. When the vol...

A charged particle beam is formed to a relatively larger area beam which is well-contained and has a beam area which relatively uniformly deposits energy over a beam target. Linear optics receive an accelerator beam and output a first beam with a first waist defined by a relatively small size in a first dimension normal to a second dimension. Nonlinear optics, such as an octupole magnet, are located about the first waist and output a second beam having a phase-space distribution which folds the ...

A stake assembly for the support of soccer poles and other tubular structures includes a pair of generally parallel vertical members affixed together and spaced a desired distance apart by an upper lateral member interposed between the vertical members proximate their upper portion, and a lower lateral member interposed between the vertical members proximate their medial portion, such that the distance between the outside surfaces of the vertical members is generally equal to, and preferably sli...

A seat mounting assembly include a tilt adjustment system wherein the angle of a link on which saddle is mounted may be adjusted via a saddle tilt adjusting mechanism that interconnects base and link members at a position spaced from a moveable connection between the link and base member. The tilt adjusting mechanism is formed by a position adjusting element for adjusting the relative position of the link and base and an independent locking element that unlocks the adjusting mechanism independen...

A shaft manipulating centering and assembly tool for use in a housing bore has four basic members, a manipulating member, a pressing member, a locking member and a power drive member. The manipulating member has an outer surface the radius of the bore and an inner surface that includes one section the radius of the shaft and a flat section. The pressing member has limited rotation within one end of the manipulating member and can push against the bore wall or shaft and can turn the manipulating ...

A system for shaping a single curvature parabolic membrane. The system includes a shaping rail and a bending rail. At least two rollers operably connect the shaping rail and the bending rail. The rollers are operable to alter a position of the shaping rail relative to the bending rail. A compression adjustment bar is operably connected to ends of the shaping rail to apply a load to the shaping rail. A bending adjustment bar is operably connected to ends of the bending rail to apply a moment to t...

An air mattress includes a top; a first fastener member positioned along at least a portion of a side edge of the mattress; a pocket formed on the top by a layer extending along the top and attached along its periphery to the air mattress, at least a portion of the layer being removably connectable to the air mattress by a second corresponding fastener member positioned along a section of the layer; and a visco-elastic pillow top removably received within the pocket. The fasteners may be zippers...

To perform a distributed transaction in a CORBA environment, OTS (the CORBA Transaction Service) defines a process called "control object interpositioning". It must be carried out on the server side to ensure transaction integrity. However, for middle-tier servers (servers that do not access a database directly) this process is not necessary. The control object can be simply passed through. However, the two propagation methods of OTS do not provide a good way to take advantage of this fact. The ...

An air mattress with a pillow top is disclosed. The pillow top is received on and extends at least partially across at least one of planar face of the mattress, and is constructed and arranged to be held in a fixed position relative to the face of the mattress on which it is received. The pillow top may be removably or permanently affixed to the air mattress, as desired. The pillow top is configured to include bead channels, each bead channels having wide portions and narrow portions, the narrow...
