A pair of garden shears is provided with a debris catcher that is attached to the back edge of each blade. Each debris catcher is transversely curved to extend over the blade and terminate in an upper edge that faces the upper edge of the other catcher. The catcher upper edges abut with one another to grip plant material therebetween and hold such plant material after it is cut by the blades. In addition, the transversely curved body of the catcher forms an upwardly facing, upwardly curved troug...

A pressure regulating valve usable in combination with a hydraulic steering system has a spring mechanism axially disposed between a pair of axially aligned valve spools. Movement of the spring mechanism in a first direction resiliently moves one of the valve spools to a position for communicating an inlet port with a control port and regulating the pressure in the the control port so that the pressure is proportional to the degree of movement of the spring mechanism. Conversely, movement of the...

A collet assembly, for selectively attaching a tool accessory to a tool, having a collet nut rotatably connectable to the tool, a collet compressible by the collet nut, and a torque application feature movably connected with the tool. The torque application feature is cammingly actuated to engage the collet nut for compressing and loosening the collet.

A combination low-pressure, high-pressure hydraulic pump which allows a constant differntial pressure is disclosed. This pump features dual concentric pistons, each with its own chamber. The pistons reciprocate together at low pressures; as the system pressure increases, a spring resists the stroke of the low pressure piston, so that ultimately only the smaller, high pressure piston reciprocates.

A transmitter for a LAN electro-optical interface, capable of transmitting data at a rate of at least 50 MBd is disclosed. The transmitter includes a parallel gating circuit for providing a high current drive signal in response to a data signal, and a parallel resistor capacitor circuit, connected between the parallel gating circuit and a light transmitting device, for improving the leading edge response time of the light transmitting device.

Quasi-phasematching design to provide an approximation to a desired spectral amplitude response A(f) is provided. An initial phase response .phi.(f) corresponding to A(f) is generated. Preferably, d.sup.2.phi.(f)/df.sup.2 is proportional to A.sup.2(f). Alternatively, .phi.(f) can be a polynomial in f. A function h(x) is computed such that h(x) and H(f)=A(f)exp(i.phi.(f)) are a Fourier transform pair. A domain pattern function d(x) can be computed by binarizing h(x) (i.e., approximating h(x) with...

These and other objectives are attained with a method and system for updating software applications or systems on a target client. The method comprises the steps of providing the target client with an update manager; and using the update manager to initiate a procedure to compare the level of software or services on the target client with the level of software or services available on a specified server to determine if an update is available on the server for the software or services on the targ...

A system to provide narrowcast communications uses adaptive data rate control to individual subscribers such that the effects of precipitation or other link conditions, which are not common to all subscribers, is mitigated. The invention takes advantage of the fact that the narrowcast data consist of packets which are individually addressed to specific subscribers, or groups of subscribers. The narrowcast data is communicated on a plurality of FDM carriers, each of potentially differing data rat...

A paint shield for masking a door or window frame, or painting an adjacent wall and a method for its use are disclosed. The paint shield includes a substantially planar, rectangular portion of sheet like material. A substantially planar blade portion extends at right angles to the rectangular portion and has a width greater than or equal to the thickness of the frame to be masked. The blade portion terminates in a straight edge. A handle is affixed to the rectangular portion and is used to posit...

A holesaw mandrel assembly has a mandrel with a first shanking end, a body, and a second extending end which includes a threaded spud to receive a holesaw. A first member is secured on the second end. The first member is axially slidable on the second end. The first member also includes a friction surface to contact the holesaw. The friction surface moves between a first contacting position and a second release position. A mechanism on the mandrel moves the friction surface between the first and...
