A security brake system comprising a plurality of braking modules, each module coupled between a brake master cylinder and a set of wheel cylinders of a vehicle, each module further comprising a body having a first, second, third ports, and a plurality of channels disposed therein between the ports, the first port allowing the transfer of braking pressure to the body from the brake master cylinder, the second port allowing the transfer of braking pressure from the body to a set of wheel cylinders, the channels transferring brake pressure therethrough between the ports; a valve mechanism coupled to the third port of the body and extended within a channel between the first and second ports for controlling brake pressure between the first and second ports, whereby allowing the brakes of the vehicle to be locked or unlocked; and an activation mechanism for activating the valve mechanism in one orientation, whereby unlocking the brakes of the vehicle, and deactivating the valve mechanism in another orientation, thereby locking the brakes of the vehicle.

The invention teaches an improved arrow construction which, by the partial or complete elimination of tail feathers as a means for stabilizing flight trajectory, improves both the speed and the accuracy of the arrow. A resilient stabilizing tail is substituted for tail feathers which substantially eliminates aerodynamic drag. In addition, the invention contemplates the use of a 'shock piston' within the interior of the arrow shaft which serves to increase arrow penetration in the target by striking the arrow head after the initial target impact.

Interlocked channel section panels having an interlocking joint wherein the male and female members are provided with deformable hook portions. During field assembly the female member overlies the male member with the outer surface of the corresponding upstanding members and upper portions of the male and female members adapted to mate throughout their lengths, and the deformable flange hook portions of the male and female members are capable of being reformed so as to conform intimately to effect continuous, positive interlocking of male and female ribs. A clip connector, including a body portion tightly sandwiched between associated corresponding upstanding members, upper portions and deformable flange hook portions of the sidewalls of the coupled panels, and a foot at the other end of the body portion of the clip connector anchored to a supporting member and fastening the connector along with the coupled panels to the supporting member, is also provided.

A rolling support for moving scaffolding alongside the side or end of a building under construction, the support including frame structure which rigidly connects two outriggers together, a leading outrigger and a trailing outrigger, each of such outriggers having a near-side traveling wheel to ride on an exposed structural roof member adjacent the side or end of a building, and a far side force roller which extends beneath a parallel exposed structural roof member inwardly from the side or end of the building, the outriggers being parallel to one another and riding on parallel exposed structural roof members. The near-side travel wheel bears down on its exposed roof member and exerts substantial downward pressure thereon while the far-side force roller bears upwardly against the underside of its exposed roof member. Remote controlled motor means are mounted on the frame so as to drive the near-side traveling wheel. Additional frame structure extends from the outriggers beyond the side or end of the building and scaffold structure is attached thereto.

This invention relates to a device useful in making circular shapes of predetermined size on power sanding machines and the like. The device is essentially a fixture which enables a workpiece to be located on an adjustable center so that it can be rotated with respect to a driven sanding disc, polishing wheel, or similar abrasive tools. The device also permits an oversize workpiece to be fed into the sanding disc until the predetermined radius is reached.
