Abstract: An electronic method for distributing printed media to subscriber stations for viewing on a personal computer and corresponding electronic distribution system is afforded by this invention. Mass distribution of newspaper or periodical magazine copy is made feasible by converting the copy into an electronic data flow stream format with sequentially represented computer files identified for reception, selection and extraction at a subscriber's computer system. This data stream then is transmitted en masse in this format over a narrow bandwidth transmission channel without filtering or logical processing for local area broadcast over a commercial FM broadcast station on a subcarrier frequency. There selected files are extracted at subscriber reception stations from the data flow stream and stored for interactive manipulation and viewing either as printed media or as an image on a PC viewing monitor.

Abstract: A control arm arrangement for a road vehicle brake lever (1) comprises a control arm (3) pivotally connected to the brake lever and an anchor bracket (4) for attachment to an underframe part (2) of the vehicle. Facing ends of the control arm and the anchor bracket are provided with flanges (10, 11), so that the closely cooperating ends are U-shaped in cross-section.

Abstract: A rotatable-in-place, powered riding vehicle typically may be used as a lawnmower, garden tractor, wheelchair, or warehouse utility truck. Its simplified construction and operator controls facilitate steering maneuverability. Thus the vehicle can be used in tight working places such as narrow aisles, for turning around at the end of rows, and steering around abutments disposed in the travel path, all in forward drive without requiring a reverse gear transmission. This provides more safety and simpler turning than in vehicles requiring a reverse transmission. Also, the vehicle is simplified, quite inexpensive and requires little maintenance and repair. Thus, the set of wheels pivotably mounted and simple control mechanisms provide optimum pivoting in both forward motion and the rotation-in-place steering functions.

Abstract: An end piece or barrel head (1) for a rail vehicle axial slack adjuster is at its outer periphery connected to a barrel (2) of the adjuster and is arranged around a rotatably and axially movable tube (3). The end piece is provided with an internal, circumferential groove (4), connected to the exterior by way of a number of channels (5) opening in the end wall (1') of the end piece for allowing water collected in the groove to freely pass out to the exterior. The end piece is extended further into the barrel by way of a sleeve (1"), which is connected to the groove by way of notches (6) and contains a sealing ring (7) engaging the tube and sealingly cooperating with the sleeve.

Abstract: Modular conveyor belt links have edge structure for occluding exit of pivot rods from the edge of the belt during operation of conveyor belts formed from pivotably connected end-to-end links. The links feature belt edge structure with an outer pivot rod entry aperture offset from the axis of aligned link end pivot rod holes in one set of link ends thereby forming a pivot joint axis. When the pivot rod is forced from the belt edge into the offset aperture and headed toward the pivot joint the plastic link is elastically deformed enough to permit entry of the rod. For example, an occlusion barrier wall disposed near the belt edge retains the rod in the pivot joint. A matrixing nest for the end of the pivot rod resident in its axial joint site is formed in the link material. From this nest the rod can be removed only by forced distortion of a rod end by a force greater than those forces encountered in the course of normal belt operation.

Abstract: An article removal platform assembly with laterally movable finger plate is provided particularly suitable for abutting a conveyor belt as it passes over a sprocket wheel to remove glass articles and broken glass fragments from the belt. The generally rectangular finger plates are mounted in a lateral sliding configuration to a planar platform by at least three fasteners extending through mounting apertures through the finger plates 50, spaced to prevent lateral or longitudinal tilt. The mount has elongated fastening members adjustably aligned to let fingers mate in a conveyor belt and freely slide laterally a limited amount in either direction. Thus, the finger plates can slide side-to-side to follow belt wander when the fasteners engage ridges of the apertures through the finger plates. Also provided are snap-in caps for the apertures for maintaining a planar discharge surface having a constant coefficient of sliding friction that does not accumulate residue.

Abstract: In a sun-and-planet toothed wheel gearing the width of the tooth spaces of the toothing of the hollow wheel is preferably made three times larger than at a common toothing with substantially the identical widths of the teeth and tooth spaces. Such a inventive toothing can be produced specifically simple and precise by means of non-cutting methods, preferably an impact rolling.

Abstract: It is critical to prevent muscular damage to an athlete in a machine that produces a restraining force that must be overcome in the initial part of an exercise stroke. This is achieved by a precise and accurate type of control system by which the athlete safely and surely control the initial restraining force magnitude. With a reliable vernier type control device the athlete then may "inch-by-inch" increase the restraining force as the muscles become able to overcome greater forces in the manner the proverbial strong man lifts a calf each day so that he can lift a full grown cow eventually. In a preferred embodiment of this vernier type control the restraining device comprises an electromagnet with a retained magnetic member coupled to the athlete by an intermediate muscular operated linkage.

Abstract: The display rack of this invention improves the status of the prior art by incorporating the following functional features, namely: (1) compact profile for high density storage and display of various merchandise configurations, (2) breakdown into easily handled, stored and shipped basic pieces, (3) easily assembled construction of few pieces, and (4) attractive display of a wide variety of stored merchandise. This is achieved by the novel construction afforded by two basic lightweight wire grid framework panels held together in a T-shaped configuration adapted to receive removably mounted shelves in a variety of locations within the confines of a rectangular parallelpiped defined by the framework. The shelves are basket shaped and adapted to mount explicitly for products of various heights on opposite sides of the T leg panel.

Abstract: There is no prior way to retrofit one or more laterally extending electrical boxes for extra switches, outlets or accessories such as rheostatic controls in existing walls without tearing out a portion of the wall, removing the box, rewiring a new ganged box and refinishing the wall. This invention provides modular lateral box extensions constructed to be installed from the open front end and supported by the installed box anchored to a beam with the wall being cut only enough to receive the extension modular box. This efficiently requires the wiring of only additional modules and avoids repair and repainting of walls.

Abstract: This rotary filament vegetation trimmer improves the life expectancy of plastic filaments by improved and simplified control of a refrigerated air flow path about the filament of sufficient magnitude to prevent overheating resulting in catastrophic failure from the stresses of twisting as the rotary trimmer head whirls the filament at high rotation speeds. Thus, the head and its filament passageway therethrough are shaped to constitute a centrifugal air pump that draws both air and the filament through the head to position the filament for trimming. The passageway diverges from the shaft into a chamber of significantly increased volume to produce expanding and refrigerated air in the critical region at which the filament curves and induces twisting as the head rotates to tend to heat and cause failure of the plastic filament.

Abstract: A tool for compressing and holding the internal spring of a rotary joint 15 for the easy and safe removal and installation of the assembly plate screw/s having at one end an anchor (1) perpendicular to a spacer (2), which is perpendicular to a riser (3), which is parallel to the anchor. The end of the riser opposite the spacer is connected to a lever (4) at hinge (9). The hinge is secured with hinge pin (10) and allows the lever to fold parallel to the spacer. A bell hanger (5) is connected to the lever parallel to the spacer when in the extended position and parallel to the riser when in the folded position. The bell hanger is inserted into a bell (6) and retainer (8) which are secured by a bell keeper (7).

Abstract: The toothed-wheel gear with parallel shafts and load branching comprises a driving wheel (1), intermediate wheels (2;2') and a power wheel (3), wherein the driving wheel is guided between the intermediate wheels (2), e.g. in guide bearings (4), in such a manner that the driving wheel (1) can self-shift, in operation, along a plane inclined by an angle (.alpha.) and axis parallel to a plane containing the axis of the driving wheel and the power wheel, to such an extent that the balance of forces is reestablished.

Abstract: This invention relates to a simplified, substantially self contained fuel savings control system for in-room air conditioner/heater units, which automatically turns off the power when the room is unoccupied. The system is typically contained in a single housing unit that may be plugged in between an in-room power line outlet and a power cord to the heater-cooler unit. The system is universal in scope, being adaptable to different kinds of thermostatically controlled systems powered from a local power line. That is achieved, in part, by letting the temperature controls built into in-room thermostatically controlled units establish the temperature and controlling the power to the in-room units by sensing room occupancy and removing power when the room is unoccupied.
