Inventor: GOODRICH ROBERT R
IPC: G07F1/04
Filed: 1991-01-23
Abstract: A coin chute includes a coin entrance, clear-out apparatus, coin processing apparatus, a return chute and a coin ejector. The clear-out apparatus is positioned between the coin entrance and the coin processing apparatus. It comprises a cavity for trapping unwanted material stuffed into the coin entrance and a pair of sidewalls (inner and outer) that move in response to the operation of the coin ejector. A deflector plate, positioned within the cavity, assists in trapping the unwanted material. The outer sidewall permits trapped material to fall into the return chute while the inner sidewall pushes this material into the return chute. The coin ejector includes an actuator that is operatively connected to the sidewalls of the clear-out apparatus by a helical spring whose restorative force is sufficient to urge material trapped within the cavity into the return chute, but not sufficient to damage the coin ejector when excessive force is applied to the actuator.

Abstract: A composition for removing organic contaminants, such a flux residues, from a solid substrate comprises: (a) hydrogen peroxide in the amount of about 3 to 5 percent by weight of the composition; (b) an alkaline compound in sufficient amount to provide a pH of at least 10.5 in the composition; (c) about 0.1 to 0.3 percent by weight of a chosen wetting agent which is unreactive with the hydrogen peroxide and the alkaline compound; and (d) purified water as the balance of the composition.  Optionally, the composition may further comprise about 0.5 to 2.0 percent by weight of a chosen metal protective agent.  The solid substrate having organic contaminants thereon is exposed to the above-noted composition whereby the organic contaminants are removed from the substrate and are converted into non-toxic and non-hazardous products.  Thus, negative environmental impact is avoided by the present process. In an alternative embodiment, the organic contaminant removal is further enhanced by exposing the composition and the organic contaminants on the substrate to ultraviolet radiation.

Patent CA-2045301-A1 (CA)
Title: Mobile telephony system
Inventor: ISRAELSSON PER V
IPC: H04B10/114
Filed: 1991-06-24
Abstract: A mobile telephony system intended for use by outdoor subscribers, for instance in cars, while affording, at the same time, high traffic capacity and relatively disturbance-free speech transmission to subscribers located within a building, for instance an office building. Signal transmission between mobile stations and base stations is effected with radio waves in a first sub-system for instance intended for telephony traffic via car telephones, and with light, at least in the area nearest the mobile stations, in a second sub-system intended, for instance, for an office building. Signal transmission with light can also be effected in areas that contain electronic apparatus which is sensitive to radio disturbances, for instance in hospitals and/or in areas in which strong radio disturbances capable of preventing mobile telephony transmission with radio waves occur. Certain mobile stations may be capable of being switched between signal transmission with radio waves and signal transmission with light, which enables these stations to be used in both subsystems.
Patent CA-2046167-A1 (CA)
Title: Articulated crank for a bicycle or other crank-driven device
Inventor: WIENS ERWIN J
IPC: B62M11/18
Filed: 1991-07-03
Abstract: Abstract The efficiency of a conventional bicycle crank is diminished mechanically by a substantial 'dead zone' at the top and bottom of the crank cycle, and ergonomically by straining certain muscles in the hip and thigh while failing to deploy other muscle groups to their full potential.  These inefficiencies are resolved by a bicycle crank assembly consisting of articulated crank arms whose joints are attached to cogs or sprockets which orbit around a stationary gear fixed to the frame of the bicycle (either a sprocket, spur gear, or an internal ring gear), such that the pedal ends of the crank arms trace a hypocycloidal curve that approximates a narrow ellipse.  In the latter case (where the stationary gear is an internal ring gear), the fixed gear constitutes a much enlarged bottom bracket.  In the preferred embodiment of the invention, two cogs orbit within the ring gear, held between two parallel discs, such that the whole assembly rotates within the stationary ring gear.  When the crank arms attached to the orbiting cogs rotate counter-clockwise, the whole assembly held by the two disks is caused to rotate clockwise. Conventional chain rings are attached to the righthand disc.  In the former case (where the stationary gear is a sprocket or spur gear), the fixed gear does not mesh with the orbiting cogs directly, but by means of a chain or belt.  The chain ring is then fixed to a centrally mounted spindle that connects the left and right-hand crank assemblies.
