Abstract: S P E C I F I C A T I O N     BACK-PEDAL BRAKE OPERATOR FOR MULTI-SPEED BICYCLES                    Inventor: Franklin J. Calderazzo ABSTRACT OF THE DISCLOSURE     Back-pedal. brake operator for multi-speed bicycles, such as chain-derailer bicycles or gear-shifting bicycles, which can be used to operate the brakes for either the rear wheel or the front wheel or both.  The brake operating action is obtained by turning the foot pedals rearwardly a short dis-tance from any position which the pedals may occupy at the instant when the driver wishes to apply braking action, the braking operation being obtained without utilizing the sprock-et chain to apply the braking force, and the brakes are auto-matically released without any "lock-up" effect when the driver starts pedaling forward in the normal manner.  Advan-tageously, the back-pedal operators shown are directly associated with the sprocket assembly as a compact self-con-tained unit integrated with the sprocket assembly and can be installed as original equipment by bicycle manufacturers or can be retrofitted by bicycle shops or owners on existing multi-speed bicycles.  The bicycle is permitted to be wheeled freely rearwardly without the brakes becoming applied.   The back-pedal brake operator can be adapted for adjustable automatic proportioning of the relative braking efforts to be exerted on the rear and front wheels.   This invention also enables dual actuated braking systems to be installed in multi-speed bicycles for either hand or foot operation (or both) of the brakes.

Abstract: A B S T R A C T           This invention relates to a process for preparing polyurethane/vinyl polymer articles and to the articles prepared from the process.  The process comprises (1) admixing a liquid polyol, a polyisocyanate, a catalyst for urethane formation, an ethylenically unsaturated monomer and a catalyst for polymerising an ethylenically unsaturated monomer, (2) pouring the reaction mixture into a mold and allowing it to react and to solidify, and (3) demolding the resultant articles from the mold. The process of the invention is characterized in that in step (1) one employs a liquid polyol having from 2 to 8 hydroxyl groups per molecule and having a hydroxyl equivalent weight from 30 to 250.  The process is further characterized in that one employs less than 60 percent by weight of the ethylenically unsaturated monomer based upon the combined weights of the polyol, the polyisocyanate, and the ethylenically unsaturated monomer.  The process of the invention is well suited to produce cellular or non-cellular articles as, for example, furniture components, ornamental or decorative objects, piping elements, machine components, or structural members.

Abstract: Abstract of the Disclosure A method and apparatus for the excitation and spectral calibration of acoustic emission systems in which a helium or other gas jet is used as a calibration source which makes no mechanical contact with the specimen or structure under examination.  The gas jet which simulates an acoustic emission event, is sprayed on a reference material which is acoustically coupled to either an acoustic emission transducer or to a transducer having a flat fre-quency response up to 1 MHz.  The transducer spectra are measured in decibels and subtracted from each other thereby obtaining a 'transducer calibration".  The "calibrated" transducers are then coupled to a specimen under test, the gas jet is applied and a "gas jet system spectum" is measured.  The spectrum of acoustic emission acitivity is then measured and corrected by subtracting, in decibels, the "gas jet system spectrum", thereby obtaining system independent acoustic emission spectral information which can be used to compare results in other systems.

Abstract: Abstract A drain valve for a compressed air system automatically discharges liquid separated from system air from a container in which the separated liquid is trapped when the trapped liquid activates the drain valve.  A spring biases the valve element of the drain valve to an open position to drain the trapped liquid during system shut-down and is positioned in an outlet passage of the container so that the spring is accessible for replacement without disassembly of the drain valve.  A float in the container is responsive to the level of trapped liquid to open communication between the system pressure and a chamber on the upper side of a diaphragm type valve actuator to offset the system pressure in a chamber on the lower side of the valve actuator so that the spring and the pressure on the upper side of the valve actuator acting on the valve element moves the valve element to its open position for discharging the trapped liquid.  The float includes a cup shaped member whose interior is in the form of an annular chamber with a continuous unbroken surface above its lower end so as to positively trap air therein which prevents excessive amounts of water from entering the float interior whereby water logging of the float is prevented.            The valve element sealingly engages the diaphragm to seal the upper chamber from the lower chamber.

Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed herein is a flexure hinge assembly comprising a pair of coaxial concentric inner and outer tubular members secur-ed one to another, each being divided into at least one driving portion, at least one gimbal portion and at least one driven portion and interconnected by a plurality of flexure blades, all formed by a plurality of slots and apertures through the walls of each tubular member.  The flexure blades are formed by pairs of adjacent apertures with the slots interconnecting apertures to divide the tubular members into the driving, gimbal, and driven portions.  Two diametrically opposite flexure hinges, each com-prising two mutually orthogonal therefore crossed flexure blades, on in the outer and one in the inner member, connect each gimbal portion to the driving portion.  Two other such flexure hinges connect each gimbal portion to the driven portion.         The common plane of flexure of two of the four flexure blades of each tubular member forms a first angle with respect to the common axis of the inner and outer tubular members, the common plane of flexure of the two other flexure blades of each tubular member forms a second angle with respect to the common axis of the inner and outer tubular members, and the difference between the first angle of the two flexure blades of each member and the second angle of the other two flexure blades of that member is substantially 90°.         The crossed flexure blades are fabricated by forming the apertures with the inner and outer tubular members coaxially aligned in a first relative angular position and then rotating the tubular members with respect to one another through a pre-determined angle of rotation into a second relative angular position of the tubular members to create four flexure hinges spaced 90° apart.

Abstract: ABSTRACT OF THE DISCLOSURE                A pair of telescoped inner and outer tubes together provide a post-like handle that is mounted on the gunwale of a boat.  The outer tube is fixed to the top of the gunwale and projects down through a hole in the gunwale, and the inner tube which forms the actual handle slides in the outer tube between a lowered inoperative position beneath the gunwale to a raised operative position standing erect and rising to a convenient height above the gunwale.  A spring-pressed latch moves with the inner tube and snaps into an annular groove that is fixed with respect to the outer tube and located directly above the gunwale, to secure the inner tube against either upward or downward movement. A resiliently manually actuated loop located in the annular groove enables the latch to be dislodged from the groove when it is desired to lower the handle.
