Abstract: A torsional vibration damper of the type having a hub adapted to be coupled to a rotary shaft. The hub carries an elastomer member, the elastomer member in turn carrying an inertia member. A cavity is formed at the interface between the hub and inertia members, the cavity filled with a viscous liquid. The elastomer and the viscous liquid damp torsional vibrations in the rotary shaft. By virtue of the configuration of the hub and inertia members, the elastomer also functions to seal the viscous liquid in the cavity. Further, the configuration obviates the need of separate fasteners to assemble the damper.

Abstract: A high "G" gyro that has a rotor mounted relative to a stator by a fluidic earing with fluidic exhaust control means for producing a lower pressure at the exhaust for the fluidic bearing to prevent the exhaust from the fluidic bearing from impinging on other portions of the rotor to cause error signals to be produced. By locating the exhaust for the fluidic bearing radially outwardly from the inlet ports to the fluidic bearing, and by producing a lower pressure at the exhaust, the exhaust fluids from the bearing are attracted to the exhaust and prevented from impinging and exerting undesirable forces on the rotor.

Abstract: A fly-wheel for a tape recorder has a cup-shaped plate member fixed to the capstan shaft, and a ring-shaped member fixed to the cup-shaped plate member to reduce the weight and cost of the fly-wheel.

Abstract: An engine is disclosed having pistons in operative connection with a crankshaft. A bearing member, defining a curved periphery, is carried on the crankshaft for eccentric rotation thereabout in a direction transverse to the major axis of the crankshaft, with the periphery of the bearing member being positioned to be in power-transmitting, sliding relationship with a connection to the piston. The bearing member is adapted for transverse displacement by the piston rod relative to the crankshaft, while transmitting power to the crankshaft, to absorb any shock generated against the piston and the crankshaft, such as by "engine knock." The bearing member is also adapted for return to its predisplacement position after absorbing the shock.

Abstract: A rotary mechanical amplifier for rapidly switching a controlled member between two positions, which comprises a rotary drum carrying a series of cylindrical rods regularly spaced in circular configuration about the axis of rotation of the drum. Each rod is selectively slidable axially between two positions in response to control signals, for example by means of electromagnetically controlled sprung bolts or catches. In one axial position, the rods tangentially engage a curved surface of a lever or other controlled member to move it to a position where it can be held without vibration by tangential engagement with successive rods.

Abstract: A gyro which has a fluidic bearing with two radially spaced circles of orces and two circumferentially and radially spaced exhausts and jet means for producing low pressures in the circumferential exhausts. By using a jet nozzle exhaust control with radial exhaust outlets between two circles of orifices, fluid from one circle of orifices is allowed to exhaust before it can interfere with the other circle of orifices. The fluidic bearing also has exhaust channels between each of the orifices to reduce turbulence and torques present in this area.

Abstract: A rotary energy storage device formed of discrete annular rings of anisotropic filamentary material disposed within the rings in a "wound" configuration, the upper and lower edges of each ring being attached alternately to the edges on adjacent rings in a radial orientation to form a structure having a bellows-like or convoluted cross-section. The present structure, due to the convoluted nature of the joined rings, is subject to unusually low radial stress within the material when rotating.

Abstract: A control to yieldably restrain the depression of the accelerator pedal of a motor vehicle after a certain initial amount of depression. A spring is coupled at a first end to either the accelerator pedal or throttle linkage such that free travel of the accelerator pedal and linkage is allowed over a predetermined distance, and thereafter further movement of the accelerator pedal and linkage is opposed by the action of the spring second end being biased against a fixed portion of the motor vehicle.

Abstract: A pilgrim step indexing mechanism provided with oppositely facing toothed ratchet wheels of the same pitch is associated with a single indexing pawl and an associated detent spring which not only detentably holds the ratchet wheels but also biases the indexing pawl to engage the ratchet wheels. The indexing pawl has two teeth one of which engages one of the ratchet wheels during a reverse stroke of the pawl to reverse feed both ratchets one increment and during a forward stroke of the pawl to advance both ratchets two increments. The ratchet wheels may be connected with a platen of a printer whereby a line of printwork, after printing, will be positioned two line spaces above the printing line for easy viewing.

Abstract: The invention relates to a variable-profile cam of the kind comprising a cam-surface formed by one of the longitudinal faces of a thin strip extending freely between at least two supports, of which at least one is adjustable transversely in position, in which the thin strip is made of an elastically-deformable material, and the transverse moment of inertia of the strip can vary between the two supports, for example by variation of the width or the thickness of the strip. The invention is particularly applicable to cams for reproducing machines for the production of aspherical surfaces of moulds for contact lenses.
