Patent number: RE28775Abstract: An electronic, undamped oscillator driven by a periodic input signal (forcing function) having a frequency equal to the natural frequency of the oscillator develops an output sinusoidal signal having a rate of growth (amplitude increase) proportional to the amplitude of the first harmonic component of the input signal. When the input signal is a force variation signal and the oscillator is tuned to the rotational frequency of a tire mounted on the force variation machine, the rate of growth of the output signal of the oscillator is proportional to the amplitude of the force variation signal. A peak follower detects the amplitude of the increments between successive peaks of the oscillator output signal. A meter indicates the amplitude of the successive peaks of the oscillator output signal, thereby indicating the amplitude of the first harmonic component of the force variation signal.Type: GrantFiled: March 1, 1971Date of Patent: April 20, 1976Assignee: Uniroyal Inc.Inventors: Haig D. Tarpinian, Harry Friedmann

Patent number: 3950821Abstract: A tube-like socket is provided in a machine for stuffing sausage and the like. A nozzle is swingably or pivotally mounted for swinging movement between operating position in which a sausage tubing feeds between the socket and nozzle, and idle position away from the socket. A hook-like structure is pivotally converted to the mounting mechanism for the nozzle such that it projects through the nozzle with the nozzle in idle position and automatically feeds sausage tubing through the nozzle as the nozzle is swung to operating position.Type: GrantFiled: August 26, 1974Date of Patent: April 20, 1976Assignee: VEMAG Verdener Maschinen und Apparatebau GmbHInventor: Manfred Plewa

Patent number: 3950826Abstract: A seat belt system is disclosed for mounting relative to the seat assembly of a vehicle which includes one or more harness restraint adjuster devices having retaining means including a pair of cooperating clamping members for engagement with opposite sides of the webbing belt. The clamping members are normally closed on the belt to anchor it in a fixed position, but manual release means allows for disengagement of the clamping members to vary the length of the seat belt system. The belt is free to move within the restraint adjuster in one direction without any need to utilize the release means, and the retaining means automatically reclamps itself against the belt when the adjustment is completed.Guide means including spaced apart fixed bearing surfaces are assembled to side members of the support means and are so located as to limit the forward translation of the clamping members while there is tension in the springs.Type: GrantFiled: August 7, 1975Date of Patent: April 20, 1976Assignee: East/West Industries, Inc.Inventors: Frank Knoll, George Skridul
