A buffer, especially for cranes, which includes a top plate and a bottom plate confining therebetween a plurality of discs of circular elastic material which are bonded to each other and to the head and foot plate while a holding member extends through passages in the plates located between the head and foot plate and is connected to the head and foot plate, the internal plates between the head plate and foot plate are provided with axially aligned passages the inner diameter of which is a multi...

A buffer is disclosed. The buffer may include a buffer controller for buffering a refresh signal enabled in an auto-refresh operation synchronously with an external clock signal, a logic circuit for performing a logic operation with respect to an output signal from the buffer controller and a specific signal to output a control signal, and an internal clock generator controlled by the control signal from the logic circuit for buffering the external clock signal and generating internal clock sign...

A buffer comprising a plunger slidable in a ported tube. A metal tubular member circumferentially surrounds that part of the ported tube in which all the flow resisting ports are formed and is the radially inner wall of an annular space filled with compressed gas. The outer wall of an annular space is formed by a tubular membrane. The annular chamber between the ported tube and the metal tubular member is part of a low pressure reservoir of the buffer and communicates via an annular passage in t...

A buffer includes a grommet having a tube portion, an attaching portion and an elastic engaging piece projecting inside the tube portion; an engaging member having an engaging step portion provided on an outer surface thereof for engaging the elastic engaging piece to prevent the engaging member from coming out in a counter-insertion direction when the engaging member is inserted into the tube portion in an insertion direction; and a damper main member having an abutting portion provided in a mi...

A switched capacitor buffer operating by the push-pull method is taught. The buffer may include a pull-up device and a pull-down device. A switched capacitor circuit may be used to control the pull-up device and the pull-down device to achieve accurate push-pull operation. According to some embodiments, the switched capacitor buffer displays an optimal combination of design simplicity, low power consumption and high-frequency response.

A buffer includes a pull-down means, a pull-up means, and a control signal generator. The pull-down means generates an output signal that transitions to a first state at a relatively high speed when an input signal transitions from a first state to a second state in response to a control signal at a first control state. The pull-up means generates an output signal that transitions to the second state at a relatively high speed when an input signal transitions from the second state to the first s...

An improved floor buffer for operator directed polishing of a floor is disclosed. A carriage disposed substantially horizontal to the floor has a lower surface exposed to the floor and an upper surface exposed away from the floor. A handle is attached to one end of the carriage. The handle extends angularly upward and away from the carriage toward the operator overlying an axis extending longitudinally of and from the carriage. At least two wheels are rotatably mounted to the carriage. These whe...

A buffer structure in which a plurality of buffer bodies separated from each other by intermediate disc means are in axial direction located one behind the other and with radial play are arranged in a tubular member which has one end closed and has a push rod slidably arranged in the other end portion of the tubular member. The disc means are preferably provided with peripheral annular flange means slidably engaging the inner wall surface of the tubular member and defining annular grooves receiv...

A hydraulic buffer especially suitable for heavy duty uses has a minimum number of rugged parts including a metering orifice cylinder closed at one end and enclosed within a housing providing a hydraulic fluid reservoir, with a piston reciprocable in fluid displacing relation within the cylinder and having a hollow piston within which is received a coil spring seated on the cylinder end closure and normally biasing the piston and rod into protracted relation relative to the housing to receive fo...

A machine for buffing worn tire casings to prepare them for retreading which includes a rotary tire casing support and a pair of powered rotary rasps engageable with a tire casing on said support, the tire casing support being movable toward and away from said rasps and the rasps being located approximately rearwardly of the tire casing support control means located at the opposite radial side of a tire casing support so that the operator can stand adjacent to one part of the tire casing support...
