Title: Snap-on wear pad
IPC: B62D55/20
Filed: 1977-12-02
Abstract: A snap-on wear pad is adapted to be used on conveyor chains. The wear pad includes a resilient, generally cylindrical body portion of a length adapted to fit between the opposite inner side bars of a conveyor chain. The body portion has an axial through hole and an axial entrance slot communicating with the through hole from the outer surface of the body, whereby the body can be snapped onto and resiliently held around the chain roller, bushing, or pin. The wear surface comprises an integral tab portion on the surface of the body opposite the entrance slot, providing an abrasive-resistant sliding surface and means to prevent rotation of the wear pad about the chain roller, bushing, or pin. An alternate construction comprises a composite two-piece wear pad assembly in which identical wear pad halves are similarly snapped onto the chain roller, bushing, or pin from opposite sides to provide a wear surface for both sides of the chain.

Patent ES-482628-A1 (ES)
Title: Method and apparatus for testing the setting of a valve.
IPC: F16K37/00
Filed: 1979-07-19
Abstract: A method and apparatus for testing the setting of a valve (particularly a safety valve mounted on a vessel) comprising a valve member biassed towards a valve seat, employs a pulling device which is engaged with the valve member and operated to apply a tractive force opposed to the bias which is just sufficient to separate the valve member from the valve seat. The pulling device is preferably operated by a hydraulic or pneumatic pump. The hydraulic or pneumatic pressure which is just sufficient to separate the valve member from the valve seat is indicated by a suitable gauge and is proportional to the tractive force. The sum of the tractive force and the force acting on the valve from inside the vessel and which can be calculated from the internal pressure indicated on a pressure gauge communicating with the interior of the vessel is indicative of the setting of the valve. The separation of the valve member from the valve seat is conveniently indicated by bubbles in a layer of liquid overlying the valve member.

Patent ES-488189-A1 (ES)
Title: Return line filter
IPC: B01D29/00
Filed: 1980-02-01
Abstract: An improved return line filter is provided for use with a fluid system having a fluid reservoir which is at least partly filled with a fluid. The return line filter comprises an elongated housing having an open top and a partially open bottom and in which the housing is positioned within the reservoir so that the lower end of the housing is submerged in the reservoir fluid. A fluid inlet is formed on the lower end of the housing. A filter assembly is provided for use with the housing and comprises a tubular filter element open at each end and a holder assembly which is detachably secured to one axial end of the filter element. The entire filter assembly is insertable through the open top of the housing so that the tubular filter element is positioned coaxially around and spaced radially outwardly from a portion extending upwardly from the housing thus forming an annular chamber therebetween. Fluid seals sealingly connect both axial ends of the filter element with the housing portion while a fluid passageway fluidly connects the housing inlet with the annular inlet chamber. In addition, a deflection and antifoam tube secured to the holder assembly is positioned coaxially around and spaced radially outwardly from the filter element so that fluid flow from the filter element is deflected downwardly toward the partially open bottom of the housing. This construction for the filter assembly creates a reverse fluid flow in which the fluid must first flow upwardly from the bottom of the housing, out through the filter element and subsequently down through the lower open end of the housing.

Patent ES-8101825-A1 (ES)
Title: Adaptive filter with TAP coefficient leakage.
IPC: H03H21/00
Filed: 1980-06-20
Abstract: Adaptive filters are commonly used in echo cancelers and automatic equalizers. Usually adaptive filters include a tapped delay line and apparatus coupled to the delay line for producing a tap coefficient signal, whose sign and magnitude indicate the appropriate correction in adjusting the filter. However, in the presence of input signals having a partial frequency band spectrum, known filters tend to become unstable, e.g., tap coefficient signals blow up. The instant arrangement includes apparatus for weakly driving the tap coefficient signals to optimal values. As illustrated in a deceptively simple embodiment, a tap coefficient updating component is extended through a one's complement converter to a first input of a binary adder. A two's complement output of the adder is fed back to a second input of the adder. The sign of the adder output is also provided to a CARRY-IN input terminal of the adder. Functionally, a unit leak is introduced in the least significant bit of the adder output tap coefficient signal whenever the updating component and the tap coefficient signal are of opposite algebraic signs. Otherwise, no leak is introduced. Thereby the tap coefficient signal is weakly driven toward zero.

Patent ES-8301258-A1 (ES)
Title: Vulcanisable rubber composition.
IPC: C08L11/00
Filed: 1981-09-02
Abstract: A vulcanizable rubber mixture for producing a leather-hard rubber, which mixture is suitable for use in making a composite profile produced by simultaneous extrusion and vulcanization of two different grades of rubber. The composite profile has a region of leather-hard rubber which serves as the clamping part, and a second zone made integrally therewith, of ordinary soft, rubber-elastic rubber. The vulcanizable rubber mixture for producing a leather-hard mixture contains 20 to 40 parts by weight of polar rubber, i.e. rubber which splits off acid groups under vulcanizing conditions, e.g. polychloroprene, and 60 to 80 parts non-polar rubber, i.e. will not split off said groups, e.g. nitrile rubber, 15 to 50 parts phenolformaldehyde reinforcement resin, 0.5 to 4 parts hexamethylene tetramine, and 0.5 to 3 parts sulfur. Conventional accelerators and zinc oxide are added. Excessive pore formation during the vulcanizing is repressed by the addition of the polar rubber which splits off acid groups under vulcanizing conditions. Other excellent properties are increased toughness in cutting and stamping, reduced splintering, low shrinkage, good injectability, and insignificant production of sulfur dioxide.

Title: Keyboard key with embedded top character
IPC: C09D11/10
Filed: 1982-06-04
Abstract: A printing ink is vulcanized on the top surface of an operation indicating member consisting of a silicone-type elastomer and is integrated with the elastomer to form a character of a predetermined shape on the top surface. The printing ink consists essentially of a material which exhibits a vulcanizing mechanism similar to that of the silicon-type elastomer. In manufacturing the operation indicating member, the predetermined character is formed by means of the printing ink on a transfer plate disposed within a mold for molding the body of the indicating member. Next, the silicon-type elastomer is introduced into the mold and heated under elevated pressure to vulcanize and integrate the character on the transfer plate and the silicone-type elastomer, whereby the character is integrally embedded in the top surface of the operation indicating member formed in the mold.

Title: PLL Oscillator synchronizing system with DC control of free-running frequency
IPC: H03L7/08
Filed: 1983-05-20
Abstract: Color reference oscillator comprises a non-inverting amplifier, with positive feedback via a crystal filter linking its output and input. A quadrature phase shift network, coupled to the filter output, delivers phase shifted signals to a pair of independently controlled amplifiers. One of the controlled amplifiers is responsive to control voltage outputs of a burst-responsive phase detector so as to inject phase shifted signals into the oscillator loop, as and when required, to effect synchronization of oscillator with burst component of incoming color television signal. The second of the controlled amplifiers is responsive to a reference DC voltage and to a manually adjustable DC control voltage, and develops a phase shifted signal output, of a magnitude and polarity dependent upon the magnitude and sense of the difference, if any, between the respective DC voltages, for combination with the non-inverting amplifier's output. Variation of the manually adjustable control voltage effects an adjustment of the free-running frequency of the oscillator.
