Title: Narrow profile power handle for line trimmer and the like
IPC: F02B63/02
Filed: 1981-02-16
Abstract: A narrow profile power handle uniquely adapted for use as a flexible line trimmer having improved handling and safety features is disclosed. The power handle is also equipped with a quick connect and disconnect coupling and is useful for driving attachments to produce hand held rotary implements and tools such as brush cutters, edgers, cultivators, drills, etc., hand held reciprocating implements and tools such as hedge clippers, saws, etc., as well as portable water pumps, air compressors, generators, etc. The crankshaft of a two-stroke internal combustion engine is disposed along the longitudinal axis of a narrow profile housing which includes a rear handle having a hand grip portion disposed above and projecting rearwardly parallel to the axis of the housing. The cylinder extends upwardly from the crankcase, the carburetor is disposed below the crankcase, the flywheel, ignition system and starter to the rear, and the gas tank is disposed below the rear handle. The muffler is disposed along the forward face of the housing for discharging products of combustion forwardly of the housing and away from the operator, thereby permitting the assembly to be rotated for various trimming operations without exposing the operator to the risk of burn injury. A recoil starter handle, a choke control, throttle control and ignition kill switch are conveniently clustered around and near the hand grip portion of the rear handle which allows the operator to observe and exercise positive control over both the power handle and the cutter head while starting and operating the engine. The power handle includes a quick disconnect coupling for attaching the portable power unit to drive various attachments. As a result of this arrangement, the power handle is generally symmetrical about the longitudinal vertical plane and is of minimum width. The drive shaft of the line trimmer assembly is aligned with the crankshaft of the engine and a forward handle is disposed above the drive shaft ahead of the engine housing. As a result, the center of gravity of the overall line trimmer assembly is below and between the forward and rearward handles, thereby providing improved balance and maneuverability.

Patent ES-8205046-A1 (ES)
Title: Disc brakes and friction pad assemblies therefor
IPC: F16D65/097
Filed: 1981-02-27
Abstract: The present invention provides a friction pad assembly comprising a backing plate and a pad of friction material secured thereto, the backing plate having at least one hole offset from the central axis of the assembly, through which a pad support pin passes to engage a wire spring supported on the backing plate and having two generally oppositely directed arms. The arms engage either the pad support pins and/or part of the brake and produce an asymmetric loading of the pad assembly, the spring biassing the friction pad assembly against an abutment face of the brake to thus reduce the possibility of the pad assembly hitting the abutment face to produce disturbing 'klonking'.

Patent ES-8503093-A1 (ES)
Title: Telescopic shock absorber (damper)
IPC: F16F5/00
Filed: 1983-09-19
Abstract: A shock absorber 10 is equipped with a rebound (bounce) suppression assembly 22. The rebound suppression assembly 22 rests on a projection 30 secured on a piston rod 16. The rebound suppression assembly 22 includes an elastomeric ring 24 placed between two collars 26 and 28 which together form an annular chamber 74. At the end of the rebound travel of the piston rod 16, the rebound suppression assembly 22 is compressed in the axial direction between the projection 30 of the piston rod 16 and the rod guide 18 until the elastomeric ring 24 deforms in order to enter into contact with the inner wall 64 of the working cylinder. When the elastomeric ring deforms, the volume of the annular chamber is reduced. A restrictive passage 71 allows limited circulation of fluid from it. A supplementary chamber 70 is formed which is in limited fluid communication through the passage 71 with the cross section 68 of the rebound chamber 20. Supplementary compression of the rebound suppression assembly 22 reduces the volume of both chambers 70 and 74 and gives rise to limited fluid circulation from them through the passage 71 to the cross section 68 of the rebound chamber 20. Compression of the elastomeric ring and limited fluid circulation guarantee additional damping at the end of the rebound travel.

Patent ES-8507654-A1 (ES)
Title: Regenerating catalytic particulate filters and apparatus therefor
IPC: F01N3/28
Filed: 1983-12-02
Abstract: A method and apparatus for regenerating a catalyzed particulate filter in the exhaust stream of a combustion source (particularly a diesel engine) are provided that do not necessitate excessive heating of the exhaust stream flowing from the combustion source. During regeneration the intake air is supplied in a pulsed manner, preferably but not necessarily, to less than all of the cylinders of the engine so that the combined engine exhaust carries sufficient "fuel", primarily in the form of a carbon monoxide and a hydrocarbon fraction, that will be catalytically oxidized thereby generating an exotherm. Due to the liberation of heat during that carbon monoxide and hydrocarbon oxidation above the light-off temperature of the filter, the particulates stored by the filter will be ignited and burned cleaning and regenerating the filter.

Patent ES-8502782-A1 (ES)
Title: Arrangement for determining the travel of a piston
IPC: F15B15/28
Filed: 1984-05-24
Abstract: An arrangement for determining and measuring the position or travel of a piston in a cylinder, e.g., suspension component such as a vibration damper, gas-spring or hydropneumatic suspension, uses a structure having no moving electrical contacts, nor any movable electrical leads. The arrangement measures a variable impedance, e.g., a capacitance which is created by first and second electrodes formed within the suspension component and is distinguished in that the electrodes are fixed and are immovable with respect to each other. Capacitance variation is achieved, for example, by allowing a dielectric medium, such as a ceramic or epoxy resin cylinder to enter between two electrodes, the extent of the entry of the dielectric medium being made to be proportional to the relative travel of the piston in the cylinder. In a variation, an additional electrode forming a fixed reference capacitance with the first electrode is provided. The fixed reference capacitance is used together with the measured variable capacitance in a measuring bridge, e.g., Wheatstone bridge, so that undesirable effects of varying temperature and pressure on the capacitances inside the suspension component are compensated during measurement. By virtue of the fact that all the electrodes are fixed relative to one another, the conductive leads from the fixed electrodes can be made immovable relative to each other, whereby measurement problems owing to improper leads and connections are eliminated.
Patent ES-8503802-A1 (ES)
Title: Double-tube vibration damper unit
IPC: F16F9/40
Filed: 1984-06-15
Abstract: In a double-tube vibration damper the cylinder engages by a terminal edge thereof an engagement face of a piston rod guiding and sealing unit. When the piston rod moves in the outward direction with respect to the cylinder, a high pressure occurs in the working chamber adjacent the piston rod guiding and sealing unit. Due to this high pressure damping liquid jets may escape between the terminal edge of the cylinder and the engagement face of the piston rod guiding and sealing unit. These liquid jets may cause foaming within the annular space defined between the cylinder and a container surrounding the cylinder. In view of avoiding such foaming, an annular cover member is provided between the cylinder and the container, which annular cover member prevents the direct entrance of liquid jets into the annular space between the cylinder and the container. This annular cover member is situated such that it extends across the plane of engagement defined by the terminal edge of the cylinder and extends perpendicular with respect to the axis of the cylinder.
