Patent ES-370261-A1 (ES)
Title: Trolley
IPC: B62B3/065
Filed: 1969-08-05
Abstract: A low-lift truck comprises a load support 13 provided on its underside with cams 14 which are supported on rollers 15 on bogies 10 connected together in tandem by links 11, whereby relative horizontal movement between the load support and the bodies causes raising and lowering of the load support. As shown, this relative movement is produced, against the action of a spring 18, by an hydraulic ram 28 which, at one end, is pivoted to a bogie 10 and, at the other end, is mounted in a housing 17 which is pivoted at 17a to side walls of the load support. The housing 17 includes a pump for supplying fluid to the ram, the pump being actuated by a handle 23 which may also operate a pressurerelease valve for lowering the load support. The truck may be coupled to a similar extension unit 32 by means of hooks 33, 34 and connections 37, 38, whereby the load support of the extension unit is raised and lowered with the load support 13. Two or more trucks, with or without extension units 32, may be arranged to run in parallel side-by-side arrangement. They may be connected together or they may run in parallel tracks, Figs. 5-7 (not shown), on the floor of a vehicle, transport container or building.

Patent ES-388165-A1 (ES)
Title: Force variation marker for tires
IPC: G01M1/26
Filed: 1971-02-11
Abstract: A marking pen or similar marking device is used to mark a rotating tire to indicate the location at which a given force variation, as measured by a tire uniformity machine, is generated. As the tire is rotating against the load drum of a uniformity machine, the point on the tire at which this force variation is produced passes beneath the marker at which time a solenoid is activated to abruptly move the maker toward the sidewall of the tire and to cause the marker to mark the tire with a suitable marking fluid such as ink. The abrupt movement of the marker causes it to eject a small amount of the marking fluid and to deposit the fluid on the tire sidewall. To protect the marker from damage in the event that it comes into contact with the rotating tire, the marker is mounted on a carriage that is pivotally held in a support whereby the frictional contact between the marker and tire will cause the marker to move in the direction of movement of the tire in an arcuate path that carries it away from the tire. The marker solenoid is operated by a very simple relay circuit activated by a signal from the tire uniformity machine.

Title: Free piston engine ignition apparatus
IPC: F02P5/15
Filed: 1971-08-23
Abstract: Apparatus and method features are disclosed for initiating combustion in free piston engines in response to a movement-related characteristic of the power piston, such as its rate of change of position in the power cylinder of the engine, so that combustion is caused to occur at a desired time which is related to the time the power piston reverses direction at the start of a power stroke, without regard to variations from one stroke to another in the actual physical position of the power piston along its path of movement in the power cylinder at the moment of piston reversal. Various means are shown or suggested for sensing piston movement and causing combustion in response to changes in the velocity or acceleration of such piston movement at a controlled time interval before or after such velocity drops to zero or after such velocity has reached a maximum, i.e., at or near the moment when the piston reaches its inner dead point in the power cylinder, and preferably somewhat before that moment.

Title: Yarn-twisting method and apparatus
IPC: D02G3/36
Filed: 1975-03-26
Abstract: Method and apparatus for manufacturing yarn. The yarn has a flexible core at least part of which is twisted in a given direction while surface fibers are carried by the core at least at the twisted part thereof and are helically wound onto the exterior surface of the core in a direction opposite from the direction of twist thereof where the surface fibers are located. The yarn core initially has the fibers projecting laterally therefrom, and then the yarn core is false twisted while the fibers are helically wound into engagement with the exterior surface of the core when the initial twist is introduced into the same during false twisting with the helical winding of the fibers being in a direction opposite to the direction of the twist introduced into the core by false twisting thereof. The false twisting of the core is brought about by a simple rotary member which surrounds the core and is rotated with respect thereto at a speed sufficiently great to provide substantial slippage between the rotary member and the core, this rotary member having an end surface which engages the fibers and winds them helically against the exterior surface of the core during longitudinal feeding of the latter through the rotary member, with this action on the fibers resulting in the false twisting of the core.
