Abstract: A neck rod member for stringed instruments, particularly for bass guitars. The rod member includes two oblong rod portions which extend parallel relative to each other and essentially contact one another. At one end of the rod member, the portions are fixedly connected to each other, for example, by rivets. At the other free ends of the rod portions, a mechanism for effectively shortening the length of one of the rod portions relative to the effective length of the other rod portion is provided. The neck of the instrument defines an oblong blind-end hole which is open at the free end of the neck. The rod member can be inserted into the blind-end hole in such a way that the mechanism for shortening the effective length of the first rod portion is accessible from the open end of the blind-end bore. The neck rod member includes another mechanism for shortening the effective length of the second rod portion relative to the effective length of the first rod portion. This second mechanism is also accessible from the open end of the blind-end hole.

Filed: 1987-12-22
Granted: 1994-07-16
Abstract: The invention describes a method and apparatus for the acoustic signalling of cases of drowning in swimming pools, to guarantee reliable trigger of the alarm while avoiding any false alarms. This is effected basically by a switching element (1) in a water-tight encapsulation, which is disposed beneath the surface of the water and which, in the event of an alarm, triggers a first alarm device (2) and delivers an acoustic signal via a signal horn (5). A transmitter (6) is also connected to the alarm device (2) and transmits the alarm signal to a receiver at a distance and to another alarm device (10). Instead of the switching element (1), a microphone (12) can advantageously be used for cases in which the swimming pool water is frozen.

Abstract: A coin separator/rejector system includes a plurality of coin races which are disposed in a compact coin receiver body. The races have at least one protrusion along their length so as to deflect downwardly traveling coins and force these coins to alter both their attitude and direction of travel to encounter apertures formed in the receiver body between successive coin races. Coins of a selected diameter travel downwardly along any given coin race for ultimate deposit or credit. Coins of less than the selected diameter are directed into an alternate direction and path of travel along an alternate or secondary race where they are either credited or rejected.

Abstract: In a hydraulic control device for the drive control of a double-acting hydraulic cylinder with a relatively large driving face and a relatively small counterface on its driving piston, a direction- and- motion-control valve is provided in the form of a follow-up control valve which operates with electrically controllable desired position value stipulation and mechanical actual position value feedback. The pressure supply unit provides two supply pressures PN and PH of different magnitude. A pressure-controlled pressure changeover valve is provided which switches over to high supply pressure as required if the load increases. Also provided is a face changeover valve, likewise pressure-controlled, which, after the pressure changeover valve has switched over to higher supply pressure, switches over from differential operation of the hydraulic cylinder to pressurisation on one side of its piston, on the larger piston face of the latter, or, if the requirement for propulsive force has decreased again, after the pressure changeover valve has for this reason switched back to lower supply pressure, for its part switches back to differential operation of the hydraulic cylinder.
