Date Sep. 8, 1989.In a multi-axis mechanical manipulator with adjustable travel and protection against overloading. The movement is transmitted to the indexing mechanism (10) by the combination of a sliding rotor motor (2) of a reducing gear with wheel and endless screw (30) and an adjustable torque limiter (40). The law of motion of the indexing mechanism (10) is determined in this way so as to obtain constant speed over a wide range, possibly with stopping points. The rotating frame (56) is linked to the indexing mechanism (10) by a spring bushing (50). The movement is transmitted to the cylindrical cam (6) by an adjustable torque limiter (28). The manipulating arm (7) is displaced by a spring plate which permits a momentary angular retraction of the arm (7) when it encounters an obstacle. The present invention may be used for the handling of loads or parts.

Title: Cable-controlled electrical safety switch device
Inventor: PICCOLI JEAN-LUC
IPC: H01H3/02
Filed: 1989-03-22
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE            A cable-controlled electrical safety switch device comprises a piston 15 tensioning a cable 2 under the action of a spring 23 via a rod 10 and a screw thread 12a for adjusting the tension of the spring and of the cable. A piston groove 25 actuates a push member 28 for the switch 40. The piston is angularly adjustable. The flank 32 of the groove remote from the spring is helicoidal. When the cable is long, a higher tension is selected so that the groove flank 31 moves away from the push member 28. This distancing is desirable in order that any  length variations due to heat - which are greater with a long cable -may be prevented from triggering the switch. The clearance between the other flank 32 and the push member 28 is then corrected by rotation of the piston.

Abstract: ABSTRACT OF THE INVENTION     The  invention  concerns  a process  and  an  apparatus  for  the production of hollow bodies from thermoplastic material, the wall of which is in the form of a laminate,  by means of extrusion blow molding.  Tubular preforms for making the hollow bodies are first produced in an intermittent mode of operation, the wall thereof also being in the form of a laminate comprising a suitable number of layers. Within an extrusion head having an annular storage chamber for receiving the laminate-formation preform and an annular piston for emptying the storage chamber, the flows of material for forming the layers of the laminate of the preform are passed through the annular piston into the storage chamber in which they combine to form the laminate. The width of the outlets at which the flows of material issue  from  the  annular piston  can  be  so  selected  that  it  is proportional to the thickness of the respective layers to be formed therefrom in the laminate produced in the storage chamber.

Abstract: ABSTRACT OF THE DISCLOSURE        A mobile station comprises a receiver for receiving a signal from the base station and a transmitter including a frequency synthesizer, a modulator and a power amplifier connected to it. For power savings purposes, the transmitter is deactivated during a standby mode. If an earlier portion of a signal received from the base station indicates a likelihood of a need to return an acknowledgment, power is supplied to the frequency synthesizer to allow it to stabilize in advance. If a later portion of the received signal indicate that there actually exists the need to acknowledge the receipt of the signal, the power amplifier is subsequently activated and an acknowledgment signal is returned through it to the base station. If the later portion of the received signal indicates the absence of the need to acknowledge, the frequency synthesizer is again deactivated and the power amplifier remains deactivated.

Abstract: ABSTRACT OF THE DISCLOSURE       A modular concrete-block form which is shaped in a rectangular configuration and has a pair of oppositely disposed side panel members and end enclosed panels to define a body cavity to receive poured concrete therein.  The side panels are held in a fixed parallel relation to each other and are further prevented from side-to-side movement relative to each other by a plurality of strut members which are fixedly mounted transversely from one side panel to the other.  The unique arrangement of the strut members contributes to a very stable block framework.  Each strut member is formed with substantially "H"-shaped tenon members that are slidably engaged with spaced-apart, "T"-shaped slots formed in the inner surfaces of said side panels.  The panel structure is firmly grasped within the pair of opposed stud members that define the tenons.  The tenons are integrally connected together by means of truss members that further define passages therethrough for flow of wet concrete therebetween.
