Abstract: The following invention relates to a locking clip (1), specifically a geometric friction device for securing cord-like materials (3), particularly a locking clip for securing a length of resilient rubber cord, yet more specifically for providing a means of attaching resilient rubber cords to furniture items to convert said furniture items into resistance training apparatus for the purpose rehabilitation or fitness training. The locking clip comprising a housing (2) which comprises a plurality of chambers, providing means for forming a fixing loop (4), and a locking chamber (12), wherein said at least one locking chamber is located at an acute angle (a) to at least one of the plurality of chambers.

Abstract: The removal or transport of cut-off catch selvages in a loom is monitored by one or more sensors which produce a sensor output signal that represents the actual movement of the cut-off catch selvage. The sensor output signal is processed in an evaluation processor for producing a fault signal if and when the sensor output signal deviates from a predetermined standard or reference signal. The fault signal is used to trigger an alarm and/or stop the loom.

Abstract: A device for operating a weaving loom, including at least one carrier rail (5) which extends along a large portion of the weaving loom width and on which at least one operating device (1) can be arbitrarily moved. The device also includes structures for the wireless and/or wire-dependent voltage supply to the operating device (1), and for the signal transmission of control commands to the weaving loom control system. An alternative embodiment consists of constructing the operating device (1) as a portable remote operating unit (11) which has devices for the wireless signal transmission of control commands to the weaving loom control system.

Abstract: A pneumatically operable injection device has a first pressure cylinder with a piston which is adapted to be rigidly but detachably connected to a piston of an injection syringe, and a second pressure cylinder with a piston having an extension adapted to co-operate with a three-way cock in such a manner as to cause the three-way cock to be operated by movement of its piston. Flow connections are provided between the outlet of the injection syringe and the three-way cock, between the three-way cock and a connecting piece, and between the three-way cock and an inlet of a reservoir for the substance to be injected. The device is adapted to effect either a connection between the outlet of the injection syringe and the connecting piece or between the syringe outlet and the reservoir. Compressed-air lines are provided for the purpose of pneumatically operating the pistons in the two pressure cylinders.
