Title: Conveyor system
IPC: B61G1/00
Filed: 1988-04-18
Granted: 1992-09-02
Abstract: A known overhead conveyor system has a multiplicity of transport units (6) which can be displaced on rollers (8) and whose end faces are in each case provided with hooks (9, 9a) of identical design. The hooks (9, 9a) are arranged in such a way that they can couple two transport units (6) together when they engage round one another. However, the rigid fastening of the hooks only permits a coupling when a transport unit (6) is swivelled out. If the transport unit is swivelled out unintentionally, for example during overrunning while negotiating a curve, there is a danger of uncoupling. 
<??>By contrast, the new conveyor system can also be operated with overrunning during curve travel (31) without uncoupling taking place. This is achieved in that the hooks (9, 9a) are mounted swivellably about an axis of rotation (12) and encompass a locking part (10b) in each case arranged on the opposite transport unit. 
<??>The invention can be applied in particular to overhead conveyor systems.

Granted: 1992-08-26
Abstract: The invention relates to a process for the preparation of polychlorophosphazene. According to this process the molecular mass of the polymers is adjusted at will by performing the reaction of the polycondensation of N(dichlorophosphoryl)trichlorophosphazene in the presence of the product of reaction of such a monomer with an organic alkali metal salt.

Title: Railroad superstructure
IPC: E01B3/00
Filed: 1988-01-27
Granted: 1991-12-11
Abstract: For a railroad superstructure, consisting of a solid bearing layer and, arranged thereon, a track framework consisting of ties and rails, it is proposed to arrange a soft, elastomeric gas-filled compensation film, which does not adhere to the bearing layer, between the surface of the solid bearing layer and tie underside. With a rough surface, the support of the ties is thus increased and at the same time the tie is mounted in a vibration-damping and noise-damping manner. Track position corrections are possible without destroying the previously usual bitumen/asphalt/adhesive material; the track framework installation can also take place in wet and frosty weather. The positional fixing of the track framework can take place by means of positive anchoring.

Abstract: An improved sensor for dissolved oxygen measurement comprising a body having an electrolyte reservoir and electrolyte contained therein and an opening for communication between the exterior of the body and the reservoir and an anode and cathode concentrically disposed in the body adjacent the opening. A thin polymeric membrane permeable to oxygen and impermeable to the electrolyte seals the opening. The working surfaces of the anode and cathode, that is the surfaces adjacent the membrane, are spaced apart from the membrane to define an electrolyte space between the working surfaces and the membrane. A noble metal screen is disposed on the working surface of the anode. Preferably the screen completely covers the anode working surface and a portion of the screen which would normally overlie the working surface of the cathode is cut away so that the cathode working surface is unobstructed. The noble metal screen over the anode surface results in a substantial retention of electrode stability over a period of time as compared to sensors similarly constructed but which do not include the noble metal screen over the anode working surface.

Abstract: An improved circuit board material having a support layer, an electrical resistance layer and a conductive layer. The circuit board material has a resistance of at least about 500 ohms/square. The circuit board material is formed by electro-plating the electrical resistance layer on the conductive layer. The conductive layer is desirably activated prior to electro-deposition of the electrical resistance layer thereon. The conductive layer is activated by contacting with an activating agent such as benzotriazole electrolytic chromate and the like. A preferred electro-plating bath for electro-deposition of the electrical resistance layer comprises about 0.5 mole per liters nickel hypophosphite. The disclosed electro-plating bath functions at ambient temperatures and is effectively temperature independent. Circuit boards can be formed from the circuit board material through a process involving only two etching steps.
