It furthermore relates to their use as medicaments for the treatment of diseases which can be treated with growth hormone and to methods of treatment. It also relates to methods of application of such polymeric human growth hormone prodrug or pharmaceutical formulation.

Abstract: Provided herein are antibodies, such as immunoglobulins Y (IgY) antibodies that inhibit beta-lactamase activity, e.g., TEM-1 beta-lactamase, as well as related compositions and methods of use thereof to treat infections by lactam-based antibiotic bacteria that produce beta-lactamase that can degrade antibiotics.

Abstract: The invention relates to a method for producing high purity 1,2-dichloroethane using a liquid reaction medium that is circulated and that is essentially composed of 1,2-dichloroethane and a catalyst. At least ethylene and chlorine are added to the reaction medium and a mainly chlorine-containing gas flow is dissolved in a part of the reaction medium which is essentially devoid of dissolved ethylene. The gaseous components not dissolved in this solution are removed from the solution by means of a gas-separation device and the solution from which the undissolved gas components were removed is contacted with ethylene which is present in dissolved form.

Abstract: In order to transfer data via a switched network that provides a wide range of network services, the users must establish a circuit or network connection and establish a data link connection. The circuit or network connection provides the physical connection between the users and data link connection provides the protocols and procedures for the transfer of data. Because the network provides a wide range of services, the users, typically by prior agreement, designate a common data link protocol to facilitate the transfer of data. A data link connection will not be established if the users are not using the same data link protocol. A method and apparatus are disclosed which permit a local system to detect the data link protocol used by a remote system. The invention provides a method for detecting the data link protocol used by the remote system when the remote system initiates the data link setup and a method for detecting the data link protocol when the local system initiates the data link setup.

Abstract: This invention relates to an electrode positioning mechanism of an electric, electric arc or reduction furnace, in particular for smelting steel, with a guide column, having a mast arm to hold the electrode and guided in a guide frame by front and lateral guide rollers, which are located in a nest, and which can be moved vertically, whereby there are mechanical damping elements to damp mechanical vibrations. To create an electrode positioning mechanism which uses simple means to achieve a vibrational isolation of the individual components of the electrode positioning mechanism, and which reduces the breakage of electrodes in comparison to the devices of the prior art which use complex damping means, the invention proposes that the damping elements 14 be located between the front and lateral guide rollers 6 and the guide frame 7.

Abstract: A measuring head for a vacuum gauge. An essentially cylindrical housing encloses a measuring cell which is sealed in a vacuum tight manner against the surrounding atmosphere and is connectable with an evacuatable cavity. A measuring filament for producing an electrical signal corresponding to the pressure in the measuring cell is disposed in the measuring cell. The measuring filament is disposed approximately perpendicularly to the axial direction of the housing.

Abstract: In a circuit for an ionization vacuum gauge having a thermionic filament, a control circuit receptive of a control current for controlling the filament and a switch for applying the control current to the control circuit, a circuit is provided for indicating a filament interruption independent of the state of the switch. The circuit includes at least one resistor by-passing the switch to provide a continuous sensing current to the filament and a detector for detecting the interruption in the sensing current and for indicating such an interruption.

Abstract: A cluster of pins, serving to clean the surface of a workpiece, are slidably mounted in bores of a guide plate which is spring-urged against a metallic anvil, with formation of a clearance between the plate and the anvil in which the heads of the pins can move. The anvil is periodically struck by a ram which is freely reciprocable in a tool housing surrounding the anvil and the guide plate, the housing being provided with a pistol grip carrying a trigger that controls admission of compressed air to a chamber at the rear of the housing which is intermittently vented by the advancing ram to a space communicating with the atmosphere via channels in the anvil and perforations of the guide plate, thereby cooling the movable parts of the tool. The guide plate consists of a hard but light-weight resinous material, specifically polyamide 6.

Abstract: A switchboard booth structure having a unique arrangement of exteriorly accessible service and control devices and interiorly accessible switch devices for controlling low voltage elements of electrical apparatus, particularly metallurgic electric furnaces is disclosed herein.

Abstract: A method is provided for lengthening the life of electric arc furnace linings in the production of steel from scrap, while at the same time introducing sponge iron pellets to shorten the melting time. This is achieved by predetermining the increase in power at the arc-molten bath interface upon introduction of the sponge iron and automatically reducing the power factor in the circuits feeding the electrodes according to the predetermination, upon each introduction of sponge iron.
