Patent DE-3339264-A1 (DE)
Inventor: MCCRACKEN DAVID R
IPC: G01R31/319
Filed: 1983-10-28
Abstract: A special purpose pulse amplifier with programmable high and low levels for complex IC testing is disclosed. Its output has independently programmable positive and negative transition rates and is reverse terminated in 50 ohms. It also has the ability to be switched to a high resistance, low capacitance output state. This circuit is the interface between a complex, computer controlled system of timing and pattern generation hardware, and an integrated circuit to be tested. This device has reduced waveform aberrations, lower inhibited capacitance, low input to output delay for reducing timing error, programmable signal transition rates, and the amplitude range and transition rate control to accommodate all the important device technologies expected in high pin-count parts.
Patent DE-3340810-A1 (DE)
Title: Process for producing prismatic components of reinforced concrete, in particular reinforced concrete supports, and an apparatus for carrying out the process
IPC: E04G13/02
Filed: 1983-11-11
Abstract: In the production of reinforced concrete supports, a closed tube (2) made of plastic, smooth-walled at least on the inside, is used as formwork (1). After heating-induced widening in the sense of a circumferential enlargement, the said tube is drawn off in the longitudinal direction of the support with the aid of lifting tackle acting on jack rings (4). The heat of hydration of the setting concrete is sometimes sufficient for the widening of the tube; for heating, however, the tube may also be subjected to heat, for example in the form of hot air, steam, electric energy or the like. <IMAGE>
Patent DE-3343099-A1 (DE)
IPC: H02B13/02
Filed: 1983-11-29
Abstract: An electrical, medium voltage, switching mechanism which includes a casing having an insulating material filling. In the casing, between a cable connection and a bus bar, a change-over switch, which can alternately switch between a phase contact and a ground contact, follows a load disconnector which is in the form of a vacuum switching tube. An axially displaceable shaft is provided which is displaceable relative to the load disconnector and is rotatable relative to the change-over switch. The bus bar passes through an insulator at right angles thereto. The associated through passage in the insulator is widened into a slot, the length of which permits the switching movements of the load disconnector. The insulator is divided into an insulator core and an insulator casing which is rotatably mounted on the insulator core. In the region of the insulator casing, the through passage is further widened into two sector windows which have an angular aperture which permits the switching movements of the rotary contact of the change-over switch. As a result, the switching mechanism has a structural form which at high operational reliability requires little space, is economical to manufacture, and can be serviced in a time saving manner.

Title: Circuit for protecting loudspeakers against overload
Inventor: SCHULZ-DUSENSCHOEN HOLGER
IPC: H04R3/00
Filed: 1984-06-01
Abstract: The invention relates to a circuit for protecting loudspeakers against overload in which the audio-frequency voltage arriving from an amplifier is usually fed to the loudspeaker via the normally-closed contact of a relay which is set to a first switching position. A DC voltage obtained from the audio-frequency voltage by rectification is applied to the winding of the relay and, in the event of overload, sets the relay to its second switching position in which the loudspeaker is deactivated as soon as the voltage exceeds a predetermined critical value. A polarised relay is used which can be switched from the second back to the first switching position by the application of a DC reset voltage.

Patent DE-3422742-A1 (DE)
Inventor: MICHEL HORST WERNER
IPC: B22C9/12
Filed: 1984-06-19
Abstract: An apparatus for hardening cores and/or molds made of sand with the addition of hardenable binding agents, which are used for casting molded bodies from flowable substances, is described, whereby an amount, predetermined by metering devices controlled via control valves, of the substance which causes the binding agent to harden is introduced into the core or mold by aid of compressed air the rate of flow of which is regulatable by a regulating valve, whereby this substance is mixed with this compressed air, and the regulating valve is automatically controlled according to a predetermined schedule. The apparatus can be carried out with considerably fewer components and the necessary control means can in particular be designed much more simply if, according to one embodiment, the regulating valve is controlled by means of a proportional pressure regulating valve which is operated by an external control means which also controls the other control valves. As an alternative to this, the regulating valve can be controlled, according to a second embodiment, via a preadjustable pressure regulating valve and a directional valve which is controlled electrically or pneumatically.

Title: Arrangement for treating irrigation water enriched with CO2 and H2CO3
Inventor: KUECKENS ALEXANDER
IPC: B01F3/04
Filed: 1984-09-04
Abstract: An improved arrangement for the bubble-free tapping of irrigation water highly enriched with CO2 and H2CO3 is provided by means of which, even at high flow velocities and high delivery pressures, the occurrence of bubbles in the irrigation water can be prevented. This is achieved by carrying out the impregnation at a pressure substantially lower than the transport pressure and thus avoiding the production of unbound bubbles, and any bubbles which nevertheless occur can, by rapid absorption in non-impregnated water, likewise be physically bound to the irrigation water.
Patent DE-3439418-A1 (DE)
Title: Pipe clamp
IPC: F16L3/10

Abstract: The invention relates to a pipe clamp having an annular clamp body whose inside is covered by means of a rubber-elastic insert and whose ends bound a closable opening, the one end pointing outwards and being provided with a holder for a closing screw, while a connecting body which holds the closing screw is supported in the other end such that it can pivot. Such a pipe clamp is also intended to be capable of being fitted easily using only one hand. This is achieved in that the connecting body is constructed as an angled piece whose one limb is arranged on the outside of the clamp body and whose other limb is arranged on the inside of the clamp body, and is covered by the insert, the angle between the limbs being selected such that the outer limb runs approximately parallel to the end of the clamp body pointing outwards, when the pipe clamp is in the closed position, and the inner limb rests approximately over the entire area against the inside of the clamp body. Preferred field of application: sanitary and electrical installation.   <IMAGE>

Title: Sprung electrical contact arrangement

Abstract: The sprung contact pins and/or contact sockets for electrical single-pin or multi-pin plugs having insulating contact pin and contact socket holders (2) which can also be used as a handle, and having electrical output leads from the contact elements, are distinguished by the fact that the contact pin (1) is bent in the manner of a wavy line and is twisted about its longitudinal axis, as elastic spring means, and/or the contact socket (20) is constructed in a helical shape over a part of the length such that the part which is formed like a wave or is helical is capable of elongation, and the external diameter (D) of the wavy contact pin region (1) is larger than the internal diameter of an associated plug socket, or the internal diameter (B) of the contact socket helix (20) is smaller than the external diameter of the wavy region of an associated contact pin. If the radial pressure increases, the wavy region of the contact pin can expand in the axial direction so that the contact pressure remains essentially constant within a relatively large clamping width of the socket geometry. The contact is self-cleaning; any dirt which accumulates can be displaced onto depositing points on the wavy pin region without interfering with the spring or contact characteristics. <IMAGE>
