Abstract: A hydraulic dashpot or shock absorber for motor vehicles. It comprises a cylinder and a piston. The cylinder contains fluid. The piston travels back and forth inside the cylinder on the end of a piston rod. The rod extends through a package of gaskets that maintains it aligned and seals the cylinder. The rod is attached to the vehicle body or wheel assembly by a projecting-bolt joint. The joint (5) includes resiliently yielding components that suppress impact and vibration by way of an automatic snap-together attachment to the vehicle body or wheel assembly. The projecting-bolt joint (5) is provided with at least one spring (6). The spring snaps into a matching (bent) rigid part of the vehicle body or wheel assembly. Spacers are associated with the resiliently yielding components that suppress impact and vibration. The spacers restrict their deformation once they have been installed.

Abstract: A spiral housing with a spiral cross-section for a turbomachine, in which a disk diffuser with an upstream annular disk space is asymmetrical to the spiral cross-section. This spiral cross-section has a base circle of substantially constant diameter. The spiral cross-section also has a tongue region and a region adjacent to the tongue with circular spiral cross-sections extending to where an outside diameter of the spiral cross-section equals a specific diameter and the circular spiral cross-sections continue thereafter to increase in cross-section only axially.

Abstract: The invention concerns a regulable shock-absorption valve system for the dashpot in a motor vehicle. It has two shock-absorption valves. Each valve consists of an electromagnetic bolt that slides back and forth and operates in conjunction with at least one port and of a pressure-sensitive valve for the suction stage and for the compression stage, mutually coaxially accommodated in an essentially cylindrical housing and capable of communicating by way of hydraulic-fluid channels. The pressure-sensitive valves (7 & 8) in accordance with the present invention rest on a simple or complex component (15) with its ends permanently or temporarily secured in a bore that extends through the center of the pole cores (17 & 18) of the electromagnets (11) that actuate the bolts (5 & 6). The advantages of the present invention are direct transmission of the shock-absorption forces and simpler assembly of the system.

Abstract: A continuous-operation cargo-transfer equipment. It comprises bulk-cargo uptake mechanisms (4a), an upright conveyor-constituted shaft (4), a boom (5) with a conveyor mounted on it that seesaws up and down on a turntable (6), a gantry (10) that travels back and forth on a pontoon (2), intermediate belts (6b & 6c), and a tender-loading conveyor belt (16) that operates in conjunction with a bulk-goods expulsion spout (17) on a pivoting and displacing beam (12). Such equipment is employed outside ports for transferring bulk cargo from deep-draft ocean-going vessels to shallow-draft tenders. The object is to maintain the cargo-uptake point inside the deep-draft vessel (1) as steady as possible. The equipment is provided with two Counterweights (7 & 15). One counterweight (7) compensates for any listing that occurs when the boom wanders out of position. The other counterweight (15) compensates for any listing that accompanies the sweep of the tender-loading conveyor belt (16).

Connections are provided for hydraulic fluid to move the cylinders. These connections are provided on the hollow piston rod and the long-stroke cylinder for admitting fluid to move the hollow-piston cylinder and the long-stroke cylinder.

Abstract: A pliers-like tool for twisting the partly stripped end of the multiple-strand core of an insulated conductor, characterized by projections 41 and 42 extending out of the free end of each jaw 121 & 131 and toward the other jaw into the space between them, whereby the projections follow the arc described by the opening and closing jaws, the projections are not coplanar, and space is accordingly left between them, one of the projections is long enough to overlap the other to a limited extent when the jaws are separated, and the surfaces of the jaws that demarcate the space between them are high-friction. The conductor is cut to length, insulation is stripped from the end of the core to a limited extent, the end of the core is twisted between the high-friction surfaces, and a connector is extracted from a belt and crimped around the twisted end, all by the same tool.

Abstract: An arrangement for operating an arc furnace with two vessels for making steel. Enough liquid raw iron is added to account for 70% of the total starting metallurgicals. The supply of electricity to one of the vessels is discontinued but not to the other vessel. The injection of oxygen through a lance accompanied by the addition of sponge or coolant and lime, is carried out in one vessel while an electric-arc furnace phase is carried out in the other vessel, whereby additional sponge or coolant is melted with less oxygen and additional lime or coal is added. Electrodes are mounted on an arm and can be pivoted over either vessel as desired.

One embodiment includes a two-layer strip with two halves sewn together along the edge of an incision. This strip can be inserted as a whole or with only one half between the sections of the shaft. In the later event the second half of the strip will overlap the outside of the edge of the lower section of the shaft.

Abstract: An arrangement for steering the laser beam, in an active optical triangulation method based on three-dimensional sensors, along paths which are sensitive to the context of the scene of interest, and alleviating the need to undergo a search path by the sensor. A conventional video camera is used to preview the scene of interest and the resultant intensity image is processed to locate the desired path based on the scene context. The sensory system is modeled to enable determination of the instantaneous angular deflections of the laser beam along with the translation of the laser source that can shift the nominal or actual data acquisition path to the desired data acquisition path.

Abstract: A device for discontinuously advancing stock or work along or in discontinuously operating production machinery, a press for example. The stock or work is gripped by grips distributed along parallel and separated rails. The grip-supporting rails extend in the direction the stock or work advances in. The rails have three different motions, specifically back and forth together in the direction the stock or work moves in, together and apart transversely at at least one essentially right angle to that direction, and up and down together. A separate drive mechanism discontinuously governs each motion. The separate drive mechanisms are positioned essentially symmetrical to and below the rails. The drive that moves the grip-supporting rails together and apart accommodates at least one spindle that is engaged by a motor. The drive that moves the rails up and down accommodates at least one spindle that is engaged by another motor.

The channels may be proportional to a selected keystone pattern, and the channels may be rectangular-shaped and accommodate keystoning effects of an imaged beam.

Abstract: A device for ensuring safety by preventing mechanically raised and lowered components, roll-up gates for example, from crashing down when the motor or transmission fails. The device is characterized by a friction clutch. The friction clutch comprises a stationary half and a moving half. The stationary half is secured to the shaft inside a housing. The moving half is mounted on a base and can be electromagnetically displaced axially in relation to the base and against the stationary half. The force exerted by the moving half against the stationary half is augmented by resilient components that engage between the housing and the moving-half base.
