Abstract: A rolling-type bellows for vehicular pneumatic cushioning systems. In the installed state, support surfaces of the bellows that are adjacent to the end beads thereof are supported against vehicle parts that are movable relative to one another; the axial width of the support surfaces can vary. In the region of the annular support surfaces, the bellows are provided with raised interval axial ribs, which enhance the buckle-free continuous movement of the rolling folds, and reduces wear of the walls of the bellows.

Abstract: A method and oven equipment for cooling a charge after thermal treatment. The charge, which is located within a closed chamber, is cooled by blowing in cooling gas. The cooling occurs as a function of the actual conditions of the charge at a predetermined speed, and a uniform distribution of temperature within the charge is assured. For this purpose, the temperature distribution in the charge is measured by temperature sensors, and the intensity and/or direction of the flow of the cooling gas can be changed if deviations from the predetermined theoretical values occur. The wall of the closed treatment chamber of the oven equipment contains a plurality of gas passages which can either be closed off, or are permeable for gases yet impermeable for heat rays. Cooling gases are conducted through the chamber via control valves. The cooling gas is circulated with the aid of a blower unit along with a gas cooler.

Abstract: The build-up drum of build-up machines is frequently interchangeably mounted on its drive shaft in order to be able to adapt to changes in dimension in the production program with one and the same machine. If the operating and control elements associated with the drum bear directly against the end walls of the drum, each change of the drum requires considerable expense for adjustments and alignments. This is avoided by providing the build-up drum on both sides with a respective spacer and abutment sleeve against which the movable operating and control elements can bear in a constantly uniform orientation relative to the middle of the drum as the critical reference plane.

Abstract: An apparatus for reducing the size of, and/or for mixing, solid, pasty and/or liquid material. The apparatus includes a cylindrical housing in which is disposed at least one grinding roller, which cooperates with the inner surface of the housing. Each grinding roller is mounted between two bearing disks in such a way as to be rotatable about its central axis and eccentrically relative to the central axis of the housing. The bearing disks in turn are rotatably driven about the central axis of the housing. In order to enable the grinding rollers to execute the necessary deflection movements, and to avoid over stressing the bearings or supports for the grinding rollers, both end faces of each grinding roller are provided with an axle end that is guided, with play, between two drive wheels that are rotatably mounted on the bearing disks. When the bearing disks rotate, the drive wheels rotatably drive the grinding rollers, which are pressed by centrifugal force against the inner surface of the housing.

Abstract: A fuel injection system for self-ignition internal combustion engines. At least part of the connecting line leading from the injection pump to the injection valve includes two circuits of different lengths which are connected in parallel in order to obtain a pre-injection phase and a main injection phase. In order to accurately set the fuel quantity for pre-injection, and the time interval relative to main injection or, respectively, the timing of the two fuel injections, and to make them independent of the level and the time characteristic of the pump pressure, i.e., ultimately independent of the speed and load of the engine, a special metering valve unit is provided in the shorter circuit of the divided connecting circuit, and a check valve unit is provided in the longer circuit at the end of the latter. Furthermore, the ratio of the diameter of the fuel line leading to the injection device, including the shorter circuit, to the diameter of the longer circuit (time-delay circuit) is between 1 and 2.

Abstract: A method and vacuum furnace for heat-treating a charge. Pursuant to the method, after the charge is placed in the receiving vessel, the latter is evacuated and flooded with inert gas. Subsequently, the charge is heated to the maximum permissible operating temperature of the circulation device by heating and gas circulation. Thereafter, the charge is heated to the desired end temperature by static inert gas or under vacuum, and essentially by radiation heat. The vacuum furnace may include a steel vessel which can be closed off, and which contains an inner heating chamber for receiving the charge. A heating device is provided within the heating chamber, and a fan and a gas guiding arrangement are provided for producing a gas circulation through the heating chamber. In the second phase, in which the heating is effected by radiant heat, the heating chamber can be closed off, accompanied by disconnection of the fan. For this purpose, an opening is provided in the wall of the heating chamber.

Abstract: A rotary disk filter element for a beverage filter for biological filtration. The filter element includes a closed base plate that is in the form of a ring-like member and on which is supported a filter fabric, with a support fabric being interposed between the base plate and the filter fabric. The filter fabric is secured to the base plate between an outwardly disposed retaining member and an inwardly disposed collar member. The collar member is provided with a supply opening for a wash fluid, especially a water/air mixture that is flushed through the filter fabric, counter to the direction of filtration, for removing filter residue for the general cleaning of the filter fabric. The filter fabric is secured to the base plate and to the support fabric at a plurality of point locations. This divides the free support or clamping lengths of the filter fabric into a number of relatively short regions that prevent the filter fabric from being overstretched and bulged during flushing.

Abstract: An arrangement for converting a multi-track stream of bottles to a single-track stream of bottles. An intermediate conveyer is disposed between a feeding mechanism, which is provided with guide rails, and a withdrawal mechanism, which is provided with guide rails. The upper sides of the conveyer belts of the intermediate conveyer form a conversion region in which the conveyer belts are disposed flushly adjacent one another in the shape of an inclined plane which is inclined transverse to the direction in which bottles are conveyed from the upper side of the feeding mechanism to the upper side of the withdrawal mechanism. The conversion region is formed by the upper sides of the conveyer belts of the intermediate conveyer and of the withdrawal mechanism. The track width of the conversion region corresponds to the track width of the heating mechanism, with the conversion region being disposed downstream of the feeding mechanism and essentially coinciding in level and track with the latter.

Abstract: An ink supply system for writing instruments which operate with liquid ink. The writing instrument has a large-volume ink reservoir which communicates via a recharge valve with a small-volume ink reservoir which is adjacent to the writing element. The transmission of ink from the large-volume ink reservoir to the secondary reservoir is controlled by a sensor as a function of the quantity of ink which is present in the secondary ink reservoir. In order to simplify the recharging of the ink, and to be able to operate with the least possible electrical energy, the present invention utilizes as a recharge valve a tube pump which is rotatably driven by an electric motor and also can generate the pressure necessary to convey the ink to the secondary ink reservoir.

The steam inlet is disposed at one end face of the pressure tank. Drying steam leaves the water separator, one end of which is supplied with wet steam, and enters the pressure tank.

Abstract: A tire pressure regulating unit for modifying the air pressure in vehicle tires while traveling. Shutters, which are arranged between the tire and the tire control valve, have parallel-connected auxiliary valves which release an additional passage cross-section when the regulation pressure decreases. The shutters may also be provided on the other side of the tire control valve in the work line in the region of the wheel hub, with rapid release valves being connected in parallel to the shutters and permitting bleeding to the atmosphere upon a decrease of regulation pressure. In this way short bleeding times are achieved even for low regulation pressures.

Abstract: To convey corrosive liquids, rubber hoses are customarily provided with an inner lining that is made of a synthetic material which is resistant to solvent. In order to achieve the previously unobtainable smooth, fold-free application of the thin plastic foil against the inner rubber layer of a hose, the present invention utilizes an extremely thin-walled contractible foil sleeve that is smoothly contracted upon a rigid fabrication mandrel. This foil sleeve then forms the base for the further build-up of the hose.
