Title: Device for detecting pulsed laser radiation
Inventor: DIETRICH KLAUS DIPL PHYS DR
IPC: G01J3/51
Filed: 1982-08-20
Abstract: The device for detecting pulsed laser radiation has at least a first and a second radiation detector and respectively a first and second filter connected upstream of the radiation detectors, the first filter and the second filters being respectively transparent in one or more narrow-band spectral region(s) of the laser radiation. The second filter is opaque in the spectral regions in which the first filter(s) is/are transparent, and transparent in narrow-band spectral regions closely adjacent thereto. The spectral regions for the transparency of the first and second filters each have approximately the same bandwidth. The light pulses from lasers can be distinguished from other light pulses by forming the difference between the intensity of radiation received by the second and by a first radiation detector (1, 2). <IMAGE>

Title: Tilting stand for a metallurgical vessel
Inventor: DRAB ERNST
IPC: B22D41/06
Filed: 1982-10-12
Abstract: In the case of a tilting stand for a metallurgical vessel (3), having two aligned tilting journals (8; 8') supporting a supporting arrangement (12, 13; 12', 13') for the metallurgical vessel, the supporting arrangement can be pivoted about the axis (11) of the tilting journals and at least one (8') of the tilting journals (8; 8') is connected to a tilting drive (9). In order to ensure that the metallurgical vessel (3) rests in a completely satisfactory manner on the supporting arrangement, even when the metallurgical vessel (3) no longer has the original geometrical shape, and in order to be able to minimise the driving power for the tilting drive (9), the supporting arrangement comprises two opposite receivers (12, 13; 12', 13') and one receiver is assigned to each of the tilting journals (8; 8') and can be pivoted about the axis (11) of the tilting journals (8; 8') independently of the second receiver, it being possible to connect the metallurgical vessel (3) to the receivers (12, 13; 12', 13') to form one unit. <IMAGE>

Title: Pressure control device
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/26
Filed: 1983-01-21
Abstract: The invention proceeds from a pressure control device (5) with an inlet chamber (4) connected to a pressure source (1) and an outlet chamber (21) connected to at least one rear wheel brake (24). A first valve piston (10) is exposed to the pressure of the inlet chamber (4) for controlling a valve passage (20, 23) between the inlet chamber (4) and the outlet chamber (21). The first valve piston (10) is carried sealed in the housing (6) and displaceable against a control force. The pressure control device (5) also has a second valve piston (14) by means of which the pressure in the outlet chamber (21) can be controlled when the valve passage (20, 23) is in the closed position, the valve pistons (10, 14) being partially carried inside one another. With a view to improved control of the valve pistons (10, 14) and an improved sealing of the valve passage (20, 23) it is proposed that in the first valve piston (10) a pressure medium duct (20), which can be shut off by a valve closing element (23) formed on the second valve piston (14), be provided by means of which the inlet chamber (4) and the outlet chamber (21) are normally hydraulically connected to one another. <IMAGE>

Patent DE-3310241-A1 (DE)
Title: Filter network with a second-degree transmission function
Inventor: FRANK ERWIN-THOMAS DIPL ING
IPC: H04B1/62
Filed: 1983-03-22
Abstract: An active RC circuit is used for a filter network with a second-degree transmission function which can be approximated very closely to predefined pre-emphasis and de-emphasis characteristics. A T-network (R1, R2, C1) is located in the negative feedback arm of an amplifier stage (V1) for the pre-emphasis circuit. This T-network is bypassed by an RC series circuit (R0, C0). A corresponding T-network (R1', R2', C2') is connected upstream of an amplifier stage (V2) for the de-emphasis circuit. This T-network is also bypassed by an RC series circuit (R0', C0'). The filter network can be adapted to the predefined characteristic by means of two balancing elements (R0, R2; R0', R2') in each case (Fig. 1 and 2). <IMAGE>

Patent DE-3324485-A1 (DE)
Title: Machine suitable for use as a gear motor or a gear pump
Inventor: PRUNER JOSEF
IPC: F01C1/12
Filed: 1983-07-07
Abstract: The invention relates to a machine suitable for use as a gear motor or a gear pump for gaseous or liquid media with at least one meshing first gear in which, by virtue of new design measures, an essentially higher motor power is obtained without any significant increase in the required space, the weight or the fuel demand, if used as a gear motor, and an essential increase in the pump output without any increase in the required space or the weight when used as a gear pump. In this connection, each of the two intermeshing gears of the gear pair is designed in such a way that the upper part of each of the two teeth projects radially beyond the pitch circle and a depression provided for accommodation of that part of the tooth of the other gear projecting beyond the pitch circle is arranged directly next to this in the direction of the circumference. In this connection, rollers, which form an at least approximately tight barrier for the medium such as air, oil and the like serving for operation, are arranged in an axial direction next to the two gears and rigidly connected to these. The shafts of the gear pair are coupled to one another by an additional gear pair which is toothed over the entire circumference or by some other suitable means. <IMAGE>

Title: Twin drum for drying or calcining and cooling loose material
Inventor: SCHAEFER LOTHAR DIPL ING
IPC: B01J6/00
Filed: 1983-07-09
Abstract: In the known twin drums for drying, calcining and cooling, the inner drum (4) is arranged rotationally solidly in a rotatably mounted outer drum (1) by means of sliding supports. The loose material then emerges from the end face (9) of the inner drum (4) and flows back into the outer drum, the sliding supports being located in the flow path. The supports are thus ground down by the coarse granular loose material and reduced in their cross-section within a very short time to such an extent that they must be replaced. To avoid this, the inner drum (4) is extended approximately up to the end of the outer drum (1) and mounted for longitudinal displacement by means of a bearing (6), located in its central axis, on an extension of the axis of the inner drum (5). In addition, the outlet (12) for the loose material is located on the side wall (13) of the inner drum (4). The bearing points for the inner drum (4) are thus located outside the stream of loose material, so that any wear is eliminated. <IMAGE>

Title: Additional device for cigarette packs
IPC: A24F15/12
Filed: 1983-08-16
Abstract: Soft cigarette packs have the disadvantage that they cannot always be completely closed again after the tin foil wrapper has been opened. As a consequence, the cigarettes become desiccated, tobacco crumbs fall out and some cigarettes may crumble. The invention provides a remedy by means of an additional device for cigarette packs, consisting of a wire frame with two arms intended to engage into the wrapping and connected to each other by a web which bears a plate intended for laying on the closure surface of the cigarette pack, extending approximately over two thirds of the width and over the complete thickness of the cigarette pack, and adjoined by a lid which extends over the remaining portion of the width of the cigarette pack. The arms intended to engage in the wrapping expediently have an outward curvature to enable them to bear with an appropriate prestress after being inserted into the wrapping of the cigarette pack.
Patent DE-3331663-A1 (DE)
Title: Spring strut for a vehicle, especially for a motor cycle
Inventor: AXTHAMMER LUDWIG DIPL ING
IPC: B60G17/08
Filed: 1983-09-02
Abstract: For a spring strut for a vehicle, especially for a motor cycle, it is in many cases desirable that the spring characteristic be variable as a function of the rate of compression and/or the compression travel. A variation of the spring characteristic during the braking process is desirable especially in the case of motor cycles in order largely to avoid dipping of the telescopic fork. In the case of spring struts which comprise an inner and an outer tube, which are carried so as to be axially movably and sealed off inside one another like a telescope and define an internal chamber filled with damping liquid and gas, at least one spring being arranged in this internal chamber, a variation of the spring characteristic as a function of one control variable is simply achieved in that in the inner tube carried in the outer tube an axially movable separating element is arranged in the area of the damping liquid filling, which element subdivides the internal chamber into two working chambers and that these working chambers can be connected to one another by way of a passage cross section arranged in the separating element and/or interacting with the separating element.
