IPC: G01M7/02
Filed: 1982-11-09
Abstract: In order to provide spikes and dips in the frequency response of a random vibrations testing device comprising a noise generator (1), the output thereof is connected to an input of a wide-band filter (2). An output of the wide-band filter (2) is connected directly and through paralleled narrow-band in- phase signal shaping channels to a means (3) serving to shape spikes and dips in a shaped signal spectrum and coupled electrically with narrow-band opposite-phase signal shaping channels. The means (3) for shaping spikes and dips in the shaped signal spectrum is devised in the form of an adder (12) connected in series to the wide-band filter (2), used by all the narrow-band in-phase signal shaping channel and serving to shape spikes in the shaped signal spectrum, and adders (13) also series-connected to the above- mentioned wide-band filter, used individually by each narrow-band opposite-phase signal shaping channel and serving to shape dips in the shaped signal spectrum. <IMAGE>

Title: Centrifugal cleaning of used mineral oils
Inventor: TENTHOFF ALOYS
IPC: B04B1/14
Filed: 1984-04-10
Abstract: In a process for centrifugal cleaning of used mineral oils, the solids - liquid mixture is fed to a centrifugal drum (1) by means of a central inlet (2). Solids and water are collected in the solids zone (5) of the drum and the cleaned oil is removed from the central area of the drum by means of a first discharge pipe (9) and a smaller partial oil flow is removed from the peripheral area of the drum by means of passages (7) and a second discharge pipe (10) and is returned to the inlet (2). As soon as the water level in the centrifugal drum reaches the start of the passages (7), water flows in the second discharge pipe (10). This is detected by a conductivity meter (12) located in the second discharge pipe and brings about the switching over of a changeover valve (11) also located in said pipe, so that the return to the inlet is interrupted. <IMAGE>

Patent GB-841097-A (GB)
Abstract: 841,097. Controlling nuclear reactors. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 14, 1958 [Feb. 26, 1957], No. 4886/58. Class 39(4). [Also in Groups XXX and XXXVIII] The control rod of a nuclear reactor is attached to a lead screw 66 which is moved axially by a driving mechanism 64, which in turn is operated by an electric motor comprising stator 60 and rotor 62. Engagement is controlled by an electromagnet 72 which operates a latching member 70 co-operating with pivoted arms 68. The position of the rod is indicated electrically by variation of the inductance of coils 20 as the rod moves in or out of the member 76, these coils having their axes at an angle (90 degrees as shown) to the field produced by the electromagnet 72 (see Group XXXVIII). Adjusting screws 81 enable the indication to be set to zero when the rod is in a datum position.
Patent GB-2159837-A (GB)
Title: Tin free steel
Inventor: SHIMIZU NOBUYOSHI
IPC: C25D5/12
Filed: 1984-06-07
Abstract: Tin free steel has a steel base and three layers consisting of a bottom layer of metallic chromium, a middle layer of nickel-zinc alloy containing e.g. 10 to 90 weight percent of zinc and a top layer of hydrated chromium oxide. A method for the continuous production of this tin free steel comprises: a) chromium plating a steel base to form a layer of metallic chromium and hydrated chromium oxide, b) nickel-zinc alloy plating the chromium plated steel base by using a nickel-zinc alloy plating electrolyte sufficiently acidic to dissolve the hydrated chromium oxide and c) forming a hydrated chromium oxide layer on the chromium plated nickel-zinc plated steel base. Instead of b) in the above method, a cathodic treatment in an acidic solution can be carried out for the removal of hydrated chromium oxide formed during chromium plating, and thereafter nickel-zinc alloy plating can be carried out by using a known nickel-zinc alloy plating electrolyte. This tin free steel is useful for producing welded can bodies at high speed without removing the plated layer in the welded part, since it has an excellent weldability.

Patent GB-2154329-A (GB)
Title: Power metering system and method
Inventor: ROBINTON MICHAEL ALAN
IPC: G01R21/133
Filed: 1984-07-24
Abstract: The metering system and method provides an electronic power meter for simultaneously producing digital pulse trains proportional to power and to VARS or Q. In the preferred embodiment, the metering system employs delta-minus-sigma modulation of the voltage signal which produces a modulated output signal used for gating the analog current signal, multiplying voltage and current. The product of voltage and current is then supplied to another delta-minus-sigma modulator (90), which serves as a convertor outputting a pulse train. The converter (90) produces separate pulse trains for each polarity of the power being measured. VARS or Q readings are produced by delaying the output of the modulator (30) by a selected amount to produce the necessary voltage lag, after which the delayed modulated signal is supplied to another multiplying gate. A second converter (90) is used to output VARS and Q. A metering method is also disclosed, as well as an offset compensation system (70, C1) for use with metering systems.

Title: Nestable luggage trolley
Inventor: WANZL RUDOLF
IPC: B62B5/00
Filed: 1986-06-10
Abstract: Luggage vehicles are known which, pushed together into a stack, can only be shunted when an in each case rear luggage vehicle slightly lifts a part of the luggage vehicle which in each case is in the front. Only then are the automatic brakes of this vehicle eased. A disadvantage is the high expenditure of force which has to be produced when the luggage vehicles are to be pushed inside one another. To achieve this, the invention proposes a manually movable luggage vehicle (1) in which a substantial part of its platform (18) is designed as a cantilever extending in the direction of travel; in which, moreover, openings (29) are provided at the lower ends of the hollow columns (11) in which openings (29) is guided a transverse bar (28), which traverses the distance between the hollow columns (11), and is connected to the brake rods (15), and in which stops (30) are provided between the platform (18) and the chassis frame (4), which stops (30) are intended for deflecting the transverse bar (28) of a luggage vehicle (1') in front, the wheels thereof remaining on the ground, but the brakes being released by the deflection of the bar. <IMAGE>

Patent GB-2187002-A (GB)
Title: Power drive
Inventor: LINTON DAVID J
IPC: F04B49/10
Filed: 1987-02-06
Abstract: A power drive unit has a hydraulic motor 10 for use in controlling bi-directional movement of a member which can operate with either an opposing load or an aiding load. The power drive unit has a variable displacement hydraulic motor 10 and a control valve 45 for controlling the connection of the motor to the supply and return lines. During operation of the motor with an opposing load, a first electrohydraulic servo valve 70 controls the position of a wobbler 22 of the motor to have the motor output torque match the load torque to achieve the desired speed and, with a relatively low opposing load with the motor at minimum displacement, a second electrohydraulic servo valve 90 controls the position of the control valve 45 to reduce the pressure differential across the motor for further reduction in the motor output torque to achieve the desired speed. When there is an aiding load, the motor is still at minimum displacement and the control valve throttles the flow to create a highly negative pressure differential to provide the necessary braking effect on the motor with a relatively low flow through the motor whereby the quantity of fluid throttled is minimized and the generation of heat resulting from the throttling is minimized. A control circuit Figure 2 or 3, (not shown) uses motor output speed to actuate the valve 45 or the wobbler 22 depending on the direction of the load. <IMAGE>
