Patent DE-3503462-A1 (DE)
Title: Device for adjusting play
Inventor: BERG ARTHUR A
IPC: F16D65/50
Filed: 1985-02-01
Abstract: The invention relates to a device for adjusting play for the transport sector, the device having a main body with a lever arm formed integrally at one end. Formed in the main body is an opening in which is accommodated a worm wheel mounted on a brake-actuating shaft. Formed in the main body, adjoining the opening, is a slot which has three adjoining and mutually perpendicular faces of one size and shape by means of which a worm can be fixed and held in engagement with the worm wheel. Also arranged in the main body is a bore which extends essentially perpendicular to one of the mutually adjoining faces of the slot. Accommodated in the bore is a shaft which carries the worm coaxially and supports it for the purpose of adjustment. The bore is overdimensioned in relation to the shaft and, as a result, the shaft does not require any support in it. A torque exerted on the worm wheel by the lever arm of the main body produces a resultant force parallel to the longitudinal axis of the worm and this force is transmitted by the worm to one of the faces of the slot.

Title: Method for the controlled variation of a temperature gradient in a substrate while holding constant a prescribable mean temperature
Inventor: KLUGE-WEISS PETRA DR
IPC: G05D23/20
Filed: 1985-02-20
Abstract: In this method, the temperature (T) and its gradient (dT/dx) are set by means of thermal radiation which is generated by two heatable surfaces (3, 4) arranged on two mutually opposite sides of the substrate (1). Furthermore, the mean temperature (T) of the substrate is measured and fed as actual value (TI) in addition to a prescribable desired value (TS) to a controller (10) whose output signal (TR) is used to control the heating power of the two heatable surfaces (3, 4) and, in addition, is amplified separately for each heatable surface (3, 4) by a weighting factor (G1, G2) assigned to the respective surface (3, 4). A previously produced calibration graph or a calibration table are used, taking account of the desired value (TS) of the mean temperature (T) relating to the respectively prescribed instantaneous value (dT/dx(t)) of the temperature gradient (dT/dx), to determine the weighting factors (G1, G2). <IMAGE>

Title: Intake system for a vehicle internal combustion engine
Inventor: SEUFER THEO DIPL ING
IPC: F02D11/08
Filed: 1985-08-29
Abstract: In an intake system for an internal combustion engine for driving a vehicle by way of a disengageable clutch and a gear box a first throttle valve 2, actuatable by an accelerator pedal 3, is arranged in the intake line 1 and downstream of this a second throttle valve 5, which is acted upon in the opening direction by a spring 6 and is connected to the diaphragm 8 of a pressure load cell 7 with two chambers 12, 13, of which the first chamber 12 is ventilated and the second chamber 13 is connected to the intake line 1 downstream of the first throttle valve 2 by a line 14 with a restricted cross-section 15, so that, on opening of the first throttle valve 2, the second throttle valve 5 at first frees the intake cross-section gradually. This delayed release of the intake cross-section, however, is not desirable when the accelerator pedal 3 is fully depressed in order to obtain the maximum possible acceleration, nor when changing gear, for which reason the chamber 13 is connected to the intake line 1 upstream of the first throttle valve 2 by a line 17 with a valve 19, which when the accelerator pedal 3 is fully depressed and the clutch pedal 20 is fully depressed is opened, so that the chamber 13 is ventilated and the second throttle valve 5 is immediately swivelled into its open position by the spring 6. <IMAGE>

Title: Device for laminating both sides of carrier panels with associated cutting device
IPC: H05K3/00
Filed: 1985-11-11
Abstract: In a device for laminating both sides of carrier panels with plastic films and a cutting device for cutting off the film, the device for laminating consists of an intake device on which the carrier panels to be coated with the film on both sides are laid with mutual, short spacings at their ends, after which the carrier panels are then transported into the roll nip between two opposite laminating rolls and are there coated on both sides with the continuous length of film. In order to cut off the overhang of film flush with the end at the successive carrier panels, the cutting device consists of a blade beam which is movable perpendicularly to the surface of the carrier panel and has a multiplicity of cutters, the cutting edges of which extend parallel to the transport direction and the width of which corresponds approximately to the end spacing between two successive carrier panels.
Patent DE-3543607-A1 (DE)
Title: High-accuracy weighing machine as a beam scale with arms of equal length
Inventor: SPEIDEL KARL ING GRAD
IPC: G01G5/02
Filed: 1985-12-10
Abstract: The high-accuracy weighing machine according to the invention is a beam scale with arms of equal length, in which known hydrostatic laws are consistently used to determine weights when masses are relatively small. One advantage in particular of this principle is that it permits determination of extremely small changes in mass, such as those which occur during drying. If a cylindrical submersible body of a known cross section is partially suspended in an immersion vessel containing a liquid of known density, the weight of the submersible body is reduced by the weight of the liquid displaced. The apparent weight of the submersible body is reduced in a linear fashion as the depth of immersion increases. If an indifferently mounted balance beam is loaded with the submersible body on one side and a weighing scale of a comparable mass on the other side, a stable equilibrium is reached when a certain depth of immersion has been reached. A small addition to the mass on the weighing scale results in a new equilibrium at a shallower depth of immersion. Lowering the immersion vessel permits the balance beam to return to its original horizontal position; the weight of the additional mass can be calculated from the lowering distance.
Patent DE-3545513-A1 (DE)
Title: Luminaire frame
Inventor: DECKER MATHIAS
IPC: F21V15/02
Filed: 1985-12-20
Abstract: Fastening the profiled strips (11, 12) to a corner piece (14) of a luminaire frame is performed exclusively by lugs (15) of the profiled strips. These lugs (15) are bent around the walls of the limbs (17) on the corner piece (14) and recessed into depressions (19). Each lug (15) has a rear sloping edge (15a) which interacts with a clamping surface (20) of the depression (19) when the face end of the profiled strip abuts a stop (21) of the corner piece (14). A rattle-free and firm connection between the profiled strip and corner piece is achieved in this way. The corner piece has a channel (23) which is free from any projecting parts, with the result that leads can be guided through without hindrance.

Title: Vibrating classifier
Inventor: KAUFMANN HANS
IPC: B03B4/00
Filed: 1986-01-31
Abstract: The vibrating classifier for classifying lumpy solids having different densities, such as for example coal and refuse material, into light and heavy material comprises a case (1) which receives the material to be classified at one end, is mounted so as to be capable of vibrating and, in a working position, is inclined towards the discharge end. Located in the interior of the case (1) is an air-permeable jig bed (7), through which air can be introduced into the material being treated. An output channel (9) for heavy material, which is positioned transversely and is open at the bottom adjoins the discharge-side end of the jig bed (7), the outlet opening (10) of the output channel being closed by a sluice, for example a cellular wheel sluice (11). Provided above the output channel (9) is a vertically adjustable overflow (12) for the outlet of the light material. Furthermore, attached to the case (1), preferably on its upper side, are two unbalance drivers (6) contrarotating in equal phase, for example vibration motors, the axes of rotation of which run in a plane parallel to the plane of the case. A linear vibration is generated here, which causes the case (1) to vibrate harmonically up and down over its whole length. With the aid of the cellular wheel sluice (11) at the output channel (9) for the heavy material, the output of the heavy material can be controlled in accordance with the respective conditions. In this case the treated material can also be charged discontinuously. <IMAGE>
