Patent DE-3366212-D1 (DE)
Title: Protection circuit for a switching transistor
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H03K17/08
Filed: 1983-04-20
Granted: 1986-10-23
Abstract: A protective circuit for a switching transistor is disclosed in which the base-emitter voltage of the switching transistor is compared in a comparator with a reference voltage. If the collector current of the switching transistor increases, the base-emitter voltage also increases, with the base current remaining constant. As soon as the base-emitter voltage exceeds the reference voltage, a signal is delivered at the output of the comparator. A switching-off device for switching off the driving pulses of the switching transistor responds to this signal so that a switching-on pulse present at the base of the switching transistor is switched off. The reference voltage is fixed so that the switching transistor is protected against overload by excessively large collector currents.

Granted: 1987-04-09
Abstract: A covering ring for a vehicle wheel. The bead seating surfaces of a tire are mounted on the radially inner periphery of the rim. In order to prevent dirt and/or water from entering the space between the tire bead and the rim well, the covering ring has a width which covers the space between the tire bead, that portion of the rim which extends axially outwardly from the rim well, and the rim well. Also provision is made that the radially inner surface of the covering ring, when viewed in the transverse direction, extends horizontally or is laterally inclined toward the outside. Also provision is made that the radially inner diameter of the covering ring at no point of the space, which is to be covered, be greater than the radially inner diameter of the mounted tire in the bead region.

Inventor: NORBERG GEORG BENZEL
IPC: B29C65/74
Filed: 1983-05-25
Granted: 1987-05-14
Abstract: The invention relates to plastic pockets to be applied to parcels and the like and intended to contain address labels, packing lists and the like, and which are provided with an adhesive on one side to be applied to the parcel. According to the invention, the plastic pockets are formed from two plastic films which are welded together with a bottom weld (1) and two lateral welds (2, 3), which do not reach up to the openings of the pockets so that a section (5) is formed where the films are not welded together. The pockets are applied to a protective paper in the form of a continuous web and are separated by perforations (6) which only penetrate the plastic films but not the protective paper. The invention also relates to a device for dispensing plastic pockets according to the above and comprising a holder (10) for a roll (11) of a web of a number of plastic pockets on a continuous protective paper and means (14) for opening the pockets for introduction of dispatch notes and/or other communications. In a preferred embodiment the feed of the web of pockets is driven and is controlled by sensor means (13) so that the opening is correctly carried out.

Inventor: MIKKELSEN HENRIK
IPC: A23G9/26
Filed: 1983-09-09
Granted: 1989-07-20
Abstract: A bag (1) for use in the shaping of liquid food products or stimulants consists of two plastics foils (2, 3), which are welded together in such an area of the two foils as will provide a plurality of interconnected mould cavities (4) with a common inlet (5). In the mould cavities (4) there are placed sticks (6) which are held in position by the positioning in a channel (8) having a length and cross-section corresponding to the holding part (7) of the stick (6). When the bag is filled with liquid ice cream or a similar material, the mould cavities (4) are distended three-dimensionally, and when the length of the sticks (6) is suitably dimensioned with respect to the length of the mould cavities (4), the sticks will be firmly "fixed" within the mould cavities (4). The sticks (6) are therefore placed in the middle of the ice lollies formed after freezing.

Abstract: An apparatus and method for on-line monitoring of a characteristic of a process liquid stream includes a cell for isolating a precise volume of the liquid. There are provided means for over-filling a sample chamber and means for removing the excess from the chamber comprising a downwardly extending drain line which terminates at a precisely positioned, downwardly facing inlet and means for applying negative pressure to the drain line to draw the excess liquid upwardly from the captured volume until the liquid level reaches the inlet and entry of air disrupts the liquid draining effect. The embodiment shown employs a closed volume, a vent, a conduit for delivery of process liquid into the cell under pressure and a syphon/drain line for removing excess liquid from the cell volume until there remains only a sample of accurately repeatable volume.

Abstract: A vehicle load monitoring system for a tipping vehicle is disclosed which both provides the driver with useful information during loading to enable him to ensure compliance with legal limits on certain load parameters, and checks on various vehicle variables before or during tipping to inhibit the occurrence of situations in which the vehicle may become unstable, e.g. when parked on an incline. On loading, measured load weight components are corrected in accordance with a detected longitudinal (front-to-back) vehicle inclination and calculated load parameters are compared with thresholds which have been predetermined in accordance with the legal restrictions. In unloading, the position of the centre of gravity of the load is calculated and longitudinal and lateral load inclinations are detected, and the locus of the centre of gravity during tipping is predicted. If it is determined that the predicted locus will cause a condition of vehicle instability, tipping or further tipping is inhibited and an alarm given. Additionally or alternatively, prediction of unstable conditions can be carried out before tipping commences, and/or a dangerous situation due to shifting load can be detected during tipping.

Abstract: There is disclosed an improvement in a surface maintenance machine (16) whereby means are provided for automatically maintaining a desired normal force by a maintenance tool (30, 32) against a surface being maintained, although there may be undulations in the surface, variations in the condition of the surface and changes in the tool caused by wear. Normal force is applied to the tool by gravity and an actuator (54), both acting through a load cell (44) which senses their algebraic sum, compares this with a preset desired force and operates the actuator as needed to maintain the force at or near the pre-set level. Further, the load on the motor or motors (34, 36) driving the tool is sensed and compared against high and low reference points. If drive motor load is outside of the reference limits a signal is provided which causes a decrease or increase in the normal force to maintain the motor load within limits.
