Patent DE-3714511-A1 (DE)
Inventor: MOLLENDORF FRIEDRICH WILHELM
IPC: H02J7/10
Filed: 1987-04-30
Abstract: The potential across a secondary electrochemical power storage cell 14, 16 is monitored by a comparator 22 in a protective device 10 and a transistor 54 is turned on when the voltage across the cell rises to a predetermined value whereby charging current to the cell is bypassed through transistor 54. Thereafter transistor 54 turns off and on repeatedly in response to the fall and rise of cell voltage thus producing a chopping effect on the charging current so that the cell is trickle charged. Each cell of a battery of cells, charged in series, may have a respective protective device 10 so that all cells can be substantially fully charged. The devices 10 may be part of the charger or part of the battery, and the charger may provide a constant, or limited, charging current and may stop charging when the voltage across the series of cells rises to a predetermined value. The comparator 22 also operates an indicator 58 by means of a transistor 56 which may provide a digital signal to a computer which monitors the states of charge of individual cells and calculates a desirable charging current. The cells may have sodium anodes, Fe/FeCl2 active cathodes, and N or AlCl4 electrolyte. <IMAGE>

Title: Parking disc
Inventor: SCHAEPERTOENS MARTIN
IPC: G07C1/30
Filed: 1987-05-14
Abstract: A parking disc for use in a motor vehicle contains a disc-shaped basic body with a window. A display device for displaying a time is arranged behind the window. This display device can be advanced by a clock. This advancing operation can be optionally interrupted and restarted as the clock continues to work. During this restarting, the display device is synchronised with the clock. When a motor vehicle is parked, the advancing of the display device has only to be interrupted, as a result of which the arrival time is automatically permanently displayed. After returning, the user can restart the advancing. After synchronisation, the display device then runs again at the right time.

Title: Labelling apparatus
Inventor: KUEPPERSBUSCH GERD
IPC: B65C9/20
Filed: 1987-09-02
Abstract: The problem arises in the labelling of containers that either cheap labels can be used, in which case the application and fastening of the labels on the containers is difficult, or application is simple, in which case labels are expensive. An apparatus which can apply cost-effective labels to containers cheaply, permanently and with a good appearance is to be provided. A labelling apparatus for applying labels to product containers (23) has a feed device (12) for the feeding of labels. It possesses, furthermore, a device for feeding a foil (3), adhesive on one side, to the product container (23) in such a way that the adhesive side faces the container (23). The labelling feed device (12) applies one label at a time onto the adhesive side of the foil (3) in front of the container (23). A cutting device (21) cuts off the foil (3) as a function of the label size, so that an edge projecting beyond the label is formed. A labelling apparatus of this type is particularly suitable for the labelling of cans and similar containers. <IMAGE>

Patent DE-3803597-A1 (DE)
Inventor: HORNUNG FRIEDRICH DIPL ING
IPC: H02K11/25
Filed: 1988-02-06
Abstract: Device for measuring temperatures and rotational speeds of rotating parts, in particular shafts of electric machines such as motors and generators. Marks (2) which change in function of the temperature are placed on a shaft (4). A fixed sensor (1) reacts to the changes of the marks and emits a voltage pulse from which the temperature and the rotational speed can be derived. The marks may consist of liquid stripes (2) or ferrite (13) whose colour or magnetism (e.g. Curie temperature) change at a given temperature. It is also proposed to mount a simple sensor (5, 12) whose position or sensitivity of measurement vary with temperature and which derives the temperature and rotational speed from the arrangement of fixed geometric marks on the shaft. The measurements are made without contact and require only a sensor.

Title: Process for the underground connection of a product pipe to a collector, in particular in the region in which it is not possible to walk
Inventor: UFFMANN HANS-PETER DR ING
IPC: E03F3/06
Filed: 1988-02-19
Abstract: In a process for the underground connection of a product pipe 5 to a collector 2, in particular in the region in which it is not possible to walk, in the case of which process, by using a protective casing 1, a bore 4 is first of all provided in the earth, into which bore the product pipe 5 is then introduced, a core bore 3 for the product pipe 5 is bored into the collector 2 once the bore 4 has been provided in the earth. Said core bore 3 serves to centre the front end 23, which is then to be introduced into it, of the product pipe 5. In order to carry out the process, there are provided, on a guide rod 6, two centring devices 10, 15, of which one 10 is located in the front region of the product pipe 5 and fixes the guide rod 6 in the product pipe 5 in a centred manner. The second, front centring device 15 is located essentially in front of the product pipe 5. It has bearing shells 15 which come to lie in the core bore 3 and can be radially spread apart onto the diameter of the core bore 3. The centring of the front end of the guide rod 6 in the core bore 3 also results in a corresponding centring of the front end of the product pipe 5 in relation to the core bore 3. In this centred position, an advancement of the product pipe 5 results in a reliable introduction of its front end 23 into the core bore 3, where sealing can then be carried out. <IMAGE>

Title: Alternative cigarette without tobacco or nicotine, having an independently ignitable, finely flavoured smouldering zone and an individual inhalation zone
Inventor: WELLHAUSEN ANNA
IPC: A24D1/22
Filed: 1988-08-08
Abstract: The smoking ritual corresponds to a normal cigarette length; the smouldering zone is ultimately stubbed out as usual in the ashtray. The illusion is not only externally complete. The "no regrets" pleasure of smoking is suitable for communication and identification with smokers and for offering a smoke to one another without a guilty conscience. The dependence and health risk of chain-smoking are avoided, but the social and not insignificant pyschological aspect - the fascination of fire and smoke from an archaic human heritage - are taken into account. As a result, the change over and de-habituation from conventional tobacco smoking is easier to achieve. This is (externally, both cigarette and pipe forms are possible) a new generation in the health-conscious smoking ritual; a responsibly rounded stimulant for senses and nerves.

Title: Steel honeycomb heating segments for boilers
Inventor: ROEHNER ERNST
IPC: F23C13/00
Filed: 1988-08-22
Abstract: There are hundreds of designs of boiler which all aim to achieve the best possible heating capacity. The more recent boilers have already obtained fairly good heating capacities but have not yet reached that of the invention. In the last few years, a renowned firm has produced, after a long series of experiments, a steel honeycomb heating segment which is intended as a catalytic converter for cars and thus has achieved high-quality results. This steel honeycomb heating segment is tailor-made for the boiler combustion chamber, since it becomes white hot in a few seconds and splits up, from the start, even the hardly combustible oil particles and burns them completely. A first-class and environmentally friendly heat output is thus achieved.
Patent DE-3828562-A1 (DE)
Title: Transmitted-light projector
IPC: G03B21/00
Filed: 1988-08-23
Abstract: The invention relates to a transmitted-light projector, consisting of a light source, a condenser, a slide stage, and an objective (lens). It is the object of the invention to create a transmitted-light projector which is suitable in particular for the projection of LCDs and which is distinguished by the fact that when the distance of the projector from the projection screen is altered it is no longer necessary to alter the position in terms of height of the projected picture so that, by means of this projector, pictures can be projected without distortion onto horizontal projection screens independently of the size of the projected picture area. The invention consists in that the lower edge ray in the optical beam path which runs through the upper part of the condenser and the upper edge of the picture to be projected and ends in the lower edge of the picture projected is arranged horizontally or approximately horizontally and that the condenser is arranged at an acute angle with respect to the slide stage.

Filed: 1988-09-09
Abstract: A microtome with a drive device is described, which has a shaft and a handwheel, arranged thereupon, with a grip. For locking the drive device, an electromagnet is firmly arranged on the housing frame of the microtome. The latter is in effective connection with an indexing ring, axially displaceable on the shaft. A control device, which is electrically connected to the electromagnet and to a sensor, controls the electromagnet in response to a signal of the sensor. The sensor triggers the signal by the position of an indexing ring arranged axially displaceably on the shaft. The said indexing ring is movable in frictional connection with a pin arranged in the grip and axially displaceable by means of a lever. The lever is actuated by seizing of the grip and the locking of the drive device is cancelled.
