Patent DE-3800307-A1 (DE)
Inventor: HASENBEIN NORBERT DR
IPC: C09J123/04
Filed: 1988-01-08
Abstract: A process for grafting ethylenically unsaturated carboxylic acids and/or carboxylic anhydrides onto polyolefin mixtures in which the polyolefin mixture comprises from 5 to 49 parts by weight of an ethylene/propylene block copolymer having an ethylene content of less than or equal to 20 % by weight, and from 51 to 95 parts by weight of a homopolymer or copolymer of ethylene. The graft copolymer mixtures obtained are used as coupling agents (adhesion promoters), in particular in composites comprising polyethylene/coupling agent/steel, and for the preparation of ionomers.

Title: Tension or compression bar for connecting two concrete parts
Inventor: WITSCHI HEINZ
IPC: E21D20/02
Filed: 1988-01-16
Abstract: The tension or compression bar (1) consists of corrosive steel. It exhibits a sleeve (3) which is manufactured from non-corrosive material, is pushed over the bar (1) and, upon installation into the separating region (B), comes to lie between the two elements (P) which are to be connected. The interspace between sleeve and bar is filled with a pourable, hardening material. The connection according to the invention permits the use of relatively thin reinforcing steel, while having constant stability in the separating region (B). Furthermore, the connection, in the separating region (B) is protected against corrosion without the entire tension or compression bar consisting of expensive, stainless steel. <IMAGE>

Title: Use of alkaline porous support materials for dry separation of pollutant gas with increase of moisture
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/50
Filed: 1988-02-06
Abstract: In the process for dry separation of pollutant gas by the use of calcium silicate hydrates, high pollutant gas sorption is achieved if the sorbent contains sufficient moisture. By addition of water to the intensive mixture mentioned in Patent Application P 3733208.2, the required moisture can be established. By controlling the addition of water and flow rate of the solids mass stream, the purification effect of the dry sorption plant can be controlled in such a way that it corresponds to the required clean gas values.

Title: Method for measuring acceleration
Inventor: FREITAG ROLF
IPC: G01P15/08
Filed: 1988-05-25
Abstract: Although technical accelerometers display low acceleration and small changes in acceleration, they mostly have a high inertia. This novel method can be sensitive and can be applied in the case of very fast changes in acceleration, such as in gravity waves. In the event of acceleration (5), the electrons in metal and other conductors (1) such as superconductors, semiconductors and the like are clearly displaced. Since this is less the case for other conductors (ion conductors) (2), the charge displacement, e.g. can thus be measured with the aid of a femto voltmeter (3). Since the plasma of explosions by nuclear explosives exhibits this displacement only during ignition and thereafter loads the displacement in the casing of the nuclear explosive charge, the explosion can be evaluated thereby. Acceleration measurement and measurement of explosions of nuclear explosives.     6 = force of an electron due to weight 7 = counterforce due to the electric field as a result of the displacement of electrons in the conductor having a relatively high electron mobility UA = voltage across the ends of a conductor having a relatively high electron mobility which are situated in the direction of acceleration (approximately).   <IMAGE>

Patent DE-3827575-A1 (DE)
Title: Holding device, in particular for erecting and supporting a Christmas tree
Inventor: WALTER WOLFGANG
IPC: A47G33/12
Filed: 1988-08-13
Abstract: Christmas trees are usually set up by means of special tree stands. For this purpose, the tree is tapered at its lower end and fixed in a holding device of the stand by means of screws. The disadvantages of this are in particular that the arrangement of tree and stand topples over very easily and that by tapering the end of the trunk the water supply to the tree is no longer guaranteed. The new holding device is to avoid these disadvantages. The new holding device (1) is characterised in that it has a cord holder (2) which can be suspended from the head (7) of a screw (11) screwed into a room ceiling (10) and can be connected by means of a cord (3) to the top of the tree. Advantageously, the dead weight of the tree ensures an upright position, thereby eliminating any risk of toppling over. Since the tapering of the end of the trunk can be dispensed with, the full trunk area, in particular the bark area, is available to take up water from any desired storage vessel placed underneath at a suitable height. The holding device is suitable in particular for supporting a Christmas tree, but also an advent wreath, an Easter branch or the like. <IMAGE>

Title: Device for controlling the contact force for current collectors
Inventor: SCHOELLER ROLAND
IPC: B60L5/28
Filed: 1988-09-13
Abstract: Device for controlling the contact force exerted by the current collector of an electric tractive unit on the contact wire by means of a lifting device. In the force transmission path of the current collector (2, 4, 5) one or more threshold value switches (9, 10) are arranged which serve as force sensors and together trigger an actuation of the lifting device with the effect of increasing the contact force for stresses which lie below the threshold values of the said switches (9, 10). Two force-transmitting components (4, 2) of the current collector serve in each case as threshold value switches and are connected to one another in a sprung fashion and are arranged displaceably with respect to one another when under load, one (4, 6) of these components bearing the ends (7, 8) of a cut-open optical waveguide (9) between which a shutter (10) which is connected to the other component (2) projects, the said shutter (10) clearing the light path when the load value drops below the prescribed threshold value, as a result of which an optical sensor which is arranged at the end of the light path is triggered. <IMAGE>

Title: Parking building of a steel-skeleton grid-type construction
Inventor: DUSOER WERNER
IPC: E04H6/22
Filed: 1989-03-02
Abstract: Parking building of a multistorey steel-skeleton grid-type construction, characterised in that the storeys are designed to be approximately 2 1/2 times the height of any passenger car and, by horizontal transportation of the vehicles, parked on pallets, over passenger cars which have already been parked, cars can be parked on virtually the full surface area of the individual levels. Depending on size and frequency of use, each of the storeys is assigned one or more lifting shafts for vertical lifting, by means of lifting and shifting gear, as far as the upper region of the storey height. The electrically equipped rail-guiding system provided with electronic control means runs beneath the web-like grid connections of the respectively top storey level. In the case of small installations which do not have a high vehicle turnover, only one lifting shaft reaches up to roof level, equipped with an additional load-bearing frame (spindle drive, hydraulics, chains or the like) which advances the lifting gear embedded therein, together with pallet and passenger car, up to the respective storey rail system for transfer purposes.

Title: Method for starting and carrying out a controlled radio operation for avoiding collisions between vehicles
Inventor: GOETTING JUN HANS-HEINRICH DIP
IPC: G08G1/16
Filed: 1989-05-11
Abstract: Methods are known for avoiding collisions, in which the vehicles involved identify themselves by repeatedly transmitting signals. The distance between the vehicles is determined either by the received field strength at the respectively following vehicle or by comparing the transmitted location data. Transmitter synchronism is problematic. When two vehicles travelling one behind the other transmit and receive simultaneously, they cannot identify each other.   Transmitter synchronism is reduced by changing the transmission and receiving times. The times depend on the speed of the vehicles. Slower vehicles transmit for a longer time and/or have shorter receiving times. So that collisions can be avoided even when the speed measurement is faulty, the times can additionally be changed in a statistically random manner. The method is suitable for assisting the driver or for automatic operation of driverless vehicles.
