Patent DE-4028590-A1 (DE)
Inventor: ELSNER THOMAS
IPC: E04H/
Filed: 1990-09-08
Abstract: The invention concerns a vehicle-parking system with a number of vehicle pallets (4) which can be moved on a planar network of mutually perpendicular tracks (8, 9). Each pallet has its own drive unit (17) which is supplied with electric power through power pick-ups (25, 26) which make contact with current-carrying rails (23, 24) running along the tracks (8, 9). So that information concerning the lateral and longitudinal displacement of the pallets (4), and the corresponding drive programme, can be transmitted without the need for special signal lines to the pallets (4), the invention proposes that each pallet (4) is fitted with at least two separate pairs of power pick-ups (25, 26). A fixed selection unit displaces the current-carrying rails (23, 24) and the power pick-ups (25, 26) relative to each other in such a way that each of the two pairs of pick-ups (25, 26) only makes contact with either the rails (23) running in one direction or those (24) running in the direction at right angles. The two p airs of pick-ups (25, 26) are connected to a discriminator circuit (22) which activates various drive programmes, depending which pair of pick-ups (25, 26) is picking up power.

IPC: B29C59/04
Filed: 1990-11-12
Abstract: A temperature-controllable roll 1 serves as a sealing tool, on the circumferential surface of which a number of plastic film tapes 14, 15, 16 are sealed to one another under pressure and application of heat. The plastic film tapes run at equal or different distances from one another onto the circumferential surface of the roll 1 and are led over pressure rolls 2, 3, ...7. These pressure rolls rest under pressure on the circumferential surface of the roll 1. The plastic film tapes run through the contact surfaces between the pressure rolls and the roll 1. The plastic film tapes are equipped on one or both sides with sealing layers, which are fused by the effect of heat, so that a sealing of the plastic film tapes arranged in layers one on top of the other occurs on the circumferential surface of the roll 1. <IMAGE>

Patent DE-4140228-A1 (DE)
IPC: B03C3/68
Filed: 1991-12-06
Abstract: The invention concerns a method of removing dust from flue gases by means of an electrostatic filter (E). The filter (E) is located in the flue-gas flow (R), and a d.c. voltage is applied across the filter to ionize the dust particles flowing through it. In order to optimize the operation of the filter, from both the environmental and the economical point of view, the invention calls for the dust concentration to be continuously measured at the filter outlet, upstream of the desulphurization unit. An upper limit and a lower limit are set for the dust concentration, and process parameters previously determined experimentally by a comparator (V) from a memory (S) to optimize the process as regards the degree of dust removal and efficiency are derived as signals to control the filter.

Title: Alignment control for coal face cutter with servo advancement - has displacement monitors on advancing rams and processor control to correct for non linearity after set number of cuts
Inventor: GEUNS GUY DIPL ING
IPC: E21D23/14
Filed: 1991-12-20
Abstract: The cutting head (2) is pulled along the coalface by a servo drive along a guide positioned by a line of positioning rams (4). The rams drive the cutter into face for a preset cutting depth. The servo rams drive the cutting forward and the displacement is monitored by sensors on each ram. The processor sums the displacements for each ram and using two reference rams spaced apart, computes the optimum line between the reference points. This is compared with the actual line and correction is applied during the next cut. The correction can be applied at set intervals, e.g. at the end of a shift. The adjustments can be manually corrected. The deviation in linear cutting results from play in the coupling between the rams and the line. ADVANTAGE - Simple correction for cutting linear face, simple to adjust.
