Title: Filter element and process for the production of filter elements
Inventor: SCHUMANN KLAUS
IPC: F01N3/022
Filed: 1988-01-26
Abstract: A filter element (1) (Fig. 1) is composed of a multiplicity of adjacent filter cells made of textile material, the individual filter cells (4) being constructed to be closed on one side and the open side of the filter cells (4) forming the intake side (6), and efflux cells (5) having efflux-side outlet orifices being provided between the filter cells (4). The filter cells and the efflux cells are each provided with spacer projections (8) distributed over their surfaces on the side walls (10) facing each other. These spacer projections (8) are preferably formed by a zigzag-shaped profiling of the side walls (10), the projections (8) of opposite side walls (10) of a filter cell or an efflux cell pointing directly to each other. The projections (8), at high pressure differences between intake and efflux side, can abut each other and thus reinforce the side walls (10) against one another. A collapse of the filter or of the side walls (10) of the efflux cells is thus avoided. <IMAGE>

Title: Sensor-controlled tracking device, especially for the levelling of ground surfaces
Inventor: PERTL PETER
IPC: E02F3/84
Filed: 1988-08-14
Abstract: With a sensor-controlled tracking device known per se, the altitude of a working device can be automatically maintained. Specific tilt positions of the working device, however, can either not be preset or can be preset only at great cost. In order also to provide an automatic tracking device for the maintenance of a specific levelling position of a working device, a further laser sensor (11') is provided as well as a laser sensor (11) known per se. Both laser sensors (11, 11') are supported on the working device (3) and control, separately or together, at least two actuators (7) so that, in the event of a deviation from a reference plane (R) predetermined via a laser generator, both laser sensors (11, 11') are tracked automatically onto this reference plane (R), by which means the working device (3) is maintained in a predetermined position. The sensor-controlled tracking device is particularly suitable for ground working devices. <IMAGE>

Title: Lead-acid battery
Inventor: HULLMEINE UDO
IPC: H01M10/08
Filed: 1989-01-30
Abstract: The sensitivity, peculiar to the positive PbO2 electrode of lead-acid batteries, with respect to changes of the charging/ discharging conditions, to which the positive electrode responds with pronounced fluctuations in capacity, can be overcome by using an electrolyte in which tin is dissolved as tin sulphate. The SnSO4 addition in terms of its mount, is particularly beneficial if the molar ratio SnSO4 : H2SO4 in the freshly manufactured, charged battery (accumulator) is from 1 . 10<-4> : 1 to 2 . 10<-3> : 1, while the molar ratio PbO2 : H2SO4 is within the limits of from 0.08 : 1 to 1 : 1. The molar ratio PbO2 : SnSO4 is preferably from 700 : 1 to 50 : 1, the H2SO4 molarity in the electrolyte being from 3 to 5. The SnSO4 addition effects stabilisation of the PbO2 electrode at a high capacity level. The addition is added to the cell electrolyte in predissolved form.

Title: Pause control in telephone stations with a telephone number memory
Inventor: HARTMANN KARL-DIETER
IPC: H04M1/27485
Filed: 1989-03-16
Abstract: The invention relates to a method for pause control in telephone stations with a telephone number memory, an exchange code memory and a flash key, a longer pause being required after the exchange code has been dialled in order to set up exchange dialling. The object is to use the flash key criterion as an exchange code, this criterion also being intended to be used to initiate subscriber services which can be implemented only after a substantially shorter pause following the flash key criterion. To achieve this, the flash key criterion is stored as an exchange code in the exchange code memory as a comparative criterion, a longer pause is inserted when a telephone number with a preceding flash key criterion is compared and no pause is inserted if the flash key criterion is absent, and, for dialling without a flash key criterion at the beginning of the subscriber number and, after dialling this subscriber number with an appended flash key criterion from a further memory, a short pause is inserted to initiate the subscriber service.   The method can be used in modern telephone systems with subscriber services.
Patent DE-3908777-A1 (DE)
Title: Pump
Inventor: WESTERFELD MANFRED
IPC: F04B53/00
Filed: 1989-03-17
Abstract: A pump for generating pressure in hydraulic circuits, having at least one hydraulic regulating unit (final controlling element) and a holding tank for hydraulic fluid, such as is available, in particular, in the form of the axial-piston pump as a high-performance pump having good capacities and high robustness, often produces unacceptable noise, which, in the customary arrangement, is emitted particularly strongly in a holding tank for hydraulic fluid and is superimposed with characteristic vibrations of the tank walls. The invention overcomes the problem by accommodating the pump in a vibrationally damped manner in a pump casing separate from the holding tank. The pump casing is expediently formed as a closed capsule made of heavy material, the pump casing preferably being mounted in a vibrationally damped manner and the way in which pumps are run through the pump casing likewise taking vibration damping into account.

Patent DE-3926362-A1 (DE)
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/32
Filed: 1989-08-09
Abstract: A stack injection molding system for conveying melt from an upstream heated nozzle (12) seated in a fixed mold platen (16) to an aligned downstream heated nozzle (18) in a movable mold platen (22). The upstream and downstream nozzles (12, 18) each have a nose portion (62,112) with a forward face (64,114) which abuts against each other in the parting line (74) in the closed position. The melt passage extends through aligned central melt bores (48,118) in the nozzles which taper inwardly adjacent the forward faces (64,114) to form a sprue gate where they join. While both nozzles (12,18) have an integral electrical heating element, only the heating element (78) of the upstream nozzle (12) has a circular forward portion (102) which is brazed in the nose portion (62) to encircle the melt bore (48) and provide more heat and better control adjacent the sprue gate. Before the mold is opened along the parting line for ejection during the injection cycle, power to the heating elements (78,124) of the nozzles (12,18) is turned off to avoid drooling of melt from the open sprue gate.
