Patent DE-3941837-A1 (DE)
Inventor: FRIESE KARL-HERMANN DIPL PHYS
IPC: G01N33/00
Filed: 1989-12-19
Abstract: Proposed is an electrical-resistance probe for monitoring gas compositions, in particular exhaust gases from internal-combustion engines. Compared with prior art resistance probes, that described has the advantages of a short response time and significantly greater resistance to ageing. This is due to the fact that the semiconducting electrical-resistance layer is inserted or sintered into recesses or slits provided for this purpose in the prefabricated sensor substrate, and a porous, electrically non-conducting engobe or a protective layer structure in the form of a grid or mesh is then applied. This permits access of the gases being monitored to the semiconductor layer, at the same time protecting the semiconductor layer from corrosive, erosive and/or cavitative attack by the exhaust gases.

Title: Forming electrical signal corresp. to amt. of tobacco strand - combining signals corresp. to dry and moist streams to tobacco in cigarette strand machine
Inventor: SIEMS WOLFGANG DR
IPC: A24C5/18
Filed: 1990-07-21
Abstract: An electrical measuring signal pick-up (28,28a,28b) registers the amt. of flow of the dry mass of tobacco, pref. in one strand (2b,2a,2c). Another electrical measuring signal pick-up (10) registers the ampt. of flow of the moist mass. A calculator (33) produces a signal corresp. to the amt. of flow of the total mass of the tobacco strand by combining both pick-up signals. - The dry mass pick-up uses a light source (29) of such a wavelength that the light component reaching a photo-electric receiver (31) depends upon the dry mass of tobacco. The transmitted light lies between 850 to 910 nanometres, pref. ca. 880 nm. The moist mass pick-up is in the form of a capacitor (5b) producing an electrical h.f. field through the tobacco. The attenuation of an oscillating circuit contg. the capacitor serves as a measure of the moist mass. The calculator's output signal is fed to a comparator (36) for comparison with a stipulated value signal. The output signal corresp. to the difference is supplied to a control (39) for an adjuster (7) affecting the tobacco flow. (5pp Dwg.No.1/1)

Patent DE-4119391-A1 (DE)
Inventor: FUDERER ERICH
IPC: B61H15/00
Filed: 1991-06-12
Abstract: In the shoe-brake unit proposed, a push-rod designed as the threaded spindle of a clearance-adjustment device, is mounted by its ball end (3) in a matching bearing cavity (4) in the brake-shoe holder (6). This makes it possible for the push-rod (2) to move without restraint in any direction relative to the brake-shoe holder (6) while maintaining a continuous and uniform thrust over the brake-holder, hence ensuring that no flexional or shear forces are produced in the push-rod (2) at the point where the push-rod is linked to the brake-shoe holder (6). In order to hold the push-rod (2) so that it cannot rotate about its longitudinal axis, a bolt (12) passes transversely through the ball end (3), the protruding ends of the bolt fitting in horizontal grooves (14) in the brake-shoe holder (6). A coupling thrust-transmission coupling which is tightened by rotation and is releasable only when a given limiting torque is exceeded can be fitted between the ball end (3) and the push-rod (2), thus making it possible to reset the clearance-adjustment device manually by turning the push-rod.

Title: Mineral activation - uses given charge time for dried material within the time span between feeding and extraction from pan grinder
Inventor: OHRDORF KARL-HEINZ
IPC: B02C15/14
Filed: 1991-07-16
Abstract: To activate layered minerals esp. bentonite, the material is predried so it is less damp. After the activating material has been added, a set time is established as the charge time for the discontinuous operation of a mixing and kneading pan grinder. After the charge time, as the mixing and kneading pan grinder continues to operate, the activated material is discharged.

A preparation time is established according to the characteristics of the raw material and the activating material, together with the kinematic values of the mixer and the kneading pan grinder. The material passage is within a discrete time span, and is used as a time window within the total running time of the pan grinder, as a charge time between the feed of the material into and withdrawal from the pan grinder. ADVANTAGE - Reduces weight of materials being carried, and also allows the process to be adjusted according to the nature of the material and the nominal values selected
