Title: Cheese stack turning device - using own weight to tension springs for stack clamping
Inventor: KRAUSE FRIEDRICH
IPC: A01J25/16
Filed: 1973-04-21
Abstract: In a device to turn a stack of moulds filled with cheese through 180 degrees, the car carrying the stack is rolled on rails into a C-shaped tippler. Hydraulic rams lift the car off the rals and cause its wt. to tension a set of springs and to displace hydraulic fluid from one ram to a clamping ram for the stack. After the tippler has been turned on rollers through 180 degrees, the hydraulic fluid is allowed to return the rams to the initial posn. This design requires power source for the stack clamping press. because it makes use of the stack wt. The stack is revolved around a horizontal axis at right angles to the direction of transport. The track need not be interrupted for the turning device and its location can be chosen without any restrictions.

Title: Skin pass rolling steel and non-ferrous metal strip - with rows of hydraulic cylinders under lower back-up rolls
IPC: B21B31/26
Filed: 1973-11-02
Abstract: The rolling mill has >=2 thin, flexible work rolls on which press. is exerted by two sets of back-up rolls, and the novelty is that >=1 set of back up rolls is subjected to a common liq. press. (communicating liq. press. system) so that a continuous, uniform press. is exerted during skin-pass rolling even when changes occur in strip thickness. The upper press. rolls pref. occupy a fixed position, the liq. press. being exerted on the lower back-up rolls; eccentrics above the upper rolls adjust the roll-gap, and the work rolls can be withdrawn from the opposite side to the drive shafts. The work roll surfaces can be sand-blasted and a washing-, oiling-, and/or straightening unit can be used in conjunction with the mill. Used for skin pass rolling of coiled strip immediately prior to deep-drawing so no ageing, and hence no stretcher strains, occur during the shaping operations in the press.

Title: Dust content of flue gas continuously determined - using moving filter band with radiometric dust measuring adjacent filter point
Inventor: DRESIA HEINRICH DIPL PHYS DR
IPC: G01N23/08
Filed: 1973-11-13
Abstract: A measuring device for determining the dust content of gases, esp. exhaust or flue gas, comprises a filter chamber on the upstream side of a suction pump and a filter band passing through the chamber to filter the dust; the rate of deposition is measured by radiometric mass determination. The filtering point and measuring point are combined in the one filter chamber. A continuous drive propels the filter band through the surrounding housing; the suction pump drawing out the filtered gas through the suction pipe operates continuously. Where the filter band has a pitted or uneven surface, it pref. passes through inlet and outlet slits in the housing, thus itself constituting a labyrinth seal at each. One side of these slits is pref. adjustable in height, to regulate the seal. The detector operates continuously. The forces on the filter band due to sealing and suction occur at different places, thus reducing local stresses inthe band. The filtering and measuring position can be closed together, thus reducing time-lag in the readings.
