Title: DC driver speed regulator for guillotines has load-variation detector - determining instant load changes for adding into comparison loop
Inventor: THIEMANN HANS
IPC: H02P7/298
Filed: 1973-07-25
Abstract: The speed regulating circuit, for d.c. drives driving guillotines and other devices with greatly-varying loads, detects the instantaneous load changes on the motor and matches the motor power to load conditions immediately before determining speed changes. The load-variation detector is located between the machine and its drive motor and produces a control signal for passing to a second comparator. The actual speed of the motor is determined by a tachogenerator and is compared with a reference. The resulting difference is fed over a PI-generator to the second comparator which also receives a signal representing the motor actual current and the output of the loading-variation detector. The second comparator output is amplified and fed to a pulse generator which controls the thyristor in the motor current supply circuit.

Title: Unmatured soft cheese prodn. - by scouring part of milk with pure bacterial culture and coagulating remainder with rennet
Inventor: GAGESCH BRUNO MICHAEL
IPC: A23C19/05
Filed: 1974-06-11
Abstract: Prodn. of unmatured soft cheese is improved in that in the first stage a part of milk is sourced with a pure bacteria culture, in the second stage, after curdling, another part of the milk is coagulated by the addition of the milk soured in the first stage, and in the third stage, fresh milk is added and the remainder of casein is coagulated by addition of rennet, the resulting curd is processed in the normal way. The process can be carried out continuously. The ratio of the acid-curdled casein to the rennet-coagulated casein is 30:70 to 40:60. The consistence of the product is regulated by properly adjusting the acid-casein, rennet-casein ratio. The above specified ratio gives products best suited for the German market. The process is accelerated and the capital and operating expenditure is reduced.

Title: Slide bearing surface lubrication - using centrifugal pressure differential arising from rotation of bearing part e.g. spindle
IPC: F16C33/10
Filed: 1974-07-23
Abstract: The rotation of one bearing part e.g. the spindle (1), creates centrifugal forces, which forces lubricant from a chamber (6) out through channels (7). The lubricant is pressed into distribution chambers (8), distributed onto the slide surfaces and into lubricant connection chambers (5). The chambers are not influenced by the centrifugal force, and gives rise to a pressure differential between the inflow path (6-8) and outlet path (5, 4) of the lubricant, causing the latter ot circulate. The pressure differential increases with the increase in RPM of the rotor (9), pressing the lubricant into the outlet path, and forming a pressure-proof film on the bearing surfaces.

Title: Digital electrical system for signalling and location of leaks - consists of measuring cable with strips of conductive material which can absorb the leaked fluid
Inventor: ISSEL WOLFGANG DIPL PHYS DR IN
IPC: G01M3/18
Filed: 1974-11-09
Abstract: The strips located along the length of the leak-signalling cable are of a given length (about 5m) and the material used is rendered conductive by filling with electrically conductive powders. Between each pair of strips is an electric switch device permitting the conductivity of each individual strip to be measured in turn. By feeding x-impulses into the cable from a control centre, the electrical conductivity of the x-th strip can be measured, indicating whether it has absorbed leaked fluid. The strips may also be made of synthetic material with electrically conductive properties, obviating the need for filling with conductive powders.
