Title: Turbogenerator winding former centering arrangement - has several radial tensioning bolts positioning windings to compensate rotor imbalance
Inventor: D HAM REINHOLD DIPL ING
IPC: H02K3/46
Filed: 1976-08-11
Abstract: The arrangement is for centering a cylindrical winding former in an external cylindrical hollow rotor body, in particular for a turbogenerator having superconducting exciting winding. The rotor is designed such that subsequent centering of the inner-lying winding former relative to the outer rotor-body can take place, in order to balance out any imbalance due to inaccurate centering. The winding former carries on both its end-faces coaxial extension pieces, and several radial tensioning bolts arranged symmetrically within the outer rotor-body to act radially on the extension pieces, these bolts being made adjustable from outside the rotor-body.

Title: Unreinforced full disc brake - has rotary thrust ring acting against support ring via parallel roller end faces
Inventor: KLAUE HERMANN DR ING
IPC: F16D55/18
Filed: 1976-09-06
Abstract: The unreinforced full disc brake is partic. for motor vehicles. The two thrust rings are centred in relation to each other by their ram faces and the actuating rollers between them. The ring which is rotated is coupled to the support ring acting against the second brake disc by cylindrical rollers, whose thrust faces are formed by parallel end faces. The design prevents seizure of the expander unit under high thermal loading, where heat is transmitted from the rear of the linings and causes unequal expansion of the three rings.

Title: Controlled evapn. of sensitive materials - having flat surface with baffles heating coils and weir for constant level
Inventor: RUNTE HELMUT DIPL ING
IPC: B01D1/22
Filed: 1976-10-29
Abstract: Gentle evapn. of liq. and liq. mixts. involves allowing the liq. to flow across the horizontal flat surface of a shell. Evapn. occurs by indirect heat transfer between a heating medium in the shell and the liq. The level of liq. above the heating surface is controlled at 1-5 mm by means of a weir. In a vessel, >=1 such horizontal shell is located. This should have an inlet line and at the opposite end a weir with an outlet behind it. Heating can be provided by elements attached to the shell wall and the surface is divided into channels by vertical baffles. Used esp. for evapn. of sensitive liqs. existing systems e.g. falling films, suffer from the problem of encrustation and possible overheating of the material with consequent damage. The system described allows better control.

Title: Leaching test for mineral samples - includes forcing solution of leaching agent under pressure through core sample using compressed air from cylinder
Inventor: FROEHLICH CHRISTOPH
IPC: G01N15/08
Filed: 1976-11-05
Abstract: The test appts. for mineral samples taken from bore holes consists of a cylindrical pressure chamber (1) in which is placed the core plug under investigation (2). One end of a vessel containing leaching agent (3) is connected via a stop-cock to the lower end of the chamber, the other is connected to a compressed air cylinder (6).

Title: Cable loop prodn. - from divided strand sections with their ends laid in the core so that all the strands form the loop
Inventor: KASCHEL JOSEF
IPC: D07B1/18
Filed: 1977-03-18
Abstract: In the prodn. of a loop from a multi-strand cable, the cable end is divided into two to be wound together against each other to form a loop, each section running in the opposite direction at the loop. After the loop has been formed from a number of strands, each cable section is formed into a cable-type section, to be laid into the undivided cable section at the core. The remaining strands of each section are laid in the gaps formed by the twisted section. The end sections of the remaining strands are thinned and twisted to a further section, only insignificantly thicker than the original core of the cable, and is laid near the original core of the cable. All the strands are used in the change-over from the rope to the loop at its end.

Title: Rolling mill delivering constant thickness strip - has operating conditions optimised using computer controlled variable factors
Inventor: AHRENS DIETER DIPL ING
IPC: B21B37/48
Filed: 1978-03-10
Abstract: The thickness of steel strip after passing between the rollers (I) of a rolling mill is controlled by a computer. The values of the factors on which the thickness depends are the initial thickness of the strip, the difference between the actual roller position and the required roller position, and the input velocity. Also taken into account is the spring constant of the roll stand and the increase in the slope of the plastic deformative curve. These values are fed into the computer together with the measured thickness of the strip as it leaves the rollers. The computer then determines the required values of the various factors in order to maintain the required final thickness.

Title: Controlled combustion hydrocarbon gas burner - has temp. sensor for establishing calorific value of gas-air mixture to provide continuous supervision
Inventor: AUGUSTO ANGELI
IPC: F23N1/02

Abstract: The burner (7) uses a mixture of hydrocarbon gas and air and is monitored to maintain the correct mixture ratio. The monitor includes an oven (5) in to which a continuous sample of the mixt. is fed. As the mixture is burning, its calorific value is established by measuring the combustion temp. by a thermo-element. If the recorded temp. deviates from the required value, a control signal is produced which regulates the supply valve (6) for the hydrocarbon gas until the combustion mixture has the correct ratio.
