Title: Strain gauge ring for stress measurements during drilling - is fitted with centering bush which facilitates alignment of ring on work piece
Inventor: ORT WERNER DIPL PHYS DR
IPC: G01L1/22
Filed: 1975-12-24
Abstract: The strain gauge ring for internal stress measurements during machining operations consists of three strain gauge elements arranged at 45 deg. intervals on a supporting film. The film is attached to a circuit board by an adhesive disc and connections are made between the circuit board and strain gauge elements. A steel centering bush is soldered into the centre of the conductor plate. In order to align the gauge assembly (1) with the selected position on the work piece (7) a centering pin (13) is passed through the central boring (9) of a permanent magnet clamping assembly (11) and through the bush in the centre of the strain gauge ring. The pin is removed after the ring has been fixed to the work piece and is replaced by the drill of the boring machine.
Patent DE-2604769-A1 (DE)
Inventor: HENNIG HEINZ
IPC: B61F5/20
Filed: 1976-02-07
Abstract: The load of the wagon is transmitted via a sliding plate support (1) consisting of a connecting-member guide (3) and sliding element (4) on laterally arranged pneumatic spring carriers (11) and is transmitted from here via pneumatic spring means to the frame (7) of the bogie (17). Each pneumatic spring carrier (11) is connected to the frame (7) in an articulated fashion via at least one longitudinally located connecting rod (6a). In the longitudinal direction, the joints (16) guide the pneumatic spring carrier (11) virtually without play, the perpendicular play of the pneumatic spring means only being slightly influenced. The space in the centre of the bogie which is often required remains, with this device, open as far as possible. Extremely small bending radii can be executed. <IMAGE>

Title: Horizontal deflection control circuit - clamps line pulses during line forward sweep to certain zero potential for energy uptake
Inventor: KRAUS HEINZ ING GRAD
IPC: H04N3/22
Filed: 1976-05-08
Abstract: Control circuit receives a control signal voltage, a function of the line forward sweep period. This control signal voltage is converted into a saw-tooth voltage and applied to a phase comparator which excites a driver stage when the saw-tooth voltage exceeds a specified reference voltage. The driver stage makes a current gate in the current supply circuit conducting with a certain phase shift. Line pulses (forward sweep the fly-back pulses) are applied to a voltage doubling circuit which is the control circuit input and clamps the line pulses during the forward sweep period to a certain zero potential, e. g. amplitude of the back-kick pulse.

Title: Sulphur prodn. from sulphur dioxide-contg. gases - by reduction with gaseous reducing agents
Inventor: FISCHER HERBERT
IPC: B01D53/86
Filed: 1976-06-25
Abstract: Prodn. of sulphur from SO2-contg. gases by reduction with gaseous reducing agents, cooling the reaction gases, catalytic reaction of SO2 and H2S, and sepn. of the resulting sulphur by condensation, is improved by first purifying the SO2-contg. gases, and then reducing SO2 with H2 and/or C-contg. cpd(s) and/or hydrocarbons. If the SO2 content is less than 50 volume%, the reduction is carried out catalytically at 300-500 degrees C (pref. 350-450 degrees C); if the SO2 content exceeds 50 vol.%, the reduction is carried out thermally (without any catalyst) at 800-1250 degrees C (pref. 950-1050 degrees C). The resulting sulphur is sepd. The residual SO2 is reacted with H2S by the Claus process and the additionally produced sulphur is sepd. by condensation, COS and CS2 which may be formed as by-products are hydrolysed or hydrogenated. SO2-rich gases can be economically processed. The volume of the appts. is not too large, the consumption of energy is relatively low and there is no catalyst poisoning. The effluent gases are sufficiently purified.

Title: Monitor to form frequency proportional to power - counts pulses to set flip=flop whose state is entered in register
Inventor: BUEHLMANN GEROLD PAUL
IPC: H02J3/14
Filed: 1976-08-28
Abstract: The max. power monitor has a device producing a rectified voltage proportional to power and a voltage/frequency converter converting this voltage into a frequency proportional to power.

Title: Load protecting fuse for incorrectly poled supply - is located between earth and neutral line coupled to load
Inventor: NEUHAUS DIETER
IPC: H05K1/18
Filed: 1977-01-27
Abstract: The fuse is incorporated into the neutral line between the load (22) and the d.c. supply (17) i.e. the neutral line (14) in the supply is connected via an earthed lead to the neutral line (20) of the load. The latter line is earthed via the fuse (23). The load is connected to one end to the live line, and at the other to the neutral line from the supply. If the two supply leads are connected the wrong way round to the load unit terminals, the fuse blows, but the load remains unaffected.
