Title: Detachable connection for motor vehicle exhaust pipe - has flared flange on pipe ends pulled together by split clamping ring
Inventor: KRUEGER HERMANN DR ING
IPC: F16L23/032
Filed: 1976-04-03
Abstract: The detachable pipe connection is used for motor vehicle exhaust pipes. The butting ends of two pipe lengths have flared end flanges and the pipe ends are clamped together with split connectors with internal double conical clamping faces. The clamping device is suitable for thin walled tubes and readily fitted and can be dismantled even if the pipe sections are corroded. The flared flanges (3) at the pipe ends are made by corresponding deformation of the pipe walls. The flared end faces formed are flat and contact directly. The flared conical rim (31) joins directly the flat end part of the pipe. The conical surface formed on the flange has an angle which matched directly that of the split clamping ring.

Title: Installation bringing tennis court out-of-play - includes moisture measuring unit acting through tensioning device to lower net when set degree of moisture is exceeded
Inventor: BOHNE HELMUT
IPC: A63B61/02
Filed: 1977-02-25
Abstract: Installation brings a tennis court out-of-play e.g. for winter closed period or maintenance work. The tennis court has a sand type covering.

Patent DE-2719151-A1 (DE)
Title: Hydraulic system for operating legs of standing offshore platforms - has valve to redirect flow which accelerates lowering and is actuated by impact shock
Inventor: SCHIEMICHEN PETER DIPL ING
IPC: E02B17/02
Filed: 1977-04-29
Abstract: The hydraulic system for operating legs of standing offshore platforms has the majority of the jacks serving any one leg connected in parallel, supplied via a pressure actuated diverting valve. Diverted flow goes to a much smaller number of jacks serving the same leg. The system is fed by a constant output pump. The first impact of the leg on the seafloor during lowering produces a pressure wave in the hydraulic system which trips the diverting valve. Restriction of feed to the smaller number of jacks then accelerates the lowering process; respective capacities of system parts are arranged to ensure the leg not leaving the seafloor. Diverted flow back pressure build up re-establishes supply to the other jacks.

Filed: 1977-06-30
Abstract: Catalyst for the synthesis of MeOH, contg. oxides of Cu, Zn and Gp. II-III metals which are difficult to reduce, also contains gp. VIA metal oxides(S). The catalyst pref. contains 0.01-4.0 wt % W oxide and/or max. 4 wt % Zn chromate, or 0.01-40 wt % Cr oxide. It is prepd. by pptn. of the metals from a salt soln. with Na carbonate, washing, filtering and calcining, then impregnating with the gp. VIA metal cpd. E.g. a soln. of Al, Cu and Zn nitrates was pptd. with NaHCO3. The calcined prod. was impregnated with 0.03-0.06% WO3. The catalyst is suitable for the conversion of CO2 and for the hydrogenation of organic cpds. The rate of MeOH formation is increased and the gp. VIA oxide imparts improved stability and thermostability to the catalyst for longterm use.

Title: Treadle drive for bicycles - with treadle suspended from upright frame member by tensioning arms pivoted to upright at different points
Inventor: STASSEN PETER
IPC: B62M1/24
Filed: 1977-08-16
Abstract: The cycle frame (1) has an upright member (5) to carry the seat. The upright frame member (5) is crossed by a treadle lever (6) suspended by two tensioning arms (7, 8). The tensioning arms are pivoted to the upright bearer at a distance from each other which enables the treadle to assume a parallel position to the ground (4). Pressure applied between the leading treadle link (9) and the two main bearer links (11, 12) causes the cycle to move forwards. Pressure to the rear of these links has the reverse effect.

Title: Nuclear reactor control drive - with ratchet mechanism outside magnets near top limit of rod movement
Inventor: KAPRALOV EVGENIJ IVANOVITSCH
IPC: G21C7/12
Filed: 1977-09-13
Abstract: In a nuclear reactor, the drive for the core control rods consists of a set of electromagnets, each linked to ratchet mechanisms which cooperate with a toothed rack for the absorber rods. The ratchet mechanisms are arranged outside the electromagnets and near the top limit position of the control rods. This makes the dimensions of the electromagnets independent of the size of the ratchet mechanisms. The overall length of a nuclear reactor is thereby reduced.

Title: Hot and cold water mixer unaffected by scale - operated manually or thermostatically and serviceable without dismantling
Inventor: LECHERMEIER FRANZ
IPC: G05D23/13
Filed: 1977-10-20
Abstract: A mixer for regulating the temp. of the water flowing through it, consist of a housing with inlets for cold and hot water, an outlet for the mixt., and a single means of regulating the proportions flowing through the two inlets. The regulating mechanism is unaffected by a build-up of scale and all the parts of the mechanism are readily accessible without dismantling the valve.

Title: Throwaway sheet steel surgical instrument - has scissor blades pressed into U=shape and rolled to form handle grips
Inventor: FLINKFELDT JAN
IPC: B21D53/64
Filed: 1978-05-24
Abstract: The surgical instruments are used only once and then thrown away. A strip of steel is cambered over half its length to form the blade (4) of one leg (1) of a pair of scissors. The remainder (6) of the strip is pressed to a U-shaped section of gradually decreasing width. The U-shaped sections are then bent to form finger grips (8).

Title: Spring actuator for vehicle brake - has piston moved against spring compressed between piston and motor closure cover to release brake on fluid pressure failure
Inventor: BATH MALCOLM
IPC: B60T17/08
Filed: 1979-02-12
Abstract: The brake operating mechanism for vehicles has a spring brake motor and involves a stop (17) for the edge of the piston (12), to resist the restraining pressure. A tension mechanism (60) moves the piston (12) against the pre-tensioned spring which is pressed together between the piston (12) and the motor closure cover (18) to release the brake if hydraulic pressure fails. A tension stop (66) is so arranged that it prevents movement of the piston through the tension mechanism in the contact position with its edge stop.
