Patent DE-2629275-A1 (DE)
Title: Gas permeable body - for treating molten metals contains a metal treating agent and substance which forms passages on heating (SW 9.5.77)
Inventor: EL GAMMAL TAREK PROF DR ING
IPC: C22B9/10
Filed: 1976-06-30
Abstract: Parent patent relates to a heat insulating gas permeable carrier for introducing inoculating agents into molten metal. To prevent sudden disintegration of the carrier in case of blockage, channels or passages are provided in the carrier body by incorporating an (in)organic, and/or synthetic substance which is volatile, and disintegrates with vol. redn. on heating. By providing channels or passages readily for the evolution or movement of the vapour or melt formed by the inoculating substance, the danger of explosion with health hazard is eliminated.
Patent DE-2635653-A1 (DE)
Title: Piston drive in pressure chamber for power station - has high pressure chamber for cylinder between vacuum and ambient pressure
Inventor: HELLINGHAUSEN HANS
IPC: F04B31/00
Filed: 1976-08-07
Abstract: The piston drive is used for several cylinders in a pressure chamber. The drive utilises very high pressure supplied only once. This pressure is maintained and atmospheric pressure is converted for acting on piston. Vacuum is continuously generated in a cylinder. This drive is used in power stations and ships. The plant requires no energy apart from that for starting. A high pressure chamber is held continuously at constant pressure by the use of atmospheric pressure and vacuum cylinder by corresponding pressure ratio. This chamber holds a double vertical cylinder. Each cylinder has piston on a reciprocating rod. Pressure acts on upper piston and is transmitted to lower one whose cylinder is evacuated. The upper piston moves readily upwards.
Patent DE-2646575-A1 (DE)
Title: Digital lock for furniture doors - has rotatable locking plates on axially slidable shaft moved by spring loaded carrier lug
IPC: E05B37/04
Filed: 1976-10-15
Abstract: The digital prevents reading of the combination figures when unlocked. To select the correct combination for the unlocking, the dial is rotated and the carrier lug (28) rotates the locking plate (32). When the plate reaches its unlocking position, the dial is pulled outwards, so that a detent ball settles in a ring groove, which seats the carrier lug in the notch (29) of the middle locking plate. If the carrier lug is not flus with the notch, the carrier lug moves radially inward along the abutting surface, of the corresponding lock plate seat bushing. The carrier lug has a certain dead travel before it comes to rest in the notch. It is then possible to bring the locking plate into the corresp. unlocking position.

Title: First driven gear of a quartz clock with step-motor - is a silicone rubber toothed disc. held between supporting plates
Inventor: HETTICH HUGO
IPC: G04C13/11
Filed: 1976-11-15
Abstract: Conventionally, the step motor moves the mechanism or at one second intervals: play needed between the gear teeth makes the continual stop-and-start somewhat noisy. To quieten the action, rubber(covered)gears are used. A form more economical to mfr. is here provided, in which the gear driven by the step motor pinion is made as a toothed disc of silicone rubber, held between support plates of stiffer material. At least one of the support plates is fixed to the gear axle. The toothed silicone rubber disc is pref. stamped out, and may be made as a ring of inward-facing teeth.
Patent DE-2653756-A1 (DE)
Title: Impact tool adaptor working in both directions - has two coaxial serrated bodies adjustably spring-loaded together
Inventor: TRAUTMANN GUENTER
IPC: B25B21/02
Filed: 1976-11-26
Abstract: The impact tool adapter with adjustable torque is for use with flexible shafts and screwdrivers, socket spanners etc. It works in both directions, comprising two coaxial bodies with mating serrated end faces held together by an adjustable spring (9). As the nut etc. is tightened to a specific torque, the bodies are thrust apart, the serrations riding over each other for one tooth at a time as they do so. This releases the torsion in the flexible shaft, causing each tooth flank on one body to strike against the side of the serration as it drops into the next recess, exerting an impact torque on it in the process.

Title: Passivation of germanium substrate by chemical vapour deposition - using volatile hydrocarbon and silicon cpds., preventing diffusion and etching
Inventor: JACOB HERBERT DIPL CHEM DR
IPC: H01L21/314
Filed: 1977-03-22
Abstract: Passivation of Ge substrates is effected by chemical vapour deposition of the reaction prod. of a mixt. of 0.1-100 vol.pts. volatile 1-8 C hydrocarbon cpd., esp. C2H4 and 1 vol. pt. volatile Si cpd., pref. esp. SiH4, at 600-930 degrees C. Passivation is effective enough to prevent diffusion of dopants from the epitaxial growth layer and etching of the substrate by corrosive reaction gases. In an example As-doped Ge discs were coated for 10 min. in 0.65 1/min C2H4, 0.02 1/min. SiH4 and 33 1/min Ar at 750 degrees C. The passivation layer formed covered with front sides and edge of the back of the discs. It was unaffected at the sides when the back was polished away and unchanged when the back was then coated with GaAs0.62P0.38 using AsH3 and PH3.

Title: Sulphuric acid or oleum prodn. by contact process - with recirculation of gas from first absorber to end of first contact stage, increasing efficiency
Inventor: JENNIGES ERNST
IPC: C01B17/765
Filed: 1977-05-14
Abstract: The process is carried out with gases contg. >10 vol.% SO2 in 2 contact stages, the first being followed by cooling absorption of the SO3 formed and reheating. The novelty is that 10-40 vol.% of the gas from the first absorption stage is mixed with the gas from the penultimate layer of the first contact stage and the combined gases are passed to the last layer of this stage. Pref. the gas from the penultimate layer is cooled to 480-500 degrees C in a heat exchanger and then mixed with 10-15 vol.% of the gas from the first absorption stage. The efficiency of the last layer of the first stage is increased, making operation more economical. The heat exchanger after the second contact layer of the first stage and the circulation blower can be smaller than usual.

Title: Fluid flow enthalpy difference measurement - involves comparison temp. and temp. measurement before and after tapped flow de-mixing
Inventor: ROETZEL WILFRIED PROF DR ING
IPC: G01K17/08
Filed: 1977-06-16
Abstract: A device (1) is used for measuring the enthalpy difference of a fluid flow compared with a constant or variable comparison temp. are designed for uncomplicated comparison measurements, to avoid constructional problems with narrow measurement sections, and to avoid blocking of narrow measurement tappings in the main flow channel. A flow proportional to the square of the main flow is tapped off and then mixed with the main flow after attaining the comparison temp. The difference between the average main flow temp. before and after the remixing is proportional to the enthalpy difference. The square of the flow is achieved using a nozzle, capillary, or valve.
