Title: Manipulator for industrial handling purposes - is readily adapted by units which can be dismantled or recombined
Inventor: OBONI GUISEPPE
IPC: B25J9/08
Filed: 1975-08-25
Abstract: The manipulator for industrial handling purposes can be readily adapted to given purposes. The manipulator has relatively simple design and it can be readily adapted to given purposes so that the manipulator and its associated actuator are still readily serviced and maintained. The working section has an arm (B) and a number of adjusting units for moving the working section about an axis of linearly. These adjusting units have connecting arrangements which can be interchanged. Hence the manipulator can be built up for a given purpose and those adjusting units which are not needed can be dismantled and the working section can be combined with one or more adjusting units on a fixed foundation.

Patent DE-2539859-A1 (DE)
Title: Screw rotor production method - has intermediary shape with external teeth cut from primary blank for subsequent deeper cutting and finishing
Inventor: RUSSEK ALFRED
IPC: B23F15/08
Filed: 1975-09-08
Abstract: The production process for screw rotors has a first stage involving cutting a primary shape to form an intermediary shape (9) with external teeth (10). The teeth formed are slightly smaller in height than those on the primary shape, but correspond in number and direction of rise to those of the finally finished shape. The central angle subtended by adjacent teeth on the intermediary shape is approximately uniform, and corresponds to that of the finished shape. The teeth (10) and gaps are then sufficiently contoured for the combing by the finishing tool for final machining. In the final machining stage, the teeth of the intermediary shape are completed to the required shape and dimensions using profile rollers.
Patent DE-2545996-A1 (DE)
Title: Aqualung air cylinder manifold - has valve to warn diver when reserve falls and unrestricted supply to second rescue mouthpiece
Inventor: GAROFOLO GIANNI DR ING
IPC: B63C11/22
Filed: 1975-10-14
Abstract: The aqualung gas manifold has two air cylinders coupled to the mouthpiece takeoff via a first control valve. A pressure control valve disconnects the reserve cylinder from the mouthpiece when the pressure drops to a set limit. The diver can then overide the pressure valve by turning a reserve valve while moving to the surface. A second mouthpiece connection is fitted, complete with separate control valve. This allows the system to be used to rescue divers. The second mouthpiece is coupled directly to the reserve cylinder, without passing through the pressure control valve. This allows the system to be attached to a diver in difficulties without danger of the reserve stop cutting off the air supply.

The solid residue is sepd. from the resultant pulp and the prod. is pptd. from the soln. The end prod. is of better quality, the H2SO4 losses are lower and the appts. and technology are simpler than in a 2-stage sulphatisation process (cf. SU 352 850). The insol. residue is sepd. by adding 10-40 g/m3 flocculant, pref. polyacrylamide. The end prod. is sepd. by cooling the soln., pref. after concn. or drying with a hot gas.

With this arrangement, the projecting portions are substantially all in the same direction and at the same angle to the circumference or direction of travel. By choosing an appropriate angle for the zigzag, better grip properties can be obtd.
Patent DE-2606116-A1 (DE)
Inventor: LEHNER ALFRED ING
IPC: B27B31/06
Filed: 1976-02-16
Abstract: So that even timber of second or poorer quality can be worked for producing sawn-timber elements for pallets, cases, parquet boards, furniture parts or the like, the stems are cut up into stem units (E) of predetermined length. The diameter (D1, D2, D3) is measured at a predetermined point of each stem unit, and the stem units (E) are graded according to diameter ranges. Several stem units (E) with the same diameter size or the same diameter range are then fed continuously to a cutting and/or sawing apparatus. When the stems are cut up into relatively short stem units (E), the difference between head and top diameter is relatively small so that so-called industrial timber can also be worked. <IMAGE>

Title: Heat-exchanger, esp. for cryogenic or uranium processes - has integrated tube coil assemblies with tube plates separate from casing
Inventor: SEIFERS HILMAR ING GRAD
IPC: F28D7/02
Filed: 1976-04-21
Abstract: Tubes from the coils pass out through the outer casing via tube plates. The tube plates are connected to the outer casing by intermediate pipe lengths. The heat exchange tubes leads out from the coils of tube as far as the outer casing and terminate there in the tube plates. Pref. the core tube, tube coil and outer casing form one single compact unit which cannot be dismantled. Device is esp. used in very low temp. process work or in uranium enrichment plants operating by the separation nozzle process. Arrangement enables extremely high safety requirements to be complied with with a relatively inexpensive tube heat exchanger. The use of the intermediate pipe lengths enables the outer casing to be of different material from the heat exchanger tubes, to suit the different thermal duty. Repair and maintenance can be carried out on the heat exchanger without dismantling it from the plant.

Title: Thermal storage and distribution with steam or hot water - using additives e.g. lithium chloride to reduce pressure and raise heat capacity
Inventor: ALEFELD GEORG PROF DR
IPC: C09K5/04
Filed: 1976-07-12
Abstract: The heat capacity of a thermal system is increased by using aq. solutions instead of pure water e.g. contg. LiCl allowing a higher temperature to be used at a given pressure level. Used in thermal storage and distribution systems using steam or hot water, e.g. for district heating; for heat storage on the principle of latent heat of crystallisation; for heat pump installations and with solar energy systems for heat collection. Reduction in operating pressure allows reduction in system capital cost; alternatively an increase in operating temperature at the same pressure raises the thermal storage capacity.
