Patent DE-2820376-A1 (DE)
Title: Elongated electric transmission or distribution pole - has longitudinal arranged reinforcing steel cables embedded in concrete in elongated housing
Inventor: POHLMAN JOE C
IPC: B28B23/08
Filed: 1978-05-10
Abstract: The composite pole, has a thin-walled metal casing, a core of non-metallic settable rigid material such as concrete, and reinforcing cables embedded in the core. The reinforcing cables extend between the ends of the casing and communicate with the case. They are pre-stressed prior to the pouring of the concrete into the casing whereby the applied pre-stress is transmitted to the casing. The reinforcing cables are secured to the casing such that the applied pre-stress remains permanently on the casing only. The method of forming the structural part includes securing one of the ends of the reinforcing members to one end of this casing and applying a predetermined stress to the reinforcing cables, securing the other ends of the reinforcing cables to the other end of the casing, pouring concret into the casing, and allowing the concrete to set whereby the stress transmitted to the casing remains permanently on the casing only and is not transmitted to the core.

Title: Plastic pipe flaring tool - in which mandrel filled pipe end is clamped against rotation between notched members whilst flaring tool is applied
Inventor: BUNCH ROBERT EMERSON
IPC: B29C57/00

Title: Drug card filing system - with punched holes in margin of push-through drug cards for easy access and storage
Inventor: LIEDTKE RAINER DR MED
IPC: B42F5/00
Filed: 1978-09-20
Abstract: Tablets of drugs on cards using the push-through system have a wider margin with punched holes along one side of the card so that they can be fastened in the staple or ring type of folder. The perforations can also be arranged on wider margins on more than one side. This allows several cards to be filed in a folder, one above another or one after another in an easily accessible arrangement. This minimises the risk of errors in the intake of drugs when patients are on a complex drug diet. It facilitates the correct regular use of drugs and indicates by the empty shells the rate of consumption. The package is handy for travel and for businessmen. Any necessary instructions can be filed together with the drug cards.

The CaCO3 is dewatered in a rotating vacuum filter and the KCl soln. evapd. or crystallised. Opt. after filtration but before conc., other nutrients are added to give a complete fertiliser. KCl is produced from CaCl for which there is little demand. The CaCO3 by-prod. can be recycled to the desulphurisation or sold.
Patent DE-2856831-A1 (DE)
Title: Liquid level stabiliser - with siphon tube and spring suspended expansion vessel
Inventor: SAUTER HATTO
IPC: G01N25/62
Filed: 1978-12-30
Abstract: A device keeps the level of the liq. in a vessel constant, independent of any extn. or addn. of liq. Such a vessel is required, e.g., to wet continuously a miniature psychrometer. This object is achieved by connecting the vessel by a glass tube like an inverted U with a larger expansion vessel. This tube is fixed to a stand and carries at its end a buoyancy element of nearly the same dia. as the bore of the expansion vessel. The latter is suspended from the stand on a spring with an elastic constant which equals the differential weight of the differential fluid column in the expansion vessel. This compensates the errors introduced by a varying degree of filling of the expansion vessel and has few moving parts.

Title: Sequential crankshaft forging process - uses ring of square cross-section hammer forged to produce good grain flow
Inventor: KOTTLER ADOLF DIPL ING
IPC: B21K1/08
Filed: 1979-08-09
Abstract: A crankshaft is forged from a circular blank in the following sequence of operations. A hole is first punched in the blank to form a ring. The ring is then hammer forged to achieve a square cross-section equal to the cross-sectional area of the crankpin of the finished crankshaft. The ring is then deformed to an oval shape and then to a rectangular block with a rectangular slot. The wall at one end of the slot is removed whilst the opposite wall is forged to a circular section to form the crankpin. Finally transverse holes are formed to receive the main bearing shafts. This system produces a good grain flow in the metal.
