Title: Epoxide resin contg. phosphorus - used for cathodic coating of metals from ungelled aq. dispersion, avoiding staining and discoloration
Inventor: BOSSO JOSEPH FRANK
IPC: C08G59/40
Filed: 1972-12-16
Abstract: Ungelled aq. dispersion of an epoxide resin, contains 1,2-epoxide gp(s). and min. 0.1 wt.% chemically-bound P, (partly) in the form of a quat. onium base, and opt. chemically-bound B and/or min. 1 wt. % oxyalkylene gps., which opt. contains customary additives. Resin is used for coating an electrically conductive substrate acting as cathode. Used esp. for coating metals, e.g. steel, Al, Cu, Mg, etc. High quality coatings are obtd., with good resistance to corrosion, e.g. to salt spray, alkali etc., even on unprimed metals and in the absence of corrosion-inhibiting pigments. The coatings are also resistant to the staining and discoloration often encountered with anodic resins. The dispersions have high throwing power in electrical coating. In an example, 100 (wt.)pts. epoxide resin were reacted with 30 pts. PBu3 in the presence of 16 pts. 85% lactic acid and 16 pts. BuOCH2CH2OH, giving a clear resin soln. with an epoxide no. of 370 and an OH no. of 118 (based on 100% solids). A mixt. of 52 pts. resin, 30 pts. BuOCH2-CH2OH and 350 pts. water was used for coating a steel plate for 45 s at 50 V. The film was slightly sensitive to water initially but, after hardening for 30 min, at 177 degrees C, was smooth and glossy and had a hardness of 3H and thermoplastic properties.

No flue is needed and there is no atmospheric pollution. It provides heating independently of oil or other fuels and is economical to operate.
Patent DE-2366067-A1 (DE)
Title: Internal combustion engine fuel processing - by passing compressed fuel and carrier gas through catalyst into inlet manifold
Inventor: AUGUST PAUL DIPL ING DR
IPC: F02M27/02
Filed: 1973-06-12
Abstract: Liquid fuel is processed by atomising it to a mixt. with a carrier gas (exhaust gases with air added). The mixts. is compressed by a piston compressor and passed near the end of the stroke through a catalyst into the intake manifold of the engine. This injection is timed to take place during the last 20-40% of the opening time of the inlet valve which has drawn in a surplus of combustion air. An auxiliary piston runs at half the speed of the main piston in the cylinder. On its down stroke, it draws in a mixture of atomised fuel and of a carrier gas through a hole in its cylinder wall. At the top of the stroke, a hole in the piston coincides with one in the wall and the mixture, compressed to a high pressure, is injected through the catalyst into the inlet manifold. The suction valve is open through 240 degrees but for the first 60% of its openings time it draws in air; fuel injection is timed for the least 20-40% to ensure ready ignitition of the mixture by the spark plug. The piston head design ensures good ignition in spite of the high excess air ratio. The exhaust gases from the engine contain an extremely low percentage or toxic constituents because of the complete combustion.

Title: Manufacturing a crimping plate type hose clamp - with two half scales hinged at one end, and mounted on a plate pressed onto the hose pipe
Inventor: WEINHOLD KARL
IPC: F16L33/12
Filed: 1974-01-18
Abstract: The assembly consists of a pipe end over which a hose can be pushed. the pipe end is provided with a square sectioned groove. A crimping plate is provided which can be attached to the pipe-end. This plate holds a pin on which two clamp halves can hinge. The clamp halves are secured together when closed, and the crimping plate has a hole which is large enough to slide over the pipe end to bring it in line with the groove. The hole in the plate extends to one side into a slot in which the head of the hinge pin is mounted. The pin serves as hinge for the scales. A special tool is used to press the crimping plate into the groove in the pipe end, thereby securing it in position. The end of the pipe has a shoulder so that the pipe can be attached to a hose coupling by means of a sleeve nut.

Title: High jump and pole vault training aid - uses plastics strip as height market instead of rod or lath which is fastened to uprights by piece of bent wire
Inventor: ZACHARIAS THOMAS
IPC: A63B5/04
Filed: 1974-10-30
Abstract: In high jump or pole vaulting competitions a light rod or lathe is mounted between the uprights and if it is dislodged by the competitor it gives a clear indication of failure. However, during training for these events much time is wasted in replacing the rod. To overcome this difficulty it is proposed to replace the rod by a strip (A) of tear resistant plastics. The plastics strip (A) is supported by a piece of wire (C) bent to a U-shape with a loop at the end of each leg. Elastic bands (B) which pass through these loops are attached to a clip (D) which in turn is fixed to the upright (E).
