Patent DE-1807667-A1 (DE)
Title: Nuclear fuel element manufacture - using phenol resins and maleic anhydride
Inventor: BEUTLER HANS
IPC: G21C3/62
Filed: 1968-11-07
Abstract: Coated fuel particles are poured into a mould, which is filled with a mixture of 75% phenol resin + 15% graphite + 10% maleic anhydride (% are by wt.). This is polymerised at 80 deg.C. in 2 hr. and tested for mechanical faults after the removal from the mould and finally carbonised at 1000 deg.C. The nuclear fuel particles consist of a core of UO2 or ThO2 particles (grain size 200-250 mu) with a smooth coating of anisotropic, porous, pyrolytic carbon, 5 mu thick, (prepared by treatment at 1100 deg.C. with 0.10 cm 3/ cm2/ min. of a hydrocarbon gas, e.g. propane), and a rough overcoating of isotropic, pyrolytic C, 13 mu thick, (prepared by treatment with a hydrocarbon gas at 1250-1300 deg.C., at a rate of 2.3-3.5 cc/cm2/min). The smooth coating contains some SiC. Use of maleic anhydride reduces the polymerisation time considerably over previous methods. The two coatings prepared in this way protect the fuel particles efficiently and are not prone to develope cracks.

Title: Staggered overlapping stacking of sheets
Inventor: VITS HILMAR
IPC: B65H29/68
Filed: 1969-06-20
Abstract: Following sheet region is blown at the boundary surface facing the stack, at the initial region of a first sheet. The following region is deflected from the conveying plane. The deflection is raised and the region is carried over to the sheet end, whose termination forms the last cut edge of the sheet. The first sheet is forwarded in a plane with an initial speed, and the forwarding speed of the sheet is reduced relative to the initial speed of a second sheet, so that the start of the 2nd sheet overlaps the 1st sheet and assumes the location of its end. A region following the initial region of the 2nd sheet is then blown and the cycle is repeated. Sheets are paper, plastics, cardboard or fabric.

Patent DE-2065777-A1 (DE)
Title: Electronic control system for spark erosion machine - generates impulses across di-electric between tool and workpiece
Inventor: INOUE KIYOSHI DR
IPC: B23H7/18
Filed: 1970-03-31
Abstract: The electronic control system depends on the generation of a series of electrical impulses across the gap between the electrode tool and the workpiece. The circuit monitors this gap be means of the threshold discriminators which generate a signal when the thresholds of 20V, 35V and 45V respectively are exceeded. These different thresholds correspond to the state of the di-electric which fills the gap between the electrode tool and workpiece which may be gas or a mixture of gas and liquid or all liquid, depending on operating conditions. The electrical impulses from the electrode tool affect the rate of discharge of the condenser which in turn controls the threshold discriminators.

Title: Vibration sieve - with changing lever ratios
Inventor: SCHLEBUSCH LUDWIG DR-ING
IPC: B06B1/10
Filed: 1971-07-03
Abstract: Vibration sieve for an electromagnetic or mechanical vibrator comprises a drive wheel with an eccentric crankshaft connected to a number of drive levers.

Title: Blow moulding hollow objects - particularly bottles using multiple moulds and blowing heads
Inventor: SETTEMBRINI ANTOINE DI
IPC: B29C49/42
Filed: 1971-08-09
Abstract: In a machine for continuously fabricating hollow objects particularly bottles, from extruded plastic material on a rotating table, a single framework holds two extrusion blowing devices mounted on turntables rotating in an inverse sense and operating as parts of a common disposal system for the moulded objects. The multiple moulds are provided with rollers on curved rails forming complex trajectories to ensure the rapid replacement of the parisons by another mould. The blowing heads above each mould comprise at least two telescopic nozzles to which the bottles are attached, allowing them to describe an increased external path so as to multiply the degassing and cooling time. A device for separating the runners is incorporated in the rotating table and not in the moulds. The extrusion heads may swing between working and blocking posns. The use of a double rotary table with extended cooling trajectories incorporating runner removal increases production.

Abstract: Primary elements, esp., for thermochemical gas analysis apparatus, are made by covering a Pt-spiral with a suspension of Al2O3 in unsaturated Al(NO3)3 and methanol, then a similar suspension using H2O instead of methanol. After each addition the spiral is electrically heated to 600-700 degrees C for 15-20 sec. The treated spiral is then heated to 800-900 degrees C for 12-15 hrs. in a muffle furnace and allowed to cool slowly. A catalytically active coating is then applied using drops of PtCl4 and PdCl2 soln. alternately with electrical heating, as before, after addition of each drop. Finally the element is further heat treated at 800-900 degrees C for 12-15 hrs. The element has homogeneous structure and porosity and gives repeatable results of identical sensitivity.

IPC: C12N9/04
Filed: 1972-05-17
Abstract: A cholesterol-converting microorganism, opt. after washing with butanol-water, is opened up and extracted with a buffer soln. contg. non-ionogenic surface-active agent.

Title: Power hammer actuated by IC engine counter piston - has automatic hammer release for easy starting
IPC: F02B71/04
Filed: 1973-10-25
