Title: Cutting tool for making cardboard box blanks - uses multi stage photographic reproduction techniques for forming matrix for punch
Inventor: SPENGLER ERNST MAXIMILIAN
IPC: B26F1/44
Filed: 1975-10-15
Abstract: A cutting tool for making blanks for carboard boxes, contrary to the usual practice, includes the matrix (25) in addition to the punch (8). The method uses multi-stage photographic drafting techniques to produce a matrix of the desired precision. Initially a tracing showing the fold positions in basic dimensional outline is drafted. From this basic tracing a film indicating cutting edge positions is obtained and used to locate the cutting edges (32) on the punch (8). By inverse reproduction, negatives for punch projections (20) and matric grooves (21) are then obtained from the basic tracing. Precise groove and projection widths are shown on these latter negatives. The negatives are then used to produce punch projection and matrix groove films. Finally the punch and the matrix are obtained by insulating photo sensitively coated plaques with the films interposing.

Title: Plastics nut for furniture - has thin unthreaded base plate connecting split halves allowing flexure and radial expansion
Inventor: TUCHIKAWA ZENJI
IPC: F16B37/08
Filed: 1975-11-26
Abstract: The expansible/compressible nut for furniture construction is made of thermoplastics, e.g. polythene, and has an axial tapped bore (12) and a diametral slot extending almost throughout its depth. This leaves a thin connecting section (16) between the two halves. The nut is used for a bolt through a drawer front surface, and can deform by flexure of the thin base into a convex shape, allowing the nut to expand radially. This allows the nut to be shifted along the bolt without rotation, since there are no threads on the bore surface in the thin base region.

Title: Generator speed controller operating by electric load adjustment - achieves control by varying relative positions of generator stator and rotor
Inventor: HEUBECK JOHANN DIPL ING
IPC: H02K7/12
Filed: 1976-09-17
Abstract: To achieve full utilisation of available energy in hydroelectric and, more particularly, in wind powered generating plants it is proposed to regulate the turbine speed to the required value by regulating the electrical load directly. This is achieved by having a multi-machine unit with a common drive shaft (1) coupling all the rotors (3) together. The corresponding stators (2) are axially moveable in guides and on rails, and the number of stators which are fully linked with their rotors is determined by the available energy. The automatic control system regulates the shaft speed to the desired value by adjusting the stator position of the various machines until the input and output energy are balanced. Regulation of turbines is thus avoided and full use can be made of the available wind or water flow.

Title: Subterranean gasification of coal - using matrix of bore-holes for charging gasification agent and discharging prods., minimising costs
Inventor: WENZEL WERNER PROF DR ING
IPC: E21B43/30
Filed: 1977-07-06
Abstract: The subterranean gasification of coal incorporates defining the limits of the coal masses in layer by imaginary lines and offsetting the boreholes, by which the gasifications agent is introduced and by which the gaseous products are discharged, w.r.t. the coal front at which the reaction is taking place, in the direction of progression of the gasification. The corresp. feed and discharge holes are at a distance from one another in a direction perpendicular to the progression of gasification, so that the gasification agent circulating from one to the other is in contact with the coal mass. The gasification agent is e.g. air, O2, H2, CO2 and/or steam. The costs of preparing and exploiting the coal layer are minimised. Gasification is possible independently of the disposition and thickness of the layers, and in the case of horizontal as well as inclined layer. A less dense system of pipes is needed than with other installations; the surfaces are less covered and can be used for agriculture. Gasification under high press. e.g. 10-60 bar is possible and gives good contact, partic, useful in the case of coals which are difficult to gasify.
