Title: Wide angle television tube pin-cushion corrector - uses a frame parabola injected into scan current
IPC: H04N3/233
Filed: 1974-03-26
Abstract: This pin-cushion corrector consists of a transformer with four windings. The line-scan coils are connected across two windings in series (L1, L2). The line-scan causes sawtooth currents to flow in the windings which are induced into the third winding (L3) which is connected across the frame-scan coils thus modulating the scan waveform. The frame-scan induces frame sawtooth currents into the line circuits giving frame modulation. To provide the extra correction for wide angle tubes, a frame parabola is generated (17) and its polarity during the frame time is reversed by two semiconductors. This correction waveform is injected into the fourth winding.

Title: Rubber or elastomer sealing strip for door or window - has spring plate inlay in sealing lip and slotted mounting base
IPC: E06B1/34
Filed: 1974-08-09
Abstract: The spring plate inlay extends at one end nearly to the tip of hte sealing lip and at the other end emerges from the rubber or elastomer strip to form a U-shape with parallel limbs. One limb forms a support for the sealing strip while the other, outer lying limb presses against the stop surface. Thus the U-shape effectively bridges the intermediary gap between the metal profile and of the window and the surface against which it is to be sealed. The slotted base of the strip is located in a channel in the metal profile. The strip has serrated sealing edge whose tips press against the stop surface.

Patent FR-2265488-A1 (FR)
Title: Non cutting thread tap - has square section shaft ground to ellipse able to roll material in hole
IPC: B23G7/02
Filed: 1975-03-25
Abstract: The tap is made from a square shaft section, with the corners well rounded while the sides bulge out. During mfr. of the tap, the grinding wheel which cuts the thread in the tap moves in and out to follow the circumference of the section. After the thread is cut, a thin grinding wheel with narrow cylindrical face is used to grind the tip of the thread and to grind the whole depth of thread away over part of the circumference of one thread so that the thread extends in one direction only. This part of the thread is rounded so that the part of the thread that remains is in the shape of the end of an ellipse. Each consecutive protruding part of the thread is off-set from the previous section by 90 deg. The part of the thread that is ground away ensures that there is room for the material that is being displaced when the tap is screwed into the hole.
