Title: Electric generator driven by sonic power - employs ionised inert gas oscillating in magnetic field and has vacuum jacket around to damp out noise
Inventor: FEIFFER ALBERT
IPC: H02K44/08
Filed: 1976-12-31
Abstract: The generator comprises an electromagnet (EM) in whose gap there is a sealed tube (Rg) split longitudinally in a vertical plane. Each half tube is electrically isolated from the other (1). A sonic generator (S1, S2) is mounted at each end of the tube, and the tube is filled with an inert gas (Gi), typically argon, which is ionised, for example by ultraviolet radiation (UV). The tube halves form anode and cathode and are taken to external connections (Uk). The sonic generators are excited at a low frequency, one in antiphase to the other, causing the gas to oscillate in the tube. In doing so it cuts the field set up by the separately excited magnet (EM) thus giving an output at anode and cathode. The structure is surrounded by a vacuum jacket to damp out noise radiation.

Title: Plank sawing lateral guidance system
Inventor: TOUMAALA JORMA AARNE KULLERVO
IPC: B27B1/00
Filed: 1977-01-07
Abstract: The lateral guidance system is for steering timber planks or beams while they are being worked. Lengthways grooves are previously applied, for engagement by guiding battens (5), while forwarding takes place. A lengthways groove (4) is produced in the underside (2) of the plank (1), which has already been worked smooth. - For subsequent removal of the groove, the plank is sawn lengthways along the groove, with a cutting area at least equal to the width of the groove. The groove may be made on the centre line, less than 3 mm wide, and less than 10 mm deep. The groove cutter is fitted in the same lateral position as the saw and the saw cutting width is at least as great as the groove width, so that its cross-section covers it. Timber wastage is unaffected by the lengthways grooves, and they do not affect the shape of cut.

Title: Capacitor with two end caps - has rounded edge of each cap forming curved surface towards cap outer envelope surface
Inventor: KAERNER OTTMAR ING GRAD
IPC: H01C1/148
Filed: 1977-10-28
Abstract: The capacitor has the two terminal caps fitted to the two ends of an electric insulating support. It is protected against ambient effects by a sleeve forming a layer round the assembly. The edge (23) of the cap is rounded in such manner, as to form a curved surface in the direction of the outer envelope surface (21) of the cap (2). The rounding (25) of the cap edge is preferably such that the curve towards the outer envelope surface is longer than that to the inner one (22). This configuration serves to aid a uniform cover of the capacitor by the protective layer, thus excluding air pockets under the cap edges. This increases the breakdown voltage of the capacitor and protects it against ingress of moisture.

Title: Twin-beam infrared gas analyser - with tilting interference filters to minimise interference effects of other constituents
Inventor: DEPTOLLA UDO ING GRAD
IPC: G01N21/37
Filed: 1978-01-27
Abstract: A two-beam infrared gas analyser has a chamber in each beam path contg. specimen gas. In the first beam path there are two successive chambers contg. the gases be analysed, but in the other beam path there is only one such chamber. The pressure difference between the second chamber in the first parth and the single chamber in the second path is measured, and the pressure fluctuations as the infrared beam passes intermittently through the chambers are converted at a diaphragm condenser into electric signals. To compensate the transverse sensitivity in the beam paths upstream of the chambers tiltable interference filters are disposed in each path. These each have an absorption limit in the overlapping spectral range of the absorption band of the measured component and the absorption band of the disturbing component and in their pass range in the remaining absorption range of the measured component. Pref. the chamber is connected via a high pneumatic resistor to one of the other two chambers. A typical use is in the measurement of NO in automobile exhaust gas; it is found that the disturbing influence resulting from the accompanying gases CO, CO2 and H2O is eliminated by the above appts.
