Patent CH-685217-A5 (CH)
Title: Process for the machining of boards (plates) and machine for carrying out the process
Inventor: ZUMSTEIN ERNST
IPC: C03B33/037
Filed: 1992-05-07
Abstract: By means of sensors (10, 11, 12), the position and shape of the edge of a board (2) to be machined lying in front of these sensors is registered. The signals from the sensors are fed to a control unit (9) which has a program for controlling a cutting head (7) or another machining tool. On the basis of the signals, a computer determines the position and shape of the board (2) and transforms the control program in such a manner that the cutting head (7) places the cutting line or cutting lines in the correct position on the board (2). It thus becomes unnecessary to position the board (2) very accurately on the cutting table (1), which allows considerable simplification. <IMAGE>

Patent CH-578298-A5 (CH)
Title: Fluorescent lamp operating circuit - has single transistor with first primary winding as collector load and second primary coupling base to RC element
IPC: H05B41/282
Filed: 1973-02-19
Abstract: The fluorescent lamp operating circuit is intended for a direct current system and has a single transistor connected between the direct current supply poles and with its collector load formed by a transformer second primary winding. The transformer secondary winding is coupled across the fluorescent lamp. The base of the transistor is coupled over the first primary winding to a series RC element that is also connected between the direct current supply poles. The advantage of using a single-transistor circuit as described lies in its allowing a balanced supply and in increasing the lamp service life by reducing the number of starting attempts.
Patent CH-661342-A5 (CH)
Title: Self-loading pistol
Inventor: REPA OTTO
IPC: F41A35/06
Filed: 1983-05-11
Abstract: The self-loading pistol has an operating lever (10), which can be operated by the thumb on the firing hand and is used both to uncock the firing hammer (1) and to release a breech holder (25) which locks the breech (24) in the open position. In order to make it possible for left-handed personnel to operate the operating lever (10) without modifying the pistol, the operating lever (10) is firmly connected (by means of a transverse shaft which is supported in the grip (2) of the weapon such that it can pivot about a [lacuna] which is transverse to the firing direction) to a second operating lever which is arranged on the other side of the pistol. A right-handed person releases the breech holder (25) by pressing down the left-hand operating lever (10), and a left-handed person releases it by pressing down the right-hand operating lever, and the firing hammer (1) is uncocked by pressing the operating lever (10) down further. <IMAGE>

Patent CH-646202-A5 (CH)
Title: Multi-part carbon electrodes
Inventor: LIST HEINZ DIPL-ING
IPC: C25C3/12
Filed: 1981-08-17
Abstract: Manufacture of carbon electrodes, e.g. as anodes in aluminium electrolysis, from a plurality of parts whose smaller cross-sections permit a more rapid and more economical firing cycle than would be possible for block anodes in one piece, the suspension and power- supply parts being arranged between the carbon parts. The block anode shown in Figures 4, 5 and 6 as an example is composed of the two parts (20 and 21) whose cross-section relevant for the firing cycle is only half the size of a block anode in one piece. The two parts (20 and 21) are held together by the clips (24, 25) with screw (26), or (26, 27) with screw (29), respectively. Suspension is effected in a conventional manner from two rods (22, 23) which also serve for the power supply. The bipartite structure of the anodes permits, as a further advantage, the suspension rods to be constructed with a support flange (30, 31), a tamping or potting composition normally being introduced between the rods and the carbon composition to achieve better contact. <IMAGE>

Abstract: PCT No. PCT/CH80/00069 Sec. 371 Date Feb. 12, 1981 Sec. 102(e) Date Feb. 9, 1981 PCT Filed Jun. 10, 1980 PCT Pub. No. WO80/02883 PCT Pub. Date Dec. 24, 1980.This device comprises two pairs of superimposed pick-up coils 1, 2, 5, 6. Each pair is formed by two windings coupled in series but with opposing winding directions, each winding of one pair having a layer of rectilinear conductive portions 1a, 2a, 5a, 6a side by side parallel to and superimposed on the similar portions of the other winding. These two windings extend on either side of their superimposed layers respectively. The superimposed layers of one pair of windings are orthogonal to those of the other pair. This arrangement is intended to induce in each pair of coils, under the influence of a permanent magnet having a flux approximately perpendicular to these windings, fluxes which add up when the inductive flux varies in a plane parallel to the coils and which are cancelled when the inductive flux varies perpendicularly to this plane.

Title: Basketball toy
Inventor: MITIC MILUN
IPC: A63F7/06
Filed: 1982-12-18
Abstract: The toy comprises a hollow parallelepipedal body (1) including two compartments (2, 3) intended for accumulating and guiding balls (13, 14) in a vertical channel formed of two offset parts (5, 20) connected by a dispensing slide (16). A ball-return member (8), integral with a support (7) mounted slideably across the channel (5) makes it possible to close the latter off. An elastic lever (34) makes it possible to project a ball (65) vertically over the guide means (66) which bring it back above a basket (47). Using means (43) arranged above the latter, the player can prevent the ball from pentrating therein by sending it onto the return member (8). The toy may also be used for teaching addition and subtraction operations in an entertaining manner. <IMAGE>
Patent CH-572219-A5 (CH)
Title: Measurement and indication of electrical signal - has logarithmic dependence for large dynamic range
IPC: G01D3/02
Filed: 1974-09-06
Abstract: The instantaneous values of the signal are successively scanned and passed to a store. By comparison with a reference pulses of a timed duration are formed in an approximate logarithmic dependence on the signal amplitude present at the time. The instantaneous values of the signal are successively scanned and passed to a circuit (R, C, V) which serves as a store and contains a capacitor (C). The voltage of the capacitor (C) which reduces during the unloading, triggers the trip action of an operational amplifier (V) if it drops below a reference voltage. As a result a pulse is formed of a timed duration in approximate logarithmic dependence.
Patent CH-614543-A5 (CH)
Title: Apparatus for giving information intended for a perfume
Inventor: OURY RAOUL-PIERRE
IPC: G06G1/00
Filed: 1974-10-15
Abstract: On a flat support (1) are arranged at least two closed lines, homothetic of one another (A, C). The first line (A) includes a distribution of the categories of the characteristic odours (1 to 14), the latter being classified so that each odour inscribed is subdivided by bearing on the two adjacent characteristic odours. The second line (C) includes a distribution of the aesthetic categories, the latter being classified so that each aesthetic category resembles or is similar to each of the two aesthetic categories which are adjacent to it. The cyclic principle applied to the categories of the odours is kept for the aesthetic categories. The position of n poles of vital food odours is indexed on the first line and the position of n large categories of sensitivity, revealing the specific psychological states, is indexed on the second line, the two lines being placed opposite one another so that one of the two lines is inside and homothetic of the other line. The n sensitivity categories of the second line are arranged in correspondence with the resonance areas of the n vital food odours of the first line, each of the n resonance areas corresponding to one of the n sensitivity categories, and conversely. An indexing device (6, 7, 8) of the position of p aromatic components of a perfume makes it possible to determine, by simple correspondence, the p main aesthetic categories of the person for whom the perfume would be best suited. The device is produced in the form of a p-sided deformable convex polygon, p being at least equal to 3. <IMAGE>
