Patent CH-637615-A5 (CH)
Title: Process for separating naphthoquinone and phthalic acid
Inventor: MATSUURA RYO
IPC: C07C46/10
Filed: 1978-01-09
Abstract: A process is provided for separating naphthoquinone and phthalic acid from an aqueous suspension. The latter is obtained by contacting a mixed reaction gas, which is obtained in the catalytic vapour-phase oxidation of naphthalene, with an aqueous medium, decomposition of the naphthoquinone being prevented and the phthalic acid being substantially completely separated off by addition of a base to the aqueous suspension. At this stage, only the sulphuric acid component and the maleic acid component are neutralised, while the phthalic acid component is substantially not neutralised. The aqueous suspension is heated in order to dissolve the phthalic acid, so that a suspension of naphthoquinone in an aqueous solution of phthalic acid is obtained. The naphthoquinone is then extracted with a solvent, and crystallisation of the phthalic acid is prevented. The pH of the aqueous suspension is adjusted to a value in the range from 1.2 to 2.5 before the phthalic acid is dissolved hot and the naphthoquinone is extracted. The aqueous phase obtained after the extraction of the naphthoquinone is cooled in order to crystallise the phthalic acid out. The filtrate separated from the resulting suspension serves as an aqueous medium for contacting with the mixed reaction gas, if appropriate after adjusting the pH to the range from 1.2 to 2.5.

Title: Drum for raising and lowering venetian blind - using two part drum which pulls down as well as up
Inventor: LUCHSINGER HANS JOERG
IPC: E06B9/32
Filed: 1986-07-31
Abstract: A Venetian blind is raised or lowered by means of a cord (8) which passes through the slats. The cord passes around a pulley mounted on the lower edge of the window frame and the ends of the cord are wound onto different parts of a common drum (12). The drum has an external screw thread (13) which forms a guide groove for the cord (8). The ends (80,81) of the cord are wound onto the drum in opposite directions, so that as one end is wound up the other end is payed out. The blind is thus pulled down as well as pulled up. The blind can be used with sloping windows where frictional contact between blind and window hinders the free descent of the blind. USE - Venetian blind.
Patent CH-658340-A5 (CH)
Title: Circuit arrangement for driving a relay by means of push buttons which are illuminated by glow lamps
Inventor: ZETTING ALOIS
IPC: H05B37/02
Filed: 1982-07-29
Abstract: In this circuit arrangement, a non-linear resistor (RNL) whose cold resistance value is small in comparison with the resistance of the relay winding (2), is connected in parallel with the winding (2) of the relay (1) which can be driven by push-button contacts (51....5n) having associated glow lamps (6). Therefore when the push-button contacts (51....5n) are open, only a small proportion of the glow lamp current flows, as a quiescent current, through the relay winding (2), so that the relay (1) is with certainty not excited. When one of the push-button contacts is closed, the non-linear resistor (RNL) assumes a hot resistance value which is 10 to 20 times higher, and the relay (1) is excited (energised) in order to switch the lamps (41.....4m) on. The cold resistance value can be selected to be as small as desired, possibly by connecting PTC thermistors in parallel, so that even in the case of a large total current for all the glow lamps (6), the permissible quiescent current limit is not exceeded. Virtually any desired number of illuminated push-button contacts can be connected in the exciter circuit of the relay without having to worry about erroneous switching operations. All-purpose incandescent lamps (9) are preferably used as the non-linear resistors, which are particularly advantageous in the event of damage, with respect to costs, ease of procurement, life and replaceability. For example, fitted with a 100 W incandescent lamp, up to 80 illuminated push-button contacts having 2 mA glow lamps can be connected to a 3.7 k OMEGA  relay with full switching safety. <IMAGE>

Patent CH-645193-A5 (CH)
Title: Picture carrier
Inventor: BAUR MAX
IPC: G09F11/30
Filed: 1983-09-12
Abstract: In order to hold a picture, this picture carrier (301) has a peripheral gap (313) between a frame (302) which bounds the viewing face and a rear wall (303), which gap (313) is open to the outside on one side of the picture carrier. In a recess (329) of the rear wall (303), a flat support (304) is arranged which can be pivoted out of the rear wall (303) about a side edge (330) and can be locked in any desired pivot-out position. A transport roller (342) which is arranged at the free end of the support (304) so as to be manually rotatable rests near to the gap opening, against the inside of the frame, when the support (304) is pivoted in so that by rotating the transport roller (342) a picture which is inserted into the opening can be drawn into the gap (313) or a picture can be pushed out of the picture carrier. Holes (309, 310) present in the rear wall (303) serve to enable the picture carrier to be hung up. The picture carrier ensures particularly simple changing of pictures and can be set up in a stable fashion on the longitudinal and lateral side at any desired angle of inclination or can just be hung up in a flat state; additionally, it can be manufactured economically using a small amount of material and, by virtue of its design can itself be dispatched for example as a letter. <IMAGE>

Title: Circuit for turning off a DC regulator
Inventor: HENNEVIN BERNARD
IPC: H02M3/135
Filed: 1977-11-10
Abstract: The effect of the circuit is a more rapid return to the blocked state of the main thyristor (Th1), the latter being used as a DC regulator, whose time for recovery of the blocking capability does not need to be very short. This is achieved with an increase in the amplitude and the duration of the inverse bias of the voltage (V2 + V3 + V4) of this thyristor. To turn off the main thyristor, a turn-off thyristor (Th2) is rendered conducting. This thyristor (Th2) is mounted in parallel with an inductor (L1) and a capacitor (C1), the capacitance of which can be relatively small. This circuit forms with a diode (D2) in series a circuit in parallel with the main thyristor. In another circuit in parallel with this main thyristor is mounted a resistor (R1) in series with a diode (D1). <IMAGE>

Title: Device and method for determining the launch point of a ski jumper
Inventor: SCHMALL KARL-HEINZ
IPC: G01S17/74
Filed: 1976-12-13
Abstract: The length of a ski jumper's jump is determined with a device comprising a wave-radiating unit which can be attached to the ski jumper or his equipment, a control device to control the waves at the moment of launch and a device to identify the wave-radiation location or the position of the ski jumper. With this device, the position of the ski jumper is continuously determined, at least in the final part of the jump. Furthermore, the moment when the ski jumper lands is determined and the position of the ski jumper at the moment of landing is stored and displayed. The transmitting device (14) on the ski jumper's skis (13) emits a brief, sharply focussed infrared flash, for example at the moment of launch. The light beam strikes the receiving device (5), the position of which is accurately defined in relation to the length of the ski jumper's jump. In this way, the length of the jump can be accurately determined to within a few centimetres. <IMAGE>
