Patent CH-649148-A5 (CH)
Title: Fireplace insert for hot-air production
Inventor: MUELLER ERWIN
IPC: F24B1/188
Filed: 1980-09-04
Abstract: A built-in unit with a number of air-heating pipes (3, 4) can be fastened above the hearth (F) of a fireplace in such a manner that the pipes (3, 4) extend transversely through the smoke-gas flow and their outlet ends (4a) open under the upper edge of the firing opening into the room in front of the fireplace. Air, which is delivered by a blower, is supplied through a pipe (7) to the inlet ends (1) of the pipes (3, 4). The air can be drawn from the room and/or from the open. It is heated in the pipes (3, 4) by active heat exchange with the smoke gases and emerges into the room through the outlet ends (4a). This fireplace insert is simple and cheap and can be used in existing fireplaces without rebuilding work. <IMAGE>
Patent CH-659101-A5 (CH)
Inventor: ERB ANTON
IPC: E04B1/21
Filed: 1982-12-01
Abstract: If concrete ceilings (1) are to be connected to walls (2) while maintaining between them expansion joints, dowels (4) have to be inserted. As the steel pins (5) and the bushings (6) have a round cross-section and as they can transmit without causing damages nothing but relatively small loads to the concrete surrounding them, the steel pins (5) as well as the bushings (6) are interconnected by junction plates (7, 8), thereby implying an increase of the bearing surfaces. Important loads may thereby be transmitted without damages to the concrete elements through a dowel (4). A front plate (9) connected to the sleeves (6) further facilitates the mounting of the dowel (4) in the cofferings by enabling its nailing to the latter.

Title: Voltage zero transmitter for high voltage
Inventor: TRAVIN LEV VIKTOROVICH
IPC: G01R19/175
Filed: 1977-07-19
Abstract: The transmitter, which, in particular, is used for controlling a light-emitting diode at the input of an optical connecting channel between high voltage and earth potential for controlling high-voltage thyristors, contains a resistor voltage divider with a rectifier and a limiter with Zener diodes. The base of the transistor (13) of a blocking oscillator is connected to one of the input terminals (31) of the rectifier by a capacitor (39). In parallel with the output of the rectifier, a storage capacitor (34) and two series-connected capacitors (37 and 38) are connected, the series-connected capacitors (37, 38) being bypassed with Zener diodes (35, 36) of the limiter. The common point of these diodes (35, 36) is connected to the emitter of the transistor (13) of the blocking oscillator, the latter being connected to the output of the rectifier via a dynistor (23). This transmitter does not require any separate active element for controlling the light-emitting diode. The operation speed of this transmitter is relatively high and there is no uncontrollable operating threshold. <IMAGE>

Patent CH-628138-A5 (CH)
Inventor: CELIO TINO
IPC: G01C3/10
Filed: 1977-10-06
Abstract: A process and a device for measuring a distance are described using an opto-trigonometric arrangement and a photoelectronic positioning determination. The target (2) is irradiated by means of light radiation (S<u1>u) and the impact point (T<u1>u) is optically represented on a linear photodetector (5) by means of an oblique angle (B) to the irradiation direction. The spatial position (d<u2>u) of the impact image is determined by means of an electronic scanning by the photodetector and from there, the distance (D<u1>u) from the target is measured by means of trionometric relations. Preferred alternatives are specially intended for measuring short distances and hollow profiles.

Patent FR-2063307-A5 (FR)
Title: Bread-making device for bakeries
IPC: A21C3/04
Filed: 1969-09-03
Granted: 1971-07-09
Abstract: Device is intended for the automatic manufacture of breas or similar products from the moment the dough is prepared until it is placed in the oven. It comprises a number of rolling devices each of which consists of three conveyor belts; the base belt has a higher speed than that of the two lateral belts. These rolling devices are superimposed to reduce the space occupied by the machine. The dough, fed from a vessel with a controlled outlet, falls on the elongation rolling device and then to a weighing machine; this actuates a cutter to divide the srip of dough at definite intervals. The loaves are then fed to an evacuating conveyor and may undergo further rolling to receive a precise and ideal shape. The operations are effected in one machine whereas previously two machines were required. Loaves of different dimensions can be made by adjusting the feed control device.

Title: Cheese prodn plant - suitable for mfr of cheese of various types
IPC: A01J25/00
Filed: 1970-12-15
Granted: 1972-07-28
Abstract: Plant is of the type which comprises a tank in which the milk is left to curdle; the curd obtd. possibly fragmented, is then poured into the moulds of a multi-mould plate. The tank is hemi-spherical in section and has an extraction assembly for the curd. When the curds are ready to be poured, the extraction assembly, is brought over the tank and jacks are operated in the downward direction to bring the arms of the extractors into the mass of curds and divide the latter into a number of compartments of equal vol. When one of these arms is rotated by a motor it pushes the curds to the level of a gutter from which it goes either directly to the moulds or to a draining appts. The extraction assembly ensures the simultaneous division of the curds into equal vols. before their transfer into the moulds.

Title: Cleaning device for gratings - of water intakes
IPC: B01D35/28
Filed: 1971-01-26
Granted: 1971-10-15
Abstract: Cleaning device is intended for the gratings at the water intakes at hydroelectric and waste water purification stations; it is of the type comprising a driving motor mounted directly on, or in a movable combing arrangement which co-operates, through a pinion of gearing, directly with the guide racks, which are parallel with the bars of the grating to be cleaned. The cleaning comb or rake is advanced between the bars in the upward direction and is fixed on a box housing the motor. The comb is guided by this box and by upper and lower guide rollers along an external and an internal guide which are connected together. The comb is pivoted in the direction of the grating, as it continues to advance, and its teeth penetrate between the bars. Solid matter caught up by the comb is tipped into an evacuation drain at the top of the device. The latter assures the easy guidage and return of the comb whilst completely cleaning the greating.

Title: Semi-mechanical handling of asparagus shoots - by rotation in circular holder from cutting to washing positions
IPC: A23N7/04
Filed: 1971-09-14
Granted: 1972-04-28
Abstract: Machine is intended for cutting to length, washing or burshing gauging and bundling asparagus. The machine consists of a ring fited, on its periphery, with compartments with base closing systems operated by axes and levers, a circle, integral with the lower part of the compartments supports the ends of the shoots. By rotating the assembly the prod. passes successively from the cutting to the washing position, the speed of the ring being set according to the dexterity of the operator. The shoots are cut to the desired length by a circular saw, with special teeth, placed below the ring. The shoots are next washed by upper and lower rows of jets of water under pressure. At the next position the shoots are gauged and graded for size into three classes: 12-15 mm, 16-24 mm, and above 25 mm. Washing and brushing is efficient because the shoots are supported at only two small points; gauging is perfectly regular as it is effected at the ends of the shoots.
