Patent CH-600928-A5 (CH)
Title: Pressure or vacuum filter with a paddle arm
Inventor: TRUB JACQUES
IPC: B01D29/075
Filed: 1977-01-04
Abstract: A filter assembly comprising a vessel with a filter element across the bottom.  The assembly includes a horizontal paddle arm, which may be displaced vertically, mounted on a shaft and driven by a motor. The paddle arm fulfills two functions. Firstly, when rotating in one direction, the paddles smooth the top of the filter cake, thus preventing the appearance of cracks.Secondly, when rotating in the reverse direction and simultaneously being lowered into the cake, the paddles act as scoops to remove the cake at the completion of the filtering operation.The continuous smoothing of the cake with the resultant elimination of cracks facilitates the maintenance of the pressure difference across the cake, which is necessary for efficient filtration.  The assembly provides an efficient mechanical handling device for the removal of the cake when filtration is complete.

Title: Fermenter and process for the continuous anaerobic biodegradation of waste waters
Inventor: GOOD PETER DR
IPC: C02F3/28
Filed: 1982-04-16
Abstract: The fermenter is used for the continuous anaerobic degradation of waste waters with the production of biogas and consists of a plurality of compartments (6) which are arranged in succession (in the direction of flow of the waste water through the fermenter) and which are filled with the liquid to be degraded; the liquid level therein decreases from compartment to compartment. The liquid flows, or is advantageously pumped, through all the compartments. Each compartment is equipped with supports (7) which are colonised by the anaerobic bacterial strains, and with other devices. The supports preferably represent synthetic, specifically polyethylene terephthalate, fibre material which is advantageously processed to nets or the like. The clarified water is drawn off downstream of the last compartment (9). The biogas is advantageously likewise drawn off in the vicinity of the point where the clarified water flows out (8).   The advantages of the fermenter according to the invention and of the process according to the invention for waste water purification using this fermenter are:     concentration gradient (decreasing in the direction of flow),   plug flow,   immobilisation, uniform gas solubility throughout the fermenter because of the restricted height, improved possibility for monitoring the entire system because of the multicompartment system, large off-gas area, operation at 35 DEG C or 50-70 DEG C.   <IMAGE>
Patent CH-642998-A5 (CH)
Title: Process for chemically heating a steel melt
IPC: C21C5/00
Filed: 1979-03-23
Abstract: In chemical heating of a steel melt, which has previously been brought to a defined carbon content by refining, it has been usual to add an agent giving a highly exothermic reaction. To avoid volcano-like eruptions, the agent is added to the melt in a quantity greater than that required for reaching the end temperature. At the same time, gaseous oxygen is fed in.
Patent CH-656997-A5 (CH)
Title: Speech device for installation in a crash helmet for vehicle users, in particular motor cyclists
Inventor: KRAUSS RALF
IPC: A42B3/30
Filed: 1982-05-21
Abstract: Switching components of the speech device (6), an earpiece (10), a microphone (11) and two electromagnets each comprising a winding and a rod-shaped soft-iron core (20, 25) are disposed on a printed circuit board (7). The printed circuit board is bent in such a way that it can be installed between the inner wall of a casing (2) and a pad (5) of a crash helmet (1). A speech switching device for automatic changeover from the reception mode of the speech device to transmission mode when the speech signals generated by the microphone (11) reach or exceed an ideal value, is also provided on the printed circuit board. During transmission mode, a transmission stage is enabled, whereas a receive amplifier is blocked. During reception, the transmission stage is blocked and the receive amplifier is enabled. The speech signals are transmitted directly via the stray field of the aforementioned electromagnets so that no RF signals are radiated. Since the speech device (6) installed in the crash helmet (1) is adequately protected by the latter, there is no need to provide a special housing for the speech device (6), thereby substantially reducing the manufacturing costs of the latter. <IMAGE>

Patent CH-584981-A5 (CH)
Title: Proximity switch with two capacitative sensor plates - is activated by imbalance in outputs of two HF oscillators coupled to comparator
IPC: F16P3/14
Filed: 1975-05-23
Abstract: The proximity switch consists of two HF oscillators (KA1, KA2) with their tuning circuits connected to two capacitive sensors (S1, S2) mounted on the switch's plastic housing (1). The outputs of the oscillator are rectified and compared to produce a trigger signal when the operator's hand or finger approaches the sensors and alters the capacitance in the two tuning circuits. This unbalances the outputs of the oscillators. The sensors consist of parallel wires or metal strips. The arrangement can be used to switch off machine tools when the operator's hand enters the work area.

Title: Process for manufacturing a multilayer element making it possible to obtain overlaid images visible one at a time at a specified temperature
Inventor: CALANCHI MASSIMO DR
IPC: G02F1/133
Filed: 1977-11-01
Abstract: The process consists in applying to a substrate, for example by silk-screen printing, different overlaid layers of liquid crystals, each layer exhibiting the shape of an image from the sequence which it is wished to display. Each layer consists of a mixture of liquid crystals which changes colour at a temperature which differs from that at which the other overlaid layers change colour: the substrate is then warmed. With the progressive warming of the layers a sequence of images (as for example illustrated in the figures) is obtained which are rendered visible in succession one at a time to the observer. The invention is of particular use in the field of teaching, education and recreation. <IMAGE>

Title: Yarn feed device - using rotating drive cylinder between two yarn guides
IPC: B65H51/08
Filed: 1971-06-07
Granted: 1973-01-19
Abstract: Yarn is fed to e.g., a knitting machine by contact with a driven roll arranged between a pair of yarn guides, and the roll has a circumferential channel in which the yarn seats, the bottom of the channel being covered with a high friction material and the sides of the channel being smooth. Pref. the roll has several such channels for guiding several yarns and the yarns pass over this roll and under another similar roll in a serpentine path between the guides. The two rolls may be mounted on a common support which is rotatable to bring the rolls into and out of contact with the yarns. Each roll may be formed by a rubber covered cylindrical core carrying axially spaced polished metal rings between which the channels are defined. The channels prevent the yarns from moving axially along the roller, thereby preventing an increase in their travel path and tension, and reducing the possibility of breakage.

Title: Reproducing oil paintings - by moulding a colour print on film against a profiled plastic copy
IPC: B44C3/04
Filed: 1971-09-23
Granted: 1973-05-04
Abstract: In a process for reproducing an oil painting a colour print is made on a thermoformable film using colour sepn plates. The film is attached to a paper base and may then be formed against a plastic reproduction of the profile of the paintings, the paper backing being removed. After moulding the film is provided with a backing. The film on which printing takes place is very thin but is supported by a paper base which is removed before moulding the film to against a plastic profile of the painting. The film is pref. formed using a film-forming polystyrene emulsion, by applying it to a paper base by a silk screen process. The film is inserted in a frame and the paper base removed. A matrix may be formed by moulding an elastomer against the painting and then moulding the colour print film against it, interposing a thin layer of a silicone release agent, so that after removal of the film and cooling, a suitable backing e.g. of PVA emulsion, can be applied to it.
