Title: Recovering pure glycofrangulins - from rhamnus frangula by selective solvent extraction
IPC: C07H15/244
Filed: 1972-02-15
Abstract: Process for recovering glycofrangulins from crude plant material, esp. the dried bark of the alder buckthorn (Rhamnus frangula L.) comprises extracting the material with a solvent mixt. of (i) a 1-3C alcohol and (ii) a 3-6C aliphatic or cyclic oxo and/or oxido cpd.; removing impurities from the extract by adsorption onto an activated polyamide; treating the purified soln. with a non-aqueous, esp. methanolic, soln. of an alkali hydroxide to produce a salt which is then treated with an acid or ion-exchanger, and solvent removed from the final product in the usual manner. Extract is a mild laxative. Process gives a purer product (90-95% consisting of molecules having at least 2 sugar residues bound to emodin) than prior art processes. Extraction solvent has excellent selectivity; most of the impurities (which are foul smelling and cause undesirable side effects) are irreversibly bound to the polyamide, and the process is suitable for large scale operation.

Patent CH-684373-A5 (CH)
Title: Device for injection (input coupling) of microwaves
Inventor: HEIERLI JAKOB
IPC: H05B6/70
Filed: 1992-10-29
Abstract: The device consists of a waveguide (2) which is coupled to a microwave source (3) and has one or more coupling elements (4, 5) using which microwaves can be injected into an application volume (1). The coupling elements are disposed and arranged so that waves coming from the source (3) generate circular-polarised waves in the application volume (1). If these waves are reflected in the application volume (1) and coupled back through the coupling elements (4, 5), they generate in the waveguide (2) waves which propagate away from the microwave source (3) towards an artificial load (6) where they are absorbed. These measures produce the effect, with simple means, that energy radiated back from the application volume (1) cannot leak back to the microwave source (3) where it would lead to undesired heating. <IMAGE>

Patent CH-664548-A5 (CH)
Inventor: LUNARDI GERHARD
IPC: B66B23/12
Filed: 1984-08-22
Abstract: In escalators or moving stairways there exists, between the moving step and the fixedly positioned skirt guard, a latent risk of entrapment or catching of the shoe of the passenger, especially when wearing light footwear. The inventive warning devices are arranged at the side uprights or plates of the step of the escalator and induce the user or passenger, by means of a physically and, possibly additionally, by means of an acoustically perceptible signal, to leave the stepped-on danger zone. Each of the warning devices comprising, for example, two swivelingly or pivotably mounted segments is held in a projecting readiness position, through the force of a spring, in relation to the tread surface and the front surface of the step. When the warning device is stepped upon by the passenger, this warning device is pressed into a flush position with respect to the tread surface of the step and in which position a pin, positioned on one of the segments, is pressed against a profiled guide edge of the related skirt guard. The pin thus glides over the profiled guide edge, during the movement of the step, and causes the step to vibrate. Depending upon the shape of the profiling of the guide edge, an additional acoustically perceptible sound or clatter can be generated.

Title: Construction of volume chamber for hydraulic turbine - for large scale power plants embedded in concrete uses circular cross sections
IPC: F03B3/18
Filed: 1973-11-13
Abstract: The volute chamber has a mainly circular cross-section formed by the shell (15) and the side plates (10) and (11) which are welded to the rings (8) and (9). The rings (8) and (9) are bolted by their end flanges to the end plates (3). Before the concrete is poured the rings (8) and (9) are joined by a temporary ring which may be welded or bolted in position. After the concrete has set this temporary ring is removed leaving a rigid structure into which the turbine can be installed. This method of construction reduces the amount of material required to construct the volute chamber and if required the shell (15) may be dispensed with.

Title: Current-pulse generator - has transistors collector-base acting as Zener diode connected across higher voltage lines with capacitor
IPC: H03K3/335
Filed: 1973-11-22
Abstract: The current-pulse generator consists of a silicon transistor (3) connected over a collector resistor (5) and emitter resistor (4) between two lines (approx. 220V). The transistor's base is connected via a base resistor (6) to its emitter. A first capacitor (7) bridges the collector resistor. Above 100V the transistor's collector-base acts as a zener diode and turns on the transistor which charges the capacitor over a short period. The current pulse turns off the transistor and the capacitor discharges slowly over the collector resistor until the collector-base voltage again reaches the breakdown level: they cycle then starts over again.

Title: Production of wool wax alcohols and acids - from wool grease
IPC: C11C1/02
Filed: 1970-07-31
Granted: 1972-03-10
Abstract: Wool grease is saponified with caustic alkali in a co-solvent mixture of isopropanol and water.
