Patent EP-0043799-A1 (EP)
Inventor: HEIERLI WERNER
IPC: F24S23/70
Filed: 1981-06-29
Abstract: The solar collector possesses a heat exchanger (1) which, on its side facing the radiation area, is provided with a reflecting layer (12) for low-wave infrared radiation. The effect is to prevent losses arising as a result of reflection. In order to avoid losses caused by reflection and refraction, the reflecting layer is directly embedded into the material surface of the heat exchanger without a separating layer or is connected thereto. The absorbing layer (11) is embedded in the reflecting layer. Advantageously, the heat exchanger (1) consists of detachable, temperature-resistant plastic, in particular polyphenylene oxide. The reflecting layer advantageously consists of polycarbonate. The degree of absorption is further improved by a masking plate (5) with a reflecting layer (13) for the long-wave infrared range. The reflecting layers can simply be dissolved in a solvent and applied to the material surface. In this procedure, the solvent is selected to be such that both the material envisaged for the reflective layer and the material surface are dissolved or partially dissolved. <IMAGE>

Abstract: Un catheter a ballon (10) d'introduction dans un passage d'un corps comprend un ressort en spirale allonge (32) qui definit une ouverture. Ce ressort en spirale (32) est recouvert d'un enrobage de silicone qui comprend une gaine extensible (42), un collier d'elimination de contraintes (54) fixe sur la gaine, et une pointe de ballon (50, 52) fixee sur le collier d'elimination de contraintes (54). La gaine extensible (42) et une portion du ressort en spirale allongee (32) forment en combinaison une structure de support (30) qui s'allonge sensiblement lorsqu'une force d'etirement excessive est appliquee sur la structure de support (30) en tirant le ballon (50) au travers d'un passage d'un corps. Au fur et a mesure que cette structure de support s'allonge, le volume de l'orifice du ressort en spirale (32) augmente. De preference, le ballon (50) est en communication fluide avec l'orifice du ressort en spirale (32) de telle sorte que le volume du ballon (50) soit reduit lorsque la structure de support s'allonge. Le collier d'elimination de contraintes (54) est concu pour s'etendre en s'ecartant du ressort (32) pour recevoir du fluide provenant du ballon (50) pour reduire la pression du fluide dans le ballon (50) lorsque cette pression dans le ballon depasse une valeur predeterminee. Un mode prefere de realisation comprend une chambre flexible en forme de disque (24) en communication fluide avec le ballon (50), laquelle chambre est dimensionnee pour s'adapter entre le pouce et le doigt oppose d'un utilisateur.

Abstract: In a pump drive circuit, a power source voltage signal supplied to the pump (38) is phase-controlled by a triac (40) connected between the pump (38) and the power source (44). The period of triggering the triac (40) is determined by a time constant circuit of a UJT (66), a capacitor (74) and a resistor circuit (70, 78). The power source voltage signal has its frequency discriminated by a frequency discrimination circuit (4, 6, 8,10,12,14). The resistance value of the resistor circuit (70, 78) is determined in accordance with the result of the discrimination. Accordingly, the pump (38) is applied with a voltage signal phase-controlled in accordance with the power source frequency, and is thus driven at a predetermined value.

IPC: H01F1/153
Filed: 1982-03-05
Abstract: Amorphous alloys have attractive properties which make possible their use as cores for transformers, these properties being a low watt loss, which is due to an inherently low magnetic anisotropy, and a high resistivity. However, one of the most serious disadvantages of amorphous alloys is the low thermal stability of the magnetic properties and the fact that their magnetic properties, such as saturation flux density (Bs), decrease at the temperature of the energized or excited core. 
     In order to eliminate the disadvantages of the known amorphous alloys, the present invention proposes an amorphous alloy having a composition of Fe 74-80  Sis-19 B 6-13  C0 -3.5-  This alloy is specifically adapted so that it can be used as a transformer core which can be energized or excited at a high flux density.

Abstract: A variable speed transmission (1) for use for example in transmitting power from an electric motor drive (42) to a boiler feed pump (43), comprises mechanical gearing (2) including a slippage element, and a fluid drive system including at least one hydrostatic pump (13) driven by the slippage element and supplying power to an impulse turbine (Pelton 35) mounted integral on the transmission output shaft (6), but possibly as an alternative for constant torque operation on the input shaft (5). A spear valve (41) controls flow to the turbine. The gearing (2) is preferably a planetary gear and the slippage element can comprise the planet carrier (12) of the gear: the input (5) being via the annulus (7) and the output (6) through the sun (9) for step-up transmission or vice-versa for step-down transmission. For full output speed (100%) the pump (13) idles with no slippage and the drive is purely mechanical, but with increasing pump operation (spear valve open) and with increasing slippage the speed can fall to 70% full rate, but the turbine regains a substantial portion of the slippage power which is normally lost in conventional couplings as heat. A turbine by-pass (50) may be provided to permit lower speed operation. The above transmission (1) according to the present invention is efficient in operation, compact and of relatively simple construction, and is also economic to manufacture.
