Filed: 1981-04-08
Abstract: A closed loop path through which a working fluid is circulated includes a prime mover, such as a turbine (16), to which operating fluid in the vapor state is supplied from an evaporation chamber (10) which is partially filled with operating liquid. A condenser (14) is located adjacent the bottom of the chamber (10). Working vapor discharged from the turbine (16) is passed through the condenser (14), the heat of vaporization passing from the vapor into the operating liquid within the chamber. From the condenser (14) liquid is pumped through heating means, such as a solar collector (26), for heating the liquid without vaporizing the same and the heated liquid is passed into the evaporation chamber (10) for vaporization. Heat absorbed by the evaporating operating liquid cools the liquid in the evaporation chamber. The cold operating liquid at the bottom of the chamber (10) facilitates removal of heat from the turbine exhaust. <IMAGE>

Title: Method of controlling a vehicle ventilating air flow
IPC: B60H1/00
Filed: 1981-08-17
Abstract: In a method of controlling the quantity of air for ventilating or air conditioning the passenger compartment of a vehicle, i) the flow of air in a channel subject to dynamic air pressure is controlled by altering, by means of flaps (7, 8, 9) the air flow cross-section, and ii) the air flow rate in the channel is controlled by altering the speed of rotation of a fan (12). In dependence on vehicle speed, the air flow cross-section is altered in at least two steps and the fan rotation speed is infinitely varied, the rotation speed also jumping from one value to another when the air flow cross-section is abruptly changed. The flap adjustment drives (4, 5, 6) and the fan motor (11) are controlled by electronic control means (1, 10) which can be regulated from a tachometer (2) and a setting device (3). The arrangement is such that the variation of air flow cross-section as a function of vehicle speed follows a stepwise path, while the variation of the fan rotation speed as a function of vehicle speed follows a saw-tooth path. <IMAGE>

Title: Method of making fiber reinforced articles
IPC: B29C39/00
Filed: 1981-09-24
Abstract: An improved method is disclosed for forming articles, especially airfoils, comprised of a fiber reinforced plastic bonded to a metal object. In the manufacture of a propeller blade a subassembly is made by coating a metal spar with a certain class of adhesive to a depth of 127-1016 microns to compensate for dimensional variations in the spar surface, transferably coating the interior of a subassembly mold with the adhesive, then inserting the coated spar into the mold and injecting a lightweight filler material. The adhesive and filler are then precured and the subassembly removed from the mold. A fibrous reinforcing material, such as glass fiber cloth, is then used to cover or wrap the subassembly, the subassembly thus covered is placed in a second mold, and a synthetic polymeric material such as epoxy resin, previously or subsequently applied, is then cured. In the formation of other articles, the filler material might be entirely omitted, and the reinforcing fibers would be separated from a metal substrate only by the precured adhesive.

Patent GB-2098038-A (GB)
Title: Dual mode colour switch for beam penetration CRT
IPC: H04N9/27
Filed: 1982-04-22
Abstract: A colour switch for a penetron CRT changes the voltage of anode (24) fed from variable supply (10) via transformer secondary (14), thus changing the colour displayed. A feedback circuit (50, 52) detects the direct component of voltage across the primary and biases driver (34) to zeroize this component. Two modes of operation are available: the first applies to a regular sequence of colour-write periods in different colours; to avoid colour variation with change of duration of individual periods, switch (66) is open and (30) closed so that the input signal to the driver (34) also alters the reference level of HV supply (10), eliminating the effect of duty cycle. In the second mode, switch (66) is open, and a reset period is allowed after a colour-write period for magnetizing current to normalize. At the beginning of each reset period switch (30) is opened so that energy is returned to the LV supply via one of diodes (42, 44) to accelerate recovery. Dynamic focus is provided by winding (72), applying a selected fraction of the anode voltage to electrode (76). <IMAGE>

Title: Vector KVA meter
Inventor: BERGERON JEAN-MARIE
IPC: G01R21/00
Filed: 1982-12-14
Abstract: A meter apparatus for determining Vector VA demand, and other electrical quantities, over a predetermined time period, uses a watthour meter and a Q-hour meter with pulse initiators. The time period is divided into a plurality of sub- intervals and the VAh or other quantity is determined for each sub- interval  DELTA t. Thus DELTA VAh is determined using the relationship   <IMAGE> where  DELTA Wh is the output from the watthour meter and  DELTA VARh is a value for  DELTA VAR hours determined generally from the relationship   <IMAGE> where Qh represents Q-hours and  phi  represents an angle by which the voltage vectors are rotated for measurement by a Q meter of Q- hours.The values of  DELTA VAh for the sub- intervals in the time period are summed to provide total VAh for the time period, and from which can be calculated the Vector VA demand for the time period. By making the determination based on relatively short subintervals, the inaccuracies introduced by changing power factor over the time period are reduced or eliminated for all practical purposes. <IMAGE>
