Abstract: System for measuring or monitoring the intracranial pressure which comprises a non-elastic detecting pouch to be inserted into the space between the skull and the cerebrum, a flexible tube connected to the pouch, a device for supplying a liquid into the pouch through the flexible tube and a device for measuring the pressure of the liquid in the pouch. When the pressure of the liquid reaches the intracranial pressure, the curve showing relation between liquid pressure vs. pouch volume flattens. Thus, by measuring the pressure of the flattened region, intracranial pressure may be determined.

Abstract: Coin sorting apparatus is described in which coins are taken from a hopper and positioned one by one into corresponding recesses in the outer periphery of a rotary disc. The disc rotates the coins in a circular arc. As it passes along its arcuate trajectory, each coin is sensed for its denomination so that a count can be made and recorded. The coins are fed over a series of openings of progressively increasing sizes so that each coin will fall into the first opening that can accommodate it. Each opening leads to a chute for directing coins into a corresponding collecting bag. Each bag thus collects only coins of one particular denomination and the number of coins therein are recorded.

Abstract: A diaphragm assembly for the demand regulator of a breathing apparatus utilizes a diaphragm that gradually flattens down against a conical platform so as to reduce the effective sensing area. Advantageously the diaphragm is used in conjunction with an aspirator opening adjusted for maximum aspiration effect at low flow rates. At increased flow rates the reduced sensing area compensates for increased aspiration, insuring stable operation. The diaphragm periphery cooperates with the conical platform outer edge to serve as the regulator exhaust valve.

Abstract: A weft thread carrier is disclosed for a loom with a weft thread supply at each side thereof and wherein the carrier, just before entering the shed, engages a weft thread segment that it draws into a loop while moving in the shed. Each weft thread segment extends across the carrier path obliquely to that path, from its supply through a fixed thread eye to the selvedge. The carrier has a hook projecting towards each of its ends, each capable of catching a weft thread segment, but it also has a deflecting surface for each hook, so arranged in relation to its hook that it deflects a thread segment away from the hook if the segment is at one oblique angle to the carrier path but permits the hook to engage a segment at the opposite oblique angle. Hence, as the carrier emerges from each side of the shed it merely deflects the thread segment across its path, but in moving towards the shed its then-forward hook engages the same segment.

Abstract: A compressed-air storage installation comprising a heat accumulator for storing heat contained in compressed air and the air is passed into subterranean caverns. The heat accumulator has partitions therein which are provided between a storage medium. The partitions form a number of air passages through which the hot compressed air entering at the central region of the heat accumulator flows in an essentially outward direction, thereby cools and flows on into the cavern.BACKGROUND OF THE INVENTIONThe present invention relates to a new and improved construction of a compressed-air storage installation having a heat accumulator for storing heat contained in compressed air, with the compressed air being passed into subterranean caverns.It is already known to employ compressed air instead of liquids as a storage medium for storing energy. The state-of-the-art compressed-air storage installations store compressed air at times of low load and utilize it at times of peak load to generate additional peak load energy.

Abstract: An automatic control system for regulating the temperature of the passenger compartment in automotive vehicles is disclosed of the type in which a vacuum operated actuator is utilized to control the position of a blend air door, the position of the blend air door in turn controlling the temperature of the air circulated into the passenger compartment by proportioning the flow of cooled air circulated through a heater prior to entering the passenger compartment. This air flow is utilized to correct the temperature level in the passenger compartment. The disclosed control system features a nulling pressure signal feedback loop in which the error signal developed by the difference in the temperature selector and sensor signals acts on a vacuum modulator to generate an actuator pressure level which is sensed and a corresponding electrical signal used to null the temperature error signal, to provide a stabilizing feedback loop in the control system.

Abstract: A selected number of heat pipes, located in the front rows of a plurality of otherwise operable heat pipes which are disposed between intake and exhaust ducts, have liquid-trap sections extending into a switching section. During normal operation, reservoirs in the switching section are dry and the plurality of heat pipes operate in a conventional manner. However, if some of the heat pipes in the exhaust dust become frosted over or otherwise too greatly cooled due to excessive cold in the intake duct, thermostatically or command-controlled valves or louvres cause the fluid stream in the exhaust duct to warm up or defrost the excessively cooled heat pipes therein. Prevention of excessive cooling is used to avoid frost build-up in air conditioning equipment, or solidification of solids and condensation of corrosive liquids.
