Abstract: A helmet, including a cap body (1) comprising a shell (10) and a shock absorbing liner (11) fitted to an inner surface of the shell (10), and a longitudinally extending air duct (6) which is provided in a wall of the cap body (1), such that the inside of the cap body (1) can be ventilated through the air duct (6), wherein at least a portion of the shock absorbing liner (11) is divided into an outer layer (14₂) on the side of the shell (10), and an inner layer (14₁) superposed on an inner surface of the outer layer (14₂), the inner and outer layers (14₁, 14₂) having grooves (17, 18) provided in opposed surfaces thereof to define the air duct (6), the inner layer (14₁) having a vent hole (19). Thus, air flowing into the air duct (6) can flow at a high rate without any leakage, thereby reliably ventilating the inside of the cap body (1).

IPC: G21C3/322
Filed: 1993-03-22
Abstract: A water rod (W) is disclosed in combination with a fuel bundle (B) for a boiling water nuclear reactor in which water is introduced to the water rod (W) directly from the high pressure lower plenum (12) below the reactor core (40). This introduced water circulates upwardly and centrally through the water rod (W) to the top (16) of the water rod (W). Thereafter, the water flows peripherally downward adjacent the exterior (18) of the water rod (W). The introduction of water to the water rod (W) directly from the high pressure water plenum (12) below the reactor core (40) provides sufficient pressure to maintain water flow through the water rod (W) and to prevent flashing of the water passing through the circuitous path of the water rod to steam. Thereafter, the water is discharged at the bottom of the fuel bundle (B) with water entering the steam generation path through the lower tie plate (L) so that the discharged water participates in the steam generating flow path within the fuel bundle (B). Shunting of the water flow with the accompanying thermal hydraulic inefficiencies is avoided.

Abstract: A biasing device for actively biasing the base of an RF device (12) operating in quasi-linear modes. The biasing device provides a source of low-impedance current and high current capability. The biasing device includes three transistors (20,22,24), each having a base, collector and emitter and one low turn-on diode (26). The first and second transistors are connected such that changes in the base-emitter voltage of the biased RF device can be detected. The third transistor is configured in a Darlington configuration with the first transistor in order to provide (1) increased sensitivity to voltage changes detected by the second transistor and (2) additional collector voltage for the second transistor to prevent it from operating in saturation. The low turn-on diode is a compensating diode which thermally tracks and compensates for operating changes in the second transistor due to temperature.

Abstract: The automatic welder has a pressing and advancing device with two pressing rolls (20, 21) which are arranged one behind the other, are driven jointly and are looped around by a circulating pressing belt (22). The leading roll (21), in the travel direction, is mounted such that it can lift itself when it travels over unevennesses, thereby maintaining straight-line running. To improve said automatic welder even further, the two travel rolls (37) running in advance are arranged offset laterally and are mounted on a pivot plate (43) by means of which the travel track can be adjusted. Furthermore, the shaft (38) of the two travel rolls is not driven directly but a slip clutch in the form of two rubber blocks (39) is arranged between the shaft (38) and a separate drive shaft (18). The latter, and also the two pressing rolls (20, 21) are driven synchronously by a motor (10) by means of a toothed belt (13). <IMAGE>

Abstract: The ordered column packing for mass transfer between a falling film (trickling film) (14) and a gas has alternately arranged layers (10, 20). The one set of layers (10) guide the falling film against a vertical edge (13) of the layers, while the other layers (20) guide the falling film away from the edge. According to the invention, the layers are each coupled in pairs via return elements (3), with these return elements representing a liquid-carrying bridge: liquid (15) running along the edge of one layer (10) is thereby at least partially transferable to the associated adjacent layer (neighbouring layer) (20). <IMAGE>

Abstract: The present invention is concerned with a receiver device for converting electrical signal from a headphone, a telephone receiver or the like into acoustic signals and outputting these acoustic signals. More particularly, it relates to a noise reducing receive device in which acoustic signals in the vicinity of an electro-acoustic transducer element are converted by a microphone into electrical signals and negatively fed back to an amplifier circuit which is adapted for amplifying input electrical signals and supplying the amplified signals to the electro-acoustic transducer element. With the present noise reducing receiver device, the input electrical signals are amplified by the amplifier circuit and converted by the electro-acoustic transducer element into acoustic signals, which are output as output acoustic signals. A microphone, consisting of a pair of microphone units (16A,16B) having their diaphragms (16a,16b) disposed in proximity and in opposition to each other, is arranged in the vicinity of the electro-acoustic transducer element and adapted for converting the output acoustic signals and external noises into electrical signals, which are negatively fed back to the amplifier circuit via feedback circuit. The output acoustic signals may be heard at the desired noise reduction level by having the transfer function H of the electro-acoustic transducer element, the transfer function A of the amplifier circuit, the transfer function M of the microphone and the transfer function β of the feedback circuit presettable within the range of |AHMβ|»1.
