Filed: 1990-05-03
Abstract: A b s t r a c t The invention describes a gas-tight fully protective suit  (2) which is worn in a polluted environment and protects the wearer against toxic substances.  If combustible or explosive mixtures of gases and vapors are present in the surrounding air and are within the lower explosion  limit and  therefore  constitute a risk of explosion,  the wearer must be warned by being informed of the fact.  To this end according to the invention, a measuring and alarm instrument (1) is disposed under the suit and comprises a diffusion measuring head (3) having active and inactive gas-detecting components. The diffusion-measuring head (3) is disposed in a gas-tight easing (5) in the suit material  (2a), the easing being separated from the outer atmosphere by a diaphragm (12).  The diffusion-measuring head (3) is connected by a cable  (4) to the indicating and alarm instrument (1), which is secured to the wearer's body (Fig. 1).

Abstract: A cooling liquid is injected into and supplied to a cooling tubular body along its inner periphery to form a cooling liquid layer flowing down the inner peripheral surface of the body while revolving.  A molten metal is then injected into the cooling liquid layer from the inner peripheral side thereof to divide, rapidly cool and solidify the stream of molten metal with the cooling liquid layer and obtain a metal powder.          Since the metal powder is continuously obtained upon flowing down the tubular body along with the cooling liquid, the liquid can be continuously removed from the powder by suitable means, and the power can be subsequently dried continuously.

Abstract: An electromagnetic clutch assembly for use with a refrigerant compressor for an automotive air-conditioning system includes a first rotatable member, such as a rotor, having an axial end plate of mag-netic material and a second rotatable member connected to an outer end of a drive shaft of the compressor. An armature plate of mag-netic material is elastically connected to the second rotatable mem-ber. The armature plate faces the axial end plate of the rotor with an axial air gap therebetween. An electromagnetic device is disposed within the rotor and is operable to attract the armature plate into contact with the axial end surface of the rotor such that the rotation of the rotor can be transmitted to the drive shaft when the electro-magnetic device is activated. The electromagnetic device includes at least first and second electromagnetic coils which are axially aligned so as to generate a thermal difference therebetween when heat is conducted to the electromagnetic device from a contact surface between the axial end plate of the rotor and the armature plate. The first and second coils are connected in series between the battery and ground. A control device controls the connection and disconnection of the electromagnetic device to the battery. The control device disconnects the electromagnetic device to the battery when the ther-mal difference exceeds a predetermined value while the electromag-netic device is activated.

Patent CA-2041948-A1 (CA)
Inventor: ERIKSSON HAKEN O
IPC: H04B7/06
Filed: 1991-05-07
Abstract: The invention relates to a method for transmitting, in a time-multiplex radio communication system, for instance a GSM-type (Global System For Mobile Communication) mobile telephony system, different commands from a movable station to a fixed station with respect to the selection of transmitter antenna in the fixed station. Each transmission sequence from the movable station includes a synchronizing word which consists of a predetermined number of binary bits. The different commands are transmitted by using different synchronizing words in dependence on the command to be transmitted. The movable station has access to at least two different synchronizing words. The synchronizing words used in addition to a standard synchronizing word are formed by the binary bits from the standard synchronizing word being shifted laterally to mutually different extents and/or in mutually different directions in order to generate different, new synchronizing words. In this way, there is formed in the receiver of the fixed station an impulse response having a pulse which occurs at different time points depending on which synchronizing word was used by the movable station.
