Abstract: ABSTRACT OF THE TECHNICAL CONTENT OF THE INVENTION          TITLE :     Servo-motor for power-assisted braking.            APPLICANT : SOCIETE ANONYME D.B.A.            INVENTORS : Pierre PRESSACO and Jean-Jacques CARRE.    TEXT :    The two chambers (8, 9) on either side of the movable wall structure forming a piston (7) are each sealingly delimited internally by a first and a second flexible impervious walls (23) which connect the central hub part (11) incorporating the control valve (12) to the central annular end zones (22 ; 24) of the corresponding end walls (2 ; 3) of the housing, the cen-tral zones delimited peripherally by said flexible walls being interconnected by at least a passage (39) traversing the cen-tral hub part, thus providing in the centre of the housing a neutral cylindrical zone (32). In this neutral zone (32) there extend force-transmitting elements (38) which have at their ends fastening means (40), for example with assembly flanges (41, 42), and which slidingly pass through said passages (39) formed in the body of the central hub part (11), thus in no way interfering with the control and fluid actuation system of the servo-motor.

The method comprises the steps of:  providing a bath of molten metal, forming the  melt in a continuous casting mold overlain by the fluid medium;  periodically thrusting a probe through the boundary layer toward the melt without contacting same and retracting the probe away from the melt so that the probe lies in the gas phase out of any cover of the  melt;  during the periodic advance and retraction of the probe measuring the electrical impedance between the melt and the probe to provide a control signal;  and controlling the level of the melt in the mold in response to the control signal, reversing the direction of movement of the probe in a vertical sense when a selected value of the impedance has been reached. And an apparatus for carrying out the method.

Abstract: ABSTRACT:           A multiple-access communications system for an unlimited user population is disclosed wherein a system controller continuously transmits Aloha signals on a slot-by-slot basis giving an updated number of time slots available whereby a calling party can select any one of the designated time slots at random.  The calling party checks the time slot immediately preceding its selected time slot to ascertain if the current Aloha number is zero (or an equivalent thereof).  If it is zero then the calling party reverts to listening for a time slot con-taining an Aloha number greater than zero.  Alternatively if it is not zero the calling apparatus sends a signal to the system controller in its selected time slot.  Multi-purpose signalling in each time slot can be carried out by the system controller thereby reducing the overhead on the system and speeding-up the setting-up of calls which may be off-air or non off-air.

Abstract: APPARATUS FOR BENDING GLASS SHEETS                    ABSTRACT An apparatus disclosed for use in bending heated  sheets  of  glass  transported generally horizontally  on  a  conveyor  within  a  furnace heating chamber includes a holder and a counter-balanced bending member, both of which are located above the conveyor in a spaced relationship such that a heated sheet of glass can be transported under the holder.  The holder includes a curved, downwardly facing surface with spaced openings in which vacuum is drawn to receive the glass sheet from the conveyor.   Gas,  such as air,  is blown upwardly  from  below  the  conveyor  against  the heated sheet of glass such that the sheet is moved upwardly  and  into  engagement  with  the  curved surface of the holder.  The bending member then moves  downwardly  below  the  holder  surface  and thereafter upwardly against the heated sheet of glass to provide bending thereof to the curved shape of the holder surface.  The bending member then moves back to its home position above the holder surface.  A carrier mold ring moves under the supported glass and the vacuum is then ter-minated so the glass drops onto the ring and bends under the bias of gravity in a manner that allows the glass to be further bent.  Subsequently, the mold ring is moved from the furnace to a quench unit that tempers the glass.

Abstract: ABSTRACT OF THE DISCLOSURE               A heat- generating member is arranged in a water-filled pressure vessel which is provided with a pressure relief valve or the like.  The water of the pressure vessel can be partly evaporated, thereby acting as a heat sink for the generated heat.  The walls of an outer vessel surround at least a lower part of the pressure vessel in such a way that a closed, relatively small auxiliary space is formed between the two vessels.  The auxiliary space communicates via at least one tube with an open evaporation pool, which is arranged above the cover of the pressure vessel.  A tube coil, disposed in an upper part of the pressure vessel, is connected by both ends to the evaporation pool.  If a leak should occur in the lower part of the pressure vessel, water from the auxiliary space flows to the evaporation pool via the tube and from the evaporation pool into the tube coil, whereby boiling takes place in the evaporation pool due to the high-temperature steam condensing on the tube coil.  The leakege, thus, does not result in a loss of the heat sink.
