Title: Synchronisation supervising method and device in a time division multiplex system
Inventor: MULLER HORST DIPL ING
IPC: H04L1/00
Filed: 1983-12-16
Granted: 1986-08-28
Abstract: 1. A method of monitoring the synchronisation of a t.d.m. system and of initiating resynchronisation at a predetermined value of the frequency of non-conformity between an expected frame code word and the bit pattern actually occuring at this position, characterized in that at the transmitting end, during a determinate measuring period (M1, M3, M5... Mn), in a determinate time relationship to the frame code, it is determined whether the sum of all the transmitted bits of a logic state is even or odd, that a parity bit is formed, the logic status of which provides a statement as to whether evenness or oddness has been determined, that the parity bit is inserted into an unoccupied time slot of the pulse frame, that at the receiving end, during the same measuring period, in the same time relationship to the recognised but possibly incorrect frame code, it is determined whether the sum of all the received bits of the logic state which has been selected at the transmitting end is even or odd and that the receiving-end result is compared with the statement contained in the received parity bit.

Title: A sealing means for a door lacking a threshold
Inventor: EINARSSON STEFAN
IPC: E06B7/22
Filed: 1983-11-16
Granted: 1986-10-16
Abstract: A simple and efficient sealing means for a door lacking a threshold and which does not require any major recessing in the door leaf comprises a lath (11) of resilient material, which with a substantually plane main portion (15) is attached to the lower edge of door leaf (10). A head (16), enlarged with respect to the main portion, is provided with sealing ridges (19) and may be bent in relation to the attachment of the lath, so the ridges will be forced towards the floor. 
<??>An actuating member (29) comprising a longitudinally compressible leaf spring is fitted between the lower edge of the door leaf and the head (18) of the lath, so it extends outside the vertical hinge edge of the door leaf. Just before the door reaches its closed position the leaf spring contacts the door frame, and will then force the portion of the head adjacent to the hinge edge downwards. During the terminal portion of the closing movement the friction between the floor and the downwardly turned portions of the ridges will <<roll>> the head to full contact with the floor.

Inventor: PETERSSON STIG ARVID
IPC: C22B13/02
Filed: 1984-05-14
Granted: 1988-01-21
Abstract: The invention relates to a method for producing lead from sulphidic lead raw-materiais by direct smelting processes of the kind in which the lead raw-materials are smelted autogenously in a shaft with the aid of oxygen gas, or air enriched in oxygen, optionally by adding fluxes, there being formed an oxide-containing molten product which is caused to pass into a coke bed arranged in the lower part of the shaft, to form a lead phase and a slag depleted in lead. The invention is characterized by heating the coke bed continuously, by partially combusting carbon therein and/or by supplying electrical energy thereto.The electrical heating is preferably effected by supplying electrical energy through induction or through electrodes.When heating the coke bed by the partial combustion of coke in the bed, oxygen gas or air enriched in oxygen is preferably introduced directly into the coke bed, through tuyeres or lances.

Abstract: An electronic circuit measures the distance dependent variation of the inductance of a coil (1) whose core is displaced w.r.t. it. The electronic circuit contains a microcomputer (3) which stimulates the coil with a voltage step. It evaluates the displacement dependent inductance from the resulting charging current using a time measurement . The coil charging current is used to charge up a capacitor (7). The capacitor discharges across a resistor (8) with a time constant large compared to the charging time. The discharge time is evaluated by the microcomputer to produce the distance dependent parameter.

Abstract: To counteract the tendency of over-steering when a vehicle operates in a curved path, and one of the wheels-typically the wheel at the inner side of the curve exhibits a tendency to block and, then, braking pressure is reduced to one of the front wheels only, the braking pressure applied to the rear wheel or wheels is reduced. If braking pessure is reduced to both of the front wheels, braking pressure being applied to the rear wheels is controlled, independently, in accordance with anti-brake lock control considerations, which have priority over dropping of braking pressure to prevent over-steering.
