Title: Process for bit-oriented data transmission.
Inventor: OPPER BURKHARD
IPC: H04L1/00
Filed: 1990-11-20
Abstract: The invention concerns a process for bit-oriented data transmission using a high-level data-link control (HDLC) protocol. To increase the Hamming distance to the flag of the HDLC protocol, it is proposed that, at the transmission end, before the HDLC controller, two consecutive bits in the data field are each converted into a tuple codeword comprising more than two bits, one codeword having 0 bits and the three others only one 1-bit each. At the receiver end, after the HDLC controller, the codewords are converted back into two consecutive data-field bits. Using tuple and quadruple codewords, a Hamming distance of d = 3 and 4, respectively, can be obtained.

Abstract: A method for the inhibition of scale deposition on thesurfaces of a well coproducing oil and scale forming brines comprising injecting into the well reservoir an acidic (aqueous) solution at a first pH containing dissolved therein a scale inhibitor, multivalent metal ions, and a heat sensitive pH increasing substance which decomposes at elevated temperatures liberating an alkaline compound such that the solution is inherently heated by the higher ambient reservoir temperature to a temperature at which the alkaline compound is liberated from the heat sensitive substance thus raising the pH of the solution to a point at which a sparingly soluble multivalent metal salt of the scale inhibitor is phase separated from the solution on the porous surfaces of the reservoir rock formation, providing for a slow release of inhibitor into the produced brines when the well is in its production phase.

Abstract: A network-field interface, termed an NFI (12) is intended for digitally interfacing at least one host computer (14) on a network (10) to at least one field device (11). The network (10) operates with a predetermined communications protocol including READ and WRITE services. The NFI comprises I/O ports (22,24) for connection to the field devices, a modem (55,Fig.5) to facilitate communication between the network and the interface, a CPU (51,Fig.5), volatile and non-volatile memory (52,53,Fig.5) accessible to both the modem and the CPU, and program modules resident in the memory. The program modules are executable by the CPU to map the READ and WRITE services of the network onto the NFI's I/O ports. In this way the host computer is able to READ and WRITE directly to the I/O ports through the modem.

Abstract: An electrical storage heater comprises a heat store, electrical means for heating the heat store, an internal air passage extending through the heat store and a damper for controlling the convective flow of air through the internal passage and out of ventilation apertures (12b). 
     To provide a controllable heat output, the user can adjust a knob (17) to vary the tilting of an arm 15 for tilting the damper (13) to either cover or uncover the apertures (12b). The tilting of the arm is also affected by a bulb sensor sensing temperature fluctuations in the room. 
     A bimetallic strip (16) is provided to assist in damper closing at the start of an off-peak period, but in accordance with the invention it is secured to the damper itself rather than to the actuating arm (15), and so benefits from heat reception by conduction from the damper instead of simply convection as hitherto. This enables an off-peak operated pilot heater for the room temperature sensor to be deleted.

Abstract: The subject of the invention is a machine for reprofiling worn rails (1) in which the rail can move opposite one or more stationary shaped milling cutters (10) (10a) which reprofile, in a single pass, the useful part of the rolling surface and the blend radius of the latter with the lateral flank of the rail head. The rail is guided in its advancement in the milling zone on the one hand by fixed rollers (3) bearing on the face to be machined and, on the other hand, by groups of oblique movable rollers (4) arranged to support and laterally bear against the rail head. The oblique movable rollers are mounted on the clevises (5) which tilt together symmetrically and transversely to the rail about 2 shafts (6) parallel to the rail and on each side of the latter. The shafts (6) are integral with supports (8) actuated by means of thrust cylinders (9). Under the effect of the thrust cylinders (9) the oblique rollers become placed bracing the rail (1) bearing on each side of the latter on the shafts (6). The groups of movable rollers are located respectively in the upstream and downstream vicinity of the milling cutters (10), (10a) according to the direction F1 of travel of the rail (1) and successively and temporarily move away under the advancing thrust of the rail when passing by a welding increase in thickness (1a), whilst the level of the machining pass line determined by the fixed rollers (3) remains unchanged, and the rail still remains guided. The structure of the support (8) which is largely open under the milling cutters, makes it possible easily to remove the machining chips. This particularly rigid guide device provides vibrationless machining and without the rail bending under the effect of milling. <IMAGE>
