Title: Method and circuit arrangement for the transmission of data signals between control devices connected to one another via a loop system
Inventor: MICHELS-KROHN KARL-HEINZ
IPC: H04L12/433
Filed: 1986-09-10
Abstract: A data transmission system has a number of control devices connected via a transmission loop. Each control device includes signal processing circuitry which compiles data signals to be transmitted in the form of a data signal block. The signal processing circuitry is followed by a transmit buffer, which includes a write/read memory. A prepared data signal block can be accepted into this memory. A counter is connected to the memory which continuously addresses the memory for accepting a data signal block, and for emission thereof to the loop upon the appearance of a transmit authorization signal. The write/read memory is followed by a register. In addition to memory locations for accepting a data signal word, this register additionally includes memory locations for auxiliary information to be attached to the individual data signal words. The auxiliary information is derived from counter readings of the counter.

Title: Reversible immobilization of assay reagents in a multizone test device
Inventor: WOODRUM DAVID L
IPC: G01N33/52
Filed: 1987-03-19
Abstract: A multizone test device for the determination of analyte in a liquid test medium. The test device preferably comprises multilayers including a first layer comprising a solid, porous matrix incorporated with a reversibly immobilized first reagent and a second layer comprising a solid, porous matrix incorporated with a second reagent which interacts with the first reagent and analyte from the liquid test medium to provide a detectable signal. A reversible binding interaction between the first reagent and the matrix of the first layer prevents the first reagent from prematurely migrating into the second layer during manufacture of the device and prior to application of the liquid test medium to the test device. The reversible binding interaction is sufficiently disruptable by contact of the first layer with the liquid test medium to release and thereby render diffusible an analytically effective amount of the first reagent within the test device.
Patent ZA-873013-B (ZA)
Title: Solid-state instantaneous trip device for a current limiting circuit breaker
Inventor: LINDEPERG FRANCOIS
IPC: H02H3/44
Filed: 1987-04-28
Abstract: An instantaneous solid-state trip device has two threshold values providing an upper and a lower tripping threshold. A current increase rate detector determines, when a short-circuit occurs, the prospective peak current value and, if the peak value corresponding to the electrodynamic withstand of the circuit breaker is liable to be exceeded, causes a change of threshold to bring about tripping, as soon as the lower threshold is exceeded. This high-speed tripping favours short-circuit current limiting. When a short-circuit of a lesser importance occurs, the current variation is lower and the instantaneous trip release only trips when the upper threshold is exceeded. In most cases, this upper threshold is not reached and tripping selectivity can be easily achieved in the usual way. A break in the circuit connecting the sensor to the trip unit also causes the circuit breaker to trip.

Title: A method of extending rolls of dough and compression plate for use in said method
IPC: A21D8/02
Filed: 1987-05-15
Abstract: A method and apparatus are disclosed for moulding pieces of dough into long thin cylinders. To avoid an irregular shape of the final product and/or a non-uniform interior dough structure, the pieces of dough are rolled over a working surface while pressure is exerted on each half thereof, distributed over a plurality of adjoining transverse zones, by elements of the working surface. Each of the elements is laterally movable substantially in proportion to the local dough migration. For this purpose the invention provides a compression bed for use in an extender over a movable carrier. The side of the compression bed which faces the carrier is constituted by elements symmetrically arranged relatively to the longitudinal median plane of the compression bed and journalled for lateral movement.

Title: Process for melting scrap iron,sponge iron and/or solid pig iron or the like
Inventor: BOGDANDY LUDWIG VON
IPC: C21C5/56
Filed: 1988-08-08
Abstract: For melting scrap, iron sponge pellets in the reduced form, solid pig iron or the like, it is proposed to supply the melting heat by means of burners from below and, without additions of coal to the charge, to set a corresponding carbon content in the molten bath by less than stoichiometric combustion of hydrocarbons. At the same time, the aggressivity of the slag is diminished by reducing the oxygen flow, especially by combustion with approximately 0.9 times the stoichiometric quantity of oxygen, and, if appropriate, an addition of slag formers.

Filed: 1989-03-29
Abstract: A curd and whey mixture is drained of loose whey on a conveyor and the dry curd fed into the top of a tubular perforated column (4) maintained under sub-atmospheric pressure to form a pillar of curd. A mass of curd severed from the lower end of the pillar is deposited in a mould (14) mounted on a turntable (13) rotatable to index the mould in succession at six pressing stations at each of which the curd is compressed for 45-120 seconds at a pressure of at least 4 bar in order to form a block of cheese with a rind firm enough to permit handling of the cheese block after ejection from the mould. At the first pressing station the curd is subjected to a sub-atmospheric pressure of -0.9 to -1.0 bar prior to compression. After the cheese block is ejected from the mould, the turntable returns the empty mould to the column for reception of another mass of curd.
