Abstract: A quick and simple immunoassay technique applicable to the determina­tion of large molecules like proteins, polynucleotides and others involves labelling competitive immuno-species with an enzyme as signal generator. This enzyme can be converted to the corresponding apo-enzyme form and its regeneration, upon addition of a suitable co-factor, is inhibited by com­plexation when the labelled specie is reacted with its immunopartner. The degree of complexation is therefore ascertained by measuring the extent of regenerated activity.

Title: Process for controlling the heating power of an ac cooker heating body and a control device for controlling the heating power of such a body.
Inventor: KELLER EDWIN
IPC: G05D23/19
Filed: 1987-01-30
Abstract: In order to be able to set the quasi-instantaneous heating power supplied to a heating element (1) of a cooker and hence to avoid the heating element having virtually full power applied to it in instantaneous operation and then being switched off from the power supply, it is proposed to drive a timer unit (21) whose output pulse widths (A21) are controllable from a control element (11) in order thus to drive a switch (19) to switch the power on, either in the sense of phase control of the AC voltage supplied from the mains (5) or in order to determine the lengths of the switched-on AC voltage and current packets in proportion to the switched-off time duration. <IMAGE>

Title: Injection of substances into high temperature liquids.
Inventor: BATES KENNETH WILLIAM
IPC: C22B/
Filed: 1987-02-18
Abstract: Gas injection into a metal melt, accompanied if desired by powdered or solid treatment substances, is by way of a nozzle (14) inserted into the wall (12) of a melt-containing vessel (10). The nozzle bore (18) initially has a stopper (20) at its inner end and a delivery pipe (24) smaller than the bore (18) is movable therein. Before injection, the pipe (24) and bore (18) adjacent the stopper (20) are cooled by gas. By thrusting the pipe (24) against the stopper (20) while sufficient gas flow and pressure is maintained, the stopper is dislodged and the gas will enter the melt as a jet which leaves the pipe (24) at a velocity equalling or exceeding Mach 0.5. Melt enters the clearance between the pipe (24) and bore (18) but, due to the pre-injection cooling, rapidly freezes locking the pipe safely in the bore.

Abstract: A structure of an engine using a cylinder block having a cross-section forming a predetermined curved surface, and a piston having a curved surface identical with the curved surface of the cylinder block, in which engine the arcuate reciprocating movements of the piston along the curved surface can be transmitted as a shaft-driving rotational movement. With the hybrid rotor engine thus constructed, in which the arcuate reciprocating movements of the specially formed cylinder block and piston are transmitted to a connecting rod body consisting of a connecting rod, a rotor journal and a rotor gear, the shaft-driving force can be efficiently transmitted.

Patent EP-0310197-A1 (EP)
Inventor: PEDERSEN HANS NORGAARD
IPC: F16L51/00
Filed: 1988-09-30
Abstract: In subterranean district heating pipe systems the problem occurs that the end portions of long, straight pipe stretches (2) expand and contract by temperature changes of the conductor pipe (16) of the heat insulated pipe, this giving rise to corresponding lateral displacements of the end portions of the transverse pipe elements (5, 6) as joined with the ends of the long pipe stretches (2). Such dis­placements are in no way desirable, and they can be counter­acted by expensive ground anchorings. According to the in­vention they are not eliminated, but reduced to an accept­able level in a simple and cheap manner, viz. by using for the said end portions such pipe elements (3), the outer sur­face of which is provided with a coarse pattern of marked depressions (10, 20), which serve to increase the friction between the pipe and the surrounding infill material (18) when the latter is of a high internal shear strength. Hereby the said displacements are reduced considerably.

Abstract: A fueling nozzle (10) for pressurized fuel systems having a body (12) connectable to a tank inlet. The body includes an axially displaceable valve (112) movable between a closed retracted position and an extended open position. Connection of the body to the tank inlet occurs upon rotation of the connection sleeve (68) and positioning of the valve is achieved by a rotatable cam sleeve (36) having a cam slot (46) in which a valve-mounted follower (142) is located. An interlock (82) senses mounting of the body on the tank inlet permitting rotation of the connection sleeve in a locking direction and upon the connection sleeve being fully rotated to a locked condition a second interlock (98) permits rotation of the cam sleeve and valve movement from the closed to the open position. The nozzle is characterized by reduced flow resistance characteristics and safe operation.

IPC: G06F15/16
Filed: 1988-12-23
Abstract: In a shared memory system, wherein several memory users MU(11) accede to a plurality of memory banks (17), a set of high level commands (CREATE, PUT, GET, RELEASE, ENQUEUE, DEQUEUE) is provided, to transfer data between a given memory user and the memory banks or another memory user. The high level commands sent by the memory users are built up by memory interfaces MI(13) connected to said memory users, and transmitted through an interconnection network (15) to Packet Memory Command Executors PMCE(12) integrated into each memory bank (17). The high level commands work with data records identified by Logical Record Addresses (LRA) known by the memory users. During execution of the high level commands by the PMCE (12), said LRA are translated into physical addresses corre­sponding to physical address space in the memory banks. Said physical address space dynamically is created and released upon need, through the Create or Release Com­mands. 
     A given memory user is not involved at all by management of physical address space, and works only with the LRA of a record.
