Patent DE-3070761-D1 (DE)
Title: Electric heating radiator, and process and apparatus for its manufacture
Inventor: GOSSLER GERHARD
IPC: H05B3/20
Filed: 1980-12-09
Granted: 1985-07-18
Abstract: A method for the manufacture of a radiant electrical heater, intended more particularly for heating glass ceramic hotplates, comprises so inserting or pressing helical heating resistors in helical slots in a support, such that the support or the heater coils themselves are deformed and consequently fixed to the support. The coils penetrate the wall or bottom areas of the slot or are otherwise secured by parts of the support by positive engagement. An apparatus for performing the method has a tool with ribs which deforms the support or heater coils for positive engagement. A radiant heater is obtained, whose support has partly overlapping deformations in the slot area of the heater coils.

Title: Method for making bicomponent filaments; transition tube for use in making bicomponent filaments
Inventor: CRAIG JAMES PORTER
IPC: D01D5/32
Filed: 1981-02-23
Granted: 1985-10-17
Abstract: The method for making bicomponent filaments from two spin dopes wherein the dopes are assembled into alternating layers in a feed tube leading to a transition tube connected to a conventional spinnerette, the layers then being fed through the transition tube and the spinnerette to form filaments. The feed tube has a constant cross-sectional area along the length thereof and the transition tube has a parabolic configuration such that the linear flow rate of the assembled dope layers passing through the transition tube decreases at a uniform rate as the cross-sectional area of the stream of assembled layers is increased to the cross-sectional area of the spinnerette, to thereby maintain the distinctness of the interfaces of the layers and thus insure that good bicomponent filaments will be formed.

Title: Cables with extruded dielectric
Inventor: JONES MARTIN PHILIP
IPC: G02B6/04
Filed: 1983-02-19
Granted: 1986-06-19
Abstract: An optical fibre cable having a strength member has a dielectric sheath estruded over it. When a joint is to be made in the optical fibres or in the strength member which would necessarily result in a bulge in the cable at the point of the joint, this joint is nevertheless drawn through the extruder which has a variable extruder point to accommodate the bulge, whereby a jointed cable can pass through a continuous extrusion process without the need for stopping the extrusion process. Any reinstatement or making good of the dielectric sheath is done after the sheath has been extruded, at the point of the joint.

Title: Chemisorption apparatus
Inventor: DURAN MELCHOR
IPC: F24V30/00
Filed: 1984-04-06
Granted: 1987-07-30
Abstract: A chemisorption thermal system provides a cooling output by revolving an array of thermal elements through heat sink and heat source temperature zones defined within a cylindrical housing. Each thermal element is an enclosed elongated body having an absorbent material at one end and a reactant containing part at the other end. Reactant is desorbed from the absorbent material in one part of the thermal cycle, and then evaporated from the reactant containing part to provide a cooling output in another part of the cycle. It is particularly suitable as a vehicle air conditioner using the engine waste heat as a heat source and the vehicle radiator as a heat sink. The invention also makes use of dry chemical absorbent materials which have high heats of reaction allowing the system to have a high heat capacity and low volume. The thermal cycle may be reversed to provide a heating output.

Patent DE-3585689-D1 (DE)
Inventor: WARD JR
IPC: C12Q1/10
Filed: 1985-10-31
Granted: 1992-04-23
Abstract: Methods and associated devices for detecting the presence of a particular motile organism within a sample are disclosed. The sample may be derived from dry milk, raw meat, poultry or a clinical specimen. A preferred method includes inoculating a selective enrichment medium containing a chemotactic attractant with the sample and contacting the selective enrichment medium with a nonselective motility medium containing a chemotactic attractant in a concentration less than the attractant concentration in the selective enrichment medium. Upon incubation, the motile organism metabolizes the chemotactic attractant, allowing the organism to move into the motility medium where it interacts with antibodies specific for the organism, thereby causing the formation of a persistent immobilization band. The methods are particularly useful in detecting Salmonella.
