Title: Plasmid vectors, plasmids containing genes for alkaline phosphatases and bacteria containing the latter, their preparation and use
Inventor: SIEWERT GERHARD DR
IPC: C12N9/18
Filed: 1980-07-28
Granted: 1988-02-25
Abstract: PhoA mutant E. coli SB44, prepared by mutation of E. coli HB101 with an N-nitroso compound, can be used to identify and isolate recombinant plasmids into which a phoA gene has been incorporated. These plasmids can be used to transform bacteria which can be cloned and incubated to provide alkaline phosphatase in high yield. Moreover, these plasmid vectors can be modified in various ways so that the N-terminal amino acid sequence of phoA is followed in reading phase by the DNA coding for some other protein. In turn, these new plasmids can be used to transform bacteria which can be cloned and incubated to produce fusion proteins comprising the desired other protein in high yield and outside of the cell membrane in the periplasmatic space.

Title: Press-fit electrical terminals
Inventor: VERHOEVEN LAURENTIUS MARIA
IPC: H01R43/00
Filed: 1983-03-01
Granted: 1986-02-20
Abstract: Press-fit electrical terminals such as press-fit pins for insertion into plated through holes of circuit boards. Such pins have a generally H-shaped press-fit zone formed by a central web 2 indented with a series of transverse corrugations 4 interconnecting four perpendicularly extending compliant fins 10, 11', 12, 12'. Preferably the terminals are formed by stamping from sheet material with plurality of such pins remaining interconnected to a carrier strip until after mass insertion into plated through holes. Stamping with a pair of corrugated-faced dies into opposed anvil members reduces longitudinal movement of material during swaging and improves dimensional tolerances. The corrugations on the central web reduce flexing of the pin after installation in the plated through hole. Preferably, the terminals include a slug of solder held on at least a portion of each of the opposed faces of the central web.

Patent DE-3376810-D1 (DE)
Title: Autoregulating electric heater
Inventor: KRUMME JOHN F
IPC: B23K3/04
Filed: 1983-11-25
Granted: 1988-07-07
Abstract: An autoregulating electrically shielded heater employs a structure of two magnetically permeable members of different Curie temperatures and preferably differing resistivities. The two members are in electrical contact with one another; having at their interface a very low resistivity layer or member provided by copper or a like material. A first of the electromagnetic members has the lower Curie temperature and high resistivity while the other of said members has the higher Curie temperature of the two and preferably lower resistivity. A constant current a.c. source is connected to induce currents in the members parallel to their interface. Below the Curie temperature of the first member, current is substantially confined to a narrow region along a surface remote from the interface. Above the Currie temperature, some of the current spreads into the low resistance layer or member and into the second electromagnetic member where it is confined, due to skin effect to a narrow region adjacent the interface. The 1<sup>2</sup>R heating is greatly reduced, 6 to 1 in a typical case, so that autoregulation of temperature occurs near the Curie temperature of the first member. Since the current in the second electromagnetic member is limited in its penetration by skin effect, a low frequency power supply may be employed in a thin device without radiation of the electromagnetic field.

Abstract: An air-cooled internal combustion engine having a series of in-line cylinders with a cooling air blower adjacent an end cylinder. The blower delivers a stream of cooling air in the longitudinal direction of the engine which is redirected by air guide means laterally across the cylinders.
