Patent CA-2024169-A1 (CA)
IPC: B60M1/13
Filed: 1990-08-28
Abstract: ABSTRACT     First, a steel wire is continuously dipping in molten copper or molten copper alloy so that copper or copper alloy builds up and solidifies on the peripheral surface of said steel wire, thereby obtaining an initial copper-clad steel wire.  Then, the initial copper-clad steel wire is subjected a first cycle of hot rolling by a caliber roll.  The hot-rolled wire is dipped in molten copper or molten copper-alloy at least once so that copper or copper alloy builds up and solidifies thereon, thereby obtaining a final copper-clad steel wire.    The final copper-clad steel wire is hot-rolled at a temperature of 750 to 850°C and with a rolling ratio of 10 to 40%.  Then, the hot-rolled wire is cold-rolled with a reduction of area of 20% or more.  Thus, 75 to 90% of the cross sectional area of the obtained copper-clad steel trolley wire is occupied by the copper or copper alloy covering layer so that the electric conductivity of the trolley wire is very high as 80% IACS or more.  Moreover, the cast rod is hot-rolled so that the core and the covering layer are metallurgically bonded to each other, thereby obtaining a copper-clad steel trolley wire whose core and covering layer are firmly bonded.  Also, the hot-rolled wire is cold- rolled so that the trolley wire with a high strength is obtained.

Title: Control system and method for compensation for speed effect in a tandem cold mill
Inventor: PETERSON ROBERT S
IPC: B21B37/00
Filed: 1990-11-28
Abstract: A CONTROL SYSTEM AND METHOD FOR COMPENSATING FOR SPEED              EFFECT IN A TANDEM COLD MILL             ABSTRACT OF THE DISCLOSURE In an arrangement for a tandem cold mill in order to compensate for "speed effect," each stand has a roll force memory unit and an oil film roll force controller unit which operate together, and in conjunction with a tensiometer, to maintain a relatively constant roll gap during the acceleration and deceleration phases of the mill. In threading, in tailing out, and in a full run speed of the mill, the roll force memory unit is constantly operating to obtain a "lock on" roll force reference for the stand prior to the acceleration or deceleration phase.  A roll force error signal, which is the difference between a roll force reference of the roll force memory unit and an instantaneous roll force, enters the oil film roll controller.  A proportional integrator type controller in the oil film roll force controller unit changes the roll force error signal within a limit of + 25% of the desired tension.  This oil film roll controller produces a tension reference signal which is compared to the desired tension and selectively with the actual tension to produce a tension error signal used to control the roll gap control system of the stand or used to provide a speed change reference for the downstream stand.

Title: Color code system for use with sheathed cable fish stringers
Inventor: REYNOLDS DAVID W
IPC: A01K65/00
Filed: 1991-05-29
Abstract: ABSTRACT OF THE DISCLOSURE     This  invention  relates  to an improved sheathed cable-type fish   stringer   including   an    elongated, flexible, sheathed cable-type   stringer   which   is  devoid  of  the  conventional intermediate snap  hook  assembly  storage  loop.  The  invention further includes a remotely positionable or locateable caddy clip adapted  to be attached to one of the fisherman's person, attire, or  equipment.  When  fishing, a  plurality  of   different   and distinct  fishermen often use only one, single, remotely located, sheathed cable-type fish stringer, and a difficulty often  arises at  the end of the fishing trip as to who caught which fish.  The present invention color codes each fisherman's remote caddy  clip with  a unique different and distinct color.  Each fisherman then has attached to his particular caddy clip, a  set  of  snap  hook assemblies  wherein each of the slide units of each of the set of snap hook assemblies also includes  one  different  and  distinct color  which  uniquely matches the color of only his remote caddy clip.  Thus, when the day's fishing is done, each  fisherman  can positively  identify  those fish caught by him simply by matching the color of the slide unit on the snap hook  assemblies  on  the stringer  with  the  unique  color of his particular remote caddy clip so that no misunderstandings can occur.

Filed: 1991-06-20
Abstract: ABSTRACT  ELECTRONIC TRIP DEVICE COMPRISING AN IMPROVED LONG DELAY FUNCTION    To perform the long delay function of an electronic trip device, a quantity (TLR1) representative of the thermal current state varies proportionally to the difference (I2 - Is2) between the square of a value (I) representative of the current flowing, in a conductor to be protected and the square of a current threshold (Is). This first quantity (TLR1) is used in combination with a second value (TLRZ) to produce a tripping signal when the second value exceeds a preset value (TLR2max). The second quantity preferably increases proportionally to the square (I2) of the value representative of the current, when the first quantity exceeds a preset threshold (STLR1)  and decreases, preferably exponentially,  when the first quantity is lower than this threshold.    Refer to figure 7.

Title: Production of active pseudomonas glumae lipase in homologous or heterologous hosts
Inventor: BOS JANNETJE W
IPC: C12R1/40
Filed: 1991-07-04
Abstract: T 7013 (R) ABSTRACT          The production of an active Pseudomonas glumae lipase isolated from P. glumae PGl (CBS 322.89) and other lipases suitable for application in detergent systems is described in homologous, but particularly in heterologous hosts, e.g. Bacillus subtilis. For the latter a "helper function" or "lipase-specific stabilization/translocation protein" is needed, for which a gene is provided which, when expressed in concert with the lipase gene, can improve the stabilization of the intermediates involved in the production and translocation/secretion of the lipase. The hosts are transformed by recombinant DNA methods and modified lipases can be made by site-directed mutation or classical mutation techniques. The lipase gene and the gene encoding the helper function can be part of one operon that can be transcribed to form a polycistronic messenger or be present as separate genes yielding two mRNA's on transcription. The production level can be further improved by optimising the regulation sequences. It can be advantageous to use at least part of the signal sequence of the lipase gene in addition to a signal sequence homologous to the host in which the lipase is produced.
