Granted: 1993-10-19
Abstract: SHOPPING CART LOCKING MEANS                     ABSTRACT OF THE DISCLOSURE An infant carrier (2) for secure attachment of a shopping cart (4).  The infant carrier includes a seating section (5) for supporting the infant.  The seating section includes a bottom portion (6) and a back portion (8) disposed at an angle to the bottom portion.  Side portions (10) are located adjacent to and substantially perpendicular to the back and bottom portions.  Rear side extensions (12) are coplanar with the side portions, extending rearwardly therefrom, and include a lock (14) for securely attaching the carrier to a horizontal wire (20) of the shopping cart.  The lock is disposed on a rear surface (13) of the rear side extensions in an elongated opening (26) formed in the rear surface.  The lock includes a resilient cantilever member (28) connected by a connection end (32) at a lower end (30) of the opening.  A latch (34) is disposed remote from the lower end for retaining the horizontal wire within a recess (22) formed in the rear side extension.  To lock the horizontal wire in the recess, the infant carrier is positioned such that the latch contacts the horizontal wire. The infant carrier is pushed downwardly such that the horizontal wire exerts a force (arrow A) on the latch, pushing the resilient member into the opening.  The horizontal wire is thus received in the recess.  The resilient member is biased to its normal position such that an upper support surface (42) of the latch retains the horizontal wire within the recess.

Title: Feedback control system for the impedance control of an electric arc furnace
Inventor: ABERL HEINRICH
IPC: F27D99/00
Filed: 1991-12-06
Granted: 1996-05-28
Abstract: A feedback control system for the impedance con-trol of an electric arc furnace comprises at least one elec-trode, a hydraulic electrode actuator for adjusting the elec-trode, which actuator is adapted to be supplied with hydraulic fluid through a control valve, a controller, which is connec-ted to the valve actuator for the control valve, and impedance signal generator for delivering impedance signals to one input of said controller and a setpoint signal generator for deliver-ing a setpoint signal representing a desired impedance to an-other input of said controller. In order to prevent non-per-missible electrode oscillations in such a feedback control sy-stem it is proposed to provide a correcting stage for correcting the controller gain and to provide a correcting signal genera-tor for delivering to said correcting stage a signal which re-presents the controlled-system gain and which causes said cor-recting stage to change the controller gain in a sense which is opposite to a detected change of the controlled-system gain.

Title: Line monitoring for sdh signals
Inventor: BORSCHEL HARTMUT
IPC: H04J3/06
Filed: 1992-03-13
Granted: 1996-12-31
Abstract: Regenerator sections in known regenerators, which comply with CCITT-Recommendation G.958, are supervised by monitoring the transmission error probability of SDH          (synchronous digital hierarchy) signals, through determination of the parity. This requires the breakdown and restoration of the SDH signal. This requires special signal processing installations, not required for regenerating transmission signals, such as multiplexer and demultiplexer, which cause considerable loss of output. The regenerator (RE) according to the invention determines the transmission error probability by comparing a known word in the head part of an STM-N signal with a reference word. The transmission error probability is derived from the result of the comparison, and transmitted to a central unit via an error line (FL). For example, to transmit the transmission error probability in an STM-N signal, the service channel of a regenerator that complies wlth CCITT-Recommendation G.958 may be used.

Title: Circuit breaker for use in wall mounted plug
Inventor: BAER MARK
IPC: H01H50/20
Filed: 1992-05-15
Granted: 2000-11-07
Abstract: A circuit breaker includes a normally open switch having first and second contacts and a movable leaf spring supporting the first contact, The leaf spring is normally oriented in a first position wherein the first contact is not in electrical contact with the second contact. The leaf spring is deformable into a second position wherein the first contact is an electrical contact with the second contact. An armature is movable between an open and a closed position and is located adjacent an electric coil which generates a magnetic field which moves the armature into the closed position when the coil is energized.      The leaf spring biases the armature into its open position when the coil is not energized. The armature causes the leaf spring to deform into the second position, so as to place the first contact into electrical contact with the second contact, when the coil is energised.

Title: Insole with removable, height-adjustable support pads
Inventor: SARKOZI JEFF
IPC: A43B7/14
Filed: 1992-08-04
Granted: 1997-01-28
Abstract: A deformable,  elastic insole liner is provided with height adjustment pads for shoes to independently support the heel area, the longitudinal arch area, and the metatarsal arch area.  Each pad comprises a base pad and a plurality of thin stacking pads which completely overlay the base pad and any stacking pads, and are self stabilized thereby.  The stacking pads may be removably stacked onto each base pad, without requiring a fixed means of attachment to each other, in order to achieve the proper height adjustment for an individual user.  This enables an individual shoe to be separately height adjusted for any combination of heel, longitudinal arch and metatarsal areas.  In addition, after an initial adjustment, a particular support can be further height adjusted after a period of time, as necessary.  This enables the user to adjust a shoe to treat the initial support problem, and subsequently to readjust the support for ongoing changes in the arches and heel areas.
