Abstract: ABSTRACT OF THE DISCLOSURE         An automatic control system for the transfer of the drive power between a tractor and a trailer, which said system comprises a closed hydraulic circuit that operates the drive wheels of the tractor and an open hydraulic circuit that operates the drive wheels of the trailer.  In the system, the closed hydraulic circuit of the tractor comprises a pump and a hydraulic motor driven by the pump and, in a corresponding way, the open hydraulic circuit of the trailer comprises a motor or motors driven by a pump.  The control system comprises a line that transmits a control pressure from the closed circuit of the trac-tor to the open circuit of the trailer. When the resistance to traction increases, e.g. when driven up a steep hill, the pres-sure in said transmitting line increases and, by means of said pressure, the hydraulic pump of the trailer, which is advanta-geously an adjustable-displacement pump, is controlled to produce a higher pressure to the motor or motors driven by the pump.  In a corresponding way, when the drive power requirement of the tractor becomes lower, the operating pressure in the hydraulic circuit of the drive power transmission in the trailer is low-ered.

Abstract: A latch assembly for use in combination with slidable doors is disclosed. A rotatable disk is connected to the door so that the plane of the disk is perpendicular to the door and parallel to the direction of door movement. A lock bolt which projects from the door jam is adapted to engage a slot in the disk as the door closes, causing the disk to rotate. As the disk rotates, it slides with respect to a spring loaded latch bolt until the bolt slides through a second slot in the disk, when the door is fully closed. Efforts to effectuate a forced entry of the door cause the resulting forces to be passed primarily between the disk and the lock bolt, while the latch bolt's primary function is to prevent rotation of the disk. Thus, an attempted forced entry will not cause excessive forces to be placed on the latch bolt. The latch bolt is slidably connected to a conventional manually operated garage door handle assembly including a lock.

Abstract: The impulse welding device includes a transistor circuit which is operated by an impulse generator. The power transistors of the transistor circuit are operated alternately in the blocked condition and in the conducting condition. The transistor circuit is connected to a direct current power source in series with the arc which is created between the welding electrode and the work piece to be welded. The transistor circuit is shunted by an ohmic resistor which allows a spacing current to flow through the ignited arc during the impulse pauses. Since the power transistors are substantially completely blocked during the impulse pauses, the power loss will be decreased.

Abstract: A protective safety container (10) for encasing toxic drug filled glass vials (18) is disclosed. The container includes a molded plastic body (12) that is shaped to conform to the shape of a vial to be protected. A plurality of spaced longitudinal ribs (32) are formed on the inner surface of the container body (12) that act to engage the vial (18) and hold it firmly in position, and also form a cushioning air space between the vial and the container. A molded plastic annular base (14) is adapted to be snap fitted into the body (12) such that the vial (18) cannot be easily removed once it is secured within the container. Disposed in the top (15) of the container is a small aperture (26) having a frangible disk (28) disposed therein. The disk (28) may be removed so that a hypodermic needle may be inserted into a stopper (19) in the vial (18) to withdraw the vial's contents. The aperture (26) is too small, however, to permit removal of the stopper itself. All of these features combine to provide a protective container for a glass vial which will prevent the intentional or accidental discharge of the vial's contents to the surrounding area.

Title: Safety anchor for use with slotted beams
Inventor: OLSEN GENE E
IPC: E04G17/00
Filed: 1990-07-17
Granted: 1995-08-15
Abstract: A safety anchor including a pair of rectangular plates connected by a spring-loaded hinge assembly which normally biases the plates toward one another is a completely folded configuration. Each plate defines an aperture aligned with the opposing aperture when the plates are completely folded together. A double locking safety hook may be clipped through the apertures, and prevents the plates from being unfolded. Each plate includes a retention post fixedly attached thereto and extending outwardly beyond the rear edge of the associated plate. Each retention post has an enlarged head with two flat surfaces. The flat surfaces may be aligned with the slot in the beam and inserted therethrough into a recessed cavity when the plates are completely unfolded. When the plates are then folded together, the retention posts rotate relative to the slot and the enlarged heads become engagingly retained within the recessed cavity and behind the narrower slot. The spaced-apart retention posts prevent rotation or rocking of the safety anchor. During a fall, the plates of the safety anchor will cam against the face of the beam, and the hinge assembly will bear no load. Once the safety link is detached, the safety anchor may be removed and remounted on another beam using only one hand. The safety anchor is particularly suited for use with horizontal slotted beams and associated components utilized in erecting concrete pouring forms of the type referred to as "flying forms".

Title: Process for searching for synchronization on reception of a spread spectrum modulated signal
Inventor: CORNEC JEAN-PAUL
IPC: H04B1/707
Filed: 1990-11-14
Granted: 1994-04-19
Abstract: In a phase demodulator is received a signal of which the carrier is phase-modulated by a digital pseudorandom sequence itself phase-modulated by a data signal. A frequency close to that of the carrier is locally modulated by a sequence identical to the received sequence. The received and local signals are mixed into a filtered signal with an intermediary frequency band. A repetitive double integration step of the signal filtered into an integrated signal is used and is compared with a threshold in order to quantify the correlation between the received and local signals. Firstly, the local frequency  varies according to a few discrete values spread over the uncertainty range of the carrier corresponding to intermediary frequencies in the vicinity of the filtering band. At each discrete frequency value, integration steps are carried out for half-bit local frequency shifts. Synchronization of the sequences is acquired in response to an integrated signal exceeding said threshold at the end of an integration step. Then, the value of the carrier frequency is estimated by the average of numerous discrete local frequencies corresponding to favourable integration steps  and  included  in  a  band  centering  on  the  frequency  found  during synchronization of the sequences. The invention also relates to the closed-loop controlling of the amplification gain in correlators of the demodulator.
