Abstract: The present invention relates to novel bi-specific antigen-binding polypeptides and their preparation and use in the treatment and/or diagnosis of various diseases, and also relates to bi-specific antibody molecules capable of inhibiting immune effector cells and their use in diagnosis and/or treatment of various diseases.

Abstract: A portable winch assembly includes a winch mechanism connected to a support structure adapted to be manually transportable. A battery pack is releasably coupled to a remote control unit. The remote control unit is operated to control the winch mechanism. The battery pack and the remote control unit can be electrically connected to the winch mechanism by a flexible power cable, or the battery pack can be mounted with the winch mechanism and a wireless remote control unit can be used to operate the winch mechanism.

Abstract: A portable light is provided with a hook cylinder assembly which includes a retracting hook rod connected to a rotor assembly. The hook rod and rotor assembly can be rotated and held in position with respect to a remainder of the hook cylinder assembly. A hook located at an end of the hook rod can thus be oriented in a desired direction.

Abstract: A light flasher for an article of apparel includes one or more lamps that produce light visible from the exterior of the apparel. A switch, which may be of the mechanical or electronic variety, causes a switch closure responsive to motion of the apparel. A circuit, attached to the switch and the light, causes the lights to illuminate in a series of random duration flashes for a predefined time interval in response to the closure of the switch.

Abstract: Footwear for improving the visibility of the wearer includes a processing circuit that responds to operation of switch to turn a lighting system disposed in the footwear off and on. The switch is responsive to pressure from the foot of the wearer. When a wearer raises a foot from the ground, the lighting system is activated. When the foot is returned to the ground, or at the expiration of a predetermined period of time, the lighting system is deactivated.

Abstract: Apparatus is disclosed for mechanically assisting circulation of blood in a patient for periods of up to a week or two until the patient's heart strengthens sufficiently to take over the full workload. The circulatory assist device includes a valveless pump with a flexible bladder, a pneumatic driver for applying pressure pulses to the bladder, and a single flexible conduit for conveying blood between the patient and the pump. In use the pump and driver are mounted external to the patient's body and the flexible conduit is connected to the pump and in end-to-side relationship with a major blood vessel on that side of the heart, either right or left, which is in need of support.

Abstract: An actuator system for a dual path transmission usable with a vehicle, such as a crawler tractor or the like, wherein a pair of hydrostatic transmission units each have at least one power unit with variable displacement means therefor responsive to a control pressure for setting displacement, a control console mountable on the vehicle has a plurality of control valves including a ratio valve for setting a control pressure to establish the direction and speed of travel of the vehicle by uniform speed of both transmission units, and steer valves which may modify the speed of at least one transmission unit for steering of the vehicle, and a control station including a manually operable control member remote from the control console with motion-transmitting linkages whereby movement of the control member in one path may cause adjustment of the ratio valve for establishing the speed and direction of travel of the vehicle either forward or reverse and with movement of the control lever along an intersecting path ca
