Abstract: A hand winch that includes a drum for carrying a strand wound thereon and including gear teeth, a drive gear having teeth thereon mounted in a driving relation to the gear teeth of the drum, and a handle assembly mounted on the drive gear for rotating the drive gear as the handle assembly is rotated. An engagement assembly 8 is positioned intermediate the drive gear and the handle assembly for winding the strand onto or off of the drum by the handle assembly when the strand is under tension and disengaging the handle assembly from the drive gear when tension on the strand is released to allow the drum to rotate while the handle assembly is stationary.

Abstract: A ventilation apparatus for arranging in a wall-surface region of a building. Such ventilation apparatuses are customary for so-called unheated sheds (stables, cowsheds, pigsties, etc.). In this case, an outer side of a shed building is closed against the entry of wind only with one or more tarpaulin-like wall elements, which are arranged one above the other and can be opened for more extensive ventilation of the shed by virtue of the fact that the wall element is wound toward the top like a roller blind. The object of the invention is therefore to provide a ventilation apparatus in which the wall element is opened by defined or controlled lowering of the top margin of the wall element while simultaneously winding the wall element and only by means of a single drive. This object is achieved according to the invention in that the wall element and the tension element together with further elements form a bow, ultimately more or less closed via the single common drive member, in which case the tension member itself is preferably unwound on the winding shaft to the same extent as the wall element is wound, or vice versa, specifically in opposite directions to one another.

Abstract: A hydrostatic system for controlling ventilation curtains in animal enclosures. A fluid-powered locking system is coupled by hoses to the winch assembly which controls elevation of the ventilation curtains. The locking system comprises a spring-biased piston associated with a rigid cylindrical casing. The casing is sealed by a rigid head and houses a flexible diaphragm which selectively contacts the piston. Fluid pressure is supplied to the casing via hoses coupled to the water line or other fluid source. Fluid entering the casing compresses the diaphragm, which in turn compresses the piston. The rigid piston rod is urged outwardly through the cylinder into frictional engagement with the winch spool. The cylinder at least temporarily locks the spool and thus the curtains at the desired position. A direct current powered solenoid valve maintains pressure to the system. When A.C. power fails, an electronic circuit having a variable timer maintains the system operational for a predetermined, user-selectable period. An alarm is activated to warn of an emergency condition. Thereafter, power to the system is shut off. The solenoid valve reverses, and fluid supplied to the system is vented. As a result, fluid pressure supplied to the piston decreases and the piston retracts out of engagement with the spool. When the spool is released, the ventilation curtains immediately fall, uncovering the windows to increase air circulation through the enclosure.

Abstract: A cable release for use in a curtain control system for controlling drop curtains in a livestock confinement building. The cable release operates with cable drop devices having a cord release. A U-shaped segment of a main cable attached to the drop curtains is held in tension by an anchor with a latch operated by a lock handle attached to the cord of the cable drop device. The curtains are dropped when the cord is released by the cable drop device and U-shaped segment is released from anchor.

Abstract: A method for controlling the temperature of an enclosure by opening or lowering curtains based on the difference between inside and outside temperatures and the prevailing wind velocity, direction, and wind chill. In one example, temperature of a cow barn is controlled, in part, by determining the direction from which the wind is blowing and using that and the wind velocity and internal and external temperatures to activate a controller to open or close barn curtains in order to warm or cool the barn. This invention can be applied to any livestock that is housed in any type of enclosure which makes use of automated curtains.

Abstract: Normally closed ventilating elements of a poultry building or the like are opened in response to failure of the supply of electric power to the building ventilating system by a control system which includes a source of direct current electricity arranged so as normally to energize an electromagnet and thereby to secure its armature to the electromagnet. The armature is secured to the handle of a winch which is arranged to operate the building shades. Power to the electromagnetic device is controlled through a MOSFET acting as a switch and which is controlled by a parallel combination of a capacitor and a resistor which are connected in parallel with the MOSFET gate. When power is lost, the capacitor discharges through the resistor and deenergizes the electromagnet so as to free its armature to rotate with the winch handle to open the building curtains.
