Abstract: A transport tray for use in an installation for manufacturing food products, the installation having actuators. The transport tray has a chassis and a bottom having two panels mounted on the chassis, each having a first parallel edge and being able to move in rotation about a rotation axis parallel to the first edges between a transport position in which the distance between the first edges is less than the diameter of the fruit products and an unloading position in which at least one of the first edges is lowered so that the distance between the first edges is greater than the diameter of the food products. Each panel cooperates with an actuator for passing it from the transport position to the unloading position. Apparatus is provided to prevent lifting of the first edge of each panel beyond the transport position.

Abstract: Electro-mechanical and electronically controlled access devices are described for controlling access to a building, premises or area in a secure manner such that a subject who is deemed ineligible for access will be barred entry and may be optionally retained. The devices can contain multiple rotatable door panels, which can be positioned behind one another. The door panels can be controlled by mechanized arms or other control devices in order to control the passage through the device. The direction of flow through a device according to these embodiments is electronically controlled and may be changed at any point in time. At any instant in time, the flow through the device is unidirectional. Multiple devices can be stacked together to form clusters, which can be controlled according to traffic, time of day, or other factors.

Abstract: A high-pressure mine door assembly for use in mine shafts configured with opposing wings, which enable the door to open and close quickly. The assembly includes a major hub and a minor hub positioned at or above the cap of the door assembly and coupled together via a connecting bar. A drive mechanism is coupled to the cap and the connecting bar, which facilitates the opening and closing of the wings of the door. The door assembly is configured in a 12-6 pitch orientation, requiring only a ? rotation of the wings of the door assembly to fully open the door. Such a configuration also negates the effect of air pressure on operation of the door, as regardless of the direction of the airflow, with the airflow assisting one wing in opening and the other in closing.

An erection assembly is selectively disposable in an assembled position exteriorly of the frame and supported thereon so as to facilitate the assembly of at least some of the frame panels and/or unit panels.

Abstract: A gate system (10) includes two spaced sides (12, 14) defining a work area (16) between the sides (12, 14). A first opening (18) is defined between first ends of the sides (12, 14), and a second opening (38) opposite to the first opening (18) is defined between second ends of the sides (12, 14). Two gates (82, 92) for opening/closing the first and second openings (18, 38) are respectively coupled with two shafts (40, 50) rotatably supported by one of the sides (12, 14). The shafts (40, 50) are rotatably interconnected wherein pivoting of one of the gates (82, 92) in a direction causes pivoting of the other gate (82, 92) in an opposite direction. Each gate (82, 92) includes a groove (85, 95) that receives a vertical beam (60, 62) of the other side (14) when the gate (82, 92) is in a closed position. Biasing elements in the form of gas cylinders (110, 120) between the side (12) and the gates (82, 92) prevent the gates (82, 92) from slamming into their closed positions.

Abstract: An entry control apparatus is provided. The apparatus includes a pair of spaced barriers forming a pathway therebetween. The barriers are positioned adjacent a doorway to control ingress into and egress from a building or the like. An arm is pivotally mounted and extends across the pathway and permits free movement of people in one direction and selectively restricts movement in the other direction. A motion sensor is provided and a motion control system is associated with the sensor. The sensor and motion control system cooperate to selectively allow the arms to move to a normally open position for normal traffic in an approved direction. In the event a person approaches the apparatus, as if to exit, or move in the wrong direction through the pathway, the sensor detects the movement and effects operation of the motion control system that locks the arm against movement to prevent movement through the passageway.

Abstract: A self-aligning, simple to use and reliable child/pet safety gate (2) that is removably mounted by a support assembly (4) to an existing room door (12) by hanging the support assembly on the room side doorknob (10) without the use of mounting hardware is disclosed. This design allows the gate to be used or stored while so mounted to the room door. Further, with the gate in its stored, hidden position behind the door, the existing room door can still be opened and closed in a normal fashion. Yet, it is a simple matter to place and secure the gate's blocking assembly (6) in its operative or blocking position by pivoting it to block the open area and then latching it to the door frame using a locking strap (54) and pin (60) and the existing door lock bolt aperture (62) to secure the blocking assembly.

Abstract: An access window for use in fast food establishments and other similar drive-thru business establishments is disclosed. The window broadly comprises a semi-manually operated closing mechanism along with two planar window members. The closing mechanism employs substantially flat circumferential grooves cut into rotors located in a bottom hinge assembly. These rotors, together with a flexible elastic linkage, enable the uniform and smooth rotation of the window members from a fixed closed to a fixed open position and enable the window members to be rotated from a fixed open to a fixed closed position when either of the window members are pulled or pushed a short distance in the direction of the closed position.

Abstract: A Door Control designed especially for a service passage in a cubicle disposed, say, at or near the entrance of a quick food establishment or the like, i.e., for serving customers on one side of the passage by an employee on the other side. This application is in part a continuation of my copending applications Ser. Nos. 78,095 filed Sept. 24, 1979, now abandoned, and 179,961 filed Aug. 20, 1980, now U.S. Pat. No. 4,411,102, which disclose and claim mechanism for simultaneously opening a pair of doors mounted on vertical parallel axes. In both of said inventions the door opening mechanism is characterized by a horizontally translatable device, such as a pushrod, by an operator's muscular force applied below the service table, leaving the hands free. Upon release of such muscular force, the doors are automatically returned to their original closed positions by means of energy stored, as in a spring, in the opening action.

Abstract: A stadium cover includes a pair of complemental compartmented canopies which are filled with a gas such as helium and which are moored or anchored by two or more winches to enable selective manipulation of their position. The winches act through cable sets that interconnect the winches with the canopies, and pulley means are provided to furnish several points for mooring and moving forces used in the control of the canopies.

Abstract: A mechanism for opening and shutting hinged doors, having special utility for discharge doors on silage elevators remotely operable by control ropes, which mechanism is firmly held in both open or closed position by gravity force holding the mechanism against a stop element which employ a door operating pulley, to one side of which is attached a control arm to open and close the door. The pulley is caused to rotate slightly past the point where said control arm is at its uppermost position when the door is opened and lowermost position when the door is closed and the stop means on said pulley prevents further rotation so that the door is held both open and shut by the force of gravity thereon.
