Abstract: A magazine cover is made with a perforated front cover which can be torn along the perforation to reveal the inside front cover while retaining the front cover on the magazine. This is accomplished efficiently by forming the front cover, inside front cover and back cover from a single sheet of material that is folded, perforated, and bound to the magazine pages to form the magazine.

Abstract: A high tension roller chain has sidebars which are contoured so that the sprocket can drive on both the roller and the sidebar or only on the sidebar, thereby permitting long stretches of chain to be driven by a single drive without damaging the rollers.

Abstract: A conveyor frame supports a chain which rides on small rollers, with a large roller projecting upwardly from the frame. The frame includes rails on which the small rollers roll. The rails are retained in the frame by spring pins, which fit into slots in the frame. The rails can be inserted into the frame from the top and can readily be installed and replaced.

Abstract: A bag for a frozen dessert dispenser includes a spout which has a tab which projects down into the bag to ensure that the bag does not cover the outlet opening. The spout also includes an indentation which mates with a projection on the dispenser to ensure that the tab is properly oriented in the dispenser.

Abstract: Fastening arrangement for securing a roller track (3) of a racking system to a support element (1,2), which support element (1,2) has a flange (4,6). A plurality of resilient tongues (5,8) are regularly spaced along and pressed out from the flange (4,6). The roller track (3) is releasably supported on and held between the tongues (5,8).

Abstract: A feeder-air lock provides a pair of slide gates, with the support for the slide gates and the mechanism for driving the slide gates located outside of the material passage, so as to provide a smooth, downwardly-sloping wall for directing the material downwardly without trapping or jamming material and so that the feeder-air lock provides a reliable mechanism which requires little maintenance.

Abstract: A vertical boiler with horizontal evaporator tubes is provided. The evaporator is divided into two sections, which are connected in parallel to the drum. The first evaporator section relies on the feedwater pump to provide forced circulation. The second evaporator section relies primarily on natural circulation but may also be assisted by the feedwater pump. This design provides a vertical boiler which is reliable under all operating conditions, including start-up, transient conditions, and steady state conditions, without requiring the use of circulating pumps or an auxiliary energy source (steam, water, gas, etc.).

Abstract: A concrete pole includes an attachment mechanism which provides a structurally sound means of attaching to the pole and permits the use of short, inexpensive bolts. It also eliminates the labor usually required for drilling or casting a hole through the pole to attach structural appurtenances to the pole with long through-bolts. The attachment mechanism includes annular members which are tied to the vertical reinforcing rods, a base plate, which is fixed to the annular members, nuts which are fixed to the base plate, and pipes, which provide a path from outside the pole, through the concrete, to the nut.

Abstract: A tool includes a frame and a cutting bar mounted on the frame. The cutting bar includes a plurality of aligned cutting heads. The tool mounts on a punch block, and the cutting bar is selectively aligned with a row of connectors on the punch block and is pressed downwardly to press and cut a row of wires.

Abstract: A golf club holder can be folded up to be carried in a golfer's pocket and can then be unfolded or extended so that its ground-piercing legs can be pushed into the ground. The golf club holder includes a clamp, having first and second clamping surfaces, at least one of which is movable relative to the other for clamping the golf club onto the golf club holder. The golf club holder is clamped onto the club and is then pushed into the ground simply by holding the grip of the club and pushing the club down until the head of the club rests on the ground. To remove the holder, the golfer simply pulls the club by its grip, pulling the holder out of the ground, and then removes the holder from the club. In this way, the golfer can keep a spare club handy without its grip getting wet and without having to bend down to pick up a club from the ground.

Abstract: A heat temperature rise door is made up of a steel shell and a core which is not bonded to the steel shell, thus eliminating much of the cost of manufacture of the door.

Abstract: A control device for controlling the time sequence activation of a wall mounted toggle switch is mounted directly to the toggle switch cover plate. The device is then programmed to turn the switch on and off in accordance with the programmed entry instructions. A sliding plate within the device contacts and moves the toggle into its on and off position in accordance with the program. The housing of the device defines an opening large enough for the toggle to be manually manipulated without removal of any components of the device.

Abstract: The rollers of a live roller conveyor are driven by drive wheels, which are driven from a driveshaft extending along the conveyor. When the drive wheels and their respective conveyor rollers are in contact with each other, the drive wheels cause the conveyor rollers to rotate. When the drive wheels and conveyor rollers are out of contact, the rollers are not driven and can accumulate product. Relative motion between the drive wheels and the conveyor rollers causes the drive to be engaged and disengaged.This is a Reissue of a Patent which was the subject of a Reexamination Certificate No. B1 5,375,696, dated Nov. 12, 1996, Request No. 90/003,811.
