Abstract: A modular wall construction includes a plurality of laterally spaced support posts having mutually spaced slots in commonly facing walls thereof, each slot being at least partially defined by oppositely disposed first and second edge segments. At least one panel is arranged between the support posts. In one embodiment, connecting elements are integrally formed with and extend laterally from the panel to overlie the commonly facing walls of the support posts at the slots. In an alternative embodiment, connecting elements are removably coupled to extend laterally from the panel to overlie the commonly facing walls of the support posts at the slots. The connecting elements have hook shaped portions received in the slots in engagement with the first edge segments thereof. A fastener extends into the slots between the connecting element and the second edge segments to coact in engagement with the slot and connecting element to prevent disengagement of the hook portions from the first edge segments.

Abstract: The invention provides an endless conveyor having a pair of gaps in its product conveying surface. As a film-wrapped product is conveyed across the gaps, a sensor aligned with the second gap signals the initiation of a shrinking sequence by which a pair of upwardly directed nozzles impinge hot air on the portion of film below and inboard of the transverse film seals. As the flow of hot air begins, a pair of magnetic clutches are activated to transmit power from a drive to a pair of shafts on which each clutch is respectively mounted. The drive, through the clutches, causes each of the nozzles to rotate about an axis so that the stream of hot air follows the travel of the wrapped product to maximize the time of hot air exposure without slowing the speed of product travel. At the end of the arc through which the nozzle is pivoted, the hot air flow is shut off, the magnetic clutches are deactivated, and a biasing spring causes the nozzles to return to their respective starting positions.

Also described is a cap to be used in the hand-held device. The cap has a substantially flat endwall defining a peripheral edge surface and a sidewall extending therefrom. The peripheral edge surface defines a radius which is substantially less than 0.040 inches.

Abstract: In the present invention, the exhaust gas from the engine is divided into a first and a second branch exhaust passages after it passes through a three-way reducing and oxidizing catalyst, and the two branch exhaust passages merge into an exhaust gas outlet passage. In the first branch exhaust passage, an oxidizing catalyst is disposed, and in the exhaust gas outlet passage, a denitrating and oxidizing catalyst is disposed.

The amount of NO.sub.x produced by the oxidizing catalyst and the amount of NO.sub.x flowing through the second branch exhaust passage is determined by the flow distribution ratio of the first and the second branch exhaust passages.

Abstract: When an apparatus for supplying power to an EHC becomes faulty, the supply of power to the EHC is shut off by a means which is separate from a control relay to prevent the catalyst from being overheated. The control relay that is opened and closed by an ECU is provided in a circuit that supplies electric power from a power source to the EHC attached to an exhaust gas passage of an internal combustion engine, and power supplied to the EHC is controlled by the control relay. When the control relay is short-circuited, this short-circuiting fault is detected by some means, and the power supply circuit is forcibly shut off so that power will not be continuously supplied to the EHC from the power source in this state. Means for forcibly shutting off the power supply circuit may be a relay, a breaker or a fuse when the power source is a battery, and may be to suppress the amount of power generated by an alternator when the power source is the alternator.

Abstract: An overspeed control for a hydrostatic transmission of a mobile machine includes a speed control valve arrangement connected to a fixed displacement pump through a supply line and to a pressure responsive displacement controller of a variable displacement hydraulic pump of the transmission. An overspeed control valve is connected to the supply line and is operative for reducing the fluid pressure level in the displacement controller when the speed control valve arrangement is in an operative position and the rotational speed of the engine exceeds a predetermined level. This reduces the displacement of the variable displacement pump (which acts as a motor in a downhill situation) and thus increasing engine retarding and transmission losses for preventing the positive grade from accelerating the machine, engine and/or the components of the hydrostatic transmission to speeds exceeding their designed limits.

Abstract: Clearance take up means is provided to take up the running clearance between the bed frame and slide of a progressive former at least near the end of the advance of the slide to top dead center, so that the advance is completed under essentially zero clearance conditions. A header slide system must allow a certain amount of running clearance to give room for lubricant and allow for expansion of the slide and bed due to variations in the temperature of the slide and bed. This clearance however compromises the concentricity of the work piece. The present invention enables normal running clearances to be maintained; however, near the front of the slide stroke clearances are eliminated completely by putting a side load on a system of wedges. This system reduces the side to side movement of the slide as well as the cocking about the vertical axis of the slide that occurs with offset heading loads.
