Abstract: A clamp for arrangement on a carrying arm is described. The clamp has a first and a second clamp half (10, 20) with in each case two lateral angle pieces (12; 21 ), in which are located a hole (14; 23) for positioning the clamp halves (10, 20) on the carrying arm, whereby the angle pieces (12, 21) which are directed against each other lie pairwise against each other and in each case one angle piece (21) of each clamp half (10, 20) lies on the inside and the other angle piece (12) of the same clamp half (10, 20) lies on the outside, and a legged spring (4) which lies between the clamp halves (10, 20) and keeps the clamps (3) closed. The internal angle piece (21) of one clamp half (10; 20) interlocks rotatably with the external angle piece (12) of the other clamp half (20; 10), and the legged spring (4) fills, in axial direction, the space between the internal angle pieces (21) in each case of the clamp halves (10, 20).

Abstract: A clamp assembly for attaching a pile to a device for inserting and/or extracting the pile. The clamp assembly has a fixed gripping assembly and a movable gripping assembly. The fixed gripping assembly is rigidly attached to a housing. The movable gripping assembly is rotatably attached to a pivot arm that is pivotably attached to the housing. The pile is placed between the gripping assemblies and a piston causes the pivot arm to rotate such that the pile is gripped between the gripping assemblies. The movable gripping assembly rotates relative to the pivot arm into a desirable position relative to the pile as it engages the pile to increase the ability of the clamp assembly to grip the pile. An anvil formed on the top of the clamp assembly facilitates attachment of the clamp assembly to the pile driving and/or extracting device and alleviates damage to the bolts used to attach the clamp assembly to the pile driving and/or extracting device.

Abstract: A secondary power system eliminates the need for an automatic transfer switch and permits simultaneous supply from different sources. Primary power is rectified and connected to a DC bus, an AC generator has its output rectified and connected to the DC bus, and a storage battery is also connected to the DC bus. Current on the DC bus is inverted to AC to provide an uninterrupted power supply. The system is connected to a household electrical system by a power distribution panel which can be installed in a home prior to the secondary power system and can facilitate installation of the secondary system. The distribution panel can selectively bypass the secondary system and can disconnect non-vital loads when primary power is not available. The generator is powered by an engine using gasoline, natural gas or water, which can also power other systems, such as air conditioning, with exhaust heat or rotary motion.

Abstract: A backpack having a waist encircling belt, and an attached set of shoulder straps which retract into a discreet pocket when not in use. There is a set of shoulder straps having clips on one end, and these are carried in, and attached to, a discreet pocket at the other end which is location on the outside, rear panel of the pack where the shoulder straps are readily accessible and can easily be drawn out and attached to rear side portions of the waist encircling belt. This provides additional support for the pack on an as-needed basis, and has the added benefit of being quickly and easily stowed when not in use.

Abstract: A supersonic airplane having four or two supersonic engines and one or more boost engines. During take-off and initial climb the supersonic engines are operated at a lower thrust setting within acceptable noise limits, and the subsonic engine(s) is operated to provide boost thrust to enable the airplane to operate a take-off and climb. During cruise, the subsonic engines are in a nonoperating mode, and the supersonic engines alone provide the thrust for supersonic operation. In one embodiment, one subsonic engine is deployed on one side of the fuselage during the operating mode. In a second embodiment, there are two subsonic engines deployed on opposite sides of the fuselage. In another embodiment, a single subsonic engine is installed inside the fuselage.

A control system allows a user to independently control the operation of the bagel cooker during the boiling and baking steps.

Abstract: Methods and compositions for protecting wooden members (components) against attack by destructive insects and fungi. The wood preservative is formulated as a paste and is applied in that form to an exposed surface of the member. The active ingredient is released by that same moisture which creates conditions conducive to destructive attacks on the wood. Boron-based active ingredients are preferred as are polyethylene glycol carriers for the active ingredient.

Abstract: An apparatus for applying spray texture to a wall or the like. The apparatus comprises an aerosol can containing pressurized spray texture material. The spray texture material is released from the can by a valve and passes through a nozzle passageway, out of a discharge opening, and on to a surface to be textured. The apparatus further comprises an outlet member that can be placed over the discharge opening to vary the effective cross-sectional area thereof. This outlet member can be in the form of a straw or tube that is inserted into the nozzle passageway or a disc or other member having a plurality of outlet orifices formed therein. The outlet member having a plurality of outlet orifices can be attached directly to an actuator member in which the dispensing passageway is formed.

Abstract: Methods of reducing NO.sub.x to nitrogen without using a reducing gas. The NO.sub.x is absorbed in a heteropoly compound to concentrate it and then heated to reverse the fixation reaction(s) and decompose the NO.sub.x into nitrogen.

Abstract: An energy-efficient, wood-skinned fire door having a laminate construction. There is a core panel formed of a fire-resistant material, preferably mineral fiber board. The perimeter frame around this has a channel formed in its inner edge for receiving the core panel in a close interfit therewith. This supports the panel in the channel, and also eliminates any direct path for a fire to proceed past the edge of the fire-resistant panel. Foil-covered thermal insulation panels are positioned on opposite sides of the core panel, and these are covered with wooden door skins. This provides a structure which is highly fire resistant and exhibits excellent insulation qualities, yet which is also aesthetically pleasing so as to be suitable for residential use.
