Abstract: An apparatus for successive printing of cylindrical objects includes a driven carrying wheel; a number of spindles on the wheel freely rotatable about their longitudinal axes parallel to the axis of rotation of the carrying wheel; a printing station radially adjacent the path of the spindles for successively printing the objects; and structure for detecting possible absence of an object and connected to control and deflection structure for temporary deflection of the spindle path out of printing contact. Each spindle is carried by a carriage which can move radially of the carrying wheel and which is guided by a first guide member and a second guide member which cooperates with a guide groove for determining the path of the spindle carried by the carriage. Each spindle is carried such that the pressure force applied thereto during printing of an object can substantially be absorbed without moment by both guide members.

Abstract: A swash plate pump includes a housing and cylinders arranged in a circular pattern around the drive shaft. Piston rods are pivotally connected at one end to the swash plate and mechanism surrounding the drive shaft and axially slidable along it controls the angle of the swash plate. The opposite end of each piston rods is fixed to a piston. In one embodiment, each piston rod is locally reduced in cross-sectional area adjacent its piston to compensate for disparity in arcuate motions of the opposite ends of the piston rod and in another embodiment, the cylinders are mounted in ball joints in the housing to compensate the disparity. One end of the housing may be formed as a manifold and double seals are provided between the compression side and the drive side of the pump.

Abstract: The invention relates to a vessel which comprises a floating body upon which a seat for a person is mounted. The vessel is driven by human power through a treadle mechanism which drives a propeller.The treadle mechanism comprises two actuating elements which are each pivotable and are driveable by arms or legs and which are coupled by a driving shaft through a freewheel clutch. By avoiding the death centers which are present in a cycle treadle mechanism, human power is used efficiently.By making the floating body a gliding body the water resistance is reduced, so that together with the efficient propulsion mechanism a high travelling speed through the water is reachable.

Abstract: A majority logic voting system employs at least three magnetic AND gates, each having first and second inputs and an output. The first input to each gate is connected as the second input to another gate and the outputs are connected in common so that the gates are in parallel. A diode is connected between the first and second inputs of each gate. Further, an additional circuit may be connected to determine the current difference between the output of each gate and the second input to another gate.

Abstract: A bomb handling system includes a plurality of mobile frames, each having a pair of rails and carrying members on the rails. Each pair of carrying members supporting corresponding ends of a bomb and there being locking mechanisms with separate, common actuators at particular locations along the lengths of the rails selectively to arrest a pair of carrying members in transversely aligned positions at a location and to allow such pair to travel past a location. The mobile frames may be attached in a train with their pairs of rails in end-abutting relation and including blocking mechanisms which releasably prevent transfer of a pair of carrying members from one frame to the next. A mobile frame may include a mechanism to elevate its rails so that loaded and positioned bombs may be raised for attachment to an aircraft.

Abstract: The invention relates to a lamp fitting intended for attachment to a tube, rod or other elongate member, for example the bar of a sunshade, the lamp fitting comprising a ring which bears at least one lamp and which is to be arranged round the elongate member and attached thereto by means of attachment means, the ring having an inner surface extending over some axial distance and co-operating with the elongate member, which inner surface has a shape adpated to the cross-sectional form of this elongate member. The invention has for its object to give a lamp fitting a form such that it can be attached from the side in any required position to a tube, bar or rod, without it being necessary to slide it on from a free end part.

Abstract: A device is provided for applying a binding material around an object. The object is moved by a conveyor means into a length of binding material that extends across the conveyor path. The binding material is tensioned by a reciprocable tensioning means and the length of material fed to the conveyor path is determined by a brake means that halts the further supply of the binding material in response to a predetermined length of movement of the tensioning means.

Abstract: The invention relates to a device for packaging a row of covers placed coaxially of one another in a sheet of packaging material, comprising successively in the packaging direction: a feed station for the row of covers; a wrapping station for wrapping said row of covers in said sheet; a folding station for folding end wall and longitudinal fold edges of the sheet wrapped around the row of covers; and adhesive station for adhering fold edges to the packaging; and transport means for transporting the row of covers, which is characterized in that the folding station comprises gripping means gripping onto the wrapped packaging material from outside, which means hold the packaging material away from the row of covers during forming of the longitudinal fold.

Both of the second structure's arms are free floating and have their free ends connected to opposite ones of the first structure's arms.

Abstract: An ordnance piece is subjected to testing which approximates the time history of forces on the piece during actual firing thereof. A mass of predetermined weight is impelled to a predetermined velocity so that it attains a kinetic energy capable, upon deceleration to standstill, of imposing the desired time history of forces upon the brake and return mechanism of the ordnance piece. The force is applied to the muzzle of the barrel of the piece or to a dummy barrel and the energy transfer is effected in two stages of deceleration, the first stage being a cushioned stage and the second stage being a full impact or uncushioned stage. This results in a time history of forces acting upon the barrel in which the force increases from zero to a peak value and then decreases from this peak value to zero, thus approximating the actual time history of forces during actual firing of the piece.

Abstract: A plurality of struts are joined by hubs so as to be movable between a bundled, collapsed condition and an expanded condition in which the struts define at least one generally polyhedral or polygonal body. Pairs of the hubs are superposed to define split hub assemblies to hold the framework in expanded condition when joined.
