Abstract: In a piston-cylinder unit having piston end-stop damping, which has a damping piston (31) projecting on the end face of the piston (15), which damping piston (31) can be moved into a damping chamber (32) provided on the facing cylinder end, forming a damping gap (38), in order to initiate a return-stroke movement of the piston (15), a flow path is provided which leads from the connection (25) for the hydraulic oil, bypassing the damping gap (38), to the compression chamber (40) bounding the main piston surface (29) of the piston surface (29), and contains a non-return valve (47). This flow path extends inside the piston (15) between an inlet opening on the front end (45) of the damping piston (31), designed as a hollow sleeve, and an aperture (55) leading to the exterior from the inner chamber (43) of this sleeve. <IMAGE>

Abstract: Such arrangements are used in the reactor pressure vessels of nuclear power stations in a remotely-controllable underwater design, using normal bolt threads and a special nut with a part having a deformable cross-section. In this case, additional components to secure the special nut 3 have been dispensed with, for safety reasons. According to the invention, the part whose cross-section is to be deformed and which is provided on the special nut 3, consists of a bead (5) on the free end of the special nut (3), supported by a thin- walled sleeve (4), and the nut thread extends without interruption through the sleeve (4) and the bead (5) as well and the bolt thread passes through the special nut 3 to the bead (5), it being possible for a compression piece (6) to press axially onto the bead (5) with a conically tapering hole (7) and the said piece (6) deforming the bead (5) plastically essentially in the radial direction, the bead (5) being pressed into the bolt thread as a result of its radial deformation. The arrangement according to the invention for positively-locked securing of screw connections against rotation is used inside nuclear reactors and is used there particularly for securing guide pins for fuel elements.

Abstract: The gist of the process for producing a poly­acetylene of the present invention is a process by which a polyacetylene which is stable even in an atmosphere containing oxygen can be produced by spreading on water surface a solution of a fatty acid series substance containing an acetylene or diacetylene group dissolved in an organic solvent, evaporating the organic solvent, gathering up molecules of the substance containing an acetylene or diacetylene group which remain on the water surface, in the water surface direction on the water surface by means of a barrier, and polymerizing the molecules in a state of monomolecular film on the water surface, i.e., Langmuir (L) film by the use of radiation such as X-rays, electron beams, γ-rays, etc. While applying a predetermined surface pressure, or by building up Langmuir-Blodgett (LB) films of an acetylene derivative into a film on a predetermined substrate under a definite surface pressure, and subjecting the LB films to polymerization by the use of such radiation as described above. 
     That is, the present inventors have found that a straight-chain, ultra-high-molecular-weight (ultra-­conjugated, high-molecular-weight) polyacetylene having a continuous conjugated system can be produced by subjecting molecules of an acetylene derivative to radiation poly­meriztation while compressing the same under a definite surface pressure.   
     Furthermore, the present inventors have found that when a DC bias is applied in the surface direction during the radiation polymerization of the L film or the building-up of the LB films into a film, a polyacetylene having a longer continuous conjugated system can be obtained.

Abstract: Image rendering time for an N x N pixel display is reduced from the order of N² to the order of M² + T i , where M is the size of an M x M matrix into which an image is rendered from a 3-D surface definition and M N, and where T i  is the interpolation time required to magnify the M x M matrix into an N x N matrix. Thus, it is possible to optimize image resolution versus rendering time.

Abstract: The present specification discloses a gas-fired appliance comprising a burner arrangement (37,39) for the combustion of gas with a valve arrangement (43) located in a gas flow line to said burner arrangement (37,39). To thus adjust the burner arrangement (37,39) a person must approach the appliance and manually adjust the valve arrangement (43). 
     The present invention provides a receiver (51) in the appliance, the receiver (51) being adapted to control the opening and/or closing of the valve arrangement (43) in response to signals received from a transmitter (53) operable at a position remote from the appliance. Thus the burner arrangement (37,39) can be controlled at a distance. This is especially useful for the aged and infirm, particularly with regard to gas fires. The present invention also provides a valve (1) which is opened by a surge current which then reduces to a value sufficient only to hold the valve (1) open against the force of a spring (21).

Abstract: In powered hand tools with tools rotating at high speed and plunging through a perforation in the baseplate, only the force of a restoring spring prevents the unintended plunging-through of the tool, which reduces the potential danger of the tool to the operator only to a limited extent. A locking means (locking pawl 40) to be released separately prevents the unintended plunging of the tool (14) through the perforation; a second locking means (locking slide 44) prevents the unintended opening of the hood (16), which is however necessary for changing the tool. Usable in all powered hand tools advanced in accordance with the plunging-saw principle. <IMAGE>
