Abstract: PURPOSE:To absorb a difference of thermal expansion between a plug and a high pressure cylinder and provide complete sealing of the cylinder, by fitting the vertically movable plug to the cylinder at their tapered surfaces being reduced toward inside. CONSTITUTION:A high pressure chamber 5 for processing a work under high pressure is partitioned by a high pressure cylinder 1 and an upper plug 2 and a lower plug 3 projected on both openings of the cylinder. The lower plug 3 has a tapered surface 10 being reduced toward the chamber 5 and its corresponding surface of the high pressure cylinder 1 is also tapered and the plug 3 can ascend or descend due to the sliding action of both tapered surfaces. A seal ring 9 is fitted to the tapered surface 10. When a thermal difference is produced between the cylinder 1 and the plug 3 and accordingly a difference of thermal expansion between them, the differential expansion is absorbed through the axial sliding of the plug 3 to guarantee the hermetic sealing.

Abstract: Magnetic alloys are disclosed having an anisotropic magnetic structure produced by thermomechanical treatment in the absence of a magnetic field. Disclosed treatment calls for developing magnetic particles in an alloy by cooling such alloy in a controlled fashion from a first temperature at which the alloy is in a predominantly single phase state to a second temperature at which the alloy is in a multi-phase state. Treatment further calls for deforming the alloy, resulting in cross-sectional area reduction of at least 30 percent (corresponding to elongation of magnetic particles by a factor of at least 1.7). Disclosed treatment leads to desirable magnetic properties, e.g., in Cu-Ni-Fe, Cu-Ni-Co, Fe-Al-Ni, Fe-Al-Ni-Co, and Fe-Cr-Co alloys. For example, in the case of Fe-Cr-Co, alloy properties such as remanence-to-saturation squareness ratio in excess of 0.90 and maximum energy product in the range of 0.6-8.0 MGOe are achieved. Disclosed magnetic alloys are suitable for use in the manufacture of telephone ringers, relays, and electromagnetic transducers.

Abstract: A floor 1 or floor element 16, specifically for smaller houses and industrial premises, constructed from parallel lightweight girders 2 at a distance apart and gas concrete 3. The lightweight girders 2 serve as a load- absorbing element, whilst the gas concrete 3 acts as bulk- forming and surface-forming material. The lightweight girders 2 are wholly embedded in the gas concrete 3. This means that the risk of bulging of part-surfaces and rotation of the lightweight girders 2 is eliminated. The load-absorbing capacity of the girders is in this case limited only by the strength characteristics of the incorporated material. By choosing gas concrete 3 with low specific gravity and hence low heat transmission coefficient and girders with reduced cold bridge effect, a heat-insulating floor can be obtained. <IMAGE>

Abstract: In a stranding machine comprising a plurality of aligned, hollow shafts each having a pair of bobbins rotatably mounted thereon (one such shaft 5 and one of its bobbins 8 being shown), one bobbin of each pair being used for stranding whilst the other is winding up fresh wire and then the roles of the two bobbins being exchanged, a braking means (not shown) is provided to regulate the tension in the wire 2 as it is drawn from the stranding bobbin and guided into the hollow shaft 5 through which it is drawn to the stranding station. Thus, the wire passes over a pulley 41 carried by a lever 36, the movement of which under the action of the wire tension (opposed by a spring) is used to regulate a braking force on the bobbin 8. As the machine stops and the consequent reduction in wire tension is sensed, maximum braking torque is applied to the bobbin 8. For use of that bobbin in the next phase (rewinding) the brake is readily disengaged altogether. <IMAGE>

Abstract: A system for controlling the speed of a motor vehicle has a speed detector which produces a first electrical signal having a mean level relating to the actual speed of the vehicle and an alternating component whose amplitude is also related to the actual speed of the vehicle. A memory is provided for storing a second electrical signal which has a mean level related to the required vehicle speed and which is substantially free of any alternating component. A comparator compares the first and second electrical signals and therefore produces an error signal which has a mean level corresponding to the difference (if any) between the actual and required vehicle speed and an alternating component related to the actual vehicle speed. A servo responds to the amplitude of the error signal to adjust the actual speed of the vehicle towards the required value. A relationship-varying circuit varies the relationship between the amplitude of the alternating component of the error signal and vehicle speed and thus increases the overall gain of the system at higher speeds. A tuning circuit tunes the system so as to provide increased gain at a frequency at which the system tends to hunt.
