Abstract: 1,264,590. Harmonic gearing. USM CORP. 27 July, 1970 [5 Aug., 1969], No. 36265/70. Heading F2Q. In an harmonic drive mechanism, one of the surfaces of the gear members that are in contact during deflection is roughened so as to provide projections and the other surface is formed of an elastomeric material capable of being indented by the projections. As shown in Figs. 1 and 2, a flexspline 26, integral with an output shaft 28, carries teeth 30 which are forced into engagement with an elastomeric ring 36, secured to a housing 10, by an elliptoidal wave generator 20 secured to an input shaft 18. Instead of teeth 30, the flexspline 26 may be provided with knurling 32, Fig. 5, or serrations 34, Fig. 6. In a modification, a cup-shaped member 46, Fig. 3, is secured to an output shaft 44 and carries an elastomeric ring 48 for co-operating with spline teeth 50 formed on a flexspline 52 which is mounted in a fixed housing 40 by means of an elastomeric annulus 54. In another modification, an elastomeric ring 74, Fig. 8, is secured to a flexspline 70 and engages spline teeth 76 formed on the inside of a stationary housing 78. Fig. 9 shows a modification in which rollers 96, carried on arms 94 secured to a driving shaft 90, axially engage and deflect a face of a normally flat disc 100 mounted on an output shaft 106, thereby causing radial splines 102 on the disc 100 to engage an elastomeric ring 104 bonded to a housing 80. In a further modification, shown in Fig. 10, a wave generator comprises a pair of large balls 122, a pair of small balls 126, and two pairs of intermediate balls 124 located between a driving shaft 114 and a flexspline 134 secured to a casing 112. An output member 138 has a conical recess around the peripheral edge of which is secured an elastomeric ring 136 which is engaged by the flexspline 134, the contact pressure being determined by the axial position of input shaft 114.

Title: Textile yarn - incorporates metallic film to produce a reflective characteristic
IPC: D02G3/00
Filed: 1972-11-06
Abstract: A textile yarn having a surface coating of reflective metallic material (e.g. aluminium) is coated on its reflective surface with a thin layer of a copolymer including >=75% ethylene and >=1 monomer(s) of acrylic a acid methacrylic acid or acrylic or methacrylic alcoyl ester acids with 1-3 atoms in the alcoyl gp. Pref. the copolymer coating constitutes 1.5 gm/m of the yarn. A reflective coated polyethylene terephthalate film is coated on its reflective surface with a copolymer and laminated with a second reflective coated film between presser rolls such that the metal coating contacts the copolymer coating on the first film. The resulting laminated film is subsequently split into filaments. Alternatively a plastic film coated on both surfaces with a reflective coating is subsequently coated on both the surfaces with the copolymer. The copolymer coating prevents the yarn from being dyed during subsequent dyeing processors and also prevents degradation.

Title: Spud-shifting truck for dredger - has three drum winch with wire ropes for travel and lifting
IPC: E02F9/06
Filed: 1975-04-11
Abstract: The spud-shifting truck is for excavator-dredgers and other floating vessels being moved by a winch and wire ropes and despite the large adjustment range the spuds stays at the same height. After lifting by the winch rope the spud can make a free fall for its full length so as to penetrate the bottom. In heavier seas the spuds can be feed and the three drum winch used with anchors to improve production and efficiency. The design allows the spud to be dropped for a greater distance than where a hydraulic ram is used, since in the latter case the distance is limited by the ram stroke.

Title: Displacement of magnetic domain walls at high speeds - using gallium-substd. yttrium iron garnet in pulsed magnetic field
IPC: G11C19/08
Filed: 1983-09-15
Abstract: On a substrate of gadolinium gallium garnet, a film of gallium-substd. yttrium iron garnet is formed, by epitaxial growth from the liq.phase, with a pref. direction of magnetisation perpendicular ot the plane of the film. This element is placed in a gradient magnetic field (max. 6 kOe/cm.) thus creating a domain wall, and an auxiliary static magnetic field Hy of a few hundred Oe applied perpendicular to the domain-wall. using a coil connected to a generator, a pulsed, driving magnetic field Hz is created (build-up time 8 ns, repetition frequency 100 kHz) of max. strength 16 Oe. By means of Hy and Hz, the domain-wall can be displaced from one stable position to another, and with the aid of a polariser, analyser and photomultiplier, a ray of light passing through the film will be detected by the alteration in intensity due to the Faraday effect. The detection signal can be calibrated in terms of the wall displacement using ans oscilloscope and direct observation with a polarising microscope. The high speeds produced are suitable for use in data processing applications.

Patent NL-8901323-A (NL)
IPC: H04L9/06
Filed: 1989-05-26
Abstract: The invention relates to an encipher algorithm on the basis of a secret key, in which use is made of a substitution function, S(n,k), known as S-box, with which a series of n symbols (for example bits) can be replaced by a series of k symbols. On the basis of the secret key, an arbitrary S-box is always generated in order to avoid the use of preselected S-boxes. Such a generation can generally take place in such a way that the substitution result almost certainly does have non-linearity, but not, that it moreover has good statistical properties. These properties will be obtained, either dynamically (figure 1), if the bits of a temporary substitution result (contents of register 3) are moreover combined, via a modulo-2 adder 5, with the bits of a series with a good statistical distribution (contents of register 4) to the proper substitution result (contents of register 6), or statically (figure 2), if a series of n bits (contents of register 2 min ) to be substituted is combined with the k bits of a series with a good statistical distribution (contents of register 4 min ) to a series of n + k bits, which is subsequently substituted by means of a substitution function S{n+k,k} of S-box 1 min . The advantages are that a preselection of S-boxes with good statistical and non-linear properties can be dispensed with, and that the S-boxes always change and consequently are not known, which will benefit the strength of the encipher algorithm.
Patent NL-9000593-A (NL)
IPC: G06F7/72
Filed: 1990-03-15
Abstract: In cryptographic techniques which are based on the discrete logarithm problem, use is made of exponentiation modulo large number. If, in this method, the exponentiation is first carried out completely and the modular reduction is only carried out thereafter, this requires very considerable computation time and a very large memory capacity. It is known that the exponentiation can be accelerated by iteratively multiplying and squaring, with a modular reduction after each step. The invention provides a method of also accelerating the modular reduction at the same time, as a result of which the exponentiation modulo large number can be further accelerated. For this purpose, the invention describes a protocol for a modular reduction of a 2n-digit number x in a number system with base b to obtain an n-digit remainder, in which use is made of a specific modulus p which satisfies p = b<n> - a, where 0 < a < b. The method according to the invention does not reduce the security of the cryptographic system for which the modular exponentiation is carried out. <IMAGE>
