Title: Phase change recording medium with high crystallization rate
Inventor: NAKAMURA NAOMASA
IPC: G11B7/2433
Filed: 2008-12-24
Abstract: An information recording medium includes a substrate 1, a phase-change recording layer 2 formed on the substrate, and a reflecting layer 3 formed on the phase-change recording layer. The phase-change recording layer contains tellurium and antimony or bismuth as main components, has a crystallization rate of 2 to 10 ns, and forms a recording mark by changing its crystal state when irradiated with a light pulse having half-width of 200 ps to 1 ns. The phase change recording layer can contain 38 to 42 at% Bi or Sb and 58 to 62 at% Te. The recording layer can also be a pseudo binary compound of (Bi2Te3)x(GeTe)1-x or (Sb2Te3)x(GeTe)1-x where 0.1   &  x   &  1. The high crystallization rate and short laser pulses enables writing without causing cross-erase and gives an amorphous mark almost equal to the track width with no recrystallization ring.

Title: Electromagnetic field energy recycling
Inventor: GRAY ASHLEY JAMES
IPC: H01F7/18
Filed: 2009-02-05
Abstract: An electromagnetic field energy recycling circuit recovers energy from a collapsing magnetic field of an inductor, stores the recovered energy as charge on a capacitance (C1), and subsequently re-uses the stored recovered energy to establish a magnetic field in the inductor. The capacitance (C1) and an inductance (L-1) are sequentially connected in various circuit configurations to recycle the energy by a discontinuous resonant energy transfer. In a magnetising configuration, a magnetic field is established by transfer of energy stored on the capacitance (C1) to the inductance (L-1). In a field energy recovery configuration, the capacitance (C1) is charged with energy recovered from the inductance (L-1) on collapse of the magnetic field. In a third configuration, the recovered energy stored by the capacitance (C1) is held until required for establishing a magnetic field. During the magnetising configuration, voltage on the capacitance (C1) drops by at least 50% and preferably to zero, and during the recovery configuration, current flowing in the inductance (L-1) falls to zero, thus maximising energy transfer and efficiency. The circuit can be used to drive electromagnetic devices such as electric motors, generators, transformers, solenoids, induction heating coils and inductive power transfer windings.

Patent GB-108312-A (GB)
IPC: C25C1/16
Filed: 1917-07-12
Abstract: 108,312. Electrolytic Zinc Co., (Assignees of Aldrich, C. H., and Bryan, J. K.). July 26, 1916, [Convention date]. Zinc and alloys, obtaining and depositing; electrodes.-In the refining of metallic zinc, with a slightly-acid electrolyte, the anode slime is kept in contact with the anode, in order to prevent dissolution of more electro-negative metals such as cadmium. From 0.1 to 0.5 per cent. of free sulphuric acid is a suitable proportion, but less may be used if the electrolyte is rapidly circulated. This acidity may be maintained by continuous or periodic additions, or by passing the electrolyte through a vat with an insoluble anode. The slimes may be retained by closely-fitting anode covers of canvas, duck, &c. of the kind described in Specification 108,311. The temperature of the electrolyte should be about 40‹ C. or lower. Iron may accumulate in the electrolyte up to about 1 per cent., and has beneficial effects on the deposit; any excess of iron may be precipitated bv zinc oxide in neutral solution. If cadmium accidentally goes into solution, it may be removed by circulating the electrolyte through a series of vats with insoluble anodes, to deposit the cadmium and part of the zinc. The Specification as open to inspection under Sect. 91 (3) (a) states that, in a series of vats having either soluble or insoluble anodes, the first vat or vats may be used for the deposition of zinc contaminated with cadmium, and the rest for the production of pure zinc, which is collected separately; anode envelopes may in this case be dispensed with. This subject-matter does not appear in the Specification as accepted.
