Title: Orally administrable corticosteroid preparations
IPC: A61K9/28
Filed: 1973-12-06
Abstract: 1458676 Corticosteroid compositions HOECHST AG 10 Dec 1973 [9 Dec 1972] 57090/73 Heading A5B A controlled release unit dosage pharmaceutical composition for oral administration comprises at least two layers, the word "layer" including a core in its meaning (e.g. drageÚ cores), each comprising a corticosteroid in the form of the free alcohol or an ester or salt thereof and each having different release properties. The corticosteroid may be hydrocortisone, cortisone, prednisone, prednisolone, methylprednisolone, or esters or salts thereof. Each layer may contain the same or different corti- 'costeroids, e.g. prednisolone in one layer and its acetate in another, or cortisone acetate in one layer and prednisolone in another. The preferred form is a dregÚe core such as a pressed tablet as the one corticosteroid-containing layer, having an enteric coat (e.g. cellulose acetate phthalate) resistant to gastric juice but soluble in the dudodenum, and an outer dragÚe coating containing corticosteroid, this coating being freely soluble in gastric juice to liberate its active ingredient for absorption in the stomach. The compositions are intended to enable the corticosteroid to be administered in such a way that its absorption rate and action is synchronised with the circadian rhythm of physiological ACTH secretion, and accordingly, the preferred form provides a small steroid dose immediately (i.e. from the outer, soluble layer), and a larger dose some hours later (i.e. from the inner, enterically coated layer), the dosage form being intended to be taken early in the morning. The invention includes a pack comprising a card carrying at least one pair of inventive unit dosage forms together with instruction that one unit is to be taken at about breakfast time and the other unit is to be taken between midafternoon and bed-time.

Patent IL-98963-A (IL)
Title: Residual echo elimination with proportionate noise injection
IPC: H04B3/23
Filed: 1991-07-25
Abstract: Residual echo from an echo canceler circuit is reduced by a variable attenuator that operates in response to a processing circuit which determines and adjusts an attenuation factor. The attenuation factor is determined by comparing relative levels of the send input signal, the receive input signal, and the error signal remaining after removal of an expected echo signal from the send input signal. The variable attenuator provides linear power attenuation of the error signal in order to reduce transmission of the residual echo signal and to eliminate the perception of coupling and decoupling of the telephone connection which occurs in known echo cancelers employing center clipping. A noise injection circuit provides a noise signal that is injected into the transmitted signal in inverse proportion to the attenuation of the error signal in order to provide a constant noise level in the transmitted signal as the error signal is variably attentuated.

Title: Magnetic recording medium
Inventor: NOGUCHI HITOSHI
IPC: G11B5/716
Filed: 1989-01-20
Abstract: PURPOSE:To impart traveling durability to the magnetic recording medium having >=2 layers of magnetic layers and to prevent the degradation in the electromagnetic conversion characteristics thereof by incorporating a specific ratio of a fluorine lubricating agent into the upper magnetic layer. CONSTITUTION:The upper magnetic layer of the magnetic recording medium provided with plural layers of the magnetic layers formed by dispersing a ferromagnetic material into a binder contains the fluorine lubricating agent at 0.1 to 5.0wt.% by the weight of the ferromagnetic material and the fluorine lubricating agent is incorporated into the lower layer at the ratio lower than the ratio thereof in the upper layer or is not incorporated into the lower layer. Namely, the lubricating agent amt. on the surface of the magnetic layers is controlled by incorporating the fluorine lubricating agent into the uppermost layer and the magnetic layers are smoothed by decreasing the content of the fluorine lubricating agent in the lower layer.
