Patent UA-118457-C2 (UA)
Title: Heated aerosol generating article with air-flow barrier
Inventor: MALGAT ALEXANDRE
IPC: A24F40/20
Filed: 2014-04-12
Abstract: A heated aerosol-generating article for use with an aerosol-generating device having a heating element comprises a solid aerosol-forming substrate and a breachable air-flow barrier assembled within a wrapper to form a rod. The rod has a mouth end and a distal end upstream from the mouth end. The breachable air-flow barrier is positioned, when intact, to substantially prevent air being drawn through the solid aerosol-forming substrate when a user draws on the mouth end of the rod. This decreases the propensity for ignition of the aerosol-forming substrate.

Title: Спосіб виготовлення адаптера магнітної плити металообробного верстата
Filed: 2017-11-20
Abstract: Винахід належить до машинобудування, зокрема до виготовлення адаптерів магнітних пристроїв, і може бути використаним для закріплення феромагнітних деталей на робочих столах металообробних верстатів. При виготовленні адаптера магнітної плити металообробного верстата здійснюють збирання пакета пластин з вуглецевої та нержавіючої сталі з їх почерговим розміщенням в стальному контейнері, котрий за формою та розмірами відповідає готовому адаптеру. Над набором пластин розміщують лист припою, закривають контейнер кришкою та приварюють її до стінок контейнера, після чого у ньому створюють вакуум та розміщують в печі, де його нагрівають до температури плавлення припою, витримують та охолоджують. При формуванні пакета застосовують пластини з вуглецевої сталі, довжина яких в 1,07 разу перевищує довжину пластин з нержавіючої сталі, при цьому довжину пластин з вуглецевої сталі вибирають рівною довжині готового виробу і пластини з нержавіючої сталі розміщують крайніми, впритул до бокових стінок контейнера, крім того, застосовують контейнер, товщина бокових стінок якого на 10-15 % перевищує товщину пластин з вуглецевої сталі. Технічний результат: виключення деформації пластин адаптера, досягнення високої точності міжполюсної відстані між пластинами, підвищення жорсткості готового виробу та мінімізація втрат металу.
Patent UA-123863-C2 (UA)
Title: Computer-based representation of precipitation
Inventor: KLEEMAN ALEX
Filed: 2016-04-26
Abstract: A method for estimating precipitation values and associated uncertainties is provided. In an embodiment, precipitation records that indicate the occurrence and intensity of precipitation at specific locations are received by a weather computing sys-tem. The weather computing system uses the gauge information to separately create multiple realizations of precipitation occurrence fields and precipitation intensity fields. The weather computing system may model the occurrence of precipitation by proposing a value for each point independently and using the proposed value to update all prior proposals. The weather computing system may model the intensity of precipitation by modeling the spatial correlation of precipitation intensity and sampling from distributions at each location to determine the intensity of precipitation at each location. The weather computing system may then combine the pre-cipitation intensity and occurrence fields into one or more final estimate fields.

Patent DK-14284-D0 (DK)
Inventor: FANTI HANSRUEDI
IPC: A47C23/06
Filed: 1984-01-12
Abstract: The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.
