Patent DE-4205165-C1 (DE)
Title: Ring spinning frame - has electronic circuits in service unit to automatic ally piece up rovings to spun yarn with progressively improved performance
IPC: D01H15/013
Filed: 1992-02-20
Granted: 1993-06-24
Abstract: A process to automatically mend a broken end, on a ring spinning frame. The suction devices at each spinning position, hold the ends of roving. The service robot is arranged to deal with a large number of re-connections and has the air suction regulated accordingly. On a ring spinning frame there is a series of roving bobbins suspended from the creel above. The roving is fed into the drafting rollers, having the output rollers. From this point, a break in the roving, which emerges, and is still not spun is drawn by suction into the tube, which is one of a series at each spinning position on the frame. The amt. of suction available in the tube depends on the distance from the air extraction unit, and the number of tubes with roving in them. This variation is sensed at the service robot, which also utilises air suction along the tube, to bring together the spun yarn from the cop to combine with the roving. The correct amt. of suction to withdraw the roving from the tube is regulated by a logic device module. This is arranged in three sections. Firstly, assessment of the success rate initially, with secondly a memory to retain the preferred successful parameters, and thirdly a device to alter the amount of suction through the tube, as the robot progresses in a certain direction along the frame. ADVANTAGE - A successful and rapid re-connection of the roving to the yarn on the cop requires the service robot to withdraw the roving from the suction tube on the frame, which varies at each spinning position.

IPC: H01M8/2425
Filed: 1994-09-03
Granted: 1996-01-18
Abstract: A solid electrolyte, high temperature fuel cell arrangement consists of several directly contiguous fuel cells connected in series. Each fuel cell has two plane adjacent connecting plates and a solid electrolyte element (2) located between two connecting plates. The connecting plates of two adjacent cells connect the cathode (3) of one cell to the anode (5) of the other cell. In addition, the connecting plates have an air channel (4) and an air supply, as well as a gas channel (6) and a gas supply. The connecting plates are substantially vertical and the air and gas channels are open at the top for gas postcombustion purposes (9). Bending points and an irregular distribution of the load on the joints are thus reduced, so that sealing problems are solved. Air and gas supply are also simplified. Since gas postcombustion takes place above the cell arrangement, it no longer contributes to excessively heat the arrangement.

Abstract: Изобретение относится к области связи и может быть использовано в аппаратуре проводной многоканальной связи. Целью изобретения является повышение КПД системы электропитания и увеличение протяженности секции дистанционного питания. Это достигается тем, что в системе электропитания аппаратуры необслуживаемых пунктов проводной связи, содержащей источник постоянного тока с подключенной к нему проводной линией связи, в которую последовательно включены необслуживаемые пункты, на каждом необслуживаемом пункте последовательно в цепь дистанционного питания включен конденсатор, параллельно которому введена цепь, состоящая из последовательно соединенных дросселя и ключевого транзистора, к базе которого подключен выход блока управления, а параллельно ключевому транзистору включена цепь из последовательно соединенных диода и конденсатора, параллельно которому подключены вход блока и шины питания аппаратуры проводной связи. При изменении мощности, потребляемой аппаратурой необслуживаемых пунктов, изменяется величина напряжения на последовательно включенных конденсаторах и соответственно величина напряжения станционного источника и его мощность, что позволяет при неизменной протяженности секции дистанционного питания снизить величину потребляемой от станционного источника мощности и соответственно повысить КПД системы электропитания, а при неизменном выходном напряжении станционного источника увеличить протяженность секции дистанционного питания. 1 ил.
