Title: Loom having a thread tensioner
IPC: B65H59/10
Filed: 1978-03-09
Abstract: In weaving machines, in which the weft thread (21) is drawn off intermittently from supply bobbins (V) arranged outside the shed and is shot into the shed by gripper members (G), a thread-tension device (S) is arranged between the supply bobbin (V) and the thread brake (B). By means of this thread-tension device (S), not only is the weft thread (21) fed under slight tension to the gripper member (G), but loop formation or twisting of the weft thread (21) between the supply bobbin (V) and thread brake (B) is also prevented. The thread-tension device (S) consists of a rotating drum (7) and of an annular brush (11) arranged freely displaceably on the latter. The thread (21) runs between the drum (7) and brush (11); the loose thread strand coming from the supply bobbin (V) is thereby wound as a loop on to the drum (7) and is drawn off from there during the next weft shoot-in. <IMAGE>

Filed: 1937-04-06
Abstract: 493,362. Converting. HARMER, H. M. April 6, 1937, No. 9693. [Class 38 (ii)] An arrangement for supplying a D.C. load from a single phase A.C. circuit comprises a pair of inductive reactances connected in series across the A.C. circuit, one having a condenser connected in parallel therewith, the reactances being connected to the D.C. circuit through rectifying means. The reactances are designed so that at normal load the voltages thereacross are polyphase. The arrangement can be made to give an output voltage which remains constant or increases with increase of load. Also constancy of output voltage with variation of input voltage can be obtained. In the form shown the two reactances are formed by two transformers 1, 2 having their primaries connected in series across the A.C. supply, a condenser 5 being connected across one of the primaries, and having their secondaries connected through Graetz connected rectifier groups 4 to the D.C. load 3. An autotransformer connection on the primary side of the transformer 2 may be used to enable the condenser to be supplied at a higher voltage. A three phase Scott connection arrangement is also described. Various type of rectifying devices may be used. The Specification includes an elaborate mathematical analysis of the invention.

[Class 40 (v)] Apparatus for detecting objects by the reflection of radio waves comprises in combination a radio-transmitter and co-operating. receiver, an aerial system adapted when energized by the transmitter to transmit sharplydefined overlapping beams and also to receive the reflected waves, and means whereby the aerial is associated alternately with the trans-- mitter and the receiver. The use of the same aerial for reception and transmission ensures that it is in the correct attitude for optimum reception of the reflected waves originally radiated from it, though they may be polarized at the source. The transmission and reception may be effected by a super-regenerative transreceiver such as that described in Specification 581,165. Preferably two overlapping angularly displaced beams are projected alternately in an interlocking signal rhythm as in the arrangement shown, in which horn radiators A, B on the wings of an aircraft are connected to a transreceiver TR by wave-guides which are alternately closed and opened by a rotating shutter RS. For three-demensional operation, at least three overlapping beams are transmitted. A dot, a short dash, and a long dash may be transmitted in cyclic succession by three overlapping beams. Actual or visual indicators may be employed for comparing the relative strengths of the components.
