Title: Picking or Shuttle Actuating Mechanism for Looms.
Inventor: MYERS FRED
IPC: D03D49/24
Filed: 1918-12-19
Abstract: 130,877. Myers, F., and Clough, H. S. Dec. 19, 1918. Picking-motions. - The picking-stick is prevented from returning under the recoil of its retracting- spring if the picking- strap breaks. The stick is allowed to return after it reaches the end of its normal throw, but, if the strap breaks, the picking- stick drives beyond its usual throw, and is there held. For this purpose, a sleeve 7, Figs. 1 and 3, is mounted on the picking-shaft 5 and fixed thereto by a screw. In a vertical opening 7<a> in the sleeve works a spring-pressed bolt 8, which, when the stick 4 over-runs its usual throw, enters a notch 10 in the bearing 9, thus locking the stick in this position. The stick may thus be prevented from coming into contact with the healds, and the broken strap 3 prevented from flying back. In another arrangement, over the picking-stick 4, Fig. 4, is mounted a catch 11, which limits the forward motion by the part a and prevents return by means of the part b.

Title: Method of and apparatus for increasing the amplification of electric signal impulses by regenerative means
IPC: H04L25/04
Filed: 1926-09-04
Abstract: 277,167. Herbig, H. F. Sept. 4, 1926. Systems employing selenium cell and like relays.- Direct current signals received over the cable A are communicated to a relay or recorder 16 through a photoelectric cell system so arranged as to produce feed-back or regenerative reaction. In the example shown the signals pass from the cable A to the artificial line AL through a galvanometer 1, a beam of light from whose mirror 2 normally produces an equal degree of illumination in two photoelectric cells 4, 5, through which a current circulates from the battery 6. Movement of the galvanometer mirror alters the relative illumination of the two cells, and so varies the potential of the grid 9. A change is thus produced in the plate current of the valve 7, giving rise to an induced current in the secondary 19 of a transformer. The connections are such that the induced current aids the current through the galvanometer 1 : a regenerative action is thus obtained. The filament current is regulated by partially short-circuiting the filament resistance. The photoelectric cells may be of the case type, comprising a vacuum tube containing argon or helium and provided with two electrodes one of which is coated with barium.
