Title: Improvements in or relating to mechanical looms
IPC: D03D49/68
Filed: 1956-12-20
Abstract: 846,714. Loose reed motion. MASCHINENFABRIK RUTI AKTIENGESELLSCHAFT VORM. C. HONEGGER. Dec. 20, 1956 [Dec. 20, 1955], No. 38921/56. Class 142(2). Upon each correct passage of the shuttle, a loose reed 11 is locked in the operative position by the pressure of cams 22, or 35, or 46, or 60, on brackets 18, 31, 41, or 52 which grip one baulk of the reed and which are pivotable about an axis 19, 32, 43 or 59, so positioned outside the plane of the operatively positioned reed that a plane containing the axis and tangential to the baulk at the side thereof remote from the reed, makes with the reed an angle α of between 50 and 130 degrees; but if the shuttle should be trapped in the shed, the cams release the brackets, which are then free to swing clear of the baulk. The free ends of the brackets are arcuate and may hold the baulk against a stop (Figs. 4 & 8) or locate it in both directions of swing (Figs. 5 & 6). The cams are mounted on a common shaft and may have shoulders 26 or 38 which, as the cams move into unlocking position, lift the brackets to reduce their grip on the baulk. When the reed has been thrown, the cams may be returned to locking position in order now to hold the brackets in their release position, as by cam noses 25 engaging under edges of apertures 24. In order that the reed shall be give a slight curvature, as viewed from above, the depth A of slots by which cylindrical members 43, about which the brackets hinge, are secured to the edges cut-outs 44 in the sley cap, may diminish from the ends to the middle of the cap: the same effect may be achieved by varying the length B of the brackets. The top baulk may be that held, Figs. 4, 5 & 6; or the bottom baulk, Fig. 8. In this latter case, the brackets are spring urged upwardly and, when the reed is thrown, it falls free on to the warp threads. The cam shaft may be actuated by a cam disc on the loom crankshaft, or from the crank arms driving the sley. Power may be transmitted to the cam shaft mechanically, electromagnetically, pneumatically or hydraulically. Locking cams may be reciprocated to and from locking position by a slide common to them all.

Title: Method and apparatus for effecting digital signalling over television signal channels
IPC: H04N7/085
Filed: 1973-08-17
Abstract: 1478960 Data transmission; PSK systems; television COMMUNICATIONS PATENTS Ltd 26 July 1974 [17 Aug 1973] 38926/73 Headings H4P and H4F A method of digital signalling over a television channel comprises phase shift keying the television carrier wave at line scanning frequency rate and determining at a receiver the phase of the carrier wave during each line relative to a datum and extracting a corresponding digital signal. In the embodiment described the keyed carrier is either in phase or anti-phase with an arbitrary datum in accordance with information to be signalled. Preferably the presence of line synchronizing signals are determined in order that phase shift may be imparted at a determined time relative to each scanning line. A high frequency modulated carrier wave television signal in a wired broadcasting system is sent to line through a PSK arrangement 1. Television signals also pass through a demodulator 4 and sync. pulse separator 5 and applied to a timing device 6 controlling a gate 8 which monitors the passage of digital information applied to terminals 9. By gating data signals, phase shifts are arranged to occur when they are least likely to produce any visible or other disturbing effects on television receivers. A preferred time is to effect shifting either during the back porch or line sync. pulses.  At the receiver (Fig. 2 not shown) the transmitted signal is amplified at 11 and passes to parallel circuits, a demodulator (12) from which video synchronizing and display circuits are derived to a receiver 13, and also to a phase locked loop (14) which also in known manner, is arranged to detect phase shifts which control data utilizing circuits (15). By utilizing each line it is stated that data may be signalled at a higher speed than former systems. For example, with 625 or 525 line standards, data may be transmitted at a rate of over 15kb/s.
