Abstract: 1,135,843. Electric selective signalling systems; hotel reservations. TELOTEL Ltd. 21 June, 1967 [20 May, 1966], No. 22464/66. Addition to 1,055,186. Headings G4H and G4T. In a system comprising a plurality of outstations and a central station, each out-station when actuated transmits a sequence comprising a start pulse, address pulses identifying the transmitter, and information pulses, the pulses forming the address and information being equiweighted. At the central station the address pulses select a corresponding display for display of the information. As described, the stations are connected over the telephone network, the central station comprising an automatic answering machine. When the calling out-station receives the machine's reply the sequence mentioned above is transmitted, the information having been set up on switches. The central station includes a switching arrangement which passes the address pulses to appropriate uniselectors to select the required display panel, and which then passes the information pulses via a further uniselector which provides an output signal which is the binary form of the equiweighted information pulses.

Abstract: 946,954. Paper-making. ABSTERMO BRUKS A.B. June 21, 1961 [July 15, 1960], No. 22512/61. Heading D2A. The hollow forming roller 1, Figs. 2 and 3, of a wound-board machine, on which a cylinder of cardboard 50 is wound, comprises a bar 11, which can be moved, periodically to and fro, from a position in which it is completely retracted within an axial groove in the roller to a position in which part of the bar projects out of the groove. One or more nozzles (or slots) are provided at the rear of the bar, relative to the direction of rotation of the roller, through which nozzle or nozzles compressed gas, e.g. air, supplied through channels 14 (or 18) and 19 in the bar and one or more flexible tubes 22, is ejected at the surface of the roller when the nozzles emerge as the bar is moved partly out of its groove. A furrow or notch 26 is formed in the outer edge 12 of the bar, or between its front surface and the adjacent surface of the groove, or in the roller itself, preferably at least 8 mm. in front of the rear surface of the bar, to weaken the cardboard along a line substantially parallel to the bar. The outwardly moving bar pushes the cardboard away from the roller thus severing it along the line of weakness and gas is blown, from the nozzles between the roller and the severed cardboard, to loosen and facilitate removal of the latter from the roller which, after retraction of the bar, is effected by hand, by a grasper, or by an air-knife. The roller may comprise two or more bars 11. According to Fig. 4, nozzles 61 are provided in the shell 2 of the roller.

Abstract: 1484059 Cam followers; levers MIDLANDROSS CORP 19 Dec 1974 [26 April 1974] 22762/75 Divided out of 1484058 Heading F2K [Also in Division B7] A railway car coupler (see Division B7) comprises an automatic mechanism operative during uncoupling from a mated coupler to cause automatic pivoting of a rotor shaft 32, Fig. 2, and consequently unlocking and opening of a knuckle 12 of the coupler. The automatic mechanism comprises a lever member 42 biased by a spring assembly 44 for pivoting about the axis of a hub portion 61 such that when, during uncoupling from a mated coupler, the knuckle of the mated coupler moves to release pressure on the front face 46b of a plunger 46, the lever member 42 pivots to cause a roller 64 to engage a cam 40 and effect pivoting of the rotor shaft 32. As illustrated, the lever member 42 comprises: an arm 82, Fig. 8, bearing a trunnion 82a for engagement in a slot of the plunger 46; an arm 62 which has a bifurcated end carrying the roller 64; and a pair of arms 70 having recessed bearing portions 70a for receiving trunnion (74a), Fig. 4 (not shown), of the spring assembly 44.

In a guillotine having an adjustable back stop at least two spaced apart rollers on the same side of the blades as the back stop provide support for the part of the plate to be sheared which projects through the blades, the roller nearest the blades being provided with movable supporting means adapted to follow the vertical displacement of the upper blade during the shearing operation and having means for providing rotation of the roller during the upward stroke of the blades so as to impart movement to the cut-off portion of the plate away from the blades. The back gauge comprises a cross-bar 27 guided by slide bars 28 and displaced towards and away from the blades by cables 30 and 40 connected to a hand operated carriage 34 which moves along a graduated scale 35. The stop members 15 are pivoted to the cross-bar at 44 and maintained in the plane of the workpiece t by a roller 44b which runs on a member 46, which forms part of a parallel link system pivoted to the machine frame at 47a and to the movable blade carrier 16 at 48. Since one end of the member 46 is linked to the upper blade carrier, as the cut is made the stops 15 swing downwards and free the cut piece of plate. When the width to be cut off is greater than the maximum allowed by the stops 15, then secondary stops 50, mounted in the cross-bar 27, are used. The stops 15 can be raised above the plane of the plate by operation of a lever 49. The support roller assembly comprises a freelyrotatable roller 2 mounted on a bracket 13 which is adjustable along a bar 14, and a roller 1 mounted on an arm 4 pivoted to a bracket 12 arid also adjustable along the bar 14. Integral with the roller 1 is a gear-wheel 3 which meshes with a gear sector 11 secured to the bracket 12. The arm 4 also carries a roller which runs on a member 8 pivoted to the shear frame at 9 and connected to the upper blade carrier 16 by a link 7. As the cut is made the roller 1 descends and as the blade 6 returns the roller 1 rises and is rotated clockwise, as seen in Fig. 1, by the roller which runs on the member 8. A ratchet mechanism prevents rotation of roller 1 on the downstroke of the blade 6. The plate to be sheared is clamped by hold-downs 69.

The electrode of a magnetohydrodynamic generator comprises a base member having the surface adjacent the flow of working gas protected by an electrically conductive gas. The electrode structure shown comprises a base member 14 of graphite or refractory metal, e.g. tungsten or tantalum, with tube 20 through which gas is passed from inlet tube 18 in stem 16 to manifold 22. The gas comprising hydrogen or helium with potassium seeding material added passes out through a plurality of tubes on the upstream side of the electrode and thence passes between the electrode and the working gas. In a modification the base member may be made of porous electrically conducting material so that the protective gas diffuses through to the working face. In a further modification the porous insulating base member shields the conductive electrode from the working fluid, the electrical connection being maintained through the protecting gas. Specification 997,144 is referred to.

Abstract: 1286202 Bi-stable and astable transistor circuits TEKTRONIX Inc 13 May 1970 [26 May 1969] 23129/70 Heading H3T The condition of a tunnel diode 16 is responsive to input current I in  at 20, a load impedance 18 is connected to the input terminal 20, and a positive feedback such as T22, T32 modifies the input current in response to the current in the tunnel diode, in order to reduce hysteresis. As I in  increases, tunnel diode 16 switches to the low current higher voltage condition (45, Fig. 3, not shown), and T22 collector potential goes more negative. This increases T32 collector current and the potential at 21 tends to fall, some of the current through R18 and D16 being now shunted away to T32 and the working point moving to a lower current condition (45 to 50). Thus only a small drop in I in  is necessary (50 to 44) to cause the diode to switch back to the high current state (48), the positive feedback again tending to hold the operating point (48) near to the critical point (42) ready for further switching. R40 adjusts the hysteresis band by varying the low current stable point (50). If R40 is varied enough to move the low current point to the left of the peak (44), the circuit acts as an oscillator.
