Filed: 1926-08-17
Abstract: 279,195. Croad, A. K., (Mill Devices Co.). Aug. 17, 1926. Addition to 203,368. Knot-tying devices.-The rocking strand-positioning members of the parent Specification and the tying-bill are operated in sequence by a cam whic.h releases the strand-positioning members during the operation of the bill. The frame of the knotter comprises side-plates 10, 11 spaced apart by screws and supported in the hand by a handle 14 with a strap 15. The strands a, a' to be knotted are received in notches in the side plates and are moved one inwards and the other outwards prior to the rotation of the knotting- bill by rocking members 30, 31 and their actuaing links 34, 35. The knotting bill comprises clamping and cutting jaws 25, 26 and an intermediate pivoted shearing jaw 27 having a lever extension 29 which contacts with the side of an opening in a yoke 16 through which the bill projects eccentrically, so that on rotation of the bill the jaw is operated. The bill has a shaft having a flattened helically twisted portion which is engaged between a pair of arms 42, 43 rigidly connected to a pivoted hand-lever 41. The links 34, 35 are connected by a rod 36 hung from radial arms 38. The rod 36 is movable in slots in the side plates. and is engaged by a cam 44, secured on the arm 42, which is formed with a notch 45 and a portion concentric to the pivot of the arm so arranged that on movement of the lever 41 the notch 45 first causes the actuation of the links 34. 35 before the rotation of the bill and then, owing to the concentric portion, prevents further movement of the links until the rod drops into the notch on the return movement of the lever. Fingers 40, 40a are formed on the links 34, 35, and when the links are moved these engage the strand a and move it outwardly while the sockets 30, 31 engage the strand a and move it inwardly. The subsequent rotation of the bill unites the strands in a weaver's knot, the sequence of operations being similar to that described in the parent Specification. The blade 27 cuts one of the strands and the other is cut by a blade 48 carried by an arm 47 having cam extensions 52, 53, which are engaged by a roller on the arm 42. An extension 51 of the arm 41 ending in a hook 55 engages the united strands. strips the knot from the bill and tightens it.

Title: A new or improved motion indicator and control for colliery winding engines
IPC: B66B19/06
Filed: 1925-08-14
Abstract: 259,711. Drummond, M. Aug. 14, 1925. Mechanical telegraphs.-A member 8 controlling the winding-engine is connected to two members 2, 3 operated by the " onsetter " and " banksman " respectively, so that until at least one of these members has been moved into a certain position the control member is not operated. The members 2, 3, 8 take the form of slides and a transverse member 10 pivoted to the control member 8 passes through slots m the other two members so that it has a certain amount of lost motion. Thus the member 8 is not raised until both the slides 2, 3 are raised. Links 12, 14 and a bell-crank 13 connect the slide 8 with a shaft 15 carrying a locking-arm 16 for the starting lever 19 and a lever 24 connected to a treadle 22 that carries a locking device 20 for the brake lever 21. A shaft 25 turns through 180‹ on the ascent or descent of the cage, and a disc 26 carried by the shaft has two notches 27 to allow an arm 28 on the shaft 15 to move only when the cage is at the end of its movement. An arm 29 on the shaft 25 trips an arm 30 connected to a link 32, operating a crank 43 to release pawls 40 that hold the slides 2. 3 in their raised positions. The pawls can also be released by levers 45 operated bv connections 44, 50 when the onsetter and banksman wish to withdraw their signals. A bell 60 may be operated by the movement of the control member, and movable panels 58, 59 are fixed to the slides 2, 3 so as to appear behind apertures 55, 56 in the casing 1 when the slides are operated. A fixed panel 57 of a different colour from the panels 58, 59 is mounted behind the apertures. The movement of the shaft 15 is controlled by a weight 34 and a dash-pot 35.

Patent GB-1083093-A (GB)
Title: Polycondensation apparatus, process and polymer
IPC: C08G69/04
Filed: 1965-05-14
Abstract: <PICT:1083093/C3/1> Polycarbonamides are continuously produced by feeding continuously a liquid-solvent solution of polycarbonamide-forming reactants to (referring to Fig. 1) an evaporation vessel 10 by line 11 through a spray device 16 and through a liquid-vapour contacting system 17 for intimately contacting the feed reaction mass solution with any vaporized components of the reaction mass resulting from the concentration of the reaction mass solution in evaporator 10 and the polycondensation in reactor 18.  The reaction mass is heated to above the b.p. of the solvent by heating coils 12 which are supplied with an inlet line 13 and an outlet line 14.  Solvent vapour resulting from the concentration of the reaction mass may be removed via line 15.  A portion of the enriched reaction mass leaves evaporator 10 by line 20 and is fed continuously to a heated reaction vessel 18 having a liquid phase and a vapour phase within.  The volatile products resulting from the polycondensation reaction, such as residual water of solution, water of reaction and the vaporized diamine used in the reaction are removed continuously from the reactor 18 by line 19 for return to the process in the evaporator 10 in the vapour space above the heated liquid reaction mass solution and below the liquid-vapour contacting section 17.  After a time in the reactor 18, the partially polymerized material is removed continuously through line 25 to a pressure reduction unit or flasher 26, wherein occluded water and other by-products in the liquid mass are evaporated or flashed from the mass at atmospheric pressure thereby permitting an increase in the degree of polymerization. The viscous mixture is then fed to a prefinisher 31 wherein thin films of the mixture are formed to permit the escape of residual solvent and by-products in the vapour phase via line 32.  The thin films are heated and the reaction mass passes via line 35 to the finisher 36 through which inert gas flows at line 38 counter-current to the flow of the reaction mass.  A heating medium enters the finisher at line 39 and exits at line 40.  After a time in the finisher polymers exit by line 37.  The liquid-vapour contacting section may be composed of ceramic saddles or Raschig rings.  A polymer prepared from a 45% aqueous solution of hexamethylene diammonium adipate is exemplified.

Abstract: 1434603 Infra-red scanning from aircraft SOC ANON DE TELECOMMUNICATIONS 1 May 1973 [5 May 1972] 20701/73 Heading H4F In an airborne line by line infra-red scanning system, a mirror 21, Fig. 4, rotating about the aircraft's nose-tail axis 22, performs line scans of the overflown terrain with respect to a detector 25 along lines transverse to the direction of flight, the "frame" spacing of the lines being caused by the aircraft's motion. The "local" horizontal of the aircraft is defined by a plane containing the mutually orthogonal mirror axis 22 and reflected beam path 23. If the aircraft rolls by an angle #, i.eÀ an angle # appears between the vertical line 26 and a line 29 perpendicular to said plane, successive line scans are no longer aligned. To overcome this, a gyrometer having an input shaft aligned with said "nosetail" axis and an output shaft perpendicular thereto, provides an indication of the rate of change of roll. This indication is integrated (12) Fig. 2 (not shown) and corrected for an D.C. drift by a slow or fast rate retroactive loop (10). The resulted indication of roll is used Fig. 8 to control the duration # 1  of a pulse started by a synchronized pulse (1) when the mirror angle α Fig. 10, with the local horizontal is zero and stopping when where is the desired semi-angle of scan. Said pulse (2) is used by its trailing edge to start an enabling pulse of duration i.e. starting at and finishing at The enabling pulse (3) applied to the video signal to light converter 33 providing scanning illumination of a film 34 moved in synchronism with the aircraft's flight, ensures that the repoduced infra-red image is formed from correctly aligned line scans.
