Patent GB-550012-A (GB)
Abstract: 550,012. Printing-machines. NEWTON, E. P. (Telefonaktiebolaget L. M. Ericsson). March 19 1941. No. 3782. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug 25, 1941.] [Class 100 (ii)] In a postmarking or like machine the impressionroller is actuated by a mechanical relay comprising a pair of frictionally-driven discs which are tripped intermittently under control of a feeler actuated by the letters. In the mechanism shown in Figs. 1 and 3, a trip-arm 3 in the path of the letters is connected to a vertically-movable rod 19 by means comprising a link 8 and yieldingly coupled bell-cranks 10, 12. The rod 19 is connected to another verticallymovable rod 51 which is mounted in a rocking tube 52 provided with an arm 65 having yielding connection 32 with a lever 22 for, raising an impression-roller M into engagement with a printing-roller S. An arm 64 on the tube carries a mechanical relay comprising a shaft 63 which is driven continuously through a friction-coupling 61 by a shaft 62. The shaft 63 is provided with a pair of discs 56, 57, each having three teeth which alternate with the teeth of the other disc. A cam 59 on the shaft 63, and rollers 58 carried by the discs co-operate intermittently with a pair of driving- rollers arranged at opposite sides of the relay. The rod 51 is provided with a locking-tooth 55 for co-operating with a tooth of the disc 56 or 57. When a letter rocks the trip-arm 3, the tooth 55 is moved from the disc 56 to the disc 57, the shaft 63 turns through one-sixth of a revolution, the relay rocks the arms 64, 65, and the impression-rollers moved into engagement with the printing-roller. When letter-feed stops, the trip-arm 3 is raised by a pring 15, the rods 19, 51 are returned, the tooth 55 re-engages the disc 56, the relay returns the arms 64, 65, and the impression-roller is separated from the printing-roller. Specification 539,886 is referred to.

Title: Producing Conjugate Filaments by Melt Extrusion
Inventor: BRAYFORD JOHN RAYMOND
IPC: D01D5/30
Filed: 1967-12-05
Abstract: 1,179,615. Melt spinning conjugate filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 Nov., 1968 [5 Dec., 1967], No. 55311/67. Heading B5B. Conjugate filaments (which may be of the " side-by-side " or of the " sheath-core " type) are made by a process wherein the conjugate components result from the splitting of a single stream of a molten, fibre-forming polymer into individually metered sub-streams, modifying at least one of the sub-streams by incorporation into it of a metered proportion of a compound in the liquid state, said compound being capable under the conditions of melt extrusion of altering the melt viscosity of the polymer by reaction with it, thereafter bringing together the separate sub-streams to form at least one conjugate stream, and converting the conjugate stream or streams into conjugate filaments. The fibre-forming polymer may be a polyester and the liquid metered into one of the substreams of molten polyester may be a reactant capable under the conditions of melt extrusion of lowering the molecular weight and therefore the melt viscosity of the polyester. The polyester may be poly (ethylene terephthalate). The conversion of the conjugate stream into conjugate filaments may be effected by feeding the stream to a multi-hole spinneret adapted for the spinning of conjugate filaments or by feeding the stream to a straight or annular extrusion slot with production of a conjugate film which is thereafter slit to form conjugate filaments. The reactant used when the fibre-forming polymer is a polyester may be a glycol, a polyglycol, bis- #-hydroxy alkyl terephthalate, or an oligomer, which may be that of the polyester or of a second polyester. The reactant should preferably have a molecular weight of at least 500. When the filaments to be produced are crimped filaments the difference between the intrinsic viscosities of the polyesters in the two streams should be at least 0À05 units of intrinsic viscosity, this viscosity being defined as limit where C is concentration in grams per decilitre, # is the viscosity of the solution of the polymer and # 0  is the viscosity of the pure solvent, viscosity determinations being carried out in orthochlorophenol solution at 25‹ C. The normal melt-spinning temperature is about 280- 300‹ C. Conjugate filaments may be produced in which crimp is developed merely on subjecting them to the normal drawing stage or in which the crimp is enhanced or wholly developed during a heat treatment subsequent to the drawing stage.

Abstract: 1,174,084. Selective signalling. EVERSHED & VIGNOLES Ltd. 19 Dec., 1967 [19 Dec., 1966], No. 56766/66. Heading G4H. In a system for digitizing a pair of coarse and fine signals obtained for example from two potentiometers coupled by continuous gearing, first the fine signal is digitized, then the result, appropriately scaled, is subtracted from the coarse signal, and finally the resulting difference is digitized. This ensures that the coarse component that is actually digitized contains no fractions. As described coarse and fine amplitude significant signals are each converted to duration significant pulses, the fine signal is used to gate clock-pulses into a first counter, the complement of the count reached is transferred to a second counter, the coarse signal is used to gate clock-pulses also into the second counter which is arranged to produce a duration significant signal representative of the difference, and finally this duration significant signal is used to gate clock-pulses into the first counter, which then contains the required digital signal.
