Abstract: 245,981. Western Electric Co., Ltd., (Western Electric Co., Inc.). April 3, 1925. Transformers.-In transformers or repeating coils for use in telephone circuits in which air gaps are provided in the core to prevent an appreciable decrease in the inductance of the windings with increasing values of superposed direct current, the air gaps are symmetrically distributed with respect to the core and windings to ensure impedance balance between the windings for different values of superposed direct current. Fig. 1 shows a repeating coil in which! the windings 8 aro arranged on the central limb of a shell. type laminated core 3, one primary and one secondary winding being arranged on the upper part of the spool 6 and separated by insulating material 7 from the other primary and secondary windings on the lower part. The core is provided with symmetrically distributed air gaps and may, when the coil is to be applied to circuits carrying large values of superposed direct current, be built up from I- and C-shaped laminations arranged to leave complete air gaps 17 as shown in Fig. 4. An alternative arrangement for use on circuits carrying small values of superposed direct current comprises 8-shaped laminations assembled as shown in Fig. 5 to form partial air gaps 18. 19 at opposite ends of the centre limb. The laminations are clamped between plates 4 bent, to form brackets through which screws 12, 14 are passed for securing the core to a metal casing 13 and a lid 10 carrying the terminals 9, the screws 12 also serving as a means for attaching the transformer to a support.

Title: Improvements in or relating to apparatus for feeding cigarettes
IPC: A24C5/354
Filed: 1962-03-08
Abstract: 960,765. Delivering cigarettes in orderly arrangement. MOLINS MACHINE CO. Ltd., D. W. MOLINS, and D. T. N. WILLIAMSON. March 7, 1963 [March 8, 1962], No. 8970/62. Heading A2C. Apparatus for feeding cigarettes C into a hopper 6 so that they are distributed across the width of the hopper comprises a conveyer 1 to convey the cigarettes in a direction transverse to the direction of their longitudinal axes, attraction means to apply an attractive force between the conveyer 1 and the cigarettes C conveyed thereby so as to hold the cigarettes to the conveyer, the conveyer being arranged to move over the hopper 1 with the cigarettes C held to the conveyer while located beneath and suspended from the latter, and cut-off means to remove the attractive force so that cigarettes attracted to and suspended from the conveyer fall into the hopper across its width. The attraction means may comprise a suction chamber 5 to which suction is applied by means of a pipe 7 and valve 8. A reservoir 12 is provided for the cigarettes. In operation, when the stream of cigarettes reaches the right hand end of the hopper it operates a photoelectric device 10 which in turn operates the valve 8 to open the chamber 5 to atmosphere, thus releasing the cigarettes into the hopper 6. The rate of delivery of cigarettes into the hopper 6 is slightly greater than the rate of feed of cigarettes on to the conveyer 1 and the reservoir 12 is initially filled with cigarettes. As the reservoir empties, a pivoted plate 13 which rests on the cigarettes actuates a switch 15 to cause suction to the chamber 5 to be cut-off, the cigarettes then being fed directly from the conveyer 1 into the reservoir 12 to refill it, a suitable time delay being provided in the circuit of the switch 15. In alternative embodiments the attraction means are constituted either by electrostatically charged metal strips on the conveyer on to each of which a cigarette is fed, the strips carrying cigarettes on the underside of the conveyer being discharged periodically by a vertically reciprocating metal bar, or by an electrostatic field which is applied between the conveyer and the cigarettes.

Title: Production of polyurethane threads
IPC: C08G18/76
Filed: 1963-03-06
Abstract: The method of the parent Specification (wherein elastic polyurethane filaments are made by extruding a liquid polyurethane prepolymer which is the reaction product of a polyester having terminal hydroxyl groups or of a polyether having such groups with an excess of an aromatic aliphatic or cycloaliphatic diisocyanate in the form of filaments, into a setting bath consisting of 50 to 97% of an aliphatic amine having two primary groups and 3 to 50% of a hydroxyl containing solvent to effect a setting of the external surfaces only of the filaments to a solid state while the interior of the filaments remains liquid and thereafter setting the interior of the filaments to a solid non-porous state under anhydrous conditions at a temperature between 37 DEG C. and the melting point of the polyurethane) is modified in that the setting bath is maintained at a temperature of not over 135 DEG F. and that after being passed through this bath the filaments are passed through a second bath whose composition is as specified for the first bath, but which is maintained at a temperature which is at least 150 DEG F. and is at least 35 DEG F. above the temperature of the first bath, the interiors of the filaments being thereafter set to a solid, non-porous state under anhydrous conditions at a temperature between 37 DEG C. and the melting point of the polyurethane, for example, by heating the filaments to 65 to 205 DEG C. usually 80-150 DEG C. for a period of 1/2 to 30 hours, usually 1-18 hours, preferably at 90-120 DEG C. for 1-2 hours.  The diisocyanate may be an aromatic diisocyanate and the solvent in both the first and second baths may be water.  The temperature of the first bath may be 90-135 DEG F. and that of the second bath at least 60 DEG F. above that of the first bath.  The diamine may be ethylene diamine and the first bath may contain 70-80% and the second bath 75-85% of the diamine.  The filaments may be stretched to a greater extent in the first bath than in the second.  The spinneret is preferably positioned below the surface of the first bath. The polyester may be an ethylene-propylene adipate and the diisocyanate may be tolylene diisocyanate. A portion of the polyester or polyether used in the production of the prepolymer may be replaced by a tris polypropylene glycol phosphite which serves as a reactant, a heat stabilizer and a dyeability improver. The modified process of the invention prevents clogging of the spinning nozzle without deleterious effects on the properties of the final filaments.

Title: Improvements in or relating to electro-magnetic relays
IPC: H01H51/12
Filed: 1930-11-14
Abstract: 354,847. Rectifying alternating- currents. COVENTRY AUTOMATIC TELEPHONES, Ltd. and ERIKSEN, J., of General Electric Co., Stoke, Coventry. Nov. 14, 1930, No. 9082. [Class 38 (ii).] Contact-making relays which may act as rectifiers for producing A.C. impulses in automatic telephone systems comprise two parallel cores 3, 4 fitted with windings 1, 2 and adapted to attract alternately corresponding limbs of an armature 5 pivoted at 6. The armature has a third limb 8 extending between two sets of contact springs 9 with its free end engaged by a dead-centre spring 11. Thus when the armature is in either of its positions it operates the corresponding contact spring through an insulating projection 10 and is moved to the opposite position by energization of the corresponding electromagnet. In the circuit arrangement shown in Fig. 2, the relay acts as a continuous interrupter and produces current impulses in a controlled circuit. This is effected by spring sets 12, 13 each having two fixed and two movable contact springs in each set, the outer pairs completing alternately the circuits in the operating electromagnets and the inner pairs producing reversals of current in a transformer primary winding. Alternatively separate coils on the electromagnets 1, 2 may be connected to provide the A.C. without an additional transformer.
