Filed: 1955-05-09
Abstract: 769,042. Radio frequency coupling .arrangements. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 9, 1955, No. 13343/55. Class 40(1) The invention relates to an arrangement for feeding radio frequency signals from two separate sources to a common feeder cable. The separate sources may be aerials receiving signals in different frequency bands. According to the invention a circuit arrangement for the purpose specified comprises four inductors connected to 'form the four arms of a bridge, each inductor consisting of a conductor (1, 2, 3, 4) surrounded by ferromagnetic ferrite material (5, 6, 7, 8). The two inputs from terminals 9, 10 and 11, 12, are connected to the pairs of diagonally corners of the bridge D, B, and A, C; the terminals may be fed from aerials X and Y operating in different frequency bands. The output terminals 14, 15 of the circuit are connected to a further inductor coupled to the inductor in one of the arms of the bridge, as shown this consists of the conductor. 13 extending parallel to conductor 1 through the common ferromagnetic surrounding material 5. The ferromagnetic material is preferably in the form of a cylindrical sleeves as shown but may also be made up in the form of plurality of beads arranged along the conductors. A further inductor consisting of conductor 17 threaded through sleeve 6 may be included in the circuit and coupled to a load resistor 16 have a value equal to the impedance of the lead attached at 14, 15, this improves the symmetry of the bridge. When the bridge is balanced there is no mutual interaction between the signals from the two sources. The resistor 16 may be replaced by a second output lead if required and if three or four outputs are required additional couplings can be made to conductors 3 and/or 4 in the same way. If the characteristic impedances of the cables differ when more than one down lead is used symmetry may be restored by artificially loading the cables. Circuit arrangements of the kind described can be incorporated in a Band III television aerial unit and connected to an existing Band I aerial.

Patent GB-388605-A (GB)
Title: Improvements in the manufacture and production of porous rubber
IPC: C08J9/06
Filed: 1932-05-10
Abstract: Porous rubber compositions are prepared by the addition to the mix of 15-20 per cent of urea as a propellant before vulcanization.  The size of the pores may be controlled by varying the amount of urea added, by limiting the volume of the mould, and by varying the vulcanization conditions.  Their size is diminished by a reduction in the amount of urea added, preferably with a simultaneous increase in the vulcanization temperature, to a microporous condition suitable for the manufacture of rubber erasers.  These have the advantage that they require the addition of a smaller amount of factice than hitherto for softening purposes, with consequent improved ageing qualities.  In an example 15-20 per cent of urea give cells of 0,1-1 mm. in diameter when vulcanized at 122 DEG  C. for 45 minutes, having taken 45 minutes to reach this temperature, the moulds being two-thirds full.  To produce a microporous rubber the amount of urea was reduced to 7-10 per cent, and the temperature raised to 143 DEG C. for 50 minutes, the moulds being three-quarters full.

Abstract: 941,652. Hydro-mechanical variable speed gear; ratchet clutches; hydraulic torque converters. FORD MOTOR CO. Ltd. April 19, 1960 [April 17, 1959], No. 13690/60. Headings F2C and F2D. In a series arrangement of hydrodynamic torque converter and planet gear for motor vehicles comprising a carrier 20 which is connected to a turbine 14 and has interengaging planets respectively meshing a sun 19 connected to a reactor 15 through a one-way device 16, and an output ring 29 connected to an output shaft 31<1>, for towed-vehicle engine-starting centrifugal pawls 53 pivoted on the inside of the core of an input impeller 13 are, when the impeller is stationary or slowly rotating, engageable with ratchet teeth 58, 56 respectively on the turbine 14 and the reactor 15. In Low, an hydraulically actuated friction brake 37 stations the sun 19 and, through the one way device 16, the reactor 15, whereupon the turbine drives the carrier 20 and hence the output ring 29 at reduced speed. In Direct, an hydraulically actuated friction clutch 30 connects the output shaft 31<1> directly to input. In Reverse, an hydraulically actuated friction brake 24 holds the carrier 20 and the turbine 14 whereupon the turbine acts as a reaction member and the reversely rotated reactor 15 reversely drives the output ring 29 through the interengaging planets. In Neutral, the clutch and brakes are disengaged. Pivots 51 for the pawls 53 are formed by an endless steel wire inserted in grooves in the impeller or by an endless chain of individual cylindrical links. When towing the vehicle to start the engine the turbine is driven and its ratchet teeth engage and drive the impeller pawls 53 which, in turn, are engaged by the reactor ratchet teeth 56, the latter being arranged radially lower than those 58 of the turbine. The teeth 58 have sloping backs 60 acting as cams so that when the turbine is overrun by the impeller the backs 60 cam the pawls out of engagement with the reactor teeth 56. When the vehicle is stationary, whilst some of the pawls gravitate outwardly some, at least, fall inwardly for engagement with the teeth 56, 58. The impeller housing is provided with transmission cooling vanes 12. The ring 29 may be integral with or, as shown, gear-coupled to a flange connected to the output shaft 31<1>. The friction clutch and brakes are dry and may be of the plate or, as shown, friction-lined cone type.
