Title: Trawl winches
IPC: A01K73/06
Filed: 1974-07-18
Abstract: 1472071 Winches P BJORSHOL [trading as P BJORSHOL MEK VERKSTED] 18 July 1974 [18 July 1973] 31971/74 Heading B8B A trawl hauling winch comprises two axially aligned independently driven drums 8 which individually wind on trawling tow lines which then together form a common drum hub on to which the trawl net is wound. The flanges 10 at the adjacent ends of the drums 8, are of smaller diameter than the remote flanges 9, to control spooling of the two lines but allow the net to extend thereover once the hub diameter is built up by the lines. A drive unit 2 including an hydraulic motor 21, gearing 22, 23 and axle 3 is positioned at each end of a base 1, of the winch, and each axle 3 is in gear mesh with internal gearing at one end of a sleeve 4, the other end of which is in free engagement with one end of an axle 5 extending between the two units 2. The adjacent ends of the drums 8 are freely supported on the axle 5 through an annular foot 11 on each drum. The lines are guided to and from the drums by pairs of guide rollers, the axis plane of each pair being at right angles to the drum axis.

Title: Modulation circuit arrangement for television
IPC: H04N5/40
Filed: 1937-11-20
Abstract: 494,459. Television ; modulating systems. RADIOAKT. - GES. D. S. LOEWE. Nov. 20,1937, No. 32002. Convention date, Nov. 21, 1936. Addition to 472,900. [Classes 40 (iii) and 40 (v)] In a further embodiment of the arrangement described in the parent Specification in which synchronizing signals are modulated on to a carrier in a stage which is completely neutralized and the image signals in a separate stage not wholly neutralized, the preliminary amplifier for the image signals is directly coupled to the image modulator valve. The Figure shows a generator 1 supplying a sub-harmonic of the carrier frequency to the class C amplifier 3 which acts as a frequency multiplier, the circuit 8, 9, being tuned to the required carrier frequency. Synchronizing signals from 7 suppress the emission of tube 3 and cause the cessation of oscillations in the output circuits. The image modulation is preferably performed in a five-electrode valve and in the four-electrode valve shown, may be performed either in the control or screen grid circuits. The screening grid of the image modulator 10 is connected to earth through the series resonance circuit 11, 12, and has its bias applied through resistance 16 from the glow lamp voltage stabilizer 29. Condenser 12 is somewhat detuned so that screening is incomplete and current flows in the circuit 14, 15, even in the case of blocked emission. Image signals from 20 are amplified in the valve 17 the anode of which is directly connected to the screening grid of 10. The valve 17 is normally traversed by a high emission current and has zero grid bias supplied by the leak 18. Any increase in anode current, which would result in the carrier amplitude falling below its bottom " black " limit, is prevented by the grid leak 18, or the diode 21 in the case of higher grid potentials. The danger of modulating the carrier down to an excessive extent may also be avoided by means of the potential 27 which ensures that the screening grid of valve 10 cannot fall below this potential. Emission current limitation and an improved characteristic in black may be obtained by the use of a screening grid 28 in the tube 10. The influence of the detrimental capacities of the screening grid of tube 10 and of the amplifying tube 17 is compensated by the use of a coil 23 with a parallel damping resistance 24 in the screening grid circuit. A similar damped connecting impedance 25, 26, has the advantage of also blocking high frequency from the modulating circuit. Instead of a four or five electrode valve, a neutralized triode may be employed for the modulation stage, the grid circuit including means for adjusting the residual coupling between grid and output circuits. The high frequency circuits such as 13, 14, 15 which transmit the entire side-bands of modulation are furnished with damping resistances of a valve derived from a formula given in the Specification and the capacity 13 is kept as small as possible, variable condensers being avoided by the use of variable inductance tuning.

Title: Method of increasing the useful life of paired members co-operating in rolling contact
IPC: C21D9/40
Filed: 1965-07-28
Abstract: At least one of the paired members of hardenable ferro-magnetic steel in rolling contact, such as rolling elements or races of ball or roller bearings, toothed gearing elements, rolling mill rollers or thermal expansion bearing elements for steel bridges, is heat treated to produce in its zone of main loading an inherent prestress acting in opposition to the loading by controlling an inductive heat treatment before and after quenching in such a way that a surface zone in rolling contact is austenitized more uniformly and to a greater extent than the underlying zones before quenching to form a different amount of martensite in the two zones, and after quenching a dilatation is produced in the surface zone by inductive drawing differing from that in the underlying zones. Maximum inherent stress is produced at a predetermined distance from the rolling surface depending on the resistivity and permeability of the steel and frequency of current flowing in the induction coil.  A roller not to be through-hardened (made of the steel: 1.0% C, 0.2% Si, 0.3% Mn, 1.5% Cr, balance Fe) may be cooled in a salt bath having a temperature of between 160 and 170 DEG C. followed by oil quenching between inductively heating and drawing.
