Abstract: 1392876 Transistor oscillators ELECTRONIQUE MARCEL DASSAULT 2 June 1972 [9 June 1971] 25978/72 Heading H3T In an oscillator, the phase shift in a closed feedback loop including a pair of interconnected transistors T 1 , T 2 ; T 1 <SP>1</SP>, T 2 <SP>1</SP> is caused to be 2# at a frequency higher than the cut-off frequencies of the transistors. An adjustable D.C. current source S may be coupled to the loop for determining the frequency at which the phase shift becomes 2#. In the symmetrical arrangement shown using a pair of oscillators high frequency voltages of opposite phases cancel out over portions 19, 191 and hence no high frequency voltage is present on supply line 18. In the embodiment of Fig. 1 (not shown), a single stage using the transistors T 1 , T 2  with their associated elements alone is used. The oscillator may be formed as an integrated circuit.

Title: Improvements in and relating to belt conveyors
IPC: B65G15/60
Filed: 1946-08-30
Abstract: 636,388. Endless belt conveyer. MILIK, R. Aug. 30, 1946, No. 26156. [Class 78 (i)] In a coal conveying system, the separate portions of a single endless belt are bent to form the radiating limbs (e.g. three) of a T- or Y-formation and an alteration in the length of one or two limbs is compensated by an alteration in the length of a remaining limb or limbs, the angle station at the junction of the limbs mounting rollers each formed of a plurality of closely-set, laterally adjacent and independently revoluble discs which combine to form for the roller a bulging contour corresponding to the cavity of the belt supported thereby. Fig. 1. The endless belt consists of portions T1, T2 and T3 and passes from end station A to angle station D, (formed of rollers of the type set out in Specification 599,182), to end station C, to end station B, to angle station D and back to end station A. The belt portion T, extends along the coal face and advances with the coal cutting machine, the coal being fed on to the belt at the advancing end station A and, after being discharged on to belt portion T2, is finally discharged in a crossroad at stationary end station B. The extra length of belt is obtained by the contraction of belt portion T3 so that end station C moves to a new position Cl. When the end station A has advanced to the end of the coal face, the belt T1, together with angle station D and end station A, is moved bodily to the left so that portion T2 decreases and portion T3 increases and then station A is again advanced or retracted along the new coal face. Fig. 2. This includes an additional end station E so that the belt now takes the course A, D, C, B, D, E, A. This prevents the coal-bearing belt face from contacting and therefore soiling the rollers of angle station D. Two such conveyers may be used side by side, one for taking out coal and the other for bringing in goaf. Specifications 590,008, 599,130 and 599,182 also are referred to.

[Also in Division F2] During the impregnation of oil-filled cable of the type in which longitudinal ducts for oil flow are provided beneath the cable sheath and in which a plug as shown is attached to each end of the cable 7, sealing of the oil passages on the far side of the sheathing press is achieved by means of the glove member 16. This member is resilient and is folded back as shown. When the plug is to be sealed the sheath is deformed by a hammer to approximately close the oil passages on to the cable side of the folded glove, the lead is cut behind the glove and taken off over the hauling cable so that screws 37 can be loosened and the hauling cable removed. The glove is unfolded over the cut end of the sheath 39 and held in position with flexible lips 34 and an oil reservoir is connected to adjuster 40. A similar process takes place at the cable trailing end.
