As shown diagramatically Fig. 1 a pulley 13 is suspended from a jib block through a load cell 18 which gives an indication of the sum of the loads in falls B and C, the total load on a hook 17 being carried by four falls ABCD is therefore twice the value measured. Fig. 2 shows a jib top pulley arrangement with the load cells incorporated whereby accurate measurement of load is obtained irrespective of the angle of the jib, the load cells 23, 27 being automatically aligned with the direction of the force due to the load being weighed. A hoist pulley 12 is free to rotate on a shaft 20 rotatable in bearings 21 and the shaft has keyed to it a footstep 22 for the load cell 23. A shaft 24 carried in bearings 25 and with its axis in line with that of the shaft 20 has a footstep 26 for a load cell 27. The two load cells support a loading rig 28 which bridges a pulley 13. This pulley is free to rotate on a shaft 30, whose axis lies below the axis of the shafts 20, 24, and which is secured in a U frame 31 welded to the rig 28. Extending from the frame 31 are two pairs of arms 32 (Fig. 2) and (Fig. 3 not shown) each pair embracing extensions 33,35 respectively of the shafts 20, 24, and joined thereto by rods 34 which, by flexing, permit downward movement of the frame 31 thus influencing the load cells. As the jib angle varies the structure including the load cells and the pulley 13 so swings about the axis of the shafts 20, 24 that the axis of the pulley 13 and the contact between the load cells and their footsteps always lie in a common vertical plane. The use of one load cell instead of two is described (Fig. 4 not shown).

Abstract: 428,999. Ticket - issuing machines. COMLEY, C. W. A., Wilton Villa, Albion Grove, Stoke Newington, London, and PARKER, W. J., 46, Rushgreen Road, Romford, Essex. Feb. 14, 1934, No. 28994. Divided on 422,412. [Class 106 (iii)] A ticket printing and issuing machine for use on vehicles is adapted to print standard matter and changeable data upon portions of a strip in successive stages, by the operation of a common driving member provided with means for rendering the changeable data printing mechanism inoperative while leaving the drum printing the standard matter and feeding the strip operative. The strip is fed from a roll horizontally over a roller 8 until it emerges on the left of the machine. After the fare, stage, &c. settings have been made, the printing and other operations are effected by one rotation of a handle 27 actuating coaxial shafts 19<a>, 19<b> running lengthwise of the machine. These shafts rotate the standard matter printing drum 3 with transverse axis 15 and numbering mechanism, and reciprocate a carriage 62 with rollers 63 which press the strip upwardly into contact with the stage and class printing discs 4, 4<a> having longitudinal axes and the value and date printing discs 4<b>, 4<c> with transverse axes. The actuating shafts are normally connected by a clutch 38, 39, but the clutch can be disconnected by sliding the part 39 to the right on its shaft 19<a> by means of the lever 40, the upper end of which projects through the casing. The part 39 can only be moved into its disengaged position when shaft 19<a> and drum 3 are in their inoperative positions. In this way the standard matter printing drum 3 can be rotated to print and feed the strip while the changeable data discs are inoperative. The wheel 3 is driven by one-to-one bevel gear from shaft 19<a>. During part of its movement, that is approximately the second half of the cycle of operations with the shaft 19<b> disconnected, the strip 5 is gripped between the raised type and the roller 8 so that standard matter is printed and the strip fed forward. During the first part of the cycle of operations, with the shafts 19<a>, 19<b> clutched together, the strip is stationary and the changeable data on the previously set wheels 4, 4<a>, 4b, 4<c> is printed by the raising and the longitudinal reciprocation of the carriage 62. Pins 67 on the carriage engage grooves 68, 70 in fixed side plates, the pins normally engaging the downturned parts 70 of the grooves with the spring supported rollers 63 clear of the strip. The carriage is moved to the left and returned by a cam 56, 57 on the shaft 19<b> acting through a lever 59<a>.

A pulse generator comprises a blocking oscillator using a transistor 41 with feed-back via a transformer 42 and coupled to a further transistor 56 via a second transformer 39. The arrangement is such that transistor 56 is off when 41 is pulsing, but is made conductive by the energy stored in transformer 39 at the end of each pulse. As described, a line time base generator for a television receiver comprises a blocking oscillator 41 coupled via a transformer 39 to an amplifier 56, normally biased back by resistor 58. A positive pulse is produced by transistor 41 which is then cut off by the blocking action of capacitor 43 charging via the regenerative coupling transformer 42. The core energy of transformer 39 is now dissipated in the base current of transistor 56, so that bottoming occurs until transistor 56 is turned off by its self bias. Thus a positive pulse is generated at the primary of transformer 62, commencing with the trailing edge of the current pulse in transistor 41, and being extended by hole storage effects. The frequency of the blocking oscillator 41 is controlled by a phase comparator supplied with flyback pulses from a later stage (not shown) and with line synchronizing pulses. A D.C. reference voltage is fed from the slider of potentiometer 52 to the phase comparator. Resistor 49 forms a hold control.

[Also in Divisions G3 and H2] The rectified output voltage at terminal 02 of an oscillator constituted by a transistor T1 associated with a transformer TR is regulated by a feedback circuit which includes a resistor R and transistors T3, T4, T5 and which controls transistors T6, T7 arranged in the supply circuit to the oscillator, whereby the supply potential is varied in dependence upon output voltage variations so that the said voltage tends to remain at a constant value; additionally, the feedback circuit renders conductive a further transistor T2 should the output voltage fall to a pre-determined value below said constant value, as might occur at starting or on overload, whereby a bias voltage applied to the base of transistor T1 by way of transistor T2 and a resistor R8 is automatically changed to a value at which the oscillator is self-starting. Thus the need permanently to bias the oscillator so that it will start when switched on is obviated. The oscillator may be provided with a plurality of output connections such as 01 and 02, with or without associated rectifiers and may provide E.H.T. voltages for oscilloscope instruments and the like.
