Abstract: 1,130,757. Side mounted mowers. INTERNATIONAL HARVESTER CO. 15 Nov., 1965 [2 Dec., 1964], No. 48399/65 Heading A1F. A tractor-mower combination comprises a tractor and a mower assembly including a reciprocable sickle assembly which is adapted to be attached to one side of the tractor. The tractor has front and rear mounting means on said one side, and the mower assembly has first and second fastening means for connection respectively to the front and rear mounting means. Fulcruming means on the tractor is positioned between the front and rear mounting means for fulcruming the mower assembly when one fastening means on the mower assembly has been secured to the respective one mounting means on the tractor, so that by adjustment of the connection between said one mounting means and one fastening means, the mower assembly may be canted about the fulcruming means for aligning the other fastening means with the other mounting means. As illustrated the mower has a forwardly extending arm 32 and a plate 43 which are connected respectively by bolts to a cam plate 18 and a portion (45) (Fig. 1, not shown) on the tractor the connecting means being such as to facilitate assembly and disassembly. During assembly the tractor and mower which is supported on stand 175 are first connected by a single bolt 26 at the end of arm 32, then forward movement of the tractor causes the plate 43 to engage the portion (45). A further bolt is passed through a lug 36 on the arm and the cam plate, and the holes of the portion (45) and plate 43 are brought into alignment by tightening or loosening the nut of bolt 26, the plate 43 being rendered vertical by adjustment of a nut (115) or rod (106) (Fig. 14, not shown). A U-shaped support 57, in the outer end (62) (Fig. 2, not shown) of which a housing 63 of the cutter bar drive is rotatably journalled, is pivotably mounted in members 46, (47) (Fig. 1, not shown). The member 46 is movable in a slot 60 thus a vary height of the arm 32 above the ground when the mower is supported on stand 175, or to vary the altitude of the cutter bar when the mower is mounted on the tractor and the stand is raised to broken line position. Raising the cutter bar and support is effected by a hydraulic ram 75 acting via linkage 82, 83, 85, rock shaft 86, lever 125, and chain 122. The rod (106) having adjustment nuts (115), and a collar (116) limits movement of the support relative to the plate 43. The outer end of the support is supported by a tension spring 98. The cutter bar is driven from the tractor p.t.o. shaft.

A rail vehicle for testing wagon boosting and retarding equipment which applies forces to the wagon wheels comprises a two-wheel trolley, each wheel 1 being mounted independently of the other at the lower end of a vertically disposed bracket 2 which is mounted on the trolley frame 3 to pivot at 4 about a horizontal axis, each bracket having a forwardly and rearwardly disposed surface 5 and 6 engaged by pressure sensitive load cells or transducers 7 and 8, held in place by wedges 10, which sense any pivotal movement of the brackets caused by boosting or retarding forces A or B. The load cells are connected to a recording instrument, not shown, which produces a graphic record of the forces on the wheels, Fig. 4 (not shown). In an alternative embodiment, each bracket may be associated with only one load cell which is pre-stressed to give a predetermined scale deflection for its normal position. The trolley is hauled by a locomotive coupled by the universal joint 13 and is loaded with ballast at 17 to prevent lifting. To assess the speed of the trolley a polygonal cam 19 which rotates with a wheel 1 causes a pivoted camfollower 20 to rise and fall and operate a micro-switch assembly 21 which is coupled to the recording instrument. An hydraulicallyoperated turn-table mounted beneath the trolley enables it to be lifted and turned round on the track, Fig. 3 (not shown).

A hollow beam, for example a roof beam, is produced by assembling two prefabricated concrete members 1, 2, each forming a side wall of the beam, in facing relationship separated by a distance piece 4, forming a joining wall 9 by concreting between the piece 4, which forms an inner shuttering, and an outer shuttering, and withdrawing the piece from the hollow in the beam when the concrete has set.

[Also in Division B7] An arrangement for normalizing a pulse train generated by the railway wagon identification detector described in Specification 964,570, comprising a D.C. restorer circuit for removing the base line variation in the pulse train and a circuit for standardizing in amplitude and rise time each pulse of the train. D.C. restorer, Fig. 2-The pulse train is applied via an adder circuit 20 to a transistor amplifier 31, 35 and thence to an amplifier including transistor 37 which is biased from point E at a level determined by the average D.C. value of the pulse train. This amplifier provides an output signal to amplifier 39 which consists largely of the base line variation plus a pulse ripple. The amplified signal is passed to a detector 43 having a time constant such that the circuit passes only the base line variation voltage and this after further amplification is applied via a voltage divider to the input adder in a sense to cancel the base line variation. Standardizing circuit, Fig. 3.- The pulse train minus its base line variations is applied directly to attenuator 54 and via delay line 51 to a second attenuator 61, 62. The attenuators reduce the pulse amplitude by half and are connected to an OR circuit 56 which supplies an output to comparator 57 which for each input pulse comprises an output pulse of half the amplitude commencing at the same time as the input pulse and ceasing the delay time introduced by line 51 after the end of the input pulse. The other input to the comparator comprises the input pulse delayed only by half the delay time of line 51. The comparator 57 includes difference amplifier T1, T2 and constant current source T3. T1 is normally conducting developing a voltage across R70 which is held constant by the clamping action of diode 72 and the baseemitter junction of T4 and this voltage develops an output voltage across the circuit output terminals. The transistors T1, T2 are biased such that when the voltage applied to the base of T2 rises to that applied to the base of T1 (i.e. the pulse half amplitude point) the transistors change over and the output voltage drops to zero. When the voltage on the base of T2 then drops below that of T1 (the other half amplitude point) the transistors revert to their original state. Thus for each input pulse a pulse of constant amplitude is developed having a width equal to the mid-amplitude width of the original pulse.
