Title: Carrier with bale stacking apparatus
IPC: A01D85/00
Filed: 1970-07-15
Abstract: 1323722 Stacking bales; loading agricultural vehicles P T TAYLOR 15 July 1970 [15 July 1969] 34244/70 Headings C5F and F23E1 Bales 2 of hay are fed from a baler up a ramp (6), Fig. 2 (not shown) to be directed by an arm 12 into a trailer 1 to form a stack on the trailer deck 55 which may be tipped to release the stack. The arm 12 is mounted on bearings 28 on a horizontal shaft 29 supported on the trailer 1 and comprises an upper section 32 and a lower section 31. The upper section 32 comprises an edge 13 and pivotable plates 37 and the lower section 31 comprises arch-shaped runners 33 mounted on a U-shaped frame 35 strengthened by a web 36. The lower end of the arm 12 is connected via a pivot 43 to the end 42 of a link 40 of a spring-over mechanism 38 which ensures that the arm is normally set in one of the two positions shown in dotted outline in Fig. 1. The other end 44 of link 40 is pivoted to a shorter link 41 pivoted to a vertically movable plate 47 urged downwardly by springs 51. Each bale 2 is held momentarily on the arm edge 13 by two flaps 15, 16 which are opened by the subsequent bale acting on a trip mechanism (17), Figs. 2, 5 (not shown) comprising a trigger (18) and linkage (19, 20, 21). The first bale, e.g. 1, entering the trailer 1 slides down the runners 33 either to the left or to the right depending on the arm position, strikes an appropriate outer partition 60 and tumbles down between the partition and the relevant trailer wall, e.g. 10. Bales 2 and 3 stack on to bale 1, but bale 4 strikes bale 3, deflects the arm 12 which is subsequently urged over-centre to the other dotted position and enters between the outer partition and a central partition. Bales 5-7 enter the other outer subdivision of the trailer and bale 8 enters the other inner sub-division as in the manner of bale 4. Bale 9 enters the first inner sub-division and bale 10 enters the other sub-division thereby trapping the lower section 31 of the arm 12 in the full line position shown in Fig. 1. Bale 11 enters either of the inner sub-divisions depending on the terrain and acts on the appropriate plate 37 so that bale 12 is directed into the other inner sub-division. Bales 13 and 14 may be added and are stacked randomly. The trailer deck 55 is tipped by a hand-operated tripping mechanism (65), Fig. 6 (not shown) comprising a spring-loaded, angled lever (66) having a pull-cord at its upper end and a U-shaped deck-mounted hoop straddling its lower end.

Title: Track signalling apparatus
IPC: B61L25/02
Filed: 1971-07-21
Abstract: 1412243 Determining train position ERNEST F MOY Ltd 18 Aug 1972 [21 July 1971]  34256/71 Heading B7N Apparatus for determining the position of a train on an electrically continuous track comprises an arrangement for applying a signal to the track at each of a series of locations in sequence receive elements at the locations for measuring the received signal at locations adjacent to the location to which the signal is applied and a comparator for comparing the received signals with stored signals having values which would be received at the locations in the absence of a train. The apparatus at the locations is controlled from a central office which is connected to the locations by address cores, data lines and a power cable. The locations are addressed in sequence from the central office and on receipt of its address a decoder D1 at a location issues signals to bias on FET's 1 and 2 whereby the output of oscillator 01 is applied via operational power amplifier OA1 and tuned transformer T1 to the rails of the track. At the end of the transmit period at a given location the address of the next location is sent and this when received at the given location is read by decoder D2 which acts to restore FETs 1 and 2 to their non- conducting state and also biases on FET 3 whereby the amplifier OA1 acts to maintain the transformer current at zero so the circuit as seen from the rails presents a high impedance. During the time a location transmits to the rails the voltages received at, e.g. four locations to each side of the transmitting location are transmitted in turn to the central station. The voltage is obtained from the primary winding of the transformer T1 and applied via a rectifying circuit and an A/D converter to a series of gates G1-G5 which are biased on when a further address signal from the central office is read by decoder D 3 . The digital representation of the voltage is then applied via line drivers LD1-LD5 and the data lines to the central station.

Filed: 1930-11-15
Abstract: <PICT:0357417/IV/1> In dye-jigs of the type described in Specification 333,366, [Class 15 (i), Dyeing &c., Apparatus for], wherein two batch rollers B, B1 in contact with a driving bowl A are mounted in slotted arms D which are reversible about a centre O, the arms at each side of the apparatus being connected together by suitable gearing to cause them to move in unison, instead of two expander bars mounted on reversing arms to engage the cloth as it leaves the dye-bath, a single curved expander bar X1 is provided which contacts with the fabric in one position or the other as the batch rollers are reversed.  In the form shown, this is effected by providing the driving bowl A at each end with a half wheel E engaging through an intermediate pinion F2 with a pinion F1 carried by a shaft F, on which arms X carrying the curved bar X1 are mounted.  When the batch rollers B, B1 are reversed by turning them about the axis O, the bar X1 is turned about the shaft F through an angle of over 180 DEG  into its new position.  Other forms of gearing, such as a chain and chain wheels, may be used which cause the bar X1 to turn through the necessary angle without turning on its own axis.
