Title: Electric railway signal repeating system
IPC: B61L3/20
Filed: 1922-03-01
Abstract: 176,368. Bethenod, J. March 1, 1922. Track apparatus actuating signals on trains. - A signalling relay or repeater on the train is supplied from the same source as the traction motors and is controlled by a switch operated by the track signal. In the arrangement shown in Fig. 1, the car 1 carries collectors 2, 2<1>, one of which makes contact with the line wire 3 to supply current to the traction motors. A second pair of collectors 5, 5<1> are connected through the coil of the repeating relay 4; one of the collectors is in contact with the line 3 while the other makes contact with a short insulated rail 6 on the track. A switch 9 controlled bv the signal arm is connected between the rail 6 and an earthed resistance 8. The relay 4 remains de- .energized unless the switch 9 is closed when the car travels over the rail 6, in which case the relay operates and the signal is repeated on the train. The resistance 8 prevents the traction circuit from being short-circuited when the - collectors pass over the rail 6. In the modification shown in Fig. 2, the relay 4 is normally energized as it is connected between the line 3 and an earth 7 on the train. Gaps are left in the line 3 and opposite each gap is placed an insulated rail 6 slightly longer than the gap. The switch 9, when closed, connects the rail 6 to a line wire 10 supplied similarly to the line wire 3. The relay only operates when the collectors are on the rail 6 and the signal operated switch 9 is open. The rail 6 may be placed in the gap in the line 3 and to ensure proper connections at crossings &c., several pairs of signalling collectors may be provided on the car.

Title: Improvements in and relating to lowering mechanism
Inventor: HALL FREDERICK JOHN
IPC: B65G47/57
Filed: 1953-03-05
Abstract: 736,244. Load-handling machines; balancing apparatus; roller conveyers. BRITISH MATHEWS, Ltd. May 28, 1954 [March 5, 1953], No. 6129/53. Classes 78 (1), 78 (2) and 78 (3). In counterbalanced platform apparatus for lowering goods of the kind which remains at the upper station until it is loaded, then automatically descends to the lower station where it is unloaded and then returns automatically to the upper station, means is provided for loading the platform with more than one article in succession and preventing its descent until the required number of articles have been placed on it even though the weight of a single article is sufficient to overcome the counterbalance. The platform 1 is held in the upper position by the engagement of catches 11, 12 pivoted on it with a stationary cross-bar 13, Fig. 2. , The catches are connected by rods 17 to the depending arms 16 of bell-crank levers 11a, 12a pivoted to the platform. The upper arms of these levers are engaged by the articles 10 as they pass on to the platform and are depressed to disengage the catches. As the first article passes on to the platform, it effects the release of the catch 11, but the catch 12 remains in engagement. When the article clears the lever 11a, the catch 11 re-engages and holds the platform when the catch 12 is released by the depression of the lever 12a. The entrance of the second article causes the release of the catch 11 and the platform descends. The passage of articles from the roller conveyer 7, except when the platform is in alignment with it, is prevented by a cross-bar 9 carried by pivoted arms 30. This bar is raised by an abutment 32 carried by the platform. The articles are retained on the platform by the horizontal part 20 of a stop member which normally is kept in obstructing position by springs. The vertical members of the stop are connected to pivoted members 22 which, on striking an abutment 25 at the end of the descent, are rotated clockwise to withdraw the stop. The inclined platform 1 is connected to two two-piece guide members 4 which run on tubular columns 2 containing the balance weights. These weights act as pistons and are connected to the platform by cables passed over idler pulleys 3. The air compressed by the movement of the weights escapes through valve-controlled vents 6 and checks the movement of the platform.

Abstract: 1363568 Unpackaging and re-packaging articles; conveying fruit in liquid containing channels; hoists SICA "POMANJOU" 15 Feb 1972 [16 Feb 1971] 6869/72 Headings B8C B8A and B8H Apparatus for handling buoyant products comprises a vessel having a dual function of emptying cases containing the products and filling them, a liquid emptying circuit and a liquid filling circuit selectively connectible to the vessel and handling means operable to immerse a case into the vessel and remove the case from the vessel after discharging the initial contents and refilling the case with other products. As shown in Fig. 1, cases 3 of fruit arranged in stacks in a storage area G are moved one at a time by a handling means F at each of two emptying and filling station A and lowered into a vessel 2 which contains water whereby the fruit is removed from the case by the buoyancy of the fruit and is carried by the water to a transfer trough B from which it is picked up by a conveyer 14 and directed to a sorting and grading station C from which it is returned to the vessel 2 along water filled troughs D and re-introduced into the case 3 according to grade and/or weight. The case 3 is then removed from the vessel 2 by the handling means F. The latter includes within a framework 45, Fig. 6, a pair of motor driven slides 49 each of which carries an arm 54 which is engageable with an aperture 56 on the base of the case 3, whereby the case may be lifted off its stack and lowered into and removed from the vessel 2. As a filled case is lowered to the position shown in Fig. 8, the output of a pump 4 is directed to a discharge port 10 and a gate 13 between the vessel 2 and the trough B is opened to direct the fruit in a stream of water into the trough B. Subsequently the pump output is directed to a port 12 and the gate 13 is closed whereby the fruit is directed towards the conveyer 14 and the station C. The empty case is then lowered to the bottom of the vessel 2 and a hopper 64 is lowered over the case, Fig. 9, and the suction side of a pump 19 to a port 26 and a gate 32 in a collecting trough E is opened to cause fruit from the station C to pass into the hopper 64 above the case 3. The gate 32 is then closed, the suction side of pump 19 is connected to port 27 and the case 3 and hopper 64 are lifted from the vessel 2 whereby water drains from the case and hopper and the graded fruit is distributed in the case 3. The hopper is then raised to the Fig. 7 position and the handling means operated to move the case to a storage position where it is released from the arms 54. At the grading station C, fruit from the conveyer 14 is delivered to an inspection table 15 from which it is directed to an eight line, six-gauge grading machine, the graded fruit discharging into the underlying troughs D. A conveyer 18 above the table 15 is provided for disposal of spoiled fruit, which is discharged to a conveyer 33 and hence into a discharge branch 34 of a trough D.
