Title: An arrangement for successively applying the brakes of a trailer and of a tractor to which the trailer is attached
IPC: B60T13/58
Filed: 1968-02-16
Abstract: 1,205,702. Tractor/trailer braking system. REGIE NATIONAL DES USINES RENAULT. 16 Feb., 1968 [23 March, 1967], No. 7627/68. Headings F2E and F2F. In a tractor/trailer braking system having mechanical control for the tractor and hydraulic control for the trailer brakes, the application of the tractor brakes is caused to lag that of the trailer brakes. As shown, a brake pedal 1 and the tractor brake control rod 7 are both fulcrumed on a movable lever 3 which in turn is fulcrumed on a stationary pivot 4. When the pedal 1 is depressed it firstly pivots on a pin 2 and the pedal heel 9 engages a push member 10 of an hydraulic valve 11 to close an exhaust outlet 13 leading to a reservoir. This causes hydraulic pressure communicated via an inlet 12 from an hydraulic distributer on the tractor to increase in the valve 11 and apply the trailer brakes via an outlet 14. Continued effort on the pedal as it bears against the depressed push member 10 causes pin 2 to move to the right rotating lever 3 about pivot 4 thereby pulling rod 7 to apply the tractor brakes.

Title: Improvements in or relating to toothed gearing
Filed: 1922-03-16
Abstract: 194,152. Carling, W. T. March 16,1922. Clutches; differential gearing; variable-speed gearing. - In variablespeed or differential gearing, one or more sets of compound epicyclic gears are employed in each of which two sun-wheels on the same shaft are connected by planetary trains, irreversible mechanism, such as worm gear, being arranged between the two sun-wheels, the arrangement being such that the driving pressure locks the gear. In effect, the arrangement comprises a one-way driving device or ratchet clutch which depends for its action upon the locking of worm teeth. The application to differential gearing is shown in Figs. 9, 10, and 11. A frame 12 carries two of the devices each driving a separate part-axle 2. Each device comprises a spur pair 13, 8 and a train consisting of a bevel pair 15, 16, a worm 18 and a worm-wheel 3. The wheels 8, 3 are mounted on the shaft 2 with different amounts of back-lash so that when the casing 12 drives, the worm 18 jams, but when the shaft 2 drives, the worm gearing works loosely. An automatic two-speed gear is shown in Figs. 1 and 5. A driving-shaft 1 normally drives a casing 12 solid through a locking train 8, 13, 15, 16, 18, 3, this drive passing to the driven shaft 2. On the load increasing, a spring 7 yields, with the result that this train unlocks and the drive passes through a countershaft 35 and a train 29, 28, 32, 33, 26, 25, which now becomes locked.

Title: Improvements in electrical apparatus and systems for controlling electric current generators
IPC: H02J7/22
Filed: 1929-03-11
Abstract: 307,796. Eclipse Machine Co., (Assignees of Lansing, R. P.). March 13, 1928, [Convention date]. Supplying consuming devices from variable-speed generators; regulation, automatic. -Apparatus for controlling the output of a variable speed generator comprises an electromagnetic switch 41 for connecting the generator in parallel with a battery and consumption circuit at a given voltage, and two vibratory regulators 40 controlling a resistance in the field circuit of the generator. One of the regulators is operated by the dynamo voltage and the other by a portion of the field current. The switch and regulators are similar in construction and comprise an L-shaped member such as 43 fixed to a base-plate and carrying the core 42 and an armature balanced on its pivot 45. A spring 49 controls the armature and may be adjusted bv a serrated member 54 coacting with a latch. The regulator has an adjustable fixed' contact on a screw 51; the main switch has a fixed contact 64. The single winding of the regulator is connected across the terminals of the dynamo armature and its contacts are in parallel with a resistance 69 and in series with the field winding. The main switch has two windings, a shunt winding connected between the dynamo armature terminals through the second, series, winding in the open position of the switch; the junction of these windings is connected to the switch armature 61, which engages its fixed contact and is directlv connected to a battery terminal when the dynamo voltage is suitable. The current output of the dynamo on overload is controlled by an additional regulator with a single thick-wire winding 82 in series with its own contacts and the contacts 50, 51 of the regulator 40 and operating upon the same resistance 69. The fall of voltage induced at the generator terminals by the over. load puts the regulator out of action, but the resulting increase in field current sets the contacts controlling by the winding 82 vibrating, and the current output is controlled thereby.

Title: Cooling and Receiving Apparatus for Compressed Gas.
Inventor: RUSSELL CHARLES MICHAEL BUCHAN
IPC: F28D7/10
Filed: 1966-02-24
Abstract: 1,169,515. Gas cooling installations. C. M. B. RUSSELL. 3 March, 1967 [24 Feb., 1966], No. 8083/66. Heading F4S. Cooling apparatus for moist compressed air comprises a vessel 10 containing one or more heat exchangers in which the air is cooled and then reheated to a temperature below that of the inflowing air, said vessel having an inlet 23 and an outlet 24 for the compressed air, and means such as a valve 13 for drawing off the liquid condensed from the air. As shown, the apparatus includes two heat exchangers 14a, 14b, each said heat exchanger comprises a central, finned, vertical tube 17 connected to a coolant-water supply pipe 15, said tube containing a field tube assembly (not indicated) and being surrounded by three coaxial tubes or sheaths 18, 21, 22, so that in operation, compressed air entering via the inlet 23 passes either to the first heat exchanger or through a connecting tube 26 to the second heat exchanger. In both eases the hot air ascends through the space between the outer tube 22 and the intermediate tube 21 and then descends between the finned tube 17 and the associated sheath 18. During such downward passage the hot air is cooled, the water vapour which condenses out draining to the base of the vessel 10 where it can be drawn off through the valve 13. The cooled air then passes upwardly between the relatively cool outer surface of the sheath 18 and the relatively hot inner surface of the intermediate tubes 21 thus reheating the air before it reaches the outlet 24, and lowering the relative humidity of the air discharged from the vessel 10, whereby regardless of the ambient temperature surrounding an air line connected to the outlet 24, the temperature of the air in said air line will not fall to a value such that condensation in the air line will occur.
