Title: Electric distant transmission of angular positions
IPC: G08C19/38
Filed: 1929-09-30
Abstract: 340,561. Distant control systems. COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT, 12, Rue de la Rochefoucauld, and GRANAT, E., 10, Rue Caumartin, both in Paris. Sept. 30, 1929, No. 29537. Convention date, Nov. 6, 1928. [Class 40 (i).] In a system for transmitting angular movements of the type wherein brushes co-operate with a distributor to vary the distribution of current in the windings of a polyphase receiver motor, two or more supply wires of different potentials are connected to a predetermined number of segments of the distributor in such a manner that relative rotation of the distributor and brushes causes corresponding rotation of the receiver, the possible number of angular positions depending upon the number of phases in the receiver and the number of different potentials at the transmitter. As shown in Fig. 1, a distributor 1 has two series of segments connected in a predetermined manner to the slip rings 3, 4 of a d.c. supply 2. Fixed brushes 5 .. 9 are connected to the separate phases 12 .. 16 of the receiver, the rotor 17 of which is supplied from the mains 2. Rotation of the distributor causes variable distribution of current in the phases 12 .. 16, the arrangement being such that current may be made to flowin one or other direction-in any two or more of the phases. In the modification shown in Fig. 3, two sets of brushes 21, 22, 23 ; 24, 25, 26 and two sets of receiver windings 30, 31, 32 ; 33, 34, 35 are utilized in order to increase the possible number of receiver positions. As shown both sets are relatively displaced by an equal angle although the angles may differ. In a further modification, the number of receiver positions may be increased further by providing a plurality of sets of windings 36, 37 angularly disposed and arranged to be switched in separately or in combinations by a switch actuated simultaneously with the distributor. The d.c. supply 2 may be replaced by a single-phase or three-phase alternating current supply. In the Specification as open to inspection under Sect. 91 (3) (a), Specification 216,155 is referred to. This reference does not appear in the Specification as accepted.

A concrete or like mixer comprises a self-propelled dirigible wheeled chassis 2, 3, 4, Fig. 2, carrying a rotary mixer drum 7, Fig. 3, and a skip 16 for loading the drum, means e.g. a clutch 32 having a control lever 31, connecting the power unit (under a bonnet 1) of the chassis to the drum, means 10, 12 for tilting the drum for loading or unloading and means 17, 18, 19 and 20 for positioning the skips in! a position to scoopup material to be mixed or a position for discharging the material into the drum. The front wheels 21 are driven from the power unit via a clutch and change speed gear (not shown) a shaft 39, differential 38, axle shafts 35, sprockets 34 and chains 33, the wheels 21 being carried by stub axles fixed to side plates 2a at the ends of the front beam 2. The rear wheels 22 are steerable on the rear axle bar 4 pivotably conected at 4a to a wide V-shapped frame' secured to the main chassis tubes 3 which are secured to front beam 2. The power unit can rotate the drum 7 through the clutch 32, reduction gear 30 and a shaft 13 provided at its ends with universal joints 41, 42. The joint 41 is connected to a spigot 40 within a drum recess 43. The drum 7 is provided with a channelled ring 7a engageable by rollers 8a carried in a ring frame 8 having trunnions received in bearings 9 secured to the upper ends of a pair of arms 9a pivoted at 9b to the side plates 2a. The arms 9a are pivotably connected at 15a to the ends of a V-shaped yoke 15 having an apical plunger 15b engaging a tube 14 of a stabilizer. Secured to the trunnions at each side are cranks 12 one of which is secured to a manually operable lever 10. The cranks 12 are engageable with stops 11 on the plates 2a to determine the loading position of the drum as shown in Fig. 3, and its unloading position. The arrangement of the pivoted arms 9a renders the use of a telescopic shaft 13 unnecessary. The lever 10 is retainable by a hook 10a. The skip 16 is secured to a U-shaped frame 17 having cranked portions secured to a shaft 18 rotatable in bearings 36 Fig. 2, carried by brackets 37 on the frame tubes 3. Secured to the shaft 18 is a lever 19 conected to the piston rod 20b of a piston movable in a hydraulic cylinder 20 under the control of a reversing valve 27 connected to the cylinder and a pump driven from the power-unit by piping 27a. The cylinder 20 is pivoted at 20a to an anchorage. The valve 27 is arranged so that the skip can be raised beyond the position shown in Fig. 3 and below the scooping position in line with the wheel base. In the latter case the skip may be used to jack-up the front wheels out of soft ground. The valve may be operated to shake the skip to loosen material adhering thereto. All of the controls are readily assembled from the driver's seat 29.

Abstract: 425,631. Road - surface heaters. JOHNSTON, J. T. M., and HOBBS, J. E., 35, Crutched Friars, London. Nov. 1, 1933, No. 30392. [Class 107] Relates to road-surface heating machines of the kind in which heated gases are directed over the road surface by a hood 23. According to the invention, the gases are supplied to the hood by a downwardly directed conduit 25, which is mounted on a turntable 14 on a vehicle 10. In the construction shown, the turntable is mounted by rollers 13 on an annular track 12 and carries a part-circular toothed rack 16 meshing with a pinion 17 which is rotated by a handle 21. The hood and conduit are carried respectively by arms 22 and brackets 24 mounted on the turntable. The turntable carries also a motor 26 and a blower 27 driven thereby, the blower supplying air to the conduit 25 through a pipe 28. The air supplied is heated by an oil burner 29 associated with a combustion chamber in the conduit, and gravity fed from a fuel tank 31 mounted on the turntable. Alternatively, the air may be heated by an electrical heater mounted in the conduit or in the hood. The wheels of the vehicle are protected from the heat of the hood by a screen 32. In a modification, the means for supplying air and fuel to the heating device are mounted on a fixed part of the vehicle. In this case, the king pin 15 of the turntable is made hollow for receiving the necessary feed pipes. In another modification, the turntable is mounted on a trailerchassis, and the rack is completely circular so that the hood can be adjusted to positions on all sides of the vehicle.
