Title: Tractor-trailer brake system
IPC: B60T13/58
Filed: 1969-07-15
Abstract: 1281591 Tractor-trailer braking systems BERG MFG & SALES CO 15 July 1969 [15 July 1968] 35657/69 Heading F2F In a tractor-trailer braking system, actuation of an actuator 16 of an application valve 4 on the tractor causes operation of an electrical signal generator 17, the signal from which causes operation of a solenoid modulation valve 35 on the trailer in proportional response to movement of the actuator 16. This ensures that trailer braking occurs prior to or simultaneously with tractor braking. As seen in Figs. 1-4, the tractor has pneumatic cylinders 8 and the trailer has hydraulic cylinders 43 controlled by an airover-hydraulic brake chamber 41 which is connected with the modulation valve 35 via a relay valve 25 and a two-way check valve 31. Tractor and trailer parts of the system are connected by gladhand connectors 10, 10a and 11, 11a and even if the electrical control fails the tractor part may still exert fluid pressure control on the trailer part. The electrical generator may comprise a rheostat or potentiometer although in the embodiment of Fig. 5 (not shown) it takes the form of a servomotor (80) responsive to movement of actuator (16) and electrically connected to a second servomotor (81) for activation of a modulation valve (35a). The modulation valve 35 has an inlet (51) from a reservoir 27 and an outlet (52) connected to one inlet port of the check valve 31 and when the valve 35 is energized a valve mechanism (73) therein is opened to connect the inlet and the outlet and to cause air to pass through the check valve 31 to the relay valve 25 and thence to chamber 41 to give trailer brake application. Conduits 26, 30 leading from connectors 10a, 11a are respectively connected to the relay valve 25 and the second inlet port of the check valve 31 to allow of pressure fluid actuation of the trailer part. The modification of Fig. 6 has a member 85 sensitive to pressure in the tractor engine manifold 86, whereby a signal is sent to the modulation valve 35 when the engine decelerates by removal of the operator's foot from the accelerator to thereby give a braking effect to the trailer, concurrent with the tractor deceleration. The trailer brakes may then be applied if the operator so elects by the actuator 16. It is envisaged that the tractor brakes could be hydraulically operated.

Title: Control of alternating current metadynes
IPC: H02K27/08
Filed: 1954-12-13
Abstract: 756,660. A.C. commutator machines. PESTARINI, J. M. Dec. 13, 1954, No. 36076/54. Class 35. [Also in Group XXXVII] A single-phase metadyne machine is controlled through the phase-angle of its field current. In a transformer metadyne, Fig. 1, fed at its main axis a, c with constant voltage from a single-phase line L, and supplying constant current to loads 15, 16, 17 from auxiliary brushes b, d, the current output is set by the phase-angle of current in control winding 12. This current is derived from a phaseshifting transformer 18 whose stator is fed from the single-phase line through phase-splitting condenser 23 and inductance 24. The speed of the metadyne is regulated by means of current from a synchronously driven alternator 20 which feeds a braking winding 14. The alternator is excited by a generator 27, on the metadyne shaft, and arranged to run at its critical build-up speed. Excess speed causes an increased excitation of the alternator 20 which brakes the metadyne. Modified machines are described in which the loads are connected across brushes a, b, and c, d, or across each adjacent pair. Where the loads consist of dynamo-electric machines, each machine may be individually controlled by a phase-shifting transformer feeding its field winding. A metadyne generator is described having a shortcircuited primary axis, adjustable turn compensating windings to vary the machine characteristic and an exciting winding fed from a D.C. generator whose brushes are rotated to produce excitation current of suitable frequency. The phase of this current is controlled by series-connected variable. condenser resistance and chokes. A self-induced controlwinding is closed through a condenser, resistor and choke. A metadyne motor is described in which the control field winding is fed with current from a phase-shifting transformer excited from a resistance and choke in series with the motor, the quadrature brushes being connected through a compensating winding. In a modification the secondary axis is shorted and control windings on each axis serve to regulate the motor for starting and running by means of phase-shifting transformers which may be connected in series with the motor or separately energized as in Fig. 1. Specification 420,167 and U.S.A. Specifications 1,945,447, 1,969,699, 2,107,740, 2,590,887, 2,599,936, 2,642,556 and 2,662,999 are referred to.

Abstract: 944,465. Film extrusion orifice. E. I. DU PONT DE NEMOURS & CO. Sept. 24, 1962 [Sept. 25, 1961], No. 36206/62. Headings B5A and B5B. An adjustable mechanism for a flat-film extrusion orifice comprises a body member 6 having an adjustable lip 3 slidably fixed thereto, a rigid lever-arm 1 having a cylindrical opening therein fixedly attached to the adjustable lip, a bendable support member 4 fixedly attached to the body member and the lever-arm to form a fulcrum about which the lever arm can pivot, a threaded cylindrical stud 7 projecting from the body member in alignment with the opening, a nut 2 having a skirt provided internally with threads, the nut and skirt being in threaded engagement with the threads of the stud, and resilient means, e.g. a spring 5 between the body member and the lever-arm adapted to maintain a constant contact between the threads of the nut and skirt of the stud. As shown, the body member is preferably U- shaped. Spring 5 may be a coil spring, cantilever spring or may comprise axially mounted frusto-conical disc springs. The mechanisms may employ a lever of the first class, as in Fig. 1, or of the second class as in Fig. 2, the latter being more convenient for increasing the theoretical mechanical advantage in a confined space. In the Fig. 2 apparatus, the support member 4 extends beyond the lip 3 and is attached to the end of the lever arm 1 by cap screw 15. Opening 16 is slightly larger than stud 9 to permit free movement of the stud as the lip is adjusted, and a gap 17 is maintained between lip 3 and support 4 to permit the desired travel of the lip. A number of mechanisms may be arranged along the adjustable lip of the extrusion orifice. In operation the adjusting screw 2 is driven over threads 8 of the stud 7 to move lever arm 1 in the appropriate direction to effect the desired movement of adjustable lip 3. Motion of lever-arm 1 at screw 2 is transmitted as motion of lesser displacement to bendable lip 3 by pivoting of the lever arm around the fulcrum formed by support member 4. Loading spring 5 maintains compressive contact between the lever arm and the threads of stud 7 which is rigidly fixed to body member 6, the upper-portion of which is U-shaped, in order to eliminate backlash and provide immediate positive response at bendable lip 3 to rotation of the screw 2. Lip 3 is slidably affixed to body member 6 by stud 10, elongated channel 11 providing for the opening and closing motion of the lip. Spacer 12 provides for reduced friction and assists in forming a seal between lip 3 and body member 6. The lip is affixed rigidly by stud 9 to lever-arm 1. Coarse adjustment of the lip opening may be made by nuts 13 and 14. The adjustment mechanism is especially intended for automatic control, by, for example, reversible electric motors. U.S.A. Specifications 2,790,945 and 2,829,268 are referred to.
