Title: Control system for trucks
Inventor: MORRIS HERBERT
IPC: B60L15/04
Filed: 1961-01-10
Abstract: 922,659. Control of several D.C. motors. ELECTRO-HYDRAULICS Ltd. Dec. 20, 1961 [Jan. 10, 1961], No. 1081/61. Class 38 (3). An industrial truck has a  divided battery I, 2, adapted for series or parallel connection, a traction motor 8, and auxiliary pump motors 13, 14, for tilting and lifting respectively. Initially, when the truck is stationary, the battery sections 1, 2 are connected in parallel. Closure of contacts 19 to select lifting energizes motor 14 and connects the sections 1, 2 in series, a resistor 17 providing smooth switching transition. A circuit is also completed for the pump motor 13. If switch 19 is returned to neutral and switch 21 is actuated, both pumps are driven at half-speed since the battery sections are connected in parallel. When the truck is driven slowly in either the forward or reverse direction, contacts 25 or 28 are open so that the battery sections are connected in parallel, and only half the maximum voltage can be applied to the pump motors. To drive the truck at full speed, contacts 32 are opened and contacts 31 are closed, whereby the battery sections are connected in series. Energization of pump motor 13 is prevented, but pump motor 14 may be operated by means of switch 19 or 22. In another arrangement an additional switch is provided to connect the battery sections in series when the truck is stationary and tilt is selected, the lift selector being in neutral when tilt is selected under these conditions. If lift and tilt are selected when the truck is stationary, both pump motors are driven but the battery sections are connected in parallel, Fig. 3 (not shown). In a further embodiment, a rectifier is included in the control circuit. When the truck is stationary and lift is selected, maximum voltage is applied to both pump motors; if tilt is selected and the lift selector is in neutral, the motor 13 is energized but the motor 14 does not run because the rectifier prevents energization of coil 37. If tilt and lift are selected simultaneously, both pump motors are driven and the battery sections are connected in series. When the truck is driven slowly and lift or tilt is selected, both pump motors are driven and the battery sections are connected in parallel. When the truck is driven fast and lift is selected the battery sections are connected in series and the motor 14 is energized. If tilt is selected, the motor 13 is not energized, Fig. 4 (not shown). The pump motors are prevented from starting simultaneously, thus reducing the peak load on the battery. The field windings of the motors may be tapped through electromagneticallyoperated contacts.

Abstract: 544,523. Annealing and decarburising iron. COLD METAL PROCESS CO. Jan. 27, 1941, No. 1084. Convention date, Jan. 19, 1940. Drawings to Specification. [Class 72] [Also in Group XXII] Sheet steel such as tin plate is manufactured from a coil of hot rolled strip, of carbon content 0.15 to 0.30 per cent. and from 65 to 109 mils thickness, by passing it to and fro in a cold rolling mill to reduce the thickness to about 10 mils. The cold rolled sheet is passed through a furnace with a reducing atmosphere in which it is heated, at least momentarily to about 1700‹ F., followed by passage through a cooling chamber to a coiler which may supply the tractive effort. The strip may be further cold rolled as described in Specification 489,578 and is then tinned either in strip form or after being cut into sheets. The treatment causes the surface layers to become substantially pure ferrite and the product is said to have great ductility and to be particularly suitable for use in the production of food containers and beer can ends.

Abstract: 1,261,821. Control of A.C. motors. DANFOSS A.S. 23 Jan., 1969 [23 Jan., 1968], No. 1558/69. Heading H2J. [Also in Division G3]  A direct-current source is connected to a semi-conductor switch 4 associated with a filter 5 to produce a regulated voltage Ur which is applied to an inverter 9 for feeding a threephase motor 10. Control equipment for the switch 4 comprises a monostable multivibrator 13 which is connected to a pulse-width controller 14 and to a frequency controller 15. A switch 16 enables the pulse-width to be reduced to a predetermined value, whereupon the frequency is reduced. The switch 16 is operated by a discriminator 17 which compares the voltage Ur with a reference voltage applied to terminal 18. The current through resistor Rl is detected by switch 19 which is connected to the switch 16 either directly or through the discriminator 17 to limit the load current. The discriminator 17 also receives a signal representing the slip of the motor 10, and a process control signal. The switch 4 is constituted by a controlled rectifier which is associated with a capacitor adapted to be charged through diodes until a further rectifier receives a quenching impulse. The capacitor then discharges through a choke and gains a reverse charge to quench both rectifiers, Fig. 3 (not shown). The frequency controller 15 comprises a unijunction relaxation oscillator having a capacitor in series with a transistor whose base is connected through a Zener diode to the switch 16. The multivibrator 13 comprises two transistors coupled through a capacity for determining the pulse-width. The multivibrator controls a further transistor in series with the primary winding of a transformer having two secondary windings for supplying the respective firing and quenching pulses to the switch 4. The switch 16 comprises a transistor for controlling the rate of charge of the capacitor which determines the pulse-width. When this transistor becomes more conductive, the pulse-width is reduced as well as the frequency of the controller 15. The discriminator 17 is connected through intercoupled transistors to the switch 16. A further pair of transistors receives the currentsignal which exerts an over-riding control to block the output of the discriminator and reduce the pulse-width and frequency when a limiting value is exceeded, Figs. 4, 5 (not shown).
