Abstract: ] In a motor vehicle rear suspension a screwjack is inserted between each wheel and the vehicle frame, and reversible electric motors 11, 1 1 associated with each jack respectively, and each controlled by an attitude-sensing switch, Fig. 3, which adjust the lengths of the jacks. The switch comprises a part 31 fixed to the vehicle frame and carrying contacts 18, 19, and a pair of flexible contact plates 32, 33 carrying contacts 211, 2111. A magnet 34 which senses the attitude of the vehicle is movable to attract either plate 32 or 33 to close one pair of the contacts. In the circuit, Fig. 1, a switch 23 is closable manually or by opening a vehicle door or the boot lid to energize the switches associated with each jack. Referring only to one switch and its associated circuit, if either pair of contacts closes a circuit is completed through a limit switch 16 or 17 and a relay 14 or 15. The relay will trip its contact 141 or 151 to energize the motor. In modified circuits, resistors and diodes are used in holding circuits to allow the required suspension set-up to be obtained if switch 23 is opened too early. Alternatively switch 23 may comprise a time-switch.

Patent ES-370944-A1 (ES)
Title: Weld current controller
IPC: G05D3/14
Filed: 1969-08-28
Abstract: Apparatus for arc welding two edges of strip material together comprises a servomotor and amplifier controlled by signals developed in the welding circuit such that the standing, starting and running values of the weld current are controlled according to the type and thickness of the strip material being used. A resistance potentiometer 3, the slide of which is driven by a servomotor 2, is connected in the welding circuit to control the welding current and the physical characteristics of this potentiometer are individually designed to suit the strip material being welded. Before an arc is struck relay SR/1 and the relay controlling contacts RR/1 RR/2 are de-energized. A servo-amplifier 1 then receives a signal from a bias circuit B2 and the servomotor 2 operates to drive the slider of potentiometer 3 to the "low current" end. An arc is then struck by switching on the welding current source together with a high frequency starting circuit. When an arc is struck a photo-cell 4 sensitive to the presence of the arc causes energization of relay SR/1 which changes over contacts SR/1 so that the amplifier 1 now receives an input signal from a bias circuit B1 in opposition to that received from circuit B2 together with a voltage dependent upon the arc current which is developed across a resistor R17. The servomotor 2 then runs to position the slider of the potentiometer 3 until the input to the amplifier 1 becomes zero, velocity feedback being derived from a tachogenerator G. The high frequency starting supply is now switched off. Operation of a push button switch begins the welding process and also energizes a relay coil which operates contacts RR/1 and RR/2. Closure of RR/2 alters the bias supplied to the amplifier 1 from the circuit B1 whereupon the motor 2 drives the slider of the potentiometer 3 to a position to give the correct welding current value, the contacts RR/1 being optional so as to provide a large increase in the value of the welding current if desired. A tachogenerator 6 dependent on the speed of the welding operation provides a signal to make the welding current dependent on that speed and if desired a function generator 7 may be incorporated to provide any desired welding current function. When stopping the welding process the opposite sequence of events takes place.

Title: Device for packing objects in a bag
IPC: B65B67/12
Filed: 1972-09-06
Abstract: The invention provides an improved device for packing objects in a bag, in which the objects are pushed through a sleeve to come into a bag that is suspended below said sleeve.

Title: Level sensitive logic system
IPC: G06F11/273
Filed: 1973-10-11
Abstract: A generalized and modular logic system for all arithmetic/logical units of a digital computer. Each arithmetic/logical unit of a computer is partitioned into sections formed of combinational logic networks and storage circuitry. The storage circuitry is sequential in operation and employs clocked dc latches. Two or more synchronous, non-overlapping, independent system clock trains are used to control the latches. A single-sided delay dependency is imparted to the system. The feedback connections from the respective latch circuitry are made through combinational logic to other latch circuitry that has a system clock other than the system clock acting on the initiating latch circuitry. With each latch, there is provided additional circuitry so that each latch acts as one position of a shift register having input/output and shift controls that are independent of the system clocks and the system inputs/outputs. All of the shift register latches are coupled together into a single shift register.
