Title: Manually operated voltage divider with no sliding contacts - depends on finger contact between divider elements
IPC: H01C10/00
Filed: 1975-04-18
Abstract: Typically the resistive element is graded to produce a voltage drip between its ends. A conducting element for example a flexible strip, is located near the resistor in a suitable housing, and takes on the function of the slider. By pressing down at the required point any voltage within the designed range may be selected. Typically this voltage is passed to a voltage storage circuit and, via active circuit elements, for example operational amplifiers, the voltage may be used for control purposes. In an alternative design the operator's finger may be used as the galvanic connection between the resistor and collector of the voltage divider.

Patent NL-8500154-A (NL)
Inventor: AKKER JOUW VAN DEN
IPC: H02M3/338
Filed: 1985-01-22
Abstract: For energizing a load (10) with different input voltages, the circuit comprises a transformer (6), whose primary winding (n1), in series with the collector-emitter path of a switching transistor (T1), the load (10), and a current sensing resistor (R2), is arranged between the input-voltage terminals. The seccondary winding (n2), in series with a diode (D1), is arranged in parallel with the load (10). When the input voltage is applied a very small base current is fed to the switching transistor (T1) via the starting resistor (R1), which results in a small current in the primary winding. The resulting voltage rise across the secondary winding (n2) ensures that the switching transistor (T1) is bottomed rapidly via a positive-feedback loop, which comprises the series arrangement of a first resistor (R4), a capacitor (C1) and a second resistor (R5) and which is arranged between that end of the secondary winding (n2) which is connected to the diode (D1) and the base of the switching transistor (T1). For a specific current in the primary winding (n2) the switching transistor (T1) is turned off by means of a control transistor (T2), whose base is connected to the current-sen sing resistor (R2). The energy stored in the transformer (6) is then delivered to the load (10) by an output current in the secondary winding (n2). In order to prevent this output current from increasing strongly at increasing input voltages as a result of the increasing saturation of the switching transistor (T1) via the positive feedback, a zener diode (Z1) is arranged between the junction point of the capacitor (C1) and the resistor (R5) and the base of the switching transistor (T1). Above a specific input voltage this zener diode (Z1) is turned on and drains the base supply current to the emitter of the switching transistor.

Title: Foldable tent
IPC: E04H15/48
Filed: 1993-12-23
Abstract: The invention relates to a foldable tent, in particular a tent comprising a tent canvas and a frame which is formed by gate structures which, in the erected state, extend in a vertical plane and rods which extend substantially perpendicular to the gate structures and are horizontal in the erected state, the gate structures being pivotable within the vertical plane, the gate structures being slidable on the horizontal rods, and the gate structures each being formed by uprights which are pivotably connected to one another in the projecting part and each comprise a hinge. As a result of this measure, the tent can not only be folded up in the first direction, i.e. in the plane of the gate structures, but also can be folded up, or at least pushed together, in a direction which extends perpendicular to the first direction. This means that a tent of larger dimensions, such as a tent which can be used for building work, can also be folded up to form a portable unit. This measure ensures that the tent can be erected or taken down in as short a time as possible.
