Abstract: The prefabricated flat lid part, prepared for being set up, for a package for chocolates in the form of a folding box has a lid panel, projecting evenly on all sides in relation to the package body, for formation of a double-layered projecting edge. The lid part consists of a single blank and the side walls are formed in each case by two side wall parts and the inside side wall parts of the longer side walls of the lid part are slightly wider, preferably by about 0.8 mm to 1.2 mm, than the outside side wall parts. The longer side walls parts are folded inwards over the fold bounding the lid panel, then outwards over the adjacent parallel fold and finally inwards over the fold between the two side wall parts and the outer bounding tabs, adjoining the inner side wall parts, are glued to the inside of the lid panel. The shorter side parts are folded inwards over the fold adjoining the lid panel and glued to the inside of the lid panel by the edge strip adjoining the lid panel.

Abstract: A driving apparatus for negative-impedance driving a speaker as a load, comprises a detection element, a positive feedback circuit, a temperature compensation circuit, a sensor element, a control circuit, and an input f characteristic control circuit. The resistor as the detection element connected in series with the load detects a current flowing through the load. The feedback circuit feeds back a detection output of the detection element to an input side of the driving apparatus. The temperature compensation circuit controls the negative-impedance driving state to compensate for an increase in load impedance upon an increase in temperature of the load. The sensor element detects that a temperature of the load reaches a predetermined value. The control circuit stops temperature compensation of the temperature compensation circuit or decreases a degree of temperature compensation in accordance with an output from the sensor element. The input f characteristic control circuit controls frequency characteristic of an input signal in accordance with an output from the control circuit.

Abstract: In an optical switching network, a master optical space switch (100) is interconnected with remote slave equipments (110,120) for switching block-multiplexed messages among the remote equipments. The master optical space switch responds to a frequency reference clock (31) and steps through a sequence of states, or configurations, for establishing various routes among the remote equipments for appropriately routing the messages to correct destinations. The frequency reference clock also is distributed to the remote equipments. During one of the states per frame, each remote slave equipment transmits a distinct signature signal. All of the slave equipments are connected through the master optical space switch to return to themselves their own signals transmitted during that time slot. Each remote slave equipment compares the returned signal with the originally transmitted signature signal to determine how much the round trip delay has varied from a nominal value. Phase of a local control clock (125,155) signal in the slave equipment is adjusted to counteract the variation of the round trip delay. Thus the operation of the slave equipment is adjusted into synchronization with the master optical space switch so that messages transmitted from the slave equipment arrive at the master optical space switch at the appropriate time with respect to the periodic reconfigurations of the master optical space switch.

IPC: H02M5/458
Filed: 1989-12-28
Abstract: A method of regulating the output voltage of an electric power source combines a status signal representa­tive of the output voltage of the power source with a reference signal to produce a first control signal. A status signal representative of the output current of the power source is combined with the reference signal to produce a second control signal. A bias voltage signal is applied to a junction point 100 and the first and second control signals are connected through an OR network CR19, CR20, CR21 to the junction point, thereby forming an output signal at the junction point. The power source output is then controlled in response to this output signal. Under normal operating conditions, the magnitude of the control signal corresponding to the power source output voltage is less than the magnitude of the bias voltage signal, and the magnitude of the control signal representative of current is greater than the magnitude of the bias voltage signal, such that the voltage sensing loop is in control of the power source output.

Abstract: A dynamoelectric machine in the form of an induction motor (14) includes a rotor assembly (30) and a stator assembly (32) mounted between front and rear, cast alumi­num endshields (36, 38). The endshields (36, 38)have axi­al and radial apertures (42, 44) formed in them to assist in motor cooling in the space-limited application envi­ronment of a clothes washing machine, for example. A mo­tor shaft (20) extends through a journaled bearing (60) in a bearing housing (58) projecting from the front end­shield (36). A mounting plate (18) is provided for moun­ting the motor (14) in applicational use. The shaft (20) extends vertically downward through the mounting plate (14), to which the transmission (16) of the washing ma­chine also is mounted, so that a transmission shaft (26) also extends through the mounting plate (18). A drive pulley (22) is attached to the motor shaft (20) and a driven pulley (24) is attached to the transmission shaft (26). The pulleys (22, 24) are maintained in planar alig­nment to permit belt transfer of power between the two and to minimize belt wear once the motor (14) has been secured to the mounting plate (18) by means of mounting ears (50) which form a part of the front endshield (36) of the motor (14). The rear endshield (38) has an inter­nal bearing housing (54) which provides a flush endshield surface (39 B) facing upwards towards the bottom of the machine wash tub (12). Because the front endshield (36) mounts the motor(14), motor size, i.e. motor height can be varied to address differing machine load capacities by increasing the motor physical size, i.e. stator assembly stack height, between the fixed-position front endshield (36) and the rear endshield (38) to the extent permitted by the overall space available between the flush surface rear endshield (38) and the flat bottom of the wash tub (12).

Abstract: This invention refers to a solution for an intermediate exchanger (100) for fast reactors, with a tube bundle (101) of straight tubes, primary sodium outside the tubes, a raised upper plate (6), a suction siphon (8), and equipped with a second intermediate input window (9) for emergency access of the primary sodium into the exchanger in the event of failure of the feed system through the upper window (6). 
     According to the invention, said emergency input window (9) is created by a suitable number of holes in the outer ring (10) of the exchanger (100), and is positioned at a suitable height to guarantee hydraulic connection between the hot (1) and cold headers (2) under any circumstances. 
     According to a preferred embodiment of the invention, and in order to prevent an excessive share of the primary flow from entering through the emergency window rather than through the nominal input window, thus reducing the effective heat exchange length to the detriment of the thermal power achievable, an extension (12)   of the siphon as far as the emergency window is envisaged, shaping the siphon in a suitable manner.
