Abstract: Abstract of the Disclosure A planting device for planting of plants  said device comprising a frame to be mounted on a traction vehicle. A support arm extending backwards in parallel with the direction of movement of the traction vehicle is supported by said frame and is provided with planting displaceable in said direction of movement. The device further includes a plant feeding means displaceable between a delivery point of a plant distribution magazine and said planting means for transferring a plant from said magazine to said planting means. The plant feeding means is displaceable along the same path of movement as the front end of said support arm which supports the planting means. Said path of movement is pivotable around a verti-cal axis passing through said delivery point of said magazine. Thereby  the planting means and the plant feeding means  maintain their mutual position irrespective of the elevational and lateral retrac-ting movements of the planting means.

Abstract: FLOWLINE CONNECTOR SEAL                 ABSTRACT OF THE INVENTION           A flangeless, disc-like seal plate is disclosed for insertion between opposing flowline hubs for sealingly connecting, blocking or rerouting fluid flow between various fluid carrying lines within said flowline hubs.  For connect-ing flow lines, straight throughbores within the seal plate are provided with V-seals in channels on said seal plate around the throughbores, as well as O-ring seals around said V-seals and another O-ring near the periphery of the disc itself.  No seals or seal grooves are necessary on the hub faces. For connecting hydraulic control lines, the seal plate is equipped with transverse channels interconnecting various throughbores but may also be provided with blind ports for totally blocking off certain control lines at the plate.  Within said throughbores, fluid diverter plugs are inserted which are either equipped with protruding caps for opening up corresponding check valves housed within hub lines or flush plugs such that said check valves remain closed after clamp-up. Through this arrangement various lines may either be blocked, be fluidly connected, or have their fluid flow rerouted internally without rearranging the alignment between the lines within the flowline bundle.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved equalizing system for modifying an input electrical signal representative of original sound so as to correct for the inherent nonflat frequency response of an audio signal processing apparatus and the acoustic effects of listening environment in which the loudspeaker system of the audio signal processing apparatus may be disposed.  The improved equalizing system includes comparison means for comparing the signal energy in each of a plurality of select frequency bands of a predetermined frequency range of the input signal with that of the corresponding signal energy in a like plurality of bands of a like range of a second signal representative of the acoustic output of the loudspeaker system and as a function of the nonflat frequency response and the acoustic effects of the environment.  A correction signal representative of the comparison is used to modify the energy within each band of the input signal so as to substantially correct for the nonflat response and the acoustic effects of the environment.  In the preferred embodiment, a unique filter arrangement is provided for simultaneously reducing the interaction between adjacent bands and the amount of ripple at the output of the equalizing system.

Abstract: BOILER FOR USE WITH CHARGES OF WOOD FUEL                 Abstract of the Disclosure A boiler has a chamber to contain a charge of wood that rests on the bottom of the chamber with the major portion of the charge within a water jacketed upper portion of the chamber but free to settle as combustion progresses.  Combustion is confined to the bottom portion of the chamber due to the cooling effect of the water jacket and to a turbulent cross draft in the combustion zone.  A special venturi section in the flue coupled with a pres-sure blower both induces the flow of hot gases from the combustion zone through a second chamber and a heat exchanger and also pro-vides a stream of air from the venturi section to create the cross draft.  An oil burner may be used in conjunction with the second chamber as an alternate heat source.  The boiler also has a special base construction and assembly features.

Abstract: ABSTRACT "COOKING APPARATUS"           An electric cooker or cooking hob has a ceramic plate 2 on which there are a number of hot plate areas each heated by a respective annular heating element 4 disposed within an insulating housing 7.  A temperature dependent resistor 9 is disposed below the hot plate area at the centre of focus of a reflector 8 which is arrange to focus radiant energy from the hot plate area on to the resistor 9 while at the same time shielding the resistor 9 from direct radiation from the electric heating element 4.  The signal derived from the resistor 9 is a measure of the temperature of the hot plate and can be used to provide a thermal tripping function to prevent over-heating of the hot plate area and/or to-carry out closed loop control of the temperature of the hot plate area.  The reflector 8 may be replaced by a shield which shields the resistor 9 from direct heating by the heater.   A further annular heating element surrounding the element 4 may be provided, with the control circuitry enabling either the element 4 alone or element 4 plus the outer element to be energised.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is an apparatus for absorbing and collecting oil or similar substances from the water surface.  The apparatus comprises a floating rope being held in a loop shape and adopted to absorb oil contaminated therewith.  The apparatus is conventionally  provided with a cleaning device removing oil from the rope and with means for pulling the rope past said cleaning device.  In order to improve collection capa-city of the rope, the invention provides means connected to the rope for rotating the same around the longitudinal axis thereof.  Said means can be positioned e.g. at the end of one of two  booms or similar holding the rope in the loop shape.  The cleaning device may be positioned in the middle so that two loops are formed, one on each side of the cleaning device, and the pulling means may then be adopted to pull the rope alternatingly in opposited directions through the cleaning device.

Abstract: Abstract A microprogram sequencer for a microprogrammed control unit develops microprogram consecutive addresses, branches to subroutines with address saving and possible return to microprogram, as well as interrupting microprogram forcings with address saving of the interrupted microprograms. *          In order to allow the double saving of microprogram and sub-routine addresses in case of concurrent interruptions and branches, the sequencer is provided with two address generation loops each including a register.  The two loops have a common portion to which they accede through a multiplexer.  The first loop is further coupled to a saving register stack.  While the first loop executes the saving of a microprogram address and the latching of a branch address received from the second loop, the second loop executes a first updating and related latching of interruptingmicroprogram address.  During the following cycle, by command of the first microinstruction of the interrupting microprogram, the second loop performs a first updating and related latch of the interrupting microprogram address and the first loop saves into the register stack the branch address and performs a second updating and related latching of the interrupting microprogram address.
