Abstract: SELF-SEQUENCING DATA BUS ALLOCATICIN SYSTEM                  Abstract of the Disclosure A plurality of data communication devices of the type which operate to communicate with a data bus responsive to the receipt of a prescribed voltage are triggered automatically in a prescribed sequence without separate addressing from a central point.  Each data communication device (which may be uni- or bi-directional) is connected to a common multi-wire electrical cable by means of a control station, which taps a power supply line from the main cable and directs the power to its corresponding data communication device.  The data communication device is thus activated so as to permit it to transmit its data onto the data bus of the main cable.  Upon completion, the data communication device ceases drawing power which indicates to the system that it has finished, whereupon the next-in-line control station initiates the process with its corresponding data communication device.

Abstract: Abstract Multiple-resolution, interlace, ink-jet printing is accomplished using a single array with multiple nozzles by assuming a psuedo pel (picture element) spacing k' between the nozzles.  The ratio between the old resolution and the new resolution is k'/k where k is the actual pel spacing between the nozzles.  The print-data must be processed and the print head moved based on the psuedo pel spacing k'. The array of nozzles will still print in an interlace manner so long as k' and Nt (the total number of ink jet nozzles used) have no common factor.

The counter includes a cashier's section (3) as well as a conveyor band (5) advancing articles (15) to said cashier's section. The counter (1) helps in defin-ing a passage (9), through which the carts (2) pass the cashier's section (3). The counter (1) includes a bracket-shaped receiving section (10), the distance (a) of which from the floor on which the system is positioned is only a few millimetres greater than the distance (b) from the surface (12a) of the freely accessible loading surface (12) of the cart to the floor. The passage (9) is of a width (c) smaller than the width (d) of the shopping cart (2) so that the shopping carts (2) can only be pushed forward manually in the passage (9) when they are positioned perpendicular to the receiving sec-tion (10) and their loading surface (10) simultaneous-ly extends therebelow. In this manner the receiving section (10) brushes off the articles (15), if any, present on the loading surface (12) of the cart when said cart is to pass the system. In this manner a system is obtained which in a very reliable manner prevents the customer from passing through the sys-tem with his articles without having paid for all said articles at the cashier's section.

Abstract: "HEATING SYSTEM OR FURNACE"          ABSTRACT OF THE DISCLOSURE         Conventionally, furnaces used to provide heat utilize a gaseous liquid or solid fuel source all of which requires venting of one form or another.  Electrical power is also used to energize resistive type heaters but the operation requires special wiring and is relatively expen-sive to operate.  This system utilizes a closed circuit heat exchange system including a main reservoir containing a circulating fluid such as oil.  A closed circuit heat generating system includes a pump and a further reservoir circulating a fluid such as oil through a restrictor valve situated within the liquid in the main reservoir thus generating heat which is picked up by the fluid in the main generator and transferred to the heat exchanger.  Forced air or hot water may be heated by the heat exchanger and conveyed to remote locations in a building by conventional means and the restrictor may be adjustable to control, within limits, the heat generated by the forcing of the fluid through the restrictor valve.
