摘要:
A method and apparatus for welding thermoformed sheets of plastic material having lands formed therein such that the lands are welded to one another utilizing tubes which are positioned to be in line with the lands in a stack of thermoformed sheets so as to direct hot and cold gas to the lands to complete the welding process. In some embodiments, a plurality of tubes are inserted from opposite sides of blocks of stacked thermoformed sheets such that the tubes enter cells defined between the sheets of the block.

A postage machine includes a first meter portion comprising postage means commanded by a first microprocessor (50), a keyboard (22) and a display (21 ), and a second base portion comprising a second Microprocessor (53). The first and second microprocessors, in a normal mode, mode carry into practice a communications protocol adapted to have transmitted to the base messages representative of at least some of the commands acquired on the keyboard (22) and to have retransmitted from the base to the meter the commands executable by said meter, in such a way that, from the keyboard (22) of the meter, at least certain functions cannot be commanded unless the commands relative to such functions pass through pass through the base (12).

The invention includes a device and a method for recognizing the instantaneous position of a plurality of mechanical parts, the parts being linearly and incrementally movable between a departure position and an arrival position. The device includes a plurality of radiation modifying tags respectively associated and movable with the mechanical parts. There are a plurality of pairs of radiation emitters and receivers located on the opposite sides of the parts at incremental positions, whereby the pressence of a tag between a given pair causes modification of the radiation received by an associated receiver. The device further provides for generating detect signals from the receivers, and for recognizing that corroborating detect signals from the receivers correspond to a specific set of positions of the mechanical parts.
摘要:
Starting from a herbaceous cutting, which may be derived from in vitro culture, of stock and of a herbaceous scion, the process consists of inserting the scion (12') having a single bud, into the stock cutting (12), by bevelling the lower end 15 of the scion 12' from two sides 17, 18, by slitting the upper end of the stock cutting in its middle, and by subsequently assembling the two parts 12, 12' by joining 20, of transferring the base of the abovementioned grafted unit into a development medium 21, of moistening the development medium 21 with a nutrient solution and of subsequently placing this unit in a container with a water-saturated atmosphere and at a temperature above 20.degree. C., while suppressing the bud 22 of the stock and growing the saplings in the greenhouse or under a polyethylene tunnel until the desired stage of growth.

The invention relates to a package accommodating a plurality of primary containers arranged in at least one row. The package includes a wrapper (10) of foldable sheet material wrapped about the containers and which partially can be removed whereafter each container is detachable from an adjacent container such that each detached container is left with a part of the wrapper (48-51) which provides a handle by which the container can be grasped.

A method uses portable objects where the reading and writing of data in the memory are free, owing to the writing in the latter, if necessary, of elements which can be prepared and verified only if secret information kept both in a secure memory at the control center and in a secure memory in the machine with which the transmission is carried out is known.

An electronic franking machine has a data reader for reading data stored in a microcircuit fitted in a chip card and includes a receptacle with respect to which are disposed a predetermined location and a punching mechanism.
摘要:
The invention relates to materials and method for forming composite packages comprising a first flexible material (11) and a second relatively rigid material (12) which are connected together without the use of additional connecting materials. The connection is achieved by causing the flexible material (11) to be deformed to cooperate in tension with interrupted zones (19) of the relatively rigid material (12). Many different packages may be formed for a variety of uses but the invention is particularly suitable for connecting a heat shrinkable plastics body part to a paperboard or like sheet material end part.
