Abstract: A piezo-electric ink jet droplet generator (1) has a body part (2) having a first ink supply passage (10/11) and a second ink supply passage (12) extending generally perpendicularly therefrom through a protrusion (20) of the body and opening at an end face (14) of the protrusion. A piezo-electric crystal (6) is attached to a surface of the body closely spaced from the first ink supply passage and adjacent the end of the second ink supply passage which connects with the first supply passage. A nozzle (17) is mounted in a cap (3) which is secured to the end of the protrusion (20), the nozzle being in alignment with the second supply passage (12). The inner surface (13) of the cap surrounding the nozzle is spaced from the end face (14) of the protrusion thereby forming, in use, a disk (21) of ink between the inner face of the cap and the end face of the protrusion. The cap is sealed to the protrusion by means of a flexible seal ( 16) and engaged with the protrusion by means of a quick-release coupling (9,19).

Abstract: The present invention relates to vectors useful for identifying eukaryotic regulatory sequences and to a method for identifying these sequences. The vectors comprise a first nucleotide sequence which allows for replication in a eukaryotic host, a second nucleotide sequence which codes for a first product that controls replication at said first sequence, and a third nucleotide sequence which codes for a second product that is detectable. The method comprises inserting putative eukaryotic regulatory sequences at a position on the 5'-side of the second sequence and measuring the production of the second product.

Abstract: A drill bit for core boring of the type provided with a multi-layered bit head, so constructed that when the blades of the upper-layered bit head have become worn out, it is possible to easily withdraw them without removing the bit from the bore. The core boring operation is then continued without delay by using the blades of the newly exposed lower-layered bit head. The drill bit is also so constructed that it is possible to eliminate any displacement of the upper layer blades from their fitted position on the blades of the lower layer blades during drilling by using the upper layer blades and at the same time, it is possible to easily disengage the engagement between the bit body and the upper layer blades when the upper layer blades have become worn out.

Abstract: A water soluble phenolic resole-urea composition useful as a binder which remains infinitely water-dilutable and free of sediment after one month of storage at 0.degree. C. and is made by the reaction of urea with the free formaldehyde in a phenolic resole under acid conditions, followed by the further addition of urea at neutral or slightly basic conditions.

Abstract: 4,4,7-trimethyl-3,4,7,8-tetrahydro-2(6H)-naphthalen-one is obtained by an elimination reaction from 3-oxo-.alpha.-ionol by way of direct addition thereof to a solution of a protonic acid in an inert solvent at an elevated temperature, or following its conversion into a low-carbon alkyl ester, particularly acetate, by way of the treatment of the latter, preferably with sodium acetate, in a polar non-protonic solvent at 150.degree.14 300.degree. C., wherein the output can be increased by raising the temperature of reaction. The product of the process is suitable, in pure form or as mixed with simultaneously produced 3,5,5-trimethyl-4-butenylidene-cyclo-hex-2-en-1-one, as an odiferous substance or as a fragrant substance for foods and tobacco.

Abstract: An ocean launching apparatus of space rockets comprises a launch pad platform having a floating-island structure and a semi-submersible hull for loading and transporting the launch pad platform. When the apparatus reaches an intended ocean area, a rocket set on the launch pad platform is floated from the hull in a semi-submersing state on the ocean together with the launch pad platform and moved to a launching site. In this way, it is possible to provide an ideal launching site of space rockets, increase an economical efficiency of launching of space rockets, and guarantee the safety if an accident should occur.

Each articulation means comprises a first rotatable coupling for permitting rotation of the solar array about a first axis substantially parallel to the surface of the spacecraft body, a second rotatable coupling for permitting rotation of the solar array about a second axis normal to the first axis, and a third rotatable coupling for permitting rotation of the solar array about a third axis normal to the second axis and parallel to the longitudinal axis of the array.

Abstract: A method and apparatus are provided for electrophoresis of macromolecules. The macromolecules are separated through a tube gel which is connected to an upper electrode buffer reservoir by means of a liquid bridge. The tubes themselves are neither permanently attached nor removably attached to the apparatus but merely rest in and abut appropriate positioning devices. Formation and maintenance of the liquid bridge is promoted by means of hydrophobic surfaces. By balancing the hydrostatic pressure of the upper chamber upon the porous or perforated surface, with the surface tension of the liquid, no leakage from the upper chamber results except by means of the stable liquid bridges.

Abstract: A programmable printing system for product marking applications is described in which a printing member is carried by an articulated mechanical arm, such as a robot arm. Due to the enhanced maneuverability and reach of the articulated arm, printing can be carried out on surfaces which would not be accessible to conventional types of conveyor-mounted product marking devices. The articulated arm is controlled by a programmable control means which can be reprogrammed as needed in order to print on objects having different sizes, shapes and orientations, or to print at more than one location on the same object. The apparatus finds particular utility in connection with pad transfer printing, including multicolor pad transfer printing, but is also applicable to other printing methods.

Abstract: A radio position determination and message transfer system is implemented using a number of satellites in geostationary orbit for relaying interrogation and reply signals between a ground station and a user-carried transceiver. Message information can be exchanged between a given user transceiver and the ground station, as well as between different user transceivers. The user transceiver is provided with means for monitoring the quality of the radio communication link between the transceiver and one or more of the satelites, based on errors detected in the received interrogation signals. The transmission of a reply signal by the transceiver is enabled only when the link quality is found to be acceptable. The reply signal may contain message information or may constitute a request for a position fix. In the latter case, the transceiver may be configured to await favorable link quality to more than one satellite before the reply signal is transmitted.
