Abstract: Numbered quantities of sterilised swabs are kept in readiness for operations. In order reliably to avoid the possibility that a swab is left behind in the surgical wound, the invention envisages a package in which each swab is assigned its own receptacle. It is thus possible to determine at a glance, during the operation, whether all the swabs have been transferred back to the package.

Abstract: A process for the preparation of extracts with high content in anthocyanosides consists in treating plants, parts of plants or crude extracts with bisulfite ions to give anthocyanoside-bisulfite adducts. Said adducts are then eluted on non-ionogenic resins at pH 5-6 and the obtained solution is extracted with polar organic solvents immiscible in water. The obtained extracts have a constant and standardized composition in anthocyanosides.

Abstract: A process for producing structures from synthetic single-­crystal pieces having identical major component and crystal systems by chemically bonding to produce integration and simulation. From a physical viewpoint, synthetic single- crystal pieces can endure high and low temperatures, and rapid heating and cooling as they have,high melting points. Their hardness is considerably higher than non-crystals. From a chemical viewpoint, synthetic single-crystal structures provide superior chemical resistance and are free of corrosion and quite stable chemically. Structures produced from synthetic single-crystals provide features superior to non-cyrstals but are not as advantageous because they are so hard that they are not easily dissolved and processing them is difficult. The greatest difficulty with synthetic single-crystals is that unlike non-­crystals they cannot be melted together. The process of the present invention makes structures of synthetic single-crystals that are placed together like non-crystals. Therefore, with the process of the present invention, new synthetic single-crystal structures of larger or smaller complicated precise shapes having applications in optical, chemical, and physical fields may be produced. The structures from synthetic single-crystal pieces are comprised of a plurality of colorless synthetic single-­crystals or colored synthetic single-crystals having the came prime component and either no color or color impurities contained therein. The synthetic single-crystal pieces are optically polished on both parallel ends which intersect at a particular crystal axes with a particular angle and the polished opitcal end faces are optically bonded with identical axes, identical axial angle, and identical axial ratio. The single-crystal pieces are all uniformally heated to chemically combine them to integrate them together.

Abstract: Synchronizing buffer which synchronizes data link data with the channel clock (24) such that one character is transmitted onto the data link (18) for each channel clock. The synchronising buffer disclosed includes a first-in-first-out (FIFO) buffer which receives data characters from a data channel buffer, and outputs them onto the data link (18). When the channel clock (24) is stopped, the synchronizing buffer circuit places idle characters on the data link with the proper disparity. When the channel clock (24) re­starts, the circuit synchronises the sending of restarted data characters with the idle characters placed onto the link such that there is an intelligible string of characters on the data link at all times.

Abstract: An electrode tube cathode (1) having improved electron emission properties is produced by suspending an alkaline earth metal carbonate powder and scandium oxide powder in a solution of nitrocellulose, regulating their particle size, applying the suspension on a nickel base metal surface (1b) such that the coating density is not greater than 2 mg/mm³, and heating the layer of the carbonate in vacuum to a temperature of 800 - 1200°C to decompose to the oxide, thereby forming a porous electron emission layer (30) wherein scandium oxide is dispersed in an alkaline earth metal oxide on the base metal. The resultant electron emission layer (30) has a porous structure, and hence the stress between the layer and the base is reduced. This appears to suppress the swelling of the layer and the peeling of it away from the surface of the base.

Abstract: A laser alignment system includes a transmitter and one or more receivers. The transmitter produces an alignment field by projecting laser energy in a non-planar reference cone, and the receivers locate this reference cone with photodetectors (12, 13). The laser energy in the alignment field is modulated at 8 kHz and the signals produced by the photodetectors (12, 13) are filtered by band pass filters (100a, 100b) and amplified to increase the range of the system. Level detectors (105a, 105b) receive the filtered and amplified electrical signals and produce level signals indicative of the magnitude of the modulation frequency signal component therein. Each receiver operates a display (5) which indicates when it is aligned in the reference cone. Locking means (130, 131, 133, 138, 140, 141) are coupled to the band pass filters (100a, 100b) and produce a lock signal which indicates that the receiver is positioned in the alignment field.

Abstract: A perforating gun apparatus comprises a plurality of perforating guns (10,12), each gun containing at least one charge (16) and a novel arming, testing and firing apparatus. The arming, testing and firing apparatus arms a first charge in a lowermost perforating gun; however, the arming of the first charge in the lowermost perforating gun allows a tester disposed at the well surface to determine the identity of the lowermost perforating gun to be detonated. Furthermore, the arming of the first charge in the lowermost perforating gun also enables the arming of a second charge in an adjacent perforating gun of the gun string. In the event the first charge is not armed as expected, the arming, testing and firing apparatus in the lowermost perforating gun bypasses the lowermost perforating gun and begins to arm the second charge in the adjacent perforating gun of the gun string. A novel housing for a perforating gun includes an isolated chamber (18) in which a charge (16) is mounted, the chamber having two opposite walls (20,22), one wall being circumferentially rotatable and including a radially disposed detonator (24). Since a detonating cord (26) is longitudinally disposed in the chamber, the circumferentially rotatable characteristic of the one wall in association with the radial disposition of the detonator provides a safe arm feature of the perforating gun.

Abstract: A device is described for scanning an information plane having tracks in which a track to be scanned is tracked by means of the three-beam method. Each one of the three beams is push-pull detected by three split detection systems (10, 11, 12). A position signal Ep which is a measure of the position of an adjustable element (9) in the device determining the transversal position of the spots with respect to the tracks is derived from the detector signals by means of a special electronic circuit (24-26, 30-32). A control circuit 33 can correct the position of the element by means of the position signal. A normalizing signal with which the position signal Ep is made independent of the intensity of the beams can also be derived from the same detector signals.
