Abstract: An automatically operating boat locking assembly includes a spring-loaded bolt which engages through the bow eye of a boat to secure the boat on a trailer and which can be withdrawn to free the boat for removal from the trailer. The bolt can be rotated in its withdrawn position to engage a portion of a frame of the assembly which prevents return of the bolt to the extended locking position. A trigger member carried by a frame of the locking assembly is contacted by the bow eye of the boat as the boat approaches the trailer and rotates the bolt whereupon the spring associated therewith returns the bolt to the locking position, through the bow eye locking the boat on the trailer.

Abstract: A dispenser for cosmetics has vertically extending alignment means on its side walls whereby similar dispensers can be readily assembled into a modular arrray by vertical relative motion between two dispensers. A mounting plate securely fastened to a wall surface cooperates with mounting lugs on the rear of the dispenser for securely mounting the dispenser on the wall.

Abstract: A solar-powered system for supplying large quantitites of usable power consists of an array of photo-voltaic cells which drive an electrolysis generator in which water is converted into oxygen and hydrogen gases. The oxygen and hydrogen gases are initially stored and then mixed in stoichiometric amounts and delivered by means of a water-cooled discharge nozzle to a burner chamber in which the gases are recombined. High pressure steam produced by the oxygen/hydrogen recombination is discharged from the burner to a turbine generator. Condensed water is collected from the turbine and used as distilled water for domestic uses or returned to the electrolysis generator.

Abstract: A probe for the determination of the concentrations of volatile components in liquids or gases comprises a probe body consisting of two essentially tubular, coaxial parts which are disposed one within the other. The external part carries in its front zone a permeation canal, formed by a thread, and covered by a tubular permeation membrane. A protective sleeve surrounds and is spaced from that membrane. At its front end, the external part is closed by a plug-like closing member which defines a holding space for a gas sensor or for an adapter connected with an external measuring instrument. A carrier medium is fed to the permeation canal via a ring-shaped carrier-medium feed canal between the external and internal body parts and the carrier medium is returned via a return line disposed inside the probe body. In the zone of attachment to a connection piece, the external part carries an O-ring and the outside of the screwed-on protective sleeve is aligned with the outside of the mounting zone.

Abstract: A sterile, disposable, receiving blanket for a new born baby comprises two bonded layers of sheet material, one of which is relatively absorbent and receives the baby, and the other of which is relatively liquid impervious and acts as a backing sheet. Two sleeves are provided which extend along two opposite edges of the backing sheet on the obverse side from the receiving sheet. Each sleeve is open at one end to receive the hands, wrists and forearms of the nurse or pediatrician using the blanket and is closed at its other end to prevent the hand from contacting the receiving sheet or the baby. The sheets are configured to provide a tapered pouch located in the receiving surface of the blanket and extending across the blanket parallel to and centrally located between the two sleeves. The pouch has a deep end towards the open end of the sleeves which, in use, receives the head of the baby to assist drainage of liquids to the baby's mouth during the initial moments after birth.

Abstract: An amusement device comprises a case in which is housed a figure. When the case is closed the figure is hidden within the case and covered by a lid. An operating button accessible when the case is closed can be depressed to actuate a mechanism which opens the lid of the case simultaneously causing the figure to rise from its stored position and to turn through a 90.degree. angle to an erect position in which it stands out from the case.

Abstract: A dispenser for pressure-sensitive adhesive labels on a web of release material in which a label-bearing web is withdrawn from a supply coil past a peel edge at which the direction of travel of the web reverses so that the labels separate from the web and advance towards the surface to be labelled, wherein the spent web is taken up by a take-up spool, and a friction roller rotatably mounted in the dispenser for contact with the surface to be labelled rotates as the dispenser is moved over the surface, the friction roller being operatively connected to the take-up spool so that both rotate at substantially the same surface speed and the labels are dispensed at substantially the same speed as the dispenser is moved but in the opposite direction.

Abstract: A puzzle comprises at least two relatively rotatable members in contact with one another and pivoted together about an axis normal to their contact plane. Exterior surfaces of the members are formed with tracks having their entry and exit points disposed equi-angularly about said axis and equidistant therefrom in said contact plane. Accordingly relative rotation of the members in equiangular steps brings about alignment of the several tracks in different configurations. A multiplicity of movable elements substantially fill the tracks and are displaceable therealong when the tracks in the first member are aligned with those in the second. The puzzle may in its initial position have circular tracks each filled with beads of a different color or marking, the puzzle being manipulated to randomise the beads and then to return them to their original pattern or to form another intended pattern.
