Abstract: A punch for forming a rectangular opening in cinder block. The punch includes a housing having a wall with a toothed edge and which is generally rectangular in crosssectional shape. A tube is secured to the housing and extends perpendicularly outwardly from the toothed edge so that the axis of tube is positioned within the interior of the area circumscribed by the toothed edge of the housing. A rod having a piercing point at one end is slidably mounted within the tube so that the piercing point is contained within the housing while the other end of the rod protrudes outwardly from the free end of the tube. In use, the housing and piercing point are both positioned against the cinder block. The rod and free end of the tube are then struck by a hammer in order to form the rectangular opening in the cinder block.

Abstract: A device for manual or automatic opening of an aircraft safety equipment box includes a pin fixed to the box door, a pivotable hook engageable with the pin, and a resilient return assembly associated with the hook. The return assembly has a main spring urging the hook to a disengaged position and a locking lever pivoted about the same axis as the hook. In its locked position the lever abuts and holds the same part of the main spring as holds the hook in its engaged position. In the release position the lever frees the main spring to drive the hook to disengage it from the pin. The return assembly further has a secondary spring for returning the lever to its release position and the hook to its engaged position. The return assembly includes a release plate locking the lever in its locked position. Displacement of the plate causes the hook to disengage from the pin.

Abstract: A method for inputting data representing an engineering drawing to a computer aided design system. The method comprises the steps of creating the engineering drawing on quadrille paper or graph paper having criss-crossing lines. After creation of the drawing, the drawing is scanned by an optical reader which produces an electrical output signal representative of the drawing data. This output signal is electrically connected as an input signal to the computer aided design system. When editing the drawing, a computer generated grid pattern corresponding in scale to the criss crossing lines on the quadrille paper is superimposed on a video monitor of the computer aided design system thereby facilitating editing of the drawing on the computer aided design system.

Abstract: A combined trolley and seat unit has an inverted U-shape main frame with principal frame side members carrying ground-engaging wheels and having a main frame support rigidly fixed thereto and to a projecting bag support which carries the lower end of a bag the upper end of which is hooked by a pocket over a hook. A folding seat frame having a U-shape leg frame is pivotally carried on the main frame on the side thereof remote from the bag-like container and is movable between a folded position lying substantially parallel to the main frame and an unfolded position in which a front leg frame to which the seat frame is attached contacts the ground and the wheels are spaced from the ground to allow the unit to be used as a seat with no risk of rolling movement.

Abstract: There provided is a pressure detector accurate in operation and high in reproducibility to have a resistance circuit substrate provided with at least one pair of electrodes and forming a resistance circuit between the electrodes through printing or other means, a block contact maker formed of a conductive elastic material to a shape ready for deforming, which is characterized in that the block contact maker is kept in contact with the resistance circuit substrate at all times, the block contact maker is deformed according as the state shifts from non-pressurized to pressurized to change a contact area gradually with the resistance circuit substrate, thus forming a variable resistance circuit parallel electrically with the resistance circuit substrate.

Abstract: A system for automatic control of the fuel mixture strength supplied in slow-running conditions to a heat engine having a fuel injection system and means for supplying supplementary air in adjustable quantities, comprising first means for periodically varying the quantity of supplementary air supplied to the engine and for detecting the consequent variation in the slow running of the engine for the purpose of obtaining activation for second means for modification of the quantity of fuel supplied to the injectors of the system for compensating the variation in the strength of the mixture.

Abstract: A method and apparatus for applying a cover to a cushion of larger size than the cover by forcing the cushion into a confining chamber which reduces the size of the cushion. The cover is then slid over the cushion. The cushion is then expelled from the chamber taking the cover with it. The cushion expands within the cover as it leaves the confining chamber.

Abstract: A measuring instrument having a column 2 mounted on a base and a sliding unit 3 adapted for vertical displacement on said column 2. The sliding unit 2 has a housing 9 and a plate 10. The housing 9 is suspended on the column 2 by means of a cable 7 which is provided with a balancing weight. The plate 10 carrying a gauging element 5 is operatively connected by a counterweight device 17 to the housing 9. The counterweight device 17 has a lever 16 which is mounted on the housing 9. Lever 16 has a weight mounted on one end thereof. The other end of the lever 16 accommodates ball bearings 21 which serve to support plate 10 through cams 22. The instrument has a latching device 23 for establishing a zero position between plate 10 and housing 9 and for enabling adjustment of a measuring force.

Abstract: An impact apparatus, e.g. for moving portions (2, 3) of two elements (4, 5) away from each other by a wedge shaped tool (1), which is introducable between said portions, comprises a carrier (9), to which the tool is attached and which is movable relative to a body (10) of the apparatus. An impact member (11) is also movable relative to the body. A movement transmission device (12) acts between the carrier and a device (13) for activating such force influence on the impact member that it is caused to apply an impact on the carrier. The apparatus is so designed that when the carrier (9) is displaced due to actuation of the tool, the movement of the carrier is transferred via the transmission device to the activating device, which causes force influence on the impact member. The activating device (13) may be a valve for pressure fluid supply.
