Abstract: A method for producing an information carrier in the form of a card, such as an identification card or pass, as well as an information carrier produced in accordance with this method. The information carrier comprises a plurality of plastic layers combined with one another into a block, at least one of which contains a photograph of the bearer and/or his fingerprint and/or other readable or machine-readable data in the form of a photographic layer. This photographic layer is produced and incorporated into the sandwich of plastic layers making up the identification card in that a specially prepared film is exposed to light, developed, fixed and dries, and then the carrier layer of this film sandwich is removed from the emulsion after the emulsion has entered into an adhesive bond with a first plastic carrier layer, this adhesion being substantially greater than the adhesion of the emulsion to the film's auxiliary carrier, which is to be removed.

Abstract: A prefabricated wall unit for log building construction is produced on a specially-constructed assembly frame by sequentially stacking a plurality of individual log units co-planarly and joining each log unit in sequence to the previously stacked log unit by lag bolts driven through the log units to integrate the logs in the wall unit. Longitudinal studs are affixed in relatively spaced relation to one side of the integrated logs and supplementary insulation is sprayed between the studs. A plurality of wall units are vertically arranged in relative abutting relation on and affixed to a conventional building foundation to produce a log structure, the wall units being joined to each other by the interdigitation of respective log units of abutting wall units and the driving of lag bolts through such interdigitated log units.

Abstract: A friction pivot joint where a headed fastening couples two components by passing through aligned openings in the components and having structure for preventing axial movement of the tail of the fastening. The joint is characterized by the shank of the fastening extending through a bushing of wear resistant plastics material located in the opening in one component. The bushing has integrally formed therewith a peripheral flange and the flange is sandwiched between the two components thereby preventing contact between the components. Friction in the joint is created from the plastics bushing and integral peripheral flange being placed under pressure by the fastening. The bushing has a length which is greater than the length of the opening in which it is located with the result that during assembly of the joint pressure created by the fastening causes the free end of the bushing to flow under the head of the fastening to be retained thereunder by retaining structure.

Abstract: A method and an apparatus are proposed for performing a comparison of patterns of invariable form, especially fingerprint pattern. By the application of a finger on a prism within a beam of light, a latent picture of fingerprint lines is obtained which is optically compared with a copy of the same fingerprint stored in memory or located on a card. After conversion into an electrical variable, an identification pulse results which is subjected to at least one test criterion and compared with a threshold value. Preferably the testing of a master symbol located on the inserted card is effected at the same time, comparing this with a copy of the same stored in memory within the appliance. If the test criteria show an agreement of the fingerprint with the fingerprint copy and/or of the master symbol with the copy of the master symbol then a positive assessment is effected, and access to a building, for instance, is furnished.

Abstract: A releasable retaining means for mounting on the inside of an outward opening closure element movable to open and close an opening. First and second mounting means (13 and 14) are respectively mountable on the closure element (11) and opening surround (12) with a stay (15) slidably and pivotably coupled to the second mounting means (14). Stay (15) is pivotably couplable by engagement means (22) to the first mounting means (13) and releasable therefrom by sliding stay (15) relative to mounting means (14) but only when the closure element is closed. Recoupling means (16, 24) automatically cause the engagement means (22) to couple to said first mounting means (13) when the closure (11) is moved into the closed position.The retaining means thus prevents closure element (11) from opening more than a predetermined amount unless the stay (15) is released from the first mounting means (13) prior to opening the closure element (11).

Abstract: An opto-electronic apparatus for reading out preferably coded information contained on a data carrier with high reliability and free of disturbances even when the insertion speed of the information carrier into an associated opening of the reading apparatus depends only on the arbitrary actuation by the operating person, including retrograde motions or stoppage of the information carrier. The apparatus is especially adapted to the read-out of information coded in a card as a pattern of alternating transparent and opaque areas which are subjected to infrared radiation whose passage or non-passage is detected by suitable detectors. The process of reading out the information contained in the data carrier is timed or clocked by a clock cycle generated from a clock trackcontained in the data carrier itself.

Abstract: A window stay for adjustable mounting of a window sash into a window frame which comprises a first mounting plate adapted for attachment to the frame of a window and a second mounting plate adapted for attachment to the sash of a window. A carriage is slidably mounted on the first mounting plate. An arm is pivotally connected by one end to the sash mounting plate and by the other end to the frame mounting plate. The sash mounting plate is further pivoted but at a point remote from the pivot coupling the arm to the frame mounting plate to the slidably mounted carriage. Means are provided which cause the carriage to be angularly displaced relative to the frame mounting plate during the initial opening and closing.

Abstract: A window stay for adjustable mounting of a window sash on a window frame. The stay comprises a frame mounting plate and a sash mounting plate with long and short arms joining the respective plates to one another. The ends of the longer arm are pivotally joined to the respective plates but the shorter arm is pivoted by one end to the sash plate while the other end is pivoted to a free sliding carriage on the frame plate. Means are provided so that the carriage can be locked in at least one position on the frame plate.

Abstract: A window stay for swingably mounting a window sash on a window frame, comprises a pair of vertically superposed stub mounting plates secured to one of the sash and frame, and at least one further mounting plate secured to the other of the sash and frame. A pair of arms pivotally interconnect each stub mounting plate with the further mounting plate or plates. One of the pivotal connections of the arms is a friction joint of special form.
