Abstract: A data representation and protocol are provided to interface two networks. A plurality of information units to be transmitted from one network to another are formatted into a variable size block in accordance with the protocol. Each block contains a header field storing a total information unit count and a control information unit count. The remainder of the block stores the actual information itself, both control and data, in consecutive byte locations, with the actual control information located at the end of the block. The block can then be sent to another network for processing. A device in the other network need only reference the block header to determine whether the information contained in the block is control or data. This speeds the processing of large quantities of either all data information and/or control information.

Abstract: Signals to be processed, for example digitised audio signals, frequently occur in a regular sequence of data words, which are processed for example in a signal processor, successive data words being processed with the same programme. However, this programme generally does not need the full time between two successive data words, so that the remaining time can be used for the processing of further data words which are not time-critical. However, this remaining time is generally too short for the complete processing of such further data words. In order to create a continuous longer processing block for such further data words, the invention proposes that at least one of the regularly occurring data words be buffer-stored and processing carried out in immediate succession and that the time differences between the processing times of one of these data words and their period length be accumulated, until at the end of such processing no new data word is stored.

Abstract: An apparatus which adhesively binds a set of sheets (142) by applying a strip (154) having an adhesive on one surface thereof to the spine of the set. The strip is supported on a heated platen (146) which softens the adhesive. The spine (138) of the set of of copy sheets is pressed into the adhesive on the strip. The depth of penetration of the spine into the adhesive is controlled so as to form a layer of adhesive between the spine and the strip having a predetermined thickness. As the spine (138) of the set of copy sheets is moved into contact with the adhesive on the strip (154), it is damped (145) to absorb a substantial portion of the kinetic energy of the set of sheets to reduce the deflection and distortion of the set of sheets.

Abstract: This lock, which may be coded-keycard operated, has a set-table device on the inside of the door by which the maid, for instance, can be locked out. The lockout setting device is preferably in the form of a pushbutton or deadbolt turnpiece which manipulates a switch in the code-receiving circuitry. The lock-out setting is automatically cancelled when the latch is retracted. When the setting device comprises a deadbolt turnpiece, the deadbolt is biased toward retracted position and the setting device holds the deadbolt extended. When the latch is retracted in the latter version, the retraction cancels the lockout setting and permits the deadbolt to retract under the power of the dead-bolt biasing spring. 
     The invention also includes a non-code-operated embodiment in which a deadbolt is spring driven to retracted position as the latch is retracted in latching to protect the deadbolt, lock and door frame.

Abstract: Each of the pockets (3), which are arranged at regular distances apart and are moveable along an endless path, is provided with two vertically adjustable stops (14, 15) for the printed product (12) placed into the pocket (3). The stops (14, 15) are mounted displaceably in a pocket carrier (8). Within the pocket carrier (8) there is horizontally arranged a slide (18) which has two elongated openings (19, 20) of slight inclination to the horizontal. A projection (21, 22) on each stop (14, 15) is guided in the corresponding opening (19, 20) of the slide (18). A displacement of the slide (18) accordingly effects a vertical displacement of the stops (14, 15). A guide member (28) which is displaceable in the direction of the slide (18) on a carrier (29) fixed to the machine has a guide groove (32) for a projection (27) arranged on the protruding end of the slide (18). Upon the moving past of the pockets (3), the projection (27) moves through the guide groove (32) so that the slide (18) is brought into a corresponding horizontal position and the stops (14, 15) are brought into a corresponding vertical position. Upon change of the height of the printed product (12), therefore, only the guide member (28) need be newly set on the carrier (29) in order for the printed products (12) to lie at the correct height in all pockets (3).

Abstract: A magneto-optical disk having a magnetic layer (2) and a conductive layer laminated on a transparent substrate (1), and having a lubricant layer (7) provided on the conductive layer. Recording and reproduction on and from the magneto-optical disk are performed by means of a flying head. The flying head glides above and lands on the lubricant layer. The magneto-optical disk can therefore be removed from the device easily since a magnetic head does not adhere to a recording medium. Further, a depressing force exerted on the flying head is controlled so as to maintain a constant floating gap between the flying head and the recording medium. The depressing force is controlled by electrostatic capacity between an electrode, provided on a bottom face of the flying head, and the conductive layer. Consequently, highly reliable recordings can be made since a magnetic field intensity applied to the magnetic layer becomes constant. It is desirable that the lubricant layer (7) be composed of an organic binder containing a powder belonging to the ethylene tetrafluoride resin family.
