Patent DE-2558692-A1 (DE)
IPC: E05B15/08
Filed: 1975-12-24
Abstract: The gun-carriage bolt (1) for safeguarding a lock located behind its guide sleeve is protected by means of a lock plate (4) against being pulled out in an unauthorised manner. In order to prevent the possibility that, in the event of forces which destroy the locking plate or the bolt region engaging behind the locking plate, the gun-carriage bolt will nevertheless be pulled out in an unauthorised manner, it has, along its course, at least one spreading region (5) which can be spread up against the guide sleeve (2) in the event of a tensile or compressive force acting in the direction of the gun-carriage bolt (1). If the gun-carriage bolt is displaced counter to the resistance of the locking plate, this results in an additional securing as a result of this spreading and a consequential clamping in the guide sleeve (2). <IMAGE>

Title: Sag compensation for temp. resistant conductors - employs spring and lever to maintain tension coupled to high temp. conductor
Inventor: REUTHER WOLFGANG DIPL ING
IPC: H02G7/02
Filed: 1976-06-24
Abstract: The application is principally to conductor installations in substations where steel supported aluminium conductors are used. These permit safe operation at continuous temp. up to 473 deg.K, but have a correspondingly large linear expansion. To permit the use of such cables without closer support spacing, the sag due to expansion is taken up by a spring tensioned lever. A cranked lever (1) is hinged (13) to the transmission mast (3) and attached at one end to the cable (14), and at the other (11) to a coil spring (2). The spring assembly is also attached to the mast. If the sag tends to increase, the load on the pretensioned spring (2) tends to decrease. To equalise the acting forces the lower lever arm is pulled towards the spring, causing the upper arm to stretch the cable thus compensating for the sag.

Title: Sterilising of contact lenses - is carried out in closed vessel contg. sterilising soln. subsequently decomposed by catalyst
Inventor: THOMAS MICHAEL D
IPC: A61L2/18
Filed: 1976-08-27
Abstract: Method for sterilising objects e.g. contact lenses with a soln. in a closed vessel in which the catalyst is initially within the vessel out of contact with the soln., and the strength of the soln. is maintained for a desired period including the stage in which the soln. and catalyst remain out of contact with each other. At the end of this period, the vessel is repositioned to bring the catalyst into contact with the soln. The soln. is allowed to decompose to a level at which its strength is below a given concn. This method allows a sufficiently long period for action on the lenses and therefore perfect sterilisation.

Title: Automatic location of blank section on magnetic tape - has level switching circuit which reacts to difference in amplifier output between blank and recorded tape
Inventor: YASUNAGA TATSUHIRO
IPC: G11B15/10
Filed: 1976-08-27
Abstract: A search control circuit enables a section of recorded tape to be transported at high speed. When a blank section is located the speed is reduced to the normal recording speed. The output of the playback pick-up (1) is coupled to an amplifier (2) with a coupled search selection switch (3). A charge switching stage (4, 6, 31) is coupled to a charge-discharge stage (7, 9) operating into a Schmitt trigger (11, 12). An control stage (16, 17) allows the speed changing solenoid (18) to be activated. During search control operation, the amplifier output is processed to hold the output transistor (16) in the low state. When a blank tape section is encountered the trigger stage switches the output to activate the speed changing solenoid.
Patent DE-2644221-A1 (DE)
Title: Magnetic tape cassette over-tension detection - initiates drive switch=off by using electromechanical linkage with auxiliary motor drive
Inventor: WONDRA ARTHUR
IPC: G11B15/16
Filed: 1976-09-30
Abstract: The safety mechanism is for use with magnetic tape cassettes which detects overtension in the magnetic tape and rapidly removes the drive from the tape using a small auxiliary motor and an associated linkage. The mechanism is sensitive, simple and quick acting, and, in addition to normal tape drives, is suited to slow tape drives used for medical recording purposeS. A two spool (2, 3) magnetic tape (4) cassette (1) is mounted in a playing unit so that the tape is driven by a rubber capstan (13) and pinch roller (12) past the read-write head (7) over a number of guide rollers (5, 6, 8, 9, 10) in the cassette. A small test head (15) attached to a spring (25) mounted lever (14) is depressed by the tape when the tension exceeds a defined threshold, and this closes a pair of contacts (17) which activates an auxiliary motor (19). This in turn operates an actuator (29) peg and lever (32, 31, 27) array which immediately removes the entire drive, including the capstan (13) from the tape in the cassette thus avoiding the recording inaccuracy or damage.
