Title: Pneumatic splicing head test - passes gas through empty head to monitor its performance against reference values
Inventor: HORAK DIETER
IPC: B65H69/06
Filed: 1989-12-23
Abstract: To test the operation of a pneumatic yarn splicer at a textile machine, such as a winder, before the yarn ends are laid in the splicing channels gas is delivered for a given time period and the outflow of gas at a given opening in the splicing head is measured, and compared with a reference value, obtd. from an identical splicing appts... Any deviation shown by the comparison is taken as a criterium for the operation of the splicing head under test to give a trouble-free splicing action. Pref. the  pressure of the emerging gas from the splicing head is measured at the determined opening, for comparison, or its speed is measured as a monitoring value, or the gas temp. is ued. At least two qualities of the gas are measured simultaneously for comparison with reference values. In addition, the temp. of the splicing channel in the splicing head is measured. The test appts. (20) has a measurement tube (21) as the splicing gas feed, with an exchangeable adaptor (22) to connect it to the splicing head (10c) of the splicing appts. (9c). A monitor (26,30) at least establishes one value of the gas, through a pressure monitor, a flow speed monitor (30), and a thermal sensor (26). At least two monitors register two different aspects of the gas. The test appts. (20) has a further thermal sensor to measure the temp. of the splicing head (10c). A computer (50) is connected (26a,30a) to the monitors (26,30) for the measured values to be displayed, stored and to be compared with reference values. The adaptor (22) allows the test appts. (20) to be connected to different splicing heads at various splicing units, and the adaptor (22) is exchangeable and of a material with a low thermal conductivity. An insert (28,29) in the measurement tube (21), in front of the speed monitor (30), eliminates any twist in the gas stream.

Title: Security alarm device for transport container - has disc locking device to container handle upon rotation of lock through 180 degrees
Inventor: REICHERT MANFRED
IPC: A45C13/24
Filed: 1990-02-13
Abstract: The alarm device is fitted to a container (5) used for transporting money, documents or valuables, so that the container carrying handle (6) fits through an opening (11) in its base plate.

When the lock (4) is rotated through 180 degrees to couple the alarm device to the container (5), the disc (1, 2) operates a microswitch (9) for initiating a state of readiness, with a pivoted lever (8) cooperating with a second microswitch (10), controlling an electronic alarm which is activated upon release of the lever (8). ADVANTAGE - Allows use with various different containers.

Title: Safety catch for semi-automatic weapon - retains firing pin in safe position if weapon is accidently dropped
Inventor: LUDWIG WALTER
IPC: F41A17/72
Filed: 1990-04-25
Abstract: A semi-automatic weapon has a firing pin (1) which is struck by the firing hammer (15) when the trigger is actuated. The  firing pin is normally held in a safe position by a spring loaded catch (4) which engages a slot in the side of the firing pin. The action of the trigger lifts the firing pin clear of the catch to enable it to move forward and detonate the cartridge. In the event of the weapon being accidentally dropped and the firing pin moving, due to its inertia, to the firing position, the inertia of the sliding catch (14) overcomes the force  of the sprint and moves with the firing pin to hold it in the locked position. USE - Safety catch for semi-automatic weapon.

IPC: F16B13/06
Filed: 1990-05-07
Abstract: Fasteners, which are used for fastening high loads, are anchored in the drilled hole by means of an expanding body which is drawn into an expanding sleeve. If high instantaneous loads occur on the fastener, for example because of earthquakes, there is a risk that the fastener may break out of the drilled hole. 
<??>In order to ensure that the fastener continues to retain its retention function, even after the occurrence of high excess stresses, the inner hole 14 of the expanding sleeve 11 has a first cylindrical section, which originates from its front end and corresponds approximately to the length of the expanding cone 5 of the expanding body 6, having a diameter corresponding to the smallest diameter of the expanding cone 5. Adjacent to this first section is a second, conically expanding section, which continues cylindrically at its maximum diameter. In addition, the longitudinal slots 12 end in the conically expanding section of the inner hole.
