Patent DE-2614031-A1 (DE)
Title: Universal cleaning wick system for firearm barrels - has cotton yarns connected by finer yarns for ready bore size adjustment
Inventor: WALDENFELS GEORG FRHR VON
IPC: F41A29/02
Filed: 1976-04-01
Abstract: The gun barrel cleaning wick is esp. for small arms. The wick consists of several, pref. cotton yarns braided with fine yarns into a trapezoidal shape. Longer wick lengths ensure uniform contact press. even on larger barrel inside walls. The number of the wick forming yarns (11 to 18) and the strength of their brading (19) depend upon the given uniform contact press. The wick properties are such that on using a wick for the smallest barrel bores the wick dia. is automatically reduced. On cleaning larger bores the wick is automatically adjusted. The number of wicks is increased for still larger bores.

Title: Battery powered radio transmission system - saves power by switching off during breaks and by matching transmit power to signal strength
Inventor: GUNTERSDORFER SIEGFRIED
IPC: H04B7/005
Filed: 1976-08-09
Abstract: The free-space transmission system, e.g ultrasound remote control or IR link between headphones and tv receiver, saves power by matching the transmit power to fluctuations in a signal strength and by switching off the system during breaks in transmission. Alternatively, if the transmitter and receiver are not local but relatively far apart so that each is subject to different conditions, an additional signal may be used to control the transmit power according to the strength of the signal received by the receiver. This additional signal may be AM or FM modulated onto the wanted signal.

Title: Safety interlock for mechanical switching levers - has three locking levers operated in sequence to release shaft which turns through limited angle and shifts axially
Inventor: MERKLE PAUL
IPC: G05G5/00
Filed: 1976-09-08
Abstract: The safety interlock system for mechanical levers consists of a swivel linkage (16) attached to the main operating shaft (7).
