Patent DE-2436625-A1 (DE)
Title: Filter tipped cigarette - has conventional filter followed by short length of compressed tobacco on end of conventional cigarette
Inventor: HEINE MICHAEL
IPC: A24D1/00
Filed: 1974-07-30
Abstract: The filter cigarette is made up of a normal length of tobacco followed by a suitable conventional filter length, and finally a length of tobacco which is shorter than the filter, so that the tobacco comes in contact with the mouth of the smoker, giving a more pleasant taste than the filter. The short tobacco length can be compressed more than the main length, and acts as a filter, and may also be impregnated with a flavouring substance. The whole arrangement gives a highly efficient method of retaining the tars from the cigarette smoke. In an alternative method the separate filter and compressed tobacco length may be replaced by a mixture of filter material and tobacco.

Title: Locking mechanism for moving switching members - has locking bolt on shaft and blocking slider driven into bolts path by control device
Inventor: KOHLER WERNER
IPC: H02B11/133
Filed: 1974-09-03
Abstract: The locking mechanism for moving switching members has a releasable blocking element (10) on the moving switching member (1), to block the locking bolt (3) motion towards stops on the housing. The blocking element is released by a mechanical control device. The locking bolt is mounted on a shaft (4) drawn mechanically in the direction of locking. The blocking element is constructed as a slider moving in the path of the bolt and having a projection that engages the control device. The advantage of the mechanism lies in its being unaffected by the pressure increase due to arcing between the switch contacts.

Title: Release mechanism for roller blind shutter - has spring-loaded lever to secure pole piece on retaining electromagnet
Inventor: HORIO MOTOHIKO
IPC: G03B9/28
Filed: 1974-11-08
Abstract: The closing movement of the roller blind shutter is retarded for the selected exposure time by a second electromagnet and a pole piece coupled to the roller blind release lever. The pole piece has to be held securely onto the electromagnet, while when released any slack, or additional return force leads to exposure errors. The holder system provides a spring-loaded release lever pivoted on the pole piece securing lever and connected to the lever by a spring. The second spring holds the pole piece against the magnet, while the release lever is spring-loaded to pull the second spring from the pole piece lever at the end of the exposure time. The pole piece is then released off the magnet without any slack errors.

Title: Tuner for musical instruments - has electrical circuitry to produce reference impulse signals with displaced periods
Inventor: TAKEUCHI SHINJIRO
IPC: G10G7/02
Filed: 1975-06-05
Abstract: A tuner for musical instruments has a series of separate scannable indicator elements with n attached drive channels which may be controlled by a common gate switching combination. A tuning frequency produced by the instrument is thereby converted to an equivalent impulse by n reference impulses. As a result the reference inpulses are fed in an equivalent frequency from a common reference frequency generator. The phases are relatively displaced by 1/n full periods and have an impulse length of about 1/n of the total period length.
