Title: Two=part disposable safety razor with foam dispenser - has cam ring on neck of foam container that prevents cap unit and razor head from being pressed fully down until cap unit is turned to foam position with audible click
Inventor: FRICK HANS-RUEDI
IPC: B26B21/44
Filed: 1993-10-18
Abstract: The handgrip of the razor is a foam container (12) onto which is pushed a replaceable cap unit (22) with the razor head (26). Inside the cap unit are diametrically opposite fins (50,50a) which normally rest on the surface (68) of a cam ring (70) on the neck of the container (12). In the cam ring are two diametrically opposite slots (72) with radial beads (74) at the edge. When the cap unit (22) is turned relative to the container the webs (50a,50a) are forced over the beads with an audible click and enter the slots (72). Pressure on a thumb surface (80) can then force the cap unit downwards to open the container valve (18) and allow foam to be dispensed through the passage (46). USE/ADVANTAGE - Two-part disposable safety razor with foam dispenser gives greater convenience and security in use.

Patent DE-4345205-A1 (DE)
Title: Frame profile, in particular aluminium frame profile, for safety windows, doors and/or wall elements
Inventor: SOMMER HORST
IPC: E06B3/58
Filed: 1993-09-07
Abstract: The invention specifies a frame profile for windows, doors or wall elements with a filling, which frame profile has an outer side wall with a border section which, in the mounted state on the window, door or wall element, overlaps the filling on the outer side thereof, the outer side wall exhibiting, in the border section or in the vicinity thereof, a material weak point formed as a predetermined bending point or predetermined breaking point. If, in the event of a break-in attempt, a tool is positioned on the border section in order to lever the border section in the direction away from the filling, then the border section is deformed, as a result of the predetermined bending point, without releasing the filling. Thereafter, further leverage is made more difficult since, due to the deformation, there is no longer any favourable lever arm on the border section.

Title: Rocking chair with seat, floor support and elastic link
Inventor: ZIEGLER ALBERT
IPC: A47C3/026
Filed: 1994-01-08
Abstract: The link arrangement comprises a ball and socket or Cardan link (14) absorbing all the friction resulting from the seat's tilting, and protecting an elastic resetting element (18) from frictionally caused wear. The elastic link acts as a connection (4) between the foot and seat surface directly beneath the seat. The resetting drive exerts restoring forces between the first pressure surface (15a) fixed to the seat, and a second pressure surface (12a) at the top end of the foot, depending on the distance between the two pressure surfaces around a vertical axle (13a) through the pivot centre (14a). A pre-tensioning member (19) exerts adjustable pretensional force on the restoring element.

Title: Video recorder with additional recording facility for PAL-plus signals
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N7/00
Filed: 1994-08-10
Abstract: A helper colour signal (HT1) and a mix signal (M2) are set to a low frequency before recording. This frequency modulation is recorded by an image signal (BT), taking a light density signal (Y) into account and transferring it to another helper colour signal (HT2).  When the recording is played, a third helper colour carrier (HT3) resets the frequency to its normal level via a colour signal (Fo) in amplitude modulation.

Title: Hydraulic brake system with anti-lock and drive slip control device, especially for motor vehicles
Inventor: BERNHARDT WOLFGANG
IPC: B60T8/50
Filed: 1992-06-02
Abstract: The convenience of the brake system (1) is to be improved. The brake system (1) has a valve arrangement (19) for braking pressure modulation in the pressure accumulation, maintenance and release phases in a wheel brake (e.g. 8). The valve arrangement (19) has a restrictor (22) operative in the pressure accumulation phase. The restrictor (22) is circumvented by a by-pass line (27) in which there is a stop valve (28), which assumes its stop position (28b) in the pressure accumulation phases in anti-lock and/or drive slip control mode. Owing to the operation of the restrictor (22) in the pressure accumulation phase, the rate of pressure increase and hence the development of noise in the brake region are reduced. The brake system (1) is especially applicable to motor vehicles.
