Title: Tooth pastes contg magnesium monofluorophosphate - as fluorinating component and use in pressure gas packaging
Inventor: FOERG FRANZ DIPL CHEM DR
IPC: A61Q11/00
Filed: 1975-06-16
Abstract: Tooth-paste contains Mg monofluorophosphate (I), as F-component in the liquid phase. Content of (I) is 0.1-5 (0.5-2.5) wt.% calculated as the anhydrous salt, w.r.t. total tooth-paste compsn. Other components of tooth-paste are those in standard use for filling tooth-paste tubes. Use of (I) prevents (i) syneresis, (ii) increased drying out of paste in valve system and (iii) premature failure of the tooth-paste press. gas pack. Tooth-paste contg. (I) requires shorter relaxation times, after pressing out of tube onto brush, than a corresponding tooth-paste contg. NaF or Na monofluorophosphate in place of (I). Propellent gases may be pressed in up to 9 atmos. over-press. Pref. tooth-paste viscosity under normal press. is 400000-6000000 (450000-550000) cP. In an example, substitution of 2.6 wt.% (I) by (b) 0.22% Na monofluorophosphate or (c) 0.76% Na, increased viscosity of tooth-paste, stored 7 days under 7 atmos. over-pressure from 550 to (b) 650 and (c) 830 x 103 cP.

Title: Miniature tape recorder control - with separate control knob and selector switch for record and playback
Inventor: WIES KARL
IPC: G11B15/10
Filed: 1975-08-27
Abstract: In a miniature magnetic tape recorder for dictation or in hand microphones with a remote control function, a separate element for RECORD and PLAYBACK ensures that an inadvertent setting to RECORD is eliminated.

Title: Rapid fitting ice grips for tyre - with two pairs of hoops and with additional hoops clipped to main pairs
Inventor: LAUCHS STEFAN
IPC: B60C27/04
Filed: 1975-09-05
Abstract: The ice grip hoops for the tyre comprise four sets of hoops which are clipped over the tyre at right angles to each other, and which are tensioned towards the middle of the wheel by rack and pinion drives and a coil spring. To provide extra grip additional hoops (27) are clipped to at least two of the main hoops. The additional hoops have angled sections which clip over the tyre tread at spacing between the main hoops. The additional hoops are simple to fit, with their attachment points being nearer the wheel middle than the edge. They provide a smoother grip so that the wheel can be driven at speed over snow. This enables the driver to drive on after fitting the hoops to retrieves his vehicle from soft snow.
