Title: Vacuum sealed jar opener - has lever with roller which is used to apply three point load to relieve vacuum inside jar
Inventor: TAUBMANN HANS
IPC: B67B7/20
Filed: 1974-10-23
Abstract: Lid opener for vacuum sealed jars in the food industry overcomes the conventional friction approach and consequent slipping between hand and lid by applying load at three points to the lid and thus partially raising it. The result is that pressure balances between the inside of the jar and outside atmosphere, so that once this has been effected the lid can easily be twisted off. Preferably, the opener is made up of a lever with a handle at one end and the roller at the other arranged so that the hook end of the lever grasps under the lid and the roller acts on the top of the lid as an abutment for the load applied by the lever. Though not specified, the roller should form a two point thrust bearing on the lid so as to spread the load and improved the pressure relieving action afforded by the opener lever.

Title: Thermoplastic membrane bonded to moving coil of dynamic transducer - by coating with heat activated adhesive and centring with winding mandrel
Inventor: BRADL ERNST
IPC: H04R31/00
Filed: 1975-09-17
Abstract: The membrane is adhesively bonded to a self-supporting moving coil and pot magnet casing of a dynamic transducer serving for centring. The moving coil, which is located after the winding operation on an associated winding mandrel, is adapted to be stripped off by means of a sleeve. The surface of the membrane facing the moving coil and the bearing surface of the pot magnet casing is (partly) coated with a heat-reactivable hot-adhesive. The moving coil is pressed, by means of a stripping-off sleeve, onto the membrane which has been placed into a glueing device provided with a heatable ring, and so bonded together by brief heating. The centring of the winding mandrel with the membrane may be ensured by the glueing device. The membrane may then be glued, in similar manner but in a separate glueing devide to the pot magnet No great glueing pressures are required for the process, so that it is safely applicable to the handling of delicate components.

Title: Colour indicator dosimeter for ionising radiation - contains mixt. of dyes, having different decolouration values on irradiation, in polymeric matrix
Inventor: PANTSCHENKOW GEORGY MITROFANOW
IPC: G01T1/04
Filed: 1975-10-09
Abstract: A colour indicator-dosimeter of ionising radiation includes 70-100 wt. pts. thermoplastic polymer, 10-40 wt. pts. plasticiser, 0.5-3 wt. pts. stabiliser, and two dyes compatible with the polymer. One dye (I) has a max. absorption in the range 450 - 590 nm and a G value of decolourisation in the polymer of 0.05-1. molecule/100 eV; it is present in the compsn. in amt. 0.007-0.01 wt. pts. The other dye (II) has a max. absorption in the range 600-720 nm and a G value of decolourisation of 0.15-1.5 molecule/100 eV; this dye is present in the compsn. in amt. 0.015-0.03 wt. pts. Unlike known dosimeters, the present compsn. does not use acid-sensitive dyes and thus does not require a protective coating and allows industrial purity grade materials to be used. It is not sensitive to light, so that its colour is stable with time, after irradiation, for >=12 months. Further, the contrast colour change on irradiation (blue right arrow red) enables the radiation dose to be determined under any irradiation conditions. Typically, dose rates within the range 0.5 x 106 to 3.5x107 rads can be measured visually to within 25-30% accuracy and objectively to within 15-20% accuracy.

Title: Eliminating explosion danger in alkali-chloride cell - by flushing cell with inert gas during maintenance pauses to remove hydrogen
Inventor: KLOTZ HELMUT DR
IPC: C25B1/36
Filed: 1976-03-19
Abstract: Danger of explosion in alkali-chloride electrolysis cell of the amalgam type, when short-circuited for maintenance, is eliminated by flushing the gas space of the cell with an inert gas, pref. Cl2. During pauses, H2 is evolved in an alkali-chloride cell of the amalgam type on the graphite anode or esp. on an activated valve metal anode. When the H2 content in the chlorine filling the gas space of the cell exceeds 4% there arises danger of an explosion. This can be eliminated by flushing the cell with Cl2 (pref.), N2 or even air. The flushing can be started automatically by the cell's short-circuiter. It should last until the amalgam in the cell is exhausted or replaced by fresh mercury.
