Title: Chlorine-free aq. chlorine di:oxide soln. prepn. - by adding chlorite to water, acidifying, adding metal hydroxide and then carbonate
IPC: C01B11/02
Filed: 1977-07-08
Abstract: In Parent Patent, aq. ClO2 solns. are prepd. by dissolving 7-21 pts. wt. chlorite, 7.5-25-5 pts. wt. hypochlorite and 0.5-1.5 pts. wt. carbonate in 35-105 pts. wt. water, and mixing the aq. soln. obtd. with 7.5-22.5 pts. wt. dil. (in)organic acid, to set up pH 5-10. In this addn. aq. ClO2 solns. are prepd. by (a) adding 35-105 pts. wt. chlorite to 15-45 pts. wt. water; (b) acidifying the aq. sol(. obtd. by slowly adding 3-9 pts. wt. inorganic or organic acid; (c) mixing with 0.5-2.5 pts. wt. water-soluble metal hydroxide to set up pH 5-10 and (d) adding, with const. stirring, 0.5-1.5 pts. wt. carbonate to the aq. alkaline soln.. Process modification allows the prepn. of stable Cl-free ClO2 solns., which can be added safely to drinking-or bath-water. Water smell and taste are not affected and chloramine formation is prevented. The ClO2 soln. is stabilised by carbonate and requires no additional stabilisers, e.g. peroxides.

Title: Safety latch mechanism for press or stamping machine - has attached protective grid swivelling out to guard work location during tool power stroke
Inventor: LAHRMANN HELMUT
IPC: F16P3/04
Filed: 1977-07-23
Abstract: The safety device for pressure or stamping machines has the machine upper part movable against a lower part, with the workpiece placed between the two parts when they are open. To make the locating area for the workpiece safe during the closure of the machine parts, a swivelable protective grid is provided. The machine upper part opposite the lower part (14) is secured by a blocking device (13, 18) against a closure movement, and the protective grid (20) is coupled to the blocking device. A release movement imparted to the blocking device causes the protective grid to swivel out into a guard position around the tool area between the machine parts.
Patent DE-2733897-A1 (DE)
Inventor: TURNHEIM GEORG DR
IPC: F24S10/70
Filed: 1977-07-27
Abstract: A frame skeleton (1), in which on that side directed towards the sun there are installed rigid solar collector panels (2), is erected on the edge of an open-air swimming pool. Said panels are connected to a flow line (3) and to a return line (4). Heating-up is substantially more intensive than when the collectors are located horizontally, since the panels, due to their inclination, have a more favourable incident angle with respect to the solar rays. On that side directed away from the sun and on the gable sides, transparent panels (5) and/or doors (6) are arranged which serve to light up the swimming area since the solar collectors are opaque. The panels (5) and the gable sides with sliding doors consist of perspex in order to achieve a high degree of heat insulation, low weight and fracture prevention. As a result, the covering protects the open-air swimming pool from night-time radiation and prevents dirt from falling in. This covering does not have to be removed during the day. It does not prevent heating-up by solar radiation and requires no additional heating. <IMAGE>

Title: AVC for car radio - adjusts to ambient noise and speed using pulse signals from tachometer
Inventor: ROESCH FLORIAN
IPC: H03G3/32
Filed: 1978-07-28
Abstract: The a.v.c. increases the volume as the car's speed increases. The volume starts to be increased only when the vehicle's speed reaches a given threshold and continues until a max. speed threshold is reached. The signals proportional to speed are generated by a tachometer whose pulse frequency is proportional to speed. The volume is controlled at the 1.f. output circuit of the radio via a variable attenuator or amplifier. If the radio is stereophonic each channel has its own attenuator or amplifier.

Title: Reflector system for solar radiation installations - has double bank orthogonal or mirrors for reflecting radiation at any angle onto energy converter
Inventor: ROTH JUERGEN
IPC: F24S23/77
Filed: 1979-11-15
Abstract: The reflector system for gathering energy from the sun is simplified by constructing it from two mirror banks whose axes are vertical and orthogonal and each of which has the capability of being moved in one plane only. This enables a solar energy gathering system to be made without using large surface areas but in small commonly controlled sub-units, in contrast to the usual large swivelling mirrors, which move in two planes and are complicated and costly to construct. The independently controlled smaller reflectors can be angled to gather radiation from the sun and reflect it in the most efficient manner on to the receiving medium.
