Title: Aluminium fluoride/complex fluoride prodn - economic method for high-purity products
Inventor: BELSKY MILAN
IPC: C01F7/50
Filed: 1971-03-20
Abstract: Aluminium fluoride is prepd. by treating aq. acid aluminium chloride with stoichiometric quantity of hydrofluosilicic acid at 100-105 degrees C: 2AlCl3 + H2SiF6 + 2H2O right arrow SiO2 + 2AlF3 + 6HCl Silicic acis is in easily filtered form and hence completely removed. Filtrate-soln. is either concd. to deposit AlF3 or cooled to 20-30 degrees C and treated with NaF to produce sodium aluminium fluorides. Exact compsn. of complex depends on Na:Al ratio e.g., if 3, cpd. is cryolite 3NaF . AlF3. Very pure fluorides are formed in excellent yield. The SiO2 and HCl produced in process can be used to form further AlCl3 for a highly efficient cyclic operation.

Title: Thermal conducting wall for plates - has several fine channels formed on the surface crossed by second set of similar channels
Inventor: KAKIZAKI KIMIO
IPC: B23P17/00
Filed: 1974-02-06
Abstract: The heat-conducting surface is formed by successive knurling, cutting and brushing. In the first stage a knurled wheel produces a fine spiral of grooves lying close to one another on the surface of the e.g. copper tube. The spirals lie at approx. 45 deg. to the tube's axis and form the 'first' set of grooves being around 0.05 to 0.3 mm deep and separated from one another by less than 1mm. The 'second' set of grooves are created by deforming the surface using a groove cutter and produce a number of fine ribs which are separated from one another by this second groove set. This second set cross the first set at an angle of about 90 deg., are approx. 0.76mm deep and together with the first set create ribs approx. 0.2mm thick projecting 0.58mm from the surface of the copper tube. The wire brush disc treatment tends to form a banded surface on the end edges of the ribs which are deformed laterally and thinned without cutting them off by this.

Title: Drum for wet chemical or electrochemical treatments - contg central perforated tube for insertion of anode or spray pipe
Inventor: SPELSBERG HERBERT
IPC: C25D17/20
Filed: 1974-02-15
Abstract: The device with several treatment stations is for the chemical and/or electrochemical bath treatment of mass-produced parts, in an immersion drum with a coaxial central tube, esp. for electroplating. On one side of the drum is an open, perforated, central tube which functions as a feed piep for energy or treatment media in the various handling stations. The pref. drum uses a side channel from which an anode or a perforated pipe (e.g. for the injection of water) can be inserted into the central tube; alternatively, a hot-air pipe can be connected to the central tube. The ability to insert an anode along the axis of the drum results in extremely uniform distribution of the electric current, rinsing water, hot air for drying etc.

Title: Adjustable guiding and sealing device - has elastic ring fitted inside guiding and sealing rings with adjusting screw
Inventor: HUNGER WALTER
IPC: F16J9/08
Filed: 1974-06-26
Abstract: The design is for pistons and piston rods and has at least two guide rings and at least one intermediate sealing ring into its working position.

Title: Rapid starting static converter - particularly for standby supplies provides full power with minimum start up time and uses batteries for energy store
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02M7/517
Filed: 1974-09-27
Abstract: The static converter circuit provides its full output power with a correct phase relationship to the supply which it will be replacing in a very short time. During normal supply periods energy is stored to be fed into the load system, and when priming or firing signals are allowed through to the inverter by interruption of the normal supply, the inverter is supplied by some standby d.c. source such as batteries providing both polarities. This ensures that the correct polarity is available at the instant of switching. Switching is by electromechanical relays, thyristors or triacs (Tr1, Tr2), the switching operation being synchronised from sensors in the switching network.

Title: Fault indicator automatically indicating rare faults in TV receiver - uses photodetector on TV screen to detect intensity changes
Inventor: EGBERTS EKKEHARD
IPC: H04N17/04
Filed: 1974-10-12
Abstract: The fault indicator automatically indicates rare faults in television receivers by using a photodetector (7) to scan a given area of the screen of the receiver and to detect any irregularities in that region. The photodetector is coupled to a circuit (11) that triggers an alarm (16, 18) when the monitored part of the picture changes in intensity. The advantage of this fault indication lies in its being fully automatic and therefore does not require the presence of test personnel constantly watching the screen in the hope of detecting a very infrequent fault.

Title: Car seat with headrest and built in mini speakers - directs noise to individual ears avoiding interference to other passengers
Inventor: EISSMANN VOLKHARD
IPC: B60R11/02
Filed: 1974-10-16
Abstract: The car seat (10) is preferably provided with an integral head and neck support (11) wherein speakers (16) of a radio and/or record player are mounted near the top to direct the sound to the cars without screening off all surrounding noise, e.g. sound of traffic etc. In this way the nearness of the speakers to the ears means that the sound of the radio etc. can be kept relatively low so that other passengers are not disturbed. However extraneous noise which is essential to the quick reflexes of the driver is not completely shut-out. The speaker is preferably fastened so that it can be adjusted along the head rest, and it is preferable if one speaker is mounted either side of the head rest (11) on an arm (14) which is displaceably mounted at bearing points (20) on or in the headrest.
