Patent DE-2929799-A1 (DE)
Title: Marking points located ultrasonically for medical purposes - using mask enabling ultrasonic image and skin marker application
Inventor: THAELE MICHAEL DR
IPC: A61B8/00
Filed: 1979-07-23
Abstract: A method of marking points located ultrasonically for medical purposes, esp. radiology, gynaecology, urology etc., simplifies the marking procedure and makes it more reliable. A suitable point is first located using ultrasonic B imaging. The acoustic conditions are then varied in the region of the located point so as to mark the point. The marking is then transferred to the skin. The conditions are altered by placing a mask in the region of the point so as to vary the acoustic resistance. This enables the point to be marked on the ultrasonic image. The skin marking is applied by the mask after removal of the ultrasonic head. The mask has a small wall thickness and a round recess.

Title: Sewing machine folder attachment - has operating lever and drive on a mounting with easy dismantling and disconnection
Inventor: BAC CENGIZ
IPC: D05B35/08
Filed: 1979-07-25
Abstract: There is a mounting piece for the drive mechanism for the operating lever, which also carries the operating lever, which can be attached to or removed from the sewing machine. The control unit is powered separately from the sewing machine for controlling the drive, or is sepd. from it, which also generates an electrical impulse. The control unit also has a signal generator acting with the drive shaft for the needle's up and down movement. The design gives a sewing machine folding attachment which can be fixed simply and removed at will, and which can also be disconnected to allow normal sewing while the attachment is still in place.

Title: TV picture tube characters display - uses two-bit code and auxiliary deflection winding for small shifts at high speed
Inventor: DESERNO ROLF
IPC: G09G1/08
Filed: 1979-06-13
Abstract: The standard t.v.picture tube for character display has added to it a pair of auxiliary deflection coils. The auxiliary pair on the tube neck deflects the beam by small increments and at a high speed, lower redundancy being achieved by point-to-point shift, using a 2-bit code. For displaying closed curves, the code ensures advance, left or right step and stop, while double stop initiates a start of new coordinates set for further shift control.

Patent DE-2935231-A1 (DE)
Title: Desalination of salt water by solar energy - using inclined evaporator-collector with separate condenser having inclined cool surface to collect condensate (BR 10.3.81)
Inventor: GRUNDMANN EDGARD ING GRAD
IPC: C02F1/14
Filed: 1979-08-31
Abstract: Potable water is recovered from a crude water supply using a solar energy collector and a condenser. The collector has transparent panels and surfaces over which the water flows, generating vapour and establishing a recirculation. The hot water recirculates from a tank above which is a vapour space. Over the vapour space is an inclined surface, cooled by a crude water stream. Condensate runs down this surface and is collected into a separate tank. The system prepares potable sweet water from contaminated or saline crude water esp. sea water. The process does not require a large constructional and financial outlay and separation of the evaporation and condensation sections means that both can be optimised in design.

Title: Coin stacker with ejector opening - has pivoted lever wiper blocking path when storage is full and diverting further coins
Inventor: RUZIC HUGO ING GRAD
IPC: G07F9/04
Filed: 1979-09-15
Abstract: A coin stacker has a by-pass for continuously-arriving coins preventing blockage of the coin storage. When the latter is full further coins are diverted. A wiper ensures that coins passing through the stacker are kept a certain distance apart w.r.t. time. The wiper (6) is installed in the storage (10) and is pivoted by coins (2,3,4) sliding through it. The end of a lever arm (11) protruding along the direction of coins travel lies, in its rest position, on the coinage sliding path (1) under the effect of pressure force. The end of the other lever arm (12) is positioned opposite the coinage path (1) and in its pivoted state operates against it to block the storage. Subsequently arriving coins are diverted through an ejector opening (9). The axis of rotation (7) of the wiper (6) is on the wall (8) facing the coinage path (1).

Patent DE-2944438-A1 (DE)
Title: Heat insulating panel - made of sprayed polyurethane with or without surface pattern
Inventor: VERMEULEN JOHANNES
IPC: E04B1/80
Filed: 1979-11-03
Abstract: Insulating panels, for example for the heat insulation of the inside walls of rooms in buildings, are made of plastic, pref polyurethane, sprayed on an endless belt to produce a web with a plane or patterned surface. Surface skins on both sides form a boundary layer, one of which is bonded to the wall whilst the other receives a wallpaper unless it carries a surface pattern, for example simulating a brick wall. The boundary layers prevent damage to the insulating panel and wallpaper on it by contact e.g. with corners of furniture. Polyurethane is easy to cut and forms good bonds with walls or wallpaper.

Title: Converter for constant speed rotation into reciprocation - has reciprocating part moving over selectable path at constant speed, driven by connecting rod
Inventor: PLUNTKE RUDOLF
IPC: F16H19/06
Filed: 1980-01-26
Abstract: The mechanism is intended for converting a continuous constant-speed rotary motion into a reciprocating motion, (e.g. of a carriage (5). At the ends of each stroke the speed increases and decreases sinusoidally between zero and maximum. Once the maximum speed (Vmax) is reached, this remains constant over a predetermined part of the full stroke. The carriage may be driven by a connecting rod (4) linked to an endless chain (2) around two chain wheels (1,3), of which one is driven at constant speed. It may, alternatively, be driven by a constant speed pinion meshing with a totally enclosed endless tooth rack with two parallel rack portions.

Title: Moisturising component for cosmetics - prepd. from skim milk by simultaneous action of protease and lactic acid bacteria
Inventor: LEE BYUNG SOON
IPC: A61K8/98

Abstract: Skim milk is simultaneously subjected to fermentation by lactic acid bacteria and the action of aprotease. at 35-40 deg.C for 12-48 hrs, then heated to a temp. and for a time sufficient to sterilise it and inactivate the enzyme. The process is quicker, simpler and cheaper than the prior art process in which fermentation and protease treatment were carried out separately with heat treatment steps after each. The decomposition of caslin by the protease accelerates the growth of the bacteria. Suitable bacteria include L. acidophilus, L. bulgaricus, L. Casei and Str. thermophilus.

Title: Shutter and aperture camera exposure control - has shift register connected to reset circuit and via adder to comparator output and gated stage input
Inventor: HENTSCHEL HANS-MICHAEL DIPL IN
IPC: G03B7/097
Filed: 1980-09-02
Abstract: Automatic exposure circuitry for a camera, e.g. s.l.r. type, has a program for both aperture and shutter speed settings. The circuitry uses 9 aperture settings and 16 shutter speed settings which also have 8 fine adjustments. The circuitry uses 7 bit D/A conversion. Max high speed flexibility is achieved with a less than 6 volt rail, possibly on 3 volts, to drive the logic circuitry. The circuitry measures subject brightness and incorporates film speed for its comparator-based operation. The digital computer stage comprises a shift register connected via an adder to the output of the comparator and input of a gated stage. The shift register is also connected to the reset circuitry, for most significant bit signalling. An adder is also connected to shift register and the reset stage and is used as a difference counter between the shift register held information and the programmed information in the programme gate stage and the aperture counter. The shift register and counter control have an output to the aperture adjust and the D/A converter.
