Title: Mass-produced coat stand for upright walls - has mounting for detachable picture holder for decoration when unused
Inventor: HILBERT THOMAS
IPC: A47G25/06
Filed: 1975-01-31
Abstract: The coat stand is provided with a fastening section for attachment to upright walls and at the front forms a head or top section (3) which is provided on its front side facing the user with a mounting for the detachable fixing of a picture holder (8). This means that the user can provide the coat stand with a picture or the like of his choice so that when the stand is not in use it represents a decorative object. Since this picture holder also conceals the fastening point to the wall, easier cheaper fasteners can be used which are mounted from the front of the stand. The mounting for the picture holder may be designed as snap connection so that the holder can be readily exchanged.

Title: Minced sausage meat - with hops, hopasparagus ans asparagus replacing synthetic seasoning for improved taste
Inventor: BOESL JOSEF
IPC: A23L13/40
Filed: 1975-05-21
Abstract: Sausages and meat products with a novel taste can be produced by adding to the meat as seasoning natural spices such as hops or asparagus.

Title: Ventilating system for travelling crane cabs - has air supply blow air and exhaust system for gas removal
Inventor: CULLEN PATRICK FRANCIS
IPC: B66C13/52
Filed: 1975-07-04
Abstract: The ventilating, system is for travelling fume hoods and cabs of travelling vehicles such as cranes wherein an air supply or exhaust unit is located outside the area in which the hood or vehicle operates. The air supply or exhaust unit blows air to or exhausts gases through a duct having an elongated slot therein. In the case of the travelling vehicle an air scoop, receiving air from the slot and delivering it to the crane cab, travels back and forth in the slot as the crane travels and a special sealing device keeps the slot sealed in front of an behind the air scoop. The procedure is reversed when gases are being exhausted from a travelling fume hood or other travelling exhaust system.
Patent DE-2543978-A1 (DE)
Title: Simultaneous crease proofing and water proofing of cellulosic fabrics - by impregnation with an aminoplast resin and a polysiloxane in a non solvent polar solvent
Inventor: DEINER HANS
IPC: D06M23/10
Filed: 1975-10-02
Abstract: The parent specification describes a process for the simultaneous creaseproofing and waterproofing of cellulosic textiles. In this, the wet fabric is treated in a bath contg. 5-60 g/l of an organic solvent soluble ehterified aminoplast resin, 5-50 g/l of a hydrogen alkyl polysiloxane, at least 25 ml/l of a polar solvent and at least 1.5 g/l of a dialkyl tin acylate dissolved in a nonpolar water insoluble solvent. Excess of the bath is then removed and the fabric dried to condense the resin. In the present patent, the process is carried out in the absence of polar solvents. Prevents the polar solvent becoming fixed to the textile as in prior art process, which causes a reduction in the polar solvent and enrichment in foreign solvents in the treatment bath, and makes difficult the attainment of an even finishing effect. Suitable solvent soluble amino resisn are dimethylolethyleneurea, dimethylolalkyl (1-5C)-carbamate and hexamethylolmelamineS, highly ehterified with a low alcohol. The nonpolar solvents used may be e.g. hydrocarbons or halogenated hydrocarbons as mentioned in the parent specification. After impregnation, e.g. by foularding, the treated fabric is dried at 80-100 degrees C and then heated at 120-160 degrees C to condense the resin. In an esample, 40g methylated dimethylolethyleneurea, 20g methylhydrogenpolysiloxane and tetrachloroethylene to 11 were mixed with 8g dibutyltindilaurate to form a treatment bath used to impregnate cotton poplin. After drying and heating for 4 mins. at 140 degrees C the fabric had good crease resistance and water repellency.

Title: Thermostat controlling central heating boiler - has setting corrected at every limit signal from room thermostat
Inventor: BURISCH ALFRED
IPC: F24H9/20
Filed: 1976-08-17
Abstract: The central heating boiler is controller directly from the room thermostat, and the inertia of the system causes temperature oscillations. These oscillations can be avoided by using a regulated mixture of hot and cold water, but a fixed hot-water temp. high enough for cold days is too high for warmer days. A motor is used to correct the setting of the boiler thermostat each time a limit signal is received from a room thermostat, thus automatically adjusting the boiler's target temperature to the prevailing need.
