Title: Machine tool for fine grooves in arc profile - is rotated reciprocally by swing unit hydrostatically supported and has central plunger as feed piston
Inventor: GREUEL ARMIN DIPL ING
IPC: B24B35/00
Filed: 1976-12-17
Abstract: In fine machining of grooves of arc-shaped profile, the machining tool is pressed against the turning workpiece and executes a periodically reciprocating rotary motion about an axis which lies in the mid point of the arc-shaped profile. The swing unit is hydrostatically supported in the machine frame and the tool feed is hydraulic or pneumatic. The feed piston (4) in the form of a control plunger, released a switch line supplied by a separate pressure circuit when the tool is finished. This switch line (15) controls a pressure switch which switches off the pressure generator. Air can be used as the pressure medium and these may be a second piston (5) to lift the tool from the workpiece.

Title: Circuit for east-west cushion correction in TV set - includes capacitor whose variable capacitance depends on correction voltage frequency
Inventor: POLLAK ALFRED
IPC: H04N3/233
Filed: 1977-05-31
Abstract: The line deflection current in the deflecting coils (8) is modulated in amplitude at vertical frequency by the correction circuit (10) in such manner that the current amplitude at the upper and lower edges of the picture is reduced and vertical lines at the left and right edges of the picture are straight lines. However, vertical lines adjacent the picture centre still exhibit cusion error, and in order to overcome this defect the condenser (11) is one in which with increasing voltage across it its capacity decreases with the frequency of the east-west cushion correction voltage. In a modification, the correction circuit (10) is replaced by a capacitor which serves as a short-circuit for the line frequency, land a parabolic correcting voltage of vertical frequency is applied to the capacitor (11), whereby to correct the whole of the east-west cushion error.

Title: Milking machine washing plant operating under vacuum - supplies plugs of wash water rapidly through ring main
Inventor: ICKING FRIEDRICH DIPL ING
IPC: B67D1/07
Filed: 1977-06-16
Abstract: The parent patent describes an appts. for cleaning and sterilising the milk ducts and piping of milking machines. A wash water ring main, under sub-atmospheric pressure, is connected to the milking plant and communicates with a balancer tank contg., in its upper part, a feed tank for sterilising and/or washing mixt. This feed tank is connected by a line to the sub-atmospheric ring main leaving the outlet of the balancer tank and also by a branch to the fresh water inlet. The feed tank can be cut off from the ring main. The balance tank contains a water level regulator, set to a level between the overflow and the outlet. In the addn. the outlet fromt he balancer tank comprises a horizontal leg and vertical leg of an L-shaped pipe, the vetical leg of which extends up to the level at which the level controller closes the water supply. The flow cross-section of this L-shaped pipe is equal to that of the outlet; there is also a small overflow aperture in the region of the horizontal leg of this pipe esp. in the wall of the vertical leg. During the sub-atmospheric cleaning operation, successive liquid plugs are produced in the ring main, and pass under the effect of the vacuum rapidly through the system to effect the cleaning procedure.

Title: Solar heat collector - with cavities in channels for circulating air, esp. for use as part of a house roof
Inventor: HEEL JOANNES MARIE VAN
IPC: F24S10/70
Filed: 1977-10-06
Abstract: A solar heat collector for transmission of radiated heat to a fluid stream such as air, is assembled from several parallel metal U-sections which form by their webs a continuous surface for the incident sun's rays.

Abstract: New agents for inhibiting or regulating nitrification of ammonium nitrogen in culture media contain as active ingredient >=1-acyl-pyrazole of formula (I). In (I), R' and R3 are H, halogen, opt. substd. alkyl or aryl, and R2 is H, halogen, alkyl or NO2. When R' and/or R3 is/are H or alkyl, then R4 is opt. substd. alkyl, alkenyl, aryl, opt. substd. aryloxy, alkylmercapto or arylamino and X is O or S. When R' and/or R3 is/are halogen or aryl, then R4 is opt. substd. alkyl, alkenyl, aryl, opt. substd. alkoxy, aryloxy, alkylmercapto, arylmercapto, or amino opt. substd. by alkyl and/or aryl, and X is O or S.

Used to prevent nitrification of ammonium nitrogen (esp. that added in fertilisers) in order to minimise loss of nitrogen by leaching out of the more soluble nitrate nitrogen formed by the nitrification process. This gives improved utilisation of nitrogen added in fertillisers and reduces nitrate pollution of ground waters. (I) have adequate water-solubility and are non-volatile. Their stability ensures prolonged action. Activity is evident with low concens. of (I).

Title: Roof tiles for solar air heating system - with three inlet-outlet types for bottom, intermediate and top rows of tiles
Inventor: WIENEKE FRANZ PROF DR ING
IPC: F24J2/04
Filed: 1978-11-09
Abstract: Solar heat collector system for air heating consists of roof tiles with conventional dimensions, each including an absorber area and a transparent cover plate. The air enters through the slot at the bottom edge of the lowest row of tiles (tile type A) and passes from an elbow at the top edge into the hole at the bottom of the next higher tile. The intermediate tiles (type B) also have an exit elbow at the top edge. The top row of tiles (type C) have in addition to a bottom inlet, a bottom outlet for the hot air which is joined to a hot air system, or to a heat exchanger for the heating of water, or to a heat pump. The cold air is thus successively heated by contact with the absorber areas and the air leaving the top line of roof tiles has a higher temp. difference.
