Patent DE-2534356-A1 (DE)
Title: Furnace tubes for hydrocarbon processing - with internal flutes to prevent coke deposition and premature corrosion
Inventor: WISKEN ADOLF HERMANN DIPL PHYS
IPC: C10G9/20
Filed: 1975-08-01
Abstract: In processing furnaces for hydrocarbons (for mineral oil distillation and for thermal cracking) the tubes which carry the hydrocarbons and are heated from the outside are equipped inside with facilities to improve the heat transfer conditions on the side towards the firebox. These are pref. longitudinal corrugations which increase the inside surface area. This prevents the deposition of coke which leads to rapid corrosion. It is a less expensive method than using corrosion-resistant high-alloy steel, or designing the furnaces with longer tube spacing and lower or more uniform thermal loading.

Title: Limb treatment bath with air jets - has raised support for limb and air:jet plate perforated with holes of three different kinds
Inventor: BAUMANN LUDWIG
IPC: A61H33/02
Filed: 1975-10-22
Abstract: The limb is treated in a bath of water across the bottom of which is a performed plate. Air is forced through the plate, forming jets that stimulate the limb. The limb will rest at some distance above the perforated plate, supported on a wire grid, whose height is adjustable, and which may also be swayed rhythmically, by the limb itself, or independently. The perforated plate has holes of three different kinds; normal, medium-sized holes; holes of 1 mm diameter to generate needle-thin high-pressure jets; and holes of 1-2 mm diameter through which strong jets can be directed at particular areas.

Title: Grafting device for plants - has U-shaped pincers head support which has two parallel U-shanks with straight guide for slide
Inventor: WAHLER EUGEN
IPC: A01G1/06
Filed: 1976-01-22
Abstract: The grafting device is for plants especially for first bushes and shrubs where there is a support, on which a prismatic support is held, which accepts the graft and/or the bush to be grafted. A slide can move along a straight guide on the support and on the slide is fixed a leaf-shaped forming blade in the form of an omega. The slide is coupled with an operating device while a stripper is held on the support spaced from the arching of the form blade. Specifically the support is in the form of a U-shaped stiff pincers head (10) whose two parallel U-shanks (11, 12) have the straight guide (29, 25) for the slide (26). One U-shank (11) at the free shank end has a cross-strut (19) which is parallel to the U-strut forming the base of the U.
Patent DE-2604167-A1 (DE)
Title: Pressure control pneumatic vent valve - with disc shaped valve body and seat cutout to obviate vibration noises
Inventor: HOENIG HANS
IPC: F16K17/04
Filed: 1976-02-04
Abstract: Normally, when a vent valve lifts, a large valve area is instantly given free, which causes a large pressure drop. This in turn causes the valve to close immediately. Opening and closing occurs, fast causing a buzzing noise. To avoid this, the valve seat (16) is provided with small cut-outs along its circumference. The cut-outs are so shallow that they are filled by the elastomer diaphragm plate which is pressed against the valve seat. When the valve lifts, the small area represented by the shallow cut-outs is first given free, after which the diaphragm lifts from the valve seat and a more gradual increase of valve area is achieved.

Title: Single pipe central heating radiator fitting - has oblong section vertical pipe welded tangentially to horizontal distributing pipe
Inventor: STEINBEISSER GEORG DIPL ING
IPC: F24H9/12
Filed: 1976-06-04
Abstract: The radiator connecting fitting for single pipe installations consists of a length of oblong section vertical pipe (6) blanked-off at the top and provided with a hole (8) on the broad surface to which threaded oipe connection (7) is welded. The other end of the oblong section pipe is welded tangentially to the horizontal distributing pipe (2) in such a manner that at the penetration of the two pipes an indentation (1) is created. The indentation is produced by partly weakening the pipe wall and then bulging in the weakened part of the pipe wall. This operation creates a flow deflecting surface within the distributing pipe which diverts part of the flow into the vertical oblong section pipe and then into the radiator. With flow in opposite direction this deflecting surface acts as a guide surface where the return from the radiator joins the main flow.

Title: Deep freezing tomatoes - involves splitting skins by cooling then heating to about 30 degrees C to facilitate skin removal
Inventor: TENUTA ANTONIO
IPC: A23B7/04
Filed: 1977-08-03
Abstract: Well-ripened tomatoes are prepd. for skin removal by splitting the skin at atmospheric pressure using a temp. gradient of 60-65 degrees C. This temp. gradient is the difference between the initial temp. of the tomatoes and the skin splitting temp. the gradient being other than the usual one of ambient to boiling water temp. The pref. temp. gradient is obtd. starting from -30 degrees C and finishing at 30-35 degrees C. The process is applied to deep-freezing whole or cut up tomatoes. The process enables much less energy to be used in skinning the tomatoes, which can make the deep-freezing economic compared with canning. By deep freezing the taste properties are unaltered, preservative are not required and canning and transport costs are reduced. Prod. may be packaged in polyethylene bags.
