Title: Maize harvester with cob remover and stalk chopper - consists of rollers between picker implement and cutter blades, with drive axle situated to one side
Inventor: MARKGRAF JUN KARL
IPC: A01D45/02
Filed: 1975-11-03
Abstract: The maize-harvester has plates (3) which shake the plant's stalk (1) downwards so as to remove the cobs (2). A chopper has a drive-axle (4) which is roughly vertical, and a horizontal chopper with blades (5). Between the plates (3) and the choppers (4, 5) are rollers (6, 7) forming a conveyor for the stalks (1). The rollers (6, 7) pull the stalks (1) almost vertically downwards through the gap between the plates (3), and pull them into the operating-range of the chopper blades (5), where the stalk (1) is chopped up at the same time as the cobs (2) are removed. the axles of the rollers point in the direction of travel. The axle (4) of the chopper is positioned to one side. The blades (5) are positioned at a relatively high position above the ground. The machine can incorporate a number of a harvester-implements to deal with several maize rows at a time. If the axle (4) is positioned close to the stalk's conveyor-plant the blades (5) have a longer operating range.

Title: Air line lubricating head with circulating oil flow - has air flow sensor for proportional oil injection through venturi nozzle
Inventor: HOFFMAN ROBERT KENDALL
IPC: F16N7/34
Filed: 1975-12-01
Abstract: An oiler unit for the lubrication of a compressed air line has an oil reservoir (10) attached to the under side of a mixer head. Part of the compressed air is used to pressurize the air space in the oil reservoir, whilst some of the compressed air creates an under pressure as it flows through a venturi nozzle (40). Oil, thus forced through a measuring and vapourizing jet, is then mixed with the main air flow inside the oiler unit. Surplus oil forms drops so that due to gravity they return to the oil reservoir along the deflector duct (30). The amount of oil injected into the air line is proportional to the volume of the air flow.

The secondary winding output is connected to a trip, possibly through an amplifier and an evaluation circuit. The trip operates a latch operating contacts in the mains cables. Magnetic bias winding (9,10) generates a magnetisation with a d.c. and an a.c. component, so that in a state free from leakages magnetic flux varies between saturation and a value below remanence induction. The windings (9,10) are connected with a generator whose windings are coupled to the other circuit links and to the trip circuit.

Title: Regenerative heat exchanger for ventilating systems - has drum constructed of different materials for heat and moisture transfer
Inventor: HOENMANN WINFRIED DR ING
IPC: F24F3/14
Filed: 1976-04-05
Abstract: The regenerator has a drum with many air passages within a thermal storage core. The drum rotates on a central shaft with half its cross section in the supply air stream and half in the exhaust air stream. Heat and mosture are thus transfered by means of the drum from one stream to the other. The drum is constructed of a sheet (23) which is wound in a spiral with the successive layers kept apart from each other by a corrugated strip (22) wound spirally with the sheet. The flat sheet (23) has hygroscopic properties for moisture exchange and the corrugated strip (22) has thermal characteristics for sensible heat exchange. This enables latent and sensible heat exchange to be controlled independently of each other.
Patent DE-2620772-A1 (DE)
Title: Width stretching roller for sheet material - has curvature developing in sinus form to compensate unevenness
IPC: B29C53/04
Filed: 1976-05-11
Abstract: A width holding arrangement for handling sheet material consists of a stretching cylinder formed by a stationary central shaft supporting a flexible mantle or a number of tubular sleeves coupled together. The shaft is carried in pivoting bearings and thrusters act on the shaft ends, applying turning moments in the same or contrary direction round the corresponding bearings. It is thus possible to impart a curvature running in sinus form to the stretching cylinder. The arrangement is esp. applicable to weft straightening in piece goods processing since its sinusoid curvature allows it to deal with irregularities altering constantly.

Pref. the height of the conveyor throw above the composting area is variable to give optimum sized pieces throughout the heap. The composting area may also be provided with air channels to allow natural or artificial passage of air form below to assist rotting and moisture release. Process gives good composting of domestic and municipal waste in compost heaps having optimum aeration and dewatering properties.

Title: Child protective window fall safety device - comprises spring line hung across on hooks to prevent opening (OE 15.8.76)
Inventor: BUCHHALKA GEB EISLER FRANZISKA
IPC: E06B7/28
Filed: 1976-09-20
Abstract: The safety device is for the prevention of accidental falls from windows, esp where children are likely to climb up, open the window and lose their balance. At the same time it does not impede window cleaning, or detract from the appearance of the building. A tension spring (10), pref a steel helical spring, is stretched across the line of the window, on the inside, and at an interval above the sill (1). On each side this is detachably hung in to a hook (6, 7), preventing the window from being opened when it is suspended in this way. There are pref hooks at both ends, about 1m above the sill, fixed to the encompassing frame or its cladding, and the spring can have end eye loops (9) for hanging into the hooks, which are bent back to leave only a narrow insertion opening.

Title: Safety insert for tubeless tyre - high pressure air reservoir inside wheel rim and connected to tyre interior by pressure control valve
Inventor: HASSE ROLAND
IPC: B60C23/16
Filed: 1976-11-11
Abstract: A high pressure air reservoir is fitted inside the wheel rim, and inside the tubeless tyre. It is filled via a stub set through a hole in the wheel rim, and is connected to the inside of the tyre by a pressure control valve. The capacity of the reservoir is sufficient to replace air leaked slowly from the tyre and ensure a safe tyre operation. The pressure control valve has a membrane operation with a simple assembly unaffected by the rotation of the wheel. If the tyre suffers a large leak, the air from the reservoir slows the rate of air loss and allows the driver to stop the vehicle safely.

Title: Detachable wrist strap for safety ski stick - has anchor bracket located by integral leaf spring with hooked end deflected by excessive pulling force
Inventor: LENHART KLAUS
IPC: A63C11/22
Filed: 1976-12-15
Abstract: The safety ski stick has a leather or plastics strap which forms a closed loop (25), (26) that is located around the wrist of the skier. The two ends of the strap are attached to a bracket (29) which is provided with an anchor wedge (32) at its location end. When the ski stick is in normal use, a leaf spring (15), located inside the top end of the ski stick retains the anchor bracket of the wrist strap in its location. An excessive pulling force on the wrist strap (25) causes the hooked end of the leaf spring (18) to be deflected, thus releasing the strap from the stick. By pushing the bracket wedge (32) into its location, the ski stick is reusable again.
