Patent DE-2626048-A1 (DE)
Title: Lubrication system for ship screw - with separate drainage ducts for oil and water leaks(NL110177)
Inventor: WILKINSON SAMUEL CLIFFORD WALT
IPC: B63H23/32
Filed: 1976-06-10
Abstract: The ship's propeller shaft (2) passes out of the hull (3) via a bearing (12) lubricated by a gravity fed oil tank (17). The outside of the hull is protected by a double lipped seal (8, 9) which has a rising drainage duct (16) between the lips to lead any oil leaks back into the hull. The return pipe has a rising drainage duct (16) between the lips to lead any oil leaks back into the hull. The return pipe has a syphon head which requires a pressure greater than the oil feed pressure to return the flow. The propeller (1) is sealed against the shaft by sliding ring (4, 5) seals to prevent ingress of seawater. A second drainage duct (15) leads downwards from the space behind the ring seals, with a drainage cock (15') at the bottom to drain out any seawater.

Inventor: JAWOROWSKI ERWIN
IPC: B65D41/38
Filed: 1976-06-11
Abstract: The smooth, unformed mouth edge (2) of the container (1) is fitted with a ring (10) of a hardened moulding material. Said ring can overlap the end face (3) of the mouth edge or extend into the interior of the container aperture. The moulding material of the ring (10) is introduced, e.g. injected, between the mouth edge (2) and the cap edge (7) in the not yet hardened state, as a result of which a clean and particularly tight closure is achieved. It is possible to connect the ring (10) on the one hand firmly to the body and on the other hand releasably to the cap. <IMAGE>

Title: Current to frequency converter - has short circuited photodiode connected to amplifier and driven from light pulses of known width and intensity
Inventor: BUSCH ULRICH DR ING
IPC: G01R19/252
Filed: 1976-10-29
Abstract: A current to frequency converter uses a charge/discharge technique controlled by a photo-diode. A short circuited Si photo-diode (Di), i.e. in the linear part of its characteristic, is connected to the amplifier (A1) and driven from light pulses of known width and intensity. The diode (D1) is unlit in the quiescent state. The output voltage (U1) is constant until the input current changes to (io). Then (Ui) increases until greater than (U2). The comparator (A2) then operates the pulse generator (G). This gives a pulse of width (T) which gives a known charge (TXif) via diode (D1) for current measurement. Voltage (U1) then reduces to below (U2) and the pulse generator is switched off. Pulse frequency (fo) is proportional to current for constant pulse width and intensity.

Title: Vehicle radiator fan pulley drive adjuster - has higher pressure produced from adjusting side spring than from adjusted side
Inventor: KRAG JEP REUTER ING GRAD
IPC: F16H61/662
Filed: 1976-11-08
Abstract: Speed adjusting pulley drive, particularly for radiator fans and other automotive engine accessories, which are commonly driven by a pulley, and whose speed is reduced when the engine speed increases and increases when the engine speed drops, has a pulley (11) in the adjusting system with only two or at most three pulley discs (14). Further units are driven by additional pulley discs (14) fitted on speed governed shafts (15). The speed adjustment is effected either from the driven pulley wheel or from that which is driving; it can also occur between two accessory units driven by the engine. A cone disc-pressure spring (5) installed on the adjusting side of the pulley drive exerts greater pressure than the drive spring (3) on the adjusted side of the pulley drive.
