Title: Enlarger lens with illuminated aperture setting - has three mode aperture setting ring for click stop, continuous or non-illuminated settings
Inventor: CREMA ROLF
IPC: G02B13/24
Filed: 1977-06-04
Abstract: A projecting lens for process, reprographic and enlarging equipment has an aperture setting ring and illumination to show the selected aperture. The selection ring is click stopped in one mode, continuously adjustable in a second and without the illuminated stop setting in the third mode. These three operating modes are vertically displaced for selection around the lens barrel. The aperture setting ring (10) is equipped with aperture scales (29, 30) illuminated by reflected light through chambers which are open to light from the enlarger light source - chambers (25, 26, 28) with reflecting surfaces (27).

Title: Mixing gas into liquid in covered vessel - using agitator nozzle mounted on floats with hole in cover through which stem can project
Inventor: HORB JOHANN
IPC: B01F13/00
Filed: 1977-06-25
Abstract: Aqueous liquids have gas dispersed in them by a gas distributor which is mounted on a float and of which the position varies with the level in a covered vessel. Gas is conveyed to teh distributor via a line. The liquid is held in an covered vessel. The device is held in a mounting on a float and it is centred on an opening in the proof of the vessel. The distributor consists of >=1 rotating nozzle. To drie the distributor a motor is provided outside the liquid, mounted on th float with shaft down to the nozzles. Liquids e.g. contain bi-valent and liquid manures. Generally the latter is treated in covered vessels and known distributors do not adequately allow for changing levesl in covered vessels. The invention avoids that problem.

Title: Roofing panel - made in mould from plastic foam, esp. polyurethane, with waterproof foil covering
Inventor: GEESSINK BERNARD THEODOOR
IPC: E04D3/35
Filed: 1977-11-05
Abstract: A prefabricated roofing panel is made of plastic foam material, pref. flat on one side and with corrugations on the other. A waterproof covering foil is attached directly to the corrugated surface. This saves the manual waterproofing of the plastic foam on site which consumes much labour. It eliminates fixing problems. Typically, a flat plate, e.g., made of fibreboard, is filled with plastic foam and covered by a waterproof foil.

Title: Two-line transmission circuit for digital signal - has disturbance-free characteristics with one signal line and one reference line
Inventor: MAIER KLAUS ING GRAD
IPC: H04L25/00
Filed: 1978-02-10
Abstract: A circuit is used to transmit non-symmetrical digital signals along long lines. It is free from the effects of disturbances. The circuit has at least two lines. One line is used by the signal to be transmitted and the other line is used by a voltage reference. The signal transmitter has a constant current circuit for the signal. The receiver has a terminal resistance which produces a voltage drop between the signal line and the voltage reference line. The voltage reference is chosen above a threshold and has a value which does not affect the signal transmitted. The receiver is actuated by the voltage drop produced by the signal.

Title: Vehicle alternator bearing lubrication unit - has wear part under spring tension for contacting revolving shaft
Inventor: HAGENLOCHER WALTER
IPC: F16C33/66
Filed: 1979-05-15
Abstract: Refilling of lubricant for bearings of vehicle alternators is made after a given number of rotor turnings, and thus extends the service life of bearing and improves the reliability of the unit. This is achieved with a wear part (18) sliding in recess (16) of the bearing boss (11) in the alternator. The wearing part is loaded by spring (19) to ensure its rubbing contact with the shaft (15). After a certain number of shaft revolutions the wearing part simply frees the grease in a recess (16) to flow into the space between the outer and inner races (13, 14) of the bearing. Instead of the sliding wearing part, there are other designs for implementing the same principle for extending lubricant supply to the bearing.
Patent DE-2926918-A1 (DE)
Title: Strain relief for cable in moulded-on plug connector - incorporating attachments for locally increasing insulated conductor dia. inside plug body
Inventor: GAENSLEIN HANS-GUENTER
IPC: H01R13/504
Filed: 1979-06-29
Abstract: Individual cable cores (11) are secured against movement inside the moulded on plug body (16) when a tensile load is applied to the cable. To give the necessary location, the diameter of the insulated conductor is locally increased (12). The required enlargement can be produced by attaching a disc with some means for arresting it on the core. Alternatively, a ring of adhesive material can be formed on locally. As a further safety measure, the surface of the insulated conductors, and also that of the cable sheath (10), can be coated with a heat activated adhesive (13,14). This adheres to the plastic material used for the plug body during moulding.

Title: Relief patterning of fabric surface - by heat-embossing followed by monomer surface-grafting by high-energy beta-radiation
Inventor: DULLING ACHIM DIPL ING DR
IPC: D06C23/04
Filed: 1979-07-24
Abstract: Single-step process for producing a relief pattern on a fabric surface uses a differential heat-treatment to vary the absorption characteristics of the fabric, which is then treated with a liquid monomer and subjected to high-energy radiation to polymerise the monomer and graft it onto the fabric surface. Differential shrinkage produces a three-dimensional surface texture. Process produces novel effects by a single operation, which simultaneously improves dyeability, moisture absorption, and anti-static behaviour.
