Patent DE-2506945-A1 (DE)
Title: Bottle top profile involving security foil - with a peripheral recess to facilitate gripping the foil
Inventor: CROS MODESTO
IPC: B65D39/02
Filed: 1975-02-19
Abstract: Bottle tops has a cap secured by an annular recess close to the top of the bottle and with a flat lip for supporting a welded foil as a secondary tamper-proof cover, where a segment of the lip is recesses sufficiently to facilitate getting a grip on the tear-off foil. Used esp. for the tops of PVC or analogous bottles. Foils which can be gripped and peeled from one edge reduce the probability of manual contact with and consequent contamination of the inside walls of the bottle or container, of fully supported foils which are often punctured inwards.

Title: Repairing enamelled appliances, esp. ovens - coated with self cleaning enamel, using aluminium repair enamel baked by using the oven
Inventor: LEINEWEBER KARL
IPC: C23D13/02
Filed: 1975-06-11
Abstract: Process for the repair of electrically heated, enamelled metal appliance parts with damaged zones in the layer of enamel, esp. for pyrolytically self-cleaning baking and roasting ovens made of enamelled steel sheet. The novelty is that the damaged zones are coated with a layer of aluminium enamel possessing a m.pt. near the operating temp. of the appliance, so that the Al-enamel is baked in during operation of the appliance. The Al-enamel pref. has a m.pt. just below the max. operating temp. of the appliance, esp. a m.pt. of 424 degrees C, and is baked in while the baking or roasting oven is held at the self-cleaning temp. of 500 degrees C for 90 minutes. Damaged parts of the enamel layer inside an oven can be repaired in situ, without dismantling the oven so that only low repair costs are involved. The process can also be used for other parts such as baking trays or cooking utensils.

Title: Directional microphone with light passing through aperture - to give light cone coincident with best reception lobe of microphone
Inventor: MANGOLD HELMUT DIPL ING
IPC: H04R1/08
Filed: 1975-12-03
Abstract: The directional microphone has a light source to indicate to the speaker when he is within the optimum area of reception. The light source is located inside a cap, or similar, which fits onto the microphone housing. The cap has an aperture to allow light from the source to subtend an angle equal to the angle of the directional lobe. When the speaker moves outside the area defined by this angle he can no longer see the light and therefore knows he is outside the optimum region of reception of the microphone.

Title: Subscriber electronic supply circuit - is for telephone PBX with loop current monitoring and ringing signal connection
Inventor: REUSCH HARTMUT
IPC: H04M19/00
Filed: 1975-12-11
Abstract: An electronic supply circuit for subscribers for a telephone PBX has also a hybrid set for change from two to four-wire operation. Two current generators hold constant loop current. A Zener diode at the junction point of two balancing resistors stabilises current during signalling by application of earth potential to one of speech wires. Current from current generators is used for l.f. signal modulation. A circuit connected to two base resistors serves as modulator. Loop current is monitored and evaluated by interrogation of each wire by a transistor. Their signals are applied through logic circuits to a central control unit. Half-wave ringing voltage is applied through a thyristor optical coupling to one of the wires.

Title: Metal recovery from sulphide ores - by nitric acid leaching and heating to remove crystalline sulphur
Inventor: POSEL JOHN G
IPC: C22B15/00
Filed: 1976-04-15
Abstract: Cu, Ag, Ni, Co and/or Zn are recovered from their sulphide ores by leaching with a 30-50 vol.% HNO3 soln., heating the soln. to a temp. at or above the m.pt. of sulphur while the soln. is held under pressure in a relatively inert atmos., controlling the temp. of the soln. to ppte. sulphur, separating the sulphur and recovering metal values from the acid soln. Using a leaching time of as little as half an hour, 99+% metal recoveries are obtd.; the leaching operation selectively insolubilities iron or sulphur in the ore so that these can be readily separated as a commercially valuable by-product; the leach soln. lends itself to known preferential pptn. metal recovery techniques; the metal values can be solvent extracted without the problems of lasting pptes. forming in the leach soln. and fouling the extn. process; iron can be economically removed from the leach soln. without addn. of large amts. of acid neutraliser.

Title: Inflatable column for lifting small loads - has cylindrical sections with flexible skirts to give telescopic extension when being erected
Inventor: PIETZSCH LUDWIG DR ING
IPC: B66C23/687
Filed: 1976-06-23
Abstract: The inflatable vertical column is used to lift and to hold small loads. The column is made from a number of cylindrical sections which are of light weight but of rigid construction. The stations fit coaxially into one another so that before the column is inflated, it forms a compact package. When air or a gas is pumped through the valve, the rigid cylindrical sections start to rise until the column is extended to its full length. Flexible skirts which link the cylindrical sections prevent the air from escaping. The column is stabilized by a number of external stay wires and an internal cable which is attached to a reel.

Title: Derricking jib crane with tailweight - has one tailweight rope tie member anchored near jib foot and other one flexible
Inventor: TAX HANS
IPC: B66C23/76
Filed: 1976-08-06
Abstract: The crane has a jib derricking on a frame on a horizontal axis under the action of a rope reeved from a point on the rear of the frame round one above the jib derricking axis and to one near the jib head. A tailweight is attached to one end of a rope reeved over a pulley on a fixed mounting to the junction point of two tie members above teh bottom portion of the jib, one of these members being closer to the frame than the other. When the jib is drricked nearly to the vertical position the effect of the tailweight is almost completely cancelled out. The nearest of the two the members to the frame is anchored either to the frame itself or to a point on the jib near its derricking axis. The other tie member at least is flexible.
