Title: Domestic telephone communication system - uses microprocessor control which can transfer outside call to another extension
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04Q3/62
Filed: 1979-09-13
Abstract: The telephone system for installation in a home allows one main and four extensions to make internal calls or use the exchange line. When a telephone is engaged on an outside call, it can transfer the call to any other telephone by dialling the extension number. The microprocessor holds the exchange line by connecting a resistor across it and disconnecting it from the exchange busbar. It then switches the second extension to the exchange busbar and rings it. When it answers, both extensions can talk via the exchange busbar. Then the first, replaces the receiver and the second takes the call by dialling the exchange code. If the exchange line is still held after 30 seconds, the microprocessor rings the first extension and switches the exchange line back to it.

Filed: 1979-10-17
Abstract: Me methacrylate, or a mixt. contg. at least 80 wt.% Me methacrylate together with copolymerisable monomers, is bulk polymerised in 2 steps. A syrup is formed in 1st step, by partial polymerisation with an organic peroxide as initiator. Polymerisation is broken off, with a polymerisation inhibitor, after a conversion of at least 20 wt.%. In the 2nd step, the syrup is hardened under radical activity. Novelty consists in using (a) a percarbonate ester (A) as the peroxide in 1st step, and (b) a thioether, organic disulphide or mercaptan as the polymerisation inhibitor (B). Syrup can be hafened in a 2-20 mm layer, to form an acrylic glass, or can be used to impregnate fabrics and webs. (B) dissociates (A) to form a stable syrup between steps. In 2nd step, polymerisation is unhindered, Residual (B) is hardened prod. acts as a heat-stabiliser. E.g. a hardened polymethyl methacrylate plate had vicat softening temp. 112 deg.C falling to 105 deg.C after 30 min. at 160 deg.C as opposed to 100 deg.C in control without thioether.

Title: Ball bearing for wheel carrying brake - has holes in inner race for radial air flow cooling of brake and bearing
Inventor: SCHMID LEOPOLD F
IPC: B60C23/18
Filed: 1980-07-08
Abstract: The ball or roller bearing to support vehicle wheels which are fitted on the inner race of the bearing with a brake drum or brake disc, has holes in an extension of the inner race which act like a radial-flow fan when the wheel revolves. The air flow induced thereby is directed against the wheel bearing and into passages at the back of the brake disc to cool bearing and brake. The inner race (16) of the ball bearing (6) has holes (15) in the flange (4) carrying the brake disc (3) and the wheel (1) which act like a radial fan. The induced air flow (17) partly cools the brake disc through passages (5) and partly the outer race (7). The lubricating oil supply (13) for the homekinetic coupling (11) of drive shaft (14) to inner race communicates through holes (18) with the oil reservoir (8) of the bearing (6). This effects a pressure lubrication at a pressure which rises with the square of the wheel speed.

Title: Sewing machine needle - has displaced channel above the eye to protect the thread
Inventor: ZOCHER JOSEF
IPC: D05B85/00
Filed: 1980-07-21
Abstract: To form the channel (6) in the shaft (2) of the sewing machine needle above the eye (4), a displaced zone is created parallel to the needle axis (7) by two angled sections (9,10), while retaining the cross section dimensions of the needle. The displaced section (8) of the needle shaft (2) is moved from the needle line by an amt. corresp. to 30-60% of the needle thickness, while the angled sections (9,10) defining the displaced zone run at an angle of less than 30 deg. to the needle axis (7). The angled section (9) between the displaced zone (8) and the needle eye (4) starts at the upper end of the eye (4). The needle has a U-shaped cross section along its shaft (2) as far as the eye (4), with approx. parallel side walls at the eye (4) end, or it can have a V-shaped cross section with the side walls lightly angled together at the eye (4). The side walls of the eye (4) are wider than the shaft (2) thickness. The thread groove (5) depth increases before opening into the eye (4). The design gives greater depth where the thread groove enters the eye, giving the thread full protection, with increased free space between the thread and the needle, without loss of needle stability.

Patent DE-3115018-A1 (DE)
Title: Method for producing a hinge part
Inventor: GUIONIE PAUL
IPC: B23K11/14
Filed: 1981-04-14
Abstract: If, in the illustrated contact and clamped-together position of the liner (1) and the plate (7), a resistance welding current is made to flow between the corresponding electrodes, the specific intensity at the contact points between the surface line (2) and the blades (3) reaches a very high value which momentarily causes melting of the contact zones and ionisation of the air. As a result, any contaminants which may be present in the vicinity of the melting zones are flushed away. This results in a kind of arc welding or percussion welding, which ensures that resistance welding is initiated. As the process continues, the contact zones become continuously larger and the specific intensity of the current is reduced in such a way that the final phase can be considered to be spot welding or butt welding. The high degree of reliability and strength of the welding finally produced in this manner makes it possible to use the hinge part produced in this manner for mounting motor vehicle doors. <IMAGE>

Title: Method for the production of the mount of a hairpiece
Inventor: MUELLER KLAUS H
IPC: A41G5/00
Filed: 1981-07-06
Abstract: The invention relates to a method for the production of the mount of a hairpiece with the weldable material of the mount being reinforced in its edge zone. The object of the invention is to design the edge regions of a hairpiece in such a manner that even after relatively long use and the effect of moisture, different temperatures and so forth, the edge region of the hairpiece does not lift away from the head so that a lasting and optimum fit is ensured. The invention is that the weldable material of the mount obtains additional welding points at specified points in the edge zone, and the thus obtained weld seam hardens on a backing corresponding to the shape of the head. The segments in the edge region of the mount can be connected to one another by a reinforcing seam which then likewise hardens on the backing. The reinforcement can also be formed as a film forming the edge zone.
