Patent DE-3103780-A1 (DE)
Title: Feed device for tin solder in soldering
Inventor: PAUNOVIC MLADEN
IPC: B23K3/06
Filed: 1981-02-04
Abstract: The device is an attachment on the soldering bit which is used for soldering in electronics. Its task is to feed the tin-solder wire to the tip of the soldering bit. Thus one hand is freed for holding the object to be soldered. The device is adapted to the handle of the soldering bit and thus holding of the soldering bit is not made more difficult and the tin-solder feed is operated by the free index finger. The components of the tin-solder feed device are: the housing, the guide tube, the serrated wheel and the flat spring. The passage for the tin-solder wire runs along the housing. Mounted in the centre of the housing is the serrated wheel, which partly projects from the housing so that it can be operated by the index finger. The wheel projects into the tin-solder passage. Below the wheel is the flat spring, which presses the tin-solder wire onto the wheel and only permits the wire to travel forward. Fastened to the front end of the tin-solder passage is the tube which directs the tin-solder wire to the tip of the soldering bit.

Title: Tree-cutting implement
Inventor: SCHMIERER HEINZ DIPL ING
IPC: B23D51/02
Filed: 1981-02-13
Abstract: A description is given of a tree-cutting implement, in which, via a motor, a saw blade held in a blade head housing is moved backwards and forwards via a drive connection running in a carrying tube. The saw blade is connected to a crank mechanism via a connecting rod, connecting rod and crank mechanism being covered over by a covering hood which is held on the blade head housing via a plug-in and/or locking connection and is used at the same time as support means for a spring element which acts on the connecting rod. The advantage of this design lies in the possibility of simple cleaning, this being made possible by the rapid and simple capacity for removing the covering hood.

Title: Single-phase miniature stepping motor
Inventor: MALKIN DANIEL DAVIDOVIC
IPC: G04C13/11
Filed: 1981-02-26
Abstract: A single-phase miniature stepping motor is proposed which contains a stator having two pole shoes (1 and 2) whose cylindrical surfaces (3 and 4) face one another. A two-pole rotor is arranged between the pole shoes (1 and 2), and a means for fixing the rotor is arranged between the stator and the rotor. According to the invention, the means for fixing the rotor is constructed as a ring (8) whose thickness is less than the thickness of the pole shoes (1 and 2) of the stator and whose width is variable depending on the angular coordinate of the stator. The present invention can be used most effectively in the clock industry, in the manufacture of electronic/mechanical wrist watches having hands. <IMAGE>

Title: Denture model
Inventor: ZEISER MANFRED P DR
IPC: A61C9/00
Filed: 1981-03-07
Abstract: In a denture model for the fabrication of dental replacement parts in which dental stumps are releasably fixed via pins to a dimensionally stable baseplate, the reception bores for the pins in the baseplate are to be adapted to the pin shape in sections only, whereas in other sections between the wall of the bore and the outer surface of the pin there is no contact. By the reduction of the bearing surface of the pin in the bore of the baseplate, removal of the pins from the baseplate is facilitated.

Title: Multi-roll universal stand
Inventor: KOSTOGRYSOW IGOR D
IPC: B21B13/10

For this purpose, a number of rods (10) corresponding to the number of axles (4) is provided and each of these rods lies parallel to the corresponding axle (4) and is connected to two mounts (7), one of which is connected fixedly to one end of the rod (10) and the other is coupled to the other end of the rod (10) in such a way that the possibility of adjustment along the rod (10) and of fixing in the chosen position is ensured. <IMAGE>
Patent DE-3124104-A1 (DE)
Title: Drill and milling cutter preferably for machining printed circuits as well as other materials
IPC: B23B51/00
Filed: 1981-06-19
Abstract: The invention relates to wear protection for drilling and milling tools which are subjected to high rubbing and abrasive wear in combination with considerable alternating bending stresses, in particular at high speeds. Conventional highly wear resistant coatings certainly increase the wear resistance of the tools, but at the same time they reduce their bending and fatigue strength under reversed stresses and the impact resistance. The coating proposed according to the invention, with a carbon layer of certain thickness and diamond-like hardness, produces a substantial increase in the wear resistance while at the same time maintaining the bending and fatigue strength under reversed stresses of the parent material.

Inventor: BECKER REINHOLD DR ING
IPC: A22C11/02
Filed: 1981-07-01
Abstract: A device for deshirring, smoothing and braking a shirred tubular casing during stuffing of the casing with a fluid mass flowing under pressure from the stuffing horn of a stuffing machine into the tubular casing. The device comprises an annular body having a central opening releasably securable to the stuffing horn, said annular body having recesses on its outer surface extending parallel to its longitudinal axis. The recesses have a substantially U-shaped, V-shaped or rectangular cross-sectional configuration or end view configuration. The configuration of the braking and smoothing elements corresponds to that of the recesses in the surface of the annular body. The braking elements and/or the annular body are displaceable relative to each other either parallel to the longitudinal axis of the stuffing horn or the elements are displaceable perpendicular to the longitudinal axis of the stuffing horn so that the braking elements can be extended into the recesses or spaced away from the recesses. An apparatus comprising a device of the aforementioned type is also disclosed.

Title: Relief valve for the start-up operation of reciprocating or rotary-piston compressors
Inventor: JAHNS GERD
IPC: F04B49/24
Filed: 1981-08-25
Abstract: A relief valve for blowing off the delivery stream of reciprocating or rotary-piston compressors, which are driven by electric motors under star-delta control, during the start-up operation comprises a blow-off port (5) which is open to the atmosphere and connected to the discharge line of the blower, and can be closed, via a valve element (9, 10) spring-loaded in the direction of opening, by means of bearing on a valve seat (20). So that a relief valve of this type, while being of technically simple and robust construction, operates reliably, while minimising mechanical and control complexity, it is provided that the electromagnet (19), which is excited in the star phase of the electric motor and is de-energised in the delta phase, in the star phase holds the valve element (9, 10) in its open position and in the delta phase releases it, and that the valve element (9, 10) is arranged upstream of the valve seat (20), seen in the blow-off direction of the delivery stream, and can be forced thereby, when in the released state, against the valve seat. <IMAGE>
