Patent DE-3243769-A1 (DE)
Title: Method of traffic sensing on telecommunication lines
Inventor: HERMENTIN HEINZ ING GRAD
IPC: H04M3/36
Filed: 1982-11-26
Abstract: The invention relates to a method of traffic sensing of analog telephone signals with sensors and is characterised in that the signal to be sensed is investigated for amplitude modulation at low frequencies of a few Hz, in that the amplitude of the envelope of this signal is compared with an adjustable threshold value and in that, if the latter is exceeded, the response sensitivity of the sensor is set to a great value and, if it is not exceeded, it is set to a small value. The advantage of this method is that traffic sensing is still possible if the noise signal reaches or exceeds the voice level of someone speaking quietly.
Patent DE-3245338-A1 (DE)
Inventor: BLESING DIETER
IPC: F16J15/3236
Filed: 1982-12-08
Abstract: A U ring in an inwardly radially-open groove in a relatively stationary machine part for sealing a relatively axially-displaceable machine part extending therethrough has a resilient U ring body, a radially-outside statically-acting sealing lip for bearing on the bottom of the groove, and a radially-inside dynamically-acting sealing lip for bearing on the axially-displaceable machine part. The axial spacing of the statically-acting sealing lip from the adjacent end face of the groove is greater than that of the dynamically-acting sealing lip, whereby the dynamically-acting sealing lip tilts away from the axially-movable machine part when the latter forces the end of the U ring against the end face of the groove to relieve pressure along the axially-moving machine part.

Title: Axially deformable collar thrust cage for ball bearings
Inventor: HOFMANN HEINRICH
IPC: F16C33/41
Filed: 1983-01-11
Abstract: The axially deformable collar thrust cage for one- or two-row ball bearings made of material of low deformability, in particular plastic, has an axially directed recess in each of the webs and at least one retaining projection for the balls at the open ends of the pockets. The intention is to achieve reliable axial guidance of such a cage by simple means under all operating conditions and it should be possible to snap the cage in over the balls without problems despite the robust design and the use of material of low deformability. This is achieved by virtue of the fact that the axial recesses (9) extend to a point just behind that section of the web parts (6', 6'') at which the retaining projections (8) face the balls (3) and that the web parts (6', 6'') adjacent to the retaining projections (8) are connected to one another by preferably rounded sections (10). <IMAGE>

Title: Process for the production of foundry cores from greensand
Inventor: PISTOL GUENTER DR ING
IPC: B22C9/10
Filed: 1983-04-05
Abstract: The invention relates to a process for the production of foundry cores from bentonite-bound moulding sand. The aim of the invention is to transfer to the production of foundry cores the advantages connected with the production of moulds from bentonite-bound moulding sand, such as low moulding-material costs, rapid production and immediate readiness for use, with the condition that the cores be produced with sufficient strength for handling and at a production rate corresponding to the modern moulding plant. This is achieved according to the invention in that the bentonite-bound moulding sand is compressed to the required strength by pressing in a mould to form core halves, with the simultaneous formation of a lost press ball and a slight excess volume formed between this and the core halves, in that subsequently the press ball is broken off, the associated core halves are brought together and are united to form a core by pressing in the excess volume formed on at least one core-dividing surface.

Title: Roundabout
Inventor: VOGEL WOLFGANG DIPL ING
IPC: A63G1/40
Filed: 1983-05-30
Abstract: In the previously known roundabouts, a rotary movement of a rotary structure, provided on its periphery with passenger cabins, was only possible about an axis of rotation which is constantly perpendicular to the lifting axis of the lifting arm. The consequence was only moderate excitement of the passengers whilst simultaneously lowering the feeling of safety of the passengers in the case of malfunctions when the arm is returned to its starting position. In order to overcome such disadvantages, the arm (2) for lifting and returning the rotary structure (3) is formed by at least two levers (4, 5) which are arranged in parallel and offset relative to each other in the swivel plane and with which the rotary structure (3) can be adjusted during the lifting or returning operation in a plane of rotation which is independent of the swivel angle (6) of the arm (2).   <IMAGE>

Title: Chain brake device
Inventor: SCHLIEMANN HARALD DIPL ING
IPC: B27G19/06
Filed: 1983-07-08
Abstract: A spring-loaded brake for motor-driven appliances is operated by means of such a brake device. The device has a trigger, which is connected to a tensioning element and a brake element. A brake strap applied around a brake drum is fixed to the brake element, which brake strap is held at the other end on an appliance housing. In a release position, in which the brake strap is lifted off from the brake drum, the brake element is held by means of a retaining device against the force of the brake spring acting on it. The brake element can be easily and rapidly moved from the brake position into the release position in that the tensioning element jumps around the cam path of a cam arranged on the crankshaft of the chain brake device. The tensioning element is thereby swivelled under the force of the cam so that it is snap-connected to the brake element as part of the retaining device, as a result of which the brake element is swung against the force of the spring and the brake strap is lifted off from the brake drum.

Title: Process and apparatus for combining two yarns running parallel to form one yarn
Inventor: BROCKMANNS KARL-JOSEF DIPL ING
IPC: D01H4/16
Filed: 1983-08-23
Abstract: In the two gussets which are limited by two rotationally symmetrical friction elements (7, 8) of a friction spinning unit (2), two yarns (34, 35) are produced and are drawn off continuously in the direction of the arrow (36). The front yarn (34) runs successively through the two front gussets of a first (3, 4) and, if appropriate, of a second (5, 6) pair of friction elements. The rear yarn (35) thereafter runs through a deflecting device (54) and then meets the front yarn (34) at the combination point (53), whereupon the two yarns are combined to form a single yarn. Both the radially adjacent (3, 4; 5, 6) and the axially adjacent (3, 5; 4, 6) friction elements are driven in opposite directions of rotation. The casings (37 to 40) of the friction elements (3 to 6) are subdivided alternately into portions (49) of high yarn attractive power and portions (50) without any yarn attractive power. Both the radially adjacent (3, 4; 5, 6) and the axially adjacent (3, 5; 4, 6) friction elements have mutually opposite portions of unequal yarn attractive power. All the friction elements (3 to 6) are driven at the same circumferential speed. The yarns produced in the friction spinning unit (2) are equipped, when they run through the pairs of friction elements (3, 4; 5, 6), with an alternating twist which leads to a good combination of the two yarns to form a single yarn, as soon as the yarns ...

Title: Heat exchanger
Inventor: KAEHMANN PETER
IPC: F23G5/46
Filed: 1983-10-08
Abstract: The invention relates to a heat exchanger for recovering heat from combustion gases which contain gaseous substances which when a specific temperature is exceeded are deposited by sublimation, having at least one housing (1), through which the medium to be heated flows and which is penetrated transverse to the direction of flow of the medium to be heated by tubes (6) through which the combustion gas flows and which are mounted in tube sheets (2, 3) assigned to the inflow side and to the outflow side of the medium to be heated. In order to exclude the deposition of sublimation products in the tubes (6) in such a heat exchanger, the invention proposes that the length of the tubes (6), which come into contact with the medium to be heated, increases over the flow path of the medium to be heated in such a way that the temperature of the combustion gas remains above the sublimation temperature in all the tubes (6). <IMAGE>

Title: Dental instrument for pulling off firmly seated dental prostheses
Inventor: HUEBNER HANS LUDWIG
IPC: A61C3/16
Filed: 1984-02-23
Abstract: A so-called shepherd's crook which contains an angularly projecting arm or hook to be pushed under the dental replacement piece instead of an eye 1 or a round hook 7 was conventionally used for pulling off artificial dental replacement pieces, such as crowns, crown attachments and bridges. By tapping the weight 3 movable along the shaft 2 several times against the knob 4 the dental replacement piece is knocked off the dental stump. A great disadvantage of this is that the dental replacement piece may be notched or, in the case of porcelain pieces, may crack; furthermore, it spins away in an uncontrolled manner. According to the invention, the dental replacement piece is tied up with a wire and pulled off by pulling abruptly on the wire used for tying up without the possibility of the piece being damaged or spinning away. For this purpose, a new shepherd's staff is used which has an eye 1 or a round hook 7 for accommodation of the free end of the wire used for tying up. <IMAGE>
