Patent DE-2926222-A1 (DE)
Title: Elastomer and plastomer processing - after applying ultrahigh frequency waves to preformed strands
Inventor: PAUL TROESTER MASCHINENFABRIK
IPC: B29C48/91
Filed: 1979-06-29
Abstract: Shaped articles are produced from polar rubber /or plastic mixes by extrusion, pressing or injection moulding after the mix has been plastified by first preforming it to a shape which assists the application of ultrahigh frequency (UHF). Subsequent exposure to an UHF field results inchemical and/or temperature rise and the mix is given its ultimate shape immediately afterwards. These microwaves result in a very sbort time in high temperatures which are necessary for the vulcanisation of rubber and crosslinking of plastics. The result is a uniform heating throughout with very exact control and repeatability.

Title: Telephone exchange for preventing spurious drop=out of coupling state - uses added current injection circuit to activate relay until normal conditions prevail
Inventor: SCHOERNER HORST DIPL ING
IPC: H04Q11/04
Filed: 1979-09-27
Abstract: In telephone exchanges the so called 'c' line carries the holding current for at least one holding relay responsible for maintaining the coupling condition between two subscriber lines or one subscriber and an intermediate exchange office. It occurs that spurious, induced voltages reduce the holding current in the 'c' line below 22mA (the allowable minimum) causing the relay and the entire connection to breakdown. To provide a safeguard against such occurrences an electronic current sensor is provided which monitors the holding line current and which, when the current drops below a predetermined value, causes an additional current source, operating from a substantially higher voltage gradient than that which the holding current normally derives from, to be fed into the 'c' line thus very rapidly restoring the current level. As and when thereafter the current level rises above a predetermined current value the current sensor causes the additional current source to be switched off again. This method eliminates spurious breakdowns of telephone connections during the coupling-in or the conversation stages.

Title: Sliced lemon squeezer assembly - has peripheral surround for peel ensuring that pressure is applied to flesh only
Inventor: WAGNER FRIEDRICH
IPC: A47J19/02
Filed: 1979-12-12
Abstract: The press comprises a lower part (1) to take the lemon slice and an upper part (2) for exerting the pressure on the slice. At least one part, pref. the upper part (2), has a pressure face (7) which projects towards the other part thereby reducing the amount of pressure required to squeeze the lemon. Between the semi-cylindrical wall (4) of the lower part (1) which defines the holder for the lemon slice and the pressure face (7) there is a radial spacing A which is sufficiently large to provide a semi-circular annular space (8) which is suitable to take the peel of the lemon slice. The pressure applied acts mainly on the flesh of the fruit whilst the peel is in this annular space (8) so that the optimum amount of juice is always obtained.

Abstract: A thickness shear quartz crystal oscillator has two major surfaces which extend in the direction the of X axis of the crystal and which are 5mm to 10mm long. X-Z plane defined by the X axis and Z axis of the crystal is rotated about the X axis by 35 DEG 08' to 35 DEG 16' so that the major surfaces are parallel to an X-Z' plane defined by the X axis and an imaginary Z' axis inclined to the Z axis at 35 DEG 08' to 35 DEG 16'. One of the major surfaces is displaced in the direction of the Z' axis to thereby cause the side faces of the oscillator to incline at an angle of 4 DEG  to 6 DEG .

Abstract: PCT No. PCT/DE81/00064 Sec. 371 Date Dec. 11, 1981 Sec. 102(e) Date Dec. 11, 1981 PCT Filed Apr. 18, 1981 PCT Pub. No. WO81/03037 PCT Pub. Date Oct. 29, 1981.A method for the pneumatic insertion of the weft thread (24, 24a) into the shuttles (9) of a multi-feed weaving loom. The weft thread (24, 24a), of a respectively predetermined length, is inserted by means of an air flow in an injector (23) into the weft thread magazine (29) of a shuttle (9) traveling in a continuous movement past the injector (23). In order to be able to supply the shuttles (9) rapidly with the particular weft thread required for the fabric panel width in a multi-feed weaving loom, without thereby causing an impermissible strain on the weft thread or being required to extend the length of the weft thread magazine (29) of the shuttles (9), the injector (23) is moved conjointly with the shuttle, e.g. by a gear coupling (34-38) beginning at a start position (I) but, at a slower speed than the shuttle and over shorter distance during the insertion of the thread (24, 24a) into the weft thread magazine (29). At the end of this distance the injector is rapidly returned to the start position by a spring (42).

Title: Optical cable stranding method - splaying fibre=optic conductors with outer fixing spiral of heat-sensitive plastics material
Inventor: SCHOENFELD HANS ING GRAD
IPC: G02B6/44
Filed: 1980-07-17
Abstract: The required number of light wave conductors (1) is fed into a stranding nipple (4) by a guide disc (2) and a perforated disc (3) which is able to rotate in both directions, some eight revolutions, and takes the light conductors with it for stranding. The rotation of the perforated disc (3) changes the conductors in four loops in each direction around a central tube (5)-positioned between the first and second disc when they are then parallel through the stranding nipple (4). After passing through the latter (4), the conductors are combined into a core (7) which is prevented from opening up by a retaining spiral (9) fed from a bobbin (8) in front of the stranding nipple (4). The retaining spiral (9) is made from a plastics material which changesits dimensions when heated, increasing its length and releasing the firm grip it has on the conductors. Increased attenuation due to compressive loads is avoided and the good transmission qualities are retained.
Patent DE-3031033-A1 (DE)
Inventor: GOEBEL PETER
IPC: F24D11/02
Filed: 1980-08-16
Abstract: A method of operating a monovalent alternative absorption heating plant an apparatus operated by this method in which above a predetermined ambient temperature, the system is operated in a heat pump mode and at lower temperatures, in a direct heating mode. The system uses a coolant (refrigerant) circulation path in which the coolant is driven out of a solvent enriched with the coolant, is liquefied, is vaporized by heat exchange with the environment and is absorbed by coolant-poor solvent. The system also has a heat carrier circulation in which the heat carrier is heated by heat exchange with the continuing coolant and thus takes up absorption heat. According to the invention, in the direct heating mode, the heat carrier bypasses the coolant condenser and absorber and is passed through a heat exchanger separate from the coolant condenser and is there heated directly by combustion heat in a heat generator or by heat exchange with the coolant-poor solvent.

Abstract: In the apparatus for monitoring the transport of wire material or band material in non-cutting metalworking, a roller (26) is mounted rotatably on a feed member (10) which is mounted so as to be movable to and fro and is connected to a drive device and which has a clamping device. This roller (26) is in rolling contact with the material strand (12). An electrical or electronic sensor or switch (40) responds to a rotation of the roller (26) only during the material-feed movement of the feed member (10). In this way, the relative movement between the material-feed member (10) and the material (12) is monitored continuously during the feed stroke of the feed member (10), and any relative movement exceeding the value zero in one direction is sensed. An electrical and/or electronic circuit is controlled by means of the sensing pulse. The exact feed of the wire material or band material can be monitored continuously by means of this simple apparatus. <IMAGE>
