Patent DE-3205017-A1 (DE)
Title: Power take-off
Inventor: UTSCH BERTHOLD DR
IPC: F02B67/06
Filed: 1982-02-12
Abstract: On an internal combustion engine (10), preferably in motor vehicles, a power take-off is arranged for driving units (18) such as generators, fans or the like. Between internal combustion engine (10) and unit (18) there is at the same time a transmission (15) which can be set by way of a speed governor (19) to constant output speed for the unit (18), preferably a stepless belt transmission. In this way it is possible to drive the units at constant speed with varying engine speeds. <IMAGE>

Title: Method for traffic recording of analog telephony signals and circuit arrangement to carry out this method
Inventor: KORN JOEL DR ING
IPC: H04M3/36
Filed: 1982-02-18
Abstract: Method for traffic recording of analog telephony signals through signal level evaluation using AC current sensors on telecommunications paths which form an AC loop during occupancy with or without DC flow, characterised in that, in addition to the AC current sensors, a DC current sensor is provided in each case by which the DC loop current is evaluated and in that, depending on the loop type, the AC current sensor and/or the DC current sensor are used for traffic display. In an optimum embodiment, an additional DC voltage sensor (GSPS) and a DC current sensor (GSTS) act via a logic circuit (S) on the AC current sensor (WSTS). The present loop type is automatically identifiable with such an arrangement and traffic charging based on both occupancy time and utilisation time is possible. <IMAGE>

Title: Process and apparatus for expanding shrink-fit tubes
Inventor: LOCZENSKI MARTIN ING GRAD
IPC: B29C35/04
Filed: 1982-04-07
Abstract: The novel process and the corresponding apparatus for expanding shrink-fit tubes consists in that an unexpanded shrink-fit tube (8) under gas pressure is passed through a liquid temperature-controlled zone (10) as heating zone, in which the pressure of the heat-transferring liquid (12) is made to match the gas pressure in the interior of the tube. Floating of the tube due to its buoyancy is avoided by a hold-down device (15), which is designed as a cross-sectionally approximately bell-shaped limiting channel (16, 17). <IMAGE>

Patent DE-3229366-A1 (DE)
Title: Device for feeding experimental animals
Inventor: KIEPER JOACHIM
IPC: A01K1/035
Filed: 1982-08-06
Abstract: Such devices are used for studies on experimental animals. These devices are suitable for re-equipping existing standard animal cages, especially on the wire lids of these cages. The feeding devices by means of which the time, duration and frequency of feeding of the experimental animals can be preselected and determined are designed in three possible versions. In one model (Figure 1) the food basket is adjusted to suit the contours of the cage lid and can be raised and lowered and thus regulates access to the food. In the design with a flexible wire mesh closure (Figure 2) the food rack is opened or closed. From the rack (Figure 3) closed in the manner of a container the animals are allowed to or prevented from reaching the mealy food depending on the position of the movable food trough. The automatic feeding possible with the equipment described controls the start and end of the meals. Hitherto, feeding in experiments on rodents was ad libitum: i.e., the amount and frequency of withdrawal and consumption of permanently available food are up to the discretion of the animal. The feeding devices now make possible restricted food consumption which takes account of aspects of diurnal rhythm. <IMAGE>

Patent DE-3248373-A1 (DE)
Title: Method of manufacturing connecting rods, in particular for internal combustion engines
Inventor: BAN KEISUKE
IPC: F16C7/00
Filed: 1982-12-28
Abstract: Method of manufacturing connecting rods for internal combustion engines, which includes stages for forming a fibre bundle of unidirectional inorganic fibres, for arranging the fibre bundle in a shaping container and for heating the fibre bundle for the purpose of the partial interwelding of the fibres. The partially welded fibre bundle obtained in this manner is positioned in a mould in such a manner that an additional spacing arises for achieving a predetermined additional finishing thickness between the fibre bundle and the cavity wall. A melted light-metal alloy is filled into the mould under high pressure, namely 500-2000 kg/cm<3>, an annular matrix layer being formed around the fibre bundle. A rod-shaped section of the connecting rod thus obtained is finished in order to eliminate defects which can arise as a result of the casting process, namely for example the possibility of a fatigue crack, a bubble or mixed-in oxidised substances. The finished connecting rod has a circular or an elliptical cross-section.

Patent DE-3328791-A1 (DE)
Title: Glass-block wall
Inventor: ALBERS AUGUST DR ING
IPC: E04B2/16
Filed: 1983-08-10
Abstract: A glass-block wall comprising glass blocks, the horizontal joints of which consist of horizontal double T-section strips running from wall to wall, and the vertical joints of which are formed from short portions of the same section, is clamped in a fixed frame. The double T-section is inserted into the groove, which runs all the way round the interior of this glass block, as a spring. It bridges the individual joints and forms the statically bearing framework of the glass-block wall, the loads of which are transmitted, on the inside of the groove in the glass block, from block to block via the horizontal webs. After erection of the carcase, a permanently elastic putty is introduced from outside into all the joints in order to seal the inner framework against the passage of water and air and to compensate for the manufacturing tolerances between glass blocks and strips. Protective and decorative strips, which are completely separated from the inner framework and have no static function, are then pushed with their retaining webs into the putty and elastically anchored there.

Title: Chopping-type hammer mill for crushing material
Inventor: STEFFENS BERT
IPC: B02C13/282
Filed: 1984-04-17
Abstract: With the invention, a chopping-type hammer mill for crushing material is provided. This chopping-type hammer mill has a rotor around whose axis of rotation radial beaters are arranged, which, by means of rotation, form a, preferably elongate, rotation body about the axis of rotation. The rotor rotates in a housing with an inlet opening and an outlet opening. Between the rotor and the outlet opening, tearing and/or chopping elements are arranged at a distance from the rotor over an angular region which extends from the, in the direction of rotation of the rotor, downward-movement end of the inlet opening in the direction of rotation of the rotor as far as the region of the outlet opening. In addition, a material flow blocking element is arranged between the, in the direction of rotation, downward-movement end of the outlet opening and the, in the direction of rotation of the rotor, upward-movement end of the inlet opening. The material to be crushed is fed to the rotor via the inlet opening, crushed by the beaters, further crushed by the tearing and/or chopping elements and discharged outwards through the through-openings between the tearing and/or chopping elements and the housing and the tearing and/or chopping elements via the outlet opening.
Patent DE-3416637-A1 (DE)
Title: Swash plate compressor
Inventor: SWAIN JAMES C DIPL ING
IPC: F04B27/18
Filed: 1984-05-05
Abstract: A swash plate compressor is designed in such a way that the tilt angle of the swash plate (20, 20a) is changed as a function of the difference between the resulting reaction force, which is exerted by the pistons (26) during each of their compression strokes, and the pressure in the interior, i.e. around the swash plate (20). The compressor comprises spring means (31), which continuously act on the swash plate (20) in a direction reducing the tilt angle, and further comprises a regulating valve arrangement (38) which, as a function of a signal (A-K) which is characteristic for at least one given parameter, selectively connects the interior (42) with a suction chamber (33) and/or a discharge chamber (34), in order to achieve a rapid pressure change in the interior (42) and thus a rapid-response regulation of the tilt angle of the swash plate (20, 20a). <IMAGE>
