Title: Device for grading fruit or vegetables
IPC: B07B1/15
Filed: 1981-04-28
Abstract: The invention relates to a device for grading fruit or vegetables having a plurality of rollers (5) which rotate about their longitudinal axes and form grading gaps (21) between them through which the graded articles fall onto rotating chutes (22) which carry them onwards. Groups of rollers (2, 3, 4) with different grading gaps (21) are respectively arranged at a plurality of different levels and convey the material (22) to be graded towards the longitudinal axes of the rollers (5) from a feeding end (11) to a delivery end (12). On the conveying path, articles, which are smaller than the grading gap (21) set in each case fall through the grading gap onto a chute (22) which takes the said articles to the delivery end (11) of the next lowest group of rollers (3 and 4 respectively). Articles which do not fit through the set grading gap (21) of a group of rollers (2 and 3 and 4 respectively) are carried by the rollers (5) up to the delivery end (12) of the group of rollers and there fall onto a chute (23) via which they reach a conveyor (24 and 25 and 26 respectively) which is arranged downstream. <IMAGE>

Title: Switch
Inventor: KAKUTA TOSHIO
IPC: H01H1/24
Filed: 1981-05-22
Abstract: A segment holder (35) is arranged in a housing (11) such that it can pivot, and a multiplicity of contact wires (53) extend essentially at right angles to the axis of the pivoting movement of the segment holder (35). The contact wires (53) are spaced apart from one another along the axis of the pivoting movement of the segment switch (35). The segment holder (35) is prestressed in one direction by the elasticity of the contact wires (53). If a driver (61), which is connected to the segment holder (35), is operated from the outside of the housing (11), the segment holder (35) is pivoted against the prestressing force applied to it in order to make or break an electrical contact between the contact wires (53) via a segment or segments which is or are fitted on the segment holder (35). <IMAGE>
Patent DE-3125351-A1 (DE)
Title: Fastening element for line connections
Inventor: HETTICH GERHARD
IPC: F16L33/20
Filed: 1981-06-27
Abstract: The invention proposes a fastening element by means of which line ends, hoses (10), pipes and the like are fastened on attachments such as connection spigots (11), coupling pieces and hose nipples. The fastening element comprises a metal ring (13) which is pushed over the line end and is reduced in internal diameter by a permanent wave-shaped deformation in the axial direction. Owing to the reduced internal diameter of the metal ring (13), the line end is reliably clamped, over the entire circumference, in a uniform manner on the attachment (11) which has been pushed into it. <IMAGE>
Patent DE-3125810-A1 (DE)
Title: Hydraulically actuated punching machine
Inventor: ISHIHARA MASAMITSU
IPC: B21D28/00
Filed: 1981-06-30
Abstract: In a hydraulically actuated punching machine (10), a cylinder (18) is divided into a first and second chamber (22, 23) by a head (20) of a piston (19), so that pressure oil can be conveyed into the first chamber (22). The second chamber (23) is able to communicate permanently with an oil reservoir (16) via a passage (32) which acts as a regulating valve, so that the second chamber can be filled with normal pressure oil. Pretensioning means (33) for returning the piston are arranged in the second chamber (23). In this design, the oil at normal pressure flows out of the oil reservoir (16) through the passage (32) into the second chamber (23) when the capacity of the second chamber (23) is increased by the piston (19) returning. As the rate of flow into the second chamber (23) through the passage (32) is limited, the oil at normal pressure generates resistance in the second chamber (23), which resistance limits the return speed of the piston (19). This ensures that the return speed of the piston (19) will never change abruptly even when a gudgeon (26) leaves the punched hole and reduces the load on the piston (19). The pretensioning means (33) for returning the piston are therefore not suddenly deformed, but are only subject to a continuous deformation, which means that they do not generate a large breaking load. <IMAGE>

Patent DE-3132244-A1 (DE)
Inventor: KIMPEL ROLF-DIETER DIPL PHYS
IPC: H01H51/22
Filed: 1981-08-14
Abstract: An electromagnetic relay has a hallow coil body and coil having a longitudinal axis with a bar-shaped armature pivotably mounted for movement in and extending through the coil body, a permanent magnet arrangement having polarization directions perpendicular to the coil axis, two yokes disposed in a single plain parallel to the permanent magnet arrangement, two pole plates connected to the yokes and also extending perpendicular to the coil axis, and a flux plate overlapping and spaced from the yokes and having a flat segment with the magnet arrangement being disposed in the volume defined between the overlapping area of the flux plate and the yokes, the magnet arrangement extending substantially longitudinally parallel to the coil axis. The structural arrangement of the flux plate and yokes so as to define a volume which can accommodate the magnet system permits the magnet system to be encompassed within the relay without adding to the overall length thereof, thereby adapting the relay to miniaturization. Additionally, the surfaces of the yokes and permanent magnet can exhibit a relatively large area, again without causing any increase in the length of the relay.
Patent DE-3133518-A1 (DE)
Title: Electronic switch
Inventor: RALL BERNHARD DIPL ING
IPC: H04M1/74
Filed: 1981-08-25
Abstract: As a protection against polarity reversal with little voltage drop, the protection against polarity reversal also being switchable, particularly for terminals in telecommunications systems, a bridge circuit of at least four VMOS transistors with gate protection is proposed in which the VMOS transistors are operated inversely in the turned-on state. A modification of this principle allows a bidirectional electronic switch, which has a low forward voltage (0.1-0.2 V) with a high reverse voltage (300 to 400 V), to be implemented as replacement for relays by means of two VMOS transistors connected in series with opposite polarity.
Patent DE-3136738-A1 (DE)
Title: Device, in particular for guiding and storing optical fibres inserted into or led out from the device in the bundle, and a comb element, in particular for use with such a device
IPC: G02B6/44
Filed: 1981-09-16
Abstract: In a device (1), in particular for guiding and storing optical fibres (3) inserted into or led out from the device in the bundle, the optical fibres being fed individually or in pairs separated in the inlet of the device to a joining point (14) via a supply winding (12) and being led out again from the device (1) via a supply winding (12) and by being brought together to form a bundle, the aim is to provide a solution by means of which each optical fibre (3) can be guided separately and stored individually in a detachable way just like the joining point (14), which is also to be easily accessible, and in the process it is to be possible at the same time to achieve an ordering system which is visible at a glance. This is achieved by providing for the purpose of separating and bringing together the individual optical fibres (3) at the device input and device output, respectively, a comb element (4) in which the conductors (3) are guided individually or in pairs between the comb teeth (16) and are prevented by means of a device (19, 20) from escaping from the comb teeth interspaces (17) in the assembled position. <IMAGE>

Title: Device for making through-contact holes in an electrical printed circuit panel, in particular one based on ceramic substrate.
Inventor: KRIEGER FRIEDRICH DIPL ING
IPC: H05K1/03
Filed: 1981-12-30
Abstract: To make through-contacts between conductor tracks on either side of a substrate (2) made, for example, of ceramic, a plunger (6) whose diameter is slightly less than that of the hole is introduced into the hole so that a conductor track paste (3) applied to one side of the substrate is sucked into the hole or its edges by underpressure. The process is then repeated from the other side so that the two layers (3) overlap in the hole. In this way it is possible to line the holes perfectly, particularly even complicated configurations of holes. <IMAGE>

Patent DE-3220243-A1 (DE)
Title: Coin running track for automatic cash collectors
Inventor: BERGMILLER WALTER
IPC: G07F1/04
Filed: 1982-05-28
Abstract: Coin running track formed from an insertion chamber (1) and a deflection device (5) and intended for automatic cash collectors, especially coin-operated telephones. The deflection device (5) possesses guide plates (10, 11, 12) and guide tracks (6, 7, 8) which correspond to the different diameters of the coins and by means of which the coins are guided to the associated coin channels, and a running groove (9) common to the guide plates (10, 11, 12) and to the guide tracks (6, 7, 8). In automatic cash collectors designed in this way, the object is to prevent the possibility that improper coins having a somewhat smaller diameter than the proper coins will jam under the respective guide plate (10, 11). This is achieved in that there is arranged in the region of the guide plates (10, 11) adjacent to the running groove (9) a respective pivotably mounted lever (19, 20) which, in cooperation with a cutaway region (23) in the associated guide plate (10, 11), allows an improper coin to pass through. This prevents an automatic cash collector from being rendered useless by the insertion of a false coin. <IMAGE>

Title: Profiled body
Inventor: NAHR HELMAR DR DR
IPC: E06B3/267
Filed: 1982-06-04
Abstract: The subject of the invention is a profiled body which comprises two profiled rails, in particular such rails of metal, arranged at a distance parallel to each other. The profiled rails have undercut grooves on their mutually facing sides, into which grooves the connecting tongues of heat-insulating material are pushed. The connecting tongues are arrested in the grooves by a filling compound which is preferably expanded by foaming and then hardened. In order to ensure that little filling compound is required and the cavity between the profiled rails remains largely filled with air, an expansion barrier is to be provided, which prevents penetration of the filling compound at least into part of the cavity.
Patent DE-3222967-A1 (DE)
Inventor: FRASS WERNER DIPL CHEM DR
IPC: C25F5/00
Filed: 1982-06-19
Abstract: This invention pertains to a process for electrochemically modifying electrochemically roughened aluminum or aluminum alloy-based support materials for printing plates. An aluminum or aluminum alloy-based support material is electrochemically roughened using alternating current in an electrolyte containing at least one from the group consisting of hydrochloric acid and nitric acid. Subsequently, at least one surface of the material is treated in an aqueous electrolyte, with the roughened material being made the cathode. The cathodic treatment results in removal of material from the surface in the order of from 0.1 to 10 g/m2, and is carried out in an aqueous electrolyte which has a pH value in the range from 3 to 11 and includes at least one water-soluble salt in a concentration ranging from 5 g/l up to the saturation limit thereof. The cathodic treatment is appropriately conducted using direct current at a current density from 3 to 100 A/dm2, at a temperature from 15 DEG  to 90 DEG  C., and for a duration from 5 to 90 seconds. The removal of material is optionally followed by an anodic oxidation of the support material and a hydrophilizing post-treatment of the oxide layer. Support materials which have been prepared in this manner are used in the manufacture of offset printing plates carrying a radiation-sensitive coating.

Title: Show case having a front panel with hinged movement
Inventor: STENEMANN BRUNO
IPC: A47F3/00
Filed: 1982-07-01
Abstract: In a show case which serves for covering the goods offered in a sales cabinet, a front panel is made to be swivellable up and down by means of lifting brackets and a payment counter is positioned resting on horizontal supports. The lifting bracket consists of a panel holder which surrounds the front plate at the edges and is mounted rotatably on the support, and of a gas pressure spring which is received in the open profile space of the support having a U-shaped cross-sectional profile and is supported by one end on the support and by the other end on the panel holder. It is proposed for a simple, space-saving design, to arrange the panel holder next to the support offset laterally relative to the gas pressure spring and to mount it rotatably on the outside of the support side wall. Both the bolt for the rotary bearing and the hinge pin for the laterally offset gas pressure spring protrude at the front end of the panel holder.
