Title: Inductive control system for railway vehicle - includes phase difference equalising circuit for line conductors at points and crossings
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: B61L3/22
Filed: 1980-08-23
Abstract: The track control system for railway vehicles fitted with inductively coupled aerials includes a system for equalising a phase discontinuity at points, crossings etc. A permissible phase difference is monitored in the inductive line conductors to which the aerial is coupled, these conductor sections being of different lengths. They form supply and return paths at the crossing point. The longer section is thus detected, and an equalising circuit is introduced by means of concentrators such as inductances, resistances or capacitors. The wiring for the section forms a loop with an inductance or two inductances in series with a capacitor connected to their junction point at line potential. Alternatively, the loop can consist of two ohmic resistances between two inductances, with a parallel capacitor and resistance connected to the central junction point.

Title: Heat exchanger with coaxial inner and outer tubes - has relatively small gap for flowing medium
Inventor: REISEWITZ GUENTER
IPC: F24S10/70
Filed: 1980-09-30
Abstract: Heat exchanger tubes for a fluid medium each have an outer tube contg. a coaxial inner tube, with an annular gap. At both ends each outer tube is joined to a transverse tube for feeding the medium into the tube assembly. The distributor tube may also act as a support for the inner tube. When they project beyond the distributor tube the inner tube ends may have a closure cap, or if projecting beyond a first distributor tube may terminate in a second tube for a further fluid medium. Used for collectors of solar heat or ground heat. The vol. of fluid for heating is reduced, giving faster temp. rise, and there is no air gap acting as insulation.

Title: Metal crucible cooling process - uses metal in coolant chamber dissipating heat by solidification during intervals between melts
Inventor: FLECHER PIERRE DR ING
IPC: F27D9/00
Filed: 1980-10-23
Abstract: The process cools intermittently-used metal crucibles each having a coolant chamber and one or more recesses for the melting of ring- or bar-shaped samples under vacuum or a protective gas. A cooling metal with a melting point between 60 and 400 deg.C is introduced into the chamber, and the melting operation is started with this metal still in the solid state. Absorption of the melting heat by the metal is used to store some at least of the heat applied to the crucible during melting, this heat being dissipated to the surroundings by solidification of the metal during the intervals between melts.

Patent DE-3100102-A1 (DE)
Title: Profiled-sail system for propelling craft
Inventor: BECKER ANDREAS
IPC: B63H9/06
Filed: 1981-01-03
Abstract: For propelling boats and ships, if need be also land craft, by wind force, cloth or plastic sails are normally used. Water craft with sails of this type require, for example, numerous operating persons for setting the sails, are very restricted in their operating area to the wind and have a poor ratio of propulsion force and drift force. The said problems are solved in particular owing to the fact that profiled sails (rigid sails with aerodynamically favourable shape; see Figure, items 20a and 20b) are connected to the mast (item 1) at a distance from it and are pivotable about horizontal sail pivots (item 3). The pivoting capacity enables the curvature directions of the profiles to be reversed by rotating the profiled sails through 180 DEG about the sail pivots, which enlarges the operating area to the wind compared with other sail systems. To disengage the wind propulsion, the profiled sails are turned through 90 DEG  about the sail pivots. All rotary movements of the profiled sails can be carried out fully automatically since the profiled sails are of rigid design. <IMAGE>
Patent DE-3103622-A1 (DE)
Title: Camera having shutter speed control
Inventor: UCHIDOI MASANORI
IPC: G03B9/08
Filed: 1981-02-03
Abstract: The invention relates to cameras, and in particular to the type of camera having a drive source which upon being supplied with electric energy outputs a drive torque to move the shutter device, and in which the operation of the shutter is controlled by the drive torque of the drive source. In such cameras, there is the need for the voltage applied to the drive source to be greater than a specific value; otherwise, the shutter curtains cannot be driven to move at a constant normal speed. For this reason, it is impossible to control the shutter time accurately when the battery voltage is below a specific value. This has a great influence, in particular, when the shutter speed is short, the result being an increase in the error in exposure. According to the invention, a camera is provided which as a result of the lowering of the battery voltage below the specific value explained above changes the shutter speed to a specific higher value, so that the error in exposure is limited to a value which is as small as possible, even if owing to the lowering of the voltage the rate of travel of the shutter curtains is, as explained above, no longer accurate, as a result of which usable photographs are possible.

Title: Moulding device for plastics
Inventor: KURAMOCHI HIROSHI
IPC: B29C45/02
Filed: 1981-03-02
Abstract: The invention contains a moulding device for producing sprue-free moulded parts as a consequence of a precise surface mating of a pair of moulds. The moulding device comprises an upper holding element for fixing at least one upper mould with a channel into which a mouldable material is to be introduced, and a lower holding element for fixing at least one lower mould with a cavity, the aim being to fill a specific amount of fluid between a base surface of the lower mould and the lower holding element. In this manner the lower mould floats on the fluid and is movable along the lower holding element. After surface mating is effected between the base surface of the upper mould and the upper surface of the lower mould, precise mutual contact results as a consequence of back pressure of the fluid. <IMAGE>

Title: Device for coupling an infrared diode to an individual glass fibre used as an optical waveguide
Inventor: PLIHAL MANFRED DR
IPC: G02B6/42
Filed: 1981-06-02
Abstract: The device for coupling an infrared diode to an individual glass fibre used as an optical waveguide has a coupling sleeve into which it is possible to insert from one side a cylindrical pin which contains the end section of an optical waveguide, and from the other side a diode base having a diode attached to the end face thereof. The plug-in depth of the pin, which is limited by a collar on the cylindrical pin, is dimensioned such that starting from a desired value it can only be smaller by up to approx. 40  mu m than the desired value. The diode base is designed in such a way that the minimum distance from the diode end face to the collar of the cylindrical pin which acts as a stop when said pin is inserted into the coupling sleeve is at least 10  mu m larger than the desired value, but exceeds the desired value by at most 20  mu m. This ensures in an uncomplicated way that the end face of the cylindrical pin is entirely unable to contact the diode and risk damaging it.

Patent DE-3143656-A1 (DE)
Title: Compass saw, in particular for dividing flesh, with a fixed saw-blade guide part and a saw blade guided therein which can be driven in an oscillating manner by a drive
Inventor: SYRE MANFRED
IPC: A22B5/20
Filed: 1981-11-04
Abstract: The invention relates to a compass saw which is required in butchers' shops for dividing flesh into transportable pieces or pieces suitable for consumers. The saw blade driven in an oscillating manner slides in a fixed saw-blade guide part. Since both parts are made of the same material, the friction which occurs leads to a high build-up of heat and to high wear. It is therefore necessary frequently to change both parts despite low cutting speeds during operation of the saw. In the compass saw according to the invention, a guide rail made of a plain-bearing material is arranged between the saw-blade guide part and the back of the saw blade. Consequently, a substantial reduction in the friction occurs so that, on the one hand, the life of the saw blade and also that of the saw-blade guide part are substantially longer and, on the other hand, the compass saw can be operated at a substantially higher cutting speed. In the saw according to the invention, it is merely necessary to change the saw blade, which may only be necessary if the cutting teeth of the saw blade are worn. <IMAGE>

Title: Detachable fastener for attachment of dental impressions to pivotable mountings
Inventor: BECKWITH EDWARD K
IPC: A61C11/08
Filed: 1982-03-16
Abstract: A detachable fastener with which dental impressions can be attached to a pivotable mounting comprising a lower part or bracket which can receive a lower mouth model and an upper part or bracket which can receive the upper mouth model. A layer of a cured binder is formed on each of the lower and upper parts directly on the associated mouth model, and the detachable fastener has a first connection device having an annular peripheral transition collar of predetermined length and predetermined diameter, from one end of which a spherical connection element projects axially and from the other end of which an enlarged base element projects axially, and a second connection device with a holder housing which consists of an elongate, thin-walled, tubular element having an opening on one end which extends through the interior of the holder housing, the opening being able to receive the spherical connection element and to guide it to the interior of the holder housing and the holder housing having means which form an annular peripheral aligning and gripping element having an oblique edge in the inner wall of the thin-walled element near the opening, which edge extends from the edge of the opening inwards to the interior of the holder housing, so that a spherical connection element inserted in the opening of the holder housing is brought into contact with the aligning and gripping element and guided past the latter until the oblique edge of the aligning and gripping element engages behind the connection element approximately at the point where the spherical connection element merges into the transition collar. If a separating force is exerted in one direction, so that the first connection device is pressed away from the second connection device, the spherical element comes abruptly out of engagement with the aligning and gripping element so that the spherical connection element can be removed from the holder housing and the mouth model can be detached from the pivotable mounting. Furthermore, a method is provided for production of a device for reception of dental impressions on a pivotable mounting.

Title: Process and device for the unwinding of yarns from bobbins
Inventor: WOLF HORST DIPL ING
IPC: B65H49/26
Filed: 1982-04-17
Abstract: In order to connect the yarn of a running-off bobbin to the yarn of a reserve bobbin also on bobbins, from which the yarn is drawn off tangentially and which are therefore rotated during the draw-off of yarns, and thus to allow an uninterrupted drawing off of yarn, the reserve bobbin is made to participate in the rotation of the feed bobbin, to the yarn ends of which the yarn start of the reserve bobbin is connected. For this, there are couplings, by means of which the tubes of the bobbins can be coupled rotationally. Couplings both arranged fixedly on the tubes of the bobbins and designed as a separate component are proposed. <IMAGE>

Title: Arrangement for eliminating reflection from displays
Inventor: ZIEGLER WOLFGANG DR
IPC: G01D13/00
Filed: 1982-09-08
Abstract: An arrangement for eliminating reflection from displays, particularly liquid crystal displays, is proposed which is used, in particular, in motor vehicles. An antireflection panel with a polariser is arranged obliquely in front of the liquid crystal display. To achieve a particularly strong suppression of the reflection, an antireflection layer is applied directly in front of the liquid crystal display. In another arrangement, it is proposed to arrange a circular polariser obliquely in front of the liquid crystal display. Both measures make it possible to reduce interfering reflections to less than 1%. <IMAGE>
Patent DE-3236804-A1 (DE)
Title: Nail correction clasp
Inventor: WINTER ROBERT
IPC: A61F5/11
Filed: 1982-10-05
Abstract: The nail correction clasp is a resilient steel strip (Fig. 3) of a length necessary for the respective width of a toe nail, a rubber profile (Fig. 4) being pushed on at each end. These rubber profiles are then affixed to the two nail ends lying opposite each other (Fig. 5). In the case of nails which are very considerably arched and ingrown, it is also possible first to affix these rubber profiles to the respective nail ends lying opposite each other and then to introduce the resilient steel strip (Fig. 5). This results in an upward levering action on both ends of the nail, as a result of which the ingrown nail is gradually raised from the depression of the nail bed and, thus, leads to flattening of the nail and of the nail bed. <IMAGE>
