Title: Resilient bearing for seats mounted on tubular legs - includes eccentricities and stops allowing restricted forward and backward movement
Inventor: SAUER HANS LUDWIG
IPC: A47C3/026
Filed: 1974-03-01
Abstract: The actual seat of the chair is fixedly connected to a support which also has a fixed sleeve adapted to house the shaft of an eccentric, whilst a stop is rigidly attached to the anchor member by means of which the tubular leg of the chair engages in a biased spring rod of the support. When the seat has reached the angle of inclination set by the lever, the eccentric which is connected thereto abuts the stop which has a sharp-edged point so that any further undesired movement of the seat is prevented. To enable the seat to be inclined backwards and forwards, two eccentrics and two stops can be provided which are designed so that one end position lies in the horizontal position of the seat.

Title: Determining metal quality and hardenability - by conducting tests on cast blocks which are not subjected to plastic deformation
Inventor: BRANDIS HELMUT DR ING
IPC: G01N33/20
Filed: 1974-08-01
Abstract: Process is for determining the characteristics of metallic materials, esp. hardenability and transformation behaviour, strength and toughness. The examination is conducted on test-pieces obtd. from the stream of molten metal via a chilled mould, the test-pieces not being subjected to any plastic deformation and only being machined to the shape of test-piece required. Used, e.g. for determining the quality of steels. The results obtd. are independent of any influence due to plastic deformation and the test procedure is much simpler and less expensive as there is no need to forge or roll the sample prior to machining a test-piece. Instead of using e.g. a cast block 25 kg in wt. and hot working it prior to making a test-piece, a smaller cast block can be used for the test-piece with heat treatment in a conventional manner.

Title: Computer terminal optical display - is for showing continuously changing text
Inventor: PRAME ERIC SUNE
IPC: G09G3/28
Filed: 1974-08-13
Abstract: The technique allows a long text to be continuously displayed in an optical arrangement which is regularly up dated. The display is a row of alpha-numeric characters which appear to move from right to left, and these movements occur in discrete steps defined by a time-period generator. Each alpha-numeric character is formed by a matrix of individual lamps arranged to be 7 lamps high, by 5 wide, with a single row of 7 lamps high between characters. Thus, there may be up to 35 lamps per character, and the movement from right to left may be accomplished in steps of one fifth of a character at a time.

Title: Directional logic circuit for electronic electricity meter - delivers pulses whose frequency is proportional to electric power
Inventor: TSCHUMPEL HARTMUT DIPL ING
IPC: G01R21/133
Filed: 1974-10-23
Abstract: The pulses from the directional logic circuit pass through an AND gate for drawn and delivered energy, and are counted in corresponding separate counter. The measured variable voltage is applied after passing through a matching element to a comparator, whose output is applied through a differentiating element to the clock pulse input of a bistable D-flip-flop. The measured variable current is also applied after passing through a matching element to a differentiating element, whose output is connected to a comparator. The output signal of the latter prepares flip-flop data input. The flip-flop outputs control the AND gates in accordance with the energy direction of flow.

Title: Rotating and reciprocating electric motor - comprising generally concentric stator and rotor units has two magnetic systems
Inventor: KELLNER ECKHARD
IPC: H02K37/00
Filed: 1974-10-31
Abstract: The application is to machine requiring both rotary and linear drives, for example rotary and hammer drills and certain types of writing and printing machines. The motor comprises two magnetic systems, of which at least one is electromagnetic, which are arranged to be generally concentric one inside the other. By suitable electronically controlled switching the electromagnetic field of one section can cause rotation and/or linear motion in the other field. For example, an axial stack of stator windings, typically stepper motors, contains a permanent magnet rotor slightly longer than the axial length of one stator. By suitable diminishing the excitation on one stator, and raising it on the next axial motion at the desired rate results. By applying a rotating field to the stator rotary motion is achieved.
Patent DE-2453891-A1 (DE)
Title: Nail type anchor element with expansion sleeve - has driver pin with grooved spreader taper
Inventor: PETERSSON BENGT OLOF
IPC: F16B13/04
Filed: 1974-11-13
Abstract: A nail shaped tubular element has axial slots on each end. A blind hole which locates the driver pin reaches as far as the slot in the pointed end of the anchor element. The two halves formed by the trailing end of the anchor element are laterally offset so that it locates the stepped shoulder of the driver pin during installation. When completing the installation, the offset halves are pushed into a central position by the surrounding material. This allows the tapered driver pin to penetrate and expand the slotted end of the anchor element, thus creating a firm anchorage.

Title: Use of waste heat from nuclear or geothermal plant - by focussing in concave mirrors to generate higher temperatures
Inventor: HANSCHMANN HORST
IPC: F24V50/00
Filed: 1975-06-09
Abstract: A device for use in nuclear and geothermal power plants comprises a number of circular, flat vessels having opposite walls in the shape of convace mirrors, the vessels being inter-connected by pipes; waste heat in the form of steam, water of hot air is conducted through this system and the resultant heat generated at the focus of each concave mirror is absorbed by a steam-heating pipe, connected to a thermally insulated main steam pipe system. The main steam pipe system leads to a pressure storage vessel for steam where, when the necessary steam pressure has again been reached, the steam is passed, through the turbines, the waste heat then being recycled in the same manner. In this way, the thermal efficiency of the power plant is increased to more than 50%. In a variant, instead of steam pipes at the focuses of the mirrors to receive the heat, thermocouples are used, their ends being located in the waste heat or warm water lines.

Patent DE-2541022-A1 (DE)
Inventor: BORNWASSER HELMUT
IPC: B23K37/08
Filed: 1975-09-15
Abstract: Wire or profile ends to be welded are inserted into insert jaws (7) and welding clamp jaws (3, 4, 5, 6) of a left-hand, fixed (1) and a right-hand, movable (2) welding clamp device and are clamped in place. After the welding, the welding clamp-jaw pair (3, 4) of the movable welding clamp device is slackened and is displaced towards the still hot welding burr in order to remove the latter by means of the insert jaws (7) of blade-like design. This method can be used in resistance pressure butt welding or flash butt welding. Due to the quick welding and deburring sequence effected in only two operations, the welding clamp jaws (3, 4, 5, 6) and the insert jaws (7) are only slightly loaded and have very low wear. <IMAGE>

Title: Electromagnet with armature between two separate pole shoes - using electroless plated armature and shoe surfaces magnetically separated by spacer ring
Inventor: RICHTER HERMANN DIPL ING
IPC: H01F7/08
Filed: 1975-09-17
Abstract: The electromagnet comprises an armature which slides between two sleeve-like pole shoes which are magnetically separated from each other by a spacer ring. On the inner surface of the pole shoes and on the surface of the armature is a thin layer of magnetically non-conducting material which is applied chemically. The thin layers may consist of Ni or Cr, or the surface of the pole shoes may be nickel-plated and the surface of the armature Cr-plated. The thickness of the layers is pref approx 15mu. The Nilayers may be hardened thermally. The electromagnet may be used for control of the printing needles of a mosaic printer, because increases in stroke and wear of the tips of the printing needles by the printing process do not have a direct effect on the working life of the printer.
