Title: Device for the electrostatic deflection of discontinuously produced, contrasting fluid droplets for an ink jet printer
Inventor: ZWEIGLER WOLFGANG
IPC: B41J2/095
Filed: 1982-11-26
Abstract: The invention relates to a deflection device for ink jet printers whose primary objective is to compensate the influence of the path covered by print fluid droplets after the deflection pulse has occurred on the deflection of said droplets and to utilise the by far the greatest part of the image droplets for the formation of characters in order to achieve a high printing frequency. The invention is therefore based on the object of developing a deflection device in which a droplet-by-droplet digitisation facility of each droplet position is provided using the line-drawing method and the resulting droplet deflection is dependent merely on the deflection voltage and the deflection pulse duration, but not on the location at which the printing fluid droplet is located at the time of the pulse effect. According to the invention, for this purpose the deflection electrode plates are arranged obliquely with respect to one another, their spacing decreasing from the side of the droplet inlet to that of the droplet outlet and being proportional with respect to the remaining length of trajectory. The application of the invention is expedient in non-mechanical typing and printing technology. <IMAGE>
Patent DE-3306979-A1 (DE)
Title: Indicating instrument
Inventor: WRIGHT GRAHAM BOOTH
IPC: G01D13/14
Filed: 1983-02-28
Abstract: In an indicating instrument having a pointer and a circular dial, the scale values are indicated by digital indicating panels which are arranged at equal distances along the dial. The series of scale values reproduced by the indicating panels in each case corresponds to the instantaneous measuring range indicated by the pointer. If, for example, the indicating panels indicate the values 0 to 45, the indicating panels opposite to the pointer change their indicating values to 50, 55, 60 etc. when the pointer has swept over the first half of the dial in a rising direction. If the indicating panels indicate the values 100 to 55, the indicating panels opposite to the pointer change their indicating values to 50, 45, 40 and so forth when the pointer has swept over the second half of the dial in a falling direction.

Title: Electrical flush-mounted socket, designed as a hollow-wall socket, such as a switch socket, junction socket or the like
Inventor: FREUNDNER HASSO
IPC: H02G3/12
Filed: 1983-03-16
Abstract: An electrical flush-mounted socket, designed as a hollow-wall socket, such as a switch socket, junction socket or the like, which consists of two parts, namely an approximately annular insertion body and a housing, and which can be inserted in the opening in a wall and has at least one supporting flange. It is furthermore equipped with means for connecting the two parts to one another and to fix the flush-mounted socket in the region of the opening in the wall. In order to create the possibility of providing the rearward part of the housing with a different design, the insertion body is inserted from the rear into the opening in the wall. The housing is inserted into the insertion body in the same direction, that is to say likewise from the rear with its open side in front. In consequence, only the front region of the housing need be matched to the dimensions and design of the insertion body. The design of the rearward housing part is completely free.

Patent DE-3331091-A1 (DE)
Title: Joint endoprosthesis
Inventor: LAACK WALTER VAN DR MED
IPC: A61F2/30
Filed: 1983-08-29
Abstract: Complete or partial joint endoprosthesis whose mutually articulating parts each comprise hollow bodies with windows which furthermore consist of the materials already employed for endoprostheses, e.g. metal alloys, plastic or ceramic compounds, which are completely or largely filled with an absorbable material which biologically resembles bone and can be replaced by bone, e.g. calcium phosphate ceramics based on tricalcium phosphate (3 CaO . P2O5), thus permitting growing in of the joint endoprosthesis in the bone as completely as possible. The above-described principle of construction can be refined still further in all prosthetic parts in that the shaping prosthetic materials are additionally coated on their inside firmly with the calcium phosphate ceramics with which they are filled and, applied as a firm layer to the outside where appropriate, permit steady attachment of the bone material to the prosthetic parts. Already existing surface enlargements, e.g. by knobs or pores, may represent an additional optimisation. The object is much more durable, cementless fixation of this new type of prosthesis in the bone seating.

Title: Turbine machine
Inventor: CAROLUS THOMAS DIPL ING
IPC: F01D7/00
Filed: 1983-11-30
Abstract: The invention relates to a turbine machine whose pressure/mass flow or pressure/volume flow characteristic curve is no longer defined, as hitherto, by the shape of the turbine machine and the rotational speed of the rotor. However, instead, a regulating device associated with the turbine machine, for example a vortex apparatus (7), a rotor blade adjusting device or a throttle is continuously adjusted by a control unit (9), on the basis of the signals of a detector (12) for the pressure or the mass flow or volume flow and of a position transmitter (11) indicating the instantaneous position of the regulating device, in such a way that the turbine machine has a pressure/mass flow or pressure/volume flow characteristic curve which is entered into the control unit (9) and which is selected at will. <IMAGE>

Title: Method for minimising the operating costs of heat pumps in the heating of buildings
IPC: F24D3/18
Filed: 1984-05-30
Abstract: Method for minimising the operating costs of heat pumps in the heating of buildings by in each case supplying to a heat pump with an evaporator, which is equipped for heat transfer from heat-transfer media in gaseous (5) and liquid (12) phase, the heat-transfer medium with the higher temperature at the time for the purpose of achieving the optimal performance figure, a temperature-controlled automatic control (3) carrying out the control of the necessary shut-off devices, such as flaps (4) and valves (14), fan (10) and pump (13). Provided that the outside air (2) has a lower temperature at the time than can be provided by a circulatable medium such as air or water/brine, a switch-over is made to such an installed medium and in the opposite case back again. Circulating air or circulating liquids absorb in this case earth heat or direct solar heat, to which end they are conducted through corresponding hollow bodies such as ducts (6) or pipes (7, 11) and devices such as absorbers. Heat can also be removed from heat accumulators in this manner. For the purpose of a further improved performance figure, a rotary compressor is used, which, for the purpose of increasing the performance of the heat pump, can be heated by liquids or waste gases, the temperature of which is correspondingly controlled. Alternatively, the hot medium is if necessary reheated, e.g. electrically or by a gas geyser, directly after the liquefier. <IMAGE>

Title: Device for filling a telecommunications cable
Inventor: KNOCH ROLAND DIPL ING
IPC: H01B13/32
Filed: 1984-05-30
Abstract: In the case of a filling device (10) which consists of a filling chamber (11) and two sealing tubes (12, 13) which are used as inlet and outlet, the cross-section deviates from the cylindrical cross-section at least on one part (14, 15) of the length of the sealing tubes (12, 13). The deviating cross-sections are elliptical, or have shapes adapted to the core cross-sections. This change in the cross-section causes a more powerful fulling process during fitting of the core (9), as a result of which the position of the individual strand elements is temporarily changed. This facilitates the penetration of even highly viscous filling compound into the smallest gap between the wires. <IMAGE>
