Patent DE-2737201-A1 (DE)
Title: Measuring instrument with automatic range selection - includes signal variation in time displayed on CRT which also displays digital values
Inventor: TICHAWA MICHAEL
IPC: G01R13/22
Filed: 1977-08-18
Abstract: The instrument has A/D convertors for digital displays of several characteristic parameters of a voltage and for visual display on a CRT of its variation in time. Figures are also displayed on the CRT screen. Signal flow generated by the input voltage (U1) is applied from a measurement input (1) to a number of channels (2, 3) equal to or smaller than the number of parameters to be measured. Channels (2, 3) operate independently from each other and comprise circuit groups (21, 31, 33) whose output voltages are functions of the input voltage determined by the parameter measured in the respective channel. These signals are applied to A/D converters (23, 34). A voltage alternating component is applied to a built-in CRO as analogue voltage.

Title: Dynamometer cell type lever balance - uses three fulcrums acting on crossbar which acts on dynamometer cell
Inventor: FRICKE HERBERT DIPL PHYS
IPC: G01G21/02
Filed: 1977-08-18
Abstract: The balance is designed to permit application of a force, proportional to a load, via a crossbar (5) to a dynamometer unit (7). At least a pair of opposite facing levers act, via at least three fulcrums (8, 13, 9) in a plane, on the crossbar. The crossbar acts without reduction directly on a dipiamometer cell via a curved part of the fulcrum system. One fulcrum (13, 14) associated with a load lever (1), on the crossbar (5) is situated between fulcrums (8, 9, 11, 12) associated with the other load lever (2). The arrangement of the fulcrum bearings is symmetrical with respect to the point of application of the forces on the dipiamometer cell. The lower part of the fulcrum bearings are curved and rest on a compensation plate (15) which is connected to the crossbar via a multiple ballbearing support (16).

Title: Series condensing system for multistage turbine plant - has condensate from one stage injected into exhaust of next stage
Inventor: SUHARI LASZLO
IPC: F01K9/00
Filed: 1977-08-19
Abstract: Two low pressure turbines (1, 2) are supplied from a common source (3) and drive a common generator (6). The exhaust from each flows through a condenser (11, 12). Cooling water (18) flows through the two condensers in series. The condensate (14) from the condenser (12) which receives the coldest cooling water is pumped into a sparge pipe (20) through which it is injected into the exhaust entering the next condenser (11) in the series. The cooling water leaving the first condenser enters this condenser. The arrangement improves the cooling in the second condenser which is served by higher temp. cooling water and increases station efficiency.

Title: Tipped drill bit for reinforced concrete - has surface hardened shaft with brazed-on hard alloy cutting inserts
Inventor: BREITING JOHANNES
IPC: B23B51/02
Filed: 1978-03-02
Abstract: The drill bit for drilling concrete can also penetrate steel reinforcement. The bit has a centre angle between 120 and 125 degrees and a setting angle between 10 and 15 degrees. The bits can be used also for glass, ceramics and similar materials provided the correct speed is selected. The drill operates satisfactorily for concrete at a speed of 2000 rpm, while with percussion action the drill should be operated at 100 rpm. The effectiveness of the bit is increased by providing the shaft with surface hardening which reduces vibration during drilling as well the detrimental effects of excess heat expansion.

Title: Air drier for car wash - uses portal type structure and uses water with additive to form droplets on car for simple removal
IPC: B60S3/04
Filed: 1978-08-07
Abstract: The modified car wash equipment (1) has a portal which makes several passes over the vehicle. The washing process occurs in the first pass followed by a rinsing pass. The rinsing water collects in droplets after addition of a surface tension enhancing additive so that the last pass can blow the vehicle dry with a moderate airstream. The additive can be replaced by an electrostatic treatment of the car plant to aid the formation of water droplets. The system allows a quieter fan to be used for the blower.

Title: Controlling carbonate hardness of water for use in brewing - by removing carbonate by ion exchange and stripping, and filtering through calcium carbonate
Inventor: GRUENBECK JOSEF
IPC: B01J39/04
Filed: 1978-10-04
Abstract: Controlled redn. of the carbonate hardness of water is effected by (a) passing the water over an acidic cation-exchanger, (b) stripping off unwanted H2CO3 with a counter-current air stream, and (c) filtering the water through a porous CaCO3 material. The appts. comprises an ion-exchange column, a trickle column for stripping with air, and a filter. In one embodiment, the air flow through the trickle column is controlled in response to the carbonate hardness of the water leaving the filter. The process avoids the complicated processing described in DT 1253182.

Title: Clockwise-anticlockwise twisting machine for electrical cables - has twisting path doubled back on self via deflection rollers to reduce overall length
Inventor: VOGELSBERG DIETER DIPL ING
IPC: H01B13/04
Filed: 1979-01-08
Abstract: The path along which the cable travels through the machine is divided into several sections located in different parallel planes (a-d). The sections are joined one to another by deflection rollers (14) that turn the cable through 180 deg. back on itself. These rollers allow the cable to rotate about its axis along the sections. In the first section the cable rotates e.g. clockwise, in the second anticlockwise, in the third clockwise and so on. The wires (1) making up the cable enter the machine via separate rollers from their storage drums (7) and are brought together by the input nipple (10). The grouped wires then pass into the first twisting section of the machine. High production rates can be accomplished and the machine has a relatively short length whilst still allowing large distances of up to 500 or 1000 m between the points at which twisting direction reverses. The machine is intended for making flexible cables that will be cut into relatively short lengths before use.

Title: Data and writing recording arrangement for camera - has single band symbol carrier moved by transport mechanism for positioning of selected symbols
Inventor: STRAUCH SIGMAR
IPC: G03B17/24
Filed: 1979-03-26
Abstract: The photographic information recording system enables an indefinite number of symbols - even a whole sentence - to be printed next to an associated frame. It can be used even after the actual picture has been taken. It can be built into the camera pref. for recording the information on the edge of the film surface. The information or writing is recorded by light beams passing through a symbol carrier inserted in front of the film frame surface to be exposed. The symbol carrier consists of a single band movable in front of the image surface for positioning of the desired symbols. A transport arrangement is provided for this purpose. For the recording of one or more lines the symbol carrier is movable to and fro at right angles to the direction of movement of the transport and in parallel to the image surface of the film.
