Patent DE-4210717-A1 (DE)
Title: Mfg. commutator contact plate with uniformly distributed grooves - sawing in planes parallel to envelope lines through two bodies bonded together after slight relative rotation
Inventor: PURBST DETLEF DIPL ING
IPC: H01R43/06
Filed: 1992-03-27
Abstract: Plates are formed from bodies of rotation assembled together so that one body (6) esp. of tungsten-copper alloy, shaped as a disc with grooves (5a) in its periphery, is fitted into the rim of the other body (1). In this position the two are braced together and grooved in a single operation. They are then rotated relatively through an angle corresp. to half of that subtended by the sum of the groove width and spacing for bonding together, e.g. with hard solder. The plates are sepd. by narrow saw-cuts in radial planes. ADVANTAGE - The plates, guaranteed to have practically   identical dimensions and tolerances, are more easily mfd. with high precision.

Title: Elastomer shock absorbing device - only allows return of piston as compressed elastomer expands again once piston has been relaxed.
Inventor: MENKHOFF KARLHEINZ
IPC: F16F9/30
Filed: 1992-04-29
Abstract: The piston rod (2) has a piston cover (4) containing a throttle bore (5) and fixed to the rod for sliding movement by a screw (6). The piston slides in the cylinder (8) so that the fluid compressible elastomer (7) is compacted as the rod enters, flows away through the bore (12) which is closed by a valve (10), and back through the first bore (3) into the cylinder. The cylinder can have one or more bores (12) opened and closed by the valves set in a valve ring (11) by turning an adjustment piston (13). The pretension of the elastomer (7) can be set by a pressure piston (14) located in the adjustment piston. USE/ADVANTAGE - Compared to oil damper of same structural size this system has better damping properties and can be used as damper or spring depending on its inner structure.
Patent DE-4215598-A1 (DE)
Inventor: HAUENSTEIN GUENTHER DIPL ING
IPC: G01F1/66
Filed: 1992-05-12
Abstract: A transducer is described for determining flow rates, in which the mean flow rate is determined with the aid of ultrasonic signals. The liquid flows in this case through a measuring tube (1), one transducer each being arranged opposite the ends thereof at both ends. The ends of the measuring tube (1) have arrangements which influence the flow profile of the liquid. These arrangements consist of webs (2), which represent an extension of the tube wall of the measuring tube (1) and between which there are present interspaces (3) through which the liquid passes. Each web (2) has a leading edge (4) and two separation edges (5). Such an arrangement generates irrotational eddies in the liquid which improve the accuracy of measurement, in particular in the range of small loads. Transducers of this type can also be used for calorimetry. <IMAGE>

Title: Charge accounting and identification of telecommunications terminal user - involves terminal reading identification number from inserted chip or magnetic card and transmitting number to telecommunications system for validation and charging
Inventor: HEUS HEINRICH
IPC: G07F7/00
Filed: 1992-07-07
Abstract: A personal identification number is stored in an integrated circuit (KS) on a plug-in chip card. When the chip card is inserted into the terminal device (T) the number is read and transmitted to a telecommunications system (PABX). The transferred number is compared in the telecommunications system with stored identification numbers to identify the user. When the number has been validated and service provided, a charge meter adds the charges incurred to a user specific charge account. A magnetic card could be used instead of a plug-in chip card. ADVANTAGE - Very simple and convenient telecommunications terminal device user identification and charge accounting.

Inventor: BARTELT BERTRAM
IPC: B01D29/48
Filed: 1992-07-09
Abstract: A backwashable liquid filter is provided. This has a filter element 17 mounted so as to be rotatable about its axis and through which the flow passes radially. In addition, a backwash device 18 is provided which has a dirt discharge channel 27 which runs in parallel to the axis of the filter element 17. The filter element 17 can be rotated within the filter housing 14 by a drive apparatus 23. When the filter element 17 is backwashed, purified liquid flows through the filter insert into the dirt discharge channel 28, removes the dirt particles adhering to the filter element and feeds these to the dirt discharge channel 27. For preliminary cleaning of the filter element 17, a spring-mounted scraper is provided upstream of the backwash device 28. This removes the coarse dirt situated on the surface of the filter element. <IMAGE>

Filed: 1992-08-11
Abstract: A colour video signal source represented as additive colour component signals R, G, B is first digitized 14, then converted to the complementary subtractive colour component signals C, M, Y by subtraction from a signal maximum 16. The number of sub-elements forming a pixel of the source signal is determined 18 and each that number of sub-elements stored as "ones" in C, M, Y memory 6 (figure 3). On read out, a pixel is determined as black by AND gate 8, and if a pixel is to be printed as black the inverting inputs of AND gates 10 inhibit the printing of a coloured pixel also to achieve undercolour removal. <IMAGE>

Title: Machining races for radial roller bearing - with outer race clamped and machined successively in orthogonal axes to provide offset ovality for inner and outer surfaces.
Inventor: HELMSCHROD GUENTER
IPC: F16C33/64
Filed: 1992-11-04
Abstract: To provide an even grip on the outer race when pressed into the retaining bore the ovality of the outer surface is at right angles to that of the inner surface. This is obtained by clamping, or stretching the ring alternately in the two orthogonal directions and machining the respective surfaces. The ring (1) is prepared from round stock by first stretching in one axis and machining the outside round. The inner surface is then milled after which the ring is stretched in the orthogonal direction and the outer surface milled round. After releasing the clamping the ring assumes the required shape. USE/ADVANTAGE - The shaped ring has an even hold when pressed into a cylindrical mounting recess.

Title: Method for monitoring the running thread at a winding station of an automatic winding machine
Inventor: HAASEN ROLF
IPC: B65H63/032
Filed: 1993-07-17
Abstract: For monitoring the running thread, it is conventional to use electronic cleaners which can generate a dynamic thread signal and a cleaner cut-in signal in the event of thread irregularities. The object is further to improve the monitoring of the running thread. For this purpose, according to the invention, a static thread signal is additionally generated and indicates only the presence of the thread in the measuring slot (presence signal). After the lapse of the static thread signal as a result of the exit of the thread from the measuring slot, an isolating pulse is generated. Advantageously, this isolating pulse is stored for a time and is triggered only when the winding process has not been interrupted as a result of other causes. Faults in which the thread has not run through the measuring slot can thereby be recorded. <IMAGE>

Abstract: The regulator (10) uses a processor (15) providing the mean output frequency of the drive regulator for each of a number of successive time sections during the winding operation. Each mean value is transferred to a memory (16) and used to calculate the required drive regulator output frequency for a subsequent time section. Correction of the required frequency is carried out in dependence on the detected tension applied to the wound material web to match the winding rate to the feed rate of the latter. Pref. The required frequency is obtained from the mean output frequency for the previous time section multiplied by a given factor of less than 1. ADVANTAGE - Ensures uniform around product. Space for dancer roller can be reduced.
