Patent EP-0335105-A2 (EP)
Inventor: BLOTENBERG WILFRIED DR-ING
IPC: F04D27/02
Filed: 1989-02-22
Abstract: In the case of known control methods the intake volume flow to the compressor and the compressor final pressure measured after the compressor are included in the venting control. Disturbances in the through-flow which have their cause in a process downstream from the compressor are thereby only detected once they have spread through the compressor to the intake side. Under unfavourable conditions intervention by the venting control may therefore already be too late to prevent surging of the compressor. The new method is intended to rectify this drawback. 
<??>The new method proposes that in addition the delivery flow to the process downstream from the compressor be detected and taken account of in the venting control. This results in prompt reaction of the venting control to changes in the through-flow which are caused by the downstream process. 
<??>The new method is particularly suitable for the control of turbocompressors on which the downstream process is a possible cause of disturbances with changes in the through-flow.

Abstract: A franking machine with a thermal print head (27) incorporates a cassette (24) having a supply spool (28) and a take-up spool (30) between which is wound a ribbon (29) of thermally activable dye. An unwinding force is applied to the ribbon (29), and the take-up spool (30) is driven from the supply spool (28) through a slipping drive such as an elastic, slipping, endless band (32). The slipping drive tends to drive the take-up spool (30) at a speed high enough to maintain ribbon tension. The force applied to the ribbon (29) is produced by relative movement of the thermal head (27) and the article to be printed, with the heated ribbon (29) temporarily adhering to the article.

Abstract: Apparatus for monitoring the resistance of the return part of the patient circuit of either a dual foil or single foil return electrode (12) according to a user's selection is disclosed. The apparatus measures the quality of the contact between the return electrode and the patient. A DC to AC converter (21) provides a substantially DC voltage at its input that varies in relation to the resistance of the return part of the patient circuit at its AC output. Preferably, a constant current fed sinusoidal oscillator (25) with a low pass filter (L₁,C₃) at its DC output provides a substantially DC voltage related to the resistance at its AC input. An analog to digital converter converts the substantially DC voltage to a corresponding binary digital signal that is input to a programmed microprocessor. A manually operable set point switch coupled to the microprocessor is actuated by the user which actuation establishes a resistance level with the pad (return electrode) in place on the patient. The microprocessor establishes preselected range between fixed maximum and minimum resistance values beyond which an alarm output is produced and establishes a threshold resistance value whereby upon a preselected fixed deviation, such as when the patient pad is partially detached, an alarm is produced and further an output so the RF power source will longer apply power to the active electrode.

The elements are adjusted to one another and mutually fixed and welded together by laser equipment (13). Registering circumferential portions of the joint are exposed to two focusing optical devices (14, 15) which emit laser pulses or laser beams for the welding and form part of the laser equipment. The devices are aligned each towards one of two substantially registering, or slightly mutually offset, starting areas. Each respective area includes a section of each respective joint circumferential portion with circumjacent parts on the elements. The laser equipment is energized to emit, via the devices (14, 15), simultaneous or alternating laser pulses or laser beams, and the elements and devices are mutually influenced in respect of their movements such that laser output emission may be effected towards the starting areas and subsequent areas with associated sections of joint circumferential portions and material parts. By such means, a distortion-free joining will be attained.

Abstract: The object detection apparatus of the photoelectric reflection type is comprised of an optical source (2) for generating an optical ray, an optical incident system (3) having an optical axis extending through an observation zone in a direction of its definite observation range for directing the optical ray along the optical axis, and an optical collecting system (5) for collecting the optical ray reflected by the object (4) which traverses the optical axis to focus on a receiving area (6) an optical spot, location of which depends on an axial distance of the object. Further, a definite photosensor is disposed to cover a part of the receiving area and operates only when an object enters into the observation zone within the observation range for detecting an optical spot within the covered part of the receiving area, and an output circuit is connected to output an object detection signal only when the photosensor detects the spot. Preferrably, the definite photosensor has a sensing face extending between one edge registered with a spot which corre­sponds to the farthest end of the observation range and another edge registered with another spot which corresponds to the closest end of the observation range. Further preferrably, the optical source includes a photoemitter for intermittently emitting a pulsive optical ray in response to a sampling signal, and   the output circuit operates to produce successively a sampled data according to the intensity of the detected optical ray and to calculate a relative change between preceding and succeeding sampled data so as to output the object detection signal, when for example the object passes between the detection apparatus and a reflective background surface.

Abstract: In the encoder an audio input signal is firstly given an adaptive pre-emphasis characteristic by a pre-processing circuit (16) and is then converted to a digital signal for transmission by a delta-modulator (22). In order to minimise the digital bit rate the delta-modulator (22) is rendered adaptive by deriving a step-size control signal in a circuit (18) responsive to the slope of the input signal, and applying the control signal to vary the step size of the delta modulator (22). The bandwidth of the control signal is limited to say 50 Hz by the step-size circuit (18) itself or a subsequent low pass filter (24) in order to render the encoder insensitive to random step-size errors. The slow response of the control signal is compensated for by a delay circuit 20 preceding the delta-modulator (22). The corresponding decoder comprises an adaptive delta-demodulator and a circuit complementary to the pre-­processing circuit (16). In order to keep the decoder as simple as possible it has no step-size derivation circuit. Instead, the step-­size control signal is transmitted in conjunction with the main digital signal by way of an analog to digital converter (26). In the encoder a complementary digital to analog converter is followed by another bandwidth limiting filter to reduce the effect of transmission bit errors. The slow response of the decoder control signal is compensated for by transmitting the step-size information from the encoder with a time advance relative to the main digital signal.

Abstract: Device for correcting vertical frame adjustment errors when replaying an intermittently transported, perforated cine film by means of a film feed sprocket engaging in the film perforation and driven by an electric motor whose rotor is connected to a phase-angle sensor device which transmits positional signals corresponding to the angular position of the rotor to a controlling system driving the electric motor. In order to correct equipment-specific vertical frame adjustment errors, the frame positions are measured using a geometrically exact test film over a multiplicity of frames, the respective frame positions are stored and the position of the phase-angle sensor plate is varied by a correction value with respect to the film feed sprocket. In order to correct vertical frame adjustment errors that depend on operation, error tables are stored for frame errors occurring during projection operation, the frame positions are continuously measured and the measured values acquired are compared with the values stored in the error tables, an error table optimally representing the measured values is determined, and a correction table is selected which pertains to said error table and whose correction values are transmitted to the controlling system.
