Patent NO-177612-B (NO)
Inventor: HECKLER MARK
IPC: E05F15/14
Filed: 1990-10-19
Abstract: By means of this method and the arrangement, in the case of an automatic door, especially in the case of lifts with a controlled door drive which moves doors of a cabin door by means of a motor with a reduction gear and a mechanical drive, and moves doors of a shaft door via mechanical coupling elements, protection against being caught, responding up to the last few mm of a door closing movement with constant force levels, is provided. In this case, this is done by a control error dV being continuously compared during the door closing movement with a maximum permissible control error dVmax produced by a nominal value sensor (3.5) and, if this maximum control error is exceeded, the door is stopped with subsequent reversing. The response levels for an external disturbing force (3.9) are kept constant by a calibration trip computer (3.11) determining values for mass compensation (3.12) and values for friction compensation (3.13) during periodic calibration trips and supplying these values as a compensation value Vk to a second comparator (3.2). In consequence, the magnitude of an external disturbing force (3.9) is also known, or can be measured precisely, with a defined gain of the controller (3.8) and a known torque characteristic of the DC motor (2.1), which creates the precondition for safe protection against being caught.

Abstract: 1,008,937. Stereophonic radio signal receivers. RADIO CORPORATION OF AMERICA. June 6, 1963 [June 19, 1962], No. 22661/63. Heading H4L. In a stereophonic radio signal receiver for a signal of the type which includes a pilot signal for regenerating a harmonically related subcarrier for demodulating purposes, the circuit for providing the harmonically related subcarrier includes a class C amplifier having an input circuit coupled to a pair of diodes acting as a full-wave rectifier in the output of a resonant circuit selecting the pilot signal and an output circuit tuned to the subcarrier frequency, the amplifier being provided with selfbiasing means so that it conducts only at the peaks of signals applied thereto. As shown in Fig. 1, the output of the F.M. detector 8 is supplied via an amplifier 23 to an amplifier 18 having an anode circuit 36 tuned to select the 19 kc/s. pilot signal. The pilot signal is frequency-doubled by a full-wave rectifier circuit 39. The 38 kc/s. signal developed across resistor 44 is supplied to the class C amplifier 47 and the anode circuit 58, tuned to 38 kc/s. supplies the regenerated subcarrier as a switching signal to the demodulator 57. Cathode bias circuit 55, 56 ensures that the bias is self-regulating as a function of pilot signal amplitude to improve the phase stability of the 38 kc/s signal. A neon tube 33 lights up only in the presence of a pilot signal to indicate stereophonic reception. A filter 66 selects the L-R sidebands, and provides high-frequency de-emphasis, and rejects an additional unrelated signal which may be present on a 67 kc/s. subcarrier, the L-R signal being supplied to the demodulator 57. The demodulated L-R signal is supplied to a phase splitter valve 74 so that + (L-R) is developed across resistor 79 and - (L-R) is developed across resistor 80, and the L+R signal is fed from a potentiometer 31 to the junction of resistors 79, 80, via a de-emphasis network 86, 88, the resulting L and R signals appearing at terminals 16 and 17 respectively. During monophonic reception there is no output from the class C amplifier 47 thus providing automatic change-over from stereophonic to monophonic reception and a reduction of noise.

Filed: 1986-03-24
Abstract: A pix-in-pix television display includes circuitry for reducing the amount of memory needed to hold one field of the reduced size image. In the display apparatus, digital samples representing the large and small picture signals are developed at substantially equal rates by separate circuitry. Subsampling circuitry stores one out of every five of the samples representing a horizontal line of the small picture. These samples are displayed, synchronous with the large picture at a rate three-fifths times the display rate of the large picture samples to produce an apparent size reduction of one-third in the horizontal direction.

Patent ZA-917329-B (ZA)
Title: Method and apparatus for improving vertical sharpeness of picture tubes
Inventor: HACKETT ANDREW DENYS
IPC: H04N3/32
Filed: 1991-09-13
Abstract: Large format TV tubes must produce a high peak brightness in order to be acceptable to the user. This results in a large beam current in bright areas of the picture and in a subsequent defocusing of the resulting spot on the display and in a loss of the sharpness of vertical and horizontal transitions. The apparent sharpness of a vertical transition is gained by modifying the deflection of the TV receiver such that, at vertical transitions, the line on the bright side of the transition is deflected away from the transition region. Advantageously, the amount of vertical scan modulation corresponds to a multi-level control signal and depends on the grey levels of the transition.

Abstract: This wheel hub assembly is intended for the driving set of wheels of a vehicle which may be steering wheels or otherwise. It comprises mainly a wheel flange, a transmission joint and a rolling bearing. The axial bearing surface between the flange and the inner race of the rolling bearing is limited to an annular ring of small radial dimension but of relatively large diameter. The section of the passage of the flow of heat between the flange and the race is thus substantially reduced.
