Title: Sliding door top guide
Inventor: JACOBS KENNETH
IPC: E05D15/06
Filed: 1997-02-11
Abstract: A guide for a sliding door provides both ease of installation and improved resistance to unintended disengagement from the guide track 100. The guide comprises a bracket adapted for attachment to the door, an outer guide member (fig.2) slidably seated in the bracket and an inner guide (fig.4) slidably seated in the outer guide member. A first lip 85 on the outer guide member cooperates with a closely adjacent second lip 76 on the inner guide member to slidably engage the guide track 100. The two lips face in opposite directions and engage the insides edges 101,102 of the track. The second guide member is seated in the first guide member in a manner such that movement of the inner guide member outwardly of the bracket, causes the first lip 85 to move away from the second lip 76 to engage the guide track more securely.

Title: A friction clutch with a simply assembled automatic wear adjuster
Inventor: BOKISCH WINFRIED
IPC: F16D13/75
Filed: 1997-03-21
Abstract: A friction clutch 1 comprises an automatic wear adjuster 3 having ramped adjusting elements 18, 19 which are radially guided by guide pins 17. The adjusting elements 18, 19 are circumferentially urged, for example, by springs 26 coiled at one end around guide pins 17 so that the springs 26 also aid in guiding the elements 18, 19 (see figs 5a, 5b). When the clutch is engaged heads 16 of sliding pins 14, which are jammed in bore 20 by spring 9, contact counter-pressure plate 2 such that any gap between levers 15 and diaphragm spring 7 is filled by elements 18, 19. As friction linings 4 wear, pressure plate 5 moves towards counter-pressure plate 2 and the action of spring 7 relieves the jamming engagement of pins 14 and a gap appears between levers 15 and spring 7. On clutch withdrawal the spring 7 moves away from plate 5 and springs 26 cause relative circumferential movement of elements 18, 19 so as to take up the gap between plate 5 and levers 15. In another embodiment a hairpin spring may be used (see figs 2a, 2b).

Title: Transformerless audio power amplifier using pentodes
Inventor: DAVIS ROGER
IPC: H03F3/181
Filed: 1997-10-23
Abstract: A high fidelity power amplifier using thermionic valves and incorporating a direct output circuit configuration based on two pentode valves which has a low electrical output impedance at audio frequencies. Fig 1 is a schematic diagram of the basic direct output configuration. V1 is a cathode follower, modified to include a resistor anode load of 68 ohms, and using another similar pentode valve V2 as the cathode load. The signal appearing at V1 anode is coupled to V2 control grid, thus effectively modulating V1's cathode load in such a way that power which would otherwise be wasted in the passive resistor cathode load of a conventional cathode follower is diverted to the loudspeaker. Fig 2 shows the invention in association with conventional valve amplification techniques to produce a power amplifier without an output transformer which will drive suitable hi-fi loudspeakers, giving very high quality audio reproduction.

Title: Voltage reference generating device
Inventor: ODA TOSHIAKI
IPC: G05F1/56
Filed: 1998-01-30
Abstract: A reference voltage generating device, aids rapid rising of a reference voltage while preventing wraparound of power source noise after rising of reference voltage. An electric supply circuit 3 is connected to a reference voltage output terminal of a reference voltage generating source 1. During a prescribed time from power ON, charging current is directed toward a load capacitance attached across the reference voltage output terminal A and ground. Thus, the reference voltage rises rapidly. After rising, the electric charge supply circuit 3 is disconnected from the reference voltage output terminal A by the switches S 1 , S 2 . The output is then not affected by wraparound-noise of the power source through the electric charge supply circuit 3.

Title: Controlling the propagation time of an optical delay line using radiation
Inventor: PESCOD CHRISTOPHER RALPH
IPC: G02B6/28
Filed: 1998-08-22
Abstract: A method of controlling the propagation time of light through an optical delay line (24), comprising exposing the inner core of the optical delay line (24) to a source of radiation (30). Exposure to radiation alters the refractive index of the inner core, and hence alters the propagation time of light travelling through it. The radiation may be focussed on the inner core, and it may also be moved with respect to the length of the inner core in order to distribute the time delay over the entire length of the optical delay line (24), and to prevent back reflections. The radiation may be ultra-violet radiation, and the photosensitivity of the optical delay line may be increased by exposing it to hydrogen before the exposure of the inner core to the radiation.

Title: System for recording/reproducing MPEG-2 broadcasting programs
Inventor: RYU CHOONG-II
IPC: H04N21/433
Filed: 1998-10-26
Abstract: An apparatus for reproducing and recording programs encoded according to MPEG-2 system standard into and from a recording media includes a recording apparatus for recording a transport stream of the same MPEG-2 broadcasting program and a demultiplexer for demultiplexing a transport stream according to a video PID and an audio PID. Video and audio bitstreams outputted from the demultiplexer are decoded by a MPEG decoder. The demultiplexer demuliplexes the transport stream read out from the recording apparatus according to a video PID and an audio PID, each of which is provided from a microcomputer. The microcomputer detects the video and audio PIDs from the transport packets of the transport stream based on whether the MPEG decoder detects a sequence header included in the transport packets or not. Therefore, the apparatus can decode the transport stream reproduced from the recording apparatus without the information about the video and audio PIDs of the transport packets which are recorded in the recording apparatus.
