Title: Voltage-controlled oscillator
Inventor: ZIRWAS WOLFGANG DIPL ING
IPC: H03B5/12
Filed: 1988-07-25
Abstract: It is known that voltage-controlled oscillators are temperature-compensated, as a rule, by means of one or more frequency-determining capacitors having specially selected negative temperature coefficients. The selection of the capacitors is very limited with respect to the number of temperature coefficients for certain capacitance values and this limited number is only obtainable in particular models. According to the invention, the collector terminal of a second transistor arranged in an amplifier stage without load is connected in parallel with respect to direct current with the collector terminal of the oscillator transistor, omitting capacitors having negative temperature coefficients. The second transistor can be an AF transistor, the first transistor has a basic cut-off frequency above 1 GHz with respect to the operating range of some 100 MHz to about 1 GHz. <IMAGE>

Title: Brake adjusting device for a motor vehicle provided with a hydraulic brake system and an automatic compensating system with air suspension
Inventor: RAPA ANTONIO
IPC: B60T8/18
Filed: 1988-12-12
Abstract: A brake adjusting device for a motor vehicle with a hydraulic brake system and an automatic compensating system with air springs has an operating device (22), which defines two chambers (28, 29), which are both divided by corresponding diaphragms (26, 27) into first and second spaces. The first spaces (28a, b) of the chambers communicate with corresponding air suspensions and the second spaces (29a, b) communicate with the surroundings by way of narrow passages (40, 41), the dimensions of which are calibrated so that in the event of a rupture of one of the diaphragms (26, 27) they limit the air loss to the surroundings. The air loss causes a change in the behaviour of the motor vehicle and this results in actuation of the compressor of the compensating system in order to compensate for the loss. <IMAGE>

Abstract: With certain picture formats, for example, presentation of 16:9 picture on a 4:3 screen, the cut off signals for the dark radiation current regulation inserted into the video signal can become visible in the black bands. The task is to avoid such signals becoming visible on the screen. The measuring process for the cut off regulation only happens briefly, for example, always only shortly after switching on the receiver. The result of the measurement (Uco) is stored in a memory (14) and read out from the memory (14) during most of the operating time.

Filed: 1989-11-09
Abstract: A system for connecting an umbrella's cover to the tip of an umbrella's cover rib (20 or 80) without sewing. The system includes a cap (50 or 86) comprised of an arm (51 or 81) that overlies the rib tip's flatted portion (21a or 83a), and a base (52 or 89) that interfits with the rib tip, the arm and base being formed integral one with the other. The cap's base cooperates with the rib tip for preventing at least one of longitudinal motion of the cap along the rib toward the rib's other end, and rotational movement of the cap about the through axis of the rib tip's bore. In use, either a pin is formed integral with the cap's arm (Fig 3) or a bore is formed through the cap's arm (Fig 7). When a pin is integral with the cap's arm, that pin connects the cap, the rib tip and the cover segment which overlies the tip, all in assembled relation. When a bore is defined in the cap's arm, a separate pin connects the cap, the rib tip and the cover segment which overlies the tip, all in assembled relation. <IMAGE>

Title: Boom flow control mechanism for pneumatic spreaders - has mechanism to interrupt flow of particulate material from preselected booms without clogging system
Inventor: TAKATA HARRY H
IPC: A01C15/04
Filed: 1990-02-15
Abstract: The improved system for pneumatic spreader systems is foer selective distribution of partic. material onto agriculturall fields from selected ones of a number of elongated delivery tubes or booms. The improved feature of the invention comprises mechanism to interrupt flow of partic. material from certain preselected booms without clogging the system. The system includes a stop for substantially completely blocking the flow cross-sectional area from a preselected one or number of delivery tubes, along with a line which normally functions as a feed line when the system is in normal operation, but as a recycling line when the delivery tube is in blocked or shut-off disposition. The arrangement provides a mechanism for converting a twin boom arrangement to a single-boom arrangement for accommodating unusual operation such as less-than-a-full boom width when undertaking the final run of a field application.

Title: Roller transporter for pallets - has common drive for rollers and with different speeds for different sections
Inventor: MOEGLE HANS-DIETER
IPC: B65G13/07
Filed: 1990-03-10
Abstract: The roller transporter has parallel sets of rollers over which the skids of the pallets are driven. The rollers are flanged to align the skids and are driven via a common belt drive alongside the tracks. A central motor (34) drives all the sections of the track. Different gear ratios etc. ensure that different track sections are driven at different speeds. One track section (20) is driven at a slower speed to restrain the pallets while other sections (20) are driven at a faster speed to separate the pallets. A movable stop (50) regulates the release of the pallets onto the fast section. ADVANTAGE - Improved transport control, cost saving common drive.

Title: DC current controller for inductive loads - uses by=pass semiconductor blocks with progressive switching to minimise component stress
Inventor: MARKS WALTER
IPC: H03K17/082
Filed: 1990-05-01
Abstract: Control of DC current through an inductive load is achieved by switching on and off rows of bypass semi-conductors, e.g. diodes via transistors, in parallel with the load current. A voltage or current measuring device signals the controller if a bypass semi-conductor switch-off point is approaching, which activates the required gate switching (for a MOSFET) or change of base current (for a bipolar transistor) until an initial value reached. When a second, lower value is approached, the controller switches in successive bypass blocks. Total switching times are arranged to be minimal and slow in progression. ADVANTAGE - Redn. of electrical stress to transistor and diode switching components.

Title: Yarn splicer - has aerodynamic splay and twist
Inventor: BANBA SUSUMU
IPC: B65H69/06
Filed: 1990-06-22
