Abstract: A brake booster in a housing, having a servo piston slidably supported in the housing and having a piston rod protruding into the housing for transmitting a brake force. A chamber is provided in the servo piston for receiving brake fluid drawn after the opening of a valve from a reservoir or supply container and pumped via a pump or the like. The chamber also communicates via a further valve or the like with a return line to the supply container. To improve the closing behavior of the valve, the first valve for the admission of the brake fluid is formed in the chamber, embodied as a servo chamber, by a valve bushing, or its annular collar, and a valve seat in a blind bore recess in the servo piston. On the other side, the valve bushing, with a bottom, engages the inside of a bell-shaped valve seat, which together with the piston rod, or a slide connected to the piston rod, forms the valve for returning the brake fluid.

Abstract: Both the analog and the video component of a television signal are converted to digital form, the audio component being converted at a much lower sample rate with a word length which is an integral multiple of the video word length. The digital audio component is then compressed by use of a temporary memory and read-out therefrom at a rate that is half of the sample rate of the digtal video component, after which the word length is halved and the word rate doubled in a shift register circuit. In that form the audio component is inserted in horizontal blanking intervals of the video component in a compatible form by a multiplexer, the output of which is read into a single picture field or full picture memory under control of an address generator clocked in synchronism with the incoming video component. The buffer memory is read-out at a rate controlled by a reference signal such as is used for synchronism in a television studio.

Abstract: For transmission of serial digitally coded signals over a path having a high-pass frequency characteristic synchronizing signals are transmitted in synchronizing word pairs at the beginning of each data block in which the synchronizing words are either identical or else both have the same number of bits of each of the two binary logic levels, for reduction of d.c. and low-frequency components while permitting the choice of a synchronizing signal word which occurs at most rarely in a television video signal, for example.

Abstract: A bushing made of elastic plastic, spherically receives a ball pivot of an adjusting screw and is fixed in a socket which protrudes from a back side of a reflector. Two spring clips of the bushing grip two catches of the socket from behind, and two rails of the hollow journal cooperate with two slot links of the frame. This ball-and-socket mounting, which is coaxial with respect to the adjusting screw can be assembled by robots and does not cause any bending moments that unfavorably affect the reflector mounting.

Abstract: The invention is directed to a method for triggering switching functions in which the latter are triggered when the position signal emitted by a position transmitter exceeds or falls below a predeterminable signal level, the position signal being corrected and scaled in a signal-processing arrangement. A precise, long-term stable correspondence of the predeterminable signal level to a definite position of the position transmitter is assured in that the end values of the position signal corresponding to the two end stops are ascertained in a learning algorithm after each time the position transmitter is put into operation. The method is particularly suitable for triggering switching functions in a motor vehicle which has a position transmitter as a desired-value transmitter of an engine performance control or regulating system, the position transmitter being mechanically connected to the accelerator pedal of the vehicle.

Abstract: Self propelled pallet vehicles (12a) are guided along a track network (10) by downwardly projecting guide pins (350, 352) carried by each pallet vehicle (12) which engage slots (354, 358) in the track network and steer the pallet vehicle (12) along the track network (10). The track network has main (20) and branch (22) track sections, and selective delivery of the vehicles to various destinations along the track network (10) is achieved by controlling the position of the guide pins (350, 352) between alternate rotated raised and lowered positions. In the lowered position the guide pins (350, 352) interact with the track network (10) to guide the pallet vehicle (12) into a branch section (20) of the track. In the raised position, the guide pins (350, 352) cause continued movement of the vehicle (12) along the main track section (22) and past a junction (38). The guide pin position may be controlled by a photoemitter (364) at the junction (38), or by various other alternatives.

Abstract: A fluid power control valve apparatus is disclosed and is characterized by combining desirable features of both a spool type valve element and a poppet type valve element. A spool element is provided with one end adapted to be seated in a poppet valve seat provided in the bore in which the spool is slideably mounted. The poppet seat is located in the bore between two flow ports. The poppet end of the spool engages and becomes fully seated only after the spool has passed a bore position closing one of the ports to operative flow and operates to seal the bore from the conventional leakage flow associated with spool elements. Also disclosed is a method of manufacturing such an apparatus in a two piece assembly to greatly simplify manufacture of a precise poppet seat within the spool bore.

The preferred method of administration is by oral dosages of about 1/2 to 3 grams/kilogram bodyweight per day.

Abstract: A tea making machine wherein the bottom wall of an upper vessel can be used to seal the open top of a lower vessel which contains a supply of water. The upper vessel contains a supply of tea leaves and its bottom wall has an upright tubular portion for a riser with an open upper end in the upper vessel and an open lower end in the lower vessel. The riser is adjustable so that its lower end can be moved to any one of a number of different levels above the bottom of the lower vessel. When the supply of water in the lower vessel is heated, the pressure in the lower vessel rises and boiling water is compelled to flow up the riser and into the upper vessel where it contacts the tea leaves. When the level of the supply of water in the lower vessel descends below the lower end of the riser, such water must be evaporated in order to rise into the upper vessel. The interval which elapses for evaporation determines the steeping time in the upper vessel.

Abstract: Device for storing small articles and conveying them in an orientated manner, includes a storage container (10), a slope conveyor (12), and an orientation conveyor (20) which is arranged parallel to the slope conveyor and is provided with a defined segment (68) for returning excessive small articles or those which are not orientated to the feed area (32) of the slope conveyor (12). The slope conveyor is provided with the actual conveying segment (50), a deflecting segment (52) for receiving small articles which are forced out of the conveying segment (50) laterally, the small articles arriving back in the feed area (32) of the slope conveyor (12) on the deflecting segment (52). A pile-up of small articles arrives in the output area (40) of the slope conveyor (12) and a localized circulation is formed in this location which prevents the small articles from entering the orientation segment (64).

Abstract: In known devices, the fuel injection valves, disposed in individual receiving bores, are retained individually with clamping shoes, and electrical contact is provided by individual electric plugs. The novel device is intended to assure that all the fuel injection valves are retained and provided with electrical contact simultaneously. The fuel injection valves inserted into receiving bores of a basic body are retained in common in the receiving bores by means of a contact-making outlet strip, slipped onto the basic body, and are electrically connected in common by means of electrically conductive contact elements. The entire compact device can be fastened as a unit to the engine and electrically connected, via a connection plug to an electronic control unit for trigging the fuel injection valves. The device makes adaptation to various engine types possible.

Abstract: An automatic reorder and alarm system for use with residential fuel-oil tanks which sends reorder and alarm data to a central station over the direct-dial telephone network when the fuel-oil level in the tank falls below a predetermined value or when an alarm situation, such as low temperature, occurs at the tank location. An inexpensive sensor/sending unit located at each customer tank includes a simple sensor which mounts on either the tank or an existing fuel-oil level gauge, a microcontroller circuit and a modem circuit. The microcontroller circuit uses a simple low-stability oscillator as a reference for internal operations and for modem transmission frequencies. Because the oscillator frequency cannot be precisely determined due to component tolerances and has a substantial amount of drift, a special data transmission format is used for data transmission over the telephone lines between the microcontroller and the central station.
