Patent DE-3123684-A1 (DE)
Title: Shock absorber for the feed table of a machine tool
Inventor: URABE HIROKUNI
IPC: F16H25/20
Filed: 1981-06-15
Abstract: A shock absorber for a table or a tool holder in a machine tool, such as, for example, a grinding machine, a lathe, a milling machine, a rolling machine, a planer or a drilling machine, has catch steps (15, 16) on a feed nut (7), running on a feed spindle (2) of a sliding table (8) or a tool holder, and on a connecting part (12) under the sliding table (8) or the tool holder or on a bush (13) fastened to the connecting part (12) and combined with the latter. Arranged between the feed nut (7) and the connecting part (12) or the bush (13) is a sliding collar (19) which has a catch section (17, 18) which comes into engagement with the corresponding catch steps. One end of the sliding collar (19) projects beyond the outer end of the feed nut (7) lying on the same side in order to be able to mount a spring-locating part (20). A hollow or empty chamber (S1) is thereby formed between the sliding collar and the feed nut on the same side. The other end of the sliding collar is set back behind the outer end of the connecting part (12) or the bush (13) on the same side, and a further spring-locating part (23) can be mounted on the connecting part (12) or the bush (13). A hollow section (S2) is thereby formed on this side of the sliding collar (19). The two hollow sections (S1 and S2) are provided with an elastic element (e.g. a spring 22 or 25). These elastic elements are compressed or expanded so that shocks produced by unusual collisions at the machine are dampened. <IMAGE>
Patent DE-3127106-A1 (DE)
Title: Device for radiation shielding and propagating gas
Inventor: MILLER ROBERT CHARLES
IPC: B64D33/04
Filed: 1981-07-09
Abstract: The device serves to shield a hot surface in order to prevent detection of the surface by an infrared radiation detector owing to the infrared radiation emanating through an opening on the hot surface. The device has a gas-conducting element which absorbs hot gases and has an outside and an inside, and in addition an inlet for absorbing hot gases from the said opening and an outlet for discharging gases. The gas-conducting element is constructed such that the inlet of the element cannot be directly seen from the outlet of the element. The device has, furthermore, a facility with which cooling air can be guided over the outside of the gas-conducting element. Subsequently, the cooling air can be mixed with the hot gases inside the said element. As a result, the gas-conducting element is cooled, so that for its part the element cannot be detected by an instrument for detecting infrared radiation, and moreover cooling of the gases emanating from the outlet of the gas-conducting element is performed by mixing of the hot gases with the cooling air. <IMAGE>

Title: Liquid-metal push-button switch
Inventor: TIRVA ADOMAS ADOMOVIC
IPC: H01H13/12
Filed: 1981-08-13
Abstract: The liquid-metal push-button switch contains a permanent magnet ring (7) which is arranged such that it moves to and fro (in a reciprocating manner) in a housing (1). A layer (9) extends over the entire surface of the permanent magnet ring (7) and consists of two metals, one of which is soluble in mercury. A liquid-metal film (11) is deposited onto this layer (9), over its entire free length. Current-conducting contacts (3) are passed through the base (2) of the housing (1). Metal layers (10) consisting of two metals are deposited on that end surface of the contacts (3) which is located in the interior of the housing (1). One of these two metals is soluble in mercury. Liquid-metal films (12) extend over the entire length of these layers (10). The liquid-metal film (11) makes contact with the liquid-metal films (12) when the permanent magnet ring (7) is displaced, and is used as an element (8) which closes the current-conducting contacts (3). <IMAGE>

Title: Frequency control circuit for electrical power stations and power distribution networks
Inventor: GRIMM GERMAN DIPL ING
IPC: H02P9/04
Filed: 1981-10-09
Abstract: Control of power station blocks with less than all the generators running, which is disadvantageous economically and technically, and increased wear in the control devices are avoided using a frequency control circuit, in that a dynamic threshold value of the frequency deviations which initiate control action is created by means of a correction circuit, which dynamic threshold value permits larger deviation values at the start of a frequency deviation and approaches a static threshold value asymptotically thereafter, within a specific time period. In consequence, it can be achieved that 95% of all frequency deviation cases are left to the self-controlling characteristics of the composite networks and control actions are required in only 5% of frequency deviation cases. <IMAGE>

Title: Method for lining pipes
Inventor: KINUMOTO NAMIO
IPC: B05C7/08
Filed: 1982-02-24
Abstract: Method for lining a large pipe and small pipes which branch from said pipe using a sealing compound, the pipes being lined in the mutually connected state and the large pipe or the small pipes being first lined. That part of the sealing compound which is pressed into the small pipes when the large pipe is first lined using a running element, is pressed back again into the large pipe and, without being discharged from the system, is subsequently applied to the lining layer of the large pipe, specifically as a top coating using a running element which has a slightly smaller diameter than the previously used running body. If one of the pipes has a part which is bent over to a large degree, a running body is used which has two running elements which are each symmetrically shaped, are congruent with respect to one another and connected to one another by means of a flexible linear element.

Title: Process for heating rooms by means of surface radiation, produced by warm air which circulates in closed circuits in air ducts, which are to be specially dimensioned, in the floor
Inventor: MACHOWETZ WOLFGANG DIETRICH DI
IPC: F24D5/10
Filed: 1982-10-20
Abstract: For heating the floor which borders the room air, warm air is guided through the floor of each room to be heated through air ducts designed specifically for each room from a supply air distribution chamber, formed by the system itself, which is for instance arranged in the hall of a storey. The end of the warm air duct of each room to be heated separately opens in a passage opening through the ceiling of this storey. On the underside of this ceiling region, there are installed below the passage openings, room-specifically dimensioned fans which suck the cooled circulating air out of the respective room ducts and press it into the return air collecting chamber which is created between the ceiling underside and a ceiling as it were suspended below it. The only path which the return air under pressure can follow leads via an air heater, which corresponds to the heat requirement, through a ceiling passage opening and back into the supply air distribution chamber. Optimum automatic control is thus possible at the same time via the warm air temperature and the individual room temperature control and the system is as a whole closed.

Title: Process for transferring a suspension, which is to be hydrogenated, of fresh coal and pasting oil
Inventor: WUERFEL HELMUT DIPL ING DR
IPC: C10G1/06
Filed: 1982-11-05
Abstract: In the process for transferring a suspension, which is to be hydrogenated, of coal and pasting oil to the coal hydrogenation pressure, an auxiliary fluid is used for pressure transmission. For this purpose, the suspension is transferred from at least two transfer vessels, one vessel being filled with the suspension while the other is emptied by introducing the highly pressurised auxiliary fluid. The pressure-transmitting auxiliary fluid is pasting oil, that part of the pasting oil which mixes with coal particles in the course of transferring the coal suspension being continuously taken off and being replaced by fresh pasting oil. The contaminated part of the pasting oil is used directly for preparing the coal suspension.

Abstract: For the separate stapling of sets of copies coming continuously from a copier, a delivery surface (104) is provided which is inclined through a certain angle ( alpha ) in relation to the horizontal and on whose lower end the stapling device is arranged. During the stapling process, the set of copies (143) is held by means of a movable stop flap (107) which after the stapling process releases the stapled set of copies for further transport by the force of gravity. The rapid opening and slow closing of the stop flap (107) which is necessary for unimpeded transport by gravity is simply initiated by means of a crank guide (138-140) which is driven for one rotation each time by a drive motor (135) with a constant direction and speed of rotation. <IMAGE>
