Title: Ratchet screwing tool
Inventor: ROGG KARL-HEINZ ING GRAD
IPC: B25B21/00
Filed: 1982-08-13
Abstract: The invention relates to a pneumatically operated ratchet screwing tool which, by means of an additional device, is constructed so that it is also suitable for screwing on self-securing nuts which are screwed onto co-rotating shafts or the like. The additional device forms a counterholding means which prevents rotation of the shaft or the like while the self-securing nut is being screwed on.

Title: N,N'-Diphenyl-p-phenylenediamines, their preparation and their use as stabilisers for organic materials
Inventor: MUELLER ROLF DIPL ING
IPC: C09K15/18
Filed: 1982-08-18
Abstract: N,N'-Diphenyl-p-phenylenediamines of the formula <IMAGE> in which R1 and R2 can in each case be identical or different and represent hydrogen, 2-methyl-2-butyl, 2,4,4-trimethyl-2-pentyl, 4,6-dimenthyl-2-heptyl, 4,6,8-trimethyl-2-nonyl, cyclohexyl, 1-phenyl-1-ethyl or 2-phenyl-2-propyl, but cannot simultaneously be hydrogen, and R3 and R4 can in each case be identical or different and are hydrogen, methyl, ethyl or methoxy. These compounds are stabilisers for organic materials which protect the latter in particular against aging caused by high temperatures, atmospheric oxygen, ozone, light, exposure to microbes and dynamic stress, if appropriate during the simultaneous catalytic action of heavy metals, and which are therefore valuable age protectors for such materials.

Title: Air filter for an internal combustion engine
Inventor: STAROBINSKY RUDOLF NATANOVIC
IPC: F02B3/06
Filed: 1982-10-12
Abstract: An air filter for an internal combustion engine is proposed which contains a housing 1 which is designed in the form of a circular cylinder with an inlet slot on which an air intake pipe 3 is arranged whilst an outlet slot 5 is located in the base of the housing 1. Inside the latter lies a filter element 6 on the same axis as the housing 1. According to the invention the centres of the inlet and the outlet slot 2 and 5 lie in planes running perpendicular to one another which run through the axis of the housing 1, whilst the centre of the outlet slot 5 is offset towards the axis of the housing 1 by a value of (0.58 to 0.68)R, where R is the radius of the base area of the cylinder of the housing 1. The invention may be used in inlet systems of all combustion engines on means of transport with vehicle, ship and diesel locomotive engines and on fixed combustion engines, for example on generators and compressors in cases where the noise emitted has to be kept to low levels. <IMAGE>

Title: Push button for making and/or breaking electrical circuits
Inventor: GUEROTTO MARCO
IPC: H01H13/28
Filed: 1983-04-14
Abstract: A push button is described for making and breaking circuits, which has both a long life and preferential electrical properties, as well as permitting operation with an unambiguous amount of force being exerted. To this end, a push button (11) is surrounded by a tension spring (12) which, for its part, rests on a shoulder (14) and is closed to form a circle. In order to operate the push button, the tension spring (12) is first expanded and, hereupon, is pushed over the shoulder (14) onto an expanded part (17) of the shaft (13). In this case, a contact laminate (16) is pushed onto the conductor tracks (18, 19), which are to be connected, of a conductor arrangement (20) which is inserted in a bedding (23). In the absence of the pressure on the push button (11), the tension spring (12) contracts, returning onto the cylindrical shaft (13). The push button is advantageously enclosed by a waterproof sheath (24). <IMAGE>

Title: Process for the preparation of silicon dioxide which can be used as a filler of low  alpha -activity for plastics
Inventor: AULICH HUBERT DR
IPC: C09C1/30
Filed: 1983-07-01
Abstract: The invention relates to a process for the preparation of SiO2 which can be used as a filler of low  alpha -activity for plastic. The SiO2 is obtained by converting SiO2-containing mineral materials containing aluminium oxide, boron oxide and carbonates and/or oxides of alkali metals or alkali earth metals into the glass phase by melting, producing glass elements of large surface area from the glass melt, and producing a glass matrix which is free from impurities, in particular from the elements thorium and uranium which are responsible for  alpha -emissions, from these glass elements by leaching in hot mineral acid. A product is obtained which has an alpha -emission rate of < 0.01  alpha /cm<2>h and can be employed as a filler for plastic claddings in semiconductor technology, including for K stores.

Patent DE-3334038-A1 (DE)
Title: Glow plug
Inventor: WIDEMANN FRIEDRICH
IPC: F23Q7/00
Filed: 1983-09-21
Abstract: A glow plug with a glow wire in the form of a glow coil is described, and is especially intended for heating appliances with evaporating burners. The glow coil is arranged lying freely on the exterior of a ceramic insulating body arranged in a plug housing. Several glow coils are arranged in an even distribution in the peripheral direction of the ceramic insulating body. Each glow coil runs in a straight line in the direction of the longitudinal axis of the glow plug, and the glow coils run parallel to each other. With a supply voltage of 24 V, the glow coils are electrically connected in series, and with lower supply voltages, such as at 12 V, they are connected in parallel. In glow plugs without a middle electrode, an even number of glow coils, and in a glow plug with a middle electrode, an odd number, of glow coils is provided. One or more of the glow coils can here act as control coils, by the use of a glow wire with a positive or negative resistance coefficient. Such a glow plug can thus also be operated with 24 V vehicle supply systems such as are usual today, ensuring a favourable thermal economy without too high a current drain.

Title: Device for wrapping tape round a parallelepipedal article
Inventor: LANG GEORG
IPC: B65B27/08
Filed: 1983-02-05
Abstract: In a device (1) for wrapping tape round a parallelepipedal article (2), two tape guiding frames (3, 3') are provided, the planes of the frames being perpendicular to a conveying plane (5). Continuous belt guiding channels are provided in the frame planes, it being possible to guide a wrapping tape in each one of the channels around the inside of the frame opening. The wrapping tape is placed round the article (2), tensioned, sealed and cut off using an additional automatic device. In order to wrap tape round the article (2) crosswise, it has hitherto been necessary to turn the article (2) through 90 DEG  between the two tape wrapping actions carried out perpendicular to one another. In the invention, this turning is avoided by having one frame plane in the conveying direction and the other transverse to it. The frame planes can intersect one another in particular. A high processing speed is achieved in this way with fewer malfunctions (see illustration). <IMAGE>
