Patent DE-3016710-A1 (DE)
Inventor: MAKSIN SVETISLAV DR ING
IPC: B29D30/56
Filed: 1980-04-30
Abstract: For retreading vehicle tyres, in a first process step, a roughened carcase is mounted on a rim with high shoulders. An adhesive and a readily adhering uncured-composition sheet are then applied onto the carcase in the width of the tread surface and a tread strip which is not prevulcanised to the optimum extent is laid thereon. The prevulcanisation is only carried out as far as the point at which the strip retains its shape, is not porous and can be readily roughened. A rubber casing is applied over the tread strip and the space between the rubber casing and tread strip is connected, via a valve, to a vacuum pump. After evacuation of this space, the final vulcanisation of the strip and its bonding to the carcase are initiated. For vulcanisation, the rubber casing is inflated to 2-3 atm and then heated to 120 DEG C. If the tread strip is only prevulcanised to 85% of the optimum, the vulcanisation time can be reduced by one hour in comparison with vulcanisation at 99 DEG C, increasing the capacity of a vulcanisation autoclave by 22.7%. <IMAGE>

Title: Differential PCM system for TV line reduction code - uses transform coding and spectral coefficient prediction to reduce TV transmitted line code
Inventor: MAY FRANZ DIPL ING
IPC: H04N19/00
Filed: 1980-08-01
Abstract: Bit rate reduction coding for the transmission of TV picture information over data transmission facilities at a maximum of 10 kbit/s. The picture , e.g. 100 000 spot images quantised into a 6 bit code representing 64 grey scale steps, is transmitted in ideally 1.5 seconds and at most 3 seconds. A transform code is used to convert the picture signal into a number of spectral coefficient values for transmission in a frame structure. DPCM (Differential PCM) transmission is used with a transmitted prediction for correlating picture samples. Each transmitted frame, w, of a picture, m, is derived by using actual picture spectral coefficient, y(u,v,w,m,), and previous picture (m-1) spectral corresp. coefficient, information so that prediction coefficient information is included. Consequently the difference value for each block, w, results. Further processing derives magnitude classifications, c(w,m), for each sample in the overall picture. The signal from the TV camera (1) is A/D converted (2) and stored (3) in a 16 x 16 format. Transform coding (4) and coefficient classification, DPCM prediction and quantisation (7,8,9,10,11) then precede modem (12) transmission.

Title: Sensitivity control of measurement bridge indicator - has amplifier whose gain varies inversely with measurement current
Inventor: JAUNICH GERD
IPC: G01R31/08
Filed: 1980-08-30
Abstract: The arrangement for adjusting the sensitivity of indicators in measurement bridge circuits is esp. applicable to fault detection in cables where the indicator is connected into the bridge diagonal via an amplifier. It is a development of similar arrangements which results in approximately constant relative sensitivity over a wide current range. The amplifier (2) is controlled via a highly insulated transducer (5) according to the measurement current (Im) value so that the amplifier gain (V) is inversely proportional to the measurement current and the indicator (1) sensitivity is affected in proportion to the gain. The transducer (5) is isolated by means of an optoelectrical, electromagnetic or electromechanical transistor-receiver coupling. The sensitivity is automatically increased for reducing current and vice-versa.

Title: Agricultural vehicle chassis frame - narrows in centre to allow front wheels to turn further to provide smaller turning circle while using four equal sized wheels
Inventor: GOEBEL HANS DIPL ING
IPC: B62D21/18
Filed: 1980-12-06
Abstract: The agricultural vehicle consists of an engine (1) connected by a pair of lateral girders (2) to a gear box which is driven by a drive shaft (6). The lateral girders (2) are bent inwards so that when the front wheels (5) are turned the extra angle allowed enables a tighter turning circle. The wheels (5,12) are held below the frame members (15) so that the ground clearance is about 60 to 80 per cent of the wheel depth, while the wheel dia. is about 60 to 40 per cent of the track width. This method provides a vehicle which has a narrow track width yet small turning circle required for use in fields.

Title: Device for improving the mixture formation in spark ignition engines
Inventor: BARKA LAJOS
IPC: F02M29/04
Filed: 1981-03-26
Abstract: The invention relates to a device for improving the mixture formation in spark ignition engines, in which a pressure reducer, principally a venturi tube is fitted in the intake pipe. The essence of the invention lies in the fact that downstream of the venturi tube of the carburettor an additional restriction is formed which has a curved generatrix. It is proposed that the smallest diameter of the restriction be approximately 90% of the intake pipe diameter, the length of the restriction, however, 50%, advantageously 15 - 25% of the intake pipe diameter. By using the proposed device, the efficiency of the atomisation can be improved and the combustion rendered more complete, which is associated with an improvement of the mixture formation. In such engines, a fuel saving of 5 - 8% can be obtained by all these measures.

Title: Process and apparatus for producing a packaging band for cylindrical or conical articles
Inventor: BECKER THOMAS DIPL ING
IPC: B65B9/02
Filed: 1981-04-16
Abstract: The invention relates to a process for producing a packaging strip for cylindrical and/or conical articles from two parallel interconnected bands surrounding the articles. In this process, the articles to be packaged, conveyed individually at a distance from one another, are pushed in between two bands running in the conveying direction and, by being taken up, are fixed between these. The packaging band thus obtained is subsequently cut to length. The invention relates, furthermore, to an apparatus for producing a packaging band, especially of the abovementioned type, with at least two conveying devices (5, 6, 7, 8), of which the circumferential surfaces form, in the region of introduction (27) of bands (20, 21), a gap which narrows until there is mutual contact between the circumferential surfaces and in front of which a pushing-in element (4) is oriented in the direction of the gap, as seen in the conveying direction. <IMAGE>

Title: Process and device for the continuous gluing of wood chips and other lignocellulose-containing particles
Inventor: WINKLER HERMANN
IPC: B27N1/02
Filed: 1981-05-05
Abstract: In the continuous gluing of wood chips and other lignocellulose-containing particles with binder, the object is to distribute the binder as homogeneously as possible on the surface of the wood chips. For this purpose, horizontal mixing tanks are known which possess a driven mixing shaft in their interior and are equipped with tools which in part also feed the binder. To achieve a more homogeneous, that is to say more uniform, distribution of the binder on the surface of the wood chips, the invention provides first of all to increase the surface area of the binder, that is to say to form a binder/air mixture, before the binder encounters the relatively large surface of the wood chips or comes into contact therewith. For this purpose the binder is injected at high pressure into a zone free of chip material and at a distance from the ring of chips, and atomised to form a mist for which purpose it is necessary to provide a clear path so that the binder/air mixture can form and expand. The pipes (21 and 23) for feeding the binder may be provided either in the interior on a driveable mixing shaft (9) or else stationary in the region of the tank wall. It is essential that the nozzles (22) of the pipes (21 and 23) terminate within the space surrounded by the ring of chips and at a distance from the ring of chips (15). <IMAGE>

In this case, the swivel part (8) can be swivelled counter to a spring force on a swivel path between a basic position and an end position. Furthermore, the device has a detecting device which can be actuated by the swivel part (8). In order to provide a multiple sheet control device of this type which, with a simple construction, can quickly be adjusted into its optimum operating position, the detecting device can be actuated during the swivelling of the swivel part (8) from its basic position before it reaches the end position. <IMAGE>

Title: Use of a device for exchanging heat between a gas stream and lumpy material
Inventor: BALSTER HUGO DIPL PHYS DR
IPC: C10J3/00
Filed: 1981-08-06
Abstract: The invention relates to the use of a low-temperature carbonization unit and gasification unit for the exchange of heat. In this case, a gas in any desired form is fed from below to the unit, according to P 2,906,810, and extracted at the top of the unit. The heat exchange takes place on a layer of material, which slides in a lumpy form from the top down over grates set in an inclined position. The invention eliminates the expensive operation of rotary kilns, shaft furnaces or fluidized-bed furnaces. The possibility of simple adjustment of the thickness of the material layer and of the gas velocity permits optimum heat transfer, in a way which is not possible in any of the processes indicated above. The application of the invention is advisable especially in the non-metallic minerals industry and in coal utilisation for drying, cooling and heating, it being possible to operate with material temperatures of up to more than 1000 DEG C.
