Title: Change-speed transmission with a bevel and spur gear mechanism
Inventor: NOVACEK JOSEF DIPL ING
IPC: F16H57/038
Filed: 1982-02-12
Abstract: The invention relates to a change-speed transmission with a bevel and spur gear mechanism for driving the belt conveyor in above-ground coal mining. The invention relates to the constructional solution for the two-part case of the bevel and spur gear mechanism and the manner of mounting the rolling bearings of the driving bevel gear in the transmission case. It is the object of the invention to make a considerable improvement in the lubrication of the three bearings mentioned and to simplify the structure and manufacture of the transmission case. The essence of the invention of the bevel and spur gear mechanism with shafts in the horizontal position which are supported in a two-part case of the transmission, which is split in the axis of the shafts and consists of a lower part and a cover of the transmission case, lies in the constructional solution for the case of the transmission, in which the flanges of the lower part of the transmission for supporting the rolling bearings of the driving bevel gear are formed in the interior of the lower part and of the cover of the transmission casing. In this arrangement, the driving bevel gear is supported with its rolling bearings in the said flanges of the lower part of the transmission case such that, on one side, it is supported next to the hub in the flange, radially in a radial rolling bearing and axially in two axial barrel-type rolling bearings and, on its other side, is supported at the entry journal in the inner flange, radially in the radial rolling bearing.

Title: Optical arrangement for image displacement
Inventor: GROSSER JOHANNES DIPL-PHYS
IPC: G02B26/08
Filed: 1982-02-15
Abstract: The invention relates to an optical arrangement for image displacement by means of reflecting surfaces. Such arrangements can be constructed as separate units and be applied, e.g. as measuring tubes in different optical instruments, such as microscopes, telescopes, adjusting devices, interference devices and photogrammetric instruments. The aim of the invention is an arrangement for image displacement, in which the image displacement is produced by means of displaceable mirrors and it is possible to have a large range of possible angles between the directions of the incident and outgoing beams. The ratio of mirror displacement and image displacement is to be known, and the aim is to be able to realise systems having different scale factors. The arrangement consists of an input mirror and an output mirror, parallel to the latter, whose reflecting surfaces are located opposite one another and between which at least one reflecting surface is located in the beam path. An image displacement is produced by displacing the input and output mirrors in an essentially identical direction. <IMAGE>

Title: Method and device for measuring tube vibrations
Inventor: KIEFER RUDOLF DIPL PHYS
IPC: F41G3/32
Filed: 1983-03-09
Abstract: In order to determine the tube vibrations of a weapon tube 36 moving to and fro in the direction of the arrow 37, radio-frequency waves are transmitted from a radio-frequency transmitter 32 via an antenna 35 onto the outer circumferential surface of the weapon tube 36. A portion of the radio-frequency energy reflected from the weapon tube 36 is received once again by the antenna 35 and fed via a circulator 30 to a mixer 33 which establishes the phase shift caused by the tube vibrations by comparison with the radio-frequency energy generated by the radio-frequency transmitter 32 and supplied via a coupler 31. The respective position of the vibrating weapon tube can be determined in a simple way from this phase shift and can be displayed or stored for further evaluation processes. <IMAGE>

Title: Method of processing an alumosilicate raw material to give alumina, soda products and cement
Inventor: KALUSSKIJ NIKOLAJ A
IPC: C04B7/32
Filed: 1983-05-26
Abstract: The method comprises the processing of a blend of an alumosilicate raw material, soda and calcium carbonate, sintering of the blend obtained, leaching of the sintered material, separation of an aluminate solution from the belite sludge, desilification of the aluminate solution in two stages, the solution being desilified in the second stage by treatment with a pulp which contains the oxides CaO, Al2O3, SiO2, Fe2O3 and Na2O and in which the weight ratio between the oxidates for CaO: (SiO2 + Fe2O3) is 1000 - 5000 to 1 and for Na2O: Al2O3 is 0.25 - 0.60 to 1, the CaO being active and the Na2O being the carbonate. The pulp is taken off in a quantity which is sufficient to ensure a content of active CaO in the solution in a range from 5 to 10 g/l. The calcium hydroalumosilicate which has been separated from the desilified solution is used for producing two grades of cement, namely: 1) a cement which is suitable for making foundry cores and moulds and 2) a cement of high alumina content. To make the cement for producing foundry cores and moulds, a calcium hydroalumosilicate is subjected to heat treatment at a temperature from 250 to 600 DEG  and to fine grinding. To make the cement of high alumina content, a calcium hydroalumosilicate is mixed with aluminium hydroxide in a weight ratio of 0.25 to 0.50 : 1, calculated as CaO:Al2O3, which ...

Patent DE-3400478-A1 (DE)
Title: Chassis
Inventor: GEISSELER HELMUT
IPC: B60G11/04
Filed: 1984-01-09
Abstract: The invention relates to a chassis with axle support, especially a refuse vehicle chassis, with a spring arrangement having at least one parabolic leaf spring, which arrangement is supported on the chassis frame in a fixed bearing and in a loose bearing close to one of its ends and to which the axle is fixed between the two bearings. In known chassis an asymmetrical trapezium leaf spring was used to obtain as short an overhang as possible. Apart from the high weight of the unsprung mass of the trapezium leaf spring, the overhang could not be sufficiently shortened. An air spring with parabolic core had therefore to be used which is extremely expensive. According to the invention an exceptionally short overhang of the chassis beyond the axle fixing is achieved in that the parabolic leaf spring in relation to the axle fixing is asymmetrically formed with a longer and a shorter part and that the parabolic leaf spring is supported by its shorter part in the bearing adjacent to the chassis frame end, up to which the overhang of the chassis frame is shortened.
