Title: Process for the preparation of 3-mercaptopropionic ester
Inventor: ORITA RYOZO
IPC: C07C67/00
Filed: 1986-04-24
Abstract: The invention relates to a process for the preparation of 3-mercaptopropionic ester from H2S and acrylic ester in the presence of 3,3'-dithiodipropionic ester, in which an insoluble anion exchanger resin is used as catalyst in a batch-like or continuous procedure and the ester is synthesised in a technologically relevant way, the reaction temperature being approximately 0 to 60 DEG C and the reaction pressure being 0 to 13.5 kg/cm<2> (G) (G: manometric pressure), the yield of 3-mercaptopropionic ester being 91 to 96% based on the acrylic ester and its purity being above 99%, measured by GLC (gas liquid chromatography). In this invention, the 3-mercaptopropionic ester is synthesised in high yield and high purity and is suitable for conditions or uses in industry. The advantages of this invention are that 3-3'-dithiodipropionic ester, which is present during the reaction, is not utilised at all and can be used repeatedly and, since the anion exchanger resin is used as catalyst, it can be removed from the reaction system by a simple filtration.

Title: Loading ramp
Inventor: PFEIFFER GERD
IPC: B60P1/44
Filed: 1986-09-10
Abstract: The invention relates to a loading ramp for heavy goods vehicles or the like, having a platform which is supported by a lifting mechanism and can be pivoted relative to the lifting mechanism about a horizontal axis from a loading ramp position into a tailgate position by means of at least one hydraulic cylinder (closing cylinder). According to the invention, it has a bearing and/or pivoting device for the platform with a blocking device which, during or after pivoting-up without using the closing cylinder and in the case of a drop in pressure thus caused in one or the cylinder space of the closing cylinder system which can be filled to carry out the platform closing operation, automatically prevents the platform from pivoting down unintentionally, at least by more than 10 cm, and to which an unblocking device is assigned. The unblocking takes place either automatically, in this case after the closing cylinder system has been filled with the required pressure ("intended pressure"), or by remote control at the manual switch cabinet. In both cases, it is ensured that the platform cannot drop down onto the operator. <IMAGE>

Patent DE-3723493-A1 (DE)
Title: Device for load-dependent control of the brake pressure in multi-axle vehicles
Inventor: STUERNER JOHANN DIPL ING
IPC: B60T8/18
Filed: 1987-07-16
Abstract: In a known control device for load-dependent control of the brake pressure in multi-axle vehicles with a leaf-sprung live axle and a raisable trailing axle, a difference in control travel between operation with trailing axle raised and lowered is obtained for the same spring travel (axle load) and consequently less than ideal braking, at least in one of the operating modes. The object of the invention is to create a control device in which, with the aid of simple means, the same braking conditions for the same axle load are possible in all operating modes, irrespective of whether the trailing axle is raised or lowered. According to the invention, the distance between vehicle frame (27) and live axle, caused by the compression and rebound of the live axle (12) under different axle loads and varying as a function of the load, is used as control travel for a brake pressure control device (19) fixed to the frame. <IMAGE>
Patent DE-3727195-A1 (DE)
Title: Additional gas feed device on an internal combustion engine
Inventor: MANGOLD ANTON
IPC: F02M26/36
Filed: 1987-08-14
Abstract: A device is described by means of which the pollutant emission content of the exhaust gas from an internal combustion engine with applied ignition is reduced in the cold starting phase. In this operating condition, that fuel which collects on the carburettor wall is caught and mixed with additional gas, especially exhaust gas recirculated from the exhaust, atomised and fed to the intake pipe. By means of a collector, a predetermined quantity of fuel is retained in order to bypass the starting sequence until introduction of the collected fuel. The atomisation occurs at the outlets of a distributor which is arranged concentrically with the annular collecting channel in an intermediate flange between the carburettor outlet and the intake pipe. Water vapour or water condensate is preferably extracted by means of a heat exchanger in the exhaust system and mixed with the collected fuel.

Patent DE-3734363-A1 (DE)
Title: Device for adjusting a motor-vehicle seat
Inventor: SCHNEIDER FRITZ ING GRAD
IPC: B60N2/06
Filed: 1987-10-10
Abstract: The intention is for the adjusting device either to be equipped with a driving motor or with a handwheel and, whilst being of a design which saves space and is inexpensive to produce, for it to lock in a very efficient manner any movement of a driving wheel, which meshes with an operating element, on itself as a result of the motor-vehicle seat being loaded. To this end, it is, amongst other things, provided that a coupling disc which is on the driving side and has dogs protruding around the circumference and parallel to the axis constantly engages with in each case one tooth-shaped recess in a coupling disc on the output side, each dog being flanked by two clamping elements of which that clamping element which lies in front of the dog when the driving-side coupling disc is rotated, is capable of being pressed by the dog out of a tapering clamping region in the recess and against a tooth profile of the coupling disc on the output side. The adjusting device serves primarily for the longitudinal displacement of the entire motor-vehicle seat, but is also suitable for the separate adjustment of individual sections.

Title: Spectacle frame for corrective spectacles
Inventor: WEBER KARL
IPC: G02C9/02
Filed: 1987-10-13
Abstract: A spectacle frame for corrective spectacles has removable coloured glare shields such as are required if the corrective spectacles are also to be used as sunglasses or in certain cases of partial sightedness. It is proposed to arrange a holding element, in conjunction with supporting elements arranged in the region of the lower spectacle frame, in the upper region of the spectacle frame between the two frame parts of the spectacle frame which in each case bound a viewing field, above the bridge. The holding element can be swivelled counter to a spring load and is arranged in such a manner that, if the glare shield is removed, it automatically swivels into a parking position which is located inside the thickness of the spectacle frame and in this position does not impair the handling of the spectacles, particularly when they are tucked away. Furthermore, a wide range of possibilities for a good design of the spectacles is left open. <IMAGE>

Title: Combination drainage system
Inventor: HELLE ROLF DIPL ING
IPC: E01H1/10
Filed: 1987-10-17
Abstract: The task of removing surface water has (e.g. in the case of tennis courts) until now been solved by means of hand sponges or sponge tampers. This old system is very laborious and time-consuming and is fundamentally improved in these respects by the "combination drainage system". The surface drainage is performed with the aid of the drainage hand roller (10, 4, 1, 11). The foam roller (1), saturated with water after use, is placed into the perforated trough (9) and squeezed out manually by the handle (7) with the aid of the trough lid (8). To achieve a sufficient counterpressure when the foam roller is being squeezed out, its axle (11) must have a minimum diameter of 5 cm. The water stored in the water tank (6) can be drained off via the closure (3) at any desired location.
