Title: Direct-acting locomotive brake
Inventor: RYCHLI WALTER DIPL ING
IPC: B60T15/14
Filed: 1988-05-09
Abstract: The direct-acting locomotive brake has a control unit 19a, 19b in the driver's cab, by means of which the compressed air actuation of a brake cylinder 18 can be controlled by way of a brake solenoid valve 8 and a release solenoid valve 12. The hand lever 20a, 20b of the control unit 19a, 19b can be adjusted from a middle neutral position I to one side into a braking position II and a succeeding full braking position III and to the other side into a release position IV and a succeeding full release position V. When the braking position II, the release position IV and the full release position V are set, the hand lever 20a, 20b automatically returns into the neutral position I whereas the full braking position III is latched and the hand lever 20a, 20b remains there after it is set to this position. In the neutral position I, not preceded by the full release position V, the pressure prevailing in the brake cylinder 18 at that instant is maintained, in the braking and full braking position II and III there is an increase in pressure and in the release position IV and the full release position V there is a fall in pressure or venting. When set to the full release position V, the brake cylinder venting is maintained by a self-retaining function for the release solenoid valve 12, even when the hand lever returns to the neutral position I and only when the braking or full braking position II or III are subsequently set is this self-retaining function cancelled, thereby terminating the brake cylinder venting. <IMAGE>

Title: Pin extruder
Inventor: KOESTER LOTHAR DR ING
IPC: B29C48/395
Filed: 1988-05-13
Abstract: Pin extruders having an exchangeable wet cylinder liner give rise to problems, for example for production due to the addition of error tolerances, in installation and when exchanging cylinder liners and due to different thermal expansions. These problems are solved in the case of an extruder according to the invention by the exchangeable pins being inserted into the wet cylinder liner, by their being no rigid connection between cylinder liner and cylinder shell at the points of the pins and by the liner, which is fixed at one end, being easily exchangeable after removing the pins through the openings in the cylinder shell which are closed during operation by screw covers. Such pin extruders are used for the mixing and homogenising of thermoplastics or elastomers. <IMAGE>

IPC: F24H1/22
Filed: 1989-01-03
Abstract: To heat the dwellings, predominately coal, oil and gas are burned in the boilers and stoves. All of these involve, as an intrinsic feature, environmental pollution and are problematical. In order to counteract this, the new electric boiler is to be used. The latter spares every dwelling occupant to a great extent the problems of smell, noise, space, transportation and risk of fire. The electric boiler is fully usable in most dwellings, small and large - and other facilities - in place of combustion-type boilers. It is space-saving and can be installed at virtually any place in the dwelling, especially the kitchen and bathroom, without heat losses. The heat from boiler and piping remains in the dwelling. It is easy to fit and maintain in operation and can be used almost without dirt. This quiet heating system is inexpensive to construct.
