Patent DE-4324589-A1 (DE)
Title: Electromagnetically operable pressure control valve
Inventor: SAUER JOSEPH
IPC: F15B13/044
Filed: 1993-07-22
Abstract: The electromagnetically operable pressure control valve according to the invention has a control piston (39) whose sealing piston sections (40, 41) are guided in a longitudinal bore (29, 30) of a distributor housing (27). In order to be able to control high hydraulic pressures even at low magnetic forces of the magnet part and at the same time guarantee a relatively large control-piston diameter which is thus simple to cope with in production, the piston sections (40, 41) have different diameters. Thus the control pressure applied between the two piston sections (40, 41) acts on two different effective areas at the piston sections. <IMAGE>
Patent DE-4325642-A1 (DE)
Title: Tractor with skidding tongs for towing logs of wood
Inventor: ROJAN WILLI AUGUST
IPC: A01G23/00
Filed: 1993-07-30
Abstract: The subject matter of the invention bears the title "tractor with skidding tongs for towing logs of wood". The tractors which are available on the market for logging longwood subject the forest soil to a very high degree of loading and thus constitute irresponsible environmental destruction. Either they have a very large inherent weight (clamp tractors) or destroy the forest soil due to the unbalanced load distribution on the rear axle. Tractors with load distribution on the rear axle are loaded, in daily use, to such an extent that steerability remains intact and virtually the entire loading is to be borne by the rear axle and thus simultaneously cause a large amount of damage to forests. In the case of my invention, the skidding tongs are designed such that logs of wood and skidding tongs, at the point in time where lifting is carried out, form a common loading arm and the bearing point of the skidding tongs can be selected such that the load is distributed uniformly on front and rear axles. With a low inherent weight, this spares the forest to the greatest possible extent. In this arrangement the design of the skidding tongs is improved considerably with respect to my application P 3744675.4-23. The bent skidding tongs are replaced by straight skidding tongs with cable-defining pulley. This gives more space to the hydraulic cylinders and great advantages as far as lifting the load is concerned.

Patent DE-4337593-A1 (DE)
Title: Multi-frequency method for transmitting alphanumeric messages
Inventor: BARTH UWE DIPL ING
IPC: H04L1/16
Filed: 1993-11-04
Abstract: To transmit alphanumeric messages via telephone connections, modem chips are in most cases needed as ancillary device. To provide for such a transmission by means of DTMF telephone terminals as transmitters and receivers and by means of two groups A and B/B' of a number of frequencies without ancillary device, a method has been created in which the transmitter first sends to the receiver a synchronisation signal which is acknowledged by a receiver ready for text reception, in which then a data format block transmission is carried out which begins with a start-of-text and type-of-information character and is continued with a variable number of information items and which ends with an end-of-text signal after a checksum check. In this arrangement, time blocks with three typical time windows are formed for the frequency changes. The receiver finally sends a positive or negative acknowledgement signal. This provides an economic possibility for the transmission of short text between DTMF telecommunication systems without ancillary devices.

Abstract: The object of the present invention is to provide a passively mode-locked laser which can achieve mode-locking of higher harmonics, a pulse repetition rate being produced which is comparable with that of known actively mode-locked lasers, without the complex modulation methods which are typically connected with active techniques being required. Exemplary embodiments of the present invention relate to a passively mode-locked laser, in which mode locking is achieved by splitting of the laser resonator based on harmonics or overtones. According to the present invention, relatively high repetition rates can be achieved, ultrashort pulses being provided, without the complex modulation methods of the active techniques being required, and without the laser being susceptible to instabilities which are typically connected with passive techniques, high repetition rates being achieved with the use of cavity subresonators.
