Abstract: Peptides which inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads. Administration of an effective amount of such GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads. These peptides may be used to treat steroid-dependent tumors, such as prostatic and mammary tumors. The peptides include cyclic, bicyclic and tricyclic analogs of the decapeptide GnRH, and preferably there are at least two covalent bonds between the residues in the 4- and 10-positions, the residues in the 5- and 8-positions and the residues in the 1- and 3-positions, respectively. Examples of such bonds include a disulfide linkage between Cys residues, an amide linkage between a side chain amino group and a side chain carboyxl group, a dicarba linkage between side-chain alkyl groups, and a carba linkage between a side-chain alkyl group and a side-chain sulfhydryl group.

[Also in Division F1]  A fluid compressor comprises compressor means in a crankcase 12, a lubricant pump 50 supplying lubricant to the compressor means, and a lubricant sump 24 separate from the crankcase. To start the compressor 10, switch 80 is closed and a solenoid valve 72 in passage 70 opens to allow passage of gas from crankcase 12 into sump 24 to equalise the pressures. Time delay mechanism 84 then closes switch 85 to start the compressor. Oil pump 50 is driven by crank-shaft 20 and draws oil from sump 24 through line 56 with check-valve 58, and supplies it through passage 60 to bearings 42, 43 &c. Oil which accumulates in crankcase 12 is carried into sump 24 via passage 70 by gas leaked from piston 30, the gas then passing via passage 74 with check valve 75 into the piston cylinder 28 of the compressor. To shut down the compressor switch 80 is opened, thus closing valve 72 which, with valves 58 and 75, prevents flow of gas into the sump 24 while the compressor is inoperative.

Title: A peat-harvesting machine
Inventor: DELME JOHAN VILHELM RUDOLF
IPC: E21C49/02
Filed: 1981-06-22
Abstract: A peat-harvesting machine which is designed to be operated at low speed over the bog and to mill up the peat using a vertical circular milling disk 19. The milling disk 19 is mounted together with a peat press 22 on a back-and-forth constructed device 16 which swings transversely to the movement of the machine. The peat is thrown at high speed into the inlet of the press 22 where it is compressed into a strand which is then chopped into smaller pieces by means of a clipping device. The pieces fall on a transporter 28 which in turn takes the pieces on a long transporter 30 reaching across the machine, which in turn, after being filled with the peat pieces, dumps them on the ground through a tipping motion across its longitudinal direction. The peat that has been harvested at that time has very low moisture content and is suitable both as fuel and as raw material for extraction of coke, diesel oil, waxes, phenols, etc. <IMAGE>

Date Dec. 5, 1985.A movable hydrodynamic nozzle which removes deposits of sand, soil, sludges etc. in a pipe system. The nozzle is connected to a pressurized water pipe and pulls the pressurized water pipe into the pipe system. When known movable hydrodynamic nozzles are used, the cleaning efficiency is lower due to strong turbulence and frothing and to the fact that the resistance of the nozzle to the water flow is large. In accordance with the present invention this problem is solved by shaping the channels which guide the pressurized water from the main inlet portion of the nozzle to the outer back portion of the nozzle, in such a way that the pressurized water is entering the channels in the same direction as it has when it enters the main inlet portion. Additionally, the inlet openings and outlet openings of every channel are preferably diametrically opposed in order to give the channel an optimally large curve radius.
