摘要:
A finger follower lever of a valve train, which has a lever body that is a pressed and punched component made of sheet metal and has a U-shaped cross-section with two largely parallel side walls. A roller rotatably mounted between the side walls on a pin. The pin is uniformly hardened and inserted at each end into a hole punched out of the side wall and is staked or caulked at the ends. To enable the holes to be punched out simultaneously in opposite directions of a relatively narrow lever body, at least one of the two side walls has, at least on the outside thereof, a flat recess in the region of the hole.

The invention relates to a finger follower, or lever (1) of a valve train, for example of a piston-type internal combustion engine, with a lever body (2) having an end-sided base web (4), on which there is a spherical cap-shaped bearing cup (8) for an articulated mounting on a bearing pin of a housing-sided support element, said bearing pin terminating as a spherical cap; and on this base web is fastened a retaining clamp (9), engaging with an annular groove of the bearing pin, in order to secure the finger follower (1) on the support element in such a way that said finger follower can move to a limited extent.

The invention relates to a measuring device for measuring the temperature in a reactor container which can be crossflown by bulk material, in particular in a solid phase polycondensation, which takes place in an SSP-reactor. The aim of the invention is to protect the measuring device against mechanical stresses. Said aim is achieved by virtue of the fact that the measuring device, which is used to measure temperature, comprises at least one metal profile, at least one measuring tube and at least one sensor which is arranged therein. The metal profile can be connected to the walls of the reactor container and the measuring tube is connected to the metal profile such that it is partially reinforced on the external wall thereof by means of the metal profile. As a result, the measuring tube is soldered, screwed, riveted or rigidly connected in another manner to the metal profile. The metal profile is then secured to the inner wall of the reactor container. Another advantage thereof is that the weight, which is exerted on the column of the bulk material, is partially applied to the SSP reactors which are equipped with the measuring devices.

A parallel spinning process, in particular for filaments, e.g. for textile or industrial applications, made from polymers such as, for example, PET or PA, in each case having a thread interlacing device between two godets for each individual thread, the godets being moved in relation to one another during the piercing or feeding operation in such a way that each individual thread is automatically threaded into its interlacing device associated therewith, and the angle of wrap in the operating mode is at least from 85° to at most 200°, preferably from 175° to 185°.

The invention encompasses a method for the stereoselective synthesis of alkyl proline and other amino acid derivatives which are intermediates of the farnesyl-protein transferase inhibiting CA.sup.1 A.sup.2 X motif of the protein Ras. The instant process employs an efficient diastereoselective �2,3!-Wittig rearrangement of .alpha.-allyloxy amide enolates mediated by a chiral auxiliary to provide acyclic and cyclic precursors.

To effect the adjustment, the expansion valve is first set for a basic coolant (R.sub.o) to a substantially constant static overheating temperature (.DELTA.t.sub.oh) in a predetermined working range of the evaporator temperature and, when the coolant circuit is filled with a replacement coolant (R.sub.1, R.sub.2) differing from the basic coolant (R.sub.o), the pretension of its adjusting spring (46) is adjusted in accordance with a specification suited to the difference between the vapor pressure curves of the replacement coolant and those of the basic coolant.
摘要:
A cam follower for a valve drive of an internal combustion engine. The cam follower has a housing and a cam roller. The cam roller is arranged between the side walls of the housing and is mounted on a journal which bridges the side walls. The cam roller, which has an outer ring, a rolling body set and an inner ring, is a combined plain and rolling bearing. The outer ring and the inner ring are in sliding contact with one another, and the rolling body set is arranged between the inner ring and the journal.

A hydraulic flow control valve allowing easy adjustment of fluid flow for a variety of hydraulic attachments is disclosed. The hydraulic flow control valve comprises a spool and a flow rate setting adjustment device configured to adjust a flow rate setting of the hydraulic flow control valve by adjusting the amount of travel allowed for the spool. An associated method of operating the hydraulic flow control valve is disclosed.
