Title: Tool cutting angle measurement arrangement, esp. for milling tool - has sensing element with rotary indicator plate which is brought into contact with the cutting surface
Inventor: ZANG VOLKER
IPC: B23Q17/09
Filed: 1991-03-14

Patent DE-4109385-A1 (DE)
Title: Air ring with multiple dies for segmental cooling of blown film bubble - has metering valves fed from common controlled source with relative exit pressure of more than 50 kilo:pascals, for improved control of thickness variations
IPC: B29C48/10
Filed: 1991-03-22
Abstract: Air ring for segmental cooling of blown film bubble with several radial dies, directed onto the bubble, each connected by a controllable metering valve to a common source of compressed air giving a relative exit pressure of at least 50 kPa. USE/ADVANTAGE - Precise and sensitive segmental control of cooling flow effect and thus control of thickness profile of film. Compared with DE2658518, this may be placed beneath the main air ring, so that its air flow impinges directly on the film instead of mixing with the outer layers of the main air flow, giving greater control effect with smaller air flow. Compared with US4443400, which is intended for deliberate broad variations in film thickness, this invention is supplied independent of the main air ring, so does not interact on the latter's supply. The high air supply pressure permits high exit velocities, little influenced by the main flow, despite appreciable pressure drop in the narrow dies. Compared with DE3743720, external valves give improved control over air flow compared with the former's variable die thickness (height) or radial piston. The convergence of the individual dies before entering the annular exit gap avoids abrupt transitions in air flow between air neighbouring dies compared with the radial walls of the prior art, while maintaining uniform air velocity over the majority of the die breadth. The die ring can be inserted additionally to the usual main cooling ring, pref. beneath it, to give film thickness correction with smaller flows and smaller absolute differences in air flow. The broad shallow dies (30) permit construction with small overall height. The arrangement can easily be retro-fitt
Patent DE-4110562-A1 (DE)

Patent DE-4124838-A1 (DE)
Inventor: MUENTNICH LEO
IPC: F16C33/46
Filed: 1991-07-26
Abstract: A roller bearing race (1) for a machine component (4) which can both run freely on a shaft (3) and can be coupled thereto has pocketed rollers (2) and a slot (7) permitting its radial extension at a peripheral position. The race (1) consists of two interconnected material layers (5, 6) acting as a bimetal strip with different coefficients of expansion. This arrangement makes it possible for the race to expand radially on a rise in temperature and thus transfer a force with a peripheral component to the rollers (2) so that the bearing rollers (2) perform a slight rotation about the shaft (3) even if the shaft (3) and the pinion (4) are coupled. This prevents damage to the races by the rollers (2) at high radial forces.
Patent DE-4129191-A1 (DE)
Inventor: ORTLIEB HARTMUT
IPC: A44B19/32
Filed: 1991-09-03
Abstract: The invention concerns a waterproof zip closure comprising two rows of teeth, each row being joined to a tape, the rows of teeth being brought into engagement with each other and separated from each other by a slide. In the vicinity of the rows of teeth, the zip closure has sealing means which, when the zip is closed, are pressed against each other, thus forming a seal.

Title: Coating and infiltration of substrates in a short time - by heating substrate using body which matches the component contour at gas outflow side and opt. gas entry side
Inventor: PEETZ KILIAN DIPL ING
IPC: C23C16/04
Filed: 1991-12-20
Abstract: To form a cpd. material, where a porous or fibrous substrate has a gas stream passed through it under a high temp. contg. a coating or infiltration material, the substrate is heated by a body which matches the component contour at the gas outflow side and, if necessary, at the gas entry side. Different heat levels can be applied to the substrate according to its shape and thickness. To coat the fibres of a substrate with one or more coating materials, heaters apply an even temp. distribution over both sides of the substrate. The heating at the gas entry is then switched off for an infiltration action with a further material. USE/ADVANTAGE - The system is used for coating and infiltration of substrates, with a short process time, and can process components with large surfaces and/or complex contours with an irregular geometry.

Title: Higher hydrocarbon sepn. from gas mixt. - by multistage condensation without using expansion turbines
Inventor: BAUER HEINZ DIPL PHYS DR RER N
IPC: C07C7/09
Filed: 1992-03-31
Abstract: Sepn. of high hydrocarbons from a gas mixt. also contg. low b.pt. components is carried out by a two or more stage condensation process in which: (a) prior to feeding into a first separator, the gas mixt. is cooled and partially condensed to obtain a higher hydrocarbon-rich bottm fraction and a lower b.pt component-rich top fraction; (b) the top fraction is partially condensed by indirect heat exchange with a refrigerant circuit, resulting in refrigerant evapn.; (c) the condensate is fed to a second separator to obtain a higher hydrocarbon-rich bottom fraction and a lower boiling component-rich top fraction; (d) the bottom fractions of the two and opt. further separators are combined as a product stream; and (e) the feed stream to any further separator is formed by the preceding separator top fraction which has been partially condensed by heat exchange with the refrigerant circuit. The refrigerant circuit may be designed as a cascade circuit or as a mixed circuit, e.g. a C3/C2 mixed circuit. ADVANTAGE - The process is efficient and flexible, can accomodate widely fluctuating gas mixt. parameters, and avoids the use of expansion turbines (and thus fluctuations with time) at any point in the process, so that process control is simplified.

Title: Yarn transport - has conveyor installation for the manipulation of various types of fully wound reels into and out of storage positions
Inventor: LANDMESSER PAUL
IPC: B65G47/10
Filed: 1992-07-10
Abstract: An installation for the manipulation of crosswound reels of yarn between transport and storage, has a distributor. This is constructed to select the type of reel being transported and then to manipulate them into the storage channel appropriate to the nature of the yarn. The selection can also operate in the reverse so that reels from storage positions can be placed on the transport system. A conveyor (2) suitable for the fully wound reels (6) has a belt to suit the reel in the horizontal position. These can be transferred (5) to a double round belt conveyor (10b) with drive motor (14) connected (14a) to a central control circuit (S). This enables sensors to count and direct the motion (6a,6b,16a,16b) of any particular reel in this section. The distributor (19) also has sensors and a drive to lift and swivel, taking from either direction (30a,30b,31a,31b). This enables reels to be delivered into the selected storage channels (32), or from these on to the conveyor (9). ADVANTAGE - The distribution of selected reels is carried out rapidly, esp. with an uninterrupted doffing process, or releasing one type of reel from storage.
