Patent EP-0018703-A3 (EP)
IPC: C22C37/08
Filed: 1980-02-11
Abstract: A camshaft manufacturing process wherein a camshaft is 
cast from a heat-treatable gray cast iron having a high carbide 
microstructure, is annealed while retaining the carbides and 
then cooled to room temperature. Surfaces, such as cam lobe 
surfaces, are then surface hardened and the camshaft may 
thereafter be machined. The heat treating process comprises 
heating the camshaft at 1600°F (871°C) in about twenty 
minutes, holding the camshaft at 1600°F (871°C) for about 
twenty minutes and thereafter heat treating the camshafts at a 
temperature of 1600° to 1640°F (871 to 893°C) for about eighty 
minutes. The camshaft are then cooled rapidly to about 
400°F (204°C), for example, within about an hour and a half, 
and thereafter air cooled.
Patent EP-0042613-A3 (EP)
IPC: F28F13/00
Filed: 1981-06-22
Abstract: Apparatus and a process of heat transfer employ a fluid 
flow passage in which the flow consist of non-turbulent 
boundary-layers adjacent the surfaces and a non-turbulent 
core-layer between the boundary-layers and interfacing 
therewith. An interrupter-structure is disposed within the 
flow passage and interrupts the full development of the 
boundary-layers at a multitude of spaced spots, leaving the 
heat transfer surfaces unaltered, unmodified and uninter­
rupted, so that the boundary-layers cannot increase in 
thickness but will partially separate from the surfaces and 
mix non-turbulently with the core-layer to effect the required 
heat transfer between the walls and the fluid. The interrup­
ter-structure preferably consists of a plurality of spheres, or a 
sheet in which spherical, elliptical, drop-shaped or egg-­
shaped protrusions have been formed, all of which can be 
obtained readily on the market place at very low cost. This is 
to be contrasted with prior art apparatus which increase the 
heat exchange by rendering the fluid turbulent e.g. by 
turbulence promoters or roughening, ridging or interrupting 
the heat transfer walls. The increased turbulence increases 
heat transfer but produces a proportionally much greater 
increase in pumping power that makes these proposals 
uneconomic for many applications.

Title: Drive mechanism for the drive axles of railway vehicles
IPC: B61C9/52
Filed: 1981-08-07
Abstract: In a propulsion unit for the driven axles of an electrically-powered rail vehicle, the torque of an electric propulsion motor is transmitted to the respective driven axle by way of a torque transmitting mechanism including gears and couplings. A common housing in the form of a hollow beam is used to enclose the propulsion motor, a bearing system, and a transmission. Cut-outs are provided in the sides of the housing to allow space for the driven axles. In order to increase the flexural and torsional stiffness of the propulsion unit, the hollow beam includes an annular end surface through which the propulsion motor and torque transmitting apparatus are inserted. The hollow beam not only forms a common housing or the propulsion components, but is a very stiff support element that reduces vibration and improves the running behavior of the propulsion unit.

Title: Reflector for a tubular lighting element
IPC: F21V7/00
Filed: 1984-10-26
Abstract: This invention discloses a lighting installation which 
employs a reflector shield of a certain shape which is de­
signed to provide non-directionalized reflection of light 
back into the room which would otherwise be lost towards 
the ceiling around the installation. The reflector (1) has a 
highly reflective surface and comprises an elongate mem­
ber having two wings (4) disposed symmetrically about a 
line (5) at which they join together. Each wing (4) has a plu­
rality of facets each running the full lenght of the wing and 
which are positioned at gratatory angles to one another so 
that the light from the lighting element is reflected down­
wardly and diffusely therefrom. This reflector maximizes 
the reflection of the light and reduces the number of light fix­
tures required.
Patent EP-0147098-A3 (EP)
IPC: G02F1/1335
Filed: 1984-12-05
Abstract: A method and an apparatus provide an optical switching 
system (100) which maintains essentially constant transmis­
sivity at its maximum value and develops independent of 
viewing angle two system optical transmission states of 
substantially contaminant-free light. The system includes 
first and second light gates (102 and 104) of which each has 
associated therewith contaminant light intensity patterns (48 
and 66) with points of local maxima (54, 56, 58, 60, 68, and 
70) and local minima (62 and 72) in two system optical 
transmission states. Quarter-wave plates (134 and 136) are 
positioned between the light gates to develop circular 
polarization of light propagating between them. The pre­
sence of circularly polarized light maintains the system 
transmissivity at its maximum value while the relative 
orientation of the light gates is changed to align their 
contaminant light intensity patterns to block the transmis­
sion of contaminant light, and thereby improve the viewing 
angle performance.

Title: Process for producing white and coloured resists on polyamide fibrous materials
IPC: D06P5/12
Filed: 1985-10-19
Abstract: In the conventional discharge printing on polyamide fiber materials using acid dyes, above all, the very low wet and light fastness properties of the designs obtained in this manner are frequently an obstacle to the wide expansion of this interesting technique in practice. Applying this known patterning method for wool or nylon to resist prints made with reactive dyes being distinguished by better fastness level, does not always produce satisfactory white resist effects when, for example, sulfite compounds as the resist agent and reactive dyes having esterified  beta -hydroxyethylsulfonyl groups as the reactive radical are taken into consideration; colored effects having a bright hue are not even possible at all in various cases. It has now been found that, using sulfite compounds and reactive dyes of the vinylsulfonyl type, the above mentioned difficulties can be remedied when, instead of the ester derivatives of said dyestuffs, according to this invention such dyes which have been converted before they are applied into the free vinylsulfonyl form, are brought to interaction with the preprinted resist agent to become immediately and completely desactivated and thus resulting unobjectionable resist effects at the respective places of the textile material.
