Title: Fluid catalytic cracking process - with control of pressure drop in regenerator circuit by valve, at constant pressure difference between cracker and regenerator
Inventor: LUCKENBACH EDWARD C
IPC: C10G11/18
Filed: 1977-09-30
Abstract: In a fluid catalytic cracking process, catalyst contaminated with coke is fed to a regenerator via a circuit which contains a control riser, and the rate of catalyst circulation is regulated by injecting variable amts. of control gas into the riser; the press. drop across the control riser is varied within a range of 4 (0.3-3), esp. 1-3 psi by use of a valve, while maintaing the press. differential between the regeneration zone and the cracking zone constant. The control gas is pref. air. A constant press. balance between regeneration and cracking zones gives improved performance. Stable flow can be maintained over a wider range of catalyst circulation rates. There is less erosion of the valve.

Title: Tyre for vehicles endless track drives friction wheels - has polyurethane foam core which disintegrates when wheel works
Inventor: AUFLEGER PAUL DR
IPC: B60C7/10
Filed: 1979-08-07
Abstract: The cellular, foamed or otherwise porous structure forming the core of a tyre for vehicles, friction wheels, endless track driving wheels, etc. is brittle, and when running load is applied to it, it disintegrates.

Title: Formation of multiple layer of lignocellulosic fibres - by superimposition of single fibrous layers from short sec. conveyors
IPC: D04H1/593
Filed: 1979-08-31
Abstract: Equipment for the prodn. of a graded, multi-thickness layer of lignocellulosic fibres for fibreboard mfr. comprises a primary conveyor of non-porous material which receives the layers of fibres from a series of short secondary conveyors on which the fibres are laid down from individual hopper-spreaders. The secondary conveyors are porous and have suction channels beneath the upper run to intermingle and consolidate the fibrous layer. The secondary conveyors may be arranged one behind the other along the prim. conveyor, or pref. in a cascade series, each sec. discharging onto the one in front, the prim. conveyor receiving the completed layer. Arrangement replaces a single, long, heavily-stressed conveyor with a series of short, lightly-loaded conveyors. The life of the conveyors is thereby increased, and renewal is a less costly, lengthy, and time-consuming process.
Patent DE-2936295-A1 (DE)
Inventor: BARTENBACH CHRISTIAN
IPC: F21S11/00
Filed: 1979-09-07
Abstract: In the illumination of a room via conventional windows, the illumination level drops very sharply with distance from the window, because the bright zenithal light with an angle of incidence of less than 45 DEG  with respect to the vertical can become effective only in the immediate window region. If, by contrast, the zenithal light is refracted in a known way deeper into the room by means of a prismatic plate mounted on the outside and of a reflector plate, the result is an increase in the brightness contrast between the window opening and the environment. The arrangement is intended to reduce these frequently disturbing contrasts. For this purpose, an additional prismatic disc (6) arranged in the window opening (11) is used to refract the light beams (S) into the room (2) at an angle ( delta ) so high that they cannot strike the eyes of the people present in the room, but are reflected from the ceiling and/or high wall elements. <IMAGE>

Inventor: DELECKER WILLY-MAX EDUARD
IPC: E06B9/78
Filed: 1979-09-26
Abstract: Simplified manipulation of venetian blinds is combined with protection for the operating cords from dirt when they are handled with dirty hands. Provision for this involves a housing lower piece (1) and upper piece (7). The former is laid below the cords, while the latter is laid across them from above, and thrust in over the lower oiece to the point of semi-rigid locking action. At the front end of the lower piece, roller axle forks (1.b) may be divided at the centre of its width, if the rollers (2a-c) are divided, or sited at the outside edges of the piece in the case of a continuous roller. The piece can have longitudinal edge guide grooves. This permits rapid operation, without danger of the bottom weighted batten striking hard on the window sill.
