Title: Polarization-based coherent gradient sensing systems and methods
Inventor: DAVID G STITES
IPC: G01J9/02
Filed: 2016-05-31
Abstract: Polarization-based coherent gradient-sensing systems and methods for measuring at least one surface-shape property of a specularly reflective surface are disclosed. The method includes: reflecting a first circularly polarized laser beam from a sample surface to form a second circularly polarized laser beam that contains surface-shape information; converting the second circularly polarized laser beam to a linearly polarized reflected laser beam; directing respective first and se- cond portions of the linearly polarized reflected laser beam to first and second relay assemblies that constitute first and second interferometer arms. The first and second relay assemblies each use a pair of axially spaced-apart gratings to generate respective first and second interference patterns at respective first and second image sensors. Respective first and second signals from the first and second image sensors are processed to determine the at least one surface-shape proper- ty.

Title: Exhauster hood connection pipe - has port open to atmosphere closed by shutter under fan air pressure
IPC: F24C15/20
Filed: 1975-03-11
Abstract: The pipe is used for connecting a hood, equipped with a fan, to the ventilation conduit of a kitchen, etc., and has a port (6) connecting it freely to the surrounding space, and in conjunction with which a shutter (8) works. The air pressure from the fan (10) normally causes this to shut the port, but it falls open again as soon as the fan stops. The shutter can be accommodated in a chamber between the pipe and the conduit (2), and there can be a number of different unions in the chamber, and which can be shut, so that the pipe can be connected to it at several different angles. The chamber can be in the form of a conical piece between pipe (4) and conduit.

Title: Solid waste sepn. from effluent - in a rotating perforated drum with a gully to collect backflush water
IPC: B01D33/11
Filed: 1975-10-10
Abstract: The separator has a perforated drum which rotates on a horizontal axis. One end is virtually sealed by a radial wall. A spiral attached to the inside of the drum transports material towards the open end. A stationary feed pipe extends through the end wall. Liq. is sprayed on to the top of the drum to clear material lodged in the perforations. The spray and the drum are enclosed in a housing with an outlet for water. An open gully stretches from the open end of the drum, along its length. A transport spiral moves solids and water which collect in the gully towards the feed end of the drum. The process is used for sepg. solids esp. from fish or vegetable processing. The gully prevents backflushing water from the spray leaving the filter with the solids. The solids cost less to transport as their water content is low.

Patent NL-8300062-A (NL)
IPC: E05C17/04
Filed: 1983-01-07
Abstract: The manually releasable stop device permits unimpeded swinging of the window within a limited angle of rotation between the closed and partially open window. After releasing the stop device further swinging of the window is permitted beyond the limited angle of rotation. The stop device comprises two cooperating stop members (25, 26) which are fastened to respective support members (14, 18) in the window hinge which are pivotable relative to each other. A first stop member is constituted by a stop element (26) fixedly fastened to the one support member (14), and the second stop member is constituted by a self-locking catch element (25) fastened to the other support member (18). The catch element cooperates with a positive control mechanism (26, 32, 37, 39) in the pivotal region of the window within the limited angle of rotation. In the pivotal region the positive control mechanism is adapted to forcibly control the catch element (25) to engage with the fixedly fastened locking element (26), while the catch element in the pivotal region is designed for limited movement of the catch element relative to the fixed locking element.

Title: Closed (continuous) doctor (squeegee) with lateral seal
IPC: B41F15/44
Filed: 1991-12-18
Abstract: The invention describes a doctor for use in a rotary screen-printing device, comprising a doctor body 1, a printing paste feed pipe 2, a printing paste discharge chamber 3 and a printing paste discharge nip 4, as well as a printing paste feed duct 5. The printing paste feed duct 5 is provided with narrowed sections and widened sections 5a, 5b, 5c, which are left clear by doctor-blade retention means 7 and 8. According to the invention, the lateral seal used in a doctor of this nature is formed by space-filling means and doctor-blade compensation means. The space-filling means 30, 30', 30'' are of a form which is matched to the form of the narrowed sections and widened sections in the printing paste feed duct 5 and to the form of the printing paste discharge chamber 3. The doctor-blade compensation means are expediently formed by a strip-like material 14, 18, 36, 59, 60 which allows the gap between the inner wall of a stencil with which the doctor interacts and a space-filling means 30, 30', 30'' to be sealed. <IMAGE>
Patent NL-9300170-A (NL)
Title: Quick-release coupling for truss system
IPC: E04B1/58
Filed: 1993-01-27
Abstract: The invention relates to a quick-release coupling for connecting trusses to one another in a rapid, effective manner. Trusses are triangular or square structures which are used in the theatre and construction of stands for holding lighting and decorations. The coupling system which has been used hitherto comprises a piece of tube of relatively small diameter, which is fitted into the truss and secured by means of nuts and bolts. The connection brought about in this way has a number of significant drawbacks, in particular the fact that the load-bearing capacity of the structure decreases and the possibility of free spans is very limited, due to the play which arises. The new conical coupling connects the components in such a manner that it is impossible for there to be any play, with the result that the load-bearing capacity is considerably increased, while there is no question of bending even in the case of long spans. These extremely positive properties arise through the combination of various cones which ensure that the components are rigidly fixed together.

Patent PT-86777-A (PT)
Inventor: ROTHFUSS THOMAS
IPC: E04F15/024
Filed: 1988-02-17
Abstract: In frames consisting of sheet-metal sections (1) which have a bending edge at the edge with the tread plane because one leg (2) of the frame is bent round into the tread plane, this edge cannot be made sharp. Thus, when the panels are laid against one another, there is a small gap which, especially where thin hard floor coverings are concerned, can lead to a break of the floor covering at this point under a load exerted at a particular point. The sharp edge can be obtained, on the one hand, by designing the leg (2) as a sheet-metal part (5) bent back on itself, the free end of the sheet-metal part (5) coming to rest on the panel edge. Alternatively, it can be achieved in that a bead (9) formed in the sheet-metal section (7) in the vicinity of the respective panel edge is evened off in a tool in such a way that it forms as a result of the creep of the sheet-metal material. In the finished floor panel, the frame is filled with flowable hardening material. <IMAGE>
