Patent NL-8600880-A (NL)
Title: Coupling socket or elbow esp. for straight flue duct pure sections - has clearance around pipe, pipe stop, annular groove shorter than overlap and nearest insert end, and bore to inject self setting material
IPC: F23J13/04
Filed: 1986-04-08
Abstract: The system is intended for connecting straight pipe sections via a socket member, elbow or the like, particularly for a low-pressure flue gas duct. The pipe end is inserted in the member up to a stop and the overlap area of the member is provided with an internal annular groove and with one or more openings for injecting a setting material to fill the annular space between them. The length of the groove is less than that of the mutual overlap and the groove is nearer to the insert end of the member than to the inserted pipe end whilst there is a clearance between pipe and member such that, on injection, the material passes in both directions and emerges at the insert end before reaching the pipe end.

Title: Television display for images with differing aspect ratios - converts wide screen pictures to images which fit conventional television screen
IPC: H04N5/44
Filed: 1987-01-13
Abstract: The display circuit has a video signal processor and a picture tube (9) which has an image area detector circuit (11). The detector checks that the image aspect ratio, i.e. width/ height (B'/H), is 4:3. The video signal processor contains a compression circuit (7,37,39) which compresses the period of each horizontal line if a video signal with a different aspect ratio, e.g. 5:3, is detected. The compression circuit operates by converting the analogue video signal to digital form, storing it in line memories (37, 39) and reading it out to the display circuits at a different rate. A level-infilling circuit (21,31) in the signal processor ensures a uniform "grey" level dependent only on the image brightness.

Title: Intercom system through door panel - has multiplexed duplex audio channels as well as spy glass
IPC: E06B7/30
Filed: 1987-02-23
Abstract: Set into the panel of a door, e.g. a front door, is a rectangular case which has two main case parts with flanges. The two case parts are inserted in an aperture from each side of the door and fastened together using self-tapping screws. At the top of the unit is a 'spy-glass' which allows the occupier to see who is outside the door. When the occupier presses a push-button on the inside, a 9 volt battery is connected to amplifiers and a multiplexer which allow time divided audio communications via microphones and loudspeakers. A variant of the unit has an indirect spy-glass via mirrors for extra protection for the occupier.

Title: Relaxation oscillator with comparator bistable element - produces square wave output with minimal noise content
IPC: H03K3/0231
Filed: 1987-06-17
Abstract: The oscillator consists of a capacitor (1), fed by a charge and discharge circuit and a comparator flip-flop (5) which provides feedback. The charge and discharge circuit consists of a long-tailed pair of transistors (T3, T4) with a common emitter current source (14). One collector feeds the square wave output (u) across a load resistor (15), while the other charges the oscillator capacitor (1) whichis in parallel with another current source (13). The transistor bases are fed by the flip-flop outputs. The flip-flop (5) has a cross-coupling capacitor (c') which, together with the collector loads (10, 11) acts as a bandpass filter to eliminate noise. The flip-flop detects when the sawtooth signal (Vc) across the oscillator capacitor (1) is above a predetermined level.

Patent NL-9301467-A (NL)
Title: Method and system for the metered dispensing of products
IPC: B65B25/04
Filed: 1993-08-24
Abstract: To fill a container with damagable products which are supplied continuously, it is proposed to use a conveyor belt whose delivery end can be displaced with respect to the container. This displacement speed, with respect to the speed of advance of the belt, is such that it is possible to increase or reduce the supply of a product. This reduction in the supply of product may even be such that no products are supplied whatsoever, i.e. the delivery end is moved in the direction of backwards movement of the conveyor belt. In this way, it is possible to meter the amount of products which are to be supplied to a container extremely accurately without a product of this nature having to be blocked using all kinds of means which damage the product. Moreover, in this way it is possible to replace containers discontinuously while products continue to be supplied continuously.

Inventor: LESHER HAROLD DANIEL
IPC: C04B37/02
Filed: 1987-09-15
Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.
