Title: Proximity switch
Inventor: HEIMLICHER PETER
IPC: G01S17/04
Filed: 1995-11-21
Abstract: The use of a single concave mirror (1) serving as an  optical focusing and directing element for a prox-imity switch allows to obtain an increased sensitivity at  equal construction size or to substantially reduce the  construction  size  with equal sensitivity.  In a preferred  embodiment,  the  concave mirror is divided into  two  halves  (3, 4) by the support plate (2) for the  light  source  (5)  and the light sensor (6), the halves  (3,  4)  of  the mirror serving the purpose of directing the emitted light (8) resp. that of focusing the  reflected  light  (9)  onto the light sensor.  In order   to  increase  the  resistance  to  difficult environmental  conditions,  the  concave mirror (1) or its  portions  (3,  4)  can be filled with a substance which is transparent for the light of the light source (5).    Metallized  plastics  material  is  a suitable material  for  the  mirror,  especially in combination with the mentioned filling substance.

Title: Nozzle including a venturi tube creating external cavitation collapse for atomization
Inventor: SINAISKY NICOLI A
IPC: F23D11/10
Filed: 1994-07-20
Abstract: A nozzle (20) for atomizing a liquid includes at least one Venturi tube (24) which defines a liquid flow path and has an entrance cone (27), an intermediate throat (30) of diameter dn, and an exit cone (31) having a length along the flow path to an exit port (32) of at least about 2dn. The exit cone (31) also has an angle of divergence that varies from 0 degree at the throat (30) to about 6 degrees at the exit port (32). As liquid with an entrained gas passes through the throat (30) with a Reynold's number greater than about 2300, the liquid static pressure reduces and the entrained gas forms cavities that grow. When the liquid emerges from the nozzle (20), the liquid static pressure rises and causes the gas cavities to collapse and to produce forces that are sufficient to atomize the liquid and to break atomic, molecular and crystalline bonds in the liquid.

Title: Improved meat product casing and method of shirring
Inventor: MERCURI ENRICO
IPC: A22C13/02
Filed: 1994-05-10
Abstract: This invention relates to a casing (10) for use in encasing meat products. The casing (10) comprises a combination of a first tubular casing (11) which may comprise a fibrous casing material and a knitted tubular net (12) located around and substantially concentric to the first tubular member (11). The tubular net (12) comprises circumferential elastic cords (13) and longitudinal cords (14), and the relative diameter of the circumferential cords (13) to the first tubular casing (11) are such that when the casing (10) is being filled the circumferential cords (13) are placed under tension prior to the first tubular casing (11) reaching its maximum diameter. This enables the circumferential cords (13) to absorb some of the hoop stress before it is applied to the first tubular member (11) thereby preventing splitting of the first tubular member (11) which might otherwise occur without the tubular netting (12). The specification also discloses a method of shirring the casting (10) to an injection nozzle (16) which enables even spacing of the tubular net (12) around the first tubular casing (11) as the casing (10) is drawn from the injection nozzle (16). The method involves inflation of the casing (10) prior to shirring onto the injection nozzle (16).

Abstract: A binary class library is adapted to provide full debugging type information particularly for use during program compilation in a minimal debug-generation mode. The library includes, a compile unit that #includes all the include files describing the classes that a given class library implements and exports. The compile unit also includes code defining a symbol with an external linkage. The resulting object module is put into the binary class library or a separate debug library. An inclusion direction and an external linkage symbol to the debug library are added to all include files for the class library that are #included by any program using its classes. These additions cause the compiler to direct the linker to add the debug library to the list of libraries from which it tries to resolve symbolic references, and to add a reference to the external linkage symbol that the linker will have to resolve by adding the debug library into the link.

Inventor: JEFFERS JOHN
IPC: H04M11/04
Filed: 1997-03-21
Abstract: A universal receiver includes a database of communication protocols which allow the receiver to configure itself for communication with the different panels. The receiver obtains certain information from the alarm panel which is initiating the communication. In the simplest form this is the DID number used by the alarm panel. The receiver uses this information to retrieve the appropriate protocol parameters stored in the database. The receiver can also add further identification codes to the address of the alarm panel for storage in a combined database serving many alarm panels. This allows convenient recording of communications received by the Security Station which serves different alarm panel systems some of which may have the same address code.
