Patent CA-1297726-C (CA)
Title: Size control system for stuffing machine
Inventor: LAMARTINO SALVATORE P
IPC: B65B9/15
Filed: 1988-04-15
Granted: 1992-03-24
Abstract: Abstract An apparatus for controlling the stuffed casing diameter includes shoes which ride against the stuffed casing to monitor its diameter.  These shoes drive a digital encoder which issues pulses representing deviations of the stuffed diameter from a predetermined nominal value.  A microcomputer processes these pulses and issues an appropriate control signal to a stepping motor for increasing and decreasing drag on the casing as may be needed to correct the stuffed diameter of the casing.  The microcomputer can include a delay so that each stuffed product is the reference for establishing the drag characteristics of the next product to be stuffed.

Title: Waveguide sensor
Inventor: SAWYERS CRAIG G
IPC: G01N33/543

Granted: 1992-06-09
Abstract: Abstract Waveguide Sensor This invention concerns assay techniques by which qualitative and/or quantitative detection of chemical, biochemical or biological species in a sample can be determined and also concerns sensors suitable for use in such techniques.  In particular it relates to a method of assaying for a ligand in a sample which comprises a)    incubating the sample in contact with the surface of an optical structure, said optical structure comprising a substrate with a first refractive index N1 and a surface layer with a second refractive index N2, said surface layer being such that, in use, a guided wave mode of resonant radiation may be propagated therein, and said surface layer having adsorbed thereon or bound thereto, either directly or indirectly, a specific binding partner for the ligand it is desired to detect; b)    irradiating the optical structure at an angle or range of angles to the normal; and c)    analysing the reflected, transmitted and/or propagated radiation in order to determin whether, and if desired the extent to which and/or rate at which, the guided wave mode characteristics of the optical structure are altered by formation of a complex between the ligand and the specific binding partner.

Abstract: A method and machine for the manufacture of packing containers of the type where a number of packing container blanks are successively converted to packing containers, open at the top, which are filled with contents, shaped and sealed. The packing container blanks are advanced intermittently during the processing and filling between the different stations, which means especially in packing machines with several conveying elements, that the driving unit of the machine will be unevenly loaded and that the working of the machine will be uneven and jerky. To overcome this it is proposed in accordance with the invention, that the driving of the different conveying elements should take place asynchronously in accordance with a similar but mutually offset pattern of movement. The one conveying element (6') will then be substantially at standstill during the advance of the second conveying element (6") and vice versa, as a result of which the driving unit obtains an appreciably more uniform torque curve so that uneven operation and consequent wear and noise can be prevented.
