Title: Multi-layer flexible sheet structure for packaging, a package made therefrom, and a method of making the said structure
IPC: B65D35/02
Filed: 1984-03-02
Abstract: A multiple layer sheet structure (10) suitable for making tubular squeeze containers, such as for dentifrice, incorporates a uniaxially oriented polypropylene layer (16) within 1.5 mils (0.038 mm) of a surface of the structure destined to be the exterior of the container.

thereon or into a catching means (10) from which the compos­
ition is recycled for re-use characterised in that the viscosity of 
the fluid composition is monitored and in that solvent or 
carrier liquid is added to the fluid to return the liquid content of 
the fluid to a desired value.

comprising a nozzle (2), through which a fluid composition is 
adapted to be ejected, in fluid flow communication with a 
reservoir (1) for that fluid, means for applying vibration to the 
fluid composition whereby fluid ejected from the nozzle is

deflection means (9) whereby the charged droplets are 
deflected to a desired extent so as selectively to fall upon a 
substrate to form a symbol thereon or into a catching means 
(10) whereby the droplets are caught for recycle to the reser­
voir (1), characterised in that the apparatus incorporates a 
means (14, 15, 16, 17) for monitoring the viscosity of the fluid

Patent EP-0134078-A3 (EP)
IPC: C12Q1/34
Filed: 1984-06-12
Abstract: The presence of beta lactum ring-containing cephalospo­
rins and penicillin is determined in biological liquids such as milk 
by contacting the test liquid with a beta lactum ring-containing 
chromogenic compound and penicillinase and measuring after a 
predetermined time period the colour developed in the test liquid 
in comparison with a colour standard. Preferably, the colour 
standard is provided by contacting the same ingredients and 
concentrations for the same time period, exept that the liquid is 
free of beta lactum ring-containing cephalosporin and penicillin. 
The colourimetric test can be carried out within a few minutes 
(e.g. 3-15) utilizing a chromegenic compound such as nitrocefin, 
preferably on a solid phase substrate. The penicillinase attacks 
the beta lactum ring of the chromogenic compound and any 
beta lactum ring-containing cephalosporin and/or penicillin pre­
sent in the test liquid. The generation of colour due to breakage of 
the chromogenic compound's beta lactum ring is correspondingly 
reduced as the concentration of the beta lactum ring-containing 
antibiotic increases in the test liquid. Therefore, the method 
permits measurement of the concentration of such antibiotic in 
the test liquid. The method is simple, inexpensive, rapid and 
effective and can be run on equipment which is readily available 
in most laboratories.

Abstract: A towed implement (10) is mounted in a tractor three-­
point hitch (14) by means of a hitch structure (12) which is 
immobilised against lateral movement whether the hitch is 
lifted or lowered. The implement comprises a transverse 
beam or frame (18) which is attached to the hitch structure

switches controlling the hydraulic actuator to maintain the 
implement correctly positioned relative to the crop rows 
being cultivated. The actuator holds the position of the beam 
(18) so that positional errors do not arise even on sideways 
sloping ground.
