Patent EP-0316329-A1 (EP)
Title: Packaging.
Inventor: GARWOOD ANTHONY JAMES MURRAY
IPC: B65B31/02
Filed: 1987-07-30
Abstract: A method of packaging goods including placing goods such as meat over a base, applying a flexible web of gas permeable skin wrapping plastics material over the base and the goods, evacuating air or gas from between the base and the skin wrapping so as to allow the skin wrapping to flexibly displace onto the goods and to at least partially skin pack said goods. A lid is then applied over the skin wrapping and spaced therefrom. A gas is provided in the space between the lid and the skin wrapping to enhance the keeping properties of the packaged goods by permeating the skin wrapping. The lid is sealed to the base so that the space is permanently retained, the skin wrapping is attached relative to the base. Following discoloration of the packaged goods over a period of time, a fresh gas is allowed to enter the package and contact the surface of the goods within the skin wrapping without removal of the skin wrapping, whereby the color of the goods is improved.

Abstract: Combustion-tube holders provided in particular for compact lances can be designed to be compact and reliable, in particular in combustion tubes having small diameters, by a bush being provided between the grippers and sealing sleeve. This bush is axially displaceable inside the inner bore of the handle but is secured in the radial direction, in which arrangement, in particular in this secured position, it has an effect on the grippers, i.e. it also locks the same. This safety device against rotation is formed in particular by an elongated hole in the bush and a radial bore in the handle having an inserted shank screw. Advantageous coupling and securing of the combustion tube inside the combustion-tube holder is thus effected by turning the shank screw down onto the outer circumference of the combustion tube. Furthermore, a particularly reliable gas-return and slag-return preventer and a quick-acting valve designed to permit ease of flow are provided in the handle. The quick-acting valve is actuated via an operating lever of ergonomically advantageous design.

Abstract: A line synchronising circuit in a picture display device, which circuit comprises a phase control loop including an oscillator and a phase comparison stage. In order to enlarge the capture range of the control loop, the phase comparison stage is in the form of a phase frequency detector having a trigger action on edges of pulses applied, the circuit being provided with means for inhibiting the supply of the control signals during a predetermined duration after establishing that the phase difference measured by the phase frequency detector between the local signal and the incoming line synchronising signal is larger than a predetermined value. In the said duration the oscillator signal has sub­stantially the same frequency as before establishing that the phase difference measured by the phase frequency detector is larger than the said predetermined value. The supply of the control signal is restored during a second predetermined duration after the supply of the control signal has been inhibited, and this irrespective of the phase difference between the local line signal and the incoming line synchronising signal.

Abstract: The system controls a friction element for limiting a speed of rotation equaliser between the axles of a two-axle and/or four-wheel drive vehicle as a function of the difference in the mean wheel speeds of both axles (speed longitudinal difference); this is compared with two speed of travel-related tolerance bands, the first determining positive and the second negative speed longitudinal differences. If the values for the speed longitudinal differences lie above the first or below the second tolerance band, the limitation is increased, if the values lie within the tolerance bands, the instantaneous limitation is retained and in the case of values lying between the tolerance bands the limitation is reduced. The system can also be expanded to include an adaptation facility for limiting criteria in respect of different rolling radii of the wheels and a curve correction facility.

Abstract: Beim Einladen von Containern in Flugzeugfrachträume ergibt sich das Problem, daß die Container nicht nur quer zur Längsachse des Flugzeuges in den Frachtraum hineinbewegt sondern gleichzeitig auch um 90° gedreht werden müssen. Zur Vereinfachung der erforderlichen Antriebseinheiten wird eine Antriebsrolleneinheit (99) beschrieben, welche zwei drehend antreibbare Antriebsrollen (1, 1') besitzt. Diese beiden Antriebsrollen (1, 1') sind in ihrer Axialrichtung nebeneinander angeordnet und stehen beide in Arbeitsstellung mit dem Boden des Containers (100) im Eingriff. Eine Motoranordnung (25) zum Antrieb der Antriebsrollen ist mit diesen über ein Differentialgetriebe (31) gekoppelt, wobei der eine Ausgang (40) des Differentialgetriebes (31) die eine Antriebsrolle (1) antreibt, während der andere Ausgang (35) des Differentialgetriebes (31) die andere Antriebsrolle (1') antreibt. Diese gesamte Anordnung ist um eine vertikale Achse (15) drehbar gelagert und es erfolgt eine vorbestimmte Abbremsung sowohl der Ausgleichszahnräder (33,34) des Differentialgetriebes (31) als auch der Drehung um diese vertikale Achse (15). Es wird dadurch erreicht, daß bei Abbremsung des Containers während des Einladevorgangs eine Drehbewegung herbeigeführt wird, die dem Container schrittweise um 90° in die gewünschte Lage bringt.

Abstract: Process for synchronization of a frequency to an interference-prone reference frequency. Loss of the steady-state phase relationship between frequency and reference frequency which is maintained during the control process because of either phase shifts or necessary switching to another reference frequency causes a permanent phase deviation (random walk) in some cases because of the interference-prone reference frequencies until the steady-state phase relationship is restored. In order to prevent random walk or to avoid having to terminate the phase relationship, initially an offset value is generated by the microprocessor upon occurrence of a phase shift which exceeds a predetermined threshold and prevents the effect of the phase shift on the control process, and secondly, each reference frequency is assigned its own phase discriminator by means of which the trend in the phase relationship of the frequency in comparison with each reference frequency is known by the microprocessor, so that the microprocessor can take suitable control measures in the event it is necessary to switch to a different reference frequency.
