Title: Delay detonator
Inventor: YUNAN MALAK ELIAS
IPC: F42B3/16
Filed: 1982-04-26
Abstract: improved uniformity of timing, and particularly reduced sensitivity of timing to minor variations in delay charge size, are achieved in delay detonators by placing a loose load of a flame-sensitive ignition composition between a pressed delay charge and an ignition assembly, e.g., a percussion primer, at the actuation end of the detonator. The loose ignition charge has a free surface and is adapted to be ignited in response to direct contact with flame emitted from the ignition of a charge in the ignition assembly. Preferably, the delay charge is pressed into a plastic carrier which, in a non-electric detonator, has an open end terminating between the walls of the detonator shell and a primer shell that closes the actuation end of the detonator, and the ignition charge is loosely loaded into a metal capsule seated against the delay charge.

Abstract: An insulated wire is wound into a cylindrical coil by being continuously introduced into an annular space between a cylindrical core and a cylindrical sleeve coaxially surrounding same above a supporting surface which is rotated about their axis at an angular velocity W, the wire being fed in at a linear speed V. A processor is programmed to vary the ratio V/W according to the relationship (V/W)i= pi [D+2d)(ai-1)] where D is the diameter of the core, d is the wire diameter and ai is an integer representing the order number of the ith turn of a spiral path, counted from the core surface, along which the wire is laid in a succession of flat layers piled one atop the other. Each layer consists of n contiguous turns following one another in a radially outward direction in odd-numbered layers and in a radially inward direction in even-numbered layers, with decrementation or incrementation of the ratio V/W at the end of each turn. The discharge end of a feed tube is raised above the supporting surface, upon the completion of each layer, by an incremental distance equal to the wire diameter d to accommodate the next layer.

Abstract: Fusion proteins containing  beta -galactosidase or a  beta -galactosidase fragment preferably having more than 250 amino acids, but significantly less than the total sequence of  beta -galactosidase, and a eukaryotic, genetically encodable polypeptide are insoluble and easy to isolate from bacterial cells. The purification of the polypeptides can be simplified by replacing interfering codons for methionine and/or arginine and/or cysteine in the  beta -galactosidase gene fraction by codons for other amino acids. Genetically encodable polypeptides can therefore be obtained by coupling the structural gene for the desired polypeptide in the correct reading frame, if necessary via an adapter, to a gene for such a  beta -galactosidase derivative via a regulation region, expressing the insoluble fusion protein in a bacterium, isolating this protein after cell disruption and liberating the desired polypeptide by chemical or enzymatic cleavage. The cleavage can be facilitated by adding a "polyamino acid arm", which is arranged between the polypeptide and the  beta -galactosidase component.

Title: Device for damping the movement of a piston as it approaches the end position in a cylinder
Inventor: JOHANSSON J
IPC: F15B15/22
Filed: 1978-05-31
Abstract: Device for damping the movement of a piston as it approaches the end position in a cylinder, consisting of a slide protruding from the surface of the piston facing the cylinder end wall, said slide being displaceable completely into the piston against the action of a spring, and placed and dimensioned such that it fully covers the orifice of a pressure medium draining channel in the end wall of the cylinder, when the slide is brought by the action of the piston into contact with the end wall of the cylinder. The slide has a through slit through which a retainer pin fastened to the piston extends in order to delimit the movement of the slide. The slit is in connection with a central axial bore in the slide, said bore opening into the end face of the slide within the border of the bore of the draining channel when the slide is covering the channel opening. By means of the slit, the pressure medium flow is choked and the piston movement is damped, firstly when the slide chokes the inflow in the channel opening when approaching same, and subsequently, when the slide is covering said opening, by the pressure medium being forced to flow out via the slit and the axial bore, whereby the pressure medium receiving portion of the slit becomes still smaller as the piston approaches the end wall, because of the slide being displaced into the piston bore.

Title: Method for processing of frequency-modulated information on a storage element and apparatus for processing of information in the form of a frequency-modulated signal on an information element
Inventor: WINSLOW J S
IPC: G11B7/00
Filed: 1978-09-27
Abstract: The invention concerns the method and apparatus for recording video information in the form of a frequency- modulated signal on a video disk element 10 and for recovery of the video information from the video disk element. The recording apparatus has a laser as a source 30 of a laser writing beam 29, 29' and an optical writing unit 40, 41 for directing the stationary laser writing beam against a moveable video disk element 10. The video disk element comprises a substrate 22, which carries a coating 26 that can be influenced by light on at least one surface 24. The optical writing unit 40, 41 focuses the beam into a tiny spot of light 42 with a diameter of around 1 micrometer on the coating layer 26 which can be influenced by light. The intensity of the focused spot can be altered under control by a light intensity modulating unit 44. This light intensity modulator 44 changes the intensity of the laser writing beam 29, 29' with respect to a predetermined threshold intensity, which is high enough to form a first type of markings 37 in the coated layer. The length of the first type of marking depends on the speed of movement of the video disk element 10 and the time during which the intensity of the writing laser exceeds the predetermined or material-dependent threshold intensity. When the intensity of the laser writing beam drops below the predetermined threshold intensity, the formation of the first type of marking 37 ceases. The intervening portions of the light-influenced coating layer that are situated between consecutive markings of the first type serve as a second type of marking 38. A motion control unit 28 rotates and translates the video disk element relative to the intensity-modulated writing light beam. In this way, a linear sequence of first and second markings is formed on the substrate. The first and the second markings 37, 38 have variable length and represent the frequency- modulated signal used for the recording. <IMAGE>
