Abstract: 1491783 Method of preventing the removal of a fitting G E W LEWIN 27 Feb 1975 [28 Feb 1974] 8280/75 Heading F2H  A method of preventing the removal of a fitting attached to a support by at least one recessed screw 2 (or pin) having a head of diameter substantially equal to that of the recess 6 comprises inserting into the recess a member 10 the diameter of which, when in position in the recess, is substantially equal to that of the head of the screw (or pin). The member may be a pin which is knocked into bore 8 in the head of the screw, preferably in such a manner that the outer surface of the pin lies flush with the outer surface of the fitting. The shank of the pin may be furrowed, (Fig. 6, not shown). Alternatively, the member may be a disc, which is either concave, or embossed with or without a radially slotted circumferential edge (Figs. 7-12, not shown).

Abstract: A record carrier is described on which information is stored in an optically readable structure of trackwise arranged areas and intermediate areas. By giving the information tracks periodic excursions towards and away from adjacent tracks, in a direction transverse to the direction of reading, the period of the excursions being substantially greater than the average period of the areas and the amplitude of the excursions being smaller than the width of the tracks, a control signal for centering the read beam of radiation on an information track can be obtained without the use of additional optical means. The excursions of the tracks have such relative phase that the tracks are in nested concentric relation and one component of the stored information represents the phase of the undulations.

Abstract: 1529263 Smoke - generating devices FORENADE FABRIKSVERKEN 17 Feb 1976 [24 Feb 1975] 6156/76 Heading F3A A smoke-generating device with a rapid screening-off effect and an enduring screening-off effect comprises a combustible smoke-generating charge having portions for relatively rapid and relatively slow burning, the portion for relatively rapid burning having a larger ignitable surface area than the portion for relatively slow burning, and means for simultaneous ignition of the relatively slow and fast burning portions. In one embodiment, Fig. 2, the rapid screening- off is effected by igniting four cylindrical bodies 10 of smoke-generating composition with the aid of an igniting pellet 16 and a black powder layer 13. A body 11 of a smoke-generating composition is also simultaneously ignited, but burns over a smaller area than the bodies 10 and provides the enduring screening-off effect. In a similar embodiment, Fig. 3 (not shown), the rapid screening-off effect is provided by a stack of annular discs (17a, 17b) of smokegenerating composition, which discs are ignitable on both major surfaces by layers (20a, 20b, 20c) of black powder.

Abstract: A machine for transforming heat shrinkable thermoplastic material into sealed and liquid-filled containers in which the material in strip form is cut off to a suitable length then heated and transformed into a tube-shaped shell blank on a mandrel with an overlapped longitudinal heat-sealed seam. The shell is then displaced in relation to the mandrel so that its bottom end extends beyond the end of the mandrel, a base blank cut from another strip is then inserted into the end of the shell to rest against the mandrel end, and the shell and inserted base are then heated causing the shell to shrink accurately to the shape of the mandrel and the bottom edge zone of the heated shell to be folded in against the end of the mandrel and the edge of the base. The joined edge zones of the shell and base are then pressed together and heat sealed. The container is then passed to a filling machine where it is filled and closed by a lid.

Abstract: The unreacted gaseous vinyl chloride monomer still remaining in a polymerization reactor from which the polymerizate has been removed can be discharged by blowing steam into the reactor from its top so that the gaseous monomer is pushed downward and moved out from the bottom of the reactor, followed by a conventional treatment for condensation. This method of discharge serves to put the reactor open to the ambient atmosphere without the emission of the unreacted monomer and, as such, solve the problems of the workers' health and environmental pollution.

Abstract: Deflection control apparatus is disclosed for a beam index color television receiver of the type which includes a cathode ray tube adapted to display a video picture in response to a received color television signal. The beam index cathode ray tube is provided with index stripes which are scanned by the electron beam as the beam scans a raster across the display screen of the tube. A detector detects when the respective index stripes are scanned by the beam so as to produce an index signal, the frequency of which varies from a predetermined frequency value when the scanning speed of the beam varies. An oscillator generates an oscillating signal that is synchronized with the index signal, and a phase locked loop, which includes a comparator for comparing the index signal to the oscillating signal so as to produce a control signal as a function of the difference therebetween, adjusts the frequency of the oscillating signal in accordance with that control signal. The television receiver also includes a switching arrangement which is responsive to the oscillating signal to switch color information signals for the purpose of modulating the beam. The deflection control apparatus includes a deflection device for controlling the deflection of the beam; and a deflection signal generator responsive to the control signal produced by the phase-locked loop for supplying deflection control signals to the deflection device so as to vary the deflecting speed of the beam and thereby maintain a substantially constant scanning speed thereof.

Abstract: In a fish filleting machine with one pair each of circular belly filleting knives, back filleting knives and severing knives as well as belly and back guides arranged on the one hand between the former and on the other hand between the latter, the fish is saddled up tail forward on a push saddle. A scraper tool is disposed beside the belly guides downstream of the belly filleting knives and upstream of the plane of the severing knives, both halves of which scraper tool consist of a respective wedge-shaped scraper knife, the cutting edges of which are associated with a bulge-shaped backing support. The scraper tool is controllable in its height position. In that case, the scraper tool assumes a lowered, i.e. basic setting while the tail part of the fish is guided past. On arrival of the abdominal cavity end, it is driven into a raised setting so that the scraper knife after penetration of the uncut flesh band disposed laterally beside the backbone severs the fillets above the vertebral projections and ribs. The complete severing of the fillets takes place by the concluding severing cuts.

Abstract: The invention refers to a device for electric insulation between a heat-generating component (1, 1'), e.g. a diode, a transistor etc, and a heat sink (2, 2'). The component is mounted in the heat sink via a pressure or screw connection (4, 4') and the heat sink consists of one or more through connections (5, 5') for the union and/or electric connection (15, 16). A thin insulating washer (7, 7') is placed between the base section of the component (3, 3') and the contact area of the heat sink (13, 13') against the component. The device also consists of an insulating bus (8, 8') applied in the through connections (5, 5', 15) where insulation is required so that end surface of the bus (12, 12') is situated in the same plane at the contact surface (13, 13') of the heat sink against the insulating washer (7, 7'). In this way, the risk for damage from shearing is reduced in the edges of holes on the insulating washer and the risk for flash-over between the component and the heat sink is reduced.<IMAGE>
