Title: Improvements in rubber toys and other inflatable bodies
IPC: A63H3/06
Filed: 1929-08-02
Abstract: 334,352. Dorogi, L., Dorogi, I., and Dorogi Ús Tßrsa Gummigyar R. T., Dr. Aug. 2, 1929. Inflatable toys; animals and puppets. - Inflatable rubber bodies such as toys are provided with means for receiving stiffening or supporting elements to be inserted after manufacture, such means being air-tightly separated from the interior of the body. As shown in Fig. 1 in the case of a toy policeman, a rubber tube 26 traversing the interior of the body but not communicating with it, serves for the reception of a wire 4 which may then be bent to position the arms as desired. In the case of the feet, the edge seams may be partly unwelded to leave a tubular space 22 in which a wire may be inserted, the wire being then bent to dispose and retain the feet for supporting the figure. In another construction the edge seam may be turned up and again welded as shown in Fig. 15 in order to accommodate the guide tube 26. In a further variant the seam may be slit as in Fig. 14 to enable the stiffener 4 to be held in place.

Title: Leak-tight heat-insulating panel
IPC: G21C11/08
Filed: 1976-06-09
Abstract: 1500641 Thermal insulation COMMISSARIAT A L'ENERGIE ATOMIQUE 9 June 1976 [16 June 1975] 23900/76 Heading F2X A thermal insulating panel 20 comprises two parallel sheet-metal sealing elements 21, 22 welded together at their periphery 23 so as to form a leak-tight enclosure 28 in which is mounted a stack of alternate wire fibre or wire mesh elements 29 and perforated plates 30, 31 which extend parallel to the sealing elements 21, 22, the free spaces between the wire fabric or wire mesh elements 29 and the perforated plates containing an inert gas, e.g. argon, or a vacuum or partial vacuum. The sealing elements 21, 22 are each provided in the vicinity of their central portion with a hollow narrow portion 24 formed by die-stamping and terminating in a lip 25, and the elements 21, 22 surround a tube element 26 which is welded at the ends against the lips 25 by means of weld fillets 27. The plates 30 which are of greater thickness than the wire elements 29 have their holes 31 displaced from one plate to the next. A stud 19 for securing the panel to the surface to be insulated is engaged within the bore 32 of the tube element 26. A plurality of the panels 20, of square contour, are secured to the surface 18 to be insulated in successive layers. Each panel 20 is truncated at one pair of diagonally opposite corners, and the corners 33 of four adjacent panels 20 delimit a recess 34 for the passage of a stud 19 securing panels of a previous layer and a succeeding layer of the covering, the panels in the successive layers being displaced with respect to each other by one half-pitch. The elements constituting the panels 20 can have a radius of curvature obtained by die-stamping which permits the construction of curved panels adapted to the profile of the surface to be insulated. In an alternative embodiment (Fig. 4, not shown) the panels are of circular profile and the sealing elements have corrugations which extend in concentric circles about the centre of the bore traversed by the associated fixing stud. The overall effect of the corrugations is to achieve higher mechanical resistance to thermal shocks. The invention is described with particular reference to the insulation of the structures of a fast nuclear reactor, viz. the primary vessel, the inner vessel, the concrete vault roof, the vessel support strakes, and the sleeves through which reactor components penetrate into the primary vessel through the vault roof.

Abstract: 245,824. Stratton, F. F. Oct. 10, 1924. Addition to 228,969. Spray carburettors. - In the parent Specification, the fuel discharge from the pilot or slowrunning device is controlled by a conical or needle valve mounted on a spring-loaded piston subjected directly to the engine suction, the piston being adapted to slide in a cylinder projecting from the throttle valve casing and the invention consists in applying a similar control to the main fuel nozzle. The casing A contains the plug throttle valve B and has projecting radially therefrom cylinders A<2>, A<3> containing the control mean for the pilot and main nozzles F<2>, F<21> respectively. The maximum flow to each of the nozzles is adjusted by tapered needles H<1>, the fuel flowing through channels L, G<1>.

Abstract: 712,382. Restoring shape of drums &c. KRADOSKA, E. C. Sept. 26, 1952, No. 24195/52. Classes 83 (2) and 83 (4) Rolling.-A machine for removing dents and bumps from a metal body such as a drum having a bead or annular bulge comprises internal and external rolls one of which has at least one circumferential groove for accommodating the bead or bulge, means for moving one roll into operative position relatively to the other and means for rotating at least one of the rolls. The machine frame has a horizontal tubular arm 10 supporting a roll 12 with axially extending lugs 20 to which is bolted an extension 26 of the roll. A yoke 74 above the roll 12 carries two rolls 62, 64, the latter being driven by a reversible motor through a shaft 78 and universal joint 76. Each upper roll has a groove 68 to receive an annular bulge of a drum 28 and, adjacent one end, a smaller groove 66 to receive the end bead 130 of the drum. Rolls 62, 64 may be moved down to co-operate with the roll 12 by a compressed air cylinder 90 acting against a return spring 100. Opposite the grooves 68 is a gap between the parts 12 and 26 of the lower roll and in this gap is a plate 30 having a rim complementary to the grooves. The plate has comparatively large holes 32, Fig. 10, through which pass the lugs 20 so that normally the plate hangs down away from the grooves 68 when a plain part of the drum is being rolled. By moving axially a shaft 38 so that an enlarged end 44 thereof enters and engages a central hole of the plate, the plate is moved into a position concentric with the roll 12 from which it projects into the grooves 68 for reshaping a bulge. For reshaping an end bead, a member 118 may be lowered on to the roll 12 to form a stop against which the end of the drum is positioned. The chimb at the closed end of the drum may be rolled as shown in Fig. 13. The lower part of the drum is supported by a tilting frame carrying two rollers 108.

Abstract: 1,217,746. Angle modulated receivers. CONSIGLIO NAZIONALE DELLE RICERCHE. 22 May, 1968 [22 May, 1967], No. 24318/68. Heading H3R.  The invention comprises an arrangement for detecting sudden abrupt changes in phase in the output of a phase demodulator, being characterized by the steps of filtering out at the demodulator output a frequency band below the spectrum of the modulating signal and detecting in the filtered frequency transients due to the phase changes in the demodulator. At low signal levels, the output of an angle-modulation demodulator 1 comprising a multiplicative mixer 2 having as one input the signal to be demodulated and as the other the output of a locked oscillator 4 controlled from the output of amplifier 3 which is fed from mixer 2, can exhibit sudden jumps in phase, comprising 2# and multiples thereof as the oscillator 4 falls out of synchronism and is re-locked. The output of the demodulator 1 is fed via equalizer 6 to a low-pass filter 7 passing only frequencies below the modulation frequencies. Sudden phase jumps, constituting noise, are selected by a threshold circuit 9 and applied to a waveform generator 10 which pro- @es equal and opposite pulses. These are combined in addition circuit 11 with the signal, suitably delayed by passage through a delay line 8, to produce a signal in which the noise due to phase jumps is eliminated.
