Title: Device for surfacing by a spray of abrasive substance
Inventor: MOGUTNOVS ALEKSEJS
IPC: B24C5/04
Filed: 2000-09-18
Abstract: The proposed device for surfacing by a spray of abrasive substance is intended for cleaning of surfaces prior to painting, and it can be applied as a nozzle of sandblaster. It contains the body (3), air Laval nozzle (1) and the abrasive feeding nozzle (2) that is placed on the axis of air Laval nozzle (1). The novelty of an invention is characterized in that the feeding nozzle of the abrasive suspension is installed inside the Laval nozzle, both said nozzles forming altogether an annular channel of a hypersonic profile, the exit section of said channel being disposed in a plain of widening supercritical part of a Laval nozzle. Alternatives of realization of an invention are the following: the abrasive suspension feeding nozzle is shaped either as a cylindrical nozzle or as a Laval nozzle, or as a Venturi tube; the abrasive suspension feeding nozzle on an input end is bridged with the cylindrical chamber which form with the body of the device an annular channel, the wall of said chamber being provided with holes cut at straight or acute angle with regard to transport direction of the abrasive flow. Such construction of the device ensures that the abrasive suspension is delivered at the centre of spray and the high-velocity annular flow of air is delivered at exterior contour of nozzle. Such pattern of a spray results in magnification of an operating range of the device and derives high speed of an abrasive. The general view of the device according to an invention, in case the abrasive suspension and air are delivered by one and the same channel or sleeve, is shown in a figure 1.

IPC: E05B17/20
Filed: 1997-04-18
Abstract: The invention concerns disposable seals for sealing different objects, especially warehouses, wagons and containers. The patented seal consists of a fixer and a nozzle, which are joined by a flexible joining element made of a very durable material, in which both abovementioned elements are pressed. The fixer itself is a steel cylinder in a cylindrical crash resistant plastic coating with a small tip for fastening the joining element and a spring ring inside. The abovementioned nozzle is a steel rod with one end pressed into the joining element and the other end having a conical form and a ring-shaped groove. After the nozzle is joined to the fixer, the spring ring is pressed into the groove, thus ensuring the locking of the seal. Also, the joining element can be made of a steel rod with one end of a semicircular form, and the other end of a conical form with a ring-shaped groove, which is used for locking the spring ring of the fixer after the rod is joined with the fixer.Figure 2 illustrates the cross-sectional view of the seal with a flexible joining element (after locking).<IMAGE>

Abstract: A well coring apparatus (10) includes an outer barrel (12) and an inner barrel (18). The inner barrel (18) is sealed at one end with a sealing member (80) and has a reciprocating piston (70) disposed in the other end thereof. On O-ring (68) is disposed at the receiving end of the inner barrel (18) to provide a seal therefor. Spring members (76) provide a restrictive force to the piston (70). A sponge (50) is disposed around the inner walls of the inner barrel (18) for contacting the core (82). A fluid is disposed in the inner space (78) of the inner barrel (18) and pressurized. Reciprocation upward of the piston (70) causes the fluid to flow therefrom out the receiving end of the inner barrel (18). This flow of fluid washes the sides of the core (82) to prevent drilling mud from caking about the surface thereof and preventing proper transfer of fluids contained within the core (82) to the sponge (50). The fluid in the inner space (70) has a density that is lower than that for fluids external to the inner barrel (18) such that contamination of the sponge (50) is prevented.

Abstract: A batteryless, portable, transponder useful in a tag for a presence detection system. The transponder detects electromagnetic radiation at a first predetermined frequency and responds to said detection by transmitting electromagnetic radiation at a second frequency that is a subharmonic of the first frequency. The transponder includes an amorphous magnetic material component (48) for storing energy from the electromagnetic radiation detected at the first frequency for transmission as the electromagnetic radiation transmitted at the second frequency. In one embodiment (Figure 9A), the transponder includes a thin, flat ribbon (48) of low coercivity magnetostrictive amorphous magnetic material having a transverse uniaxial magnetic anisotropy defining a magneto- mechanical resonant frequency "f" in accordance with the dimensions of the ribbon, when in the presence of a magnetic bias field of a predetermined intensity, wherein the ribbon responds to the detection of electromagnetic radiation having a frequency "2f" by transmitting electromagnetic radiation at a subharmonic of the frequency "2f"; and means for biasing the ribbon with the predetermined magnetic bias field. In another embodiment (Figure 1), the transponder consists of a single resonant circuit including a nonlinear inductor (L1) having a core made of amorphous magnetic material; and a capacitance (C1) connected in series with the inductor to define the resonant circuit. The core of the nonlinear inductor includes an elongated thin, flat ribbon of low coercivity amorphous magnetic material. It has been observed that this resonant circuit exhibits a bifurcated frequency-division characteristic in relation to the amplitude of the detected electromagnetic radiation at the first predetermined frequency, whereby additional frequency divisions occur as the amplitude is increased. A coded tag (Figure 10) includes two amorphous magnetic material transponders (60, 62) that detect electromagnetic radiation at different frequencies.

Abstract: Textured animal protein can be prepared by forming a heated pressurised wet mass of animal meal and extruding the mass or otherwise reducing the pressure and temperature surrounding the mass. The ingredients for the animal meal are chosen so that the measurable gelatin content of the extruded product is less than 10% of the dry solids of the product. As gelatin is a hydrolysis product of collagen, this means that the animal meal should be prepared from material which is intrinsically low in hydrolysable collagen, or the hydrolysable collagen content should be reduced either by cross-linking (for example with propylene glycol alginate) or by hydrolysis and washing away the gelatin.

In a multistage transistor amplifier, the stages Tsl, Ts2, are directly coupled by Zener diode Szl, and a Zener diode Sz3 is provided in the D.C. negative feedback path to the first stage Tsl to stabilize the circuit against temperature changes. The last stage may be a common collector arrangement Ts3 directly coupled to the preceding stage with or without a Zener diode Sz2. Negative feedback obtained from the signal is applied via a network N to the emitter of Ts1. The path between the emitters of Tsl and Ts2 may include a capacitor and phase correction of the signal negative feedback may be achieved by including a circuit across the emitter resistor R11 of Ts2. The coupling Zener diodes Szl, Sz2 may be shunted with a capacitor and together with Zener diode Sz3 are biased to operate in the Zener region by -UB. Ferrite tubes may be coupled round the collector electrodes of the transistors so as to prevent parasitic oscillations at high frequencies. As shown the circuit is a wide band amplifier but it may be made frequency selective. Also the last stage may be a common emitter circuit.

Abstract: 1,256,831. Frequency analyser. INTERNATIONAL BUSINESS MACHINES CORP. 12 June, 1970 [27 June, 1969], No. 28511/70. Heading G4H. A frequency analyser converts an incoming signal to digital form representative of the amplitude of the signal at successive time intervals, stores the signals, reads the same signal out successively at repeatedly faster frequencies, converts it back into an analogue form and passes it through a band-pass filter so that the frequency distribution of the input is effectively swept through the frequency interval of the band-pass filter. An incoming signal is converted into digital form by A to D converter 11; it is then read into buffer 14 which may comprise a series of shift registers by means of clock pulses W generated by clock 15. When the input signal has been sampled for a preset period the write gate 12 switches off and read gate 17 opens. The contents of the buffer 14 is then read through repeatedly at successively faster frequencies F 0  to K n .F 0 , the result being fed back into the buffer via gates 17 and also being converted to an analogue signal by means of digital to analogue converter 20. The output is then fed through a band-pass filter and detector unit 21 to determine the frequency distribution of the input. In a modification the apparatus may be used for a multiplexing system, Fig. 3 (not shown), a single clock (15) drives a series of memory circuits of the type just described through a multiplexing switch. The outputs are then fed through a multiplexing switch to a digital to analogue converter and a band-pass filter (21).
