Title: Refrigerating appliance with an improved defrosting device
Inventor: FUMAGALLI NISO
IPC: F25D21/00
Filed: 1986-07-22
Abstract: A refrigerating appliance has an electric-resistance defrosting device which is activated at the end of a time period preset by means of a timing member 17. The timing member 17 is stopped when the electric resistance 6 is activated and is started again when the resistance 6 is de-activated by a thermostatic sensor 7 which is able to detect the temperature of the evaporator 3. The result is that the time intervals between two successive defrosting cycles are kept constant, while the duration of each defrosting cycle is made variable. The refrigerating appliance also has a compressor 2 which, due to the switching arrangement thereof, is de-activated on the resistance being activated and vice-versa. A fan 5 in normal operation blows air over the evaporator 3 but prior to a defrosting operation the fan is de-activated. <IMAGE>

Title: Apparatus for measuring mechanical characteristics of steels
Inventor: ZATSEPIN NIKOLAI NIKOLAEVICH
IPC: G01N27/72
Filed: 1986-08-12
Abstract: The apparatus comprises two U- shaped electromagnets 4, 5 with coupled windings and a resonant magnetisation sensor 8 in the plane of the magnet poles. A control unit 19 drives the electromagnets directly or controls main and auxiliary demagnetising units 14, 16 and controls amplifier 26 and display 31 connected to the output of sensor 8. The sensor has an AC driven winding 9, cores 10, 11 and a measuring winding 12 and its output is connected via amplifier 26, memory 29, and display 31 to threshold circuit 34 which classifies the steel as hard, normal or mild. In operation sine wave AC fed to input 43 of control unit 19 demagnetises the steel using main demagnetising unit 14. Magnetising pulses are then fed separately to the two electromagnets and the resulting magnetism is sensed by pole 12. The steel is then demagnetised using the auxiliary demagnetising unit 16. <IMAGE>

IPC: H03L7/00
Filed: 1987-07-06
Abstract: The object of the invention is to provide a method and a circuit by means of which the signals generated in a stationary base station (1) and a flying station e.g. missile (3) can be regulated to a common frequency. The frequency of the signals generated in the base station (1) is adjusted to the frequency of the signals generated by the flying station. To perform the method the base station (1) uses a circuit (2) having a frequency generator (5) whose control input is connected to a first mixer (6) via a series circuit consisting of a converter (8) and a filter (14). The signal input of this mixer (6) is connected to two receivers (9, 10) which receive at least two different frequencies (fP) (fRP) in order to determine a control signal for the frequency generator (5). The flying station (3) has a frequency generator (40) whose output is connected to at least one mixer (41). The second input of mixer (41) is connected to the reception antenna (43) via a receiver (42). The output of the mixer (41) is connected to the transmission antenna (45) via a filter (44).   <IMAGE>

Title: Panel lifter
Inventor: GODFREY DAVID GEORGE
IPC: E01C23/12
Filed: 1987-10-15
Abstract: A device for lifting a ventilated floor panel has a generally planar base (12) which supports two depending pins (18, (24). One pin (18) depends from a slot (32) in the base in which the pin is movable towards and away from the other pin (24), pin (18) being lockable in a selected position in the slot by means of a nut (20). The other pin (24) is eccentrically mounted to a spindle (28) which is rotatably mounted in the base (12) and has a manual handle or lever (30) by means of which it can be rotated. Both pins are provided with rubber sleeves (22). In use, the pins (18, 24) are located in suitable holes in the panel, pin (18) being adjusted in slot (32) to accommodate the panel and locked in position. The spindle (28) is then rotated by handle (30) to cause pin (24) to grip the panel between itself and pin (18). The panel can then be lifted out of position when the device is lifted using handles (14). The device therefore provides a quick and easy way of removing ventilated panels. <IMAGE>

Title: Forming metal film patterns on substrates
Inventor: HINSLEY CHRISTOPHER FREDERICK
IPC: H01Q1/38
Filed: 1988-06-29
Abstract: A method of forming a metal film pattern on a substrate, comprising forming a positive or negative image of the pattern, applying that image to the substrate by depositing a material thereon, coating the substrate with a metal or metal alloy film e.g of:- gold, copper, silver, aluminium, brass or beryllium copper), in an ion deposition process and applying a solvent to the metal coated substrate so as to selectively remove metal from regions thereof to leave the desired metal film pattern on the substrate. The image is applied to the substrate in a dry toner photocopier and formed thereon in a fused ferrite filled styrene acrylic copolymer plastics material. The pattern of metal tracks may be formed on more than one surface of said substrate. The image may be either a positive or negative image of the pattern and the solvent be selected to remove the metal film adhering to the substrate (e.g. methyl alcohol) or to the fused toner image (e.g. acetone, methyl ethyl ketone, xylene or toluene). The substrate may be porous or non-porous.

Abstract: 890,828. Bridge circuits. VIBRO-METER G.m.b.H. July 25, 1960 [July 29, 1959], No. 26745/60. Class 37. An A.C. bridge circuit comprises balancing impedances 2, 2<1> connected in parallel with series windings 3, 3<1> of a common core transformer 7, the other symmetrical windings 8, 81 of which are connected in parallel with the measuring impedances 9, 9<1>, one or both of which is variable.

The initial unbalance of impedances 9, 91 in bridge portion II causes current to flow in transformer 6, the balance in the portion I being restored by varying impedances 2 or 2<1>. Measurement variation in 9 or 9<1> is then transmitted and current flows in the load 4 where it may be amplified and indicated by a suitable instrument. All the transformer windings may be tapped to give current and impedance matching. A full bridge comprising four arms may be connected in bridge portion II, auxiliary arms 12, 121 being connected to change-over switch 10 and serving as temperature compensators &c. The primary windings of a differential transformer may replace impedances 9, 91, a secondary winding being connected to winding 11 of transformer 6.

Title: Identifying specific objects or zones
Inventor: SMITH MARTIN PHILLIP
IPC: G01N21/86
Filed: 1989-05-05
Abstract: In order to identify specific objects such as diamonds (or zones of an article), the objects 2 are subjected to an exciting radiation chosen such that the objects to be identified emit a weaker luminescence which is characteristic of the object and a stronger luminescence which is less characteristic of the object. The weaker luminescence is detected using a large aperture optical system 6-13 and a photo-multiplier tube 14. The stronger luminescence is detected more directly using a CCD array 20 or 20', which locates the track on the conveyor belt 1 from which the signal was emitted. In accordance with the track, the appropriate sort jet 23 is actuated when the PMT 14 and the CCD array 20, 20' give simultaneous signals. <IMAGE>
