Abstract: 616,780. Hinges. ILLINGWORTH & CO., Ltd., E., and WHITE, I. E. Jan. 31, 1947, No. 2966. [Class 65 (ii)] A hinge, particularly for the lid of a box, comprises a member with resilient jaws and a member with a non-circular part fitting between the jaws and arranged to force them apart during its rotation. In the form shown a spring steel plate 1 is divided by cuts into a number of tongues, of which alternate ones are bent as at 3 to receive a bar-like portion 16 on another plate 12; the other tongues, such as 4, of the plate 1 bear on the bar 16, which is arranged at an angle to the plate 12 so that it lies against one side of the socket portions 3 when the hinge plates are in line and against the other side when the plates are at right angles, the movement from either position to the other being at first resisted and then completed by the pressure of the tongues 4. The tongues 3 pass through apertures in the plate 12 and may be shouldered to limit the opening of the hinge. Both plates are formed with prongs 11 to fix them in slots in the box and lid, which are preferably of thermoplastic material which shrinks on the hinge plates on cooling. The hinge plates may alternatively be riveted, welded, or soldered to metal container parts. Reference has been directed by the Comptroller to Specification 5695/40, as open to inspection under Sect. 91.

Filed: 1973-01-22
Abstract: 1423311 Proximity switch R BUCK 22 Jan 1973 [22 Jan 1972] 3121/73 Heading G1N A proximity actuated switch unit 1, is joined by an external lead 2 to a pole 3 of a voltage source 4 and by only one other lead 5 to a load 6 and comprises an oscillator 10 arranged to be inductively coupled by proximity of an external object e.g. a metal object; a thyristor 12 controlled by the oscillator via a triggering stage 11; a feed circuit 13 for the oscillator and triggering stage having a Zener diode 16 connected between the cathode 14 of the thyristor and the negative pole 15 of the D.C. which is to be switched by the thyristor, an auxiliary resistor 17 of a relatively high ohmic value e.g. 150 K#, a reservoir capacitor 18, a coupling diode 19, the cathode of the thyristor being triggered in use to turn-on the thyristor by connecting the cathode of the thyristor through a path of relatively low resistance, formed by a cathode resistor 28 (1 K#) and the collector-emitter path 23 of a triggering transistor 24 to the negative pole 15 of the D.C. supply, and the gate 20 of the thyristor being connected to the reservoir capacitor 18 to provide a potential only slightly above that of the negative pole 15 but sufficient to turn on the thyristor. It is stated that no voltage higher than the Zener voltage of Zener diode 16 is needed to turn on the thyristor and that no voltage spikes such as those represented in outline in Fig. 3 (not shown) are obtained. Fig. 3 represents the total voltage drop across a switching unit as in Fig. 1 but including the prior art. feed circuit of Fig. 2 (not shown). In an alternative embodiment Fig. 5 (not shown) a decoup-  ling diode (29) is connected between the thyristor cathode and that of Zener diode 16 and acts so  that the potential of the reservoir capacitor 18 is no longer affected by the triggering transistor 24 when it conducts so that the potential supplied to the oscillator 10 and stage 11 is sufficient even for voltages at pole 22 as low as 40 volts. In a third embodiment Fig. 6 (not shown) the voltage supply to the oscillator 10 and stage 11 is taken across a further Zener diode (30). In a fourth embodiment Fig. 7 (not shown) both gate and cathode of the thyristor 12 are triggered.

IPC: B60G11/04
Filed: 1926-02-04
Abstract: 256,128. Hounsfield, L. H. Feb. 4, 1926. Springs, arrangement of. -A spring suspension for vehicles comprises a normal spring 1 in which the de. flection is approximately proportional to the load, and a second spring 4 so controlled that the normal spring is deflected over an initial range of light loads without stressing the second spring, further deflection producing successively decreasing increments in the deflection of the second spring 4 for successive equal increments of load. As shown in Figs. 1 and 2, the normal spring 1 is of the full or semi-cantilever type connected to the axle 2, the second spring 4 being a plate spring pivoted to a fixed abutment 6 on the frame of the vehicle and connected by a link 3 to the axle. The system is deflected from the position shown in Fig. 1 to that shown in Fig. 2 without stressing the spring 4. Subsequently the spring 4 engages the abutment 6 and its effective length is decreased with increase of load. The arrangement is preferably such that the spring 1 is stressed to the safety limit when the spring 4 is in contact with the abutment over its entire length. The spring 4 may be arranged beneath the spring 1 which, as shown in Fig. 6, may be connected to the axle by a strap 7 which is slack during the initial range of light loading. The spring 4 preferably comprises a plate or plates of uniform section and radius of curvature.

Filed: 1965-01-26
Abstract: 1,054,702. Reactors. SOC. ANON. ANGLOBELGE VULCAIN. Jan. 26, 1965 [Feb. 7, 1964], No. 3318/65. Heading G6C. A baffle for surrounding the core of a liquidmoderated nuclear reactor is formed of several elements of corrosion-resistant material, e.g. zirconium alloy, the edges of the elements being bent to form ribs which serve both for the joining of the elements to one another and for increasing the rigidity of the baffle sufficiently to prevent its distortion by the differences of pressure to which it is subjected. In one embodiment (Fig. 4, not shown), the reactor core is of hexagonal cross-section and the baffle consists of an assembly of six prefabricated portions 11 which correspond to the six sides of the core. Each portion 11 is formed of five V-shaped elements 12, the faces 13 and 14 of which are bent so as to form between them angles of 120 degrees (Fig. 5, not shown). The elements 12 are assembled by welding of their faces 14 so as to form reinforcing ridges. The corners of the portions 11 are formed from profiled elements 15, which may be thicker than the elements 12 so as to reinforce the baffle. The portions 11 are fixed at each end to segments 16 which on assembly form flanges 17 around the baffle. The segments 16 are provided with oval openings 18 to receive keys by which the baffle can be mounted in the reactor structure whilst permitting thermal expansion of the baffle. In order to increase the rigidity of the baffle, circular bands 19 are mounted around its periphery, and the rigidity may be further increased by bending over the edges of the bands 19 to form beads 20. In an alternative embodiment, the baffle which is particularly adapted to be assembled around a core having a corrugated surface, is formed from elements which are not all of identical profile. By means of the elements of this invention, it is possible to reduce the thickness of the baffle to about 2 mm., a thickness of 6 mm. being necessary for the same rigidity in the case of a baffle without reinforcing ridges. The reinforcing ridges may form cavities with the rings 19 which become filled with liquid if a liquid reflector is used, thus increasing the thermal insulation between the core and the reflector.

Abstract: 575,052. Wedges. TRUSSED CONCRETE STEEL CO., Ltd., and GREEN, D. H. Feb. 23, 1944, No. 3403. [Class 89 (ii)] Wedge devices for fastening two elements together include two elongated co-operating members of which at least one is provided with a row of wedging surfaces to co-operate with abutment surfaces formed on or carried by the other, one of the members being capable of being driven relatively to the other. The device is particularly suitable for use in connection with shuttering for concrete. A pair of opposed plates 8, Fig. 8, each have near each edge a flange 10 with a perpendicular edge facing a flange 11 on the edge. In the channels thus formed plates 9, to form the shuttering for a concrete column are located and are clamped by pairs of bars 1 having co-operating wedge surfaces 2. The surfaces may be obliquely formed as at 4, Fig. 4, so that the engaged bars may be locked against relative lateral movement. In a modification rectangular wedge faces have part inclined longitudinally and the remainder obliquely. When oblique wedges are employed the flange 11 has an inturned edge 14, Fig. 9, to resist the lateral thrust. Applications to shuttering to form two parallel walls are illustrated, and in one form wedge surfaces on one bar co-operate with switches in a series of transverse bars that act as abutments.
