Title: Improvements in or relating to the manufacture of forks for agricultural, horticultural and like purposes
Inventor: MILLS EMUND HARRY
IPC: A01B1/04
Filed: 1963-12-31
Abstract: 1,048,040. Making pronged implements; altering physical properties. WILLIAMS MILLS & CO. (SHEFFIELD) Ltd. Dec. 14, 1964 [Dee. 31, 1963], No. 51262/63. Headings B3A and B3V. In a method of manufacturing a multipronged fork or the like a blank is produced having the prongs at least in pairs in integral mass formation (Fig. 2, not shown). The prong formations are rolled to produce the required dimensional taper and the individual prongs are formed in a further blanking step. The socket is formed after the initial blanking step and the blank is reheated between each step outlined above. Hence only three reheats are required and so the method is particularly suitable for working stainless steel, which is worked at 900-1000‹ C., the temperature. falling to not less than 750‹ C. between each operation. When making large agricultural forks, the outer prongs may be bent to the required shape after the further blanking step (Fig. 8, not shown)

IPC: B01F11/02
Abstract: 516,341. Making dispersions. HARDIE, H. April 23, 1938, No. 12219. [Class 1 (i)] An apparatus for making dispersions comprises a container 15 in which a number of impacting elements 31 are mounted in axial alignment on a member 34 so as to divide the container into a number of substantially separate juxtaposed volumes, the elements being adapted to give rapidly recurring disruptive impacts to the liquid in the container. The elements 31 may be perforated. The container may be oscillated and/or rotated, e.g., by means of teeth 60 which mesh with a non-circular gear wheel 81 driven by a motor 64. A reciprocating motion is given to the impacting elements by an electromagnet 91 attracting an armature 90 against a spring 92. The treatment may be effected at increased or decreased temperature.

Title: Notch rejection filter circuit
IPC: H04N7/16
Filed: 1974-12-03
Abstract: 1490225 Filter networks RCA CORPORATION 3 Dec 1974 [13 Dec 1973] 52203/74 Heading H3U A tuned filter circuit for blocking applied signals of a given frequency includes means for continuously varying the tuned frequency of the filter over a range which includes the given frequency, so as to ensure blocking in the event of random drift. The tuned frequency is varied by applying an alternating voltage to a varactor diode in the circuit. As shown, the filter comprises an inductor 10, fixed capacitors 12, 14, and a variable capacitor 18 which is adjusted so as to block an incoming television signal at a terminal 20. A coder 26, in the form of a normally open switch, is operable by a signal e.g. from a computer, to connect a further capacitor 24 in circuit, so as to shift the tuned frequency of the filter and allow the input signal to pass to an output terminal 22 which may be connected to a pay television receiver. Rectifiers 28, 30 connected across the capacitors 12, 14 exhibit cyclically varying capacitances dependent on an oscillating voltage supplied from a source 34, so that the blocking frequency of the filter is continuously varied over a frequency range which includes the frequency of the input signal when the capacitor 24 is not in circuit. In this way, even if the tuned frequency of the basic circuit drifts from the required value, the filter will block the incoming signal for at least part of the time during cycles of the voltage source 34.

Filed: 1972-11-15
Abstract: 1457404 Pneumatic tyre and wheel rim assemblies DUNLOP Ltd 13 Nov 1973 [15 Nov 1972] 52658/72 Heading B7C A pneumatic tyre and wheel rim assembly includes a pump which is operable by the tyre, when running deflated, to supply inflation air into the tye cavity and a lubricating material for facilitating relative movement between contacting regions of the interior surface of the tyre when the latter is running deflated. As illustrated, the pump comprises two telescoping cylinders 11, 12 which receive atmospheric air via a non-return valve (not shown) in orifice 9 when cylinder 12 moves radially outwardly under centrifugal force and spring 13 (if present). When the cylinder 12 is forced radially inwardly by the tread of the deflated tyre the air contained by the cylinders is forced via a one-way valve (not shown) into the tyre cavity. The tyre is non-demountably mounted on the rim which (as shown) can be a flat-based, split rim. Also, as shown, the extension of toe 6 of bead 7 into notch 5 prevents the bead 7 moving axially inwardly of the rim. Alternative arrangements for mounting the tyre non-demountably include a bead spacer ring or removable bead retaining studs. The lubricating material may contain a puncture sealing material. If only one pump is provided a counterbalancing weight will be provided. Alternatively the assembly may include a plurality of pumps. The inlet valve or a pump may be combined with the inflation valve of the assembly so that the assembly is inflated via the pump.

Abstract: 1403597 Vehicle collision sensors; safety devices NISSAN MOTOR CO Ltd 24 Nov 1972 [30 Nov 1971 28 April 1972] 54319/72 Headings B7B and B7H A motor vehicle collision sensor comprises a housing 52 having an elongate actuating member 58 slidable in a bore 56 therein and biased into a position extending externally of the housing, the actuating member 58 being arranged to be retracted into the housing upon a collision to actuate a safety device switch means. In a preferred embodiment, Fig. 1, a bumper 10 has a back plate 15 for securing a plate 31 of a piston-rod 25 movable within a shock absorbing cylinder 23 secured on the vehicle chassis. A resilient member 35, Fig. 2, of foam rubber is interposed between plates 31 and 15 and arranged to provide slight relative lateral movement of the plates 31, 15. The sensor 50 is mounted on the plate 31 and the actuating member 58 extends through apertures 76, 75 of the piston plate 31 and resilient member 35 respectively leaving a gap between the tip of the actuating member 58 and the back plate 15. On a collision the bumper 10 compresses resilient member 35 and member 58 is urged into the housing 52, Fig. 3, against spring 67 to disconnect contacts 62, 63 resulting in actuation of the vehicle safety device. Other embodiments are described in which the switch means comprises an electrically conductive leaf spring (85), Fig. 4 (not shown), which breaks a contact. In Fig. 5, switch means comprising two contacts (108), (110), Fig. 6 (not shown), one of which is magnetic, are hermetically sealed in a tube 92 which may contain inert gas or be evacuated, and are actuated by a permanent magnet 90 mounted on the actuating member 100. A cover (120), Fig. 7 (not shown), may enclose the actuating member 58. In another form of switch means, Fig. 8, the actuating member 138 is urged into housing 130 and piston 136 causes bellows 142 to expand pneumatically to move plate 144 away from fixed contact 152 against action of spring 146. In another switch means, Fig. 9 (not shown), the biasing means comprises a permanent or electromagnet (160). Fig. 10 illustrates a switch means comprising a tubular contact member 165 which shatters upon a collision from the end plate 60. The contact member may be glass coated with an electrically conductive material, or may be formed of carbon. A sensor 50 may be connected in series with an inertia switch (170), Fig. 13 (not shown). As shown in Fig. 14, the sensor 50 is opened upon a collision thus reducing to zero the force on weight 174 by electromagnet 182, so that weight 174 moves into contact with fixed contact 186. In another arrangement of inertia switch, Fig. 15, provision of electromagnet 206 connected in series with collision sensor 50 serves to reduce the magnitude of deceleration above which the inertia switch 170<SP>1</SP> is actuated at the time of collision.
