Title: Improvements in or relating to limiter circuits
IPC: H03D13/00
Filed: 1959-07-29
Abstract: 884,860. Flight simulators. ACF INDUSTRIES Inc. July 29, 1959 [July 29, 1958], No. 25982/59. Class 4. [Also in Group XL(c)] The Specification describes that part of an aircraft trainer which simulates the control of the " flaps " and the invention resides in an electrical network which simulates the condition where a hydraulic control system provides insufficient pressure to move the flaps to the desired position against the air resistance at high speed and low altitude. In the Figure, a control wheel controls differentially the position of the flaps while a speed brake handle controls them simultaneously, these two controls providing corresponding AC voltages at the input of an amplifier 38 of a servo control system. The output of the amplifier passes through a switch 46. which may be operated to represent switching the control into action, through a unit 50 and a further amplifier 12 to control a motor 10. The motor adjusts the position of a flap control shaft 16 to which a first potentiometer 28 is coupled to provide the feedback voltage for the servo system. A further potentiometer 26, also coupled to the shaft, feeds to amplifier 12 AC voltages representing the altitude and mach number of the aircraft. The network 50 limits the amplitude of the control voltage applied to amplifier 12 to a predetermined maximum value and may also prevent operation by voltages of the opposite phase. It thus simulates the condition in which there is insufficient power to move the flaps to the desired position. Specication 884,859 is referred to.

Abstract: 1,062,213. Tuning arrangements; self-oscillating mixers. STANDARD KOLLSMAN INDUSTRIES Inc. July 1, 1963, No. 26029/63. Headings H3F and H3Q. [Also in Division H1] A tuner comprises a plurality of air-cored coils tuned by metallic slugs axially movable therethrough to give a logarithmic change of frequency with respect to linear axial displacement, all the slugs being mounted on a single shaft. In Fig. 2, the coils 180, 181 are in the R.F. and oscillator circuits of an F.M. tuner and are traversed by nuts 190, 191 of non- magnetic metal (e.g. brass, aluminium) whose initial positions are adjusted for correct tracking and then secured by adhesive. The nuts are mounted on a threaded rod 179 of dielectric material journalled in a threaded boss 195 in the frame of the tuner. The end of the rod has a slot 203 which is engaged by the extension 202 of a tuning shaft 200 so that rotation of the latter produces axial movement of the nuts Movement of the shaft is limited by a Geneva cross mechanism 205, 206 (details in Fig. 8, not shown) which has one segment larger than the others to permit only four revolutions of the shaft 200. Self-oscillating mixers (Fig. 1, not shown).- The circuit is given of an R.F. and mixer stage using the tuning arrangement of Fig. 2. The two halves of a double triode are used respectively as grounded-grid R.F. amplifier and selfoscillating mixer, with tapped-capacitance oscillator circuit to minimize radiation at oscillator frequency. An A.F.C. voltage is applied via a silicon junction variable capacitance diode. The mixer-oscillator valve may be a pentode.

Title: Means and Method for Controlling the Output Granulometry of Grinders and Crushers.
Inventor: BARROT PAUL MARCEL EMILE
IPC: G05D5/06
Filed: 1968-05-31
Abstract: 1,185,447. Gyratory crushers. SOC. ANON. DITE BABBITLESS. 31 May, 1968 [31 May, 1967], No. 26242/68. Heading B2A. [Also in Division G3] The inner crushing cone of a conventional gyratory crusher is automatically controlled to maintain a predetermined particle size distribution in the crusher output. The method of control (see Division G2-G3) involves the measurement of various outputs of the crusher by a screen, weighers and conveyor belts, Figs. 2, 3 and 4 (not shown) and the detection of the axial position of the inner cone 17 by the arrangement shown in Fig. 5. The shaft 19 of this cone turns inside a collar 20 fixed in respect of rotation by flexible parts (not shown which absorb the eccentric displacements of the shaft. Axial displacement of the shaft 19 is detected by a fork 15 engaging a ball or cylinder 22 at the end of a feeler 21 secured to the collar 20. Fork 15 is connected to a second feeler 23 freely slidable in a cylinder 24 and carrying a finger 23a engaging a link of an endless chain 26 passing over three cogged wheels, Fig. 6 (not shown). A contactor 16 turns with one of these wheels and, by means of its electrical connections with other multi-contact ganged switches in the automatic control system, Fig. 7a (not shown), effects the recording and control of the movements of the inner cone. These movements'are effected by a motor/pump unit and valves which respectively supply fluid to or withdraw it from the suspension actuator of the inner cone. A protection arrangement automatically takes control to open the valves and prevent operation of the pump unit should the fluid pressure in the suspension actuator exceed a predetermined value. The protection arrangement automatically returns the inner cone to its position existing before the overload and automatically interrupts the power supply to the pump and valves should more than a predetermined number of successive overloads occur. There is also described, Fig. 8 (not shown) a manual control for adjusting the position of the inner cone having a collar and feeler arrangement generally similar to that of Fig. 5, the second feeler co-operating with a switch housed in a casing which is manually adjustable relative to the frame of the crusher.

Filed: 1945-10-11
Abstract: An insecticidal, fungicidal or herbicidal powder for application to plants is prepared by generating an electric field, and passing a suspension in air of the powder through the electric field.  Thus the powder in air suspension may be passed in the vicinity of a high-voltage electrode charged to about 20,000 volts which may be situated in the neighbourhood of or beyond the outlet aperture of the apparatus.  Ionisation may be increased by coating the electrode with a radioactive substance such as thorium oxide or by submitting it to short wave radiation.  The electrode may be one or more straight electrified wires pointed if desired or a vibrating electrified metal plate upon which the powder is distributed from a hopper. Alternatively, the powder suspension may be electrified by friction, e.g. by being blown tangentially into the base of a truncated conical chamber made of "Bakelite" (Registered Trade Mark) of which the small open base serves as the nozzle.  Triangular metal blades may be secured to the wall of the chamber to eliminate electricity of opposite charge which tends to accumulate thereon.

Title: Improvements in or relating to walking toys and to games in which they are utilised
IPC: A63F9/14
Filed: 1947-10-02
Abstract: 643,744. Walking toys; race games. TETT, H. L. Oct. 2, 1947, No. 26591. [Classes 132 (ii) and 132 (iii)] In a walking toy which can be made to rock in alternate succession on two pivots provided by the ends of two downwardly projecting limbs arranged fore and aft of the toy, the forward limb is flexible so that as a consequence of a forward rocking movement the forward limb is flexed and thereby shortened, and the near limb is drawn forward to cause the toy to advance. As shown the toy consists of a jockey-mounted horse 10 which moves along a rail 12 on which it is supported by a U-shaped support 14. One limb 22 of the support is fixed to the back legs of the horse, the forward limb 20 being relatively flexible. An arm 16 depends from the horse and carries a weight 18 at its lower end, so that the model comprises a pendulum which may be made to rock about the end of one or other of the two limbs 20, 22. The horse may be caused to progress along the rail by pulling on the string 24 attached to the weight 18, causing the figure to rock about the end of limb 20 which limb is flexed and shortened, drawing limb 22 closer to it in consequence, Fig. 2. When the string is released, the direction of rocking is reversed by the weight, the horse turning about limb 22, limb 20 straightening out and moving forward. If desired, certain parts of the toy such as the jockey's arms and the horse's head may be made relatively movable to the body. A race game may be played with a number of horses, the track being slotted to accommodate the weighted arm. The horses may be advanced by any rocking means such as by impulses given by means of a whip. The toy may take other forms, for instance a racing greyhound or other animate or inanimate object.
