IPC: G09B9/46
Abstract: 1,047,365. Grounded flight trainers. COMMUNICATIONS PATENTS Ltd. May 3, 1965, No. 18561/65. Heading B7W. [Also in Division G4] A ground-based helicopter flight simulator includes means for computing the Mach number of a rotor blade element in forward flight. The simulator uses the following formula which gives the square of the maximum blade tip Mach number and uses it to modify the rotor drag and thrust coefficients used in the simulator: where K is a constant, T the ambient temperature, # the rotor angular velocity, R the radius of the rotor, U the helicopter forward speed, and Áx the ratio U/#R. A summing amplifier has inputs corresponding to U<SP>2</SP>; #<SP>2</SP>R<SP>1</SP> derived from a signal corresponding to R<SP>2</SP> modified by a rotary potentiometer whose shaft position corresponds to #<SP>2</SP>; 2#<SP>2</SP>R<SP>2</SP>Áx, derived from the signal #<SP>2</SP>R<SP>2</SP> modified by a rotary potentiometer whose shaft position corresponds to Áx; and a feedback signal from the amplifier modified by a rotary non-linear potentiometer whose shaft position corresponds to T. The output (- M<SP>2</SP>) is applied to two networks having non-linear outputs representing rotor thrust and drag coefficients respectively, each (Fig. 3, not shown), having a negative input (- M<SP>2</SP>) and a fixed positive input connected by three circuit elements in parallel, each circuit element comprising two resistors in series, such as 40, 43, a point 49 between them being connected to summing through a diode which passes current when the point is negative. The resistors of the elements are arranged so that the points 49, 50, 51 become negative at different negative values of (- M<SP>2</SP>) and thus the output of the network is not linear with M<SP>2</SP>.

A mill comprises a cylindrical housing 1 provided with air admission openings 10, the housing having a partition 3 provided with openings 11 co-operable with openings 12 in a rotatable plate, the housing containing a rotary drum 15 having a paraboloid wall 18 and being partly filled with a heavy liquid, e.g. mercury, for balancing purposes, the outer surface of the drum having inclined impeller paddles 16 for drawing air through the openings 10, 11 and 12, the housing having secured thereto a ring 20 to which is fastened, by bolts 21, a cover 22 provided with ridges 23, the housing being surrounded by a discharge hopper 24 having an outlet duct 25, and the cover 22 having secured thereto an inlet duct 27. Plate with the openings 12 has a rack engaged by a manually-operable gear 13. In operation, material fed through duct 27 falls by gravity on to wall 18 until the latter is covered by a predetermined thickness of material. Further material falling by gravity on the material on wall 18 is thrown upwardly against the ridges 23 and at the same time strikes descending material. If a fine dust is desired, the gap between members 20 and 22 is completely closed and the air flow drives the dust through duct 26. When coarser particles are desired, the members 20 and 22 are separated to provide a suitable gap and ground material leaves the mill by centrifugal force through the gap between the members 20 and 22 falling into hopper 24 to be discharged through duct 25.

Abstract: 1,054,871. Packaging-machines; conveyers. B. C. EISENBERG. Jan. 3, 1964, No. 340/64. Headings B8A and B8C. Apparatus for packaging articles such as string beans in cans comprises means to feed the can along a path while subjecting it to a centrifugal acceleration directed towards its base so as to urge the contents towards the can bottom. As described, the can is oscillated about an axis parallel to its path and above its mouth. ' The beans are fed into a rotating drum 22 from a channel 36 and are untangled and carried towards the drum top by lines of tines 37b. The drum is of perforate material to permit escape of moisture. The beans then fall into a vibrating shoot 38 which guides them into a line of cans 11 being advanced on a conveyer 15. The conveyer consists of a series of cylindrical links with flexible joints 15a, Fig. 5 (not shown), running in a semicircular channelled bed 16, 19. The cans are located by guide rails 46 attached to yokes 48 pivoting on a shaft 49. The yokes are oscillated by the shoot vibrator 41, thus swinging the cans and urging down the beans. The conveyer itself may be vibrated, such as by means 18 (not detailed). In a further embodiment, Figs. 6-9 (not shown), the cans pass between four rails 72, the upper of which have diverging plates 89 for funnelling beans to the cans. The rails are attached to yokes 74, 75 oscillated by cams 81 outside the drum. The inner surface of the drum may have a helical strip acting as a screw feeder to move beans towards the shoot 85 which extends only part way along the drum's length. To remove excess beans from the container, a rotating arm 90, Fig. 6 (not shown), may sweep off all those extending above the top and a resiliently mounted plate 96a or a roller (not detailed), apply pressure to the container rim to cut off beans hanging over the edge.

In one form, heating (or cooling) pipes 42 are mounted in a frame 53 hinged at 54 to a frame 52 fixed to the wall, insulating material 22, which may be a foamed plastic, being located between the pipes and the wall. This form enables the frame 53 to be swung clear of the wall for cleaning. Flexible ducts connect the pipes to supply and return lines. In another similar form the pipes may be wound in coils around the window or door opening (Fig. 17, not shown) and may be of soft annealed copper or of a plastic. Other alternatives include one or more rectangular pipes (Figs. 2 and 11), several passages of tapered cross-section (Fig. 10), several spaced tubes with openings (47, Fig. 12) in the vertical walls to allow for convection, and a number of separate pipes each making a single coil round the window opening and being connected to supply and return lines (Fig. 18).

In a circuit converting a first binary code represented by a positive followed by a negative potential and a negative followed by a positive potential into a second binary code form represented by positive and negative potentials, each incoming first code element is sampled during its first portion and stoved temporarily in analogue form then compared in a comparator with the second portion to determine the significance of the element. The comparator is only effective during the second portion. An incoming signal IP is amplified and fed to a capacitor through a sampling gate SG enabled by sampling pulses tl, see Fig. 1 (not shown) the capacitor voltage being compared in a comparator COMP with the signal during second sampling periods t2. The output of the comparator displaces a JK flip flop to a corresponding 1 or 0 condition. The sampling gate comprises cascaded transistors (T1, T2) Fig. 3 (not shown) which are rendered conductive by t1 pulses; hence a capacitor C charges through another transistor (t3) if the pulse on T2 is higher than the capacitor charge, or C discharges through a diode D if the pulse on T2 is lower.

The strip is rolled so that its ends abut and is press fitted into a cyanide hardened mild steel cup 18 secured to an arbor 16. The press fitting causes the cup and strip to flare outwardly slightly so that the cylindrical shape is slightly tapered to provide a clearance when cutting. Prior to fitting in the cup, the teeth are cut by a punch and die 46, 48, Fig. 8, the punch moving outerwardly. Every other tooth over less than half the circumference is set inwardly by a tool 83. The teeth are ground to have an inclined cutting edge by a grinding wheel 52, Fig. 11, the saw is provided with a piercing tool 36, a drill or a tapered centring tool which may be formed with an enlarged part to assist in removing the cut piece of a workpiece from within the tool.

In an alternative embodiment, a sponge 124, Fig. 17, is retained within the blade by a plate 126 supported by rods 128. In use, the sponge is saturated with lubricant and compressed as the saw into the workpiece. The lower edge of the cup may be serrated to effect clearing of the surface adjacent the edge of the cut hole or be chamfered so as not to damage the surface.
