Title: Improvements in or relating to a method of securing an insert in sheet material
Inventor: PRESTIGE HARRY THOMAS
IPC: F16B37/06
Filed: 1960-10-21
Abstract: 912,516. Punching; riveted joints; assembling force-fits. BELLING & LEE Ltd. July 14, 1961 [Oct. 21, 1960], No. 36119/60. Class 83 (4). A method of securing an insert in a sheet of material comprises using the insert as a punch in conjunction with a die, the cutting edge of which has substantially the same contour as the leading face of the insert and is characterized in that the leading face of the insert has a larger cross-section dimension than the following part thereof and the face of the die is formed so as to force an annulus of material around the following part and behind said leading face, thereby to assist in anchoring the insert in the sheet material, the part of the insert at the end of the following part opposite said leading face being so formed as to coact with said die in assisting the formation of said annulus. In an embodiment, a sheet 1 of resin-bonded paper laminate is placed on a sheet of aluminium 2 which stands on a die 3. The top face 5 of the die has a projecting annular ring 6 which has a chamfer 8 and a flat top 9. An aluminium rivet 10 has a leading face 11, a reduced middle section 13 and a head 15. When the rivet is acted on by a ram 17, the shape of the rivet head and the presence of the ring 6 cause an annulus 18 of material from the sheet 2 to be forced against a chamfer 14 on the rivet, and as the rivet head penetrates the upper sheet 1 an annulus of material 19 is formed round the rivet. Specification 776,373 is referred to.

Title: Improvements in or relating to aircraft
IPC: B64C13/46
Filed: 1954-12-15
Abstract: 794,505. Fluid-pressure servomotor-control systems. HOBSON Ltd., H. M., and WESTBURY, R. Nov. 11, 1955 [Dec. 15, 1954], No. 36352/54. Class 135. [Also in Group XXXIII] An aircraft control system in which the pilot's control member is coupled to the input member of a servomotor actuating a control surface, comprises a device for imposing on the input member a feel force proportional to the velocity of displacement of the control surface and to a function of airspeed which increases with airspeed. In Fig. 3 the surface is actuated by an hydraulic jack of which the piston-rod 16 is anchored at 17, and the cylinder 15 is linked to the control surface by a link 21. A bracket in the jack pivots a bell-crank lever 22, one arm being connected to the pilot's control member (not shown) by a link 11, and to the control valve 18, and the other arm to the piston-rod 25 of a piston 26 in a cylinder 27 pivoted to the jack. The valve 18 co-operates with fluid pressure inlets 19 and an exhaust port 20. The piston 26 is subjected to a control pressure derived from a unit (not shown) as described in Specifications 734,437 or 740,510, [Group XXXIII]. This pressure is caused to increase or decrease with airspeed, and the relationship may be modified above a given airspeed or Mach number. When the pilot displaces the control member, the valve 18 is displaced relatively to the jack body, and is subjected to a centring force from piston 26. This force is proportional to the pressure in cylinder 27, and also to the displacement of the bell-crank lever, i.e. the displacement of valve 18. From the characteristics of the servomotor, the velocity of the control surface is proportional to the displacement of valve 18, whence the centering force is proportional to the velocity of the control surface. A bob weight may be connected to act on the pilot's control member, being responsive to normal acceleration in the case of elevator control, and to acceleration in roll in the case of ailerons.

Abstract: 370,442. Controlling variable-speed gearing. IMPROVED GEARS, Ltd. and WILSON, A. G., 23, Queen Anne's Gate, London. Dec. 8, 1930, No. 37019. [Class 80 (ii).] Relates to change-speed epicyclic gearing in which a speed is brought into action by the application of a preselected brake by a spring- actuated bus-bar e, Fig. 3, which is rocked about a knife-edge e<1> by a pedal against the spring to disconnect the drive, as described in Specification 328,660, [Class 80 (ii), Gearing, Variable-speed &c.]. According to this invention, cam selector and other mechanism shown in Fig. 4 is supported upon a cover-plate p detachable from the gear casing A. Selection is effected from the steering column of a vehicle by operating a lever s, Fig. 3, supported by the plate p and geared to turn a shaft f carrying spaced cams g, Fig. 4, in different phases. The cams g are shaped to allow one only of a number of levers k to be advanced by its spring v so as to thrust a selected strut d into the path of the bus-bar e as it rises on release of the said control pedal. There is a brake band a, Fig. 3, and a toggle actuation for each of the brake drums B of the epicyclic gearing, not shown. As the selected strut d rises, it turns a lever b tightening the selected band a. An interlock to allow one only of the struts d to be raised is also supported on the cover-plate p. This comprises pivoted blocks m suspended side by side between two fixed stops m<2>, Fig. 4. As a strut d is raised by the bar e, a snug n on the strut is guided by inclines m<3> in between a pair of blocks m. The other blocks m move so as to fill the whole of the space between the stops m<2>, and so prevent the entry of another snug on another strut.

The device 25 rotates about the axis of the drum 15. Fig. 1 shows the storage device in a draw bench for billets. A billet 2 from a coil 1 passes through a butt welding machine 3, is wound several times around the larger drum 15 of the storage device 4, and is then passed through the device 25 of Fig. 4 before being wound around the smaller drum 13 of the storage device 4. Thereafter the billet passes through tension control means 5, a billetpusher 6, a die 8 and a draw block 9 from which coils of the billet are deposited in a container 11. When the coil 1 is empty a brake 26, Fig. 3, is applied to the larger drum 15 to stop its rotation. A member 17 carrying the axis 18 of the smaller drum 13 is then caused, by drive means 22, 23, to rotate in a direction opposite to that in which the larger drum 15 was running. Owing to the difference in diameters of the drums 13 and 15 each revolution of the member 17 results in turns on the drum 15 being transferred to the drum 13 so that the drawing process through the die 8 can continue. In the mean time a billet end from a further coil 1, adjacent to the coil 1 shown in Fig. 1, is guided to the welding machine 3 and is butt-welded to the now stationary end of the previous billet length. When the butt weld has been completed the brake 26 acting on drum 15 is released and the direction of rotation of the member 17 is reversed by reversing the direction of rotation of the motor 22. This causes the extra turns accumulated on the smaller drum 13  to be used up by the drawing process and for turns to be accumulated on the larger drum 15 to make up for the turns unreeled from that drum during the butt-welding operation. As soon as all the turns collected on the smaller drum 13 during the abutting operation have been removed, the member 17 is braked and the drums 13, 15 continue to run freely about their spindles and the turns on each drum then remain constant.

Abstract: 1,168,104. Programmed control of machine tools. GIDDINGS & LEWIS Inc. Aug.14, 1967 [Aug. 17, 1966], No.37216/67. Heading G3N. A data processing system supplies electrical signals, indicative of a plurality of different types of data recorded in blocks on a record medium, to a data processing apparatus for the simultaneous control of a plurality of utilization devices, corresponding in number to the types of data, by generating control signals distinctive of the type of data demanded and transferring to the data processing apparatus from a reader when output signals indicative of the types of data co-exist with the distinctive control signal. As shown, a tape reader 34 reads and signals the identity of data represented by successive portions of tape and feeds signals through a decoder 35 to temporary storage registers 36. The data is subsequently transferred by gates 38 into active storage registers 39 for a contouring interpolator 40 deriving command pulses for the X and Y co-ordinate movements of two machining heads 14, 26. The axial positioning arrangements for the axes heads are conventional and comprise, for the X axis of head 14, a digital to analogue converter 41AX and an error discriminator 42AX, to which a positional feedback is applied from a transducer 45AX, controlling a servo-amplifier 44AX energizing a motor AXm. A signal indicative of the completion of an incremental movement called for by a block on the tape is provided by AND gate 50A or 50B. For the head 14, AX, AY command pulses are fed to counters 48AX, 48AY and compared with the corresponding movement values stored in registers 39 in comparators 49AX, 49AY which produce output signals when these numbers are equal. These signals terminate the AX, AY command pulses until fresh head 14 data is fed into register 39 and, when both output signals are present at gate 50A, cause a signal AEPC to be fed to a tape reader search control 51. Similarly B head signals BEPC are fed from gate 50B and signals ZFRA, ZFRB are also fed to the control 51 from the director 40 when either head is at rest. The tape reader search control 51 effects the dumping of fresh head data from the temporary registers 36 through transfer gates 38 to the storage registers 39 and in turn causes the tape reader 34 to be rendered operative and read a new block of head data into the temporary registers. The search control 51 cause forward or reverse movement of the tape in the reader 34 and 'hunts' through the tape to find the required data, returns the tape to the first unused block of data and limits 'hunting' at special reco-ordination points (P code) or mandatory stops (E code).

A plurality of magnetic reeds la, 1b, 1c, 1d, 1e, 1f are mounted in an insulating resilient block 2 which envelopes the reeds to differing extents so as to impart different stiffnesses to the reeds and to mechanically couple them together. Two of the above sets of reeds are mounted in a common envelope with their contacts overlapping. The air gap between co-operating pairs of reeds progressively increases from the most flexible pair, e.g. 1a to the stiffest pair, e.g. 1f. When a common flux is applied to the reeds, the pair la being closest together close first, shunting some of the flux so that there is insufficient flux to close the adjacent pair 1b. However, closure of pair 1a causes flexure of the resilient blocks, e.g. 2, and the combined mechanical force transmitted by the block and electromagnetic flux is sufficient to close pair 1b. In this way, the pairs of reed are closed in succession. Although the block is of stepped form as shown, it may be triangular. The gaps between co-operating reeds may be the same. The contact arrangement may be utilized in a remanent relay of the type described in Specification 870,906 or may be surrounded by an energizing coil.
