Filed: 1943-07-27
Abstract: 567,254. Cooking stoves. STOVES, Ltd., and RYDER, S. E. A. July 27, 1943, No. 12171. [Class 126] In a cooking stove including a griller in addition to one or more cooking devices, the overall height of the stove is reduced by arranging the griller at an angle to the horizontal so that its heat is directed into the acuteangled space between itself and the horizontal. The invention is shown applied to a gas stove fitted with a boiling grid 2 and grilling device consisting of a burner tube 8, baffle plate 6 and radiant element 7, all mounted to rotate as a unit about the axis of the gas-pipe supplying the burner 8. The griller is supported by a stud spindle 13, Fig. 4, engaging in a socket 14 in the side wall of a drip tray 15 and is retained in the inclined position by a flat 17 bearing on a step 16. By axially withdrawing the burner tube 8 by means of the handle 18, the flat 17 moves out of engagement with the step 16 and the complete griller may be turned down into the horizontal position to serve as a hot-plate. The food to be grilled is supported on a wire grid 19 hinged to a frame 20 and adapted to be held at an inclination slightly greater than that of the grill 7 by a hinged strut 21.

Abstract: 1458259 Electrolytic production of ultra-thin copper foil YATES INDUSTRIES Inc 19 March 1974 [3 Dec 1973] 12175/74 Heading C7B A composite foil consisting of a copper support layer and a copper layer of a thickness which is not self-supporting is formed by electrolytic production of a self-supporting copper foil and the electrodeposition of further copper on to said foil, e.g. from a CuSO 4  bath, to form a layer of non-selfsupporting thickness, the deposition of said layer being preceded by application of a thin layer of a release agent which permits electro-deposition of copper thereon and will permit release of a non- self-supporting layer of copper deposited thereon without tearing. The release agent may be a sulphide or chromate, e.g. electrolytically formed using a sodium sulphide or chromic acid bath, or oxide, or Pb, Ni, Ag or Cr (the Cr may be depassivated by phosphoric acid solution. Copper clad laminate may be formed by adhering the non- self-supporting layer to a substrate and peeling the initial supporting layer therefrom. Adhesion to the copper layer to the substrate may be improved by depositing a dendritic layer thereon, the combination still being of non-self-supporting thickness.

Title: Improvements in or relating to toy motor vehicles
IPC: A63H17/00
Filed: 1960-04-08
Abstract: 891,681. Toy vehicles. MECCANO Ltd. April 8, 1960 [Feb. 1, 1960], No. 12500/60. Class 132(3) The axle 4 for the front wheels of a toy motor vehicle is supported in slotted lugs 2, the slots each having a depression in which the axle is normally held in position by a blade spring 6 secured to the floor 1 of the vehicle. The spring has a hole to clear a spigot 8 by which the vehicle body (not shown) is mounted on the floor. Light downward pressure on one or other wing of the vehicle causes the axle first to assume the dotted line position, Fig. 1. The end of the axle at which the pressure is applied then moves rearwardly up the inclined portion of the slot. Correspondingly the other end of the axle moves forwardly along the horizontal portion of the slot in the lug on the other side of the floor and the axle pivots about lugs 9 which extend downwardly from the spring 6. With the downward pressure maintained on the vehicle, the axle remains pivoted and the vehicle follows an arcuate path. On removal of the pressure, the spring urges the axle into the depressions in the slots and the vehicle moves in a straight line. The spring may be slotted longitudinally from each end to provide individual spring limbs for the opposite ends of each of the axles. The lugs 9 may be replaced by lugs bent up from the floor or by spigots formed on a die cast floor. In a further modification, Fig. 6, the forwardly extending horizontal portions of the axle slots are omitted and the axle 4 rests against a rearwardly inclined single lug 12. The uppermost ends of the slots are formed with recesses tending to retain the axle ends in the upper positions when displaced by downward pressure on the vehicle body. A spigot or spigots may depend from the body of the vehicle to co-operate with the axle 4 in place of the lugs or spigots provided on the spring or floor.

Title: Improvements in or relating to gear cutting machines
IPC: B23F21/18
Filed: 1924-05-26
Abstract: 238,935. Saito, M. May 26, 1924. Gear-cutting; milling-cutters.- Bevel gears with curved teeth are cut by means of a taper or cylindrical hob of variable pitch, the curve of the hob teeth being such that the development on a plane surface may be expressed by the equation :-y = Ax<2> + Bx + C in the case of a cylindrical hob, or @ = A<1># + B' log p + C' in the case of a taper hob. Fig. 1 shows the relative positions of a hob 2 blank 3 and the imaginary crown wheel 1 which the hob represents. From the speed relations which must exist between the rotation of the blank and hob it is shown that the angular velocity v of the hob is given by v = - (V<1> - v<1>/sin@) where n = no. of threads on hob, N<1> = no. of teeth on blank, V<1 >= Angular velocity of blank on its axis, v' = Angular velocity of blank relative to hob about the axis 0, @ = cone angle. of the blank. In Fig. 3 the X axis is the trace of the plane containing the hob axis and perpendicular to the crown wheel plane, the line FG denoting a tooth on the crown wheel and 4 the developed tooth of a hob. FH being the common tangent. From the condition that this tangential relation must exist at all points along the hob it is shown that the equation of the line 4 is y = 1/2R x<2>- @N/Rnx, where R = length of line O E, r = radius of hob pitch cylinder. The Specification also describes the cutting of gears by means of a cutter having a conical pitch surface, and it is shown that in this case the developed curve of the hob teeth may be expressed by the equation @ = A<1> @ + B<1> log p + C<1>. A machine for cutting gears according to this method is shown in Figs. 5 and 0. The hob spindle is mounted in a member 8 and can be secured in the desired angular position on a slide 9 which is rotated about the axis O O<1> to give the angular movement v<1> to the hob by means of a pinion 11 engaging a toothed sector and driven from the pulley 12 through shaft 18, reversing change gears 20, shaft 22, and worm gearing 21. The hob spindle is also driven from the pulley 12 through shafts 13, 14, differential gearing 25. shaft 15, reversing bevel gearing 27, and shaft 17. The planet member of the differential gear is driven from a shaft 23 which is connected by change gears to the shaft 22 to compensate for the rotarv movement of the tool head. The shaft 31 of the hob-driving train is connected by change-gears to a shaft 32 driving through the gearing shown in Fig. 5, a worm-wheel 39 on the spindle carrying the blank 3. The blank holder 37 is angularly adjustable about the axis O 0<1> so that the blank may be adjusted to a position corresponding with the central line O C<111> in Fig. 1. the teeth being completely formed by movement between the positions O C' and O C".

Abstract: 857,079. Machine tool details. CLIMAX ROCK DRILL & ENGINEERING Ltd., [formerly CLIMAX ROCK DRILL & ENGINEERING WORKS Ltd.] April 24, 1958 [April 23, 1957], No. 12943/57. Class 83 (3). [Also in Group XXIII] A pneumatically-fed drill is controlled by a dashpot so that while the drill is away from the workpiece a by-pass is exposed between the dashpot spindle and a sleeve, allowing rapid movement of the drill towards and away from the work, and, when the drill engages the workpiece the passage is closed and liquid in the dashpot has to pass through a restriction, the relative movement between the piston and the spindle causing relative movement of parts which engage a rod lying parallel to the drill axis and move the rod with the travelling assembly away from an abutment and against spring action to a position in which the movement is reversed, the rod being released from the engaging parts when the by-pass is opened. As shown, a drill 2 fixed to a rod 4 is fed by a pneumatic piston 6 mounted on a sleeve 8 surrounding the rod 4. A dashpot piston 10 having a by-pass is mounted on the sleeve, and controls the movement of the sleeve, the speed being regulated by a valve 12. When pneumatic pressure is applied to the piston 6 it moves forward together with the drill 2 until the drill bit engages the work when relative movement between the sleeve 6 and the rod 4 closes the by-pass and causes a wedge 16, Fig. 2, attached to a collar 18 on the sleeve to lock a collar 14 on the rod 4 to a rod 20 mounted parallel to the rod 4 and able to move longitudinally in bearings 22, 24. The piston then moves the rod 20 against a spring 28 until a flange 30 engages a micro-switch 32 which causes reversal of movement of the piston 6 and disengages the wedge, rearward movement of the rod and piston being stopped by the rod engaging a second micro-switch 34 which again causes reversal of movement of the piston.
