Patent GB-103686-A (GB)
Title: Improvements in Angle Trisecting and Bisecting Instruments.
Inventor: JOINER SEABORN MATHEWS
Filed: 1916-02-02
Abstract: 103,686. Joiner, S. M. Feb. 2, 1916. Dividing-instruments.-An instrument for trisecting, and optionally for bisecting, angles comprises a symmetrical quadrilateral frame of pivoted bars 2 - - 5 having trisecting-bars 12, 13 mounted on a pivot 6 on the axis of symmetry. The diverging ends of these bars are curved and slidably and pivotally connected with the two side members 4, 5 remote from the pivot 6 in such a way that they may be held in any adjusted position. As shown, the quadrilateral is equilateral. In order to set out the axial curve C at the free end of the bar 12, the frame is opened so that the bars 2, 3 enclose a right-angle, and set-screws 16 are so placed on the bars 4, 5 that this angle is trisected by the bars 12, 13, slots in which engage the set-screws 16. With centre 6 and radius 6, 7, a circle is described cutting the axis of symmetry at 9<a>. With centre 9<a>, a circle c is described passing through the point 7. With the same radius and with centre 16, an are L' is described. A line L is then drawn parallel with the bar 12 and at a distance from the axis thereof equal to the radius of the circle c, such line cutting the arc L<1> in a point L<2>. With L' as centre, an arc C is then described having the radius of the circle c. Then this arc is the axis of the curved portion of the bar 12 which engages the set-screw 16 when an angle less than a right-angle is being trisected. The instrument is not used for trisecting angles greater than a right-angle; but angles' of any size may be bisected by providing straight, slots 14 in the bars 12, 13 and by mounting a slotted axial bar 9 on the pivots 6, 8

Title: Improvements in or relating to broaching machines
IPC: B23D37/04
Filed: 1943-02-01
Abstract: 561,619. Broaching. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.). Feb. 1, 1943, No. 1652. [Class 83 (iii)] A broaching-machine has a return pullerhead with a broach-engaging latch associated with positive locking means moved alternately to locking and unlocking positions. In the application to the broaching-machine described in Specification 554,500 having a rotatable work-holder carrying a number of work-pieces with broach return tubes between the work stations, the frame has guideways for a return puller-slide 14 actuated by a hydraulic cylinder 16. After the pull broaching-stroke of the main ram, the broaches are pushed back through the return tubes to a position wherein the notched rear ends of the broaches are latched to the return puller-head which completes the return broach movement to a point where they entirely clear the work. The return pullerslide 14 is connected to its piston-rod through a bushing 20 giving lost-motion between flanges 22, 27. Each broach when returned by the main ram is received in a head 30 carrying a spring-urged pivoted latch 33 which engages the notched end 37 of the broach B. Each latch has a conical recess 40 coacting with the end of a locking rod 42 to lock the latch in position, Fig. 7, during the return movement. The heads 30 are mounted on tubular supports 50 secured to an annular member 51 connected, Fig. 5, to a bracket 53 on the slide 14. The locking-rods 42 are secured through spring connections 64 to a ring 60 connected through a lever 70 to a bushing 25 on the piston-rod 17. As the broaches are moved to the left by the main ram they are latched in the heads 30, whereupon the cylinder 16 is actuated. The first movement of the piston-rod actuates lever 70 to advance the rods 42 to their locking position, Fig. 7. The slide 14 is then moved to the left against spring abutments to withdraw the broaches clear of the work. After indexing the work-holder the piston-rod 17 is returned to the right, the first movement serving to unlock the latches 33 and the continued movement pushing the broaches into locking engagement with the main ram which is then actuated to effect the broaching-stroke. The broaches are subsequently again returned through the return tubes into engagement with the latches 33, whereupon the cycle is repeated.

Patent GB-474282-A (GB)
Title: Improvements in and relating to the manufacture of steel
IPC: C21C7/064
Filed: 1936-01-24
Abstract: In the desulphurization of steel by means of alkalies such as soda or potash, sufficient alkali is added to the molten bath so that the slag covering the molten metal is super-alkalized, thus ensuring that further sulphur is absorbed by the slag during a dead melt period after the finish of the heat.  The process described above may be applied to the manufacture of steel by the basic bessemer or Thomas process, or the basic open-hearth or electric processes and may also be applied to the acid processes. When carrying out the basic bessemer process, the alkali addition may be made before, during or after the blowing operation and is preferably made in two portions, the first at the beginning of the blow and the other after the blow, and the heat is held after the finish of the blow to allow further desulphurization by the alkali.  If the amount of manganese in the iron to be treated in the basic bessemer and other processes is insufficient, the sulphur present in the iron is largely removed before the addition of the required amount of manganese, preferably in the form of molten ferro-manganese, is made to the iron. Specification 474,224 is referred to.
