Title: Improved variable mechanical advantage lever
IPC: G05G7/04
Filed: 1962-03-19
Abstract: 979,316. Linkwork; brake actuating mechanisms. N. C. POWRIE. Feb. 26, 1963 [March 19, 1962], No. 10456/62. Headings F2E and F2K. [Also in Division B7] In a variable mechanical advantage lever system for applying a thrust to a pitman 18, e.g. for operating the brakes of a motor vehicle, a lever 10 pivoted at 11 has an effort arm 13 and a shorter working arm 14 formed with cam forces 16, 17, 15 which are engaged by a roller follower 19 on the pit-  man, so that when the effort arm is moved anti-clockwise against a bias spring 12 the cam rise 17 first causes the pitman to move with a low mechanical advantage to take up slack in the system, after which the slope of the face 15 provides a high mechanical advantage for the braking effort. Further movement of the lever reduces the mechanical advantage to allow a pumping action if fluid in an associated hydraulic system is low. Guide links 20 pivoted at 21 to the pitman constrain the latter to substantially linear movement. The lever arm 13 may carry a pendant pedal, or in another form (not shown) a pedal above the pivot 11.

Abstract: 437,945. Photographic lens fittings and mounts. BILLING, N. P., 6, Lower Regent Street, London. April 6, 1934, No. 10519. [Classes 97 (i) and 98 (i)] A tubular lens turret constituting the front of a photographic camera is collapsable wholly or mainly into the camera body. As shown to the front of a rectangular camera casing 1 having in its upper wall an aperture 2 is secured a plate 3 integral with which is a drum 11 having an aperture 12 corresponding to the aperture 2, the apertures 2 and 12 being used for reflex viewing. Threaded into an aperture in the plate 3 is a tubular member 5, and threaded into member 5 is a tubular member 6. Pins 14 secured to the members 6 engage a groove in a ring 9 to hold the ring 9 against the flange 13 of the member 6. Threaded into the ring 9 is a tubular member 7. Relative movement between members 6 and 7 is prevented by co-operation of a key on the member 6 with a keyway or the member 7. Rotation of the ring 9 effects focusing. In the member 7 are two coaxial cylindrical blocks 19, 20 and in front of block 19 is a cover plate 21. Each block has four apertures 22-25 in each of which is secured a lens element. Between the blocks is a rotatable disc 26 containing a series of different lens stops 27 and integral with a sleeve 34. Behind block 20 is a rotatable disc 28 bearing colour filters 29 and with one blank aperture 30, and integral with a sleeve 31 rotatable on a spindle 32 extending from the back plate 33. The back and front plates 33, 21 are held together by a stud 35 the head 41 of which is connected by a grub screw to the plate 21 so that the plates 21, 33 and the spindle 32 can be rotated as a whole relative to member 7. The assembly is located in the desired positions by engagement of a plunger in block 19 with recesses in plate 21. Sleeves 31, 34 have manipulating arms 37 having pins engaging locating holes in plate 21. The lenses are located in operative position by engagement of detents 47 on the member 6 with appropriate recesses on the member 5. The back and front plates 33, 21 each have a single aperture 43, 42. The camera may have a slide 123 which is secured to the support. In a modification the carriers for the front and rear lens elements may be relatively angularly adjustable so that different lens combinations may be obtained.

Fastenings for sliding shutters ; locks, preventing release by destruction.-A hinged metal rolling shutter 4 is locked by a plate 19 having abutments 5 which pass through holes in the partition 31 of the side guides 1, 2 to rest over the hinges 4<1> under the action of the springs 3. the plate 19 being blocked by a hinged flap 6 which is turned through 90‹ by the shooting of the bolt 9 of the shutter lock, to fill up the space in the guide 2 and prevent the backward motion of the plate 19. The flap 6 has a projection 7 by which it is operated by the bolt 9, the projection engaging in a slot 15 in the bolt in the locking position. The end 9 of the bolt is detachably connected with the other part 8 of the bolt by a pair of hooks 10<1>, 14<1>. If an attempt is made to force the bolt by a prising tool, the part 8 is pushed inwards sufficiently to disengage the hooks, bearing the end 9 still in operative position. Instead of being hinged, the flaps 6 may slide vertically, being operated by the forked inclined ends 28 of a bolt, Fig. 7, to cause pins 29 to slide along inclined slots 24 in pivoted levers 23, to bring their ends 12 into locking position on the hinges 4'. The plate 6 may itself have projections which, when the plate slides vertically and laterally, abut over the hinges.

[Also in Divisions E1 and Fl] 11 The invention relates to a well-drilling turbine, the turbine being of the multi-stage type and there being a by-pass valve for adjusting the flow of working fluid through the turbine depending on the speed of the turbine shaft. The blades of the turbine are so shaped that the angle of discharge of the working fluid from the stator blades equals or approaches the angle at which the fluid enters the rotor blades when the rotor is stationary, the angle of discharge of the fluid from the stationary rotor being equal to or approaching the angle at which the fluid enters the following stator blades. The by-pass valve is built as a multi-stage valve. The multi-stage axial-flow turbine in Fig. 1 comprises a solid rotor shaft 5 on which are mounted rotor blade rows 4 which co-operate with stator blade rows 2 mounted within stator casing 3, the rotor being supported by means of bearings 6, 7. Turbine working fluid passes to the turbine through a duct 10 within casing 9 in which is disposed also a multi-stage by-pass valve 8, the valve opening to an outlet 11 in the casing 9 through which the working fluid may pass to the bore-hole. The by-pass valve comprises a series of frusto-conical rubber sleeves, each of which has a ball mounted therein, the sleeves expanding to allow flow of fluid therethrough in the event of the pressure exceeding a predetermined value. In a second embodiment the turbine rotor shaft is hollow and the by-pass valve is accommodated therein.
