Abstract: 733,296. Hypodermic syringes. HEIN, G. N. Nov. 2, 1953 [Dec. 4, 1952], No. 30258/53. Class 81 (2). In a hypodermic injection device comprising medicament chamber, plunger, power meansall within a casing-the power means is potentialized and cocked by a lever mechanism, a lever of which is pivotally connected to the casing exterior. The device shown comprises a tubular casing 10 provided at one end with a needle-less nozzle assembly 18 and a medicament chamber which receives a rubber ampoule 14 integrally formed with a tail-piece 15 which on operation of the device is thrust by the end 20 of a spring-loaded plunger 24 into the ampoule and at the other end with a casing 28 containing power " cocking " means. The plunger is "cocked" by being drawn rearwardly of the casing by swinging a lever 26 from the position shown in Fig. 2 to that shown in Fig. 3. This U-shaped lever, embracing both sides of the device, is pivotally mounted about an axle 27 extending through the casing 28 and is formed with notches which engage a pin 31 also extending through the casing 28 but is free to move in an arcuate path defined by slots 35 cut in the casing walls. The pin is threaded through aligned apertures in crankpieces 34 and a shaped link member 32 which is pivotally attached at its other end to the plunger 24. Movement of the pin from left to right (Fig. 3) causes the crank pieces and link to rotate anti-clockwise, thus pulling the plunger back against the spring 21. When the pin 31 is beyond the line drawn between pivot centres 33, 27,-the device is " cocked " and the lever may be returned to its original position (Fig. 2). A spring-loaded push button 36 with an inclined surface 39 formed thereon is thrust inwardly to release the plunger, the surface 39 causing the top of the link 32 to move downwardly below the above-mentioned line. For safety purposes a rod 40 formed with arcuate face 43 is provided, the face when the external control knob 41 is in " safe " position, being adjacent the rear end of the casing 28, whereby a square edge of the rod may engage a recess 44 in the link, thereby preventing its movement from the " cocked " position. Accordingly, prior to the pressing of button 36 the knob 41 must be turned through 180 degrees to bring the rod face 43 adjacent the link 32.

In a system for controlling the exhaust gas pressure delivered to the turbine 16, Fig. 1 of an I.C. engine turbocharger, the exhaust gases are by-passed around the turbine to hold its speed down until the full lubricating pressure exists. Exhaust gases from manifold 12 are normally ducted directly to turbine 16 which drives compressor 18 to supply charging air to inlet manifold 11. A valve 32 controls the bypassing of exhaust gases through passage 28 to the turbine outlet. An oil supply line 66a, 66b to bearings 63, 64 also supplies oil pressure to chamber 68, excess oil being returned to sump 71. The charging air pressure in passage 27 is communicated to chamber 49 through passages 72a, 72b and a spring-loaded valve 74. When the engine is started valve 32 is normally open to by-pass the turbine until rising oil pressure in chamber 68 acts on wall 53, Fig. 3 (not shown), spring 59 and wall 48 to close valve 32. At excessive charging air pressure valve 74 opens to admit air pressure to chamber 49. This acts on wall 48 which is connected to valve 32 thereby moving the latter to the by-pass position.

[Class 61 (ii)] A tool for dismantling and assembling shock - absorbers of the type shown in the drawing, is shown in position on a shock absorber during dismantling ; the fluid casing not being shown and a valve in a piston 5 being out of sight. The shockabsorber itself acts by transmitting the shock from the vehicle wheel through a rocker lever to a disc 2b, on which one end of a spring 1 bears, the other end bearing against a disc 2a. The disc 2b is attached to the piston 5, which compresses liquid in a chamber 1<a>, and forces it partly through a valve in the piston and partly through a valve 4 into a casing, which envelops the shock absorbing elements. When the vehicle falls into a cavity the reverse action results. To dismantle, a casing 9 is put into position as shown, the casing having jaws 9<a> working in inclined slots and capable of engaging between the convolutions of the spring. By means of a mechanical device such as a screw 13 a plate 13a is forced downwardly compressing the spring, which has been previously anchored at one end by the jaws 9a, and forcing downwards the cylinder and piston so that the disc 2b is out of the way for the engagement of a spring locking ring 8 with a suitable tool such as tongs 14. By freeing the spring ring from a groove in the cylinder the shock absorber may be dismantled. Hydraulic or other means may be employed in lieu of the screw press.
