Abstract: 772,968. Hypodermic injection appliances. SCHERER CORPORATION, R. P. July 18, 1955 [Sept. 7, 1954]; No. 20759/55. Class 81(2) In a needleless hypodermic injector having primary and secondary plungers, for effecting a two stage injection, the spacing between the primary plunger and the ampoule piston is made adjustable to vary the force of the initial impact. In the form described the power spring 59 bears on a flange 52 on the primary plunger 58, which slides concentrically within the secondary plunger 60, the arrangement being such that the plunger 58 first engages the ampoule plug 18 over a small area, and ejects a small quantity of medicament at high pressure, and then the flange 52 engages the top 63 of the secondary plunger 60 and both plungers advance as a whole, bearing on the entire surface of the piston. The apparatus is set by screwing up the shaft 55 within a threaded collet 40, to compress the spring 59, and this is released, when desired, by depressing a plate 70 which, through drawbars 48, disengages a ring 46 from the collet, which opens and releases the shaft 55. The distance A, separating the end of the plunger 58 from the piston 18, which determines the force of the initial impact, may be adjusted, after the injector has been set, by raising or lowering the whole plunger and collet assembly, by positioning the holder 36 in the threaded part 15 of the main body 10. If less than the full volume of liquid is to be injected; the ampoule holder 14 is screwed further into the body 10 so that the piston 18 displaces the unwanted quantity of medicament before the injection is made.

Title: Improvements in wireless telephony systems
IPC: H03C5/00
Filed: 1920-07-10
Abstract: 148,955. Soc. Franþaise Radio-Electrique. Oct. 26, 1916, [Convention date]. Wireless telephony and telegraphy.-The exciting winding of a high-frequency alternator is fed with current undulated by a microphone and then amplified. In one method the circuit of the exciting coil is coupled with a microphone circuit and also with a circuit containing a negative resistance such as an are, the reaction of which tends to neutralize the ohmic resistance of the circuit. Another method illustrated in Fig. 2 employs high-frequency current which is rectified after being modulated by the microphone. Oscillations supplied at the terminals 1, 2, pass through ironcored coils 3, 5, and are modulated by the microphone coupled to a separate winding on the cores of the coils 3, 5. A mercury rectifier 9 then serves to supply rectified current to the exciting-winding 8 of the alternator. The coils 3, 5 may be combined with the transformer 7, or the rectified current circuit may be coupled with the coils 3, 5, giving rise in some conditions to continuous oscillations. The oscillations supplied to the terminals 1, 2, may be those of the alternator itself, which thus becomes self-exciting. The microphone is protected from high-frequency currents by an inductance or a rejector circuit. In order that there may be zero exciting current when the microphone is silent, the effect of the rectified current in the coil 8 may be counteracted by permanent excitation in the reverse direction, or a transformer may be interposed. At the receiving station the received oscillations are superposed on local oscillations of the same frequency but greater strength.
