Abstract: 397,561. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Knight, D. B. ; 225, Lincoln Place, Brooklyn, New York, U.S.A.) March 2, 1932, No. 6312. Convention date, March 2, 1931. [Class 29.] Absorplion systems. -Refrigerant vapour evolved in the heated generator 10, Fig. 1, of a continuous-cycle machine, preferably of the inert gas type, passes through analyser plates 33 and flows by a pipe 12 to a pumping chamber 13, to which strong liquor flows from the absorber 35. The vapour lifts the liquor through an apertured pumping pipe 14 to a separator 15, whence the liquor flows through a U-pipe 16 to the top of the analyser while the vapour flows on to the rectifier 18 and condenser 20. The rectifier 18 is cooled by evaporation of condensed refrigerant in known manner, and thus the evolved refrigerant vapour is cooled at three different points before liquefaction. The strong liquor in its passage through the analyser conveys solvent back to the generator. The pumping-chamber may be provided with a vapour byepass connection with the separator 15 or with the rectifier, as described in Specification 397,821, so that on excessive generation of vapour the byepass is uncovered and a part of the vapour passes on directly without entering the pumping pipe. In the system shown in Fig. 2 a horizontal generator 37 with a stand pipe 38 containing analyser plates 39 is employed. A riser 42 leads to a second analyser 43. The vapour for the pumping chamber is led from the first analyser through a pipe 46, while the rest of the vapour rises through the pipe 42. The strong liquor flows through the upper analyser and then through a U-tube 44 to the top of the lower analyser.

Filed: 1939-02-27
Abstract: 517,801. Speedometers. PRACISIONS MECHANISCHE UND OPTISCHE ANSTALT F. SUSS AKT.-GES., and KELER, T. VON. Feb. 27, 1939, No. 6363. Convention date, Feb. 25, 1938. [Class 106 (iii)] In a speed indicator the shaft 1 whose speed is to be measured drives a worm wheel 2 which displaces a screw bolt 3 in the direction of its length. The bolt is rotated by a wheel 4 engaging with a disc 5 rotating with predetermined speed. As the shaft 1 moves the bolt the gearing relation between wheel 4 and disc 5 changes until the speed of rotation of the bolt is such that the longitudinal motion of the bolt due to the engagement of its screw threads with wheel 2 is sufficient to counterbalance the straightforward longitudinal shift due to the rotation of wheel 2. This position of the bolt is characteristic of the particular speed of shaft 1 and thus indicating means connected to bolt 3 will show the speed. The disc 5 may be driven by change speed gearing 8 in order that the scale of motion of the indicator may be modified if desired.

Abstract: 798,827. Hypodermic injection devices. Z. & W. MACHINE PRODUCTS, Inc. Aug. 27, 1954, No. 6462/58. Divided out of 798,826. Class 81 (2). A needleless hypodermic injector has a plunger for discharging medicament from a medicament chamber, a reservoir carried by the body of the instrument for replenishing the medicament chamber and adjustable means for transferring a selected volume of medicament from the reservoir to the chamber. The plunger 6 and a plunger extension rod 15, which are slidable in a piston housing 3, have a bore 92 through which medicament passes into the medicament chamber A from the reservoir 104. The medicament chamber A is held between flanges 137 of a collet 136. The tip 124 of the plunger 6 forms a closure for the medicament chamber A and includes a ball valve through which medicament passes into the chamber A. The medicament reservoir 104 is threaded on the extension rod 15. On projection of a piston 107 within the reservoir 104 by rotation of a knob 116, medicament is transferred to the medicament chamber A. The face of the reservoir 104 adjacent the knob 116 has a cavity 118 containing a spring-pressed ball 119 and the knob 116 has four equally spaced depressions 117 which register in turn with the ball 119 as the knob 116 is rotated, thus giving an indication of the number of rotations completed by the knob 116 and the amount of medicament transferred to the medicament chamber A. Projection and retraction of the plunger 6 is brought about as described in Specification 798,826. The stroke of the plunger 6 is limited by abutment of a disc 102 secured to the extension rod 15 with an adjustable sleeve 98 threaded on the rear of the piston housing 3. A lever 140 pivoted on the housing 3 prevents inadvertent depression of a button 62 which is operated to release the plunger as described in Specification 798,826.
