Filed: 1938-10-20
Abstract: 520,441. Springs. CLEVELAND, F. J. (Bendix Aviation Corporation). Oct. 20, 1938, No. 30406. [Class 108 (iii)] [Also in Groups XXIX and XXVII] Damage by vibration of the mounting of a flexible pressure responsive member such as a bellows 10 is prevented by damping means, such as oil 32, Fig. 1, an air dashpot 52, Fig. 3, or an external rubber sleeve frictionally engaging the bellows, a universal connection being provided between the latter and the valve 22 or other device to be controlled. The parts 18, Fig. 1, or 56, Fig. 3, co-act with the surrounding sleeves to prevent harmful distortion, and a further sleeve depending from the fixed member 12 may have a thickened end to drag in the oil or may by its proximity to the corrugations of the bellows hinder oil-flow therebetween. In Figs. 4 to 6 (not shown), the device is applied to fuel or other valves of internal combustion engine carburetters, the bellows being subject on one side to intake pressure, in one case acting through a diaphragm, the flexing of which forces oil into or out of the bellows which is connected to an economizer valve through a rocking lever the other arm of which is connected to a second oil-damped bellows responsive to variations of atmospheric pressure.

Title: Printing apparatus
IPC: B41J9/32
Filed: 1973-06-29
Abstract: 1432984 Selective printing TELETYPE CORP 29 June 1973 [3 July 1972] 31061/73 Heading B6F For use in an "on the fly" printer a hammer driving mechanism includes an impeller 84, an interposer 92 movable by an electromagnet 125, when energized, to provide momentum transfer from the impeller to slidable hammer 86, the mechanism being such that after the momentum transfer has been completed the interposer is out of the control of the electromagnet 122. For each hammer 86 there is an interposer 92 controlled by armature 124 of electromagnet 126. When it is energized one end of the interposer 92 is moved into the path of rotating teeth 83. One of the teeth engages it and causes it to drive the hammer 86 forward. In so doing the interposer 92 is rocked so that its end 99 is moved out of contact with surface 138 of armature 124. This ensures that if the electromagnet is still energized the hammer cannot be hit twice accidentally. On de-energizing the Fig. 2 position is resumed. Springs 110, 166, 170 bias the hammer armature and interposer to their respective Fig. 2 positions.

Abstract: 227,106. Krupp Akt.-Ges., F. Dec. 31, 1923, Convention date]. Void [Published under Sect. 91 of the Act]. Electromagnetic switches. -A reverse-current relay for operating a main switch in the event of reverse. current, in which the action is unaffected by a substantial fall in voltage, comprises a centrally-pivoted member c<3> carrying a contact c' to bridge fixed contacts d<1>, d<2>, and two armatures c, c' each acted on by its own horse-shoe electromagnet A, B energized by current and voltage windings. The current windings e<3>, e<4> are in series and are wound in the same sense; the voltage windings f<1>, f<2> are in series also, but are wound one in one direction and the other in the opposite direction. A light control spring G ensures that, with no current, the relay assumes the position shown. A current in the normal direction, indicated by the arrow X, causes the energization of the magnet A by the winding e<3> assisted by the winding f<1>. The, magnet B, however, is weakly energized because its windings oppose one another. Consequently, the relay is maintained in the off position. With reversal of current, the windings of magnet A oppose one another and those of magnet B aid one another, so that the contact arm is brought to the closed position where it completes a voltage-energized circuit for the main switch e<1> which is brought to, the off position against the action of the spring e<2>.

Title: Improvements in or relating to absorption refrigerating apparatus

Abstract: 654,612. Refrigerating. ELECTROLUX, Ltd. Dec. 3, 1948, No. 31341. Convention date, Dec. 19,1947. [Class 29] In refrigerating systems of the continuous cycle inert gas type having in the boiler unit a column 11 of strong liquor in free communication with an absorber vessel 18 and communicating with the inlet to the circulating pump 12, part of the strong liquor flows from the absorber system to the column 11 through a liquid heat exchanger 14 and the other part flows from a point above the liquid level in the absorber vessel 18 through a vapour space for expelled vapours for rectifying or analysing purposes and then flows to the column 11. This arrangement also ensures that the thermal capacities of the liquor flows in the heat exchanger shall be the same. As shown in Fig. 1, part of the strong liquor flows by a pipe 19 to a chamber 39 through the bottom of which passes a pipe 20 capped by a member 23 the inner surface of which cooperates with the outer surface of pipe 20 to form capillary channels. The liquor passes up these channels and trickles down a lining 22 in the tube 20 of wire gauze. Expelled vapours flow from the boiler 11 through a pipe 21 and are analysed while passing up pipe 20 to a conduit 31 leading to the condenser. The liquor flows from the base of the pipe 20 and is pumped by pump 25 to the column 11. As shown in Fig. 3, a sump 34 located in the lowest coil of the absorber 32 traps some of the descending liquor. Through the bottom of the sump extends a pipe 35 capped by the member 23. The liquid in the sump rises in the capillary channels and flows through pipes 35, 36 and a hole 30 to the liquid column 11. The pipe 36 is located within conduit 31 for the expelled vapours which are rectified by the cooler liquid in the pipe 36. Vapour generated in the pipe 36 enters conduit 31 through a hole 37 which is located above the liquid level in the pipe 35. The hole 30 is located below the liquid level in the pipe 35.

A second pressing tool 15 having ribs 16 similar to the ribs 9 of the tool 8 is preferably provided, the tool 15 being rotatable in the same direction as the pattern roller. The ribs 16 may, however, have cutting edges to remove torn-off lugs 14 left in the material by the action of the tool 8 ; to facilitate the removal of the torn-off lugs, a sloping supporting head 18 is provided in front of each stud 6. The edges of the apertures are smoothed out about the studs 6 by means of a roller 19 provided with a covering 20 of resilient material. The tool 8 or the tool 15 may be formed as a rubber roller having a smooth cylindrical surface in which case the tool may have the same peripheral speed as the roller 4, and the studs 6 may each have a bevelled surface 13, Fig. 4, provided with a cutting edge 21. In a modification, Fig. 6, the pressing tool, which may be cylindrical or conical, is in the form of a rotatable circular disc 24 having radial ribs 26 similar to the ribs 9 of the tool 8.
