IPC: F04F5/46
Abstract: 113,524. Delaporte, M. March 27, 1917. Aspirating apparatus, ejector for extracting air and other non-condensable gases from steam condensers by means of two or more steam ejectors working in series, with or without intermediate auxiliary condensers, and consists in improving stability by introducing water or other liquid into the ejectors in small quantities. According to the arrangement shown in Fig. 1, gases to be extracted are drawn through an inlet 6 and discharged from an outlet 7 by means of a series of three ejectors 1, 2, 3 and two auxiliary jet condensers, 4, 5, a water supply to ejectors 2, 3 from a receptacle 8 being controlled by valves 11, 12. These valves may be regulated automatically so that the supply is cut off when instability becomes unlikely, owing to increase of pressure in the auxiliary condensers, or regulation may be effected by selecting suitable differences of level between the ejectors and the receptacle. Alternatively, the water may be conducted to the ejectors by way of the induced-fluid connexions, and it may be derived directly from one of the auxiliary condensers through which the induced gases have already passed. Thus a jet condenser may be supplied with condensing-water that has already acted as the condensing medium in a surface condenser, constituting the auxiliary surface condenser between two steam ejectors engaged in extracting air from the jet condenser, and from which the condensate passes by gravity into the second steam ejector. Specifications 3811/14 and 3882/14 are referred to.

Title: Indicating or controlling systems such as apparatus for indicating or controlling the course of craft
IPC: B64D45/00
Filed: 1942-08-13
Abstract: 611,006. Electric control systems. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Aug. 13, 1942, No. 11368. [Class 40 (i)] [Also in Group XXXV] In an indicating or control system for moving craft, the rate of turn from course is measured and the time-integral thereof is obtained as the voltage across a condenser which is charged or discharged by a current proportional to the measured rate of turn. The arrangement is applicable to automatic steering apparatus in which a servomotor is controlled in accordance with the angular deviation, that is, the time-integral of the rate of turn, and also in accordance with the rate of turn and its first derivative. In the Wheatstone bridge network shown, two ratio arms include tetrodes 19, 20, the grid control voltages of which are obtained from the rate of turn instrument while the other two ratio arms comprise a pair of constant current devices 23, 24 such as cathode-loading triodes. The rate of turn instrument may be of the type described in Specification 611,005, in which case the alternating voltage output requires rectification and possibly demodulation. The diagonal of bridge comprises in series a resistance 12, inductance 13 and condenser 14, and when the bridge is unbalanced by an increase of grid voltage of one tetrode and a decrease of that of the other the voltages across these elements are proportional respectively to the rate of turn, to its first derivative and to its time-integral. The sum of the three voltages may be used to control the servomotor or they may be applied separately. The arrangement may also be used in conjunction with a pitch detector for maintaining an aircraft in level flight. Specification 247,633, [Class 97 (iii)], also is referred to.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B17/30
Filed: 1940-07-11
Abstract: 537,172. Roll-film cameras. KODAK, Ltd. July 11, 1940, No. 11557. Convention date, Nov. 4, 1939. [Class 98 (i)] A roll-film camera is provided with a spring spool support mounted in a supply chamber adjacent the exposure frame and exerting a thrust on the spool in a direction away from the exposure frame, so that the spool flanges are urged against the camera body to exert a braking action on the spool. As shown in Figs. 2, 3 a bracket 12 is secured by means of a spring member 20 within the spool chamber, and is formed with upturned ends 13 with projections 14 between which are secured spindles on which are mounted rollers 17, 18. The film spool is inserted by thrusting it in the direction of the arrow A, the flanges 25 snapping past rotatable sleeves 28 at each end of the roller 18, the spring mounting of the bracket then causing the sleeves 28 and roller 17 to bear on the spool flanges and force them into contact with the end wall 24 of the camera to produce a braking effect. The film passes over the roller 18. Increase of tension in the film during winding causes the flanges to bear less heavily on the camera wall and reduces the braking effect, so allowing the whole length of the film to be wound without substantial variation of torque on the winding key. In a modification a spring carries a single roller bearing on the spool flanges and is formed so as itself to bear on another part of the flanges. Fig. 5 shows another form, in which spindles 57 extending outside the spool flanges are positioned between pads 54, 59 formed on the moulded body and back of the camera, and the spool flanges pressed against the end wall by a spring 56 engaging the spindles.

Abstract: 1366626 Jointing by stamping; making electrical connections RELIABLE ELECTRIC CO 12 March 1973 [13 March 1972] 11707/73 Headings B3A and B3Q [Also in Division H2] A channel-shaped connector 2, Fig. 20, on a tape 30 is crimped to wires between a die 102, Fig. 3, and an anvil 154 in a machine comprising a wire holder 128 mounted on the die for inserting the wires into the connector, a shear block 164 movable relatively to the anvil 154 and having cutting edges 182, Fig. 9, for trimming wire ends protruding from the connector against cutting edges 152, Fig. 8, on the die, and cutting edges 186 on the block 164 for serving the tape 30 against edges 188 on the anvil. The die is driven, through a toggle linkage 118, 124, by a pivotally-mounted pneumatic cylinder 108 which includes an internal return spring and an external spring 114. A safety arrangements includes two central valves in series, the supply being diverted to a feed cylinder 87 when a button 208 is depressed by an abutment 206 having a lost-motion connection with a piston, Fig. 10 (not shown), in the cylinder 108. A toothed feed-wheel 70 engaging the strip of connectors is advanced in steps through a one-way clutch by the pivotally-mounted feed cylinder 87; the wheel 70 may also be turned by a hand wheel (82), Fig. 2 (not shown). A spring (85), Fig. 14 (not shown), locates in index slots (76) at each advance of the wheel 70. A polyethylene tape bonded to connectors having phosphor bronze linings 18 on copper or annealed brass shells 4 is fed up to the anvil 154 through an opening 64 in the machine casing. The wires to be joined are each placed in the die 102 and gripped between a pin 136, Fig. 8, and a spring 134 on the wire holder 128. The die is advanced bringing the wires against abutments 180 on the shear block 164 which is deflected against springs 172 in the anvil holder 158, Fig. 9, so as to sever the tape 30 between the shearing edges 186, 188. Further movement of the ram trims the wire ends between the shear edges 152, 182 and effects the crimp. The anvil 154 may be adjusted by a screw 176. Delay in operation of a valve in the housing of cylinder 196 and possibly also the slower action of the feed cylinder 87 allows the die 102 to retract before the next connector is advanced. Projections 250, 252, Fig. 23, may be provided in the die so that if the wires are cut before the tape, pins 250, 252 will engage and move the shear block 164 for severing the tape. The wire ends 270, Fig. 25, may be drawn inwardly of a connector 2 by providing the shear block 164a with forward projections 200, 262.
