Title: Flux composition for soldering
IPC: B23K35/36
Filed: 1974-02-27
Abstract: 1405573 Solder flux W R GRACE & CO 27 Feb 1974 8914/74 Heading B3R [Also in Division C7] A solder flux comprises in per cent weight at least 60% NH 4 Cl+ZnCl 2  with the NH 4 Cl forming 44-54%, and 1À5-10% powdered magnesium silicate. The flux may also contain 0À1-1% of a resin melting at 250-360‹ F., e.g. by extracting pine wood in aromatic solvents, modified resules of phenol formaldehyde type such as a resule modified with glycerine ester of rosin or with pentaerythritol ester of rosin up to 12% light siliceous material such as penlite, exfoliated vermiculite, pumice and diatomaceous earth may be included as well as up to 22À5% of alkali metal chlorides and 5-25% of ZnO or ZnCO 3 .

Title: Improvements in carburetters for internal combustion engines
IPC: F02M7/26
Filed: 1919-04-08
Abstract: 144,424. Dodson, E. April 8, 1919. Spray carburettors.-In a mixed-flow carburettor with a progressively emptied fuel-well of known type, the supply of air to the said well is controlled by a member actuated from the throttle valve, the object being to obtain a relatively weak mixture at all throttle openings except full or nearly full, at which latter openings a rich mixture is obtained for maximum power. The well 9 is fed from the float chamber 1 through a restricted orifice 8 and, from its upper end, feeds the fuel nozzle 10. A perforated air inlet tube 11 projects into the well, the upper end of the tube receiving air, when permitted to do so by a plunger 13, either from the atmosphere direct or, in the case of aircraft, from a " pressure balance system " comprising a pipe 21 which places the top of the float chamber in communication with the air intake 2. The plunger 13 works ..n a barrel 12 provided with an enlargement 15 in communication with the air supply. The plunger is slotted at 14 and the length of slot exposed to the enlargement 15 is determined by a cam 18 on the throttle spindle 19. An independent adjustment of the plunger may be effected by actuating a wedge 16 on a lever 17 from the driver's position. The mechanical connexion between the throttle and plunger may be of the kinds described in Specifications 138,177 and 144,830.

Title: Improvements in or relating to automatically controlled machine tools
Inventor: JUDSON CHARLES ALAN
Filed: 1956-03-23
Abstract: 862,972. Electric measuring and control systems. BIRMINGHAM SMALL ARMS CO. Ltd. March 21, 1957 [March 23, 1956], No. 9066/56. Class 40 (1). [Also in Groups XXII and XL (b)] In a machine tool such as a lathe in which the tool is controlled from a coded record, excessive wear of the tool is detected by a vibration detector resting on the cutting-tool, or by a stylus resting on the machined workpiece, or by a differential photo-cell arrangement comparing the light reflected from the machined workpiece with that from a standard workpiece. The detectors produce an increased output with tool wear, which, after amplification and rectification operates a thyratron or other relay to energize an alarm circuit, and initiate means for automatically replacing the worn tool and repositioning it relative to the workpiece. The thyratron or relay is delayed from returning to its normal condition for a predetermined time. If another fault signal is received during this delay a further alarm is operated and the machine stopped. Specifications 841,682, 860,255, 860,256 and 860,257 are referred to.

Title: Improvements in or relating to record feed mechanism for printing transferring machine
IPC: B41L11/00
Filed: 1942-07-02
Abstract: 559,458. Copying documents ; ratchet gearing. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 2, 1942, No. 9142. Convention date, July 1 1941. [Class 100 (ii)] [Also in Group XXIV] In a machine such as described in Specification 535,665 for copying from a mirror script original line by line, a feed roller for the original is actuated by ratchet mechanism provided with means whereby the pawl may be rendered inoperative at alternate operations of the machine so that two impressions may be made from any line or from every line. The shaft 138, Fig. 3, of the feed roller is normally driven step by step to advance the original one line for every operation of the machine by a ratchet wheel 144 and a pawl 145 which is mounted on an arm 146 oscillated about the shaft 138 by a link 147 and an oscillating cam 150. Any desired line may be printed from twice, by actuating a key 180 which turns a bell crank lever 181 so that one arm 183 engages a pin 184 on the pawl 145 to raise the pawl clear of the ratchet wheel. The bell-crank lever is held in this position by a latch lever 187 engaging an arm 185 on the bell-crank lever until, on the next upward movement of the link 147, a trip member 188 thereon engages a pin 189 on the latch lever to turn it in a clockwise direction to release the arm 185 and allow the bell crank lever and key 180 to be returned to normal position by a spring 190. To allow automatic printing twice from each line of the original, a disc 191, is provided which can be turned into the position shown in Fig. 3, in which a projection 193 thereon is in the path of a lug 194 on the link 147, or can be turned as in Fig. 4, to a position in which the projection, is clear of the lug. Two hooked members 195, 196, pivoted to the disc 191 are urged towards each other by a spring 197, when a cam member 198 which normally spreads the members 195, 196 apart as shown in Fig. 4, is turned to the position of Fig. 3. For normal single printing, the parts are in the position of Fig. 4 but when double printing is desired, the disc 191 and cam 198 are turned manually to the position of Fig. 3. When the link 147 moves downwardly, the engagement of the lug 194 with the projection 193 arrests the link before the pawl 145 can engage the next tooth, but not before the pin 200 of the cam follower 149 is engaged by the hook of the member 195. On the next upstroke of the link, the ratchet wheel is not turned but the disc 191 is turned to the inoperative position. On the next downstroke of the link 147, the pawl engages the next tooth of the ratchet wheel and the pin 200 is engaged by the hook of the member 196 so that on the upstroke of the link 147, the ratchet wheel is turned and the disc 191 is again turned to the position of Fig. 3.

In the form shown, auxiliary elevators 52 are provided in addition to the auxiliary rudder, the auxiliary surfaces being normally inoperative in the neutral position, forming part of the tail stabilizing surfaces, but being brought into operation automatically at low speed when the flaps 19 are lowered. The auxiliary rudder is moved in the direction required to counteract the unbalanced forces arising rom the engine torque and propeller slipstream, while the auxiliary elevators are raised to assist in maintaining the taildown attitude. The flaps 19 are operated by a hydraulic piston and cylinder 29, 30 controlled by a selector valve 22 and lever 24, and the auxiliary rudder 6 by a second piston and cylinder 12, 13 controlled by a valve 23, which is so arranged that it does not open until the flaps are deflected through about 20 degrees. A further piston and cylinder connected to pipe-lines 58 operates the auxiliary elevators. The control transmitting mechanism may be operated electrically or pneumatically instead of hydraulically, while the auxiliary surfaces may be operated automatically upon lowering of the undercarriage instead of the flaps.
