Title: A method of making a welded lap joint
IPC: B23K9/007
Filed: 1947-07-31
Abstract: 624,596. Uniting by fusion. NORTON, J. B. July 31, 1947, No. 20724. [Class 83 (iv)] In lap-welding by the electric arc process, an arc is struck between the upper plate &c. and a coated metal electrode and when the spot is molten the electrode is lowered into the molten pool formed until it has fused through both parts, the coating enabling the arc to be maintained during lowering of the electrode. When both parts are penetrated the arc is broken by withdrawing the electrode so that the molten metal from the sides of the hole seals the bottom. The hole is then filled up by arc-welding, the arc being frequently broken so as to prevent the bottom of the hole from being again penetrated. A number of such welds may be made along the joint.

Title: Motion picture projectors
IPC: G03B31/02
Filed: 1971-04-19
Abstract: 1306471 Cine apparatus and editing EASTMAN KODAK CO 19 April 1971 [3 Feb 1970] 20992/71 Headings G2C and G2E A device for editing and splicing cine film is located in the film path of a cine projector and is designed to utilize the projector's projection system to view the film being edited. In the embodiment shown the operational sequence is as follows. First the film is fed, through the projector by means of its film transport mechanism viz a claw (29), Fig.1, (not shown), until the point, at which an unwanted length of film begins,is reached. This is found precisely by controlling the projector by a forward-stop-reverse switch (24). The projector is then stopped and an EDIT CUT button (27) pressed. This causes the film to be advanced from the projector's picture gate (23) to the device, this distance being equal to a,predetermined number of film frames, and the film is cut. Projection is now recommenced by means of the said switch (24) and continues until the end of the unwanted length of film is reached. A SPLICE IN button (28) is then pressed which advances the stopped film from the picture gate to the device, cuts the film, stores the edited film and splices the film together. As shown in Fig. 4, film 22 enters the device through mouth 30 and may pass out to a take up spool through exit 31 on to a store for edited film portions through passage 70. Editing is achieved by moving blades 54, 55 contacting stationary blade 52. When the EDIT OUT button (27) is pressed and the film has been advanced to the device, solenoid 39 is energized to move blades 54, 55 in the direction of the arrow against the action of a spring. Blades 52, 54 cut the film 22 and seal off the passage to the exit 31 and cam 78 is pivoted about 79 and causes the plate 64 to clamp the leading part of the film 22. The film, when pro-  jection recommences, is now fed into the passage 70 until stopped and the SPLICE IN button (28) pressed. This causes the solenoid 76 to be deenergized, after the film has been advanced from the picture gate to the device and the blades 52, 55 sever the film and close off the passage 70. The solenoid 41 see Fig.2, is now activated and this pivots the splicer 37 to abut the film 22. The splicer comprises a disc 105 having a number of tapes theron arranged to lie radially on the plane of the disc. One tape is used per splice and the disc 105 is indexed after each splice to align the next tape for the next splice.

Filed: 1960-06-15
Abstract: 932,566. Particle accelerators. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 15, 1960 [June 20, 1959], No. 21063/60. Class 39 (1). [Also in Groups XXXV and XL (b)] A variable polarization saturable magnetic circuit which may be used in tuning the resonant cavity of a particle accelerator comprises a closed magnetic core of uniform crosssection having a polarizing coil surrounding a part of its circumference, an open magnetic flux " distributer " being held against the core along the part surrounded by the coil to improve the uniformity of distribution of the magnetic flux along the core. Figs. 3 and 6 show the magnetic circuit 1, 3 used in a high-frequency self-inductance device 4 associated with an inductive cavity used to accelerate protons around a closed trajectory in the annular vacuum chamber 5 of a synchrotron. The accelerating potential difference at the electrodes 6, 7 on each side of the gap 8 is obtained from a variably tuned resonant circuit consisting of capacitor 9 and the device 4, the self inductance of which is varied by varying the polarizing current in windings 2 surrounding cores 1. The forty ferrite magnetic core frames 1 (Fig. 6), are housed between the outer and inner two coaxial lines, the outer being of copper covered steel plates 4a and 11 and the inner of stainless steel tubes 4b which form the chamber 5. The core section inside the watercooled tubular polarizing windings 2 is increased by the addition of laminated bars 3 made of steel strips held together by " Araldite " (Registered Trade Mark). An insulating joint 12 of the same material may close the accelerator gap in tube 5. The core frames are arranged in four sets of five pairs separated by cooling gaps 17 and are formed of ferrite bars held together by clamping means (Fig. 5, not shown). The two symmetrically arranged polarizing windings 2 are twisted in the form of an 8 to prevent coupling of the high frequency of the accelerating field with the lowfrequency polarizing circuit. The polarizing circuit may be provided with a filtering device outside the cavity.

Abstract: 1474517 Automatic control of flow DRESSER EUROPE SA 3 May 1974 [3 May 1973] 21138/73 Heading G3R [Also in Division G4]  In a blending and dispensing pump having liquid fuel lines 1, 2 which carry low and high octane fuel to a mixing valve 3 and outlet 4, each line has a respective generator 5, 6 producing a pulse for each unit (e.g. À005 gallons) of fuel dispensed and the generators are connected to the inputs 10, 12 of an up-down counter 11, one connection being via a pulse rate adjuster 8 and the counter output being used as an error signal to control the valve 3 via a servomechanism 14 to reduce the error signal to zero. As shown the adjuster 8 is a divider having a divide ratio set by a unit 7 when the desired blend is selected. This unit also delivers a unit price signal to a display 17 and to a multiplier 20. The pulse trains from the generators 5, 6 are combined at 19 to give a signal indicative of the total fuel volume dispensed, this being displayed at 15 via a cumulative counter 18. The volume signal is also fed to the multiplier 20 and multiplied by the unit price signal to feed a total dispensed price display 16 via a counter 21. The displays are of electromechanical or seven-segment solid state type. A more complex alternative embodiment is described in which a frequency multiplier (23), Fig. 2 (not shown) is used instead of a divider, and the volume and price of fuel dispensed are stored as a continuously recycled and updated binary data word. The word also contains information of remaining credit if fuel is to be dispensed to a preset price, and signals are derived to slow down and stop the pump motors as credit is nearly and then totally exhausted (see Division G4).
