Title: Improvements in or relating to cylinders for internal combustion engines
IPC: F02F1/08
Filed: 1943-07-13
Abstract: 604,108. Valve gear. UNITED AIRCRAFT CORPORATION. July 13, 1943, No. 11400. Convention date, May 22, 1942. [Classes 7 (ii) and 7 (vi)] Inlet and exhaust valves 32, 30 are disposed on opposite sides of the cylinder 21 and actuated by rocker arms 54, 48 in boxes 56, 50 which overhang push-rods 74, 62 movable in guides 70, 58 which diverge from the crank-case 10, the rods being actuated by tappets 76, 64 contacting with cams 78, 66 in the crank-case. The push-rods are arranged substantially at right angles to the rocker arms. The invention facilitates the arrangement of rows of cylinders in a radial engine and cylinder strains are minimized by disposing the push-rods 74, 62 in a plane containing the cylinder axis. The symmetrical arrangement permits the cylinder to be mounted on the crank-case in either of two positions 180 degrees apart. Specifications 574,684 and 604,109 are referred to.

Title: Automatic printing machine
Inventor: GLATZ PAUL ALBERT
IPC: G03C1/725
Filed: 1965-03-17
Abstract: 1,083,384. Printing-apparatus. ROTAPRINT A.G. March 17, 1965, No. 11416/65. Heading B6C. An offset rotary printing machine comprises a control assembly including a plurality of control units I-V, Fig. 1b adapted to be driven by a motor 51 and arranged to rotate in either direction shafts 54 and 62, Fig. 3, which automatically control in a required sequence the movement of the various apparatus features into their operational position before printing and the tripping of the said apparatus features after printing. The motor drives a shaft 9 supporting cams 19-23 and, via gearing 11-13, a shaft 10 supporting cams 34-36, 39-41. The cams 19-23 move rockers 15 and according to the positions of microswitches 37 controlled by the cams 34-36, 39-41, solenoids 24 are energized and deenergized causing pulley and cable gear 47-50, Fig. 1b to be actuated. Actuation of cable 53 rotates the shaft 54 and operates means for rendering the printing plate more receptive to damping fluid, means for closing the plate cylinder grippers, and means for starting up the printing machine. A cam 34 energizes a solenoid in unit V so that a cable 59 is pulled and the shaft 54 rotated in the opposite direction, causing inking apparatus and the offset cylinder to be moved into their operative positions, after which the motor 51 is stopped. After printing the motor is re-started and the cam 36 in unit II stops the printing machine. The cam 41 causes the plate cylinder grippers to be opened and the plate is ejected when the machine is temporarily restarted. After washing of the offset cylinder the shaft 62 is reversed by the cam 35 and the cylinder is dried; unit II is briefly reactivated to pull cable 63 and stop the assembly and machine. The printing may be controlled by a programme card carrying marks indicating the sequence of printing of selected sections of the image, said card being advanced by stepping gear operated by pulses from a generator controlled by the revolutions of the impression cylinder or other means. The card stops if a sheet is incorrectly fed and the card is used to restart the motor 51 after printing. Alternatively the apparatus may be controlled by a counting device. A lamp 52 indicates when the shaft 9 is in its starting position.

Title: Improvements in or relating to composite kinematography
IPC: G03B15/10
Filed: 1941-09-08
Abstract: 553,197. Composite photographs on kinematograph films. TECHNICOLOR, Ltd., and GUNN, F. G. Sept. 8, 1941, No. 11469. [Class 98 (ii)] In the silhouette masking method of producing the composite photographs, the masks are made from two or more images of the foreground action against a plain backing, recorded in separate frames during each period of kinematograph analysis, the said images having different latent image characteristics obtained by varying the illumination of the backing, without varying that of the foreground action, during said period. The invention includes apparatus for carrying out the method, a form shown in Fig. 1 comprising a lamp b for illuminating the foreground a, lamps d for illuminating the plain backing c, and a camera system comprising an objective focusirig two images, by way of a beam-splitter j, respectively upon films A and B, a shutter e for normal kinematograph analysis, and a shutter f working synchronously with the lamps d so as to obscure the film A during changes of illumination. The light from the objective falls on film B during the whole period of exposure by the shutter e; but the backing c is illuminated by the lamps d only for the fraction of the whole period of exposure during which the shutter f obscures the film A. Thus the foreground action a is recorded on film A with an unexposed background area, and on the film B with an exposed background area. These films may be used for producing a pair of silhouette masks by developing both to negatives, printing positives therefrom, using the combination of the negative A superimposed on the positive from B to print a background mask, and then printing this mask to make its foreground silhouette component. In another form of apparatus, using the same camera system, the backing c is translucent and is illuminated from the rear by a lamp having a sector shutter syncronised with the camera so that the lamp illuminates the backing in the same way as the lamps d. Instead of using the beam-splitter j, the two or more exposures may be made in succession on a single film during the same period of kinematographic analysis by the shutter e, the camera mechanism being in this case driven at a rate faster than the normal. The masks may be rendered dense or opaque, as by dyeing their printed areas. The method may be applied to colour kinematography, in which case the mask may be printed from two superimposed images of the foreground in complementary colours, one developed as a positive and the other as a negative, using as printing light a colour or wavelength not transmitted by the dyes constituting the colour images. Specifications 374,849, 375,338, 484,698 and 500,721 are referred to.

Title: Improvements connected with the voltage control in parallel alternating current circuits
IPC: H02J3/38
Filed: 1927-05-04
Abstract: 295,231. English Electric Co., Ltd., and Ayres, W. E. M. May 4, 1927. Regulation, automatic. - Polyphase feeders 2, 3 connected in parallel to bus-bars 1 are associated with induction regulators 4, 5, the movements of which are co-ordinated so as to avoid circulating currents. Potential transformer 15 in the master feeder 2 operates a voltage relay 11 through a line drop compensator 19, to complete the circuit of either contactor coil 6 or 7 if the feeder voltage deviates from normal and so energize a pilot motor to adjust the regulator 4. A current transformer 22 feeds the compensator 19 and also one coil 24 of a balanced relav 14, the other coil 25 of which is fed from another current transformer 23 in the trailing feeder 3. If there is lack of balance of currents in the two feeders the relay 14 operates to energize either contactor coil 6 or 7 controlling a pitot motor used to adjust the regulator 5. An elaboration of the system is described which is applicable to any number of feeders and in which switching arrangements are incorporated so that any feeder can be made the master and the others the trailing ones. The normal voltage is adjusted by a resistance 20. Alternatively the co-ordination of the regulators 4, 5 can be effected by automatically moving the trailer to occupy a similar position to the master.

A carbon coating is produced over desired portions of the interior surface of an electron tube envelope by burning within the envelope a carbonaceous fuel deficient in oxygen, and thereafter burning off unwanted portions by a flame over-supplied with oxygen; the method permits the carbonization of the tube to be performed as one step of the process of sealing on the exhaust tubulation. The glass bulb 12 having a dome 30 and open end 24 is rotated about its axis while being indexed from station to station of a bulb tubulating machine, at the first of which the carbon coating is deposited by the introduction through end 24 of an air/acetylene gas burner. At subsequent stations, a soft and oxidizing flame polishes cut end 24 and burns off the carbon coating thereabout; a silicone rubber wiper is inserted into the bottom of the bulb to ensure complete removal of carbon; an air/hydrogen flame burns off the carbon coating on the dome 30 and preheats the latter, while an auxiliary burner preheats the lower end of exhaust tubulation 14; a needle flame punctures a hole in dome 30 and tubulation 14 is sealed thereto; the stem 16 with electron cage assembly 18 and barium getter 28 is sealed in the end 24 of the bulb; and the latter is exhausted before tubulation 14 is tipped off. Vertical movement of the burners within the bulb is sufficiently rapid to prevent the removal of the wall coating in a spiral track.
