Title: Improvements relating to tips for cigarettes
IPC: A24D1/04
Filed: 1933-10-17
Abstract: Tips for cigarettes, for example of cork, ivory, imitation gold, pearl, or silk, are treated with a sterilizing-agent in such a manner as to be tasteless and odourless, and without substantial alteration in appearance.  Cork for use in tipping is passed through a chamber filled with formaldehyde vapour, then through a second chamber filled with ammonia vapour, and finally through a drying and ventilating chamber.  Instead of vapour, solutions of formaldehyde and ammonia may be used, the cork being heated in the third chamber.  Instead of the above substances, alcohols, phenols, ethers, aldehydes, ketones, hydrogen peroxide, or ozone may be used.  The cork may be treated in the block form, p  or in the strip form on its way either to the cigarette machine or the winding - machine.  The ammonia chamber may be omitted.

Title: Improvements in or relating to addressing and similar printing machines
IPC: B41L45/00
Filed: 1927-10-31
Abstract: 305,151. Schleifenheimer, G. Oct. 31, 1927. Sheet carriers and forwarders ; grippers and gripper mechanism.-In an addressing or similar printing machine, the sheets c to be printed as they emerge from feed-rollers e, Fig. 3, are seized by a gripper f and carried to an impression table a. The gripper is mounted on a reciprocating carriage g, and comprises a fixed jaw p, Fig. 4, and a spring-pressed jaw q. During the feed stroke, a pin s which is integral with the jaw q rides in a groove v and, at the end of the stroke, the pin moves into a parallel groove u so that the jaw is raised and the sheet is released. At this end, the groove v is deeper than the groove u so that the jaw q is also moved back. The jaw q is lowered at the end of the return stroke by a spring w. Delivery apparatus.-The sheets are delivered from the impression point by a second gripper k mounted on the carriage g and constructed and controlled in the same way as the gripper f. The sheets fall on to a table a, Fig. 6 and between vertical posts d. the table being periodically rotated through 90‹ so that consecutive sheets or batches of sheets may be separated. The table a is rotated by a cam c connected thereto by the posts d, and the cam c is rotated by a pawl 14, Fig. 5, on the end of a rod 13 pivoted to a crank-disc 12 rotated by a disc 11, which is periodically clutched to a rotary disc by a spring-pressed pin 9 when this is released by upward movement of an arm 7 caused by a pin 2 dropping into a notch 5 in one of a series of control discs 1 rotated at each impression by ratchet mechanism. The discs 1 have various numbers of notches according to the number of sheets to be collected in each batch. The table a is fixed by a screw b working in a stationary nut, so that as the table rotates it is gradually lowered. A cam 18 acts on a lever 4 to return the pin 2 and clutch to normal position. In another arrangement, Fig. 10 the number of sheets collected in each batch is controlled by notches in certain of the printing-plates. One of the racks a carries a pivoted lever b having a projection d pressed by a spring h into a notch g in a plate f when the rack moves to the right whereby a catch u on the opposite end of the lever b engages a shoulder i on a slide k when the rack returns to the left, and a lug l on the slide engages a pin m on a rocking-arm n and throws in a clutch for rotating the collecting- table a, Fig. 6. The arm n is held in that position by a lever r, which engages over a pin p on the arm n. On the next stroke to the left, the catch u engages a shoulder t on the lever r and rocks it out of engagement with the arm n unless the next address-plate also has a notch g.

Abstract: 816,650. Monitoring radio-frequency feeders. GENERAL ELECTRIC CO. Ltd., and EASTER, B. Oct. 10, 1955 [Oct. 8, 1954], No. 29080/54. Class 40 (5). A monitoring device comprises a transistor oscillator controlled so as to be active or inactive by a voltage whose magnitude is a function of the quantity to be monitored. In the embodiment described some of the radiofrequency power flowing in a coaxial feeder 3 is fed through a directional coupler 1 to a rectifier 2 which produces a unidirectional voltage across resistor 11 in the base circuit of a transistor oscillator 21. This voltage is backed off by the voltage produced across a resistor 13 by a local source. The oscillator operates, at a frequency, for example, of 5 kc/s., when the power in feeder 3 exceeds a predetermined value. Alternatively, the oscillator may be arranged to oscillate only when the feeder power is below a predetermined value. The power in a number of feeders may be remotely monitored over a single channel by a plurality of similar circuits feeding different frequencies which are separated at the receiving point by band-pass filters.

Title: Apparatus for extinguishing a chemical reaction in a nuclear reactor
Inventor: COSTES DIDIER
IPC: G21C9/04
Filed: 1963-07-23
Abstract: 965,403. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 23,1963 [Aug. 7, 1962], No. 29146/63. Heading G6C. Apparatus for extinguishing a chemical reaction in a nuclear reactor channel comprises a magazine for storage of a non-combustible material in divided form, connecting line means selectively operable to connect the magazine with a selected reactor channel, means for feeding said material from the magazine through the connecting line means to the selected channel, and means for retaining within the channel the material fed to it. The non-combustible material is in the form of solid particles such as grains or balls, and may comprise steel shot of a few millimeters diameter-the material is stored in a magazine 18, Fig. 2, which can communicate with feed hopper 20 through a gate valve 20. Gas-tight valves 24 and 28 allow the material to fan into chambers 26 and 30 which are respectively maintained at and above the pressure in the reactor vessel by means of gas conduits 32 and 34 and valves 33 and 35. The lower end of injector hopper 30 is provided with a feeder member 40 in the form of a rotating grooved pulley and is connected to the upper end of a tube 37 adapted to be connected to any selected reactor channel in a gas-tight manner, In the arrangement shown the tube 37 is extended by a director tube 38 movable within a scaled enclosure and adapted to be connected to any one of a number of tubes 44 connected to the coolant sampling tubes 12 of the reactor. A T-junction 46 in each tube 44 allows coolant gas to flow from the sampling tube 12 to monitoring apparatus 50. Each tube 12 communicates with a fuel channel and is preferably coiled tangentially around the channel and opens into the channel through an elongated port. When a fire (or abnormal chemical reaction) is detected the reactor is shut down and the coolant gas circulation rate is preferably reduced. A change of shot is then introduced into the affected channel and collects in a basket provided in the lower end of the channel. This retards the flow of gas through the channel and may be sufficient to check combustion. If the introduction of shot is continued, the height of the change of shot in the channel rises until it reaches the combustion zone. The mass of shot then asserts convection flow of gas around the fuel elements, cools the contents of the channel due to its high thermal inertia, and improves heat exchange by conduction through the mass of shot from the fuel elements to the sides of the channel. The mass of shot traps dangerous debris, facilitating subsequent decontamination,and retains fission products; the surface of the shot may be oxidised to facilitate bonding of fission products on it, and the shot may contain neutron absorbing material. After the depth of shot has reached a sufficient level the general circulation of coolant at normal rate may be resumed in order to cool down the core as a whole. Specification 869,539 is referred to.

Title: Improvements in and relating to soldering mechanism for can bodies
IPC: B23K1/16
Filed: 1935-10-23
Abstract: 464,771. Soldering can bodies. FARRER, J. O. (Continental Can Co., Inc.) Oct. 23, 1935, No. 29252. [Class 83 (iv)] In soldering side seams of can bodies 10, the bodies are fed along a roll rotating in a solder bath 2, the roll including a number of sections 7 of considerably less width than the length of the seam and mounted so as to yield independently to the contact of the can body. The solder roll will thus make uniform contact with the side seam, which may be concave due to heating of the body in the region of the side seam only. The bodies are fed by a chain 13 through an external horse 11. The solder roll consists of a series of rings 7 of greater internal diameter than the shaft 6 on which they are mounted, the shaft being driven by sprocket gear 4. The rings float in the molten solder and normally contact with the lower side of the shaft. When engaged by the body the rings are pressed down thereby and may contact with the shaft so that they are rotated therewith to bring the solder to the seam. The edges may be tapered to facilitate engagement with the body. The rings may be hollow and consist of U-shaped rings welded to rims or they may be solid and made of a metal or substance having a specific gravity less than the solder.

Abstract: 719,641. Ultrasonic couplings. KELVIN & HUGHES, Ltd. Dec. 12, 1952, [Dec. 13, 1951; Aug. 29, 1952], Nos. 29274/51 and 21830/52. Class 40 (4). [Also in Group XXXVIII] A method of testing thin sheet material by transmitting ultrasonic waves into the material at a small angle to the surface (see Group. XXXVIII) uses a liquid filled coupling means for materials such as copper where the usual solid couplers require an angle of incidence of the same order as the angle of refraction. The container 7 is provided with a spindle 8 which is rotatable in bushes 9 and one end of which projects through the side of the container and carries a pointer 10 which may co-operate with a scale, marked in degrees, on a circular plate 11. The pointer may also serve as a finger piece for turning the spindle 8. An insulated holder 12 secured to spindle 8 carries a piezo-electric crystal 13. Conductors (not shown) for the crystal 13 pass through an opening 14 provided with a screw-cap 15. A plug 16 is screwed into a hole through which the container 7 may be filled with a suitable liquid such as glycerine or oil. Using glycerine, and when the material to be tested is copper, an angle of refraction of 82 degrees is obtained with an angle of incidence of about 58 degrees.
