Title: Metal Plated Plastics and process therefor
IPC: C23C18/16
Filed: 1967-03-10
Abstract: 1,180,583. Treating polyolefins. UNION CARBIDE CORP. 10 March, 1967 [10 March, 1966], No. 11345/67. Heading C3P. [Also in Division C7] Metal-plated plastics material whose coatings are strongly adherent, with peel strengths of 5 lb./in. or more are produced by oxidizing the surface of an at least partially crystalline aliphatic poly-α-olefin containing tertiary hydrogen in the aliphatic side chain and plating it with metal, preferably by electroless deposition. The aliphatic poly-α-olefin is preferably characterized by the general repeating unit wherein R 1  and R 2  are alkyl groups and x is 0 or 1, and has an open crystalline structure and a high melting point, with little difference, between the densities of the material in crystalline and amorphous forms. These properties are believed to be related to the strong adhesion obtained between such plastics materials and applied metal films. Poly-(3-methylbutene- 1), poly-(4-methylpentene-1) and poly-(4-methylhexene-l) are examples of suitable poly-α-olefins. Substrates of these materials may be oxidized in chromic acid, or in a mixture of chromic acid with a mineral acid, in either case with water. Alternatively flame treatment, corona discharge, glow discharge, ozonation or exposure to actinic radiation may be employed. The substrate is subsequently sensitized in a solution of stannous chloride or other reducing agent, then immersed in a solution of a salt of a noble metal such as platinum, palladium, silver or gold, a halide such as palladium chloride being preferred. Alternatively an initial metal film can be deposited by a spray-gun, by decomposition of metal carbonyls by cathode sputtering or by vacuum metallizing. The substrate so prepared is immersed in an electroless plating solution and copper, nickel or other metal deposited, then further metal, e.g. Cu, Ni or Cr is deposited by electroplating until the metal film reaches its final desired thickness. Metalplated polyolefins according to the invention are stated to be useful as knobs, handles, &c. and in applications including exposure to elevated temperatures, as in plumbing fixtures, printed circuits intended to be used at high temperatures, reflectors, &c.

Title: Improvements in or relating to flotation gear for aircraft
IPC: B64C35/00
Filed: 1934-04-16
Abstract: 420,784. Emergency flotation gear. DAGNALL, R. F., 17, Stoke Road, Guildford, and LAMBERT, J. G., 12A, Granby Place, Leicester. April 16, 1934, No. 11383. [Class 4] [See also Group XXI] In flotation gear for aircraft comprising a pressure fluid container having a frangible closure which normally prevents escape of the fluid and a cutter automatically driven forward when the aircraft descends upon water to pierce the closure to permit gas to pass from the container to inflatable bags, a locking device is provided which operates automatically to prevent return of the cutter after it has pierced the closure. As shown, a cutter 20 is driven forward to pierce the frangible disc 19, on completion of an electrical circuit due to the aircraft descending upon water, by the explosion of a cartridge 17 which drives a plunger 32 forward shearing a fibre disc 35, which normally holds it in position by means of a screwed stem, and engaging a plunger 31 resting on the cutter 20. Gas passes along longitudinal recesses 27 in the cutter to an outlet 24 connected to the bags. Movement of the cutter is limited by the flange 28 and a screwed sleeve 29 normally engages the cutter which assists in supporting the disc 19. Holes 36 and channel 37 facilitate escape of air from under the plunger 32. A pawl 39 hinged to the plunger 31 and to a housing cylinder 30 engages with a spring- pressed pawl 42 pivoted in a chamber 44 and connected to an arm 46 to indicate when the cutter has been depressed. The disc 19 may be pierced manually, should the cartridge fail to explode, by means of a Bowden wire rotating a wheel 47 against the action nf a clock spring to cause a cam 48 to engage a follower 49 on the pawl. A projection 53 facilitates release of the pawl ; a cover for the chamber 44 and a rubber buffer 54 for the plunger 31 are pro. vided. A weakened portion of the container, e.g. a frangible disc of less strength than the disc 19, communicates with the atmosphere and is adapted to fail when the pressure in the container exceeds a predetermined value. Specification 410,489 is referred to.

Title: Improvements in amplifier circuits
IPC: H03F1/50
Filed: 1955-04-20
Abstract: 810,291. Electric analogue calculating. RADIO CORPORATION OF AMERICA. April 20, 1955 [April 23, 1954], No. 11444/55. Class 37. [Also in Group XL (c)] A television receiver (see Group XL (c)) comprises a video frequency amplifier the output of which increases according to an exponential function of frequency and an I.F. amplifier, the output of which varies inversely with an exponential function of the frequency of a modulation signal component. The I.F. amplifier comprises valves 251, 255 and 259 (Fig. 4), having coupling circuits with different resonant frequencies and of such Q values that the desired overall response is obtained. The response of the video amplifier is arranged to accord with the desired exponential function of frequency by deriving separately the terms of the exponential series The first term is derived by passing the video signal to the output circuit through amplifiers 267 and 269 having a level frequency response. The second term is derived by passing the signal through an amplifier 273 having an inductive lead the output of which is fed to an amplifier 275 having a level frequency response. Part of the output of amplifier 273 is squared by feeding it to two grids of a valve 287 to produce the third term and the final term is derived by multiplying the second and third terms. This is effected by feeding the two terms to two grids of valve 280. In an alternative circuit (Fig. 8), the video signal is fed to an amplifier valve 319. An output not dependent on frequency is obtained from the screen grid and fed to the control grid of a pentagrid valve 325 and an output having an amplitude proportional to frequency is taken from an inductive load 317 in anode circuit of the valve 319 and fed to two further grids of the pentagrid valve. The bias on the three grids is adjusted so that the components of the series are produced with such amplitude that the output has the desired frequency characteristic. It is suggested that the desired exponential frequency characteristic could alternatively be obtained by the use of stagger tuned circuits. In an alternative circuit (Figs. 6 and 7, not shown), part of the response characteristic of the I.F. amplifier is flat and only part varies inversely with an exponential function of frequency.

Filed: 1927-04-30
Abstract: 275,904. Bouillon, J. April 30, 1927. Detonator apparatus; track apparatus for actuating signals other than on, and for stopping, trains.-A track device 25 for stopping a train at a "danger" signal is associated with a wheeloperated circuit-closer for giving a warning signal, the two being moved together into and out of operative position in conjunction with the ordinary signal. The device 25 is adapted to operate an arm 26 controlling a valve to vent the trainpipe and apply the brakes, venting taking place through a horn 28. A sealed cock, not shown, is provided for the driver to close the vent after such operation. The device 25 is carried by a slidable bar 24 by which it is moved into or out of operative position. A treadle member 3 with convex upper surface is carried by a rod 4 resting on a counterbalanced lever 16, the inner end of the rod sliding in a sleeve 5 and having pins 8 projecting through slots in the sleeve into engagement with forks 10 carried by a nut movable, without rotation, along a threaded shaft 12. Shaft 12 is rotated a limited amount in one direction or the other through gearing 13 from a motor 14 energized in conjunction with operation of the ordinary signal. The nut is also connected to bar 24. The inner end of sleeve 5 is mounted by a ball-joint 6. Member 3 can thus be moved to and away from the rail 21, and can also be rocked and depressed by the wheel 22 of a passing vehicle, the depression serving to close contacts 17, 18 of a signal circuit by depression of lever 16, so operating a suitable signal such as a searchlight, beacon, rocket, or electric horn. Member 3 has two projections 20 which engage under the head of the rail 21 to limit its upward movement. The rocking action of member 3 as it is depressed by a passing vehicle lessens the shock of impact without the use of springs. A detonator 23 may be clipped to member 3 so as to be placed on the rail when said member is in the "danger" position, thus giving a warning independent of the closure of contacts 17, 18. The motor and gearing may be omitted and the rod 24 operated by pull rope.

Abstract: 527,983. Weighing-apparatus. BEST, C., and MOLINS MACHINE CO., Ltd. April 21, 1939, No. 12049. [Class 143] In a weighing-apparatus suitable for weighing single cigarettes, the scale beam or other swing- ing member is secured, for oscillating movement, upon a tensioned thread-like or strip-like element and the beam is provided with lugs surrounding the tensioned element and extending loosely into holes for the purpose of preventing strain on the tensioned element in the event of accidental knocks. As shown in Fig. 2, the beam 1 is secured by clamping plates 18 to a wire 3 fastened at one end by a clamp 17 and, after passing round a pulley 19, attached at the other end to a clamp 20 connected to a tension spring 21. The tension of the wire is adjusted by a nut 122 and screw 120 acting through the spring. The clamps 18 besides clamping the wire 3, hold also tubular lugs 4 (or are formed integral with halves of the tubular lugs) surrounding the wire and located partly within holes 5 in brackets 6. Should the beam or wire be accidentally knocked, the lugs prevent damage. During assembly of the apparatus, the brackets 6 are slid towards the beam so as to engage larger portions of the lugs to facilitate initial aligning and tensioning of the wire. The wire may pass over knife-edged V-notches in plates adjustable on the supports 2. The beam is arranged to give a zero indication when a cigarette of correct nominal weight is being weighed. If cigarettes of a different nominal weight are to be weighed, a micrometer nut 11 connected to the beam by a spring 9 is adjusted to effect the change. In a modification, the change is effected by imparting a twist to the wire by means of a graduated dial at the ends of the wire. Temperature variations, compensating for.- Variations of the spring 9 due to changes of temperature are compensated for by a bimetallic strip 22, Fig 7, interposed between the adjusting screw 10 and the spring.
