Title: Polymerizable compositions for bonding articles and other purposes
IPC: C09J5/04
Filed: 1964-07-01
Abstract: A non-aqueous polymerizable system comprises at least two separate components one of which contains an ethylenically unsaturated monomer and a first compound and another of which consists of or contains a second compound, the one of the first and second compounds not being sulphur dioxide when the other is an organic hydroperoxide, the first and second compounds constituting the two parts of a redox catalyst system which when mixed causes at least 50% of the monomer to polymerize within 10 minutes at 50 DEG  C. or below. Suitable systems are t.-butyl hydroperoxide+ sulphuryl chloride, and ascaridole+sulphur dioxide. In addition at least one of the components may contain a polymer dispersed or dissolved therein such that polymerization may take place in the form of a film or by bonding particles together.  The invention also provides a method of bonding articles which comprises forming and allowing to polymerize between the articles a film containing the components of a non-aqueous polymerizable system, one of which components contains a monomer and a first compound and another of which components consists of or contains a second compound, the first and second compounds constituting the two parts of a redox catalyst system which on mixing causes at least 50% of the monomer to polymerize within 10 minutes at a temperature of 50 DEG  C. or below.  The second compound may be gaseous, e.g. sulphur dioxide, and may diffuse between the articles to be bonded.  In an example a resin containing epoxide groups was dissolved in a mixture of methylacrylate, methyl methacrylate and acrylic acid. t.-Butyl hydroperoxide was added and the composition was coated on steel panels. Sulphur dioxide gas was sprayed over the sufaces and the panels were joined.  The monomers polymerized whereafter the epoxide groups reacted with each other and with the active hydrogens of the polymer.ALSO:Articles are coated by forming and allowing to polymerize on the surface a film containing two components, the first component, comprising an ethylenically unsaturated monomer and a first compound and the second component comprising or consisting of a second compound, the two compounds constituting the two parts of a redox catalyst system which causes at least 50% of the monomer to polymerise within 10 minutes at 50 DEG C. or less.  In an example copper wire is passed through a composition comprising a copolymer of ethyl acrylate and methyl methacrylate dissolved in methylacrylate and ethylene glycol diacrylate containing ascanidole; and then into an atmosphere containing sulphur dioxide.

Title: Improved apparatus for producing bremsstrahlung radiation
Inventor: HANDEL NEIL EDWARD
IPC: G01N23/223
Filed: 1961-07-28
Abstract: 923,989. Determining thickness by radiation. INDUSTRIAL NUCLEONICS CORPORATION. July 28, 1961, No. 27569/61. Class 40 (3). [Also in Group XX] An apparatus for producing a beam of substantially pure bremsstrahlung radiation has a source which emits largely # radiation but some γ also, the radiation being directed at a target such that the γ rays pass through, but the # rays are mostly absorbed, the resulting bremsstrahlung being produced in a direction different from the direction of the γ rays. In the form shown in Fig. 3, a radiation source 36, for example krypton 85, is housed within a cavity 34a bored in a lead shielding block 34. A target 28 of sheet aluminium is placed at an inclined angle, as shown, supported in slots 40. (The construction is such that various targets 28 may be interchangeable). The γ rays pass through the target to be absorbed by an end wall 46. The bremsstrahlung beam passes out through a passage 42 bored at right-angles to cavity 34a. A thin stainless steel window 44 absorbs any # rays reflected from target 28. The beam of bremsstrahlung 20 emerging from the device can be utilized for any suitable purpose, as for example in thickness gauges, where it is passed through a strip of material to a detector on the other side. In the modification of Fig. 4 (not shown), the target 28 is affixed to the outside surface of the shielding block, the mixed radiation from the source being directed at it along one passage, and the "reflected" bremsstrahlung being directed down another passage at right-angles, the unwanted γ rays passing through the target and out of the device.

Abstract: 674,812. Typewriters &c. NATIONAL CASH REGISTER CO. Nov. 13, 1950 [Nov. 18, 1949], No. 27637/50. Class 100 (iv). Hammer impression arrangements.-A rebound dampening device for a printing hammer comprises a freely mounted member 30 co-axially pivoted with the hammer 13 so as to move with the hammer during the printing stroke and to damp the hammer movements on the rebound. The member 30 carries one or more removable weights 33 and is formed with two flanges 31, 32 bent at right-angles so as to embrace the edges of the hammer 13 but spaced so as to permit of relative movement between the hammer and the member 30. In operation a cam 28, through leverage and linkage 24-27, pivots anti-clockwise an operating lever 19 and the hammer 13 pivots likewise by the pull of a spring 16 on the arm 15 of the hammer 13 carrying a pin 20 which follows the end 19a of the lever 19. When the cam 28 passes its highest point a sudden clockwise movement is given to the lever 19 by a spring 21 and the end 19a operates the hammer 13. The plate 30 travels therewith, and after impact between the hammer and the type 10, continues to move forwardly and as the hammer rebounds it engages the flange 32 and its movement is damped by the weight of the member 30 so that a second impression due to retensioning of the spring 21 by excessive rebound is prevented. The member 30 is biassed by gravity into the position shown and the flanges 31, 32 are lined with shock and noise absorbing material 34. The operating lever 19 has a block 18 normally in cushioned contact with a stop 22 secured to a machine frame.

Title: Improvements in radio transmitters
IPC: H03H7/21
Filed: 1939-10-11
Abstract: 535,396. Wireless transmitting systems. LONGO, G. Oct. 11, 1939, No. 27677. Convention date, Oct. 11, 1938. [Classes 40 (iii) and 40 (v)] A transmitter comprises aerials A1 ... A4, Fig. 2, arranged in a circle, diametrically opposite aerials A1, A3 and also A2, A4 are energized in phase opposition with the carrier frequency suppressed. The modulating currents for the pair A1, A3 are in quadrature with the modulating currents for the pair A2, A4. An unmodulated carrier in quadrature with the suppressed carrier is radiated from a control aerial AO or from the four aerials in parallel. This method of radiation causes the instantaneous value of the energy radiated to equal the average value. Virtually the modulation rotates about the central aerial. If the modulating current be a single frequency f, the radial plane of maximum amplitude of the emitted wave rotates with an angular velocity 2#f, and the transmitter may be used as a beacon. Three or more pairs of circularly placed aerials may be used. The network, Fig. 3, enables two modulating currents in quadrature to each other to be derived from a complex audio current fed to the transformer T, these quadrature currents appearing respectively between terminals B<SP>1</SP>, B<SP>11</SP> and earth. In both the left and right banks the magnitude of the inductances and capacities are such that and the ratio of L1 or C1 of the left bank to L2 or C2 of the right bank is Á¢. Three or more banks may be used in the network to furnish polyphase instead of quadrature currents.
