Abstract: 944,707. Acoustic tiles. WOOD CONVERSION CO. Oct. 21, 1960, No. 36233/60. Drawings to Specification. Heading B6G. [Also in Division B3] Porous bodied tile is converted to acoustic tile by forming fissure-like openings and soundabsorbing holes into but not through the tile from the exposable face, and by creating a visual contrast between said face and fissures by application of material to the exposed areas of the fissures and/or of said face of the tile, said face being then substantially non-porous and presenting a substantially monochrome surface in white light reflectance. The material of the tile may be a porous mass of bonded mineral granules, or a bonded or unbonded felt of vegetable fibres or of natural or manufactured mineral fibres e.g. amosite, mineral wool, glass fibres. The latter being brittle, require a bonding agent such as starch grains. The walls of the fissures may be sprayed at an angle with colour, or opposite walls sprayed with different colours. It is preferred that the face be coated after any coating of the fissure walls thus covering any colour spilled over on to the face during the coating of the fissure walls. The fissures may be formed by sand-blasting through a stencil (this method producing an undercut fissure wall) or by a routing bit, punch or cutting die. Sound absorbing holes may be produced by punching or drilling. An arrangement for continuous production of the tiles is described. Specification 944,706 is referred to.

Title: Improvements in and relating to process control systems embodying polarimeters
Inventor: GILLHAM ERIC JOHN
IPC: G01J4/04
Filed: 1956-11-29
Abstract: 882,244. Photo-electron analysis. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 29, 1957 [Nov. 29, 1956], No. 36590/56. Class 40(3). [Also in Group XX] A process control system uses a polarimeter in which the plane of polarization of a light beam is oscillated about the position for extinction, when no specimen is present, by using the Faraday effect, and the rotation produced by the specimen is evaluated from the component of light transmitted at the frequency of the oscillation and incident on a photo-cell, the signal from which is applied to the control of the process. As shown, monochromatic light from a lamp 1 and filter 6 is collimated by lenses 2 and 3 and plane polarised at 7 before passing through a Faraday device consisting of a transparent rod 8 surrounded by a wire coil 11, a specimen cell 23, and a similar Faraday device 24 to a crossed analyser 14 and thence to a photo-cell 16. The axial magnetic field in rod 8 due to the application of alternating current to coil 11 oscillates the plane of polarisation of the light beam about the extinction position, and the plane of polarisation is also rotated by the specimen in the test cell. The component of the photo-cell output having the frequency of the alternating current is filtered out and applied to an indicator and also to the control of a process involving the sample in cell 23. In order to find the rotary power of a solution which may flow through cell 23, a direct current is applied to the Faraday device 24 so as to produce a rotation of the plane of polarisation opposite to that introduced by the specimen and resistance is adjusted until indicator reads zero. Faraday device 24 may be omitted in which case a variable direct current may also be applied to the winding 11 for the same purpose. So that a constant watch may be kept on the specimen, the output from -a photo-multiplier may be fed back through a recorder to the Faraday device 24 (Fig. 8, not shown). The output signal from the photo-cell may also be used to provide automatic control of a processing plant from which is derived the solution which flows through cell 23.

Abstract: 302,582. Elektrische Gl³hlampenfabrik Watt Akt.-Ges. Dec. 17, 1927, [Convention date]. Etching.-Relates to the process of frosting the inside of electric lamp bulbs and other hollow glass bodies, in which, after a first etching or matting operation, a second etching operation is performed to round off the sharp edges formed during the first operation, and consists in combining the two operations into one by the use of an etching medium rendered viscous by the addition of insoluble substances and applied to the glass surface in such a thin layer that the matting action ceases, but the rise in temperature due to the action causes the liberation by hydrolysis of agents which perform the second etching operation. A suitable etching medium consists of ammonium hydrogen fluoride, calcium chloride, water, hydrofluoric acid, and barium sulphate in stated proportions. External heat may be applied to assist the reaction.

Abstract: 627,794. Toys. LINES BROS., Ltd.. and LINES, W. Dec. 17, 1946, No. 37143. [Class 132 (iii)] In a toy comprising a figure mounted upon a support 3 and made up of blocks 1 strung together on cords 2, the lower ends of the cords are anchored to lugs 5, Fig. 2, of a cupshaped base 4, the base 4 fitting telescopically in support 3 and being spaced therefrom by a rubber cylinder 6 which normally serves to hold the cords under tension and which incorporates a sound producing device comprising a reed 9. By applying manual pressure to the base 4, the cords are relaxed and the figure assumes various postures while at the same time a noise is produced by expulsion of air past the reed 9. On release of pressure the base is returned to its initial position by the resiliency of the cylinder 6. The reed may be so arranged that the noise is produced as the cylinder is restored to its initial shape. In a modification the cylinder 6 is open at the bottom and makes airtight contact with the base 4. In a further modification the cords are held in tension by a spring or springs contained in a bellows mounted between the support and base, the bellows having an opening associated with a noise-producing device.

If however a connection to E1 is already established transistor T1 is cut off by the negative on its base so that P2 cannot operate. A holding circuit for P2 is obtained over its low resistance lefthand winding and resistance R1, the fall in potential over this resistance cutting off Tsp so that should E1 now attempt to set up a connection relay P1 will fail to draw current. Rectifiers such as G2 protect their associated transistors from induced surges when k2 opens the circuit for the left-hand coil of P2. Rectifiers such as GL2 prevent premature operation of P2 in series with transistor T1 and contact p1 at an instant occurring immediately after the de-energizing of P1. The arrangement may be used for connecting one of a number of markers to a register.

Abstract: 1,149,396. Cleaning and damping device; printing machines. AGFA-GEVAERT A.G. 19 Aug., 1966 [20 Aug., 1965], No. 37283/66. Heading B6C. A cleaning or damping device for the cylinders of rotary offset printing machines comprises a housing which is less wide than the axial length of the cylinders, a mounting means in the housing for a wiper band and means for attaching and detaching the device from the printing machine so that when the wiper band is in contact with a cylinder the device can be moved axially of the cylinder. Fig. 2 illustrates a device according to the invention in place on either the stencil cylinder 2 or the offset cylinder 3 of a duplicating machine. This machine is fitted with guide-bars 4 and 5, the bars being symmetrically placed axially of the cylinders which have the same diameter, bar 5 engaging a recess 6b in the housing 6 of the cleaning device, and bar 4 interacting with lug 6c preventing the device from falling into recess 3b in cylinder 3. The housing 6 can therefore pivot on these support means in a radial direction with respect to the cylinder and can slide axially across the cylinder, the width of the housing preferably being such that it can be grasped by hand (Fig. 1, not shown). As illustrated in Fig. 3, a winding spool 7 is attached to a milled rotary knob 8# and carries a wiper band 8 made of absorbent fabric or paper; a supply roll 10 is inserted in the housing 6 and its leading end is attached to the spool 7, a cover 9 is anchored to the housing 6 and the wiper band is kept under tension by means of a blade spring 13 and a roller 11 which acts as a brake. Between the roller 11 and the winding spool 7 are placed guide lugs 6g, (6h) and 6i which prevent the wiper band from deviating in a lateral direction as a result of the lateral wiping movement across a cylinder; a support 14 of resilient material, e.g. rubber or felt, is fixed behind the wiper band 8 in the section 6f of the housing, the curvature of which corresponds to the curvature of the printing machine cylinder. The means by which the wiper band is charged with liquid is also shown in Fig. 3; a resilient absorbent element 18, e.g. a block of foam or felt stands in the cleaning or damping agent 19 contained in a tray 16, the housing 6 being placed or pressed on top of element 18. The well cover 17 preferably contains a filling aperture 17a and side walls 17b and 17c confine the wiper band 8 and the side walls of the housing 6 thus substantially sealing the device and preventing evaporation of the cleaning or damping agent 19. When the device is in use, it is moved sideways on the machine cylinder until the whole of the cylinder has been in contact with the wiper band; when a section of the band becomes soiled, it is advanced by means of knob 8b until an unused section lies over the support 14. This section is then moistened using the tray 16.
