Abstract: 1,226,862. Adhesive coatings. BREVETEAM S.A. 14 Feb., 1968 [22 Feb., 1967], No. 7301/ 68. Heading B2E. [Also in Division C3] A floor covering material comprises a textile floor cover base having a layer of an adhesive composition (see C3 Division abridgment) applied to the reverse side thereof. The composition is pressure sensitive at room temperature so as to be held to a floor surface with adhesive forces when pressed in contact therewith, the composition having a cohesion at room temperature greater than such adhesive forces whereby after pressing the composition in contact with the floor, the covering material can be removed without separation of the composition occurring. The composition is softenable at 60-100‹C so as to adhere to a floor surface with greater adhesive forces than those formed by room temperature pressure adhesion. The composition may be applied in a hot melt state to the textile floor covering base and cooled. The exemplified composition comprises a mixture of polyterpene and polyester resins blended with a mixture of an ethylene-vinyl acetate copolymer and a polyisobutylene.

Abstract: 1,227,359. Shock absorbers. INTEGRATED DYNAMICS Inc. 1 April, 1968, No. 15479/68. Heading F2S. A stack of circular discs 7 of resilient material such as rubber or plastics is located in a housing 8 and capped by a plunger 4 to constitute a shock-absorber. Each disc is required to have a peripheral cavity 12 of parabolic form and the discs are required to be in direct contact with each other. Thus, in the unloaded state of the shock-absorber the only contacts between the housing and the discs are circumferentially extending line contacts. Preferably the size of each cavity is such that, at the maximum compressive loading within the elastic limit, the spread of elastic material into the cavity is less than the volume of the cavity in the unstressed state: i.e. the peripheral wall of each disc never becomes convex. The discs may be of different materials and the sizes of the cavities in successive discs may be different as shown. The plunger, the discs and the housing wall may have respective apertures 20, 21, 22 to allow for air to flow in and out as the plunger reciprocates. In the construction shown the shock absorber is effective in compressive loading only, but by bonding the discs to each other and to the housing base 3 and the plunger head 5 it could be made effective in tension also. In Fig. 3 (not shown), means are provided for adjustably precompressing the stack of discs.

Abstract: 1,232,633. Moulding corrugated tubing. DART INDUSTRIES Inc. 8 May, 1968 [8 May, 1967], No. 21879/68. Heading B5A. Apparatus for the continuous production of corrugated tubing by blow-forming extruded tubing is essentially similar to that described in Specification 1,124,071 with the addition of a pair of vertically reciprocable knives 40, Figs. 1 and 5, and associated tube clamps 16, so arranged that predetermined lengths of tubing are cut-off without the release of the blowforming pressure within the tubing upstream of the knives. Each clamp 16 comprises a fixed half 20 and a half 26 retractable by means of a fluid-actuated cylinder 60. The halves 20, 26 have cavities 22, 24 which may or may not be internally configured in correspondence with the blown tube. If the cavities are smooth the tubing is subjected to a compressive force. Each knife 40 passes through slots in the top and bottom of its associated clamp 16, see dotted line (50) position, Fig. 4 (not reproduced), and the faces of the knife blade seal the cut ends of the tubing. In operation, Fig. 5, knife 40 at station C is lowered followed by lowering of knife 40 at station B. With the latter knife remaining lowered, knife 40 may be raised at station C with associated clamp 16 being opened. The cut end of the tubing is removed from this clamp and the upstream portion of the tubing is looped and placed therein, Fig. 7 (not shown). The knife 40 at station C is now lowered and that at station B raised with release of associated clamp 16 and removal of tube length 66. The process is continued in a similar manner, Figs. 8 and 9 (not shown).

Abstract: 1,252,001. Reciprocatory fluid motors. BUTTERWORTH HYDRAULIC DEVELOPMENTS Ltd. Jan. 28, 1969 [Feb. 12, 1968], No. 6795/68. Headings F1A, F1P and F1S. In a fluid-pressure operated reciprocatory motor a piston 1 reciprocates continuously or intermittently within a cylinder 2 and a spool 16 disposed radially thereto is actuated by a.cam surface 18 provided on the piston 1 to move in a cylinder 15 which opens into the piston cylinder 2 and wherein thrust means is located between the piston and its cylinder to oppose the radial force applied by the spool 16. The thrust means comprises a hydrostatic bearing recess 23 in communication with a constant pressure chamber 6 to provide a hydraulic pad to counteract the bias provided by the spool 16 on the piston 1. In a modification Fig. 3 (not shown) the hydraulic pad 23 is formed as a port annular recess (24) in the cylinder 2 and is in communication with the chamber 6 via a channel (25). The chamber 8 is alternately supplied with hydraulic pressure fluid and connected to exhaust via the port 14. The constant pressure chamber 6 is connected to a chamber 20 which biases the spool 16 for abutment of the follower 19 which may be a sphere, cylindrical roller, or needle bearing, with the cam surface 18. In operation the shaft 17 may be fixed to a framework and the shaft 4 to a tool so that the body 3 will reciprocate on the shaft 17 and hence impart a compound motion to the shaft 4.

Abstract: 1,264,441. Gas analysis. BECKMAN INSTRUMENTS Inc. Oct. 20, 1970 [Dec. 15, 1969], No. 49716/70. Headings G1B and G1N. To determine the nitric oxide or total nitric oxide and nitrogen dioxide content of a sample gas stream, the nitric oxide is oxidized to nitrogen dioxide by reaction with at least the stoichiometric amount of ozone, the resulting gas stream being scrubbed or treated to remove residual ozone, and the nitrogen dioxide content determined to provide a measure of the nitric oxide or total nitric oxide and nitrogen dioxide content of the sample gas stream. As shown, the sample gas stream passes through a scrubber 54 to remove gases which would interfere with the nitrogen dioxide analysis, such as sulphur dioxide, halogens, hydrogen sulphide, and mercaptans and, in the case of a nitric oxide measurement, nitrogen dioxide, and thence to a reaction chamber 32 where the nitric oxide is reacted with ozone. The ozone source 44 may comprise a tank of liquid ozone, or an air stream cleaned by passing over activated charcoal in a scrubber 46 and passed through ozone generating apparatus 48 using electric discharge or ultraviolet radiation. Gas from the reaction chamber 32 passes through a scrubber 34 containing silver oxide to remove ozone, or is heated to at least 200 C, to decompose the ozone, and passed to a nitrogen dioxide analyser 36. The scrubber 54 may contain calcium or potassium hydroxides. The analyser 36 may comprise a colorimetric instrument of known type, but is preferably a galvanic cell containing an aqueous halide electrolyte with a cathode of inert conductive material, e. g. platinum or graphite, and an anode of active carbon, calomel, or silver chloride. The nitrogen dioxide dissolves in the electrolyte and the current generated by the cell is a function of the rate of entry of the nitrogen dioxide into the cell. An amplifier and meter or recorder provide a continuous visual indication of the current output of the cell.

Abstract: 1,264,659. Pseudo stereophonic systems. R. A. ORBAN. 3 April, 1969, No. 17437/69. Heading H4R. In apparatus for producing a pseudo stereophonic effect from a monophonic signal, the monophonic signal is fed through a phaseshifting circuit to produce phase changes at a number of different points in the frequency spectrum and the phase-shifted signal is added to the original signal to provide one stereo channel and subtracted from the original signal to provide the other stereo channel. Fig. 2a shows the phase-shifting circuit in which incoming mono signals are fed via an emitter follower 22 to the inputs of a differential amplifier 24 via circuits causing different phase shift, being most effective in the 7 to 20 kHz region. A further phase shift circuit 34 is connected to the output of the differential amplifier to provide effective phase shift in the 2-7 kHz region, and the output from the phase shifter is fed via a Darlington emitter follower 28 to a second differential amplifier 30, with phase shifted inputs effective in the 30 to 100 Hz range, and the differential amplifier output feeds a phase shifter 36 effective in the range 100 to 2000 Hz. The resulting phase-shifted output is fed, together with the input signal from the emitter follower 22 to a matrixing circuit, Fig. 2b. The main input signal is fed direct to the two channels via common emitter amplifiers 44 and 46, one 44 having a higher gain and being provided with a balancing potentiometer 128 on its output. The phase-shifted signal is fed to a phase splitter 48 and the antiphase outputs added to the respective channel signals from amplifiers 44 and 46 to provide the L and R pseudo stereo signals.
