Title: Support arrangement for a suspended ceiling beneath a structural ceiling
IPC: E04B9/14
Filed: 1974-11-05
Abstract: 1485286 Suspended ceilings A HENGGELER and R CROTTAZ 5 Nov 1974 [15 Nov 1973] 47861/74 Heading E1W A support arrangement for a suspended ceiling comprises suspension components 4 connected with support members 1 for ceiling slabs at a distance from the intersection points of a grid arrangement of members 1, connected with one another at their ends by intersection elements 2, and areas enabling adjustment of each suspension component 4 in three directions x, y, z independently of the other suspension components. The suspension components comprise threaded bolts 4, 16 engaging elongate slots 13 in brackets 11, 12. The support members 1 abut arms 3 of the intersection elements 2 with elastic buffers 31 interposed. Gaps between adjacent arms 3 enable ceiling slabs to be supported at their corners by the intersection elements 2 as well as being supported at their sides by the support members 1. Holes 37, 38 in the connection plates 2 and support members 1 enable the attachment of electrical fittings, and when not in use the holes are sealed by plugs.

Title: Hydropneumatic suspension unit for'ehicles
IPC: B60G17/044
Filed: 1971-10-15
Abstract: 1409875 Self-pumping self-levelling systems GIRLING Ltd 10 Oct 1972 [15 Oct 1971] 47983/71 Heading F2S A hydropneumatic self-pumping self-levelling suspension unit or system for a vehicle, in which the load is supported by gas in a pressure chamber, the volume of gas being variable in accordance with the load by liquid drawn from a reservoir 7, has a pressure relief valve 41-44 which is normally closed but opens to place the pressure chamber in communication with the reservoir 7 when the pressure within the pressure chamber exceeds a predetermined value because of a sudden shock loading. The pressure relief valve is required to be a plurality of valve members 42 held on to their seats 43 by an annular washer 44. The load-bearing pressure chamber (not shown) may be inside the unit, or outside the unit and connected to it by a union 36. During the normal levelling operation with the unit contracted under increased load to less than its mean length and the piston 17 covering a levelling port 40, liquid is pumped from the reservoir 7 via a valve 29 into a hollow piston-rod chamber 16 (on downward movements of the piston) and from the chamber 16 via a valve 33 (on upward movements of the piston) into the chamber above the piston and into a chamber 34 which is in communication with the load-bearing pressure chamber. As the piston oscillates pumping continues until sufficient liquid has been pumped from the reservoir 7 to the pressure chamber to force the piston down until the unit is extended to its mean length, and the piston uncovers the levelling part 40 to allow flow back from the pressure chamber to the reservoir 7 and prevent further extension of the unit. However in the event of a sudden shock loading the pressure in the pressure chamber opens the pressure relief valve 41-44 and allows liquid to flood back into the reservoir 7.

Patent GB-1484325-A (GB)
Title: Polymer dispersions
IPC: C08G63/00
Filed: 1974-11-07
Abstract: Aqueous dispersions of air-drying alkyd resins which have been modified by means of drying fatty acids are prepared by carrying out the dispersal in the presence of combinations of nonionic and ionic emulsifiers. The hydrophobic part of the emulsifiers comprises radicals of unsaturated fatty acids or fatty alcohols, which causes chemical incorporation during film formation. The nonionic emulsifiers contain polyethylene glycol chains, and the ionic emulsifiers contain carboxyl groups. Emulsifiers of this type allow a significant reduction in the polyethylene glycol content in the dispersions, which results in an improvement in the resultant paint films, in particular with respect to water resistance.

Abstract: 1372115 Paper made from synthetic polymer fibrils GULF RESEARCH & DEVELOPMENT CO 27 Oct 1972 [29 Oct 1971] 49680/72 Heading D2B [Also in Division B5] Fibrils having a length of 1-5mm and a diameter of 10 to 30 microns for use in papermaking and comprising a linear polyethylene having a high melt load index (ASTM Test No. D 1238-65T, condition F) of less than 0.25g/10 min and 5 to 50% by weight of an encapsulated filler material are prepared by dissolving the polyethylene in a high boiling point hydrocarbon solvent at an elevated temperature, dispersing and suspending finely divided particles of an insoluble filler material in the polymer solution in an amount of 5 to 50% by weight based on the total solids weight, forming fibrils from the resultant mixture by a suitable solution spinning technique (e.g. centrifugal spinning), and washing and refining the filled fibrils. In Examples filled fibrils are prepared from a suitable polyethylene by dissolving the polymer at 150‹C in a hydrocarbon solvent having a boiling range of 155-180‹C or 180-200‹C, dispersing silica calcium carbonate, titanium dioxide or kaolin clay particles in the polymer solution by stirring and spinning the resultant mixture. Paper sheets were prepared from the filled fibrils by forming an aqueous slurry of the fibrils together with a surfactant, charging the slurry into the head box of a sheet-forming machine, diluting the slurry with approximately 5 volumes of water, forming paper sheets from the slurry by the normal methods and drying the sheets.

Abstract: 1282320 Aerials HOLLANDSE SIGNAALAPPARATEN NV 13 Oct 1969 [13 Oct 1968] 50222/69 Heading H4A An aerial system comprises a plurality of linear arrays of radiators and a transmission line network coupled thereto. The network has a plurality of transmission lines for signals in respective different frequency bands, and a respective frequency-selective coupling arrangement coupling each array to each line only at the frequency band associated with that line. As described, an aerial 1 comprises four linear slotted waveguides 3, 4, 5, 6 which are disposed in parallel with their slotted faces co-planar. One end of each waveguide is terminated in a non-reflecting load 14 and the other end is connected to a first port of a respective diplexer 9, 10, 11, 12. A supply line 7 operating in a frequency band I is connected to a second port of each diplexer through respective directional couplers 22, 23, 24, 25 and a supply line 8 operating in a frequency band II is connected to a third port of each diplexer through respective directional couplers 22<SP>1</SP>, 23<SP>1</SP>, 24<SP>1</SP>, 25<SP>1</SP>. The far ends of the lines 7, 8 and the fourth ports of the diplexers are terminated in non-reflecting loads (15, 16 and 21, respectively). Each diplexer 9, 10, 11, 12 comprises two filters 20, 20<SP>1</SP>, passing only the frequency band II, on each side of which are directional couplers 19, 19<SP>1</SP> in the form of short-slot hybrids. When transmitting, the diplexers combine power of each frequency band into each linear array and, when receiving, the diplexers separate power of each frequency band into the appropriate supply line. The shape of the radiated beam for each frequency band may be controlled by adjusting the lengths of the appropriate supply line between consecutive directional couplers, and the coupling factors of said couplers. For example, a cosecsquared shaped beam may be used for signals of frequency band I and a pencil shaped beam for signals of frequency band II. The said pencil shaped beam may be scanned by varying the frequency of the signals to the supply line 8, and the dispersion of said line may be increased by making it of serpentine form. Dispersion in the supply line 7 may be compensated by means of phase-shifters 26.
