Abstract: 1,221,552. Laminates. HOLORIB Ltd. 7 May, 1969 [23 Sept., 1968], No. 45091/68. Heading B5N. [Also in Division E1] A building panel comprises a pair of spaced sheets 1, 2 a foamed plastics material filler 7 occupying the entire space between the sheets, being bonded thereto and defining the side edges 6 thereof, one of the sheets 5 extending beyond one side edge of the panel while the other 5 extends beyond the other side edge, the panel being such that when placed in edge-toedge relationship with another panel the sheet extensions of each panel overlap the adjacent panel and the foamed plastics filler material defining the panel sides abut. The panel may be made by clamping two of the sheets in faceto-face relationship with a strip of filler material extending along each edge of the panel to define with the sheets a space, injecting polyurethane material in liquid form into the space and constraining its expansion. The sheets may be of steel or aluminium and have a coating of a coloured plastics material, or may be of glass reinforced plastics material. The panels may be fixed together with riveting as at 10.

Title: Packaging
Inventor: DEREMER JAMES EGBERT
IPC: B65D25/24
Filed: 1963-11-15
Abstract: 997,138. Packaging; boxes. CONTINENTAL AVIATION & ENGINEERING CORPORATION. Nov. 15, 1963, No. 45131/63. Headings B8C and B8P. A method of packaging comprises introducing a rigid-setting liquid plastic foam into a container to form an article support therein, placing an article on this support when the plastic is in a condition to be moulded by the article, placing at least one parting element around or adjacent the article and introducing further rigid-setting plastic foam to fill the remaining space in the container and to cover the article while allowing a portion of the parting element to extend outside the plastic material. In a preferred embodiment the container is made of corrugated cardboard or weatherproof hardboard and comprises a base 10 provided with hollow legs 15 and corner posts 17 and a tubular sleeve 23 which is slid on to the base 10. The base is filled with liquid plastic foam such as polyurethane which enters legs 15, Fig. 8, through cut-outs in the base bottom to strengthen them sufficiently for stacking and fork-lifting operations. The article 18 is preferably enclosed in two complete wrappers 19, 20 of paper or the like and the parting element is a wire 21 which is wound round the article between the wrappers. The ends 22 of the wire are led out from wrapper 20 and are accessible after the article has been placed on the foam support and subsequently encased in foam either as shown in Fig. 4 or by attaching the ends to flaps 25 of sleeve 23. The surfaces of the container which contact the plastic foam are preferably waxed or otherwise treated to prevent adhesion of the foam although adhesion occurs between the foam and wrapper 20. To unpack the article, sleeve 23 is removed and the plastic foam is cut in two by pulling the wire outwardly and around the article. The wire may be heated to assist the cutting, Further embodiments provide channels between the legs 15 which communicate with the base bottom and reinforce the base when filled, an alternative opening device comprising two perforated sheets 34, Fig. 12, which when separated slice the foam block, and the packaging of an article between two polyethylene bags filled with liquid plastic foam (Fig. 10, not shown), also the foam may be allowed to adhere to the container and the wire arranged to cut the container and foam. The package, which is reusable and has a high buoyancy factor, may be weatherproofed by externally coating the container or by painting the foam block.

Title: Separation of lupulin from hops
IPC: C12C3/00
Filed: 1966-10-11
Abstract: A method of obtaining lupulin from hops comprises mixing the hops with an inert liquid, agitating the mixture and separating lupulin particles from the remainder of the mixture.  A slurry of fresh, dried, frozen or baled hops in water (weight ratio between 1:100 and 1:5) at a temperature within the range 1 DEG  - 20 DEG C. is agitated by paddles and stationary rods (44 and 50, Fig. 3 not shown) in a tank 10 and agitated slurry is pumped by a pump 56 through a conduit 60 to a vibrating screen separator 70 in which hop bracts, sprigs and other residual material are retained on the first screen 72 (10 - 100 mesh), and lupulin particles are held on and residual slurry passes through the second (or last) screen 72 (150 - 325 mesh).  The residual hop material and slurry are recycled to the tank together with make-up water, while the lupulin particles are recovered through a conduit 86.  In an alternative embodiment, the pump and rods serving the tank are dispensed with and the hop slurry passes through a tangential outlet 62 under the centrifugal force imposed by rotation of the paddles at speeds ranging from 100 to 1000 r.p.m.  A multi-bladed turbine-type paddle (46, Fig. 3 not shown) may be fitted in the tank to inhibit the formation of foam. <PICT:1104645/C6-C7/1>

In a digital data transmitter having a switching modulator 3 and a digital filter 5 as claimed in the parent Specification, the modulator can be switched to provide amplitude, frequency or phase-shift signals. The transmitter is as shown in the Figure. When switch 50 is on the rest contact 51 only gate 38 is enabled by carrier frequency pulses from 36, and the modulator provides a.m. signals. When the switch is on contact 52 the modulator acts as a modulo-2 adder and gives phase-shift signals. When the switch is on contact 53 a second carrier frequency is applied to gate 37, and the modulator gives frequency shift signals. The frequencies of the signals applied to the gates, to the data source 1, and to the shift register 7, are integral multiples of the frequency of the signal from generator 2.

The valve 35 is arranged to open when the associated reservoir is deflated by the diver inhaling the mixture therein whereas the valve 36 is arranged to open when the associated reservoir is inflated by the diver exhaling. The valve 36 includes a body 310, Fig. 3, which is attached to one wall of the reservoir 24 and carries an immovable looped or racquetshaped member 300, to prevent inward deflection of said wall, in addition to a similar member 304 upon a pivot 306, the latter member being engaged by the opposite wall of the reservoir so as to depress an axially-movable stem 308 on a valve-member (not shown) when the reservoir is deflected, thereby rendering the valve open. The valve is closed by the pressure of the mixture in the hose 26 acting upon said valvemember when the reservoir is inflated, outward movement of the wall adjacent the member 304 being accompanied by similar movement of the latter in response to displacement of the valvemember by the pressure aforesaid. The valve 42 is generally identical to the valve 36 save that it is rendered open by inflation of the associated reservoir. The reservoirs may be incorporated with a diving suit, which may be of the kind described in Specification 1,095,346.
