Patent GB-2042720-A (GB)
Title: Communication Apparatus
IPC: H04B10/2587
Filed: 1980-01-25
Abstract: A light transmitter includes a housing 10 arranged to receive sound through a mouthpiece 15, the sound vibrating a reflective member 11. The vibrating reflective member 11 modulates and reflects light from a light source 12 into a beam which is transmitted to a similar apparatus. A light sensitive device 18 for receiving modulated light from the other apparatus may be located within a sighting tube 16, the sighting tube being provided for aligning one apparatus with the other. In another embodiment, the light is modulated by a substantially transmissive member, the member vibrating in response to incident sound and thereby modulating the light. <IMAGE>

Title: Electric connector assembly
IPC: H01R13/622
Filed: 1980-03-27
Abstract: A connector assembly consists of an elastomeric insert member 14 held within a rigid shell 12 by a retaining ring 16 which engages both the shell and the insert. The assembly includes a passageway 56 between the insert member and the shell permitting access to the retaining ring to allow ready disengagement of the ring and insert from the shell using a suitable tool to radially move a portion 55 of the ring. Presently available connectors having mounting elements non-integral with the elastomeric insert occasionally come apart under mechanical abuse, but are usually difficult to disassemble for service, and are sometimes difficult to mate. The rigid shell which protects the insert from mechanical abuse and environmental conditions is adapted for mounting to panels 19 or to other supporting surfaces. Engagement of the ring with the shell is accomplished by radially movable retention means 55. The shell and insert may be sealed by an O-ring 68 which is arranged to allow entry of the disengaging tool. <IMAGE>

Title: Method for recovery of wastewater residues
IPC: D21H17/01
Filed: 1980-11-20
Abstract: A method for recovery of wastewater residues containing the activated sludge biomass, fibre and rind and recycling the recovered residues back to the main production process comprising the steps of treating the waste water residues with alkali solution having a concentration of 5-80 g/l on the Na2O basis at a temperature of 20-70 DEG C and dewatering, e.g. in a vacuum filter, the reaction mixture obtained, the alkali filtrate decanted containing the activated sludge alkali hydrolysis products being used to dissolve the melt in the course of preparing an alkali pulping liquor used in the main production process, and the dewatered alkali mass being added, in an amount of up to 40 percent by mass, to a fibred mass composition for the manufacture of cardboard and wood-fibre board. The alkali solution may be a white sulphate liquor. From a sump 1, waste activated sludge is forwarded to a mixer 2 to which sewage containing fibre and rind is also fed. The mixture is dewatered in a vacuum filter 3, and the filtrate decanted from the vacuum filter is forwarded for washing the pulp or discharged on the purification structures. The dewatered layer of the residue is placed in an agitator 4 where the alkali solution (on an Na2O basis) is added. Liquid and solid phases are finally obtained from a second vacuum filter 5. <IMAGE>

Patent GB-2092166-A (GB)
Title: GRP Mouldings of Low Resistivity
IPC: C08K5/521
Filed: 1982-01-13
Abstract: A plastics resin suitable for use with glass fibre to produce a GRP material includes tri-beta- chloroethyl phosphate (TCEP) and greater than 4.5% carbon black. The carbon black decreases the resistivity of the resin so inhibiting the build-up of static electrical charge on the surface of an article made from the resin. The TCEP increases the fire retardancy of the resin, and reduces the viscosity, making the resin easier to use in the moulding process.

Patent GB-2105685-A (GB)
Title: Packages for liquids
Inventor: BILLBERG ALF
IPC: B31B50/20
Filed: 1982-07-30
Abstract: Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be "dovetailed" into one another. A packing container blank is provided with partly straight, parallel lateral edges (11,12), and partly transverse edges (11,12) which are indented according to a regular pattern which is repeated over the width of the blank. As a result of the indentations, the edges of the blanks too can be formed without wastage.

Title: Rotary to reciprocating crank/lever drive
Inventor: REIHLE MARKUS
IPC: B30B1/14
Filed: 1982-10-27
Abstract: A lever/connecting rod drive for plungers of presses in which during the working stroke the plunger speed is reduced to zero to engage stationary masses which subsequently have to be accelerated, wherein the connecting rod (9) in the region (c) of engagement of the plunger (11) with the stationary mass passes in the coupling curve (14) of the lever drive through at least two successive points (a, b) which coincide or nearly coincide with the instantaneous connecting rod to plunger pivot radius (r) in order to produce a speed of zero or nearly zero (Fig. 1 and Fig. 2). This achieves the result that shortly before reaching the mass the plunger is decelerated to zero or nearly zero. It thus gently engages the mass, subsequently accelerating the mass from zero. <IMAGE>

Title: Method and device for connecting sidewalls when cardboard blanks are formed into trays
Inventor: SCHABERGER CARLO
IPC: B31B1/60
Filed: 1983-04-22
Abstract: In the formation of trays (such as are used as pallet carton false bottoms or intermediate layers) from cardboard blanks, two juxtaposed end portions of two side walls, that are swung up perpendicularly to the base and are to be connected together, have parts thereof punched out and bent over in one and the same operation by a single penetrating tool provided on a piston rod head (2) of a fixed-position hydraulic pressure cylinder. The two juxtaposed parts are punched out by a blade (1) which may produce a straight or serrated cut, and rows of spikes (3) which produce interrupted cutlines, or further straight or serrated blades, and are subsequently bent over by means of ejector bolts (4) and remain interengaged in their bent orientation. Thus, cardboard blanks which only have slits at their corners may be used in place of expensive blanks which have their corners pre-cut in a special shape for subsequent interlocking. <IMAGE>

Patent GB-2161026-A (GB)
Title: Antenna arrangements
Inventor: BROWN ANTHONY KEITH
IPC: H01Q3/01
Filed: 1984-06-29
Abstract: An antenna arrangement is described for receiving transmissions on a ship, or other mobile, from a geostationary satellite or the like, and includes means for compensating for multi-path interference caused by reflection from the sea. The arrangement has two antenna elements 20,22 which are mounted on a screw-jack arrangement 40 which can be adjusted by a motor 42 so as to alter the separation D. This varies the position of the nulls in the response of the elements. Separation D is adjusted according to the geographical position of the ship relative to the satellite so as to position a null in line with the path of the reflected signal. In order to provide additional compensation for the instantaneous changes in attitude of the ship due to the motion of the sea, a phase shifter 34 is provided. This is adjusted by transducers sensitive to the ship's attitude and thus alters the angle of the response of the antenna arrangement relative to the two elements 20,22. The phase shifter 34 may advantageously be adjusted by a closed-loop feedback arrangement which monitors the received signal and produces a correction signal dependent on any fading. <IMAGE>
