A machine for wrapping bundles of articles, e.g. sausages, comprises conveyer means 1 for feeding the articles to movable transfer means 2 for transferring a bundle from the conveyer means 1 to elevator means 3 for raising the bundle to a wrapping station and means for securing and sealing the wrapping about the bundle, the transfer means being adapted to support the bundle during transfer without the necessity for a supporting card or tray. As shown, the conveyer means comprises a single chain 5 supporting slat elements (6) which may be of nylon or stainless steel and which support along the chain, flights 9 defining pockets 11 for individual bundles. The conveyer means discharges on to the transfer means 2 which comprises a pair of carriers 12 slidable on rods 13, each carrier being L-shaped and supporting a strip 14, the adjacent edges of the strips being provided with fingers 15. Each strip 14 is also associated with a wall 16 slidable relative thereto, and with a wall 18 pivoted to the strip. In use the carriers are inter-connected by a tiebar 19 for reciprocating sliding movement in unison by a driven shaft 26 through link 20, lever 21, follower 23 and a track 24 on a camwheel 25 fast with the shaft 26, which also effects pivotal movement of the walls 18. Bundles of articles in the pockets 11 are centralized prior to transfer to the strips 14 by a quadrant gear 43 also driven from the shaft 26. The conveyer 1 is indexed forwardly by an amount corresponding to the length of the pockets 11. The elevator means 3 comprises a pair of rams 35 and a two-part platform 36, one part 36a fixed to one ram and having fingers 37 which are in staggered relationship with fingers 15 and another part 36b fixed to the other ram, the arrangement being such that when a bundle is raised to a wrapping station (not shown), the bundle is supported by both parts, the part 36a thereafter being lowered to permit the wrapping operation prior to lowering of the part 36b. The wrapped bundle is discharged into a heat sealing station (not shown) comprising a pair of conveyer bands between which the wrapping is heated and subsequently cooled. The intermittent motion of the conveyer 1, plates 45, transfer means 2 and elevator means 3 are co-ordinated such that one bundle is indexed off the conveyer as the transfer means 2 is positioned adjacent thereto, the transfer means 2 is moved away from the conveyer and is then lifted to the wrapping station by the elevator means 3 which is subsequently lowered to allow the transfer means to move towards the conveyer to receive the next bundle therefrom.

Abstract: 1288688 Polyurethane foams FARBENFABRIKEN BAYER AG 17 Dec 1970 [17 Jan 1970] 59899/70 Headings C3C and C3R Polyurethane foams are prepared by reacting, in the presence of a blowing agent, a polyether polyol which has a M.W. of 750 to 10,000 and in which at least 10% of the hydroxyl groups are primary with an allophanate polyisocyanate which contains at least two NCO groups and at least one N,N<SP>1</SP>-disubstituted allophanate group and which is dissolved at a concentration of 10 to 70% by weight in one or more liquid polyisocyanates which do not contain allophanate groups. The polyether is suitably prepared by reacting a polyol or polyamine with an alkylene oxide and may be used in admixture with at least one other compound containing reactive hydrogen atoms. The allophanate polyisocyanates are suitably prepared by reacting N-substituted carbamic acid esters which may contain isocyanate groups with mono- and/or polyfunctional isocyanates. Suitably this is achieved by reacting in one stage a hydroxyl containing compound with excess polyisocyanate and heating the first formed reaction product at 100 to 160‹ C. to form the allophanate polyisocyanate which is dissolved in monomeric polyisocyanate if sufficient polyisocyanate has been added. Alternatively the allophanate polyisocyanate may be formed first and then dissolved in a monomeric polyisocyanate in a separate stage. In a typical example, a linear propylene glycol/ propylene oxide/ethylene oxide polyether, 1,4- butylene glycol, water and triethylene diamine are reacted with an isocyanate solution prepared by reacting 2,2-dimethylpropane-1,3-diol with a large excess of toluene-2,4- and -2,6-diisocyanates to first form the bis-carbamic acid ester diisocyanate dissolved in the monomeric diisocyanate which reaction mixture is then heated to 150‹C. to form a solution of allophanatepolyisocyanate in the monomeric diisocyanate. Uses:-Cushioning material, mattresses, packaging, foils for laminates, insulating material, and in construction of motor cars and aircraft.

Abstract: 1297780 Audible signalling-apparatus; automatic alarm systems TRW Inc 12 Dec 1969 [26 Dec 1968] 60695/69 Headings G4F and G4N A multiple-input buzzer adapted for use as an inadvertence signalling device in a motor vehicle comprises a core 11 upon which two equal windings 12, 13 are wound and connected in series such that one end 14, 15 of each winding connects commonly through a control switch 16a to chassis ground 18. The other end 19 of winding 13 connects to ignition terminal 20 which communicates to ground through ignition circuitry (not shown) of about 3 ohms resistance. Terminal 21 of winding 12 connects to relay contact 22 normally open with respect to contact 23 connected by line 24 to control terminal 16. Contact 22 connects through individual isolating resistors 25 to a number of input terminals 26 each connected typically as shown in the case of terminal 26b to a lamp circuit 27. When the ignition is on, the control switch 16a is closed as by the opening of the vehicle door on the driver's side, and an input terminal 26 is energized, then the two windings 12, 13 whether in bucking or aiding relationship obviate any buzzer action. If the ignition is off, however, winding 12 serves in its buzzing function. If the control switch 16a is then closed (the vehicle door is open), and there is impressed at any terminal 26 a voltage, current flows through winding 12 to ground 18 and the winding 12 magnetizes the core 11, closing contacts 22, 23, shorting winding 12 and thereby demagnetizing it and consequently releasing the contacts 22, 23 starting the next buzzer cycle by causing current to again flow in winding 12. The device thus serves as an inadvertence warning buzzer giving a buzzer signal after the vehicle ignition has been turned off and the driver has opened the door to leave the vehicle but has inadvertently left the lights (or some other electrical device) on. The buzzer will not operate when the ignition is on or the door is closed.
