Title: Improvements in or relating to bag filling
Inventor: HAITH GEORGE GEOFFREY
IPC: B65B43/60
Filed: 1966-09-28
Abstract: 1,200,447. Bag-filling apparatus. HAITH ENGS. Ltd. 22 Dec., 1967 [28 Sept., 1966], No. 43332/66. Heading B8C. In filling bags with articles, e.g. carrots, they are first fed by conveyer 2 to a weighing device 10. When a predetermined weight, set on balance 13 is reached in the skip 16, a limit switch disconnects the drive to the conveyer 2. The skip 16 is then turned about axis 18 to discharge its contents into bag B supported at the end of one arm of a rotatable spider 22. The latter has several arms each carrying bag supporting means 30, 36 at their ends and is rotatable on a pillar 19 by means of an internal drive shaft. The pillar 19 is pivoted at its lower end so that when the bag B is filled it tips the pillar 19 about its pivot to engage the drive shaft for the spider 22 with the drive shaft 9 driven from the motor 5. This causes rotation of the spider to remove the filled bag from beneath the skip 16 and replace it by an empty bag on the succeeding spider arm. As the filled bag moves away from the filling position a return spring returns the pillar 19 to its vertical position to disconnect the drive to the spider. The momentum of the spider continues its rotation until a succeeding arm reaches the filling position where a spring urged locking detent locks the arm in position.

Abstract: 1499283 Flame retardant flexible polyurethane foams BRIDGESTONE TIRE KK 20 Oct 1976 [24 Oct 1975] 43572/76 Heading C3R A process for producing flame and smoke retardant, non-shrinkable, flexible polyurethane foams comprises reacting (A) at least one polyol Mol. Wt. 1000 to 10,000, having at least two active hydrogen atoms, (B) at least one polyhydroxyl compound Mol. Wt. 60 to 700, in an equivalent weight ratio of (B) to (A) in the range 0À5 to 2À0 with (C) a polyisocyanate, e.g. tolylene diisocyanate and (D) 0À5 to 10À0 parts by weight based on 100 parts of polyol (A) of one or more ammonium compounds which generate ammonia below 100 C. Polyol (A) may be a polyether polyol, e.g. poly(oxypropylene) and poly(oxyethylene-oxypropylene) triols or a polyester or a polyether-ester polyol. Suitable polyhydroxy compounds (B) are aliphatic diols, e.g. ethylene and diethylene glycols, glycerine, trimethylolpropane, pentaerythritol and low molecular weight polyesters and polyethers; aliphatic aminoalcohols, e.g. di- and triethanolamines, 2-amino-2-methyl 1,3-propane diol, tris(hydroxymethyl)aminomethane and N,N,N<SP>1</SP>,N<SP>1</SP>-tetrakis(2-hydroxypropyl)ethylene diamine, and heterocyclic polyols, e.g. trimethylolmelamine, hexamethylolmelamine and tris-(2-hydroxyethyl)- isocyanurate. Suitable ammonium compounds are ammonium carbonate, hydrogencarbonate, carbamate, hydrogencarbonate-carbamate, citrate and sodium ammonium hydrogen-phosphate. These compounds, some of which generate water and/or carbon dioxide in addition to ammonia when decomposed below 100 C., are used primarily to prevent the foam shrinking after the foam forming reaction has occurred although they also improve the flame and smoke resistance of the foam and act as reaction catalysts and blowing agents. In a typical example a polyoxypropylene triol Mol. Wt. 3000, trimethylolpropane (equivalent weight ratio of 1) and water are reacted with tolylene diisocyanate (NCO index: 100) and ammonium hydrogen carbonate in the presence of a stanncus octoate catalyst and a silicone surfactant using a one-shot technique to give a flexible, flame resistant foam having a density of 0À025 g./cm.<SP>3</SP> and a tensile strength of 0À85 Kg./cm.

Abstract: 1409442 Vinyl chloride-heterocyclic crosslinking compound copolymers AQUITAINE TOTAL ORGANICO 22 Sept 1972 [24 Sept 1971 19 Sept 1972] 43987/72 Heading C3P Vinyl chloride is copolymerized with compounds of the formula where R 1 , R 2 , R 3 , R<SP>1</SP> 1 , R<SP>1</SP> 2  and R<SP>1</SP> 3  are hydrogen or monovalent aliphatic or aromatic radicals, n and n<SP>1</SP> are 0 to 6, and R<SP>1</SP> completes an aliphatic ring structure. The copolymers may be obtained by the usual aqueous suspension techniques using free-radical catalysts. Other monomers, e.g. vinylidene chloride, acrylonitrile, methyl methacrylate, vinyl acetate and lauryl vinyl ether may replace part of the vinyl chloride and the copolymerization may be carried out in the presence of an elastomer, e.g. butyl rubber, ethylene - propylene - diolefin terpolymer and butadiene or isoprene polymers to form graft copolymers. The copolymers may be treated with peroxy compounds and further cross-linking monomers to increase the degree of crosslinking of the copolymer initially formed. In the examples, vinyl chloride is copolymerized with the diallyl- or the mixed vinyl allyl ester of imidomaleopimaric acid in an aqueous suspension containing polyvinyl alcohol and lauroyl peroxide, with addition of a defoaming agent and water towards the end of the copolymerization. The partially cross-linked copolymers are, in one case, further cross-linked by mixing with tribasic lead sulphate, polyethylene wax, triallyl cyanurate and 2,5-dimethyl-2,5- bis-(t-butyl-peroxy)hexane followed by. heating under pressure.

Title: Improved data transfer apparatus
IPC: G06F13/12
Filed: 1966-10-04
Abstract: 1,115,946. Data processing systems. SPERRY RAND CORPORATION. 4 Oct., 1966 [4 Oct., 1965], No. 44310/66. Heading G4A. In a data processing system, a control word address supplied by a peripheral unit accesses a control word from a memory in a central processor to control data transfer between the processor memory and peripheral unit, a bit in the control word selecting one half of an addressed memory word for communication with the peripheral unit. A plurality of input/output peripheral units communicate over respective channels with the central processor. Any peripheral unit requiring service energizes a respective request line. These lines are scanned repeatedly to cause the highest priority unit with the highest priority function (viz. input or output) requiring service to be selected, and an indication of it to be stored. Considering servicing of an input request, a parallel input word from the selected unit is accepted by the central processor, a half of the word addressing the processor memory to read out a control word respective to the channel. The second half of the input word is data which is stored in half of that memory word position specified by a " current address " field of the control word. A " word count field of the control word is decremented by one. The half of the memory word into which the data is placed is specified by a " half-word count " bit in the control word, this bit being complemented. If this bit, before complementing, is 1, and a certain two-bit field of the control word is 00 or 10 the " current address " field is incremented or decremented by one respectively. The control word, thus updated, is stored back in the memory. An acknowledge signal is sent to the peripheral unit being serviced, so that it can remove its input word from the channel and make another service request if required. When the " word count " field of the control word is updated to 0, an " active flip-flop respective to the channel is reset, preventing any further service requests from the channel from being honoured. If the " word count " is zero when the control word is read from memory, this indicates an error and storing in the memory of any data from the channel is prevented. Output requests are serviced similarly except that the " data " half of the " input " word is empty. The " half-word count " bit of the control word gates one of the halves of the memory word addressed by the " current address " field of the control word, to the channel. The same adder is used for updating the " word count " and " current address " fields. The invention is described as a modification of the " externally specified index " mode in Specification 943,833 which is referred to for details not modified.
