Title: A device for loading vehicles or containers
IPC: B65F3/04
Filed: 1966-02-24
Abstract: 1,134,921. Charging vehicles or containers. A. TALENTI. 24 Feb., 1966 [17 Nov., 1965], No. 8122/66. Heading B8E. A loading device for a vehicle or stationary container comprises a door 1, Fig. 3, mounted on a shaft B rotatably supported in a frame which is mounted on a shaft A rotatably supported on the vehicle, the door 1 having an opening 2, Fig. 1, corresponding to openings in receptacles to be emptied. The door 1 has a part 3 on which the receptacles rest and the opening 2 is normally closed by a flap 4 pivotally mounted on the shaft B at 5. A hood 6 having flanks 7 is rotatably mounted on the shaft A, its movement being limited by projections 9 and 10 thereon, and the flap 4 is connected to the flanks 7 by telescopic arms 13, the shortest length of which is that shown in Fig. 3. The shaft A carries levers 19, Fig. 2, loaded by springs 17 surrounding rods 18, and the shaft B carries levers 25 loaded by Belleville washers 21 carried on rods (22), Fig. 6 (not shown). In operation, a receptacle is carried upwardly by a device (not shown) to abut the door 1 and rotate it and its frame about the shaft A. The arms 13 cause the flap 4 to rotate about the shaft B, Fig. 4 (not shown). Rotation of the door 1 and its frame is continued until the latter engages abutments 11 on the hood 6 which is then rotated to its terminal position, Fig. 5 (not shown). The rotation of the shaft A loads the springs 17 so that they will return the door 1 and its frame to their initial position shown in Fig. 3. For charging bulky objects such as boxes or cases the door 1, the flap 4 and the shaft B are rotated by pushing on handles 26 provided on the door 1. The levers 25 are rotated with the shaft B and compress the washer 21 until a past-dead-centre position is reached when the washers move the door 1 and the flap 4 to their fully open position, Fig. 7 (not shown). The door 1 and the flap 4 are returned to their initial position by pulling on the handles 26. Alternatively, the door is operated by fluid power means. Abutments 27 on the hood 6 co-operate with the door 1 so that the latter can only be rotated with the shaft B when in the position shown in Fig. 3. The arms 13 may be dispensed with, the flap being operated by gravity.

Title: Improvements in plasticizing of vulcanized rubber scrap
IPC: C08J11/18
Filed: 1943-05-27
Abstract: Vulcanized rubber scrap is plasticized by working mechanically under oxidizing conditions with an acid and a plasticizing sulphide having the formula RSxR1, where R and R1 are the same or different hydrocarbon radicals which may be substituted with other groups other than those conferring accelerating properties, and where x is an integer.  The acid may be a higher fatty saturated on unsaturated acid such as stearic or oleic acid, or rosin acid may be used provided an antioxidant be added.  Small amounts only are required, depending on the amount of zinc oxide and similar materials present in the scrap.  The sulphides are non-accelerators of vulcanization and can be made by the action of sulphur chloride on phenols, naphthenes, or unsaturated compounds such as dipentenes.  Suitable sulphides are p-tolyl, hydroxyl-phenyl, tolyl, or naphthyl, or bornyl mono-, di-, or tetrasulphides, naphthene sulphides and dipentene sulphide.  The oxidation can be effected by atmospheric air or by the addition of small amounts of an oxidizing-agent such as benzoyl peroxide, hydrogen peroxide, or ammonium persulphate.  The process should be carried out below about 180 DEG  F.  Small amounts of accelerators such as diphenyl-guanidine, di-o-tolylguanidine, or cyclohexylamine may also be added to assist plasticization. The products can be revulcanized, or can be used to replace new rubber or reclaimed rubber obtained by other processes.

Abstract: 966,064. Aerodynamic gas analysers. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 6,1962 [March 7, 1961], No. 8562/62. Heading G1B. An aerodynamic gas analyser for determining variations in the composition of a gas mixture comprises two tubes connected in parallel and fed with a sample of the gas to be analysed, a first permeable member and a second permeable member disposed in the first tube, a third permeable member whereof the permeability varies in a different manner from that of the first permeable member, and a fourth permeable member disposed in the second tube, the second member and the fourth member being identical, and a differential pressure detector connected between the points intermediate in each tube. As shown, gas to be tested passes in through inlet 13 and lines 1 and 3 and identical sonic nozzles 16 and 17 before passing to sonic nozzle 14 having variable permeability and reference capillary tube 15 having constant permeability and then to outlet 6. When the concentration of one of the constituents in the fluid changes, the permeability of nozzle 14 varies and the resultant change in pressure is recorded on differential pressure detector 11 situated between pressure take off points 9 and 10. Thus variations in the proportions of the constituents in the gaseous mixture may be calibrated. The sonic nozzle may be replaced by a porous wall or a Venturi tube and the apparatus may be used continuously. The analyser may be placed in a thermostatically controlled enclosure and is a small device requiring only a very low rate of gas delivery. The analyser may be connected with a fluid circuit by means of pressure pick-ups or connections 20.

Filed: 1949-04-01
Abstract: 692,416. Multi-gap cold-cathode tubes. STANDARD TELEPHONES & CABLES, Ltd. March 31, I950 [April 1, 1949], No. 8903/49. Class 39(i) [Also in Group XL(c)] A cold-cathode gas-filled discharge tube comprises a number of main discharge gaps and a number of equal-length discharge gaps positioned between adjacent pairs of main gaps so that if one main gap only is initially discharging and independent potential differences are applied across the in termediate gaps, then the intermediate gaps fire in succession starting with the one nearest to the discharging main gap until the next adjacent main gap fires. The intermediate gaps have a smaller cross sectional area of discharge than the main gaps so that less current flows in an intermediate gap discharge. The Figure shows a discharge tube of the type described in Specification 692,415 having a common anode A3, cathodes K3, K4 and transfer electrodes TE3, 4, 5, the intermediate electrodes being of restricted surface area. The bias in the lead to cathode K3 is of such a value that normally the gap A3-K3 is discharging the spread of ionisation being such that a negative pulse of suitable amplitude applied at an input 16 causes gap A3-TE3 to fire and simultaneous or immediately successive pulses applied at inputs 17, 18 cause gaps A3-TE4 and A3-TE5 to fire until finally gap A3-K4 fires. Each gap may extinguish at the termination of its firing pulse or a gap once fired may continue discharging. The tube may be extinguished by a negative pulse applied to its anode. The gap A3-K3 may be extinguished when gap A3-K4 fires by the inclusion of a load resistor in the anode lead and by capacitors shunting the cathode resistors R6, R10. The gaps may be caused to fire in reverse order by rendering gap A3-K4 initially discharging and the tube may comprise more than two main gaps with intermediate gaps situated between each adjacent pair of main gaps. The gaps may be fired other than in succession by applying potential differences across two gaps which are spaced apart to cause them to fire and then causing a third intermediate gap to fire by application of a suitable voltage to it after a short delay period.

The bitumen is preferably a vacuum residue derived from a Venezuelan or Middle East crude oil and the copolymer is preferably a terpolymer of ethylene, propylene and dicyclopentadiene having a Mooney viscosity of 70. Suitable aromatic flux oils are "aromatic extracts" obtained by treating vacuum distillates and deasphalted vacuum residues with selected solvents. Suitably 10-50 parts by weight concentrate, preferably 25 parts, are dissolved in 100 parts by weight bitumen. The aromatic flux oil may be incorporated into the copolymer by milling at 90-150 C. and the mixture then added to molten bitumen in the blowing apparatus. The blowing of the concentrate is preferably carried out in two stages; the first stage at 180-230 C. and the second stage at 230-250 C. The blowing time is usually in the range 8-20 hours. The obtained concentrate is suitably incorporated into the unblown bitumen by agitation at a temperature of 170-200 C. In the examples the initial feedstock comprise 10% wt. terpolymer of ethylene, propylene and dicyclopentadiene, 30% wt. aromatic flux oil, 60% bitumen which may contain varying amounts of sulphur. The bitumen had a penetration of 185 mm./10 and a softening point of 41 C. 20 parts by weight of the blown material were then subsequently dissolved in 80 parts by weight bitumen.
