Patent GB-585232-A (GB)
Title: Improvement in recovery of polymerized olefines
IPC: C08F10/00
Filed: 1944-09-20
Abstract: <PICT:0585232/IV/1> Polyolefines, particularly polyethylene, prepared by gas-phase polymerization under high pressure and temperature, are collected by discharging the reaction mixture directly into a vessel closed to the atmosphere when charged, permitting separation of the gas from the polymer and its expansion to a lower pressure, maintaining a temperature sufficient to keep the polymer plastic and continuously extruding the polymer under the pressure of the unreacted gas.  The temperature is maintained by the heat in the unreacted gas and also if necessary by a heated jacket surrounding the vessel.  Where the polymerization is carried out at temperatures over 100 DEG  C., e.g. 200-300 DEG  C., and at pressures over 500 atmospheres, the unreacted gas may be allowed to expand in the vessel to 7-70 atmospheres, preferably 34, and the temperature maintained at 125-300 DEG  C.  The recovery of solid polyethylene is described using the apparatus illustrated, in which pipe 4 connects the reaction vessel through release valve 5 with the collection vessel. A large perforated pipe 6, surrounded by shield 7 is attached to the end of pipe 4.  Valve 8 controls the pressure in the vessel.  An expanded end portion perforated with holes 12 at the bottom of the vessel forms an extrusion nozzle from which the polyethylene is obtained in spaghetti-like filaments, unreacted ethylene being discharged through valve 8.

Title: Improvements in or relating to compositions containing griseofulvin
Inventor: RHODES ALAN
Filed: 1955-06-22
Abstract: A fungicidal or medicinal composition comprises the antibiotic griseofulvin dissolved in one or more of the following solvents: water-miscible N-alkyl amides of aliphatic acids, e.g. N,N-dimethyl formamide and N,N-dimethylacetamide, cyclohexanone, furfural and methyl-cyclohexanone.  The compositions contain at least 2.5 per cent w./v. of griseofulvin and preferably more than 5 per cent, and may be applied in the form of a spray, an aerosol, or used to impregnate timber or fruit wrapping paper.  When used medicinally against dermatomycotic infections they may be used as a spray or by atomization of a solution of griseofulvin. Preferably, the compositions contain also up to 10 per cent w./v. of a surface-active agent such as those sold under the Registered Trade Marks "Empilan Aq. 100," "Lissapol NX," "Lubrol" or "Sorbesters," and may contain sticking agents such as synthetic coumarone-indene resins.  Before use the concentrated solutions may be diluted with water when a suspension of griseofulvin is thus formed.  The compositions are active against many fungal diseases in plants, e.g. Chrysanthemum mildew (Oidium chrysanthenic) and Tulip fire (Botrytis tulipae).

Title: Improvements in or relating to electronic accumulators
IPC: G06F7/50
Filed: 1949-07-08
Abstract: 665,707. Digital electric calculating-apparatus. REMINGTON RAND, Inc. July 8, 1949 [July 8, 1948], No. 18183/49. Class 106 (i). In an electronic accumulator for digit values from 0 to 9 comprising a radix-of-two counter and radix-of-five counter including one and five double-triode trigger stages respectively, input circuits for the two counters receive pulses representing " 1 " and " 2 " respectively from a pulse generator, and a carry circuit is provided for transferring a pulse representing " 2 " from the radix-of-two to the radix-of-five counter. The accumulator described is for use with the pulse generator described in Specification 665,714, which, when started by a manually-operated switch, supplies the pulse trains shown in Fig. 5, b, f, e, hand d, over lines 31 to 35 respectively, Figs. 1 and 3, to a keyboard 25. The pulse over line 31 represents "1," and if an odd-digit key is depressed it closes contacts to connect line 31 to line 36 and the right-hand side of a normally cut-off double triode 27. The leading edge of the pulse, Fig. 5, b, causes conduction and produces a negative pulse, Fig. 5, m, in the anode circuit which is fed over line 38 to the double-triode trigger stage A-1 forming the radix-of-two counter. If any of the 2-9 keys is depressed, contacts are closed to connect the appropriate line 32-35 (corresponding to the digit, if even, and to the digit minus one, if odd) to line 37 and the left-hand side of double triode 27. Negative pulses of the form shown in Fig. 5, i to l, representing " 8," " 6," " 4 " or " 2," are then fed over line 44 to the right-hand grid circuits of doubletriode trigger stages A-O, 2, 4, 6, 8 forming the radix-of-five counter. For example, a single pulse representing " 2," Fig. 5, l, will switch over stage A-O (normally conducting on the right as indicated by the shade lines) which will then send a negative pulse over line 64 to switch over stage A-2 (normally conducting on the left). The left-hand anode of A-2 will then be at high potential and therefore the " 2 " or " 3 " indicating neonlamp 30 will light up according to whether the left or right-hand anode of A-1 is at low potential, i.e. according to whether stage A-1 registers " 0 " or " 1 ". If " 1 is already registered in A-1 and an odd key is depressed, the return to the normal condition will cause a positive pulse to be sent over line 41 to a normally cut-off triode 42 which will then conduct and send a negative pulse over lines 43, 44 to the radix-of-five counter ahead of the pulses from the keyboard. When the stage A-8 is returned to normal a pulse is sent over line 70 to switch over stage A-0 and a transfer pulse is sent over line 71. The accumulator may be zeroized by opening switch 50 which inserts a resistance 52 in series with the cathodes that are normally non-conducting.

Body motion and weight of rider, propelling by; treadle mechanism.-In a cycle propelled intermittently by action on treadles and as the result of the rider's weight being alternately applied to and removed from the saddle, the saddle is carried on an inclined slideway which is mounted on a carriage movable forwardly and backwardly. The carriage 7 is slidable on the longitudinal frame members 4, guiding and supporting rollers being provided. To the carriage 4 is attached a rod 35 trailing along the ground and either spiked or provided with a ratchet wheel 36 by which propulsion is effected. The carriage is moved forward by cords 5 passing over pulleys and connected to treadle levers 39. When moved to its extreme forward position, the carriage is locked automatically by scissors-like mechanism 13 which is released by the saddle 12 when at the bottom of its inclined slideway 10. The saddle carriage carries frame members 28 connected by elastic tension members 30 to the cycle frame. The cycle of operations is as follows :-When the carriage 7 is locked in its forward position and the rider's weight is applied to the saddle 12, the. saddle runs down its inclined slideway forwardly, extending the tension member 30 until it operates the scissors mechanism 13 and releases the carriage 7, which cannot move rearwardly owing to the rod 35 engaging the ground. The contraction of the tension members 30 moves the cycle forwardly until the carriage 7 is in its rearmost position on the frame. The rider then depresses the treadles 39 and moves the carriage 7 forwardly, the saddle being simultaneously raised.

Title: Improvements in and relating to bascule bridges or lever draw-bridges

Abstract: 699,710. Bascule bridges. WERKSPOOR. N. V. Aug. 9, 1951 [Aug. 9, 1950], No. 18774/51. Class 20(i) A bascule bridge or a lever draw-bridge has an angularly movable span 1 and actuating mechanism comprising a runway 13 attached to a bridge part, and a roller 12 co-operating with the runway 13 and adapted to be angularly reciprocated about a fixed axis 11 with constant speed. the span being unbalanced when approaching its closed position and kept unbalanced when closed, by the roller 12, the bridge part being adapted to be swung about an axis 17, Fig. 1, or 12, Fig. 3, with respect to the span during the unbalancing operation. To open the bridge, an electric motor 5 acts through gearing 6, 7 8, 9 to rotate an arm 10 carrying the roller 12 about the axis 11, this action serving to depress the bridge part about the axis 17 until an auxiliary weight 16 on the part engages an abutment 18 on a counterweight 19 of the span 1. Simultaneously, pegs 20 on the bridge part enter the weight 19, and the span swings about an axis coincident with the axis 17. Conversely, on closing the bridge, bevelled faces 26 on the runway act on the roller 12 to allow the weight 16 to be raised above the abutment 18, and a pivot 25 on the roller 12 acts through a linkage 24, 23, 22, 21 to disengage the pegs 20 from the container 19. In a modification. Fig. 3, the auxiliary weight 16 is dispensed with, and the bridge part is permanently connected at 27 to the weight 19, a spring 29 being connected to the axis 17 which can move vertically in its bearings 28. When the span 1 approaches closed position the bridge part is raised as before due to co-operation of the roller 12 and surface 26, the spring 29 tending to pull the bridge part downwardly about an axis formed by the engagement of the roller 12 and surface 26. and hence an upwardly directed movement about this axis is auplied to the weight 19 which therefore unbalances the span 1.
