Title: Improvements in and relating to cellular urea-formaldehyde resins
Inventor: PILGRIM THOMAS ALBERT
IPC: C08J9/30
Filed: 1962-11-01
Abstract: <PICT:1064326/C3/1> Cellular urea-formaldehyde resins are made by a method which comprises in the first stage agitating a mixture of urea-formaldehyde resin, foaming agent and water in the presence of air, the duration and intensity of agitation being sufficient to produce a fine foam in which there are at least 104 cells per cubic centimetre, the proportions of resin, foaming agent and water being selected to provide in the foam a maximum volume of resin which does not exceed that which obtains when the total volume of the solid resin per unit volume of the cellular resin is 2.2% and the average number of cells per cubic centimetre is 106; in a second stage adding a hardening agent in an amount sufficient to harden all of the foam, and continuing to agitate the foam up to a point before gelation, the intensity and duration of which being sufficient to maintain the size of the cells on gelation.  The foamed resin may be dispersed into fragments at the point of gelation to produce pellets.  Any conventional foaming agent may be used, but those preferred are sodium salts of higher alkyl sulphates.  Suitable hardening agents are suphuric, hydrochloric, phosphoric and formic acids.  In Fig. 1, a urea-formaldehyde resin and water are fed from supply tank 1 through conduit 2 to a first stage rotary mixer 3.  Water containing foaming agent is also fed to mixer 3 from supply tank 5, and the mixer 3 is pressurized with compressed air from compressed air supply 8.  The mixture is then beaten into a fine foam and is then fed on to a second stage rotary mixer 14 where it is further beaten whilst an acid hardening agent is added from supply tank 15.  From the mixer 14 the gelling foam enters a pelletizer 18 which is shown in Fig. 3. The gelling foam passes through holes 20 in the supply conduit 19 to a gap between a pair of rotating cones 21 and thence into a drying chamber 22 in the form of pellets which are further broken up by air jets from a conduit ring 23 disposed above the cones 21 and having a plurality of holes 23a in its base. The conduit ring 23 is supplied with compressed air from the supply 8.  The temperature of the drying chamber 22 is maintained at about 300 DEG  F. by circulating heated air through inlets 27 from a fan 25 through a heater 26. At frequent intervals the valve 30 is opened to allow the pellets to fall into chamber 31 and they are then swept by an air stream into a separator cyclone 34 where they settle to the bottom.  The pellets then pass through a rotary sieve 36 and are then swept by an air stream into a second separator cyclone 39 from where they pass into a storage hopper 40.

Abstract: 1,118,346. Traversing yarns. HEBERLEIN & CO. A.G. 8 Oct., 1965 [13 Oct., 1964], No. 42825/65. Heading D1J.  A yarn traverse mechanism of the kind in which the yarn guide is carried by a slide block traversed back and forth by drive means, is characterized by stroke displacement means operable by the back and forth movement of the slide block to displace the stroke of the slide block relatively to its drive means without altering the length of the stroke.  In Fig. 2 a grooved drum 12 houses a cam follower 10 eccentrically mounted on a shaft 6 in a sliding block 1, the block 1 moving along a guide 3 and carrying a yarn guide arm 29. The shaft 6 is coupled to a further cam follower 24 via a one-way rotary coupling 14. As the follower 24 is reciprocated along a cam track 26 it causes the one-way rotary coupling 14 to turn the shaft 6 in a step-by-step manner and this, in turn, causes the sliding block 1 to be displaced in a step-by-step manner relatively to the cam follower 10.

Filed: 1962-11-13
Abstract: 1,017,405. Automatic control of voltage and frequency. AMERICAN MACHINE & FOUNDRY CO. Nov. 13, 1962 [Dec. 15, 1961], No. 42881/62. Heading G3R. [Also in Division H2] A regulating system for a motor-generator inverter includes controlled rectifiers, one in the motor field circuit and one in the generator field circuit, which are controlled to maintain the voltage and frequency of the A. C. output substantially constant. As shown, a D. C. motor 2 energized from D. C. terminals 4, 5 drives a generator 6 providing an A. C. output at terminals 9, 10. The field winding 3 of motor 2 is connected to terminals 4, 5 over a controlled rectifier 11, and the field winding 8 of generator 6 is similarly connected over a controlled rectifier 12. Rectifier 11 is turned on at a point in an output half-cycle by a circuit 48 responsive to the output frequency and rectifier 12 is similarly turned on at a point in the output half cycle by a circuit 48 responsive to the output voltage. Both rectifiers 11, 12 are turned off at the end of the half-cycle by a circuit 19 which, at the appropriate time, causes a controlled rectifier 15 to fire, thereby allowing a capacitor 16 to discharge through the rectifiers 11, 12 to extinguish them. The charging circuit 41 for the capacitor 16 includes a saturable reactor 44, and derives its supply from a transformer 22 connected to the output terminals 9, 10. A Zener diode 28 acts as a source of reference potential for the circuits 19, 47 and 48. The arrangement is such that the time for which field winding 8 is energized, i.e. the time between the pulses developed by turn-on circuit 47 and turn-off circuit 19, varies inversely with the magnitude of the generator output voltage, which is thus maintained at a substantially constant value. Similarly, the speed of motor 2, and hence the output frequency, is maintained constant by controlling the time duration of energization of field winding 3 in response to pulses from circuits 48 and 19. Suitable arrangements for the circuits 47 and 48, which both include uni-junction transistors, are described with-reference to Figs. 4 and 5 (not shown). The commutating circuit for the controlled rectifiers 11 and 12 may include two capacitors (Fig. 3, not shown).

A vehicle hydropneumatic damping, spring- ing and height regulating suspension unit comprises a working chamber, reservoir and valve means for transfer of hydraulic fluid to and from the working chamber and is characterized in that there is provided a feed chamber with fluid at a higher pressure than that of the working chamber and associated pumping means operated by suspension unit movements. The embodiment shown in Fig. 1 comprises a casing 12 containing a working cylinder 1, a damping piston 2, with damping holes 20, 21 some of which are closed on rebound, a reservoir 16, a resilient chamber divided into gas-filled and liquid-filled spaces 6 and 6<SP>1</SP>, by diaphragm 10, a feed chamber divided into gas- and liquid-filled spaces 9, 9<SP>1</SP> by diaphragm 8, the gas spaces being pressurised through non- return valves 17 and 11, and a pump body 7 containing a piston 14. When the vehicle rises fluid passes from the reservoir 16 through tube 28 and non-return valve 27 to the chamber in the pump body below the piston and then as the vehicle falls pump piston 14 is pushed down by spring 13 forcing liquid past non-return valve 25 into the feed chamber 9<SP>1</SP> When the feed chamber pressure reaches a sufficient value the force of the spring 13 will not open the non- return valve 25, the spring being compressed without depressing the pump piston 14. Vehicle height is increased by fluid flowing from the feed chamber 9<SP>1</SP> when the damping piston 2 contacts spring 22 opening valve 24 through pin 23. When the vehicle is too high hole 21 in damping piston allows flow back into the reservoir from the working cylinder. In Figs. 2-6 (not shown) the pump piston is connected directly to the damping piston and alternative feed chamber pressure limiting means are shown. Figs. 7-11 (not shown) show alternative arrangements of the reservoir working cylinder and pump body and piston. The embodiment of Fig. 12 is similar to Fig. 1 with the addition of fluid braked damping means to give gradual operation of the height control means.
