Patent GB-437085-A (GB)
Title: Improvements in or relating to the preparation of synthetic resin compositions
IPC: C08J3/21
Filed: 1935-03-14
Abstract: Compositions containing a purified phenolaldehyde resin are prepared by condensing a phenol with an aldehyde to the stage at which it is liquid when warm but plastic when cold, and pouring it whilst still in the fluid state into a liquid, e.g. benzene, xylene, water and ether, in which the condensation product is insoluble but the impurities soluble, a filler being suspended in the liquid.  The filler takes up the resin and the product, after being filtered off and dried, is useful as a moulding powder.  It may be further purified by dissolving it in acetone or alcohol and pouring the filtered solution into a suspension of the filler in benzene or the like.  When using aqueous formaldehyde for condensation with the phenol, only the lower resin layer is utilized.  According to the examples, phenol and m-cresol respectively are condensed with paraformaldehyde in the presence of ammonium hydrate and the warm product poured into benzene in which fuller's earth or wood flour is suspended.  The filtered product is washed with benzene or further purified in the manner described above.

Title: Improved method of filling cans or containers with ether and closing or sealing the same
IPC: B65B3/00
Filed: 1923-03-22
Abstract: 207,745. Mallinckrodt, E. March 22, 1923. Soldering.- In filling cans or containers with ether and sealing them, the containers are placed in a substantial vacuum, filled with ether, and hermetically closed by soldering or otherwise whila maintaining an atmosphere of gas containing no free oxygen during the filling and closing operations. As shown, the air-freed purified ether flows from the bottom of the distillation column 19 by a pipe 21 into an air-free storage tank 22, and is delivered into the cans or containers inside a filling-box 23 from which the air has ben displaced by pure nitrogen or other suitable gas. The cans may be fed into the box 23 from a pipe or reservoir 1 fitted with valves 2, 3. The air is first exhausted from the reservoir and the cans therein through a valved pipe 4 connected to the vacuum pumps 24, and then nitrogen &c. is admitted to the reservoir through a valved pipe 6 from a gasometer 14, which is also in communication with the box 13 and tank 22. The cans are supplied with caps or closures by a manually-operated suction tube 9 mounted in a universal joint and extending through the wall of the box 23, after which the caps &c. may be soldered on while the cans are in the box, the operators' hand being inserted in a rubber glove 11 having its sleeve portion hermetically connected around an opening to the wall of the box. The sealed can is discharged from the box through a water seal which prevents the entrance of air. The box is fitted with a glass observation window and may be illuminated by a lamp 13.

Abstract: 1,212,982. Automatic control of aircraft. SPERRY RAND Ltd. Feb.20, 1968 [Feb.22, 1967], No.8376/67. Heading G3R. In a system in which an aircraft is caused to follow a predetermined flight path by automatic control of throttle and elevator, engine thrust is also varied automatically in dependence on a timelagged forward acceleration signal. As applied to an aircraft which is being automatically controlled to maintain a constant altitude or to follow a glide path, airspeed is maintained constant by a signal from an airspeed meter 15, Fig.2, which controls an engine throttle servo 11 through a long term proportional plus integral controller. Short term variations of forward speed, e.g. due to gusts, are detected by a longitudinal accelerometer 12, signals from which are compensated for the effect of change of pitch by subtracting signals from a gyro vertical 16 so that true acceleration signals are delayed at 18 and applied in direct proportional to throttle servo 11 to increase thrust and correct a fall in altitude due to a following wind, for example. Signals from gyro 16 in response to pitch altitude changes are also effective to control throttle servo 11 through a circuit 19 having a smaller delay. Systems without speed or altitude control are referred to.

Title: Improvements in or relating to apparatus for compressing air or other gas
Inventor: MILLARD WILLIAM HARRY
IPC: F04C18/20
Filed: 1963-03-04
Abstract: 1,031,991. Rotary compressors and vacuum pumps. BYRAN DONKIN CO. Ltd. March 4, 1962, No. 8378/62. Heading F1F. In a rotary compressor or vacuum pump, a primary rotor 34 (Fig. 2, not shown) has two diametrally-opposed lobes 38, 40 and engages with a secondary rotor 36 having two diametrally-opposed lobe-receiving pockets 42, 44, the rotors being mounted on parallel shafts 54, 56 (Fig. 1, not shown) which are coupled to one another by gears 66, 68 lodged in an end cover 76 attached to an end plate 60 of a stationary casing 30 for the rotors. In operation, gas is drawn into the casing through an inlet 46 and compressed in a space or chamber 32 between the rotor 34 and the casing, the compressed gas being ejected through an outlet port 50 controlled by a valve 52 which remains closed until the pressure in said chamber is equal to that in an outlet duct 48. Alternatively, the primary rotor may comprise a single lobe (Fig. 11, not shown) or three lobes (Fig. 12, not shown), the secondary rotor having a corresponding number of lobereceiving pockets. An arcuate recess or depression 150 is formed in each of the end plates 60, 62 to allow compressed gas trapped in the lobe-receiving pocket in the rotor 36 which is mating with a lobe on the rotor 34 to escape into the other lobe receiving pocket so as to reduce vibration caused by low-pressure gas being conveyed by the lobe-receiving pockets from the region of the inlet 46 to the chamber 32. The compressor may be modified to include a port 208 (Fig. 13, not shown) to effect communication between a lobe-receiving pocket, which is approaching the chamber 32, and the outlet duct 48 so as to equalize the pressure in said pocket with that in said chamber and thereby reduce vibration. The port 208 may be provided in addition, or as an alternative, to the recesses 150, and may be included in any of the preferred embodiments. A pump 72 (Fig. 1) driven by the shaft 56 draws cooling oil from a sump (not shown) and delivers it to a port 74 communicating with a non-return valve 78 for conduits 80 82, 84 leading to transverse bores in the shafts 54, 56 through which the oil is ejected into cavities 88 in the rotors. The oil returns to the sump from said cavities through bores 90 and annular passages 92 surrounding the conduits 80, 84. When the rotors are stationary, oil is retained in the rotors by spring-biased valvemembers 94 abuting the ends of the passages 92. When the end cover 76 is removed, oil is retained in the rotors by spring-biased sleevemembers 106 closing holes 110 in the conduits 80, 84. The apparatus may comprise two stages constituted by two primary rotors 160, 162 (Fig. 10, not shown) which engage with a single secondary rotor 166, bores 172, 174 containing the primary rotors being in communication with one another through a valve 194 and an inter-cooler 178. The outlet duct duct 196 for the bore 174 is controlled by a further valve 194, both of said valves being similar to the valve 52.

Associating - apparatus; cutting and perforating apparatus; delivery apparatus; feeding webs; signature gatherers and the like; stapling and stitching devices.-A method of associating together a number of differently coloured or printed tickets or the like and forming them into packets or books in one operation consists in unwinding strips of tickets from a number of rolls and forwarding the strips in superposed relation to stapling or stitching and serving devices. The strips 1 pass from the rolls A round one or more guide-rollers 4 and the composite web B is fed between side guides 10, Fig. 2, under a knife 31 to a stapling or stitching device 34 of any suitable construction. A guard strip 5 prevents the strips slipping off the rollers 4 and a bar 7 and co-acting cam-operated brake block 8 is provided to hold the web B during the cutting and stapling operation. The strip B is fed intermittingly by pawls 11 pivoted to sleeves 12 slidable on rods 13 and the pawls and sleeves are operated by a sliding bracket 20 provided with jaws 19 engaging arms 11<1> of the pawls. During the forward movement of the bracket 20, the pawls are turned into feeding engagement with the web B and in the return movement are lifted clear of the web. The bracket 20 is operatively connected by side pins 20<1> with bell-cranks 22, 24, fixed to a cross-shaft 23. The bell-crank 22 is connected by a link 25 to a slotted lever 27 keyed to a shaft 28 provided with a hand-lever 29. An adjustable stop 30 limits the upward throw of the lever 29 and consequently the feed of the web B. The bell-crank 24 is provided with a handle 24<2> by which the feed of a longer length of web B may be effected by first disconnecting the shaft 23 from operative connexion to the handle 29. The downward movement of the handle 29 operates the knife 31 through a link 32 and operates the stapling-device by engaging the spring arm 34<1>, and may also operate a device for perforating the stapled packet. The packets are delivered by a device which flips them aside comprising an arm 38, Figs. 2 and 5, carried by a curved spring 35 carrying a, roller 37 engaging a rod 39 connected to the bell-crank 24 so as to be reciprocated vertically. The rod 39 normally holds the spring 35 in the position shown in full lines in Fig. 5, but is provided with a bent portion adapted to permit the spring to move inwardly as shown in broken lines to deliver the packet D. The handle 29 may be operated by the hand or foot of the operator or by steam, pneumatic, hydraulic, or electric power.

Title: Improved process for the preparation of insulin and insulin so produced
IPC: C07K14/625
Filed: 1954-03-24
Abstract: Insulin is selectively precipitated from an aqueous solution of insulin and non-insulin proteins having a pH on the acid side of the isoelectric point of insulin by increasing the pH of the solution to above 6,8 with agitation to redissolve precipitate formed at the isoelectric point, and then lowering the pH to between 5,9 and 5,3 to precipitate the insulin.  The aqueous solution may be obtained by dissolving insulin salt cake, or an isoelectric insulin precipitate prepared from the salt cake, in dilute aqueous organic or inorganic acid e.g. acetic acid, at a pH less than 4,0.  The pH of the solution may be raised by addition of an inorganic base e.g. ammonium or an alkali metal hydroxide, and a buffer e.g. ammonium acetate, which may be added or formed in situ, may be present on subsequent lowering of the pH of the solution.
