Patent GB-601308-A (GB)
Title: Mixed aldehyde condensation products and processes of producing same
IPC: C08G14/10
Filed: 1944-05-13
Abstract: In a process of condensing together resorcinol, formaldehyde and an incompletely polymerized melamine-formaldehyde condensation product an alkali is added.  The preferred molar ratio of resorcinol to formaldehyde (excluding formaldehyde combined with the melamine) varies between 1 : 1 and 1 : 3.  Sufficient alkali is added to produce a pH of 7.5 or higher.  Suitable alkalies are caustic soda, triethanolamine, potassium hydroxide, sodium carbonate, potassium carbonate, or triethylamine.  Part of the melamine may be replaced by dicyandiamide or urea.  The products are especially suitable for cold-setting adhesives and may be used to bond plywood or other laminated articles.  Speed of curing may be adjusted by varying one or more of the following factors: the ratio of formaldehyde to resorcinol, the ratio of formaldehyde to melamine, and the alkalinity.  In examples (1)-(8), a condensation product is used prepared from 1 mol. melamine and 3 mols. formaldehyde at pH 6.3, followed by dehydration at pH 8-8.5, cooling and grinding.  The powder is water soluble.  In example (1), this product is dissolved in formalin, and resorcinol and caustic soda are added and the mixture heated to 50 DEG  C.  The reaction is exothermic and the product gels and soon hardens to a clear or white mass.  Example (2) is similar, but the condensation is effected without alkali, and the effect of adding varying amounts of alkali to portions of the condensation product is described.  The products are particularly resistant to acids and boiling water.  In example (9) trimethylol melamine is employed and in example (10) hexamethylol melamine. Specification 502,720 is referred to.

Title: Improvements in or relating to loading means for maintaining dynamic loading on annular thrust members
Inventor: CLENCH EDWARD CLAUDE SHAKESPEA
IPC: B02C15/12
Filed: 1960-03-16
Abstract: 895,873. Ball-and-ring mills. AUTOMOTIVE PRODUCTS CO. Ltd. Feb. 23, 1961 [March 16, 1960], No. 9310/60. Class 59. [Also in Groups XXVI and XXIX] A ram-and-cylinder unit 19 for loading a thrust member 12 of a ball mill comprises a liquid chamber and a gas chamber separated by a movable separator 25 and arranged so that the total volume of the chambers is increased by extension of the unit and vice versa, a liquid pressure source 29 connected to the liquid chamber and operative to maintain a substantially constant value therein, and a pressure gas storage means 31 connected to the gas chamber through valve means 32 preventing flow of gas back to the storage means, the gas pressure being at least equal to the liquid pressure. The thrust member 12 is urged against the balls 11 of the mill by a plurality of pairs of units 19 connected to the thrust member by levers 14, 17. Each unit has a ram 18 in the form of a sleeve which is disposed in a cylinder 20 and receives the separator in the form of a piston 25, a ring 26 limiting the movement of the piston towards the closed end of the cylinder. The liquid pressure source 29 is connected to ports 27 in the cylinders to extend the units and the gas storage means 31 is connected by a reducing and non-return valve 32 to ports 28 so that gas pressure acts on one side of the piston and liquid pressure on the other. The liquid pressure is maintained at a constant value of, say, 1,000 lbs/sq. in. and the valve 32 is adjusted so that the pressure in the gas chamber is at a greater value, say 1,050 1bs/sq. in. The units thus act to load the thrust member 12 and in the event of the passage of a large fragment in the mill, the thrust member moves the rams into the cylinders and moves the pistons away from the rings 26 to compress the gas and absorb the extra load.

Title: Automatic brilliance control for cathode ray oscilloscopes
IPC: G01R13/26
Filed: 1946-03-29
Abstract: 615,989. Cathode-ray oscillographs. KODAK, Ltd., DIGHTON, D. T. R., and ROSS, H. M. March 29, 1946, No. 9760. [Class 37] The deflecting potential is differentiated by a resistance-capacity circuit, rectified and then applied to modulate the intensity of the cathode ray so that the brilliance of the beam varies with the speed to give a constant apparent brilliance for a wide range of speeds of deflection. The potential applied to the Y1-plate is amplified at VI, differentiated by condenser C1 and resistance R1, amplified at V2 and rectified at V3 to produce a modulating potential across resistance R5, R6. The potential from the Y2-plate is similarly treated to provide a modulation for downward movement, while the X-plate potential is amplified at V4, differentiated at C3, R6 and added to the other modulating potentials.

Filed: 1933-03-31
Abstract: 417,386. Impedance networks. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. March 31, 1933, No. 9790. Convention date, April 1, 1932. [Class 40 (iii).] In a filter of the Wheatstone-bridge type for use in telephony the input and output connections a, b, Fig. 1, form the diagonals of the bridge and one pair of arms comprises two inverse band-pass filters F1, F2, having the same pass band so that the bridge acts as a band-suppression filter, being approximately balanced for the pass range and greatly unbalanced for the suppression range of the component filters. A receiver A, Fig. 1, may be connected to the pair of filters F1, F2 in shunt as at Ap, Fig. 7 (Cancelled) (and Figs. 2, 3, not shown) or in series as at As ; the whole of the input energy from line l then passes to this receiver if the frequency lies within the pass range of filters F1, F2 ; otherwise it passes to the receiver R. Similarly, transmitters at A and R will feed the line l independently for their appropriate frequency ranges. Three such networks having different frequency-ranges may be connected in cascade, instruments being connected at the c and d terminals of each as well as to the b terminals of the whole network (Fig. 4, not shown) ; and the alteration of the impedance-level by the transformers T may be avoided by the use of two networks connected by their b terminals (Fig. 5, not shown) ; the two transformers may then coalesce into a single transformer S, Fig. 7 (Cancelled), (and Fig. 6, not shown). The terminals c, d may be used for carrier transmission while the terminals a' are used for telephony. Two networks of the kind shown in Fig. 1 may also be connected through c and d terminals as in Fig. 7, where the filters F2, F<1>2 comprise half-sections inverse to the half-sections F1, F<1>1. Frequencies lying within the passband of these filters can pass from the line l to the instrument R<1>a; but other frequencies pass to the instrument Rb. The instrument Rb may be a telephone and the instrument R<1>a a telegraph, the filters 2 being simplified to form a low-pass filter with cut-off at 80 c. /sec. (Fig. 8 not shown). The telephone Rb may be replaced by a further network in cascade ; this enables two instruments corresponding to Rla and one corresponding to Rb to be employed, each working on a different frequency-range (Fig. 9, not shown). This arrangement may be extended to allow for five instruments in all, and the transformer coils may coalesce into tapped chokes (Fig. 10, not shown). The Specification as open to inspection under Sect. 91 comprises also the filter illustrated in Fig. 7 (Cancelled) and also the two-way repeaters described in Specification 420,595 This subject-matter (except that described above with reference to Figs. 2-6, not shown) does not appear in the Specification as accepted.

Filed: 1955-04-05
Abstract: 768,882. Kneading boiled sugar. SOC. PER AZIONI G. RUFFINATTI. April 5, 1955 [Jan. 11, 1955], No. 9901/55. Class 86. A mass of boiled sugar on a table or shallow basin 2 is kneaded by the jaws 5, 6 of two opposed shovels. The jaws are first advanced towards each other in a substantially horizontal direction, so as to compress the mass therebetween, and then retracted; next the jaws are again advanced towards each other and simultaneously raised through an angle of about 30 degrees; the jaws are then lowered and, afterwards, retracted; finally the table is rotated through, say, a quarter of a revolution, and the successive movements of the jaws repeated. The jaws 5, 6 have, respectively, a cutting edge 9 and a blunt edge 10, to cause a rotation of the mass upon itself during kneading, and preferably the jaws, their arms 7, 8 and the plate 2 are hollow for the circulation of cooling water. The mechanism for effecting the intermittent rotation of the table and the various movements of the jaws is actuated by a single motor 11 through a two-speed gear mechanism, comprising parallel shafts 14, 17 having, respectively, loose and fixed gear wheels 15, 16 and 18,19 ,and an associated slidable coupling collar 20, a worm 32 on the shaft 17, and a spindle 34 which is driven by said worm 32 and carries three cams 37, 38, 39. The cam 37 controls the plate 2 which is adapted to be rotated at the end of a cycle of operations by the engagement of a worm, not shown, with a helicoidal gear wheel 31 on the table 2; similarly the cam 38, through a rocking lever 42, connecting rod 45, gear wheel 47, spindle 50 and shafts 54, 55, effects rotation of aear wheels 63<SP>1</SP> in engagement with racks 64 fast on the arms 7, 8 of the shovels to reciprocate the latter while the cam 39 and a similar cam 39<SP>i</SP> driven thereby are adapted to pivot the supporting sleeves 74<SP>1</SP> of the arms 7, 8, about the spindles of the wheels 63<SP>1</SP> by means of levers 68, 68<SP>1</SP> and linkages 71, 72 and 71<SP>1</SP>, 72<SP>1</SP>. The mechanism may be operated manually by a handwheel 25 when the coupling collar 20 of the two-speed gear mechanism is in its neutral position.

Filed: 1995-07-06
Abstract: A process is disclosed for direct isolation of captopril from a substrate of the formula <CHEM> wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.
