IPC: H03K19/16
Filed: 1960-01-12
Abstract: 911,922. Parallel adders. SPERRY RAND CORPORATION. Jan.12, 1960, No. 1168/60. Class 106 (1).  The secondary windings of transformers whose primaries receive binary inputs corresponding to augend, addend, and carry, are arranged in tree formation, only one path being effective to energize the appropriate outlets. Carry, augend and addend binary digits are applied at C, A, B, Fig. 1, and their complements at C<SP>1</SP>, A<SP>1</SP>, B<SP>1</SP> in the form of pulse or no pulse. A pulse causes the associated transistor 34 to conduct and energizes the primary winding 24 of an associated transformer. A voltage is therefore induced in the secondaries 26 which are 1, 2 and 4 in number for levels C, A and B, respectively. The secondaries are arranged in a tree formation in series with a current limiter 68, such that for each combination of C, A and B digits only one path is energized. The lower end of each path is connected to an appropriate combination if sum and carry outputs and their complements S, S<SP>1</SP>, OC, OC<SP>1</SP>. Bi-quinary adder, Fig. 4. Digits 0-4 and 5 or 0 may be applied as augend and addend to terminals A0-A4, A5, A6 and B0-B4, B5, B6. The carry input is fed in real and complementary form to terminals C, C. The quinary part of the adder has three levels using stages 164, 166, 168 of the same type as used in Fig. 1, and has outputs S0-S4. The quinary adder also energizes either the internal quinary carry lead CQ or its complementary lead CQ<SP>1</SP>. The binary adder energizes S5, S6, OC, OC<SP>1</SP> according to whether its output is 5, 0, carry, no carry, respectively. Modifications. The transistors may operate in common base mode. The adding circuits may have more than three levels. Clock pulses may be applied in place of negative battery to the lower end of the transformer primaries. Clock pulses of opposite phase may be applied to the real and complementary input stages.

Title: Method of purifying solutions of antibacterially active substances derived from the growth of micro-organisms
Filed: 1949-01-17
Abstract: Aqueous solutions of antibacterially active substances derived from the growth of microorganisms are purified by adding a gel of aluminium hydroxide to the solution adjusted to a pH value between 3 and 8 (preferably 4.5-5.5), and removing the gel after it has adsorbed the impurities present.  Preferably the gel, before being added to the solution, is itself adjusted to the pH value at which the adsorption is to take place, and it may also be concentrated, e.g. by decantation or centrifuging.  A detailed example is given. Specification 631,349 is referred to.ALSO:Aluminium hydroxide gel for use as an adsorbing agent is prepared by precipitation of a soluble aluminium salt with a basic substance such as ammonium hydroxide at concentrations suitable for obtaining a precipitate of good adsorption capacity.  The pH of the gel may then be adjusted to that at which adsorption is to be effected, and it may be concentrated by removal of excess liquid, e.g. by decantation or centrifuging.  In an example, an aqueous solution of aluminium sulphate is added with agitation to a solution of ammonium sulphate in aqueous ammonia, the mixture is poured into a large amount of water, the pH is adjusted to 5.0 with sulphuric acid and the gel concentrated to about 3 per cent aluminium hydroxide content.

Filed: 1973-01-12
Abstract: 1416933 Vibrators DYNAPAC MASKIN AB 12 Jan 1973 [13 Jan 1972] 1709/73 Heading F2X A pneumatic vibrator comprises a casing 1 inside which a roller 2 is arranged to describe an eccentric and vibration-generating rolling motion by means of compressed air admitted via an intake 3 and a passage 4 extending longitudinally through the roller 2. From passage 4, the air passes to the space between threaded and interacting parts 5, 6 formed on oppositely facing walls of the roller 2 and casing 1 respectively. A sleeve-shaped valve device 8 is arranged around the end 7 of the roller 2 remote from the intake 3. The end of the valve device remote from the roller 2 has a tapered depression 11 serving as a race for a regulating rolling body, shown in Fig. 1, in the form of a ball 12. The vibrating motion of the vibrator causes the ball 12 to roll and, when a certain acceleration value is reached, the ball presses against the race 11 with such a force that the valve device 8 is moved axially against the force of a spring 9, located between the valve device 8 and a shoulder 10 on the casing 1, and abuts the end 7 of the roller 2. The result is that the air gap between the valve device 8 and the outlet from passage 4 is restricted and consequently the air supply to the vibrator is limited, with a reduction in vibration frequency as a result. An alternative form of regulating rolling body, shown in Fig. 3, is a ring 13 which is designed to roll against a tapered race 14 formed on a valve device 15 which, under the influence of the ring 13, can be moved against the force of a spring 16 causing a restriction of air supply to the vibrator. The valve device 15 is arranged to slide on the end 7 of the roller 2 and totally embraces the spring 16, one end of which rests against the valve device 15 and the other end against a stop 17 on the end of the roller 2.
