Title: Stable solid compositions for use in preparing cleansing and disinfecting solutions
IPC: C11D3/395
Filed: 1946-03-05
Abstract: A stable, solid cleansing composition forming a clear solution in water, consists essentially of a mixture of lithium hypochlorite with a greater amount of one or more alkaline substances selected from the water-soluble alkali metal carbonates, silicates and normal monophosphates (i.e. containing one atom of phosphorus per molecule and having no replaceable hydrogen) or with mixtures of such carbonates with the corresponding acid carbonates and mixtures of such normal monophosphates with alkali metal monophosphates. Anhydrous alkaline material and lithium hypochlorite of water content not greater than 6 per cent, and preferably not greater than 2 per cent, are used.  Turbidity in hard water is prevented by the addition to the composition of not more than 5 per cent of alkali metal polyphosphates, such as sodium pyrophosphate, sodium tetraphosphate, sodium hexametaphosphate and sodium tripolyphosphate.  The composition may also contain a wetting agent such as sodium decylbenzene sulphonate, sodium isobutyl naphthalene sulphonate, sodium lauryl sulphate, and a sulphated or sulphonated stearyl compound, alone or with a dessicant such as sodium monoxide. Specifications 195,366, 216,450, [both in Class 1 (ii)], 581,944 and 581,945 are referred to.ALSO:A stable, solid composition forming a clear aqueous solution and useful in cleansing disinfecting and similar operations, consists essentially of a mixture of lithium hypochlorite with a greater amount of one or more alkaline substances selected from the water soluble alkali metal carbonates, silicates, and normal phosphates (i.e. containing one atom of phosphorus per molecule and no replaceable hydrogen atoms), or with mixtures of such carbonates with the corresponding acid carbonates and mixtures of such normal monophosphates with alkali metal acid monophosphates.

Title: Pulse position modulation communication system
IPC: H04B14/02
Filed: 1972-02-15
Abstract: 1347928 Pulse position modulation transmission system NIPPON ELECTRIC CO Ltd 15 Feb 1972 [25 Feb 1971] 7020/72 Heading G4H In a pulse position modulation system, the sum, on a modular M basis, of an input digital quantity and an immediately preceding sum digital quantity is transmitted as a position modulated signal having a one-to-one correspondence to M time slots. At the receiver the number of time slots, on a modular M basis, between two adjacent received pulses is produced; this being the same as the transmitter input. In the described system, each digital word comprises 3 bits and the number of time slots per word is 8. The digital input (9 3 , 9 2 , 9 1 ) is applied to coincidence detector 2 via buffer 1. A clock signal d is applied to 3-bit binary counter 3 and square wave outputs e 1 , e 2 , e 3  are produced at one half, one quarter and one eighth respectively of the clock frequency. These outputs are compared at 2, and, on coincidence an output f is produced. Inhibit circuit 5 prevents another pulse reaching output 30 before the end of a digital word (8 clock pulses d), and is controlled from clock 4 via flip-flop 31. Each output pulse is in the time slot corresponding to the sum, on a modular 8 basis between the input signal and the immediately preceding sum signal. At the receiver, the incoming signal is fed directly to a store 12, clock 13 and word synchronizer 15. It is also fed to counter 11 after a delay equal to one time slot. An incoming pulse clears store 12 to buffer 14 and after delay 10 transfers the count in counter 11 to store 12 and clears the counter. Clock 13 generates a clock signal at the same frequency as the clock 4 in the transmitter and this signal is fed to counter 11 which indicates, on a modular basis, the number of time slots between incoming pulses and hence regenerates the input signal at the transmitter. The word sync. circuit 15 and buffer 14 operate to synchronize the output words with the input. If two pulses are received during word period of eight time slots, the word phase at the receiver is shifted by one time slot at a time until only one pulse is received per word. The buffer stores the output signals during this period so that the output signals are of equal lengths.

Abstract: 944,802. Twisting; stretching. DER VON MOOS'CHEN EISENWERKE A.G. March 1, 1960 [March 1, 1959], No. 7301/60. Heading B3E. A method of twisting rods for reinforced concrete comprises twisting a length of rod, unwound from a coil mounted on a reel, cut therefrom and clamped between a twisting head and a vice, while simultaneously unwinding a further length of untwisted rod and feeding it to a position adjacent the twisting head and vice. Rod 29<SP>1</SP> unwound from a reel 28 passes through a tubular guide 30 and has its end clamped between a jaw 61, Fig. 7, on a feed carriage 60 and an eccentric 63 turned by a handle 64. The carriage 60 runs on horizontal rails 56 and is connected by cables 65, 66, passing over pulleys 68, 77, with a second carriage 60 running on parallel rails 56. Upon actuation of a lever 76 the pulley 68 is driven and a carriage 60, with the end of the rod 29<SP>1</SP> gripped thereon, moves from a position adjacent a stand 25 to a position adjacent a stand 1 to engage stops 82 to halt its movement, the other carriage 60 being moved to the stand 25. The end of the rod 29<SP>1</SP> is then released from the carriage 60 and gripped in a twisting head 11 in the stand 1, the jaws of the head 11 being closed by a ring 12 moved by a link 14 and piston 16 to which oil under pressure is supplied under control of a cock 24. The part of the rod 29<SP>1</SP> near the stand 25 is placed between jaws 37, 38, Fig. 5, of a vice 36 on a slide 35 movable, to or from the head 11, on and relative to a stand 31 adjustably fixed near the stand 25. A lever 51<SP>1</SP> controlling a cock 51 in an oil pressure line, is then actuated to supply pressure to a cylinder 47 to lower the jaw 38 and a knife 40 thereon so that the length of rod 29<SP>1</SP> between the twisting head 11 and vice 36 is cut-off from its supply and the end of the cut-off length is gripped by the vice. The cut end of the rod on the reel is gripped on that carriage 60 now adjacent the stand 25. A switch 6 is operated to engage a clutch 5 to rotate the head 11 and twist the rod 29<SP>1</SP> between it and the vice 36 which is simultaneously moved away from the head 11, to stretch the rod by a-piston in a cylinder 50. The lever 76 is actuated at the same time as the switch 6 so that the carriage 60 pulls the rod 29<SP>1</SP> from the reel 28 towards the twisting head 11 as the previously cut length of rod is twisted and stretched. After twisting and stretching the clutch 5 is disengaged and the twisted rod discharged on to rolls 87. After all the coil is cut up any residue of less than standard length has its end bent to form a hook and attached to an intermediate hook member held in the vice 36. Lengths of rod may be supported prior to twisting on a carrier 89 swingable about a vertical shaft 88.

Title: Improved pitch controlling means for rotor blades of helicopters
IPC: B64C27/54
Filed: 1945-03-24
Abstract: 605,561. Helicopters. NEALE, J. S., and PENNINE AIRCRAFT, Ltd. March 24, 1945, No. 7472. [Class 4] A blade pitch control system for helicopters is characterized by means responsive to aerodynamic forces on the blades to effect cyclical pitch changes thereof automatically, so that the pitch of the blades is varied by changes in their airspeed. In the form illustrated the rotor carries three blades 19 whose roots are rotatably mounted in sockets 17 for pitch changing, and is mounted on a spherical bearing 10 for adjustment in azimuth, effected by pushpull control members 12. The latter serve as conduits for hydraulic pressure liquid for effecting collective pitch control of the blades, the liquid operating spring-loaded pistons 27 which actuate pistons 33 moving in cylinders 34 communicating with upper and lower sets of cylinders 35, 36, each of which contains pairs of spring-loaded pistons 35a, 36a, connected to diametrically opposed crank arms 38 at the ends of the blade roots. The profile of the rotor blades is such that they tend to assume smaller angles of attack with increasing airspeed, whereby the blade moving at the greatest relative velocity will tend to reduce its angle of attack, so transmitting an impulse to the constant-volume hydraulic system, and increasing the pitch of the remaining blades against the action of the piston springs which are so disposed as to oppose pitch increase, whereby during rotation of the blades there is a continuous automatic cyclic change of pitch.
