Title: An improved distributor for use in telegraphy or the like
IPC: H04L5/24
Filed: 1930-02-12
Abstract: 348,543. Multiplex telegraphy. STANDARD TELEPHONES & CABLES, Ltd. and SANDEMAN, E. K., Columbia House, Aldwych, London. Feb. 12, 1930, No. 4737. Addition to 344,444. [Classes 40 (iii) and 40 (v).] Tn the parent Specification the paralysing waves alpha1 alpha2 of the lowest frequency were applied to the smallest group of valves, and those of the highest frequency #1, #2 to the group having the largest number of valves. To obviate errors due to the practical difficulty of generating square waves of the form shown, the paralysing waves of the lowest and highest frequencies, alpha1, alpha2, #1, #2 are supplied to the groups of valves having the largest and smallest numbers of valves respectively. In consequence, the paths from the valves D1 .. D16 to the apex valve L are not opened in numerical sequence, but the relay tongues T1 .. T16 are connected to the valves, so that the impulses from the relays R1 .. R16, when operated, will be transmitted in numerical sequence. In a modification, Fig. 2, the square paralysing waves alpha1, alpha2, #1, #2 of the lowest frequencies are replaced by sine waves alphaa .. alphad, #a .. #d, the a, b curves being opposite in phase to the c, d curves and being displaced in phase, relative to each other by a quarter of a period. In a further modification, Fig. 3 (not shown), the square waves alpha1, alpha1, #1, #2 are replaced by sine waves as described in connection with Fig. 2, but the paralysing waves of the highest frequency are, as in the parent Specification, applied to the row of valves having the greatest number of valves. Each single valve of the rows to which the displaced sine waves are supplied, is replaced by a number of valves corresponding to the number of waves utilized to simulate a single square wave.

Title: Casting synthetic resins
Inventor: MILLIGAN JOHN
IPC: B29C70/70
Filed: 1959-02-11
Abstract: A liquid cold-setting, solventless synthetic resin is fed into a mould and a mizture of heavy granular filler, catalyst and an inert liquid compatible with the resin is then added through the exposed surface of the resin, the inert liquid being present in an amount sufficient only to wet the surface of the filler so that the mixture forms a damp crumbly mass.  The preferred resin is a styrenated alkyd resin and the preferred filler is sand which may be used in an amount sufficient to fill the resin, i.e. to reach or nearly reach the resin surface on settling.  The liquid may conveniently be a plasticiser for the resin.  It is claimed that the above procedure enables casting to be effected without the need for vacuum filling techniques and the potting of transformers is referred to in particular.

Filed: 1921-02-12
Abstract: 173,443. Brander, A. Feb. 12, 1921. Working-fluid supply; circular-flow type; reversing; cooling parts; motor power plant.- Combustion products from explosion chambers n pass to the nozzles t for forward or reverse driving of the rotor d according to the position of the reversing valve t in the combustion chamber. The vanes a of the rotor d are formed with slots b cut to threequarters of the depth of vanes a, the slots in one row of vanes being staggered relatively to those in the next row. as shown in the exhaust passage c Fig. 2, to allow the gases to expand and to pass from vane to vane. Fig. 4, shows the valve-gear for the supply of the working fluid. Cam projections 1, 2 operate the lever f<1> and a quadrant x which controls the fuel pump p<11>, the valve t through the links w, w<1>, and a compressed-air valve o<2> through the links v, v<1>. The valve o<2> is arranged to open slightly before the nozzle t' is closed by valve t, and to close before valve t opens. For reversing, the links w, w<1> are moved to the position y and fixed by a spring catch w<2>. The cam projections 1, 2 are formed on one cam sheave i, Fig. 1, and the projections 3, 4, for the combustion chamber on the opposite side of the casing, are formed on a second sheave. These sheaves slide axially on the shaft k under the control of a governor h. There are two explosions in each combustion chamber per revolution of the rotor. The rotor d is cooled by water caused to enter through a conduit e and to pass out through a conduit f by an injector m which is provided with a hinged guide m<1>, Fig. 3, so as to operate in both directions. Cooling water is supplied to the spaces g in the casing and by the pipes r, Fig. 2, to the reversing-valve t which is made hollow. The water finally passes out by the pipes u. In the plant shown in Fig. 10, the exhaust from an internal-combustion turbine A as above described passes to a water-tube boiler E, the steam from which is led to a turbine C driving a compressor B which delivers air under pressure to a receiver D which in turn supplies the compressed air for the internal-combustion turbine A. The exhaust steam from the turbine C passes to a condenser F, the resulting water being used as cooling water in the turbine A after which it passes to the boiler E.

Title: Differential amplifier employing field effect transistors
IPC: H03F3/45
Filed: 1976-02-10
Abstract: 1486401 Transistor amplifiers INTERNATIONAL BUSINESS MACHINES CORP 10 Feb 1976 [21 March 1975] 05072/76 Heading H3T A differential amplifier comprises two parallel branches connected across supply terminals 12, 19, each branch including a depletion mode FET, Q1 or Q2, in series with an enhancement mode FET, Q3 or Q4 respectively, the gates of Q1 and Q4 being connected together to an input terminal 22, the gates of Q2 and Q3 being connected together to another input terminal 24, and output terminals 15, 35 being connected respectively between Q1, Q3 and between Q2, Q4. In the embodiment shown, with 12 positive, the FET's are all N channel, the drain of Q1 being connected to 12, the source of Q1 being connected to the drain of Q3 and the source of Q3 being connected to 19, the connections in the other branch being similar. If a positive going signal is applied to input 24, the conductances of Q2 and Q3 increase, so that 35 goes positive and 15 goes negative, a similar result being produced if a negative going signal is applied to input 22 so as to decrease the conductances of Q1 and Q4. Common mode signals applied to 22, 24 produce like changes in Q1, Q2 and in Q3, Q4, so that the differential output is small. By having both depletion and enhancement FET's the circuit switches faster than a corresponding circuit having only enhancement FET's, since all four FET's are affected by either positive or negative going signals. It is stated that such circuits may be directly connected together in cascade without the interposition of level shifting networks. Alternatively P channel FET's may be used, the supply polarity being reversed.

Filed: 1945-03-01
Abstract: 588,592. Powder distributers. RIPPER, W. E. March 1, 1945, No. 5149. [Class 6 (i)] [Also in Group XXIX] For spraying orchards or crops with liquid or with powder wetted by liquid carried to the trees by a high speed blast of air which provides turbulence and also disturbs the foliage, a machine on wheels comprises a liquid tank 2 (provided with an agitator) from which a pump delivers the liquid to the nozzles 7 of manifolds 6, 6, while a fan 16 blows a large volume of air at high speed through ducts having deflectors or baffles 37 oscillated continuously about their pivots 37a. The amplitude of oscillation of each baffle or group of baffles may be varied by adjusting the length of the link 25 of the lever and link system 24 to 27 driven by an eccentric pin 23 rotated by belt from the fan shaft. Other fixed or adjustable baffles may be added outside the oscillating baffles to direct the air stream to any desired angle. The nozzles direct the liquid into the air stream. Low pressure nozzles which give a wider cone of liquid are placed at right angles to the air stream, while high pressure nozzles with a narrow cone will move over the spray in the same direction as the air stream. The machine may be modified to spray powder with or without the addition of a liquid wetter or sticker. Such a machine, shown in Fig. 4 where a powder hopper 49 with agitator 50 delivers powder down a chute 58 into the airstream of a fan 60 while liquid supplied by a pump 38 is delivered to manifolds with nozzles 42. The powder hopper may have a slide 59 set to regulate the rate of flow. In another form, Fig. 5, a powder fan 73 delivers powder from a hopper through multiple pipes 74 with exits near the liquid delivery nozzles 65 in manifolds 64 supplied with liquid from a pump 61. The main fan 77 delivers the main volume of air as before. A screw conveyer may carry the powder from the regulator to the fan suction. One or more fans may supply the main air blast. The powder may be supplied direct to the suction of a main fan. The liquid supply to some or all of the nozzles may be stopped. The machine may be pulled by tractor or mounted on a lorry or may be self propelled, and may have deflectors to hold branches away from the air nozzle and moving parts liable to damage by the branches. The sprayed mixture may issue from the ducts outwards and upwards or outwards and downwards. The powder or the liquid may be introduced either between the fan and the baffles or outside the baffles. The Provisional Specification states that the nozzles may be mounted on spray guns to move as described in Specification 567,218, [Group XXIX]. Specifications 561,059 and 562,773, [Group XXIX], are referred to.
