Title: Improvements in or relating to Electrical Devices for Comparing Coded Numbers.
IPC: G05B19/27
Filed: 1966-08-12
Abstract: 1,161,127. Comparator device for digital electric data. TELEMECANIQUE ELECTRIQUE. 12 Aug., 1966 [26 Aug., 1965], No. 36261/66. Heading G4M. A comparator device is described for indicating directly which is the greater of two numbers X and Y coded in a binary chain code such as a ring counter code (Fig. 2, not shown) or a modified Johnson code (Fig. 6, not shown). In one embodiment using the ring counter code, where 1 is represented by 0001, 2 by 0010, 3 by 0100 &c. corresponding bits of each number are fed to inputs of AND gates formed by diodes d n , d<SP>1</SP>n, d<SP>11</SP>n and resistors r n  which are connected to a NOR gate formed by transistor T 1  which is then connected to an inverter T 3 . If the two numbers are identical a " 1 " (- 36 volts) is passed by one of the gates, T 1  conducts and T 2  is cut off and point F is at - 36V indicating equality. Corresponding bits of the numbers Y, X are fed to respective diodes D<SP>1</SP>n, D n  of a chain formed from diodes D n , D<SP>1</SP> n , D<SP>11</SP> n  and resistors R n  connected such that the significant bit, a " 1 " for Y or " 0 " for #X, determines the potential of the point A n . If X = 100 so that #X 3  = 0 or OV and Y = 010 so that Y 2  = 1 or - 36V then a current passes via D 3 , D<SP>11</SP> 2 , R 2 , D<SP>1</SP> 2 , A 3  is approximately 0 volts, which holds A n  at approximately 0 volts, current flowing via resistors 8, 7 from a + 12 volt supply. If Y = 100, X = 010, then a current can flow via resistors 8, 7 via the D<SP>11</SP> n  diodes, resistor R 3 , and diode D<SP>1</SP> n  thus A n  will be at a negative potential, the value depending on resistor R 3 . If T 2  is conducting, indicating an inequality, and A n  is at zero T 3  is biased non- conducting and T 4  conducts and - 36V at G indicates X, Y. If a negative value appears at An T 3  conducts, T 4  is non-conducting and - 36V at 4 indicates Y, X. If the numbers are equal OV would appear at A n  but T 2  would be non-conducting and 36V at F acts to bias both transistors T 3 , T Q  conducting so that 0 volts appears at H and G. The circuit can be used to compare a three-digit decimal number, the three digits being coded and sent to three comparator devices the outputs being connected to AND and OR gates such that where h = hundreds, t = tens, u = units. A second embodiment uses the modified Johnson code where 1 = 00000, 2 = 00001, 3 = 00011, ..., 6 = 11111, 7 = 11110, ..., 10 = 10000. In this case the inputs are applied as in Fig. 4 and four output lines are obtained, CH-4 which are coupled to the indicating circuits as shown in Fig. 5.

Title: Improvements relating to vehicle suspension systems
IPC: B60G17/015
Filed: 1964-09-07
Abstract: 1,075,481. Vehicle suspensions. M. A. MUMFORD. Dec. 3, 1965 [Sept. 7, 1964], No. 36599/64. Heading B7D. In a vehicle suspension having interconnected hydraulic suspension devices and means controlled by a pendulum to correct tilt and pitch, negative feed-back means responsive to the wheel movement are provided. Each suspension may comprise a pair of wishbone members 10, 11 pivoted to the vehicle at 12 and 19. The upper member 10 is extended to a pivot 13 to which is connected an hydraulic spring ram 14, the other end of which is pivoted to a link 16, pivoted to the vehicle at 17. A doubleacting regulating ram 18 is pivoted between the link 16 and the pivot 19. The spring rams 14 of all four suspensions are connected to a common pneumatic spring and the regulating rams 18 are connected to valves in a liquid supply system which are controlled by a pendulum operable in transverse and longtudinal planes so that pressure liquid is supplied to those rams 18 at one side or at one end in a manner so as to oppose tilt or pitch. An additional ram 26 is resiliently connected between each pair of suspension members 10 and 11 and the opposite ends of each ram 6 are connected to the opposite ends of an associated ram which acts on the liquid supply valve of the corresponding regulating ram 18 in a manner so as to oppose the action of the regulating ram 18 to damp out high frequency movements of the axle relative to the chassis. Flow restricting orifices are included in the circuit between the ram 26 and its associated valve control ram. The control valves may be disposed so that in plan they form a square, or a rectangle so as to give different correction magnitudes between tilt and pitch. In a modified system, Fig. 3, each wheel suspension comprises a pair of arms, the upper arm of which acts through a bell-crank device against a piston 34 acting in a cylinder 35 together with the piston 34 of the opposite suspension. A potentiometer 36 is incorporated in the pivot of the bell-crank lever. The spaces between the pistons 34 of the front and rear cylinders 35 are connected to a main pneumatic spring 40 and the ends of each cylinder 35 are connected to auxiliary hydropneumatic springs 37. The main spring pressure between the pistons 35 is opposed by pressure fluid supplied through lines 42 and valves 43 controlled by relays 44, the hydraulic circuit including a reservoir 47, pump 45 and pressure accumulator 46. A pendulum 50 operates a pair of potentiometers 51 and 52, one being in a horizontal plane and the other in a vertical plane, and each being in series with a pair of diagonally opposite suspension potentiometers 36 and being connected in circuit with the valve control relays as shown, so that the valves are actuated by pendulum movements to supply fluid pressure to correct tilt and pitch and a negative feedback pressure is caused by the suspension potentiometers 36.

Title: Salts of novobiocin
IPC: C07G11/00
Filed: 1956-11-30
Abstract: The invention relates to a salt of novobiocin with spiramycin complex (i.e. a mixture of spiramycins I, II and III) or spiramycin I, II or III.  It is preferred to react novobiocin in the form of the free acid with the spiramycin in the form of the free base in an organic solvent such as ethyl alcohol.  The salt may be isolated either by evaporation of the solvent or by precipitation with a liquid miscible with the solvent medium and in which the salt is insoluble, e.g. water in the case of reactions in ethyl alcohol.  The precipitation is preferably carried out at 0 DEG  to 5 DEG  C.  The salts may be prepared in an aqueous medium by double decomposition between a soluble salt of novobiocin and a soluble salt of one of the spiramycin.  The salts are synergistic in respect of the activity of the component antibiotics, they are less bitter than the spiramycins per se, they have a depot effect and an extended antibacterial spectrum. Specifications 758,726 and 785,098 are referred to.

Title: Data storage
IPC: G11C19/08
Filed: 1972-08-08
Abstract: 1436709 Magnetic storage arrangements POST OFFICE 1 Aug 1973 [8 Aug 1972] 36895/72 Heading H3B Binary information is propagated in a cylindrical magnetic domain shift register in a form equivalent to a travelling wave, propagation being effected by the interacting movement of a series of domains each constrained by a high permeability overlay pattern to move only between two stable and adjacent positions. In Fig. 4 the two permitted positions for a domain are defined by a pair of facing C-shaped overlays such as 15A, 15B, while in Fig. 5 a domain can exist at either end of an overlay bar such as 32. A series-parallel array of six overlay dots such as 54 is used in Fig. 6 to define two permitted domain locations each formed by a square of four dots, the overlay pattern in this embodiment including bar overlays 53-61 as used in Fig. 5. Each arrangement operates on the same principle which involves triplet grouping of the individual two-position domain overlays such as 31, 32, 33 and 32, 34, 35, Fig. 5, and the provision of domain shift conductors 42, 43, 44. Domains in the normal or zero positions are represented in the figures by hatched circles and are initially formed by superimposing, on the transverse bias field normally required, a smaller field pulsed with microsecond pulses at a repetition rate of about 1 kHz. Superfluous domains are then removed by a small increase in the bias field. Operation of the register involves pulsing conductor 42, Fig. 5, so that a domain is displaced to the opposite end of overlay bar 31. Conductor 44 is then pulsed by a positive pulse which displaces the domain in bar 33 and is then negatively pulsed to restore the bar 33 domain to its initial position. As the domains of overlay bars 31, 32, 33 are immediately adjacent during the positive pulse period, mutual repulsion causes the domains of bars 31 and 32 to be transferred to the opposite bar ends. Conductor 43 is then pulsed in the same manner as conductor 44 with the result that the domain of bar 35 is moved into proximity with the domains of bars 32 and 34. Mutual repulsion again takes place, and this time the domain of bar 34 is transferred to the opposite end of the bar. Subsequent interaction of the domains as the conductors 44 and 43 are alternately pulsed, steps the input signal from conductor 42 as a travelling wave of domain displacement from left to right through the register. A suitable magnetic material for supporting the domains is stated to be a layer of magnetic garnet such as Eu 1 Er 2 Ga 0À7 Fe 4À3 O 12  on a non-magnetic substrate.

Abstract: 924,398. Ram-Jet engines. DAIMLER-BENZ A.G. Oct. 27, 1960 [Oct. 31, 1959], No. 36952/60. Class 110 (3). A fuel control and supply system for a ram jet engine rotating about an axis offset from the engine, more particularly for a ram jet disposed at the tip of a rotor blade of a helicopter, comprises means for delivery of fuel to the engine burners by centrifugal force produced during operation and a fuel control device which meters the fuel including a speed governor the centrifugal system of which forms part of the rotor and includes the moving part of the fuel control device. Ram jet engines 30 are mounted on the ends of rotor blades 13 disposed on a rotating rotor casing 11 supported by an engine frame or aircraft fuselage 12. Fuel supply pipes 14 extend horizontally above the blades 13 and are secured to the casing 11 by a screwthreaded socket 15 by means of which the position of a guide bush 16 may be adjusted axially in relation to a control plunger 17. The forward edge 17<SP>1</SP> of the plunger 17 controls one or more fuel-metering bores 18 in the bush 16. The plunger 17 is connected by a rod 19 to one arm 20<SP>1</SP> of a bell-crank lever 20 pivoted on the casing 11. The other arm 20<SP>11</SP> of the bell-crank is pivoted to a thrust rod 21, the other end of which bears against a spring cap 22 formed with fuel flow apertures 23. A speed-selector spring 32 which bears against the spring cap 22, is loaded by a speed selector lever 37 which acts through a bearing 37<SP>1</SP>, a sliding bush 34 and spring 35 on the spring cap. In the stop position, the lever 37 is vertical and the bush 34 is urged by the spring 35 against the aperture 37<SP>11</SP> so that the fuel supply is completely stopped. As the lever 37 is pivoted, the spring 35 is stressed so that the plunger 17 moves to the right and completely uncovers the bores 18. Fuel is then supplied to the engine burners 29. The rotor accelerates and the centrifugal forces on the bobweights 38 and plunger 17 increase until they balance the loading on the spring 32 when the plunger edges 17<SP>1</SP> start to reduce the area of the bores 18. Stops 24, 25 determine the idling and maximum speeds of the rotor. The fuel from the pipes 14 is fed to the rotor blades 13 through pipes 27. Gaps are provided between the pipes 27, 29 which are open to atmosphere through ports 31. By this arrangement, the fuel supply to the burners 29 is made proportional to the rotational speed.
