Title: Improvements relating to communication circuit arrangements
IPC: H04Q3/00
Filed: 1965-09-23
Abstract: 1,123,190. Automatic exchange systems. TELEFONAKTIEBOLAGET LM ERICSSON. 23 Sept., 1965 [23 Sept., 1964], No. 40671/65. Heading H4K. For supervision over a junction, the incoming relay set FIR includes two so-called memory elements Ma, Mb each of which has a low and a high resistance state and is changed from one to the other by characteristic current pulses, while the outgoing relay set FUR has bridged across the loop a two-state threshold element T. Semi-conductor elements having the required properties are described in Specification 1,070,411. In the normal condition, current flows over the junction, all the elements being in the low resistance state, and relay R1 is operative to apply positive potential to the C wire. This is removed if the junction is faulty. When the junction is seized by marker Mka, relay R2 energizes and cuts out part of the winding of R1, so that marginal relay R3 pulls up at the incoming end, whereupon marker Mkb operates to effect the connection to a link circuit SNRB. Mkb also connects pulses P1 having a steep trailing edge to change the elements Ma, Mb to the high resistance state, so that T also change? to that state. Relays R1, R2, R3 relapse and the junction is marked busy. Relay 1R is operated from Mkb to establish a talking connection. Upon release when feed relay SMR2 falls back, 1R restores and pulses PN having a sloping trailing edge are connected to restore Ma, Mb and hence T to the low resistance state.

Title: Printing unit for use with thermally sensitive record material
IPC: B41J2/345
Filed: 1963-10-16
Abstract: 973,200. Selective printing. NATIONAL CASH REGISTER CO. Oct. 16, 1963 [Nov. 1, 1962], No. 40865/63. Heading B6F. A high-speed printing unit for use with thermally-sensitive record-material comprises a member of insulating material having a number of resistance elements thereon each connectible to a short duration electrical pulse, selective connection of the elements to the pulse causing marking of the record material to produce required characters or numerals. As shown in Fig. 2, a unit for printing one character comprises five wafers 10 separated by dielectric spacers 50, each wafer having on its edge seven resistance elements 1A ... 7A, 1E ... 7E, so that selective application of the pulse to certain of the elements causes a series of marks on the record material to make up the required character. Alternatively, a single wafer 10 with elements 1A ... 7A may be employed, and the record material in strip form fed across the edge of the wafer, successive columns of marks being made on the material by the elements to make up a required character. The conductors to the elements may be on one face of the wafer 10 and a common return lead or separate return leads may be on the opposite face. In a modified form of the arrangement shown in Fig. 2, instead of each resistance element being completely separate from the others, each horizontal row 1A ... 1E or each vertical row such as 1A ... 7A may comprise a strip 78, Fig. 7, with a series of spaced conducting wires 85 ... 90 connected to its back at equal intervals, the stays being heated only between two such wires selectively connected to the pulse to cause a mark or marks to be made. A number of units, Fig. 2, may be assembled in a single line or in a number of lines for line or page printing respectively.

Title: Improvements in or relating to Rocket Engines
Inventor: HEALEY GORDON TERRY
IPC: F02K9/58
Filed: 1968-08-31
Abstract: 1,183,270. Rocket engines. ROLLS-ROYCE Ltd. Aug.31, 1968, No.41707/68. Heading F1J. A rocket engine comprises a combustion chamber or reaction chamber, duct means for flow of propellant from a source thereof to the combustion chamber, and inflatable means which acts to obturate the duct means when inflated. The rocket engine shown comprises an inner casing 12 which defines a fuel storage compartment 22, an oxidizer storage compartment 20 and a combustion chamber 68, the casing 12 comprising a first cylindrical portion 16, a radial portion 19 and a second cylindrical portion 18, there being openings 24, 26 through the casing portions 16, 18 which are initially closed by frangible seals 28, 30. A piston member 32 comprising a first portion 34 and a second portion 36 is disposed within the portions 16, 18 of the casing being initially disposed in the position shown, the seals 28, 30 being received within annular grooves 38, 40 formed in the piston portions 34, 36 respectively. The piston is formed, with bores 42 which communicate with a central bore 44, the bore 44 communicating with an annular chamber 46 which in turn communicates through radial bores 48 with an annular chamber 50 which is open to the combustion space 68. An inflatable member 70 is disposed within the annular chamber 46, the member being connected to a source of pressure through bores 76 and 74, a valve 78 being disposed within the bore 76, the arrangement being such that when inflated, the member 70 closes off the bores 48. The piston 32 is also formed with an annular groove 56 which communicates with an annular chamber 60 which in turn communicates through radial bores 62 with the annular chamber 50. An inflatable member 72 is disposed within the annular chamber 60, the member being connected to a source of pressure through the bores 76 and 74, the arrangement being such that, when inflated the member 72 closes off the bores 62. To initiate operation fluid under pressure is caused to pressurize the fuel and oxidizer storage compartments and also acts on the piston 32 which is moved to the right until it abuts the flange 80, such movement breaking the frangible seals 26, 24 and placing the fuel compartment 22 in communication with the groove 56 and the oxidizer compartment 20 in communication with the bores 42. Thus fuel discharges through bores 62 into the combustion chamber and oxidizer through bores 48, the resulting combustion gases discharging through the propulsion nozzle, not shown. The valve 78 in this phase of operation is closed so that the members 72 and 70 are not inflated. To stop the operation, the valve 78 is opened whereupon fluid under pressure in the chamber at the left of the piston 32 pass through ducts 76, 74 to the members 72, 70 which thus inflate and close off supply of fuel and oxidizer to the combustion chamber. The invention may be applied in the case of a monopropellant type rocket in which the propellant is hydrogen peroxide.

A heat-sensitive material in liquid form such as fruit or vegetable juice, beer, wine, coffee, milk, or resin or pharmateutical (antibiotic) in liquid form, is stabilized by subjecting it to a first stripping operation wherein an inert gas such as nitrogen, argon, hydrogen, helium or carbon dioxide, is passed through the material to displace substantially all the dissolved ogygen, increasing the temperature of the stripped material, removing volatile essence from the material by subjecting it to a second stripping operation, stabilizing the material from which the essence has been removed by increasing the temperature of the material, and then combining the essence and the stabilized material, the essence and the material being continuously maintained under non-oxydizing conditions throughout all process steps subsequent to the oxygen removal step. In preferred procedure the oxygen content of the material after the first stripping operation is to be less than 0.4 part per million, the temperature to which the material is heated after the first stripping operation is no higher than 88‹C., the material, after its stabilization by heating, is rapidly cooled before re-combining it with the essence, and the removed essence is recovered by introducing it into a body of stabilized material of substantially the same composition as that of the material from which the essence has been removed.

Title: Improvements in or relating to the manufacture of pure benzene
IPC: C07C7/00
Filed: 1961-12-04
Abstract: Benzene having a solidification point of 5.4 DEG  C. or above is obtained from a hydrocarbon mixture also containing naphthenes, e.g. cyclohexane and methylcyclohexane, and possibly n-heptane by (1) distilling at normal or reduced pressure to separate a fore-runnings containing benzene-cyclohexane azeotrope and additional quantities of benzene; (2) subjecting the fore-runnings from step 1 to catalytic reforming to increase the benzene content and adding the reformate to the feed to step (1), and (3) distilling the bottoms from step (1) at superatmospheric pressure, e.g. 2-20 atmospheres to recover pure benzene overhead and as bottoms methylcyclohexane, n-heptane and higher boiling aromatics.  If desired, toluene may be recovered from the bottoms from step (3) by a 2-stage distillation, the first at normal or reduced pressure to remove fore-runnings which may also be reformed and the second at increased pressure to obtain pure toluene overhead. The feed may be a pressure refined coke oven benzene, or a benzene cut from a catalytic reformate (in which case the benzene fore-runnings are reformed in the main reactor) or from a pyrolysis gasoline.  If sulphur compounds are present in the hydrocarbons or hydrogen, reforming is effected over a sulphur-resistant catalyst, e.g. cobalt molybdate.  In the absence of sulphur, platinum may be used.
