Patent GB-860793-A (GB)
Title: Device for controlling and coordinating the controls of an aircraft
Inventor: EGGERS GERHARD
IPC: G05D1/08
Filed: 1958-04-11
Abstract: 860,793. Automatic steering-control systems. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. April 11, 1958 [April 17, 1957], No. 11610/58. Class 38 (4). Aerodynamic steering controls of an aircraft are rendered inoperative by the pilot during substantially vertical flight when the angular attitude of the aircraft is automatically controlled by control of a jet, and rendered operative by the pilot during substantially horizontal flight when the automatic control is inoperative. In Fig. 1, D.C. signals of reversible polarity, derived from a potentiometer-type pick-off (not shown) in a bridge circuit associated with a gyro 34 responsive to the pitch attitude of an aircraft during vertical take-off, are applied through a magnetic amplifier 11 to control an A.C. servomotor 9 which adjusts, through fluid-pressure servo-systems 8, jet spoilers 5 in opposite directions to maintain a desired vertical attitude. Positional and rate follow-up signals derived from movement of the jet spoilers are applied to amplifier 11 through channels 15 and 17, the latter including a resistance-capacity delay unit 42. Signals from a rate gyro 35 are also applied to amplifier 11. The desired attitude may be trimmed by signals applied to amplifier 11 in consequence of movement of a manual controller 31. Change from vertical to horizontal flight is effected by moving switches 41 to position b and closing a switch 40. Gyro 34 is thus disconnected and a fixed signal introduced for a predetermined time from a source 38 to cause a predetermined rate of change of pitch until the aircraft is level. Manual controller 31 is now also effective to trim the pitch by signals applied to an amplifier 10 to control an A.C. servomotor 4 which adjusts, through a fluid-pressure servo-system 3, a control surface 1. Positional follow-up signals derived from movement of control surface 1 are applied to amplifier 10 through a channel 14. Finally, to continue horizontal flight, switches 41 are moved to position c to cut out delay unit 42. Change from horizontal flight to vertical flight prior to landing is effected by returning switches 41 to position band operating manual controller 31 to produce nose lifting. Vertical flight may then be maintained automatically by moving switches 41 to position a to reintroduce gyro 34. Signals to control control-surface 1 may alternatively be derived from the spoiler control system or both control systems may be controlled by separate automatically-produced signals.

Title: Improvements in and relating to the production of aliphatic per-acids
IPC: C07C409/24
Filed: 1963-03-25
Abstract: Peracids of lower, saturated aliphatic carboxylic acids having from 1-3 C atoms are made by reacting hydrogen peroxide with the corresponding aliphatic acid in the ratio 0.3 to 5.0 moles hydrogen peroxide/mole of acid at 20-80 DEG  C. in a reaction mixture containing 5-20% by weight of a strong, water-entraining acid, and 20-75% by weight of water and vaporizing together from the reaction mixture, at a pressure of 15-350 mm. of mercury, and a temperature of 20 to 80 DEG  C. a product containing peracid, aliphatic acid and water.  The process may be operated batchwise or continuously. In the continuous process the hydrogen peroxide, aliphatic acid and water, are continuously added to the reaction mixture, the hydrogen peroxide and lower aliphatic acid being added in the proportions of 0.30 to 1.1 mole hydrogen peroxide/mole acid, the concentrations of water and water-entraining acid being maintained at 20-75% and 5-20% respectively.  The reaction is carried out at a pressure of 15-350 mm. of mercury, and the product is continuously distilled off.  The reaction will normally take place in 10 minutes to 1 hour, preferably 10 to 30 minutes.  Suitable water-entraining acid substances are sulphuric acid and other strong acids which boil above 150 DEG  C. at atmospheric acid, and alkyl and aryl sulphonic acids, trifluoroacetic acid, and cation-exchange resins, e.g. sulphonated styrene-divinylbenzene copolymers. Sodium sulphate, molybdenum sulphate or calcium sulphate together with a strong acid which boils above 150 DEG  C. may also be used. The hydrogen peroxide is normally introduced as an aqueous solution and may be used in a concentration of 20-100%.  Comparative examples are given in which 1% sulphuric acid is used as water-entraining acid.

Title: Improvements in or relating to transistor circuit arrangements
Inventor: STEPHENSON WILLIAM LAWRENCE
IPC: H03K4/56
Filed: 1954-04-23
Abstract: 762,526. Sawtooth and pulse transistor circuits. MULLARD RADIO VALVE CO., Ltd., March 29, 1955 [April 23, 1954], No. 11832/54. Class 40(6) In a circuit having a capacitor connected between the collector circuit and the base of a first transistor to provide negative feed back of the Miller type, a second and third transistor are arranged in a trigger circuit including the capacitor, the second transistor also being included in the collector circuit of the first to interrupt the negative feed back in response to a signal applied to the base. Assuming transistor 2 to commence conduction, the potential at A rises applying over the Miller capacitor 5 a potential rise to the base of transistor 3, the diode 6 preventing transistor 3 from being completely cut off. The fall in potential of the collector of transistor 3, curve C, is fed over coupling capacitor 4 and resistor 7 to the base of transistor 2, curve D to complete a positive feed back loop so that transistor 2 is held in saturation. During the forward stroke the current passed by the emitter of transistor 3 increases, the potential rising curve B and the current through transistor 1 also rising correspondingly. At the end of the forward stroke, transistor 1 bottoms with the result that the collector of transistor 2 cannot rise further in potential. The base of transistor 3 therefore commences to fall and due to the positive feed-back loop transistor 2 cuts off as the potential of point A falls, and the base, curve D, rises. The circuit remains in this condition until the charge on capacitor 4 has changed sufficiently for transistor 2 to conduct again and the cycle repeats. The R.C. coupling 4, 7 may be replaced by D.C. coupling so that the circuit has a single stable stage and when triggered passes through a cycle and back to its original state. A sawtooth output may be derived from the join of transistors 1, 2 at the point E.

Patent GB-587781-A (GB)
Title: Improvements in and relating to protective arrangements for ring main systems
IPC: H02H7/28
Filed: 1944-06-22
Abstract: 587,781. Protective cut-out systems. ELECTRIC TRANSMISSION, Ltd., and DANNENBERG, K. June 22, 1944, No. 11908. [Class 38 (v)] An open or closed ring main system, or a spur thereof, is protected by low-rating fuses in the ring on each side of each tee-off in each phase. The protective unit 1, shown in Fig. 2, has a fuse 4 normally shunted by a closed circuit 6. When a fault current flows towards the tee-off, a wattmeter type relay 13, energized by current and potential transformers 7, 8, opens a normallyclosed switch 12 which shunts a relay 10 in the current-transformer circuit, thus energizing the relay 10 and opening the circuit 6. The relay on each side of the tee-off is only sensitive to power passing through it towards the tee-off, and by grading the speeds of operation of the units by means of the transformer ratios, the time constants of the trip relays, or the wattmeter-relay responses, the number of fuses blown is reduced to a minimum. To protect against unbalanced conditions the wattmeter may be replaced by the parallel connected secondaries of current transformers so that the relay 10 is only energized when there is an out of balance current between the phases. In small open ring main systems, the wattmeter can be dispensed with, Fig. 3 (not shown) and the trip relay 10 operated directly from the current transformer. Further, in case the line is energized from each end, the protective devices are placed at each side of each tee-off as in Fig. 2, and grading ensures that those farthest from the supply operate first. At each location a heavy fuse 2 is connected in series to operate on heavy overload or on failure of the relay. The trip relay, Fig. 4, comprises the explosive unit 10, which may be of the construction described in Specification 563,849, operating the striker 14 when energized by the current transformer. The oil-filled switch 6 mounted in parallel with the fuse 4 on conductors 22 comprises a tag 23 carrying a knife 28 and connected by silver elements 27 to a yoke 29 which is held against spring-action 30 by a latch 32. When the striker operates the latch, the yoke descends, severing the elements 27 and bringing the fuse 4 into operation. The operation of any striker may clear all phases at isolator I'.

Convention date, April 19, 1929. [Class 40 (ii).] Means for ensuring a uniform feed of a sound film as it passes the recording or reproducing point comprises a sprocket drive 3 and a drum drive 5 the sprocket being positively driven from the shaft 6 whilst the drum is frictionally driven at a variable speed by a resiliently tyred wheel 18 the pressure of which against the drum-driving member 14 is varied by an idler-pulley 32 which bears against a loop in the film between the drum and sprocket. The idler pulley is connected to a strap 28 adjustably mounted on an eccentric bush 20 for the wheel 18 the latter being driven by pins 38 eccentrically mounted on planetary pinions 36 carried by an arm 35 on the drive shaft 6. The pinions engage a fixed wheel 37 of equal size attached to the eccentric and the pins 38, which engage radial slots in the wheel 18, have an eccentricity equal to that of the eccentric 20 to ensure a uniform angular velocity of the wheel 18. When starting up, a pivoted stop 42 for the idler pulley prevents engagement of the tyre 19 with the driving wheel 14 until the working speed of the film is attained.

[Also in Division B8] In a method of making packages by heating and stretching a plastics foil in moulds so as to form at least one row of containers and conveying the interconnected containers to subsequent filling and closure stations, those parts of the moulding and closing stations which would otherwise interfere with the feed motion are withdrawn at an angle to the feed direction so as to permit feed conveying. Preferably the containers are of the type shown in Fig. 6, with outwardly directed neck flanges 11 with peripheral constrictions 12 immediately beneath and parallel to them. As described, a web 1 is drawn off a roll 3 past a heating station 4 (not described), through a moulding station 7 where pockets are formed, through a filling station 9, a closure station 13 where a closure web 14 is applied; the packages are separated at a station 16, and delivered to a conveyer 17. At the moulding station 7, see also Fig. 4, the web is pre-stretched by plungers 22 and the stretching completed by a vacuum applied through vents 30 or compressed air through conduits 37. The transverse walls 26 of the moulds are then outwardly removed to allow further conveying between guides of the formed containers which, as shown in Fig. 6, are joined at their flanges 11. At the closure station 13, where a top web is heat sealed over the container mouths, the transverse walls 15 of the container holders are similarly removable to allow subsequent feeding, Fig. 5 (not shown). Fig. 7 (not shown) illustrates a mould for forming containers with triangular bases. In this case the longitudinal walls (25a) form the walls of the triangles together with removable walls (26a), (26b). the latter pairs of walls being inclined to the longitudinal direction at angles less than 90 degrees. The walls (26b) have vertical slots to accommodate the walls (26a) where these pairs intersect, the walls (26b) being inserted first.
