Title: Arrangements employing energy pulses for guiding moving vehicles
IPC: G01S1/02
Filed: 1943-12-10
Abstract: 590,459. Radio navigation. STANDARD TELEPHONES & CABLES. Ltd. Dec. 10, 1943, No. 20747. Convention date, Oct. 8, 1942. [Class 40 (v)] A course is determined by observing by means of a cathode-ray tube on a craft, the relative phase of two trains of pulses, one of which consists of groups of pulses, transmitted from two spaced radio transmitters, one on each side of the course line. Lines of constant phase difference form a family of hyperbolµ and the desired course, corresponding to phase coincidence of the pulses at the receiver, is determined by adjustment of the transmitted phase of one pulse train. A bent course 11, 12, Fig. 1 (not shown), may be defined by two pairs of transmitters 1A, 1B and 2A, 2B, interconnected by signal channels 13, 14. A curved course 76, Fig. 4 (not shown), may be defined by two transmitters, one of which is sharply directional. The 'directive beam is caused to traverse over the course at a speed above the persistence of vision for the receiving indicator, while the tuning of the transmitted pulses is also varied by an adjustable delay line which may be of the type described in Specification 571,772, so that the path of phase coincidence of the pulses from the two transmitters is curved according to any desired pattern. Fig. 2 shows the arrangement of two transmitters 1A and 1B for producing a desired course. A generator 20 produces evenly spaced pulses 20A, at intervals of 80 microseconds, which are fed through a coupler 21 and two parallel paths 22, 23, one of which contains a delay network 24, to a combining circuit 25 and output circuit 26, to produce spaced pairs of pulses 20B and c. The pulses are fed to a modulator 28 which is supplied with radio frequency from a source 27 and spaced pairs of radio frequency pulse trains 29 are radiated from 1A. Pulses 20A are also supplied over a coupler 31 to a low-power radio link transmitter 32 which co-operates with a receiver 33 associated with the second main transmitter 1B. Transmitter 32 is preferably directional and may be replaced by a land-line link. The output from receiver 33 is fed through an adjustable delay line 34 and modulates transmitter 35 so that the train of radio frequency pulses 30 is radiated from 1B. The delay line 34 is so adjusted that when a receiver is located on the desired course line the pulses 30 appear midway between the pairs of pulses 29. The receiver 40 receives energy from both 1A and 1B, symmetrically arranged pulse combinations 50 being produced in its output when on course, and displayed on a cathode-ray tube 42, supplied with a suitable time base from generator 41 which is synchronized by the pulses. The position on the cathode-ray tube, of the pulse 63 from transmitter 1B with respect to the pulses 61, 62 from transmitter 1A is shown for the on-course position at 60, Fig. 3 ; while at 60A and 60B are shown the relative positions of the pulses for two deviations from correct course. Specifications 577,824 and 590,460 also are referred to.

Abstract: 847,636. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 30, 1958 [July 1, 1957 ; Nov. 18, 1957 ; March 13, 1958], Nos. 20783/57, 35799/57 and 8170/58. Class 39(4). A device for charging or discharging a group of fuel element channels in a reactor core comprises a rod rotatable about its axis having a passageway therethrough and enclosed within a tube which forks into a group of pipes each adapted to service a fuel element channel so that by rotation of the rod the passageway can be positioned in connection with any of the pipes. A shown in Figs. 2, 3 of the first Provisional Specification a rod 10 extending downwardly from the pressure vessel shell (not shown) is rotatable on a bearing 12 within a tube 11 welded to the shell, the tube leading into a group of four pipes 14, each pipe bearing on the moderator structure 16 through thrust plates 19 and leading into a fuel element channel 15. A passageway 22 in the rod beaks through the rod at 23 so that a fuel element introduced into the rod may be directed into a selected channel. The upper end of the rod where it terminates in the biological shield is obstructed by a pair of removable plugs, Fig. 1 (not shown) which are retained by catches. The catches can only be released after a refuelling machine has been coupled to the upper end of the tube 11 and pressurized to move a pneumatic locking member out of locking engagement with the catches. According to another arrangement described with reference to Figs. 1-7 of the second Provisional Specification (not shown), the tube forks into a group of twelve pipes arranged in inner and outer circles having, respectively, four and eight pipes. In another construction shown in Figs. 1, 2, 4 of the third Provisional Specification a reactor comprises a graphite core 7 supported on a grid 8 within a mild steel casing 9 in a pressure vessel 1. A radiation shield 10 comprising mild steel plates 23 and graphite blocks 24 is interposed between the core and a heat exchanger 11 and has passageways 28 for the passage of coolant gas. The gas is circulated by pumps 51 along routes denoted by arrows 50 and enters ports 55 in Y-branched re-fuelling tubes 36 connected to fuel element channels 29. Each tube 36 contains a rotatable shielding plug 38 and supports through struts 49 strings of fuel elements 48 in two channels 29, a passageway 43 in the plug being normally blocked by a push rod 44. To unload a particular channel 29 the appropriate plug 38 is rotated to bring the passageway 43 into alignment with the branch 37 of the tube 36 leading to that channel and the rod 44 is then removed. Loading is accomplished by reversal of the procedure, the rod 44 being utilised to move a fuel element in the passageway 43 up into the channel 29. The vessel 1 is supported by brackets 2 resting on a ledge 5 of the sheild 3 and is closed at the bottom by a radiation shield 33 comprising mild steel plates 34 and graphite blocks 35.

Abstract: 461,744. Printing processes and apparatus. WOODHEAD, H. July 24, 1935, No. 21009. [Class 100 (ii)] Inking-apparatus ; platen machines ; intaglio printing.-In the printing of bank notes &c. in colours from an intaglio or other printing-plate, a table 1 which is rotated intermittently carries one or a number of similar printing-plates, and at the stationary positions of the table 1, the plate 2 is first inked all over in a ground colour by means of inking-rollers 9 which receive ink from a distributing slab 6 supplied with ink by rollers 7 from a disc 5, roller 4, and duct 3. A pivoted doctor 10 attached to the slide carrying the rollers 9 scrapes the plate 2 as the rollers 9 recede from the plate 2. At further stations the plate 2 is inked by means of patterned pads 11, Fig. 3, which are moved first into contact with slabs 6 receiving ink of different colours by means similar to that described for the first slab. Finally, each pad 11 transfers ink to the desired part of the plate 2, and when this has received a full design in three colours an impression in multi-colour is obtained at station V on a sheet supplied by grippers which is printed by the aid of a platen or other impression member. At station VI the plate may be cleaned automatically, or by hand, prior to commencing a further series of operations. The number of colours applied may be varied.

Title: Photographic Camera
IPC: G03B15/04
Filed: 1966-05-12
Abstract: 1,154,171. Photographic cameras; photoflash sockets. EASTMAN KODAK CO. May 12, 1966 [May 24, 1965 (2)], No. 21017/66. Heading G2A. A photographic camera (10 Figs. 1, 2, not shown) having a socket assembly (15) for a flashcube (16) is further provided with means operatively connecting the film wind-means 14, 45-48 and the socket assembly to rotate a portion 28 of the socket and a received flash-cube, the operative means comprising a rotatable socket cam 45 engaging the socket portion; indexing means engaging the cam to prevent it rotating the socket assembly when a flash-bulb is in a position for an effective exposure; and slip clutch means to rotate the cam with the film wind until engagement of the cam by the indexing means. A flashcube is inserted in the socket so that the centre post (19) of the flash-cube receives a stabilizing stud 33 of the socket, a pair of lugs (20) on the centre-post being engaged by the arms of a square hair spring 32. Insertion of a flash-cube causes an ejection ring 38 and a bifurcated yoke 39 to be depressed in Fig. 3. One leg of the yoke thereby moves a member (43 Fig.6, not shown) forming part of e.g., a shutter speed change mechanism or a diaphragm adjustment mechanism, to a flash exposure control position. An exposure is then made by depressing a release button 13. Immediately before operation of the shutter, a release lever 72 moves a metering lever 68 anti-clockwise Fig. 3 and thereby displaces a metering pawl 58 sideways out of engagement with the cam 54. The pawl is also displaced forwardly by means of a spring, thereby preventing re-engagement of a lug (60, Figs. 7, 8, not shown) of the pawl with the adjacent slot (57) of the cam. Similarly, the lug (63) of a latch lever (62) is also prevented from re-entering the slot (57). After exposure, the film is wound on to the take up spool 45. As the film wind drive gear 46 is rotated, an integral clutch gear 50 rotates the socket assembly via gearing (51-53 Fig.6) until the cam 54 and assembly, have turned through 90 degrees. As the assembly reaches the limit of rotation, the metering pawl 58 and latch lever (62) engage the next slot (57). The cam and assembly are thereby latched against further rotation. Further operation of the film winding mechanism causes the friction clutch (gear 51-plate 52) to slip. The flash-cube and socket assembly may be rotated manually relative to the cam 54. To eject the flash-cube, a button 41 is depressed, thus pivoting the yoke 39 and causing the lugs (20) to move the arms of spring 32 apart. In another embodiment Figs.9, 10, (not shown) the slots (57) are replaced by teeth (76) which engage a spring (77).

Title: Improvements in and relating to electric motor control
Inventor: CARTER HOWARD FREDERICK
IPC: H02P1/20
Filed: 1952-08-22
Abstract: 736,972. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 24, 1953 [Aug. 22, 1952], No. 21138/52. Class 38 (3). An electric motor driving a vehicle has armature 10 and series-field winding 11 adapted to be connected across two sections of a battery 12, 13. Closure of a push-button switch S energizes contactors 1, 1A, to connect the motor across the two battery-sections which are in parallel, and the two sections 14, 15, of the starting resistance are included in circuit. A contact 1b of the contactor 1 closes to energize the heater element of a thermal switch TS which, after a predetermined time-delay, moves its contact to energize a contactor 2 and to discontinue the heating-current.. Closure: of the contactor 2 short-circuits resistor 14, opens contact 2a, and closes contact 2b, so that, when the thermal switch snaps back to its original position, a circuit is completed to contactor 3 and the remaining section of the starting resistance is removed. Actuation of a button switch. TB de-energizes contactor 2 and energizes contactor 4 which connects transition resistor TR between the battery-sections. The contactors 1, 1A, are opened and contactor 5 closed to connect the battery-sections in series. When the transition button TB is released, the thermal switch is again heated and the contactor 2 is closed to short-circuit the section 14 of the starting resistance. For manµuvring at low speeds, a switch M is opened to prevent the progress of operation beyond the first step on depression of the pushbutton S. The time delay of the thermal switch is determined by the value of resistor R, which, in a modification, is connected to the negative control line directly and to the thermal switch through contacts of the contactor 2, Fig. 1 (not shown). The thermal switch may embody two bi-metallic elements, each having separate contacts and mechanically connected for simultaneous operation. In this arrangement, the heating winding of the switch TS is not interrupted when the switch opens and the switch does not operate with snap-action but moves smoothly between its alternative positions, Fig. 2 (not shown). The sections of the battery may be connected permanently in series, and four sections of starting resistance used with corresponding contactors for removing the resistance in steps. The thermal switch is controlled by interlocks on the second and third contactors so that, on the restoration of the switch to the initial unheated condition, a further heating circuit having predetermined resistance is completed, whereby, after a time delay, a further contactor is closed to remove an additional section of resistance, Fig. 5 (not shown). Another type of thermal switch may be used which is generally similar to that in Fig. 2, but with the contact-making member separate from the bi-metallic elements, Fig. 7 (not shown).
Patent GB-211454-A (GB)
Abstract: 211,454. Soc. Ricard, Allenet, et Cie. Feb. 15, 1923, [Convention date]. Alcoholic liquids, distilling.-Alcohol is dehydrated by admixture with a liquid which, on distillation of the mixture, yields a constant boiling mixture of alcohol, water and added liquid and leaves a residue from which dehydrated alcohol is obtained by further distillation. The first distillate if homogeneous is treated with dehydrating agents, such as sodium or potassium carbonate and is afterwards returned to the distilling apparatus. If the distillate separates into layers, the aqueous layer may be treated with dehydrating agents or each layer may be distilled to separate a ternary mixture and to leave a binary mixture which may be separated into its constituents by distillation. Suitable liquids are hydrocarbons, alkyl chlorides, such as butyl chloride, chlorides of ethylene and acetylene, carbon tetrachloride, esters or ethers. In using ethyl acetate, a quantity of this liquid is placed in a column A heated by a coil C in the base. Alcohol to be dehydrated is supplied by a pipe B. The distillate passes to a condenser E, and the condensate is dehydrated in an apparatus K and returned to the column by a pipe N. Water and dehydrating-agent are withdrawn by a pipe M. Dehydrated alcohol is withdrawn from the base of the column A through a pipe P either in liquid or vapour form. Specifications 206,747, 213,984, 213,985, and 213,986 are referred to.
