Title: Improvements in and relating to centralised traffic control
IPC: B61L3/22
Filed: 1963-11-06
Abstract: 1,064,377. Automatic train control. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 6, 1963 [Nov. 6, 1962], No. 43898/63. Heading B7N. An arrangement for controlling rail vehicles from a central control office comprises means for transmitting from each vehicle to the central office information relating to vehicle position, speed, length &c., means at the central office for processing this information and for transmitting instructions for vehicle control. A signal at frequency # 1 generated in unit 2 at the central office is applied via amplifier 3 and a coupler 4 to a line 1 disposed adjacent the vehicle track. The signal is picked up by aerial 5 on a vehicle and applied via coupler 6 and amplifier 7 to a unit 8 which is tuned to frequency # 1 and includes means for producing an output signal each time the signal drops to zero, i.e. each time the vehicle passes a crossover point in the line 1. These signals are counted by counter 9 which applies a " location " signal to a binary coding device 10 which is also supplied with information relating to vehicle speed, acceleration, length &c. The output of the coding device modulates in unit 13 a signal at frequency # 3  generated in unit 12 and the modulated signal is amplified in unit 14 and applied via coupler 6 and aerial 5 to the line 1. This signal is received at the central office and applied via coupler 4, amplifier 15 and filter 16 to a data transformer 17 which supplies the information data in binary form to a storage device 19. A data processing device (not shown) derives from the stored information command signals for control of the vehicle and these are applied via the store to a coding unit 20 which supplies an output to modulate in unit 22 a signal at frequency # 2  generated in unit 21. The modulated signal is transmitted via amplifier 3 to the line and applied via aerial 5, amplifier 7 and filter 23 to decoding devices 24, 25 which supply signals for control of the vehicle.

Patent GB-441260-A (GB)
Abstract: 441,260. Closed stoves and furnaces. ZIEGELMEYER, H., Leobersdorf, Lower Austria. Aug. 9, 1935, No. 22548. Convention date, Aug. 17, 1934. [Class 126] [See also Group XII] In a closed stove or furnace, the gases distilled from the fuel in the shaft A pass through a perforated partition T to the passage G formed between it and the shaft wall, where they are mixed with primary air passing to the top of the passage. The mixture passes to a mixing chamber B to which pre-heated secondary air is also supplied, in the case shown from a passage Z. The gaseous mixture leaves the chamber B through nozzles or openings C, which may be controllable by slides P, the choking effect causing more intimate mixing and better combustion of the gases. In a modification the mixing-chamber B is formed by the lower end of the passage G, to which secondary air heated by passage under the grate is supplied.

In Fig. 1 the meter 1 comprises a bulb 2 filled with an electrolyte which is initially yellow but turns green when the predetermined distance is reached. The bulb 2 is connected to the output of a tachometer 5 via a high value resistor 4 the ohmic value of which determines the distance before colour change. The tachometer includes a speed responsive member 6 of inductive, capacitive, or galvanic type feeding a monostable multi-vibrator 7 connected to a moving coil meter 8 which indicates the momentary speed of the vehicle. In Fig. 2, the electro-chemical amp-hour meter l'includes an electrolytic cell 9 the resistance of which increases sharply when the predetermined distance is reached. This triggers a threshold switch 10 to energize a lamp 11. The digital signal of the tachometer 5 is converted to an analogue signal by an RC element 12. In Fig. 3 the meter I includes an electrolytic cell 13 comprising a tube 14 with mercury electrodes 15, 16 separated by an electrolyte 17 (an aqueous solution of an iodide salt and mercuric iodide). The electrolyte band 17 moves across the tube 14 in proportion to the distance travelled, a full traverse being arranged to correspond to the predetermined distance. A changeover switch 18 reverses the current through the cell 13 for re-use. The meter 1, 1', or 1" may be accommodated in a normal vehicle tachometer.

Abstract: 1,062,948. Centrifugal pumps. SPEEDWELL RESEARCH Ltd. Nov. 2, 1964 [Nov.19, 1963; June 25, 1964], Nos.45545/63 and 26251/64. Heading F1C. In a centrifugal pump having an open impeller for pumping mixtures of gas and liquid, such as air and milk, the centrifugal radial component of the liquid velocity in the pump casing is greater than the centripetal radial component of velocity of the gas bubbles. Preferably the liquid velocity at any point is greater than 0À75 ft./sec. Formulae are given in the Specification for calculating the absolute pressure of the liquid at the impeller blade tips, the centrifugal liquid velocity, the centripetal bubble velocity and the radius R Be  at which these velocities are equal. In theory, in order to avoid vapour lock the radius of a gas cavity 47 which forms at the centre of the impeller must not exceed the radius R Be . However, the distortion 48 of the cavity 47, in the vicinity of the outlet must be taken into account, which distortion increases when the size of outlet is decreased, as shown in dash lines. There is no pressure recovery in the liquid in the pump outlet duct 41. A nozzle 42 in the duct 41 prevents pressure recovery in the liquid immediately downstream relative to the liquid immediately upstream. The outlet slot has a dimension parallel to the impeller axis equal to the casing width and a dimension D at a maximum value of 0À423 R 1 , the nozzle 42 being positioned downstream of the cutwater 53 a distance E of not less than D-d.

A wrapper 50, Fig. 2, folded to form an angular container over-lies a strip 56 adhered to the entire length of the edge of the container and extending out through a slit 54a, 54b in the container at one end 58 to form a tab for opening the container. In the form shown the wrapper is folded about a mandrel 52 into which cigarettes are introduced through a funnel (84), Fig. 7 (not shown) so that they push against the bottom of the package thereby ejecting the package and cigarettes from the mandrel. The top closure flaps, adhered together and to the strip 56, are opened by pulling the end 68, thus tearing the closure along half the length of the upper edges to form a flap (103), Fig. 15 (not shown), hinged about an upper end edge. The flap (103) is reclosable by adhesive either on the underside of the strip or on the upper surface of the intact half of the end closure. The wrapper may comprise a laminate of foil and paper. The slits 54a, 54b may be sealed by tabs on the inner surface of the wrapper, Figs. 18, 20 (not shown), or by a single strip that runs the length of the wrapper between the two slits, Fig. 21 (not shown). In a further embodiment, one or two sheets, e.g. of cardboard (118), Fig. 22 (not shown), placed between strip 56 and wrapper 50 extend around the top, bottom and side faces of the package to impart rigidity to the package. The sheet has slits (121) (123) displaced from the slits 54, and when forming the top closure of the package the end 68 of the strip passes through slits (121) (123) and lies between the sheet and wrapper 50 until it passes out between slits 54. Alternatively the sheet (118) may be of flexible material and strip 56 may lie between the sheet and wrapper. Again, Fig. 24 (not shown), a similar reinforcement sheet (128), adhered to the wrapper 50, has a series of projections at each end which interlock at the top closure when the wrapper is folded around the mandrel. After opening, the top closure member may be reclosed by folding the protruding end of the strip 56 and tucking it under the adjacent other end, Figs. 39-41 (not shown). The sheet 128 may be in two parts and the filled package may be withdrawn from the mandrel by grippers.

Abstract: 1,099,156. Feeding webs. HUNTER DOUGLAS INTERNATIONAL Ltd. Nov. 8, 1965 [Nov. 10, 1964], No. 47199/65. Heading B6B. In an arrangement for controlling the size of the step in a step-by-step feed mechanism for a web, a continuous drive means 10 operates web feeding means 3 via a correction device 5, comprising a member 12 whose movement can be variably restricted by the selective interposition of different abutment means 26, the connection between the drive 10 and the mechanism 5 comprising links so arranged as to enable continuous running of the drive means, despite the interference of the abutment means. Thus the drive rod 8 is connected to the link 13 by pivot 14 and the link 13 is connected to the base 11 carrying the member 12 via a bearing 15. Thus with the pivot 9 in the lower position and the member 12 to the extreme right, the bearing 15 is above the axial line of the link 8, but the link is restrained from clockwise rotation by an abutment 35. When the rod 8 moves upwardly and to the left, the axis of the link 8 rises above the bearing 15, but the link is restrained from anticlockwise rotation by the tension effect of spring 16 which pulls down on the pivot 14. When, however, the member 12 strikes an abutment 26, the rod 8 is enabled to continue its leftward motion by the anticlockwise rotation of the link 13 against the tension of the spring 16. The selective interposing of differently positioned abutment faces 26 is controlled by levers 22 moved by electromagnets 27, which may be operated from a control circuit in accordance with the output of a photo-electric cell which scans marks on the web. The web-feeding device 3 may comprise a free-wheel device arranged to operate in one direction only as a result of the reciprocatory movement of the rod 4, whose effective length may be varied at 30 to vary the size of the step.
