Title: Improvements relating to Printing Apparatus
IPC: B41M1/12
Filed: 1966-06-06
Abstract: 1,187,763. Electrostatic printing apparatus. MOLINS MACHINE CO. Ltd., D. T. N. WILLIAMSON and M. A. PYM. 5 June, 1967 [6 June, 1966], No. 25120/66. Heading B6C. Apparatus for printing on a container of electrically non-conductive material which contains an electrically-conductive foil as an inner wrapper for goods packed in the container comprises a first electrode arranged a small distance away from the surface to be printed; means for supplying electrostatically charged ink between the electrode and the surface; a second electrode applying potential to the foil; and means for creating a potential difference between the two electrodes so that the ink is propelled on to the surface of the container. Fig. 1 illustrates a cigarette packet 1, with a hinged lid, containing cigarettes 2 wrapped in metal foil 3. A first electrode, in the form of an intaglio plate 4 with raised portions 9 and recessed portions 10 is placed parallel to a surface of the packet and with a small gap therebetween. At the open end of the packet 1, a probe 6 is held in contact with the foil 3, and a D.C. source 7 with switch 8 is connected across electrode 4 and probe 6. A dry particulate ink is deposited in the recesses 10 and is electrostatically charged, either by corona discharge or by connecting a voltage source (e.g. source 7) to electrode 4 in the case of a conductive ink. Creation of a potential difference between foil 3 and electrode 4 causes migration of ink particles to the surface of the packet where they can be fixed. The probe 6 may be fixed, or may be movable towards and away from the container; alternatively, the second electrode may be a plate 6A placed to induce an electrostatic field to foil 3, the container lying between plates 4 and 6. The ink supply may be combined with the first electrode by including an ink reservoir with conductive walls serving as the first electrode with a stencil screen lying between the reservoir and the container; the ink supply may also be formed on a temporary support acting as the first electrode, e.g. an intaglio plate, a gravure plate, an offset roller or a sheet of photoconductive or internally polarized material. In Fig. 2 (not shown), a conveyer belt carries the containers past the printing station; the foil of each container is engaged either by a reciprocating probe or a swinging roller.

Filed: 1949-10-01
Abstract: 662,398. Vehicle undercarriages. DAIMLER-BENZ AKT.-GES. Oct. 1, 1949 [Nov. 2. 1948], No. 25283/49. Class 108(ii) The main spring masses of a motor vehicle, e.g. engine. petrol tank, spare wheel, are offset from the centre-line of the vehicle in such a way as to cause the vehicle, when empty to lean away from the driving side, and to lean in the opposite direction when occupied by the driver only. The distance of the centre of gravity from the centreline is preferably so arranged that the tilting movement about the centre-line caused by the weight of the empty vehicle is approximately half that caused by the weight of the driver. Fig. 3 represents empty vehicle with its centre of gravity offset whereby the weight of the vehicle G causes the body to tilt by an angle # away from the driver's side, with the preferred arrangement mentioned above. when the driver occupies the left-hand side, the body tilts by an angle # in the opposite direction, and when one passenger is also present next to the driver the tilt is # in the original direction as shown in Fig. 3. With a vehicle which is level when empty, entry of the driver would cause a tilt of 2 #.

Abstract: 1,090,323. Discharging glass sheets from roller conveyer. LIBBEY-OWENS-FORD GLASS CO. June 15, 1965 [Aug. 3, 1965], No. 25322/65. Heading B8A. Glass sheets 13 carried on individual tables 11 conveyed by an endless conveyer, not shown, are transferred to driven roller conveyer 73 by suction pads 47 whilst the tables 11 continue to the right as shown. Suction pads 47 are carried by trolley 38 moving on rails 37, the trolley being returnable by pusher 64 operated by fluid cylinder 67. Operation.-Each table 11 carries lug 15 which strikes a valve to initiate a cycle of movement. This causes air cylinder 30 to move downwards plate 28 pivoted at 27 to engage suction pads 47 at 51 and to depress them into contact with the upper surface of sheet 13. The pads grip the sheet and as the sheet is conveyed rightwards by plate 11 the carriage 38 is dragged rightwards with it so that the sheet is partly lifted upwards to move over the upper surfaces of the rollers of roller conveyer 73, at which stage the trolley 38 engages valve 60 to release the sheet on to the roller conveyer by cutting off the suction. Trolley 38 then engages valve 61 which brings into operation pusher 64 which pushes the trollery carrying the suction pads 47 back to its original position. Pusher 64 engages valve 70 to restore itself into position. Each sheet 13 therefore is lifted off its table 11 and transferred to and conveyed by roller conveyer 73.

IPC: H01P1/213
Filed: 1948-10-01
Abstract: 655,146. High-frequency electric filters. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 1, 1948, No. 25561. [Class 40 (viii)] A band-pass circuit comprises two parallel sequences of transmission line sections connected in series, and each section has an electrical length of one quarter-wavelength at a frequency within the band and an impedance connected across it at the output end thereof, the sequences being each terminated by a resistive load. As shown in Fig. 3, an aerial feeder for a carrier wave transmitter comprises two sequences of such line sections, both connected to a generator 45 and one also connected to an aerial and the other to a resistive load. The constants of this filter can be arranged so that it presents a constant resistive impedance to the generator throughout a range of frequencies. As can be seen from the positions of open and closed stubs the two sequences bear an inverse relation to each other. Fig. 4 shows a modification in which the input is by a line 47 and the aerial is connected at output 56 and a resistive load at output 59. A stub 48 is added to the input line to minimize error due to imperfect cancellation of stray impedances.

Title: Method of and apparatus for storing and dispensing liquefied gases
IPC: F17C13/02
Filed: 1947-09-22
Abstract: 643,035. Gas-dispensing apparatus. LINDE AIR PRODUCTS CO. Sept. 22, 1947, No. 25766. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 3, 1948]. [Class 8(ii)] [Also in Group XXXVI In a vessel 10 for liquefied gas anr having valved conduits 26, 24 for liquid and gas withdrawal respectively delivering to a vaporizer 27 and a superheater 32 and thence to a service connection 34, the conduit valves 29, 41 are actuated by means e.g. solenoids 30, 42 controlled by a device e.g., switches 22, 23 responsive at predetermined low and high pressures in the vessel 10 to open valves 29, 41 and having means such as a switch 44 to prevent operation of the solenoid of one valve when the other valve is open. 8he vessel 10 is suspended by rods 13 in a powder-in-vacuum insulation space 12 maintained by a motor-driven vacuum pump V. A second liquid outlet 35 forms with a vaporizer 36 located below the vessel 10 a duct 38, a solenoid valve 39 also controlled by the pressure switch 22, and a duct 24 a pressure build-up circuit whereby the operating pressure within the vessel 10 is maintained constant to effect delivery of liquefied gas to the vaporizer 27 and thence of gas to the outlet 34. The switch 22 opens the valve 39 when the pressure within the vessel 10 falls below the operating value to allow liquid to fall by gravity to the coil 36. At elevated vessel pressures gas flows from the vessel 10 through the duct 24, the solenoid valve 41, actuated by the pressure switch 23, which closes when the pressure within the vessel 10 exceeds a predetermined value, and the heater 32 to the outlet 34. As the switch 23 opens it the valve 41 closes the valve 29 and thereby prevents simultaneous withdrawal of gas and liquid from the vessel 10. A normally closed switch 44 in the outlet 34 permits the switch 23 to control valves 29, 41, and the switch 44 when open due to abnormally high outlet pdessure stops both gas and liquid flow from the vessel 10 by closing the valves 29, 41. Furthermore, thermal switch 45 closes the valves 29, 41 in the event of delivery temperature falling below a predetermined value. Warming liquid for the vaporizers 36, 27 and the heater 32 is circulated by a motor-driven pump 52 from and to a tank 50. The tank temperature is maintained constant by electric heaters 60 controlled by thermoswitches 70, 71, 72 and a switch 68 which, shpuld the liquid level in the tank fall too low, cuts off the heater current supply. The vessel 10 is recharged with liquid oxygen by forcing it through a filler connection 46, branches 47, 48 and the ducts 35, 24. The electric circuit for effecting the automatic control of the valves comprises a series of relays (see Group XXXV). Specification 405,843 is referred to.
