Title: Improvements relating to ventilating arrangements for vehicles
IPC: B61D27/00
Filed: 1948-02-05
Abstract: 637,699. Ventilating vehicles. CHILTON. A. H., and STONE & CO., Ltd., J. Feb. 5, 1948, No. 3401. [Class 137] [Also in Group XXXV]  A heating and ventilating apparatus for a vehicle especially a railway coach, is such that the proportions of fresh air drawn through intake 14 and return air through intake 9 are varied by thermostatically controlled adjustments of the pivoted damper 12. The position of the damper when 100 per cent fresh air or 100 per cent return air is being circulated and the train is stationary, is determined by the limit switches 341, 343. Fresh air is drawn in by fan 3 over heater 2, supported by a frame-work 1 in a housing 4, the air being distributed by duct 11 to various compartments and returned through the intake 9. Alternative damper devices may comprise a single flap or two flaps coupled by a link. The damper 12, air and floor heaters 2, 18 are controlled by thermostats 47, 48, 49 through cooling, air-heat and floor-heat relay windings 31-33, these being energized by an axle driven generator 16 through on-contacts 17 of a cut-in switch while the vehicle is in motion, and by batteries 25 while stationary. At or above 75‹ F, when the vehicle is at rest, the thermostat 47, which may be provided with a heater 50 giving a 3‹ F bias, completes the circuit of the cooling relay winding 31, thus closing the contacts 29 to energize the field windings 26 of the motor 28, causing clockwise rotation of the damper. In this temperature range, the windings 32, 33 of air heat, floor heat relays will be short circuited by thermostats 48, 49 respectively. Below 70‹ F, the windings 32 are no longer short circuited and become energized, closing contacts 30 to excite motor field windings 27 and cause anti-clockwise rotation of the damper. The solenoid 36 is energized through contacts 37 of the cut-in switch when the switch is open, and renders the limit switch 342, which is adjustable relative to the switches 34<SP>1</SP>, 34<SP>3</SP>, ineffective when vehicle is stationary. When the vehicle is in motion and contacts 17 closed, heaters 2, 18 are switched on by respective relays when temperature is below 68‹ F. The damper being closed, temperature will rise and the heaters will be switched off at 68‹ F, 70‹ F respectively. If temperature rises above 75‹ F the damper will be turned in clockwise direction, coming to rest when temperature falls below 75‹ F. If temperature falls below 70‹ F, heater 2 is switched on and the damper turned in anticlockwise direction towards switch 342, the winding 36 being open circuited at the contacts 37. The damper will thus oscillate between limit switches 34<SP>2</SP>, 34<SP>1</SP>. The fan 3 is driven by motor 40. Air disturbing fans 42 will be switched on only when the cooling relay is in action and the contacts 46 are closed.

Abstract: 824,977. Photographic printing apparatus. ILFORD Ltd. Jan. 20, 1958 [Jan. 31, 1957], No. 3438/57. Classes 98(1) and 98(2) [Also in Group XXXV] For colour printing or use with variable contrast black and white material, the apparatus has a source of light changing between maximum and minimum brightnesses at a high cycle frequency filtered by passage through an element made up of uncoloured and coloured areas which is introduced intermittently at a frequency related to the cycle frequency of the source by an integral factor and means for adjusting the relative phase relationship between the source and the filter element. The source may be a gaseous discharge lamp, and the filter element one with coloured areas as of yellow magenta or cyan and also uncoloured areas for reciprocating passage or operation as a rotating disc. As shown there are two such discs 8, 9 with coloured sectors 10, 11 and 12, 13 driven motors 14, 15 respectively in the path of light from discharge lamp assembly 1, 2, 3 through condenser lenses 4 transparency 5 and objective lens 6 to print material 7, the same alternating current supplying both motors and lamp, and adjustment of phase relationship of each filter disc can be effected by rotation of the housing of the motor which drives it. The colour of sectors 10, 11 differs from that of 12, 13. Maintenance of the ratio of blue green and red light at a predetermined value by using monitoring photocells each controlling one colour and arranged to control via servomotors the angular position of the rotating discs is indicated.

Title: Improvements in and relating to pneumatically operated electric switches
IPC: H01H33/32
Filed: 1934-02-02
Abstract: 412,882. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Feb. 2, 1934, No. 3506. Convention date, Feb. 2, 1933. [Class 38 (v).] In an arrangement for pneumatically operating two or more electric switches sequentially the initiation of the pneumatic operation causes one of the switches to be operated immediately and the remaining switch or switches to be pneumatically operated with a time-delay action which is independent of the operation of the immediately-operated switch. As shown in the Figure a cylinder 16 containing compressed air constantly maintained at operating pressure is connected to the switch-operating mechanism through a control valve and when this is opened the piston in the cylinder 7 is raised immediately to close the switch 4 in the line 1. The air passes to the other switches, however, through a throttling device 20 and an intermediate cylinder 21 and the switches 5, 6 in the remaining phase conductors 2, 3 are operated only after the pressure in the intermediate cylinder 21 has risen to a value sufficient to raise the pistons in the cylinders 8, 9. These cylinders may be directly connected to the cylinder 21 as in the latter case or may be connected through a valve 22 which is automatically opened when the pressure in the cylinder 21 reaches the predetermined value. The time delay in the operation of the switches 5, 6 may be varied by adjustment of the throttling device 20. The apparatus may be employed to operate isolating switches in succession or in polyphase plants may be used to operate a switch of relatively high rupturing capacity in one phase at a different time to the operation of switches in the remaining phases so that the stronger switch is subjected to the maximum stress.

Abstract: 1,145,596. Marine vessels; stabilizing; hull lubricating. A. J. TUCKER. 24 Jan., 1967 [27 Jan., 1966], No. 3618/67. Headings B7A, B7MandB7S. [Also in Division E1] In a marine vessel that is capable of being stationed in open sea, the hull 11, Fig. 2, has inwardly-inclined sides 13 and a plurality of mutually-perpendicular plates 20 attached to the bottom thereof at right-angles thereto so as to form rectangular downwardly-facing pockets, whereby the effect of wave-action upon the vessel is rendered minimal. A deck 18 is supported by cylindrical tanks 15 that contain tubes 16, which extend to the bottom of the hull and constitute wells through which work operations can be performed with the aid of winches 17. A propeller 21 and a rudder 22 are provided at the stern; and ballasting means (not shown in Fig. 2) are lodged in the hull so that the draft of the vessel can be increased when the vessel is put on station. The bottom of the hull may include a plurality of steps carrying mutually-perpendicular plates 35, 36, 38, Fig. 3, which form the pockets aforesaid. When the vessel is under way, drag is reduced by purging the said pockets of water with a compressed gas e.g. air or exhaust gases from a gas turbine (not shown), the pressure of which gas may be rendered sufficient to separate the hull from the water of flotation. The gas enters the pockets from a tank 41 through nozzles 43, slots 37 being provided in intermediate plates to effect communication between adjacent pockets. As shown in Fig. 3, the hull may contain a tank 30 extending to the bottom thereof, which tank is similar to each of the tanks 15 and contains a tube 31 that has a purpose similar to that of the tubes 16. The ballasting means may comprise a tank 52, Fig. 6, which can be purged of water (to reduce the draft of the vessel) by compressed air that is stored in a tank 54, a vertical open-ended pipe 57 being charged with water of flotation and serving as a safety valve for the tank 54. Water is ejected from the tank 52 through a pressure-sensitive valve 53. Air for purging the pockets aforesaid of water is delivered thereto through a conduit 58 connected to a tank 51 that is charged with air from the tank 54. The bottom of the hull may have a curvi-form profile, Fig. 4 (not shown), such that a submarine vessel (81) can be cradled thereby while it is held adjacent the hull by lifting tackle (80). Alternatively, the bottom of the hull may be. flat. Fig. 5 (not shown), and the sides and top of the hull may have a plurality of mutually-perpendicular plates 95, 96 attached to the external surfaces thereof to impede the flow of water thereover due to wave-action, slots (97) being provided in said plates to facilitate drainage. It is stated that the vessel may be used for effecting marine salvage, marine construction, pipe-line installation, mother-ship service for submarines, life-support for underwater residences and stations, and maintenance of subaqueous petroleum and gas wells.

Abstract: 1449701 Printers SIEMENS AG 28 Jan 1974 3863/74 Heading G4H [27 Feb 1963] in Division [Also H2] A linear motor (see Division H2) comprising a coil 4 moving in the magnetic field between two parallel ferromagnetic bars 1, is used to position the head of an ink-jet printer. For precise positioning, a differential receptor optoelectric transducer 15 provides signals representing the positions of the receptor axes 15a, 15b. The difference therebetween 16 is normally fed via amplifier 12 to provide current in the coil 4 stabilising the transducer opposite a tooth peak 23. To move the head, a switch 20, 21 is moved up or down (for left or right movement). An impulse from generator 25 thus displaces the head slightly. Since the amplifier 16 output now comes via inverter 22 to the amplifier 12, the force generated by the coil 4 continues the movement instead of opposing it. To avoid stabilising on the adjacent trough 24, a reset pulse 26 returns the switch 20, 21 to its normal position after a suitable delay. In a drive current control circuit (Fig. 6 not shown), a divider chain comprising transistors and resistors is provided between positive and negative supplies. Enabling one or other transistor provides a positive or negative reference, which is compared to the output of a pick-up coil mounted adjacent the drive coil.
