Abstract: 429,831. Kinematograph projectors. SPILLER, R. F., Parc Gwyllt Cottages, Coity, near Bridgend, Glamorgan. Nov. 7, 1933, No. 30856. [Class 97 (i)] Means for automatically operating visual signals for facilitating change-over comprises a photo-electric cell co-operating with marginal markings on the film to operate a selector switch which in turn controls three signal lamps ; means for effecting the operations of which the lamps give warning may also be automatically operated. The film markings may consist of three black sections arranged at various distances from the film ends on a clear margin or clear sections on a darkened margin, and pass across a slightly narrower slot in the film trap G of a magazine S, so as to control the beam from a lamp L to a photoelectric cell I. The cell currents are amplified and transmitted to a solenoid E to operate an armature J and turn a toothed wheel N one tooth at each impulse. The wheel N carries a spring contact M engaging one of a number of studs in each position of the wheel. During normal running the contact M engages one of the studs O, but the impulses caused by the markings near the film end bring it successively into engagement with one of the contacts A, B, C, thereby operating relays to complete successively the circuits of three signal lamps. The lamps may be coloured and marked " stand by," " start motor " and " change over." After change over, the contact M is moved to the next stud O by hand turning of a thumb screw K<2>.

Filed: 1975-07-24
Abstract: 1472240 Railway vehicle undercarriages SCHWEIZERISCHE LOKOMOTIV UND MASCHINENFABRIK 24 July 1975 [25 July 1974] 31002/75 Heading B7L A rail vehicle having two bogies 2, 4 pivotally supporting a body 1 for rotation about respective vertical axes 5, 7 includes two pairs of fluid-pressure-operated actuators 17, 18 and 19, 20, each pair being connected to a respective bogie 2 or 4 to exert forces thereon to rotate the bogie about its vertical pivot axis, the two actuators of each pair being mounted on opposite sides of the longitudinal vertical median plane of the vehicle and being inclined downwards towards that plane with the lines of action of their forces intersecting that plane on the same side (i.e. both fore or aft) of the vertical pivot axis of the associated bogie, and the four actuators 17 to 20 being interconnected so that rotation of either bogie 2 or 4 about its axis 5 or 7 tends to cause an opposite rotation of the other bogie. As shown, the actuators of each pair are connected between brackets 21 of an intermediate third bogie 3 and brackets 24 on a member 13 which is pivoted to the associated bogie 2 or 4 at 14, the weight of each member 13 being carried by members 15, 16 attached to the third bogie 3. The actuators 17 to 20 are doubleacting actuators whose chambers are suitably interconnected with those of the other pair by fluid pressure lines 25 and 26. Additional connection is provided by further actuators 31, 32 fed by the lines 25 and 26 and linked via a spring element 41. In another form, Figs. 4 and 5 (not shown), the pairs of actuators 17, 18 and 19, 20 are not interconnected by fluid pressure lines but communicate only via modified further actuators (51, 52) and a spring element (50). The actuators 17-20 need not extend 'at right angles to the longitudinal vertical median plane of the vehicle and may be inclined thereto such that the lines of action of the forces of all four actuators intersect midway between the two bogies 2 and 4 at railtop level. Such intersection occurs in an embodiment, Figs. 6-8 (not shown), in which there is no intermediate bogie and the actuators 17-20 and members 13 are carried by the underside of the vehicle body.

Title: Improvements in and relating to heating and cooling installations
Inventor: TAYLOR FRANK MARTIN HUSSEY
IPC: F24F3/10
Filed: 1957-10-03
Abstract: 906,147. Systems for heating or cooling buildings. THERMOCONTROL INSTALLATIONS CO. Ltd. Jan. 2, 1959 [Oct. 3, 1957], No. 31011/57. Class 64 (2). [Also in Group XXIX] A fluid control valve for use in heating and cooling installations for buildings in which either hot or cold fluid is passed through a coil or radiator to either heat the coil or extract heat from the surroundings according to whether heating or cooling is required, comprises a valve V having an element E movable through a rack and pinion K, P by a reversible motor M, electric, pneumatic or hydraulic, responsive to changes in temperature detected by a thermally-responsive unit or temperature controller located either inside or outside the building. When, e.g. the ambient temperature is low, the motor M moves the element E to a position in which a flow passage 3 to the inflow side of a coil X is closed from a flow passage 2 connected to a pipe CF through which cold fluid flows and fully open to a flow passage 1 connected to a pipe HF through which hot fluid flows. As the ambient temperature rises the temperature controlled motor moves the element E upwardly to progressively reduce the flow of heating fluid to the coil until when the desired ambient temperature is reached, both the passages 1 and 2 are closed. Should the ambient temperature continue to rise the element E will continue to move upwardly to progressively open the passage 2 to supply cooling fluid to the coil without the reversal of the motor having taken place until the ambient temperature reduces to its desired value. Conversely if the ambient temperature is high, the motor will operate in the reverse direction to initially progressively close passage 2, then close both passages 1 and 2 and if necessary progressively open passage 1. A second valve 2V is also operable with the valve V to simultaneously control the supply of cooling medium to a coil X1 located in a part of the building where heat is produced, e.g. by machinery. As the element E moves downwardly to increase the supply of heating fluid to the coil X, the element E2 moves downwardly to reduce the supply of cooling fluid from a pipe F1 to the coil X1. In a modification, the flow passages 1 and 2 are connected to the same supply pipe and this single pipe may be supplied either with hot fluid or cold fluid. The changeover being accomplished either manually or automatically by means of a temperature detector which causes hot fluid to flow when the ambient temperature is below a predetermined value and cold fluid to flow when ambient temperature is above this value.

Abstract: 832,607. Cold separation of gas mixtures. AIR PRODUCTS Inc. Oct. 30, 1954, No. 31418/54. Class 8(2). A process for the cold separation of a gas mixture, e.g., compressed air comprises feeding liquid air or a component-rich liquid as reflux into a first column 51, withdrawing liquid from the base of said column 51 and elevating it to the head of a second column 50 solely by the addition of heat derived from the separation cycle and using it directly as reflux or indirectly, e.g. by passing it through a coil 63. Crude liquid oxygen from a pool 70 is carried up ducts 80, 81, 82 to a duct 86 by partial vaporization effected by relatively warm high pressure nitrogen from the head of column 50 flowing through ducts 90, 91, 92 and down heat interchangers 87, 88, 89. The so-cooled nitrogen is expanded at a valve 94 and passes to the column 51 as reflux, and the oxygen vapour produced during the lifting operation traverses ducts 96, 97, 98 and is joined by oxygen vapour from the coil 63 before being returned to the column 51. In a modification reflux for the first column comprises liquid nitrogen from a trough at the head of a lower section of a twopart second column, and crude liquid nitrogen is lifted from the base of the first column to the head of the upper section of the second column by heat interchange with crude liquid oxygen from the base of said lower section. In a further modification wherein both columns operate at the same pressure reflux for the first column comprises incoming air liquefied in a coil at the base of the second column and liquid oxygen is lifted from the base of the first column by heat interchange with cold air feed. Specification 832,616 is referred to.
