Title: Air conditioning system
IPC: F24F3/10
Filed: 1957-06-24
Abstract: 826,072. Air conditioning systems. McFARLAN, A. I. June 24, 1957, No. 19800/57. Class 137 [Also in Group XIII] A building, having some rooms that may require to be heated and some that may require to be cooled, is air conditioned by providing each room with a conditioning unit comprising a heat exchanger over which a filtered mixture of fresh and recirculated air is drawn by a fan, the coils of the heat exchangers being connected to a fluid circuit consisting of a cold line to which cooled fluid is fed from a refrigeration system, a hot line to which hot fluid is fed from a heater utilizing the heat extracted by the refrgeration system and additional steam heating when necessary and a common return line. As shown, cold water is fed from refrigeration-stages 2, 4, 6, and 8 through the cold line 22 and hot water is fed from the condenser 19 attached to refrigeration stage 2 and steam heater 18 through the hot line 21 to the mixing valve 42 of conditioning unit 38 which is one of a number throughout the building, and from there to the coil of heat exchanger 40 over which filtered air is drawn by a fan 44 to be passed to the ducts 50 and 52. The water passes from the heat exchanger to a common return line 24 and a pump 25 from where it flows either through the condenser 19 via pipe 28 to the hot water line, or through the refrigeration system via pipe 29. When the heat extracted from the spaces being cooled is greater than that required to heat the other spaces, the excess heat is dissipated by a pump 62 circulating cold water through pipes 66, 70 from a cooling tower 68 to the condensers 11, 13, 15 and 17 of the refrigeration system. The air conditioning system is controlled automatically by the thermometer 77 which operates the controller 56 of the mixing valve 42, the controller 80 and thermometer 81 which control the refrigeration units to maintain a constant cold water temperature in line 22, and the controller 82, thermometer 85 and external themometer 83 by which the hot water temperature is maintained inversely proportional to the outside temperature. The automatic controls may be overriden by the manual control 86 to provide rapid heating or cooling of the building.

Filed: 1939-07-07
Abstract: 534,649. Photo-electric apparatus. PHOTOSWITCH, Inc. July 7, 1939, No. 19828. Convention date, May 2. [Class 40 (iii)] A gasoline filling station is provided with photo-electric devices so arranged that the presence of a vehicle 105 in a dispensing area causes reflection of light on to a photo-electric cell, whereby a signal is given. As shown, a lamp unit 71 and a photo-cell unit 70 are arranged side by side on the platform of a gasoline pump, so that a vehicle 105 within the correct distance reflects light from the lamp to the cell, and an amplifier connected to the cell thereby operates the relay M of a sounding device, the circuit being as described in Specification 514,528. The sounding device may produce two sounds of different pitch when the vehicle enters and leaves the area respectively. The sounding device may be situated at any convenient place, or may be mounted close to the lamp and cell units. The Specification as open to inspection under Sect. 91 describes also arrangements in which signals are given by the obturation of the light beam from the source to the cell by a vehicle mirrors being provided to reflect the beam across various areas where it is desired the vehicle should produce a signal. This subject-matter does not appear in the Specification as accepted.

A solution containing approximately 12% by weight iron and 3% by weight HCl is continuously withdrawn, filtered and fed to a vacuum crystallizer, where it is indirectly heated to 70‹ C. The hot solution is sprayed into the crystallizer, which is maintained at 50 mm. of mercury absolute, where water and HCl evaporate, cooling the liquid to 55‹ C. when ferrous chloride crystals separate. The liquid is recirculated to the heater along with fresh solution, while the crystals are centrifuged, and sprayed with 5% of their weight of water. About 93% of the iron is recovered, the remainder being removed in a bleed stream which eliminates impurites such as nickel chloride.

Title: Coupling for hoses or pipes
IPC: F16L37/23
Filed: 1953-07-21
Abstract: 731,578. Pipe couplings. TECNO-TRADE ANSTALT. July 21, 1953 [Aug. 4, 1952; Jan. 17, 1953], No. 20275/53. Class 99 (1). A pin 58 projecting from a shut-off device 45 in a coupling section 41 enters a shut-off device 60 in a second coupling section 43 so as to displace a cylinder 75 locking the device 60 in position, whereupon the devices 45, 60 move as one and communication is established between pipes 42, 44, connected, e.g., to the hydraulic brakes of a trailer and the hydraulic cylinder of a motor vehicle respectively. The locking- device comprises balls 74 engaging a recess 72 in the section 43 and recesses in the member 60. When the cylinder 75 is displaced against the action of a spring 76, the balls snap out of the recess 72 and into a groove 59 in the pin 58 so as to couple the members 45, 60 together whereupon they are pulled downwardly by a tension spring 67 or a compression spring. On breaking the coupling, the cylinder 75 moves the balls back into the recess 74 when the pin 58 has returned the member 60 to normal position. The device 45 has a longitudinal bore 48 opening into a transverse bore 49 communicating with a space 50 formed by a cylinder 51 moved inwardly against the action of a spring 56 when the coupling is made ; a similar space 63 surrounds the device 60. The spaces may be of such small diameters as to  leave only clearance space for the devices 45, 60, the gaskets 54, 55 and 61, 62 shown being replaced by sealing rings. The coupling sections may be surrounded by a jacket filled with brake fluid.

Title: Improvements in or relating to electron tubes
IPC: H01J17/04
Filed: 1930-07-04
Abstract: 358,550. Converting. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Cutler - Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) July 4, 1930, No. 20314. [Class 38 (ii).] In a method of controlling the discharge of a gas-filled electron discharge tube, a control grid 23 formed by a conducting ring, associated with the anode 22 is supplied with a potential with respect to the cathode 21, such, that a glow discharge is initiated between anode and grid, thus reducing the starting potential required for the main discharge between the anode and cathode, and the grid potential may be varied to control the instantaneous discharge starting potential. A small negative potential on the grid prevents the occurrence of the main discharge, but if the potential be raised negatively till a glow discharge occurs between anode and grid, the main are discharge is started even at a lower voltage between anode and cathode than is normally necessary. In Fig. 2 showing an alternating potential applied to the anode, with zero grid potential a voltage A B is necessary between anode and cathode to initiate the discharge and the curve of current through the tube is A H C. If the grid potential is made E<1> negative to the cathode the arc starts at a voltage D F between anode and cathode such that the total voltage D F plus E<1> between anode and grid, is equal to the glow potential. In a modification, Fig. 8, alternating current is applied to the anode by a generator 26 which also drives a synchronous motor 28 having a commutator 29 and brushes 31, 32 for applying the high negative voltage of a battery 35 periodically to the grid which is normally biased negatively by a battery 34 so that the arc does not strike. A translation device 27 utilizes the rectified current. The instant in the cycle at which the high negative potential is applied to the grid is controlled by rotating one of the brushes 32. The grid, which is normally biased to prevent the arc striking, may be supplied with pulsating current through a half wave rectifier from a phase shifting transformer energized from a three phase system, and the discharge tube may be connected between two of the three phase lines. Control of the current flowing through the tube is obtained by altering the phase of the grid potential relative to that of the anode potential.

Two or more winding groups may be used to give greater current carrying capacity or alternatively the conducting sheet may be replaced by a number of coplanar or coaxial sheet conductors wound as a single group.
