IPC: F16K27/02
Filed: 1955-12-09
Abstract: 792,455. Valves. ROBERTSHAW-FULTON CONTROLS CO. Dec. 9, 1955 [April. 7, 1955], No. 35436/55. Class 135. A hot and cold water mixing valve comprises a valve unit 10, Fig. 1, detachably secured by a single bolt 20 to a manifold fitting 12 having cold and hot water inlets 14, 15 respectively and a pair of outlets 16, one of which may be plugged if not required. Each inlet is fitted with a non-return check valve 42, Fig. 4, which may be positively held on its seat by a screwthreaded plug 34 to prevent leakage from the manifold when the valve unit is disconnected to facilitate repairs to the valve unit. Parallel bosses 55a, 57a on the manifold fitting sealingly connected to complementary bosses 55, 57 on the valve unit connect the inlets 14, 15 through passages 60, 62 to a pressure equalizing chamber 66 in which is slidably mounted in end caps 68, 72, Fig. 6, piston valves 80, 82 connected by rods 84, 88 to a piston 92 subjected on opposite faces to the pressure of cold and hot water so that the pressures of the cold and hot water leaving the chamber and entering a mixing chamber 160, Fig. 2, through ports 102, 104 are the same. The mixing chamber houses a sleeve valve 116 connected to a bellows type thermostat 122 filled with an expansible liquid whereby an increase in pressure causes the bellows to expand against a spring 134 to control the ports 102, 104 and thus the temperature of the mixed water. The bellows is connected to a bush 140 slidable in a casing part 144 and coacts through a ball 138 with a face-cam 154 secured to a stem 148 to adjust the temperature of the mixed water which passes to the outlet (or outlets).

Title: Improvements in cameras for producing multiple photographs
IPC: G03B19/02
Filed: 1934-12-10
Abstract: 438,298. Photographic cameras. HANSEN, J. P., 52, Norrebrogade, Copenhagen. Dec. 10, 1934, No. 35447. [Class 98 (i)] In cameras for taking multiple photographs wherein two frames are provided which move in steps in two directions at right angles, one or more ground glasses are provided on one or both of the frames and the means for controlling the displacement of the frames can be changed between the exposures to produce different displacements. In order to vary the picture size in accordance with the selected displacement, the camera is provided with exchangeable masks. These masks may be carried by a rotatable disc, a sliding bar, or a flexible band stretched between two reels. Alternatively, a bar with a single aperture provided with edge guides for receiving different masks may be used, or a metal bushing may be provided on the apparatus to which caps having mask apertures may be applied. In the form shown the apparatus comprises a base plate 1, a frame 14 mounted to slide horizontally on the base plate, a frame 16 sliding vertically on the frame 14, and a plate holder 17 mounted in the frame 16. A ground glass focusing screen 45 is attached to the frame 14. The horizontal movements of the frame 14 are controlled by a toothed wheel 25 engaging a rack 24 provided on its upper surface with notches 34 into which a spring lug 33 enters. The rack is carried by the frame 14 and may be exchanged for another having a different number of notches. The vertical displacements may be produced by a plate 43 on the base 1 having recesses or rails 43<a> engaged by a follower 42 on the frame 16. Alternatively the vertical movements may be controlled by an interchangeable ratchet bar 40, Fig. 3, carried by the frame 14 and engaged by a spring pressed pawl 37 on the frame 16. The shutter may be interconnected with the apparatus so that it is opened automatically when the ground glass screens are moved into position in front of the lens. The shutter may also be arranged to operate after each movement of the plate. It is stated that the apparatus may be used for enlargements by replacing the plate holder by a negative and providing a source of light behind the apparatus.

Title: Blade connection for mowers
IPC: A01D34/535
Filed: 1960-10-17
Abstract: 895,159. Forage harvesters. MOTT CORPORATION. Oct. 17, 1960 [April 20, 1960], No. 35457/60. Class 6(3). In a mower of the type comprising a driven, rotary, horizontal shaft carrying flail-type cutter blades which swing outwardly under the action of centrifugal forces as the shaft rotates, the blades are mounted in pairs on lugs extending radially outwards from the shaft. Each pair of blades is connected to the corresponding lug or lugs by a split link, the free ends of the link engaging with attachment members secured to the free ends of the lug or lugs. As shown in Fig. 2, the blades 26 of the mower are connected to pairs of lugs 31 welded to the cutter shaft 11, by means of U-shaped links 34, each engaging in slots 46 in a pair of blades, the free ends of each link being located in channelled attachment members 33 bolted in place between a pair of lugs 31. The ends of the links are thereby securely located between the webs 37 of the attachment members, the end flanges 42 thereof, and the outer ends of the lugs 31. In one modification of this arrangement, the end flanges 42 of the members 33 are deformed slightly to accommodate a link 34 of split, circular shape. The side flanges 38 of the attachment members prevent rotation of the members relative to the lugs, and in an alternative arrangement, where the flanges 38 are omitted, such rotation is prevented by extending the members 33 to abut against the shaft 11, the abutment edges of the members being curved to conform to the shape of the shaft 11. Alternatively, and as shown in Fig. 5 the attachment members comprise plates 52, 53, each formed with holes to receive the ends of a link 34 and interspaced with pairs of lugs 31, 31<SP>1</SP>. The lug 31 of each pair is shorter than the lug 31<SP>1</SP>, the latter being sufficiently long to extend between the ends of the corresponding link 34. Alternatively, the shorter lug may be dispensed with, in which case the attachment members are bolted one on each side of the longer lug 31<SP>1</SP>.

[Class 37.] Relates to an instrument responsive to the relative magnitudes of alternating currents or voltages and of the type comprising a field coil and a pair of differential armature coils co-operating therewith, the armature coils being connected in parallel circuits and the field coil in series therewith. One of the circuits 28 to be compared is connected to the pair of parallel coils and in series with the field coil, the other circuit 29 being connected across the pair of parallel coils in series. A pair of stationary field coils 11 co-operates with movable armature coils 12, 13 attached to the spindle 15, the armature coils being either placed at right-angles to each other, or they are co-planar, in which case vanes 18 are mounted on the spindle. Resistances 19, 20 are connected in series with the coils 12, 13, the common terminals 21, 23 being connected to one source with the field coil 11 in series. Torsionless hair springs 25-27 make current connections to the field and armature coils. A current-limiting resistance 30 is provided in the connection to the other source 29 The values of resistances 19, 20, 30 are'selected so that the currents 11, 12, 13 are in phase with the respective voltages. When the voltage of source 29 is zero or 90‹ out of phase with respect to the voltage of source 28, the resultant flux due to currents I, I2 is in the same direction as the flux due to the field coil and an instrument zero position is defined. When the voltage 29 has an in-phase component the flux due to either 11 or 12 is weakened and the pointer is deflected in a direction depending on the magnitude and polarity of the in-phase component. By using one source as an exciting circuit of constant current or voltage, the magnitude and polarity of similar components of the other source may be indicated, while if the voltages or currents of the sources 28, 29 are constant, phase angles are indicated.
