Title: Improvements in specific gravity indicators or recorders
IPC: G01N9/16
Filed: 1929-12-05
Abstract: 343,218. Specific-gravity estimating- apparatus. HODGSON, J. L., Biscot Road Works, Luton. Dec. 5, 1929, No. 37249. [Class 97 (iii).] Apparatus for indicating or recording the specificgravity of a fluid, and automatically providing compensation for errors due to changes of temperature comprises two displacers 1, 2 mounted on arms 3, 4 so as to form a balance beam pivoted on a knifeedge 5, the balance being contained in a chamber 10 through which is passed the fluid to be tested. The displacer 1 is hollow and is filled with a suitable fluid and the arm 3 is also hollow and dips at its inner end into a closed chamber 8 the centre of which lies on the axis of the knife edge. The chamber 8 is partially filled with fluid so that the end of the arm 3 is always sealed. A rise of temperature causes fluid to pass from the displacer 1 into the chamber 8, the consequent loss of weight of the displacer and contents being equal to the loss of buoyancy of the fluid in the chamber 10 due only to the rise of temperature. The beam is controlled by a pendulum weight 6 and by an adjusting, weight 7 which is so set that the weight 6 hangs vertically when the liquid in the chamber 10 has the mean specific gravity of the range to be indicated or recorded. The beam is connected to a pointer or a recording arm contained in a casing attached to the chamber 10. The chamber 8 may be wholly filled with liquid, its wall in this case having a flexible portion to accommodate changes of volume. When the liquid to be tested is under pressure the connection between the beam and the indicator &c. preferably consists of a magnet carried by the beam within the pressuretight chamber 10 and acting through a " window " of non-magnetic material on another magnet carried by the recording arm &c. In this arrangement the temperature compensation may be effected by forming the end walls of the displacer 1 as corrugated flexible plates.

Title: Improved ventilating and cooling system for railway carriages and other structures such as ships or buildings
IPC: F25D3/06

Abstract: 344,516. Ventilating railway carriages, ships, &c. STEWART, A. W., 150, Helen Street, Govan, Glasgow. Dec. 9, 1929, Nos. 37667/29 and 26658/30. [Class 137.] In a method of ventilating and cooling railway carriages and other structures, such as ships or buildings, air from outside or from a settling chamber is drawn through a filter 2 and forced bv a fan 1 through a tubular cooler 3 and a device 5 for removing condensed moisture, into an insulated duct serving the individual compartments. The tubular cooler is supplied with cold water from an ice tank 4 by thermo-siphon action. The temperature of the treated air may be automatically controlled by a thermostat 16 and diaphragm motor 15 which operates a valve 10 controlling a duct 9 arranged to by-pass the cooler. In a modification the motor 15 operates a valve 14 controlling the connection between the cooler and the tank 4. In the application of the invention to a coach of the corridor type a valve 13 is provided for admitting air into the fan casing from the interior of the coach, the corridor then serving as a return duct, or, alternatively a special return duct may be fitted to draw air from the compartments.

Filed: 1946-12-30
Abstract: 626,232. Automatic catches. THRUPP & MABERLY, Ltd., and WARDEN, W. F. Dec. 30, 1946, No. 38006. [Class 44] A door, lid, or like latch mechanism especially applicable to the boot of a car comprises a cupshaped member 1 forming the handle, the actuation of the catch member being effected by a plunger 7 having a stem part extending through an opening in the base of the cup-shaped member and a head part 6 which fits within the member 1 so as to close its open end and conceal the securing screws 4 or the like by means of which the member 1 is secured in position upon the door, lid, or the like. The end 12 of the plunger 7 has a transverse slot 13 accommodating the tongue part 14 of a trigger 15 the latter being pivotally mounted at 19 between a pair of bracket plates 17. The trigger 15 is formed with a depression 20 which engages with one end 21 of the catch member 9 which is pivoted at 16. The spring 8 acting against a pin 23 which being fixed to the catch member 9 rides in slots 24 formed in the bracket plates 17, presses the end 22 firmly against the fixed catch plate 10 and also presses the tongue 14 of the trigger member 15 against the plunger to force the latter outwards. A toe portion 26 engaging with the base wall 17a of the bracket 17 limits the turning movement of the trigger 15. The plunger may incorporate a barrel, forming part of a key-actuated lock mechanism to prevent depression of the plunger and consequent release of the catch when the mechanism is locked.

Title: Automatic electric control systems
IPC: G05B11/01
Filed: 1954-12-31
Abstract: 788,925. Automatic control systems for grinding mills. WESTON, D. Dec. 31, 1954 [April 5, 1954], No. 38116/56. Divided out of 788,924. Class 38 (4). In an automatic control system incorporating a monitoring device, a signal representative of a variable to be controlled is applied at a terminal 60 for comparison with a reference applied to a terminal 61, the resulting error signal being applied to the grid 63 of a double triode 64 whose anode output to the grids 70A of a dual-tube 70 is amplified for application to means connected between terminals 68, 75 for controlling the variable. A signal representing the quantity with respect to which monitoring is desired is applied to a terminal 77 for comparison with a monitor reference received at terminal 77A, the resulting error signal being applied to the grid 79 of tube 64 whereby to modify the output of the latter to amplifier tube 70A. The arrangement is such that if appreciable current flows in one half of tube 64, due to a large control signal error, the monitor signal is ineffective to vary the output of tube 64 and vice versa. Positive feedback for the amplifier tube 70 is provided by means of adjustable capacitance connected between terminals 87, 88. The circuit is described with reference to maintaining the sound level of a reduction mill at a value consistent with optimum grinding in the mill, the monitor preventing the load on the motor driving the mill exceeding a certain value. The output of the circuit is applied to saturable reactors controlling thyratrons regulating a magnetic pulsetype feeder for the mill.

Abstract: 1,022,534. Road traffic measurements. LABORATORY FOR ELECTRONICS Inc. Oct. 9, 1962 [Oct. 9, 1961], No. 38259/62. Heading G4Q. [Also in Divisions B7, H1 and H4] The passage of a road or rail vehicle is detected by mechanical displacement of part of an active semi-conductor device so that the conductivity of the device is altered. In one arrangement, Fig. 1 (not shown), a point contact transistor is mounted within a housing mounted under a road and may be hermetically sealed within the housing by a solid, liquid, or gas insulating medium. The transistor is biased either to conduct or not to conduct, and vibrations transmitted to the transistor cause it to reverse its conductivity state. A diode may be included in the circuit so that the output comprises pulses of only one polarity. In modifications, Figs. 2 and 3 (not shown), the transistor is of the junction type, and in a further modification, Fig. 5 (not shown), a piezo-electric crystal 56 is mounted above the base of a junction type transistor. In other arrangement, Fig. 4 (not shown), a road treadle 40 is connected to a point contact emitter electrode 42 such as a stiff tungsten or phosphor-bronze wire; movement of the treadle moves the point contact across the surface of the base of a transistor and thereby alters its conductivity. In a modification, Fig. 4 (not shown), the base of a transistor is provided with spaced conductive coatings, and vehicle actuation causes an emitter to rotate from contact with one conductive area 49<SP>1</SP> to contact with a second conductive area 49<SP>11</SP>
