Title: Improvements in and relating to poultry houses, pigeon lofts and the like
IPC: A01K1/035
Filed: 1921-02-09
Abstract: 172,554. Bridges, A. Feb. 9, 1921. Fixed-chamber apparatus.-A poultry house, pigeon loft, or the like is fitted with a pivotally mounted perch by means of which the birds themselves close and lock the birds' entrance, lock the house door, measure off a predetermined quantity of food, unlock the house door and open the birds' entrance and deliver the measured quantity of food. The perch a<2> is carried by arms a mounted on fulcrums b which are adjusted on slides b<1> according to the number of birds so that when all are on the perch it is depressed. The arm a carries a link g which raises a flap f<1> into a horizontal position drawing down a slide f<2> pivoted to the flap until the food outlet f<10> is opened. A certain quantity of food then collects on the flap f<1>, the amount being regulated by adjustment of the wall f'. When the birds leave the perch the parts resume the position shown in Fig. 2, and the food on the flap f<1> is delivered on to a distributing board bearing ridges h by which it is scattered.

Title: Calibrating apparatus, particularly for an electrocardiograph
IPC: A61B5/0432
Filed: 1951-02-26
Abstract: 691,880. Electrocardiographs. CAMBRIDGE INSTRUMENT CO., Inc. Feb. 26, 1951 [Feb. 25, 1950], No. 4626/51. Class 81 (ii). Electrocardiograph calibrating apparatus comprises an amplifier indicator including a record medium and having means for advancing a record trace with respect to the record medium and indicating the magnitude of an input voltage as a function of time, a standard source of potential coupled by a first circuit to the input amplifier circuit with a first polarity, the first circuit being normally open at a vibratable reed for periodically connecting the standard source to the input circuit, whereby the actuation of manual means for initiating vibration of the reed produces a trace indicating the amplification of the amplifier and having time calibrating marks denoting the speed of the trace advancing means. The patient is connected across input terminals 4, 5 so that fluctuating patient' voltages pass through a two-stage push-pull amplifier 6 which is connected by sensitivitycontrol potentiometers 106, 108 with a vacuumtube bridge circuit 8. The amplified signal voltages produce unbalance in the bridge circuit 8 so that current passing through a galvanometer coil 192 causes deflection of a stylus 14 of recording apparatus 12. The stylus 14 moves over a chart paper 16 which is moved past the stylus 14 by an electrically driven roller 196. In order to calibrate the recording apparatus 12 with respect to time and voltage, a lever 20 of calibrating apparatus 18 is manually rotated to deflect a weighted reed 244 and thus set it in vibration and to enable the calibrator circuit to be made by closing contacts 254, 256. The reed 244 oscillates between two contacts 266, 274 so that calibrating voltages from a standard cell 262 are periodically reversed at the same frequency as oscillations of the reed 244 and have a substantially square wave form and are passed through the amplifier 6 and the bridge circuit 8 to be recorded on the chart paper 16. The stylus 14 may be in the form of a pen or may be heated to produce a visible trace on heat-sensitive paper.

Abstract: 1,219,816. Mixing fluids in flow. TORBJORN LOFGREN FORSAUNINGS AB. 31 Jan., 1968 [1 Feb., 1967; 19 May, 1967], No. 4973/68. Heading B1C. [Also in Divisions F2 and H3] Two fluids V and K (e.g. hot and cold waiter) flow into a mixing chamber B under the control of valves SV and SK controlled by a proportional mixing control ST. The valves are preferably solenoid valves and the control ST is a transistorized astable multivibrator, but hydraulic or pneumatic control may be used instead. The control ST applies pulses to the valves alternately; the pulses overlap in time and are of shorter duration than the reaction time of the valves, so that the valves do not completely close between pulses. The aggregate flow ratios are varied by variable resistors within the control ST ganged together to be varied in opposite senses, and by a thermistor TH1, or alternatively by a viscosity sensor. The mixed flow in conduit U may be directed to a further mixing chamber B' connected to a discharge conduit (e.g. to a shower head), and with a second inlet for the fluid K. Solenoid valves SK', SV' and a control ST' may then be used to alternate the two flows (e.g. to give a flow of 2 seconds warm water, 0.5 seconds cold). In another embodiment the function of the valves SK<SP>1</SP> and SV<SP>1</SP> are performed by the valves SK and SV.

Saline water is distilled by spraying it from nozzles in pipes 9 into hot combustion gases flowing through chamber 1 which contains parallel baffles 8 arranged in zig-zag formation extending at right angles to the direction of flow of the gases ; the water is instantly evaporated by contact with the hot gases, and the mixture of gases and vapour flows to condenser 13, from which the warm condensate, i.e. distilled water, is withdrawn through pipe 14. Water is also sprayed through nozzles 11 against baffles 8 so as to remove saline deposits. Saline residues are removed from chamber 1 through pipe 12. The hot combustion gases are produced in gas turbine plant 6, in which gas or oil is burned, and are supplied to chamber 1 through pipe 21. If desired, the fuel may be burned in burners 7 at the fore-end of chamber 1. The saline water to be treated is pumped through condenser 13, where it is preheated, before it is sprayed into the chamber 1. The mixture of hot gases and water vapour passes through wire-mesh filter 15 before it reaches the condenser 13. The warm condensate may. be passed to tank 23 which is maintained under reduced pressure by Venturi-tube 28, operated by the compressed effluent gases from chamber 1. Some of the condensate evaporates, and the remainder is chilled. The chilled condensate is withdrawn from the system through pipe 26. The turbine is used to drive the pumps and compressors.

Abstract: 682,841. Fluid-pressure servomotor-control mechanism ; fluid-actuated valves. YOXALL, L. S. (Foxboro Co.). March 2, 1951, No. 5169/51. Class 135. A fluid-operated motor 13, Fig. 2, 4, for moving a valve spindle 14 comprises relatively reciprocable members 27, 23 operable under the action of pressure applied in a chamber 26 between the members and opposed by an adjustable spring 37, and means whereby either member may be fixed while the other is attached to the spindle 14, so that the direction in which the spindle is moved by increasing the pressure in the chamber may be reversed. The valve stem is attached to a bar 50, and the valve body extends as a rigid yoke 20 having arms 21, and in the arrangement shown in Fig. 2, the arms are attached to the lower member 23 by bolts 24, and the bar 50 is attached to arms 47 which extend from a ring 31 fixed to the upper member 27. The spring acts between the member 27 and a seat 39 carried by a hollow spindle 33 projecting from the member 23 and thus as the pressure in chamber 26 increases, the stem 14 is moved upwardly to open the valve. By reversing the connection of arms 21 and bar 50 as shown in Fig. 4, the member 27 becomes fixed, and the member 23 movable and the spring now urges the member 23 upwardly so that increasing pressure in the chamber 26 moves the stem 14 downwardly to close the valve. The chamber 26 is sealed by a diaphragm 25 connected centrally to member 23 and peripherally to member 27 by the ring 31. Pressure fluid, e.g. air, is supplied to the chamber 26 by a pipe 12 from a controller sensing, e.g., temperature, pressure or flow. The pipe 12 is connected in Fig. 2 to a bore 44 communicating with the hollow spindle 33, and in Fig. 4 with a nipple 55 in member 27. In another arrangement, the motor comprises two plates connected by a flexible, corrugated, rubber cylinder, either plate being connectible to the stem, the one not so connected being supported by the arms 21.

Filed: 1940-03-21
Abstract: 535,503. Work gauges for grinding-machines. CHURCHILL MACHINE TOOL CO., Ltd., and ASHBRIDGE, H. H. March 21, 1940, No. 5318. [Class 60] A work gauge for precision grinding machines comprises two gauging contacts f, g which irrespective of the size of the work are arranged always to engage the work n at opposite ends of a vertical diameter, the contact f being mounted on a frame a carrying an electrical contact k and the contact g being mounted on a lever h pivoted to the frame at i and carrying the cooperating contact j. The lever h may operate a dial gauge p and the engagement of contacts j and k causes withdrawal of the wheel o when the work is reduced to size. The frame is pivoted at b to a link c which is pivoted to a base d. A screw m limits the movement of the link c. Another pivoted link q has a closed bifurcation which receives a pin t on the frame to ensure that when the frame is moved forward by the handle u the contacts f, g pass horizontally over the work piece. In operation, a piece of correct size is mounted and the frame pushed forward until link c engages stop m. The contact f is first adjusted to lift the pin r from the base of its slot and then contact g is adjusted to give the required distance between the gauge contacts when the contacts j, k are in engagement and the dial reads zero. Thus, when a subsequent work-piece reaches the required size the contacts j, k will engage and cause withdrawal of the wheel.
