Abstract: 931,624. Baggage-handling vehicles; endless conveyers. COCHRAN EQUIPMENT CO. Oct. 20, 1960 [Nov. 13, 1959], No. 35970/60. Classes 78 (1) and 78 (4). Endless conveyers.-A telescoping belt conveyer includes a single smooth working run 82 (Fig. 3), and three upper runs of which one, travelling in the same direction as the working run 82, is parallel to the working run, the arrangement being such that uniform tension of the belt can be maintained despite extension and retraction of the telescoping conveyer framework. In the form illustrated, the framework of the conveyer includes a pair of side members 71 (Fig. 6), formed with ribs 73 which are guided in pulleys 69 supported from the side frame members 60 forming the inner portion of the extensible conveyer 23. The inner and outer portions of the extensible conveyer carry longitudinal interdigitating tines 77, 54 (Figs. 4 and 5), supporting the upper run 82 of a belt. The belt is driven by a fixed roller 43 and passes over rollers 79, 80, 81 on the extending portion of the conveyer and over rollers 51, 51A, 48 on the inner framework of the conveyer. The rollers 48, 51A can be pressed against the belt by screws to adjust the tension. A fence 64 (Fig. 6) is hinged at the upper edges of the side members 60 of the inner frame so that it can be folded down to provide access to the conveyer from the sides. Further fences 88 telescope within the fences 64 and are connected to the forward portion 78 (Fig. 3), of the extending frame so that they are pulled out as the frame is extended by a doubleacting frame 87. A canopy 90 over the conveyer is supported by pillars 89 and arches 90 (Fig. 2), carried by the inner and outer frames of the conveyer so that the canopy is extended with the conveyer. The conveyer is swung about its heel pivot by a ram 58. Switches 94 controlling the conveyers are mounted on the outer portion 78 of the framework and are duplicated adjacent the inner end of the conveyer 23 and near the rear door 15. The belt 107 has a central ridge on its under side which engages grooves in its rollers. Resilient buffers 95, 96 on the extending framework include micro switches controlling the rams for pivoting and extending the conveyer 23. Loading and unloading.-The conveyer is employed in a vehicle for handling baggage, for example for loading and unloading aircraft, and is fed by a conveyer 22 (Fig. 3), extending along one wall of a compartment 10 in the vehicle. Adjustable luggage racks 19 (Fig. 2), are provided within the compartment, which is closed at the front by a curtain 16, and at the rear by a hinged door 15 provided with a latch 17.

Title: Improvements in or relating to electrical gas discharge tube circuits
IPC: H01J17/04
Filed: 1953-12-31
Abstract: 765,680. Gas discharge-tube circuits. GENERAL ELECTRIC CO.. Ltd., and BEESLEY, J. H. Dec. 16, 1954 [Dec. 31, 1953], No. 36375/53. Class 40(6) A gas-discharge tube of the type having a cathode, anode and trigger electrode has an asymmetrically conducting device connected in the input circuit to the trigger electrode so that the device presents a low impedance to current flowing towards the trigger electrode. The Figure shows the circuit of a cold-cathode gas-discharge tube in which rectifier 2 which may be a metal rectifier or germanium crystal is poled so that although a low impedance path is presented to a voltage applied to the striker terminal 11, reverse current flow from the striker electrode is prevented thus preventing damage to the tube or its re-striking. The value of resistor 4 is small in relation to the resistance in the non-conductive direction of element 2 so that when the main gap discharge of tube 1 is extinguished by lowering the voltage at terminal 10 the voltage of the striker electrode falls at a rate such that the tube cannot re-strike. The resistor 4 may be replaced by a further rectifier poled for low impedance to current flow between cathode and striker electrode. A very high input impedance to tube 1 may be obtained by shunting rectifier 2 with a high value resistor.

Abstract: 1,268,492. Sampling and testing. WOOL INDUSTRIES RESEARCH ASSOCIATION. 30 Oct., 1969 [31 July, 1968], No. 36514/68. Heading B1X. [Also in Division D1] Samples of scoured or partly scoured greasy proteinaceous material such as wool are periodically collected and transferred to a device which determines the grease content of a sample and controls the addition of scouring or washing agents to washing liquid in a treatment vessel in accordance with the determined grease content. Tufts of wool are pulled from a body (104), Fig. 2 (not shown), of such material which is moving on a conveyor between treatment vessels by a pair of forceps (106) mounted upon a cam-operated arm (105) and controlled by the engagement of a pressure foot (107) with the material. Individual tufts are blown along a tube (110) by compressed air admitted through a branch (112) and enter through a branch 11 into an inner tube 4 of the testing device shown where they are compacted by a perforated piston 7 which is reciprocated by an air motor AM1 controlled by switches S2, S4, S5 until a predetermined height of wool is accumulated in the tube. The tube 4 is heated by a jacket 5 which is supplied with water from a temperature controlled bath 9 which surrounds a supply 8 of washing or scouring solution. The latter enters the tube 4 at 22 by the action of a syringe 19, whereupon it is repeatedly circulated through the wool by the action of a further syringe 14. Upon completion of the circulation of washing solution, at least a part of the grease-containing solution is withdrawn at 23 by a syringe 15 to a turbidity cell and recorder 17 and the determination of the grease content made. The degreased sample and any remaining solution are emptied from the tube 4 by the opening of a door 18.

Title: Improvements in or relating to sawtooth wave-form generators using thermionic valves
IPC: H03K4/00
Filed: 1946-12-11
Abstract: 627,614. Saw-tooth generating circuits. SADIR-CARPENTIER. Dec. 11, 1946, Nos. 36645 and 36646. Convention dates, April 30, 1945, and April 2, 1946. [Class 40 (vi)] In a saw-tooth wave-form generator the flyback time is made very short by producing under the control of input pulses applied to a valve a sudden modification of voltage across the resistive element of a series resistorcapacitor network connected in the plate circuit of a second valve. Fig. 2 shows a sawtooth wave-form generator, current passing through resistor 4, diode 5 and valve 3, which is preferably a constant current pentode, valve 6 being normally cut-off and capacitor 1 charged to the voltage across resistor 4. When a positive pulse is applied to the grid of valve 6 the valve draws a heavy current, diode 5 is rendered non-conducting and the constant current of valve 3 flowing through network 1, 2 charges the capacitor 1 linearly with time. When the pulse at the grid of valve 6 terminates, the diode 5 is again rendered conducting the voltage across network 1, 2 falling almost to zero. The current flow through resistor 2 suddenly reverses and the steep fly-back of the saw-tooh wave-form is thus produced across the network 1, 2, Fig. 3 (not shown), the subsequent slow-discharge of capacitor 1 being removed from the output wave-form by a suitable limiting circuit. Fig. 4 shows a modification in which the network 1, 2 is in the cathode circuit of a constant current valve 3. Initially current passes -through valve 3 and the diode 5, valve 6 being cut-off. On occurrence of a positive pulse at the point 7 valve 6 is rendered conducting, a negative pulse appearing at the junction of capacitor 1 with resistor 2, diode 5 is cut-off and capacitor 1 charges linearly with time until the diode conducts when on the termination of the incoming pulse the capacitor rapidly discharges through diode 5. In the further modification shown in Fig. 5, valve 6 is initially cut-off and capacitor 1 is charged to the voltage across resistor 11. When a positive going pulse arrives at point 7 valve 6 conducts, its anode potential is reduced, diode 5 is cut-off and capacitor 1 discharges through resistors 2 and 11 until the diode is on the point of conducting again. Since capacitor 1 charges through resistor 11 the charging curve is exponential in shape and only the substantially linear portion is normally utilized.

IPC: G05B11/50
Filed: 1955-12-23
Abstract: 850,221. Fluid-pressure servomotor-control systems. CHELTENHAM AUTO CONTROLS Ltd. Dec. 24, 1956 [Dec. 23, 1955], No. 36872/55. Class 135. A pneumatic force-balance controller 10 comprises a sensing device 12 to which a gas pressure of the desired value is applied in direct opposition to the signal or measured value pressure so that deviation between the two pressures causes movement of an element 19, 19a to vary the gap 36 at the tip of a nozzle 32 which is fed with 'compressed air. The resulting variable nozzle pressure is transmitted via relay valve means 13 to a pneumatic regulator 49. The desired value pressure enters the controller 10 'through the port 30 and acts on the outside of bellows 15 to the inside of which the measured value pressure is applied via port 31. Attached to the bellows 15 is a rod 19 which upon movement of the bellows varies the gap 36 at the nozzle 32 which is supplied with air at constant pressure via a restriction 34 and bleeds to atmosphere via passage 28. The nozzle pressure is thus varied in accordance with the relationship between the desired value and measured value pressures and is applied to the outside of a bellows 39, 40 in a chamber 37. The inside of the bellows 39, 40 has an inlet valve 44 supplied from the constantpressure source and an outlet valve 47 exhausting to atmosphere via passage 48. Upon increase of nozzle pressure consequent on increase of the measured value pressure the bellows plate 40 is moved upwardly to open the inlet valve 44 so that the pressure in the bellows 39 builds up and upon decrease of nozzle pressure the exhaust valve 47 is opened to reduce the pressure in bellows 39 which is connected via pipes 46, 50 to the regulating unit 49. The lower end of the rod 19 is attached to a proportioning bellows 21, 22 in a chamber 51. The bellows 21, 22 is connected to the output from bellows 39. A variable proportion of this output pressure, obtained by a fixed restrictor 53 and a variable needle valve 54, is applied to the chamber 51. Integral action is obtained by a restrictor and capacity 59, 60, respectively, the pressure in the capacity 60 acting on a diaphragm 65 to vary the proportional pressure fed to the chamber 51. Sealing bellows 23, 24, 25 and 41 constitute exhaust channels.
