Filed: 1959-10-08
Abstract: 970,341. Hydraulic brakes. GIRLING Ltd. Jan. 9, 1961 [Oct. 8, 1959], No. 34090/59. Heading F2F. A pressure-limiting valve has a spring-loaded valve member 13 movable into engagement with a seating 15 in a direction opposed to the liquid flow, the effective area of the valve being greater than that of the seating such that when closed the valve is subject to a positive closing pressure. Liquid pressure from a master cylinder is applied to a pipe 10 which leads to the front wheel brakes by pipe 11 and to a chamber 12 of the pressure limiting valve. The liquid flows through the seating 15 to a chamber 16 in communication by pipes 18 with the rear brakes. When a predetermined pressure is reached, the pressure acting on the enlarged valve head 17 remote from the seating overcomes the opposing forces of a spring 19, normally holding the valve open, and the pressure on the seating area and the valve closes. On release of the pressure the spring 19 opens the valve and immediate opening is ensured by a spring-loaded by-pass valve 22 connected between the chambers 16 and 12. A practical embodiment of the valve is shown and described.

Abstract: 867,807. Fluid flow detectors. GLOSTER AIRCRAFT CO. Ltd. Oct. 30, 1958 [Nov. 1, 1957], No. 34167/57. Class 69 (1). [Also in Group XXXIII] A fluid flow detector comprises a flat plate 1 adapted to be supported in and acted upon by the fluid the flow of which is to be detected, rods 2 extending from the plate 1 through apertures in a receptacle 4 and being fulcrumed therein by resilient material in the form of sealing rings 9 arranged between the rods 2 and the receptacle means being provided for indicating the degree of flow of the fluid in accordance with the angular position of the member 1. The rods 2 are connected by a cross-bar 5. The longitudinal axes of the rods 2 intersect the plane of the plate 1. The apertures in the receptacle are provided with bushes 3 of hardened material, the clearance between the rods 2 and the bushes being sufficient to allow the plate-rod assembly to rock freely between the limits set by the cross-bar 5 abutting stops 10, 11 which are an integral part of the member 4. A pressure-sensitive electric device in the form of a microswitch 12 is secured in the member 4. The switch is so arranged that its operating plunger just touches the cross-bar 5 when the plate-rod assembly is in its mid position. When the device is installed on an aircraft air flow acting in the direction of the arrow A (Fig. 2) will cause the plate-rod assembly to tilt and so to actuate the switch to hold off a stall warning indicator. If the velocity of the air flow acting in the direction of arrow A falls below a certain predetermined value a spring in the switch 12 will actuate the switch to operate the stall warning indicator and will also push the cross-bar 5 back to its normal position. To prevent excessive loading of the switch due to a high velocity of air flow in the direction of the arrow A an over-ride mechanism consisting of a spring- biased plunger 13 is provided (Fig. 3).

Filed: 1973-07-18
Abstract: 1442683 Shearing H ZAHLAUS 18 July 1973 [18 July 1972 15 June 1973] 34287/73 Heading B3W Metal rods to be cut to length one or two at a time are moved into a shearing machine laterally of their axes on a carriage to be aligned, fed, singly or in pairs, against a gauging stop, adjustable in the feed direction, and cut by a vertically reciprocable knife, the knife on completion of a cut being pivotable by the advancing rod(s), as they advance over the cut rod(s), the length settings, counting and sorting of the cut rod(s), according to length, and batchwise removal of the cut rod(s) being controlled by a preselected programme. A carriage 17 is moved in the direction of the arrow, Fig. 3, i.e. out of the machine, manually or mechanically to cause one or two rods 16, laid on surface 19 while the carriage was pushed into the machine, to drop on to a rail 21 and a cone 15 to disengage a switch 13 and thus actuate a fluid cylinder 32 to move a roller 30 away from the roller 18. Moving the carriage back in pushes the rod(s) from the rail in to the groove of roller 18 and causes the roller 30 be be pressed on to the rod(s). A further fluid-actuated roller 40 presses the rod(s) against a roller 20 just upstream of a fluid-actuated reciprocable shear blade 52. An end gauging stop device 74 and one or more intermediate gauging stop devices 58 are adjustable along a feed channel 92 to set the desired cutting lengths. The normally pivotable stop 60 of the stop device 58 which, according to a preselected programme is to be effiective for the next cut length is held vertical by actuation of an electromagnet 64 controlled by unit 86. The stop 76 of the end device is fixed. The rod(s), having pushed aside the stops 60 of any intervening ineffective stop devices 58, pivot a switch gate 66 of the effective stop which actuates the fluid cylinder 54 operating the shear blade 52. As the cut is completed, a further electrical signal from the   stop device releases means holding the blade holder 52A vertical so that the rod(s) may push it aside as they proceed to the next effective stop. According to the programme, a fluidactuated guide finger (84), Fig. 6a (not shown), is moved to direct cut rods to piles of different length rods.

Abstract: 1391102 Discharge apparatus TEXAS INSTRUMENTS Inc 24 July 1972 [9 Sept 1977] 34528/72 Heading H1D A charged particle beam apparatus of the type wherein the flow of particles from an extended area source 11 to a target 15 is controlled by electrodes (not shown) arranged in finger patterns on the sides of apertured plate electrodes 12, is characterized by the provision of a collector plate 14 and a charge storage target arranged in that order between electrodes 12 and 15; preferably a further electrode 16 is provided between electrodes 13 and electrode 15 which may be a fluorescent screen. Electrodes 14 and 16 may be apertured plates with their apertures aligned with those of electrodes 12. Electrode 13 may comprise a metal mesh 13a with a dielectric coating 13b 1-5 microns thick. Alternatively it may comprise a metal plate with apertures aligned with those of electrodes 12 and coated with dielectric over its surface facing the cathode 11 and round the inside of the apertures (Fig. 6, not shown). A further construction comprises an apertured dielectric plate coated on the side away from the cathode and round the inside and the edges of the apertures with secondary emissive metal. In operation, signals are erased from the storage electrode 13 by reducing its potential below the secondary emission crossover potential and flooding it with electrons. During this mode electrode 16 is maintained negative thereby preventing excitation of screen 15 and so reducing its average brightness and increasing the contrast. In the write mode electrode 13 is raised above the cross-over potential and electrode 14 is somewhat higher so that negative charges are stored during the scanning. In the read mode, electrode 13 is brought near cathode potential (20v) and electrode 15 to 50 volts whilst the storage target is flooded with electrons so that electrons pass through it in accordance with the charges stored. As described the tube operates with electrons, but the use of positive or negative ions is also mentioned.
