Title: Improvements in or relating to compressed air brake systems for railway vehicles
IPC: B60T8/18
Filed: 1958-12-09
Abstract: 870,842. Fluid pressure braking systems. SVENSKA AKTIEBOLAGET BROMSREGULATOR. Dec. 9, 1958 [Dec. 9, 1957], No. 39687/58. Class 103 (1). A railway fluid pressure braking system has a lower or higher braking effort set by a fluid pressure servomotor controlled by a three-way valve operating in response to vehicle load. The valve 1 comprises a member 4 having a base 6 formed with a rim 8 for engagement with a member 15 carried by a diaphragm 13 and biased against an annular rim 17 on an insert 7 by spring 18. The member 4 is biased away from member 15 by a spring 9 to a position in which a collar 11 engages a flange 10 of the valve housing; a diaphragm 12, clamped between insert 7 and the housing, engages member 4 adjacent collar 11. The valve is connected to a fluid pressure source (5 kg/cm.<SP>2</SP>) via port 3, to the servomotor via port 2, and to atmosphere via bore 16 in member 15 and restricted port 14a in plug 14. A lever 23, connected by linkage to a vehicle spring, bears on the head 5 of member 4 and on a dashpot 24. Normally with insufficient load to depress the dashpot 24, the valve is maintained as shown by springs 9, 18, the servomotor being vented to atmosphere via port 2, groove 19 in insert 7, past base 6 and through bore 16, for lower braking effort. When the vehicle is loaded sufficiently to overcome the bias of dashpot 24, the member 4 is depressed to seat rim 8 on member 15 to cut off the atmospheric connection, and then move member 15 from rim 17 to supply fluid pressure to the servomotor via ports 3 and 2 to set the brake for the higher braking effort. On unloading, the springs 9, 18 move members 4, 15 upwardly until member 15 engages rim 17, movement then ceases until further unloading to permit member 4 only to be moved. The areas of the valve acted on by the pressure from port 3, are such that they subject the members 4, 15 to a force during movements from the load to noload positions and vice versa to aid such movements and tend to maintain the members in that position, the diameters of the effective pressure area of diaphragm 12, must be less than the area bounded by edge 17 and less than the area bounded by edge 8 minus the cross-sectional area of member 4 where it is surrounded by diaphragm 12, the diameters of edges 8 and 17 being approximately equal; the diameters of the effective area of diaphragm 13 and of ridge 17 being approximately equal. Specification 554,657 is referred to.

Filed: 1964-09-30
Abstract: 1,072,295. Cigar-making machines. K. KÍRBER. Sept. 30, 1964 [Nov. 7, 1963], No. 39801/64. Heading A2C. The end portion of a cigar or cigarillo bunch, or of a filler rod or a cigar or cigarillo is moistened after drilling and before moulding. The rod or bunch 1 is located in line with a sleeve 2 which is provided with ducts 4 through which water, which may be heated, can pass from a chamber 5. The chamber 5 is filled with a sponge-like material, to which water is supplied from a supply line 6 having a non return valve 7. The water is forced from the sponge on to the cigar rod or bunch by compressed air through a pipe 12, chamber 9 and bores 10 and 11. A drill 14 is provided for drilling the rod or bunch prior to moistening. A suction tube 17 having a valve 18 is provided for removing the drillings. In operation, the sleeve is advanced to the dotted line position and the drill driven into the end portion of the rod or bunch. At this time valve 18 is open. After drilling the drill is withdrawn, valve 18 closed, and liquid injected into the end portion of the rod or bunch by application of compressed air through pipe 12. The valve in pipe 12 is then closed and the sleeve 2 withdrawn from the end portion. A similar, opposite ended, device may be provided for the other end of the bunch.

Title: Explosively-actuated stud-driving tool
IPC: B25C1/14
Filed: 1963-10-11
Abstract: 981,938. Cartridge-operated tools. OMARK INDUSTRIES Inc. Oct. 11, 1963 [Feb. 1, 1963], No. 40210/63. Heading B4C. A cartridge-operated tool for driving studs 28 or like fasteners into hard materials comprises a piston P slidable in a barrel 13 and a ram R having a shank portion slidable in a guide 27 and a head portion 26 adapted to be connected to the piston. The barrel 13 is slidable in the housing 10 of the tool and is provided with a slot 30 in which a key 31 connected to the guide 27, is movable; the key is provided with a finger portion 31<SP>1</SP> having a limited axial movement in a slot 33 in the housing. The head portion 26 of the ram R is formed with a hook-shaped end 25 adapted to engage with a correspondinglyshaped slot 29 in the piston P so that, when both ram and piston are contained within the barrel, they are securely connected together. In operation, to load the tool with a cartridge C, the barrel is pulled forward to the position shown in Fig. 4 so that a cartridge can be inserted into its bore 14 via an opening 12 in the housing; due to the co-operation of the key with the slot 33, the guide presses the piston into its rearmost position. The barrel is then pushed back to the position shown in Fig. 5. In order to fire the tool, the outer end of the barrel is pressed against the work by means of a handle 11 thereby causing the inner end of the barrel to urge the breech 15, against the action of a spring 16, into the cocked position. By depressing a trigger 23, the firing pin 19 is released to fire the cartridge and so drive the piston forward. The cartridge case is ejected when the gases trapped between the piston and inner end of the barrel are compressed as the barrel is again pulled outwardly; additionally, a spigot 42 is provided on the piston to enter the cartridge bore 14. In order to remove the piston and ram for repair or replacement, a spring-loaded pin 34, which normally maintains the key 31 in contact with the slot 33, is withdrawn so as to allow the key to enter a slot 32 in the housing; the key is then able to drop out of engagement with the guide 27. To prevent damage to the ram and piston due to over-travel of the latter, the key is adapted to partially fall out of engagement with the guide after the key abuts a surface 30<SP>1</SP> on the barrel.

Title: Measurement of the position of a surface
IPC: G01B11/06
Filed: 1974-09-06
Abstract: 1484996 Measuring position of a surface UNITED BISCUITS (UK) Ltd 6 Sept 1974 [24 Aug 1973] 40262/73 Heading G1A The variations in level of a surface across its area, are monitored photo-electrically by projecting a pattern or area of light on to the surface and sensing the transverse shift of the reflected pattern by a strip array of photodiodes which is repetitively electronically scanned. The source of light may be a conventional tungsten filament or a tungsten-halogen lamp, a laser, and may be associated with a slit, straight edge &c. and a lens to produce a sharp outline image on the surface. The image may be a wide area, a thin line or two discrete linear areas, Fig. 4 (not shown). Light may be directed by mirrors on to the surface and reflected light may be magnified, x4, on to the photodiode array.  The output of the photodiode array, which is repetitively electronically scanned is, in one arrangement, fed to a level detector which produces a squarewave output varying in mark-space ratio in dependence upon the instant of time in each scan that a datum level is reached, i.e. a level representing illumination of a diode. The squarewave is smoothed to obtain a voltage proportional to the average pulse duration which is displayed on a meter and is proportional to the level of the surface. When this is referred to a reference plane, the thickness of the object the top surface of which is being monitored, is given. Other circuit facilities could include a C.R.T. display or a computer.  When two sides of the object are monitored e.g. by use an additional complete system or of extra mirrors and lenses and a further photoelectric arrangement, thickness is measured from the combined, summed, signals. The objects may be biscuits moving on a conveyer belt.

Filed: 1974-09-17
Abstract: 1476693 Automatic focusing CORNING GLASS WORKS 17 Sept 1974 [21 Sept 1973] 40426/74 Heading G1A [Also in Division G3] In an automatic focusing device, radiation from a source 12 is directed as shown via lens 14 and 16, a slide to be investigated 10 and an adjustable lens 18 to a semi-reflector 20. The semi-reflector 20 splits the radiation so that it forms an image plane at 28, where the slide image is processed with a T.V. camera as in Specification 1456317, and at an image plane between two photo-cells 32, 34. The photo-cells 32, 34 are positioned, with associated masks 36 and 38 to be in front of and behind the "ideal" position of the image plane. The radiation is caused to scan the photo-cells by a rotating mirror 44, and the photo-cells' output are differentiated and fed to a comparator 46 which, if the cells are not equally illuminated, controls a stepping motor 50 to adjust the lens 18. The adjustment is effected by means of an arrangement consisting of a spring-loaded worm gear 52 that rotates an eccentric member 54 which has a roller bearing 56 pressing against a protrusion 58 on the objective lens holder. In a modification, a "50-50" beam-splitter prism Fig. 2 (not shown), is positioned between the rotating mirror 44 and the detectors. This ensures that each photo-cell receives exactly the same image. A detailed construction Fig. 3 (not shown) of the mechanism connecting the stepping motor 50 to the objective lens holder is described.

Title: Nuclear reactor
IPC: G21C9/00
Filed: 1973-09-03
Abstract: 1417638 Cooling nuclear reactors WESTINGHOUSE ELECTRIC CORP 3 Sept 1973 [13 Sept 1972] 41358/73 Heading G6C In a nuclear reactor (e.g. a liquid sodiumcooled fast breeder) an hydraulic flow controller is provided in the cooling circuit and functions so as to minimize loss of coolant in the event of a breach in part of the circuit external to the reactor vessel. In one embodiment (Fig. 2) the cooling citcuit includes two identical loops external to the reactor vessel, each loop comprising a heatexchanger and circulation pump. The loops connect with the reactor vessel 4 at respective inlet nozzles 5, the separate flows being conducted to the flow controller which is in the form of a velocity chamber 6. A zone of mixing of the flows within the chamber 6 has a crosssectional flow area lower than the total crosssectional flow area of both conduits 3 by which coolant is conducted to the chamber 6. Thereby, the velocity of flow in this zone is increased, and the static pressure correspondingly decreased, relative to their values in the individual conduits 3 of the separate loops. The lower static pressure within the chamber 6 minimizes the pressure differential between the chamber and any rupture in a conduit 3, thus resulting in a minimal loss of coolant from the rupture if the circulating pump is quickly stopped. Downstream of the mixing zone, the cross-sectional flow area increases, resulting in a reconversion of the flow velocity to static pressure before the coolant enters the core 7. A protective vessel 11 surrounds the lower portion of the reactor vessel 4 so as to trap coolant, in the event of rupture of the vessel 4, thereby to ensure core submergence. In another embodiment (Fig. 3a) the flow controller comprises a vortex chamber 14 and three separate coolant loops are provided externally of the reactor vessel, each loop entering the chamber 14 at one of three tangential nozzles 15. For the purpose of reconverting the flow velocity to static pressure, a radial diffuser 16 is provided at the outlet of the vortex chamber 14, the outlets of the diffuser including flow-straightening vanes 17.

Abstract: 951,482. Detecting dielectric losses. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 13, 1962 [Nov. 20, 1961], No. 41505/61. Heading G1U. A circuit arrangement for detecting dielectric loss in a specimen O consisting at least partly of dielectric includes an A. C. bridge and a cathode ray tube. The tube has one plate 1 of the pair 1 and 2 connected to the corner 10 of the bridge, between the bridge arm containing the specimen and a bridge arm containing a variable capacitor in parallel with a variable resistor, and the other plate 2 of the pair is connected to the corner 5 of the bridge between the other two arms, which are capacitive. The other pair of deflecting plates 3 and 4 are connected to two points 11 and 12 on a voltage divider which is supplied from the same A.C. source 8,9 as the bridge. The voltage divider P1, P2 may have an intermediary point 13 earthed, and the corner 10 of the bridge may also be earthed. In a second embodiment (Fig. 2, not shown) the voltage divider may be capacitive. In operation the bridge is first balanced at a voltage below the ionisation or internal discharge threshold of the specimen so that the trace appearing on the screen is a straight line. The supply voltage is then increased to a value which causes ionisation; this causes the trace to form a figure in the shape of a parallelogram, the area of which is a measure of the energy discharged per cycle. Thus the balance below the ionisation point permits the determination of the capacitance of the specimen and a "normal" resistive loss while the area of the figure produced after raising the test voltage indicates an additional loss due to ionisation or internal discharge phenomena. Specification 894, 943 is referred to.
