Title: Apparatus for and method of horizontally stacking substantially flat articles
Inventor: DALEN CHRISTIAAN JOHANNES VAN
IPC: B65H31/38
Filed: 1966-05-02
Abstract: 1,144,522. Sheet delivery apparatus. NETHERLANDS, THE POSTAL & TELECOMMUNICATIONS SERVICES, DIRECTOR GENERAL OF. 2 May, 1966 [3 May, 1965 1 , No. 19145/66. Heading B6H. Apparatus for horizontally stacking flat articles comprises support members S, S1 which rest on rollers A, A1 and A1, A1<SP>1</SP>. Each pair of rollers A, A1 and A1, A1<SP>1</SP> is mounted on a shaft for common rotation and a chain-sprocket connection K, K1, K2, provides synchronous rotation of the pairs of rollers. Each roller has peripheral flats which are circumferentially displaced relative to the flats of the adjacent roller. A stop C is provided on the supports S, S 1 which are normally urged to the left of Fig. 1 by springs V, V1. The addition of articles at Z to a stack P causes the stack, stop C and the support S to move to the right and the rollers to be rotated by the support S. At the position shown in Fig. 4, the support is about to be lowered since the circumferential portions of the rollers are interrupted at b<SP>1</SP>, b1<SP>1</SP>. The support S is therefore returned to its original position by spring V and support of the stack P and stop C is taken over by the support S1 which is raised on to the circumferential portions of rollers A1, A1<SP>1</SP>. As it is moved to the right by the addition of further articles the support S1 rotates the rollers in a similar manner to support S. There may be two or more pairs of supports, Fig. 6 (not shown), arid the rollers may be profiled to improve the transfer of the stack from one support member to the other, Fig. 8 (not shown).

Title: Nuclear fuel elements
IPC: G21C3/16
Filed: 1966-05-02
Abstract: 1,110,657. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. 2 May, 1966 [20 July, 1965], No. 19170/66. Heading G6C. A fuel element comprises a long mass of ceramic fuel containing a relatively small amount of fissile material and a wire of a metallic fuel containing a relatively large amount of fissile material, the wire being in the form of a varying helix. The wire may vary continuously in pitch from a maximum at a mid region to a minimum at the ends of the wire, or vary continuously in helix diameter from a minimum at a mid region to a maximum at the ends of the wire. In the latter case, if the wire has a uniform pitch, the amount of wire/unit length of the fuel element varies from a minimum at the centre to a maximum at the ends. For the amount of wire/unit length to be constant, the pitch of the wire must in this case vary from a minimum at the centre to a maximum at the ends. In one embodiment, the helical wire extends along the longitudinal axis of a stack of annular sintered natural UO 2  pellets enclosed within a Zr alloy jacket, the remaining void space within the stack being filled with granular natural UO 2 . The wire may be of Pu- 15% by weight Zr alloy and may be bare or clad in a suitable protective material. The wire may contain U-233 or U-235 instead of Pu. Alternatively, the ceramic fuel comprises a mass of vibrationally compacted crushed natural UO 2 . In another embodiment, a helical Pu-containing wire of varying pitch is applied to the exterior of the fuel element jacket and serves either to provide initial enrichment of the fuel element or to re-enrich or rejuvenate the fuel element after radiation. The wire may be formed of a stainless steel or Zr alloy tube of small diameter, a Pu-containing wire within the tube, and a filler of MgO. The wire may serve to space the fuel element to which it is applied from other fuel elements.

Abstract: 530,229. Lubricators. BURGESS, A. F., (Scintilla, Ltd.). July 1, 1939, No. 19211. [Class 12 (iii)] An installation for lubricating the wheel flanges of rail vehicles and/or the guiding face of the rails comprises an oil supply pump continually operated while the vehicle is in motion and a valve in the supply system adapted through the relative angular displacement of the vehicle and a bogie therebeneath when the vehicle is rounding a curve to divert automatically the oil supply to lubricators adjacent the outer wheel flanges and rail but to bye-pass the oil back to the reservoir when the vehicle is on a straight track. As shown rotation of a carriage bogie 3 relative to the carriage 5 when rounding a curve produces through linkage 58, 60, 56 displacement of a sliding valve 30 which, operating on a straight track to bye-pass the oil supply from a pump 13 through conduits 33, 34 leading back to the oil reservoir, in a displaced position on a curved track shuts off the oil from all outlets except that, 35 or 36, leading to the outer wheel flange lubricator 49 or 50. The pump 13 is driven through gearing 7 and 8 by a shaft 6 driven from the carriage wheels, cam surfaces 18, 19 of an oblique groove 16 in the gear wheel 8 hub contacting with a projection 20 of adjustable effective breadth reciprocating the piston, which has a slot 27 therein to connect the cylinder chamber 28 alternately with (i) during a suction stroke, an inlet conduit 25 leading to the oil reservoir and (ii) during a pressure stroke, with an outlet port 26 leading to the valve 30. The linkage arm is rendered extensible by a spring device 63 to provide for turning of the bogie beyond the stroke limit of the valve 30. Preferably the lubricators 49, 50 are fitted with valves opening only at a definite pressure and there is a slight throttling of the oil supply in the valve at the bye-pass outlets even in a central position of the valve.

Abstract: 1294598 Photographic vesicular images using the silver salt diffusion transfer process AGFA-GEVAERT A G 22 April 1970 [26 April 1969] 19252/70 Heading G2C A photographic process for producing superimprosed silver and vesicular images comprises (a) imagewise exposing a supported silver salt emulsion layer (b) developing the layer whilst in contact with an image-receiving layer containing uniformly distributed development nuclei to produce a silver image in the receiving layer and (c) treating the receiving layer with a compound which is decomposed by the silver image to produce a vesicular image thereon. Hydrogen peroxide, as vapour or in solution, is the specified compound and is applied as in Specification 1196200. The light-sensitive emulsion may be a support coated, in either order, with a gelatine silver halide emulsion and an image-receiving layer containing silver sulphide or silver selenide, the concentration of silver halide and nulei being low (0À1-0À3g per sq m of silver as silver halide and 10<SP>-3</SP> to 10<SP>-4</SP> g per sq m of nuclei). There may be an intermediate algisate layer between silver halide and receiving layers. If the silver halide-emulsion is the top layer, it is washed off during development before the vesicular layer is produced. The vesicular image increases the density of the silver image.

Title: Improvements in devices for moulding coking materials
IPC: C10B45/02
Filed: 1930-06-25
Abstract: 357,591. Moulding fuel blocks. HILGER, G., 1A, Marienstrasse, Gleiwitz, Germany. June 25, 1930, No. 19367. [Class 87 (ii).] An apparatus for moulding blocks of coal dust &c. comprises a mould within which work perforated ramming-plates covering the whole cross section of the mould, the materials to be compressed being fed through the apertures in the ramming plates. The rammers 4, having apertures 5 may be carried by rods 11 working in cylinders 8 and provided with pistons 12, the cylinder ends being connected through a spring-loaded valve 14 so that the rammers apply a predetermined blow when the cylinders 8 are reciprocated and yield vertically to accommodate the increased height of the block. A crosshead 7 is provided with pins 6 which clear the apertures in the rammers at each reciprocation. The rammers and crosshead 7 may be actuated through linkage and an eccentric 10 by an electric motor. The platform 3 may be raised periodically by electrical control and in this case shorter cylinders 8 may be used. In a modification, the mould 1 may be caused to descend periodically. The rammer cylinders may be arranged horizontally and may communicate motion to the rammers through racks and levers, In a further modification a single ramming cylinder 8, Fig. 7, may be located between two moulds 1 and may actuate a crosshead 32 connected to the rammers 4 working in the moulds. Feeding devices 36 regulate the supply of material from a hopper 35. The mould and rammers may be shifted laterally relatively to each other to the extent of half the diameter of the apertures in the rammer, at each ramming operation to obtain a more uniform product.

Title: Improvements in or relating to feeding arrangements for display cathode ray tube deflector coil systems in radar and similar installations
Inventor: WARD RONALD ARTHUR
IPC: H03K4/26
Filed: 1953-07-13
Abstract: 736,183. Saw-tooth current-generating circuits ; radar. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 21, 1954 [July 13, 1953], No. 19415/53. Classes 40 (6) and 40 (7). The voltage obtained from the output valve of a deflection current generator for the display tube of a radar system is supplemented by a further voltage supplied by an auxiliary valve when the rate of change of deflection current exceeds a predetermined value for example during the flyback. The Figure shows a pushpull amplifier circuit feeding deflection coils DC1, DC2, negative feedback being applied through resistors R1 and R2. The rate of change of current through the coils during the flyback is so large that the output valves " bottom." Accordingly the feedback is interrupted and the input voltage to the output valves V3, V7 increases. This increase is sufficient to render auxiliary valves V4, V8 conducting and as they are connected to a negative supply the voltage across the coils is increased. The circuit permits a more rapid flyback to be obtained and thus facilitates the introduction of interscan marker pulses such as IM (Fig. 3).

Title: Process for the manufacture of phosphorous sulpho-chloride
IPC: C07D405/12
Filed: 1960-06-02
Abstract: Phosphorus sulphochloride, PSCl2, is manufactured by reacting powdered, or granular, sulphur and phosphorus trichloride, PCl3, in liquid phase, with a metallic aluminium or aluminium alloy catalyst and stirring, at the boiling temperature of PCl3 and atmospheric pressure, wherein the S and PCl3 are added in successive stoichiometric proportions in the presence of a quantity of PSCl2 as medium and moderator at the commencement of the reaction, and PCl3 is simultaneously refluxed back into the reaction mixture.  The reaction is a batch process and the weight of PSCl2 present should be at least 3 times the weight of the first S addition. Chippings or small waste of aluminium or alloy are used in excess of 3%.  A small excess of PCl3 is added during the last stages of the reaction to ensure absence of unreacted S.  When the capacity of the reaction vessel is exhausted, excess PCl3 is distilled off, followed by PSCl2 at 124 DEG -126 DEG C., until a residual fraction is left in the reaction vessel sufficient for the next batch.

Title: Improvements in or relating to relaxation generators of the free running type
IPC: H04J3/14
Filed: 1961-05-31
Abstract: 948,025. Transistor pulse circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 31, 1961 [June 3, 1960], No. 19651/61. Heading H3T. In a relaxation oscillator, a transistor is biased into the conductive state and the positive feedback path between the control electrode and the relaxation capacitor is closed via a diode, normally rendered non-conductive by the bias on the control electrode. As shown, a transistor 1 has positive feedback via transformer 2 and diode 9. In the absence of pulses at point 24, the relaxation capacitor 3 charges negatively via resistors 21, 23 until the voltage developed at the junction of resistors 7, 8 is reached, when diode 9 becomes conductive, closing the positive feedback path so that the circuit executes a half-cycle of oscillation. Capacitor 3 is discharged via the transistor 1 and the diode 9, whereupon the diode becomes biased off until the capacitor C is recharged again. The base current is limited by resistor 10 and diverted via diode 11 when excessive. The transistor characteristics have less effect on the operation than in a conventional blocking oscillator and the diode 9 prevents base leakage current interferring with the charging of capacitor 3. Fig. 1 (not shown) relates to a free-running oscillator as described. Detecting failure of pulses.-Pulses to be supervised are fed to terminal 24, each pulse rendering transistor 15 conductive and discharging capacitor 3 before it reaches the voltage required to cause transistor 1 to oscillate. If the pulses at 24 should fail, transistor 1 begins to oscillate and energizes relay 25 which is latched by unspecified means and operates an alarm 27. A plurality of pulse generators, each connected to individual circuits 29 may be supervised by a single oscillator of the type shown.
