Title: Improvements relating to purging apparatus for gas-filled enclosed equipment and particularly to fuel handling equipment for gas cooled nuclear reactors
Inventor: JAMESON GEORGE ROBERT KENNETH
IPC: G21C19/02
Filed: 1958-03-17
Abstract: 875,450. Handlingnuclear reactor fuel elements. A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd. March 10, 1959 [March 17, 1958], No. 8552/58. Class 39(4). A sequence control apparatus for pressurising with gas a fuel element or shoot charging machine such as disclosed in Specification 854,764 comprises a cam (Figs. 2, 3, not shown) controlling a plurality of electric switches some of which are also operable by particular pressures existing in the charging machine, this cam being driven by an electric motor together with further cams controlling switches for energizing valves V2, V3, V4. The two-way valve V2 permits the exhaust to be. directed through a vacuum pump or to bypass it. The sequence of operations is commenced by pressing a button whereby the machine is pressurised to a low pressure P2 (Fig. 2 not shown) from a CO 2  supply duct; the valves V3, V4 both being open. The pressure P2. causes one of the gas-pressure operated switches to energize the motor and index the sequence control apparatus one step whereby the valve V3 is closed and the pressure in the machine drops to atmospheric pressure P3 (Fig. 2 not shown). The pressure P3 causes another gas pressure operated switch to index the control apparatus one step whereby valve. V2 is connected to -the vacuum pump and the pressure in the machine drops to a vacuum P4 (Fig. 2 not shown). A further switch is operated by the-pressure P4 to index the control apparatus a further step whereby the valve V3 is opened and valve V4 closed and the machine is pressurised to a pressure P1 equal to that in the reactor. The pressure P1 (Fig. 2 not shown) actuatesa. further switch to index the control apparatus a further step and a fuel charging operation may now be performed. The push button is again depressed to index the control apparatus a further step whereupon valve V3 is closed, 'valve V4 opens and valve V2 by-passes the pump. The pressure in the machine drops to P3 and the control apparatus is indexed into its initial position.

Title: System for determining the nature of optical distortion in glass
Inventor: OBENREDER R
IPC: G01N21/41
Filed: 1974-02-26
Abstract: 1466118 Investigating sheet glass PPG INDUSTRIES Inc 26 Feb 1974 [31 May 1973] 8602/74 Heading G1A In a device for investigating variations in surface contours and variations in the refractive index of a moving glass sheet 12, both sides of the glass sheet are scanned by light from lasers 22 or 39 directed via a polarization filter attenuator 26 or 42 on to the surfaces 12, 18. The reflected light is received by detectors 30, 46 whose output varies in dependence upon the position of the centroid of the incident beam on its sensitive surface. Thus slight variations in the surface contours will cause corresponding movements of the corresponding light beam on the detector's sensitive surface. Variations in the refractive index of the glass sheet combined with the surface contour variations are measured with the aid of a further position sensitive detector 58 placed to receive the light passing through the sheet from one of the sources 22. All three detectors are processed as shown, Fig. 2, each signal passing via a preamplifier 86, a function generator 84, an attenuator 88 on a differentiator 94 to feed a strip recorder 100. The surface contour signals are also added together by an Adder 108 to provide a "total surface profile signal" Figs. 3, 4, 5 (not shown) whose output is fed to the strip recorder and to a subtraction circuit 116 which also receives the processed signal 120 from the further detector 58, the transmitted light, to provide an "internal distortion signal", refractive index variations. The attenuators 88, 96 and 98 are adjusted so that the summed surface contour signals 118 from the adder circuit corresponds in magnitude to that part of the transmitted signal 120 due to the effects of the surface contours. Thus the output 122 of the subtractor circuit is proportional to variations in the refractive index of the sheet. The description mentions that the glass sheet could be stationary and the source and detector moving and the description derives several equations relating to the measurements.

Title: Improvements in or relating to track-tensioning means for an endless track assemblage of a "crawler" type vehicle
IPC: B62D55/30
Filed: 1957-03-18
Abstract: 810,073. Endless track vehicles. INTERNATIONAL HARVESTER CO. March 18, 1957 [March 19, 1956], No. 8798/57. Class 79(1) Track-tensioning means for a "crawler" type vehicle comprises a hydraulic ram 48, Fig. 2, disposed between a thrust member 22, Fig. 1, on a track idler wheel 15 and overload release means 44, 45, a hydraulic accumulator 58 communicating with the ram through a non-return valve 65, and means for maintaining a predetermined pressure in the accumulator, and consequently in the ram, to maintain a predetermined tension on the endless track. If the tension on the track is increased, for example by the passage of an object between the track and its roller 28, a bear ing head 18 carrying the idler wheel 15 is displaced on guides 21 and the member 22 displaces the ram 48 to the left against the pressure of the springs 44, 45. The ram cylinder contains a pump cylinder 84 which moves with it relatively to a plunger 89 to transfer oil from a chamber 35 to the accumulator 58, the pressure in the latter and hence in the ram being determined by a relief valve 75 adjustably loaded by a spring 73 and a screwed, fluted plug 74. To charge the accumulator and the ram, a vent plug (not shown) is removed from the ram cylinder and the plunger 89 reciprocated by manual rotation of an eccentric 94 until the ram cylinder is full when the vent plug is replaced. Further reciprocation of the plunger 89 displaces the ram piston 54 to apply the desired tension to the track 12. The pump draws the oil through a filter (not shown) and non-return valves are provided in the cylinder 84 and the plunger 89. In Fig. 7, leftward movement of a ram 121 carrying an idler wheel 118 reduces the volume of a chamber 112 co-operating with a fixed tubular plunger 134a to displace fluid through a non-return valve into an accumulator 115 which is connected by a further non-return valve to the ram. The plunger is connected by an adjustably loaded relief valve 111 and a non-return valve 129 with a reservoir 127. In both constructions the pump may be operated intermittently or periodically by relative movements between parts of the vehicle consequent on fluctuations or reversals of tractive effort or on inequalities in ground level or, it may be driven from the vehicle power plant. The accumulator may be of the spring-loaded type.

Title: Improvements in photocells
Inventor: SCHWARZ ERNST
IPC: H01J40/00
Filed: 1948-03-25
Abstract: 685,288. Discharge apparatus. HILGER & WATTS, Ltd. March 16, 1949 [March 25, 1948; May 31, 1948], Nos. 8867/48 and 14115/48. Class 39(i) [Also in Group XL(b)] In the production of a photoelectric cell of the photo conductive type in which the light-sensitive layer consists of a compound containing at least one metal, the photo cell is formed by vaporising the compound or a metallic constituent thereof at a pressure considerably below atmospheric for deposition on a carrier and subjecting the material while in the vapour phase to an electric discharge in the presence of a gas, e.g. oxygen or air, capable of being adsorbed on to the particles of the vaporised material. The process may be carried out in apparatus in which the particles of the substance are produced in the space containing the ions of the gas to be adsorbed. Apparatus for producing separately the gas ions and those of the substance to be deposited is shown in Fig. 6 in which a vessel 23 in the shape of a T has a stem portion including a coil 24 producing electrons and grid electrodes 25, 26 maintained at progressively increased voltages, the gas being admitted at the inlet 3 adjacent the space between the grids. The right-hand branch of the T carries a coil 27, an accelerating grid 28 for the electrons and a heating coil 29 for the substance 13 to be deposited. Accelerating grids 30, 31 for the positive ions of the vaporised substance are held at progressively increased negative voltages, and an atmosphere of inert gas, e.g. nitrogen, is maintained by inlet and outlet tubes 32. 35 to isolate the material 13 from direct attack by the treatment gas, and the carrier 6 is mounted on a support 36 through which cooling liquid may be circulated. In other forms of apparatus a sputtering process is imployed, Fig. 1 (not shown), in which a cathode carries or is composed of the metal or compound and coils are employed to deflect the bombarding electrons from the carrier on which the substance is to be deposited. In another form, Fig. 2 (not shown) the substance is carried by a heater coil disposed between the anode and cathode, and in a further arrangement, Figs. 3, 4 (not shown), the substance carried by a coil to which suitable voltages are applied is subjected to bombardment by negative gas ions and electrons and carriers for the deposited layer are mounted above a cooling chamber. In a further arrangement, Fig. 5 (not shown), which may combine sputtering and a low voltage arc, the cathode is formed of one of the metals to be deposited with other substances in cups forming the arc. The cathode may consist of a non- sputtering metal e.g. aluminium, with different substances in the two cups.
