Title: Container for transporting radioactive materials
IPC: G21F5/005
Filed: 1973-01-30
Abstract: 1423561 Transportable shielded containers S L REESE 30 Jan 1973 4680/73 Heading B4Q A container for transporting radio-active materials, e.g. spent fuel elements or radioactive waste, comprises a cavity 1 surrounded by a beta-gamma radiation absorbing material 3, e.g. depleted uranium, and an outer wall 6 on which fin plates 10 are detachably mounted by means of bolts 16. The fin plates 10 each have fins 14 permanently affixed to a base-plate 12. Corrosion-resistant cladding 2, 4, such as stainless steel, covers both the internal and the external walls of the shield material 3. Neutron shielding is provided by filling the space between the cladding 4 and the outer wall 6 with borated water. The fin plates 10 are removed during loading and unloading and, therefore, need not be constructed of a material resistant to corrosion by decontaminating solutions. They are preferably constructed of Al or Al alloy. Where neutron shielding is not required, the fin plates 10 are mounted directly on the cladding 4. A conventional road trailer 20 is shown in Fig. 3 having a platform 22 on which fin plates 24 are pivotally mounted. A smooth exterior wall container 30 of similar construction to that shown in Fig. 2, but without fin plates, and containing radio-active material is placed in position on the platform 22 and the fin plates 24 are then assembled around the container, as shown in dashed lines. An alternative transportation vehicle (Fig. 6, not shown) takes the form of a trailer, the frame of which includes two longitudinally extending spaced apart parallel beams between which the container is supported by two yoke means interconnecting the beams. This trailer is so constructed that should the container/vehicle assembly be subjected to a free fall, it is the vehicle structure and never the container which contacts the ground. The large impact forces resulting from the fall are thus prevented from acting directly on the relatively weak container corners and edges and so the risk of container damage is minimized.

Title: Data processing systems
IPC: G06F9/38
Filed: 1976-02-06
Abstract: 1506972 Pipelined data processors INTERNATIONAL COMPUTERS Ltd 31 Jan 1977 [6 Feb 1976] 04684/76 Heading G4A A plurality of registers 21, Fig. 4, and associated flags 26 are connected in sequence so that the contents of each register and flag can be shifted to the next register and flag in the sequence. The output 31 corresponding to each register 21 is taken from that register if the associated flag is set, and is taken from the first following register with a set flag (over line 33) if the associated flag is not set. The registers are intended for use as machine registers (accumulator, program counter, stack front pointer, program status) in a pipelined data processing system, the contents of the registers and associated flags being shifted along the pipeline in synchronism with the advancement of the corresponding machine instruction and operand and control data along a pipeline of buffer units BU, Fig. 1. Each stage of the pipelined processing system includes a processing unit PU for instruction fetch, stack operand fetch and so on. Each processing unit can selectively read and write into any machine register contained in the associated cells 20 (which include the flags and controls) and when writing sets the appropriate M flag 26 to indicate that the data is valid. If an instruction entering the pipeline at stage 1 is such that it will cause updating of a machine register at a later time, an additional W flag is set, Fig. 9 (not shown), and is shifted along the pipeline with the contents of the associated machine register. As the W flag moves along, the W flags of all the corresponding preceding machine registers are set and remain set until the associated machine register has been updated. If a processing unit attempts to read a machine register having a set W flag, it is prevented from doing so and the pipeline is "frozen" from the stage to the beginning of the pipeline until the update has taken place. Provision is also made for a processing unit to reset all M flags up to a particular stage, e.g. for a synchronous interrupt or to cancel a wrongly predicted jump instruction.

Abstract: 199,074. English Electric Co., Ltd., and Barnholdt, C. F. Feb. 17, 1922. Systems depending on the use of two or more motors.-Electrically propelled vehicles such as tram cars which are intended to work either singly or coupled together have their controllers arranged with additional switch devices so that the motors on all the vehicles can be directly controlled from either end of a particular vehicle. Fig. 1 shows the circuit arrangement of a single vehicle equipped with two motors 1, 2 adapted for series parallel working. At each end of the car is a main series-parallel controller 5 and a reversing switch 6, the diagram showing all the contacts of those at the left hand end and only the stationary contacts of those at the right-hand. By closing one or the other of two connecting switches 11, 12 either end of a car is prepared for coupling to a leading car, or by leaving both switches open is prepared for coupling to a trailing car. The reversing switch at the selected driving-end of the leading car is moved to a position in which the corresponding controller is connected to the motors of its own car and also to a triple cable 13, 14, 15 running through the length of the car, and joining by means of flexible couplings with the cable and motors of the trailing car. To ensure correct setting of the switches, one removable handle only is provided for the two connecting switches and two reversing switches on each car, and the handle is looked against removal when the connecting switch is closed. In the leading car the starting resistance, 9 is parallelled by an equal resistance 10 in order to pass sufficient current for the motors of both cars.

Title: Improvements in or relating to object locating and detecting apparatus
IPC: G01S7/18
Filed: 1946-02-26
Abstract: 594,788. Radiolocation. HOPKINSON, K. Feb. 26, 1945, No. 4827. Drawings to Specification. [Class 40 (v)] Elevation is indicated in a pulse-type object locating system by causing the direction of maximum sensitivity to scan over a chosen angle in a vertical plane and displaying received. echo signals as intensity modulations of radial range time base traces on a cathode ray tube, the angular movement of the radial time base being a magnified version of the angular variation of the direction of maximum sensitivity. The aerial, in a pulse radar system, is arranged to rock on a horizontal axis and the C.R.O. deflection system, which may be of the conventional external magnetic type, is rotated in synchronism. The drive between the deflection system and the aerial may be electric, e.g. selsyns or mechanical and suitable gearing is interposed so that while the aerial oscillates through 20 degrees the radial time base rotates through 180 degrees. In addition to circular and radial markings indicating range and elevation, the screen of the C.R.O. may be provided with curved markings related to constant heights of chosen values. It is stated that the invention may be applied to radar systems with stationary stacked aerial arrays in which the directivity is controllable by variable phase-adjusting networks.

Title: A process for polymerising unsaturated compounds in the emulsified state
IPC: C08F14/06
Filed: 1947-02-20
Abstract: Unsaturated organic compounds containing a C=C group or mixtures thereof are polymerized in aqueous emulsion by passing them continuously through a reaction apparatus and adding fresh monomeric materials which, if not already emulsified, becomes so in the emulsion to which they are added, at one or more places along the path of the emulsion through the apparatus.  Preferably, the supply of fresh monomer is in the form of a concentrated emulsion. Specified unsaturated compounds are vinyl and vinylidene chlorides, vinyl acetate acrylic and methacrylic acid esters, styrene and fumaric acid esters.  The reaction apparatus may consist of a series of at least four chambers fitted with stirrers, the average time the emulsion remains in any one being not more than an hour.  The invention allows polymerization to be carried out at temperatures lower than usual, e.g. vinyl chloride at 20 DEG  C.  Homogeneous products are obtained by maintaining the temperature constant throughout the polymerization.  It is preferred that the pH of the reaction system is unchanged by the addition of fresh monomer.  The polymerization velocity is increased by use of a catalyst combination consisting of persulphuric acid or a water-soluble persulphate and a water-soluble substance capable of absorbing oxygen, e.g. sulphurous acid and its water-soluble salts, hydrosulphites, dithionites, metabisulphites, hydroxylamine, hydrazine, thioglycolic acid and water-soluble salts thereof.  If desired, a product derived from the components of the catalyst may be used, e.g. the product of the action of sulphur dioxide on an aqueous persulphate solution. Specifications 573,366, 573,369, 578,584, 590,816 and 619,513 are referred to.  The Specification as open to inspection under Sect. 91 comprises the use of ethylene, vinyl and vinylidene halides, acrylic and methacrylic nitriles, maleic acid esters, butadiene, chloroprene and chlorinated styrenes as unsaturated compounds to which the process is applicable.  This subject-matter does not appear in the Specification as accepted.

Filed: 1953-02-26
Abstract: 741,430. Pulse generating circuits. GENERAL ELECTRIC CO., Ltd., and LITTLE, J. G. Feb. 15, 1954 [Feb. 26, 1953], No. 5449/53. Class 40 (6). Fig. 1 shows a circuit for generating sequentially a series of pulses in which a pulse generator 10 generates a train of rectangular pulses having a recurrence period of 125 Á secs, and a duration of 5 Á secs, and a further pulse generator 15 which is synchronized from generator 10 and generates a train of rectangular pulses of recurrence period <SP>1</SP>/ 26  that of generator 10, i.e. 4.81 Á secs. and of 0.5 Á secs. duration. The two pulse trains are applied to the low-pass filter delay network 1 which has 26 output tappings T1 ... T26 spaced along it at 4.81 Á secs. intervals, each pulse from generator 15 causing the potential of the whole of network 1 to be raised for its duration. As each pulse from generator 10 appears at tapping points T1-T26 a pulse from generator 15 is superimposed on its midpoint, Fig. 3 (b) (not shown), and the resulting pulses of enhanced amplitude are clipped by pulse forming networks PF1 ... PF26 to produce a pulse at the corresponding output, Fig. 3 (c) (not shown). The clipping circuits may each comprise a biased crystal diode associated with a gate for deriving widened pulses from the output of the clipper, Fig. 2 (not shown). In a modification, the pulse generator 10 is replaced by a crystal-controlled sinusoidal oscillator having a frequency equal to the recurrence frequency of pulse generator 10. The output of each tapping T1 ... T26 then comprises a pulse superimposed on a sine wave of a phase characterized by the respective output tapping as shown in Fig. 5 (a), the pulse forming circuits PF1 ... PF26 may then each comprise, as shown in Fig. 4, a bi-stable trigger circuit which generate a square wave, Fig. 5 (b), of the same frequency as the sine wave and having its trailing edge accurately positioned by a superimposed pulse from generator 15. The trailing edges of each pulse generated by the trigger pair circuit comprising double triode 35 shock-excites tuned circuit 43 to produce an output pulse as shown in Fig. 5 (c). In a further modification, shown in Fig. 6, the phase-shifting network 50 comprises a high-pass filter, a sinusoidal wave having a period of 125 Á secs. is generated by unit 63 and the pulse generator 61 has a recurrence period of 4.81 Á secs. The circuit functions similarly to that already described except that the sinusoidal wave which appears along the network 50 will be advanced in phase with respect to that applied from generator 63.
