Title: Improvements in or relating to apparatus for positioning a tool relative to a plurality of articles
IPC: B23Q35/12
Filed: 1959-07-22
Abstract: 894,562. Soldering; wrapping wire; wiring circuit boards. WESTON ELECTRIC CO. Inc. July 22, 1959, [Aug. 7, 1988] No. 26090/59. Classes 83 (2) and 83 (4). [Also in Group XXXVIII] A device for positioning a tool relative to a number of articles fixed in space comprises means for moving the tool, scanning means for sensing the articles as the tool is moved, means for memorizing the positions occupied by the tool as each article is sensed and means responsive to the memory for moving the tool to a memorized position. In the embodiment the tool is a wirewrapping gun and the object is to make connection between certain ones of the terminals 32 in a battery. The wire-wrapping gun 24, Fig. 2, is mounted upon a carriage 12 and can be moved towards and away from a frame 14 by means of a solenoid 27 and a spring 29. The carriage also carries a light source 31 and a photo-cell 30, coaxially mounted and positioned so that the terminals 32 interrupt the light beam as the carriage 12 traverses guides 21, 22. Energization of a drive motor 11 (see also Fig. 1), traverses the carriage 12 from left to right and rotates a binary code disc in a housing 34a, which emits signals representing the position of the carriage on the guides 21, 22. Light to the photocell 30 is successively interrupted by the columns of terminals 32 causing successive energization of information transfer relay circuits 35-41 through a stepping selector switch 42. Each time one of the relays 35-41 is energized, signals from the encoding disc 34 are recorded, passing via brushes 44 and switch 45, to the next available one of the memory resisters A-G, each of which comprises nine relays. After traversing the guides the carriage operates a device 199, Fig. 2, which reverses the polarity of the motor and returns the carriage, at a higher speed, to its start position. Before the second run-through switch 45 is moved to " locate " so as to direct signals from the disc to a coincidence circuit 46. Switch 47 is closed via a " return " button to start the second traverse of the carriage, and the appropriate transfer relay is energized to transfer information stored in its memory register to temporary storage units 49-57 and applied to the coincidence circuit. This allows the carriage to move until the number stored in units 49-57 corresponds to the signals received from the disc 34, when it stops the drive motor. The carriage will now have overshot its required position, due to its momentum, but it is returned slowly and precisely positioned. The wirewrapping gun is operated by hand, and a further button is pressed to allow the next column of terminals to be located. Instead of a wrapping gun a wire-welding gun or other tool could be used.

Abstract: 600,050. Making ironing-apparatus. McGRAW ELECTRIC CO. Oct. 1, 1945, No. 25452. Convention date, April 2. [Classes 83 (ii) and 83 (iv)] [Also in Groups XI and XXXVII] Soldering.-A laundry iror comprises a planar electric heating element 37 in a recess 57 in the bottom surface of a top plate 35 fitting over a thin metal sole plate 33, the peripheries of the plates being joined by brazing material 84. Assembly plugs 71, 73 projecting through the top plate are brazed at 86 to the sole plate. An asbestos cord 79 round the heating element fits in the shoulder of the recess 57 and prevents brazing material 84 reaching the element. When assembled, the top and sole plates and plugs with the brazing material are heated to about 1300‹ F. clamped under a pressure of about 1000 Ibs. so that the plates, which may be brass, begin to soften and compress the element. Air between the plates escapes through an aperture 96 subsequently plugged. The clamps are removed when cooled to 600- 800‹ F., and when the plates are at room temperature, the peripheries are machined. The sole plate and peripheries are then plated. A casing, handle and thermal switch are then attached by screws. Riveted joints.-The brazed-in assembly plugs are swaged into place forming shoulders 89 over the top plate.

Title: Improvements relating to nuclear reactors
Inventor: ACKROYD RONALD TUNSTALL
IPC: G21C15/06
Filed: 1964-06-19
Abstract: 1,101,539. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 9 June, 1965 [19 June, 1964], No. 25457/64. Heading G6C. A fast nuclear reactor cooled by a supercritically pressurized aqueous coolant has. epithermal neutron absorber for counteracting reactivity gain on flooding concentrated in a part of the core where in normal operation the coolant density is less than elsewhere in the core. The effect of the flooding is to soften the neutron energy spectrum and as this occurs, the epithermal absorber becomes increasingly effective in capturing neutrons, being chosen to achieve peak effectiveness in advance of the 0À3 eV fission resonance of Pu 239, which is a strong contributor to the reactivity rise on flooding. Suitable absorbers are Hf, In and Eu. It is preferred that the low coolant density part of the core constitutes the core centre, an arrangement which is conveniently achieved by multi-pass coolant flow. In the reactor described, the coolant makes three passes through the core, commencing at the periphery and finishing at the centre of the core, and europium oxide is added to the fuel as a uniform dispersion in the second and third passes, the amount added being equivalent to 3% by volume of the fuel in these passes. The fuel is assembled in plate form and comprises a cermet of the mixed dioxides of U and Pu dispersed in a matrix of stainless steel, the proportions by volume being 40% mixed oxides and 60% stainless steel and the mixed oxides representing an enrichment (i.e. ratio of Pu to Pu and U atoms) of 70%. The epithermal absorber is preferably concentrated exclusively in the low coolant density part of the core since the increase in density on flooding is greater here than the average over the core as a whole and the effect of the absorber is therefore more sharp on flooding. To provide top and bottom axial reflectors, as well as the interconnection of the coolant passes, the casings of the fuel assemblies are extended at the top by hollow conical spikes and at the bottom by hollow cylindrical, conical tipped spikes. The top spikes are seated in apertures of a removable block. The bottom spikes are provided with slots in their cylindrical portions, those of the outermost row of fuel assemblies opening into a radial reflector space encircling the core and those of the other fuel assemblies opening into vertical tubes within the core support structure. The comparatively thick coolant reflector layers bounding the core on all sides provide for such a large measure of leakage control that at zero coolant density, i.e. complete loss of coolant, there is considerable loss of reactivity.

Title: Improvements in or relating to shutter mechanism for photographic apparatus
IPC: G03B9/08
Filed: 1928-09-05
Abstract: 312,877. Hart, S., and Stealey, J. I. Sept.. 5, 1928. Shutters with sliding plates, and with pivoting or rotating blades or discs.- Shutter mechanism comprises a shutter member or members, spring or otherwise influenced to tend to assume the closed position, and a solenoid coil with a soft iron armature. The energizing of the solenoid coil magnetically attaches the shutter to the armature and moves it to cause the opening of the lens aperture. Subsequently the shutter is automatically separated from the armature and returns to the closed position. In the form shown, a sliding plate 14 having a stem 15 with a piece of soft iron 18 at its upper end closes the aperture 12. The energizing of the solenoid (not shown) lifts the armature 20 together with the plate 14 until the latter, striking the stops 19, is separated from the armature and falls into the closed position. When the energization of the solenoid ceases, the armature falls, a rubber buffer 21 preventing jarring. Engagement between the shutter and the stops 19 may be made to break the solenoid circuit temporarily. The time of exposure may be altered by adjusting the stops 19, by providing adjustable return springs for the shutter, by suitably controlling the electrical circuit of the solenoid or by using shutter plates with apertures of differing size. The shutter proper may comprise a rotating disc or blade or a pair of plates operating through toggle lever mechanism.

Title: Method of and apparatus for making a black printer for four-colour reproduction
IPC: H04N1/60
Filed: 1953-09-16
Abstract: 740,658. Local copying by scanning. TIME, Inc. Sept. 16, 1953 [Sept. 16, 1952], No. 25626/53. Class 40 (3). In an electro-optical colour reproduction system in which colour component signals are corrected, e.g. by masking, and a normal black signal is derived from that colour-corrected signal of the three signals which differs least from the value when entering into a representation of a white area, supplementary colour component signals are also derived from said colour signals before correction and that colour component signal which differs least from its value for white is separated and used to modify the normal black signal in accordance with a function of the separated signal to give the black printer increased contrast in the high-light and shadow regions. The signals from the channels 11, 12, 13 corresponding to the blue, green and red colour components, and including amplifiers, compressors and mask modulators, are passed to a maximum signal separator 17 and via a compressor 18 to a modulator 19, amplifier 23 and rectifier 26 in the blue channel, and to similar elements in the green and red channels. The outputs of the rectifiers 26, 27, 28 are fed to D.C. amplifiers 41, 42, 43 and to glow lamps 37, 38, 39 serving to expose the yellow, magenta and cyan negatives. The maximum signal of the corrected signals appearing at the output of the rectifiers 26, 27, 28 is detected by the separator 33 and normally passed via D.C. amplifier 34 and switch 35 in its normal position to a glow lamp 36 serving to produce the negative for the black printer. In the arrangement according to the invention, the switch 35 is moved to its left-hand position and the output of the amplifier 34 is passed to a balanced modulator 66. The uncorrected signals in the blue, green and red channels are passed over leads 51, 52, 53 and potentiometers 54, 55, 56 to a maximum signal separator 57, the output of which is passed in parallel to an amplitude limiter 61 which provides an output signal reproducing the input signal up to, but not exceeding, a given amplitude, and to an amplitude selector 62 which produces no output signal until the input signal reaches a predetermined amplitude, after which -the output signal increases abruptly. The combined outputs of the circuits 61, 62 having, for example, the relationship indicated in Fig. 4, is applied via mixer 63 and delay line 65 to the modulator 66 to which the normal black signal is applied. The modified black signal is passed via amplifier 68, rectifier 69 and D.C. amplifier 71 over conductor 72 and the righthand arm of switch 35 to the glow lamp 36 controlling the black printer. U.S.A. Specification 2,605,348 is referred to.

[Class 100 (iv)] [See also Group XL] Pneumatic actions.-A typewriter is operated pneumatically under the control of electric signals of the start-stop five-impulse type. The armature 9, Fig. 2, of the receiving line magnet is located in a compressed-air chamber 12 and, on receipt of the no-current start signal, admits air through groove 15 and a channel 19, Fig. 3, and pipe 20 to a starting- piston 23 which at 52 unlatches the shaft 17 and permits it to be driven for one revolution through the friction clutch 55. The shaft 17 carries with it the block 18 and so enables the channel 19 to connect the groove 25, Fig. 2, with the pipes 1.. 5 for registering the signal combination. Pressure is admitted to the groove 25, or not, according to the position of the armature 9 as determined by the received impulses. Each pressure impulse is passed on through one of five pipes 26 to one of five pistons 1<1>, Fig. 4, and when a piston has been operated it is held on by pressure admitted from pipe 33 to pipe 43 through a valve 44 controlled by a cam 50.
