Title: Improvements in or relating to fuze setting apparatus for shells
IPC: F42C17/00
Filed: 1938-12-13
Abstract: 522,407. Setting projectile fuzes. RUAU, F. F., and MOLINS MACHINE CO., Ltd. Dec 13, 1938, No. 36346. [Class 9 (i) ] Apparatus for setting projectile fuzes of the kind embodying a fixed and a movable ring,  comprises a plurality of setting devices and  projectile supports  aligned therewith movable in succession in an  endless path along  which there is a loading position and a discharging position, and wherein the fuze-setting devices are operable to set the fuzes at a rest position or at a plurality of such positions along the path. A carrier 1 and a disc 4 having four projectile-supporting indentations 3 are mounted on a rotatable shaft 2 which is inclined so that the weight of the projectiles tends to retain them in position relatively  to their' fuze-setting devices. At the changing position, a projectile is deposited on a support 3 and pushed into the carrier so as to rest on a spring cushioning device 6, 60 in operative position relatively to the fuze - setting mechanism aligned with that particular support. The carrier is then' rotated through 90 degrees, and at this second station the projectile is manually rotated until a spring-pressed pawl'or plunger 5 engages within a notch formed in the fixed ring. The carrier is rotated through a further 90 degrees and during this rotation a fixed cam 10 moves axially a spur gear 9 and a second pawl or plunger 8, so that this pawl engages within a notch formed in the movable ring. The gear 9 meshes with a sun gear 11 secured to a shaft 12 so that on rotation of a handle 13 between positions determined by a fixed stop and an adjustable stop 14, the movable ring is turned by the required amount to set the fuze. The projectile is then removed. Unless a projectile has been loaded into the apparatus at the loading position, and the projectile at the discharging position has been removed, rotation of the carrier is prevented by the engagement of a lever 19 with stops 20, 21 respectively. If the fuzes are not in the "safe" position when loaded, the stop 14 may be rendered temporarily inoperative so that the handle 13 can be rotated until the pawl '8 engages the notch.

Abstract: 1,143,739. Automatic exposure control. KOPARU K.K. Aug. 15, 1966 [Nov. 6, 1965; May 27, 1966; July 13, 1966; July 14, 1966], No. 36401/66. Headings G2A and G3R. In a system for automatically controlling light intensity, a photo-resistor is included in a bridge circuit the output of which controls PNP and NPN transistors energizing a moving coil mechanism adjusting a diaphragm which determines the amount of light falling on the photo-resistor, and an e. m.f. induced in an auxiliary winding of the moving coil mechanism, during movement, is applied in opposition to the output of the bridge circuit. As applied to automatic control of the exposure of a photographic camera, light from the camera lens passes through an adjustable diaphragm 27, Fig. 1, and is deflected by a half mirror (not shown) on to a photo-resistor 1. Variations in light intensity from a desired value upsets the balance of a bridge circuit in which the photo-resistor is connected so that one or other of transistors 8, 9 is rendered conductive according to the sense of variation. The state of further transistors then changes so that an armature winding L 1  is energized in such a sense that its movement relative to a permanent magnet 25 causes appropriate adjustment of diaphragm 27. An e. m.f. induced in a second armature winding L 2  by movement of the armature applies rate feedback in opposition to the output of the bridge circuit to improve stability, and capacity such as 23 is provided to eliminate high frequency components of current in winding L 1 . Thermistors such as 12 are provided to compensate for temperature variations and to increase sensitivity of the system when the deviation is small. A suitable pin and slot lever coupling between armature 26 and diaphragm 27 is described.

Title: Improvements in or relating to flat knitting machines
IPC: D04B7/04
Filed: 1960-10-24
Abstract: 934,883. Knitting machines. R. STOLL, E. STOLL, H. STOLL, G. STOLL, and E. STOLL, [trading as H. STOLL & CO.]. Oct. 24, 1960 [Oct. 23, 1959], No. 36485/60. Class 74 (2). A flat knitting machine has main needle beds 1, 2, Fig. 1, in inverted V-formation and at least one pair of auxiliary needle beds 3, 4 in opposite V-formation. The beds 1, 2 have stitchforming and transfer needles of the latch-less type with a main hooked shank 9 and a relatively slidable outer sheath 12, the latter serving both for closing the hook of shank 9 for casting off a stitch and as a transfer point. The auxiliary beds 3, 4 are provided with from three to six receiver elements 15 and are adapted to be racked in known fashion relatively to the main needle beds to enable a narrowing operation to be carried out. The shank of each needle 9 is provided with guide grooves 10, 11 in which slide ribs on both the sheaths 12 and the opposing elements 15. In operation, needles 9 and elements 15 are advanced as in Fig. 6 and a stitch M is raised along the ramp S on to the outer edge R of the needle 9 directly above a stitch receiving notch 18 of the element 15. The needle 9, sheath 12 and element 15 are then moved down together, the stitch M passing off the edge R of needle 9 on to the outer surface of element 15. The needle 9 is then withdrawn by a slider 20 mounted in the intermediate element 15 and the element 15 is also withdrawn to allow the stitch M to drop into the notch 18. The rocking of the auxiliary bed 3 or 4 is then performed to the extent required and as in Fig. 8 the appropriate needle 9 is advanced and lifts the stitch M from the notch 18 by its ramp S. The element 15 then returns to its original position as in Fig. 1 and needle 9 is also retracted, the stitch sliding back into the hook. For stitch transference from the needles of one main bed to the other each stitch M is lifted on to its sheath 12 as in Fig. 9 and the needle of the other bed is advanced and receives the stitch on retraction of the said sheath.

Abstract: 1,119,151. Radar. ELTRO G.m.b.H. 24 Oct., 1960 [23 Oct., 1959], No. 36505/60. Heading H4D. An object, of dielectric material, located beneath the ground surface, is detected by the reflection of radio waves, the reflection occurring due to the dielectric discontinuity at the junction of the object and ground. The receiving and transmitting aerials are mounted together and moved simultaneously over the ground surface. The receiving aerials are in two sections, one of which receives reflections from the buried object before the other, hence generating an unbalanced indicating signal. The ground surface, being homogeneous, produces equal reflections in both receiving antennae which are balanced out.

Title: Nuclear fuel elements
IPC: G21C3/04
Filed: 1964-09-07
Abstract: 1,083,992. Fuel elements. NUKEM NUKLEAR - CHEMIE UND - METALLURGIE G.m.b.H. Sept. 7, 1964 [Sept. 5, 1963 (2); Sept. 13, 1963], No. 36524/64. Heading G6C. A spherical nuclear fuel element comprises fuel material applied to the wall of a cavity in a graphite sphere, the remainder of the cavity being filled with a neutron moderating material resistant to high temperatures, preferably graphite. The cavity may be spherical or cylindrical. The fuel, in the form of particles provided with coatings impermeable to gases, is applied in concentrated form with a suitable binder, for example by slip casting, to the inner wall of the sphere. As binder, there may be employed a dissolved synthetic resin, e.g. a phenol resin, which when subsequently heated after evaporation of the solvent, is polymerized and then converted into coke by cracking. A liquid binder such as furfuryl alcohol which is directly polymerized and cracked may be used instead. Since the carbonized binder is a fairly poor conductor of heat, a graphite powder is included as filler. In the finished fuel element, the fuel particles represent 5 to 50% by vol. of the fuel-containing layer. The remainder of the cavity is then filled, preferably with graphite powder, under a low compressive pressure so as not to damage the fuel particles. After the cavity has been filled, a plug is screwed into a bore in the sphere. The plug is expediently cemented in position and by heating the sphere to 1000‹ to 2000‹ C., the binder in the fuelcontaining layer and the cement on the plug are carbonized. The head of the plug is advantageously frusto-conical. In orderto increase the impact resistance of the fuel element, the wall of the sphere is thickened on the side on which the plug is situated, either by forming a spherical cavity eccentrically in the sphere or by flattening a concentrically formed spherical cavity on the appropriate side. An alternative method of applying the fuel material is possible when the cavity is of cylindrical form, the sphere being rotated and the fuel particles, in admixture with graphite powder, uniformly distributed over the periphery of the cylinder and held in place by centrifugal force, the remainder of the cavity then being filled with graphite powder while rotation is continued and the powder compacted with a suitable compacting tool.

Abstract: 1,125,481. Electro-physical measurement. NEWPORT INSTRUMENTS Ltd. Sept. 3, 1965 [Sept. 7, 1964], No, 36550/64. Heading G1N. In apparatus utilizing nuclear magnetic resonance to measure the moisture content of e.g. tobacco, a known reference sample and a test sample are tested sequentially and the response due to the known sample is used as a reference to calibrate the apparatus. The two samples A and B, are subjected simultaneously to a high frequency field derived from oscillator and resonance detector 26, and a varying unidirectional field consisting of a standing bias from battery 18 and a triangular sweep current from sweep generator 23. The standing bias on the reference sample is adjusted to a different level from that on the test sample so that nuclear resonance occurs at a different point in the sweep cycle. Both sets of resonance response pulses from the detector 26 are passed through a common high gain amplifier 28 and meter amplifier 30, the overall gain being adjustable by a potential divider 29. The two sets of amplified pulses are passed to separate meters 35, 39 by gating relays 36, 40 energized by the sweep generator 23 through adjustable time-delay circuits 41. The gain of the amplifier is thenadjusted manually or automatically, Fig. 9 (not shown), to bring the reading on meter 35 due to the moisture content of the reference sample to a given datum value, the value of the test sample can then be read directly off meter 39 which is suitably scaled. In a modification, Fig. 10 (not shown), both samples lie within a common magnet system and an auxiliary D.C. bias winding is placed adjacent the reference sample.

Abstract: 1535876 Shearing; punching SOCIETE DES ANCIENS ATELIERS H JAMBON 7 Sept 1976 [10 Sept 1975] 37090/76 Heading B3W In an hydraulic shearing or punching press, a fluid accumulator A.C. communicates with the working side of the piston 1, via a circuit including a normally-closed spring loaded valve 10 and a spool valve 13 movable in a chamber 12, transversely to the piston axis, and a rod 19 rigid with the piston 1 slides along a link 18 which has an adjustable nut 21 at the end approached when the piston is ending its working stroke, a bellcrank 17 pivotable about a fixed pin and having one arm connected to the other end of the link 18, having the other arm in engagement with an extension of the spool valve 13. In operation, a motor M drives pumps P 1 , for directing hydraulic fluid alternatively against the working and return surfaces 3, 4 respectively of the piston 1 via a solenoid valve EVA, and a pump P 2  for filling the accumulator AC. Fluid from the working chamber 5 is directed by a valve 7 to a reservoir 25 during the piston return stroke. When a pressure switch 9 detects that the accumulator AC has reached the predetermined pressure, the pump P 2  is connected via a solenoid valve EVB to the reservoir 25 under zero pressure to cool the hydraulic fluid. From the begining of a working stroke, fluid is supplied to working surface 3 only via the pump P 1  and valve 7 until the arm 19 engages a switch 20 which via a solenoid valve EVC opens the valve 10 to connect the accumulator to the working chamber 5. Engagement of the arm with the nut 21, adjusted for the required working stroke length, moves one spool valve 13 to the right to close the port 14 from the accumulator and open the port 15 to the reservoir. Actuation of a switch 24 during this movement reverses the solenoid valves EVA &c. and initiates the return stroke of the piston.

Abstract: 856,133. Pottery moulding apparatus. HOMER LAUGHLIN CHINA CO. Dec. 11, 1956 [Dec. 12, 1955], No. 37814/58. Class 87(2). A machine for charging clay into moulds in a dinnerware making apparatus comprises travelling annular cutters moving in an endless path above a belt carrying a blank of clay for cutting slugs from the block and depositing them in moulds. Moulds carried by an endless chain A, Fig. 1, are charged with clay at a station G, carried thence to a jigger C, and thence back and forth in a drying chamber E to a station F where the pottery is stripped from the moulds. Clay is fed by screws from a hopper 11 through conduits 12, 13 to a nozzle 14, Fig. 2, from which it emerges as a ribbon 15 on to a travelling belt 21, to be cut by a mechanism 22 into square blanks 23. The belt 21 travels at a rate relatively to the ribbon 15 such that the blanks 23 are spaced at distances equal to the spacings of the moulds on the conveyer chain A. Each cutter 26 depends from a cylinder 27, and when a circular slug is cut a valve 56 is opened automatically to connect the cylinder 27 with a suction pipe (not shown). The slug 34, Fig. 4, is thus held in the cutter 26 and is carried thereby to the opposite side of the charging apparatus, where the cutter descends into a mould 6, Fig. 4, and the valve 56 is again opened to connect the cylinder 27 with an air pressure pipe (not shown). A piston 33 within the cylinder 27 is then forced down to actuate an ejector 31 slidable on a pin 29 to discharge the slug into the mould. Some air passes through a hole 35 in the piston 33 and through passages 30 to ensure separation of the slug from the ejector and pin. The jigger C is described in Specification 856,135, and the machine for stripping the ware from the moulds at the station F is described in Specification 856,134. U.S.A. Specification 2,555,227 also is referred to.
