Title: Improvements in or relating to nuclear reactors
IPC: G21C5/16
Filed: 1960-08-16
Abstract: 965,533. Moderator structures. BABCOCK & WILCOX Ltd. (Deutsche Babcock & Wilcox Dampfkesselwerke A.G.) Aug. 16, 1960, No. 28358/60. Heading G6C. The care of a nuclear reactor comprises a cylindrical assembly of blocks of moderator material, e.g. graphite, having plane side faces parallel to the axis of the assembly, the plane side faces of laterally adjacent blocks being in contact and their corners adjacent, which assembly is supported with its axis horizontal by a supporting cradle or framework 9, the corners of blocks projecting towards corners of adjacent blocks being chamfered (Figs. 2 and 3, not shown) and the blocks so oriented and supported that downward forces on them due to gravity and also to restraining means 13 extending around the upper periphery of the assembly tend to ensure the maintenance of contact between the block plane side faces. The blocks of the assembly comprise square-section blocks 2, those in the centre being pierced by fuel channels 4, surmounted by reflector blocks 12 shaped so that the upper surface of the assembly is cylindrically curved. Some of the square-section blocks 2 of the lower part of the reflector rest directly on supporting surfaces of the cradle or framework 9, which also has recesses 11 housing rectangular-section blocks 10 included in the lower part of the reflector. The restraining means are of any suitable construction and, as shown, comprise a plurality of chains spaced along the length of the block assembly so as to brace each of a number of block layers transverse to the assembly axis, the end links of each chain being secured by securing means 14 to the respective sides of the cradle or framework 9. The securing means 14 may be constructed as eccentric devices through the rotation of which the tension in the chains may be adjusted, or that by the action of springs or torsion rods on the eccentric devices the tension in the chains may be regulated during expansions and contractions of the assembly. Specification 965, 535 is referred to.

Title: Improvements in wrapping machines
IPC: B65B25/16
Filed: 1933-10-13
Abstract: 411,730. Wrapping-machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London- (Aktiebolaget Akerlund & Rausing ; 29, Kungsgatan, Stockholm.) Oct. 13, 1933, No. 28365. [Class 94 (i).] A machine for wrapping loaves and similar articles is mounted on a table 1, Figs. 1 and 6, and comprises a holder 3 for waxed wrappers, which are taken in turn by hand and placed over an opening 4, with one edge inserted under a clamp 5. The size of the opening can be varied by means of adjustable ends 7, to conform to loaves of different lengths. The height of the table 3 above the machine bed can be adjusted by means of screw supports 8, in sleeves 9, and adapted to be moved by nuts 10. A loaf a, Fig. 2, is placed upside down on the wrapper b, just over the opening, through which it is thrust with the wrapper. This folds the wrapper up round the loaf. A crosspiece 52 with a folding plate 53 is now moved to the right, Fig. 6, and forms the fold c, Fig. 4, and the operator turns down the folds d by an inward movement of the hands. A crosspiece 22 with uprights 56, 57 moves the packet to the right beneath a yielding member 15, which turns down the flap e upon the top of the loaf, the wrapper being released from the clamp by the movement of the packet. A heated plate 14 causes the over-lap to be sealed, adhesion being secured by means of yielding plates 12. The movements of the parts are derived from a driven shaft 31, on which is mounted a cam 30 engaged by a roller 28 on a lever 25. The lever is connected to a crosspiece 23 sliding on guides 20, which is automatically connected and disconnected to the crossheads 21, 22 in such a manner that the crosshead 21 is first moved from the position shown in Fig. 6 until it is adjacent to the crosshead 22. It is then disconnected and the crosshead 22 moves to the right, after which both parts are moved back to the positions shown. In order to compensate for the varying thickness of loaves, the plate 53 is set a little higher than is necessary, and an adjustable inclined surface 60 is arranged to engage a depending part 52 of the plate 53 so that the latter descends on to the loaf during its forward movement. In a modified form of machine, the folds d are automatically formed by swinging blades mounted on the part 52, or by sliding pieces which turn down the ends before the side fold is made. The bed on to which the loaf is pressed may be made yielding, and the folders may be in the form of rollers.

Title: Improvements in or relating to apparatus for determining the distance between two or more stations
IPC: G01S11/16
Filed: 1933-10-13
Abstract: 411,356. Distance-measuring apparatus. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN-APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. Oct. 13, 1933, No. 28393. Convention date, Nov. 25, 1932. [Class 118 (ii).] In a system for measuring distance by the time lag between sound waves and wireless waves, the electrical current serving to feed the sound source modulates the wireless waves as soon as the acoustic transmitter is connected in circuit. As shown in Fig. 1, the motor 1 drives generator 2 which feeds the sound emitter 3 and transformer 7. When the circuit is completed by cam 5 the sound emitter is operated and current flows through transformer 7, which supplies current to the wireless transmitter 8 in rhythm with the sound signals. Fig. 2 illustrates an embodiment in which an air sound emitter 12 and an under water sound emitter 21 are operated in turn, the wireless transmitter being operated in synchronism with both emissions. Specification 372,750 is referred to.

Title: Improvements in or relating to circuit arrangements for generating sawtooth currents
IPC: H04N3/185
Filed: 1953-10-15
Abstract: 748,429. Inductors; rectifying. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. Oct. 15, 1953 [Oct. 15, 1952; Aug. 17, 1953], No. 28440/63. Class 38 (2). [Also in Group XL (c)] In a circuit of the " resonant return " type for generating a saw-tooth current in an inductance coil, and in which the coil is fed from a driver valve through a transformer from which an E.H.T. voltage is derived by rectifying voltage peaks occurring during the fly-back, the driver valve is coupled to the transformer by connecting the valve to the common point of two inductors connected in series across a portion of the transformer, at least one of the inductors being variable. Fig. 1 shows a conventional circuit comprising deflection coils 4, a damping diode 2, an H.T. boost capacitor 1 and an E.H.T. rectifier 7 modified in that the driver valve 5 is coupled to the scanning transformer 12 through coils 8 and 9. By varying the inductances of these coils together or separately it may be arranged that the sawtooth current amplitude and the E.H.T. voltage may be varied independently of each other or conjointly such that a variation of the E.H.T. voltage is effected without changing the deflection amplitude. The coils may, as in Fig. 5, have a common adjustable core and be such their total inductance remains constant, coil 8 being movable axially to vary the total inductance. Capacitances may be connected across the inductors to assist in obtaining the desired change of E.H.T. voltage (Fig. 7, not shown) and the variable inductors may comprise a fixed and a variable inductor in parallel (Fig. 6, not shown). Specification 482,370, [Group XL], is referred to.

Title: Improvements in automatic pressure regulators
IPC: G05D16/18
Filed: 1952-11-13
Abstract: 732,464. Automatic pressure control systems. GELIX, A. J. M. L. Nov. 13, 1952 [Nov. 22, 1951], No. 28631/52. Class 38 (4). In Fig. 2, air under pressure is supplied by an air pump (not shown) through an oil filter 101 and reservoir 102 to an enclosure 105 supplying a nozzle 106. A bellows 107 responsive to enclosure pressure acts in opposition to a bellows 27, responsive to a reference pressure, on a lever 16 pivoted at 17. Deviation of enclosure pressure from the reference pressure causes contacts 31, 32 to be open or closed according to the sense of deviation so that a reversible motor 12 operates in one direction or the other to adjust a variable speed gear 51 between one of two input shafts 8, 9 of a differential gear 7 and a continuously running motor 52 driving them. The output shaft 6 of the differential gear adjusts a valve 5 in the appropriate sense to maintain the pressure in the enclosure 105 equal to the reference pressure by varying the leakage to atmosphere through conduit 3. Follow-up is provided by a weight 18 moved along lever 16 upon operation of motor 12. The reference pressure is determined by a fixed weight 116 and a variable weight 118 acting on a bellows 111 associated with one end of a mercury manometer producing the pressure in bellows 27. In a modification, Fig. 1 (not shown), in which a similar control system maintains constant vacuum in an enclosure by control of the leakage from atmosphere to the enclosure, the arrangement of bellows is slightly modified and a free end of the mercury manometer may be raised or lowered by a motor to produce a predetermined variation of the reference, and hence the enclosure, pressure. The construction of bellows of small volume to reduce temperature errors is described.

Filed: 1928-10-08
Abstract: 316,473. Mayer, F. Oct. 8, 1928. Sewing-machines, driving. -Gearing is added to the shaft of an ordinary houseold sewing machine to slowup the rate of the needle for the same movements of the treadle, to adapt the machine for embroidery. In the form shown in Fig. 1, the needle is driven in the usual way by the shaft 5, pulley 1, flywheel 3 and coupling 4. To adapt the machine for embroidery, the flywheel is disconnected from the shaft by screwing out the nut 4 and a pair of rigidly connected gear wheels 6, 7 are raised by the lever 9 to mesh with gear wheels 6<1>, 7<1>. The wheel 6<1> is rigid with the pulley and the wheel 7<1> with the shaft. The pulley therefore drives the shaft through the gear wheels at a much reduced speed for the same movements of the treadle. In the form shown in Fig. 4, the gears 6 and 7 are rotatably mounted on a pin 14 on the pulley 1. The gear 6<1> can be coupled to the pulley by a handle 12 so that the whole rotates as a unit for ordinary sewing, or it can be freed, when the shaft is rotated, after unconnecting the flywheel, at a reduced speed for embroidery by the pulleys acting as sun-andplanet gears.
