Title: Method of and means for filling smoking tobacco or the like in boxes or other packings
IPC: B65B1/04
Filed: 1924-05-05
Abstract: 215,389. Aktiebolaget Formator. May 4,1923, [Convention date]. Packing tobacco &c. into boxes &c. - In a machine for packing tobacco &c. into boxes &c., the tobacco is fed from a hopper 1, Fig. 1, to a funnel 2. A horizontal rotary table 21, Figs. 1 and 2, with pockets I, II - - &c. having an outline corresponding to that of the boxes to be filled, rotates intermittently to bring the pockets beneath the funnel 2. The pocket is filled from the funnel, a cutter 3 being pressed by springs so as to separate the charge from the source of supply when the pocket moves away. At a subsequent position of rest, grippers 22 move a cover paper from a pile 19 beneath a plunger 17 which presses it into a pocket above a charge of tobacco. A box is fed by chain carriers to a support 12, Fig. 5, which rises, and in conjunction with grippers 13, holds the box in position beneath a nozzle 10, through which the tobacco and cover paper are thrust by a plunger 6. The box support falls and the filled box is fed away.

Title: Nuclear fuel assembly
Inventor: DELAFOSSE JACQUES
IPC: G21C3/332
Filed: 1971-04-23
Abstract: 1,274,405. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 23 April, 1971 [6 May, 1970], No. 11125/71. Heading G6C. A nuclear fuel assembly comprises a cluster of fuel rods 12, retained parallel and at the nodel points of a regular network by a bottom end plate 14 which bears the fuel rods 12 and by spacing grids 20, the bottom end plate 14 being connected to a top end plate (not shown) by tierods 18 which occupy certain of the nodel points of the network, where they are substituted for the fuel rods, and which are of a diameter substantially equal to that of the fuel rods, the grids 20 frictionally engaging both the fuel rods 12 and the tie-rods 18. Each of the grids 20 comprises inside a frame a network of nested metal sheets bounding cells of square section. The metal sheets have portions cut out and each is formed by two parallel rectilinear ribbons connected by narrow corrugated strips 30. The tie-rods 18 may be formed as guide tubes for neutron-absorbing control rods, or may contain a burnable poison or some other filling material. The bottom of each of the tierods 18 has an attaching stud 32 screw-threaded to receive a securing nut 34. Where the tie-rod is a control rod guide tube, the stud 32 is formed with an axial passage through which coolant flows. The top of each of the tie-rods 18 is attached to the top plate (not shown), e.g. by crimping. The top and bottom plates are formed with orifices through which coolant enters and leaves. The movement of the grids 20 along the tie-rods 18 is limited by tubular struts, such as 36, 38 and 40, borne by the four corner tie-rods 18. The total length of the struts and the grids 20 is less than the distance separating the facing surfaces of the top and bottom end plates, so as to leave the necessary clearance for total differential elongation during operation. Since the number of fuel rods 12 is much greater than the number of tie-rods 18, the frictional forces exerted by the grids on the assembly of fuel rods are much greater than those exerted on the assembly of tie-rods. As a result, such forces retain the grids on the fuel rods, while the tierods slide slightly when thermal conditions change. However, movements of low amplitude can take place between the grids and some of the fuel rods, due to differences in expansion which may occur amongst the fuel rods.

Title: Improvements in or relating to the remote control of electric generators or other current supply means for arc welding
IPC: B23K9/10
Filed: 1944-06-12
Abstract: 603,705. Control systems for welding arcs. RIMMINGTON, F. June 12, 1944, Nos. 11173/44, 13563/44, 18204/44, 1881/45 and 8512/45. Drawings to Specification. [Class 38 (iv)] Relates to a remote control system for the generator or other current source for a welding arc as described in Specification 562,131, wherein the operator temporarily varies the arc length to actuate voltage sensitive relays shunted across the arc to control a motordriven current controller, and consists in circuit arrangements which avoid the use, for control purposes, of the voltage in the welding circuit when'the electrode is " scribbled " on the work, this voltage having been found, in some cases, to vary considerably with the length of the electrode and to cause erratic control. In all of the several arrangements described the control voltages are obtained either by the operator drawing a long arc, breaking the arc, or short-circuiting the work and electrode (or its holder), whilst time delay means are provided for causing adjustment of the current controller to start only at a predetermined time after the arc voltage has been changed from the normal welding value. In one arrangement the motor is started up in one direction by the operator drawing a long arc for a certain time and in the other direction by drawing the arc for a longer period, the motor being stopped in both cases by breaking the arc, after which welding can proceed at the adjusted current value. Before breaking the arc the operator can observe the effects of his adjustment by returning to a normal arc length. In another arrangement, adjustment is effected in one direction by drawing out the arc and in the other by pressing the electrode or its holder on to the work, whilst in further arrangements current is lowered by shorting the work and electrode for a certain time and is increased by making a momentary short circuit, followed by a longer one. In all arrangements a clutch electrically operated by the motor current, may be inserted in the drive between the current controller and its motor to allow manual adjustment of the controller when the motor is at rest. An adjustable resistance, or a self-regulating one made from the material known under the Registered Trade Mark " Metrosil," may be included in the control circuit to compensate for changes of voltage in the control circuit due to different lengths of cable being connected in the welding circuit.

As shown in Fig. 2, the toothed wheel i meshes a gear i secured to a jack shaft having connecting rods k<SP>1</SP>, k<SP>2</SP> to drive the railcar wheels, but in modifications the toothed wheel may be replaced by a chain sprocket or bevel wheel meshing directly or indirectly with the output gears. As shown in Fig. 5, two prime movers drive the bevel pinion f through input shafts a<SP>3</SP>, a<SP>4</SP> and the gear i drives the output gear through intermediate gears m, m<SP>1</SP>, the gears m, m<SP>1</SP>, j being rotatably mounted in a separate case l, pivotable about the cross-shaft g' to allow arcuate motion of the output shaft j<SP>1</SP>. The main casing of the gear may be made to slide backwards and forwards at the same time, thus allowing vertical movement of the shaft j' in the usual horn blocks. In one modification, Figs. 6, 7 (not shown), two similar trains of gears are shown transmitting drive to two railcar driving axles, and in another modification, Fig. 8 (also not shown), bevel gears on each side of the gear mesh bevel gears on the end of cardan shafts containing two flexible couplings and driving railcar axles through further bevel gear pairs, one of these gear pairs being shown as of the hypoid type so that the cardan shaft can be extended to drive still further axles. The change speed gear can alternatively drive the input bevel gear f through a freewheel, to prevent braking of the railcar by the engine, and the control for the positive clutch means g<SP>4</SP>, g<SP>5</SP> may be interconnected with the control for the change speed gear in such a way that the operation of the former is prevented, save only when the latter is partially or wholly disengaged.

Title: Improvements in and relating to the preparation of silicic acid
IPC: C01B33/32
Filed: 1965-03-18
Abstract: Finely divided silicic acid is prepared from an alkali metal silicate solution with a molar ratio SiO2:M2O (where M is alkali) in the range 2.5:1 to 4.5:1 and a maximum concentration increasing with the above ratios but below 165 g. of SiO2 per litre, by heating said solution to over 100 DEG  C. under pressure and separating ppted. silicic acid from the alkali metal silicate solution of reduced SiO2 content.  The preferred concn. of SiO2 is 10-125 g./litre and the preferred temperature of reaction is 130-200 DEG  C.  Solid alkali metal silicate may be added to the resulting silicate solution to produce a fresh starting solution.  The SiO2:M2O ratio may be lowered by adding MOH solution.  The process may be carried out in a continuous manner, e.g. in an externally heated flow-tube, or in a multi-stage manner. The process may be used for purifying alkali metal silicate solutions since impurities, e.g. Fe, Al and Ti ions, are ppted. from the solution with the silicic acid.

Abstract: 569,621. Money-delivering apparatus. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and DIXON, S. M. July 15, 1943, No. 11534. [Class 27] In apparatus of the kind in which -coins 2. are stored in a tubular container 1 and the lowermost coin is ejected when required by means of an ejector 6 moving transversely across the axis of the column and engaging the edge of this coin, the base 4 of the container is provided with one or more fixed ramps 8 adapted to support the lowermost coin with its edge adjacent the ejector at a corresponding distance above the base 4, the ejector being arranged to pass between or at the side of the ramp or ramps during its ejecting movement. Thus, it is immaterial whether the lowermost coin is flat or bent ; in all cases its edge next the ejector is at the same height from the base and is properly engaged by the ejector. In the construction shown in Figs. 1 and 2, the container 1, which may be vertical, is inclined at 45 degrees and the lowermost coin is bent and has its convex side uppermost, its edge next the ejector 6 resting on a pair of ramps 8 between which the ejector moves in a groove 7. If the coin is flat or if it is bent with the concave side uppermost, its edge next the ejector is supported by the ramps 8 at the same height in each case. The ejector may move in one direction only or may reciprocate, in the latter case the tail part 13 is sufficiently long to support the next lowermost coin 11 until the ejector has completed its return stroke. In the modification shown in Fig. 5, a similar pair of ramps 14 are provided diametrically opposite the ramps 8, so that both the forward and rear edges of the lowermost coin are supported by the ramps. Pins projecting from the base 4 may be.used instead of the ramps 14.
