Title: Device for filing and binding papers
IPC: B42F13/12
Filed: 1920-11-18
Abstract: 171,306. White, L. D. Nov. 18, 1920. Spiked-prong and like perforators; post files.- Papers are filed and bound upon staples, rails, &c., which are temporarily clamped in an upright position on the frame of the apparatus, rods forming the back of the frame having a pressurebar sliding upon them for forcing the papers down the nails &c. As shown, a clamping-bar N is held to the hollow base B by thumb-screws 0 and is slotted at P to receive one or more nails &c. Q. A pressure-bar D, having apertures F through which the nails can freely pass, slides upon rods C forming the back cf the frame, and is guided through the frame member A by rods G, a spring I being positioned on the guide-rods between the frame member A and an operating- handle J joining the rods. Adjustable projections S serve to align the papers sideways, and projections L<1>, Fig. 1, or K, Fig. 2, prevent the papers from curling up and thus forcing the spikes forward. A removable slotted plate may be placed between the pressure-bar and clamping-bar to keep the spikes in alignment. The rods G and handle member J may be omitted and the device operated by projections on the pressure-bar, the spring in this case being around the rods C. The clamping-bar N may be removable with the spikes &c. and clamped to the under-side of the hollow base, or it may be in sections with the spikes between. In a modified form of apparatus, designed for use with a single spike, the latter passes into a hollow guide-rod forming part of the pressure-bar, the back of the frame engaging slots in the pressure-bar. The papers filed may be permanently bound, for example, by binding the ends of the spikes down, by pressing washers on the ends of the spikes, or by means of threaded twine; or two sections may be inverted and the nails driven into the opposite section.

Filed: 1966-07-20
Abstract: 1,149,946. Cooling reactors. EUROPEAN ATOMIC ENERGY COMMUNITY. 20 July, 1966 [23 Aug., 1965; 20 Sept., 1965], No. 32673/66. Heading G6C. In a fast breeder reactor, the fluid coolant is circulated by means of capillary action and vaporization. The liquid coolant is applied to one end of each fuel rod and is moved longitudinally along the rod outer surface by capillary forces until vaporized. Condensation of the vapour occurs at the inner surface of the reactor vessel, on a capillary lining which returns the liquid to the end of the fuel rods. In one embodiment, the heat is removed from the reactor vessel by a coolant gas while a second arrangement employs thermionic converters. The coolant liquids used may be either lithium or lead. In the thermionic arrangement, which is suitable for a space vehicle, the reactor core is divided into equal halves, the liquid coolant enters the central zone of the core, at the division, and is then moved outwards, from the centre, by capillary action. The capillary surface surrounding each fuel rod may be either a grooved pipe or a porous layer of metal sponge. The reflector and control rods may also be provided with capillary coolant structures.

Title: Pulse counting apparatus
IPC: H03K23/82
Filed: 1952-12-24
Abstract: 729,172. Electronic counting apparatus. WESTERN ELECTRIC CO., Inc. Dec. 24, 1952 [Dec. 27, 1951], No. 32755/52. Class 106(1). A pulse counter comprises a plurality of twostate stages, at least one stage being adapted to alter the state of its succeeding stage upon alternate changes of its own state, a first means adapted to connect a source of pulses to be counted to any preselected one of the stages, a second means adapted to connect the source of electric pulses to a different preselected one of the stages, and means including one of the stages adapted to control the operation of both the first and the second means. In the described embodiment a plurality of trigger pairs of the type described in Specification 148,582, [Class 40 (iv)], are connected to form a binary counting chain, but instead of the negative input pulses being applied always to both sides of the first trigger pair T1, T2 in the usual way, varistor gating arrangements V1, V2 are biased by D.C. connections to the anodes of the valves so that the input pulse is directed to the grid of the conducting valve only. A similar varistor gate V3, V4, controlled by a trigger pair T7, T8 in another section of the counter, allows the input pulses to pass varistor V3 until the stage T7, T8 is reversed when the resulting change in bias causes subsequent pulses to pass varistor V4 only and enter the counting chain via capacitor C7. This causes the chain of four trigger pairs to complete a cycle with ten input pulses. Other arrangements of gates will provide a counter to any desired base of notation; a general formula for any base of notation is described in the Specification.

Class 27 The vending machine of the parent Specification, in which several articles can be selected for delivery by conveyer belts after establishing sufficient credit, is modified by the provision of a unit having vertical shoots 8 and delivery drawers 10 for the sale of fast-selling flat articles, the unit either .being incorporated with the main machine or arranged separately and connected by cable to the coin-operated credit-registering and checking arrangements of the main machine. The initial movement of a drawer 10, Fig. 3, withdraws a pin 24 from a switch'23, which then closes to signal the selection of a particular article and to initiate a creditchecking operation. If the credit is sufficient, a solenoid 18 withdraws a pin 17 to allow the drawer to be fully opened and the article, no longer supported by a platform 14, falls into the open rear end 12 of the drawer. On return movement of the drawer, the article falls into a delivery shoot 11 and a credit-reducing cycle and reinitiates a credit-reducing cycle and restores the circuits for the next selection. At the. same time, the pin 24 opens the switch 23 and the solenoid 18 releases pin 17 to lock the drawer again. The switch 25 may alternatively be fitted above the drawer for operation by the stop 16 when the drawer is fully opened. Instead of being operated by the initial movement of the drawer, the switch 23 may be operated by movement of the handle 15 relative to the drawer, either by means of links 32, Fig. 7, pivoted to the drawer so that the handle must be lifted over a ledge 34 or by means of links with a pin-and-slot connection to the drawer. "Empty indicators may be provided.

Title: Improvements in or relating to the treatment of cellulosic textile fabrics
IPC: D06M11/40
Filed: 1966-07-26
Abstract: 1,142,385. Mercerizing cellulosic fabrics. C. DUCKWORTH. 24 July, 1967 [26 July, 1966], No. 33470/66. Headings D1L and DIP. In the stenter chain mercerising of cellulosic fabrics, e.g. cotton fabric, the fabric is washed before it enters the stenter chain to reduce the concentration of the swelling agent, e.g. caustic soda, impregnated into the fabric at the saturation stage to a level of not less than 20‹ TW. Cotton fabric may be impregnated with caustic soda of 50‹TW-60‹TW for not less than 45 secs., washed by passage through a wash box without width stretching so that when it enters upon the stenter chain washing stage it contains approximately 25‹TW and is then washed to reduce the strength from 25‹TW to less than 10‹TW whilst maintaining tension on the stenter chain. Apparatus for carrying out the process may comprise a three bowl saturation and squeezing means, appropriate timing drums and a clip stenter chain equipped with weir and suction wash units and having in front of the stenter chain a light load draw nip and arranged after the stenter chain wash boxes for final washing acidification and washing, a wash box being arranged after the timing drums and immediately before the draw nip. The wash box may be divided into four internal compartments to allow counter-current or co-current flow of the wash water and may be provided with a pump so that wash water recirculation may be carried out in any number of the wash-box compartments. The wash box may be provided with rollers to provide the fabric with a serpentine path with repeated dips and a final squeezing before passing to the stenter. Intermediate nips or squeezes may be provided between dips and the fabric may be in close contact with the surfaces of the upper and lower rollers immersed in the washing liquor so that the fabric does not disengage from the roller surfaces, during its repeated dips and squeezes. Alternatively the washer may be a system of weir/suction units or spray/suction units. If the system of repeated dips and squeezes in the washer is allied to low volume co-current wash liquor flow the fabric just prior to stenter washing has a negligible gradient of concentration of caustic measured through the thickness of the fabric and the resulting fabric has the same visual appearance of a fabric mercerised under similar conditions but without the wash, but if a washer without intermediate dips and squeezes and with a high wash liquor flow in the countercurrent direction is used although the concentration of caustic soda in the fabric as ascertained by titration is not below a minimum of 20‹TW, the gradient of concentration within the thickness of the fabric shows a wide variation, that on the surface being as low at 7‹TW and that in the centre as high as 40‹TW so that the fabric shows a different type of lustre or sparkle.

Abstract: 846,568. Abrasive wheels. MINNESOTA MINING & MANUFACTURING CO. Nov. 6, 1956 [Nov. 7, 1955], No. 33852/56. Class 60. An abrasive wheel comprises an annulus of juxtaposed radially-extending flap sections 10 of abrasive sheet material rigidly bonded together over an area 11 extending across their entire width for at least “ inch radially outward from the inner end of each section so as to form a rigidly reinforced inner vein in the annulus. The flap sections, which may consist of a drill cloth backing sheet having an abrasive coating stuck thereon by cured phenol-aldehyde bond and sandsize adhesive coatings, are die-cut with notches 12, 12a, 13, 13a having rounded corners to reduce stress concentrations due to centrifugal force. The annular structure is built up by first pressing the flap sections together in a U-section support and adhesive is applied to unite the flap sections over the area 11. After removal from the support, the structure is formed into an annular shape and further adhesive applied. Suitable adhesives are cured epoxide, polyester, alkyd or phenolic resins. The notches 12, 12a, 13, 13a form grooves 14, 14a, 15, 15a which receive rings 18, 18a, 19, 19a on flanges 17, 17a. A cylindrical hub 16 is fitted between the flanges and the whole clamped between nuts 23, 23a on a shaft 22, in which is a sleeve 21. More or fewer than two grooves may be provided ; if no grooves are used, reinforcing washers of high tensile strength such as glass-reinforced plastic or metal may take the place of the flanges, 17, 17a and are stuck to the lateral surface of the wheel with a high shear strength adhesive. More than one wheel may be mounted on a single shaft. The wheel may be carried by a counterweighted pivoted lever so that it operates in succession on a series of workpieces on a travelling conveyer passing beneath the wheel. The speed of rotation of the wheel is in excess of the critical speed at which shreds or threads of the flap section are seen to be emitted.
