Title: Improvements in or relating to tying machines
Inventor: NORSTRAND LEIF ROLAND
IPC: A61F13/15
Filed: 1964-11-02
Abstract: A device for feeding sanitary towels in string formation to loop tying and separating mechanism comprises a form of wheel 11 having four trough shaped members 18 each adapted in turn to engage a towel and draw it from a tube 23 (Fig. 1 not shown).  The tube 23 is periodically rotated in opposite directions to twist the tubular knitted fabric 24 extending between the core 25 of each towel into a cord.  Consequently when the two uppermost members 18 are so positioned the length of cord extends over two loop tying members 3 and over a cutting device 7 positioned between the loop tying members.  The wheel is mounted on a shaft which in addition to being rotated is also movable downwardly to draw the end portion about the loop forming members when they engage the cord and tie the loops whereafter the wheel is raised to effect the disengagement of the loops from the members after the cutting device has severed the cord between the loops and separated one towel from the rest.  Further rotation of the wheel delivers the separated towel and positions the following towels for loop tying and separation.  A metal strip 19 actuated by a push rod 21 from a vertical cam 22 is provided for each trough shaped member 18 and is adapted to secure each towel in turn in its trough and to release the towel after it has been separated.

Abstract: 1480898 Fibre-containing heat-insulating compositions FOSECO TRADING AG 16 Sept 1974 [28 Sept 1973 30 Nov 1973] 45500/73 and 55758/73 Heading C3N A method for the production of shapes of inorganic fibre-containing refractory heat-insulating composition comprises mixing together a granular or powdered refractory material, inorganic fibre selected at least in part from refractory oxide fibres, e.g. silica, alumina or zirconia fibres, carbon fibres and metal fibres, an amount of a foaming agent sufficient to cause the composition to foam during the mixing operation and a binding agent, forming the composition to the desired shape, causing or allowing the binding agent to set or harden, and drying the shape. Part of the inorganic fibre may be silicate fibre, e.g. calcium silicate, alumininosilicate or glass fibre. The metal fibres may be of steel, chromium, nickel, tungsten or molybdenum. The refractory material may be sand, silica flour, olivine, chamotte, alumina or any refractory silicate. The binder may be an alkali metal silicate, naturally occuring gums or resins, starch, or a synthetic resin such as a urea-formaldehyde, phenol-formaldehyde or furane resin. A precursor for a binding agent may be added at an early stage of mixing the composition and at the end of mixing an accelerator or catalyst added to convert the precursor to an effective binding agent. A small amount of water may be added to the mixture sufficient to assist the foaming agent to establish a substantial foam. Preferred foaming agents are alkyl sulphates, alkyl aryl sulphonates and napthalene sulphonates. The hardening or setting of the mixed formed composition may be accelerated by adding a catalyst for the binder or, in the case where an alkali metal silicate is used, passing an acid gas, e.g. CO 2 , SO 2 , HCl or SO 3 , therethrough. The specific example describes the production of a shape from a mixture of alumina fibre, glass fibre, urea-formaldehyde resin, water an alkyl sulphate surfactant, and an equal weight mixture of silica flour and silica sand.

Title: Hydraulic rotary motor drive
IPC: F15B9/14
Filed: 1971-10-04
Abstract: 1327895 Fluid pressure servomotor systems ROBERT BOSCH GmbH 4 Oct 1971 [16 Oct 1970] 46037/71 Heading G3P [Also in Division F2] A rotary hydraulic motor, supplied from a variable displacement pump 6 driven by a motor 15, is controlled by a pulse transmitter 1 which, via a translator 2, controls a stepping electric motor 3 which drives an input shaft 11 to a servovalve 4, which valve in turn has an input shaft 14 from the motor 7 and controls the displacement of the pump 6. This control is by means of a ram 17 which receives fluid from a pump 23, the pressure difference across the ram being determined by the valve 4. A further pump 24 is attached to the lines connecting pump 9 to motor 7 via one way valves 26 and 27, relief valves 31 and 32 also being provided, and a valve 48 which connects the lower pressure line to the reservoir 33. In operation the motor 3 rotates through a predetermined angle in response to the pulse generator 1 which causes, by way of the servo-valve 1 adjustment of the pump 6 so that the motor may rotate through a similar angle, stabilization of the control being achieved by the feedback from motor to valve 4 via shaft 14 (which also drives the load 8). Throttle valves 40 and 41, adjustable by a ram 46 connected as shown may be incorporated to damp the movement of piston 17. The electric motor 3 may be replaced by a pneumatic motor, and the pulse transmitter can be a pulse generator, forward-backward counter, a magnetic store, punched tape store, or electro-mechanical pulse transmitter. The servo valve is shown in Fig.3 and comprises a lever 54 with control surfaces 56 whose spacing from two nozzles 57, 58 controls the flow from each nozzle, to control the pressure in chambers 59 and 62 to which pressure fluid is supplied and which also have connections to the two sides of piston 17, so that the position of lever 54, determined through rotation of shaft 11 with respect to shaft 14 through a screw coupling 13, controls the pump displacement.

In order to divide off a portion of paste from the supply in the hopper, a lever 46 powered by a double-acting pneumatic jack 50 raises a carriage 38 so that a bar 55 can lift the cylinder through the housing 72 to a filling position beneath the hopper 10 as shown in Fig. 4 and a finger 56 can raise the piston 66 to a predetermined point within the cylinder to form a filling chamber thereabove. A lever 24 powered by a cylinder 29 slides the shutter-cutter 21 so that the aperture thereof is in register with the funnel outlet to allow paste to fall into the filling chamber of the cylinder 36. The delivery is assisted by connecting the cylinder 36 via a pipe 71 to a source of vacuum. A positive pressure may also be applied to the funnel 10. After the chamber is full, the shutter-cutter 21 is returned to cut the paste and seal the funnel outlet, the cylinder 36 and piston are lowered relative to one another to the rest position shown in Fig. 2 so that the portion of paste is left in the housing 72 to be swept out by the blade (74). The movement of the piston 66 relative to the cylinder 36 may be altered by manually rotating a wheel 64 to adjust the position of the finger 56 on a telescopic tube 57 which also carries the bar 55. The piston 66 cylinder 36 and blade (74) may be formed of a stearine filled polyethene to provide non-stick surfaces. Alternatively, the blade (74) may be sprayed with oil-containing compressed air. The top of the funnel 10 may have a cover (16, Fig. 1) which is provided with an inflatable seal (17).

Abstract: 1329365 Unloading a pallet from a vehicle FRIED KRUPP GmbH 8 Oct 1971 [10 Oct 1970] 47040/71 Heading B8E A load pallet 2 is provided on its underside with a frame 7 by which it is supported on the tilting platform 3 of a truck 1, Fig. 1. To unload the pallet 2 rear jib members, each with a long and a short section 8, 9 are extended from within box girders of the frame 7 and pinned in position by bolts 19, 20, Fig. 11, whereupon the platform 3 may be tilted about its pivot 5 when the pallet 2 will slide down until the jib sections 9 contact the ground 21. Front jib members, each consisting of a short and a long section 10,11 pivoted together at 16 may now be extended and the members 10 secured in position by bolts (not shown). The truck 1 is now driven forward until the front edge of the frame 7 reaches the rear end of the platform 3. The platform 3 may now be tilted further until the angle between the front jib sections 11 and the frame 7 is limited to a defined obtuse angle by stops (13), (17) and (12), (18), Fig. 15 (not shown). The truck 1 is then driven further forward, the pallet 2 sinking to the ground 21 as the front jib sections 11 slide off the platform 3. The truck 1 may then be driven away, the front jib sections 1 dropping to the ground 21. The pallet 2 may be loaded on to the truck 1 by raising the front jib sections 11 by hydraulic jacks 22 attached between the sections 11 and the pallet 2, and reversing the truck 1, with its platform 3 greatly tilted, into contact with the sections 11, Fig. 6. The sections 11 may now be pivoted into line with the frame 7 by the hydraulic jacks 22 and the platform 3 also pivoted into line therewith, Fig. 8 (not shown).  The pallet 2 may now be winched on to the platform 3, the inclination of the latter being gradually increased to maintain full contact. When the position shown in Fig. 11 is reached the power units 21 may be removed and the front jib members 10, 11 retracted. The pallet 2 may now be winched completely on to the platform 3 which is then lowered and the rear jib members 8, 9 retracted. As an alternative to winching the pallet 2 on to the platform 3 the truck 1 may be reversed when the platform 3, front jib sections 11 and the frame 7 are in line and the rear jib sections 9 are secured against slipping on the ground 21. If the platform 3 does not tilt a separate tilting device (23), Fig. 16 (not shown), may be provided for supporting the frame 7.

Abstract: 1,148,926. Oxide-glass resistance film; oxides of Ir and Ru. INTERNATIONAL NICKEL Ltd. 11 Oct., 1967 [24 Oct., 1966], No. 47690/66. Headings C1A and C1M. [Also in Division H1] A composition adapted to be applied to a refractory non-conducting base and fired to form an electrical resistor comprises a mixture of powdered glass with from 2 to 90% by weight of ruthenium or iridium dioxide or both having a crystallite size not exceeding 500. The composition is advantageously a suspension of the mixture of metal oxide and glass in a liquid vehicle. Resistors made from such compositions have temperature coefficient of resistance (TCR) values more negative, and lower current noise values, than those made from metal oxides available commercially which have larger crystallites. To obtain the lowest TCR values the average size of the discrete particles of metal oxide should preferably be between 0À2 and 3 microns. The average size of the non-conducting glass particles is conveniently about 3À5 microns. In an example, the metal oxide particles are mixed with particles of a lead borosilicate glass of the composition 65% PbO, 25% SiO 2 , 10% B 2 O 3  in the proportion 25% dioxide to 75% glass. The mixture was suspended in a liquid medium consisting by weight of 2% ethyl cellulose, 10% dispersing agent, the balance being terpineol to form an ink, which was screen printed on to a base of the refractory material Forsterite (Mg 2 SiO 4 ), dried and then fired at 850 C. to form resistors having an average film thickness of 10 microns. Iridium dioxide of crystallite size less than 500 is prepared by adding sodium bromate to iridium chloride solution, adjusting the pH to 7 with Na 2 CO 3  and boiling. The hydrated iridium dioxide precipitated may be dehydrated by heating in air at 700 C. and ground. Ruthenium dioxide of crystallite size less than 500 is prepared by treating ruthenium chloride solution with NaOH until just alkaline and then acidifying with HCl to a pH 6-7. The suspension of hydrated dioxide may be washed with distilled H 2 O by decantation, then filtered and washed with hot distilled H 2 O. Alternatively, after washing by decantation, the suspension may be dialysed in an ion-selective membrane cell until the aqueous phase shows minimum conductivity. The dioxide may be dehydrated by heating to a temperature less than 500 C. The crystallites have an irregular basically hexagonal shape but often approached a spheroidal form. Reference has been directed by the Comptroller to Specification 1,091,917.
