Title: Granulated sodium metasilicate
Inventor: MOCKRIN ISADORE
IPC: C01B33/32
Filed: 1956-05-22
Abstract: A granular sodium silicate which can be blended with other materials, e.g. for detergent compositions and consisting of an intimate bonded mixture of anhydrous and a hydrated sodium metasilicate may be prepared by adding 0.2-0.4 parts by weight of water to 1 part by weight of anhydrous sodium metasilicate, said mixture containing not more than 3% of sodium hydroxide, and blending.  It is preferred to add the water rapidly whilst blending the anhydrous silicate until a translucent appearance is obtained and then continuing the blending for at least 1/4 hour until the mixture is uniform.  If the anhydrous silicate has been crystallized from an alkaline solution, it is necessary to wash the material first, preferably with aqueous sodium metasilicate.  The resulting granules have a melting point of 63-70 DEG  C. and contain sodium metasilicate hexahydrate and possibly pentahydrate.  By heating at as low as 150 DEG  C., preferably under vacuum, a substantially anhydrous granular material can be obtained.

Title: A solution and method for cross-linking cellulose, and the products obtained
Filed: 1962-04-26
Abstract: Cellulose in the form of textile fibres and fabrics, particularly regenerated cellulose, is treated with formaldehyde in the presence of zinc fluoborate.  The cellulose may be impregnated with an aqueous solution of formaldehyde and zinc fluoborate and cured, e.g. by heating at 100 to 180 DEG C.  The solution may contain 0.5 to 6% of formaldehyde and 0.3 to 3.5% of zinc fluoborate and may have a pH of 1 to 5, preferably 2 to 5. The quantity of zinc fluorborate applied to the cellulose may be at least 0.2 gram, and preferably 0.35 to 4.5 grams, per 100 grams of dry cellulose.  The process improves the resistance of the cellulose to swelling by water and permits of the mercerisation of regenerated cellulose fabrics and improves their dry crease recovery.  The cellulose may be in the form of never-dried viscose rayon fibre (see Division B5).  The process is said to crosslink the cellulose.  Specification 930,132 is referred to.

Filed: 1969-03-27
Abstract: 1,249,739. Discharging articles from shoots. USM. CORP. 27 March, 1969 [28 March, 1968], No. 15989/69. Heading B8S. [Also in Division B3] A machine for mounting components C on workpieces B includes automatic feed means 8. The components C are supplied from a'dispensable magazine 230, which contains several vertical stacks of components and is provided with lugs, which slide within a notch 234. The magazine is moved stepwise by gears (180), (182), (200), (202), Fig. 5 (not shown), and operation of a switch LS10 indicates to the feed mechanism that a stack is empty, thereby withdrawing a plunger (222) and allowing rotation of the gears so that a new stack of components is aligned with a shoot 20, whereupon the plunger is returned. The bottom component C of the stack is held by a spring-loaded rod 28 towards the top of the shoot 20. An air motor 32 is actuated to withdraw a rod 30, which abuts the other end of the spring 36, loading the rod 28, and a spring 26 pivots a member 24 so that a lower limb thereof enters the shoot. As the rod 30 withdraws, the spring pressure is reduced and the component stack moves down on to the lower limb of the member 24. The rod 30 is then advanced, thereby loading the rod 28 to hold the stack and pivot the member 24, whereupon the bottom component falls on to a gate 40. A cylinder 42 moves the component laterally so that a lead straightening operation may be performed. Should no component be present, the switch LS10 is closed, thereby resetting the apparatus for a new cycle. An air motor 70 opens the gate 40 when a component is present and it moves down the portion 21 of the shoot, coming to rest on a bar 84.

Title: Sheet registering mechanism
IPC: B41F21/10
Filed: 1950-06-30
Abstract: 710,175. Feeding sheets. HOE & CRABTREE, Ltd., R. June 30, 1950 [July 1, 1949], No. 16455/50. Class 100 (1) Sheet-registering devices. - Mechanism for registering a sheet on a rotatable registering cylinder comprises means for advancing the sheet over the surface of the cylinder, a preliminary register means for stopping the advance of the sheet, final register means for forcing the leading edge of the sheet into a predetermined registered position with reference to the cylinder, and means operating to hold the sheet rearwardly of its leading edge while that edge is forced back and the leading portion of the sheet is caused to buckle. After stopping the movement of the sheet, and prior to front registration, the sheet is side registered by suction or other means. The invention is described as applied to known sheet-feeding apparatus wherein sheets s are fed to a rotating registering cylinder 1, Figs. 1 and 6, by means such as belts 2, where they are registered and then conveyed to a printing or other cylinder by grippers 6, 7 on bars 5. The bars 5 are carried by endless conveyer chains, and each bar is adapted to enter the gap in the registering cylinder 1. Each sheet engages front stops comprising a number of spring fingers 15 secured to a rock shaft 16 operated from a cam 23 which rocks a shaft 20 connected to the shaft 16 by a bell-crank 19 and links 17a, 17. Then a suction bar 3 operates to register the sheet laterally, suction is applied through holes 31 in the cylinder surface to grip the sheet, rearward of its leading edge, to the cylinder, and the shaft 16 then rocked to force the spring stops 15 against a register bar 30 so that the sheet is buckled as shown in Fig. 6. The suction valve box 33, Fig. 1, is controlled by levers operated from the shaft 20. The register bar 30 is clamped in position by bolts and eccentric studs, whereby it can be distorted, if necessary, to a curved or other form to compensate for irregularities in the sheets. In a modification, instead of suction means a camcontrolled roller may clamp the sheet to the cylinder. In the form shown in Fig. 9, a rockable shaft similar to the shaft 16 described above, carries two sets of front stop spring fingers 50, 51, the fingers 50 engaging the sheet first for preliminary registration and co-operating with a register bar 52, and the fingers 51 co-operating with projections 53 of a register bar 54 for final registration of the sheet. The bar 52 is recessed, as shown, to accommodate the projections 53 and the grippers. The shaft is rocked in two stages, the leading edge of the sheet being buckled in the second stage, as described above. Both register bars are capable of distortion to compensate for irregularities in the sheets. Sheet-detector means of known form comprise fingers 8, Fig. 6, deflected by the sheet to allow a bar 10 secured to a shaft 9 to swing clockwise when the shaft is rocked. If any finger has not been deflected, the shaft 9 cannot rock, the sheet is rejected, and the printing mechanism tripped.
