Abstract: 415,125. Feeding sheets. WAITE & SAVILLE, Ltd., Falcon Works, and WHYTE, F., The Evergreens, both in Otley, Yorkshire. Feb. 20, 1933, No. 5124. [Class 100 (i).] Apparatus for feeding sheets from a pile to printing and like machines is adapted to feed sheets of paper or cardboard of different thicknesses and comprises suction nozzles b moved vertically to pick up the sheet and horizontally to carry the sheet under a guide d towards the machine, and a screw adjustment 7 for controlling the downward limit of the vertical movement of the nozzles. The guide d is formed with slots through which the nozzles descend to engage the topmost sheet of the pile a and slide horizontally to forward the sheet ; on the return horizontal movement the nozzles are raised within or above the slots to clear the pile. The horizontal movement of the nozzles is effected by means of a carrier bar reciprocated on guides y by a link connection with an oscillating lever w, and the vertical movement is effected by means of slotted brackets m<1> which guide the nozzles horizontally and are actuated from an oscillating shaft q through an upper pair of levers p<1>, which in conjunction with a lower pair of levers p maintain the brackets in a vertical path. The extent of movement of the shaft q is controlled according to the thickness of sheet by means of a stop arm 5 on the shaft co-operating with the adjustment screw 7 and a fixed stop 6. For thin papers an air blast is used to assist separation and raise the topmost sheet against the guide d; for thick cardboard or like sheets the air blast is dispensed with and the nozzles descend farther into contact with the top sheet on the pile.

Title: Improvements in or relating to the manufacture of cellulose acetate
IPC: C08B3/06
Filed: 1931-02-19
Abstract: Cellulosic material, after being subjected to pretreatment with acetic acid vapours, is acetylated by using baths of two types, the bath of the first type comprising acetic acid in excess, acetic anhydride, and a catalyst, and the bath of the second type comprising acetic anhydride in excess, acetic acid, and a reduced quantity of catalyst, the process being characterized by the application of the bath of the second type in at least two additions, each addition being of identical composition and added only after the reaction due to the previous addition has subsided. In an example, cotton fibres are dried down to 2 or 3 per cent moisture content and treated in known manner with approximately their own weight of acetic acid vapour, a part, at least, of which is condensed on to the material. The primary esterification is carried out using a bath comprising 85 per cent acetic acid, 15 per cent acetic anhydride, and 0,3 per cent sulphuric acid, which may be applied in two or more stages.  The acetylation proper is carried out using two or more additions of a bath comprising 15 per cent acetic acid, 85 per cent acetic anhydride, and 0,1 per cent sulphuric acid, the reaction being allowed to subside between each addition.  The resultant cellulose acetate is then partially hydrolyzed and the sulphuric acid residues removed by the process of Specification 282,789, [Class 2 (ii), Cellulose &c.].  The product contains approximately 55 per cent acetyl groups measured as acetic acid.  Specifications 282,788, 303,135, and 305,096, [all in Class 2 (ii), Cellulose &c.], also are referred to.

Abstract: 159,214. Bulle, M. P. Favre-. Feb. 19, 1920, [Convention date]. Indicating rest or motion.-Apparatus for indicating unauthorized use of a vehicle comprises an oscillatory mass adapted under the influence of vibrations due to movement of the vehicle to impart irregular movement to the spindle of a pointer, the positions of which before and after the period of control indicate the extent of use of the vehicle during the period. In one construction, a mass 2 carried by a member 3 pivoted at 4 and supported by a spring 5 is formed with a nose 6 adapted to engage the side faces or the ridge of a similarly shaped end 14 of the arm of a pendulum 13, thereby oscillating the pendulum or depressing the rod 9 by which the pendulum is carried. When the nose 6 engages the ridge of the end 14 and depresses the rod 9 against the resistance of a spring 12, a pawl 8 carried by the rod 9 rotates a ratchet pinion 7 on the pointer spindle. Thus the pointer is advanced around the dial irregularly. The oscillations of the pendulum 13 alone are insufficient to depress the rod 9. In another arrangement, a single mass 13<1>, Fig. 1<a>, pivoted to a hinged arm 3<1>, is fitted with a nose to engage a similar projection on the arm 9' carrying the pawl. The pointer spindle may drive a second pointer through reducing gear, the two pointers having the appearance of clock hands, as shown in Fig. 2. One of the attachment screws 16 of the instrument may be sealed. The masses may be carried on the ends of blade springs, instead of being pivotally mounted. Rigid or resilient stops for the oscillatory members may be provided.
