A continuous web of envelopes 1, formed from a single web of paper folded on to itself about a longitudinal edge 2 to form flaps 3, is separated by transverse lines of perforations 9, and has a longitudinal band of self-adhesive material 6 extending preferably along the uppermost surface of flaps 3 with the band of self-adhesive covered with a continuous protective strip 7, which is wider than the band of self-adhesive and the strip is provided with holes 10, where it crosses the lines of perforations so that the envelopes may be easily separated and the web of envelopes folded without buckling of the strip. The holes 10 are not as wide as the protective strip 7 so that the strip is continuous and not likely to catch in a machine and may be pulled away in a continuous strip. To seal the envelope the flap 3 is folded along an edge 4 of the upper surface and pressed down after the protective strip has been peeled off. Holes 8 are provided on each side of the web along the longitudinal edges 2 to facilitate passage of the envelopes through e.g. a tabulating machine. Specification 536,628 is referred to.
Patent GB-259213-A (GB)
IPC: F04B9/10
Abstract: 259,213. Sch÷neberger, F. Sept. 29, 1925, [Convention date]. Liquid-pressure engines. -In a gear operated by water, air, or steam, the auxiliary piston C is oscillated by a pin S connected to a shaft C<1> receiving motion from the engine. The pin divides the interior space into chambers k, k<1> which are connected by radial boxes to peripheral slots d, e, d<1>, e<1> having closed ends. The chambers k. k<1> communicate through ports p, p<1> respectively with the ends of the piston C which are recessed to facilitate the distribution of fluid. Assuming the piston S at the top of the chest, fluid passes through passages e<2>, b, d, o, chamber k, and port p to the top of the chest and forces the piston down. Fluid beneath the piston exhausts through port p<1>, chamber k<1>, and passages o<1>, e<1>, b<1>. Fluid pressure passes by slot E to the passage a connected to the right of the main horizontal cylinder to move the main piston to the left. The left-hand end of the main cylinder exhausts through passages a', f', g. As the main piston moves to the left the piston C is oscillated, the other slots d, e are brought opposite the passages b, b<1> whereupon the piston C is raised and the main distribution is reversed.

Title: Forage harvesters
IPC: F16D23/12
Filed: 1974-06-12
Abstract: 1507830 Forage harvester "CLAYSON" NV 11 June 1975 [12 June 1974] 25999/74 Heading A1F [Also in Division F2] A forage harvester comprises a blower 11 and a cutter head 10, driven independently by belt drive transmissions 35, 34, and a double-acting clutch comprising two belt tensioner clutch members in the form of tension pulleys 45, 40 mounted on pivotable supports 46, 41, and a single control lever 50 is operable initially to cause the tension pulley 45 to engage the belt 35 which initiates driving of the blower and subsequently to cause the pulley 40 to engage the belt 34 so that the cutter head is also driven. Thus the blowing operation commences before and finishes after the chopping operation to ensure that forage material does not cause blockages. Belts 35, 34 extend between respective pulleys 33, 32 and pulleys 31, 30 on output shafts 22, 21 of a gearbox 91 connected to an engine 5. The pivotable supports 46, 41 of the pulleys 45, 40 are pivotable around the respective output shafts 22, 21 of the gearbox 19 and are connected by a rod 80 in co-operating sleeves 77, 78 and a lever 69 respectively to respective rock arms 68, 67 of a rock member 63. The rock member, with a central rock shaft 64, can be pivotally moved by linkages connecting it to the handle 50. In a first extreme position of control handle 50, neither pulley 45 or 40 contacts its respective belt. but, on movement of handle 50 to an intermediate position, the rock member pivots and the rod 80 and sleeves 77, 78 are arranged to give an angular movement to the support 46 to move pulley 45 into contact with belt 35 to drive the blower means. The lever 69 is so positioned that its pivotal movement does not cause movement of support 41, since, although rock arm 67 pivots from right to left as viewed in Fig. 2 thus moving the left-hand end of lever 69, the right-hand end of lever 69 remains in the same position. If the handle is moved to a second extreme position, lever 69 now causes angular movement of support 41 to move pulley 40 into contact with belt 34 as shown in Fig. 2 to drive the cutter head, but the movement of rod 80 and sleeves 77, 78 does not cause further angular movement of support 46, so driving of the blower means continues. Compression springs 79, 75 are provided on the rod 80 and lever 69 respectively and ensure that the tension in belts 35, 34 is maintained at the appropriate value.

Title: Improvements in the manufacture of yarns, fabrics, films and the like of organic esters of cellulose
IPC: D01F2/28
Filed: 1935-09-23
Abstract: Filaments, yarns, foils, films, and similar formed materials having a basis of an organic ester of cellulose are esterified with liquid media comprising anhydrides of lower fatty acids dissolved in diluents with the aid of perchloric acid as catalyst. Preferably, the materials have a basis of cellulose acetate and are esterified with acetic anhydride.  The proportion of perchloric acid used is of the order of 0,1 to 0,2 per cent of the weight of the yarn.  Diluents specified are benzene, xylene, tetra-and deca-hydronaphthalenes, kerosene, normal and iso butyl and amyl ethers, and carbon tetrachloride.  Small proportions of swelling agents for the cellulose ester may be present, e.g. acetone, methylene ethylene ether, methylene dichloride, and acetic acid.  The amount of acetic anhydride used for esterification is usually about 1 to 1\ba1/2\be times the weight of the material.  The yarns used may be produced by the ordinary spinning process, or it may be a yarn which has been stretched, shrunk, dyed, or the like.  Stretched yarns require a higher proportion of catalyst than normal yarns, e.g. from 0,5 to 1 per cent of the weight of the yarns.  The cellulose ester yarns which have been further esterified show an increased resistance to heat, a reduced moisture regain, a greater resistance to water and to delustring by hot water or steam, a reduced affinity for dispersed insoluble dyestuffs, and modified solubility characteristics. Specifications 389,823, 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, 443,707, 443,773, and 448,817 are referred to.

A voltage control system for a D.C. excited inductor alternator has an amplifier feeding a control field, the amplifier power supply being derived by tapping the alternator output winding. An alternator IA has a main field winding MF supplemented by a control field winding CF. The output winding OW supplies terminals T1, T2 via a capacitor C which balances the winding inductance. The output voltage is reduced by transformer TR and compared in circuit CC with a reference voltage from source CV. The difference or error voltage is applied to the control winding of magnetic amplifier MA, the power supply for which is obtained by tapping across a portion TP of the alternator winding OW and as this supply varies with the error signal a greater output is produced than would be obtained by the use of a constant voltage supply. The error signal is inverted in MA to vary the excitation in winding CF in a corrective sense. The excitation may be supplied by the controlled winding only, the winding MF being omitted.

Title: Improvements in automatic weight totalisers as applied to flexible conveyors
IPC: G01G11/02
Filed: 1931-09-23
Abstract: 380,603. Weighing-apparatus fitted to conveyers. BROWN, S. C., 40, Gloucester Road, North Harrow, Middlesex. Sept. 23, 1931, No. 26550. [Class 143.] An automatic weigher and weight totalizer fitted to an inclined endless conveyer is provided with auxiliary mechanism to compensate automatically for the fluctuating error which would otherwise be present in the weight records due to the variations in friction at the weighing idlers under fluctuating loads. As shown in Fig. 1, the weigh table 2a, supporting a portion of the conveyer A by means of idlers 2, is carried as usual by links B2, B3, levers B, B1, and an automatic weighing resistant D. The disturbance due to fluctuating friction at the idlers 2 is compensated for by connecting the weigh table by a link E3 to a pendulous resistant E<1> fulcrumed on a stationary pivot E2 and connected at the upper end to a link F6. An horizontal movement is thus given to the link F6 by the vertical movements of the weigh table, and the link F6 rocks a weighted lever F1, Fig. 3, about a knife-edged pivot F2 so as to move the weighted lever to one side or the other of the fulcrum B4 of the lever B1 thus compensating for the frictional disturbance at the idlers 2 caused by the pull of the inclined conveyer. In a modification, Fig. 2, where the weigh table is in three sections G, 2a, H, as described in Specification 365,768, the section H is provided with a bell-crank arm H1 terminating in a knife-edge H2 bearing upon a stationary bearing H3. The tendency of the table to move laterally under the pull of the inclined conveyer is resisted by the bell-crank arm H1 which tends to rock the section H about the fulcrum 4, and thus influences the weighing system so as to compensate for the error caused by the friction at the idlers.
