Title: Improvements in or relating to envelope-making mechanism
IPC: B31B50/56
Filed: 1931-04-24
Abstract: 370,674. Making envelopes. MOND, A. L., 19, Southampton Buildings, London. -(Smithe Machine Co., Inc., F. L. ; 633, West 44th Street, New York, U.S.A.) April 24, 1931, No. 12238. [Class 94 (ii).] Envelopes 36 having their side flaps gummed and folded and their closing flaps creased but unfolded are fed from a table 37 by feed rolls 21, 22 against stops 10 on a table 4, the stops being so positioned that the closing flap just clears the nip of the rollers which thereby align the envelope against the stops. The stops 10 are adjustably mounted in slides 9 adapted to be reciprocated in guides 12 which are adjustable laterally of the machine along a cross-bar 3 secured to stanchions 2 on the main frame. The slides 9 are linked to arms 7 secured on a rock shaft 5 journalled in the stanchions 2 which also support a second rock shaft 6 carrying spaced fingers 35b projecting towards the roll 21, 22. As soon as the envelope is adjusted against the stops 10, the fingers 35b move downwards to wipe the closure flap against the roll 22 and fold it about its crease. The fingers then hold the envelope on the table 4 and prevent it buckling while the stops 10 move forward to thrust the fold of the closure flap between the roll 22 and an idler roll 25. The idler roll 25 is carried by curved arms 24 pivoted on a shaft 20 and rocked by a cam 30 engaging a cam roller 28 on an arm 27, to press the envelope during the passage of the closure flap only. Further folding pressure is applied by a resilient roll 23 comprising bristles, or having a cover of sponge or pneumatic rubber. As the envelope passes beneath the fingers 35b, it depresses a curved portion 40 of an arm 39 normally projecting through an aperture in the central finger 35b, and the arm 39 which forms part of an arm 38 secured to a shaft 37, rocks the shaft to actuate a counting mechanism.

Title: Preparation of aminohaloboranes
IPC: C07F5/02
Filed: 1961-04-05
Abstract: The invention comprises aminohaloboranes of the general formula RB(X)NR12, wherein X is a halogen atom and R and R1 are the same or different and are alkyl groups of 1-6 carbons atoms or aryl groups, provided that where R is alkyl one or both of the R1 radicals are aryl groups.  Examples of such novel compounds are chloro(dimethylamino)phenylborane, bromo(di-p-ethylphenylamino)methylborane, chloro(diethylamino)p-anisyl borane, chloro(diphenylamino)phenylborane.  Aminohaloboranes of the formula RB(X)NR12 as defined above but without the proviso, are made by effecting reaction between a secondary amine of general formula R12NH and a dihaloorganoborane of general formula RBX2, and treating the product with pyridine or a tertiary alkyl amine having primary or secondary alkyl groups of 1 to 4 carbon atoms.  The reaction between the secondary amine and dihaloorganoborane is preferably effected at a temperature between -80 DEG  and 0 DEG C. and the resulting mass is brought to about room temperature and is then agitated with a tertiary amine until the aminohaloborane has been formed.  Where R and R1 or both are aryl, the preferred radicals are phenyl, phenyl-substituted phenyl, naphthyl, or alkyl or alkoxyl-substituted phenyl in which the alkyl or alkoxyl groups contain 1 to 5 carbon atoms.  The preferred starting materials are the chlorine and bromine compounds, but fluorine and iodine compounds can also be used. The products are valuable chemical intermediates and herbicides.

Title: Process and apparatus for the exchange of heat between gaseous, vapour like or liquid bodies
IPC: F28D11/04
Filed: 1926-05-18
Abstract: 252,373. Maschinenfabrik Ing. H. Simmon. May 19, 1925, [Convention date]. Fluid-friction apparatus; cooling and heating parts. - A hollow drum - shaped ribbed body traversed by one medium is rotated in a ventilator casing through which the other medium is moved by the. friction between the medium and the ribs which extend in the direction of the rotary movement. As shown in Figs. 1 and 2, for the exchange of heat between gases, the rotatable body comprises sheet - metal rings 1 spaced apart by distance rings 2 and secured to a disc 4 by bolts 3. The disc 4 is fixed to a shaft 9 driven by a pulley 8 and the body is enclosed in a casing 10 with inlet and outlet openings 11, 12 for hot gases, which are entrained and moved through the casing by the rotating body. A pipe 13 having radial blades 14 projects from the side of the casing 10 into the rotary body, cold air being admitted around this pipe and the heated air drawn off through it. Centrifugal action forces the cold air into the spaces between the ribs 1, displacing air already heated, and also forces soot, ashes, &c. in the hot gases through a slot to a chamber 15, from which they can be removed by a worm 16. Fig. 3 shows a modification in which the ribs are formed by a helically wound metal strip 17, between the convolutions of which is arranged a helically wound bar 18 mounted by spiders 19 on a shaft 20 driven by a pulley 21. The casing 22 has an inlet 23 and outlet 24 for hot gases arranged so that the gases are impelled through the casing by the helical rib 17, the air being forced through the rotating body by a fan 25 and discharged at 26. Spiral ribs running in opposite directions may be cast inside and outside the rotating cylinder so that the ribs impel both the hot gases and the air in opposite directions. In further modifications intended for heating liquids the rotatable body comprises two hoods 28, Fig. 5, connected to discs 30 fixed to a spindle 29, the hoods being mounted on hollow journals 27 for the supply and discharge of the liquid. Ribbed pipes 31 are mounted between the discs 30 and the body is enclosed in a casing 33 with inlet and outlet openings for the hot gases, arranged so that the body moves the hot gases through the casing by fluid friction. Centrifugal action causes the cold liquid in the inlet hood 28 to displace the heated liquid in the pipes 31, rendering a pump unnecessary. Adjustable deflecting plates for the hot gases may be fitted in the casing. The Specification as open to inspection under Sect. 91 (3) (a) comprises also statements that the ribs may be omitted or replaced by pins. This subject-matter does not appear in the Specification as accepted.

Abstract: 706,429. Treating clay in pug-mills. ENGLISH CLAYS LOVERING POCHIN & CO., Ltd.. and CLARK, N. O. May 29,-1952 [June 4, 1951], No. 13204/51. Class 86. In a process for treating .material such as precipitated chalks, clays and the like, such material being of particle size in the region of ten microns and below (equivalent Stoke's diameter), a filter-cake of the material having its moisture content reduced by at least 4 per cent. compared with the moisture content of a filter-cake pressed at 100 p.s.i. is passed through a pug-mill, so constructed that energy of more than 8 horse power hours can be absorbed per ton of output. In the treatment of clay, the clay has its moisture content reduced to between 27 per cent. and 22 per cent. before feeding to the pug-mill. The desired moisture content may be obtained in a drier or by the addition of dry clay to the wet clay, the quantity of added dry clay being controlled as a function of the power required to operate the pug-mill. The pug-mill is provided with a heavier augur than usual and the gap between the augur and the casing is relatively wide. As described the pug-mill has an outlet formed by plates 2 and 11 each having a plurality of matching outlet holes 4 and 13 respectively, the plate 11 being angularly displaceable so as to vary the effective size of the outlet orifices. The arrangement may be such that approximately 30 horse-power hours is absorbed per ton of output.

Abstract: 132,058. Western Electric Co., (Western Electric Co.). Sept. 14, 1918. Wireless signalling.-In a wireless transmitting system, the circuit of the high-frequency oscillation .generator includes the plates and filaments of one or more pairs of thermionic valves, and the grid-filament circuits of these valves are also supplied with high frequency oscillations from the same generator, these oscillations being modified in amplitude or in phase by a microphone or other signalling instrument. As shown in Fig. 1, the circuit of the high-frequency source 1 includes a coil 2 coupled to the aerial and a pair of thermionic valves 31, 32 connected oppositely to the leads 21, 22, thus forming a path for each half of the current wave. In shunt across the source 1 are placed an inductance 12 and resistance 13, and an intermediate tuned circuit including a microphone 15 is coupled thereto by the variable loose coupling 12, 14 and by making an adjustable portion of the resistance 13 common to the two circuits. A coil 16 in the intermediate circuit is coupled to two coils 19, 20, which are placed respectively in the grid-filament circuits of the two valves 31, 32, and supply modulated oscillations 180 degrees out of phase to the two grids. By adjusting the contact 18 and the variable coupling 12, 14 the potential variations on the grids may be brought into phase with the current across the plates and filaments. The grids are maintained at a normal negative potential by the batteries 41, 42. In a modification, the shunt circuit. 12. 13 is replaced by a circuit coupled inductively to the coil 2 in the main circuit. In a further modification, shown in Fig. 3, the pair of valves 31. 32 are placed in parallel with the coil 2 across the leads 21, 22 from the high-frequency source 1. The microphone 15 may be replaced by an instrument, for example, a condenser transmitter for varying the inductance or capacity in the intermediate circuit, thus throwing this circuit out of tune and changing the phase relation between the potential variations on the grids and the plates.
