Title: Improvements in devices for spraying freshly printed sheets
IPC: B41F23/08
Filed: 1936-02-04
Abstract: 446,487. Printing-machines. SMYTHHORNE, Ltd., 1, Baldwin's Place, Gray's Inn Road, London.-(Assignees of Rodas Maschinenfabrik R. W. Horne; 37, Leipzigerstrasse, Taucha, near Leipsic, Germany) Feb. 4, 1936, No. 3335. Convention date, Sept. 9, 1935. [Class 100 (ii)] Set - off, preventing.-A spraying device consisting of one or more nozzles 33 is arranged on a printing- machine, over the rear edge of the fly board, for spraying printed sheets with hot wax, or similar substance, adapted to prevent smearing of the sheets, the nozzles 33 being carried by a rocking shaft 11 which causes jets of the spray to be swept across the printed sheet. The container 26 for the wax &c. is carried by an arm 13 attached to the machine frame 1, and the shaft 11 and the control lever 24 for controlling the jets are operated by lever-and-link mechanism from a crank 3 on a one-revolution shaft 2. The crank 3 oscillates by a link 5 a bell - crank lever 6 which reciprocates a rod 9 connected to an arm 10 on the shaft 11. Prior to the oscillation of the nozzles 33 a roller 32 on the rod 9 operates a bell-crank lever 15 which raises a rod 19 connected to the control lever 24, and the lever 24 is held in the open position of the nozzles by means of a spring catch 25. The catch 25 is finally released by a cam 28 on the shaft 11 when the spray is to be cut off, the nozzles then pointing vertically downwards. Motion is transferred from the rod 9 to the lever 15 by means of a roller 32 which acts on a spring-controlled lever 20 abutting against stop 22 on the lever 15. On the downward movement of the rod 9, the roller 32 can snap past the lever 20. The lever 15 is normally pressed by a spring 16 against a stop 12, and the lever 15 is connected to the rod 19 by a pin-and-slot connection.

Title: Device for the evacuation or discharge of silos for beetroots and similar products
IPC: B65G65/28
Filed: 1928-02-02
Abstract: 284,659. F÷lsche, K., and F÷lsche, R., (trading as F÷lsche, R.). Feb. 2, 1927, [Convention date]. Bursting of water-pipes, preventing; pipes, arrangements of.-To prevent freezing in watersupply installations for removing beetroots &c. from storage in silos, underground pipes 12 connected with a main A and pump B and provided with stand-pipe connections 13 for a portable nozzle are laid out so that whichever connection 13 in any pipe 12 is in use the water circulates past every other connection 13 in that branch. The nozzle is connected to any stand-pipe, and a powerful jet of water is directed from it on to the roots so as to drive them into an outlet channel. In Fig. 1, the branches 12 form closed circuits with the main, and when the nozzle is attached to a connection on the branch R', two cocks 11 are opened so as to feed the nozzle from both directions. In a modification (Fig. 2, not shown) the main A forms a loop and the branches 12 are connected across it with a cock near each end of each branch. In Fig. 3, each branch 12 from the main A<0> terminates in a cock 17 which does not completely close, so that water always escapes from any branch 12 in use into an open channel 18. The shut-off valves 14, Fig. 4, on the stand-pipes 13 close tightly only on the lower or pressure side at 19, and water remaining in the nozzle after use flows into the casing 23 and escapes by an opening 25. When the stand-pipe is in use, this opening is closed by a stopper 26 with bayonet-joint. The stopper is carried by a chain on the portable nozzle, so that it must be removed with the nozzle and the stand-pipe above the valve must be drained of standing water. In a modification. Fig. 7, a ball valve 27 moves with the valve-member 14 and closes the drainage aperture 25<1> when the valve 14 is fully opened.

Title: Improvements in or relating to traverse arrangements for cross-winding yarns, threads or the like
IPC: B65H54/50
Filed: 1942-03-16
Abstract: 617,054. Winding bobbins. SOC. RHODIACETA. March 16, 1942, No. 3459. Convention date, March 18, 1941. [Class 120(ii)] A slit or groove-drum traverse mechanism for the formation of regular crosswindings of threads on bobbins or like supports comprises a member located between the drum guide and the receiving support and whereon the thread bears, this member being provided with ends inclined to the longitudinal axis of the drum, so sloped that no sliding of the thread will take place at the ends of the winding. As shown, the said member is constituted by a plate 10 with chamfered ends 12 located between the point 5 at which the thread leaves a slot 3 in the drum 2 and the point 9 at which it contacts the bobbin 6. Ends 12 are so sloped that the resultant thrust P of the thread, which is obliquely inclined at the point of reversal, will not cause the thread to slip on the plate edge as it passes from one side of the slot 3 to the other. A cylindrical roller with conical ends may replace plate 10 and may be used to drive the bobbin 6. The Specification as open to inspection under Sect. 91 comprises also an arrangement for ensuring regularity of the central portion of the winding by providing two guide rods inside the drum, one attached to each end of the drum, located so that the portion of each rod which is visible through the slot is close to one of the reversal points and behind this point relative to the direction of rotation of the drum. This subject-matter does not appear in the Specification as accepted.

Abstract: 457,908. Change - speed gearing; controlling friction clutches. GROTE, E., 5, Carmerstrasse, Charlottenburg, Berlin. Feb. 5, 1936, No. 3497. [Class 80 (ii)] In change-speed gearing, friction clutches 14, 15, 16, 17, Fig. 1, are alternatively engaged by rotary extensible pressure chambers 24, Fig. 3, which are formed by hollow annular bodies of U-shaped cross-section open at their outer edges and there held rigidly. Four of these chambers 24 are shown in Fig. 1 all supported along with the clutch discs in a drum 60 which rotates with a driven shaft 38. The chamber 243 of the clutch 17 is shown with a peripheral duct at 37 leading through an axial duct 36 in the outer wall of the drum 60, and through ducts 36<1>, 44, 45, Fig. 3, to a non-rotary chamber 52 which is supplied with pressure air or liquid through a pipe 48, Fig. 1, fed through a suitable control selector valve (not shown). The thrust of the chamber 24<3> when it expands is taken by a ring plate 29<1> rigidly supported in the drum, and springs 31 are provided for freeing the plates of any clutch when the pressure chamber corresponding is exhausted. There is friction between rotary plates 43, Fig. 3, passing between the distributing chambers 51, 52, &c. which do not rotate. Graphite packing rings 57 are adapted to transmit the thrust of the pressure fluid in spaces 80 to the rotary plates 43. An arrangement is described with reference to Fig. 2a (not shown), having fixed projecting cheeks which ease the pressure with which the rings 57 are thrust against the plates 43.

Title: Improvements in the production of gases rich in hydrocarbons
Inventor: DENT FREDERICK JAMES
IPC: C01B3/38
Filed: 1950-02-10
Abstract: 712,744. Producing gases rich in hydrocarbons. GAS RESEARCH BOARD. Oct. 31, 1952 [Feb. 10, 1950]; No. 3516/50. Class 55 (1) In a process for producing gases rich in hydrocarbons particulate coal or other carbonizable material is hydrogenated in a fluidized state in a current of a hydrogen-containing gas at a temperature of about 800‹ C. or higher and under superatmospheric pressure, and a part of the resulting hydrocarbon-rich gas is catalytically reacted with steam to produce the hydrogencontaining gas for the hydrogenation. The hydrogenation may be conducted in a single fluidized or in two or more fluidized zones as described in Specification 695,192. The heat required for the catalytic conversion of the hydrocarbon-rich gas may be obtained by converting the solid residue from the hydrogenation into producer gas and using the producer gas to heat the vessel containing the catalyst. As shown in the drawing particulate coal is fed into a fluidized hydrogenation zone 2 maintained at a pressure of 25 atmospheres. The resulting gases rich in hydrocarbons pass successively through a cyclone separator 3, a condenser 4, a purifier 5, a heat exchanger 6 to an expansion turbine 7 where the pressure of the gases is reduced to about 10 atmospheres. The gases then are again heated in a heat exchanger 8 and finally expanded to near atmospheric pressure in a second turbine 9 to be withdrawn in part through a line 10 and in part to be used to produce the hydrogen-containing gas required for the hydrogenation in zone 2. This latter portion of the gas is mixed with steam through a line 12 and heated in a heat-exchanger 15 before passing through a series of tubes 14 containing a suitable catalyst, the tubes being arranged in a chamber 13 and heated externally by producer gas obtained by gasifying solid residue withdrawn by line 17 from the hydrogenation zone 2 in a producer 16. The hot combustion products of the producer gas are passed through a waste heat boiler 18 to generate the steam required for the process the steam being expanded in a turbine 20 before it is mixed with the hydrocarbon-containing gas through line 12. The hot hydrogen-containing gas passes through heat exchangers 15, 6 and 8, a condenser 21, a first stage compressor 22, a washer and cooler 24 for removing carbon dioxide and a second compressor 23 where the gas is raised to the pressure at which the zone 2 is operating. The passages through which the hydrogen-containing gas passes in heat exchangers 15, 6 and 8 may contain a catalyst capable of promoting reaction between undecomposed steam and carbon monoxide to increase the hydrogen content of the gas. The compressors 22 and 23 are driven by turbines 9 and 7 respectively. The hydrogenation in the zone 2 is controlled so that the total yield of hydrocarbon-rich gas may amount to 300 therms or more per ton of coal treated.

Abstract: 1530211 Band clamps A & W SCHOBEL OHG 29 Jan 1976 [8 Feb 1.975] 03575/76 Heading E2B  A band clamp comprises a channel-shaped band 10 with a tongue 18 at one end and a head 16 at the other. The head 16 is composed of side walls 30, 32 joined by webs 34, 36 to define a channel 40 into which the tongue 18 is inserted. Teeth 42, 44 are provided on side walls 30, 32 to engage teeth 22 on tongue 18. The head 16 is so constructed that webs 34 lie directly opposite the spaces between webs 36 and vice versa with no overlap (see Fig. 2).  Tongue 18 is provided with a reinforcing strip 20 bearing saw-teeth 24. In order to accommodate this, the webs 36 are bent into a step formation (Fig. 5) so that aperture 40 has a deeper portion 41 of a size corresponding to the reinforced edge and bearing teeth 46 to engage teeth 24. The thickness of the tongue 18 increases from the reinforced to the unreinforced edge and aperture 40 is correspondingly shaped. The tongue 18 is joined to the band 10 by a collar 26 and a reinforcing web 28, diminishing in width towards the centre of the band is provided. Similarly, strengthening heads 48 are provided on the head and web 50 runs from the innermost of these towards the tongue, diminishing likewise in width. Lug 52 with head 54 is formed on this web 50, and teeth 56 are formed on the rib 14 of the channel, directly opposite this lug. The position of this lug 52 is such that it can engage the reinforcing strip 20 of that part of the tongue 18 which has been, in use, passed through the head 18 with teeth 56 engaging teeth 24. To assist in release of the fastened clamp, webs 34 are weakened at 60 so that the tongue may if desired be torn out of the head.

Title: Quantum oscillators
IPC: H03L7/26
Filed: 1963-01-31
Abstract: 1,020,425. Magnitometer; photo-electric measuring. VARIAN ASSOCIATES. Jan. 31, 1963 [Feb. 21, 1962], No. 4103/63. Headings G1A and G1N. [Also in Divisions H3 and H4] In a quantum oscillator with optical pumping of a gas cell 2 located in a uniform magnetic field Ho, the amplified light variations detected by a photo-cell 3 being magnetically coupled back to the cell as shown to produce coherent self oscillations at a magnetic sub-level transition of the gas atoms which also equals their precession frequency in the cell, this frequency (fo) is stabilized by phase i.e. frequency modulating at 11 the feedback at a low frequency to produce a corresponding low frequency output from the photo-cell 3 which, compared with the original modulating low frequency in a phase sensitive detector 14, causes a correcting D.C. output to be applied to a variable shifter 10 in the feedback path to prevent any phase shift and therefore frequency drift of fo. Since fo varies with Ho, its detection at 9 forms a magnetometer. The field Ho may be parallel to the light beam but in that case a further light beam and photo-cell at right angles to the first are required for detecting the light variations. As in Specification 964,027 the light source 1 may be arranged between two similar systems to the above, with the phase modulator output of each magnetically coupled to the other cell to produce the self oscillation fo. Alternatively, in this case, only one phase modulator 11 and phase shifter 10 are used. In a modification of Fig. 3 the output of modulator 11 amplitude modulates, e.g. mechanically chops, the light beam and, to avoid the masking effect of this amplitude modulation at fo of the generated fo, the photo-cell output at frequency 2fo is amplified then frequency divided by two before passing to the phase shifter 10 and modulator 11. Preferably Ho is then at right angles to the light beam. In a modification, as in Specification 974,389, the light beam is intensity modulated at a stable frequency f 1  and the gas cell modulated at the self generated frequency f 2  so that the photo-cell detects the difference frequency (f 1  ~ f 2 ). This is then frequency-converted by f 1  to the frequency f 2  finally passing to the phase shifter 10 and modulator 11. Alternatively the stable frequency f 1  may be applied to the gas cell and the output of modulator 11 to the intensity modulator. In all cases the phase modulator output i.e. generated frequency is stabilized as in Fig. 3. The pumping light beam may irradiate an alkali vapour cell and have the D 2  line suppressed from it by an interference filter, and then is circularly polarised by a polariser. Alternatively a helium lamp may act on helium atoms in the gas cell, the interference filter for the light beam then being omitted.
