Title: Improved apparatus for screening material, in particular an improved pea viner
IPC: A01F12/00
Filed: 1963-02-20
Abstract: 961,272. Screening apparatus. FMC CORPORATION. Feb. 20, 1963, No. 6808/63. Heading B2H. A screening apparatus for screening pea or bean crops comprises a rotary screen drum 40 mounted as by rollers 43 in a frame 10 and a screen beater 120 arranged to periodically beat the screen 60 by reciprocating driving means 100. Vines bearing the crop are fed into the end of the drum where beaters 55 break open the hulls to release the crop. The hull particles and crop are discharged on to a conveyer 62 through the screen 60 and the vines are carried away on another conveyer; the screen 60 is flexibly-made of nylon string material and the beater 120 serves to flex the screen to dislodge any particles. A separating- conveyer 70 directs the crops to a conveyer 80. The screen beater 120, which has resilient fingers 122, is spring-loaded so as to pivot about its pin 104 on to the screen. The fingers are lifted intermittently by a pin 146 reciprocated by the driving means 100, the pin engaging a latch 148 on an arm 102 which is secured to and rotates with the beater. When the latch 148 has been retracted to the position shown in Fig. 3 it is released so that the beater will spring back on to the screen. The pin 146 is attached to a slotted link 130 driven by a crank 130 from the drum-driving mechanism and guided over a pin 142 which is itself vertically-slidable within a slotted bracket 156 mounted on the frame 10.

Abstract: 1,041,002. Reservoir pens; ink receptacles. H. A. A. EXNER. Feb. 15, 1965 [Feb. 19, 1964], No. 6871/64. Addition to 986,822. Heading B6P. Reservoir pens.-In a retractable stylographic fountain-pen having separate ink openings 33, Fig. 1 (not shown), and a capillary material within the reservoir, as described in parent Specification 986,822, the counterweight 10 for the ink needle 24 is provided with a flexible shock-absorbing element 14 which engages with a connecting bar 15 when the reservoir and writing element are in the retracted position. In so doing, the tapered front portion of the ink needle co-operates with the rear of the nib section to seal-off the writing tube and prevent leakage of ink when the pen is not in use. The reservoir of the pen may be filled by first removing the reservoir and writing element from the pen, applying an aspirator, Fig. 4 (not shown), to the respiratory opening 29 in the side of the reservoir, and withdrawing air from the reservoir whilst the nib section is immersed in ink. The aspirator may be the cap of an ink receptacle. Ink receptacles.-An ink receptacle 32, Fig. 5, is provided with a pump mechanism to force ink into the reservoir of the pen. Entry of the nib section into the receptacle may open a valve member, Fig. 7 (not shown), screwed into the conical seat 31 of the receptacle. Fig. 6 (not shown) illustrates a flexible reservoir which is compressed to force ink into the reservoir. The flexible reservoir may also be supplied with a valve which is opened by inserting the nib of the writing element.

Title: Improvements in or relating to elastic yarns
IPC: D02G3/32
Filed: 1932-03-09
Abstract: 380,368. Elastic yarns. ADAMSON, P., Milton Gardens, Rye, New York, U.S.A. March 9, 1932, No. 7057. Convention date, June 11, 1931. [Class 120 (iii).] An elastic yarn comprises a rubber core held under tension by a covering of fibrous material so that the yarn has a predetermined limit of stretch, the diameter of the yarn being less than À025 of an inch. The core may be made from any high grade vulcanized rubber composition, but a core made from 60 per cent rubber latex capable of low temperature vulcanization is preferable. The core may be made by streaming an aqueous dispersion of rubber into a coagulating bath. The fibrous covering is applied whilst the core is uniformly stretched, and may be of cotton, linen, flax, silk, rayon, wool or the like, and may be braided or, preferably, of right and left-hand closely wound helical windings of like or different materials. The yarn can be used in high speed fine gauge knitting-machines, the stretching capacity of the yarn being limited to 100 per cent for such use. The yarn may be used on sewing-machines and may be woven or knitted into bandages, garters, hose, bathing suits and other articles of wearing apparel. Specifications 214,615, [Class 70, Indiarubber &c.], and 370,761 are referred to.

Title: Apparatus for dispensing liquefied gases
IPC: F17C5/02
Filed: 1958-03-07
Abstract: 860,663. Storing and dispensing liquefied gases. UNION CARBIDE CORPORATION. March 7, 1958 [March 11, 1957], No. 7349/58. Classes 8(2) and 102(2). Transfer of liquefied gas, e.g. oxygen from a portable insulated container 10, Fig. 1. to a consumer's tank 16 which initially is at a pressure higher than that within the storage container 10 is effected by first equalizing the pressure in containers 10, 16, e.g. by connecting a transfer line 22 to a filling line 21 and allowing a pressure build-up through a check valve 40 in a line 39 leading to the gas space of container 10 sufficient to lift a bellows 46 and hence a valve 41 from its seat at the discharge end of a vaporizing coil 43 embedded in the insulation 15 and drawing from the base of the container ; the vaporized gas traversing the valve 41 being fed to the gas space of the container and serving to discharge liquid therefrom up syphon tube 38 through couplings 22a, 23 and line 21 to the container 16. On completion of the transfer, the coupling 23 is detached and that end of line 22 is coupled to a filling line 19 to effect opening of a normally closed valve 49 and equalization of pressure on oppposite sides of the bellows which is then collapsed by spring 41b and closes the valve 41 which in turn prevents circulation of vapour and possible rise in pressure within the container 10. The filling line 21 of the container 16 extends to the base thereof but has axially spaced slots 48 giving access to the gas space. A gas service line 60 is connected by a heating coil 64 embedded in the insulation 15 to a T- piece 90 which may be supplied either with gas through a line 74 when the pressure in the gas space is sufficient to lift a bellows 86 to open a valve 84 or with liquid forced up a syphon tube 66 and which is vaporized in the coil 64. A portion of this liquid is vaporized in a pressurebuilding coil 96. In a modification the underside of the valve-actuating bellows 46c, Fig. 2 instead of being open to the gas space of the container 10 is connected bv a line 46 to a lateral bore 46e of the coupling socket 25a. The valve 41 is thus opened immediately and the pressure in the gas space of container 10 is raised to the necessary level to effect discharge by vaporization of liquid in the coil 43.

Title: Motion transmitting control assembly and a modulator valve including such a control assembly
IPC: G05G7/02
Filed: 1976-02-25
Abstract: 1498562 Bowden mechanisms; linkwork; change-speed control TELEXFLEX Inc 25 Feb 1976 [10 March 1975] 07439/76 Headings F2D and F2K A modulator valve (not shown) of an automatic vehicle automatic transmission (not shown) is connected to a throttle linkage (not shown) via a flexible remote control cable 40, 50 of a control assembly 10, the cable 40, 50 including a lost-motion, i.e. spring connection 58 whereby the cable core 50 may be pre-loaded via a removable C-section spacer sleeve 78 so that when the assembly 10 is connected between the automatic transmision and throttle linkage, a plunger 26 of the control assembly 10 is arranged to engage with and apply a predetermined load to the modulation valve for correct calibration thereof after which the spacer sleeve 78 is removed and no further calibration of the modulator valve is required. As shown, the cable core 50 is connected via the spring 58 to one arm 36 of a bell crank lever 28 pivoted at 30 in a housing 12, the other arm 38 of the bell crank directly engaging one end of the plunger 2,6 the other end of which engages the modulation valve. The spacer sleeve 78 is initially fitted between the flexible cable outer casing 40, 46 and a sleeve 54 fast on the core 50 to tension the core 50 and thus pre-load the spring 58, the bell crank 28 being retained against a stop 76 in the housing 12. The control assembly 10 is then fitted to the automatic transmission via a telescopic sleeve assembly 80, 82 and positioned such that the plunger 26 is engaged with the modulator valve to the extent that a force of, e.g. 15 lbs., is applied to the plunger 26 by the modulation valve to move the bell crank arm 36 away from the stop 76 and the telescopic sleeve assembly 80, 82 then tightened by a connection 24. Thereafter the free end 56 of the core 50 is attached to the throttle linkage and the spacer sleeve 78 removed whereby the modulation valve control assembly is automatically correctly calibrated.

Title: Improvements in or relating to machines for packing cigarettes and like articles
IPC: B65B19/10
Filed: 1930-03-07
Abstract: 350,015. Packeting cigarettes. HOR. GAN, G. D. and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. March 7, 1930, No. 7484. [Class 94 (i).] In machines for packeting cigarettes, and in which a hopper outlet is provided with vanes 2, Figs. 3 and 4, arranged to form vertical channels from which a conveyer removes the cigarettes in batches, the lower extremities 4 of the vanes are formed independently of the upper portions 2 and are mounted in a transversely movable frame. At the beginning of the feeding operation, the lower portions are in alignment with the upper portions, and the cigarettes fall to the table 3. The frame is then moved so that the lower portions 4 of the vanes are intermediate of the upper portions, as shown in Fig. 4. In this position, the upper edges of the portions 4 support the cigarettes between the portions 2, and a pusher 11 removes those between the portions 4. The frame then moves back to the original position and the cigarettes above, having been supported horizontally, fall parallel with the machine bed. In a modification, Fig. 7, the lower parts of the vanes are formed in two independent series 13, 14, and are arranged to move so that the cigarettes fall from above only half the total descent at a time. The vanes are spaced sufficiently widely apart to allow ample room for the movements of the cigarettes, which are brought into compact formation for packeting by feeding the batch through converging guides 16, auxiliary pusher pieces 18, which may be as described in Specification 349,424, going out of action when the width of the batch has decreased sufficiently to allow it to be wholly engaged by the pushers 11. This is effected by mounting the pushers 18 on auxiliary conveyers 19 so that they pivot about a pin 22 and fall beneath the table 3 when the heel 25 passes the end of a guide 24. When the cigarettes are to be packeted in twenties, one row of six is associated with two of seven. The outer vane 15, Fig. 7, of the lower series may be formed with a stop so that the lowermost row contains only six cigarettes, a filler 17a being introduced between the guides 16. If the row of six is to be in the middle, the extra cigarette from the middle row is caused to travel downwards during the compression by a guide 17, Figs. 3 and 5. When the row of six is to be at the top, the two left-hand cigarettes, Fig. 5, are simply allowed to drop to the level of the table 3.

Title: Butyl rubber catalyst system
IPC: C08F210/12
Filed: 1965-02-22
Abstract: A major amount of a C4 to C7 isoolefine is copolymerized with a minor amount of a C4 to C14 di- or multiolefine using a catalyst system comprising an anhydrous hydrogen halide and a dialkyl aluminium monohalide AlR2X, where R is a branched or straight chain C1 to C12 alkyl and X is fluorine, chlorine or bromine, at a temperature between 0 and - 100 DEG  C., the mole ratio of anhydrous hydrogen halide to dialkyl aluminium monohalide being no greater than 0.05:1. The preferred polymer is obtained by reacting 95 to 99.5% by weight of isobutene with 0.5 to 5% by weight of isoprene. Cyclodiolefinic compounds such as cyclopentadiene, methylcyclopentadiene and compounds such as b -pinene or divinylbenzene may be incorporated with the isoolefine either in addition to or in place of the diolefine.  The polymerization may be carried out in bulk or in solution.  In the examples isoprene is copolymerized with isobutene and methylcyclopentadiene is copolymerized with isobutene.
Patent GB-398510-A (GB)
Title: The manufacture of products containing nitrogen
IPC: C07C209/08
Filed: 1932-03-14
Abstract: Those bases obtained according to the process described in the parent Specification which still contain halogen are subjected to a heat treatment as such or with the addition of a copper catalyst or an acid-binding agent and/or a suitable diluent at a temperature ranging from about 200-300 DEG  C. at ordinary or elevated pressure.  The resulting bases have a lower halogen content and are more strongly unsaturated in character; they are of primary, secondary, and tertiary type, and in some cases contain admixed small quantities of quaternary ammonium compounds; they are, either as bases or in the form of their organic or inorganic acid salts, auxiliary agents for the textile industry, in particular the aqueous solutions of the salts possess wetting, dispersing, and softening properties and improve the fastness of substantive dyeings to boiling water and acid.  They may be sulphonated according to the process of Specification 383,736 or by condensation with sodium chlorethanolsulphonate to give other useful products in the textile industry.  Instead of the bases themselves their neutral or basic salts may be used as starting materials; in all cases at the end of the reaction the pyro-bases are in the form of their soluble hydrohalides and may be precipitated out by adding alkali.  In examples, (1) the product obtained by heating a tetrachlorinated hard paraffin with alcoholic ammonia at 100-200 DEG  C. in a closed vessel is further heated at 200-215 DEG  C. for a few hours; on adding alkali a pyro-base almost free from chlorine is obtained; the base may also be heated in presence of dimethylaniline to give a similar pyro-base; (2) the base obtained by heating a dichlorinated hard paraffin with alcoholic ammonia at 160-170 DEG  C. is further heated in monochlorbenzene at 250-255 DEG  C. for 4-5 hours; (3) the base obtained by heating a hexachlorinated hard paraffin with alcoholic ammonia at 140-150 DEG  C. for some hours is further heated with addition of copper powder at 210-220 DEG  C. for 2-3 hours; (4) the base obtained by heating a trichlorinated hard paraffin with ammonia solution at 100-200 DEG  C. is further heated in the form of its hydrochloride with sodium carbonate at 210-220 DEG  C. for 4-5 hours; the sodium carbonate may be replaced by dimethylaniline or pyridine to give a pyrobase having a smaller chlorine content.
