Title: Improvements in or relating to rollers having exchangeable facings, more particularly for the treatment of textile goods, stockings and the like
IPC: D06C15/08
Filed: 1936-02-05
Abstract: 468,400. Rollers. SCHUSTER, F. Feb. 5, 1936, No. 3462. Convention date, Dec. 10, 1935. [Class 42 (ii)] [Also in Group XIII] A hollow metal roller 7 with an exchangeable rubber facing 8 for treating textile goods particularly stockings is characterized by perforations 16, Fig. 3, in the cylinder which allow moisture to pass into the interior. The layer of rubber forms with the hollow cylinder, which may be of thin sheet steel or iron, a unit which can be readily transported and is not affected by heat during vulcanization. The mounted portion 1, 9, 10, Fig. 1, of the roller may remain in the machines so that readjustment of bearings 2, 3 after exchange is unnecessary. The cylinder 7 is tensioned between the discs 9, 10 which are adjusted by a nut 6. Annular recesses 13 in the discs accommodate the cylinder 7. In a modification, the edges of the recesses 13 are substantially inclined to facilitate introduction of the cylinder 7. In another modification, the discs 9, 10 may be provided with openings to allow free discharge of liquid. The cylinder 7 may be open at both ends, but a hollow cylinder open at one end only may be used, the other end being wholly or partially closed. In another modification, a facing cylinder similarly covered and perforated may be slipped over a supporting cylinder.

Title: Improvements in and relating to photographic cameras
IPC: G03B7/00
Filed: 1958-02-03
Abstract: 880,781. Photographic cameras. VOIGTLANDER A.G. Feb. 3, 1958 [Feb. 2, 1957], No. 3525/58. Addition to 852,732. Class 98(1). In a photographic camera of the kind described in the parent Specification, locking means is provided between the diaphragm adjusting member and the shutter speed adjusting member, to prevent the movement of the shutter speed adjusting member to a setting for which no corresponding stop value is available in accordance with the light value required for the exposure. As shown, the diaphragm blades, exemplified at 1, are pivoted at 2 to a shutter speed setting member 3 and have pin-and-slot connections with a diaphragm adjusting member 6. Member 6 carries the diaphragm aperture scale 7, and a light value scale 8 which co-operates with a fixed index 9. The shutter speed setting member 3 carries an index 11 cooperating with both the diaphragm aperture scale 7 and a fixed shutter speed scale 10. As described in the parent Specification, when the diaphragm adjusting member 6 is set to a selected light value on scale 8, the shutter speed setting member can be adjusted to a desired shutter speed and the diaphragm will automatically be set to a value appropriate to the light value, provided that index 11 is not moved beyond the end of the diaphragm aperture scale 7; in which case the diaphragm aperture adjusting member 6 is moved so that the light value setting is altered. To prevent this, spring-loaded levers 12, 13 are pivoted at 14, 15 on the shutter speed setting member 3. Normally their end lugs 16 bear on the edge of the diaphragm adjusting member 6; but when the index 11 reaches either end of scale 7, the lug of the corresponding lever enters a recess 21 or 22, and the other end of the lever engages one of two fixed sets of teeth 19, 20 to prevent further rotation of the shutter speed setting member. The levers may carry lugs such as 23, extending out of the shutter casing, whereby the levers may be disengaged from the teeth at will to allow overtravel when desired.
Patent GB-689280-A (GB)
Title: Catalytic cracking heat exchange process
IPC: C10G11/18
Filed: 1951-02-14
Abstract: <PICT:0689280/III/1> In a process for the cracking of a petroleum oil fraction such as gas oil using fluidized catalyst, followed by fractionation of the cracked products, the oil feed supplied to the reactor and the catalyst-in-heavy-oil slurry withdrawn from the base of the fractionating column are passed in heat-exchange relationship; and the gummy material deposited in the heat-exchanger by the oil feed is removed by periodically interchanging the flow-paths of the two streams within the heat-exchanger so that the slurry flows through (and cleans) the path formerly traversed by the oil feed, and vice versa.  The apparatus shown in the Figure represents a fluidized, dense-bed catalytic cracking unit comprising a reactor 1, catalyst-regenerator 2, and a column 10 in which the products (which contain a small amount of entrained catalyst) withdrawn from reactor 1 through line 5, are fractionated.  The upper part of column 10 contains plates 11, and the lower part contains disc and donut packing 12.  An over-head fraction is withdrawn from column 10, and side streams are withdrawn through lines 14 and 15. A slurry containing about 0.4 lbs. of catalyst per gallon of heavy oil, at a temperature of about 650 DEG F, is withdrawn from the base of column 10 through line 16, and is subdivided into two streams.  One stream of the hot slurry is passed through heat-exchanger 17, wherein it is cooled by water (which is vaporized to steam); the cooled slurry is then re-introduced into column 10 through line 19.  The other stream of hot slurry is passed through the coils 20 of heat-exchanger 18, while the oil feed at about 250 DEG F is pumped via line 21 around the outside of coils 20 on its way to reactor 1.  By this means the slurry is cooled to about 450 DEG F, and the oil is heated to about 400 DEG F.  The cooled slurry withdrawn from heat-exchanger 18 is in part discarded from the system and in part recycled to fractionator 10 through line 19.  After about 15 days of operation, the outsides of coils 20 become fouled, and the flows of slurry and oil are interchanged (see dashed lines on Figure) so that the slurry passes around the coils while the oil passes through them. The slurry takes about 48 hours to clean the outsides of the coils, after which the original flow-paths are operated again.

Title: Improvements in or relating to apparatus for controlling the supply of limited quantities of electric energy
IPC: G01R11/56
Filed: 1919-02-14
Abstract: 142,214. Anninger, M. Feb. 14, 1919. Electricity, supplying by meter.-An energy meter is adapted to open a switch when a predetermined amount has been delivered. A spindle 1 has keyed to it a dial 5 and a disk 6 having a projection 12 at one part of its circumference, and is driven counter-clockwise from the meter through a clutch 3, 4 and a loose wheel 2. The spindle 1, and with it the dial 5 and disk 6, is set to the predetermined amount by turning with a key or spanner in a clockwise direction. A watch spring 1<a> is thereby wound up and serves to keep the teeth of the clutch members 3, 4 in engagement. When the amount has been delivered, the projection on the disk 6 lifts one arm 10 of a bellcrank lever, thereby allowing a switch arm 8 to be opened by a spring 17. A key-operated bolt 14 normally closes the setting-aperture 19. When retracted to expose this aperture, the bolt 14 recloses the switch 8 through a crank 16 and lever 18. When the dial has been set, the bolt 14 is returned to its normal position, thereby removing the lever 18 from the switch arm 8 and leaving this supported by the short arm 11 of the bellcrank lever.

Filed: 1922-02-08
Abstract: 197,388. Bowden Wire, Ltd., and Nisbet, A. H. Feb. 8, 1922. Controlling-apparatus, arrangements of hand, foot, and transmission gear in conjunction with; flexible transmitters. - Relates to means for coupling a movable or controlled member to two or more Bowden wire or like transmission members so as to permit of independent actuation, as for example in hand and foot control of the throttle valve of a carburettor on a motor vehicle, the arrangement being such that the movable member may be actuated through either transmission member w i t h o u t affecting the setting of the other. According to the invention two or more separate Bowden or like wires g leading from independent controlling members are connected to spring retracted tubular members f, f<1>, slidably mounted in grooves or channels c, c<2> in a two part casing a.. Lugs h, h<1> on the lower ends of the members f, f<1> engage a block d slidably mounted in a central groove or channel c<1> in the casing and connected, preferably through a Bowden wire e, to the throttle or other part to be controlled. When the block d has been moved a short distance by actuation of one of the transmission members g it is still free to be actuated further by the other transmission member g and such actuation does not interfere with the setting of the first transmission member. The device may be modified to actuate two or more movable or controlled elements. The casing a may be fixed, as by screws through lugs b or it may be loosely hung in position.

Filed: 1939-02-06
Abstract: 526,741. Actuating controllers with auxilary switches; handles. HEATON, F. Feb. 6, 1939. No. 3805. [Class 38(iii)] A controller comprises contacts 27 moved stepby-step by reciprocation of a handle 10 towards and away from the front face of a panel behind which the switch gear is mounted. The handle is first moved against spring bias from its horizontal to a vertical position, to free a member 36 and. then pulled, the energizing circuit for a main contactor being thereby energized and placed under control of an inclining switch 38. By movement of the handle beyond its vertical position the inclining switch is opened and it may be reclosed at will to give inclining control. Further reciprocation of the handle operates through a pawl 20 to move the contact 27 whereby the motor is accelerated, the energizing circuit for the main contactor then being completed through an auxiliary switch on the main contactor so that the inching control is then not available. A stop switch 44 is operated by a knob 11 and in addition to the opening of the main contactor the pawl 21 is operated by a member 31 to release the contacts 27 which return to their initial position, a retaining pawl 29 being simultaneously released. An isolating switch 53, 54 is operated by rotation of a handle 12 which also operates a switch 63 in the control circuit. The handles 12, 10, and the knob 11 are arranged in a horizontal line on the front of the control panel.

Title: Method of manufacturing fibre products
IPC: D04H1/56
Filed: 1966-01-28
Abstract: Fibrous products,-e.g. filters or thermal insulating fabrics-are produced by forming a web from fibres spun from a linear polymer-e.g. a polypropylene, a polyamide, or a polyester-drafting the web, condensing the web and heat setting the web in the condensed state. A pre-heated air stream directs the fibres from the spinning nozzles onto a cylinder or belt, to which suction is applied, to form the web.  The web is drafted by roller pairs, with, in one embodiment the drafting being controlled by rubber ribbed rollers.  The web is compressed by being stuffed between two metal conveyor belts heated by superheated steam, with the compressed web being cooled on a further conveyor by sucking air through it.  Alternatively, the web is sandwiched between an oiled silk fabric and a lining fabric and pressed by a profiled cylinder heated to a temperature of 160 DEG . A filter is formed by putting the condensed web in a sieve mould placed in a chamber heated to 150 DEG C.

Title: Improvements in couplings for protected or armoured electric cables for use under water and elsewhere
IPC: H02G15/10
Filed: 1919-02-18
Abstract: 143,308. Gibson, V. C. H. Feb. 18, 1919. Cable and wire terminals; plug coupling and connectors; sleevc connectors; sleeve couplings.-A coupling for armoured cables for use under water or elsewhere has. gripping and holding devices for the strands of wire armour, through which the wires pass in an undulating fashion, and means for coupling the ends of the conductor or conductors. As shown in Fig. 1, a perforated cap n and a thick lead, rubber, or other compressible washer s are threaded on to the ends of cable to be jointed, and the hempen or other textile fabric is removed as far as the lead washer. The wire strands are then passed through one or more holes or grooves in a metal collar q, and a metal core u is passed over the insulation and within the armour wires, so that these lie between the inner openings of the collar q and a ring 3 formed on the metal core u. Rings 5, 4, 6 and a gland 7 are then slipped alternately over and under the wires and successively driven home by a hollow drift. The ends of the wires are trimmed off, and a coiled spring 10 and second gland 11 may be added to maintain the gripping pressure when strain is put upon the cable. A sleeve 9 is screwed to the collar q, and a hollow plug 2 screwed into its inner end to secure the whole. To make the joint water-tight, washers v, y and a screwed collar z may be employed to compress a rubber washer w around the insulation.- Fig. 5 shows a modified grip for the armour, in which a collar 17 similar to the collar q is used and the wires are taken from this collar through a sleeve 13, which may be divided longitudinally, threaded in and out through holes 14 therein, and bent over its inner end, where a screwed cap 15 clamps them. The armour coupling, in both forms, is completed by a sleeve b, which may have a union joint h and is screwed at each end to take the caps n. It has enlarged bores at each end provided with keyways to take the collars q or 17 without permitting them to turn. The conductor or conductors may be coupled by plug-and-socket couplings separated by a perforated diaphragm f. The conductor coupling may be enclosed in a sleeve 21 and made water-tight by caps 19 screwed thereon and adapted to compress rubber washers surrounding the insulation of the conductors and disposed within the sleeve 21.
