Title: Flower pots
IPC: A01G27/04
Filed: 1958-10-30
Abstract: 863,177. Plant pots; watering plants. SZEKELY, G. Oct. 30, 1958 [June 29, 1958], No. 34857/58. Class 6(2). A receptacle for growing plants comprises a flower pot, supplied with moisture via a wick from a water container, the supply being regulated by arranging for the water to be housed in a closed space, and by controlling the air supply to the closed space. As shown in Fig. 1, the receptacle comprises a flower pot 1 having an extended base provided with a screw-threaded flange 2<SP>1</SP> for engagement with a thread round the upper edge of a water container 3 a gasket 4 being interposed between the two. A vent 7, closed by a movable cover 8, is provided in the marginal portion of the base 2, and an aperture is provided in the centre of the base for the passage of the wick 6. In a further modification (Fig. 3), the wall of the flower pot is extended downwards for engagement with the water container, and the air inlet to the container comprises a hollow rib 25 within the pot, closed at one end by a flap 26 or a stopper 27, and in communication at the other end with a hole 28 in the base of the pot. Alternatively, the rib may be omitted and an air inlet formed in the screw threaded flange, so that on unscrewing the pot from the container slightly, air may enter the latter. The device may further be modified by forming the pot and container as an integral structure, providing a controllable air inlet in the wall of the container, or by forming a separate top for the container, in which case the wick passes through a hollow screw screwed through registering apertures in the base of the pot and the top of the container. Mention is also made in the Specification of separating the flower pot and water container, and arranging a wick to pass between the two.

Title: Diatomaceous earth or like filter
IPC: B01D37/02
Filed: 1961-09-28
Abstract: 922,441. Filters. N. F. THOMAS. Sept. 28, 1961 [Oct. 7, 1960; Nov. 17, 1960], No. 34896/61. Class 46. Liquid to be filtered, together with filter aid, is pumped in at 34, Fig. 1, to the interior of a perforate distributer tube 48 and is distributed to form a bed over the interior of a tube of filter cloth 58 enclosed within a wire or plastic perforate screen 56. The screen and tube are clamped at one end to the flange 54 of an end plate 52, the end plate being secured to the spigot part 44 of a coupling 42, the part 44 being in turn connected to the distributer tube 48. The screen and tube are clamped at the other end to the inner end of a barrel 66 secured to an end cover 32. Filtrate is discharged at 28. After filtration the interior of the filter element may be flushed out after opening valve 72 which normally closes the end of barrel 66. Leaves or the like retained within distributer tube 48 may be flushed out after removing a lock pin 84, Fig. 2, from the end of tube 48, and then a pin 74 and a plug 82. The inside of tube 48 may be scraped by a disc on the end of a cleaning-rod (not shown). Pin 74 serves also to locate tube 48 in barrel 66. The assembly comprising the filter element and distributer tube may be removed by loosening end cover 32 from its co-operating casing flange 26, and pulling to disengage the parts 40, 44 of the coupling 42. Instead of valve 72 a radially expandable plug 94, operated by a screw 96, may be used to close the end of barrel 66, Fig. 6, especially when it is wholly within casing 22. Then the end cover 32 may be secured by a transverse bar 90 co-operating with a screw 92 and end stirrups 88 secured to casing 22. Barrel 66 may alternatively be closed by an end cover, bar and stirrups. In Fig. 8 three filter-elements-and-distributer-tube assemblies are arranged in parallel and are fed by a manifold 114. Adjacent each assembly is a dislodging tube 110 having its remote end closed and having perforations facing the filter element. All tubes 110 are fed at 106. Three complete filters may be arranged in parallel, their flushing openings being arranged over a common drainage duct, not all the filters being cleaned at the same time. The filter acid (e.g. diatomaceous earth) may be introduced by an external funnel having a valved outlet pipe pointing downstream in the suction pipe of the pump.

Title: Improvements in or relating to machinery for use in connection with the manufacture of tinplates or sheets and other like plates or sheets
IPC: B21B45/02
Filed: 1932-12-09
Abstract: 410,539. Cleaning metal surfaces. THOMAS, H. S., Melingriffith Works, and DAVIES, W. R., St. Petroc, Park Road, both in Whitchurch, Glamorgan. Dec. 9, 1932, No. 34933. - [Class 99 (ii).] In the manufacture of tin plates or sheets or other like plates or sheets, each bar or billet is carried by a conveying mechanism past means for cooling and scraping the upper surface and is then inverted and carried past means for cooling and scraping the former undersurface. The bars are preferably separated from a pile by a stop member 6, as described in Specification 319,414, [Class 82 (ii)], and each bar is then forwarded by pusher members 5<a> on chain conveyers 5 and the upper surface is cooled by water sprayed from a jet 11 and then scraped by a chisel-edged scraper 8 carried by a pivoted arm 7 acted on by a spring 10. The front edge of the bar then engages within the hook-shaped end 14<a> of a pivoted member 14 which normally hangs substantially vertically between the conveyer chains. As a result of the combined action of the pusher members 5<a> and the member 14, the bar is inverted and is then carried past another cooling jet 13 and scraper 12. A fixed brush 15, Fig. 4, or a rotary brush 17 or both a fixed and a rotary brush as shown may be provided to brush the bar after it has been scraped by the scrapers 8, 12.
Patent GB-973457-A (GB)
Title: Separation process
IPC: B04B1/14
Filed: 1962-09-13
Abstract: <PICT:0973457/C4-C5/1> <PICT:0973457/C4-C5/2> In a process of winterizing a solvent-free glyceride oil, the oil is first chilled to solidify at least a portion of the more-saturated, higher-melting-point glycerides and the mixture of oil and solids is introduced into a zone of centrifugation at the periphery of which the solids accumulate and an outermost portion of the accumulated solids is intermittently discharged from the zone.  The oil-solids mixture is continuously pumped through a feed-pipe 35 into a centrifuge having a motor-driven shaft 32 carrying a rotor 31 which contains a disc pad 38 and is provided with peripheral discharge openings 41a for the separated glyceride solids.  The clarified oil discharges continuously over a ring dam 39.  Each discharge opening 41a has a bushing 41 and is controlled by a reciprocating valve 53 which is normally held on the seat 52 and is operated by a fluid pressure motor 55 to give an intermittent automatic discharge of the solids.  The motor comprises a housing, the base part 57 of which has an annular extension 58.  The valve stem 54 is attached to a hollow piston 61 having a skirt 62 sliding in fluid-tight engagement with a hollow member 79.  Conduits 69, 74 in communication with each other through a channel 72 in the rotor body are connected respectively through bores 76, 77 to the interior of the extension 58 and to a space 78 outside the piston which communicates through a bore 80 with an outlet opening 82 in the rotor wall.  In operation, solids are deposited on to the rotor inner periphery and part of the clarified oil passes through the conduits 69, 74, into the space 78 and under the action of centrifugal force on the oil, the piston and the valve stem, the valve 53 is maintained against its seat.  The solids accumulate in the space 37 where they are compacted under the action of centrifugal force so that occluded oil is freed and travels radially inwards.  The layer of solids builds up radially inwardly in the space 37 until it interferes with the entry of oil through the extension 58 and the bore 76. The leakage of oil from the space 78 via the bore 80 and opening 82 reduces the pressure on the valve 53 which then opens to permit discharge of the solids and closes again as the layer of solids recedes outwards of extension 58 when oil again enters the bore 76 and normal pressures are restored.  In a modification, an opening is provided in the vertical portion of the conduit 69 which is nearest to the bore 76 and oil will flow through that opening to keep the valve closed until the opening is covered by the accumulated solids.  Alternatively, the actuation of the solids discharge valve may be controlled by an adjustable timer or by photo-electric or resistivity measuring means disposed in the clarified oil discharge line. Specification 543,508 and U.S.A. Specification 2,723,799 are referred to.

Title: Improvements in ring spinning machines
IPC: D01H1/20
Filed: 1938-12-01
Abstract: 505,419. Roller-driving gear for ring spinning-machines GESSNER AKT.-GES., E. Dec. 1, 1938, No. 35057. Convention date, Feb. 23. [Class 120 (ii)] In order to maintain the direction of rotation of the rollers in ring spinning machines when the direction of rotation of the spindle-driving shaft is changed, the front roller shaft is operated through ratchet gears 20, 21 connected to pinions 17, 18, which are respectively driven from a shaft 13 by a pinion 14 and pinions 15, 19. The machine is driven by a reversible electromotor which is coupled to the spindle-driving shaft and drives the shaft 13 by a chain and sprocket wheel 10. The arrangement prevents inadvertent loosening of the screw couplings of the rollers which may occur during the usual changing of gears.

Title: Improvements in and relating to current limiting systems
IPC: B66B1/06
Filed: 1953-12-16
Abstract: 745,331. Automatic current control systems. CANADIAN GENERAL ELECTRIC CO., Ltd. Dec. 16, 1953 [Dec. 16, 1952], No. 35066/53. Class 38 (4). [Also in Group XXXVII] The current supplied to the motor of a Ward- Leonard set is limited by energizing two biased, self-saturating magnetic amplifiers in reversed sense in accordance with the current, and connecting their outputs in series opposition to control the excitation of the Ward-Leonard generator. The motor 1 is supplied by the generator 3 which is of reversible polarity, excited from amplidyne exciter 8 controlled by .a main field 9 and the limiter field 10. The current is detected by the voltage drop across an interpole winding 5. This voltage is applied to the control windings 24, 34 of the self-saturating magnetic amplifiers 20, 30 so as to aid and oppose respectively the self-magnetization. Bias windings 27, 32 oppose windings 24, 34. The amplifier loads, 21, 31 are connected in series opposition in series with the field 10 of the exciter. Hence when the motor current is below the level set by the bias windings 27, 32, the small outputs of the amplifiers 20, 30 are equal and opposite, and the field 10 is unexcited. Currents due to any slight unbalance are prevented by the reversely connected pair of contact rectifiers 18. When the motor current exceeds the limiting value the output of amplifier 20 rises rapidly but there is little change in the output of amplifier 30, and the field 10 is excited in a sense to reduce the motor current. When the generator polarity is reversed, amplifier 30 saturates instead of amplifier 20.

Title: A process for the manufacture of ice-cream
IPC: A23L29/256
Filed: 1955-12-13
Abstract: Water-soluble alginic acid amides are incorporated in an ice-cream composition.  At least 40 per cent and preferably 60 to 100 per cent of the total carboxyl groups in the alginic acid amide have been turned to carboamide groups.  The alginic acid amides are produced by the reaction of esters of alginic acid with liquid ammonia or with unsubstituted or substituted amines which contain at least one hydrogen atom on the nitrogen atom as described in Specification 768,309, [Group IV (b)].  The concentration of the amides in the composition is preferably below that which would form a gel at between 0 DEG  and 25 DEG  C. and concentrations of at least 0.1 per cent and preferably 0.2 to 1 per cent by weight are used.  With a concentration of from 1 to 5 per cent a lower degree of amidation is preferable.  The amides may be added to the composition at any time and heating speeds up their solution.  In an example an alginic acid amide was used having approximately 70 per cent of the carboxyl groups converted to carboamide groups, the remainder of the carboxyl groups being present as the ammonium salt.  1.5 parts of this amide are added with 60 parts of sugar to a mixture of 500 parts of full-cream milk, 75 parts of full-cream milk powder and 20 parts of cocoa powder, all parts being by weight.  The resulting mass was heated to about 70 DEG  to 75 DEG  C. and stood at this temperature for from 15 to 20 minutes.  The mixture was then homogenized, cooled to 0 DEG  C., vigorously beaten at between -2 DEG  and 0 DEG  C. when an increase in volume of 50 to 100 per cent took place and then moulded.
