Title: Improvements in or relating to methods and apparatus for treating citrus fruit produce
IPC: A23L27/12
Filed: 1961-02-03
Abstract: 972,187. Juice extractors. A. O. T. OSTRUS. Feb. 3, 1961 [Feb. 19, 1960], No. 4189/61. Heading A4C. [Also in Division B1] The fruit and hulls of citrus fruit produce such as oranges, lemons and limes, are rapidly shredded by a cutting action finely to subdivide the produce to separate and to release therefrom shredded portions and the flavour and other fluids contained there in the form of a flowable mass, the shredded portions and the flavour and other fluids are sprayed at the place of subdivision with an aqueous fluid, the resultant flowable mass is subjected to a centrifuging and filtering step to effect separation and removal of non-filterable portions of the flowable mass from the situs of the filtering step, and the resultant aqueous filtrate containing the flavour and other fluids is recovered. Citrus fruits fed through an inlet 40 are carried over a shredding disc 42 rotating at 1,750 r.p.m. and furnished with radially aligned and angularly spaced teeth 56 which extend upwarly from the disc 42 a distance of 20/1000 of an inch. The fruit produce, now shredded to less than 40/1000 inch thickness, passes through holes in the disc 42 into a vertically adjustable pipe 16 wherein a "rounded" spray of water is directed from four angularly-spaced nozzles 38, such that the spray actually comes into contact with the cutter disc 42. The shredded mass is separated into juice and pulp in a basket 18 reinforced by axially and radially aligned ribs 68 welded to horizontally extending ribs 7, and suitably rotating at between 350 and 470 r.p.m. The juice passes through the screen 20 of the basket into a casing 24, from which it is removed through an outlet conduct 26, whereas the pulp progresses upwardly along the peripheral surfaces of the screen and is driven into the casing 108-116-118. A relatively flat fan-shaped aqueous spray is directed towards the screen 20 from nozzles 78 in adjustable spray pipes 36. The spray liquid may be either water or recirculated juice. Additional ingredients may be introduced through the pipes 36 so that, as the pipes are adjusted, citric acid solution is introduced at the lower portion of the basket, sugar at an intermediate portion and wash water or stabilizing solution at the top. Additional ingredients may also be added to the juice after its passage to the outlet 26. The aqueous spray liquid is metered through solenoid-operated valves in direct proportion to the electronicallydetermined quantity of fruit produce being subdivided, so that the aqueous filtrate (juice) contains at least 1.0% by volume of the recoverable volatile oils of the fruit. According to one example, lemons were fed into the cutter at the rate of 38 pounds per minute and sufficient additional processing solution was added through the nozzles 38 to capture the flavour, at a rate of 0.03 U.S. gallons per minute, to yield a product having 1 ml. of volatile oil in 100 mls, of total base.

Title: Current pulsing arrangements
IPC: H02M1/06
Filed: 1972-01-28
Abstract: 1383535 Control of D.C. motors SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALTHOM) 28 Jan 1972 [29 Jan 1971] 4220/72 Heading H2J [Also in Division H3] The D.C. pulsing circuit more particularly for providing pulses of a duty cycle extending to less than 5%, comprises a switching device such as thyristor 2 connected in series with a capacitor 5 which is in parallel with an inductor 6 and a bidirectional switch 3, 4. If capacitor 5 is assumed to be charged in series aiding relation to the supply voltage E, firing thyristor 2 will cause a short pulse to flow in a load such as motor 8 while the capacitor discharges and then reversely charges to the supply voltage. Firing thyristor 3 will now resonantly reverse the voltage across the capacitor to its original value and firing thyristor 2 will produce a further load pulse. If however, prior to firing thyristor 2, a thyristor 4 is fired, of resonant reversal the voltage across capacitor 5 commences. Thus, when thyristor 2 is fired the pulse applied to the load is reduced, the energy supplied by the pulse being dependent upon the delay between the firing of thyristors 4 and 2. To apply pulses of larger duty cycle to the load a thyristor 1 is fired and subsequently commutated by firing thyristor 2 to apply the reverse voltage across a capacitor 5 to thyristor 1. The commutating capacitor 5 is charged during the conduction of thyristor 2 and its voltage is subsequently reversed ready to effect the next commutation by firing thyristor 3. Thyristor 4 is not used for the larger duty cycle pulses. The back-to-back thyristors 3, 4 may be replaced by a triac.

Title: Products having a pile-like surface of rubber elements and apparatus for manufacturing such products
Filed: 1951-03-01
Abstract: <PICT:0710182/III/1> <PICT:0710182/III/2> <PICT:0710182/III/3> A pile-like rubber surface or a pile-like surfaced rubber sheet, is produced by depositing commingled coagulated and uncoagulated particles of rubber from an aqueous dispersion of natural or synthetic rubber on a fabric or piece 57 of rubber, fabric, cardboard, or fibrous composition, which may be precoated with rubber cement 58, or on a temporary surface from which the resultant sheet can be stripped, to form discrete or connected protuberances 53.  A pair of compressed air spray guns 15, 16. Figs. 1, 2 as described in Specification 601,395 depend from transverse track 22 on which they are moved back and forth across conveyer belt 10, or fabric 47 supported on conveyer belt 10.  The spray guns 15, 16 are angularly adjusted with respect to each other and the fabric 47 or belt 10, so that the sprays of rubber dispersion from gun 15 and coagulant, e.g. aqueous formic or acetic acid, from gun 16 impinge a short distance from the guns and form a flat fan-shaped combined spray 35 extending lengthwise of the fabric 47 or belt 10.  When the rubber dispersion is sprayed direct on to the belt 10, this is lubricated with soap solution to assist in stripping the resultant rubber sheet from the belt.  A third spray gun 37 depending from track 39, on which it may be moved back and forth, directs a fan-shaped spray 40, extending lengthwise of the fabric 47 or belt 10. of rubber dispersion only at the fabric or belt.  The volume ratio of coagulant to total rubber dispersion may be between 1 : 1 and 1 : 25.  The spraying zone is bounded by electrodes 42 connected to the negative pole of D/C generator 45, which confines the spray between the electrodes to avoid wastage, and induces a negative charge on the particles, which are consequently attracted to the surface due to the positive charge induced thereon by earthed plate 13.  The belt or fabric may have an embossed or engraved surface, may be passed through the coating zone twice, and may have the coating applied to selected areas.  In an alternative arrangement, Fig. 4 (not shown), three superposed spray guns are provided, the upper and lower of which supply rubber dispersion, and the middle gun supplying coagulant, the resulting streams meeting to form one fan-shaped stream.

In a fuel injection pump 1, delivery is ended by a shuttle valve 7 controlling a spill conduit 6, 6a, the shuttle valve being operated by liquid delivered by an auxiliary pump 9, which also pumps liquid into a chamber 20. The pump 9 and chamber 20 are supplied with fuel from a pump 28. At slow speeds the volume of the chamber 20 varies with the piston stroke of the pump 9 and only amounts of fuel insufficient to open the spill passage 6, 6a act on the shuttle 7. As the speed increases the volume change of the chamber 20 decreases owing to the restriction 21 and increasing amounts of fuel act on the shuttle, which, owing to a restriction 16, is progressively raised, thereby increasing the amount of fuel spilled. In alternative embodiments the restriction 21 is dispensed with or a speed governor acts on the piston 22 so as to reduce the volume of the chamber 21 progressively.

Abstract: 677,764. Teaching and training aviators. BUTLER, J. E. March 1, 1951 [March 6, 1950], No. 4994/.51. Class 4. [Also in Group XV] Apparatus for simulating the operation of aircraft may be in model form or of such a size that the operator may be located in the apparatus. In the embodiment illustrated in Figs. 1, 3, 4, a piano 10 is supported by means of a boom 12 on an electrically propelled, remotely controlled wheeled member 11. A control box 13 has a switch 15 controlling a battery driven motor 25, and a control stick 1 enables member 11 to be steered and the plane to be raised or lowered and to perform banking movements. A running wheel 23 is mounted for steering and is pivoted by control stick 16 acting on a steering pin 73 and steering rod 71 contained in a control casing 69. The movement of the boom 12 in a vertical plane is effected by a cable 43 which also passes through the casing 69. The plane is banked by the movement of a cross member 74 mounted on a steering yoke 72, cables 51, 52 from member 74 passing over a pulley 50 affixed to boom rod 36 which is thus axially rotated. A parallelogram rod 37 keeps the plane in a constant longitudinal attitude when the plane is level. When the plane is banking, however, the rod 37 becomes effectively shorter due to yoke 53, to which the rod 37 is pivoted, not turning laterally when the rod 36 is rotated, and the nose of the plane is elevated to produce the simulation of a climbing turn. In a modification, Figs. 9-14 (not shown), cables from the steering cross member pass along the boom and are connected to the wings of the plane which is mounted on a longitudinal pivot. Reversible gearing and clutches controllable from the stick 16 may co-ordinate the raising and lowering of the plane with the motion of the wheeled member 11 and a flywheel may be provided to enable an acceleration and glide effect to be simulated. The batteries 28 may alternatively be in the control box or power may be supplied from an external source through a flexible line preferably leading to the control box. The operator may be in the wheeled member or in the plane.
