Title: Production of crystalline dextrose
IPC: C13K1/08
Filed: 1957-08-20
Abstract: The production of crystallized dextrose from starch, e.g maize, sorghum, wheat, rice, potato and tapioca starches, involves pasting the starch with water, thinning the paste with alphaamylase or a strong mineral acid, mixing the thinned paste with dextrose mother liquor, saccharifying the mixture with added amyloglucosidase until the reducing sugars, calculated as dextrose, form at leatt 88% of the solid matter, contacting the liquor with an adsorbent which removes coloured substances and other soluble impurities, contacting the liquor with ion-exchange resins to reduce the ash content of the liquor to not more than 3% of the total solids, concentrating the liquor to 72-80% total solids content, maintaining the syrup so produced under such conditions of seeding, temperature and agitation until at least 50% of the syrup dry substance has been transformed to discrete crystals of dextrose, separating the crystals from mother liquor, the amount of dextrose removed being substantially equivalent to the starch initially used, and returning the dextrose mother liquor for mixing with thinned starch paste.  Saccharifying may be conducted at 50-70 DEG  C. at pH 3-6.  The steps after saccharifying and before seeding may be in any order, e.g. the ion-exchange treatment may precede the decolorizing.  The amyloglucosidases may be from strains of Aspergillus, Clostridium, Mucor or Rhizopus species. Specification 834,334 is referred to.

Title: Improvements in or relating to slicing machines
IPC: B26D7/01
Filed: 1949-10-13
Abstract: 664,744. Slicing-machines. NORRIS, V. R. Oct. 13, 1949 [Oct. 14, 1948], No. 26310/49. Class 28 (ii). A loaf of meat &c. is supported on a stationary plate 24 and driven periodically through a feeding stroke of predetermined length by a feedplate 20 towards a vertically reciprocating knife 19. When slicing is completed the plate 20 is automatically returned for reloading. The plate 20 is secured to endless chains 32, 33 driven from a shaft 44, Fig. 2, the latter receiving its drive from one or the other of oppositely rotated clutches 56, 59. An electric motor 46, Fig 1, drives through gearing a shaft 55 which is connected by a chain and sprocket assembly 57 to the clutch 56. The latter rotates continuously, and when engaged by the shaft 44 drives the plate 20 away from the knife. A cam 63, Fig. 4, on the. shaft 55 actuates a pivoted arm 60 to which is secured a chain 65 passing over a sprocket of the clutch 59 and anchored at its other end through a spring 68 to a fixed collar 69. Reciprocation of the arm 60 rotates the clutch 59 intermittently to drive the plate 20 towards the knife in a series of separate strokes when the shaft 44 and clutch 59 are engaged. Engagement of the clutches with the shaft 44 is controlled by a shaft 70, Fig. 5, threaded to a shifter 73 connected to a block 75. Rotation of the shaft 70 in either direction effects the engagement of pins 85 into clutch 59 or 56 which thereby drives the shaft 44 in one or the other direction. Automatic clutch operating mechanism includes a disc 112 secured to the shaft 70 with an oblique portion 113 against which a spring roller is held. In this position the clutch 59 engages the shaft. A cleat secured to the chain 33 strikes an arm 126 on the disc 112 to rotate it slightly and thereby to disengage the clutch, and a spring 117 rotates shaft 70 still further and causes the engagement of the clutch 56. A cleat on the chain 32 rotates the shaft 70 to disengage both clutches when the loading position is reached. The forward feeding stroke is varied by moving the axially tapered cam 63 along the shaft 55 by a pivoted lever 141 which varies the throw of the lever 60. The lever 141 is controlled from a handwheel 153, Fig. 2, via a threaded shaft (not shown). The knife 19 pivoted on arms 170, Fig. 3, reciprocates diagonally within side members 165, 166 and is driven by a rod 175 connected to a stub shaft 178 driven from a gear 54. An adjustable guide plate, not shown, secured to the knife frame steadies the loaf during slicing.

Title: Improvements in and relating to aerial systems
Inventor: CARY REX HENRY JOHN
IPC: H01Q1/28
Filed: 1947-09-30
Abstract: 649,775. Aerials. MINISTER OF SUPPLY. Sept. 30, 1947, No. 26385. [Class 40 (vii)] The invention relates to unipole aerials for aircraft, a first metallic portion of the aircraft structure being arranged to form the grounded arm of a folded unipole aerial, the fed arm being constituted by a further metallic portion of the structure or a separate conductive element arranged so that its presence causes negligible variation in any of the aircraft's profiles. The most suitable parts of an aircraft structure for such aerials are stated to be the tail-fin or the wing tips and the embodiments described are tail-fin aerials. In a first embodiment the grounded arm comprises the tail-fin itself, the fed arm comprising a wire 11 embedded in insulating material filling a recess 13 in the fin. The wire 11 may be a quarterwavelength long, fed at the lower end, and joined to the skin of the fin at its upper end. An alternative position of the aerial in the fairing at the rear edge of the fin adjacent the rudder 10 is also shown. The supporting structure of the fin may include a vertical box girder with flanges (Figs. 5a and 5b, not shown), the space between the flanges being filled with an insulating material having the fed arm embedded in it. This arm may be in the form of a flat strip. In another embodiment cuts are made in the metallic skin on both sides of the fin as shown at 14, Fig. 3, and a feeder is connected at the point 16. At frequencies at which the fed arm is a quarter-wavelength or less the aerial behaves as a folded unipole, but at substantially higher frequencies it is stated that the aerial becomes a simple unipole formed by the lower half of the fed edge and terminated by the high impedance of a short-circuited stub. Thus the aerial has useful efficiency over two frequency ranges. In a further embodiment (Fig. 6, not shown), the fin surface is divided from the top downwards by an insulating insert and the folded aerial thus formed fed at its top end by a coaxial feeder. In yet another embodiment (Fig. 7, not shown), the rudder itself is used as the fed element of the aerial.

Title: Fluid flow measuring apparatus
IPC: G01P5/07
Filed: 1972-06-06
Abstract: 1439598 Measuring fluid flow-rate electrically D E ABBOTT and C L SMITH 4 June 1973 [6 June 1972] 26395/72 Heading G1N A fluid flowmeter, for use in spirometry, includes a sensor tube 12; a vane 14 mounted within, and rotatable about an axis 16 of, the tube; and an electrically conductive sensing element 18 mounted in the tube and encapsulated or enclosed in a moisture-impervious material, the element being positioned adjacent the periphery of the area swept by the vane on its rotation about its axis, the arrangement being such that movement of the vane relative to the element as a result of passage of fluid through the tube produces a change in the capacitance between the sensing element and the sensor tube. In a preferred embodiment the vane is of a plastics material coated with aluminium and weighs less than one-tenth of a gram. The encapsulating material may be silicon varnish. The element is connected to a transducer unit 30 to amplitude modulate the output of a 2MHz oscillator connected to a demodulator to provide a single pulse output each time the vane passes the element or probe 18. The pulse output from the transducer is fed to a pulse shaper e.g. a Shmitt trigger set to provide a constant amplitude pulse of frequency dependent upon vane rotation speed. This pulse is differentiated and fed to a terminal 40 of a circuit, Fig. 3, for determining the 'tidal volume' or 'vital capacity'. The signal at terminal 40 triggers a monostable mv. 42 so that each of its output pulses enables transistor 44 whereby a reference current from a source +V flows to charge capacitor 52, the monostable pulse width and time constant 50, 52 being chosen so the rise in voltage across the capacitor is linear. The capacitor is maintained at zero voltage by FET 76, until the vane starts to rotate when the pulses from terminal 40 act with transistors 66, 70 to apply a negative voltage to the gate of the FET 76 whereby it goes OFF and capacitor 52 starts to charge to represent the tidal volume being measured. At the end of a breath when vane rotation ceases the FET 76 again short circuits the capacitor. The 'tidal volume' is indicated by meter 58 at the output of amplifier 54 which may also be coupled to a peak sample and hold circuit. If the measurement is taken when the person has inhaled and exhaled fully then the reading on meter 58 or in store (78), Fig. 5 (not shown), is the 'vital capacity'. If a timer is substituted for control circuit 64 a succession of readings can be accumulated for a given time, e.g. one minute, and the total is the 'minute volume'. Fig. 4 (not shown), embodies a circuit including a threshold detector and alarm (92) for patient monitoring. Fig. 5 (not shown) allows the measurement of 'forced expiratory volume', 'maximum forced expiration rate' and 'lung efficiency'.

Abstract: 1278227 Reverberation devices AKG AKUSTISCHE U KINO-GERATE GmbH 19 April 1971 [8 April 1970] 26407/71 Heading H4R An artificial reverberation device includes a glass plate which is mounted to perform bending oscillations. The glass plate, which is 50-80 Á thick and 20 x 30 cm. in area, is supported by thin filaments or tension springs in a frame so that oscillations of over 200 Hz are possible. The plate may be coated so that electrostatic input and output transducers can be used, or if part of the plate is coated to form a mirror, a photo-electric output transducer can be used. As shown, electromagnetic transducers are used for both input and output with diaphragm 9, or the moving coil itself, stuck to plate 1. Echo times may be altered by varying the spacing between sound absorbent plate 11, 12 and plate 1. A buffer plate comprising a rigid perforate plate 13 coated with a thin layer of resilient material limits the vibration and prevents breakage. The device may be enclosed in a sealed casing filled with a gas or gases under pressure.
