Title: Improvements in or relating to animal foods
Inventor: SAUNDERS JAMES
IPC: A23K1/00
Filed: 1965-06-22
Abstract: 1,076,676. Animal foods. CEREBOS FOODS Ltd. June 9, 1966 [June 22, 1965], No. 26391/65. Headings A2B and A2Q. A process for making animal food comprises heating a food mix comprising cereal and water to gelatinise the starch and extruding during and/or after heating (e.g. by friction, hot air or steam) to form shaped food masses (e.g. cubes or pellets) which are bonded by gelatinised starch and which have a density of at least 1.1 g/cc. The shaped masses are dried e.g. by hot air. The food mix may comprise wheat, wheat flour, maize, barley, oats, soya beans, soya bean meal, white fish meal, meat meal, bone meal, herring meal and offals. The shaped masses may be mixed with meat pieces and gravy, filled into cans and steamed in vacuo and heated at 260F. As shown, the heated food mix supplied by hopper 8, is forced through the openings in rotary die 10 by rollers 6 and cut into pellets or cubes by knife 7, the pellets faling on to rotary sifting plate 12 and deflected therefrom by plate 11 through an opening in wrapper plate 1. The position of the rollers is adjustable.

Title: Improvements in or relating to charge forming devices for internal combustion engines
IPC: F02M21/00
Filed: 1928-09-22
Abstract: 297,459. Delco-Remy Corporation, (Assignees of Aseltine, F. E., and Teeter, W. H.). Sept. 22, 1927, [Convention date]. Dashpots. - In a carburetting apparatus provided with a spring-loaded suction-actuated main air inlet valve 33, the movements of the valve are retarded by a dashpot, to provide for enriching the mixture on acceleration, and to prevent fluttering of the valve when the throttle is suddenly opened. The dashpot comprises a cylinder 170, Figs. 9 and 10, adjustable in a sleeve 184 in the float chamber, holes 185, 186, being provided in the sleeve and in the cylinder below the fuel level. Within the cylinder is a piston 171, Fig. 14, sliding on a piston rod 172 secured to the lower end of the air valve spindle 150. The piston rod has a flange 174 against a rim 175 on which the piston is normally pressed by a spring 176 bearing against an adjustable nut 177. The piston and flange have holes 178 - - 180, a check valve 181 for the latter being provided. A by-pass 187, Fig. 10, has its upper end normally covered by the piston. When the throttle is opened at low or intermediate speeds, suction is transmitted to the valve 33, and it descends but not with sufficient force to compress the spring 176; the movement at first is therefore slow. As the by-pass 187 is uncovered however, the fluid resistance is reduced and the valve opens more rapidly. The greater the throttle opening at the time of acceleration, the less will be the retarding action. Under certain conditions, e.g. coasting, when there is a very sudden increase in depression on reaching a level or an incline, it is not desirable to retard the opening movement. In such a case, the vacuum is great enough to compress the spring 176 so that the flange 174 is separated from the piston permitting escape of fuel through holes 178. To provide an additional retardation, the dashpot 'cylinder may be raised as the throttle is opened by a bifurcated arm 192, Figs. 9 and 10, which is actuated from the shaft of the throttle valve.

Title: Improvements in or relating to battery-charging circuits
Inventor: ADAMS FRANCIS JOHN
IPC: H02J7/00
Filed: 1960-07-29
Abstract: 974,492. Charging and discharging batteries. PYRENE CO. Ltd. July 31, 1961 [July 29, 1960], No. 26492/60. Heading H2H. A thermistor 4 is connected in parallel with a resistance 5 of lower ohmic value which carries the trickle-charge current of a battery 1, the arrangement being such that when the voltage of the battery 1 falls below a predetermined value the voltage across thermistor 4 increases causing it to pass a higher current which then progressively increases with the thermistor temperature, the maximum charging current being determined by a resistance 6. In a modification, Fig. 2 (not shown), the thermistor is used to control a transistor which is connected in parallel with the trickle-charge resistance and carries the increased charging current consequent upon a fall in the battery voltage, this current being limited by resistors in series with the transistor. The transistor may be replaced by a silicon-controlled rectifier and the thermistor by a Zener diode. The Provisional Specification states that further transistors may be connected in parallel with th e first transistor and arranged to conduct when this transistor passes current.

Title: Improvements in radio ranging systems
IPC: G01S13/34
Filed: 1945-10-12
Abstract: 621,848. Radiolocation. PARTINGTON, G. E. Oct. 12, 1945, No. 26762. Drawings to Specification. [Class 40 (vii)] [Also in Group XL (b)] In a frequency-modulated radar system, wherein the reflected energy received by a directional aerial rotating in azimuth is mixed with transmitted energy to give a beatfrequency signal indicative of the ranges of reflecting objects, the beat-frequency signal is applied to a plurality of frequency-selective circuits with each of which there is associated an indicator, the indications provided by the indicators being arranged in a straight line in order of range values and rotated in synchronism with the aerial rotation to provide a P.P.I, type display. The mid-band frequencies of adjacent frequency-selective circuits are preferably separated by their band-width. The selective circuits may constitute their own indicators; for example, a system of tuned reeds may be used. In a preferred embodiment, the spectrum of beat frequencies obtained is shifted by means of a local oscillator to a higher frequency band and is then applied to a set of crystal resonators which are arranged in a straight line in order of frequency with their optical axes parallel to one another and perpendicular to the line of the crystals. Polarised light is passed along the optical axes and thence through an analyser, which extinguishes the light from all except excited crystals wherein there are rotations of the plane of polarization. The light may be arranged to fall upon a fluorescent screen and the line of crystals rotated in synchronism with the aerial. In this case, ultra-violet light may be used. Alternatively the light output may be scanned by a photocell, the output from which is applied to a cathode-ray tube to provide a P.P.I, display. In a modification the outputs of the frequency selector are applied to an array of lamps. Alternatively the outputs of the selectors may be scanned by a moving mechanical member and thence applied to a cathode-ray tube. The Provisional Specification also describes systems wherein the line of indications is not rotated, so that an intensity-modulated range trace is obtained. By scanning such a trace with a photocell and applying the output to a cathoderay tube, a type-A display may be produced. Specifications 620,568 and 621,846 are referred to.

Title: Sewerless recirculating toilet and human waste storage system
IPC: C02F3/00
Filed: 1974-12-19
Abstract: 1490734 Recirculating flush closets MONOGRAM INDUSTRIES INC 19 Dec 1974 [27 Feb 1974] 27254/74 Heading E1C In a recirculating flushed closet, waste 18 from one or more commodes 11 is flushed into a sealed long-term storage tank 16 by a quantity of a liquid 21 having a specific gravity less than water (e.g. a clear mineral oil), the bulk of the flushing liquid 21 being stored in the tank 16 floating on the waste 18 to form a sealing layer and exclude oxygen from the waste, thereby preventing aerobic activity. Some anaerobic activity occurs but this stops as the pH rises in the methaneforming stage due to the ammonia content. The waste 18 is thus virtually unchanged as it is stored and may be removed (say once a year) for disposal or for recovery treatment. Preferably a small amount of waste 18 is left in the tank. After each flush-as by operation of a handle 13 on a cistern 12-the waste/oil mixture flows into tank 16, preferably down a ramp 19, and after a few minutes settles with the flushing liquid (oil) 21 on top of the waste 18. When a pump 24 is energised (e.g. on actuation of handle 13, or on rise of a float 22) a portion of the liquid 21 is withdrawn from tank 16 through a screen 23 on the float 22, is purified in unit 25, and delivered to the cistern 12, there always being some liquid 21 left in the tank 16 to form the oxygen-sealing layer. The purification unit may comprise (in series) (a) an undisclosed coalescer which removes suspended solids and water particles; (b) an adsorbent filter, such as Fullers earth, which removes any remaining water; (c) a chlorine bath; (d) a second adsorbent filter, such as activated charcoal, which removes dissolved contaminants. It is stated that (a) the cistern 12 may be omitted and the handle 13 be provided on the commode bowl; (b) the bowl may be dry-i.e. have no trap 14a and no residual liquid 21.

Title: A new or improved method of and apparatus for drawing sheet glass
IPC: C03B15/02
Filed: 1928-09-24
Abstract: 313,821. Haddan, P., (Virginia Plate Glass Corporation). Sept. 24, 1928. Drawing.-Relates to apparatus for drawing sheet glass and to means for applying an outward pull to the edges of the sheet in order to maintain its width. According to the invention, the apparatus comprises an elongated drawing-pot having pockets or recesses formed in its upper sides at both ends and extending outwards beyond the drawing-points or corners of the pot, and a bait bar of such a length that its end rests in the recesses when it is lowered on to the pot at the commencement of a draw. The pot may be a separate receptacle or it may be connected by a passage 6, Fig. 2, with a tank furnace 7, so that molten glass flows constantly into the pot and is kept with its surface approximately level with the upper edge of the pot. The end walls 8 are rounded and are provided with vertical guiding-grooves 9. Pockets 10 are formed in the end walls in communication with the grooves 9, and these pockets, which are filled with glass when the. pot is in use, receive the ends of a bait bar 12, Fig. 1, when it is lowered. The bait is preferably constructed with a slot in its underside. and means are provided whereby air may be withdrawn from its interior in order to draw the glass into the slot. When a draw is being made, the edge of the glass sheet 13, Fig. 4, will be formed in the grooves 9 and the sheet will draw off the upper corners 11. Because the bait is larger than the distance between the corners 11, the edges of the sheet are pulled outwards and the tendency of the sheet to become narrower as the draw proceeds is counteracted.

Title: Improvements in and relating to the production of aldehydes
IPC: C07C27/22
Filed: 1947-10-13
Abstract: Aldehydes are obtained by reacting an olefine, carbon monoxide and hydrogen at 90 DEG  to 180 DEG  C. and a superatmospheric pressure of less than 300 atmos., in the presence of metallic cobalt substantially free from other catalytic materials or activators, the molecular ratio of hydrogen to carbon monoxide being from 3 : 1 to 6 : 1, preferably in close proximity to 3 : 1.  With ratios below 3 : 1 increasing quantities of paraffin hydrocarbon corresponding to the olefine are produced together with other oxygenated products, and the yield of aldehyde falls.  The catalyst may be supported on, e.g. kieselguhr, pumice or alumina or may be fluidized.  Metallic cobalt is the preferred catalyst. Olefines instanced are ethylene, propene and their dimers and trimers and especially butenes and their dimers and trimers, such as di-isobutene and tri-butenes.  In examples, di-isobutene is reacted with a mixture of hydrogen and carbon monoxide in a molecular ratio of (1) 3 : 1 and (2) 5 : 1, at 130 DEG C., and 250 atmos. pressure, in the presence of metallic cobalt, to give varying quantities of nonaldehyde and unreacted di-isobutene, together with small quantities of octane, condensed products and cobalt compounds.  A similar experiment with di-isobutene and a hydrogen: carbon monoxide ratio of 2 : 1 is given to illustrate the fall in yield of nonaldehyde and increased yield of by-products as compared with the reactions of the two examples. In the Provisional Specification it is stated that the molecular ratio of hydrogen to carbon monoxide must be greater than 1 : 1, and that a solid catalyst containing a metal which under the conditions of the reaction forms a carbonyl, may be used.
