Title: Process for the production of fi hybrid soybean seed
IPC: A01H5/10
Filed: 1975-03-26
Abstract: 1479824 Production of F 1  hybrid soybean seed PFIZER Inc 26 March 1975 [29 March 1974] 12775/75 Heading AlE A process for producing F 1  hybrid soybean seeds comprises growing a first parent soybean plant population, which will yield small seeds after self-pollination, in spaced apart alternate rows with a second population, which will yield large seed if self-pollinated. The first population tends to be cross-pollinated by the second population, since self-pollination is suppressed as this first population is chosen for it characteristics of an exposed floral stigma 20, anthers 22 which shed pollen only after the flower opens, and partial male sterility, whilst the second population is chosen to have characteristics as above, except that the anthers produce more, and not less, viable pollen than normal plants. Insects cross-pollinate the first (female) population plants with pollen from the second (male) population, to yield intermediate sized F 1  hybrid seed. All the seed from the first population is collected, and separated by weight or size differences into the smallest seed, resulting from any unlikely self-pollination, which is rejected, and the rest, resulting from cross-pollination is the desired F 1  hybrid seed. The largest seed from the second, selfpollinated, population may also be collected for non-planting purposes. The first population may also contain a recessive genetic marker, absent in the second population, such as a distinctive penduncular pubescence 18 colour or petal 11, 12, 14 colour, which shows up in progeny of the smallest seed and is absent in progeny of the F 1  hybrid seed. Thus the purity of the sieved seed can be tested with respect to F 1  hybrid content, by growing a sample of the saved seed and recording the incidence of the genetic marker, possibly by using a photoelectric cell. If the incidence is unacceptably high, then further screening of the seed is done and up to 95% purity of F 1  seed can be attained. Suitable plants for the two parents are derived from plants located by examining large populations of existing varieties for each of the two sets of required characteristics and are bred by known techniques into homogenous stable strains, which may also show resistance to disease etc. Before planting seed to grow the parents,. it is inocculated with nitrogenfixing bacteria. The F 1  hybrid plants may be allowed to selfpollinate to generate seed for growing F 2  hybrid plants.

Filed: 1918-08-07
Abstract: 130,761. Brown, H. Aug. 7, 1918. Cooking-stoves.-A stove of the kind wherein the cooking is completed by residual heat in the stove after the supply of the heating-agent is cut off, consists of one or more insulated casings provided with a ventilating-aperture and containing a heat-retaining " hot plate." Fig. 1 shows a stove consisting of three dome-like covers 4 containing a " hot-plate " 1 and a " thermostat " 11 controlling an alarm 14; in a modification, the " thermostat " controls valves for closing the ventilating-aperture, the gas &c. cut-offs, and the air-admission apertures. The stove shown is heated by a gas burner 3, but may be heated electrically or otherwise. When the oven is hot enough, the ventilating-aperture 7 is closed by a valve 8, and the heat supply, which is turned on by hand, or automatically by clock-work or the like, is cut off by hand or automatically. The " thermostat " consists of a closed tube containing a readily-fusible piece of metal 12, and is supported on a pivot 9 and a stop 18; when the desired temperature is reached, the metal melts and runs into the other end of the tube as it tilts. This movement of the tube closes the switch 15 and rings the alarm bell 14, and may also cut off the gas in the pipe 16 or other source of heat. The tube 11 is afterwards reversed and supported on the pivot 9 at the other notch 7. The cover 4 is preferably dome-shaped, and its walls may be of polished metal. It may be enclosed in a cover 19 containing a solution of salt, such as sodium acetate, which gives out heat on crystallizing. A third cover 20 packed with non-conductor 20x may be provided. Fig. 2 shows a stove wherein the " thermostat " 11 closes the ventilating-aperture 9 by means of a valve 8, the gas cock 25 by means of a rod 26, and the air-inlet apertures 23 bv means of a hit-and-miss valve. The tube 11 containing the fusible metal may be slipped by hand into an insulating-cover so as to control the radiation of heat from it.

Title: Improvements relating to powder metallurgical processes
IPC: B22F5/10
Filed: 1946-05-01
Abstract: 611,466. Making turbine blades; powder metallurgy. GENERAL ELECTRIC CO., Ltd., and JENKINS, I. May 1, 1946, No. 13159. [Classes 83 (ii) and 83 (iv)] In a method of forming ducts, holes or voids in a body of sintered metal powder, particularly cooling ducts of very fine bore in gas-turbine blades, suitably shaped formers at least partly metallic, are introduced into the powder before the final sintering process, the formers being composed of, or convertible into a material fusible at a temperature lower than the final sintering temperature. In particular applications, pure tin wires of 0.015 in. diameter and 4 in. long were pressed in molybdenum in a mould 4 in. by # in. under 35 tons per sq. in. pressure to produce a bar approximately <SP>5</SP>/ 16  in. thick, the bar then being heated in a hydrogen atmosphere to above the fusing point of the tin. Cadmium wires of a similar size were pressed into a compacted bar of an alloy of mainly chromium and cobalt, the compact being held at the temperature of the boiling point of cadmium for some hours in a hydrogen atmosphere before the final sintering process. The choice of former material is governed by the conditions of heat treatment and composition of the main body, cadmium being stated to be suitable when heat treatment takes place in an oxidising atmosphere. The former may be of complicated shape and either solid or hollow. In addition to tin and cadmium, zinc or indium may be used for the former. In the manufacture of ducted gas-turbine blades in accordance with the invention, a number of wires of, for example, cadmium would be disposed in the powder body running longitudinally along the blade. Specifications 452,503, [Group II], and 573,740 are referred to.

Abstract: 777,889. Motor vehicles. ALBEE, W. H. May 6, 1955 [May 17, 1954], No. 13171/55. Classes 79(3) and 79(5). [Also in Groups VIII, XXXII and XXXIV] A vehicle comprises an axially - elongated flexible - walled, fluiddistensible roller 11 of symmetrically crowned shape for supporting a transportation load applied to its outer surface, and revolvable means 16 journalled on a structure 15 for applying the force of the load to the roller 11, and means 13, Fig. 5, associated with the structure 15 for maintaining fore-andaft alignment of the means 16 and the roller 11, the means 16 comprising roller-contacting elements in succession along the axis of the means 16 of axially-graduated peripheral speeds corresponding to the axially graduated peripheral speeds of the respective elements of the roller 11. As shown in Fig. 1, the vehicle has a single roll 12 journalled in radius arms 44 pivotally mounted on a frame 39 which is rotatable by steering gear 40, 41, 37 about an inclined axis 35. The rear of the vehicle is supported by two rolls 11, 11, mounted side-byside. Each roll 11 is journalled in the arms of a yoke 13 which is pivotally mounted on a frame 15 rigid with the vehicle frame. Journalled in the frame 15 are four of the rolls 16, each of which carries a sprocket 17 which is driven by a chain 18 which also passes over an idling sprocket 19 and a drive sprocket 22. The latter is chain driven from a conventional type of rear axle 23. The profile of the roll 16 is suitably curved so as to result in a minimum degree of slip between itself and the roller 11. The roll 16 comprises a metal shell 16b and a surface layer 16d which may be of brake lining material, emery powder, or abrasive particles, retained in a synthetic plastic material. The surface is formed with circumferential grooves 16e. The roller 11 comprises a rubber bag mounted on a hollow shaft 11a journalled in the yoke 13. The bag may be inflated via a valve 11e mounted in the end of the shaft 11a. An intermediate peripheral band, only, of the roller 11 is coated with anti-friction material. The surface area of the roller 11 in contact with the ground, may be increased by the actuation of a levercontrolled cable 33 connected to the yoke 13. The latter is formed with a skid surface 25 adapted to engage ground obstacles 24, Fig. 3. The skid surface 25 is replaced by rollers 43 journalled on the arms 44, in the case of the front suspension. The roller 11 may be partially filled with liquid in order to provide increased traction, or for submergence in water. In the construction shown, load-supporting rolls 16 are mounted in the frame 39 of the front suspension in the same way as they are mounted in the frames 15 of the rear suspensions, but these rolls are not driven. Due to the axis 35 being rearwardly inclined, increased compression is placed on the end of the roller 12 on the inside of a curve, Fig. 8 (not shown). The idler sprocket 19 may be mounted on a chain tightening slide (not shown). Specification 743,997 is referred to.

Abstract: 215,963. Trier, V. A. May 17, 1923. Vibration-dampers.-In shock-absorbers of the friction type in which the friction between the friction elements is automatically increased in a progressive manner throughout the relative movement of the elements, three or some larger odd number of friction discs are each freely interposed between two metal discs respectively carried by the arms, the friction discs and metal discs being arranged alternately in such a manner that relative movement between the free ends of the arms, the alternate ends of which are connected together, causes relative rotation between the discs. Fig. 2 shows three friction discs D interposed between metal discs A<1>, B' respectively attached to the arms A, B. A pivot pin E is locked in relation to the arm A and carries a nut M locked in relation to the arm B by means of a spanner arm N. The nut M bears on the discs B through a star spring J. Relative movement of the arms R, B therefore automatically varies the pressure between the friction discs and the metal discs.

Abstract: 1478841 Film transport systems R FIELD K VINCENT and H NADIG 20 June 1974 [20 March 1973 21 June 1973] 13410/73 and 29470/73 Heading G2E A film transport system accurately positions frames of a film strip at a gate aperture by comparing the actual position, as detected by a sensor, with a pre-programmed position, generating an error signal to correct the motion of the motor shaft driving the film. The sensor may detect the location of a perforation edge, or coded marks along the film strip. Alternatively an encoder may be attached to the driving motor shaft, whose angular position is detected by the sensor. The sensors read the precise position in the film gate, which reading is fed back to a central electronic network which compares that position with a preprogrammed velocity/position curve. The position or velocity of the film frame is thus continually corrected. The shutter comprises a segmented disc (7), Figs. 1 and 2 (not shown), and it may be controlled electronically in a manner identical to the film drive. Both the film drive and shutter drive are controlled and co-ordinated by a central timing circuit, as shown in the block diagram of Fig. 3. The description is amplified in some detail in the two Provisional Specifications.

Abstract: 332,921. South Metropolitan Gas Co., and Carpenter, C. C. April 30, 1929. Producers.-To diminish loss of fuel during the clinkering period of a producer, natural draught is replaced by a suction so controlled that the draught is kept above the minimum requisite for avoiding dangerous escape of hot gas through the clinkering doors. Good quality gas is thus made during the clinkering period. The gas off-take may be above the freshly charged coke so that the gas is reduced in temperature before it enters the fan, the fuel is preheated and tar and moisture removed from it. The suction fan may be operated not only during the clinkering period but more or less continuously, so that a proportion of the hot producer gas may pass through the green coke. Specification 305,764 is referred to.
