Title: Improvements relating to the mounting of seeds for planting
IPC: A01C1/04
Filed: 1943-06-03
Abstract: 566,893. Packing seeds. JENKINS, F. C. June 3, 1943, Nos. 8924/43 and 2572/44. [Class 94 (i)] An improved method of mounting seeds on paper carriers to facilitate sowing consists in attaching the seeds to a thin paper band which is folded into a tube to enclose the seeds, and finally it is twisted into string. Pest deterrents or plant food may be enclosed in the string. The paper 1 is led from a reel 2, Fig. 1, by guide and feed rollers 3, 4, 5 to a seed - applying mechanism 6, thence to a folding device 11, over a roller 12 through a lappet eye 13 to a traveller 14 carried by a ring 15 which rotates with a bobbin 16 on which the string containing the seeds is wound. The seed-applying mechanism is shown in Fig. 2 and comprises a roller 52 provided with rubber projections 53 for applying beads of gum or other adhesive to the band 1 as it passes over a feed roller 28. The gum is received from a roller 54 which is driven by reduction gearing from the shaft 61 of a seed-disperser 63 which projects seeds on to the band as it passes over the inclined side 93 of a hopper in which the seeds are contained. Prior to receiving the gum beads, the band may be formed with slits by a reciprocating cutting-device 32 driven by crank pins 35, 36, whilst passing between slotted support plates 43, 44. To prevent fouling of the roller 28 should the band not be fed around it, a groove is formed therein in register with the projections 53, which permits the projections to pass the roller without gumming it. The hopper 9 has a sliding plate 23 which can be withdrawn to discharge seed into a shoot 17 when a new kind of seed is required. The seed is maintained in contact with the spraying wheel 63 which rotates counterclockwise by discs 65, 66 of screw formation. The folding device, Fig. 6, comprises a flat metal support 73 with turned-over side edges 74 at its entrance end which starts the folding. Slots are cut in the walls 75 at the outlet end to allow passage of large seeds. The folded band passes over a turning bar 83 on its way to the roller 12, Fig. 1, and flanges on a roller 76 prevent the band from being withdrawn from the guides during the turning. In modified forms the device may be arranged to secure more than one seed in side-by-side relationship on the band, and, as shown in Fig. 12, for dealing with large seeds the disperser 63 may deliver to a bucket-type conveyer 78 which deposits the seeds on to a slotted fender 81. This fender may be modified by causing it to oscillate from an inclined position to a horizontal position for delivery. The machine may be fitted with known kinds of registering, controlling, printing, &c. mechanisms, and with automatic cut-off mechanism for the string.

Title: Improvements in swash-ring driving mechanisms
IPC: F16H23/06
Filed: 1939-03-28
Abstract: 526,972. Swash-plate mechanism. STINNES, H. H. March 28, 1939, No. 9620. Convention date, Nov. 21, 1938. [Class 80 (iii)] Relates to swashplate mechanism in which the transmission elements, e.g., swivel blocks 5, between the reciprocating pistons 6 and the studs 4 on the swashring 3 have lateral play in the piston crossheads. According to the invention, the clearances 8 at the ends of the swivel blocks when in mid-position, e.g., I or IV, are so dimensioned that the lateral motions each side of the piston axis amount to one quarter of those total lateral motions which, in the case of restilinear guidance of the ring, with a similar disc angle and ring diameter, would occur for a stud displaced 90 degrees from the guided stud. The lateral throw may be restricted by the walls of the cylinders, e.g., as at positions II and VI, or the swivel blocks may project through an aperture in the wall and abut a stationary structure outside, e.g., a rail or the cylinder casing. The ends of the blocks conform to the part with which they abut.

Title: Apparatus for testing microphones
IPC: G03B17/42
Filed: 1941-07-31
Abstract: 550,877. Converting. FOUNTAIN, Ltd., G. R., HOULGATE, H. J., and MARKS, P. D. R. July 31, 1941, No. 9737. [Class 38 (ii)] [Also in Group XXXIX] Apparatus for use in testing microphones comprises a sound generator coupled to a tube open at the other end, the open end being of small diameter compared with the wavelength of the sound so that a spherical wavefront is emitted. The apparatus provides a small sound-emitting area close to the microphone the effect being similar to that of the mouth. In the apparatus, shown a loud-speaker unit 1, which may be of the type described in Specification 519,625, [Group XXXIX], is coupled to a tube 2 of small diameter compared with the wave-length of the sound frequency used; for example having an inside diameter of 7/10 inch for a frequency of 400 cycles per second. The length of the tube is adjusted so that resonance occurs with a velocity antinode at the open end. in which circumstance a blast of air is produced simulating that produced by the mouth at the beginning of most words. The microphone 7 to be tested is held adjacent to the end of the tube in an open supporting member 8 adjustably clamped on the tube. The speaker may be driven from an oscillator operating at the desired frequency the input being adjusted until the microphone output, as measured by a voltmeter across an output load, is normal, or the microphone output being measured for constant sound strength. Instead of providing a separate oscillator, the apparatus may be made self-exciting by operating the speaker from an amplifier, to which is connected a microphone opposite an aperture in the tube wall situated at a pressure antinode. Alternatively, a microphone 21 of low acoustic impedance may be coupled to the tube through a high acoustic resistance such as a capillary tube 22, or a small piezo-electric element may be mounted in the tube, or a very small velocity microphone may be located at the mouth. Phase-correcting networks may be employed to bring about the required conditions for oscillation, and the selection of the desired frequency from the several frequencies at which the tube may tend to oscillate may be effected by making the response of the microphone a maximum at that frequency, or by adjusting the phase-frequency characteristic of the microphone so that only at the desired frequency is the phase correct for producing oscillation. Specification 507,183,- [Group XXXIX], also is referred to.
