Patent GB-892306-A (GB)
Title: A pipe microphone
IPC: H04R1/08
Filed: 1960-03-10
Abstract: 892,306. Microphones. SONY CORPORATION. March 10, 1960 [Sept. 7, 1959], No. 8551/60. Class 40 (4). In a microphone comprising a plurality of telescopically connected acoustic pipes so arranged that an upper pipe fits outside a lower one, a cap containing an acoustic resistance is connected to the uppermost pipe while a microphone which also contains an acoustic resistance is connected to the lowest pipe. The cap 7 (Figs. 1 and 2, not shown), has a diameter of between 18 and 22 mm. so as to make the best use of the diffraction of the sound in the vicinity of the cap in order to raise the high-frequency response. The cap contains resistance in the form of a felt or silk layer sandwiched between two wire netting members, and is mounted on the upper movable acoustic pipe 1. Movable pipe 1 (inner diameter 6-8 mm.) slides over a lubricated fixed pipe 2 (thickness 0.3 mm.) and is frictionally held in any position by the nut 9 which compresses a rubber ring 4<SP>11</SP> against the movable pipe, the small difference in diameter of the pipes effectively eliminating sound reflection at the junction. A further tube 3 attached to the base 8 of the instrument provides a rigid support for the lower pipe and also serves as an acoustic shield therefor. The transducer unit T (Fig. 3), is sealed into enclosure 5 and consists of a moving coil 15, type microphone having a diaphragm 14. A felt pad 16 sandwiched between perforated metal plates 17 provides a damping means for the diaphragm and also forms a further acoustic resistance which together with the resistance in the cap tends to eliminate standing waves in the pipes. Fig. 5 (not shown), indicates various curves obtained, with and without, the acoustic resistances and shows one curve for a microphone of this type which is substantially flat between 40 and 10,000 c.p.s.

Filed: 1917-06-15
Abstract: 116,168. Adams, G. C. June 15, 1917. Hiring telephones; coin action, mechanical-connexion and multiple-coin.-In an apparatus adapted to receive coins of different values and to transmit corresponding signals to the Exchange, there is a separate hand-operated plunger 11, Fig. 1, for each value of coin, and these plungers are adapted to rotate a toothed disk 31, Fig. 5, controlling contacts 32 in the circuit of a buzzer 33 through one, two, three, or four teeth respectively, according as a penny, threepenny piece, sixpence, or shilling is inserted. The plungers 11, one of which is shown in Fig. 1, are provided with reduced inner ends and work through apertures in a plate 14, which is mounted on a stud 16 by means of a slot, and serves to lock the other plungers against movement when one is pressed in. Each plunger operates a spring-controlled lever 23 carrying a driving-pawl 28 engaging a ratchet 25 on a spindle 24, which is connected through a coiled spring 29, Fig. 8, with a barrel 30 bearing the disk 31 controlling the contacts 32. Adjustable screws 27 determine the normal positions of the spring-controlled levers 23. A fly 34 may control the speed of rotation of the barrel and disk 31. Forward movement of each plunger is limited normally by a spring-controlled detent 17, which projects into the path of a pin 18 on the plunger, but the inserted coin projecting up from a slot in the plunger moves the detent aside, a second pin retaining the detent in the displaced position when the coin passes clear. Small coins fall through a slot 12 in the casing into a return shoot 13. If a plunger has not been pushed in sufficiently far to rotate the ratchet 25 to the full extent an:l to permit the discharge of the coin, the plunger is locked against a second inward movement until the signalling operation is completed by a lever 41, which is raised into the path of a pin 42 on the plunger; the lever 41 is controlled by a floating plate 37, Fig. 8, operated by a spring 36 mounted on the barrel 30 and carrying a projection 35<a> which co-operates with a notch 34<a> in a plate 33<a> on the spindle 24.

Title: Apparatus for covering golf balls
IPC: B29C43/18
Filed: 1962-03-08
Abstract: 994,265. Covering golf balls. L. F. MUCCINO. March 8, 1962 [March 8, 1961], No. 9036/62. Heading B5A. A golf ball centre is covered by picking it up in a holder, measuring its diameter by a sensing device, placing it concentrically in a hemispherical mould half containing resin, holding it in this position until the resin is partially set, then applying the other mould half, also filled with resin. The apparatus is mounted on an annular plate 1 which is rotated intermittently stopping at various operating stations (Fig. 1). At the first operating station (Fig. 2) the centre is picked up by a vacuum holder 12 on the end of a quill 14 which can be slid through a support 15 by means of a cam and lever arrangement as shown. At the second station resin e.g. a urethane polymer, is metered into the mould half 4a by a meter 40. At the third station (Fig. 9) the diameter of the centre is measured. The holder 12 has an arm 31 with three stops 32, 33, 34. When the holder is lowered it is stopped by stop 32 and at the same time stop 33 closes the switch 52, thus starting an electric motor which rotates the sensing member 46, which is screw threaded, to move it towards the centre. When this contacts the centre the switch 53 is opened and stops the motor, the movement of the member 46 being a measure of the diameter of the centre. The motor also adjusts by means of gears turning a bar 67 a screw threaded stop 34 which is used at the fourth station to position the centre in the mould. The centre is held in this position for several stations until the resin is partially set and is then released. The other mould half 4b is filled by a resin meter 72 and the half 4a is placed on top. The whole mould is then inverted and pressure is applied by the holder 12. The mould is then clamped and removed from the apparatus, the golf ball being removed from the mould in the usual way when the resin has set.
