Title: Hearing aid ear inserts for placing in the auditory canal
IPC: H04R25/02
Filed: 1965-07-14
Abstract: 1,119,446. Hearing aids. DANAVOX INTERNATIONAL A/S. 14 July, 1965 [26 March, 1965], No. 29783/65. Heading H4J. An in-the-ear hearing aid receiver includes a housing having an opening and a protective imperforate membrane covering the opening. The membrane may be a disc adhered over the opening. Preferably, a flexible housing 3 (Fig. 1) of the receiver 1 is sheathed in a replaceable bag 6 of latex rubber or plastics. A sound duct 2 from the receiver diaphragm leads to a sound opening 4 in the housing 3. The lower portion of the bag 6 prevents foreign substance penetrating the receiver 1 and serves as a sound diaphragm. Beaded edge 7 keeps the bag 6 tight. Different portions of the bag 6 may be of different thicknesses. Thus the side wall of the bag 6 may be thicker than the diaphragm portion. The side wall of the bag may have an annular bead to seal the bag 6 against the auditory canal (Fig. 2, not shown). A hearing aid arranged to be introduced as a whole into the auditory canal and including an amplifier has a microphone at the outer end and the protected receiver at the inner end.

In use, fluid delivered through port 76 drives piston 64 and thereby the movable portion 34. After contacting the spacer 72 further movement of the piston 64 also causes movement of the spacer and thereby the movable portion 32. The spacer 72 is fluted so that fluid delivered through port 78 can drive the piston 64 back to its initial position.

Title: Stone separating device for potato harvesting machines
IPC: A01D33/04
Filed: 1951-12-24
Abstract: 689,026. Separating solid materials. ANDERSSON, F., and ANDERSSON, G. Dec. 24, 1951, No. 30137/51. Class' 117 [Also in Group XXX] A device for separating stones from potatoes, which can either be mounted on rollers in order to be coupled to a potato harvesting machine, or which can be made as a fixed part of such a machine, comprises an endless conveyer band which receives the material to be separated and consists of a number of parallel belts 6a, 6b arranged closely adjacent one another, the belts being driven in such a mariner that alternate belts are moved at the same speed whilst adjacent belts are moved at different speeds, one or more blowers 19 causing air streams to sweep over the surface of the conveyer band substantially at right angles to the direction of movement, whereby the potatoes are blown to a collecting device and the stones remain on the conveyer and are discharged at the delivery end. Rotatably mounted in the frame 1 are shafts 2, 3, which carry the belt pulleys 4a, 4b, and 5a, 5b, respectively, the shaft 2 being driven from shaft 9 through gears 7, 8. The pulleys 4a are rigidly connected with the shaft 2 while the pulleys 4b are free to rotate on the shaft, and the pulleys 5b are rigidly connected with the shaft 3, the pulleys 5a being rotatably mounted on the shaft. A shaft 10 is driven from the shaft 2 and through an endless belt 18 and gears 14, 15, drives the shaft 3. Arranged on one side of the frame 1 are a number of blowers 19 which blow the potatoes on to the transport belt 18 which conveys them to the rear of the machine. The ratio between the different speeds of the belts 6a, 6b is arranged to be between 1: 1¢ and 1: 1¥, and since the belts are comparatively narrow a stone never remains directly located between the blowers and a potato. The space between the outer belt 6a and the belt 18 is bridged over by a plate 24, and a plate 25 serves as a stop plate for the potatoes. The belts 6a, 6b are supported between the belt pulleys on rollers which may be so arranged that the upper part of the conveyer band extends upwardly in arcuate fashion, and in order to facilitate the falling of soil between the belts each belt may be twisted on the underside of the conveyer band.

Abstract: 934,655. Indicating availability of parking space. STANDARD TELEPHONES & CABLES Ltd. Sept. 1, 1961 [Sept. 2, 1960], No. 30364/60. Class 106 (3). A vacancy indicating system for a car park comprises a ratiometer coupled to a parallel resistance network, the parking of cars changing the resistance of the network and the ratiometer responding to the resistance changes to indicate the number of vacant spaces. The position of pointer C on scale D of ratiometer A depends on the current flowing in coil B2 which is determined by the number of resistors RS1 to RSN which are inserted in or removed from the circuit by switches S1 to SN respectively, one switch being provided at each parking space and being arranged to open when the parking space is occupied. The current through coil B2 drops as more spaces are occupied until only five or less spaces are unoccupied, which number is shown on scale D. When only one of the resistors remains in circuit, relay P operates to complete a circuit for a warning light L. A resistance RF, connected permanently across the cable close to the first parking space, serves to check that no break has occurred in the cable leading to the car park. A break in the cable would cause the pointer to move to position Y.
