Title: Fitting a prosthetic device for providing correction of auditory deficiency
IPC: H03G9/02
Filed: 1974-04-09
Abstract: 1472902 Testing and treating hearing J L HOLMES 9 April 1974 [12 April 1973] 47912/76 Divided out of 1472901 Heading H4J The hearing of a partially deaf person is tested by providing the subject with sound output from a test device including filters in the range of acuity deficiency having the person indicate the better perception of continuous discourse when the device is operated with a first filter network and subsequently operated with a second filter network and thereby determining the more suitable filter network for the person. Apparatus for testing a patient's hearing comprises a source 40 (Fig. 1) providing a pure tone of gradually increasing frequency from approximately 200 Hz to 10,000 Hz, pulsed at two to ten pulses per second by a pulser 41. The patient controls the intensity of the tone by a switch 43 to cause the intensity to decrease to a just-inaudible level, immediately after which he causes the tone to increase to a just-audible level, repeating this procedure continuously as the tone frequency increases gradually. The results are recorded in ink on semi-log paper in an XY recorder 46 and provide data regarding absolute threshold for pure tone. To determine auditory discomfort levels the patient uses switch 43 to control tone intensity, causing the intensity to increase to a distinct discomfort level, after which he causes the intensity to decrease to a tolerable level. This procedure is repeated as the tone frequency increases gradually. The results are again recorded in the XY recorder 46. From these two operations a general filter network 54, 55, ... 56 (Fig. 2) is initially selected to provide generally complementary amplification in a master hearing aid 49. The master hearing aid 49 (see Fig. 1) is now coupled in the "sound field" mode and recorded speech is fed through a microphone 48. The patient then decides which filter of a pair gives better perception of speech. By using forced-choice paired comparison the "best" condition is determined for each parameter. The "calibration" mode (switch 51) of Fig. 1 is used to record on the XY recorder 46 the curve from which the appropriate filter arrangement is determined. The patient is then coupled with a hearing aid having its parameters adjusted (e.g. the adjusted master hearing aid 49) and unless a continuous discourse test is satisfactory the forced-choice paired comparison is repeated. The chosen filter arrangement is then incorporated in a system such as that shown in Fig. 1 of co-pending Specification 1,472,901. In a variation a combination of the filters 54, 55 ... 56 is selected in a single test, each filter being separately attenuated by unit 57 (Fig. 2). The forced-choice paired combination then involves filter combinations.

Filed: 1970-10-13
Abstract: 1326409 Travelling ends down detector PARKS-CRAMER CO 13 Oct 1970 [14 Oct 1969 3 June 1970] 48685/70 Heading D1F An ends down detector is arranged to be transported by a travelling service unit, e.g. a pneumatic cleaning unit along a textile machine, e.g. a spinning frame. The detector, e.g. a photo multiplier tube 21 feeds the logic circuit of Fig. 2. The logic curcuit comprises a unijunction transistor 22 which gives a pulse when capacitor C3 is charged via variable resistor R1, this sequence occuring cyclicly over a predetermined time interval. When the detector 21 passes a station where an end is present a pulse is communicated via capacitor C1, amplifier 25 and transistors 26 and 23 which discharges capacitor C3. Thus if an end is traversed prior to the unijunction transistor 22 being triggered no pulse is emitted. The circuit is preset prior to traversal of a machine by a signal received from a detector 31 and amplified by circuit 30 which discharges capacitor C3. The detector 31 is responsive to a reflective member 41, Fig. 5, mounted on the track of the service unit. The reflective member 41 is illuminated by a light source 40, through a partially reflective member 42 and a lens 44; the light is then reflected back to the detector 31. In an alternative embodiment Figs. 6 and 7 (not shown) reflective rods (140) in line with the ends of yarn give a stronger signal from a detector (121) than does an end, and this feeds a second circuit (130) via a blocking resistor (R11) to discharge a capacitor (C31) which corresponds to C3 in Fig. 2. Specification 1,267,701 is referred to.

Abstract: 1,076,189. Clocks and watches. R.W. REICH. Dec. 17, 1963 [Jan. 7, 1963], No. 49750/63. Heading G3T. An electric timepiece driving arrangement is of the kind in which a driving coil A in circuit with an exciting coil E co-operates with a magnetic member to impulse a balance 10, 12. The magnetic means includes first and second magnetic portions displaced by 180‹ about the axis of the balance. The first magnetic portion interacts with the exciting coil and the second magnetic portion is arranged so that it cannot produce an exciting pulse in the coil E. As shown, the exciting coil comprises two distinct coils so connected that a resultant exciting pulse is produced by the magnets 16, 18, 22, 24 at one end of a diameter of the balance. At the other end, two magnets 14, 20 are impulsed by the driving pulse in coil A. When the balance has rotated through 180‹ from the position shown, no resultant exciting pulse is produced. In another embodiment, Fig. 1 (not shown) a bar magnet of the balance is pivoted at its centre. This magnet has a free or effective pole at one end only. The other end is recessed and a small reversed magnet inserted to neutralize the pole at that end. In another arrangement, Fig. 3 (not shown) the exciting coil (E) is of larger size than the driving coil (A, not shown) at the opposite end of the balance. In the position illustrated, an exciting pulse is produced, and the driving coil co-operates only with the inner pair of the concentrically arranged magnets adjacent the coil to impulse the balance. When the balance has rotated 180‹ the larger coil E co-operates with both pairs of the concentric magnets and no resultant exciting pulse is produced. In another form Fig. 5 (not shown) the magnet with the neutralized pole is positioned inside box-shaped exciting and driving coils (E, A). The exciting coil E is positioned intermediate two separate portions of the driving coil (A). A similar magnet may co-operate with coaxially arranged exciting and driving coils of different diameters, Fig. 6 (not shown), or be placed within a ring-shaped member carrying the coils, Fig. 4 (not shown).
