Title: Improvements relating to moving coil loud speakers
IPC: H04R9/02
Filed: 1933-03-24
Abstract: 413,819. Loud-speakers. WILLSON, H. C., Walton, Bockminster Road, Wolverhampton. March 24, 1933, Nos. 8964 and 20985. [Class 40 (iv).] In a moving coil loud-speaker, the diaphragm is supported by a member disposed on the side of the diaphragm remote from the field magnet and does not depend for its support on a member on the same side of the diaphragm as the body of the magnet, the diaphragm supporting member engaging with the central core of the magnet or with a member attached thereto along axially directed surfaces formed respectively on the supporting member and on the central core or member attached thereto so as to ensure that the diaphragm and coil former are accuratelypositioned with respect to the field magnet. Fig. 1 shows a construction in which a cone 7 carrying a coil 8 has its outer edge 11 cemented to the rear of the rim 10 of a supporting member 6 having a central hub 5 into which a reduced projection 4 on the centre magnet core 1 is adapted to fit and be secured by a nut 12. A centring spider 16 is secured at 19 to the cone 7 and is clamped against the hub 5 by a washer 18 and nut 17. A cover 20 for the rear of the cone is bolted, riveted or cemented to the rim 10 and carries a transformer 21 or a terminal plate. The parts are assembled as follows. The cone 7 with the coil support 9 and spider 16 is placed on a cylindrical mandrel 23, Fig. 4, the middle portion of which is a sliding fit within the support 9. The mandrel is formed with a knurled portion 24, a central spigot 25 of similar length and diameter to the projection 4 and a projecting portion 26 adapted to be held in a chuck to allow the cone assembly to be rotated while the edge of the cone dips in a bath of adhesive. The diaphragm assembly still on the mandrel is then placed on the member 6, the spigot 25 passing into the hub 5 and a light cardboard ring 27 is placed on the edge of the diaphragm to prevent it sticking to a press in which the cone and its support are then placed. When the adhesive is dry the mandrel is withdrawn, the washer 18 and nut 17 are dropped within the former 9 over the threaded portion of hub 5 and the nut 17 tightened by the pin spanner shown in Fig. 5. This spanner has a handle 30, a body portion 28 fitting in the support 9 and provided with pins 31 which fit recesses in the nut 17 and a spigot 29 corresponding to spigot 25 and projection 4. The assembly is completed by fitting the cover 20 to rim 10 and securing the magnet by screw 12. Fig. 6 shows a modified construction in which a sheet metal member 6 is employed and the integral hub 5 is replaced by a composite hub consisting of bush 32 and nut 33. Shims 41 between the end of bush 32 and the abutting end 39 of the central core 40 ensure that the support 9 is accurately located axially with respect to the air gap. In this construction, the chassis or cover 43 is bolted to the magnet 2, an annular space being left between its outer cylindrical portion 44 and the rim 45 of the member 6, which space is filled with a felt ring 46.

Title: Improved automatic gramophone
IPC: G11B17/02
Filed: 1940-05-24
Abstract: 541,156. Gramophones. SLATER, G. May 24, 1940, No. 9160. [Class 40 (ii)] An automatic gramophone comprises a number of wheels 10 for supporting and driving a record dropped thereon from a magazine and adapted to be swung out about pivots 13 to drop the record after it has been played, a pair of pick-up devices 8, 9 being provided to engage opposite sides of the record. Magazine.-The records are stacked over a shoulder 1a on a central stem 1 and are released one at a time by a finger 2 acting on the edge of the record when rocked about a pivot 2a. Driving mechanism.- The records resting on the wheels 10 are driven by one or more of these wheels engaged by a friction pinion 48 connected to a motor by a flexible shaft. Each wheel is carried by a bracket 11 pivoted at 13. The several brackets are interconnected by links 14, 15, 16 and are adapted to be moved and held in operative position by the engagement of a lever 45 with a tappet 44 on the link 16. When the record has been played, the lever 45 moves away and allows the brackets 11 to swing out by gravity about the pivots 13 to drop the played record. Pick-up devices.-Each pick-up arm 8 or 9 is mounted by an horizontal pivot 23 on an arm 21 and can be raised and lowered about that pivot by means of a rod 25. The arm 21 is carried by a hollow spindle 26 rotatably mounted in a bracket 22 for lateral movement of pick-up arm. Controlling mechanism.-The operation of the gramophone is controlled by means of a pair of cam devices 17, 18 driven alternately through ratchet controlled clutches 49, 50 from a shaft 3 coupled to a motor through worm gear 4. These cams control the record releasing finger 2 and lever 45, the pick-up arms 8, 9, and a reversing switch 36 by means of the various mechanisms 61, 20a, 31, 33, the reversing switch being necessary because the record must be rotated in one direction for playing one side by one pick-up and in the other direction for playing the opposite side by the other pick-up.

Title: Improvements relating to thermographic machines
Inventor: CRANE DENIS PERCY
IPC: G03B27/30
Filed: 1969-02-22
Abstract: 1291855 Photo-electric temperature sensing FRANK R FORD Ltd 19 Feb 1970 [22 Feb 1969] 9644/69 Heading G1A [Also in Division G2-3] In a thermographic copying machine, between rollers 14, 15 Fig. 1 of which passes temperature sensitive paper sheet and an 'original' sheet to be copied, the mark/space ratio of current pulses fed to an infrared lamp heater 24 within roller 14 is controlled to maintain substantially constant. The output temperature of the heater and hence also the heat applied to the paper. Alternatively the machine may be used to stick sheets together. A thermistor Th on a bracket 28 senses the surface temperature of the roller 14 and picks up radiant heat from the lamp transmitted through a hole 25a in a reflector and through the transparent wall of the roller. Alternatively the sensor may be within roller 14. The temperature sensed by the thermistor therefore corresponds to that experienced by the lateral area of the sheets passing under a slot 27 in the reflector. SCR1 Fig. 3 is controlled in dependence upon the impedance of the thermistor whereby to control the average D. C. through heater lamp R1. A feeler member 37 senses the entry of sheets into a passage 11 and closes a switch S1 which energizes a relay coil 4. Relay contact A1 is thereby caused to change over from the position shown in Fig. 3. Thermistor Th controls the conductivity of a transistor T 1  and hence also the charging time of a capacitor C 1  charged via a diode D 1  and the transistor T 1 . A uni-junction transistor UJT 1  is triggered, when the voltage in C 1  reaches the necessary value, and applies a firing pulse to SCR1. The delay angle of this pulse is dependent upon the magnitude of the charging current of C 1  and the time it takes to charge which in turn is dependent on the resistance of Th, The lower the temperature sensed the earlier the firing pulse of SCR 1  will occur and the longer the conduction periods of the SCR and heater, and vice versa. A resistor R 10  is preset to enable the magnitude of compensating effect of Th to be varied to suit operational requirements. Time delay means including C2 ensure that heating will continue after the switch S1 opens on passage of the trailing edge of the sheets. Instead of controlling the lamp current a shutter may be moved across the lamp, the shutter being controlled by a sensor in the form of a bimetal strip and directly or indirectly coupled mechanically thereto.

Abstract: 472,413. Combined gaseous and solid-fuel stoves. RADIATION, Ltd., YATES, H. J., and STRINGER, W. L. April 3, 1936, No. 9867. [Class 126] In a domestic oven heated either by the hot gases from a solid fuel fire or by those from a gas burner as required, the burner d is arranged beneath the lower edge of the front of the oven. The hot gases from the burner d, which is enclosed in a hinged cover i, pass through a slot e into the oven a, and thence through pipes and openings p into a hot-plate chamber k, which communicates through an opening p<1> with the chimney. A flap f, which closes the slot e when the door c is open, is closed when the door is shut by engagement of the door with the tail-piece h. The door also controls a valve controlling the burner. The openings p, p<1> are controlled by plates n pivoted about their lower edges. Lugs r with inclined sides project from the plates n through openings in a slidable bar q which is moved by a pinion and toothedsegment device to cause the plates n to open and close. The rod carrying the toothed segment actuates a second valve controlling the burner a. When the grate b is in use, the hot gases pass partly up the rear flue to the chimney opening 11, and partly through horizontal side flues 12 to vertical side flues, one of which is closed at the top and communicates through the flue 14 with the other vertical flue, which communicates with the horizontal flue 15. Side openings 17 in the plate 16 connect this flue with the space above communicating with the chimney opening. Linked dampers 19, 20 control the openings 17 and the rear flue. Some of the burner gases also pass to the flue 14. If desired, the hot gases in the oven may be discharged directly through openings 30 communicating with the front of the oven casing. Specification 174,876, [Class 126], is referred to.

Title: Optical scanner
Inventor: MORIMOTO YASUAKI
IPC: G11B7/09
Filed: 1990-01-09
Abstract: Optical scanning device with an objective lens. In a recording and/or reproducing device which reads data from an optical record carrier, e.g. a disk, by the single-beam process, the entire optical scanning device is moved in order to direct the light beam onto the data tracks on the disk. Fine adjustment solely by moving the objective lens in the radial direction, as in the triple-beam process, is not possible, because the light spot follows the movement on the two-part photodetector, causing an offset in the track error signal TE. In order, nevertheless, to permit fine adjustment by means of the objective lens, the light beam (L) which scans the data is moved by a fine drive in a direction (W) which makes an angle  alpha  to the normal (R) to the data track. The light beam (L) is reflected from the disk onto a photodetector consisting of several photodiodes (A, B, C, D), and the track error signal TE is derived from the output signals (AS, BS, CS, DS) of said photodiodes by weighted sum and difference formation. Application: CD players, magneto-optical recording and reproducing devices, video disk players, DRAW disk players.
