Title: Improvements in talking machines
IPC: G11B17/00
Filed: 1927-01-18
Abstract: 294,193. Gramophone Co., Ltd., and Buckle, H. L. T. Jan. 18, 1927. Divided on 291,480. Magazine gramophones. - Relates to automatic gramophones of the kind adapted to play a number of records in succession, irrespectively of the size of the records, and in which the distance through which the tone-arm and sound-box are moved in order to engage the starting-point of a record is determined by means operated by contact with the edge of the record to be played. According to the invention, there is provided a member which is capable of movement independently of the tone-arm or of the means for swinging the tonearm, this member being adapted to be set by contact with a record about to be played, in such a position as to control, in accordance with the size of the record, the means for swinging the! tone-arm and sound-box. The invention is described as applied to the machine described in Specification 291,480 in which, after the playing of a record, the tonearm 3 and sound-box 4 are first raised, and, after automatic removal of the played record are swung outwards by means of a lever 12. When a fresh record has been lifted from a magazine and deposited on the turntable, by means of an arm 7, the tone-arm is moved inwards by the action of a hook 18 pivoted on the lever 12, both the outward and inward movements of the tone-arm being effected by engagement of the members 12 or 18 with a post 16 projecting from an arm 17 fixed to the tone-arm. As soon as the soundbox has reached a position where the stylus is over the starting-point on the fresh record, the inward movement of the tone-arm is stopped by disengagement of the hook 18 from the post 16. The point at which this occurs is determined by means of a lever 21, which is controlled by an horizontally-movable lever 32. This is itself set to the appropriate position by the action thereon of the record as it approaches the turntable. The lever 32 carries two posts 37. 38, one at each end, and by the engagement therewith of the edge of a record, during its transference, the lever is set either to the full-line or dotted-line position, according to the size of the record. The mechanism referred to above is fully described in Specification 291,480.

Title: Displacing magnetic domains
IPC: G11C11/14
Filed: 1974-04-22
Abstract: 1450837 Magnetic storage arrangements PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 April 1974 [25 April 1973 26 Oct 1973 5 April 1974] 17436/74 Heading H3B In an arrangement for propagating a domain wall in a magnetizable layer having an easy magnetization axis perpendicular to the layer plane, a magnetic propulsive field acting upon the domain wall has a value at each instant during propagation which is less than the critical field threshold value at which a reduction in propagation speed occurs, such a speed reduction being shown to occur by an analysis in the specification. The magnetizable layer may be a thin film 1 of gallium-substituted yttrium-iron garnet, Fig. 3, epitaxially grown on a substrate of gadolinium gallium garnet and supporting a domain wall 3 formed by a gradient field H(y), Figs. 1 and 2. This field is produced by permanent magnets 4, 5 and is directed perpendicular to the plane of the film. An auxiliary field Hy produced by windings 8, 9 is directed in the plane of the film. Optionally this field may be omitted and a corresponding effect obtained by positioning the film asymmetrically with respect to the magnets 4 and 5. To propagate the domain wall a pulse producing a propulsive field Hz within the required maximum limitation is applied by a winding 6, the field being perpendicular to the plane of the film and acting in conjunction with the gradient field H(y) to move the wall from stable position A, Fig. 2, to stable position B. The Faraday effect on a light beam may be used to observe the wall displacement and to determine its velocity. The maximum velocity obtainable is influenced by the strength of the auxiliary field Hy. In a modification the pulse producing field Hz has a stepped leading edge, Fig. 8 (not shown). Fig. 9 shows an arrangement for the propagation of a cylindrical magnetic domain 13, the in-plane field Hy being provided by magnets (not shown), and the propulsive field Hz produced by an energized winding 12. The field Hz is of such strength as to contract a domain wall from a stripe to a cylinder or "bubble" 13, and for bubble propulsion acts in conjunction with a gradient field produced by a pulse source 17 connected to spaced parallel conductors 14, 15.

Title: Keyboard operated data entry devices
IPC: G06F3/023
Filed: 1972-04-17
Abstract: 1334334 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 17 April 1972 [22 June 1971] 17533/72 Heading G4H A keyboard-operated data entry device has a buffer memory fed from the keyboard, a counter identifying a data position in the buffer where an entry is to take place, means providing a scanning operation through the buffer data positions, and means for backspacing the counter. The buffer is a circulating shift register, and the counter is a column counter which is incremented as successive characters are entered from the keyboard (for eventual punching into respective columns of a punched record). A character is entered into an input/output stage of the buffer when the count is equal to that of a column ring (counter) which specifies the circulation position of the buffer, since the buffer circulates a lot faster than characters can be entered from the keyboard. The system can be backspaced to the beginning of the current word (to permit overwriting for correction) in response to a word backspace key, this causing the column counter to be effectively decremented by one (by being incremented by n- 1 where n is its capacity) in response to equality in the comparison, repeatedly (in response to successive equalities in the comparison) until a space flag is detected in the buffer in the column position preceding that specified by the column counter, so that the system backspaces to the column after the space.

Title: Improvements in or relating to audio-frequency signalling systems
IPC: H04Q1/446
Filed: 1952-07-11
Abstract: 704,650. Voice-frequency signalling. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 11, 1952 [July 13, 1951], No. 17599/52. Class 40 (4) Voice-frequency calling signals are generated at a substation by causing a charged condenser to discharge through an inductance coupled to the exchange line. As shown, on the initiation of a call the line equipment LR causes a finder F to associate a relay set R with the calling line. Feed relay R2 pulls up to the loop offered by the subset transformer TT, and the register-finder V associates a register M, R1 then coming up over arc Vc to reverse the battery polarity over the calling line. The subset talking apparatus is thus effectively disconnected by rectifier D1 and the number sender is connected up over rectifier D2. The lamp O lights in the loop to indicate that keying may commence and condenser C3 is charged. Depression of a key P1-P10 connects C3 in an oscillating circuit with part of the right-hand winding of ST to generate one of ten voicefrequencies which is selectively received by filters T1-T10 at the exchange, the digit being registered in RM. When all the necessary digits have been received, RM controls the setting up of the connection, finally operating R3 to switch through and release R1 which restores the polarity on the calling line to normal.

Title: Photographic film units
IPC: G03C8/42
Filed: 1971-05-27
Abstract: 1356968 Film units EASTMAN KODAK CO 27 May 1971 [4 June 1970(2)] 17636/71 Heading G2X In a self-processing film unit of the type in which a pod of processing fluid is ruptured and its contents spread between a photo-sensitive sheet and a receptor sheet, a trap for excess fluid comprises means at the trailing end of the unit disposed transversely, and such that less fluid is accepted at its centre than at its ends. As shown in Fig. 3, when the pod is ruptured by passing between rollers 20, the liberated fluid, as it is spread between the photo-sensitive sheet 5 and the receptor sheet 7, tends to flow in the form of a curved wave front, with the apex at the centre. Thus the corners 52, 54 may not receive sufficient fluid. A blocking member 60, extending transversely of the film unit 1 but not all the way across, is securely adhered to the sheets 5 and 7. As the fluid reaches the member 60, it is diverted to each edge of the film unit, and passes through the openings 62, 64 at each end of member 60 to the trap area behind it. In the modification of Fig. 7 the blocking member is formed with arcuate corrugations 60'. Thus a minimum of fluid is collected at the central corrugations, while most is directed away to the outer corrugations, which can collect a greater amount of the fluid. Various alternative forms of the blocking member designed to have the same differential effect are illustrated in Figs. (not shown) 12-15.

Title: Electric apparatus for sending out the time
IPC: G04C13/02
Filed: 1921-06-29
Abstract: 186,681. Bulls, M. P. Favre-. June 29, 1921. Electric clocks.-An electric apparatus for sending out the time comprises a controlled electric transmitter consisting of a distributor serving one or more receivers which have rotating fields and in which the rotor follows the intermittent or step-by-step rotations of the field generated by the distributor, a central clock, and a current interrupter which allows the current to flow only during such time as is necessary to operate the rotor of the receiver. Fig. 2 shows diagrammatically the principle of transmission in which the current from the supply E passes through a distributor D which is driven by the central clock and energizes pairs of poles successively by means of the coils B<1>, B<2>, B<3> causing the rotor or armature N. S to rotate step by step in the direction shown. The motion of the rotor is transmitted to the indicator or secondary clock by worm gearing. The current is caused by a current interrupter to be supplied only during such a length of time as is necessary to effect the formation of the rotating field. In the form shown in Fig. 2, this interrupter D' is mounted rigidly on the rotor shaft and consists of a disc having insulating portions H, H<1> cooperating with brushes 1<1>, 2<1>, 3<1> so that the current for any one particular position of the field is broken immediately the rotor has taken up the position relative to the field. In another form the interrupter may be driven by the central clock at a speed differing from that of the distributor D. Fig. 5 shows a form of receiver in which the rotor 15 is of the form shown and is a permanent magnet rotating in an electromagnetic field, the clock-work of the secondary clock being driven by the arbor 16 through worm gearing 21, 22. In another form the stator comprises two soft-iron discs cut away so as to accommodate the coils, which are slipped into position while the discs are together but are gripped when they are spaced apart; the rotor is of soft iron with a flexed coil to obviate slip-ring. In this form alternating current may be employed, since the fields of the rotor and stator are reversed at the same instant and therefore do not affect the direction of the electromagnetic couple. Fig. 13 shows the means whereby the required currents may be obtained from the supply mains C, P with the automatic provision of an alternative supply 5 should the mains C, P fail. The supply to the terminals 50, 51 is derived from the mains C, P or the alternative supply 56 by means of the automatic two-way switch 54, 55, 57, 58. The apparatus is also stated to be of use in setting the secondary clocks fiom the distributor at the central station by disconnecting the distributor from the central clock and driving it in either direction to the required extent and speed.
