Patent GB-863635-A (GB)
Title: Improvements relating to data storage arrangements, especially for digital computers
Inventor: FROGGATT ROBERT JUSTIN
Filed: 1956-04-07
Abstract: 863,635. Electric digital-data-storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 28, 1957 [April 7, 1956], No. 10674/56. Class 106 (1). A data-storage arrangement comprises a circulating store with input and output points, a signal path including a normally-closed gate connected to one point, means for opening the gate at predetermined times in the cycle of the store to allow transfer of signals, and means for inter-connecting the points after an opening of the gate to shift signals recorded in the store. In the described embodiment which is intended for use with a digital computer, a constant-speed magnetic drum 1 is adapted to receive data from an unsynchronized source such as a typewriter or teleprinter in the form of binary-coded decimal/alphabetic characters. Each character comprises six binary elements, and six characters from a " word." Sixty-four words can be accommodated in one circumferential track on the drum. As each new word is entered all the previously-entered words are shifted in a clockwise direction to make room for it. A positive signal at terminal 14 signals the beginning of an entry or " store " operation; it prepares a gate 13 to pass an output pulse from a counter 15, 16 which output pulse occurs when the first word recorded on the drum reaches a reading-head 9. This pulse sets a trigger circuit 11 which opens a gate 6 to allow signals from the reading-head 9 to be fed forward to a write-head 4 which is spaced one word-distance from the head 9. Thus, the words already recorded on the drum are rerecorded. with a one-word shift forward in a clockwise direction. The last word is followed by a permanent datum signal 3 which initiates a one-word signal Wo and, via a beginning element 20 resets the trigger 11; this shuts the gate 6 and, at the same time, an end element 21 sets a second trigger circuit 12 which opens a gate 7 to allow a new word, available at a terminal 10, to be fed through to the write head 4. The trigger 12 also serves to open a gate 22 which allows six extra character pulses C3, out-of-phase with the counting pulses CO, to be added into the cycle counter 15, 16 so that the output pulse will occur one word time earlier to account for the shift of the information. At the end of the one-word entry period the termination of the pulse Wo, operating through an end element 23, resets the trigger circuit 12. Read-out from the store can be accomplished in a similar manner, and by suitable spacing of the heads characters may be dealt with singly instead of words. Specifications 707,634, 827,582 and 863,634 are referred to.

Abstract: 950,953. Laminates. B.X. PLASTICS Ltd. June 2, 1960 [March 26, 1959], No. 10680/59. Heading B5N. [Also in Division H5] A heating element, for example for protecting sports fields or for horticultural use, comprises a multi-apertured electrically conductive metallic lamina having means for passing electric current therethrough and disposed between two laminµ of synthetic plastomeric thermoplastic material, which laminae are flexible at or around 0 ‹ C. and are laminated to one another between the apertures in the metallic lamina. Suitable synthetic thermoplastic materials are polyethylene of low density, and nylon. Suitable metallic materials are aluminium, and copper and alloys thereof. The metallic lamina may have a unitary structure or it may be a woven or knitted material, e.g. a gauze. The apertures may be of any shape, e.g. circular, square, hexagonal. The means for connecting the metallic lamina to a source of current may consist of tongues or wires connected to the metallic lamina or tongued extensions of the metallic lamina, positioned at either end of the said lamina. In an alternative construction the metallic lamina and the under-lying layer of thermoplastic protrude from the assembly at either end thereof, and metal bars adapted to be connected to a source of low voltage current may be clamped on each side of the protrusions. The heating element may be strengthened by laminating to one side thereof a sheet of relatively non-stretchable fabric such as a textile scrim, or glass fibre fabric and on top of the fabric a further lamina of thermoplastic material. The heating element may be manufactured by introducing the various layers disposed above one another in the appropriate order into the nip of a heated pair of rollers to effect lamination.

Title: Improved needle drive for a linking machine
Inventor: HILBER WALTHER
IPC: D05B7/00
Filed: 1965-03-15
Abstract: 1,035,746. Linkwork. M. HILBER. March 15, 1965, No. 10762/65. Heading F2K. [Also in Division D1] The needle bar of a linking machine is reciprocated axially and also oscillated about its axis, the extent of oscillation being varied by altering the distance between the needle bar axis and the point of connection between a linkage chain coupling the needle bar to a crank and a rocker arm comprised in said chain. As shown, a rotary shaft 10 is connected by a flexible shaft 11 to a crank 13 coupled to one end of a link 16. The other end of the latter carries a pin 18 journalling one end of a rocker arm 14 pivoted at its other end at 15 to the machine frame. An arm 19, which is slidable on pin 18 and which is connected to link 16 by a screwed spindle 17, is coupled by a universal joint 20 to an arm 21 rigid with the needle bar 22 carrying a needle 5 on a crank arm 23, Fig.2 (not shown). The arrangement is such that rotation of shaft 10 imparts to the needle 5 a stroke h and an angular displacement c. The latter may be adjusted in accordance with the pitch of the points 3 on the rotary point dial by means of the screwed spindle 17.

Title: Control of variables
IPC: G05D7/06
Filed: 1975-05-16
Abstract: 1515301 Automatic control systems TECHSYSTEMS Ltd 16 May 1975 [11 March 1974] 10767/74 Heading G3R [Also in Division D2] Errors between actual and desired values of a variable are corrected by means which adjust the variable for a time period which is determined by a digital circuit and depends on the error signal, the time period being less than that required to correct the error. The object is to gradually approach the set value without overshoot. Fig. 5 illustrates the invention applied to control fluid-flow by means of a valve; when the measured value (top curve) is a long way from the set point the valve is adjusted by a large amount (70%) for a time Tl. After a sampling time delay for the effect to work through to the measuring point a further correction, proportional to the new, smaller, error, is applied for time T2, and so on. In this instance adjustment takes place at a constant speed for a variable time, but alternatively the adjustment rate also might be varied. A "backlash compensation" may be applied, i.e. the initial adjustment is increased when the sign of the error changes. The final steps also may be made larger than proportional, to overcome mechanical stiction at small errors. In a digital embodiment Fig. 2A (not shown) the error is represented as a number stored in a counter which is periodically counted down to zero by clockpulses from an oscillator, the control signal being supplied for the duration of this count down. The departure from proportionality referred to above is achieved if required by varying the frequency of the clockpulses in response to the error. In an analogue alternative Fig. 6 (not shown) the valve motor is operated for a time determined by a uni-junction transistor controlled by an RC circuit. The resistance is varied by relay operated switches in response to the error signal in digital (binary) form and a suitable capacitance selected by manual switching to match the parameters of the process. In Fig. 7 the invention is applied to paper making. A desired "bone dry weight" of product is set at 114 and periodically compared at 112 with the measured value of this quantity from 102. The result is switched at 122 to adjust the set point 110 for a system which controls the flow of fibre/liquid feedstock. For this purpose, switches 106 and 122 are periodically changed over so that a valve is adjusted by controller 116 in response to the difference between measured value 100 and the adjusted set point 110. If the error exceeds a prescribed value a fault is assumed, the valve is held at its instant position by "freeze" 126 and a warning is given.

Title: Improvements in optical news projecting machines
IPC: G03B21/134
Filed: 1928-04-13
Abstract: 313,257. Proctor, B. A. April 13, 1928. Feeding webs. - Relates to devices for optically projecting information printed on a web of tape, and consists in the provision of means for controlling the tension of the tape' so that jars or jumps transmitted to the tape by the starting or stopping of the feed will be isolated from the part of the tape in projecting position. The tape T is drawn from a reel 21 and passes to printing- mechanism 22 where news items, such as stock prices, are printed, and thence passes to a guide 17 in front of an optical-projection apparatus. The upper part of the casing 12 of the projection apparatus is cut away to form a guide 25 for the tape, and mounted above the guide 25 is a looped sheet-metal guide 23. Between the guides 23, 25 is a pivotally-mounted rod or lever L adapted normally to press the tape into engagement with the guide 25. After leaving the projectionapparatus, the tape passes over rollers 27, 32 to a constantly-driven roller 35 against which it is pressed by a weighted roller 58. The tape is finally wound on a spring-driven rewinder 42 which is controlled by a lever 53, one end of which rests on the tape, and the other end engages a fly on the shaft of the rewinder. In use, the tape is fed forward by the printing- mechanism, and when this stops, the roller 35 tends still to draw the tape forward. The increased tension on the tape raises the lever L and causes it to press the tape against the guide 23. The continuously-rotating roller 35 will then slip relatively to the tape, but will maintain taut the part in projecting position. When the printing-mechanism restarts, the lever L will be allowed to fall on to the guide 25 and a loop will be formed thereby in the tape. The slack in the tape will not continue beyond the guide and will therefore serve to absorb any jumps transmitted by the printing-mechanism. The remainder 42 continues to operate until the tension of the tape moves the end of the lever into position to engage the fly.

Abstract: 1,182,811. Automatic circuit-breakers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 8 March, 1967 [23 March, 1966; 6 Dec., 1966(2); 23 Dec., 1966], No. 10997/67. Heading H1N. In a thermal timer for use in an electric toaster, a bimetallic thermal element 2, Fig. 3D, is substantially cylindrical and contains a concentric auxiliary heater 3 which is heated to approximately 750 C. so that the bimetal is heated by radiant and convection heat. The bimetal is fixed at one end 2a and carries an operating lever 36 at its free end. A plate 34a serves to retain and conduct convection heat to the bimetal 2. The toasting time is controlled by the heating and cooling movement of the bimetal 2 through lever arm 36 which has a spring arm 37 (Fig. 2) and screw 40 respectively engageable with one of a pair of oppositely rotatable stop lever arms 21, 22 on a common spindle 28 and which control the position of a yieldingly urged abutment member 19 coupled to a spring arm contact 55, Fig. 10A. At the start of a toasting cycle the abutment member 19 engages lever 21 whereby spring arm contacts 55, 57, 59, Fig. 10A, are held out of mutual engagement so that the auxiliary heater 3, Fig. 9, in series with the main toasting heater 1 is in circuit. As the control arm 36 moves to the left (Fig. 2) with increasing temperature of the bimetal 2, screw 40 gradually pushes lever arm 21 clear of the abutment 19 while spring 37 pushes lever arm 22 to a position opposite the abutment 19 thereby limiting its movement to an intermediate position (Fig. 10A) at which spring arm contact 55 engages spring arm contact 57 (switch 5, Fig. 9) to short-circuit the auxiliary heater 3. As the bimetal 2 cools, arm 36 moves back (to the right) disengaging spring arm 37 from lever arm 22 which gradually rotates (clockwise) under action of return spring 23 to fully release the abutment 19. This permits contact arms 57, 59 to engage (switch 6, Fig. 9) and actuate the release solenoid 8 for the bread support of the toaster. Lifting of the bread support results in disconnection of the main circuit switch 4, Fig. 9, and lifts an arm, 17 coupled to the abutment 19 whereby it is withdrawn and the contacts arms 55, 57, 59 restored to the initial open circuit position. Toasting time adjustment is obtained by adjustment of the position of the contact assembly by screw spindle 30 whereby the abutment 19 is moved transversely towards or away from the lever 36. Individual adjustment of the heating and cooling time is obtained by screws 39, 40 on the lever 36 to vary the times of abutment of the screw 40 or spring arm 37 with the levers 21, 22.
