IPC: G06F3/06
Filed: 1953-02-11
Abstract: 741,950. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 29, 1954 [Feb. 11, 1953], No. 3814/53. Class 106 (1). An electronic digital computer comprises main digital storage devices, control means by which instruction words control the operation of the main digital storage devices, and supplementary digital stores which are not directly involved in computing operations, and is characterized in that there is provided a supplementary control means, operating when a given group of digits of an instruction word is in a selected permutation, to control the supplementary digital stores by a different group of digits of the same instruction word. In a serial-mode computer a 32-digit instruction word normally orders the transference of data from a particular source to a particular destination, certain groups of digits representing these locations, which are both in the main store, setting up trees ST and DT, Figs. 1, 2, the timing and duration of transfer being controlled by an " Instruction timing control '' C, which can be of the kind described in Specification 719,066. Data from a supplementary magnetic drum store is introduced into a particular section of the main store when a particular destination, denoted by DM, is specified, the " source " digits then being admitted, via gates G5-G9, to staticisors S5-S9, where they, together with digit 10, which is staticised on S10, select either a read or write head of one of 32 tracks on the drum. After a suitable delay, not shown in Fig. 2, a trigger 101 operates to control the timing of the transfer, called a " magnetic transfer " between the selected track of the magnetic store and the main storage device. During a magnetic transfer one line of the source tree ST will, of course, be energized and information will be given access to the highway, but this will not matter since there will be no gate open by which it can leave the highway. Three other embodiments are described for controlling a supplementary store consisting of magnetic drums when the total number of tracks exceeds 32. In the first (Fig. 4, not shown), two consecutive instructions are used to control a magnetic transfer, and in the second and third (Figs. 5, 6, not shown), the " wait" digits are used in addition to the " source " digits to contiol the magnetic store. Specifications 717,114, 719,066 and 732,221 are referred to.

Title: Styrene polymer foam and preparation thereof
IPC: C08J9/14
Filed: 1977-01-31
Abstract: Thermoplastic synthetic resin foam articles are described which, in accordance with machine production, are elongated principally in the longitudinal direction and have a cross sectional dimension of at least 6.35 mm and a cross sectional area of at least 51.6 cm<2>, where the cells have a mean cell size in the range from 0.1 to 1.2 mm. These cells contain at least one low-permeability halogenated blowing agent. The blowing agent remains in the cells during use of the foam articles, for example for insulation purposes, and there is no significant release thereof into the atmosphere. On the one hand, this prevents readily volatile halogenated blowing agents entering the ozone layer around the earth, where they can have a damaging effect, and on the other hand very low thermal conductivity of the foam articles is achieved, significantly lower than that of the corresponding foam articles containing air instead of the low-permeability blowing agents.

Title: Improvements in television systems
IPC: H04N5/12
Filed: 1941-03-24
Abstract: 562,843. Television; valve generating circuits. MAGUIRE, I. L. March 24, 1941, No. 3980. Convention date, March 26, 1940. [Classes 40 (iii) and 40 (v)] In order to avoid the generation and transmission of separate synchronizing pulses, the oscillators at the transmitter and receiver for. producing the line and frame deflecting potentials are controlled by pulses derived from a source of alternating current (such as the mains) at each station. In the receiver shown in Fig. 1, the frame deflecting potentials in circuit 16, 18 are produced by a relaxation oscillator V3, C5, R13, and the line deflecting potentials in circuit 22, 23 are produced by a multi-vibrator V4, V5, the phase of these potentials being controlled by an, alternating current applied from terminals 1, 2 through a phase-adjusting circuit C1, R1, R2 to valves VI, V2, which produce peaked pulses..The valves V1, V2 derive their anode potentials through choke L1 and potentiometer PD, and the valves V4, V5 through choke L2. The grid potential of valve V1 is made so negative that current only passes through the valve when the A.C. potential at terminals 1, 2 is near its maximum, and C2, R10 are so chosen that a sharp peak is given to the negative pulse applied to the grid of V2, the anode circuit of which includes condensers C3, C4 and a resistance R12, so chosen that alternate positive and negative potential peaks are applied to the grid of valve V3. During the positive peaks, relaxation condenser C5 discharges, and grid current charges condensers C3, C4 negatively with reference to the grid, thereby preventing the flow of current in valve V3 while condenser C5 is recharging through resistance R13. The grid of valve V4 of the multi-vibrator V4, V5 is comiected over C6, R4 to the anode circuit of valve V1, so that the multi-vibrator is synchronized in much the same way as the oscillator V3. In a modified circuit, Fig. 2 (not shown), the triode valve V4 of the multi-vibrator is replaced by a pentode, and the relaxation oscillator V3 is connected to the frame deflecting circuit through two additional amplifiers. In further modifications, Figs. 3 and 4 (riot shown), the valves V1, V2 are omitted and the terminals 1, 2, Fig. 1, and phase adjuster are connected to the grid of valve V3 through a condenser-resistance combination similar to C3, R12, C4, Fig. 1, the resistance R2 being shunted in Fig. 3 by a diode and further resistance.

Abstract: 840,787. Pulse delay circuits. STANDARD TELEPHONES & CABLES Ltd. Feb. 7, 1958 [Feb. 9, 1957], No. 4077/58. Class 40 (8)] A ferroresonant circuit for delaying the transmission of electric intelligence comprises an inductance and a capacitance, one of which is saturable, i.e. has a core or a dielectric of ferro-magnetic or ferro-electric material, and a resistance for damping oscillations ; and the circuit is such that the delay of the output signal is equal to the time required to drive the saturable component from a state of saturation with one polarity to a state of saturation with the opposite polarity. Figs. 3 and 4 show suitable circuits incorporating a saturable inductance SR and a saturable capacitance SC respectively : the damping resistances R and G, being such that the signal output voltages do not exceed the signal input voltages, whereby the output signals follow the form of the input. Fig. 9 (not shown), embodies two such circuits in series to obtain a greater delay but having a damping resistor replaced by two resistors in series, one being shunted by a rectifier to compensate for the difference in time available for charging and discharging the capacitor. The inductance may be provided with a D.C. controlled premagnetizing circuit.

Filed: 1926-02-12
Abstract: 247,593. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Aalborg, C.). Feb. 12, 1925, [Convention date]. Automatic circuit-breakers for direct-current traction &c. circuits have a floating lever 1 carrying the bridging contact-member 2 which is pivoted at its lower end 15 to the lower end of a bell-crank lever 18 which moves about a fixed pivot 26 and has the end of its second arm 19 pivotally attached at 32 to the core 31 of a closing electromagnet 4. The contact-member 2 is maintained closed by the attraction of an armature 44 to a. manitaining electromagnet 42 the armature being attached to a U-shaped pivoted lever 51 pivoted at 52, a link 53 connecting this lever to the contact lever 2. A straight conductor 45 passes through the air gap of electromagnet 42 and is connected in parallel with a reactor 46 in the load circuit so that on a sudden current surge the magnetic effect of the current passing through conductor 45 shifts the flex of the electromagnet 42 from the upper to the lower pair of pole faces and the attraction of the armature is then overcome by a spring 6 acting on the contact lever which moves it rapidly to the off-position in which its rear portion 34 is held against a fixed stop 33 which may be provided with a shock-absorbing spring 35. Tore-close, the closing electromagnet 4 is energized, rotating the lever 18 about its pivot 26 against the action of the spring 7. During this movement the pivot pin 15 between levers 1 and 18 moves in a clockwise direction, the lever 1 moving about the fixed stop 33 as a fulcrum so that the link 53 moves to the left bringing the armature 44 into engagement with the poles of electromagnet 42. On de-energizing the electromagnet 4 by opening its control switch 65 the spring 7 returns the lever 18 so that its rear portion nearly engages the adjustable stop 29, the contact lever during this movement pivoting about the point 13 at which it joins the link 53 and so bringing the member 2 in engagement with the fixed contacts, the lower of which may be attached thereto by a flexible lead 41. An arc chute 36 and blow-out magnet 37 are provided and a resistance 66 may be arranged across the circuit-breaker contacts.

Class 103(6) A railway vehicle underframe comprises an integral centre draft sill 1, Figs. 1. 2, and bolster arms 2 of box section. The top and bottom walls of the bolster merge with the top and bottom walls 6, 9 of the draft sill and the bolster side walls 11, 12 merge through curved wall portions 14, 15 with the draft sill side walls 7, 7a tc strengthen the underframe by eliminating angular intersections. Rear draft lugs 18. Fig. 4, on the sill side walls 7 are reinforced by rearwardly extending curved webs 19 which merge into a central longitudinal web 20. Web 20 is connected to a transverse web 21 which merges with sill side walls 7a. The webs 19, 20, 21 transmit impacts from draft lugs 18 to the centre sill rearwardly of the bolster and the web 21 also forms a tie resisting tension on the rear walls 12 of the bolster arms. A horizontal web 23, spaced from webs 19 and intermediate the top and bottom walls of the underframe extends across the sill and connects bolster side walls 11 and curved wall portions 14. The lateral extremities of the web 23 extend along the side walls and are curved about apertures 24 therein. Web 23 acts as a strut to resist compression of the bolster due to buffer forces. A transverse web 22, which joins webs 25 extending transversely of the bolster arms is centrally positioned between the bolster side walls and extends from side bearings (not shown) formed integral with bolster bottom walls in order to provide additional vertical rigidity longitudinally of the bolster. A body centre plate 26 is formed in the sill bottom wall 9 at the mid-point of the junction of the bolster and sill, which plate has a pin hole 27 and webs 20, 22 have elongated openings 29, 30 immediately above the hole for a centre pin. The sill has conventional forward draft lugs 22, draft key slots 33 and striking plate 34. The outer ends of the bolster arms may be formed as at 35 to receive side sill elements and a conventional centre sill may be welded to the rear portion of the sill.

A thermostat inside a building and controlling heat-regulating means therefor is controlled by a thermostat outside the building so that a constant internal temperature is maintained notwithstanding weather changes, the latter thermostat operating to vary the mutual inductance in a transformer or the selfinductance of choking coil in circuit with an auxiliary electrical heating winding on the internal thermostat. As shown a bi-metallic spiral 13 enclosed in a casing 2 external to the building turns an armature 6 carrying secondary coils 7, 8 of a transformer 4 from the position shown to another at right angles to it as external temperature rises, the bi-metallic member having an auxiliary heater 11 supplied from the coil 8 which renders the thermostat subject to weather conditions additional to temperature. The heating current supplied from the coil 7 to an auxiliary heater 9 on a thermal switch 10 is thus progressively increased with external conditions which demand less output from the heating system. The thermostat 10 may be that responsive to the temperature of a heating fluid and controlling mechanically, or electrically as indicated a heat regulator 19 such as a flue damper. The external thermostat may comprise a thermally sensitive alloy which changes its permeability with temperature and is included in the magnetic circuit of a transformer or a bi-metal element may move a member to alter the flaps. The heat losses in the transformer or choking coil may be designed to furnish all the heat required by the external thermostat or these losses may be prevented from affecting the thermostat by placing the latter with its heating winding in a separate casing.
