Title: Improvements relating to electrically operated register assemblies
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04M1/272
Filed: 1952-06-27
Abstract: 730,391. Automatic exchange systems. SIEMENS BROS., & CO., Ltd. June 19, 1953 [June 27, 1952], No. 16300/52. Class 40 (4). In a register sender in which each digit is registered in the first of a series of registers, a full register preceding an empty register automatically transfers the stored digit which is sent from the last register. Thus providing the digits are sent as fast as they are registered, the register sender can handle a called number having more digits than there are registers. The operator registers a digit by connecting battery over back contacts of relays A, DS to one or more of leads W . . . Z, say Z, whereupon AZ operates, recording the digit in register 1 and connecting its holding winding in series with the associated control relay A. Relay A disconnects the low resistance battery from the key set, allows DS to operate and completes a circuit over a front contact of the energized recording relay AZ for the corresponding relay BZ in register 2. Relay BZ shunts down AZ, whereupon A falls back, connects up the control relay B of register 2 and, providing the restoration of the key-set has released DS, reconnects low resistance battery to the key-set so that the second digit can be recorded in register 1. A lamp shows whether or not register 1 is occupied. The first digit is passed from register to register until it is recorded by FZ in the last register 6. When register 5 is cleared its control relay E releases and control relay F operates. Relay S then pulls up energizing a selfimpulsing relay P which actuates PA and PX to repeat the impulses to the outgoing loop LO and a counting chain CA . . . CD respectively. When the operated counting relays CA . . . CD correspond to the operated recording relays FW . . . FZ, all short-circuits around relay SZ are removed and relay SZ closes the outgoing loop and clears the counting chain and register 6. Relay S releases, followed by F so that the digit recorded in register 5 is transferred. Relay S by releasing energizes the impulsing relay P which through PX steps the counting chain CA ... CD until the holding circuit for SZ which consists of strappings connected to back contacts of the counting relays CA ... CD and determining the inter-digital pause is broken. SZ falls back, disconnects the impulsing and counting relays and allows S to operate if another digit has been recorded in register 6. The earth for the recording relays may be connected by a relay operated by the dialling key. This relay is released, providing SZ is operated, e.g. by the disconnection of the card circuit, and returns the register sender to normal. Specifications 471,987 and 573,885 are referred to.

Title: Method and apparatus for analysing a signal
IPC: G06G7/75
Filed: 1963-04-25
Abstract: 1,002,476. Selective signalling. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 25, 1963 [April 27, 1962], No. 16378/63. Heading G4H. [Also in Division G1] To analyse a signal showing a number of peaks the signal 1 is converted at 4 into electrical impulses the frequency of which is proportional to the momentary magnitude of the signal; the entire series of pulses, corresponding to the whole signal to be analysed is passed to a memory 7 and recorded therein and simultaneously or subsequently these impulses are released to a translator 8 which in consequence adjusts a resistance 9 to be proportional to the number of impulses received, the current through the resistance from the controllable direct current source 10 being controlled in such a way that the voltage across the resistance, when the resistance has reached its final value, assumes a certain value. The direct current source is maintained at this controlled setting. The impulses recorded in the memory are then supplied by groups, each group corresponding to a peak of the signal, to the translator 8 by reading out the memory 7, the resistance 9 being reduced to its zero value before each group is read-in; and the voltages which occur across the resistance 9 are measured at least whenever this resistance has reached the final value corresponding to a certain peak. This method analysis is particularly of use in dealing with the electrical outputs of gas chromatographs, wherein a measure of the area of a given output peak, taken as a proportion of the whole output, yields the proportion of a corresponding component in the gas mixture. Groups of pulses corresponding to different outputs are stored in the memory 7 and separately compared with a voltage representing the overall output by using the variable resistor 9 to which is coupled a recorder 12. The circuitry between the input signal 1 and the converter 4 includes an attenuator 2 which can be switched in or out of circuit by means of the relay 17 according as to the magnitude of the input signal. If it is out of circuit because of a small input signal, then a frequency divider 5 is brought into circuit after the converter so that all signals are either attenuated before or frequency divided after passing the converter by the same circuit. A correction circuit 3, which may be a variable attenuator or amplifier is also included and is adjusted to compensate for the varying sensitivity of the apparatus to different components obtained in the analysis. The arrangement for adjusting the D.C. source 10 in accordance with the maximum setting of the resistance 9 consists of a differential amplifier 15 which responds to the difference between the potential across the resistance 9 and that of a fixed source 13 to drive a servomotor 16 which adjusts the D.C. source 10 until no difference is obtained.

Title: A self-acting, electro-mechanical programming apparatus
IPC: G05B19/14
Filed: 1956-05-28
Abstract: 803,623. Switching systems. VIDAL, A. P. L. May 28, 1956 [June 8, 1955], No. 16421/56. Class 38 (4). [Also in Groups VI, XXXVII and XXXVIII] An electromechanical programming apparatus includes a perforated card device 15 which, in dependence on the position of the perforations in each column of the card 16, which co-operate with a plurality of contacts 19 under the card and associated individual " brush' contacts 21 positioned above the card, supplies current via a plurality of conductors 24 to banks of contacts 5 . . . 10, the latter closing in predetermined order and for predetermined intervals determined by the angular position and the profiles of a rotating cam assembly 2, 3, 4 to prepare via electromagnetically-operated contacts 23 the circuit of a device A which circuit is completed, if the perforated programme requires it, via conductors 25 and the appropriate one of contacts 19. When the cam 2 of the assembly has " passed " its associated contact (i.e. contact 11) the electromagnet 22, which operates contacts 23, is deenergized thus opening the circuit of device A and allowing the pawl 18 to release the carriage 14 which is then moved towards the left-hand side a distance equal to the width of one column under the action of a spring mechanism. The interval which elapses before the next sequence commences is determined by the particular one of the bank of contacts 5 ... 10 to which the conductors 24 associated with the particular " brush " contacts 21 which cooperate with the perforations in the next column are connected, the maximum interval (between bank 5 and bank 10) being six seconds, which is the time for one revolution of the cam assembly (driven at constant speed by motor 1) and the minimum interval one second (between any two adjacent banks). In the present arrangement each column of the card 16 may have a maximum of twelve perforations the first six being effective over individual contacts 19 and 21 and conductors 24 to complete circuits to the contact banks and the remaining perforations effective over the other individual contacts 19 and 21 and conductors 25 to complete the circuit of individual devices A (maximum of six) already prepared by the first set of perforations. By employing a second set of contacts 19 and 21 the number of devices, such as A, controlled by the apparatus may be doubled. An application of the invention in experimental psychology in which the reaction of a subject as indicated by the subject closing or not closing (as required by the programme perforated on the card) an electric switch in response to an external stimulus (e.g. sound or light &c. signal produced by device A) is determined and the time of such reaction measured is described in connection with Fig. 3 (not shown).

Title: Improvements in and relating to servo systems
IPC: G05D3/14
Filed: 1944-08-30
Abstract: 616,248. Follow-up systems. SPERRY GYROSCOPE CO., Inc. Aug. 30, 1944, No. 16527. Convention date, Aug. 30, 1943. [Class 40 (i)] In a system in which an electric servomotor is controlled in accordance with the sense and magnitude of an error signal, the motor is a commutator motor in which the error signal controls the field excitation and variations of armature current resulting from the E.M.F. due to rotation of the armature are limited so that the torque remains proportional to the signal. As shown, Fig. 2, the error signal from coarse and fine selsyns which, owing to the presence of rectifier systems 37, 38 and 31, 32, are effective one at a time, is mixed with an anti-hunting signal derived from a tachometer generator 14 and differentiating circuit 54, 55 in a circuit involving a pair of twin triodes 42, 43 with an alternating plate supply to render the circuit phasesensitive. The resulting signal is amplified and applied to field windings 59, 60 of the servomotor. Variations of armature current are limited by a series resistor, capacitor or, as shown, inductor 62. In a modification, Fig. 3, the anti-hunting signal modulates, with the aid of a rectifier bridge 80 ... 82, a reference voltage 12 which is applied in series with the error voltage to a triode amplifier 66 feeding a push-pull amplifier 72, 73 similar to that in the system shown in Fig. 2. In another arrangement, Fig. 4 (not shown), the final amplifier is a single triode and the effect of the steady anode current is neutralized by an additional field winding carrying a direct current.

Title: Spinning of Conjugate Filaments
IPC: D01D5/24
Filed: 1968-04-05
Abstract: 1,150,399. Spinneret for conjugate filaments. INVENTA A.G. FUR FORSCHUNG UND PATENTVERWERTUNG ZURICH. 5 April, 1968 [6 April, 1967], No. 16572/68. Heading B5B. In a process for the production of conjugate filaments of two or more polymers from streams of melts or solutions of the polymers having different viscosities, in which the streams are spun together in the proportions necessary to form the desired filament through a spinneret plate having a planar outlet side, the spinneret holes are perpendicular to the plane of the plate and the cross-section of each hole is so shaped as to impose increased frictional resistance on the stream of lower viscosity to offset the tendency of the conjugate filament to deviate from the axis of the spinneret hole, so that the streams unite within the holes and emerge together from them and flow thereafter at least substantially perpendicularly to the plane of the plate. A theoretical discussion is given. Figs. 2, 6 and 8 show cross-sections of spinneret holes suitable for the extrusion of conjugate filaments of round cross-section, the stream of lower viscosity flowing in either case through the zone 1, Figs. 3 and 4 show cross-sections of spinneret holes suitable for filaments of Y-shaped crosssection, Fig. 5 shows a hole suitable for filaments of flat strip-like cross-section, Fig. 9 one suitable for a lobed filament, and Fig. 7 shows a form of spinneret hole for two-component hollow filaments. The spinneret hole has a core 3 with a bore 4 through which the gas producing the cavity issues during spinning. It is also possible for a third polymer component to issue through the bore 4, so that a threecomponent core-and-sheath filament is formed, said filament having a sheath composed of two different polymers.

Title: Apparatus for and method of die casting under vacuum
IPC: B22D17/14
Filed: 1958-05-27
Abstract: 868,732. Injection-moulding machines. MORGENSTERN, D. M. May 27, 1958 [May 31, 1957], No. 16840/58. Class 87(2). [Also in Group XXII] A method of injection moulding plastic material consists in enclosing the dies 20, 22 within an evacuated chamber 85 so that the material is degassified before being cast. The die 22 is moved through toggle links 7 by a fluid-pressure device. Ejector pins 26 are operated by a rod 27 which abuts a stop supported on the tie-rods. A rod moving with the die 22 carries dogs to actuate controlling switches. An injection pipe 55 extends through the fixed die 20 and communicates with a heated crucible 65 by way of a metering orifice 63. The material is injected by a fluid-pressureoperated ram 70. The die 22 carries a dam 80 which enters the pipe 55 and is formed with a channel 82 communicating with the die cavity. The chamber 85 comprises an adjustable hood 87 co-operating with a telescoping hood 86. The interior of the hood 86 communicates by way of pipe 135 with a vacuum tank. The pipe 135 contains a closure valve operated in conjunction with a relief valve. In operation, a push-button is depressed causing the die 22 to be advanced to the position shown, where it dwells. During the dwell, the valve in the pipe 135 is opened and the space around the dies is evacuated together with interior of the pipe 55, via the channel 82. Plastic material then commences to enter the pipe 55 via the the metering orifice 63 and builds up behind the dam 80 whilst being de-gassed. After the dwell, gauged by an electrical timer, the dies are closed by the toggles. The ram 70 then injects the material into the dies, a slug of material being left between the ram and the dam, and atmospheric air is omitted to the hood. The slug is pushed forwardly by the ram 70, as the dies are opened after a further dwell period, and is carried with the moulding. The moulding is subsequently ejected and the parts returned to their initial positions. The degree of vacuum in the hood should be not less than 19 ins. Hg and may be controlled by a slide valve 280. Reference has been directed by the Comptroller to Specifications 780,126 and 860,030.

Title: Improvements in or relating to apparatus for bringing solids and gas into contact
IPC: B01F23/30
Filed: 1952-07-04
Abstract: In apparatus for bringing powdered solids and gases into contact, the level of the solids in contacting vessel 201 is regulated by feeding the solids through pipe 203 into an auxiliary vessel 208 open only at the top and surrounded by a skirt 209, and introducing an auxiliary gas at 211 from pipe 210 provided with a pressure regulator 213.  Gas is introduced into the main vessel at 204 and leaves at 205; solids are removed at 206.  The solids are fluidized <PICT:0742928/III/1> in vessel 208 and flow out the top of this vessel down within the skirt 209 into the main bed, which also may be fluidized.  As the level rises in the vessel 201, the flow of gas to the auxiliary vessel is reduced so that less solids enter through pipe 203.  The auxiliary gas may be part of the gas leaving the main vessel.  The container 202 from which the solid is fed may be a hopper, a cyclone, or a further contacting vessel through which the solid is circulated. Reference is made to the use of the apparatus in the catalytic conversion of hydrocarbons.
