Title: Improvements in and relating to telautography
IPC: H04N1/00
Filed: 1921-04-13
Abstract: 182,928. Bartholomew, H. G. April 13, 1921. Copying telegraphs.-A representation of the matter to be transmitted, such as a half-tone or other etched plate or an impression in wax such as is used in phonograph records, is used to control production of sound signals corresponding with the elements to be sent, and the sound signals are transmitted by line or wireless telephony. At the receiving end, the signals are used to control the reproduction. The representation may produce the sound signals by direct action, for example, by means of a stylus connected with a diaphragm, and cause to traverse the representation. Preferably, however, the representation controls the circuit of a sound-producing device such as a buzzer. The plate &c. 6, bent to or made of cylindrical form, is mounted on a mandrel the spindle 2 of which has a leading-screw 3 to give axial movement during rotation, and a contact stylus 5 co-operates with the plate to make and break the circuit of a buzzer 8. The sounds produced are transmitted by telephone 9 to a receiver 10, which causes a phonograph-like recording device 11 to produce a record corresponding with the impression on the plate 6. The receiver 10 may be replaced by an electromagnet with a sluggishly-acting armature which carries the recording-stylus. The record may be used to control a stylus-operated make-and-break wire, which in turn controls the movement of a lightsensitive surface so as to vary the exposure of successive areas or picture elements to give a photographic reproduction. Control signals may be sent at intervals by means of a commutator associated with the transmitter mandrel. As shown, a cam 18 driven through gear 19, 20 from the spindle 2 closes contacts 21 at intervals to operate a recording device for control signals, or to control directly the speed of the receiving apparatus. Specification 197,402 is referred to.

Title: Control systems
IPC: B64C13/00
Filed: 1972-03-08
Abstract: 1382145 Fluid-pressure servomotor systems AUTOMOTIVE PRODUCTS Ltd 7 March 1973 [8 March 1972] 10808/72 Heading G3P A control system has a piston and cylinder device 70, Figs.1 and 5, associated with a by-pass valve 28B and an electrically operated servovalve 59B connected to a source of pressure fluid through a solenoid valve 27B which also supplies pressure fluid to the by-pass valve to hold it closed against a bias. In the preferred embodiment, a second piston and cylinder device is connected to the first by links 88, 90 and four servo and solenoid valves are connected to form a pair of similar sub-systems A and B each of which is supplied through a further solenoid valve 16A and 16B, a filter 12A, 12B, a strainer 11A, 11B and a non-return valve 10A, 10B. The supply is also connected through filters, by-pass valves 115A, 115B, flow regulators and mechanically operated servovalves 96A, 96B to a tandom piston and cylinder device 101 for operating a control surface on an aircraft. The valves 96A, 96B are coupled by a link 95, Fig.6, pivotally mounted on a pin 100, to the link 88, the output from the device 101 being fed back to the pivot through a linkage 185, 174 to the pin, and through a link 126 to four feedback potentiometers connected with input amplifiers 69A, 69B to the system. If the fluid-pressure supply to both hydraulic subsystems fails, causing a fall in pressure in lines 30A, 30B, pressure in supply lines 159A, 159B, displaces a device 142 to release a catch 165 and to lock a pivot pin 97 on the link 95 so that the valves 96A, 96B may be operated manually from a linkage 183, 178 and 168, feedback being applied to the link 178 from the linkage 185. If one of the by-pass valves 27A...28B is displaced by its bias due to a failure or leakage in the fluid supply, a switch 67A, 67B is operated by a recess (56A), Fig.4 (not shown) in the valve stem to operate the corresponding solenoid valve 27A, 27B and cut-off further fluid supply. These switches also switch on a warning lamp in a circuit including switches operated by relative movement between separate pistons in each of the devices 70, 71 or by pivotal movement of links 88, 90 a further switch 191, Fig. 10, interrupts the supply to all of the solenoid valves if pressure fails in both of the sub-systems allowing pistons 221A, 221B to be retracted by spring biasing means. The circuit may be arranged to include more than one warning lamp.

Title: Improvements in and applicable to knitting machines and the production of fabrics thereon
IPC: D04B15/54
Filed: 1923-04-23
Abstract: 223,260. Harriman, C. G., and Hulse, W. W. April 23, 1923. Circular, parallel, straight-bar, and warp machines.-Electromagnetic means are provided for moving a thread guide or guides between individual needles to lap one or more needles on the front and one or more needles on the back, the guide or guides being instead of or additional to the usual thread guides. In the circular latch needle machine shown in Fig. 1 the pivoted thread guide 3 is passed between the needles 2, sliding in a fixed cylinder, by its connection at 12 to a horizontal armature 4 the ends of which are each accommodated in a solenoid 5 electrically connected to a pair of distributing rings 6. The standards 13 carrying the solenoids 5 and rings 6 are secured to the rotating cam-box. The swinging movement of the guide 3 is controlled by the spacing of conductive and non-conductive projections on the rings 6 which engage brushes 7 connected to an electrical supply 8. The travels of the armature 4 may be adjusted by a screw inserted in the outside end plates of the solenoids and one armature may be used, by suitably pivoting the guides, to move simultaneously two thread guides in opposite directions. Fig. 4 shows a warp machine with two rows of warp guides 20 and provided with a pair of solenoids 5 located at each end and secured to carriers 21 adapted to slide in a plate 23 which is adapted to be rocked on a pivot 24 by the usual rocking mechanism, which effects an oscillation, in one direction or the other, of the whole of the two rows of guides collectively, the movement of either row, independent of the other row, across the needles being effected by energizing the respective solenoids. This may be done by a suitably perforated pattern band passing over a roller of conductive material and a spring- pressed brush adapted to make contact with the drum at each perforation, thus closing the electrical circuit through the corresponding solenoid. In the warp machine shown in Figs. 7 and 8 the thread guides 20 and guide bars 34 are carried from a rocking shaft 35 by rods 36 sliding on arms 37 on the shaft and each guide is adapted to slide on a rod 40, secured by brackets 39 to the shaft 35. Independent oscillation of the guide, bars is effected by the energizing of solenoids 5 located transversely side by side at each end of the machine and to the armatures 4 of which are connected links 46 pivoting upon the rods 40 and connected to the guide bars 34. In the straight-bar machine shown in Fig. 9 the pivoted thread guide 50 is swung between the needles 56 by the solenoids 5 carried bv a bracket travelling the length of machine, brushes 51 thereon making contact with distributing bars 52 having contact studs 53. Modifications are described in which the solenoids are disposed vertically as shown in Fig. 11. Other arrangements of solenoids and methods of energizing them at the desired intervals, e.g. by alternating current, are described.

IPC: F04B43/02
Filed: 1956-04-12
Abstract: 825,755. Reciprocating pumps. GASKELL & CHAMBERS Ltd. April 3, 1957 [April 12, 1956], No. 11123/56. Class 102(1) A pump comprises a cylinder 3 housing two pistons 4 and 5 separated by a column of liquid, the piston 5 being actuated by an electric motor through a worm gear to pressurise the liquid column which provides the power stroke of the piston 4. The piston 4 may itself form the pump piston or may be connected by a rod 6 to a pumping diaphragm 7, the housing 10 containing suitable inlet and outlet valves. The piston 5 is provided with a stem 14 having a head 15 which is permitted limited movement within the piston 4 such that the piston 4 can be moved inwardly by the head 15 on the suction stroke whilst the piston 5 can move outwardly on the power stroke without imparting movement to the piston 4 by means of the head 15 of the stem. The liquid between the two pistons extends into an upwardly directed port 16 which is closed by a piston or diaphragm 17 loaded on the outer side by a predetermined yieldable force which may be applied by a weight 18 on the end of a pivoted arm 19 or a spring. In operation the piston 5 operates through the liquid column to produce the power stroke to the pumping element until force due to the back pressure of the pump exceeds the yieldable force acting on the piston or diaphragm 17, continued reciprocations of the piston 3 will cause the force to yield and permit the piston or diaphragm 17 to reciprocate with the piston 5 whilst no movement is imparted to the piston 4.
Patent GB-595094-A (GB)
Title: Improvements in or relating to cathode ray tube display systems
IPC: G01S13/524
Filed: 1945-05-02
Abstract: 595,094. Radiolocation. OATLEY, C. W., ELLIOTT, W. S., and PURSEY, H. May 2, 1945, No. 11192. [Class 40 (v)] Recurrent pulse signals of a periodically varying amplitude, which are displayed on a cathode-ray tube display system, in which successive traces are displaced from each other, e.g. a P.P.I. in a pulse radar system, are distinguished from signals of substantially constant amplitude by periodically reversing the polarity of the signals applied to the cathoderay tube at such a frequency that the indications produced by the signals of varying amplitude are striated, in consequence of the low-frequency beat between the amplitude variation and switching frequencies. In a pulse radar system, the echo signals are mixed with a signal of the transmitted radio-frequency, so that echo signals received from moving objects become amplitude modulated due to the Doppler effect. Figs. 1a, 1b show, when one particular type of demodulator is used, the video signals obtained from echoes from stationary and moving objects respectively, and Fig. 1c shows the video signal, corresponding to a moving object, obtained with another type of demodulator. With the latter system, the signal 1c is periodically reversed in polarity at a rate approximating to the modulation frequencies of the desired signals by the switching waveform shown in Fig. 1d, which results in the signal shown in Fig. 1e. The irregular waveform 1e which contains a component shown by the dotted line z is then applied to modulate the beam of a P.P.I. tube, the resulting signal indication appearing as a series of bright and dark striations. This indication will be produced only for signals having a modulation frequency approximating to that of the switching frequency ; a constant amplitude signal will produce an indication of constant intensity unless the switching frequency is low or the aerial scanning rate high. Fig. 2 shows the receiving circuits wherein a receiver 1 of standard form is fed with signals from an oscillator 2 which is locked in phase with the transmitted radio-frequency by signals sent over line 3. The receiver output is applied to the video amplifiers 4, 5, the outputs of which are substantially equal, but of opposite polarity. An electronic switch 6 selects the outputs from these amplifiers alternately and applies them to the cathode-ray indicator 7.
