Title: Improvements in or relating to co-ordinate switching arrangements
IPC: H04Q3/00
Filed: 1960-10-13
Abstract: 905,452. Automatic exchange systems. SIEMENS & HALSKE A.G. Oct. 13, 1960 [Oct. 14, 1959], No. 35099/60. Class 40 (4). Each cross-point of a co-ordinate switching array includes a hold winding in series with an associated set of contacts between a row and column wire. The arrangement is more particularly applied to an exchange such as shown in Fig. 2 where three stages of co-ordinate switches A, B and C connect single wire paths between subscribers, each stage operating a contact such as Ka, Kb or Kc which is held by an associated hold winding Ha, Hb, or Hc connected in series with the path and a battery S. The hold windings may be shunted by capacitors or be provided with short-circuit windings to reduce their impedance to -speech. In Fig. 2 the hold windings are also employed as select windings to operate as well as hold their associated contacts as determined by markings extended from a marker M to selected windings along the path. As shown in Fig. 3, however, separate select windings are used for each co-ordinate the contacts being of the sealed tube magnetic type embraced by their windings and having a flux return path R from which the contacts are insulated. The flux return path forms a base in common to a row of contacts and similar rows are stacked one above the other to form the co-ordinate array. Each contact has a centrally positioned hold winding H on one side of which is a co-ordinate winding Y common to the row and on the other side of which is the other co-ordinate winding X individual to each contact and connected in multiple from stack to stack. Once a contact has been operated by coincident drive from an X and a Y winding, and it has been connected in a speech path, the hold windings are energized and the select windings may be released. Short-circuit windings on the hold coils may be provided by coating a metal on the ends of the coils or by attaching conductive rings. Specification 797,913 is referred to.

Title: Improvements in or relating to image-forming systems
IPC: G02B21/36
Filed: 1958-11-03
Abstract: 945,342. Optical display systems. R. L. GREGORY, and P. E. K. DONALDSON. Feb. 2, 1960 [Nov. 3, 1958; June 17, 1959], Nos. 35255/58 and 20863/59. Heading G2J. An image forming and display optical system comprises means for effecting relative movement between a surface on to which the system is focused and the space occupied by the object so that the object space is scanned or swept out by the surface and means to move an image surface in a similar way to display in an image space a three-dimensional image of an object. In the microscope shown, light from a lamp 32a (not shown) is directed on to a slide 31 mounted on a stage 54 and an image of the slide is formed by a lens system 35a on a screen 34 mounted on a prong of a steel fork 58. The slide 31 and screen 34 are made to vibrate in phase by vibrator units 55 and polarised solenoid 59 which are controlled by the following circuit shown in Fig. 5. The solenoid 59 is fed from a 20 watt electronic amplifier 61 which receives a sine wave signal from 50 cycles/sec A.C. mains 62 by way of a phase shifting network 63. The vibrator units 55 are similarly energized by a 10 watt amplifier 64. In order to control the intensity of illumination of each object plane, e.g. to make it equal or to have a particular plane brighter than the others, the lamp 32a is energized from the mains 62 through a choke (not shown) to modulate the intensity at 100 cycles/sec, or through a half wave rectifier. By using the system shown in Fig. 2 in which light from a slide 47 is reflected by mirrors 42-44 on to a screen 48 the slide and screen may be mounted on the same vibrating stage. Instead of having a vibrating stage, a rotating disc formed with plates at successively different distances from the position in which it is to be viewed or a transparent helical disc may be used or the image may be formed on the edge of a rotating eccentrically mounted wheel. The vibrating object can be replaced by a stationary object and a series of objective lenses having different image planes or a helical disc as described above. The intensity of the lamp could be modulated by a revolving apertured disc or by a small vane carried by a vibrating reed.

Title: Improvements in apparatus for aerating liquids
IPC: B67D1/04
Filed: 1929-11-22
Abstract: 341,203. Aerating liquids. SUGDEN, G. F., Sunny Bank, Marple Bridge, Derby. Nov. 22, 1929, No. 35740. [Class 14 (i).] A cylindrical vessel 4 is secured between endplates 2, 3 by tension rods 5. A rotary multi-way valve 22 controls the movement of the liquid and the venting of the vessel, while a separate valve 19 controls the admission of gas. Normally the handles 30, 31 of the valves are vertical. If the handle 30 is turned water enters by a pipe 32 and air escapes by the pipe 37 and through passages 29 in the valve 22 to the outlet 38. When the desired amount of water has entered the handle 30 is raised and the handle 31 depressed. Gas then passes along pipes 17, 12 to a distributer 14, the pressure being registered by a gauge 10. When the liquid is sufficiently aerated the lever 31 is raised and the lever 30 turned until a valve port is opened to discharge the liquid through a nozzle 36 while excess of gas is vented through the pipes 37, 38. A spring-controlled plunger in the nozzle, which is constructed as described in Specification 212,621, [Class 135, Valves &c.], retards the flow until the pressure has fallen suitably.

Filed: 1930-11-29
Abstract: 369,903. Electromagnetic switches. PAYNE, M., 50, Hook Road, Surbiton, Surrey. Nov. 29, 1930, No. 36009. [Class 38 (v).] In electromagneticallyoperated switches in which a spring or gravity-controlled contactcarrying armature and the co-operating fixed contact are enclosed within a sealed vessel containing oil or an inert gas, the external operating electromagnet has a hollow cylindrical iron core which surrounds the tubular portion of the vessel in which the iron plunger armature is located and is formed with annular polepieces so that when the armature is attracted to bring the contacts into engagement, the magnetic circuit of the external magnetic shell is completed by the internal iron plunger. As shown in Fig. 1, the glass casing c is surrounded by an electromagnet h and contains a magnetic plunger e suspended by a spring f from an upper terminal k which passes through a rubber lining g tightly closing the upper end of the casing, the core e having an extension i carrying a resilient movable contact a. The fixed contact b attached to a terminal n is similarly secured to a rubber lining j at the lower end of the casing. The casing is filled with oil or with an inert gas and on energization of the electromagnet the core e is drawn down to bring the contacts into engagement, the upper portion d of the casing being tubular to guide the core in its movements. In a modification, Fig. 3 (not shown), the casing may be of cylindrical formation. The operating electromagnet h is surrounded by a cylindrical magnetic shell h<1> formed with annular polepieces so that the armature e when attracted completes the magnetic circuit between these polepieces. In a further modification, Fig. 2, the movable core e is lifted against gravity on energization of the electromagnet current being led to the movable contact a through a flexible connection l attached to a lateral terminal m.

Abstract: 943,542. Television. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 20, 1960 [Oct. 23, 1959], No. 36010/60. Heading H4F. An arrangement for reducing the effect of " noise " in television picture signal reproduction utilizes the facts that the disturbing influence of " noise " decreases both as the amount of detail in the picture increases and as the video frequency increases. As shown, the video signal output from the detector 5 of a television receiver is supplied to a band-pass filter 8 which passes the H.F. components (e.g. 1 to 5 mc/s.) to a variable transmission device 9 (e.g. a variable-Á valve) controlled by a voltage developed in a device 15 (e.g. a squarelaw rectifier) representative of the energy content of the H.F. components (i.e. image detail) such that as the image detail increases the output of device 9 decreases and vice versa. The latter output is then combined, subtractively, with the entire video signal from amplifier 7 in a circuit 14 which supplies, to a video amplifier 12 and picture tube 13, a video signal, the amplitude of the H.F. components of which varies directly as the amount of image detail in the signal.

Title: Improvements in or relating to the fulling and felting of textile goods
IPC: D06C17/02
Filed: 1954-12-15
Abstract: 770,349. Finishing fabrics. GOBEL, K. Dec. 15, 1954, No. 36373/54. Class 42 (1). In a method of fulling and felting textile goods the goods are conveyed with a progressive reciprocating motion through lines of rollers in rotatary fulling mills or through fullers of fulling stocks. As shown a rotary fulling mill consists of a frame 10 in which are mounted the main driving shaft 11 an upper line of rollers 12 and a lower line rollers 13. At each end of shaft 11 is mounted a crank disc 14, 15 which carry crank-pins 16 and 17. On crank-pins 16 and 17 are mounted connecting rods 42, 43 and 31, 32 respectively. These connecting- rods are connected by lever arms 38, 39, 24 and 27 to the journals of rollers 12, 13. The levers 38 and 24 are connected to the journals by ratchet drives 40 and 19 and the levers 39 and 27 by friction drives 41 and 20. The remaining roller journals are connected to the first by tie-rods such as 35 and 37 and are each provided with similar ratchet and friction drives. In operation, as the crank discs 14, 15 revolve the rollers are driven first in one direction by the ratchet drives (the friction drives slipping) and then in the reverse direction by the friction drives. By adjusting the length of the lever arms 27 and 39 (by means of the pin-and-slot connections 34, 33), the reverse drive can be made shorter or longer than the forward drive and hence the goods passing through the mill are given a progressive reciprocating motion which can be adjusted at will. The gap between the upper and lower rollers may be adjusted and the rollers may be given axial vibratory movements in the usual manner.
