Patent GB-838187-A (GB)
Title: Improvements in or relating to apparatus for cutting plate glass produced in a continuous ribbon
Inventor: KNAFF ALBERT
IPC: C03B33/037
Filed: 1958-06-20
Abstract: 838,187. Cutting glass. SIEMENSSCHUCKERTWERKE A.G. June 20, 1958, No. 19848/58. Class 56. Apparatus for cutting glass as it is produced in a continuous, travelling ribbon 1 comprises a cutting device 3, 4 or 5 provided at a first zone 2 adjacent the travelling ribbon and constructed to cut the glass tranversely whilst the ribbon is travelling past, there being a control station 7 situated adjacent the travelling ribbon at a second zone which is spaced from the first zone and is before it (having regard to the direction of movement of the glass) and control means 8 provided at said control station and so constructed and so associated with the cutting device that they determine the locations on the ribbon where the latter will subsequently be cut at said first zone, said control means being operable automatically such that a pre-determined fixed length of glass will separate two successive locations which are determined as aforesaid, and said control means also being operable manually, at the will of the operator, such that an arbitrary length of glass which may be chosen by the operator will separate two successive locations which are determined as aforesaid. The arrangement allows the cutting out and isolation of faults from the cut sheets. The. cutting devices travel with the ribbon as they move across thus avoiding skew cuts. The scored sheet may be broken by an eccentric roller 6. The control station includes an impulse generating device 9 and a sight line 10 extending at right angles across and slightly above the plane of the ribbon and formed by a light ray. The impulse generating device includes a ground driving disc which engages the ribbon and is frictionally rotated as the ribbon passes. This disc drives a light-controlling disc carrying photographic film on which are closely spaced light permeable and light-impermeable regions. Thus current impulses are emitted by a photo-electric cell at a frequency proportional to the speed of travel of the ribbon and these impulses may be stored and counted so that when a pre-set number of impulses has been received by the counter the cutting device associated therewith is actuated. The counter may be set by a keyboard or punched cards. A plurality of counters and associated cutting devices may be utilised, the operator selecting at will by push buttons the length of glass to be cut. A further counter for continuous observation may be provided to allow the correct selection of cutting length should a fault be found in the ribbon. A smaller number of current impulses per unit length may be employed with this counter than with the others, and in this case slot on the light control disc may have a correspondingly larger spacing. After the position of any cut has been determined, both the counters for the set cutting lengths and the counter for continuous observation should return to the zero position.

Title: Improvements in or relating to circuit arrangements for stabilizing a saw-tooth current through a coil and a resultant pulsatory voltage
IPC: H04N3/185
Filed: 1959-06-10
Abstract: 921,708. Automatic control systems for line scan generators. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 10, 1959 [June 13, 1958], No. 19876/59. Class 38 (4). [Also in Group XL (c)] The line scan current and E.H.T. voltage output of a line scan output circuit are stabilized by biasing the output amplifier valve in accordance with the amplitude of a pulse derived during a selected portion of the flyback period. It is shown that during the flyback period the voltage across the primary of the line output transformer and the voltage applied from the secondary of the transformer to the E.H.T. rectifier each have one or more peaks due to high-frequency components. The first peak to occur on the secondary side causes the E.H.T. rectifier to conduct and therefore is subject to variable damping depending upon the E.H.T. load. This damping also reduces the amplitude of the high-frequency components on the primary side so that the next peak in the primary voltage which follows the time of conduction of the E.H.T. rectifier is considerably reduced in amplitude. It is this peak which is measured to provide the control signal. For the first embodiment it is assumed that the primary voltage has a double peak, the second one being measured, and the secondary voltage a single peak. The line output valve 22 energizes an auto-transformer 19 which supplies the scanning coils and the E.H.T. rectifier 16. There is a booster diode 45. A triode 17 is biased by the difference between a fixed voltage from a discharge tube 35 and voltage pulses tapped off the primary of the transformer 18. The triode could therefore conduct on either the first or the second peak of the primary voltage. It is, however, prevented from responding to the first peak by supplying the anode from an auxiliary winding 27 on the transformer 19 through a differentiating network 29, 30. The time constant of the network is such that the anode voltage only becomes positive during the second half of the flyback period. The pulsatory current of triode 17, smoothed by capacitor 32 provides a negative control bias for the line amplifier 22. In a modification, Fig. 5 (not shown), the voltage pulse applied to the grid of triode 17 is integrated so that it only exceeds the fixed voltage of the discharge tube 35 during the second half of the flyback period and the pulse is also applied to the anode. This arrangement may also be used, by reducing the fixed voltage, when the anode pulse to be measured occurs earlier in the flyback period, i.e. when the primary voltage only has a single peak. It is stated that the triode 17 may be replaced by a diode or a transistor. Specification 723,510 is referred to.

Title: Thin film capacitor and method of making the same
IPC: H01B3/00
Filed: 1964-05-15
Abstract: An electrically conductive film may be formed from a mixture of gold resinate, powdered glass, and an organic screening agent such as ethyl cellulose, the mixture being screened on to a substrate such as alumina and fired at a temperature above the melting-point of the glass but below that of the gold to drive off the organic vehicles and fuse the glass.  Platinum may be used instead of gold.  A glass-bonded dielectric layer may be formed on the conductive film from a mixture of at least one organo-metallic compound, e.g. a tantalum resinate, with resinates of lead, boron and silicon; the latter resinates will produce glass, and when firing in an oxidizing atmosphere the organic materials are driven off, the tantalum oxidized to form tantalum pentoxide, and the glass molecularly bonds the tantalum pentoxide particles to each other and to the conductive film.  The dielectric forming metal may be titanium, zirconium, tantalum, tungsten, hafnium or niobium, and may be reacted with barium, calcium, strontium, copper, nickel, lead or tin to produce a desired dielectric characteristic such as independence of temperature or frequency.  A further conductive film bonded to the dielectric layer may be formed as the first film.

Abstract: 722,756. Spinning yarns ; crimping threads and filaments. IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 17, 1953 [Aug. 13, 1952], No. 20337/52. Drawings to Specification. Class 120 (3). Artificial threads or filaments are crimped (the latter during or after drawing) by passage over a deforming edge, under tension, with simultaneous rotation about their longitudinal axes. The rotation may be caused by applying a lateral force to the filamentary material as by so guiding the material that the plane containing its path before and after passing over the edge is oblique thereto and the paths before and after contacting the edge are positioned at unsymmetrical angles thereto, or the edge may be moved as by reciprocation or rotation so that it imparts a rolling action to the material. The edge may be straight, convex (which may necessitate the use of thread guides to maintain the material in contact with the edge) or concave, which latter two forms may be provided by the peripheral surface of a rotating disc or'the inner surface at one end of a rotating tube through which the material passes. A bundle of artificial filaments may be spread into a ribbon, crimped by the process of the invention, subjected to an air blast to disturb the filaments, and then twisted to a form resembling worsted yarn.

Inventor: DAVIES DONALD WATTS
Filed: 1950-08-16
Abstract: 682,998. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 11, 1951 [Aug. 16, 1950], No. 20371/50. Class 106 (i). [Also in Groups XXIV and XXXV] An electromagnetically - operated device, applicable to digital calculating machine, for producing longitudinal displacements of a rod 11 in equal steps comprises a preferably horizontal plate 1 supported at points 2, 3, 4 by levers 5, 6, 7. The levers are operated by electromagnets 10 and the vertical rod 11 is attached to the plate 1 at the centroid of triangle 2, 3, 4. The levers 5, 6, 7 and their electromagnets are arranged to cause upward displacements of one, two and four units respectively of the plate 1. Set-screws limit these displacements and the levers are returned by springs. The under surface of the plate has slots 15 to receive locating members. By operating the electromagnets in appropriate combinations the rod 11 may be raised by any amount from 0-7 units. In a modification, Fig. 4, a rod 32 is attached to a triangular plate 31 at the centroid of masses 1, 2 and 4 units placed at the apices, and the apices may be given equal downward displacements, against a spring 30, by solenoids 40, 41, 42. The longitudinal movements of the armatures 43 are limited to the same value by set-screws 39A, 39B. In general, if the displacements permitted at three points are a, band c units, the rod is attached at the centroid of masses 1/a, 2/b and 4/c placed at the three points respectively. Displacements of from 0 to 15 units may be obtained by allowing the whole device to be displaced by 8 units. For a calculating machine the rod 11 could be fixed to a recording head for a magnetic storage device, and the electromagnets be operated through staticisors by a coded signal. According to the Provisional Specification, a member equivalent to the plate 1 may be moved at only two points, and it is stated that a cascade of displacing devices may be used.
