Title: Improvements relating to the treatment of fabrics and other sheet materials
Inventor: LANDELLS GEORGE
IPC: D06Q1/08
Filed: 1955-02-10
Abstract: <PICT:0791553/IV (a)/1> <PICT:0791553/IV (a)/2> A compressively shrinkable sheet material is ornamented by compressively shrinking it in contact with a second sheet material which buckles, the buckles so formed being transferred to the first material.  The compressively shrinkable materials include regenerated cellulose and plastic sheets.  The second material may be of paper, cardboard, a plastic, thin sheet metal, a fabric stiffened by a resin, starch or other agent, or a fabric so woven that it will not readily shrink, but tends to buckle if compressively shrunk alone.  The compressively shrinkable material may be of nylon, polyethylene terephthalate or other thermoplastic which may be heated during treatment to maintain the ornamentation or may be pre-treated with a temporary plasticizer or with an agent which will set by heat applied during or after the ornamentation or by a chemical reagent applied after the ornamentation.  The compressively shrinkable material may be disposed between two sheets of material which buckles during treatment, and compressive shrinking may be applied discontinuously over the surface.  As shown in Fig. 1, the compressively shrinkable material 16 is fed on to a thick rubber or like belt 11 passing around rollers 12, 13 at a point in advance of that at which the belt begins to contract, and the second sheet material 17 is also fed from a roll 15 into the nip between the belt 11 and a roller 14.  In the apparatus of Fig. 2, the compressively shrinkable material 23 and and the second material 24 are fed into an inlet nip between a roller 20 and an electrically heated bed plate 21, and emerge from an outlet nip formed by the roller 20 and a roller 22, the roller 20, which has a hard rubber surface, rotating faster than the roller 22, which has a soft rubber surface.  Discontinuous apparatus, e.g. a press, one face of which may be caused to contract in length, may also be used.

Title: Improvements in or relating to laminated glass sheets
IPC: C03B23/207
Filed: 1951-02-20
Abstract: 681,659. Laminated glass. KURZ, F. W. A. Feb. 20, 1951 [Feb. 22, 1950], No. 4160/51. Class 56. Laminated sheets of glass are formed by placing together side by side strips or layers 1, 2 of glass of a width greater than the desired thickness of the laminated sheet and of different colour and/or thickness, fusing the strips together to form a sheet 3 in which the strips are at right angles or an oblique angle to the surface of the sheet and stretching or drawing the sheet in a heated condition in the longitudinal direction of the strips to reduce the width of the strips and thus the thickness of the sheet. The strips may be cut and assembled in the dry state or liquid glass can be extruded or drawn from nozzles in the form of strips or layers disposed side by side. Thus thick and clear strips of glass may be combined with thinner strips of coloured glass of the same coefficient of expansion, or strips of two layer glass, e.g. flashed glass, may be used. The finished sheet may be rolled and ornamented by impressing rollers, thus parallel preferably prismatic grooves may be formed preferably at right angles to the laminations and coloured or enamelled or filled with paint or enamel. Alternatively coloured parallel strips may be provided on the ungrooved sheets. The sheets may subsequently be bent &c. The glass may be used for screening light, e.g. in luminous tube illumination, to subdue or distribute light, or to prevent dazzle, and with black laminations may be used in shop window illumination, or, with oblique laminations, as venetian blinds.

Patent GB-663612-A (GB)
Title: Improvements in and relating to pulse generating circuits
IPC: H03K3/16
Filed: 1945-02-22
Abstract: 663,612. Pulse generators. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 22, 1945 [Oct. 31, 1942], No. 4523/45. Class 40 (vi). In a pulse generator, a transformer provides positive feed-back between anode and grid circuits to produce blocked oscillations of considerable power, the output pulse being taken from a third winding on the transformer which has a very low leakage reactance and distributed capacity so that an approximately flat-topped pulse is obtained. The Figure shows valve 1 connected as a blocking oscillator with feedback from anode inductance 6 to grid inductance 7. The charging of capacitor 8 through winding 6 impresses a negative bias on grid 4 which becomes less as charging nears completion and finally allows the valve to conduct. Regenerative action then produces a rapid discharge of capacitor 8 and a high positive potential develops on grid 4. When the discharge rate begins to decrease, regenerative action drives 'grid 4 negative and cuts off valve 1, resulting in a positive pulse at the grid. Flow of grid current during the pulse period charges capacitor 11 to provide a negative bias on grid 4 between pulses, and resistor 12 determines the pulse recurrence frequency by controlling the leakage rate of capacitor 11. The pulses are fed to the utilization circuit through a tertiary winding 13 of the pulse transformer. Specifications 520,460, [Group XXXVIII], are referred to. The Specification as open to inspection under Sect. 91 describes a modification, Fig. 2 (Cancelled, not shown), in which an artificial delay network is inserted in series with the grid inductance to control the width of the positive pulse. Negative bias may be applied to the grid through the leakage resistor to hold the valve just below cut-off until it is rendered conducting by positive synchronizing pulses fed to the grid through a suitable capacitative coupling. In a further modification, Fig. 3 (Cancelled, not shown), a delay network is included in the grid circuit and synchronizing pulses are fed to the grid through a further winding on the coupling transformer. This subject-matter does not appear in the Specification as accepted.

Title: Controllable bandwidth if filter circuit for radio receivers
IPC: H03H7/12
Filed: 1976-02-06
Abstract: 1500123 Quadraphonic receivers GENERAL ELECTRIC CO 6 Feb 1976 [26 Feb 1975] 04694/76 Heading H4R In an IF filter circuit for use in a radio receiver capable of receiving broadcasts in the quadraphonic, biphonic or monophonic modes the filter circuit includes a number of tuned circuits connected together by capacitive coupling sections with the filter elements of the coupling sections being connectible into circuit by semi-conductor switching devices operated by a control circuit to vary the bandwidth of the filter circuit in accordance with the type of broadcast mode being received. Fig. 3 shows an embodiment of a filter circuit comprising tuned circuits 110, 112, 114, interconnected by capacitive coupling circuits 116, 118, and a control circuit 225 responsive to the presence or absence of the 19 kHz and 76 KHz pilot signals. During monophonic reception neither pilot tone is present, transistors 240 and 261 are cut off, extinguishing the LED stereo and quad beacons 239 and 259, and making transistors 230 and 244 turn off and transistor 256 turn on. If a stereo signal is received transistor 240 is turned on making diodes 146 and 192 conductive and increasing the damping on tuned circuits 122 and 186 so that the bandwidth of the filter is increased from 150 to 180 KHz. If a quadraphonic signal is received both transistors 240 and 261 will be turned on, transistor 230 will remain on, 244 will be turned on and 256 turned off. Turning off transistor 256 will make diodes 182 and 168 non-conductive which will increase the coupling between the adjacent tuned circuits 110, 112 and 114, by reducing the value of the shunt capacitors in the coupling circuits 116 and 118 from the values of capacitors 166 and 180 to the value of capacitance of an open circuit diode, i.e. by about a factor of 10. The change in coupling capacitance causes a change in tuning which is compensated by the switching on of transistor 244 which makes diodes 156, 172 and 198 conduct to connect capacitors 154, 170 and 196, in shunt with the resonant circuits via transformer windings 152, 174 and 200. In an alternative embodiment, Fig. 5 (not shown), change in bandwidth is effected by switching the damping on an input resonant circuit (330, 332) and varying the coupling capacitance between alternative values in capacitive coupling circuits 320, 322, 324, and 326.
