Patent GB-758677-A (GB)
Title: Electron storage tube
Inventor: HANSEN SIEGFRIED
IPC: H01J29/39
Filed: 1953-12-24
Abstract: 758,677. Charge-storage tubes. HUGHES AIRCRAFT CO. Dec. 24, 1953, No. 35927/53. Class 39 (1). A storage grid assembly comprises a conductive mesh screen 73, a layer of dielectric material 72 disposed on one side of the screen and coextensive with the meshes thereof, and a second screen 77 in contact with the dielectric material on the other side, whereby portions of the dielectric material exposed within the interstices of the screen 77 form the storage surface. A high-velocity scanning beam from writing gun 21 lays down a positive charge pattern on the grid assembly, while a broad low-velocity beam from gun 11 floods the assembly and the electrons which penetrate the apertures thereof pass on, modulated in accordance with the charge condition at each aperture, to luminescent screen 82 which gives a visual representation of the charge pattern. The charging occurs by collection by screen 77 of electrons arising both from secondary emission and from bombardment-induced conductivity, in unstated proportions, and the " effective secondary emission coefficient " of the material 72, including both these phenoma, must exceed unity over a range between two critical potentials. As the first critical point V o  is unstable, any parts of the storage surface which are above this potential are increased by the bombardment of the flooding electrons to the second critical voltage V c , which is the voltage of screen 77, while any parts below this potential fall to cathode voltage. If V c  is greater than 2V o  this pattern will persist indefinitely and can only be erased by momentarily reducing the potential of screen 77. Thus a " black and white " pattern is rapidly produced which may be used in radar to enhance the intensity of target echoes over the noise level; in this case by choosing V c  to be 1.3V o  it can be secured that the flood electrons gradually " shrink " the white areas so that they disappear in a time of several scanning periods, so that moving targets can be depicted. The main lens of the flooding gun is provided by wall coatings 62, 64, the latter being connected to grid 73 at - 10 volts while 62, anode 14 and high potential electrodes 30, 36 of the writing gun are all at +1,000 volts. The flooding cathode 12 is earthed. The intermediate electrode 34 of the writing lens is at - 300 volts and the writing cathode 22 is at - 700 volts. Grid 73, Fig. 3, is a stainless steel wire cloth with a pitch of 0.004 inch coated with a protective glaze 74, Fig. 1, on the gun side. The material 76 may be a phosphor such as willemite, zinc sulphide or calcium tungstate. Collector grid 77 may be an electro-deposited nickel or aluminium mesh of pitch 0.01 inch. The phosphor 91 is de. posited on a conductive layer 89 of stannous oxide which is kept at +3,000-10,000 volts.

IPC: G09B21/02
Filed: 1968-07-29
Abstract: 1,209,376. Embossing surfaces. ROLLSROYCE Ltd. 14 July, 1969 [29 July, 1968], No. 36085/68. Heading B6C. [Also in Division B3] Movement of a tracer 15 (Fig. 1, not shown) over a pictorial representation such as a drawing causes identical movement of a sheet 32, Fig. 3, between a punch 34 and die 35, the punch and die being actuated so that a copy of the original is produced on the sheet 32 in dotted or other interrupted form. The sheet 32 may be a zinc sheet which may be used as a master sheet for embossing manilla paper to produce copies which can be "read" by blind persons. The punch may carry a character instead of a dot. A spring-return pneumatic ram 42 operates the punch 34 under the control of a shuttle valve actuated by a solenoid 43, Fig. 2. The solenoid 43 is connected to an electronic control system 45 which is also connected by lines 50 to a copper ring 49 and to a conductive rod 46 suspended from a swivelling bearing 51 and extending through the ring 49. A rubber diaphragm 47 or spring means normally holds the rod 46 centrally of the ring 49 with a foot 62 pressing on a rubber sheet 63 connected to the tracer. When the tracer is moved, the sheet 63 moves the rod 46 so that it makes contact with the ring 49 to cause the solenoid 43 to be operated for a predetermined time to actuate the punch 34. The bearing 51 is carried by a bell-crank lever 54 pivoted to the armature 58 of a normally energized solenoid 55. Closure of the circuit 50 by contact of the rod and ring 46, 49 causes, through the control system 45, the circuit of the solenoid 55 to be broken for a predetermined time. With the solenoid 55 inoperative, the diaphragm 47 can raise the rod 46 from contact with the sheet 63 and centre the rod so that the current of the solenoid 43 is broken. The solenoid 55 is now re-energized to restore the parts to their original positions ready for a further cycle of operations. A predetermined movement of the tracer causes a predetermined number of separate punch marks on the zinc sheet. The vertical position of the ring 49 may be adjusted to vary the spacing of the punch marks.

Title: Improvements in or relating to the treatment of coir fibre
IPC: D01C1/02
Filed: 1934-12-17
Abstract: Artificial horsehair is produced from the cheaper unspun coir fibre, e.g. that known as mattress fibre and similar fine fibres, by boiling the fibre in an alkali solution at a pressure above atmospheric pressure, drying and curling by passing it through a teasing machine having a clothing of fine teeth on swiftly rotating counterworkers, each fibre being curled by its passage several times over teeth over which it is drawn as over the back of a knife.  Bales of fibre are opened in a shake willey and the fibres then boiled in a bath of 2--3 per cent caustic soda for two or three hours at 30--40 pounds per square inch.  The fibres are then washed in a scouring machine, dyed if desired, squeezed through rubber rollers and dried in a current of warm air.  During drying, the fibres may be rubbed together and curl is then imparted to the fibres in a teasing machine.  Specification 328,638, [Class 120 (iii)], is referred to.

Title: Radio receiver
IPC: H03F1/30
Filed: 1962-09-24
Abstract: 944,550. Transistor radio receivers. BENDIX CORPORATION. Sept. 24, 1962 [Oct. 4, 1961], No. 36288/62. Headings H3T and H4L. In a transistorised car radio receiver the R.F. stage 192, to the base of which A.G.C. is applied, is biased by means of a resistor 204 connecting the base to a D.C. load 206 in the collector circuit. Other features of the receiver, which is specially arranged to reduce ignition interference and also the feedback of harmonics from the output of the I.F. amplifier and detector into the R.F. stage comprise the aerial coupling circuit, which is a transformer 184, 188 with inductively tuned primary circuit 184. A small inductance 186 in series with the aerial reduces ignition interference. The operating point of the I.F. stage 248 is stabilized by means of D.C. feedback, the collector circuit including a resistive load 256 which is back-coupled to the base over resistors 254, 252. The positive supply line 197 is smoothed by means of resistors 304, 306 and capacitors 308, 310; the A.G.C. diode 282 is connected at one end to this line and at the other by capacitor 274 to the collector of the I.F. stage 248, A.G.C. being applied to the controlled R.F. and I.F. stages over a filter comprising resistors 278, 284 and capacitors 280, 194. The two lines 276, 197 leading to base and emitter respectively of the R.F. stage 192 are held at the same A.C. potential by means of capacitor 194, so reducing the effect of interference. The audio amplifier comprises directcoupled cascaded PNP, NPN and PNP stages 300, 320 and 338 respectively, with overall A.C. negative feedback between the speech coil of the speaker and the input of transistor 300 by way of resistor 348. The base of transistor 300 is biased by means of a potentiometer comprising resistors 312, 314 connected across the unsmoothed supply. The input is derived from a detector circuit comprising the secondary of I.F. transformer 268, diode 290, filter network 287, 291, 289 and volume and tone controls 294, 295 respectively, the arrangement being such that any ripple in line 297 which is impressed upon the base of transistor 300 also appears on line 292, i.e. at the emitter, and so is ineffectual. Resistor 304 has a positive temperature coefficient and operates above ambient temperature; being self-heating it compensates for change in amplifier current.
