Title: Signal Translator
IPC: G09G1/10
Filed: 1968-03-22
Abstract: 1,187,556. Cathode-ray tube displays. R.C.A. CORPORATION. 22 March, 1968 [12 April, 1967], No. 13900/68. Heading H4T. In an arrangement for producing graphical and alpha-numeric symbols on the screen of a cathode-ray tube some of the bits defining a symbol control the counting directions of a pair of bi-directional counters which count clock pulses and provide X and Y beam deflection signals, others of the bits pre-set a further counter which then counts down to zero under the control of clock pulses to provide a signal determining the length of the trace, a further bit controls the beam blanking and all of the bits control the overall operation of the system e.g. to produce a trace or to clear the system preparatory to receiving another symboldefining digital-word. Thus, as shown, the first three bits of a seven bit word in register 3 are decoded in Direction Decoder 5 and provide outputs L (left), R (right), U (up) and D (down) controlling the direction of counting of X and Y position counters 10 and 13 respectively. These counters, the outputs of which are converted to analogue form in converters 15, 17 and supplied to the X and Y deflection amplifiers 20, 22, count pulses, supplied via gates 13, 14 from a clock 12. When a symbol is to be traced the " Operation " output of a function decoder 25 supplied with all seven bits from register 3 " sets " a flip-flop 31 and the " 1 " output of the latter opens gates 13, 14 to pass the clock pulses to the counters 10, 11. The " 1 " output of flip-flop 31 also opens a gate 35 which then passes the last three bits of the word in register 7 to a length counter 36 which is preset thereby to a number indicative of the length of the trace and additionally the " 1 " output of 31 conditions a gate 40 to pass the middle bit of the word in register 7 to the beam intensity control 42 on the occurrence of a clock pulse. Length counter 36 is then stepped down on the occurrence of each clock pulse and when zero count is reached the output of 36 re-sets flipflop 31 so that gates 13 and 14 close and the beam deflection is terminated and gates 35 and 40 close and register 7 is cleared via OR gate 32. If the next digital word supplied to register 7 also indicates an " Operation " e.g. a continuation of the trace just produced, the cycle described is repeated. If, however, the next word indicates a clearance of the system preparatory to tracing a new symbol, function decoder 25 provides an " instruction " output which sets a flip-flop 30 the " 1 " output of which resets the X and Y position counters, clears register 7 via OR gate 32 and clears the display, by means not shown, via terminal 33. All symbols are traced as a series of spaced bright dots by the action of the clock pulses and the bright-up bit but the operation may be modified to produce a continuous trace. The CRT means 21 may include a storage scan converter tube producing output signals suitable for use by standard television receivers.

Title: Communication network
IPC: H04L29/08
Filed: 1975-04-07
Abstract: 1481581 Telegraphy INTERNATIONAL BUSINESS MACHINES CORP 7 April 1975 [12 April 1974] 14123/75 Heading H4P A communication network T 1  ... T 2  includes a device inserting and removing additional signals in a stream of digital elements. The device includes means for generating a set of additional patterns derived from P<SP>n</SP>-Z possible combinations of n digital elements each capable of assuming P values (Fig. 3 shows the case n=3, P=2, Z=0), the combinations being arranged in a predetermined cyclic order to provide P<SP>n</SP>-Z sequences each including n+P<SP>n</SP>-Z elements arranged so that the first n of these elements form one of the combinations and each of the subsequent elements forms, with the (n - 1) preceding elements, another of the combinations, the combinations formed successively from the subsequent elements appearing in the same order as the predetermined cyclic order. The device also includes means for interrupting the stream, means for selecting one of the sequences whose first n elements are the same as the n elements in the stream preceding the interruption, and means for inserting the last P<SP>n</SP>-Z elements of the selected sequence into the stream. Since the last n elements of the pattern are the same as the n bits preceding the interruption, the interruption may in fact take place up to n elements earlier. An additional pattern may be inserted in a previously inserted pattern, and an inhibiting element may be inserted when the stream contains a sequence of elements identical with P<SP>n</SP>-1 elements of one of the additional patterns. Means are also provided for removing an inserted pattern. Various types of pattern are discussed with reference to Figs. 4-10, 17 and 18 (not shown). Fig. 11 shows the device at a node X of the network. The stream is passed from receiver 219 to transmitter 218 via gates 202, 203 and a buffer 200, devices 209, 211 respectively detecting and generating additional patterns, and circuit 215 keeping track of the buffer positions containing a pattern; a switch 204 enables the additional pattern to be inserted. A comparator 214 compares counts in counters CR1, CR2 which indicate the elements read into or out of buffer 200 to determine the instant at which an additional pattern must be inserted or removed. Operation of this device is described in detail with reference to Figs. 12, 13 (not shown). Devices 209, 211 may be memories storing the additional patterns (Figs. 14 and 19, not shown) or they may be logic circuits which generate a pattern element by element (Figs. 15-18 and 20-25, not shown). Insertion and removal of the additional patterns may serve to compensate for variations in signal speed between the nodes X1, X2, ... of the network. They may be used to separate the successive portions of a message, or the characters within a message.

Title: Improvements in and relating to variable current generators
IPC: H01J40/14
Filed: 1922-05-20
Abstract: 180,343. British Thomson - Houston Co., Ltd., (Assignees of Hoxie, C. A.). May 20, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Vapour and vacuum or low-pressure apparatus, arrangements of.-Electric currents or voltages of any desired wave form are produced by subjecting a photo-electric device to light, and varying the quantity of light in accordance with the desired form of wave. In the arrangement shown, the photo-electric cell B comprises an exhausted tube in which metallic potassium is evaporated and allowed to condense on the walls, a barrier being provided to prevent condensation over a portion of the surface which is to serve as a window. The tube is " formed " by admitting hydrogen at a pressure of 100 microns and passing a current of about 33 milli-ampÞres, the potassium forming the cathode. The hydrogen is finally replaced by argon at a pressure of 12 to 200 microns. Light from a source A is caused to enter the cell through apertures 17 in a rotating disc 11 and through an aperture 14 in a fixed screen 12. The form of these apertures determines the variations of the amount of light entering the tube and the consequent variations in the current through the tube, while the frequency of the variations is determined by the speed of the disc 11. The shape of the aperture 14 may be such that the current variations follow a pure sine wave. The cell B is connected in series with a battery 18 and a resistance 19, and the current variations through the tube are amplified by a thermionic amplifier C, the grid circuit of which is connected to the terminals of the resistance, a few battery cells 23 being preferably included in the circuit. A pulsating-current of the desired wave form and frequency is thus obtained across the terminals 25, 26 of a resistance 24 in the plate circuit of the amplifier. If an alternating-current is required, the terminals 25, 26 are connected to the secondary of an air transformer, the primary of which replaces the resistance 24. Other means, such as rotating mirrors, may be used for varying the quantity of light entering the cell.

Title: Process of refining crude fats and fatty oils
IPC: C11B3/00
Filed: 1934-05-11
Abstract: Fats and fatty oils are purified by "breaking" with mineral acids, alkalies, or salts to remove mucilaginous and solid or colloidal matters, and then submitting to high vacuum short path distillation to remove free fatty acids and colouring matter as a first fraction and to leave a final residue of resinous and vegetable matter.  The treatment of linseed, cottonseed, ground-nut, palm, and whale oils is specified.  For example: (1) cottonseed oil is stirred for 1 hour at 80 DEG  C. with 0,1 per cent of 50 per cent caustic soda, the mucilage separated by settling, filtering, or centrifuging, and the clear oil distilled under a vacuum of 10<-3>--10<-4> m.m. of mercury in a still having the heating and condensing surfaces 1,5 cm. apart; the 5 per cent distilling off at 200--220 DEG  C. is dark coloured and contains the free fatty acids; the 90 per cent distilling at 250--260 DEG  C. is a water-white oil; the residual 5 per cent is a dark tarry mass.  (2) Cottonseed oil is broken by stirring for 1 hour at 70 DEG  C. with 0,1 per cent of 98 per cent sulphuric acid, the mucilage removed, and the oil fractioned as in example 1; 7 per cent distils off at about 210 DEG  C., 90 per cent at 250--260 DEG  C. Specification 415,088, and the prior treatment of cod-liver oil are referred to.

Title: Improvements in and relating to radar apparatus
Inventor: MILNE KENNETH
IPC: G01S7/02
Filed: 1956-05-09
Abstract: 1,081,971. Radar. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 6, 1957 [May 9, 1966], No. 14412/56. Heading H4D. To reduce the effect of a jamming signal on a radar receiver, the form of the jamming signal is determined, at the receiver, and the receiving circuit parameters are correspondingly adjusted, automatically, to reject the jamming signal. To prevent the simultaneous rejection of the target echo signal, the jamming rejection circuit is provided with a further control, the character of which depends on whether the radar is of the pulse or C.W. type. For a pulse system, the adjustment of the continuously adjustable jamming rejection circuit is discontinued by blanking signals from the receiver, during the time interval when the reflected pulse is expected. Thus, if the jamming signal changes slightly during this interval, only a small jamming signal will pass into the receiver. The required echo, on the other hand, passes freely into the receiver as the jamming rejector circuit is not now following changes in the antenna signals and is adjusted to reject only those existing on the antenna prior to the reception of the echo. For C.W. systems, the rejection circuit may be rendered insensitive to the required reflection frequency by the insertion of a band rejection filter tuned to the required echo frequency. The receiving aerial accepts, separately and simultaneously, two orthogonally polarized signals V and H and the adjustable phase shifters, I and II in the input channels A, B are adjusted by the automatic control signals from phase sensitive detectors I and II and effect the jamming signal rejection. The phase shifters may be reactance valves or goniometers.
