Title: Method of coding for facsimile transmission
IPC: H04N1/419
Filed: 1974-06-06
Abstract: 1466282 Data transmission; facsimile systems; methods of coding HASLER AG 6 June 1974 [8 June 1973] 25284/74 Heading H4P In a method of coding for facsimile scanned lines, successive points of equal brightness are counted and code words of varying length are allocated to numbers of points such that longer words correspond to greater number of points and each word of at least one brightness consists of one or more groups each of constant length and comprising two parts, the first part indicating brightness and the combination of second parts being formed by adding 1 to the number of points, the sum being in binary code, and then omitting the most significant bit=1; the number of groups is chosen so that the second part of the group allocated to the most significant bit or bits contains a 1. The group length may differ for different brightness values. In Fig. 1 (not shown) the first bit c indicates black/white significance followed by 2 information bits. The number of groups and the information bits together form a combination which determines run length upon reception. Fig. 2 (also not shown) has only one information bit per black/white bit. In the limiting case each group consists of one bit = original bit; the code may be different for black/white. At the transmitter, a signal is passed to controller 5 at the end of each line of 0/1 bits from scanner 1 fed into shift register 2 causing serial read out to coder 20 which includes a run length counter 10, which is reset at each bit change with the count dumped into shift register 12. This corresponds to operation as described in copending application No. 25283/74. In the present arrangements, circuit 21 produces a code word from the counter, and assuming two bit groups, a colour indicating bit from flip-flop 17 and a count bit from register 12 are transmitted. Timing is controlled by a clock 22 and divider 23. As soon as the most significant bit reaches the last stage of register 12, decoder 14 through inverter 28 blocks gates 25, 27 and signals controller 5 that code word transmission is complete, i.e. the most significant bit is not transmitted. The receiver (Fig. 4, not shown) is approximately a "mirror image" of the transmitter plus a clock pulse extraction circuit. Received signals are passed into a register (34) connected to a read only memory (39) and down counter (40) through gates (not shown). Another counter (64) is reset at each brightness change thus serves to ascertain the number of groups in a code word. Before reset, counter (64) reading is transmitted to ROM (39) which determines the number of groups and associated number of points from the code word which are passed into counter (40) and thence to a register (45) and to a writing device (45). Advantage of the arrangement is stated to derive from the fact that the code word is approximately proportional to the logarithm of the run lengths.

Title: Improvements relating to saccharides and compositions thereof
IPC: A61Q19/00
Filed: 1962-07-03
Abstract: A saccharide extract is obtained by peeling and dicing sprouts of cactus opuntia vulgaris, leaving the dried particles in water until they are swollen and form an aqueous extract, separating the particles from the aqueous extract and subjecting them to a second extraction with water, comminuting the particles with water after separating from the second extract, allowing the comminuted mixture to stand until a glutinous layer forms, separating this layer, filtering the solids from the liquid remaining to obtain additional extract and drying the several extracts.  The process is preferably carried out with water at a temperature of 10-35 DEG C. The aqueous extracts should preferably be dried at a temperature not exceeding 45 DEG C.ALSO:A saccharide extract produced from cactus optuntia vulgaris is used in the preparation of cosmetic compositions.  These compositions comprise a stable oil-in-water emulsion in which the discontinuous phase may comprise a solution of mineral and beeswax and the continuous phase is an aqueous solution containing the saccharide extract.

Title: Improvements in and relating more especially to tariff meter apparatus
IPC: G07F15/08
Filed: 1934-09-08
Abstract: 431,611. Prepayment mechanism for meters; counting-apparatus. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Sept. 8, 1934, No. 25880. Convention date, July 19. [Class 27] [See also Group XIX] In apparatus comprising a number of stepping mechanisms operatively connected together in series for adding together the effect of a corresponding number of different m o v e - ments identified with different values, the total movement being conveyed to a registering or prepayment mechanism, the different movements are each transmitted by a separate toothed actuating wheel and actuator element to the respective stepping mechanism. As applied to a prepayment electricity meter mechanism, the planet wheel 21 of the usual epicyclic mechanism 17, 19, 21 for operating the switch controlling device 22, is set forward by the coin mechanism 20 and returned by rotation of the sun-wheel 17 by a spring 23 under the control of a meter driven wheel 1 and a wheel 2 driven by a flat rate motor. The actuating wheels 1, 2 produce respectively oscillating movements of actuator levers 3, 4, the lever 3 being formed with a pronged escapement pawl 5 engaging teeth 6 of a wheel 7 on the shaft of which is slidably but non-rotatably mounted a bracket 10 having pins 11, 12 coacting with a wheel 13 driven by the spring 23 to form a second escapement. Rotation of the wheel 1 releases the wheel 7 for step-by-step movement, the spring 23 driving through the wheel 13, pins 11 or 12, bracket 10 and shaft of wheel 7. The bracket 10 has a collar 9 engaging a squared portion 14 of the shaft of wheel 7 and is reciprocated vertically by a fork 8 of the lever 4 when this is rocked by the wheel 2. At each oscillation, the wheel 13 is released to rotate step-by-step under the action of the spring 23, so that the sum of the movements of the wheels 1, 2 are transmitted to the sun-wheel 17. The wheels 1, 2 may be arranged to drive the stepping mechanisms positively, the spring 23 being dispensed with. Price-changing mechanism.-Exchangeable screening discs 25 with cut-out portions 24 may be applied to the wheels 1, 2 to vary the effective number of teeth on these wheels for price changes. If the wheels 1, 2 are pin wheels, the number of oscillations of the levers 3, 4 per revolution of the wheels may be altered by screwing pins in or out of the wheels.

Filed: 1967-06-06
Abstract: 1,136,691. Transistor pulse circuits. AMERICAN MACHINE & FOUNDRY CO. 6 June, 1967 [23 Aug., 1966], No. 25978/67. Heading H3T. [Also in Division G3]  Apparatus for regulating the frequency of a rotary inverter comprises a bi-stable multivibrator the output of which is a sawtooth waveform whose magnitude represents the difference in phase between the inverter output and a reference signal which is generated by division of the output of a transistor maintained tuning fork. The tuning fork circuit is shown at 60, and includes feedback via resistor 102 and an RC circuit 104, 106 which, combined with no impedance in the emitter of output transistor 100, ensures rapid start-up. The divider circuit 110 comprises a capacitor 142 which is charged by successive pulses on input capacitor 64 and resistor 140 is adjusted so that a unijunction transistor 130 is triggered on the required pulse (e.g. the eighth). The output 118 is connected to the reset terminal of the bi-stable multivibrator (Fig. 2, not shown), which is set by pulses derived preferably by division of the controlled frequency. The multivibrator alternately charges and discharges a capacitor (48) connected to a transistor (34) whose output is thus a sawtooth waveform which overrides the frequency reference in a retractive control system by which the fields of an A.C. generator and its D.C. driving motor are regulated. The multivibrator also filters out transients. In Fig. 4 (not shown), a similar frequency divider is preceded by a clipper using a series resistor and shunt Zener diode.
