Title: Pcm tdm telecommunications systems
IPC: H04Q11/08
Filed: 1973-08-09
Abstract: 1433003 Automatic exchange systems SIEMENS AG 9 Aug 1973 [11 Aug 1972] 37822/73 Addition to 1402506 Heading H4K In a PCM, TDM system wherein a data transmission may be divided among several time slots in the same frame at the transmitting end, a number of different sections of an exchange are coupled to a 4-wire TDM highway via crosspoint switches and each section is connected to the switches via an outgoing intermediate store/buffer store arrangement operating in the manner described in the parent Specification and serving to collate received information relating to a data transmission according to the frame in which it was transmitted so as to compensate for the different frame delays incurred by the information in different time slots during the passage of the information through a multi-exchange system. The exchange has four sections 2KF, 4KF1-3 (section 4KF2 is not shown) and each section may be used for different types of transmission. Section 2KF is a two wire crosspoint switching network for speech connections which is coupled to an incoming/outgoing TDM highway An/Ab via crosspoint switches KS and a modulator/demodulator Mo/Dem. Sections 4KF1-3 are four wire crosspoint switching networks for data connections. one or more of which may be associated with video-phase connections and each section, e.g. 4KF1 is connected with the incoming highway An via an incoming intermediate store pair 1Sana, 1Sanb, a further store 01 and a crosspoint switch 1Kzb and is connected with the outgoing TDM highway Ab via outgoing intermediate store pair 1Saba, 1Sabb and a crosspoint 1Kza Under the control of addresses circulating in stores Ua, Ub information is read to and from the TDM highway An, Ab by the operation of the crosspoints KS, 1Kza-3Kza, and 1Kzb- 3Kzb, the function and operation of the buffer store 01-03 and the intermediate stores 1Sato 3Sa-being substantially as described in the parent Specification. The intermediate stores are shift registers having one storage location for each of a maximum of six time slots (only five locations being shown in the drawing) amongst which a data transmission may be divided in one frame and each storage location has a capacity of 8-bits. As different transmission rates require the use of differing numbers of time slots per frame it is necessary to provide a choice of clock frequencies via switches 1SchT-3SchT for stepping the shift registers. Further, although the inputs and outputs of the shift registers are shown as being at the first and final stages, where less than five times slots are to be used the input or output of the register may be shifted automatically to give a corresponding number of storage locations therebetween.

Title: Circular light polarizer
IPC: G02B5/30
Filed: 1960-11-03
Abstract: 933,252. Circular light polarizers. INTERNATIONAL POLAROID CORPORATION. Nov. 3, 1960 [Nov. 16, 1959], No. 37839/60. Class 97 (1). A circular light polarizing film comprises a complex with a dye of oriented macromolecules of a polypeptide which have a helical configuration, which polypeptide is derived from an optically active α-amino acid. The polypeptide may be a synthetic poly-α-L-glutamic acid, which exists in a helical conformation below pH 4.9. Such an acidic polypeptide may be used as a complex with a basic dye such as Acriflavine Neutral or Rhodamine 6G. Alternatively, a basic polypeptide such as poly-α-L- lysine may be used with an acidic dye. A solution of the polypeptide/dye complex may be cast or extruded into a film and oriented by stretching or rubbing. A plurality of such oriented films may be laminated together and thin transverse slices cut to provide a polarizing film with the molecules oriented perpendicular to its width. Alternatively, a viscous solution of the complex may be passed along a tube and then rapidly solidified at a selected stage when the molecules are oriented. Transverse sections are then cut from the tube. In a further method, a viscous solution of the complex is cast on a plane surface, either as a temporary or permanent support, subjected to an electric field to orient the molecules and then dried rapidly.

Title: Motor vehicle safety and/or warning devices
IPC: G01P15/18
Filed: 1974-08-29
Abstract: 1457368 Accelerometers; counting infractions of limits H M HENDERSON 29 Aug 1974 [13 May 1974] 37907/74 Heading G1K Apparatus to record and/or to warn a vehicle driver of the occurrence of excessive acceleration, braking, or cornering speed, comprises a circuit including at least one switch 1, Fig. 1, or 15, Fig. 3, which is closed when it is subjected to a predetermined acceleration, a counter 11, Fig. 1, or 22, Fig. 3, and/or a warning emitter 24, and a timing device 28 which allows actuation of the counter and/or the warning emitter only after the switch has been closed for a predetermined interval, preferably 0À1 to 0À5 second. The delay is to prevent spurious actuation of the counter or warning emitter due to jolting of the vehicle. In Fig. 1, four inclined mercury switches 1 face in four directions spaced at 90 degree intervals to be responsive to forward acceleration, forward deceleration, centripetal acceleration in a left turn, and centripetal acceleration in a right turn, respectively. The inclination of each switch, and thus its triggering acceleration, is adjustable by turning a respective knob 6. Other forms of inertia switch may be used. The switches are designated 15 in the circuit diagram of Fig. 3. When a switch is closed, following the interval needed to charge a capacitor 28 transistors 18-21 are fired in sequence to advance the counter 22 one step and/or to cause an oscillator circuit 23 to drive a speaker 24 to emit an alarm signal. The oscillator 23 is powered by a capacitor 29 so that the alarm sounds for only about one second. The second transistor 19 will fire only if a capacitor 25 is charged. As this takes about 4 seconds to change, the system cannot be actuated more frequently than every 4 seconds.

Title: Data terminal-computer interface system
IPC: G06F1/08
Filed: 1971-08-13
Abstract: 1311076 Interfacing computer and peripherals TEKTRONIX Inc 13 Aug 1971 [20 Aug 1970] 38029/71 Heading G4A [Also in Division H4] An interface for use with a computer and a data terminal includes transmit and receive registers for both the computer and the terminal, the registers being arranged to communicate with each other in serial and with the computer and terminal (as appropriate) in parallel, the arrangement being that the transmissions are controlled by one of two clock sources 30, 32, of different frequency, the low frequency clock 32 being used in response to the transmission of data to the computer and the high frequency clock 30 otherwise. As described, data being transmitted to the computer is sensed by a device 36 which may include a monostable multivibrator. The low frequency clock is connected to the registers by a switch 34 in response to a data bit being transmitted to the computer for a period determined by the multivibrator. If at the end of that period no further data bit is sensed the low frequency clock is replaced by the high frequency clock. The period is set so as to give time for a received word to be cleared from the interface register 38 into the computer. In a modification, register 38 is clocked by a separate clock generator having a frequency similar to that of the low frequency clock 32. The data received by the computer may be immediately retransmitted back to the terminal via register 42 for error checking and/or printing. Since the terminal can receive original data from the computer at the high clock frequency the fact that the data being retransmitted is transmitted at the low frequency or partially at the low and partially at the high frequency (i.e. when a transmission to the computer ends before the retransmission ends) is of no significance. The data transmitted includes a start bit which when sensed by the multivibrator 36 selects the low-frequency clock, a number of data bits, an even parity bit, and two stop bits. The terminal is arranged to produce a busy signal on line 46 when it is occupied, this signal being used to prevent any clocking pulses being delivered to the clock line 18.

Title: Method and apparatus for coating loose particles with a sprayable bonding substance
IPC: B27N1/02
Filed: 1960-11-08
Abstract: In a method for coating loose particles by spraying a bonding substance on to measured quantities of particles falling in the form of a veil, a supplementary acceleration in a downward direction is imparted to the particles before they reach the spraying zone.  As shown, particles 1 are fed by a vibrating trough 2, strike <PICT:0907697/III/1> a baffle 3 and fall on a distributing cone 5 arranged in a funnel 4.  The particles are then accelerated downwardly and given a rotary motion by blades 13 which are mounted on a shaft rotated by a motor 9, and then enter a chamber 14 in which they are sprayed, while falling, with bonding substance by spray-guns 21.  They then fall into a double-trough transporter having two shafts 15 (not shown) and 16 driven in opposite directions, and carrying impeller arms 17 (not shown) and 18 which stir the particles and convey them towards a discharge opening 26.  Air and bonding material mist are drawn off through an outlet 25, the air being caused to pass through the upper part of the moving particles by a baffle 24.

Title: Process of preparing a compound fertilizer, containing nitrate of ammonia and dicalcium phosphate, from sedimentary phosphates
IPC: C05B11/06
Filed: 1957-12-10
Abstract: A process for preparing a compound fertilizer containing ammonium nitrate and dicalcium phosphate comprises decomposing a mineral sedimentary phosphate e.g. Kouribgha Florida pebble or Egyptian phosphates with 50 to 65% nitric acid, removing calcium nitrate from the solution by coating and crystallization to leave a mather liquor having a molar CaO/P2O5 ratio of 1,6 to 2,6, diluting this liquor with water and/or nitric acid to lower the P2O5 content to below 15% by weight, neutralizing the diluted liquor with ammonia, evaporating and granulating the resulting melt.  This process, particularly the diluting step, reduces the tendency of neutralized liquor to become more viscous and unworkable during the subsequent evaporation stage. Specification 692,251 is referred to.
