Abstract: 1,239,563. Vehicle brake testing. SOC. ANON. FRANCAISE DU FERODO. May 13, 1969 [May 20, 1968], No.24287/69. Heading G1W. A test stand for brake testing vehicles comprises a reference frame 13, a floating frame 12 adapted to carry a roller 11 and having three degrees of freedom for small displacements of the floating frame relative to the reference frame along three orthogonal axes and strain gauges for measuring the forces on tie bars 75, 85 interconnecting the frames. The frames 13 are arranged in pairs to form cradles 14A, 14B, having wheels 15 and nuts engaged with screw threaded rods 19 rotated by motors 16A to enable the cradles to be relatively displaced. Each frame 12 consists of members 37-40, the member 37 having lugs 41-43. A horizontal dynamometric balance 45 comprising a pair of levers is articulated to the lugs 41, 43 and the tie bars 85 extend between the frame 13 and the balance 45. The common pivot of the levers which comprises a portion of the balance of reduced thickness is connected to the lug 42 by a member carrying an electrical strain gauge. Vertical dynamometric balances 60, 62 are connected at their ends by the tie bars 75 to the frame 13 and their central common pivots of reduced thickness are connected to the members 37, 38 by members such as 61 each bearing an electrical strain gauge. The frame 13 is additionally connected to the frame 12 by a link 92 carrying an electrical strain gauge. Each vertical balance 60, 62 is connected to the member 37, 38 by an additional adjustable tie rod (95) Fig.3 (not shown) to enable a zero setting of these balances to be made without a vehicle on the rollers. Shafts on which the rollers are mounted are rotated by shafts 120 coupled by universal joints 121 to pulleys 122. Pairs of pulleys are connected by belts 123 and gear-boxes 131 enable the employment of flywheels 130. The resultants of the vertical forces to which the pairs of tie rods 75 are subjected are measured by the balances 60, 62 and their associated strain gauges. The summation of these two resultants provides the vertical component of the force F acting on a roller whilst the components of the force F in the other two orthogonal directions are determined by the strain gauges associated with the balance 45 and the link 92. The shaft of one of the rollers of each roller pair is coupled to spokes within the hub of the adjacent roller, which spokes may be withdrawn from the hub by an hydraulic device to enable decoupling of the adjacent roller when dismantling or assembling the rollers.

Abstract: 1,257,855. Carbon black. PHILLIPS PETROLEUM CO. 21 July, 1969 [22 July, 1968], No. 36633/69. Heading C1A. In the formation of carbon black by the pyrolysis of a hydrocarbon feed, the feed is mixed with a first quantity of hot gas to effect dilution and dispersal of the hydrocarbon feed throughout said gas, the temperature of said gas being sufficient to raise the temperature of the feed to a point which is below that at which carbon black is formed and within 600‹ to 1200‹ F. thereof then a second quantity of hot gas is added to the resulting mix to raise the temperature to the temperature at which carbon black is formed, the hot gaseous mass so formed being passed to a zone in which the carbon black is formed and recovering the black as product from the effluent of this zone. The hot gas is preferably a combustion gas obtained by burning a fuel in the presence of a free oxygen containing gas. The first quantity of combustion gas may be formed using an oxygen containing gas containing less than the stoichiometric amount of oxygen required for the complete combustion of the fuel and for the second quantity of combustion gas the free oxygen containing gas may contain more than the said stoichiometric amount of oxygen. Preferably the amount of free-oxygen containing gas used in the first combustion is 2-30% of the total free oxygen containing gas used in the process. In the first heating step the temperature is preferably raised to 1300‹ to 800‹ F. below the lowest carbon black formation temperature for that particular feed. The lapse of time between mixing the first and second hot gas streams may be 0À0025 to 0À010 seconds. The feed may be introduced into the upstream end of an elongated generally cylindrical reactor 1, the two quantities of hot gas being introduced at two points, e.g. inlets 16 and combustion chamber 4, spaced from one another along the axis of the reactor. Preferably as shown the furnace comprises three axially aligned zones, the diameters of the first and third being less than that of the second, the first quantity of hot gas being introduced in the first zone, e.g. through inlets 16 in two oppositely directed radial streams, the second quantity of hot gas being introduced in the second zone. The preferred free-oxygen containing gas is air. The furnace may include an annular combustion chamber 11 coaxially surrounding the first zone, one or more conduits, e.g. 13, 14 being adapted to feed a combustible gas mixture into the chamber.

Abstract: 1,264,195. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 10 July, 1969 [15 July, 1968], No. 34811/69. Heading G4A. A data processing system includes a functional unit for performing logical operations in which data normally supplied to a first part of the unit is supplied to another part on detection of an error in the first part. An adder normally receives an already-parity-checked 4-byte word parallel by bit, but if a parity error is detected in any byte. position of the output of the adder, the word is passed through. again, a half-word at a time using the error-free half of the width of the adder if either half is error-free or a byte at a time using the (first) error-free quarter of the width if neither half is error-free but at least one quarter is. (As a modification, two error-free quarters may be used.) The data was saved in auxiliary registers in case of error, and is passed from the registers in the correct position using inter-register transfer with shift by gating. The adder output is reconstituted into one-word parallel form. The above operations can be achieved by inhibiting the output of a microprogramme store controlling the system, on detection of error, so that the next microinstruction is taken from address zero, and using latches, set to indicate which halves and quarters of the adder are error-free (if any). If a further error occurs the system may adjust the data flow width again. The latches are reset when the whole word has been processed. If a predetermined. number of errors have been counted, this reset is inhibited, and an error signal is forced on any further attempt to use the adder, since presumably the error is not transient. Thus no further attempt is made to use the full data flow width. In a second embodiment, the unit is a parallel adder with two inputs, each normally receiving a word in parallel, but the data flow width can be halved as above on error. A carry trigger is provided for each half. Error correction facilities could be provided, data flow width reduction being used only in the case of uncorrectable errors. Processing of the word need not be restarted at the beginning on error: the data passed through the error-free portions could be retained and only the other data recycled.

Abstract: 1288479 Magneto-optic storage arrangements SIEMENS AG 8 July 1970 [9 July 1969] 33092/70 Heading H3B An optical readout system in a magnetooptic data store has a pair of light detector arrangements in the path of a polarized light readout beam, one detector arrangement giving a higher output for a stored " 1 " than for a " 0 ", while the other gives a lower output for a " 1 " than for a " 0 ". The response of the detector arrangements to ambient light is similar, so that when the two outputs are differentially amplified ambient effects are removed. In Fig. 1 each detector arrangement comprises an analyser and a photodetector, A1 and D1, or B1 and D2. The readout light from source L passes through lens LS, linear polarizer P, magnetic storage sheet S, and is incident on beam splitter G. The two analysers Al and B1 are arranged with their planes of polarization at an angle to one another, A1 blocking " 0 " signals and B1 blocking " 1 " signals. The outputs from the two photodetectors are combined in differential amplifiers (not shown). In Fig. 2, two plates A2 and B2 are arranged at the Brewster angle to the readout beam, but are so oriented relative to one another that A2 only reflects light representing a " 1 ", while B2 only reflects for a " 0 " beam. The outputs of the photodetectors are combined as before. When a matrix is being read, two analysers or Brewster plates may be used with two arrays of photodetectors. The Kerr reflection effect may be used in place of the Faraday transmission effect shown in the figures.

Abstract: 1296861 Data processing HONEYWELL Inc 12 Nov 1969 [30 Dec 1968] 55423/69 Heading G4A A digital data processing system comprises a number of registers 40A-40F (e.g. working registers of a computer) each having an auxiliary register 39A-39B into which its contents can be transferred, the auxiliary registers being connected in a ring like a shift register so that data from registers 40A-40F can be shifted through a display device 30 or into reserve memory locations 32. This is used in locating errors or for handling interrupts. Each flip-flop of a register 40A-40F has an auxiliary flip-flop (Fig. 1, not shown) between which information can be exchanged on receipt of appropriate timing signals from a read only memory or a conventional timer 38. It is possible to select that only some of the flip-flops of each register effect this exchange by prewiring and also that only some registers have this facility. The display device 30 has its own shift register 31 connected in series with the auxiliary registers and a lamp 51 for each stage. There are also manual switches 36 for entering new data to some or all of the flip-flops of register 31. Operation.-Timer 38 generates a "snap out" signal for duplicating the state of the flip-flops in registers 40A-40F in the appropriate flipflops of registers 39A-39F. Then timer 38 generates a sentry bit followed by a shift signal which shifts the data to the display area. Here the data is displayed or stored. After switch modification the data is shifted back to its original auxiliary registers (determined by the sentry bit or a shift counter) and then a "snap-in" signal sends the modified data back to its original register 40A-40F. The auxiliary register may be loaded from memory 32, for example data for an interrupt or diagnostic routine. Then the registers 40A-40F can hold the interrupt data while registers 39A-39F hold the register contents before interrupt. Other features.-The flip-flops can be made as integrated circuits and alternative display units are described (Figures 3A-3C, not shown). Register 40F can communicate with magnetic drums, discs or tapes or paper tape and an adder is described (Fig. 2, not shown).
