Title: Data transmission receiving and recording
IPC: G11B15/087
Filed: 1977-07-25
Abstract: 1533838 Synchronizing data streams INTERNATIONAL BUSINESS MACHINES CORP 25 July 1977 [2 Aug 1976] 31054/77 Heading G4C [Also in Divisions H3 and H5] A preamble 12, Fig. 2, to a data stream 11 is in the form of electrical synchronizing signals 13, 15, 17 interrupted at intervals by electrical marker signals 14, 16, 18, each marker signal being encoded to represent the length of the interval between that marker signal and the beginning of data 19 and the last marker signal 18 ending at the beginning of data 19 The invention may be applied to data transmission and to data recording using a magnetic recording medium. Each marker signal includes an initial resynchronization signal R and a unique pattern of further signals AA, BB and AB, respectively. In a modification a fourth marker signal is added having the pattern RBA. Each signal R, A and B may be as in U.S.A. Specification 3,641,526 which is referred to. The preamble 12 is recorded on a magnetic record medium 10, Fig. 1, by recording circuits 28 in conjunction with a byte or interval counter 26, two triggers 29, 30, A0 circuits 35, 36 and a data latch 42. Initially the byte counter 26 causes recording circuits to record R, then pulses A0 circuit 35 twice so that AA of the first marker signal 14 is recorded, trigger 29 being set and trigger 30 being reset. The byte counter 26 then causes trigger 29 to be reset and trigger 30 to be set to record BB of the second marker signal 16 via A0 circuit 36. Triggers 29, 30 are then both set to record AB of the third marker signal 18 via A0 circuits 35, 36. Readback apparatus, Figs. 4, 5 (not shown), includes triggers and gates to decode the encoded marker signals using a readback byte counter for timing. A recovery circuit is actuated when the triggers fail to respond to the last marker signal to prevent the beginning of data being lost.

Abstract: 303,967. Venner, D. J. V. Nov. 19, 1927. Road-traffic signals on vehicles.-A pivoted signalling-arm 16 for use on motor-vehicles is moved in one direction or the other by connecting one or other of the cylinder spaces 1, 2 to the induction pipe of the engine by means of a valve 29, which also connects the inoperative cylinder space to the atmosphere. The two pistons 4, 5 are connected by a rod 6 carrying a rack 13 which meshes with a pinion 14 on the spindle of the arm 16. Alternatively, the same suction device may be used to actuate sliding signal arms.

Title: Process for the production of oxygenated organic compounds
Inventor: HEIMSCH ROBERT ARTHUR
IPC: C07C45/50
Filed: 1960-09-09
Abstract: Dehydrated aldols are prepared by contacting an olefin having 2-12 carbon atoms in the molecule with carbon monoxide and hydrogen under a total pressure of at least 1,000 p.s.i. and at a temperature of 100-200 DEG C. in the presence of an oxide, hydroxide, salt or carbonyl of cobalt or iron and an organic salt of manganese. Preferably the catalyst contains 10-90% by weight of the cobalt or iron compound and 90-10% of the manganese salt.  The olefin may be aliphatic, cycloaliphatic such as styrene or vinylcyclohexane. The iron or cobalt compound is preferably the salt of an organic acid having 4-20 carbon atoms, e.g., the stearate, ethylcaproate, dodecanoate, naphtherate, tallate, phthalate, benzoate, maleate or adipate, or the acetylacetonate. Suitable manganese salts are, for example, the stearate, ethyl caproate, dodecanoate, naphthenate and tallate. The reaction may be carried out in the presence of free acids, the salts of which are used as catalyst.  The dehydrated aldols produced may be hydrogenated in the presence of the same catalyst to produce the corresponding saturated alcohols. The process may be carried out in two reactions-the oxonation being carried out in the first to produce the aldehydes which are condensed in the second stage. Preferably the temperature range for the oxonation is 100-140 DEG C., for the condensation 140-160 DEG C. and for the hydrogenation 160-200 DEG C. In the examples propylene is converted to 2-ethyl -2- hexanol which may be hydrogenated to give the corresponding saturated alcohol.ALSO:A catalyst for the production of dehydrated aldols from olefines comprises an oxide, hydroxide, salt or carbonyl of cobalt or iron and an organic salt of manganese.  The catalyst preferably contains 10-90% by weight of each component.  The iron or cobalt compound is preferably the salt of an organic acid having 4-20 carbon atoms, e.g. the stearate, a -ethylcaproate, dodecanoate, naphthenate, tallate, phthalate, benzoate, maleate or adipate, or the acetylacetonate.  Suitable inorganic salts are, for example, the nitrate, carbonate, chloride or sulphate. Suitable manganese salts are, for example, the stearate, a -ethylcaproate, dodecanoate, naphthenate or tallate.  If desired some of the free acids corresponding to the salts used may be present.

Abstract: 1,111,424. Doffing wound balls. CROON & LUCKE MASCHINENFABRIK G.m.b.H. 23 July, 1965 [23 April, 1965], No. 31525/65. Headings D1D, D1F and D1J. A ball winding machine of the typefor example as in Specification 1,060,881- having a gripper arranged to remove a wound ball from its winding head and to drop it into a receptacle 8 is modified by the inclusion of a plate 11 which is pivoted into a position above receptacle 8 to deflect the ball into a second receptacle 9 if the ball contains too many knots. Thread 59 being wound passes between a semi-circular member (55) and a resilient member of a thread feeler F and each knot in the thread causes the resilient ,member to actuate a micro switch in the circuit of an electromagnet. The electromagnet releases a catch member from engagement with a bar 36 which moves under the action of springs 38a 38b one notch to the left for each knot before the catch re-engages the bar. An. arm 23 pivoted at 24 carries a rider 29 the position of which is adjustable depending on the acceptable number of knots and which when engaged by a bolt 37 on bar 36 causes arm 23 to pivot and thus rod 12 to be pulled away from a locking position with disc 15 of plate 11 so that the plate falls under gravity into the ball deflecting position. After a wound ball has been doffed a cam disc 21 is rotated to push rod 16 upwardly to return plate 11 to the locking position.

Title: Colour photographic silver halide materials

Filed: 1971-07-09
Abstract: 1350249 Photographic silver halide material EASTMAN KODAK CO 9 July 1971 [13 July 1970] 32327/71 Heading G2C A photographic material comprises a support bearing at least one spectrally sensitized silver halide emulsion layer under which is coated a lower blue-sensitive silver halide emulsion layer and over which is coated, in order, a yellow filter layer which transmits some blue light and a upper blue-sensitive silver halide emulsion layer. Green and red-sensitized emulsion layers may be coated under the yellow filter layer. Each of the green and redsensitized emulsion layers may consist of an adjacent pair of layers of emulsions of different speeds. The yellow filter layer may be such that the lower blue-sensitive emulsion layer receives an exposure from 10-50 per cent of the exposure received by the upper blue-sensitive layer. A colour coupler may be present in each emulsion layer or the material may be processed with coupler-containing colour developing solutions. The upper blue-sensitive emulsion layer may have a turbidity which is less than that of the lower blue-sensitive emulsion layer. One of the emulsion layers or layer pairs may be used to record an infrared image, this giving in the processed material a visible image of some chosen colour. By placing part of the bluesensitive emulsion under one or both of red- and green-sensitive emulsion layers, for instance, the amount of light-scatter occurring before light of an exposing image reaches the red- and/ or green-sensitive emulsion layers is reduced and the sharpness is thus increased.

For example, cyclohexanol and its homologues, or their esters; tetrahydronaphthalene; decahydronaphthalene; and tetrahydronaphthol may be used. The surface of the rubber or rubber-coated article is first treated, once or several times, with one of the mutual solvents, preferably cyclohexanol, applied by brushing or spraying or otherwise.

Strips or pieces of cellulose derivative may be applied to rubber surfaces by using the mutual solvent as an adhesive agent. The process is applicable to waterproofed fabrics such as motor car hood fabrics, boots and shoes, surgical appliances and rubber balls.
