Patent GB-1357136-A (GB)
Title: Device for detecting zero acceleration or deceleration of a moving object
IPC: G01P15/16
Filed: 1971-05-26
Abstract: 1357136 Speed measurement SOC NATIONALE INDUSTRIELLE AEROSPATIALE 26 May 1971 [27 May 1970] 17322/71 Heading G4H To determine whether an aircraft is not decelerating prior to take-off, its average speeds over two adjacent measured distances down the runway are compared and if the second is less than the first speed an arresting runway barrier is raised in the path of the aircraft. Actuation by the aircraft of the first of three equispaced pneumatic sensors on the runway operates contact 3 to energize over contact 8 relays 9 which have different time delays and therefore operate at staggered times. Operation of a relay opens the contacts 14 and the number of relays operated before the second sensor is operated by the aircraft is indicative of the average speed between the first two sensors. The second sensor closes contact 11 to energize over the contacts of relays 9 those relays of a store 20 associated with the relays 9 as yet unoperated, i.e. those at times t p , t p+1  &c., to energize lines such as 42. The second sensor also via contact 25 energizing relay 26 energizes a second set of relays 29 also having staggered time delays. If prior to the energization of the third sensor a relay 29 is energized whose contacts are already energized from an energized relay of store 20, e.g. contacts 39 over line 42, a signal is given over line 44 indicating the second average speed is decreasing to raise the arresting barrier. Operation of the third sensor will close contact 32 to energize relays 38 and 38<SP>1</SP> via relay 35 to reset the store 20 and relays 9. The relays 29 are reset via the contact 70 actuated by the last of relays 29 to actuate. If the aircraft takes off between the second and third sensors extra sensors sense this and reset the system.

Patent GB-671409-A (GB)
Title: Improvements in or relating to the treatment of proteins
IPC: A23J1/14
Filed: 1949-07-01
Abstract: A modified protein is prepared by subjecting an aqueous sludge or suspension of a seed globulin to treatment with a cationic or anionic surface active agent, which is substantially resistant to hydrolysis in an amount insufficient to solubilize the protein, before subjecting the sludge or suspension to a rapid drying step, e.g. spray drying.  The seed globulin may be an unmodified or native protein in which case treatment with the surface active agent effects a modification of the protein or the seed globulin may be previously modified by heating, treatment with acid or alkali, or by dissolving the protein in various organic compounds, e.g. urea, pyrogallic acid, guanidine hydrochloride or a synthetic detergent.  In the case of a ground nut protein about 0.1 per cent by weight of surface active agent gives satisfactory results.  The resulting spray-dried ground nut protein forms a useful paper coating composition when mixed with china clay, calcium sulphate or barium sulphate.  The products are also useful in the production of an oil-bound water paint.  In the examples (a) a ground nut meal from which the bulk of oil has been removed is treated with caustic soda and then with hydrochloric acid and the resulting sludge is treated with sodium dodecylbenzene sulphonate before being spray dried; (b) a soya bean meal is similarly treated with cetyl pyridinium bromide and then spray dried.

Filed: 1965-04-26
Abstract: 1,097,839. Knitting machines. SINGER CO. April 26, 1965 [April 27, 1964], No. 17467/65. Heading D1C. Each pattern drum 61, 62 controlling slides 51, 52 Figure 5, for engaging the jacks to select the needles of a circular machine is indexed twice for each revolution of the needle cylinder. This is achieved by the provision of the ratchet wheels 78, 79 for each drum, Figure 16, and associated pawls 75, 76 which are actuated by linkwork 71, 72, 73 controlled by cams on the cylinder drive gear, oscillating pawl arms 74, 75. The length of the teeth on the ratchet wheels is twice the distance of each index and the cams controlling the linkwork and pawls are diametrically opposed such that each pawl in turn actuates its ratchet wheel to index the drum the distance of half a ratchet wheel tooth. A bluffing member may be associated with each wheel and bluffing of either pawl causes the drum to remain stationary. The bluffing members are controlled by stop mechanism 91 operated from a case drum on the machine. The slides 51 are engaged by levers 101 controlled by jacks 100 in the pattern drum and are normally resiliently urged inwardly to engage the needle jacks to effect selection of the needles. The levers 101 are pivoted at 102 so that the jacks 100 in the drum cause the levers to withdraw their corresponding slides. The slides are also controlled in groups by stops 111 on sliding bars 112 which engage the tail ends 105 of a group of slides when projected to pivot the levers 101 and cause the corresponding slides 51 to be withdrawn from action. The stops 111 are controlled by the bars 112 having projections 117 which are engageable by levers 116 controlled by such rods 115 from a lower pattern drum. The bars 112 are mounted in a support 113 also carrying the levers 116. The butts on the needle jacks are so arranged in groups around the needle cylinder that the slides 51, 52 can be operated in groups without interfering with the operation of the machine. The pattern jacks 100 in the pattern drum are arranged in pairs to correspond with the operationo f the ratchet actuating mechanism and to permit two selections at a feeder to be made for each revolution of the needle cylinder.

Title: Improvements in or relating to fabrics comprising yarns of a copolymer of acrylonitrile and vinylidene chloride
Inventor: GREBBY JOHN WILLIAM
Filed: 1956-06-07
Abstract: Fabrics comprising yarns of an acetone-soluble copolymer of acrylonitrile and vinylidene chloride are stabilized in a desired form by subjection to the action of dry heat at 110-150 DEG  C. or of hot water or wet steam at a temperature not higher than 115 DEG  C. while held in the desired form.  The fabrics, which may be woven or knitted, may be heated while held under tension or in a three-dimensional form, e.g. in a pleated form.  The yarns used may be obtained by dry spinning as described in Specification 709,995 but are preferably obtained by spinning an acetone solution of the copolymer heated for example to 40-60 DEG  C. into a coagulating bath consisting of aqueous acetone containing 8-20% of acetone by weight at 40-53 DEG  C., washing the yarns produced free from acetone, drying below 50 DEG  C., stretching by 5 or more times their original length at 150-200 DEG  C. and setting by heating under tension at for example 120-145 DEG  C.  Compounds such as t-butylcatechol, hydroquinone and dibutyl tin laurate or the substances sold under the Trade names "Stanclere," "Mellite" or "Epikote" (the words "Stanclere" and "Epikote" are Registered Trade Marks) in admixture with a metal salt of a long chain fatty acid, e.g. zinc stearate or calcium stearate may be incorporated in the copolymer to stabilize it against decomposition by heat.  The fabrics treated may contain the acrylonitrile-vinylidene chloride copolymer in association with other artificial or natural yarns, e.g. cotton, regenerated cellulose, acetone-soluble cellulose acetate or cellulose triacetate. Specification 643,198 also is referred to.
