Abstract: 1,171,166. Heating and cooling garments. UNITED AIRCRAFT CORP. 21 Nov., 1966 [7 Jan., 1966], No. 51953/66. Heading A3V. [Also in Division D1] A garment for warming or cooling a wearer has a plurality of tubes supported on an innermost layer which at least at the sides is of stretchable material. In a suit (Fig. 1, not shown) strips of stretch material extend from ankle to armpit and wrist to shoulder at each side. There may also be stretchable inserts at e.g. the knee. In the jerkin shown in which the entire tube-supporting layer is stretchable a crotch piece 26 for preventing riding-up is detachably connected at the front and back by means of filamentary hook and loop fastening strips. To distribute the stress on the crotch piece in wear the piece is shaped by a dart 34 at the front and darts (39), (40), Fig. 4 not shown, at the rear. The garment, whether the tube-supporting layer is all or partly stretchable, may have a quilted outer layer comprising a matted fibre layer sandwiched between a non- stretchable outermost layer and a slightly stretchable innermost layer of e.g. nylon tricot. This insulating layer is secured to the tube-supporting layer only adjacent a front sliding clasp fastener and at the sides. In a garment including stretchable side strips fire-resistant strips overlying and underlying each stretchable strip are pleated so as not to interfere with its stretchability. Warming or cooling liquid is fed to the garment through conduits (110) which enter couplings (108) of p.v.c. or similar material Fig. 9 (not shown). The tubes 52, which radiate from a plenum chamber of the coupling, may be tacked directly to the garment, Fig 3. Alternatively tubes (84), Fig. 7 not shown, of p.v.c. are bonded in zig zag formation to short lengths (86) of p.v.c. tape which are sewn to the garment parts cut out for assembly.

Title: Controlling distances between vehicles
IPC: B60K31/00
Filed: 1972-11-13
Abstract: 1373892 Automatic control of vehicles AISIN SEIKI KK 13 Nov 1972 [11 Nov 1971] 52275/72 Heading G3R In a safety device for a vehicle, the distance between the vehicle and a leading vehicle is measured, and an "optimum safety distance", as defined in the specification, is calculated, the vehicle being braked if the measured distance is less than the "optimum safety distance". As shown, a vehicle acceleration/braking control system receives signals e.g. from microwave radar sensors, indicative of the distance S to a preceding vehicle, the relative velocity Vx-Vy of the vehicles and the velocity Vx of the trailing vehicle. From these signals, an "optimum safety" distance D between the vehicles is calculated using the maximum available braking force on each  vehicle, and a "minimum stopping" distance DM of each vehicle is calculated using the actual vehicle braking power. The measured and "optimum" distances S, D are compared, the trailing vehicle being accelerated if S is greater than D, and braked if S is smaller, the acceleration or braking being proportional to the difference between S and D, and inversely proportional to the difference between D and DM. The distance between the vehicles is thus maintained at the "optimum" value. Operational amplifiers and solenoids may be used, Figs. 1 to 4 (not shown).

Abstract: 1285584 Cellular polyester filaments TORAY INDUSTRIES Inc 30 Oct 1969 [30 Oct 1968 12 Feb 1969 (2)] 53334/69 Heading B5B [Also in Division C3] Polyester filaments contain 0À4-5% by weight of a polyalkylene ether and 0À3-3% by weight of a surface-active metal salt, and have fine pores aligned along the filament axis. The polyester is a fibre-forming polyester, preferably one in which at least 60% by weight of the recurring units are ethylene terephthalate units, and may thus be polyethylene terephthalate homopolymer, a copolyester obtained by copolymerizing ethylene terephthalate with a known dihydroxy component, dicarboxylic acid component or hydroxy carboxylic acid component; a polyester blend obtained by melt mixing an ethylene terephthalate homopolymer or copolymer with another homopolyester or copolyester; an ethylene terephthalate copolymer containing amide, urethane, ether, carbonate or other linkages; a fibre-forming polyester other than polyethylene terephthalate; and a fibreforming polyester ether. The polyalkylene ether preferably has a molecular weight greater than 4000. The metal salt may be an alkali metal sulphonate, preferably containing only one sulphonate group which is terminal. The metal salt may be a metal salt of a carboxylic acid, phosphonic acid or sulphinic acid, or a di-metal or mono-metal salt of phosphoric acid or phosphorous acid. The filaments of the invention may be obtained by melt spinning a mixture of a polyester, polyalkylene ether and a surface active metal salt and causing fine pores aligned along the filament axis, to form in the filaments by treating the filaments with warm water or with a dilute aqueous solution of an alkali metal hydroxide to dissolve out some of the polyalkylene ether present in the filaments. In an example a mixture of (A) polyethylene terephthaltae and (B) a 2 : 1 mixture of polyethylene glycol having a number average molecular weight of 20,000 and sodium dodecylbenzenesulphonate, the mixing ratio of (A) to (B) being 92À5 : 7À5 is melt spun and the filaments thereby obtained are drawn at a draw ratio of 3À7 over a hot pin maintained at 100‹C. A wool-like texture is imparted to the drawn filaments by mechanical treatment at 205‹ C., and the filaments thereafter knitted to form a cloth. The cloth is scoured at 80‹C. with a very dilute aqueous solution of a detergent and soda ash and thereafter boiled for 20 minutes with a 0À3 N aqueous solution of sodium hydroxide. On analysis it is found that the proportions of polyethylene glycol in the cloth is 1À8% and the proportion of sodium dodecylbenzene sulphonate is 1À1% by weight. Examination of the treated yarn by optical and electron microscopes showed that minute longitudinal pores or cavities had been formed in the yarn.

Title: Apparatus for counting objects

Filed: 1971-11-24
Abstract: 1321934 Counting objects NATIONAL CASH REGISTER CO 24 Nov 1971 [25 Feb 1971] 54570/71 Heading G4D In an apparatus for counting articles such as parcels they are fed past a row of sensors by a conveyer, the sensors detect the pattern of parcels lying over them, this pattern is sampled at intervals and the current pattern is compared with the immediately preceding pattern to detect when the leading or trailing edges of parcels pass over the sensors, these being counted to give an indication of the number of parcels passing the sensors. Such an apparatus is suitable for counting parcels, &c. which are side by side, in contact or overlapping one another on the conveyer. The sensors are a row of 36 photo-cells extending across the conveyer and lit (logic 0) by a lamp but dark (logic 1) when parcels pass over them. Every 36 clock pulses of a timing oscillator the 36 bit data word produced by the photo-cells is read into a first register and each succeeding clock pulse it is shifted bit by bit into a second register. The last six bits from each register are fed to a data processing apparatus (Fig. 4, not shown) at each clock pulse; this compares the data with a set of equation which represent the various attitudes of parcels approaching the cells and yields an output pulse whenever it recognizes the leading or trailing edges of a parcel. A separate count is kept of leading and trailing edges and a comparison made, the largest value being loaded rapidly into a downcounter at a time when no parcels lie over the cells. The downcounter then counts slowly back to zero incrementing a mechanical counter at each count. In the event that there is always a parcel present for 2<SP>9</SP> clock pulses a relay is operated to stop the conveyer until there is a gap; this prevents the counters overrunning and ensures that errors are not introduced by photo-cells remaining continuously obscured by dirt, &c. The conveyer (Fig. 1, not shown) comprises successive belts running at higher and higher speeds so that the parcels are spread into a single layer as they pass the photo-cells.
